Objective The randomized phase 3 CORAIL trial evaluated whether lurbinectedin improved progression-free survival (PFS) compared to pegylated liposomal doxorubicin (PLD) or topotecan in patients with platinum-resistant ovarian cancer. Methods Patients were randomly assigned (1:1) to lurbinectedin 3.2 mg/m2 1-h i.v. infusion q3wk (experimental arm), versus PLD 50 mg/m2 1-h i.v. infusion q4wk or topotecan 1.50 mg/m2 30-min i.v. infusion Days 1–5 q3wk (control arm). Stratification factors were PS (0 vs. ≥1), prior PFI (1–3 months vs. >3 months), and prior chemotherapy lines (1–2 vs. 3). The primary endpoint was PFS by Independent Review Committee in all randomized patients. This study was registered with ClinicalTrials.gov , NCT02421588 . Results 442 patients were randomized: 221 in lurbinectedin arm and 221 in control arm (127 PLD and 94 topotecan). With a median follow-up of 25.6 months, median PFS was 3.5 months (95% CI, 2.1–3.7) in the lurbinectedin arm and 3.6 months (95% CI, 2.7–3.8) in the control arm (stratified log-rank p = 0.6294; HR = 1.057). Grade ≥ 3 treatment-related adverse events (AEs) were most frequent in the control arm: 64.8% vs. 47.9% (p = 0.0005), mainly due to hematological toxicities. The most common grade ≥ 3 AEs were: fatigue (7.3% of patients) and nausea (5.9%) with lurbinectedin; mucosal inflammation (8.5%) and fatigue (8.0%) in the control arm. Conclusions The primary endpoint of improvement in PFS was not met. Lurbinectedin showed similar antitumor efficacy and was better tolerated than current standard of care in patients with platinum-resistant ovarian cancer.

ObjectiveSecond-line treatment of endometrial cancer is an unmet medical need. We conducted a phase I study evaluating lurbinectedin and doxorubicin intravenously every 3 weeks in patients with solid tumors. The aim of this study was to characterise the efficacy and safety of lurbinectedin and doxorubicin for patients with endometrial cancer.MethodsThirty-four patients were treated: 15 patients in the escalation phase (doxorubicin 50 mg/m2 and lurbinectedin 3.0–5.0 mg) and 19 patients in the expansion cohort (doxorubicin 40 mg/m2 and lurbinectedin 2.0 mg/m2). All histological subtypes were eligible and patients had received one to two prior lines of chemotherapy for advanced disease. Antitumor activity was evaluated every two cycles according to the Response Evaluation Criteria in Solid Tumors version 1.1. Adverse events were graded according to the National Cancer Institute-Common Terminology Criteria for Adverse Events version 4.ResultsMedian age (range) was 65 (51–78) years. Eastern Cooperative Oncology Group performance status was up to 1 in 97% of patients. In the escalation phase, 4 (26.7%) of 15 patients had confirmed response: two complete and two partial responses (95% CI 7.8% to 55.1%). Median duration of response was 19.5 months. Median progression-free survival was 7.3 (2.5 to 10.1) months. In the expansion cohort, confirmed partial response was reported in 8 (42.1%) of 19 patients (95% CI 20.3% to 66.5%). Median duration of response was 7.5 (6.4 to not reached) months, median progression-free survival was 7.7 (2.0 to 16.7) months and median overall survival was 14.2 (4.5 to not reached) months. Fatigue (26.3% of patients), and transient and reversible myelosuppression (neutropenia, 78.9%; febrile neutropenia, 21.1%; thrombocytopenia, 15.8%) were the main grade 3 and higher toxicities in the expanded cohort.ConclusionsIn patients with recurrent advanced endometrial cancer treated with doxorubicin and lurbinectedin, response rates (42%) and duration of response (7.5 months) were favorable. Further evaluation of doxorubicin and lurbinectedin is warranted in this patient population.

Lurbinectedin is a marine-derived drug that inhibits transcription, a process that is frequently dysregulated in small cell lung cancer. The activity of lurbinectedin has been studied in many solid tumors, showing not only promising results but also a favorable safety profile. In relapsed small cell lung cancer, the drug has shown encouraging activity both as a single agent and in combination with doxorubicin, paclitaxel or irinotecan. The USA FDA has recently granted accelerated approval to lurbinectedin monotherapy in this setting. This article provides an update on available data and ongoing studies of lurbinectedin in small cell lung cancer, including Phase I combination trials, the basket Phase II trial and the ATLANTIS Phase III trial.Lay abstract Lung cancer is currently responsible for a large number of cancer deaths worldwide. Small cell lung cancer (SCLC) is considered the most aggressive subtype of lung cancer. When a patient presents with extensive SCLC, first-line treatment needs to be used. The most appropriate treatment option for the patient is selected; however, it is possible for the cancer to continue to get worse, even over a brief period of time. The patient will then be given another treatment; however, studies on the effectiveness of classical second-line drugs are scarce. For this reason, new therapies for SCLC are in development. One of these treatments is a marine-derived drug called lurbinectedin, which shows promising activity in some solid tumors, such as extensive SCLC, after failure of first-line treatment. Here the authors present the results of the main trials related to the activity of lurbinectedin either alone or in combination with other drugs for this type of cancer.

McArdle disease, also known as glycogen storage disease type V, is an autosomal recessive disease due to the absence of myophosphorylase activity, leading to the complete disruption of glycogen breakdown in muscles. We present a rare case of a Caucasian male, aged 26 years, who developed rhabdomyolysis-induced acute renal failure and uremic encephalopathy. Neurological examination and histopathological studies supported the diagnosis of McArdle disease. The severity of his symptoms necessitated urgent hemodialysis, upon which the patient reported improvement in status. Acute renal failure in McArdle disease usually resolves with supportive treatment and maintenance of regular physical activity. Nevertheless, in more severe cases, intensive care with urgent hemodialysis may be needed. A multidisciplinary approach is necessary for the adequate management of similar cases.

Helicobacter pylori, a human pathogen that colonizes the stomach of 50% of the world's population, is associated with gastritis, gastric adenocarcinoma, and mucosa-associated lymphoid tissue (MALT) lymphoma. Diseases are characterized by severe inflammatory responses in the stomach that are induced by various chemokines and cytokines. Recently, oncostatin M (OSM), an IL-6 family cytokine, was detected in early gastric cancer biopsies. In this study, we showed that Helicobacter pylori induced secretion of OSM and overexpression of its type II receptor OSMRβ (OSM/OSMRβ) in a human gastric adenocarcinoma cell line (AGS) over 24 h of infection. Furthermore, we showed that the induction of OSM and OSMRβ was carried out by heat-sensitive Helicobacter pylori outer membrane vesicle (OMV) protein. Collectively, our results established, for the first time, a direct relation between Helicobacter pylori OMVs and the OSM/OSMRβ signaling axis.

Background: Verbal and non-verbal communications are an inherent component of physician-patient interactions. The psychological and physiological benefits of non-verbal communication such as gestures, expressions, eye contact, and particularly physical touch in healthcare have been previously explored by the scientific community, albeit insufficiently in the primary care context. Objective: This study aims to address this gap by investigating physician and patient perceptions of expressive touch and its effect on patient satisfaction in primary care consultations in Lebanon. Methods: We recruited 12 physicians and 13 patients and subjected them to audiotaped semi-structured interviews. We selected the patients from three hospitals, while physician responders were from the Faculty of Medical Sciences of the Lebanese University. We translated the survey instrument into Arabic and validated it using back translation sustained by a pilot study. We performed constant comparative qualitative analysis for obtained relevant data. Results: Patient satisfaction and trust were associated with good verbal and non-verbal communication. Patient and physician responders recognized the benefit of empathy in building long-term relationships. Social and non-intimate expressive touches were positively perceived by patients, although within ethical and religious boundaries. Male physicians expressed clear apprehension for the use of touch, especially towards female patients, due to religious considerations. On the other hand, touch from female physicians was reportedly accepted by patients of both genders, while touch from their male counterparts was associated with more uneasiness. Discussion and Conclusions: Religious concerns are prevalent among Lebanese physicians and patients alike. However, the use of reassuring physical touch is still a cornerstone of the patient-physician relationship in Lebanon, albeit with some limitations. The potential therapeutic effect of verbal and non-verbal communication is evident and warrants further investigation. Communication training efforts should emphasize the importance of religiously and ethically appropriate expressive touch in healthcare. This would serve to promote positive physician and patient perceptions of this practice and improve clinical communication and expressiveness.

Summary Background Few options exist for treatment of patients with small-cell lung cancer (SCLC) after failure of first-line therapy. Lurbinectedin is a selective inhibitor of oncogenic transcription. In this phase 2 study, we evaluated the acti and safety of lurbinectedin in patients with SCLC after failure of platinum-based chemotherapy. Methods In this single-arm, open-label, phase 2 basket trial, we recruited patients from 26 hospitals in six European countries and the USA. Adults (aged ≥18 years) with a pathologically proven diagnosis of SCLC, Eastern Cooperative Oncology Group performance status of 2 or lower, measurable disease as per Response Criteria in Solid Tumors (RECIST) version 1.1, absence of brain metastasis, adequate organ function, and pre-treated with only one previous chemotherapy-containing line of treatment (minimum 3 weeks before study initiation) were eligible. Treatment consisted of 3·2 mg/m2 lurbinectedin administered as a 1-h intravenous infusion every 3 weeks until disease progression or unacceptable toxicity. The primary outcome was the proportion of patients with an overall response (complete or partial response) as assessed by the investigators according to RECIST 1.1. All treated patients were analysed for activity and safety. This study is ongoing and is registered with ClinicalTrials.gov , NCT02454972 . Findings Between Oct 16, 2015, and Jan 15, 2019, 105 patients were enrolled and treated with lurbinectedin. Median follow-up was 17·1 months (IQR 6·5–25·3). Overall response by investigator assessment was seen in 37 patients (35·2%; 95% CI 26·2–45·2). The most common grade 3–4 adverse events (irrespective of causality) were haematological abnormalities—namely, anaemia (in nine [9%] patients), leucopenia (30 [29%]), neutropenia (48 [46%]), and thrombocytopenia (seven [7%]). Serious treatment-related adverse events occurred in 11 (10%) patients, of which neutropenia and febrile neutropenia were the most common (five [5%] patients for each). No treatment-related deaths were reported. Interpretation Lurbinectedin was active as second-line therapy for SCLC in terms of overall response and had an acceptable and manageable safety profile. Lurbinectedin could represent a potential new treatment for patients with SCLC, who have few options especially in the event of a relapse, and is being investigated in combination with doxorubicin as second-line therapy in a randomised phase 3 trial.

Patient: Female, 43 Final Diagnosis: Metastatic breast cancer Symptoms: Breast lesion, breast tumor Medication: — Clinical Procedure: Chest wall reconstruction with a bilayered wound matrix mesh following toilet mastectomy Specialty: Surgery Objective: Unusual or unexpected effect of treatment Background: Breast cancer is still the most common malignancy in women. Though management of local disease has been thoroughly studied, management of metastatic breast cancer (MBC) is still under much debate. Modern diagnostic tools allow the detection of early metastatic disease, which may be more responsive to treatment than late metastatic disease. Source control of MBC by “toilet mastectomy” is being studied in many case reports and studies. Case Report: We present the case of a 43-year-old woman presenting with MBC and complaining of a recurrent breast fungating disease, aiming to highlight the importance of palliative surgical treatment in systemic breast malignancy and to report our experience with the effectiveness of the ‘Integra” mesh. Conclusions: Chest wall reconstruction using bilayered wound matrix mesh following “toilet mastectomy” offers excellent reconstructive results and local control of disease, and is a low-morbidity procedure.

Background In vitro/in vivo data showed synergism of cisplatin and lurbinectedin in ovarian cancer cells and grafts. This phase I trial investigated the recommended phase II dose (RD) of cisplatin and lurbinectedin combination, with (Group A) or without aprepitant (Group B), in patients with advanced solid tumors. Patients and Methods All patients received 60 mg/m2 cisplatin 90-min intravenous (i.v.) infusion followed by lurbinectedin 60-min i.v. infusion at escalating doses on Day 1 every 3 weeks (q3wk). Patients in Group A additionally received orally 125 mg aprepitant one hour before cisplatin on Day 1 and 80 mg on Days 2 and 3. Toxicity was graded according to the NCI-CTCAE v.4. Results RD for Group A was cisplatin 60 mg/m2 plus lurbinectedin 1.1 mg/m2. RD for Group B was cisplatin 60 mg/m2 plus lurbinectedin 1.4 mg/m2. The most frequent grade ≥ 3 adverse events were hematological [neutropenia (41%), lymphopenia (35%), leukopenia (24%), thrombocytopenia (18%)] and fatigue (35%) in Group A (n = 17), and neutropenia (50%), leukopenia (42%), lymphopenia (29%), and fatigue (13%) and nausea (8%) in Group B (n = 24). Four patients (2 in each group) had a partial response. Disease stabilization for ≥ 4 months was observed in 4 and 10 patients, respectively. Conclusion The combination of lurbinectedin with cisplatin was not possible in meaningful therapeutic dosage due to toxicity. The addition of aprepitant in combination with cisplatin did not allow increasing the dose due to hematological toxicity, whereas omitting aprepitant increased the incidence of nausea and vomiting. Modest clinical activity was observed in general. Clinical trial registration www.ClinicalTrials.gov code: NCT01980667. Date of registration: 11 November 2013.

Patient: Female, 30-year-old Final Diagnosis: Gastric ectopic pancreas Symptoms: — Medication: — Clinical Procedure: Laparscopic sleeve gastrectomy Specialty: Surgery Objective: Rare disease Background: Ectopic or heterotopic pancreas is relatively rare pathology described as pancreatic tissue lacking communication with the normal pancreas. Ectopic pancreatic tissue can be found along the gastrointestinal tract, with the most common location the stomach along the greater curvature. This congenital condition could be identified incidentally, or present with symptoms that range from pain and bleeding to obstruction and malignant transformation. Case Report: We report a case of a 30-year-old female, who underwent laparoscopic sleeve gastrectomy for morbid obesity of body mass index (BMI) of 46 kg/m2, and who was found to have a 3 cm submucosal mass at the lesser curvature while dividing the stomach. The sleeved stomach tube’s intraoperative gastroscopy showed a submucosal mass at the posterior stomach wall towards the lesser curvature, increasing the suspicion of gastrointestinal stromal tumor (GIST) tumor. The choice was to continue with a secure margin and conversion to roux-en-y gastric bypass with gastric tumor resection. It turned out that the final pathology was submucosal ectopic pancreas. Despite being a rare pathology, for any submucosal gastric mass, ectopic pancreas should be on the differential diagnosis list. During the sleeve surgery, the mass was found, and the approach was changed to intraoperatively subtotal gastrectomy and roux-en-y gastric bypass. Conclusions: Before any bariatric operation, even in asymptomatic young patients, it is worth doing routine upper endoscopy to prevent surprising intraoperative pathology.

Background Brucellosis is a zoonotic disease caused by Brucella spp., namely B. melitensis and B. abortus in humans. Culturing is the gold standard method for diagnosis; however, because Brucella is a slow-growing bacterium, which may delay diagnosis, other faster methods, such as serology, are used. Studies on the correlation between Brucella antibody titers and clinical outcomes are limited. Therefore, this study assessed such correlation and evaluated the correlation between baseline serological results with culture positivity and clinical picture. Methods Patients tested positive for Brucella antibodies at baseline and diagnosed with brucellosis between January 2008 and December 2018 were included. Collected data included clinical outcomes, baseline culture positivity (growth in culture), arthralgia, baseline and end of therapy (EOT) temperature, white blood cell count, C-reactive protein level, and erythrocyte sedimentation rate. Results Of 695 patients tested for Brucella antibodies, only 94 had positive baseline serology and diagnosed with acute brucellosis, among whom 63 had EOT serology. No significant correlations were found between EOT antibody titers of both Brucella spp. and clinical cure, mortality, length of stay, and duration of therapy. Additionally, no correlations were found between baseline serology and culture positivity, arthralgia, temperature, and other lab values. Conclusion Brucella serology does not correlate with clinical outcomes at EOT nor with culture positivity at baseline. Therefore, healthcare providers are advised to consider the whole clinical picture of a brucellosis patient without relying solely on serological results during follow up and not replace culturing with serology testing alone at the time of diagnosis.

Globe artichoke is an intriguing source of indigestible sugar polymers such as inulin-type fructans. In this study, the effect of ultrasound in combination with ethanol precipitation to enhance the extraction of long chain fructans from artichoke wastes has been evaluated. The inulin-type fructans content both from bracts and stems was measured using an enzymatic fructanase-based assay, while its average degree of polymerization (DP) was determined by HPLC-RID analysis. Results show that this method provides artichoke extracts with an inulin-type fructans content of 70% with an average DP between 32 and 42 both in bracts and in stems. The prebiotic effect of long chain inulins from artichoke extract wastes was demonstrated by its ability to support the growth of fiveLactobacillusand fourBifidobacteriumspecies, previously characterized as probiotics. Besides, we considered the possibility to industrialize the process developing a simpler method for the production of inulin-type fructans from the artichoke wastes so that the artichoke inulin preparation could be suitable for its use in synbiotic formulations in combination with different probiotics for further studies includingin vivotrials.

SummaryBackground A phase I study found remarkable activity and manageable toxicity for doxorubicin (bolus) plus lurbinectedin (1-h intravenous [i.v.] infusion) on Day 1 every three weeks (q3wk) as second-line therapy in relapsed small cell lung cancer (SCLC). An expansion cohort further evaluated this combination. Patients and methods Twenty-eight patients with relapsed SCLC after no more than one line of cytotoxic-containing chemotherapy were treated: 18 (64%) with sensitive disease (chemotherapy-free interval [CTFI] ≥90 days) and ten (36%) with resistant disease (CTFI Results Ten patients showed confirmed response (overall response rate [ORR] = 36%); median progression-free survival (PFS) = 3.3 months; median overall survival (OS) = 7.9 months. ORR was 50% in sensitive disease (median PFS = 5.7 months; median OS = 11.5 months) and 10% in resistant disease (median PFS = 1.3 months; median OS = 4.6 months). The main toxicity was transient and reversible myelosuppression. Treatment-related non-hematological events (fatigue, nausea, decreased appetite, vomiting, alopecia) were mostly mild or moderate. Conclusion Doxorubicin 40 mg/m2 and lurbinectedin 2.0 mg/m2 on Day 1 q3wk has shown noteworthy activity in relapsed SCLC and a manageable safety profile. The combination is being evaluated as second-line therapy for SCLC in an ongoing, randomized phase III trial. Clinical trial registrationwww.ClinicalTrials.gov code: NCT01970540.

Candida kefyr (Kluyveromyces marxianus) is a clinically important infectious yeast. It is found in nature, and is known to cause diseases in humans. No previous studies known have shown the detection of Candida kefyr in water sources of any country, and no studies have detected it anywhere in Lebanon. This present study is carried out to assess the quality of Lebanese water in terms of yeast pollution. The occurrence of Candida spp. (species) was inspected in 84 water samples that tested positive for containing Candida. Out of all isolates, 12 isolates were of C. kefyr and two were of P. kluyveri. The identification of Candida sp. was carried out by using HiCrome™ M1297A and M1297AR chromogenic media. Isolates identified were confirmed by MALDI-TOF MS and 26S rRNA sequencing. The isolates varied from sensitive to resistant to common antifungal agents, including Itraconazole, clotrimazole, fluconazole, miconazole, and nystatin, via disk diffusion assay. These results are the first to confirm the presence of C. kefyr in Lebanese water supplies and suggest that water consumed in Lebanon may be a potential transmission route for serious Candida-based infections.

Introduction: The National Comprehensive Cancer Network guidelines recommend re-challenge with the first-line treatment for relapsed small cell lung cancer (SCLC) with chemotherapy-free interval (CTFI)≥180 days. A phase II study (NCT02454972) showed remarkable antitumor activity in SCLC patients treated with lurbinectedin 3.2 mg/m2 1 -h intravenous infusion every 3 weeks as second-line therapy. We report results for the pre-planned subset of patients with CTFI ≥ 180 days. Material and Methods: Twenty patients aged ≥18 years with pathologically proven SCLC diagnosis, pretreated with only one prior platinum-containing line, no CNS metastases, and with CTFI ≥ 180 days were evaluated. The primary efficacy endpoint was the overall response rate (ORR) assessed by the Investigators according to RECIST v1.1. Results: ORR was 60.0 % (95 %CI, 36.1−86.9), with a median duration of response of 5.5 months (95 %CI, 2.9−11.2) and disease control rate of 95.0 % (95 %CI, 75.1−99.9). Median progression-free survival was 4.6 months (95 %CI, 2.6−7.3). With a censoring of 55.0 %, the median overall survival was 16.2 months (95 %CI, 9.6-upper level not reached). Of note, 60.9 % and 27.1 % of patients were alive at 1 and 2 years, respectively. The most common grade 3/4 adverse events and laboratory abnormalities were hematological disorders (neutropenia, 55.0 %; anemia; 10.0 % thrombocytopenia, 10.0 %), fatigue (10.0 %) and increased liver function tests (GGT, 10 %; ALT and AP, 5.0 % each). No febrile neutropenia was reported. Conclusion: Lurbinectedin is an effective treatment for platinum-sensitive relapsed SCLC, especially in patients with CTFI ≥ 180 days, with acceptable safety and tolerability. These encouraging results suggest that lurbinectedin can be another valuable therapeutic option rather than platinum re-challenge., SCOPUS: ar.j, info:eu-repo/semantics/published

Objectives We determined the central nervous system (CNS) efficacy of alectinib by calculating time to CNS progression and cumulative incidence rates (CIRs) of CNS progression, non-CNS progression and death in patients with anaplastic lymphoma kinase (ALK)-positive non-small-cell lung cancer (NSCLC) enrolled in the J-ALEX phase III study. Materials and methods Japanese patients aged ≥20 years with ALK-positive NSCLC who were ALK inhibitor-naive and chemotherapy-naive, or who had received one previous chemotherapy regimen, were enrolled. Patients with treated or untreated asymptomatic CNS metastases were eligible. Treatment comprised oral alectinib 300 mg twice daily or crizotinib 250 mg twice daily until progressive disease, unacceptable toxicity, death or withdrawal. Imaging scans (computed tomography/magnetic resonance imaging) were taken at baseline and at regular intervals throughout the study. The CIRs for CNS progression, non-CNS progression and death were calculated for patients with and without baseline CNS metastases using a competing risks method. Results The hazard ratio for time to CNS progression in patients with and without baseline CNS metastases was 0.51 (95% confidence interval [CI]: 0.16–1.64; P = 0.2502) and 0.19 (95% CI: 0.07–0.53; P = 0.0004), respectively. The CIRs of CNS progression and non-CNS progression were lower in the alectinib group than in the crizotinib group at all time points. The 1-year CIRs of CNS progression were 16.8% and 5.9% with crizotinib and alectinib, respectively, and the 1-year CIRs of non-CNS progression were 38.4% and 17.5%, respectively. Comparable findings were obtained in patients with or without baseline CNS metastases. Conclusion Alectinib appears to avert the progression of CNS metastases in patients with ALK-positive NSCLC and baseline CNS metastases, and to prevent the development of new CNS lesions in patients without baseline CNS disease.

Background: Equinus is a common foot deformity in patients with cerebral palsy (CP). However, its prevalence is scarcely reported in the literature. Therefore, we conducted this review to estimate the prevalence of equinus foot in CP. Methods: Eight databases were searched. Our primary outcome was the prevalence of equinus foot in CP patients. Subgroup analysis was conducted based on study design, the laterality of CP, and whether equinus foot was defined or not. Results: The prevalence of equinus foot in CP was 93% (95% CI: 71–99). The prevalence was 99% (95% CI: 55–100), 96% (95% CI: 57–100), and 65% (95% CI: 37–86) in unilateral, both, and bilateral CP, respectively. Based on study design, equinus foot prevalence was 92% (95% CI: 34–100) in case series and 62% (95% CI: 47–74) in cohort studies. Four studies reported definition criteria for equinus foot, with a pooled prevalence rate of equinus foot of 99% (95% CI: 36–100) compared to a rate of 89% (95% CI: 59–98) among studies that lacked a definition criterion. Conclusions: This is the first meta-analysis to address the prevalence of equinus foot in CP patients. Although its prevalence is very high, our findings should be interpreted with caution due to the presence of multiple limitations, such as the lack of standardized definition criteria for equinus foot, the inappropriate study design, the wide confidence interval of equinus foot rate, and the small number of studies investigating it as a primary outcome.

5586 Background: LUR is a new agent that exerts antitumor activity through inhibition of trans-activated transcription and modulation of tumor microenvironment. Preclinical synergism/additivity in combination with IRI has been reported, thus prompting the conduct of this trial. This synergism had been evaluated and recently reported in patients with Small Cell Lung Cancer, with encouraging results (Ponce et al. WCLC, 2020). Methods: Phase I trial to evaluate escalating doses of LUR on Day (D) 1 plus a fixed dose of IRI 75 mg/m2 on D1 and D8 every 3 weeks (q3w) in pts with advanced solid tumors, enrolled following a standard 3+3 dose escalation design. Phase II to expand in selected indications at the Recommended Dose (RD). In this abstract, the cohort of patients with endometrial carcinoma treated at the RD is presented. Results: 21 pts (all female) with endometrial carcinoma were treated at the RD (LUR 2 mg/m2 + IRI 75 mg/m2 + G-CSF); 57% had ECOG PS=1; median age was 64 years (range 34-74); subtype of tumour was split: 67% (14 pts) endometroid, 33% non-endometroid (3 pts serous-papilar, 3 pts clear-cell and 1 pt undifferentiated); median of 2 prior lines (range, 1−7) per pt. Common G1/2 toxicities were nausea, vomiting, fatigue, diarrhea and anorexia; G3/4 hematological toxicities comprised neutropenia (33%), thrombocytopenia (5%) and anemia (38%). Two episodes of febrile neutropenia occurred (9.5%). G3/4 non hematological toxicities consisted of diarrhea (24%), asthenia (19%), nausea (14%) and vomiting (5%), all were transient and manageable. 1 patient (5%) discontinued treatment due to toxicity drug-related (generalized muscular weakness), but no treatment-related deaths were reported. Objective RECIST responses were documented in 4/21 evaluable pts (19%). With 6 pts censored for progression, median PFS was 4.4 months (95% CI 2.1-9.6 months), and PFS at 6 months was 40.4%. The clinical benefit rate (% of pts with Complete Response (CR), Partial Response (PR) or Stable Disease > 4 months) was 43%, and the Disease Control Rate (% of pts with CR, PR or SD) 81%. 3/21 pts (14%) have been more than 12 months on treatment so far. Conclusions: The combination of Lurbinectedin and Irinotecan is active in heavily pretreated patients with endometrial carcinoma. The combination was well-tolerated and consistent with the known safety profile for this combination. Myelosuppression, diarrhea, nausea and asthenia were predictable and manageable. Updated results of this cohort will be presented at the meeting. Clinical trial information: NCT02611024.

3078 Background: PM14 is a new chemical entity that forms DNA adducts which specifically inhibit RNA synthesis and block active transcription of protein-coding genes. Antitumor activity has been demonstrated in vitro in several cell lines (e.g. lung, kidney, prostate), and in vivo in mice bearing xenografted human-derived tumors (soft tissue sarcoma, small cell lung cancer, ovarian, gastric, breast and renal cancer). Methods: Open-label, dose-escalating, phase I trial of PM14 administered as a 3-hour infusion i.v. every 3 weeks (q3wk) in patients (pts) with advanced solid tumors, adequate organ function and ECOG PS score of 0-1. Two schedules were explored: Schedule A (Day 1 [D1], Day 8 [D8]) and Schedule B (D1). Results: 37 pts were treated (Schedule A/B: 28/9 pts). Baseline characteristics of pts (A/B): median age 56/47 years; male 57%/56%; ECOG PS 0: 57%/56%; median of prior lines (range): 3 (1-8)/4 (1-10). Most common tumor types (A + B): STS (n=7 pts), ovarian (n=6), pancreatic (n=4), prostate cancer (n=3). The maximum tolerated dose was 4.5 mg/m2 for A (dose-limiting toxicities [DLTs]: D8 omission due to lack of recovery of lab parameters for re-treatment [n=2 pts]) and 5.6 mg/m2 (DLTs: G4 febrile neutropenia [n=1], G4 transaminase increase [n=1]) for B. The recommended dose (RD) was 3.0 mg/m2 on D1,D8 (A), and 4.5 mg/m2 on D1 (B). No DLTs were present at the RDs. Most common toxicities were hematological abnormalities and transaminase increase. Main toxicities at the RDs are shown below. Antitumor activity comprised stable disease ≥4 months in 7 heavily pretreated pts (6 in A; 1 in B) at all dose levels. Linear pharmacokinetics were observed for PM14 at tested doses (0.25-5.6 mg/m²), with geometric mean (CV%) total plasma clearance 5.9 L/h (88%), volume of distribution 128 L (81%) and median (range) terminal half-life 15.9 h (7.5-34.3 h). Less than 1.6% of administered dose was recovered in urine. Conclusions: RDs were determined for two PM14 schedules in pts with advanced solid tumors. At the RDs, PM14 is well tolerated and has a manageable safety profile. An expansion phase in specific tumor types, with an optional Bayesian continual reassessment method for RD fine-tuning, is ongoing with both schedules.[Table: see text]

Background: Central nervous system (CNS) progression is common in patients with anaplastic lymphoma kinaseepositive (ALK+) non-small-cell lung cancer (NSCLC) receiving crizotinib. Next-generation ALK inhibitors have shown activity against CNS metastases, but accurate assessment of response and progression is vital. Data from two phase II studies in crizotinib-refractory ALK+ NSCLC were pooled to examine the CNS efficacy of alectinib, a CNS-active ALK inhibitor, using Response Evaluation Criteria in Solid Tumours (RECIST version 1.1) and Response Assessment in Neuro-Oncology high-grade glioma (RANO-HGG) criteria.Methods: Both studies enrolled patients aged >= 18 years who had previously received crizotinib. NP28761 was conducted in North America and NP28673 was a global study. All patients received 600 mg oral alectinib twice daily and had baseline CNS imaging. CNS response for those with baseline CNS metastases was determined by an independent review committee.Results: Baseline measurable CNS disease was identified in 50 patients by RECIST and 43 by RANO-HGG. CNS objective response rate was 64.0% by RECIST (95% confidence interval [CI]: 49.2-77.1; 11 CNS complete responses [CCRs]) and 53.5% by RANO-HGG (95% CI: 37.7-68.8; eight CCRs). CNS responses were durable, with consistent estimates of median duration of 10.8 months with RECIST and 11.1 months with RANO-HGG. Of the 39 patients with measurable CNS disease by both RECIST and RANO-HGG, only three (8%) had CNS progression according to one criteria but not the other (92% concordance rate).Conclusion: Alectinib demonstrated promising efficacy in the CNS for ALK+ NSCLC patients pretreated with crizotinib, regardless of the assessment criteria used.

Alectinib, a highly selective inhibitor of anaplastic lymphoma kinase (ALK), has shown systemic and central nervous system (CNS) efficacy in the treatment of ALK-positive non-small-cell lung cancer (NSCLC). We investigated alectinib as compared with crizotinib in patients with previously untreated, advanced ALK-positive NSCLC, including those with asymptomatic CNS disease. In a randomized, open-label, phase 3 trial, we randomly assigned 303 patients with previously untreated, advanced ALK-positive NSCLC to receive either alectinib (600 mg twice daily) or crizotinib (250 mg twice daily). The primary end point was investigator-assessed progression-free survival. Secondary end points were independent review committee-assessed progression-free survival, time to CNS progression, objective response rate, and overall survival. During a median follow-up of 17.6 months (crizotinib) and 18.6 months (alectinib), an event of disease progression or death occurred in 62 of 152 patients (41%) in the alectinib group and 102 of 151 patients (68%) in the crizotinib group. The rate of investigator-assessed progression-free survival was significantly higher with alectinib than with crizotinib (12-month event-free survival rate, 68.4% [95% confidence interval (CI), 61.0 to 75.9] with alectinib vs. 48.7% [95% CI, 40.4 to 56.9] with crizotinib; hazard ratio for disease progression or death, 0.47 [95% CI, 0.34 to 0.65]; P

Purpose Alectinib has shown activity in the CNS in phase I and II studies. To further evaluate this activity, we pooled efficacy and safety data from two single-arm phase II studies (NP28761 and NP28673; ClinicalTrials.gov identifiers: NCT01871805 and NCT01801111, respectively) in patients with ALK-positive non–small-cell lung cancer (NSCLC). Patients and Methods Both studies included patients with ALK-positive NSCLC who had previously received crizotinib; all patients received alectinib 600 mg twice per day. The primary end point in both studies was independent review committee (IRC)–assessed objective response rate (ORR; by Response Evaluation Criteria in Solid Tumors [RECIST] version 1.1). Additional end points (all by IRC) included CNS ORR (CORR), CNS disease control rate (CDCR), and CNS duration of response (CDOR). Results One hundred thirty-six patients had baseline CNS metastases (60% of the overall study populations); 50 patients (37%) had measurable CNS disease at baseline. Ninety-five patients (70%) had prior CNS radiotherapy; 55 patients completed the CNS radiotherapy more than 6 months before starting alectinib. Median follow-up time was 12.4 months (range, 0.9 to 19.7 months). For patients with baseline measurable CNS disease, IRC CORR was 64.0% (95% CI, 49.2% to 77.1%), CDCR was 90.0% (95% CI, 78.2% to 96.7%), and median CDOR was 10.8 months (95% CI, 7.6 to 14.1 months). For patients with measurable and/or nonmeasurable baseline CNS disease, IRC CORR was 42.6% (95% CI, 34.2% to 51.4%), CDCR was 85.3% (95% CI, 78.2% to 90.8%), and median CDOR was 11.1 months (95% CI, 10.3 months to not evaluable). CORR was 35.8% (95% CI, 26.2% to 46.3%) for patients with prior radiotherapy (n = 95) and 58.5% (95% CI, 42.1% to 73.7%) for patients without prior radiotherapy (n = 41). As previously reported, alectinib was well tolerated, regardless of baseline CNS disease. Conclusion Alectinib showed good efficacy against CNS metastases, in addition to systemic activity, in crizotinib-refractory ALK-positive NSCLC.

Brucellosis is a zoonotic disease caused by Brucella spp., namely B. meletinsis and B. abortus in humans. Studies on the correlation between Brucella antibody titers and clinical outcomes are limited. Therefore, this study assessed such correlation and evaluated the correlation between baseline serologic results with culture positivity and clinical picture. Patients tested positive for Brucella antibodies at baseline and diagnosed with brucellosis between January 2008 and December 2018 were included. Collected data included clinical outcomes, baseline culture positivity, arthralgia, baseline and EOT temperature, white blood cell (WBC) count, C-reactive protein level, and erythrocyte sedimentation rate. Of 695 patients tested for Brucella antibodies, only 94 had positive baseline serology and diagnosed with brucellosis, among whom 63 had EOT serology. No significant correlations were found between EOT antibody titers of both Brucella spp. and clinical cure, mortality, length of stay, and duration of therapy. Additionally, no correlations were found between baseline serology and culture positivity, arthralgia, temperature, and other lab values. Brucella serology does not correlate with clinical outcomes at EOT nor with culture positivity at baseline. Therefore, healthcare providers are advised to consider the whole clinical picture of a brucellosis patient without relying solely on serologic results during follow up and not replace culturing with serology testing alone at the time of diagnosis.

The anaplastic lymphoma kinase (ALK) inhibitor alectinib is an effective treatment for ALK-positive non-small-cell lung cancer. This bioequivalence study evaluated the in vivo performance of test 3 formulations with the reduced wetting agent sodium lauryl sulfate (SLS) content. This randomized, 4-period, 4-sequence, crossover study compared alectinib (600 mg) as 25%, 12.5%, and 3% SLS hard capsule formulations with the reference 50% SLS clinical formulation in healthy subjects under fasted conditions (n = 49), and following a high-fat meal (n = 48). Geometric mean ratios and 90% confidence intervals (CIs) for Cmax , AUC0-last , and AUC0-∞ of alectinib, its major active metabolite, M4, and alectinib plus M4 were determined for the test formulations versus the reference formulation. Bioequivalence was concluded if the 90%CIs were within the 80% to 125% boundaries. The 25% SLS formulation demonstrated bioequivalence to the reference 50% SLS formulation for Cmax , AUC0-last , and AUC0-∞ of alectinib, M4, and alectinib plus M4 under both fasted and fed conditions. Further reductions in SLS content (12.5% and 3% SLS) did not meet the bioequivalence criteria. Cross-group comparisons showed an approximately 3-fold positive food effect. Reducing SLS to 25% resulted in a formulation that is bioequivalent to the current 50% SLS formulation used in alectinib pivotal trials.

Purpose Crizotinib confers improved progression-free survival compared with chemotherapy in anaplastic lymphoma kinase (ALK)-rearranged non–small-cell lung cancer (NSCLC), but progression invariably occurs. We investigated the efficacy and safety of alectinib, a potent and selective ALK inhibitor with excellent CNS penetration, in patients with crizotinib-refractory ALK-positive NSCLC. Patients and Methods Alectinib 600 mg was administered orally twice daily. The primary end point was objective response rate (ORR) by central independent review committee (IRC). Results Of the 138 patients treated, 84 patients (61%) had CNS metastases at baseline, and 122 were response evaluable (RE) by IRC. ORR by IRC was 50% (95% CI, 41% to 59%), and the median duration of response (DOR) was 11.2 months (95% CI, 9.6 months to not reached). In 96 patients (79%) previously treated with chemotherapy, the ORR was 45% (95% CI, 35% to 55%). Median IRC-assessed progression-free survival for all 138 patients was 8.9 months (95% CI, 5.6 to 11.3 months). CNS disease control rate was 83% (95% CI, 74% to 91%), and the median CNS DOR was 10.3 months (95% CI, 7.6 to 11.2 months). CNS ORR in 35 patients with baseline measurable CNS lesions was 57% (95% CI, 39% to 74%). Of the 23 patients with baseline CNS metastases (measurable or nonmeasurable) and no prior radiation, 10 (43%) had a complete CNS response. At 12 months, the cumulative CNS progression rate (24.8%) was lower than the cumulative non-CNS progression rate (33.2%) for all patients. Common adverse events were constipation (33%), fatigue (26%), and peripheral edema (25%); most were grade 1 to 2. Conclusion Alectinib is highly active and well tolerated in patients with advanced, crizotinib-refractory ALK-positive NSCLC, including those with CNS metastases.

3514 Background: LUR is a novel agent that exerts antitumor activity through inhibition of trans-activated transcription and modulation of tumor microenvironment. Preclinical synergism/additivity in combination with IRI has been reported, thus prompting the conduct of this clinical trial. Methods: Phase Ib-II trial to evaluate escalating doses of LUR on Day (D) 1 plus a fixed dose of IRI 75 mg/m2 on D1 and D8 every 3 weeks (q3w) in pts with advanced solid tumors (+/- G-CSF, if dose-limiting toxicities [DLTs] were neutropenia). Starting dose was LUR 1.0 m/m2 + IRI 75 mg/m2. Results: 77 pts have been treated to date at 5 dose levels, 51 of them at the recommended dose (RD). Baseline characteristics of all 77 pts were: 48% females, 68% ECOG PS=1; median age 57 years (range, 19-75 years); median of 2 prior lines (range, 0−4 lines). The maximum tolerated dose (MTD) was LUR 2.4 mg/m2 + IRI 75 mg/m2 with G-CSF, and the RD was LUR 2.0 mg/m2 + IRI 75 mg/m2 with G-CSF. DLTs in Cycle 1 occurred in 2/3 evaluable pts at the MTD and 3/13 evaluable pts at the RD, and comprised omission of IRI D8 infusion due to grade (G) 3/4 neutropenia (n=3 pts) or G2-4 thrombocytopenia (n=2). At the RD (n=51), common G1/2 non-hematological toxicities were nausea, vomiting, fatigue, diarrhea, anorexia and neuropathy. G3 non-hematological toxicities (diarrhea 10%, fatigue 10%) and G3/4 hematological abnormalities (neutropenia 49%, thrombocytopenia 10%) were transient. Conclusions: The combination of LUR and IRI had acceptable tolerance, with no unexpected toxicities. Transient myelosuppression was dose-limiting. The RD is LUR 2.0 mg/m2 on D1 + IRI 75 mg/m2 on D1 and D8 q3w with G-CSF. Antitumor activity was observed at the RD in SCLC pts, as well as in endometrial carcinoma pts. Hints of activity were also observed in STS pts. Updated results will be presented. Clinical trial information: NCT02611024 . [Table: see text]

3635 Background: Lurbinectedin (L), an inhibitor of active transcription, has shown activity in second-line (2L) small cell lung cancer (SCLC) (ASCO 2019). Topotecan (T) is the only approved drug in 2L SCLC and is also used in platinum resistant ovarian cancer (PROC). Methods: This pooled safety analysis includes data from 554 patients (pts) treated with L at 3.2 mg/m2 Day 1 q3wk 1-h (no primary prophylaxis with G-CSF required): 335 with selected solid tumors (9 indications, including 105 pts with SCLC) from a phase II Basket study and 219 with PROC in the phase III CORAIL study. An indirect exploratory comparison (pooled data from CORAIL + Basket) and a direct comparison (data from CORAIL) of L vs. T are presented. Results: Most common adverse events with L were grade 1/2 fatigue, nausea and vomiting. Treatment-related (L/T): dose reductions: 22.9/48.3%, delays: 25.8/52.9%, grade ≥3 serious adverse events (SAEs): 15.0/32.2%, discontinuations: 3.2/5.7%, deaths: 1.3/1.5%, G-CSF use: 23.8/70.1%, and transfusions: 15.9/52.9%. Conclusions: Lurbinectedin has a predictable and manageable safety profile. A significant safety advantage was observed when lurbinectedin was compared with topotecan in the CORAIL trial in terms of hematological toxicities. With the limitations of indirect comparisons, in the pooled safety analysis, fewer lurbinectedin-treated pts had severe hematological toxicities, SAEs, dose adjustments, treatment discontinuations and use of supportive treatments than topotecan-treated pts. Clinical trial information: NCT02421588 and NCT02454972 . [Table: see text]

The phase III ALEX study in patients with treatment-naive advanced anaplastic lymphoma kinase mutation-positive (ALK+) non-small-cell lung cancer (NSCLC) met its primary end point of improved progression-free survival (PFS) with alectinib versus crizotinib. Here, we present detailed central nervous system (CNS) efficacy data from ALEX. Overall, 303 patients aged ≥18 years underwent 1:1 randomization to receive twice-daily doses of alectinib 600 mg or crizotinib 250 mg. Brain imaging was conducted in all patients at baseline and every subsequent 8 weeks. End points (analyzed by subgroup: patients with/without baseline CNS metastases; patients with/without prior radiotherapy) included PFS, CNS objective response rate (ORR), and time to CNS progression. In total, 122 patients had Independent Review Committee-assessed baseline CNS metastases (alectinib, n = 64; crizotinib, n = 58), 43 had measurable lesions (alectinib, n = 21; crizotinib, n = 22), and 46 had received prior radiotherapy (alectinib, n = 25; crizotinib, n = 21). Investigator-assessed PFS with alectinib was consistent between patients with baseline CNS metastases [hazard ratio (HR) 0.40, 95% confidence interval (CI): 0.25-0.64] and those without (HR 0.51, 95% CI: 0.33-0.80, P interaction = 0.36). Similar results were seen in patients regardless of prior radiotherapy. Time to CNS progression was significantly longer with alectinib versus crizotinib and comparable between patients with and without baseline CNS metastases (P < 0.0001). CNS ORR was 85.7% with alectinib versus 71.4% with crizotinib in patients who received prior radiotherapy and 78.6% versus 40.0%, respectively, in those who had not. Alectinib demonstrated superior CNS activity and significantly delayed CNS progression versus crizotinib in patients with previously untreated, advanced ALK+ NSCLC, irrespective of prior CNS disease or radiotherapy.

The excessive increase in carbon dioxide emissions through the past several decades has raised global climate change concerns. As such, environmental policy makers have been looking into the implementation of efficient strategies that would ultimately reduce greenhouse gas (GHG) emission levels, and meet strict emissions targets. As part of a national emission reduction strategy, the reduction of carbon-dioxide emissions from industrial activities has been proven to be very significant. This instigated the need for a systematic carbon integration approach that can yield cost-effective carbon integration networks, while meeting prescribed carbon dioxide emission reduction targets in industrial cities. A novel carbon integration methodology has been previously proposed as a carbon network source-sink mapping approach using a Mixed Integer Nonlinear Program (MINLP), and was found to be very effective to devise emission control strategies in industrial cities. This paper aims to further improve the design process of carbon integration networks, by coupling carbon integration networks with hydrate suppression/moisture removal options. This was found vital for the prevention of any potential hazards that are associated with the transportation of carbon dioxide in pipelines, such as hydrate formation and various corrosion effects, which may result from moisture retention. An extensive analysis of carbon capture, dehydration, inhibition, compression, and transmission options have all been incorporated into the network design process, in the course of determining cost-optimal solutions for carbon dioxide networks. The proposed approach has been illustrated using an industrial city case study.

This is the first trial to directly compare efficacy and safety of alectinib versus standard chemotherapy in advanced/metastatic anaplastic lymphoma kinase (ALK)-positive non-small-cell lung cancer (NSCLC) patients who have progressed on, or were intolerant to, crizotinib.ALUR (MO29750; NCT02604342) was a randomized, multicenter, open-label, phase III trial of alectinib versus chemotherapy in advanced/metastatic ALK-positive NSCLC patients previously treated with platinum-based doublet chemotherapy and crizotinib. Patients were randomized 2 : 1 to receive alectinib 600 mg twice daily or chemotherapy (pemetrexed 500 mg/m2 or docetaxel 75 mg/m2, both every 3 weeks) until disease progression, death, or withdrawal. Primary end point was investigator-assessed progression-free survival (PFS).Altogether, 107 patients were randomized (alectinib, n = 72; chemotherapy, n = 35) in 13 countries across Europe and Asia. Median investigator-assessed PFS was 9.6 months [95% confidence interval (CI): 6.9-12.2] with alectinib and 1.4 months (95% CI: 1.3-1.6) with chemotherapy [hazard ratio (HR) 0.15 (95% CI: 0.08-0.29); P 0.001]. Independent Review Committee-assessed PFS was also significantly longer with alectinib [HR 0.32 (95% CI: 0.17-0.59); median PFS was 7.1 months (95% CI: 6.3-10.8) with alectinib and 1.6 months (95% CI: 1.3-4.1) with chemotherapy]. In patients with measurable baseline central nervous system (CNS) disease (alectinib, n = 24; chemotherapy, n = 16), CNS objective response rate was significantly higher with alectinib (54.2%) versus chemotherapy (0%; P 0.001). Grade ≥3 adverse events were more common with chemotherapy (41.2%) than alectinib (27.1%). Incidence of AEs leading to study-drug discontinuation was lower with alectinib (5.7%) than chemotherapy (8.8%), despite alectinib treatment duration being longer (20.1 weeks versus 6.0 weeks).Alectinib significantly improved systemic and CNS efficacy versus chemotherapy for crizotinib-pretreated ALK-positive NSCLC patients, with a favorable safety profile.ClinicalTrials.gov NCT02604342; Roche study MO29750.

Background In a phase II North American study (NP28761; NCT01871805), the anaplastic lymphoma kinase (ALK) inhibitor alectinib demonstrated both systemic and central nervous system (CNS) efficacy with good tolerability in patients with ALK-positive non-small cell lung cancer. We describe patient-reported outcomes (PROs) from the NP28761 study. Patients and methods PROs and health-related quality of life (HRQoL) benefits were assessed using two self-administered questionnaires (the European Organisation for Research and Treatment of Cancer 30-Item Quality of Life Questionnaire-Core (EORTC QLQ-C30), and the 13-item EORTC QLQ-lung cancer-specific module) at enrolment and every 6 weeks until week 66, disease progression or death. Results Clinically meaningful mean improvements (≥10 point change from baseline) were observed in 10 domains, including global health status (GHS), role and social functioning, fatigue, pain, dyspnoea, and appetite loss. A clinically meaningful improvement was observed in GHS from the first assessment (6 weeks) until week 60. Alectinib demonstrated a rapid effect, with a median time to symptom improvement, using the composite endpoint of cough, dyspnoea and pain in the chest, of 1.4 months (6.1 weeks) (95% CI 1.4 to 1.6) and a median time to symptom deterioration of 5.1 months (22.1 weeks) (95% CI 2.8 to 6.8). Patients with CNS metastases at baseline experienced comparable HRQoL over the duration of the study as patients without CNS metastases. Exploratory analysis showed that the occurrence of an objective response may be associated with a better HRQoL. Conclusions Patients treated with alectinib in this phase II study achieved clinically meaningful improvements in HRQoL and symptoms and had delayed time to symptom deterioration.

ABSTRACT Aim: This analysis investigates incidence and time course of rash in the EURTAC study. Materials & methods: Patients with EGFR mutation-positive non-small-cell lung cancer were randomized 1:1 to receive once daily erlotinib or 3-weekly cycles of chemotherapy. Results: Of the 86 erlotinib-treated patients, 71 reported rash. Median time to first rash appearance was 0.7 months. Most patients (n = 65) had the same or lower grade rash at final assessment compared with initial assessment. Of the 21 patients with decreased rash grade between initial and final assessments, 61.9% received no erlotinib dose modification, 42.8% had no concomitant rash treatment. Conclusion: Most rash cases were mild, occurred within 1 month of erlotinib treatment, and rapidly improved without the need for erlotinib dose alterations.

Introduction: Alectinib demonstrated clinical efficacy and an acceptable safety profile in two phase II studies (NP28761 and NP28673). Here we report the pooled efficacy and safety data after 15 and 18 months more follow-up than in the respective primary analyses.Methods: Enrolled patients had ALK receptor tyrosine kinase gene (ALK)-positive NSCLC and had progressed while taking, or could not tolerate, crizotinib. Patients received oral alectinib, 600 mg twice daily. The primary end point in both studies was objective response rate assessed by an independent review committee (IRC) using the Response Evaluation Criteria in Solid Tumors, version 1.1. Secondary end points included disease control rate, duration of response, progression-free survival, overall survival, and safety.Results: The pooled data set included 225 patients (n = 138 in NP28673 and n = 87 in NP28761). The response-evaluable population included 189 patients (84% [n = 122 in NP28673 and n = 67 in NP28761]). In the response-evaluable population, objective response rate as assessed by the IRC was 51.3% (95% confidence interval [CI]: 44.0-58.6 [all PRs]), the disease control rate was 78.8% (95% CI: 72.3-84.4), and the median duration of response was 14.9 months (95% CI: 11.1-20.4) after 58% of events. Median progression-free survival as assessed by the IRC was 8.3 months (95% CI: 7.0-11.3) and median overall survival was 26.0 months (95% CI: 21.4-not estimable). Grade 3 or higher adverse events (AEs) occurred in 40% of patients, 6% of patients had treatment withdrawn on account of AEs, and 33% had AEs leading to dose interruptions/modification.Conclusions: This pooled data analysis confirmed the robust systemic efficacy of alectinib in ALK-positive NSCLC with a durable response rate. Alectinib also had an acceptable safety profile with a longer duration of follow-up. (C) 2017 International Association for the Study of Lung Cancer. Published by Elsevier Inc.

Alectinib, a central nervous system (CNS)-active ALK inhibitor, has demonstrated efficacy and safety in ALK+ non-small-cell lung cancer that has progressed following crizotinib treatment. Other ALK inhibitors have shown concentration-dependent QTc prolongation and treatment-related bradycardia. Therefore, this analysis evaluated alectinib safety in terms of electrophysiologic parameters.Intensive triplicate centrally read electrocardiogram (ECG) and matched pharmacokinetic data were collected across two alectinib single-arm trials. Analysis of QTcF included central tendency analysis [mean changes from baseline with one-sided upper 95% confidence intervals (CIs)], categorical analyses, and relationship between change in QTcF and alectinib plasma concentrations. Alectinib effects on other ECG parameters (heart rate, PR interval and QRS duration) were also evaluated.Alectinib did not cause a clinically relevant change in QTcF. The maximum mean QTcF change from baseline was 5.3 ms observed pre-dose at week 2. The upper one-sided 95% CI was10 ms at all time points. There was no relevant relationship between change in QTcF and alectinib plasma concentrations. Alectinib treatment resulted in a generally asymptomatic exposure-dependent decrease in mean heart rate of ~11 to 13 beats per minute at week 2. No clinically relevant effects were seen on other ECG parameters. Approximately 5% of patients reported cardiac adverse events of bradycardia or sinus bradycardia; however, these were all grade 1-2.Alectinib does not prolong the QTc interval or cause changes in cardiac function to a clinically relevant extent, with the exception of a decrease in heart rate which was generally asymptomatic.

Background LUR is a new agent that exerts antitumor activity through inhibition of trans-activated transcription and modulation of tumor microenvironment. Preclinical synergism/additivity in combination with IRI has been reported, thus prompting the conduct of this trial. Methods Phase I trial to evaluate escalating doses of LUR on Day (D) 1 plus a fixed dose of IRI 75 mg/m2 on D1 and D8 every 3 weeks (q3w) in pts with advanced solid tumors, enrolled following a standard 3 + 3 dose escalation design. Results 39 pts were treated at 5 dose levels (DL); 13 at the recommended dose (RD). 56% were females, 69% had ECOG PS = 1; median age was 58 years; median of 2 prior chemotherapy lines for advanced disease (range, 0 − 4) per pt. RD was defined as LUR 2.0 mg/m2 on D1 + IRI 75 mg/m2 on D1 and D8 q3w + GCSF. Dose-limiting toxicities in Cycle 1 were observed in 2/3 evaluable pts at the maximum tolerated dose (MTD) and in 3/13 evaluable pts at the RD. At the MTD and the RD, DLTs were skipping IRI D8 doses due to grade (G) 3-4 neutropenia (n = 3 patients) or G2-4 thrombocytopenia (n = 2). At the RD common G1/2 toxicities were nausea, vomiting, fatigue, diarrhea, anorexia and neuropathy; G3/4 hematological abnormalities comprised neutropenia (33%), but no thrombocytopenia. Objective RECIST responses were documented in 6/34 evaluable pts (18%): 3/11 pts with small cell lung cancer (SCLC), 2/2 pts with endometrial carcinoma (EC) and 1/3 pts with glioblastoma (GB). Most responses (5/12 evaluable patients [42%]) were at the RD. One pt with EC has an ongoing PR after 20 cycles. Prolonged SD > 4 months were observed in pancreatic carcinoma (3/6 pts), soft tissue sarcoma (STS) (5/9 pts) and SCLC (6/11, including 4 with SD for 6, 9, 11 and 26+ months). Conclusions The combination of LUR and IRI is well tolerated, with no unexpected toxicities. Myelosuppression was dose-limiting, but predictable and manageable. The RD is LUR 2.0 mg/m2 on D1 + IRI 75 mg/m2 on D1 and D8 q3w with GCSF. Notable antitumor activity was observed, especially in SCLC, EC, GB and STS. Expansion in these indications is warranted.

8506 Background: Lurbinectedin (L) is a novel anticancer drug that inhibits activated transcription and induces DNA double-strand breaks, leading to apoptosis. Methods: A multicenter phase 2 basket trial assessed the efficacy and safety of L in several cancer types, including small cell lung cancer (SCLC). Primary endpoint was confirmed overall response rate (ORR) by RECIST v.1.1. In the SCLC cohort, a target ORR ≥30% was set. One-hundred and five patients (pts) with ECOG PS 0-2 who had received one prior chemotherapy line were treated with L 3.2 mg/m2 as a 1-hour i.v. infusion on Day 1 q3wk. Results: Median age was 60 years (range, 40-83), 60% were male, ECOG PS 0/1/2 (32%/62%/6%), liver metastasis 41%, history of CNS involvement 3.8%, prior platinum 100%, median chemotherapy-free interval (CTFI): 3.5 (0-16.1) months; prior immunotherapy (IO): 7.6%. Pts received a median of 4 cycles (range, 1-24). Conclusions: L monotherapy is active in second-line SCLC in both resistant and sensitive disease. The acceptable and manageable safety profile is also associated to a convenient treatment administration (Day 1 q3wk). L as second-line treatment in SCLC emerges as a new promising drug for this unmet clinical need. Clinical trial information: NCT02454972. [Table: see text]
