RESUMEN
BACKGROUND AND OBJECTIVE: Abiraterone acetate (abiraterone) plus prednisone is approved for the treatment of metastatic castration-resistant prostate cancer (mCRPC). Our aim was to evaluate the efficacy and safety of pembrolizumab plus abiraterone in mCRPC. METHODS: In cohort D of the phase 1b/2 KEYNOTE-365 study (NCT02861573), patients were chemotherapy-naïve, had disease progression ≤6 mo before screening, and had either not received prior next-generation hormonal agents for mCRPC or had received prior enzalutamide for mCRPC and had disease progression or became intolerant to enzalutamide. Patients received pembrolizumab 200 mg intravenously every 3 wk plus abiraterone 1000 mg orally once daily and prednisone 5 mg orally twice daily. The primary endpoints were safety, prostate-specific antigen (PSA) response rate, and objective response rate (ORR) according to Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) by blinded independent central review (BICR). Secondary endpoints included radiographic progression-free survival (rPFS) according to Prostate Cancer Clinical Trials Working Group 3-modified RECIST v1.1 by BICR and overall survival (OS). KEY FINDINGS AND LIMITATIONS: For the 103 patients who were treated, median follow-up was 28 mo (interquartile range 26-31). The confirmed PSA response rate was 56% (58/103 patients). The ORR for patients with RECIST v1.1-measurable disease was 16% (6/37 patients). Median rPFS was 15 mo (95% confidence interval 9.2-22) and median OS was 30 mo (95% confidence interval 23-not reached); the estimated 24-mo OS rate was 58%. In total, 91% of patients experienced treatment-related adverse events, and 39% experienced grade 3-5 events. Grade 3/4 elevation of alanine aminotransferase (ALT) or aspartate aminotransferase (AST) was observed in 12% and 6.8% of patients, respectively. One patient died due to treatment-related myasthenic syndrome. Study limitations include the single-arm design. CONCLUSIONS: Pembrolizumab plus abiraterone and prednisone demonstrated antitumor activity and acceptable safety in patients with chemotherapy-naïve mCRPC. Higher incidence of grade 3/4 elevated ALT/AST occurred than was reported for the individual agents. PATIENT SUMMARY: For patients with metastatic castratation-resistant prostate cancer, the drug combination of pembrolizumab plus abiraterone and prednisone showed antitumor activity and acceptable safety.
RESUMEN
INTRODUCTION: Papillary renal cell carcinoma (pRCC) is a rare and aggressive cancer with no specifically established therapeutic strategy in the metastatic setting. Combinations of tyrosine kinase and immune checkpoint inhibitors (ICI) are a promising option. We aimed to study the immune landscape of metastatic pRCC, and its interactions with angiogenesis pathways, to search for potential therapeutic targets. METHODS: The expression of immune markers (PD-L1, PD-1, PD-L2, LAG-3) and angiogenic pathways (CAIX, c-MET), was analyzed by immunohistochemistry on 68 metastatic pRCC retrieved from a retrospective multicenter GETUG cohort. Our primary endpoint was to estimate the prevalence of PD-L1 expression and its prognostic impact in metastatic pRCC. Secondary endpoints included the evaluation of other immune markers (PD-1, PD-L2, and LAG-3) and their association with PD-L1. We also assessed angiogenic markers and their association with PD-L1. RESULTS: Overall, 27.9 % of tumors were PD-L1 positive. PD-L2 was more frequently expressed (45.6 %), PD-1 and LAG-3 were positive in 17.6 % and 19.1 % respectively. None of these markers was correlated with PD-L1 expression. 66 % (45/68) expressed at least one immune marker, and 43 % (29/68) were "double-positive", as they expressed both immune and angiogenic markers. OS was significantly shorter for patients with PD-L1 positive pRCC. A multivariate analysis confirmed a significant association between PD-L1 expression and shorter overall survival (HR = 4.0, p = 0.01). CONCLUSION: These results reinforce clinical data on the expected benefit of ICI in metastatic pRCC treatment, as PD-L1 expression is a factor of poor prognosis in this multicenter cohort.

BACKGROUND: The Lung Immune Prognostic Index (LIPI) is associated with immune checkpoint inhibitors (ICI) outcomes across different solid tumors, particularly in non-small cell lung cancer. Data regarding the prognostic and/or predictive role of LIPI in metastatic renal cell carcinoma (mRCC) are still scarce. The aim of this study was to evaluate whether LIPI could be predictive of survival in mRCC patients. METHODS: We used patient level data from three different prospective studies (NIVOREN trial: nivolumab; TORAVA trial: VEGF/VEGFR-targeted therapy (TT); CheckMate 214: nivolumab-ipilimumab vs sunitinib). LIPI was calculated based on a derived neutrophils/(leukocyte-neutrophil) ratio > 3 and lactate-dehydrogenase >upper limit of normal, classifying patients into three groups (LIPI good, 0 factors;LIPI intermediate (int), 1 factor;LIPI poor, 2 factors) and/or into two groups (LIPI good, 0 factors;LIPI int/poor, 1-2 factors) according to trial sample size. Primary and secondary endpoints were overall survival (OS) and progression-free survival (PFS). RESULTS: In the Nivolumab dataset (n = 619), LIPI was significantly associated with OS (LIPI-good 30.1 vs 13.8 months in the LIPI int/poor; HR= 0.47) and PFS (HR=0.74). In the VEGF/VEGFR-TT dataset (n = 159), only a correlation with PFS was observed. In the CheckMate214 dataset (n = 1084), LIPI was significantly associated with OS (nivolumab-ipilimumab OS LIPI good vs int/poor: HR=0.55, p < 0.0001; sunitinib: OS LIPI good vs int/poor: 0.38, p < 0.0001) in both treatment groups in univariate and multivariate analysis. CONCLUSIONS: Pretreatment-LIPI correlated with worse survival outcomes in mRCC treated with either ICI or antiangiogenic therapy, confirming LIPI's prognostic role in mRCC irrespective of systemic treatment used.

INTRODUCTION: Immune checkpoint inhibitors are standard of care in metastatic renal cell carcinoma but their activity and safety in elderly patients is insufficiently explored. We evaluated outcomes of elderly patients with mRCC treated with nivolumab in the GETUG-AFU 26 NIVOREN phase 2 trial (NCT03013335) and conducted exploratory circulating biomarker analyses. METHODS: Patients with mRCC were treated with nivolumab after at least one antiangiogenic therapy. The main endpoint of this analysis was safety in patients ≥ 70 years old (y.o), as per the rate of treatment-related grade 3-5 events (TRAE). Secondary endpoints included overall response rate (ORR), progression-free survival (PFS), overall survival. Exploration of candidate biomarkers associated with aging included baseline circulating cytokines involved in inflammation, adhesion, immune checkpoints, angiogenesis (IL6, IL7, IL8, BAFF, CXCL13, VCAM-1, 4-1BB, VEGF). RESULTS: Of 720 patients, 515 were < 70 y.o and 205 ≥ 70 y.o. Patients ≥ 70 y.o exhibited numerically less IMDC poor risk disease (21.0% vs 26.9%), sarcomatoid component (4.9% vs 9.8%) or brain metastases (5.9% vs. 14.7%), but more previous treatment lines (≥ 2 in 54.1% vs 48.5%). TRAE were higher in patients ≥ 70 y.o (24.9% vs. 17.9%, p = 0.033). Respective ORR (19.2% vs. 22.1%) and median PFS (4.5 versus 3.0 months, HR 0.97 [95%CI 0.81-1.15]) were similar. Overall survival was shorter in patients ≥ 70 y.o (19.3 versus 26.9 months, HR 1.26 [95%CI 1.04-1.51]), but not significantly in a competitive risk model. Only V-CAM1 and 4-1BB were found to be increased in patients ≥ 70 y.o. CONCLUSIONS: Nivolumab displayed higher grade 3/4 TRAE but manageable toxicity in elderly patients, with sustained activity. Elderly patients did not display specific inflammatory or angiogenic circulating profiles.

BACKGROUND: The optimal perioperative chemotherapy for patients with muscle-invasive bladder cancer is not defined. The VESPER (French Genito-Urinary Tumor Group and French Association of Urology V05) trial reported improved 3-year progression-free survival with dose-dense methotrexate, vinblastine, doxorubicin and cisplatin (dd-MVAC) versus gemcitabine and cisplatin (GC) in patients who received neoadjuvant therapy, but not in the overall perioperative setting. In this Article, we report on the secondary endpoints of overall survival and time to death due to bladder cancer at 5-year follow-up. METHODS: VESPER was an open-label, randomised, phase 3 trial done at 28 university hospitals or comprehensive cancer centres in France, in which adults (age ≤18 years and ≤80 years) with primary bladder cancer and histologically confirmed muscle-invasive urothelial carcinoma were randomly allocated (1:1; block size four) to treatment with dd-MVAC (every 2 weeks for a total of six cycles) or GC (every 3 weeks for a total of four cycles). Overall survival and time to death due to bladder cancer (presented as 5-year cumulative incidence of death due to bladder cancer) was analysed by intention to treat (ITT) in all randomly assigned patients. Overall survival was assessed by the Kaplan-Meier method with the treatment groups compared with log-rank test stratified for mode of administration of chemotherapy (neoadjuvant or adjuvant) and lymph node involvement. Time to death due to bladder cancer was analysed with an Aalen model for competing risks and a Fine and Gray regression model stratified for the same two covariates. Results were presented for the total perioperative population and for the neoadjuvant and adjuvant subgroups. The trial is registered with ClinicalTrials.gov, NCT01812369, and is complete. FINDINGS: From Feb 25, 2013, to March 1, 2018, 500 patients were randomly assigned, of whom 493 were included in the final ITT population (245 [50%] in the GC group and 248 [50%] in the dd-MVAC group; 408 [83%] male and 85 [17%] female). 437 (89%) patients received neoadjuvant chemotherapy. Median follow-up was 5·3 years (IQR 5·1-5·4); 190 deaths at the 5-year cutoff were reported. In the perioperative setting (total ITT population), we found no evidence of association of overall survival at 5 years with dd-MVAC treatment versus GC treatment (64% [95% CI 58-70] vs 56% [50-63], stratified hazard ratio [HRstrat] 0·79 [95% CI 0·59-1·05]). Time to death due to bladder cancer was increased in the dd-MVAC group compared with in the GC group (5-year cumulative incidence of death: 27% [95% CI 21-32] vs 40% [34-46], HRstrat 0·61 [95% CI 0·45-0·84]). In the neoadjuvant subgroup, overall survival at 5 years was improved in the dd-MVAC group versus the GC group (66% [95% CI 60-73] vs 57% [50-64], HR 0·71 [95% CI 0·52-0·97]), as was time to death due to bladder cancer (5-year cumulative incidence: 24% [18-30] vs 38% [32-45], HR 0·55 [0·39-0·78]). In the adjuvant subgroup, the results were not conclusive due to the small sample size. Bladder cancer progression was the cause of death for 157 (83%) of the 190 deaths; other causes of death included cardiovascular events (eight [4%] deaths), deaths related to chemotherapy toxicity (four [2%]), and secondary cancers (four [2%]). INTERPRETATION: Our results on overall survival at 5 years were in accordance with the primary endpoint analysis (3-year progression-free survival). We found no evidence of improved overall survival with dd-MVAC over GC in the perioperative setting, but the data support the use of six cycles of dd-MVAC over four cycles of GC in the neoadjuvant setting. These results should impact practice and future trials of immunotherapy in bladder cancer. FUNDING: French National Cancer Institute.

BACKGROUND: Limited responses have been observed in patients treated with enzalutamide after disease progression on abiraterone for metastatic castration-resistant prostate cancer (mCRPC), but androgen receptor signaling impacts T-cell function. OBJECTIVE: To evaluate the efficacy and safety of pembrolizumab plus enzalutamide in mCRPC. DESIGN, SETTING, AND PARTICIPANTS: Patients in cohort C of the phase 1b/2 KEYNOTE-365 study, who received ≥4 wk of treatment with abiraterone acetate in the prechemotherapy mCRPC state and experienced treatment failure or became drug-intolerant, were included. INTERVENTION: Pembrolizumab 200 mg intravenously every 3 wk plus enzalutamide 160 mg orally once daily. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoints were safety, the confirmed prostate-specific antigen (PSA) response rate, and the objective response rate (ORR) according to Response Evaluation Criteria in Solid Tumors version 1.1 on blinded independent central review (BICR). Secondary endpoints included radiographic progression-free survival (rPFS) on BICR and overall survival (OS). RESULTS AND LIMITATIONS: A total of 102 patients received pembrolizumab plus enzalutamide. Median follow-up was 51 mo (interquartile range 37-56). The confirmed PSA response rate was 24% (95% confidence interval [CI] 16-33%). The confirmed ORR was 11% (95% CI 2.9-25%; 4/38 patients; two complete responses). Median rPFS was 6.0 mo (95% CI 4.1-6.3). Median OS was 20 mo (95% CI 17-24). Treatment-related adverse events (TRAEs) occurred in 94 patients (92%); grade 3-5 TRAEs occurred in 44 patients (43%). The incidence of treatment-related rash was higher with combination therapy than expected from the safety profile of each drug. One patient (1.0%) died of a TRAE (cause unknown). Study limitations include the single-arm design. CONCLUSIONS: Pembrolizumab plus enzalutamide had limited antitumor activity in patients who received prior abiraterone treatment without previous chemotherapy for mCRPC, with a safety profile consistent with the individual profiles of each agent. PATIENT SUMMARY: Pembrolizumab plus enzalutamide showed limited antitumor activity and manageable safety in patients with metastatic castration-resistant prostate cancer. The KEYNOTE-365 trial is registered on ClinicalTrials.gov as NCT02861573.
RESUMEN
BACKGROUND: Glandular metastases (GMs; adrenal gland, pancreas, thyroid, ovary, breast, or prostate) are rare in metastatic clear cell renal cell carcinoma (mccRCC). Previous studies have indicated that GM patients treated with antiangiogenic therapy experience significantly longer overall survival (OS). OBJECTIVES: To assess outcomes for mccRCC with or without GMs treated with nivolumab. DESIGN, SETTING, AND PARTICIPANTS: The GETUG-AFU-26 NIVOREN phase 2 trial evaluated the activity and safety of nivolumab in patients with mccRCC who experienced failure of antiangiogenic therapies (NCT03013335). In this ancillary study, patients were divided into two groups according to the presence or absence of at least one GM. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcome was OS; secondary outcomes were progression-free survival (PFS) and the objective response rate (ORR). Survival was estimated using the Kaplan-Meier method. Univariate and multivariable Cox regression models are used to estimate the hazard ratio (HR) with 95% confidence interval (CI) for survival outcomes. Subgroup analyses were performed for patients with pancreatic metastases and patients with adrenal metastases. RESULTS AND LIMITATIONS: Among 720 patients treated with nivolumab between February 2016 and July 2017, 217 had GMs, of whom 151/217 had adrenal metastases and 86/217 had pancreatic metastasis. Patients with adrenal metastases had worse 12-mo OS (64% vs 71.1%) and 6-mo PFS (27.2% vs 36.6%) and a lower objective response rate (12.5%, 95% CI 7.6%-19.0%, vs 23.2%, 95% CI 19.8-27.0%; p = 0.005) than patients without adrenal metastases. Conversely, univariate analysis showed that patients with pancreatic metastases had significantly better 12-mo OS (82.3% vs 67.9%; HR 0.59, 95% CI 0.40-0.85) in comparison to patients with nonpancreatic GMs. On multivariable analysis, only adrenal metastasis remained associated with adverse prognosis. CONCLUSIONS: Adrenal metastasis is an independent prognostic factor for poor response and survival in the GETUG-AFU-26 NIVOREN trial. Limited activity with nivolumab was observed for patients with mccRCC with adrenal metastases. These results warrant an evaluation of the prognostic value of adrenal metastases in patients treated with immunotherapy combinations with ipilimumab or tyrosine kinase inhibitors. PATIENT SUMMARY: Our study showed that metastasis in the adrenal glands could be an independent factor associated with poor response to immunotherapy and survival for patients with metastatic kidney cancer. It would be useful to evaluate the prognostic value of adrenal gland metastasis in patients treated with immunotherapy combinations or immunotherapy agents combined with drugs called tyrosine kinase inhibitors.
RESUMEN
BACKGROUND: In metastatic renal clear cell carcinoma (ccRCC), vascular endothelial growth factor receptor (VEGFR) and immune checkpoint are 2 main therapeutic targets. We investigated the impact of duration exposure to antiangiogenic on immunotherapy clinical outcomes in metastatic ccRCC. METHODS: Patients from NIVOREN trial who received nivolumab after only 1 prior antiangiogenic therapy were included. Response rate, clinical benefit, progression free survival (PFS) and overall survival (OS) were prospectively analyzed depending on the duration of the first line (< 6 months, ≥6 months) and exploratory in patients with long first line exposure (≥18 months). The circulating levels of 8 plasma proteins and cytokines at baseline were collected and compared according to first line antiangiogenic duration. RESULTS: Among 354 patients, 127 (36%) and 227 (64%) patients had received first line antiangiogenic for < 6months and ≥ 6months respectively. Respective duration of first line therapy was not associated with objective response to nivolumab (20.5% vs. 23.9%, P = .50), or PFS (HR 0.92; P = .421). Median OS was respectively 16.6 and 31.3 months in the <6 and ≥6 months subgroups respectively. Adjusted on international metastatic renal cell carcinoma database consortium risk, age and metastatic site, OS was longer in patients with longer treatment duration in the first line setting (HR 0.73; P = .017). Duration of first line VEGFR TKI was independent from circulating levels of 8 proteins and cytokines at nivolumab baseline. CONCLUSION: Nivolumab activity in second line is independent from first-line duration of VEGFR TKI. However, first line VEGFR TKI duration ≥ 6 months is associated with longer OS.

INTRODUCTION: Serum prostate specific antigen (PSA) is a well-known prognostic parameter in men with prostate cancer. The treatment of men with very high PSA values and apparently no detectable metastases is not fully established. PATIENTS AND METHODS: Ancillary analysis from the GETUG 12 phase 3 trial. Patients with non-metastatic high-risk prostate cancer by bone and computerized tomography (CT) scan were randomly assigned to receive androgen deprivation therapy (ADT) and docetaxel plus estramustine or ADT alone. Relapse-free survival (RFS), clinical RFS, metastases-free survival (MFS), overall survival (OS), and prostate cancer-specific survival (PCSS) were estimated using the Kaplan-Meier method for different levels of PSA (50 ng/mL, 75 ng/mL, and 100 ng/mL). The relationship between PSA and outcomes was studied using residual-based approaches and spline functions. RESULTS: The median follow-up was 12 years (range: 0-15.3). Baseline PSA (<50 ng/mL, n = 328; ≥50ng/mL, n = 85) was associated with improved RFS (P = .0005), cRFS (P = .0024), and MFS (P = .0068). The 12-year RFS rate was 46.33% (CI 40.59-51.86), 33.59% (CI 22.55-44.97), and 11.76% (1.96-31.20) in men with PSA values <50 ng/mL (n = 328), 50-100 ng/mL (n = 68), and ≥100 ng/mL (n = 17), respectively. Exploratory analyses revealed no deviation from the linear relationship assumption between PSA and the log hazard of events. CONCLUSIONS: Men with apparently localized prostate cancer and a high baseline PSA value have a reasonable chance of being long-term disease-free when treated with curative intent combining systemic and local therapy.

BACKGROUND: Renal medullary carcinoma (RMC) and collecting duct carcinoma (CDC) are rare entities with a poor outcome. First-line metastatic treatment is based on gemcitabine + platinum chemotherapy (GC) regimen but retrospective data suggest enhanced anti-tumour activity with the addition of bevacizumab. Therefore, we performed a prospective assessment of the safety and efficacy of GC + bevacizumab in metastatic RMC/CDC. METHODS: We conducted a phase 2 open-label trial in 18 centres in France in patients with metastatic RMC/CDC and no prior systemic treatment. Patients received bevacizumab plus GC up to 6 cycles followed, for non-progressive disease, by maintenance therapy with bevacizumab until progression or unacceptable toxicity. The co-primary end-points were objective response rates (ORRs) and progression-free survival (PFS) at 6 months (ORR-6; PFS-6). PFS, overall survival (OS) and safety were secondary end-points. At interim analysis, the trial was closed due to toxicity and lack of efficacy. RESULTS: From 2015 to 2019, 34 of the 41 planned patients have been enroled. After a median follow-up of 25 months, ORR-6 and PFS-6 were 29.4% and 47.1%, respectively. Median OS was 11.1 months (95% confidence interval [CI]: 7.6-24.2). Seven patients (20.6%) discontinued bevacizumab because of toxicities (hypertension, proteinuria, colonic perforation). Grade 3-4 toxicities were reported in 82% patients, the most common being haematologic toxicities and hypertension. Two patients experienced grade 5 toxicity (subdural haematoma related to bevacizumab and encephalopathy of unknown origin). CONCLUSION: Our study showed no benefit for bevacizumab added to chemotherapy in metastatic RMC and CDC with higher than expected toxicity. Consequently, GC regimen remains a therapeutic option for RMC/CDC patients.

Neoadjuvant cisplatin-based chemotherapy (NAC) followed by radical cystectomy and pelvic lymph node dissection is the optimal treatment for patients with muscle-invasive bladder cancer. In recent years, the VESPER trial showed a statistically significant higher progression-free survival with dd-MVAC (dose dense methotrexate, vinblastine, doxorubicin, and cisplatin) compared to GC (gemcitabine and cisplatin). In the present report, we refine the characterization and outcome of patients whose cystectomy specimens were pathologically free of cancer (pathological complete response, pCR). We confirm that these patients portend a better outcome as compared to patients with invasive disease (≥pT1N0) at cystectomy. Nested variant and lymphovascular invasion were identified as adverse predictive factors of pCR. Progression-free survival probability three years after pCR on cystectomy was about 85%, regardless of the NAC regimen. A lower creatinine clearance and the delivery of less than four cycles were associated with a higher risk of relapse. Predicting the efficacy of NAC remains a major challenge. The planned analysis of molecular subtypes in the VESPER trial could help predict which patients may achieve complete response and better outcome.
RESUMEN
INTRODUCTION: Bone metastases (BM) in renal cell carcinoma (RCC) are associated with a poor prognosis based on retrospective studies evaluating antiangiogenic agents. Few data are available regarding immune checkpoint inhibitors (ICI) in patients with bone metastatic RCC. NIVOREN is a multicentre prospective study in which patients were treated with nivolumab after the failure of antiangiogenic agents. We aim to assess the impact of BM on prognosis, and the efficacy and safety of nivolumab in patients enrolled in the NIVOREN trial. MATERIALS AND METHODS: All patients with BM at inclusion were included in our study. The primary endpoint was overall survival (OS). Secondary endpoints were progression-free survival (PFS), objective response rate (ORR), safety, and skeletal-related events (SRE). RESULTS: Among 720 patients treated with nivolumab, 194 presented BM at inclusion. The median follow-up was 23.9 months. Median OS was 17.9 months in patients with BM versus 26.1 months in patients without BM (p = 0.0023). The difference was not statistically significant after adjustment (p = 0.0707). The median PFS was shorter in patients with BM even after adjustment (2.8 versus 4.6 months, p = 0.0045), as well as the ORR (14.8% versus 23.3%). SRE occurred for 36% of patients with BM. A post-hoc analysis evaluating the impact of bone-targeting agents (BTA) on SRE incidence showed a significant benefit of BTA on the incidence of SRE (OR = 0.367, CI95% [0.151-0.895]). CONCLUSION: Nivolumab is associated with shorter PFS, and lower ORR in RCC patients with BM. Our study suggests that BTA in association with immunotherapy decreases the incidence of SRE.

BACKGROUND: Pembrolizumab and olaparib have shown single-agent activity in patients with previously treated metastatic castration-resistant prostate cancer (mCRPC). OBJECTIVE: To evaluate the efficacy and safety of pembrolizumab plus olaparib in mCRPC. DESIGN, SETTING, AND PARTICIPANTS: Cohort A of the phase 1b/2 KEYNOTE-365 study enrolled patients with molecularly unselected, docetaxel-pretreated mCRPC whose disease progressed within 6 mo of screening. INTERVENTION: Pembrolizumab 200 mg intravenously every 3 wk plus olaparib 400-mg capsule or 300-mg tablet orally twice daily. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoints were safety, confirmed prostate-specific antigen (PSA) response rate, and objective response rate (ORR) as per Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1, by blinded independent central review. The secondary endpoints included radiographic progression-free survival (rPFS) and overall survival (OS). RESULTS AND LIMITATIONS: Of 104 enrolled patients, 102 were treated. The median age was 70 yr (interquartile range [IQR], 65-76), and 59 patients (58%) had measurable disease as per RECIST v1.1. The median time from the first dose to database cutoff was 24 mo (IQR, 22-47). The confirmed PSA response rate was 15%. The confirmed ORR was 8.5% (five partial responses) for patients with measurable disease. The median rPFS was 4.5 mo (95% confidence interval [CI], 4.0-6.5) and median OS was 14 mo (95% CI, 10.4-18.2). Clinical activity was consistent across the programmed death ligand 1 (PD-L1)-positive and homologous recombination repair mutation subgroups. Treatment-related adverse events (TRAEs) occurred in 93 patients (91%). Grade 3-5 TRAEs occurred in 49 patients (48%). Six deaths (5.9%) were due to adverse events; two (myocardial infarction and unknown cause) were attributed to treatment. Limitations of the study include the single-arm design. CONCLUSIONS: Pembrolizumab plus olaparib had a safety profile consistent with the profiles of the individual agents and demonstrated antitumor activity in previously treated patients with molecularly unselected, docetaxel-pretreated mCRPC. PATIENT SUMMARY: Pembrolizumab plus olaparib showed antitumor activity and expected safety in patients with metastatic castration-resistant prostate cancer.

INTRODUCTION: Proton pump inhibitors (PPI) may influence the gut microbiome and thus impact the effectiveness of immune checkpoint inhibitors (ICI). The effect of PPIs on the outcomes of ICI has not been fully explored and investigated in metastatic renal cell carcinoma (mRCC). METHODS: This retrospective analysis used prospectively collected data from the GETUG-AFU 26 NIVOREN (NCT03013335) phase II study which enrolled 729 mRCC patients of whom 720 were treated with nivolumab. The main objective of this analysis was to evaluate the impact of PPI on the efficacy and safety outcomes of mRCC patients. PPI use was defined as PPI administration on the day of ICI initiation. RESULTS: Of the 707 patients with mRCC analyzed in this study, 196 (27.7%) were PPI users. The majority of PPI users were males (80.6%), had an ECOG performance status of 0-1 (78.9%) and a nephrectomy (82.1%). Almost two-thirds of the patients had a favorable and intermediate IMDC risk category and 52% received nivolumab in the third line and beyond. PPI use did not correlate with PFS or OS (HR = 0.89, 95% CI 0.74-1.08 and HR = 1.24; 95% CI, 0.98-1.58, respectively). Grade 3-5 nivolumab-related adverse events were more common among PPI users (25.5% vs. 15.3%). CONCLUSIONS: This real-world study suggests that PPI use in patients with mRCC does not impact the efficacy outcomes but may influence the safety of nivolumab which warrants further investigations.

AIMS: First described in 2014, renal cell carcinoma (RCC) with TFEB amplification (6p21) is a rare molecular subgroup whose diagnosis is challenging. The prognosis and therapeutic implications remain unclear. METHODS: We report here the clinical, histological, immunohistochemical, and genetic features of nine novel cases. The pathological and immunohistochemical features were centrally reviewed by expert uropathologists. Fluorescence in situ hybridisation (FISH) confirmed the diagnosis and comparative genomic hybridisation (CGH) was performed to determine quantitative genomic alterations. We also performed an exhaustive review of the literature and compiled our data. RESULTS: TFEB-amplified RCC were locally advanced, with initial lymph node involvement in one case and liver metastasis in another case. They were high-grade eosinophilic tumours with papillary/pseudopapillary architecture, frequent positivity for melanocytic markers, and frequent PDL1 expression. FISH demonstrated high-level TFEB amplification in six cases. One case showed concomitant TFEB translocation. CGH analysis identified complex alterations with frequent losses of 1p, 2q, 3p, 6p, and frequent 6p and 8q gains. VEGFA coamplification was identified in all cases with a lower level than TFEB. The prognosis was poor, with five patients having lymph node or distant metastases. CONCLUSION: TFEB-amplified RCC is a rare molecular subgroup with variable morphology whose diagnosis is confirmed by FISH analysis. The complex alterations identified by CGH are consistent with an aggressive clinical behaviour. The coamplification of VEGFA and the expression of PDL1 could suggest a potential benefit from antiangiogenics and targeted immunotherapy in combination for these aggressive tumours.

BACKGROUND: In metastatic seminoma, a strategy is needed for selecting patients for less intensive chemotherapy, to limit toxicities. OBJECTIVE: To assess whether men with good-prognosis metastatic seminoma could be treated with two cycles of etoposide-cisplatin (EP) followed by only one cycle of carboplatin (CARBO) based on negative interim fluorodeoxyglucose positron emission tomography (FDG-PET)/computed tomography (CT). DESIGN, SETTING, AND PARTICIPANTS: A nonrandomised, multicentre, phase 2 trial was conducted (NCT01887340). INTERVENTION: All patients with baseline-positive FDG-PET/CT received EP for two cycles. After completing the first two cycles, the patients underwent a second FDG-PET/CT to assess the response. Patients with positive FDG-PET/CT proceeded directly to two additional EP cycles; those who achieved FDG-PET/CT negativity received one cycle of CARBO. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The proportion of patients with negative interim FDG-PET/CT who received carboplatin was determined. RESULTS AND LIMITATIONS: Between 2013 and 2017, 102 patients were enrolled. After the first two EP cycles, FDG-PET/CT was available in 98 patients. Overall, 67 patients (68.4%; 95% confidence interval [CI]: 58.2-77.4) had negative FDG-PET/CT and proceeded to a single CARBO cycle. Twenty-seven patients (27.6%; 95% CI: 19.0-37.5) had positive FDG-PET/CT after two EP cycles. The 3-yr progression-free survival rate was 90.0% (95% CI: 74.4-96.5) in the EP group and 90.8% (95% CI: 81.4-95.7) in the CARBO group. The cumulative incidences of peripheral neuropathy and ototoxicity were significantly higher in the EP group. CONCLUSIONS: Omission of two cycles of EP based on negative FDG-PET/CT after two cycles of chemotherapy appears to be feasible. However, the absence of consensus criteria for FDG-PET/CT interpretation and the short follow-up need additional studies. This strategy does not warrant routine integration yet. PATIENT SUMMARY: Men with good-prognosis metastatic seminoma were treated with fewer cycles of chemotherapy based on interim fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT). Omission of two cycles of chemotherapy based on negative FDG-PET/CT after two initial cycles appears to be feasible, thereby limiting the burden of treatment and toxicity.

Collecting duct carcinoma (CDC) and renal medullary carcinoma (RMC) are two rare subtypes of kidney cancer with a poor prognosis in the metastatic setting. Beyond first-line treatment, there are no standard-of-care therapies. This retrospective study assessed the efficacy of treatments after first-line chemotherapy in 57 patients with metastatic (m) CDC (n = 35) or RMC (n = 22) treated between 2010 and 2019 at 11 French centers. The median age was 53 years; overall, 60% (n = 34) of patients were metastatic at diagnosis. After a median follow-up of 13 months, the median overall survival was 12 (95% CI, 11−16) months. All patients received first-line platinum chemotherapy ± bevacizumab, with a median time to progression of 7.27 (95% CI, 7−100 months and an objective response rate (ORR) of 39% (95% CI, 26−52%). Patients received a median of two (1−5) treatment lines. Subsequent treatments included tyrosine kinase inhibitors (n = 12), chemotherapy (n = 34), and checkpoint inhibitors (n = 20), with ORR ranging 10−15% and disease control rates ranging 24−50%. The duration of response for all treatments was ~2 months. Notably, nine patients with CDC were still alive > two years after metastatic diagnosis. Beyond first-line therapy, treatments showed very low antitumor activity in mCDC/RMC. A better understanding of the biology of those rare tumors is urgently needed in order to identify potential targets.
RESUMEN
BACKGROUND: We previously reported a 35-gene expression classifier identifying four clear-cell renal cell carcinoma groups (ccrcc1 to ccrcc4) with different tumour microenvironments and sensitivities to sunitinib in metastatic clear-cell renal cell carcinoma. Efficacy profiles might differ with nivolumab and nivolumab-ipilimumab. We therefore aimed to evaluate treatment efficacy and tolerability of nivolumab, nivolumab-ipilimumab, and VEGFR-tyrosine kinase inhibitors (VEGFR-TKIs) in patients according to tumour molecular groups. METHODS: This biomarker-driven, open-label, non-comparative, randomised, phase 2 trial included patients from 15 university hospitals or expert cancer centres in France. Eligible patients were aged 18 years or older, had an Eastern Cooperative Oncology Group performance status of 0-2, and had previously untreated metastatic clear-cell renal cell carcinoma. Patients were randomly assigned (1:1) using permuted blocks of varying sizes to receive either nivolumab or nivolumab-ipilimumab (ccrcc1 and ccrcc4 groups), or either a VEGFR-TKI or nivolumab-ipilimumab (ccrcc2 and ccrcc3 groups). Patients assigned to nivolumab-ipilimumab received intravenous nivolumab 3 mg/kg plus ipilimumab 1 mg/kg every 3 weeks for four doses followed by intravenous nivolumab 240 mg every 2 weeks. Patients assigned to nivolumab received intravenous nivolumab 240 mg every 2 weeks. Patients assigned to VEGFR-TKIs received oral sunitinib (50 mg/day for 4 weeks every 6 weeks) or oral pazopanib (800 mg daily continuously). The primary endpoint was the objective response rate by investigator assessment per Response Evaluation Criteria in Solid Tumors version 1.1. The primary endpoint and safety were assessed in the population who received at least one dose of study drug. This trial is registered with ClinicalTrials.gov, NCT02960906, and with the EU Clinical Trials Register, EudraCT 2016-003099-28, and is closed to enrolment. FINDINGS: Between June 28, 2017, and July 18, 2019, 303 patients were screened for eligibility, 202 of whom were randomly assigned to treatment (61 to nivolumab, 101 to nivolumab-ipilimumab, 40 to a VEGFR-TKI). In the nivolumab group, two patients were excluded due to a serious adverse event before the first study dose and one patient was excluded from analyses due to incorrect diagnosis. Median follow-up was 18·0 months (IQR 17·6-18·4). In the ccrcc1 group, objective responses were seen in 12 (29%; 95% CI 16-45) of 42 patients with nivolumab and 16 (39%; 24-55) of 41 patients with nivolumab-ipilimumab (odds ratio [OR] 0·63 [95% CI 0·25-1·56]). In the ccrcc4 group, objective responses were seen in seven (44%; 95% CI 20-70) of 16 patients with nivolumab and nine (50% 26-74) of 18 patients with nivolumab-ipilimumab (OR 0·78 [95% CI 0·20-3·01]). In the ccrcc2 group, objective responses were seen in 18 (50%; 95% CI 33-67) of 36 patients with a VEGFR-TKI and 19 (51%; 34-68) of 37 patients with nivolumab-ipilimumab (OR 0·95 [95% CI 0·38-2·37]). In the ccrcc3 group, no objective responses were seen in the four patients who received a VEGFR-TKI, and in one (20%; 95% CI 1-72) of five patients who received nivolumab-ipilimumab. The most common treatment-related grade 3-4 adverse events were hepatic failure and lipase increase (two [3%] of 58 for both) with nivolumab, lipase increase and hepatobiliary disorders (six [6%] of 101 for both) with nivolumab-ipilimumab, and hypertension (six [15%] of 40) with a VEGFR-TKI. Serious treatment-related adverse events occurred in two (3%) patients in the nivolumab group, 38 (38%) in the nivolumab-ipilimumab group, and ten (25%) patients in the VEGFR-TKI group. Three deaths were treatment-related: one due to fulminant hepatitis with nivolumab-ipilimumab, one death from heart failure with sunitinib, and one due to thrombotic microangiopathy with sunitinib. INTERPRETATION: We demonstrate the feasibility and positive effect of a prospective patient selection based on tumour molecular phenotype to choose the most efficacious treatment between nivolumab with or without ipilimumab and a VEGFR-TKI in the first-line treatment of metastatic clear-cell renal cell carcinoma.
