RESUMO
BACKGROUND: Nivolumab plus ipilimumab is approved as first-line regimen for intermediate-risk or poor-risk metastatic renal cell carcinoma, and nivolumab monotherapy as second-line therapy for all risk groups. We aimed to examine the efficacy and safety of nivolumab monotherapy and nivolumab plus ipilimumab combination as an immunotherapeutic boost after no response to nivolumab monotherapy in patients with intermediate-risk and poor-risk clear-cell metastatic renal cell carcinoma. METHODS: TITAN-RCC is a multicentre, single-arm, phase 2 trial, done at 28 hospitals and cancer centres across Europe (Austria, Belgium, Czech Republic, France, Germany, Italy, Spain, and the UK). Adults (aged ≥18 years) with histologically confirmed intermediate-risk or poor-risk clear-cell metastatic renal cell carcinoma who were formerly untreated (first-line population) or pretreated with one previous systemic therapy (anti-angiogenic or temsirolimus; second-line population) were eligible. Patients had to have a Karnofsky Performance Status score of at least 70 and measurable disease per Response Evaluation Criteria in Solid Tumours (version 1.1). Patients started with intravenous nivolumab 240 mg once every 2 weeks. On early progressive disease (week 8) or non-response at week 16, patients received two or four doses of intravenous nivolumab (3 mg/kg) and ipilimumab (1 mg/kg) boosts (once every 3 weeks), whereas responders continued with intravenous nivolumab (240 mg, once every 2 weeks), but could receive two to four boost doses of nivolumab plus ipilimumab for subsequent progressive disease. The primary endpoint was confirmed investigator-assessed objective response rate in the full analysis set, which included all patients who received at least one dose of study medication; safety was also assessed in this population. An objective response rate of more than 25% was required to reject the null hypothesis and show improvement, on the basis of results from the pivotal phase 3 CheckMate-025 trial. This study is registered with ClinicalTrials.gov, NCT02917772, and is complete. FINDINGS: Between Oct 28, 2016, and Nov 30, 2018, 207 patients were enrolled and all received nivolumab induction (109 patients in the first-line group; 98 patients in the second-line group). 60 (29%) of 207 patients were female and 147 (71%) were male. 147 (71%) of 207 patients had intermediate-risk metastatic renal cell carcinoma and 51 (25%) had poor-risk disease. After median follow-up of 27·6 months (IQR 10·5-34·8), 39 (36%, 90% CI 28-44; p=0·0080) of 109 patients in the first-line group and 31 (32%, 24-40; p=0·083) of 98 patients in the second-line group had a confirmed objective response for nivolumab with and without nivolumab plus ipilimumab. Confirmed response to nivolumab at week 8 or 16 was observed in 31 (28%) of 109 patients in the first-line group and 18 (18%) of 98 patients in the second-line group. The most frequent grade 3-4 treatment-related adverse events (reported in ≥5% of patients) were increased lipase (15 [7%] of 207 patients), colitis (13 [6%]), and diarrhoea (13 [6%]). Three deaths were reported that were deemed to be treatment-related: one due to possible ischaemic stroke, one due to respiratory failure, and one due to pneumonia. INTERPRETATION: In treatment-naive patients, nivolumab induction with or without nivolumab plus ipilimumab boosts significantly improved the objective response rate compared with that reported for nivolumab monotherapy in the CheckMate-025 trial. However, overall efficacy seemed inferior when compared with approved upfront nivolumab plus ipilimumab. For second-line treatment, nivolumab plus ipilimumab could be a rescue strategy on progression with approved nivolumab monotherapy. FUNDING: Bristol Myers Squibb.

BACKGROUND: Current standard of care for metastatic castration-sensitive prostate cancer supplements androgen deprivation therapy with either docetaxel, second-generation hormonal therapy, or radiotherapy. We aimed to evaluate the efficacy and safety of abiraterone plus prednisone, with or without radiotherapy, in addition to standard of care. METHODS: We conducted an open-label, randomised, phase 3 study with a 2 × 2 factorial design (PEACE-1) at 77 hospitals across Belgium, France, Ireland, Italy, Romania, Spain, and Switzerland. Eligible patients were male, aged 18 years or older, with histologically confirmed or cytologically confirmed de novo metastatic prostate adenocarcinoma, and an Eastern Cooperative Oncology Group performance status of 0-1 (or 2 due to bone pain). Participants were randomly assigned (1:1:1:1) to standard of care (androgen deprivation therapy alone or with intravenous docetaxel 75 mg/m2 once every 3 weeks), standard of care plus radiotherapy, standard of care plus abiraterone (oral 1000 mg abiraterone once daily plus oral 5 mg prednisone twice daily), or standard of care plus radiotherapy plus abiraterone. Neither the investigators nor the patients were masked to treatment allocation. The coprimary endpoints were radiographic progression-free survival and overall survival. Abiraterone efficacy was first assessed in the overall population and then in the population who received androgen deprivation therapy with docetaxel as standard of care (population of interest). This study is ongoing and is registered with ClinicalTrials.gov, NCT01957436. FINDINGS: Between Nov 27, 2013, and Dec 20, 2018, 1173 patients were enrolled (one patient subsequently withdrew consent for analysis of his data) and assigned to receive standard of care (n=296), standard of care plus radiotherapy (n=293), standard of care plus abiraterone (n=292), or standard of care plus radiotherapy plus abiraterone (n=291). Median follow-up was 3·5 years (IQR 2·8-4·6) for radiographic progression-free survival and 4·4 years (3·5-5·4) for overall survival. Adjusted Cox regression modelling revealed no interaction between abiraterone and radiotherapy, enabling the pooled analysis of abiraterone efficacy. In the overall population, patients assigned to receive abiraterone (n=583) had longer radiographic progression-free survival (hazard ratio [HR] 0·54, 99·9% CI 0·41-0·71; p<0·0001) and overall survival (0·82, 95·1% CI 0·69-0·98; p=0·030) than patients who did not receive abiraterone (n=589). In the androgen deprivation therapy with docetaxel population (n=355 in both with abiraterone and without abiraterone groups), the HRs were consistent (radiographic progression-free survival 0·50, 99·9% CI 0·34-0·71; p<0·0001; overall survival 0·75, 95·1% CI 0·59-0·95; p=0·017). In the androgen deprivation therapy with docetaxel population, grade 3 or worse adverse events occurred in 217 (63%) of 347 patients who received abiraterone and 181 (52%) of 350 who did not; hypertension had the largest difference in occurrence (76 [22%] patients and 45 [13%], respectively). Addition of abiraterone to androgen deprivation therapy plus docetaxel did not increase the rates of neutropenia, febrile neutropenia, fatigue, or neuropathy compared with androgen deprivation therapy plus docetaxel alone. INTERPRETATION: Combining androgen deprivation therapy, docetaxel, and abiraterone in de novo metastatic castration-sensitive prostate cancer improved overall survival and radiographic progression-free survival with a modest increase in toxicity, mostly hypertension. This triplet therapy could become a standard of care for these patients. FUNDING: Janssen-Cilag, Ipsen, Sanofi, and the French Government.

BACKGROUND: Early risk-stratified chemotherapy is a standard treatment for breast, colorectal, and lung cancers, but not for high-risk localised prostate cancer. Combined docetaxel and estramustine improves survival in patients with castration-resistant prostate cancer. We assessed the effects of combined docetaxel and estramustine on relapse in patients with high-risk localised prostate cancer. METHODS: We did this randomised phase 3 trial at 26 hospitals in France. We enrolled patients with treatment-naive prostate cancer and at least one risk factor (ie, stage T3-T4 disease, Gleason score of ≥8, prostate-specific antigen concentration >20 ng/mL, or pathological node-positive). All patients underwent a staging pelvic lymph node dissection. Patients were randomly assigned (1:1) to either androgen deprivation therapy (ADT; goserelin 10·8 mg every 3 months for 3 years) plus four cycles of docetaxel on day 2 at a dose of 70 mg/m(2) and estramustine 10 mg/kg per day on days 1-5, every 3 weeks, or ADT only. The randomisation was done centrally by computer, stratified by risk factor. Local treatment was administered at 3 months. Neither patients nor investigators were masked to treatment allocation. The primary endpoint was relapse-free survival in the intention-to-treat population. Follow-up for other endpoints is ongoing. This study is registered with ClinicalTrials.gov, number NCT00055731. FINDINGS: We randomly assigned 207 patients to the ADT plus docetaxel and estramustine group and 206 to the ADT only group. Median follow-up was 8·8 years (IQR 8·1-9·7). 88 (43%) of 207 patients in the ADT plus docetaxel and estramustine group had an event (relapse or death) versus 111 (54%) of 206 in the ADT only group. 8-year relapse-free survival was 62% (95% CI 55-69) in the ADT plus docetaxel and estramustine group versus 50% (44-57) in the ADT only group (adjusted hazard ratio [HR] 0·71, 95% CI 0·54-0·94, p=0·017). Of patients who were treated with radiotherapy and had data available, 31 (21%) of 151 in the ADT plus docetaxel and estramustine group versus 26 (18%) of 143 in the ADT only group reported a grade 2 or higher long-term side-effect (p=0·61). We recorded no excess second cancers (26 [13%] of 207 vs 22 [11%] of 206; p=0·57), and there were no treatment-related deaths. INTERPRETATION: Docetaxel-based chemotherapy improves relapse-free survival in patients with high-risk localised prostate cancer. Longer follow-up is needed to assess whether this benefit translates into improved metastasis-free survival and overall survival.

BACKGROUND: Preclinical studies demonstrated that non-nucleoside reverse transcriptase inhibitors used for the treatment of HIV could antagonize tumor development. This led us to assess the efficacy of efavirenz in patients with metastatic castration-resistant prostate cancer (mCRPC) in a multicenter phase II study. METHODS: We used a Simon two-stage design and a 3-month prostate-specific antigen (PSA) nonprogression rate of 40% as a primary objective. Patients received 600 mg efavirenz daily with the possibility of a dose increase in case of PSA progression. Exploratory analyses included pharmacokinetics of efavirenz plasma concentrations and correlations with clinical outcomes. RESULTS: Among 53 assessable patients, we observed 15 instances of PSA nonprogression at 3 months, corresponding to a nonprogression rate of 28.3% (95% confidence interval: 16.8%-42.3%). The exploratory analysis revealed that for the 7 patients in whom optimal plasma concentration of efavirenz was achieved, PSA progression was observed in only 28.6% compared with 81.8% of patients with suboptimal plasma concentrations of efavirenz. CONCLUSION: Although 600 mg efavirenz did not statistically improve the PSA nonprogression rate, our exploratory analysis suggests that higher plasma concentrations of this drug (i.e., use of increased dosages) may be of potential benefit for the treatment of mCRPC.

BACKGROUND AND OBJECTIVE: Docetaxel has become a standard component of care for advanced prostate cancer (PC); however, its benefits are not universal among patients. A subset of PC cases exhibit TMPRSS2-ERG gene fusion, resulting in ERG overexpression in tumors. Our aim was to assess biomarkers for docetaxel efficacy in men with hormone-sensitive PC (HSPC). METHODS: Pretreatment prostate biopsies were obtained from participants in two randomized phase 3 clinical trials investigating docetaxel in high-risk localized PC (GETUG 12) and metastatic HSPC (GETUG 15). Immunohistochemistry staining for Ki67, PTEN, RB, and phosphorylated RB was conducted for GETUG 12 samples, and ERG staining for GETUG 12 and GETUG 15 samples. We examined biomarker association with outcomes using univariate and multivariable analyses adjusted for other validated prognostic factors. KEY FINDINGS AND LIMITATIONS: Among GETUG 12 patients, Ki67 was associated with a worse relapse-free survival (RFS; hazard ratio [HR] 1.72; p = 0.0092). A pooled analysis for the two trials (pinteraction = 0.056) revealed that docetaxel-based chemotherapy improved failure-free survival for patients with ERG-positive cancer (HR 0.58; p = 0.03), but not patients with ERG-negative cancer (HR 1.08; p = 0.72). In the ERG-positive subgroup in GETUG 12 (high-risk localized PC), median RFS was 7.79 yr with androgen deprivation therapy (ADT) alone, and was not reached with ADT + docetaxel. In the ERG-negative subgroup, median progression-free survival (mPFS) was 7.79 yr with ADT alone versus 7.08 yr with ADT + docetaxel. In the ERG-positive subgroup in GETUG 15 (metastatic HSPC), mPFS was 10.7 mo with ADT alone versus 18.8 mo with ADT + docetaxel. In the ERG-negative subgroup, mPFS was 10.6 mo with ADT alone versus 13.2 mo with ADT + docetaxel. CONCLUSIONS AND CLINICAL IMPLICATIONS: Ki67 may serve as a prognostic factor in HSPC, while ERG expression appears to predict a response to docetaxel in both high-risk localized and metastatic HSPC. PATIENT SUMMARY: We assessed factors that could predict outcomes after docetaxel chemotherapy in patients with advanced prostate cancer. We found that expression of a protein called ERG can predict a good response to docetaxel in these patients.
RESUMO
This open-label, non-comparative, 2:1 randomized, phase II trial (NCT03275506) in women with stage IIIC/IV high-grade serous carcinoma (HGSC) for whom upfront complete resection was unachievable assessed whether adding pembrolizumab (200 mg every 3 weeks) to standard-of-care carboplatin plus paclitaxel yielded a complete resection rate (CRR) of at least 50%. Postoperatively patients continued assigned treatment for a maximum of 2 years. Postoperative bevacizumab was optional. The primary endpoint was independently assessed CRR at interval debulking surgery. Secondary endpoints were Completeness of Cytoreduction Index (CCI) and peritoneal cancer index (PCI) scores, objective and best response rates, progression-free survival, overall survival, safety, postoperative morbidity, and pathological complete response. The CRR in 61 pembrolizumab-treated patients was 74% (one-sided 95% CI = 63%), exceeding the prespecified ≥50% threshold and meeting the primary objective. The CRR without pembrolizumab was 70% (one-sided 95% CI = 54%). In the remaining patients CCI scores were ≥3 in 27% of the standard-of-care group and 18% of the investigational group and CC1 in 3% of the investigational group. PCI score decreased by a mean of 9.6 in the standard-of-care group and 10.2 in the investigational group. Objective response rates were 60% and 72%, respectively, and best overall response rates were 83% and 90%, respectively. Progression-free survival was similar with the two regimens (median 20.8 versus 19.4 months in the standard-of-care versus investigational arms, respectively) but overall survival favored pembrolizumab-containing therapy (median 35.3 versus 49.8 months, respectively). The most common grade ≥3 adverse events with pembrolizumab-containing therapy were anemia during neoadjuvant therapy and infection/fever postoperatively. Pembrolizumab was discontinued prematurely because of adverse events in 23% of pembrolizumab-treated patients. Combining pembrolizumab with neoadjuvant chemotherapy is feasible for HGSC considered not completely resectable; observed activity in some subgroups justifies further evaluation to improve understanding of the role of immunotherapy in HGSC.

Geriatric assessment (GA) can predict and improve treatment tolerance and estimate overall survival in older patients with cancer. Several international organizations promote GA; however, data related to its implementation in daily clinical practice are still limited. We aimed to describe GA implementation in patients over 75 years old with metastatic prostate cancer treated with docetaxel as first-line treatment, and with positive G8 screening test or frailty criteria. This retrospective real-world study included 224 patients treated from 2014 to 2021 in four French centers, including 131 patients with a theoretical indication of GA. Among the latter, 51 (38.9%) patients had GA. The main barriers to GA were the lack of systematic screening (32/80, 40.0%), unavailability of geriatric physician (20/80, 25.0%), and absence of referral despite a positive screening test (12/80, 15.0%). With GA performed in only one-third of the patients with a theoretical indication in daily clinical practice, mostly due to an absence of screening test, the use of GA is currently sub-optimal.
RESUMO
BACKGROUND: In patients with metastatic castration-resistant prostate cancer, darolutamide was well tolerated for 25 months, but minimal long-term safety data are available. METHODS: Treatment-emergent adverse events (TEAEs) for patients receiving darolutamide for a median of 38 months (n = 13) are described in this pooled analysis of individual patient data from phase 1/2 studies. RESULTS: All patients reported TEAEs (mostly grade 1/2). The most common TEAEs were diarrhea, abdominal pain, and nausea. Serious TEAEs were reported in six patients (none related to darolutamide). All treatment-related TEAEs (n = 5) were grade 1. CONCLUSIONS: Long-term darolutamide treatment was well tolerated; no new safety signals observed. In patients with mCRPC, long-term darolutamide treatment was well tolerated and no new safety signals were observed. These findings are consistent with previous reports, demonstrating a favorable safety and tolerability profile of darolutamide.
RESUMO
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.
RESUMO
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.

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: Vascular endothelial growth factor (VEGF) has a crucial role in angiogenesis, and is a valid target in metastatic breast cancer. Motesanib is an investigational oral inhibitor of VEGF receptors. We aimed to determine whether treatment with motesanib plus paclitaxel is better than placebo plus paclitaxel in patients with HER2-negative locally recurrent or metastatic breast cancer. METHODS: Between Dec 1, 2006, and July 4, 2008, patients with untreated HER2-negative metastatic breast cancer were randomly assigned (using a randomisation list created by personnel not associated with the study) in a 1:1:1 ratio to paclitaxel (90 mg/m(2) on days 1, 8, and 15 every 3 weeks) plus either masked motesanib 125 mg orally once per day (n=91), masked placebo orally once per day (n=94), or open-label bevacizumab 10 mg/kg intravenously on days 1 and 15 of each 28-day cycle (n=97), after stratification according to adjuvant or neoadjuvant chemotherapy (taxane-containing regimens vs other regimens vs none), number of metastatic sites (<3 vs ≥3), and hormone receptor status (positive vs negative). Placebo was provided as a replica of motesanib 25 mg tablets. The primary endpoint was objective response rate (ORR) based on the population as assigned to treatment. This trial is registered with ClinicalTrials.gov, number NCT00356681. FINDINGS: ORRs for the motesanib group and the placebo group did not differ significantly (49%vs 41%; absolute difference 8% [95% CI -6 to 22]; p=0.31). The ORR in the bevacizumab group (52%) was similar to that in the motesanib group. The most common grade 3 or higher adverse events included diarrhoea (18 of 92 patients in the motesanib group, none of 89 patients in the placebo group, and four of 96 patients in the bevacizumab group), fatigue (11, eight, and six), hypertension (11, one, and seven), and peripheral sensory neuropathy (ten, seven, and 19). More patients in the motesanib group had serious adverse events than did those in the placebo or bevacizumab groups (34, 26, and 21 patients, respectively); the most common of these in the motesanib group were gastrointestinal in nature.

BACKGROUND: Docetaxel (DOCE) is a standard of care in metastatic castration-resistant prostate cancer (mCRPC). Several retrospective studies suggested a decrease in Prostate Cancer incidence and mortality with metformin (MET). MET has also demonstrated anti-tumor activity in Prostate Cancer preclinical models, with increased apoptosis when added to DOCE. We aimed at exploring the role of MET in combination with DOCE in mCRPC. PATIENTS AND METHODS: Non-diabetic mCRPC patients were randomly assigned to receive DOCE 75 mg/m2 every 21 days + prednisone (5 mg. BID) with either MET 850 mg BID (D+M) or placebo (D+P) up to 10 cycles. Prostate-Specific Antigen (PSA) response ≥50% from baseline was the primary end point. Secondary end points included objective response rate (ORR), progression-free survival (PFS), overall survival (OS), toxicity and quality of life (QoL). RESULTS: Out of 99 patients were randomized (D+M = 50; D+P = 49) in 10 French centers. The median follow-up was 86 (IQR 73-88) months. The PSA-response rate reached 66% in the D+M arm, but was not different from that observed in the D+P arm (63%, P = 0,94). In the D+M and D+P arms, the ORR was 28% and 24%, the median PFS was 7.8 and 6.0 months and the median OS was 27 and 20 months (ns), respectively. Diarrhea grade I to II was more frequent in the MET arm (66% vs. 43%). No impairment of QoL was observed. CONCLUSION: MET addition failed to improve the standard DOCE regimen in mCRPC. Further research targeting tumor cell metabolism should be performed.

OBJECTIVES: In 2016, the European Society of Gynecology Oncology (ESGO) published indicators defining the quality of surgical management of advanced ovarian cancer. The objective of the study was to assess the quality of ovarian cancer patient management in regional centers authorized for gynecological cancer, based on the ESGO list of quality indicators. METHODS: A multicenter retrospective observational cohort study was conducted from January 1 to June 30, 2016. The following quality indicators 1 "rate of complete surgical resection", 4 "center participating in clinical trials in gynecologic oncology", 5 "treatment planned and reviewed at a multidisciplinary team meeting", 6 "required preoperative workup", 8 "minimum required elements in operative reports" and 9 "minimum required elements in pathology reports" were selected. RESULTS: 91 patients were evaluated in 16 centers. The required preoperative workup was incomplete in 25% of cases. Treatment was not planned at a multidisciplinary team meeting for 24%. An evaluation score of peritoneal involvement was included in 40% of the operative reports and the quality of surgical resection was reported in 72%. Primary surgery was most often performed in a peripheral hospital (48%), interval surgery in a private center (37%), and closure surgery in a regional cancer center (43%). No institution respected the six quality indicators evaluated. One regional cancer center respected five items and two private centers did not respect any. CONCLUSION: Whilst the ESGO quality indicators provide objective, validated and evaluable support which centers can use to improve quality of care, we observed heterogeneous practices amongst the centers evaluated.

BACKGROUND: Cabazitaxel was shown to improve overall survival (OS) in patients with metastatic castration-resistant prostate cancer (mCRPC) after abiraterone/enzalutamine and docetaxel failure, though benefit by the presence of DNA damage repair (DDR) defects is unknown. With the advent of poly(adenosine diphosphate-ribose) polymerase inhibitors (PARPi) in partially overlapping indications with cabazitaxel, we aimed to determine cabazitaxel activity in men with mCRPC according to their DDR status. METHODS: This is a retrospective multicenter study that enrolled patients with mCRPC treated with cabazitaxel who had undergone DDR tumour tissue profiling. Patients with at least one deleterious germline or somatic alterations were considered DDR positive (DDR+). Each DDR + patient has been matched with a DDR negative (DDR-) from the same institution who underwent the same test. An exploratory cohort of patients found to be DDR + by liquid biopsy was also included. Prostate specific antigen (PSA) decline≥50% (PSA50), PSA progression-free survival (PFS, PSA-PFS), radiographic PFS (rPFS), clinical PFS or radiographic PFS (c/rPFS) and OS were evaluated. RESULTS: Among 190 men (95 DDR+, 95 DDR-) with tissue sequencing, PSA50 was achieved with cabazitaxel in 29/92 (32%) and 33/92 (36%) in patients with DDR+ and DDR- (P = 0.64). The median rPFS was 5.33 months [95%CI 4.34-7.04] versus 5.75 months [95%CI 4.67-7.27] (P = 0.55). The median OS was 15.4 months [95%CI 12.16-26.6] and 11.5 months [95%CI 9.76-14.4] (P = 0.036), respectively. No PSA50 responses on cabazitaxel were observed in BRCA1/2 patients previously treated with PARPi (n = 10). Similar outcomes with cabazitaxel were observed in the liquid biopsy cohort (n = 63 DDR+). CONCLUSIONS: Our study suggests that cabazitaxel is active in patients with mCRPC regardless of their DDR status, although its activity in men pretreated with a PARPi may be lower.

OBJECTIVE: To investigate the potential benefit of reintroducing docetaxel chemotherapy in patients with progressive metastatic castration-resistant prostate cancer (mCRPC) who had initially responded to first-line docetaxel-based regimen. PATIENTS AND METHODS: Records were evaluated retrospectively from French patients with mCRPC who had been included in seven controlled clinical studies of docetaxel as first-line treatment. We identified patients who were confirmed as responders to first-line treatment, discontinued for reasons other than disease progression or unacceptable toxicity, and who received further docetaxel chemotherapy for disease progression. The primary objective was to assess efficacy in terms of the prostate-specific antigen (PSA) response after resuming a docetaxel-based chemotherapy. Secondary objectives were overall survival and tolerance. RESULTS: Of the 148 patients who responded to first-line docetaxel, 50 received further therapy with docetaxel and were analysed. The median (range) response duration to first-line docetaxel was 10.3 (4.6-45.7) months and the median docetaxel-free interval was 18.4 (5.0-46.7) months. Docetaxel was reintroduced as second-line therapy in 52% of patients and as further lines in 48%. After docetaxel reintroduction, 24 patients (48%) had a 50% decrease in PSA level (95% confidence interval, CI, 34.1-61.8%). The median (95% CI) overall survival from docetaxel reintroduction was 16 (13-20) months. Re-treatment was well tolerated (6% of grade 3-4 haemotoxicity). CONCLUSION: Docetaxel reintroduction appears to be effective, with favourable tolerance profiles, in patients with mCRPC having responded to first-line docetaxel, and should be prospectively assessed in clinical trials against alternative therapies or investigational agents given alone or in combination, to define further management.

AIM OF THE STUDY: Our goal was to evaluate the impact of progression type (prostate-specific antigen [PSA] only, radiological or clinical) at initiation of first-, second- and third life-extending therapy (LET) on treatment outcomes in metastatic castration-resistant prostate cancer (mCRPC) patients, by performing a post-hoc analysis using data from the CATS international registry. METHODS: The 669 consecutive mCRPC patients of the CATS registry were classified according to their type of progression at initiation of each LET: PSA only (PSA-p), radiological (±PSA) (Radio-p); or clinical (±PSA, ±radiological) progression (Clin-p). Overall survival (OS), the primary endpoint, was calculated from initiation of the first-, second- and third-LET to death for each sequence. RESULTS: Median OS was shorter in the Clin-p group compared with the PSA-p group (14-month difference in first line; around 7-month difference in second- and third line). Shorter progression-free survival (PFS) was also observed in Clin-p patients, whatever the treatment is. Clinical progression seemed to be associated with a shorter duration of therapy with androgen receptor-targeted therapy (ART) compared with taxanes. CONCLUSIONS: Clinical progression at initiation of a LET is associated with poor outcomes including shorter PFS and OS as well as clinical and biological features of aggressive disease. Stratifying patients in clinical trials according to disease progression type may prevent selection bias and data heterogeneity. In daily practice, first signs of clinical progression may prompt physicians to consider starting a new LET, independently of PSA levels.

PURPOSE: PROSTVAC, a viral vector-based immunotherapy, prolonged median overall survival (OS) by 8.5 months versus placebo in metastatic castration-resistant prostate cancer in a phase II study. This phase III study further investigated those findings. PATIENTS AND METHODS: Patients were randomly assigned to PROSTVAC (Arm V; n = 432), PROSTVAC plus granulocyte-macrophage colony-stimulating factor (Arm VG; n = 432), or placebo (Arm P; n = 433), stratified by prostate-specific antigen (less than 50 ng/mL v 50 ng/mL or more) and lactate dehydrogenase (less than 200 v 200 U/L or more). Primary end point was OS. Secondary end points were patients alive without events (AWE)-namely, radiographic progression, pain progression, chemotherapy initiation, or death-at 6 months and safety. The study design was a superiority trial of PROSTVAC (Arm V or Arm VG) versus Arm P. Three interim analyses were planned. RESULTS: At the third interim analysis, criteria for futility were met and the trial was stopped early. Neither active treatment had an effect on median OS (Arm V, 34.4 months; hazard ratio, 1.01; 95% CI, 0.84 to 1.20; P = .47; Arm VG, 33.2 months; hazard ratio, 1.02; 95% CI, 0.86 to 1.22; P = .59; Arm P, 34.3 months). Likewise, AWE at 6 months was similar (Arm V, 29.4%; odds ratio, 0.96; 95% CI, 0.71 to 1.29; Arm VG, 28.0%; odds ratio, 0.89; 95% CI, 0.66 to 1.20; placebo, 30.3%). Adverse events were similar for the treatment and placebo groups, with the most common being injection site reactions (62% to 72%) and fatigue (21% to 24%). Arrhythmias were the most common cardiac-related events (1.4% to 3.5%). There were no reports of either myocarditis or pericarditis. Serious treatment-related events occurred in less than 1% of all patients. CONCLUSION: Whereas PROSTVAC was safe and well tolerated, it had no effect on OS or AWE in metastatic castration-resistant prostate cancer. Combination therapy is currently being explored in clinical trials.

PURPOSE: Nivolumab is standard of care for patients with metastatic clear cell renal cell carcinoma (ccRCC) after failure of antiangiogenic therapies, but its activity on brain metastases from ccRCC remains unknown, because these patients were excluded from pivotal studies. We aimed to assess the activity of nivolumab in this population. METHODS: The GETUG-AFU 26 NIVOREN phase II trial assessed the activity and safety of nivolumab in patients with metastatic ccRCC who failed vascular endothelial growth factor-directed therapies (ClinicalTrials.gov identifier: NCT03013335). Patients with asymptomatic brain metastases were prospectively identified and underwent dedicated brain evaluation. Two cohorts were constituted: cohort A comprised patients with previously untreated brain metastases, and cohort B comprised patients whose brain metastases underwent prior therapy. The primary end point was intracranial response rate in cohort A. RESULTS: Seventy-three patients with brain metastases were included: 39 in cohort A and 34 in cohort B. Intracranial response rate was 12% in cohort A; no objective response was reported in patients with brain lesions that were multiple or larger than 1 cm. Median intracranial progression-free survival was 2.7 months (95% CI, 2.3 to 4.6 months) in cohort A and 4.8 months (95% CI, 3.0 to 8.0 months) in cohort B, with adjusted hazard ratio of 2.04 (95% CI, 1.08 to 3.83). Overall survival rate at 12 months was 67% (95% CI, 49.6% to 79.1%) in cohort A and 59% (95% CI, 40.6% to 73.2%) in cohort B. Most patients in cohort A (72%) needed subsequent focal brain therapy. Nivolumab was well tolerated, with no unexpected toxicity. CONCLUSION: Nivolumab activity is limited in patients with untreated brain metastases from ccRCC. Brain imaging and focal therapy should be considered before immune checkpoint inhibitors in patients with metastatic ccRCC.
