Objectives Both combinations of the PARP inhibitor veliparib plus platinum doublet chemotherapy (CT), and the programmed death receptor-1 (PD-1) inhibitor nivolumab plus CT have demonstrated encouraging efficacy for treatment of non-small cell lung cancer (NSCLC). This phase 1 dose-escalation study (NCT02944396) evaluated the quadruple combination of veliparib with nivolumab and doublet CT in patients with unresectable advanced/metastatic NSCLC. Materials and Methods Patients were enrolled into five dosing cohorts: patients received veliparib 120 mg twice daily (BID) combined with nivolumab 360 mg, carboplatin AUC 6 mg/mL∙min, and paclitaxel 200 mg/m2 (C/PAC) or veliparib 80/120/200/240 mg BID in combination with nivolumab 360 mg, carboplatin AUC 6 mg/mL∙min, and pemetrexed 500 mg/m2 (C/PEM). Primary objective was to identify the recommended phase 2 dose (RP2D) of veliparib + nivolumab + CT. Safety, tolerability, and efficacy of this combination were also assessed. Results Twenty-five patients were enrolled: 6 patients received veliparib 120 mg BID + nivolumab + C/PAC and 19 received veliparib (80–240 mg BID) + nivolumab + C/PEM. No dose-limiting toxicities were reported, and the RP2Ds were veliparib 120 mg BID + nivolumab + C/PAC, and veliparib 240 mg BID + nivolumab + C/PEM. The most common any-grade adverse events (AEs) were fatigue (56%), nausea (52%), and anemia (48%). Grade 3/4 AEs included anemia (32%) and neutropenia (24%), and the most frequent serious AE was malignant neoplasm progression (12%). Veliparib exhibited approximately dose proportional kinetics in the dose range 80–240 mg BID combined with nivolumab and C/PEM, with no effects on pemetrexed pharmacokinetics. Overall, the confirmed objective response rate was 40%, and best overall response was 64%. Conclusion Veliparib combined with nivolumab and platinum doublet CT was tolerated in patients with advanced/metastatic NSCLC, and no evidence of drug–drug interaction was observed. Although preliminary, this quadruple therapy may have promising antitumor activity.

Introduction This open-label, phase 1–2 study evaluated the safety and efficacy of rovalpituzumab tesirine (Rova-T), an antibody-drug conjugate targeting DLL3, plus immune checkpoint inhibitors nivolumab plus or minus ipilimumab in previously treated extensive-stage SCLC (ES SCLC). Methods Patients with histologically or cytologically confirmed, previously treated (two or more lines of therapy) ES SCLC were enrolled into two cohorts. Cohort 1 received 0.3 mg/kg Rova-T (once every 6 wk for two cycles) plus 360 mg nivolumab (two 3-wk cycles beginning on week 4). Cohort 2 received the same dosage of Rova-T as cohort 1 plus 1 mg/kg nivolumab (four 3-wk cycles) and 1 mg/kg ipilimumab (beginning week 4). Both cohorts received 480 mg nivolumab every 4 weeks starting at week 10. Key objectives were to evaluate safety and tolerability and efficacy (per Response Evaluation Criteria in Solid Tumors version 1.1). The response-related results are based on centrally read data. Results A total of 42 patients received therapy: cohort 1, n = 30; cohort 2, n = 12. Overall, 43% received two or more previous lines of therapy. All patients experienced one or more treatment-emergent adverse event (TEAE); 41 patients reported AEs considered related to the study drug by the investigator. The most frequent TEAE was pleural effusion (n = 20, 48%); most common grade greater than or equal to 3 was anemia (n = 9, 21%). Three grade 5 TEAEs considered related to the study drug were reported (cohort 1): pneumonitis (n = 2), acute kidney injury (n = 1). The objective response rate was 30% (12 of 40): cohort 1, 27.6% (8 of 29); cohort 2, 36.4% (4 of 11); all partial responses. Conclusions Despite encouraging antitumor activity in previously treated ES SCLC, combination therapy with Rova-T and nivolumab plus or minus ipilimumab was not well tolerated at the dose levels and administration schedules evaluated.

Small cell lung cancer (SCLC) is a leading cause of cancer death worldwide, with few treatment options. Rovalpituzumab tesirine (Rova-T) is an antibody-drug conjugate that targets delta-like 3 on SCLC cells to deliver a cytotoxic payload directly to tumor cells. In this study, the cardiac safety profile of Rova-T was assessed by evaluating changes in QT interval, electrocardiogram (ECG) waveform, heart rate, and proarrhythmic adverse events (AEs) after treatment with Rova-T in patients with previously treated extensive-stage SCLC. Patients underwent ECG monitoring for 2 weeks after each of 2 i.v. infusions of 0.3 mg/kg Rova-T over 30 minutes, administered 6 weeks apart. Forty-six patients received at least one dose of Rova-T. At the geometric mean Rova-T maximum serum concentration of 7,940 ng/mL, ECG monitoring showed no significant changes in the Fridericia-corrected QT (QTcF) interval; the upper limit of the 2-sided 90% confidence interval did not exceed 10 msec for any time point. There were no clinically significant changes in QRS or PR intervals, ECG waveforms, or heart rate after Rova-T administration. All patients experienced a treatment-emergent AE (TEAE); 78% had a grade ≥ 3 TEAE, 59% had a serious TEAE, and 41% had a cardiac-related TEAE. The TEAEs that might signal proarrhythmia tendencies were uncommon. Confirmed partial responses were observed in 24% of patients. Based on the evaluation of ECG data collected in this study from patients treated with Rova-T at 0.3 mg/kg i.v. administered every 6 weeks, a QTcF effect of clinical concern can be excluded.

Mobocertinib, an oral epidermal growth factor receptor (EGFR) inhibitor targeting EGFR gene mutations, including exon 20 insertions (EGFRex20ins), in non–small cell lung cancer, was evaluated in a phase I/II dose-escalation/expansion trial (ClinicalTrials.gov NCT02716116). Dose escalation identified 160 mg/d as the recommended phase 2 dose and maximum tolerated dose. Among 136 patients treated with 160 mg/d, the most common any-grade treatment-related adverse events (TRAE; >25%) were diarrhea (83%), nausea (43%), rash (33%), and vomiting (26%), with diarrhea (21%) the only grade ≥3 TRAE >5%. Among 28 EGFRex20ins patients treated at 160 mg/d, the investigator-assessed confirmed response rate was 43% (12/28; 95% confidence interval, 24%–63%) with median duration of response of 14 months (5.0–not reached) and median progression-free survival of 7.3 months (4.4–15.6). Mobocertinib demonstrated antitumor activity in patients with diverse EGFRex20ins variants with a safety profile consistent with other EGFR inhibitors. Significance: No oral EGFR-targeted therapies are currently approved for patients with EGFRex20ins NSCLC. Mobocertinib demonstrated antitumor activity with manageable toxicity in patients with advanced EGFRex20ins NSCLC in this study, supporting additional development of mobocertinib in this patient population.

Purpose: Multisite stereotactic body radiotherapy followed by pembrolizumab (SBRT+P) has demonstrated safety in advanced solid tumors (ASTs). However, no studies have examined the relationships between irradiated tumor response, SBRT-induced tumor gene expression, and overall survival (OS). Patients and Methods: Patients with AST received SBRT (30–50 Gy in 3–5 fractions) to two to four metastases followed by pembrolizumab (200 mg i.v. every 3 weeks). SBRT was prescribed to a maximum tumor volume of 65 mL. Small metastases received the complete prescribed coverage (complete-Rx), while larger metastases received partial coverage (partial-Rx). Treated metastasis control (TMC) was defined as a lack of progression for an irradiated metastasis. Landmark analysis was used to assess the relationship between TMC and OS. Thirty-five biopsies were obtained from 24 patients: 19 pre-SBRT and 16 post-SBRT (11 matched) prior to pembrolizumab and were analyzed via RNA microarray. Results: Sixty-eight patients (139 metastases) were enrolled with a median follow-up of 10.4 months. One-year TMC was 89.5% with no difference between complete-Rx or partial-Rx. On multivariable analysis, TMC was independently associated with a reduced risk for death (HR, 0.36; 95% confidence interval, 0.17–0.75; P = 0.006). SBRT increased expression of innate and adaptive immune genes and concomitantly decreased expression of cell cycle and DNA repair genes in the irradiated tumors. Elevated post-SBRT expression of DNASE1 correlated with increased expression of cytolytic T-cell genes and irradiated tumor response. Conclusions: In the context of SBRT+P, TMC independently correlates with OS. SBRT impacts intratumoral immune gene expression associated with TMC. Randomized trials are needed to validate these findings.

Objective To evaluate the findings of magnetic resonance imaging (MRI) of the ipsilateral hip(s) as part of the workup of men with chronic orchialgia (CO). Methods Following IRB approval, a retrospective chart review was performed from a single surgeon database of all men with a diagnosis of CO from June 2018 to October 2019 who underwent subsequent hip MRI evaluation. Results Ten men were identified. Median age was 51 years and median duration of pain was 10 months. MRI was obtained after testis pathology was ruled out. Pain was noted in the groin (100%) and hip (50%). Hip MRI identified overt labral tears in 8 men (10/12 hips evaluated, 83%) and labral fraying in the remaining 2 (16.7%). Standard plain film radiography was performed in 6 men prior to MRI, all of which were negative. Following MRI, 5 men underwent hip injection with steroid and local analgesic with lasting resolution (2 men) or significant improvement in pain (2 men; 80%, follow-up 3-15 months). Two men had complete resolution of pain with 8 weeks of physical therapy. Conclusion Hip MRI has a high rate of diagnosis of labral tear in appropriately selected men referred to the urologist for CO. Identification of orthopedic pathology may avoid unnecessary antibiotics, opiates, or urological surgery. Referrals to orthopedics and/or physical therapy for intervention may lead to resolution of pain.

Introduction Although chemoradiotherapy (CRT) is the standard of care for patients with unresectable stage III non–small-cell lung cancer (LA-NSCLC), most patients relapse. Tecemotide is a MUC1 antigen-specific cancer immunotherapy vaccine. Bevacizumab improves survival in advanced nonsquamous (NS)-NSCLC and has a role in immune modulation. This phase II trial tested the combination of tecemotide and bevacizumab following CRT in patients with LA-NSCLC. Patients and Methods Subjects with stage III NS-NSCLC suitable for CRT received carboplatin/paclitaxel weekly + 66 Gy followed by 2 cycles of consolidation carboplatin/paclitaxel ≤ 4 weeks of completion of CRT (Step 1). Patients with partial response/stable disease after consolidation therapy were registered onto step 2, which was 6 weekly tecemotide injections followed by every 6 weekly injections and bevacizumab every 3 weeks for up to 34 doses. The primary endpoint was to determine the safety of this regimen. Results Seventy patients were enrolled; 68 patients (median age, 63 years; 56% male; 57% stage IIIA) initiated therapy, but only 39 patients completed CRT and consolidation therapy per protocol, primarily owing to disease progression or toxicity. Thirty-three patients (median age, 61 years; 58% male; 61% stage IIIA) were registered to step 2 (tecemotide + bevacizumab). The median number of step 2 cycles received was 11 (range, 2-25). Step 2 worst toxicity included grade 3, N = 9; grade 4, N = 1; and grade 5, N = 1. Grade 5 toxicity in step 2 was esophageal perforation attributed to bevacizumab. Among the treated and eligible patients (n = 32) who were treated on step 2, the median overall survival was 42.7 months (95% confidence interval, 21.7-63.3 months), and the median progression-free survival was 14.9 months (95% confidence interval, 11.0-20.9 months) from step 1 registration. Conclusions This cooperative group trial met its endpoint, demonstrating tolerability of bevacizumab + tecemotide after CRT and consolidation. In this selected group of patients, the median progression-free survival and overall survival are encouraging. Given that consolidation immunotherapy is now a standard of care following CRT in patients with LA-NSCLC, these results support a role for continued investigation of antiangiogenic and immunotherapy combinations in LA-NSCLC.

BackgroundThe selective TRK inhibitor larotrectinib was approved for paediatric and adult patients with advanced TRK fusion-positive solid tumours based on a primary analysis set of 55 patients. The aim of our analysis was to explore the efficacy and long-term safety of larotrectinib in a larger population of patients with TRK fusion-positive solid tumours.MethodsPatients were enrolled and treated in a phase 1 adult, a phase 1/2 paediatric, or a phase 2 adolescent and adult trial. Some eligibility criteria differed between these studies. For this pooled analysis, eligible patients were aged 1 month or older, with a locally advanced or metastatic non-CNS primary, TRK fusion-positive solid tumour, who had received standard therapy previously if available. This analysis set includes the 55 patients on which approval of larotrectinib was based. Larotrectinib was administered orally (capsule or liquid formulation), on a continuous 28-day schedule, to adults mostly at a dose of 100 mg twice daily, and to paediatric patients mostly at a dose of 100 mg/m2 (maximum of 100 mg) twice daily. The primary endpoint was objective response as assessed by local investigators in an intention-to-treat analysis. Contributing trials are registered with ClinicalTrials.gov, NCT02122913 (active not recruiting), NCT02637687 (recruiting), and NCT02576431 (recruiting).FindingsBetween May 1, 2014, and Feb 19, 2019, 159 patients with TRK fusion-positive cancer were enrolled and treated with larotrectinib. Ages ranged from less than 1 month to 84 years. The proportion of patients with an objective response according to investigator assessment was 121 (79%, 95% CI 72-85) of 153 evaluable patients, with 24 (16%) having complete responses. In a safety population of 260 patients treated regardless of TRK fusion status, the most common grade 3 or 4 larotrectinib-related adverse events were increased alanine aminotransferase (eight [3%] of 260 patients), anaemia (six, 2%), and decreased neutrophil count (five [2%]). The most common larotrectinib-related serious adverse events were increased alanine aminotransferase (two [

Background: Black patients have been historically underrepresented in studies investigating molecular patterns in non-small cell lung cancer (NSCLC). We aimed to investigate differences in actionable mutations among patients at our urban, diverse medical center. Results: 146 patients were included (59 black, 76 white, 7 Asian, 3 Hispanic, 1 mixed). 35 patients had a targetable mutation. Seven black patients (11.8%) had a targetable mutation compared to 28 non-black patients (32.2%, p = 0.005). 15 black patients had PD-L1 expression ≥50% compared to 19 non-black (25.4% vs 21.8%, p = 0.69). Black patients had a higher TMB compared to non-black (15.3 mutations/Mb compared to 11.5 mutations/Mb, p = 0.001). In a multivariate analysis, TMB was driven by smoking (p < 0.01), without any additive interaction in black patients who smoke (p = 0.8). Conclusion: NSCLC tumors from black patients had a higher TMB and were less likely to carry a targetable mutation. The higher TMB seen was driven by a higher prevalence of smoking among black patients in our study, which may not reflect nationwide trends. Our results serve as a proof of concept that differences in molecular markers exist between black and non-black patients, and that these differences may impact the treatment options available to black patients. Methods: Retrospective chart review of patients with a diagnosis of NSCLC who underwent both PD-L1 testing and massively parallel sequencing (UCM-OncoPlus) was conducted. We examined whether high PD-L1 expression, tumor mutational burden (TMB), and presence of targetable mutations (EGFR, BRAF, ERBB2, RET or ALK translocations, ROS1 rearrangements) occur at different frequencies in tumors from black patients compared to non-black patients.

Objectives To assess the safety and efficacy of atezolizumab and docetaxel in patients with and without a history of asymptomatic, treated brain metastases in the phase III OAK trial. Materials and methods Patients received 1200 mg atezolizumab or 75 mg/m2 docetaxel every 3 weeks until unacceptable toxicity, disease progression, or loss of clinical atezolizumab benefit. Patients with asymptomatic, treated supratentorial metastases were eligible. Patients had brain scans before enrollment; follow-up brain scans and treatment were required when clinically indicated. Results Approximately 14% of patients in each arm had a history of asymptomatic, treated brain metastases (61/425 in the atezolizumab arm and 62/425 in the docetaxel arm). Fewer treatment-related adverse events (AEs), serious AEs, and treatment-related neurologic AEs were reported with atezolizumab than with docetaxel, regardless of history of asymptomatic, treated brain metastases. In patients with a history of asymptomatic, treated brain metastases, median overall survival (OS) was longer with atezolizumab than with docetaxel (16.0 vs 11.9 months; hazard ratio = 0.74; 95% CI: 0.49–1.13). Median OS was also longer with atezolizumab in patients without a history of asymptomatic, treated brain metastases (13.2 vs 9.3 months; hazard ratio = 0.74; 95% CI: 0.63–0.88). Landmark analyses showed that patients with a history of asymptomatic, treated brain metastases had a lower probability of developing new symptomatic brain lesions with atezolizumab vs docetaxel at 6–24 months. Patients without a history had a lower probability with atezolizumab at 18–24+ months. Conclusion Atezolizumab had an acceptable neurologic safety profile, showed a trend toward an OS benefit, and led to a prolonged time to radiographic identification of new symptomatic brain lesions compared with docetaxel in patients who had a history of asymptomatic, treated brain metastases. Clinicaltrials.gov registration number: NCT02008227.

Immune checkpoint blockade (ICB) improves outcomes in non-small cell lung cancer (NSCLC) though most patients progress. There are limited data regarding molecular predictors of progression. In particular, there is controversy regarding the role of CDKN2A loss-of-function (LOF) in ICB resistance. We analyzed 139 consecutive patients with advanced NSCLC who underwent NGS prior to ICB initiation to explore the association of CDKN2A LOF with clinical outcomes. 73% were PD-L1 positive (≥ 1%). 48% exhibited high TMB (≥ 10 mutations/megabase). CDKN2A LOF was present in 26% of patients and was associated with inferior PFS (multivariate hazard ratio [MVA-HR] 1.66, 95% CI 1.02–2.63, p = 0.041) and OS (MVA-HR 2.08, 95% CI 1.21–3.49, p = 0.0087) when compared to wild-type (WT) patients. These findings held in patients with high TMB (median OS, LOF vs. WT 10.5 vs. 22.3 months; p = 0.069) and PD-L1 ≥ 50% (median OS, LOF vs. WT 11.1 vs. 24.2 months; p = 0.020), as well as in an independent dataset. CDKN2A LOF vs. WT tumors were twice as likely to experience disease progression following ICB (46% vs. 21%; p = 0.021). CDKN2A LOF negatively impacts clinical outcomes in advanced NSCLC treated with ICB, even in high PD-L1 and high TMB tumors. This novel finding should be prospectively validated and presents a potential therapeutic target.

Previous studies have evaluated stereotactic body radiotherapy (SBRT) in oligometastatic patients with NSCLC, including multimodality treatment with anti-programmed cell death protein-1 monotherapy. Questions remain regarding the timing of SBRT and immunotherapy, safety with dual checkpoint blockade, and the utility in widely metastatic patients. This randomized phase 1 trial combined nivolumab and ipilimumab with sequential or concurrent multisite SBRT in patients with stage IV NSCLC to evaluate safety and obtain preliminary activity data.Treatment-naive patients with metastatic NSCLC were randomized to concurrent (SBRT with immunotherapy) or sequential (SBRT followed by immunotherapy) treatment. A maximum of four treatment fields received SBRT. Nivolumab and ipilimumab were continued until clinical progression, development of toxicity, or after 2 years. Dose-limiting toxicity was defined as greater than or equal to grade 3 toxicity to the relevant organ system attributed to SBRT and immunotherapy occuring within 3 months.A total of 37 patients were assessable. No dose-limiting toxicity occurred in the concurrent cohort (n = 18). The sequential cohort required a dose reduction in the central lung group owing to two grade 4 pneumonitis events (2 of 19). Overall best response was as follows: 5.4% (2 of 37) complete response, 40.5% (15 of 37) partial response, 16.2% (6 of 37) stable disease, and 37.8% (14 of 37) progressive disease. Median progression-free survival was 5.8 months (95% confidence interval: 3.6-11.4 mo), with median follow-up of 17.0 months. Median overall survival was not reached.Concurrent nivolumab, ipilimumab, and SBRT were not more toxic than sequential therapy, and multisite SBRT was well tolerated in widely metastatic patients. Multimodality therapy resulted in durable metastasis control and encouraging early overall survival.

Background Brain metastases (BMs) are reported in 20–40% patients with METex14 skipping NSCLC. Tepotinib, a highly selective MET inhibitor, has demonstrated an objective response rate (ORR) of 45% and median duration of response (mDOR) of 11.1 months, in METex14 skipping NSCLC patients in Cohort A of the Phase II VISION study. Here, we report the intracranial activity of tepotinib in Cohort A. Methods Patients received oral tepotinib 500 mg QD. Study eligibility allowed for patients with BM (asymptomatic and symptomatic/stable). Primary endpoint: systemic objective response (RECIST v1.1); subgroup analysis in patients with BM (RECIST v1.1) was predefined. An ad hoc retrospective analysis of brain lesions (by CT/MRI) was conducted by an IRC using Response Assessment in Neuro-Oncology Brain Metastases (RANO-BM) criteria. Responses were determined in patients with ≥1 evaluable post-baseline tumor assessment. For non-measurable lesions (enhancing and non-enhancing non-target lesions [NTL]), disease control in the brain was defined as non-complete response/non-progressive disease. Data cut-off: July 1, 2020. Results Twenty-three patients had baseline BM. Systemic efficacy in patients with BM (ORR 47.8% [95% CI: 26.8, 69.4]; mDOR 9.5 months [95% CI: 5.5, not estimable]) was consistent with the overall population. Fifteen patients were evaluable by RANO-BM; 12 received prior radiotherapy for BM (median 6.4 weeks before treatment). Systemic best objective responses (BORs) were partial response (PR, n=9), stable disease (SD, n=3), and progressive disease (PD; n=3). Of seven patients with measurable CNS disease (all of whom received prior radiotherapy), intracranial BORs were PR (n=5), SD (n=1), and PD (n=1). For patients with NTL only (n=8), one had PD, and seven achieved intracranial disease control with three patients achieving CR of the enhancing NTL. Conclusions Tepotinib demonstrated intracranial activity in patients with METex14 skipping NSCLC with BM. Prospective evaluation of intracranial activity in VISION Cohort C is ongoing.

Objective To examine voluntary reports in the Food & Drug Administration (FDA) Manufacturer and User Facility Device Experience (MAUDE) database, categorize complications and assign device-related causality with transurethral resection of the prostate (TURP), prostatic urethral lift (PUL), and transurethral water vapor therapy (TWVT). Methods A review was performed using the terms “Urolift,” “Rezum,” and “transurethral resection of the prostate” between 01/01/2015 and 12/31/2019. Duplicate and incomplete reports were excluded. The Gupta system was used to report complications and device related causality. 1 Pearson's Chi-square analysis was performed to compare minor (Level 1) versus major (Levels 2-4) complications. Results A total of 548 events were examined. After removal of duplicates (n = 60), irrelevant reports (n=65), and incomplete information (n = 14), we included 409 events (74.6%). Of the 409 events, 214 were for TURP, 112 for TWVT, and 83 for PUL. In aggregate, 39.4% of events were minor/Level 1 (n=161/409). The proportion of subjects with Level 2-4 complications versus Level 1 complications was significantly higher for PUL than TURP or TWVT [X2 (2, N = 408) = 41.4023, P Conclusion Device malfunction was noted in all groups and 39.4% of these were minor (Level 1). However, the majority of PUL reports noted a Level 3 or 4 complication (50.6%, 42/83), primarily bleeding related. Previous studies have not revealed significant risk of bleeding and suggests a discrepancy between study data and real-world experience that may alter patient counseling practices.

Aim Gunshot wounds (GSW) to the penis represent a rare type of traumatic injury in the civilian United States population. Although small, single-center studies have reported results of care for these types of injured patients, no national analyses have examined this group. Methods A cohort of patients with GSW to the penis was identified using the 2017 American College of Surgeons Trauma Quality Programs database, a comprehensive national database of 753 accredited trauma centers. Results Gunshot wounds to the penis occurred in 722 patients, which represents 1.7% of all GSW patients (n = 41,017). Gunshot wounds from altercations with law enforcement or accidental discharge of a firearm were rare; the vast majority (n = 655, 90.7%) occurred as a result of assault, intentional self-harm, attempted suicide, or attempted homicide. Patients with a major concomitant non-genitourinary injury comprised 119 (16.5%) patients of the cohort. Most patients (n = 499, 69.1%) underwent a genitourinary procedure during their trauma admission. Penile salvage was successful in most cases, with only 13 (1.8%) patients requiring completion penectomy. Most patients (87.8%) required admission with a median length of stay of 49.8 h. Most patients were treated at the initial trauma center without requiring transfer to another center, and complications during admission were rare. Conclusions This analysis, the first national examination of care of patients with GSW to the penis, reveals overall favorable outcomes. Admission and surgical intervention were required in most patients, but penectomy was rare and length of stay was generally short. These results will guide resource utilization and quality improvement efforts in this patient cohort.

OBJECTIVES We hypothesize that men with diabetes mellitus whose inflatable penile prosthesis (IPP) implantation is delayed for unacceptably high hemoglobin A1c (HbA1c) will have durable improvements in their glycemic control after achieving acceptable HbA1c levels for surgery. METHODS Per institutional protocol, an A1c

The RET receptor tyrosine kinase proto-oncogene is activated by somatic or germline mutations in a majority of medullary thyroid cancers (MTC). However, treatment of MTC has been challenging due to the lack of effective and tolerable RET-specific therapy, thus testing tumors for the presence of somatic RET mutation has not been warranted. In a first-in-human, phase 1/2 clinical trial (LIBRETTO-001, NCT03157128), selpercatinib (LOXO-292), an investigational, highly selective, potent small molecule RET kinase inhibitor, demonstrated significant and durable anti-tumor activity in patients with advanced RET-mutant MTC or with diverse RET fusion-positive cancers (1). Among the primary analysis set of patients with RET-mutant MTC previously treated with cabozantinib and/or vandetanib (N=55), the investigator-assessed objective response rate (ORR) per RECIST 1.1 was 56% (95% CI 42.3-69.7, n=31/55). Duration of response was not reached with a 10.6-months median follow-up (data cutoff date 17-Jun-2019). Here, we evaluated investigator-assessed ORR per RECIST 1.1 and clinical benefit rate (CBR) in this previously treated patient population by RET alteration and by germline or somatic testing used for enrollment. The ORR remained consistent across subgroups with RET M918T (49%, 95% CI 30.8-66.5, n=16/33), V804M/L gatekeeper mutations (60%, 95% CI 14.7-94.7, n=3/5), extracellular cysteine mutations (43%, 95% CI 9.9-81.6, n=3/7), other mutations (90%, 95% CI 55.5-99.7, n=9/10), and germline (50%, 95% CI 6.8-93.2, n=2/4) or somatic (57%, 95% CI 42.2-70.7, n=29/51) testing. The CBR, defined as the proportion of patients with best overall response of confirmed complete response, confirmed or unconfirmed partial response, or stable disease lasting 16 weeks or more, in this patient set was 87% (95% CI 75.5-94.7, n=48/55). The CBR remained consistent across subgroups with RET M918T (88%, 95% CI 71.8-96.6, n=29/33), V804M/L gatekeeper mutations (80%, 95% CI 28.4-99.5, n=4/5), extracellular cysteine mutations (71%, 95% CI 29.0-96.3, n=5/7), other mutations (100%, 95% CI 69.2-100.0, n=10/10), and germline (75%, 95% CI 19.4-99.4, n=3/4) or somatic (88%, 95% CI 76.1-95.6, n=45/51) testing. The primary technologies used to identify RET alterations were tumor next-generation sequencing (n=43) and polymerase chain reaction (n=9). As previously reported, selpercatinib was well tolerated with an acceptable safety profile (1). These results indicate broad anti-tumor activity for selpercatinib in patients with RET-mutant MTC irrespective of the specific RET mutation, and support implementation of RET mutation testing for patients with advanced MTC, including somatic testing, to identify patients who may benefit from selpercatinib.

Introduction The artificial urinary sphincter (AUS) has long been regarded as the gold standard for surgical correction of male stress urinary incontinence (SUI). Despite impressive rates of initial success for restoration of continence, durability may wane to the point of considering revision surgery. Aim To provide a review of existing data as well as personal experience regarding patient selection, surgical technique, and postoperative troubleshooting for the AUS. Methods A systematic review of the peer-reviewed literature was performed to identify relevant and contemporary articles regarding perioperative and long-term management of the AUS. Additional input is presented based on clinical experience of the senior author. Main Outcome Measure The main outcome measures are durability, patient satisfaction, mechanical failure, and urethral erosion. Results In addition to a thorough history and examination, preoperative screening should include office cystoscopy to rule out bladder neck contracture in patients with a history of radical prostatectomy. Perineal cuff placement appears superior to alternative approaches. Prior radiation and use of the 3.5-cm cuff are risk factors for future erosion. Newer findings suggest that subsequent recurrence of SUI may be due to restrictive encapsulation, rather than true atrophy, with implications for revision surgery. Conclusion The AUS remains an excellent option for surgical correction of moderate to severe male SUI. Detailed preoperative evaluation and patient selection are critical. The challenge of downstream recurrent SUI after AUS can be effectively managed for most patients with a structured approach. Chouhan JD, Terlecki RP.

Purpose To evaluate the clinical outcome of patients with non–small-cell lung cancer treated by targeting low variant allelic frequency (VAF) driver mutations identified through cell-free DNA (cfDNA) next-generation sequencing (NGS). Detection of driver mutations in cancer is critically important in the age of targeted therapy, where both tumor-based as well as cfDNA sequencing methods have been used for therapeutic decision making. We hypothesized that VAF should not be predictive of response and that low VAF alterations detected by cfDNA NGS can respond to targeted therapy. Patients and Methods A multicenter retrospective case review was performed to identify patients with non–small-cell lung cancer who received targeted molecular therapy on the basis of findings of low VAF alterations in cfDNA NGS. Mutations at low VAF were defined as < 0.2% mutated cfDNA molecules in a background of wild-type cfDNA. Results One hundred seventy-two patients underwent cfDNA NGS testing. Of the 172 patients, 12 were identified as having low VAF driver alterations and were considered for targeted therapy. The median progression-free survival (PFS) for all patients was 52 weeks (range, 17 to 88 weeks). For patients with EGFR exon 19 deletion (n = 7), the median PFS was 52 weeks (range, 17 to 60.5 weeks). For patients with EML4-ALK fusions (n = 3), the median PFS was 60 weeks (range, 18 to 88 weeks). The median overall survival for all patients after diagnosis was 57.6 weeks. Conclusion Targeted treatment response for driver mutations detected by cfDNA may be independent of VAF, even in relation to other higher VAF aberrations in plasma, and directly dependent on the underlying disease biology and ability to treat the patient with appropriate targeted therapy.

Purpose/Objective(s) Combination SBRT and immune checkpoint inhibition is safe and efficacious for metastatic NSCLC. It is unknown whether the site of metastatic disease at diagnosis or SBRT response can be used as predictors of PFS or OS. We report follow-up from a prospective phase I clinical trial examining predictors of OS and PFS based on initial metastatic tumor disease location, as well as SBRT response. Materials/Methods Thirty-seven patients with treatment-naive metastatic NSCLC were reviewed. Patients received SBRT to doses of 30-50 Gy in 3-5 fractions to 1-6 metastases, as well as concurrent (immunotherapy with SBRT) or sequential (immunotherapy after completion of SBRT) nivolumab/ipilimumab on a phase I clinical trial at a single institution. All metastatic lesions were evaluated and the sites of initial disease, including liver, bone, or thoracic only metastases, were evaluated to determine if those sites influenced OS or PFS. Treated metastases control (TMC) was defined as lack of progression for irradiated metastases. Landmark analysis was used to assess correlation of TMC and OS. The Kaplan-Meier method was used to analyze OS and PFS. Results Thirty-seven patients with 120 evaluable metastases were enrolled with a median follow-up of 17.0 months. Patients who had liver metastases at baseline (n = 8) were found to have a worse PFS (log-rank P = 0.048), but no difference in OS (log-rank P = 0.243) when compared to patients who did not have liver metastases at baseline (n = 29). There was a trend toward significance for better PFS in patients who had thoracic only metastases at baseline (n = 6) compared to patients that had extra-thoracic metastases (n = 31) at baseline (Gehan-Breslow-Wilcoxon P = 0.061); however, there was no difference in OS. There was no statistically significant difference in PFS or OS for patients with bone metastases (n = 9) at baseline compared to patients who did not have bone metastases at baseline (n = 28). One- and two-year TMC were 93.8% and 91.7%, respectively. TMC corresponded to better OS (log-rank P = 0.040). Conclusion Liver metastases present at diagnosis in metastatic NSCLC correlate with worse PFS. Treated metastases control rates also correlate with OS. These metrics may help predict outcomes and inform whether additional aggressive therapy is required for patients with metastatic NSCLC.

Clinicians come across cases of palatal swellings that present with ambiguous features. They may vary in their etiology from numerous infectious and noninfectious causes to a wide array of neoplasms. Accurate diagnosis of such lesions is vital for their prompt and precise management. Rhinoscleroma (RS), as its name suggests, is a persistent, specific, granulomatous disease that results in sclerosis of the affected organ – most frequently the nose. Although its occurrence in the adjacent sites has been reported, the clinical findings did not offer much deviation from the expected. Reported here is a case of RS involving the palate which not only detoured from its usual site and course of spread but also gave off a confusing façade in terms of its clinical presentation.

Introduction The sequence of chemotherapy and pembrolizumab may affect antitumor immune response and efficacy of immunotherapy. Methods This multicenter, randomized, phase 2 trial was designed to evaluate the efficacy of two sequences of chemotherapy and pembrolizumab in patients with stage 4 NSCLC. Both arms were considered investigational, and the study used a “pick a winner” design. The primary end point was objective response rate by independent radiologic review after eight cycles (24 wk). Patients were randomized 1:1 to arm A (chemotherapy for four cycles followed by pembrolizumab for four cycles) or arm B (pembrolizumab for four cycles followed by chemotherapy for four cycles). Patients in both arms without disease progression after the initial eight cycles continued pembrolizumab until disease progression, unacceptable toxicity, or a maximum of 2 years. Results From March 2016 to July 2018, a total of 90 eligible patients were randomized (43 patients to arm A and 47 patients to arm B). The objective response rate at 24 weeks in arms A and B was 39.5 % (95 % confidence interval [CI]: 24.9%–54.1 %) and 40.4 % (95 % CI: 26.4%–54.5 %), respectively (p = 0.93). The progression-free survival in arms A and B was as follows: hazard ratio of B versus A equals to 1.06, 95 % CI: 0.68–1.66, p value equals to 0.84, and median progression-free survival of 5.8 months and 4 months, respectively. The overall survival was as follows: hazard ratio of B versus A equals to 1.04, 95 % CI: 0.63–1.74, p value equals to 0.85, and median overall survival of 15.5 months and 14 months, respectively. Conclusions Additional evaluation of either sequence in a phase 3 trial is not warranted.

Luke, email: jluke@medicine.bsd.uchicago.edu Keywords: non-small cell lung cancer; anti-PD-1/PD-L1 therapy; acquired resistance; immunotherapy; innate resistance Received: September 04, 2017 Accepted: December 08, 2017 Published: December 15, 2017 ABSTRACT Hypothesis: The majority of non-small cell lung cancer (NSCLC) patients treated with anti-PD-1/PD-L1 therapy develop either innate or acquired resistance. Across tumor types, the "T cell-inflamed" tumor microenvironment correlates with clinical response to immunotherapy. We hypothesize that clinical characteristics may be predictive of resistance and that "T cell-inflamed" NSCLC tumors can be identified by gene expression profiling. Results: Of 93 patients, 36 (38.7%) had innate resistance and 57 (61.3%) had initial benefit to immunotherapy. Innate resistance was associated with non-smokers ( p = 0.013), more involved disease sites ( p = 0.011), more prior therapy ( p = 0.001), and a lower albumin level ( p = 0.014). Among patients with initial benefit, factors associated with subsequent progression-free survival included higher Karnofsky Performance Status (KPS) ( p = 0.004) and lower depth of response to anti-PD-1 therapy ( p = 0.003). A "T cell-inflamed" microenvironment was identified in 42% of TCGA adenocarcinoma samples versus 21.0% of squamous cell. Discussion: Specific clinical characteristics appear to be predictive of either innate or acquired resistance to anti-PD-1/PD-L1 therapy. A "T cell-inflamed" tumor was more common in adenocarcinoma than squamous histology. Methods: A retrospective review of NSCLC patients treated with anti-PD-1/PD-L1 monotherapy. Patients with innate resistance to anti-PD-1/PD-L1 therapy (defined as progression at first CT evaluation) were compared to patients with initial clinical benefit. Among those with initial clinical benefit, we identified prognostic factors for time to progression (acquired resistance) or death. To further corroborate our findings on limited numbers, immune gene expression profiling of all NSCLC samples from the TCGA database was also pursued.

Summary Background Adjuvant chemotherapy for resected early-stage non-small-cell lung cancer (NSCLC) provides a modest survival benefit. Bevacizumab, a monoclonal antibody directed against VEGF, improves outcomes when added to platinum-based chemotherapy in advanced-stage non-squamous NSCLC. We aimed to evaluate the addition of bevacizumab to adjuvant chemotherapy in early-stage resected NSCLC. Methods We did an open-label, randomised, phase 3 trial of adult patients (aged ≥18 years) with an Eastern Cooperative Oncology Group performance status of 0 or 1 and who had completely resected stage IB (≥4 cm) to IIIA (defined by the American Joint Committee on Cancer 6th edition) NSCLC. We enrolled patients from across the US National Clinical Trials Network, including patients from the Eastern Cooperative Oncology Group–American College of Radiology Imaging Network (ECOG-ACRIN) affiliates in Europe and from the Canadian Cancer Trials Group, within 6–12 weeks of surgery. The chemotherapy regimen for each patient was selected before randomisation and administered intravenously; it consisted of four 21-day cycles of cisplatin (75 mg/m 2 on day 1 in all regimens) in combination with investigator's choice of vinorelbine (30 mg/m 2 on days 1 and 8), docetaxel (75 mg/m 2 on day 1), gemcitabine (1200 mg/m 2 on days 1 and 8), or pemetrexed (500 mg/m 2 on day 1). Patients in the bevacizumab group received bevacizumab 15 mg/kg intravenously every 21 days starting with cycle 1 of chemotherapy and continuing for 1 year. We randomly allocated patients (1:1) to group A (chemotherapy alone) or group B (chemotherapy plus bevacizumab), centrally, using permuted blocks sizes and stratified by chemotherapy regimen, stage of disease, histology, and sex. No one was masked to treatment assignment, except the Data Safety and Monitoring Committee. The primary endpoint was overall survival, analysed by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00324805. Findings Between June 1, 2007, and Sept 20, 2013, 1501 patients were enrolled and randomly assigned to the two treatment groups: 749 to group A (chemotherapy alone) and 752 to group B (chemotherapy plus bevacizumab). 383 (26%) of 1458 patients (with complete staging information) had stage IB, 636 (44%) had stage II, and 439 (30%) had stage IIIA disease (stage of disease data were missing for 43 patients). Squamous cell histology was reported for 422 (28%) of 1501 patients. All four cisplatin-based chemotherapy regimens were used: 377 (25%) patients received vinorelbine, 343 (23%) received docetaxel, 283 (19%) received gemcitabine, and 497 (33%) received pemetrexed. At a median follow-up of 50·3 months (IQR 32·9–68·0), the estimated median overall survival in group A has not been reached, and in group B was 85·8 months (95% CI 74·9 to not reached); hazard ratio (group B vs group A) 0·99 (95% CI 0·82–1·19; p=0·90). Grade 3–5 toxicities of note (all attributions) that were reported more frequently in group B (the bevacizumab group) than in group A (chemotherapy alone) were overall worst grade (ie, all grade 3–5 toxicities; 496 [67%] of 738 in group A vs 610 [83%] of 735 in group B), hypertension (60 [8%] vs 219 [30%]), and neutropenia (241 [33%] vs 275 [37%]). The number of deaths on treatment did not differ between the groups (15 deaths in group A vs 19 in group B). Of these deaths, three in group A and ten in group B were considered at least possibly related to treatment. Interpretation Addition of bevacizumab to adjuvant chemotherapy did not improve overall survival for patients with surgically resected early-stage NSCLC. Bevacizumab does not have a role in this setting and should not be considered as an adjuvant therapy for patients with resected early-stage NSCLC.

Lung cancer care is rapidly changing with advances in genomic testing, the development of next-generation targeted kinase inhibitors, and the continued broad study of immunotherapy in new settings and potential combinations. The International Association for the Study of Lung Cancer and the Journal of Thoracic Oncology publish this annual update to help readers keep pace with these important developments. Experts in thoracic cancer and care provide focused updates across multiple areas, including prevention and early detection, molecular diagnostics, pathology and staging, surgery, adjuvant therapy, radiotherapy, molecular targeted therapy, and immunotherapy for NSCLC, SCLC, and mesothelioma. Quality and value of care and perspectives on the future of lung cancer research and treatment have also been included in this concise review.

Background The penile prosthesis has been used for men with erectile dysfunction for nearly 5 decades. Although many articles examine various outcome measures, wide variability exists in the quality of these studies. Aim We sought to critically evaluate the most referenced literature related to penile prosthesis outcomes over the last 10 years. Methods A PubMed search of the indexed English literature was performed using the search terms “prospective,” “penile prosthesis,” and “outcomes”, and all relevant publications from 2009 to 2019 were reviewed. In addition, we performed a Google Scholar search for the same interval using the search term “penile prosthesis outcomes” to evaluate manuscripts which have been most commonly cited. The most heavily cited manuscripts were sorted for relevancy using Google's internal algorithm, and then, the articles were reviewed by the authorship team for appropriateness of the subject matter. Articles with less than 10 citations were excluded. We used the Oxford Center for Evidence-Based Medicine Criteria as part of our evaluation of the published data involving independent research, as opposed to review articles summarizing previously published findings. Results We evaluated the most-cited literature of the past decade relevant to penile prosthesis outcomes and reported the major findings in regards to infection, erosion, extrusion, device reliability, and satisfaction (both the patient and partner). The majority of these studies are retrospective in nature. Clinical Implications From our review of the most commonly cited studies, there was no high-level evidence published in this area within the last 10 years. There are multiple barriers to producing these types of studies in the evaluation of penile prosthesis outcomes. Strengths & Limitations Using the most commonly cited articles allows us to understand the data that are being cited in other new publications. Focusing on the most cited articles on penile prosthesis outcomes in the last 10 years is a limitation as there have been many more studies published in this area. Conclusion While many studies have examined penile prosthesis outcomes, most of the heavily cited literature consists of low-level evidence. Higher quality research is necessary to better assess penile prosthesis outcomes.

To provide an overview of the state of tissue engineering relative to male erectile tissue and the implications for treatment of penile pathology. A PubMed review of the relevant peer-reviewed literature pertaining to engineering of penile tissues was performed. There are multiple pathologies that threaten form and/or function of the penis. Management of disease rarely offers a path to true restoration. Historical efforts to correct structural defects have largely relied on synthetic materials, commercially prepared allograft or xenograft constructs, or autologous tissue substitutes. These approaches have traditionally suffered from less-than-optimal clinical outcomes and degrees of patient morbidity that may be preventable. Prior work in tissue engineering of corpora cavernosa has demonstrated the ability to produce functional tissue in small and large animal models. A human clinical trial is currently underway. Varied conditions pathologically affecting the penis warrant development of more sophisticated tissue-based solutions. Animal models have demonstrated efficacy in restoring functional corpora cavernosa, and upcoming clinical trials will serve to determine safety and efficacy in humans.

Introduction: Selpercatinib, a first-in-class highly selective and potent RET kinase inhibitor, is approved in multiple countries for the treatment of RET fusion-positive lung or thyroid cancers. RET fusions are also implicated in the pathogenesis of other cancers. Selpercatinib's efficacy and safety were thus explored in patients (pts) with RET fusion-positive non-lung/non-thyroid cancers in a global, multicenter, registrational trial. Methods: Adults with locally advanced or metastatic RET fusion-positive non-lung/non-thyroid solid tumors enrolled in the phase 1/2 LIBRETTO-001 trial (NCT03157128) were included in this analysis (data cut-off: 19 March 2021). Following dose escalation, pts received the recommended dose of 160 mg orally, twice daily. Pts enrolled long enough to allow 6-month follow-up from their first dose comprised the efficacy-evaluable population. Response was assessed (RECIST 1.1) by investigators. The primary endpoint was objective response rate (ORR). Secondary endpoints included duration of response (DoR), time to response, and safety. Results: Thirty-two pts with RET fusion-positive non-lung/non-thyroid cancers included 12 unique tumor types: 9 pancreatic, 9 colon, 2 each of breast, salivary, sarcoma, and unknown primary, and 1 each of carcinoid, rectal neuroendocrine, small intestine, xanthogranuloma, ovarian, and pulmonary carcinosarcoma. The median age was 48 years (range 22-85). Twenty-nine pts received prior systemic therapy (median prior lines: 2, range 0-9). The ORR was 47% (N=15/32, 95% CI: 29-65). Objective responses were observed in 9 unique cancer types including colon, pancreatic, carcinoid, small intestine, salivary, xanthogranuloma, breast, ovarian, and sarcoma, and 5 additional patients had stable disease lasting ≥ 16 weeks. Median time to response was 1.9 months (range 0.7-7.3). Median DoR was not reached (median follow-up time of 13 months). Responses were ongoing in 73% (11/15) of pts. Safety among this population was consistent with the overall selpercatinib safety database. No patients in this cohort discontinued due to treatment-related AEs. Conclusion: Selpercatinib demonstrated promising antitumor activity in RET fusion-positive non-lung/non-thyroid cancers, including multiple treatment-refractory GI malignancies. Broad-based genomic profiling is essential to identify actionable oncogenic drivers, including RET fusions. The safety and efficacy of selpercatinib will continue to be explored in pts with these cancers in the ongoing LIBRETTO-001 study.

9084 Background: Brain metastases (BMs) are reported in 20–40% of pts with METex14 skipping NSCLC and present a high unmet need with poor prognosis. Tepotinib is a highly selective MET inhibitor that has demonstrated intracranial activity in preclinical MET-driven lung cancer orthotopic BM models, and has high binding in brain tissue with 25% of free tepotinib levels in brain, relative to plasma. In VISION Cohort A (N = 152), tepotinib had robust and durable clinical activity in pts with METex14 skipping NSCLC, with an objective response rate (ORR) of 45% and a median duration of response (mDOR) of 11.1 months. Here, we report the intracranial activity of tepotinib. Methods: In the Phase II VISION study, pts with METex14 skipping NSCLC received 500 mg QD (450 mg active moiety) oral tepotinib. Study eligibility allowed for pts with BM (neurologically stable on symptomatic therapy with stable steroids, and pts with asymptomatic BM). Primary endpoint: systemic OR per RECIST v1.1; subgroup analysis in pts with BM (determined by RECIST v1.1) was predefined. An ad hoc retrospective analysis of brain lesions determined by CT/MRI was conducted by an IRC using Response Assessment in Neuro-Oncology Brain Metastases (RANO-BM) criteria, which accounts for pts’ clinical status and steroid use. Responses were determined in pts with ≥1 evaluable post-baseline tumor assessment (due to the retrospective nature and resulting incomplete data, confirmation was not required). For pts with non-measurable lesions per RANO-BM (enhancing and non-enhancing non-target lesions [NTL]), disease control in the brain was defined as non-complete response/non-progressive disease. Data cut-off: July 1, 2020. Results: Based on RECIST v1.1, 23 pts in Cohort A had BM at baseline. Systemic efficacy in pts with BM (ORR 47.8% [95% CI: 26.8, 69.4], mDOR 9.5 months [95% CI: 5.5, not estimable]) was consistent with the overall population. 15 pts were evaluable by RANO-BM; 12 received prior radiotherapy for BM (median 6.4 weeks before tepotinib initiation [range 2.6–44]). Systemic best objective responses (BORs) were partial response (PR, n = 9), stable disease (SD, n = 3), and progressive disease (PD; n = 3). Of 7 pts with measurable CNS disease per RANO-BM (all of whom received prior radiotherapy), intracranial BORs were PR (n = 5; including 3 with complete disappearance of target lesions), SD (n = 1) and PD (n = 1). Of 8 pts with NTL only, 7 achieved intracranial disease control and 1 had PD. Of the 7 pts with disease control, 3 had CR of the enhancing NTL. Conclusions: Tepotinib demonstrated robust systemic activity in pts with METex14 skipping NSCLC with BM; this is complemented by intracranial activity in an ad hoc analysis using RANO-BM. Small pt numbers, a large proportion of pts with prior radiotherapy for BM, and the retrospective nature of analysis should be considered. Prospective evaluation of intracranial activity data from VISION Cohort C is ongoing. Clinical trial information: NCT02864992.

Immune checkpoint inhibitors such as pembrolizumab, ipilimumab, and nivolumab, now FDA-approved for use in treating several types of cancer, have been associated with immune-related adverse effects. Specifically, the antibodies targeting the programmed-cell death-1 immune checkpoint, pembrolizumab and nivolumab, have been rarely reported to induce the development of type 1 diabetes mellitus. Here we describe a case of a patient who developed antibody-positive type 1 diabetes mellitus following treatment with pembrolizumab in combination with systemic chemotherapy for metastatic adenocarcinoma of the lung. We will also provide a brief literature review of other rarely reported cases of type 1 diabetes presenting after treatment with pembrolizumab and nivolumab, as well as discussion regarding potential mechanisms of this adverse effect and its importance as these drugs continue to become even more widespread.

Supplemental Digital Content is available in the text., Background: Patient-level data from 2 phase III studies in patients with previously untreated, advanced-stage, nonsquamous non–small cell lung cancer (NSCLC) were pooled to examine outcomes with bevacizumab and chemotherapy based on age. Methods: Data from patients randomized to paclitaxel–carboplatin (PC)+bevacizumab in the Eastern Cooperative Oncology Group 4599 (E4599) and PointBreak studies were pooled and compared with E4599 patients randomized to PC alone. Patients were grouped by age: below 65, 65 to 74, 70 to 74, below 75, and 75 years or above. A multivariable model was used to calculate hazard ratios (HRs) and corresponding 95% confidence intervals (CIs) using time-to-event outcomes. Adverse events (AEs) were assessed by age group in each study. Results: The PC+bevacizumab and PC arms comprised 901 and 444 patients, respectively. PC+bevacizumab was associated with significant increases in overall survival relative to PC in patients below 65 years (hazards ratio [HR], 0.75; 95% confidence interval [CI], 0.62-0.89), 65 to 74 years (HR, 0.80; 95% CI, 0.64-1.00), 70 to 74 years (HR, 0.68; 95% CI, 0.48-0.96), and below 75 years (HR, 0.78; 95% CI, 0.68-0.89) but not in those aged 75 years or above (HR, 1.05; 95% CI, 0.70-1.57). Increased incidence of grade ≥3 AEs was reported with PC+bevacizumab versus PC in patients below 75 years (63% vs. 48%; P

Background Continuing to smoke after a cancer diagnosis can adversely influence the prognosis for patients with cancer. However, remarkably few studies have carefully examined the use of first-line FDA-approved medications for nicotine dependence in patients with cancer. This study evaluated the feasibility, safety, and effect on cessation of varenicline for smoking cessation in patients with cancer. Methods Data from 132 treatment-seeking smokers who received 12 weeks of open-label varenicline and five brief behavioral counseling sessions were used to evaluate the feasibility, safety, and impact on cessation of varenicline. The effects of abstinence on cognitive function and affect were also explored. Results Of 459 patients screened, 306 were eligible for the study (66.7%) and 132 entered treatment (43.1%). Retention was 84.1% over 12 weeks. The rate of biochemically verified abstinence at week 12 was 40.2%. Expected side effects were reported (e.g. sleep problems, nausea), but there were no reports of elevated depressed mood, suicidal thoughts, or cardiovascular events. Abstinence was associated with improved cognitive function and reduced negative affect over time (p

These NCCN Guidelines Insights focus on recent updates in the 2016 NCCN Guidelines for Non-Small Cell Lung Cancer (NSCLC; Versions 1-4). These NCCN Guidelines Insights will discuss new immunotherapeutic agents, such as nivolumab and pembrolizumab, for patients with metastatic NSCLC. For the 2016 update, the NCCN panel recommends immune checkpoint inhibitors as preferred agents (in the absence of contraindications) for second-line and beyond (subsequent) therapy in patients with metastatic NSCLC (both squamous and nonsquamous histologies). Nivolumab and pembrolizumab are preferred based on improved overall survival rates, higher response rates, longer duration of response, and fewer adverse events when compared with docetaxel therapy.

TPS9629 Background: Stage IV NSCLC patients who are never-smokers or with EGFR-mutated tumors generally do not benefit from single-agent immunotherapy. Retrospective subgroup analyses from recent phase III trials suggest that immunotherapy-chemotherapy +/- VEGF inhibition may overcome resistance to PD-L1 inhibitors in these patients, however prospective research on this is needed. This trial will examine a patient population with stage IV non-squamous disease who either have tumors that possess an EGFR exon 19 or 21 mutation or who are never-smoker wild-types, to determine whether the PD-L1 inhibitor atezolizumab in combination with pemetrexed, carboplatin, and bevacizumab can improve outcomes. Methods: This is a randomized, phase II, multi-center, open-label trial to assess pemetrexed/carboplatin and bevacizumab +/- atezolizumab in 117 subjects with stage IV non-squamous NSCLC. Randomization will be 2:1 favoring the + atezolizumab arm. Patients are stratified by EGFR mutation status (i.e. EGFR exon 19 or 21 vs. never-smoker wild-type). Never-smoker wild-type is defined as smoking < 100 cigarettes in a lifetime and without any EGFR mutation or ALK or ROS1 rearrangement. Patients with EGFR exon 19 or 21 mutated tumors must have progression of disease or intolerance of treatment with one or more prior TKIs. Primary endpoint is progression-free survival (PFS). Secondary endpoints include overall survival (OS), overall response rate, duration of response, and time to response. Primary objective is to compare PFS between arms. Secondary objectives include a safety analysis in all treated subjects, and comparisons of PFS and OS between arms for the patient subset with EGFR-mutated tumors. Correlative studies include interrogating flow cytometry-based peripheral blood biomarkers, examining the role of desmoplasia in local tumor immunosuppression, and assessing the contribution of estrogen metabolites to tumorigenesis. This study opened in August 2019 with 2 patients enrolled at the time of submission. Twenty U.S. sites through the NCCN are participating. This study was approved and funded by the National Comprehensive Cancer Network (NCCN) Oncology Research Program from general research support provided by Genentech, Inc.

9575 Background: In the phase II VISION study (NCT02864992) tepotinib had promising efficacy (response rate of 40–50% & median duration of response >1 y) and tolerable safety in pts with advanced NSCLC with METex14 skipping (3–4% of NSCLC), who are typically elderly with poor prognosis. Pt reported outcomes (PROs) of HRQoL are described here. Methods: Pts with advanced NSCLC positive for METex14 skipping by tissue or liquid biopsy received oral tepotinib 500 mg once daily; PROs were assessed using QLQ-LC13 (lung cancer symptoms), EORTC QLQ-C30 (Global health status [GHS] & 5 functional scales), and EQ-5D-5L (VAS). Questionnaires were completed at baseline (BL) and every 6 weeks (Wk); results were scored from 0–100 (minimal clinically important difference [MCID] ≥10 points). Mean change from BL was analyzed at Wk 12 (predefined analyses). Results: By 19 Jul 19 cut-off, 130 pts across treatment lines were enrolled (median age 74.2 y), with PROs available for 129. Questionnaire completion rates were 90.1% at Wk 12. Symptom burden at BL was moderate for advanced NSCLC; mean change from BL for PROs are shown in the table (better functioning: lower QLQ-LC13 or higher QLQ-C30 scores). For the QLQ-LC13 symptoms, mean changes from BL indicated a meaningful improvement in coughing, with a median time to improvement (2.8 months) paralleling the onset of objective response (within first 3 months), and a numerical improvement in dyspnea (–2.3 at Wk 12) and chest pain (–4.2 at Wk 12). QLQ-C30 values remained stable over treatment as did EQ-5D-5L scores (higher=better): mean (standard deviation, SD) change from BL score (60 [20.4]) was 6 (18.6) at Wk 6 and 5 (20.9) at Wk 12. Conclusions: In this first analysis of PROs in pts with advanced NSCLC with METex14 skipping with a moderate symptom burden, treatment with tepotinib led to a clinically meaningful improvement in coughing symptoms, while maintaining HRQoL. Coupled with the efficacy and safety profile, the predefined HRQoL analysis from the VISION study supports tepotinib as a promising treatment option for this elderly population with METex14+ NSCLC.

9616 Background: Stereotactic body radiotherapy (SBRT) provides high rates of treated metastasis control, stimulates innate and adaptive immune pathways, and is safe in patients treated with anti-PD1 monotherapy following SBRT. We hypothesize that SBRT may improve outcomes for patients receiving immunotherapy through both direct cytoreduction and increased immunogenicity. Within this context, we conducted a phase 1 trial designed to evaluate the safety of combination immune checkpoint blockade with nivolumab and ipilimumab(N/Ip) plus sequential (Seq) or concurrent (Con) multisite SBRT (mSBRT) in patients with stage IV NSCLC. Methods: Treatment naïve patients (EGFR/ALK WT) with advanced NSCLC received SBRT to 1 to 4 metastases. Not all metastases were targeted, and metastases > 65 mL were partially irradiated. Brain metastases were allowed on protocol, and those > 3mm were treated prior to enrollment. SBRT dose varied by anatomic site and ranged from 45 to 50 Gy in 3 to 5 fractions with predefined dose de-escalation if excess dose-limiting toxicities were observed. Patients on Seq arm received N/Ip between 1-7 days after completion of SBRT. Patients in Con arm received N/Ip prior to completion of SBRT. N/Ip continued until progression, development of toxicity, or up to 2 years. Patients underwent pre- and post-treatment biopsy of one irradiated lesion. Results: A total of 35 patients (Seq/Con 19/16) were enrolled and evaluable for toxicity analysis (SBRT and at least 1 cycle N/Ip). Brain metastases were present in 27%. PD-L1 expression: 0% (16), 1-49% (10), >50% (9). Median number of metastases treated with SBRT was 3.2. 6 patients experienced DLT (4 pneumonitis), resulting in dose reduction in central lung Seq cohort of the organs at risk (OAR) by 20%. Median PFS by RECIST (total/Seq/Con) was 5.9 mo, 95% CI: 4.9-13.1/ 6.2 mo, 95% CI: 3.5-12.6/ 5.9 mo, 95% CI: 3.1-18.0. RECIST best response was 11% CR, 57% PR, 6% SD, and 26% PD. Treatment past first progression was allowed, and time to second line therapy (chemotherapy) by arm (Seq/Con) was NR/17.5 months. Median OS has not been reached with median follow up of 15mo. PDL1 status did not impact PFS (p = 0.64) nor OS (p = 0.77). Conclusions: Multisite SBRT and concurrent N/Ip was well tolerated. Responses appear durable as median OS was not reached. Multimodality therapy with mSBRT and dual checkpoint inhibitor therapy resulted in impressive tumor control and clinical benefit with promising efficacy. Clinical trial information: NCT03223155 .

3610 Background: The highly selective TRK inhibitor larotrectinib is approved for the treatment of adult and pediatric cancers that harbor NTRK gene fusions; it achieves a 79% overall response rate (ORR) in this population (Hong et al., Lancet Oncol, 2020). The activity of larotrectinib in adults alone was further characterized in this update with a larger series of patients and more mature durability data. Methods: Adults (aged ≥18 y) with TRK fusion cancer treated in three larotrectinib clinical trials (NCT02122913, NCT02576431, and NCT02637687) were analyzed. Larotrectinib was administered 100 mg BID until disease progression, withdrawal, or unacceptable toxicity. ORR was investigator-assessed (RECIST v1.1). Compared to previously presented data on 74 patients, this expanded data set includes an additional 42 patients (data cutoff: July 15, 2019). Results: 116 adults (median age: 56 y, range 19–84 y; 53% female) with TRK fusion cancer were treated. Tumor types included thyroid cancer (22%), salivary gland cancer (19%), soft tissue sarcoma (16%), lung cancer (12%), colon cancer (7%), melanoma (5%), breast cancer (5%), GIST (3%), and 9 other types (≤2% each). NTRK fusions involved NTRK1 (43%), NTRK2 (3%), and NTRK3 (54%). 78% of patients had received prior systemic therapy (with 68% of those receiving ≥2 prior therapies). The ORR was 71% (95% CI 62–79): 10% complete response, 60% partial response (2% pending confirmation), 16% stable disease, 9% progressive disease, 3% not determined. In patients with brain metastases, the ORR was 71% (95% CI 42–92; 10 of 14 patients, all partial responses). Median duration of response for the overall data set (n = 116) was 35.2 mo (95% CI 21.6–not estimable [NE]). Median progression-free survival was 25.8 mo (95% CI 15.2–NE). Median overall survival was not reached (range 0.5+ to 51.6+ mo) at a median follow-up of 15.8 mo. Duration of treatment ranged from 0.10 to 51.6+ mo. 12% of patients had dose reductions. One patient (1%) discontinued due to a larotrectinib-related adverse event (AE). AEs were mostly grade 1–2; no new unexpected AEs were reported. Conclusions: In an expanded data set of adults with TRK fusion cancer, larotrectinib demonstrated robust and durable tumor-agnostic efficacy and favorable safety, supporting NTRK gene fusion testing in patients with solid tumors of any type.

Continuing to smoke after a cancer diagnosis undermines prognosis. Yet few trials have tested Food and Drug Administration (FDA)-approved tobacco use medications in this population. Extended use varenicline may represent an effective treatment for cancer patients who smoke given barriers to cessation including a prolonged time line for relapse.A placebo-controlled randomized trial tested 12 weeks of varenicline plus 12 weeks of placebo (standard [ST]) vs 24 weeks of varenicline (extended [ET]) with seven counseling sessions for treatment-seeking cancer patients who smoke (N = 207). Primary outcomes were 7-day biochemically confirmed abstinence at weeks 24 and 52. Treatment adherence and side effects, adverse and serious adverse events, and blood pressure were assessed.Point prevalence and continuous abstinence quit rates at weeks 24 and 52 were not significantly different across treatment arms (P's 0.05). Adherence (43% of sample) significantly interacted with treatment arm for week 24 point prevalence (odds ratio [OR] = 2.31; 95% confidence interval [CI], 1.15-4.63; P = 0.02) and continuous (OR = 5.82; 95% CI, 2.66-12.71; P 0.001) abstinence. For both outcomes, adherent participants who received ET reported higher abstinence (60.5% and 44.2%) vs ST (44.7% and 27.7%), but differences in quit rates between arms were not significant for nonadherent participants (ET: 9.7% and 4.8%; ST: 12.7% and 10.9%). There were no significant differences between treatment arms on side effects, adverse and serious adverse events, and rates of high blood pressure (P's 0.05).Compared with ST, ET varenicline does not increase patient risk and increases smoking cessation rates among patients who adhere to treatment. Studies are needed to identify effective methods to increase medication adherence to treat patient tobacco use effectively.
