Introduction: In squamous cell carcinoma of the esophagus (ESCC), therapeutical options in 2nd-line treatment are scarce with immune checkpoint inhibition being the only approved one. Ramucirumab/paclitaxel is an approved 2nd-line treatment in metastatic esophagogastric adenocarcinoma. We assessed safety and efficacy of ramucirumab/paclitaxel for ESCC. Methods: This prospective, randomized, open-label, multicenter, phase II trial evaluated paclitaxel (80 mg/m2 days 1, 8, 15) plus ramucirumab (8 mg/kg days 1, 15) (investigational arm A) versus paclitaxel alone (80 mg/m2 days 1, 8, 15) (standard arm B), both q4w, in advanced/metastatic ESCC refractory or intolerant to fluoropyrimidine and platinum-based drugs. Primary endpoint was overall survival (OS) rate at 6 months. Results: From 3/2019 to 4/2021, 21/186 planned patients were included (arm A 11 patients; arm B 10 patients) in 9 German centers. Due to slow accrual, the study was terminated prematurely. OS at 6 months was 72.7% for ramucirumab/paclitaxel and 50.0% for paclitaxel. The study design did not allow statistical comparison of the arms. PFS (3.8 vs. 3.5 months), OS (12.1 vs. 9.2 months), ORR (18.2% vs. 20.0%) and DCR (54.5% vs. 60.0%) were comparable in both arms. Most common treatment-related adverse events (TRAEs) in arm A were leucopenia (54.5%), fatigue (27.3%), and peripheral sensory neuropathy (18.2%). 27.3% in arm A and 50.0% in arm B had TRAEs ≥ grade 3. Conclusion: Ramucirumab/paclitaxel shows an acceptable tolerability and numerically improved OS at 6 months. Due to the small number of patients, the current trial must be considered exploratory and more data are needed in this indication. Plain Language Summary: Metastatic and unresectable ESCCs still show poor prognosis. After failure or intolerance to first-line therapy, treatment options are limited and checkpoint inhibitors are the only approved therapeutic option. Our study adds further evidence to the use of antiangiogenic drugs in second-line treatment of advanced ESCC. Ramucirumab in combination with paclitaxel showed numerically improved OS and PFS compared to paclitaxel alone. However, due to the small sample size, the results have to be considered exploratory and more data are needed in this indication. We do not recommend the use of ramucirumab/paclitaxel in second-line treatment of advanced ESCC outside of clinical trials. [ABSTRACT FROM AUTHOR]

Purpose: Based on the comparison of ramucirumab monoclonal antibody with control treatments in randomized controlled trials, this study aims to elucidate the role of ramucirumab monoclonal antibody in cancer therapy and its potential side effects, providing scientific evidence for clinical treatment. Methods: PubMed, Embase, Cochrane, and Web of Science were searched systematically to obtain the trials on ramucirumab in the treatment of gastric or gastroesophageal junction (GEJ) adenocarcinoma up to April 13, 2023. We included randomized controlled trials (RCTs) evaluating the efficacy and safety of ramucirumab as monotherapy and in combination with other chemotherapy agents as interventions for treating gastric or gastroesophageal junction (GEJ) adenocarcinoma. Results: After screening 2200 studies, we finally included 8 eligible studies (involving a total of 3,283 participants). Meta-analysis results showed that compared to the control group, ramucirumab monotherapy significantly improved overall survival (OS) (hazard ratio [HR] = 0.77, 95% confidence interval [CI] [0.67, 0.89]) and progression-free survival (PFS) (HR = 0.48, 95% CI [0.40, 0.58]). Similar results were obtained for ramucirumab combined with paclitaxel. In the treatment combining ramucirumab with paclitaxel, compared to monotherapy, three severe adverse reactions (grade ≥ 3) were observed with significantly increased risks (OR > 2). These include proteinuria (OR = 5.37, 95% CI [1.22, 23.54]), hypertension (OR = 4.02, 95% CI [2.63, 6.14]), and gastrointestinal perforation (OR = 4.64, 95% CI [1.00, 21.60]). Subgroup analysis further indicated that ramucirumab is effective in both non-East Asian and East Asian populations, with East Asian patients more prone to developing proteinuria, while having a lower incidence of hypertension. Additionally, ramucirumab demonstrated comparable efficacy between first-line and second-line treatments, with a higher incidence of proteinuria observed in second-line therapy. Conclusion: Ramucirumab significantly improves the prognosis of patients with gastric or gastroesophageal junction adenocarcinoma. When used in combination with paclitaxel, close monitoring of adverse reactions such as proteinuria (especially in East Asian populations), hypertension (especially in non-East Asian populations), and gastrointestinal perforation is essential.

Background: Docetaxel (DOC) and ramucirumab (RAM) is one of the most effective regimens for advanced non-small cell lung cancer (NSCLC) treatment. In our previous study, baseline anemia was identified as a preventive factor against the development of severe adverse effects during the first treatment cycle. It was hypothesized that anemia directly promotes tumor angiogenesis, leading to the elevation of RAM efficacy with increased DOC delivery to tumors, while reducing DOC delivery to other organs, potentially mitigating severe adverse effects. If this hypothesis is correct, patients with baseline anemia may have better clinical outcomes than those with normal hemoglobin levels. In this study, we aimed to investigate the effect of baseline anemia on the efficacy of DOC + RAM in treating advanced NSCLC in a real-word setting. Methods: Patients with advanced NSCLC receiving DOC + RAM (n = 72) were retrospectively assessed. They were categorized into a control group with normal baseline hemoglobin levels and an anemia group with baseline anemia. The primary endpoint was progression-free survival (PFS) evaluation. Results: Patients in the anemia group had a significantly shorter PFS than that of patients in the control group (median PFS: 3.2 and 6.2 months; 95% confidence interval [CI]: 2.2–4.8 and 4.3–9.9 months, respectively;P = 0.008). In addition, the disease control rate in the anemia group was 65.8%, which was significantly lower than that in the control group (93.6%; P = 0.007). Overall survival tended to be shorter in patients with anemia than in controls, although the difference was not statistically significant (P = 0.07). Multivariate Cox hazard analysis suggested that baseline anemia was a singular risk factor for poor PFS (adjusted hazard ratio 1.84, 95% CI 1.08–3.13; P = 0.02). The incidence of severe adverse effects did not differ between the two groups. Conclusions: This study suggests that the PFS of patients with anemia treated with DOC + RAM for advanced NSCLC is shorter than that of those without the symptoms. [ABSTRACT FROM AUTHOR]

Ramucirumab (RAM) has been approved for the treatment of non‐small cell lung cancer (NSCLC). Here, we report two cases of RAM‐induced ascites with epidermal growth factor receptor‐mutant NSCLC. Patient 1, a 72‐year‐old man, developed ascites 20 months after erlotinib (ERL) and RAM administration, which resolved after their discontinuation and performing paracentesis. Patient 2, an 83‐year‐old woman, developed ascites 9 months after ERL and RAM administration, which resolved after RAM discontinuation and furosemide administration. Ramucirumab administration can cause ascites due to increased hepatic sinusoidal pressure. Clinicians should be aware of RAM‐induced ascites in patients with NSCLC and should appropriately manage it.

Purpose: Ramucirumab (RAM) is recommended as premedication with H1-receptor antagonists (H1RA) to prevent infusion-related reactions (IRRs). However, RAM is a human antibody with a low incidence of IRRs. We evaluated the noninferiority of non-H1RA (dexamethasone [DEX] alone) premedication to H1RA (plus DEX) premedication in terms of IRRs in patients with gastric cancer receiving RAM plus nanoparticle albumin-bound paclitaxel (nab-PTX). Methods: This was a noninferiority, multicenter, retrospective trial conducted in three Japanese centers to assess the incidence of IRRs in patients receiving RAM plus nab-PTX for gastric cancer between 2018 and 2023. Patients with gastric cancer receiving RAM plus nab-PTX were divided into groups with and without H1RA premedication. The incidence of IRRs was compared between the two groups. Results: Ninety patients were evaluated, with non-H1RA and H1RA premedications in 43 and 47 cases, respectively. After the first dose of RAM, IRRs were not observed in either group. IRRs during the overall doses were 0% for non-H1RA premedication and 2.1% for H1RA premedication (90% confidence interval (CI): –5.6%–1.3% for each comparison). The upper limit of the 90% CI (1.3%) did not exceed the noninferiority margin (Δ) of + 10% and therefore met the noninferiority criteria. Conclusion: RAM plus nab-PTX for gastric cancer with DEX premedication may be possible without H1RA premedication. [ABSTRACT FROM AUTHOR]

Background Early studies showed promise of combined anti-epidermal growth factor receptor (EGFR) plus anti–vascular endothelial growth factor (VEGF) antibodies for advanced colorectal cancer (CRC), yet this was later rejected as toxic and ineffective in studies not selected for RAS status. We studied advanced KRAS wild-type CRC, as second-line treatment, using irinotecan-cetuximab with or without the anti-VEGF receptor antibody ramucirumab. Methods Patients with 1 prior regimen including fluoropyrimidine, oxaliplatin, and bevacizumab, with KRAS wild-type tumors were stratified by Eastern Cooperative Oncology Group Performance Score, time since last chemotherapy, and progression on oxaliplatin to irinotecan-cetuximab (IC) (180 mg/m2 and 500 mg/m2 every 2 weeks) vs modified ICR (irinotecan-cetuximab with ramucirumab 150 mg/m2 and 400 mg/m2 plus 6 mg/kg, respectively). A total of 102 patients were compared for progression-free survival (PFS) as primary endpoint (85% power for 70% improvement in median PFS from 4.5 to 7.65 months). Results Of the 102 enrolled, 44 treated with irinotecan-cetuximab and 45 with modified ramucirumab were evaluable. Median PFS was 6.0 months vs 9.2 months, respectively (hazard ratio = 0.75, P = .07; statistically significant by study design for P  < .128). Response rate was 23% vs 36% (P = .27), and disease-control rate was 52% vs 73% (P  = .05). Grade 3 or higher toxicity was equivalent. Overall survival was not significantly different at approximately 19 months. Conclusion Previous phase 3 trials without RAS genotyping rejected combining anti-epidermal growth factor receptor and anti-VEGF drugs. In this randomized multicenter phase 2 study for KRAS wild-type CRC (all previously bevacizumab treated), the addition of ramucirumab to irinotecan and cetuximab improved PFS and disease control rate, showing the combination is feasible and effective. Further, phase 3 trials with appropriate patient-selection are required. (NCT01079780) [ABSTRACT FROM AUTHOR]

Introduction: The aim of this study was to provide a review of the clinical evidence for use of ramucirumab (RAM) plus folinic acid (leucovorin), fluorouracil (5-FU), and irinotecan (FOLFIRI) or irinotecan as second-line treatment in gastroesophageal adenocarcinoma (GEA). Methods: A systematic and comprehensive search of PubMed was performed to identify phase 2 clinical trials or retrospective studies using RAM plus FOLFIRI or irinotecan in GEA, including abstracts from major congresses, in addition to published manuscripts. An aggregated review and meta-analysis was performed to assess the effectiveness (overall response rate [ORR] as primary outcome) and safety data of RAM plus FOLFIRI or irinotecan. ORR for each study was calculated with 95% confidence interval estimated from normal approximation. To generate the combined ORR with 95% confidence interval, random-effects meta-analysis was conducted to synthesize response data from available studies. Results: Six studies were identified with non-overlapping populations, 3 phase 2 clinical trials and 3 retrospective studies. Across these studies the ORR ranged from 22% to 38%, and pooled ORR was 25.4%. Two of the 3 studies reported better ORR in patients pretreated with taxanes followed by RAM plus FOLFIRI. Treatment with RAM plus FOLFIRI or irinotecan was well tolerated. Neutropenia and diarrhea were the most common adverse events reported across studies. Conclusion: The studies examined in this review suggest that RAM plus FOLFIRI or irinotecan have activity in previously treated GEA irrespective of prior-taxane use. Overall, RAM plus FOLFIRI or irinotecan was well tolerated with no new safety concerns identified beyond established profiles for these regimens. [ABSTRACT FROM AUTHOR]

Summary: This study aimed to complement the results of the REACH-2 study by prospectively evaluating the safety and efficacy of ramucirumab in advanced hepatocellular carcinoma (HCC) in a real-world setting. This was an open-label, nonrandomized, multicenter, prospective study conducted at 13 institutions in Japan (jRCTs031190236). The study included Child–Pugh Class A patients with advanced HCC who had received pretreatment with atezolizumab plus bevacizumab (Atez/Bev) or lenvatinib. Ramucirumab was introduced as a second-line treatment after Atez/Bev or lenvatinib and as a third-line treatment after Atez/Bev and lenvatinib. Between May 2020 and July 2022, we enrolled 19 patients, including 17 who received ramucirumab. Additionally, seven patients received lenvatinib, another seven patients received Atez/Bev, and three patients received Atez/Bev followed by lenvatinib as prior treatment. The primary endpoint was a 6-month progression-free survival (PFS) rate, which was 14.3%. The median PFS and overall survival were 3.7 and 12.0 months, respectively. The most common grade ≥ 3 adverse events (AEs) were hypertension (23.5%), proteinuria (17.6%), and neutropenia (11.8%). The discontinuation rate due to AEs was 29.4%. Six patients progressed from Child–Pugh A to B after treatment with ramucirumab. Thirteen patients were eligible for post-ramucirumab treatment, including systemic therapy. Despite the limited number of patients, the efficacy of ramucirumab was comparable to that observed in the REACH-2 study when used after lenvatinib and Atez/Bev. However, the incidence of AEs was higher than that in the REACH-2 study. [ABSTRACT FROM AUTHOR]

Introduction: The risk of thromboembolic events developing limits the dose of antiangiogenic agents, thereby reducing their efficacy. This retrospective study therefore sought to identify predictors for the development of antiangiogenic agent-induced thromboembolic events and to elucidate whether differences in the likelihood of thromboembolic events exist between different antiangiogenic agents or cancer types, to guide future strategies for optimizing safety, efficacy, and quality of life in patients receiving chemotherapy. Methods: This study retrospectively investigated 468 cancer patients who received chemotherapy with bevacizumab, ramucirumab, or aflibercept at our outpatient chemotherapy center between December 2016 and April 2022. Variables related to the development of thromboembolic events were extracted from the medical records, and multivariate logistic regression analysis was performed to identify predictors for the development of thromboembolic events. The Wilcoxon/Kruskal-Wallis test was used to detect significant differences between groups. Results: Significant factors included serum albumin level (odds ratio [OR] = 0.363, 95% confidence interval [CI] = 0.193–0.685; p = 0.0017) and diabetes mellitus (OR = 5.356, 95% CI = 1.711–16.769; p = 0.0039). Renin-angiotensin system inhibitors (OR = 0.307) had low OR, although it was not significant. No difference in the development of thromboembolic events was evident between cancer types (p = 0.0781), but differences were identified between the three antiangiogenic agents (p = 0.0132). Ramucirumab was associated with a lower likelihood of thromboembolic events. Conclusion: Serum albumin level and diabetes mellitus were identified as significant predictors for the development of antiangiogenic agent-induced thromboembolic events. In addition, the likelihood of thromboembolic events did not differ between cancer types but differed between antiangiogenic agents. Plain Language Summary: This retrospective study was designed to identify predictors for the development of antiangiogenic agent-induced thromboembolic events and to elucidate whether differences in the likelihood of thromboembolic events exist between different antiangiogenic agents or cancer types.

FOLFOX plus nivolumab represents a standard of care for first‐line therapy of advanced gastroesophageal cancer (aGEC) with positive PD‐L1 expression. The efficacy of second‐line VEGFR‐2 inhibition with ramucirumab (RAM) plus chemotherapy after progression to immunochemotherapy remains unclear. Medical records of patients with aGEC enrolled in the randomized phase II AIO‐STO‐0417 trial after treatment failure to first‐line FOLFOX plus nivolumab and ipilimumab were retrospectively analyzed. Patients were divided into two groups based on second‐line therapy: RAM plus chemotherapy (RAM group) or treatment without RAM (control group). Eighty three patients were included. In the overall population, progression‐free survival (PFS) in the RAM group was superior to the control (4.5 vs 2.9 months). Responders (CR/PR) to first‐line immunochemotherapy receiving RAM containing second‐line therapy had prolonged OS from start of first‐line therapy (28.9 vs 16.5 months), as well as second‐line OS (9.6 vs 7.5 months), PFS (5.6 vs 2.9 months) and DCR (53% vs 29%) compared to the control. PD‐L1 CPS ≥1 was 42% and 44% for the RAM and the control, respectively. Patients with CPS ≥1 in the RAM group showed better tumor control (ORR 25% vs 10%) and improved survival (total OS 11.5 vs 8.0 months; second‐line OS 6.5 vs 3.9 months; PFS 4.5 vs 1.6 months) compared to the control. Prior exposure to first‐line FOLFOX plus dual checkpoint inhibition followed by RAM plus chemotherapy shows favorable response and survival rates especially in patients with initial response and positive PD‐L1 expression and has the potential to advance the treatment paradigm in aGEC.

Introduction: Gastric cancer has the highest incidence and mortality in Eastern Asia. The efficacy and safety of ramucirumab (RAM) monotherapy or in combination with paclitaxel (PTX) for patients with unresectable advanced or metastatic gastric/gastroesophageal junction adenocarcinoma (G/GEA) have been established in clinical trials. To assess the effectiveness and safety of RAM or RAM-based therapy as a second-line treatment in real-world clinical practice in Eastern Asia and to pave the way for future research, a systematic literature review (SLR) was conducted. Methods: Studies published between January 2014 and December 2021 were identified in PubMed, Embase, Cochrane Library, CNKI, Wanfang, and CBM databases. Results: This SLR included 23 studies from Japan and South Korea, of which 22 were retrospective and 11 were full-text articles. Most studies investigated RAM + PTX (range of median overall survival [mOS] 7.4–12.2 months; median progression-free survival [mPFS] 3.35–7.0 months). Data were limited for RAM, RAM + albumin-bound paclitaxel, and RAM + taxane. RAM + PTX was associated with longer survival (mOS 9.3–12.2 months vs. 5.2–9.7 months; mPFS 4.1–5.1 months vs. 3.0–4.1 months) than PTX. Patients with prior anti-programmed cell death 1 (anti-PD-1) exposure experienced longer mPFS (4.8 vs. 3.4 months) from RAM + taxane than those without prior anti-PD-1 exposure. Few patients (3.3–6.3%) discontinued RAM or RAM-based therapy because of adverse events (AEs). Hematological toxicities were most frequently occurring AEs and no new safety signals were identified compared to clinical trials. Conclusion: RAM + PTX as a second-line treatment is effective and associated with an acceptable toxicity profile in patients with advanced or metastatic G/GEA in real-world settings of Japan and South Korea. More studies are recommended to further evaluate effectiveness and safety of RAM or RAM-based therapy, especially after anti-PD-1 therapy, in a wider Eastern Asian population.

Background A history of pre-administration of immune checkpoint inhibitors has been reported to be associated with good outcomes of ramucirumab (RAM) plus docetaxel (DOC) combination therapy for advanced non-small-cell lung cancer (NSCLC). However, existing knowledge on the clinical significance of RAM and DOC following combined chemoimmunotherapy is limited. Therefore, we evaluated the efficacy and safety of RAM plus DOC therapy after combined chemoimmunotherapy and attempted to identify the predictors of its outcomes. Patients and Methods This multicenter, prospective study investigated the efficacy and safety of RAM plus DOC after combined chemoimmunotherapy. The primary endpoint was progression-free survival (PFS). Secondary endpoints were the objective response rate (ORR), disease control rate (DCR), overall survival (OS), and incidence of adverse events. An exploratory analysis measured serum cytokine levels at the start of treatment. Results Overall, 44 patients were enrolled from 10 Japanese institutions between April 2020 and June 2022. The median PFS and OS were 6.3 and 22.6 months, respectively. Furthermore, the ORR and DCR were 36.4% and 72.7%, respectively. The high vascular endothelial growth factor D (VEGF-D) group had a significantly shorter PFS and OS. A combination of high VEGF-A and low VEGF-D levels was associated with a longer PFS. Conclusion Our results showed that RAM plus DOC after combined chemoimmunotherapy might be an effective and relatively feasible second-line treatment for patients with advanced NSCLC in a real-world setting.

Aim: Sequential therapies are essential to extend overall survival (OS) in patients with unresectable hepatocellular carcinoma (HCC). Several second‐line treatments with molecular target agents have shown survival benefits. However, the significance of post‐progression survival (PPS) in extending OS in patients with HCC given such treatments remains uncertain. Methods: Through a systematic review of the literature in the PubMed database, this study investigated the correlation between PPS and OS and that between progression‐free survival (PFS) and OS in patients with HCC given second‐line treatments. Results: In total, 3935 patients who had received second‐line treatment with regorafenib, ramucirumab, or cabozantinib, which are approved molecular target agents, were identified. In the patients treated with regorafenib, PPS showed a strong correlation with OS (R2 = 0.729, R = 0.854, p < 0.001) whereas PFS showed a weak correlation (R2 = 0.218, R = 0.467, p = 0.021). In the patients treated with ramucirumab, PPS showed a strong correlation with OS (R2 = 0.800, R = 0.894, p = 0.016) whereas PFS showed a negligible correlation (R2 = 0.020, R = 0.140, p = 0.791). In the patients treated with cabozantinib, PPS showed a strong correlation with OS (R2 = 0.856, R = 0.925, p = 0.003) as did PFS (R2 = 0.946, R = 0.973, p < 0.001). Conclusions: PPS plays a more significant role than PFS in extending OS in patients given second‐line treatment for unresectable HCC. Sequential therapies after disease progression in second‐line treatment are essential to acquire good OS. Maintenance of hepatic reserve function and the patient's general condition is essential during systemic treatments for unresectable HCC. [ABSTRACT FROM AUTHOR]

Simple Summary: This review summarizes the history and current clinical applications of antiangiogenic treatment. It specifically discusses current challenges of the treatment and opportunities for optimization, including normalization of the tumor vasculature, modulation of milieu-dependent heterogeneity of the vasculature, and targeting of angiocrine protein functions. The vasculature is a key player and regulatory component in the multicellular microenvironment of solid tumors and, consequently, a therapeutic target. In colorectal carcinoma (CRC), antiangiogenic treatment was approved almost 20 years ago, but there are still no valid predictors of response. In addition, treatment resistance has become a problem. Vascular heterogeneity and plasticity due to species-, organ-, and milieu-dependent phenotypic and functional differences of blood vascular cells reduced the hope of being able to apply a standard approach of antiangiogenic therapy to all patients. In addition, the pathological vasculature in CRC is characterized by heterogeneous perfusion, impaired barrier function, immunosuppressive endothelial cell anergy, and metabolic competition-induced microenvironmental stress. Only recently, angiocrine proteins have been identified that are specifically released from vascular cells and can regulate tumor initiation and progression in an autocrine and paracrine manner. In this review, we summarize the history and current strategies for applying antiangiogenic treatment and discuss the associated challenges and opportunities, including normalizing the tumor vasculature, modulating milieu-dependent vascular heterogeneity, and targeting functions of angiocrine proteins. These new strategies could open perspectives for future vascular-targeted and patient-tailored therapy selection in CRC. [ABSTRACT FROM AUTHOR]

Background: Atezolizumab is superior to docetaxel for patients with advanced non-small-cell lung cancer (NSCLC) who are pretreated with platinum-based chemotherapy based on the POPLAR and OAK trials. However, patients who received prior immunotherapy were excluded from these trials. The standard of care second-line therapy for these patients remains to be docetaxel with or without ramucirumab. The efficacy and safety of atezolizumab as a subsequent therapy in immunotherapy-pretreated patients are unknown. Methods: We conducted a retrospective study of all patients with locally advanced or metastatic NSCLC who were pretreated with immunotherapy at Mayo Clinic Jacksonville and Rochester from 2016 to 2022. Patients who received subsequent therapy of atezolizumab alone (Atezo), docetaxel (Doce), or docetaxel + ramucirumab (Doce+Ram) were included. Results: In this cohort of 165 patients, 12.7% (n=21), 49.1% (n=81), and 38.2% (n=63) patients received subsequent Atezo, Doce, and Doce+Ram, respectively. 1-year landmark progression-free survival (PFS) were 23.8%, 6.2%, and 3.2% (p=0.006), and 2-year landmark PFS were 14.3%, 0%, and 0% (p<0.0001), in the Atezo, Doce, and Doce+Ram groups, respectively. About 20% patients with positive PD-L1 had durable response to atezolizumab. The Atezo group showed significantly greater overall survival (OS) improvement over Doce group (median OS 17.7 vs. 7.7 months, HR 0.47, 95% CI 0.29 - 0.76, p=0.008), and over Doce +Ram group (median OS 17.7 vs. 8.9 months, HR 0.55, 95% CI 0.32 - 0.95, p=0.047). 4 of 21 (19%) patients in the Atezo group developed immune-related adverse events (irAE). Conclusion: We observed statistically significant and clinically meaningful overall survival benefits of atezolizumab monotherapy compared with docetaxel +/- ramucirumab in patients with advanced NSCLC who were pretreated with immunotherapy. The survival benefit seems to be mainly from PD-L1 positive patients. Subsequent immunotherapy with Atezolizumab did not increase irAE rate. [ABSTRACT FROM AUTHOR]

Background: Recent trials have reported a median overall survival (OS) of 11–17 months in patients with advanced gastric cancer (AGC). However, it is unclear how recently approved drugs contribute to patient prognosis. Objectives: We aimed to evaluate the characteristics and survival in patients with AGC over the past 15 years. Design: Retrospective study. Methods: We evaluated data of 1355 patients with AGC who received first-line chemotherapy between January 2005 and March 2019 at a single institution. We compared the characteristics and survival rates across four periods: January 2005–December 2007 (period A), January 2008–February 2011 (period B), March 2011–May 2015 (period C), and June 2015–March 2019 (period D). The median follow-up duration was 13.1 months, with 312, 333, 393, and 317 patients in periods A, B, C, and D, respectively. Results: There were no significant differences in patient characteristics between the four periods, except for the proportion of patients who underwent prior gastrectomy and human epidermal growth factor receptor 2 (HER2) testing. Patients in period D had significantly longer OS than those in period A [median: 15.7 versus 12.4 months; adjusted hazard ratio (aHR): 0.79; p = 0.02]. The mean OS in patients with liver metastasis (LM) in period D was remarkably longer than that in patients in period A (median: 19.3 versus 12.4 months; aHR: 0.61; p < 0.01), while that in patients with peritoneal metastasis showed limited improvement. Conclusion: Clinical strategy changes, including gastrectomy, HER2 testing, and approval of new drugs, may be associated with improved OS in patients with AGC. In the last 4 years, a remarkable improvement has been observed in patients with LM. [ABSTRACT FROM AUTHOR]

Although conventional combination chemotherapies for advanced gastric cancer (GC) increase survival, such therapies are associated with major adverse effects; more effective and less toxic treatments are required. Combinations of different anti-cancer drugs, for example, paclitaxel plus ramucirumab, have recently been used as second-line treatments for advanced GC. This study evaluated how copy number variations of the MET gene, MET mutations, and MET gene and protein expression levels in human GC cells modulate the susceptibility of such cells to single-agent (tepotinib, ramucirumab, or paclitaxel) and doublet (tepotinib-plus-paclitaxel or ramucirumab-plus-paclitaxel treatment regimens. Compared with ramucirumab-plus-paclitaxel, tepotinib-plus-paclitaxel better inhibited the growth of GC cells with MET exon 14 skipping mutations and those lacking MET amplification but containing phosphorylated MET; such inhibition was dose-dependent and associated with cell death. Tepotinib-plus-paclitaxel and ramucirumab-plus-paclitaxel similarly inhibited the growth of GC cells lacking MET amplification or MET phosphorylation, again in a dose-dependent manner, but without induction of cell death. However, tepotinib alone or tepotinib-plus-ramucirumab was more effective against c-MET-positive GC cells (>30 copy number variations) than was ramucirumab or paclitaxel alone or ramucirumab-plus-paclitaxel. These in vitro findings suggest that compared with ramucirumab-plus-paclitaxel, tepotinib-plus-paclitaxel better inhibits the growth of c-MET-positive GC cells, cells lacking MET amplification but containing phosphorylated MET, and cells containing MET mutations. Clinical studies are required to confirm the therapeutic effects of these regimens. [ABSTRACT FROM AUTHOR]

In Japan, systemic chemotherapy is the standard treatment for unresectable, advanced, or recurrent gastric cancer. However, numerous patients with gastric cancer do not receive late-line treatment because of the rapid progression of gastric cancer. Additionally, late-line treatments, such as nivolumab, trifluridine tipiracil (FTD/TPI), or irinotecan, have limited effects on improving clinical symptoms and delaying the onset of symptoms associated with cancer progression. Recently, a combination of FTD/TPI and ramucirumab was reported to have a high response rate in late-line treatment; however, owing to patient selection bias and a high rate of hematologic toxicity in that previous study, this regimen may not be feasible in real-world clinical applications. Our objective is to conduct a single-arm phase II study to assess the safety and efficacy of FTD/TPI plus ramucirumab combination therapy for gastric cancer after third-line treatment under real-world clinical conditions. This study will recruit 32 patients according to eligibility criteria and administer FTD/TPI (35 mg/m2 ) and intravenous ramucirumab (8 mg/kg). The primary endpoint will be the time to treatment failure. The secondary endpoints will include the overall survival time, progression-free survival time, overall response rate, disease control rate, relative dose intensity, and incidence of adverse events. The results will add new insights for improving the late-line treatment of advanced gastric cancer. [ABSTRACT FROM AUTHOR]

Background: Several options for second-line therapy are available for patients with advanced non-small cell lung cancer (NSCLC); however, the optimal therapy remains unclear. Docetaxel (DTX) monotherapy and DTX plus ramucirumab (RAM) are the recommended second-line treatment options. However, the efficacy of these treatments remains unsatisfactory. The aim of this study was to identify the clinical characteristics of patients with NSCLC who respond to DTX or DTX + RAM and factors that predict response. Methods: Patients with NSCLC treated with DTX or DTX + RAM after second-line therapy were retrospectively analyzed. Patients were compared with those who responded or did not respond to the post-treatment efficacy assessment. Results: Of 53 patients, 12 (22.6%) had lung cancer that responded to DTX or DTX + RAM therapy (response group). Multivariate analysis identified the absence of immune checkpoint inhibitors (ICIs) in the immediate prior therapy and a reduced dose of DTX after the second cycle as significant independent risk factors predicting nonresponse to DTX and DTX + RAM therapy in patients with NSCLC. The overall survival was significantly longer in the response group compared to the nonresponse group (p = 0.016). Conclusions: Our results suggest that DTX and DTX + RAM therapies immediately after treatment with ICI-containing regimens as well as continuation of DTX without dose reduction after the second cycle may increase the response rate and prolong survival in patients with NSCLC.

Lung carcinosarcoma is acknowledged as a rare form of lung cancer. Due to its rarity, the inability to conduct large‐scale clinical trials and interventions is currently carried out based on empirical evidence. In this study, we report the case of a 73‐year‐old female patient diagnosed with postoperative recurrence of lung carcinosarcoma. The resected tumor was diagnosed as lung carcinosarcoma, and genetic testing revealed the presence of the epidermal growth factor receptor (EGFR) exon21 L858R. Approximately 2 years postoperatively, the tumor recurred and the patient was treated with erlotinib plus ramucirumab, which were effective in controlling metastatic disease. Erlotinib plus ramucirumab is therefore a treatment option for EGFR mutation‐positive lung carcinosarcoma. [ABSTRACT FROM AUTHOR]

(1) Background: Following the results of RAINBOW and REGARD trials, ramucirumab was approved as the standard second-line treatment for patients with advanced or metastatic gastric or gastroesophageal junction (GEJ) cancer, alone or in combination with paclitaxel. The present study aimed to evaluate the efficacy and safety of ramucirumab in the Romanian population during every-day clinical practice. (2) Methods: A two-center, retrospective, observational study evaluated patients with metastatic gastric and GEJ cancer treated with ramucirumab monotherapy or associated with paclitaxel. The patients were treated between 2018 and 2022 in two Romanian centers as follows: 18 patients underwent treatment with ramucirumab monotherapy, while 51 received the combined treatment regimen. Study endpoints included median progression-free survival (PFS), median overall survival (OS), and the evaluation of treatment-induced adverse events (AEs). (3) Results: In the study cohort (n = 69), the most frequent treatment-induced AE in the ramucirumab plus paclitaxel arm was hematological toxicity; the most common AE for patients treated with ramucirumab monotherapy was fatigue and headache. Overall, the median PFS was 4.7 months (95% CI: 3.4–5.9 months) and median OS was 18.23 months (95% CI: 15.6–20.7 months). PFS was correlated with the number of treatment cycle administrations, Eastern Cooperative Oncology Group performance status at treatment initiation, and metastatic site (visceral vs. peritoneal). OS was correlated with the number of treatment cycles administered and human epidermal growth factor receptor-2 status. (4) Conclusions: The results support the previously described toxicity profile for ramucirumab monotherapy or associated with paclitaxel and demonstrated a relatively superior median PFS.

Based on results of prior trials (TAGS, REGARD, RAINBOW), the combination of ramucirumab beyond progression with TAS‐102 (trifluridine/tipiracil) seems to be promising in advanced esophagogastric adenocarcinoma (EGA). In this multicenter, non‐randomized, open‐label, investigator‐initiated pilot trial, ramucirumab‐pretreated patients with metastatic EGA received a maximum of 4 cycles of ramucirumab (8 mg/kg i.v. on day 1 and 15, Q2W) plus TAS‐102 (35 mg/m2 p.o. bid on day 1‐5 and day 8‐12; Q2W). Primary endpoint was tolerability and toxicity, defining a positive trial if the SAE rate according to CTCAE 5.0 will increase <30% (up to 55%) compared to historical results from TAGS trial (SAE rate 43%). Secondary endpoints were further evaluation of safety and assessment of efficacy according to tumor response and overall and progression‐free survival (OS/PFS). Twenty patients, 20% gastric and 80% GEJ cancers and 55% with ECOG 0 were enrolled. In total, nine SAEs were reported in 25% [95% CI: 8.7‐49.1] of the patients, all without relationship to the systemic therapy. The median OS and PFS were 9.1 months [5.4‐10.1] and 2.9 months [1.7‐4.8], respectively. In addition, a disease control rate of 45% was obtained. The trial showed a favorable safety profile with a numerically lower incidence of SAEs for the combination of ramucirumab with TAS‐102 compared to historical TAGS trial. Furthermore, the combination demonstrated efficacy in the beyond progression setting and therefore warrants further evaluation in a randomized trial compared to TAS‐102 alone. [ABSTRACT FROM AUTHOR]

Background: At present, relatively few lung surgeries are performed without endostaplers. Although there are few staple-related adverse events, severe events must be shared to improve safety. Case presentation: A 74-year-old male suddenly collapsed and was transferred to the Emergency Rescue department. He had shock vitals and contrast-enhanced CT revealed extensive right hemothorax with contrast leakage. He lost consciousness and tension massive hemothorax was suspected. We performed emergency thoracotomy at two sites and were able to achieve hemostasis and save the patient. Upon examining the patient's medical history after his condition stabilized, it was revealed that he was a lung cancer patient who was taking ramucirumab and cilostazol. In addition, the CT scan taken one month before onset revealed the bleeding site of the fifth intercostal artery were almost contact with the staple line from a prior right spontaneous pneumothorax surgery that was performed 11 years previously, which was seemed to damage the intercostal artery. Conclusion: Despite the difficulty in achieving hemostasis due to drug administration history, we successfully treated a case of remote period massive hemothorax attributed to staples, thereby saving the patient. When using drugs that increase the risk of bleeding events, it may be important to consider the position of the staple line while assessing the risk. In the emergent or ICU setting, if the initial incision is not effective, the placement of a new second incision may be valuable. [ABSTRACT FROM AUTHOR]

Objective image studies. We disclosed the presentation and risk factors of TE and evaluated its influence on outcome.Results: A total of 427 patients were included. TE occurred in 43 patients (10.1%). Deep vein thrombosis (DVT) was the most common TE (n = 20). Up to 46.2% of DVT did not occur in the typical lower extremities. Two patients died of TE. Among patients with continuous use or reuse of antiangiogenetic therapy, 18.2% had recurrent TE events. At the occurrence of TE, 28 patients experienced progressive disease (TE with PD), while tumor status remained stable in another 15 patients (TE without PD). The post-TE survival of patients without and with PD were 8.9 months (95% CI 3.9– 13.9) vs 2.2 months (95% CI 0.1– 4.3), P = 0.012. As compared with patients without TE (31.4 months [95% CI 27.1– 35.7]), TE with PD patients experienced a significantly shorter overall survival (20.1 months [95% CI 15.5– 24.6]), but TE without PD patients had comparable survival time (32.7 months [95% CI 7.4– 28.1]) (P = 0006). The use of hormone analogue and proteinuria predicted the events among TE with PD group (aOR 2.79 [95% CI 1.13=6.92]; P = 0.027) and TE without PD group (aOR 4.30 [95% CI 1.13– 16.42]; P = 0.033), respectively.Conclusion: Owing to the different risk factors and influences on the survival time, TE with and without PD may be two different disease entities.

Current NCCN guidelines for second‐line therapy in recurrent or metastatic esophago‐gastric cancers recommend the use of VEGF inhibitors such as ramucirumab. VEGF inhibitors have been shown to be associated with gastrointestinal perforation in clinical trials and late colorectal anastomotic leaks in a few case reports. Here, we present a case of late esophageal anastomotic leak in a patient receiving ramucirumab. Case information was obtained from our institution's electronic medical records. The patient was found to have T4N1M0, poorly differentiated invasive adenocarcinoma and subsequently received neoadjuvant chemoradiation followed by hybrid Ivor‐Lewis esophagectomy 6 weeks later. He recovered well with no leak or perioperative complications. The patient had disease progression 9 months postoperatively on CT and PET imaging. Sixteen months after surgery he began paclitaxel and ramucirumab and 16 weeks after ramucirumab initiation, he was found to have an esophago‐pulmonary fistula in the region of the anastomosis. Biopsies were negative for recurrence at the anastomosis. He died one week later from progressive pneumonia despite stenting. In conclusion, this is the only known report of delayed esophageal anastomotic complication associated with ramucirumab. VEGF inhibitor therapies such as bevacizumab have been associated with late (greater than 3 months postoperative) colorectal anastomotic complications including fistulas and leaks. Risk factors that have been associated are perioperative radiotherapy and history of early postoperative leak. These findings raise concern whether VEGF inhibitor therapy should be used in post‐esophagectomy patients with recurrence if these rare but catastrophic events are likely to be terminal.

Purpose: Vascular endothelial growth factor (VEGF) inhibitors are widely used in chemotherapy for non-small lung cancer (NSCLC). The purpose of the current study was to examine the impact of background cardiovascular risk factors on VEGF inhibitor-related adverse vascular events (VEGF-related AVEs) in patients with NSCLC who also had comorbidities. Methods: We conducted a retrospective study of 118 NSCLC patients treated with bevacizumab or ramucirumab from April 2010 to December 2022. We compared baseline cardiovascular risk factors with VEGF-related AVEs. Results: VEGF-related AVEs and discontinuation due to VEGF-related AVEs were reported in 54 patients and 21 patients, respectively. VEGF-related AVEs were significantly more common with male sex, smoking history, history of hypertension, dyslipidemia, diabetes mellitus, or cardiovascular disease. Discontinuation due to VEGF-related AVEs was significantly more common in patients with history of hypertension or chronic kidney disease. VEGF-related AVEs were significantly more common in patients with ≥ 3 cardiovascular risk factors than patients with < 3. Discontinuation due to VEGF-related AVEs was significantly more common in patients with ≥ 4 cardiovascular risk factors than patients with < 4. Multivariate analysis demonstrated that male sex, hypertension, and ≥ 6 cycles of VEGF inhibitors were each associated with VEGF-related AVEs and hypertension was associated with discontinuation due to VEGF-related AVEs. Conclusion: Our study demonstrated that history of hypertension was independently associated with increased risk of both VEGF-related AVEs and discontinuation due to VEGF-related AVEs. In conclusion, we need to be aware of VEGF-related AVEs when using VEGF inhibitors for patients with ≥ 3 cardiovascular risk factors. [ABSTRACT FROM AUTHOR]

Purpose: Considerable amounts of injected immunoglobulin G-based therapeutic monoclonal antibodies, such as ramucirumab, are distributed into ascites. This study aimed to examine the effect of massive ascites on ramucirumab pharmacokinetics in patients with gastrointestinal cancers. Methods: Population pharmacokinetic analysis of ramucirumab was performed using data on serum ramucirumab concentrations of 52 patients with gastrointestinal cancers, including 8 patients with massive ascites. The Bayesian method using the final population pharmacokinetic model was utilized to estimate trough ramucirumab concentrations after the first dose and at steady state. Results: Population pharmacokinetic analysis revealed that massive ascites as well as body weight were influencing factors for ramucirumab clearance. The estimated ramucirumab clearance was significantly higher in patients with massive ascites than in those with no/mild ascites (0.020 ± 0.004 versus 0.013 ± 0.004 L/h, P < 0.001). The estimated trough ramucirumab concentrations were significantly lower in patients with massive ascites than in those with no/mild ascites after the first dose (26.4 ± 6.8 versus 36.1 ± 7.1 μg/mL, P < 0.001) and at steady state (41.4 ± 16.3 versus 65.9 ± 18.0 μg/mL, P < 0.001). Conclusion: In the present study, the presence of massive ascites affected the pharmacokinetics of ramucirumab in patients with gastrointestinal cancers. Our results suggest that dose optimization of ramucirumab may be necessary in patients with massive ascites due to higher ramucirumab clearance. [ABSTRACT FROM AUTHOR]

Introduction: In the REVEL trial, ramucirumab plus docetaxel demonstrated significant improvements in overall survival (OS), progression-free survival (PFS), and overall response rate (ORR) compared with placebo plus docetaxel for treatment of metastatic non-small cell lung cancer (NSCLC) that progressed during or after platinum-based chemotherapy. Since the approval of ramucirumab plus docetaxel, immune checkpoint inhibitors (ICIs), either as single agents or in combination with chemotherapy, have become the standard of care for first-line treatment of patients with advanced NSCLC. However, efficacy and safety data for ramucirumab plus docetaxel after prior ICI treatment from randomized controlled clinical studies are lacking. Methods: Following Preferred Reporting Items for Systematic Reviews and Meta- Analyses guidelines, a systematic literature review was performed. Electronic databases and select international oncology conference proceedings were searched. Studies published between 01 January 2014 and 01 July 2022, which evaluated 2 efficacy outcomes (and included at least 1 time-to-event endpoint) or safety outcomes of ramucirumab plus docetaxel in NSCLC that progressed after prior ICI treatment, were identified. Twelve studies were included in the analysis. Two treatment groups were selected: ramucirumab plus docetaxel after prior ICI ± chemotherapy (RAM + DTX ICI pre-treated) and ramucirumab plus docetaxel after prior chemotherapy only (RAM + DTX ICI naïve). OS, PFS, ORR, disease control rate (DCR), and safety data were extracted and descriptively summarized across both treatment groups. Results: The pooled weighted median PFS and median OS were 5.7 months (95% confidence interval [CI]: 3.9-6.8) and 11.2 months (95% CI: 7.5-17.5), respectively, in the RAM + DTX ICI pre-treated group and 3.8 months (95% CI: 2.3-4.1) and 13.5 months (95% CI: 8-24.0), respectively, in the RAM + DTX ICI naïve group. The ORR and DCR ranged from 20.9% to 60.0% and from 62.4% to 90.0%, respectively, in the RAM + DTX ICI pre-treated group and from 17.7% to 20.0% and from 57.1% to 75.0%, respectively, in the RAM + DTX ICI naïve group. The safety profile across studies was consistent between both treatment groups, and no new safety signals were reported. Conclusions: Cumulatively, these results support the combination of ramucirumab plus docetaxel as an effective and safe subsequent therapy for the treatment of patients with metastatic NSCLC with disease progression irrespective of previous ICI treatment.

Background: Gastric cancer (GC) is one of the leading causes of cancer-related death worldwide. The first-line treatment for GC is a combination of platinum and fluoropyrimidine-based therapy. Based on the positive results of RAINBOW and REGARD trials, ramucirumab either alone or in combination with paclitaxel has proved to be a safe and active option for second-line treatment in GC patients. Material and methods: Advanced GC patients who received a 28-day cycles of ramucirumab and paclitaxel until disease progression or unacceptable toxicity were evaluated. Eligible patients had ECOG PS ≤ 1 and adequate organ function. Baseline characteristics were assessed for progression-free survival (PFS) and overall survival (OS). The Kaplan–Meier method and Cox proportional-hazards regression models were used for survival analyses. Results: In our single institution experience, we included a total of 67 patients. A median OS of 8 months and a median PFS of 4 months, were recorded. In patients experiencing an initial partial response (PR), we observed a significant association between tumor response and survival outcomes (OS and PFS). The OS and PFS were 15 and 11 months in patients who experienced PR compared to 8 and 4 months in patients without PR (p = 0.02; p = 0.04). Conclusion: Treatment with ramucirumab plus paclitaxel yielded the highest overall response rate reported to date for patients with previously treated advanced GC. In our experience, the initial tumor response is associated with a greater survival benefit which could be further improved by the identification of biomarkers predicting response.

Background: Trifluridine/tipiracil (FTD/TPI) prolongs survival in the third- or later-line treatment for advanced gastric cancer (GC), esophagogastric junction (EGJ) adenocarcinoma, and colorectal cancer. While single-arm phase II trials showed promising outcomes of FTD/TPI plus ramucirumab (RAM) as third- or later-line treatments for advanced GC or EGJ cancer, there have been no clinical trials to directly compare FTD/TPI plus RAM with FTD/TPI monotherapy. Therefore, we have started a randomised phase II trial to evaluate the efficacy and safety of FTD/TPI plus RAM compared with FTD/TPI monotherapy as third- or later-line treatments in patients with advanced GC and EGJ adenocarcinoma. Methods: This RETREVE trial (WJOG15822G) is a prospective, open-label, randomised, multicentre phase II trial comparing FTD/TPI plus RAM versus FTD/TPI monotherapy in a third- or later-line setting. Eligibility criteria include age of > 20 years; performance status of 0 or 1; unresectable or recurrent gastric or EGJ adenocarcinoma; confirmed HER2 status; refractory or intolerant to fluoropyrimidine, taxane or irinotecan; refractory to RAM (not intolerant); and at least a measurable lesion per RECIST 1.1. FTD/TPI (35 mg/m2 twice daily, evening of day 1 to morning of day 6 and evening of day 8 to morning of day 13) was administered orally every 4 weeks, and RAM (8 mg/kg) was administered intravenously every 2 weeks. The primary endpoint is progression-free survival (PFS), and the secondary endpoints are overall survival, objective response rate, disease control rate, and safety. The expected hazard ratio of PFS is set as 0.7, assuming 4-month PFS rate of 27% in FTD/TPI monotherapy and 40% in FTD/TPI plus RAM. The number of subjects was 110, with a one-sided alpha error of 0.10 and power of 0.70. Discussion: This study will clarify the additional effect of RAM continuation beyond disease progression on FTD/TPI in the third- or later-line setting for patients with advanced GC or EGJ cancer.

Background: The association between prior bevacizumab (BEV) therapy and ramucirumab (RAM)-induced proteinuria is not known. We aimed to investigate this association in patients with metastatic colorectal cancer (mCRC). Methods: mCRC patients who received folinic acid, fluorouracil, and irinotecan (FOLFIRI) plus RAM were divided into with and without prior BEV treatment groups. The cumulative incidence of grade 2–3 proteinuria and rate of RAM discontinuation within 6 months (6M) after RAM initiation were compared between the two groups. Results: We evaluated 245 patients. In the Fine-Gray subdistribution hazard model including prior BEV, age, sex, comorbidities, eGFR, proteinuria ≥ 2 + at baseline, and later line of RAM, prior BEV treatment contributed to proteinuria onset (P < 0.01). A shorter interval between final BEV and initial RAM increased the proteinuria risk; the adjusted odds ratios (95% confidence intervals) for the intervals of < 28 days, 28–55 days, and > 55 days (referring to prior BEV absence) were 2.60 (1.23–5.51), 1.51 (1.01–2.27), and 1.04 (0.76–1.44), respectively. The rate of RAM discontinuation for ≤ 6M due to anti-VEGF toxicities was significantly higher in the prior BEV treatment group compared with that in the no prior BEV treatment group (18% vs. 6%, P = 0.02). Second-line RAM discontinuation for ≤ 6M without progression resulted in shorter overall survival of 132 patients with prior BEV treatment (P < 0.01). Conclusion: Sequential FOLFIRI plus RAM after BEV failure, especially within 55 days, may exacerbate proteinuria. Its escalated anti-VEGF toxicity may negatively impact the overall survival.

Chemotherapy plus antiangiogenic agents, including bevacizumab, ramucirumab and aflibercept, is a standard second-line treatment for patients with metastatic colorectal cancer, but which specific agents should be selected is ambiguous due to a lack of clear evidence from prospective studies. Previous reports have suggested ramucirumab and aflibercept could be more effective than bevacizumab in patients with high VEGF-D and high VEGF-A, respectively. JCOG2004 is a three-arm, randomized, phase II study to identify predictive biomarkers for these agents in patients who have failed first-line treatment. The study will enroll 345 patients from 52 institutions for 2 years, with progression-free survival in high VEGF-D (bevacizumab vs ramucirumab) and high VEGF-A (bevacizumab vs aflibercept) serving as the primary end point. Clinical Trial Registration:jRCTs031220058 (www.jrct.niph.go.jp) A multi-institutional randomized phase II study to identify predictive biomarkers for antiangiogenic agents with FOLFIRI in second-line treatment of patients with metastatic colorectal cancer was started in May 2022.

Background: According to the 2023 guidelines for treating non-small-cell lung cancer (NSCLC), first-line treatment and recently developed agents for the treatment of epidermal growth factor (EGFR) mutation-positive locally advanced or metastatic NSCLC were compared in this meta-analysis. Treatment regimens involved in the included studies included first, second, and third-generation tyrosine kinase inhibitors (TKIs), TKIs plus chemotherapy, TKIs plus angiogenesis inhibitors, and platinum-containing doublet chemotherapy with or without bevacizumab. Considering the varying efficacy and safety of drugs in people of different ethnic origins, the optimal regimen should be determined, and the safety of first-line treatments should be assessed in the Asian population specifically. Methods: PubMed, Embase, the Cochrane Library, Web of Science, and the China National Knowledge Infrastructure (CNKI) were systematically searched to retrieve reports on randomized controlled trials (RCTs) with research data published from inception to 1 February 2023. Adopting Asian patient populations as the target (including studies in which Asian patients accounted for more than 50% of the sample), a network meta-analysis (NMA) was conducted for comparison of treatment regimens and treatments were ranked based on the surface under the cumulative ranking curve (SUCRA). Results: A total of 19 RCTs involving 5,824 patients and covering 14 treatment regimens were included. The primary outcome measure examined in this study was progression-free survival (PFS); other outcome measures examined were overall survival (OS), disease control rate (DCR), objective response rate (ORR), occurrence of any adverse events (AE), occurrence of adverse events of grade 3 or above (=3AE), and occurrence of serious adverse events (SAE). In terms of PFS, all regimens including TKIs (as a monotherapy or in combination with other therapies), as well as bevacizumab (Bev) plus chemotherapy (Ch) were found to be significantly superior to basic chemotherapy (HRs: 0.09-0.61, p < 0.05 in all cases compared with Ch alone). The highest-ranking therapies were erlotinib (Erl) plus Bev (SUCRA: 0.94) and Erl plus ramucirumab (Ram) (SUCRA: 0.93). Regarding OS, no significant differences was observed between first-line treatment strategies; the top four treatments based on SUCRA, in rank order, were Bev + Ch (0.87), gefitinib (Gef) plus Ch (0.81), dacomitinib (Dac) (0.79), and osimertinib (Osi) (0.69). Additionally, there were no significant differences between first-line treatment strategies in terms of DCR. Regarding ORR, the top three treatments based on SUCRA were Erl + Bev (0.85), Erl + Ram (0.76), and Gef + Ch (0.74). No significant difference between first-line treatment strategies was observed in terms of the risk of AE. However, based on SUCRA, Erl ranked highest on avoidance of = 3AE (0.97), and Osi ranked highest on avoidance of SAE (0.91). Conclusion: Based on these analyses of survival benefits, tumor burden response, and safety, furmonertinib (Fur), Osi, and aumolertinib (Aum) may represent the best treatment regimen options for Asian patients, significantly prolonging survival (as measured by median PFS/OS), eliciting a greater tumor burden response, and exposing patients to a lower risk of adverse events. Although Erl + Bev and Erl + Ram are associated with the best survival benefits in terms of PFS, further clinical studies are still needed to identify ways to reduce the risk of adverse events.

Purpose: The aim of this study was to investigate the factors predictive of clinical outcome in advanced hepatocellular carcinoma patients receiving ramucirumab treatment. Methods: We conducted a retrospective study using a multi‐institutional electronic medical records database in Taiwan. We included advanced HCC patients newly receiving ramucirumab as second‐line or beyond systemic therapy between January 2016 and February 2022. The clinical outcomes were median progression‐free survival (PFS) based on the modified Response Evaluation Criteria in Solid Tumors (mRECIST), overall survival (OS) and adverse events. We applied Kaplan–Meier methods to estimate median PFS and OS. Uni‐variable and multi‐variable Cox regression models were applied to identify the prognostic factors. Results: We included 39 ramucirumab naive users with a median age of 65.5 (IQR: 57.0–71.0) years and treatment time of 5.0 (3.0–7.0) cycles, of whom 82.1% were male and 84.6% were Barcelona Clinic Liver Cancer (BCLC) stage C. After median follow‐up time of 6.0 months, 33.3% of patients' AFP level had decreased more than 20% within 12 weeks. The median PFS and OS were 4.1 months and non‐reach, respectively. Moreover, tumor burden beyond the up‐to‐11 criteria (HR: 2.95, 95% CI: 1.04–8.38) and a decrease in estimated glomerular filtration rate of more than 10% within 12 weeks (HR: 0.31, 0.11–0.88) were significantly related to PFS in the multi‐variable analysis. No patient discontinued ramucirumab during the treatment on account of side effects. Conclusion: Ramucirumab was an effective treatment option with good AFP response for advanced HCC patients in real‐world experience. Tumor burden beyond the up‐to‐11 criteria and a decrease in estimated glomerular filtration rate were independent predictive factors for progression‐free survival. [ABSTRACT FROM AUTHOR]

This multicenter, randomized phase II/III study evaluated the addition of the vascular endothelial growth factor receptor‐2 inhibitor ramucirumab to FLOT as perioperative treatment for resectable esophagogastric adenocarcinoma. Patients received either FLOT alone (Arm A) or combined with ramucirumab followed by ramucirumab monotherapy (Arm B). The primary endpoint for the phase II portion was the pathological complete or subtotal response (pCR/pSR) rate. Baseline characteristics were comparable between both arms with a high rate of tumors signet‐ring cell component (A:47% B:43%). No between‐arm difference in pCR/pSR rate was seen (A:29% B:26%), therefore the transition to phase III was not pursued. Nevertheless, the combination was associated with a significantly increased R0‐resection rate compared with FLOT alone (A:82% B:96%; P =.009). In addition, the median disease‐free survival was numerically improved in Arm B (A:21 months B:32 months, HR 0.75, P = 0.218), while the median overall survival was similar in both treatment arms (A:45 months B:46 months, HR 0.94, P = 0.803). Patients with Siewert type I tumors receiving transthoracic esophagectomy with intrathoracic anastomosis showed an increased risk of serious postoperative complications after ramucirumab treatment, therefore recruitment of those patients was stopped after the first‐third of the study. Overall, surgical morbidity and mortality was comparable, whereas more non‐surgical grade ≥ 3 adverse events were observed with the combination, especially anorexia (A:1% B:11%), hypertension (A:4% B:13%) and infections (A:19% B:33%). The combination of ramucirumab and FLOT as perioperative treatment shows efficacy signals, particularly in terms of R0 resection rates, for a study population with a high proportion of prognostically poor histological subtypes, and further evaluation in this subgroup seems warranted.

Purpose: This study aimed to compare ramucirumab-paclitaxel versus chemotherapy in second-line (2L) advanced gastroesophageal cancer (aGEC) based on HER2 status and analyze prognostic factors. Methods: The study includes patients from the AGAMENON-SEOM registry with aGEC and known HER2 status who received 2L between 2016 and 2021. The Kaplan–Meier method was used to calculate progression-free survival (PFS) and overall survival (OS) and multivariable Cox regression analysis was done to adjust for confounding variables. Results: Of the 552 patients who met the selection criteria, 149 (26.9%) had HER2-positive aGEC, 89 were treated with chemotherapy, and 60 with ramucirumab-paclitaxel, and 403 had an HER2-negative aGEC, 259 were treated with chemotherapy, and 144 with ramucirumab-paclitaxel. In the whole sample, 2L PFS was 3.0 months (95% CI 2.8–3.2), 2L OS, 5.7 months (5.2–6.3), and ramucirumab-paclitaxel versus chemotherapy was associated with increased PFS (HR 0.64, 95% CI 0.53–0.78, p < 0.0001) and OS (HR 0.68, 0.55–0.83, p = 0.0002). Median PFS of ramucirumab- paclitaxel versus chemotherapy was 3.5 vs 2.8 months (HR 0.67, 0.54–0.83, p = 0.0004) in HER2-negative, and 4.7 vs 2.7 months (HR 0.57, 0.40–0.82, p = 0.0031) in HER2-positive aGEC, respectively. Median OS for ramucirumab-paclitaxel versus chemotherapy was 6.6 vs 5 months (HR 0.67, 0.53–0.85, p = 0.0007) in HER2-negative, and 7.4 vs 5.6 months (HR 0.70, 0.53–1.04, p = 0.083) in HER2-positive aGEC, respectively. ECOG-PS, tumor burden, Lauren subtype, and neutrophil–lymphocyte ratio were prognostic factors. Conclusions: In patients with an aGEC from the AGAMENON-SEOM registry, 2L treatment with ramucirumab-paclitaxel was superior to chemotherapy in PFS, OS and response rate, independent of HER2 status.

Background: Paclitaxel in combination with ramucirumab is the standard of care second-line therapy in gastro-esophageal adenocarcinoma (GEA). As the number of taxane pretreated patients in the perioperative or first-line setting is increasing, it is unknown whether these patients benefit from re-applying a taxane in using the combination of paclitaxel and ramucirumab. Furthermore, the rates of neurotoxicity with first-line FOLFOX or FLOT range from 30%–70%, making second-line taxane‐containing therapy less suitable to a meaningful portion of patients. This patient group is likely to benefit from a taxane-free second-line chemotherapy regimen, such as FOLFIRI and ramucirumab (FOLFIRI-Ram). Therefore, the RAMIRIS phase III trial evaluates the effects of the regimen of FOLFIRI-Ram in the second-line treatment after a taxane-based chemotherapy in patients with advanced GEA. Methods: The RAMIRIS trial is a randomized, open-label, multicenter phase II/III study comparing treatment of FOLFIRI-Ram (arm A) with paclitaxel and ramucirumab (arm B). The Phase II is already closed with 111 enrolled patients. In the phase III, 318 taxane-pretreated patients with advanced GEA will be recruited and randomized 1:1 to FOLFIRI (5-FU 2400 mg/m2 over 46 h i.v., irinotecan 180 mg/m2 i.v.; 5-FU 400 mg/m2 bolus; leucovorin 400 mg/m2 i.v.; on day 1 and 15, q28) with ramucirumab 8 mg/kg every two weeks (Arm A) or paclitaxel 80 mg/m2 (days 1, 8, 15, q28) with ramucirumab 8 mg/kg every two weeks (Arm B). The primary endpoints are overall survival (OS) and objective overall response rate (ORR). Secondary endpoints are progression-free survival (PFS), disease control rate and safety and quality of life as assessed by EORTC-QLQ-C30 questionnaire. Discussion: The already completed RAMIRIS phase II demonstrated feasibility and efficacy of FOLFIRI-Ram. Especially docetaxel-pretreated patients seemed to markedly benefit from FOLFIRI-Ram, with favorable response- and PFS rates and lower toxicity. This offers a rationale for the phase III trial. If the RAMIRIS III trial transfers and confirms the results, they will affect the current treatment guidelines, recommending the combination therapy of FOLFIRI-Ram for taxane-pretreated patients with advanced GEA.

Aim: To describe real-world treatment sequences of ramucirumab relative to immune checkpoint inhibitors (ICIs) in patients with advanced gastroesophageal cancer. Methods: Retrospective, observational study including adult patients treated with ramucirumab (April 2014–June 2020) from a nationwide health-record database. Results: In 1117 eligible patients, ramucirumab + paclitaxel was the most common ramucirumab-containing regimen (72.0%). A total of 217 patients also received an ICI. For ramucirumab then ICI (n = 148) and ICI then ramucirumab (n = 50), ramucirumab + taxane and ICI monotherapy were the most frequent approaches, most commonly observed as second- and third-line (2L and 3L). Median time on ramucirumab in 2L and 3L was similar regardless of sequence with ICI. Conclusion: Most patients with advanced gastroesophageal cancer received ramucirumab before ICI, with ramucirumab + paclitaxel as the most common ramucirumab-based regimen. What is the Order of New Treatments for Gastroesophageal Cancers in the Real World? Gastroesophageal cancers (cancers of the stomach or food pipe) which cannot be cured are first treated using traditional chemotherapy. Newer anti-cancer therapies with fewer side effects, such as ramucirumab (RAM) and immune checkpoint inhibitors (ICI), are now available either alone or in combination with chemotherapy. We designed this study to describe the order of use for RAM and ICI. The patients in this study were from Flatiron Health database, which includes electronic medical record data of US patients with gastroesophageal cancers. The included patients had been treated with RAM and were grouped based on the treatments received and in the order in which they received RAM and ICI. Of the patients who received both RAM and ICI, RAM then ICI was the most common order, followed by ICI then RAM and then RAM plus ICI at the same time. RAM in combination with paclitaxel (a chemotherapy) was the most common RAM-containing treatment. The duration of RAM therapy was the same whether patients received the treatment before or after ICI. These findings can be used by patients with gastroesophageal cancers and oncologists when making treatment decisions, specifically if RAM might be an option when it is time to change treatments. Real-world studies like this help answer questions that were not addressed in clinical trials. [ABSTRACT FROM AUTHOR]

Background: Recent reports suggested combining ramucirumab with epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) to overcome EGFR resistance in non–small cell lung cancer (NSCLC). Nonetheless, evidence supporting the activity of afatinib and ramucirumab is lacking. This study investigated the survival benefits and safety profile of afatinib plus ramucirumab in patients with treatment-naïve, EGFR-mutated, metastatic NSCLC. Materials and methods: The medical records of patients with EGFR-mutated NSCLC were retrospectively retrieved. Patients who received first-line sequential afatinib followed by ramucirumab and the first-line combination of afatinib plus ramucirumab were included. The Kaplan-Meier was used to estimate the progression-free survival (PFS) of all included patients, patients on sequential afatinib followed by ramucirumab (PFS1), and patients on the up-front combination of afatinib and ramucirumab (PFS2). Results: Thirty-three patients were included (25 women; median age: 63 [45–82] years). The median follow-up of the included patients was 17 months (range 6–89 months). the median PFS for the whole cohort was 71 months (95% CI 67.2–74.8) with eight events during the follow-up. The median PFS1 and PFS2 were 71 months (95 CI not defined) and 26 months (95% CI 18.6–33.4), respectively. In terms of OS, the median OS for all patients and patients on sequential treatment was not defined, while the median OS for patients on upfront combination was 30 months (95% CI 20.9–39.1). There was no significant association between EGFR mutation type and PFS1 or PFS2. Conclusions: Afatinib plus ramucirumab could improve the PFS of patients with EGFR-positive NSCLC at a predictable safety profile. Our data also suggest a survival benefit of adding ramucirumab to afatinib in patients with uncommon mutations, which should be investigated further. [ABSTRACT FROM AUTHOR]

Objectives: Ramucirumab (RAM) and docetaxel (DOC) are commonly used after first-line therapy for advanced non-small cell lung cancer (NSCLC). Therefore, we aimed to elucidate sequencing strategies of RAM and DOC following prior treatments, including immune checkpoint inhibitor (ICI), cytotoxic agent (CTx) alone, bevacizumab (BEV), and tyrosine kinase inhibitor (TKI). Methods: We recruited patients with NSCLC who received RAM and DOC and compared the groups with and without prior ICI, CTx alone, BEV, and TKI, respectively. By tumor response to such treatments, the patients were further classified into "complete response (CR) + partial response (PR)," "stable disease," and "progressive disease" groups, respectively. We compared RAM and DOC efficacy among these groups. Results: In total, 237 patients were registered. In the group with prior ICI, the objective response rate and disease control rate were significantly higher than those without prior ICI (p = 0.012 and 0.028, respectively), and the median progression-free survival (PFS) was also significantly longer (p = 0.027). There were no significant differences in PFS between the groups with and without CTx alone, BEV, and TKI. Multivariate analysis revealed that prior ICI was an independent factor associated with better PFS. Furthermore, the prior ICI group with CR + PR significantly prolonged PFS compared to the group without prior ICI (p = 0.013). Conclusion: RAM and DOC may be preferably administered after ICI, rather than after CTx alone, BEV, or TKI, and, furthermore, enhanced if the prior ICI has a favorable tumor response.

Purpose: Liver metastasis (LM) is reported in approximately 40% of patients with advanced/ metastatic gastric/gastroesophageal junction adenocarcinoma (metastatic esophagogastric adenocarcinoma; mGEA) and is associated with a worse prognosis. This post-hoc analysis from the RAINBOW trial reported the efficacy, safety, and biomarker outcomes of ramucirumab and paclitaxel combination treatment (RAM+PAC) in patients with (LM+) and without (LM−) LM at baseline. Materials and Methods: Patients (n=665) were randomly assigned on a 1:1 basis to receive either RAM+PAC (LM+: 150, LM−: 180) or placebo and paclitaxel (PL+PAC) (LM+: 138, LM−: 197). The overall survival (OS) and progression-free survival (PFS) were evaluated using stratified Kaplan–Meier and Cox regression models. The correlation of dichotomized biomarkers (VEGF-C, D; VEGFR-1,2) with efficacy in the LM+ versus LM− subgroups was analyzed using the Cox regression model with reported interaction P-values. Results: The presence of LM was associated with earlier progression than those without LM, particularly in patients receiving PL+PAC (hazard ratio [HR], 1.68). RAM+PAC treatment improved OS and PFS irrespective of LM status but showed greater improvement in LM+ than that in LM− (OS HR, 0.71 [LM+] vs. 0.88 [LM−]; PFS HR, 0.47 [LM+] vs. 0.76 [LM−]). Treatment-emergent adverse events were similar between patients with and without LM. No predictive relationship was observed between biomarker levels (VEGF-C, D; VEGFR-1,2) and efficacy outcome (OS, PFS) (all interaction P-values >0.05). Conclusions: RAM provided a significant benefit, irrespective of LM status; however, its effect was numerically stronger in patients with LM. Therefore, RAM+PAC is a clinically meaningful therapeutic option for patients with mGEA and LM. [ABSTRACT FROM AUTHOR]

Current first-line standard therapy for metastatic non-small cell lung cancer without driver mutations involves chemotherapy and immunotherapy combination. Prior to the advent of immune checkpoint inhibition, REVEL, a randomized phase III trial demonstrated improved progression-free and overall survival with ramucirumab and docetaxel (ram+doc) in patients who failed platinum-based first-line therapy. Long-term outcomes related to second-line ramucirumab and docetaxel after first-line immunotherapy exposure remain unknown. We analyzed outcomes for 35 patients from our center whom received ramucirumab and docetaxel following disease progression on chemotherapy and immunotherapy combination. Median progression-free survival among patients who received ram+doc after exposure to immunotherapy was 6.6 months (95% CI = 5.5 to 14.9 months; p<0.0001), and median overall survival was 20.9 months (95% CI = 13.4 months to infinity; p<0.0001). These outcomes suggest that there may a synergistic benefit to combining chemotherapy with anti-angiogenic therapy after immunotherapy exposure. Future analyses should be evaluated prospectively and among a larger patient subset. [ABSTRACT FROM AUTHOR]

Purpose: Ramucirumab was shown to be effective as a second-line treatment after sorafenib in patients with advanced hepatocellular carcinoma (HCC) with alpha-fetoprotein levels > 400 ng/mL in a worldwide phase 3 trial. Ramucirumab is used in patients pretreated with various systemic therapies in clinical practice. We retrospectively examined the treatment outcomes of ramucirumab administered to advanced HCC patients after diverse systemic therapies. Methods: Data were collected from patients with advanced HCC who received ramucirumab at three institutions in Japan. Radiological assessments were determined according to both Response Evaluation Criteria in Solid Tumours (RECIST) version 1.1 and modified RECIST and the Common Terminology Criteria for Adverse Events version 5.0 was used to assess adverse events. Results: A total of 37 patients treated with ramucirumab between June 2019 and March 2021 were included in the study. Ramucirumab was administered as second, third, fourth, and fifth-line treatment in 13 (35.1%), 14 (37.8%), eight (21.6%), and two (5.4%) patients, respectively. Most patients (29.7%) who received ramucirumab as a second-line therapy were pretreated with lenvatinib. We found grade 3 or higher adverse events only in seven patients and no significant changes in the albumin-bilirubin score during ramucirumab treatment in the present cohort. The median progression-free survival of patients treated with ramucirumab was 2.7 months (95% confidence interval, 1.6–7.3). Conclusion: Although ramucirumab is used for various lines of treatment other than second-line immediately after sorafenib, its safety and effectiveness were not significantly different from the findings of the REACH-2 trial.

Background/Aim: The antineoplastic drug docetaxel (DOC) and the antivascular endothelial growth factor inhibitor ramucirumab (RAM) are widely used in combination for second or later-line regimens for advanced non-small cell lung cancer (NSCLC). While the median progression-free survival (PFS) of DOC+RAM has been reported to be less than six months in both clinical trials and clinical practice, there appear to be some patients with longterm PFS. This study aimed to clarify the existence and characteristics of these patients. Patients and Methods: We conducted a retrospective review of patients with advanced NSCLC treated with DOC+RAM between April 2009 and June 2022 at our three hospitals. There was no established definition of long-term PFS, thus in this study, a PFS of 12 months or longer was defined as long-term PFS. Results: During the study period, 91 patients received DOC+RAM treatment. Of these, 14 (15.4%) achieved long-term PFS. There were no significant differences in patient characteristics between patients with PFS ≥12 months and those with PFS <12 months, except for ‘clinical stage IIIAC’ at DOC+RAM initiation and ‘post-surgical recurrence’. In uni- and multivariate analyses, favorable factors for PFS were ‘Stage III at the start of DOC+RAM’ in driver genenegative patients, and ‘under 70 years old’ in driver genepositive patients. Conclusion: Many patients in this study achieved long-term PFS with DOC+RAM treatment. In the future, it is expected that long-term PFS will be defined, and the background of patients who achieve such PFS will become clearer. [ABSTRACT FROM AUTHOR]

Asssociation versus causation, Chemotherapy, Confidence interval, Confounding, Gastroesophageal cancer, Hazard ratio, Prognosis, Ramucirumab, Statistical adjustmen, Weight loss Mansoor and his colleagues wondered whether early weight loss during the first course of chemotherapy for advanced gastric and gastroesophageal junction adenocarcinoma (G/GEA) had particular prognostic information and noted that, if it did, there might be an opportunity to alter the disease course with some type of intervention. Although such patients have worse inflammatory disease than do rheumatoid arthritis patients without anemia, transfusing them does not make the arthritis better. For example, another plausible hypothesis is that more severe disease produces a worse outcome and, along the way, the patient loses more weight; the weight loss is simply an unrelated epiphenomenon that had no effect on the outcome.

Aim: Few studies have reported the efficacy and safety of ramucirumab (RAM) after atezolizumab plus bevacizumab (Atezo/Beva) treatment and the overall associated outcomes. Thus, we aimed to evaluate the therapeutic effects and safety of RAM post‐treatment with Atezo/Beva. Methods: This retrospective study enrolled 46 patients with unresectable hepatocellular carcinoma who were treated with RAM. The patients were classified into the RAM administered following Atezo/Beva failure (n = 12) or RAM administered following other drug failure (n = 34) groups. Progression‐free survival (PFS), overall survival (OS), and adverse event (AE) rates were assessed. Results: There were significant differences in the objective response rates and disease control rates between the RAM administered following Atezo/Beva and RAM administered following others groups (objective response rate 33.3%. vs. 0.0%, p = 0.001; disease control rate 83.3% vs. 32.3, p = 0.001). Although there was no significant difference in the OS rates, the median PFS rates in the RAM administered following Atezo/Beva group was significantly higher than in the RAM administered following others group (PFS 3.9 months. vs. 1.9 months, p = 0.047). The AE rates were comparable between the two groups; ascites was the most common AE (45.6%). Using decision tree analysis, the presence of splenomegaly and body mass index (BMI) < 19.8 were the first and second splitting variables for RAM‐related ascites, respectively. Conclusions: The therapeutic effect of RAM increased in patients with Atezo/Beva failure. Patients with splenomegaly and low BMI should be monitored for ascites during RAM treatment.

Increasing trend for progression-free survival (PFS)-based primary endpoint in oncology has led to lack of mature overall survival (OS) data at the time of approval. To address this evidence gap in economic evaluations, we used a joint Bayesian approach to predict survival outcomes using immature OS data from the RELAY trial. Patient data from RELAY and systematic literature review (SLR) of phase 3 randomized clinical trials with hazard ratio (HR) estimates of mature PFS and immature OS were considered. OS and PFS were analyzed individually using a univariate model; bivariate analysis was performed using a joint model based on modified Bayesian normal induced copula estimation model. First, a Bayesian univariate model incorporated informative priors based on predicted HR and acceleration factor for OS and PFS. Second, a Bayesian-based joint model of RELAY PFS and OS data was based on the correlation between PFS and OS established in trials of similar populations. Marginal distribution of PFS was used to estimate the same for OS. Publications (N = 122) of first-line treatments in patients with epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer were identified in the SLR, of which 36 trials were linked to RELAY. Twenty-six trials with HR data were used. The univariate model could predict OS with reduced uncertainty compared with the frequentist approach. In the joint model, the marginal OS distribution borrowed strength from the marginal PFS distribution through the established correlation coefficient. Bayesian approach was successfully used in RELAY analysis but may not be universally applied to oncology trials due to the different associations of OS and PFS and different trial patient populations. We demonstrated that both the univariate and joint Bayesian models reduced uncertainty in predicting OS compared to frequentist method. The methodology introduced here will have potential applications in clinical decision-making for other oncology trials. [ABSTRACT FROM AUTHOR]

Background: Alpha-Fetoprotein Producing Gastric Cancer (AFPGC) is an aggressive subgroup of gastric cancer. Recently ramucirumab has shown survival benefits in hepatocellular carcinoma, but only in those with higher Alpha-Fetoprotein (AFP) levels. However, the efficacy of ramucirumab-containing chemotherapy in AFPGC remains unclear. Methods: We retrospectively assessed 352 patients who received ramucirumab-containing chemotherapy between June 2015 and December 2019. AFPGC was defined when serum AFP levels were elevated at diagnosis and correlated with the disease state during treatment. Non-AFPGC was defined when serum AFP levels were normal at diagnosis. Results: Among the 352 patients, 28 patients were defined as AFPGC and 246 patients were defined as non-AFPGC. AFPGC was characterized by high frequency of liver metastasis and low frequency of peritoneal metastasis compared to non-AFPGC. Ramucirumab containing chemotherapy showed higher response rates in AFPGC (39.1% vs 24.8%, p = 0.198) and disease control rates (86.9% vs 61.5%, p = 0.028) than those of non-AFPGC, respectively. Median progression-free survival (PFS) was 5.5 months (95%CI 3.9–7.1) in AFPGC and 4.0 months (95%CI 3.6–4.6) in non-AFPGC (HR: 0.91, 95% CI 0.61–1.36, p = 0.66), and median overall survival (OS) was 10.7 months (95% CI 7.4–20.8) in AFPGC and 9.2 months (95% CI 8.1–10.4) in non-AFPGC (HR: 0.72, 95% CI 0.48–1.08, p = 0.11), respectively. In multivariate analysis, AFPGC was not a negative prognostic factor both for PFS and OS. Conclusion: Ramucirumab containing chemotherapy showed higher response and comparable survival in AFPGC compared to those of non-AFPGC. Considering the generally poor prognosis of AFPGC, ramucirumab-containing chemotherapy might be a promising treatment option in AFPGC. [ABSTRACT FROM AUTHOR]

Background Ramucirumab is indicated for patients with advanced hepatocellular carcinoma (HCC) and α-fetoprotein (AFP) ≥400 ng/mL following sorafenib. Here, we prospectively studied ramucirumab following non-sorafenib systemic therapies. Materials and Methods This open-label, non-comparative cohort of REACH-2 enrolled patients with advanced HCC, Child-Pugh class-A liver disease, and AFP ≥400 ng/mL who had received 1-2 lines of therapy, excluding sorafenib or chemotherapy. Ramucirumab was administered 8 mg/kg intravenously Q2W. The primary endpoint was safety. Secondary endpoints were overall survival, progression-free survival, objective response rate (RECIST v1.1), time to progression, pharmacokinetics, and patient-reported outcomes. Final analysis occurred after all enrolled patients completed ≥3 treatment cycles or discontinued treatment. Results Between April 27, 2018, and March 29, 2021, 47 patients were treated at 21 investigative sites in Asia, Europe, and USA. The most frequently reported grade ≥3 adverse events, regardless of causality, were hypertension (11%), proteinuria (6%), hyponatremia (6%), and AST increased (6%). Two patients died from adverse events (myocardial infarction and upper gastrointestinal hemorrhage), deemed related to treatment. Median progression-free survival, time to progression, and overall survival were 1.7 months, 2.8 months, and 8.7 months, respectively. The objective response rate was 10.6% with a median duration response of 8.3 months. Median time to deterioration in FHSI-8 total score was 4.4 months. Conclusion Ramucirumab demonstrated consistent and meaningful clinical activity with no new safety signals following non-sorafenib therapies in patients with advanced HCC and AFP ≥400 ng/mL. This represents one of the first sequencing studies for patients with advanced HCC not treated with sorafenib. [ABSTRACT FROM AUTHOR]
