297 Background: Phase III clinical trials have demonstrated efficacy with an overall survival (OS) benefit for the addition of docetaxel (DOC) to androgen deprivation therapy (ADT) for the treatment of metastatic castration-sensitive prostate cancer (mCSPC). The clinical effectiveness of DOC with ADT in the general patient population remains undefined. Methods: A population-based retrospective review was conducted of patients (pts) with mCSPC who received DOC at the BC Cancer Agency from 04/2015 to 02/2017. Patient and disease characteristics were extracted. Safety and clinical-effectiveness were evaluated. Results: 183 records were identified; 156 pts received DOC in the mCSPC setting. Baseline characteristics included a median age of 67 years (range 44-86) and visceral metastases (mets) present in 18%; 80% had high volume disease with 74% having > 3, and 54% > 10 bone mets; 76% had de-novo metastatic disease. All 6 planned DOC cycles were delivered in 126 cases (81%); it was stopped early for: toxicity in 15 (10%), unrelated death in 1 (0.6%), pt preference in 5 (3%) or disease progression in 9 (6%) cases. Dose reductions and delays were required in 61 (39%) and 25 (16%) cases, respectively. Grade 3-5 adverse events were noted in 62 (40%) cases, with 28 (18%) cases of febrile neutropenia (FN); there were no treatment-related deaths. Pts with FN had more bone mets (p = 0.046), but there was no difference in time from start of ADT to initiation of docetaxel, age, baseline performance status, PSA, or visceral involvement. PSA ≤ 0.2 ng/L was achieved in 41 (28%) cases after 6 months of ADT and maintained in 13 (8%) cases after 12 months. 41% of pts had developed CRPC within 1-yr, with a median time to CRPC of 14.3 months. Treatment for CRPC was given in 54 cases, with most pts receiving either abiraterone or enzalutamide (87%) with a PSA decline ≥50% occurring in 47%. Conclusions: Effectiveness of DOC with ADT in a general population of pts with mCSPC was associated with poorer outcomes and high rates of toxicity compared to the phase III studies. Response rates to first-line treatment for mCRPC with abiraterone or enzalutamide appear similar to those previously reported.

Incidence And Mortality

17 Background: Prostate cancer incidence and mortality is higher in African American (AA) as compared with non-AA men. The outcomes of mCSPC have significantly improved through treatment intensification yet, AA representation in those studies was suboptimal. We aimed to report the clinical, treatment outcomes and genomic data of AA men with mCSPC. Methods: Retrospective analysis of consecutive AA men with mCSPC at six Academic Institutions. The primary objective was to report the baseline characteristics and treatment patterns of mCSPC AA patients. The secondary objectives included the germline and somatic data and the clinical outcomes including PSA response, progression-free survival and subsequent treatments. Results: A total of 71 patients, median age 63 years (range, 41-84) with 58% Gleason 8-10, initial PSA of 69.8 ng/mL (0.02-7650), 59% with de-novo and 55% with high-volume (CHAARTED criteria; 20% visceral) disease, were included in this analysis. Twenty-two patients (31%) were treated with androgen deprivation therapy (ADT; 67% prior to year 2017), while 24%, 45% and 3% received docetaxel (median 6 cycles), abiraterone acetate and enzalutamide, respectively. Two patients received triplet therapy with ADT/docetaxel plus abiraterone or enzalutamide. Undetectable PSA was achieved in 35% after a median of 8.9 months (1.8-22.3). Among patients with mCSPC who received radiation therapy to prostate (n = 8), 89% had low volume disease. At time of cut off, thirty-two patients developed CRPC and the estimated median time to CRPC was 2.9 years (95% CI, 1.6-4.2). Subsequent therapies (n = 29) included abiraterone acetate (41%), enzalutamide (24%), bicalutamide (10%), radium-223 (7%), chemotherapy (7%), sipuleucel-T (3%) and others (7%). Five patients (8%) had pathogenic germline alterations (n = 2 BRCA1; n = 1 HOXB13, PALB2 and PMS2). Additionally, the most common somatic alterations among tested patients (n = 27) included CDK12, SPOP, TMPRSS2-ERG fusion, and TP53, all in 11% frequency. Of note, n = 2 BRCA1 and n = 1 high MSI/TMB. Conclusions: In one of the largest reported cohorts to our knowledge, mCSPC AA presented with a high number of de-novo and high-volume disease and might harbor a different germline and somatic genomic profile. The outcomes were comparable to contemporary phase III trials with treatment intensification, yet 31% were treated with ADT. Despite the known limitations associated with retrospective analysis, these data support prior observations where AA might have better initial PSA responses to ADT-based strategies compared with Caucasians, requiring further validation.

687 Background: ENZA, a potent androgen receptor inhibitor, has demonstrated benefit in men with metastatic and nonmetastatic castration-resistant prostate cancer (CRPC). Efficacy of ENZA with ADT in men with mHSPC is unknown. Methods: ARCHES is a multinational, double-blind, phase 3 study (NCT02677896). Patients (pts) with mHSPC were randomized 1:1 to ENZA (160 mg/day) + ADT or PBO + ADT, stratified by disease volume (CHAARTED criteria) and prior docetaxel therapy. Primary endpoint was radiographic progression-free survival (rPFS) assessed centrally or death within 24 weeks of treatment discontinuation. Secondary endpoints included time to prostate-specific antigen (PSA) progression, PSA and radiographic responses and overall survival (OS). Treatment continued until disease progression or unacceptable toxicity. Results: 1150 men were randomized to ENZA (n=574) or PBO (n=576); baseline characteristics were balanced between groups. Overall, 67% had distant metastasis at initial diagnosis; 63% had high volume disease, 18% had prior docetaxel. Median follow-up was 14.4 mo. ENZA + ADT significantly improved rPFS (Table); similar significant improvements in rPFS were reported in prespecified subgroups of disease volume, pattern of spread, region and prior docetaxel (HRs 0.24–0.53). Secondary endpoints improved with ENZA + ADT (Table); OS data are immature. Grade 3–4 adverse events (AEs) were reported in 23.6% of ENZA pts vs 24.7% of PBO pts with no unexpected AEs. Conclusions: ENZA + ADT significantly improved rPFS and other efficacy endpoints vs PBO + ADT in men with mHSPC, with a preliminary safety analysis that appears consistent with the safety profile of ENZA in previous CRPC clinical trials.

Castrate Resistant

Metastatic hormone-sensitive prostate cancer (mHSPC) is an incurable disease, and despite a high response rate to androgen-deprivation therapy (ADT), outcomes have not significantly changed for many decades. Earlier attempts at multitargeted strategies with the addition of cytotoxic chemotherapy to ADT did not affect survival. As more effective therapies are emerging, including cytotoxic therapy for patients with metastatic castrate-resistant prostate cancer (mCRPC), there is increasing interest for testing these drugs earlier in the disease course. The premise is that agents with clinical benefit in advanced mCRPC may have a better effect if used preemptively before the development of significant resistance and to attack earlier de novo androgen resistant/independent clones. The recent results of the phase III clinical trial E3805 investigating ADT with or without docetaxel in mHSPC provide compelling support for this strategy. Docetaxel combined with ADT significantly improved overall survival from 44 to 57.6 months (p = 0.0003), particularly in patients with high-volume disease (from 32.2 to 49.2 months; p = 0.0006). Longer follow-up is needed to assess the effect on patients with low disease burden. Further studies are needed to further maximize the antitumor effect in patients with mHSPC and to investigate the effects of advancing therapy to this disease setting on the efficacy of respective agents in the castration-resistant setting.

5000 Background: Historically, androgen deprivation therapy (ADT) was the standard of care (SOC) for men with mCSPC. Since 2015, combining ADT with either docetaxel, novel hormonal therapies, or radiotherapy to the primary tumor (RXT) (for those with low burden metastases) was shown to improve overall survival (OS) and thus has become the new SOC. It is unknown whether combining these new treatments on top of ADT further increments outcomes. Methods: Men with de novo mCSPC were randomized to SOC, SOC + abiraterone acetate-prednisone (abiraterone), SOC + RXT, or SOC + abiraterone + RXT. SOC was initially ADT alone, then from Oct 2015 onwards the use of docetaxel was authorized as part of SOC (at the investigator’s discretion until 2017, then, following the publication of the LATITUDE and STAMPEDE trials, accrual was restricted to men receiving ADT+docetaxel). The trial has two co-primary endpoints of radiographic progression-free survival (rPFS) and OS with type I error of 0.1% and 4.9%, respectively. The required number of rPFS events to achieve 80% power has been reached for the abiraterone question (not yet for the RXT question). The interaction between abiraterone and RXT was first tested using a Cox model adjusted for stratification factors (performance status, type of castration, metastatic burden, and when applicable, docetaxel). A hierarchical testing was used to test the effect of abiraterone: overall population, then ADT+docetaxel population. Results: From Nov 2013 to Dec 2018, 1173 men were enrolled (SOC was ADT+docetaxel in 710 pts and ADT alone in 463 pts), median age 67y (IQR: 60-72), high volume 57%, low volume 43%. The median follow-up is 3.5y. No interaction was detected between the effect of abiraterone and that of RXT (p = 0.64), allowing to pool abiraterone arms for comparisons. rPFS was significantly improved in the abiraterone arm in the overall population (HR: 0.54 (0.46-0.64), p < 0.0001; medians: 2.2 vs 4.5 years) and in the ADT+docetaxel population: (HR: 0.50 (0.40-0.62), p < 0.0001; medians: 2.0 vs 4.5 years). bPFS (PFS including PSA progression as an event) also significantly favored abiraterone in the overall population (HR: 0.40 (0.35-0.47), p < 0.0001; medians: 1.5 vs 3.8 years) and in the ADT+docetaxel population (HR: 0.38 (0.31-0.47), p < 0.0001; medians: 1.5 vs 3.2 years). OS is maturing. Grade 3-4 adverse events reported in > 5% of pts within the first 6 months in the ADT+docetaxel population included neutropenic fever (4.5% vs 5.4%), liver toxicity (19.7% vs 13%), and hypertension (12.2% vs 8.6%) in the abiraterone and control arms, respectively. Conclusion: Adding abiraterone to ADT + docetaxel significantly improves rPFS in men with de novo metastatic prostate cancer, with about 2.5 years of absolute benefit in medians, and no meaningful additional short-term toxicity. Clinical trial information: NCT01957436.

Background: The phase III MPACT trial demonstrated the superiority of gemcitabine (Gem) combined with Nab-paclitaxel (Nab-P) versus gemcitabine alone in previously untreated patients with metastatic pancreatic ductal adenocarcinoma (PDAC). The purpose of this study was to evaluate the effect of Gem/Nab-P in routine clinical practice. Methods: From January 2015 to December 2018, patients with metastatic PDAC receiving firstline treatment with a combination of gemcitabine and Nab-paclitaxel were included in a multicentre retrospective observational study. Exploratory analyses of efficacy, and prognostic and predictive markers, were performed. Results: The cohort comprised 115 patients (median age 65 [range 50-84] years) with good performance status (ECOG PS 0-1). The median overall survival (OS) was 11 months (95% CI; 9-13) and the median progression-free survival (PFS) was 6 months (95% CI 5-7). Partial response and stable disease were achieved in 44 and 30 patients, respectively, yielding an overall disease control rate (DCR) of 64.3%. Grade 3-4 hematological toxicity frequency was 22.61% for neutropenia, 5.22% for anemia, and 3.48% for thrombocytopenia. Grade 3 asthenia was recorded in 2.61% of patients. No grade 4 non-hematological events were reported. Dose reduction was necessary in 51.3% of the patients. Conclusions: Our results confirm the efficacy and safety of a first-line regimen comprising gemcitabine and Nab-paclitaxel in metastatic PDAC in a real-life population.

Background: Biliary tract cancers (BTC) are uncommon malignancies and are underrepresented in the literature. Methods: We performed a retrospective population-based review of adult patients with biopsy-confirmed BTC in Alberta from 2000 to 2015. Demographic data, risk factors, symptoms, treatment, and staging data were collected and analyzed. Survival analyses were completed. Results: A total of 1604 patients were included in our study, of which 766 (47.8%) were male. The median age at diagnosis was 68 (range 19–99). There were 374 (23.3%) patients with resectable tumors at diagnosis versus 597 (37.2%) with unresectable tumors. Of the patients, 380 (21.5%) received chemotherapy (CT) and 81 (5.0%) underwent radiation therapy. There was a clear trend with worsening stage and performance status associated with shorter median overall survival (OS). Ampulla of Vater tumors had the best median OS (25.69 months), while intrahepatic bile duct cancers had the worst (5.78 months). First-line palliative CT regimens included gemcitabine+cisplatin (OS 14.98 months (mo), n = 212), single agent gemcitabine (OS 12.42 mo, n = 22), capecitabine (OS 8.12 mo, n = 8), and capecitabine+gemcitabine (OS 6.93 mo, n = 13). Patients with advanced or metastatic disease who received first-line gemcitabine+cisplatin had a median OS of 11.8 months (n = 119). Conclusion: BTCs have poor survival. Worse outcomes occur in higher stage and poorer Eastern Cooperative Oncology Group (ECOG) performance status patients across all tumor subtypes. Tumor resectability at diagnosis was associated with better OS. Our study supports the use of gemcitabine+cisplatin as a combination first-line palliative CT, as patients treated in Alberta have a comparable OS to that reported in the ABC-02 phase III study.

De novo cases of metastatic prostate cancer (mCSPC) are associated with poorer prognosis. To assist in clinical decision-making, we aimed to determine the prognostic utility of commonly available laboratory-based markers with overall survival (OS). In a retrospective population-based study, a cohort of 3556 men aged ≥66 years diagnosed with de novo mCSPC between 2014 and 2019 was identified in Ontario (Canada) administrative database. OS was assessed by using the Kaplan–Meier method. Multivariate Cox regression analysis was performed to evaluate the association between laboratory markers and OS adjusting for patient and disease characteristics. Laboratory markers that were assessed include neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), albumin, hemoglobin, serum testosterone and PSA kinetics. Among the 3556 older men with de novo mCSPC, their median age was 77 years (IQR: 71–83). The median survival was 18 months (IQR: 10–31). In multivariate analysis, a statistically significant association with OS was observed with all the markers (NLR, PLR, albumin, hemoglobin, PSA decrease, reaching PSA nadir and a 50% PSA decline), except for testosterone levels. Our findings support the use of markers of systemic inflammation (NLR, PLR and albumin), hemoglobin and PSA metrics as prognostic indicators for OS in de novo mCSPC.

BackgroundTreatment advances have been made in non-small cell lung cancer (NSCLC) with the development and approval of programmed death (PD)-1 and PD-ligand 1 (PD-L1) inhibitors. PD-1 and PD-L1 inhibitors may be used as monotherapies or in combination with other agents and have been shown to improve NSCLC patient outcomes in clinical trials. We conducted a systematic search to compare the efficacy and safety of PD-1/PD-L1 inhibitors in the treatment of NSCLC.MethodsA systematic literature search of PubMed was conducted to identify phase III clinical trials in which the efficacy of PD-1/PD-L1 inhibitors in the treatment of NSCLC was evaluated. PD-1 inhibitors included nivolumab and pembrolizumab; PD-L1 inhibitors included atezolizumab, avelumab, and durvalumab. Patient characteristics and efficacy data were extracted.ResultsSixteen phase III clinical trials were identified (nivolumab=4; pembrolizumab=5; atezolizumab=5; avelumab=1; durvalumab=1). Across the 3 nivolumab monotherapy trials (n=638; median ages: 61–63 years), median progression-free survival (PFS) ranged 2.3–4.2 months; response rates ranged 19%-26%; grade 3/4 adverse events occurred in 7%-18% of patients. Nivolumab in combination with iplimumab (n=583; median age: 64 years) had a median PFS of 5.1 months and response rate of 33%; grade 3/4 adverse events occurred in 33% of patients. Across the 3 pembrolizumab monotherapy trials (n=1,481; median ages: 63–64 years), median PFS ranged 3.9–10.3 months; response rates ranged 18%-45%; grade ≥3 adverse events occurred in 13%-27% of patients. In the 2 pembrolizumab combination therapy trials (n=688; median ages: 65 years), median PFS ranged 6.4–8.8 months; response rates ranged 48%-58%; grade ≥3 adverse events occurred in 67%-70% of patients. In the 4 atezolizumab combination therapy trials (n=1,486; median ages: 63–64 years), median PFS ranged 6.3–8.3 months; response rates ranged 47%-63.5%; grade 3/4 adverse events occurred in 54%-73% of patients. In the 3 monotherapy trials of atezolizumab (n=613; median age: 63 years), avelumab (n=396; median age: 64 years), and durvalumab (n=476; median age: 64 years), the median months of PFS were 2.7, 2.8, and 17.2, respectively; response rates were 14%, 15%, and 30%, respectively; grade ≥3 adverse events occurred in 15%, 10%, and 30.5% of patients, respectively.ConclusionsAlthough treatment responses varied, most of the evaluated PD-1/PD-L1 inhibitors were associated with a clinical benefit for NSCLC trial patients. Generally, treatment efficacy was greater with combination therapies, but adverse events occurred more frequently. Innovations in the targeting/personalization of PD-1/PD-L1 combination therapies will likely lead to improved NSCLC patient outcomes and further research is needed in this regard.

The Impact

359 Background: Statins are HMG-CoA inhibitors that regulate several mechanisms involved in tumor growth, including mitochondrial metabolism, activation of oncogenic signaling pathways, and immune modulation. Population-based studies showed that statin intake may be negatively associated with RCC onset. The impact of statins on response to immunotherapy in mRCC is unknown. Herein we study the association between statin administration and outcomes in patients with mRCC treated with nivolumab in the NIVOREN-GETUG AFU 26 phase II trial (NCT03013335). Methods: Patients with mRCC who failed previous VEGFR inhibitors were included. We assessed nivolumab activity, including objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) according to statin intake at baseline. Toxicity was assessed using CTCAE v4.0. Results: Overall,133 patients were treated with statins at baseline among 702 evaluable for concomitant therapies (19%). Among them, median age was 68 (49-90), 84% were male, 85% had a performance status ≥ 80%, 42% were overweight and 20% obese. Patients treated with statins had mostly good (23%) or intermediate (58%) IMDC risk, 64% had grade 3 or 4 tumors, and nivolumab was given in a third line setting or more in 55%. Median follow-up was 23.9 months (95%CI 23.0-24.5) in the overall cohort. The ORR was 26% in patients treated with statins, PFS 5.0 months (CI95% 3.0 – 5.5), OS 27.9 months (CI95% 19.4-30.3). Outcomes of patients with or without statins did not differ significantly. Similar rates of grade 3-5 TRAE were reported in patients with (20%) or without (18%) statin intake. Conclusions: This is the first study to evaluate statin intake and outcomes with nivolumab in patients with mRCC. Despite numerically higher ORR, statins were not significantly associated with improved outcomes. These data require other analyzes considering other factors such as BMI and other comorbidities. Further studies may help better understand the interplay between immunity and metabolic reprogramming in RCC.

INTRODUCTION Prostate cancer is an excellent target for chemoprevention strategies; given its late age of onset, any delay in carcinogenesis would lead to a reduction in its incidence. This article reviews all the completed and on-going phase III trials in prostate cancer chemoprevention. PATIENTS AND METHODS All phase III trials of prostate cancer chemoprevention were identified within a Medline search using the keywords ‘clinical trial, prostate cancer, chemoprevention’. RESULTS In 2003, the Prostate Cancer Prevention Trial (PCPT) became the first phase III clinical trial of prostate cancer prevention. This landmark study was terminated early due to the 24.8% reduction of prostate cancer prevalence over a 7-year period in those men taking the 5α-reductase inhibitor, finasteride. This article reviews the PCPT and the interpretation of the excess high-grade prostate cancer (HGPC) cases in the finasteride group. The lack of relationship between cumulative dose and the HGPC cases, and the possible sampling error of biopsies due to gland volume reduction in the finasteride group refutes the suggestion that this is a genuine increase in HGPC cases. The other on-going phase III clinical trials of prostate cancer chemoprevention – the REDUCE study using dutasteride, and the SELECT study using vitamin E and selenium – are also reviewed. CONCLUSIONS At present, finasteride remains the only intervention shown in long-term prospective phase III clinical trials to reduce the incidence of prostate cancer. Until we have the results of trials using alternative agents including the on-going REDUCE and SELECT trials, the advice given to men interested in prostate cancer prevention must include discussion of the results of the PCPT. The increased rate of HGPC in the finasteride group continues to generate debate; however, finasteride may still be suitable for prostate cancer prevention, particularly in men with lower urinary tract symptoms.
