Purpose We assessed the safety and antitumor activity of avelumab, a fully human anti–programmed death-ligand 1 (PD-L1) IgG1 antibody, in patients with refractory metastatic urothelial carcinoma. Methods In this phase Ib, multicenter, expansion cohort, patients with urothelial carcinoma progressing after platinum-based chemotherapy and unselected for PD-L1 expression received avelumab 10 mg/kg intravenously every 2 weeks. The primary objectives were safety and tolerability. Secondary objectives included confirmed objective response rate (Response Evaluation Criteria in Solid Tumors [RECIST] version 1.1), progression-free survival, overall survival (OS), and PD-L1–associated clinical activity. PD-L1 positivity was defined as expression by immunohistochemistry on ≥ 5% of tumor cells. Results Forty-four patients were treated with avelumab and followed for a median of 16.5 months (interquartile range, 15.8 to 16.7 months). The data cutoff was March 19, 2016. The most frequent treatment-related adverse events of any grade were fatigue/asthenia (31.8%), infusion-related reaction (20.5%), and nausea (11.4%). Grades 3 to 4 treatment-related adverse events occurred in three patients (6.8%) and included asthenia, AST elevation, creatine phosphokinase elevation, and decreased appetite. The confirmed objective response rate by independent central review was 18.2% (95% CI, 8.2% to 32.7%; five complete responses and three partial responses). The median duration of response was not reached (95% CI, 12.1 weeks to not estimable), and responses were ongoing in six patients (75.0%), including four of five complete responses. Seven of eight responding patients had PD-L1–positive tumors. The median progression-free survival was 11.6 weeks (95% CI, 6.1 to 17.4 weeks); the median OS was 13.7 months (95% CI, 8.5 months to not estimable), with a 12-month OS rate of 54.3% (95% CI, 37.9% to 68.1%). Conclusion Avelumab was well tolerated and associated with durable responses and prolonged survival in patients with refractory metastatic UC.

PURPOSE Nivolumab, an anti–programmed death-1 monoclonal antibody, has demonstrated frequent and durable responses in relapsed/refractory classic Hodgkin lymphoma (cHL). We report results from Cohort D of the CheckMate 205 trial, which assessed nivolumab monotherapy followed by nivolumab plus doxorubicin, vinblastine, and dacarbazine (N-AVD) for newly diagnosed cHL. METHODS Patients 18 years of age or older with untreated, advanced-stage (defined as III to IV and IIB with unfavorable risk factors) cHL were eligible for Cohort D of this multicenter, noncomparative, phase II trial. Patients received nivolumab monotherapy for four doses, followed by 12 doses of N-AVD; all doses were every 2 weeks, and nivolumab was administered at 240 mg intravenously. The primary end point was safety. Efficacy end points included objective response rate and modified progression-free survival, defined as time to disease progression/relapse, death, or next therapy. Chromosome 9p24.1 alterations and programmed death-ligand 1 expression were assessed in Hodgkin Reed-Sternberg cells in evaluable patients. RESULTS A total of 51 patients were enrolled and treated. At diagnosis, 49% of patients had an International Prognostic Score of 3 or greater. Overall, 59% experienced a grade 3 to 4 treatment-related adverse event. Treatment-related febrile neutropenia was reported in 10% of patients. Endocrine immune-mediated adverse events were all grade 1 to 2 and did not require high-dose corticosteroids; all nonendocrine immune-mediated adverse events resolved (most commonly, rash; 5.9%). At the end of therapy, the objective response rate (95% CI) per independent radiology review committee was 84% (71% to 93%), with 67% (52% to 79%), achieving complete remission (five patients [10%] were nonevaluable and counted as nonresponders). With a minimum follow-up of 9.4 months, 9-month modified progression-free survival was 92%. Patients with higher-level Hodgkin Reed-Sternberg programmed death-ligand 1 expression had more favorable responses to N-AVD ( P = .041). CONCLUSION Nivolumab followed by N-AVD was associated with promising efficacy and safety profiles for newly diagnosed, advanced-stage cHL.

265^ Background: Rh-endostatin is a new recombinant human endostatin that can inhibit tumor endothelial cell proliferation, angiogenesis, and tumor growth in the pre-clinical studies. A phase III study revealed that rh-endostatin in combination with chemotherapy shows a synergic activity in advanced NSCLC patients. This study aims to evaluate the response, median progression-free survival (PFS), overall survival time (OS), and safety of the regimen, paclitaxel/gemcitabine/cisplatin (TGP) plus rh-endostatin, in patients with advanced urothelial transitional carcinoma. Methods: The phase II trial included 35 patients with histologically diagnozed advanced or metastatic urothelial carcinoma, ECOG performance status 0-1, and GFR>60ml/min. TGP chemotherapy plus rh-endostatin as a first line treatment included: paclitaxel (80 mg/m2, d1&8), gemcitabine (1000 mg/m2, d1&8), cisplatin (30 mg/m2, d1 to 3) and rh-endostatin (15mg, d1 to 14, every 21d). For every 2 cycles, patients were evaluated for progression or response. Patients who had achieved an objective response (complete or partial) or who had stable disease were further treated for two cycles. Results: The overall objective response rate was 62.8% (95% confidence interval [CI, 46.8% to 78.8%]), including 4 (11.4%) complete response (CR) and 18 (51.4%) partial responses (PRs). Six patients (17.1%) had stable disease (SD), and 7 (20.0%) had progression disease (PD). The disease control rate was 80.0%. The median progression-free survival and overall survival have not been reached. The most common adverse events included gastrointestinal reaction, alopecia, and myelosuppression. Grade 3/4 adverse events, including thrombocytopenia in 42.9% (15/35) of patients and leucopenia in 34.3% (12/35) of patients, were observed. Conclusions: The addition of rh-endostatin to TGP regimen for advanced urothelial carcinoma patients might have higher response rate. Rh-Endostatinin combination with TGP chemotherapy showed a synergic activityand a favorable toxic profile in advanced urothelial carcinoma patients. No significant financial relationships to disclose.

PURPOSE Locally advanced or metastatic urothelial carcinoma is an incurable disease with limited treatment options, especially for patients who were previously treated with platinum and anti–programmed death 1 or anti–programmed death ligand 1 (PD-1/L1) therapy. Enfortumab vedotin is an antibody–drug conjugate that targets Nectin-4, which is highly expressed in urothelial carcinoma. METHODS EV-201 is a global, phase II, single-arm study of enfortumab vedotin 1.25 mg/kg (intravenously on days 1, 8, and 15 of every 28-day cycle) in patients with locally advanced or metastatic urothelial carcinoma who were previously treated with platinum chemotherapy and anti–PD-1/L1 therapy. The primary end point was objective response rate per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 by blinded independent central review. Key secondary end points were duration of response, progression-free survival, overall survival, safety, and tolerability. RESULTS Enfortumab vedotin was administered to 125 patients with metastatic urothelial carcinoma. Median follow-up was 10.2 months (range, 0.5 to 16.5 months). Confirmed objective response rate was 44% (95% CI, 35.1% to 53.2%), including 12% complete responses. Similar responses were observed in prespecified subgroups, such as those patients with liver metastases and those with no response to prior anti–PD-1/L1 therapy. Median duration of response was 7.6 months (range, 0.95 to 11.30+ months). The most common treatment-related adverse events were fatigue (50%), any peripheral neuropathy (50%), alopecia (49%), any rash (48%), decreased appetite (44%), and dysgeusia (40%). No single treatment-related adverse events grade 3 or greater occurred in 10% or more of patients. CONCLUSION Enfortumab vedotin demonstrated a clinically meaningful response rate with a manageable and tolerable safety profile in patients with locally advanced or metastatic urothelial carcinoma who were previously treated with platinum and anti–PD-1/L1 therapies.

PURPOSE A prospective randomized trial was performed to determine if the addition of methotrexate, vinblastine, and doxorubicin to cisplatin (M-VAC) imparted a response rate or a survival advantage over single-agent cisplatin in patients with advanced urothelial carcinoma. PATIENTS AND METHODS From October 1984 through May 1989, 269 patients with advanced urothelial carcinoma were entered onto this international intergroup trial and randomized to receive intravenous (IV) cisplatin (70 mg/m2) alone or with methotrexate (30 mg/m2 on days 1, 15, 22), vinblastine (3 mg/m2 on days 2, 15, 22) plus doxorubicin (30 mg/m2 on day 2). Cycles were repeated every 28 days until tumor progression or a maximum of six cycles. There were 246 fully assessable patients of whom 126 were randomized to cisplatin alone and 120 were randomized to the M-VAC regimen. RESULTS As expected, the M-VAC regimen was associated with a greater toxicity, especially leukopenia, mucositis, granulocytopenic fever, and drug-related mortality. Response rates were superior for the M-VAC regimen compared with single-agent cisplatin (39% v 12%; P less than .0001). Similarly, the progression-free survival (10.0 v 4.3 months) and overall survival (12.5 v 8.2 months) were significantly greater for the combined therapy arm. CONCLUSION Although a more toxic regimen, we found M-VAC to be superior to single-agent cisplatin with respect to response rate, duration of remission, and overall survival in patients with advanced urothelial carcinoma.

Purpose To the best of our knowledge, this study is the first to compare dual inhibition of PI3K/mammalian target of rapamycin (mTOR) by apitolisib (GDC-0980) against single inhibition of mTORC1 by everolimus in metastatic renal cell carcinoma (mRCC). Patients and Methods Patients with clear-cell mRCC who progressed on or after vascular endothelial growth factor–targeted therapy were randomly assigned to apitolisib 40 mg once per day or to everolimus 10 mg once per day. End points included progression-free survival, safety, overall survival, and objective response rate. Biomarker assessments were conducted. Results Eighty-five patients were randomly assigned. After 67 events, stratified analysis revealed that median progression-free survival was significantly shorter for apitolisib than for everolimus (3.7 v 6.1 months; hazard ratio, 2.12 [95% CI, 1.23 to 3.63; P < .01]); apitolisib was not favored in any stratification subgroup. Median overall survival was not significantly different but trended in favor of everolimus (16.5 v 22.8 months; hazard ratio, 1.77 [95% CI, 0.97 to 3.24; P = .06]). The objective response rate was 7.1% for apitolisib and 11.6% for everolimus. Patients administered apitolisib with a greater incidence of grade 3 to 4 adverse events were more likely to discontinue treatment (31% v 12% for everolimus). No drug-related deaths were observed. Apitolisib in comparison with everolimus was associated with substantially more high-grade hyperglycemia (40% v 9%) and rash (24% v 2%). Apitolisib pharmacokinetics suggested a relationship between exposure, and rash and hyperglycemia. Retrospective biomarker analyses revealed a relationship between VHL mutation status and outcome with everolimus but not with apitolisib. High hypoxia-inducible factor 1α protein expression was associated with better outcome in both arms. Conclusion This study demonstrated that dual PI3K/mTOR inhibition by apitolisib was less effective than was everolimus in mRCC, likely because full blockade of PI3K/mTOR signaling resulted in multiple on-target adverse events. VHL mutation and hypoxia-inducible factor 1α expression may be predictive of an mTOR inhibitor benefit, although prospective validation is required.

PURPOSE Treatment options are limited for patients with recurrent and/or metastatic (R/M) cutaneous squamous cell carcinoma (cSCC); mortality rates exceed 70% in patients with distant metastases. Here, we present the first interim analysis of the R/M cSCC cohort from the 2-cohort—locally advanced and R/M—phase II KEYNOTE-629 study. PATIENTS AND METHODS Patients with R/M cSCC not amenable to surgery or radiation received pembrolizumab 200 mg every 3 weeks. The primary end point was objective response rate per RECIST v1.1. Secondary end points were duration of response, disease control rate, progression-free survival, overall survival, and safety. RESULTS At data cutoff (April 8, 2019), median follow-up of 105 enrolled patients in the R/M cohort was 11.4 months (range, 0.4 to 16.3 months). Objective response rate was 34.3% (95% CI, 25.3% to 44.2%; 4 complete responses, 32 partial responses), and disease control rate was 52.4% (95% CI, 42.4% to 62.2%). Median duration of response was not reached (range, 2.7 to 13.1+ months; ‘+’ refers to ongoing response at data cutoff). Median progression-free survival was 6.9 months (95% CI, 3.1 months to 8.5 months). Median overall survival was not reached (95% CI, 10.7 months to not reached). Treatment-related adverse events occurred in 66.7% of patients (n = 70), the most common of which were pruritus (n = 15; 14.3%), asthenia (n = 14; 13.3%), and fatigue (n = 13; 12.4%). Grade 3 to 5 treatment-related adverse events occurred in 5.7% (n = 6) of patients. One patient died of treatment-related cranial nerve neuropathy. CONCLUSION Pembrolizumab demonstrated effective antitumor activity; clinically meaningful, durable responses; and acceptable safety in primarily elderly patients with R/M cSCC, supporting its use in clinical practice. Pembrolizumab adverse events in this study were consistent with its established safety profile.

Metastatic Urothelial Carcinoma

393 Background: Patients with locally advanced or metastatic urothelial carcinoma (la/mUC) have poor survival following progression after platinum-containing chemotherapy and PD-1/L1 inhibitor regimens. Enfortumab vedotin (EV) is an antibody-drug conjugate directed to Nectin-4, a cell adhesion molecule highly expressed in urothelial carcinoma, with remarkable efficacy observed in a single-arm trial in this setting. This randomized phase III study (EV-301) was performed to confirm these findings. Methods: EV-301 (NCT03474107) is a global, open-label phase III study of EV vs chemotherapy conducted in patients with la/mUC who had received a prior platinum-containing chemotherapy and had disease progression during or after PD-1/L1 inhibitor treatment. Patients were randomized 1:1 to receive EV (1.25 mg/kg) on Days 1, 8, and 15 of each 28-day cycle or investigator choice of standard docetaxel, paclitaxel, or vinflunine chemotherapy. The primary endpoint was overall survival (OS); secondary endpoints included investigator-assessed progression-free survival (PFS), objective response rate (ORR), and disease control rate (DCR) per RECIST v1.1, as well as safety/tolerability. A prespecified interim analysis, which tested OS at an adjusted 1-sided significance level of P = 0.00679, was performed when ≥285 deaths had occurred. The results of this interim analysis are presented here. Results: Overall, 608 patients with la/mUC were randomly assigned to EV (n=301) or chemotherapy (n=307). As of July 15, 2020, 301 deaths had occurred (EV, n=134; chemotherapy, n=167). After an 11.1 mo follow-up, median OS was significantly prolonged by 3.9 mo with EV compared with chemotherapy (median OS: 12.9 vs 9.0 mo, respectively; HR=0.70 [95% CI: 0.56-0.89], 1-sided P =0.001). Additionally, the OS benefit of EV was retained in the majority of prespecified subgroups. Progression-free survival also was improved with EV (5.6 mo) vs chemotherapy (3.7 mo) (HR=0.61 [95% CI: 0.50-0.75]; 1-sided P <0.00001). Both ORR and DCR were significantly higher with EV vs chemotherapy (40.6% vs 17.9% and 71.9% vs 53.4%, respectively; 1-sided P <0.001 each). Rates of treatment-related adverse events (TRAEs; 93.9% vs 91.8%), including serious TRAEs (22.6% vs 23.4%), were comparable between the EV and chemotherapy groups. Rates of grade ≥3 TRAEs were ~50% in both groups; decreased neutrophil count (13.4%) and white blood cell count (6.9%) were more common in the chemotherapy group, and maculo-papular rash (7.4%) was more common in the EV group. Conclusions: EV is the first therapy to show significant survival advantage over standard chemotherapy in patients with treatment-experienced la/mUC. With robust clinical benefit and a tolerable safety profile, EV is a new standard of care for this aggressive disease. Clinical trial information: NCT03474107.

PURPOSE Adrenocortical carcinomas (ACC) are rare and aggressive malignancies with limited treatment options. This study was undertaken to evaluate the immunogenicity of ACC. PATIENTS AND METHODS Patients with advanced ACC were enrolled in a phase II study to evaluate the clinical activity of pembrolizumab 200 mg every 3 weeks, without restriction on prior therapy. The primary end point was objective response rate. Efficacy was correlated with tumor programmed death-ligand 1 expression, microsatellite-high and/or mismatch repair deficient (MSI-H/MMR-D) status, and somatic and germline genomic correlates. RESULTS We enrolled 39 patients with advanced ACC and herein report after a median follow-up of 17.8 months (range, 5.4 months to 34.7 months). The objective response rate to pembrolizumab was 23% (nine patients; 95% CI, 11% to 39%), and the disease control rate was 52% (16 patients; 95% CI, 33% to 69%). The median duration of response was not reached (lower 95% CI, 4.1 months). Two of six patients with MSI-H/MMR-D tumors responded. The other seven patients with objective responses had microsatellite stable tumors. The median progression-free survival was 2.1 months (95% CI, 2.0 months to 10.7 months), and the median overall survival was 24.9 months (95% CI, 4.2 months to not reached). Thirteen percent of patients (n = 5) had treatment-related grade 3 or 4 adverse events. Tumor programmed death-ligand 1 expression and MSI-H/MMR-D status were not associated with objective response. CONCLUSION MSI-H/MMR-D tumors, for which pembrolizumab is a standard therapy, are more common in ACC than has been recognized. In advanced ACC that is microsatellite stable, pembrolizumab provided clinically meaningful and durable antitumor activity with a manageable safety profile.

Purpose. To assess the incidence and severity of adverse events; to explore clinical factors associated with grade 3–4 non-hematologic toxicity; to assess the immediate efficacy and progression-free survival during treatment with the FOLFIRI regimen in combination with aflibercept in Russia.Materials and Methods. A retrospective multicenter study has been conducted with data collected from 20 clinics in 15 regions of Russia. There was no statistical hypothesis. Progression-free survival was the main efficacy criterion. The statistical analysis was performed using IBM SPPS Statistics v. 20 software.Results. FOLFIRI and Aflibercept combination was administered to 264 patients. The mean number of treatment cycles was 6 (1 to 29). The toxicity of aflibercept was addressed by dose reduction and dosing delay in 10.1 % and 11.4 % of patients, respectively, and dose reductions and dosing delays in any of FOLIFRI components were reported in 20.1 % of participants. The objective response rate was 20.3 %. The median progression-free survival in patients receiving second-line treatment was 6 months (95 % CI: 5.3–6.6 months). Seventy-two percent of patients experienced any grade of adverse events most of which were limited to grade 1–2 (62.1 %). Non-hematologic toxicity was reported in 64 % of patients (grade 3–4 in 17.9 %). Hematologic events were detected in only 17.9 % of patients. Multifactorial analysis has shown that drug therapy for concomitant diseases (OR 1.98, 95 % CI: 1.04–3.78, p = 0.037) and the number of chemotherapy lines prior to aflibercept (ОR 1.5, 95 % CI: 1.06–2.11, p = 0.02) were independent predictors of grade 3–4 non-hematologic toxicity.Conclusions. Objective response rate, progression-free survival, and frequency of toxicity-related aflibercept discontinuations in the Russian study with patients receiving aflibercept in combination with FOLFIRI regimen as a second-line treatment has shown the results that were comparable with VELOUR study. Comorbidities requiring drug treatment and the number of prior chemotherapy lines appear to be risk factors for grade 3–4 nonhematological toxicity events.
