93 Background: Oligorecurrent pelvic nodal relapse of prostatic cancer is a challenge for regional salvage treatments. We conducted OLIGOPELVIS – GETUG P07, a phase II trial of combined salvage radiotherapy and hormone therapy in oligorecurrent pelvic node relapses of prostate cancer (NCT02274779). Methods: OLIGOPELVIS–GETUG P07 was a prospective multi-center phase II trial investigating high-dose salvage pelvic irradiation with an additional dose to the fluorocholine-based positron-emission-tomography (FCH- PET)-positive pelvic lymph nodes (PLN), combined with six-month androgen blockade (LH-RH agonist or antagonist injections). The prescribed dose was 54 Gy in 1.8 Gy fractions with up to 66 Gy in 2.2 Gy fractions to the pathological PLN. Toxicity (CTCAE v4) and complete response rates (PSA < 0.20 ng/ml) were analyzed. The main objective was to assess biochemical-clinical failure defined by a cluster of events including PSA progression (≥25 % and ≥ 2 ng/ml above the nadir) or clinical evidence of local or metastatic progression or post- treatment initiation of hormonal therapy or prostate cancer-related death. We hypothesized that salvage treatment would achieve a 2-year relapse-free survival of 70 %. Results: Seventy-four patients were recruited in fifteen French radiation oncology departments between August 2014 and July 2016. Seven were excluded before treatment because of violation of the inclusion criteria. The intention-to-treat analysis therefore included sixty-seven patients. Half of them had received prior prostatic/prostate bed irradiation. Median age was 67.7. Grade 2+ two-year urinary and intestinal toxicity were 10% and 2% respectively. At 2 and 3 years, 73.1 and 45.9% of patients achieved a persisting complete response respectively. After a median follow-up of 34 months, the 2-year progression-free survival rate was 77.6%. Median progression-free survival was 40.1 months. Conclusions: Combined pelvic salvage radiotherapy and hormone therapy allowed for prolonged tumor control in oligorecurrent pelvic node relapses of prostate cancer with limited toxicity. Clinical trial information: NCT02274779.

251 Background: This Phase II trial assessed the efficacy of efavirenz, a non-nucleoside reverse transcriptase inhibitor in patients with asymptomatic HRPC [hormone refractory prostate cancer] who progressed, before docetaxel based chemotherapy. Preclinical studies showed that efavirenz, via Line-1 inhibition, could block proliferation and induced re-differentiation of prostate cancer cell line. We then investigated if efavirenz treatment can delay biological and clinical progression. Methods: The primary objective was to assess the efficacy of efavirenz in patients, with no clinical symptom related to disease progression. Each patient received efavirenz 600 mg/day until objective biological progression or study discontinuation. It was possible to increase the dose (up to 1200 mg daily) in case of PSA progression at 3 months. Efficacy was measured in terms of 3-month non-progression. Based on a 2-stage Simon’s design, a total of 16 non-progressions out of 54 eligible patients were required to claim efficacy. Results: 61 patients were enrolled in the study with 53 eligible for the primary endpoint. At baseline, median age was 71 years and median PSA level was 49.6 ng/mL. A total of 15/53 (28%) non-progressions were observed at 3 months. As patients are still being followed, overall survival, PSA progression free survival and symptomatic progression free survival at one year will be presented. Sixty patients were assessable for toxicity. Of these, 9 (15%) experienced at least one grade III/IV toxicity i.e. neuropsychiatric adverse events already reported in efavirenz-treated HIV patients. With regard to pharmacokinetics (PK), preliminary data indicates variability in the 3-month efavirenz concentration. Ongoing preliminary analyses suggest a better response in patients with elevated (>3000ng/ml) plasmatic concentration. Conclusions: Current analyses do not allow to claim efficacy of Efavirenz at the 600 mg dose. The ongoing analysis of the relationship between plasmatic concentration of efavirenz and treatment efficacy could confirm that higher doses of efavirenz may constitute an efficient treatment. A phase I dose escalation study is currently being performed.

BackgroundThe indoleamine 2,3-dioxygenase (IDO) pathway is a key counter-regulatory mechanism that, in cancer, is exploited by tumors to evade antitumor immunity. Indoximod is a small-molecule IDO pathway inhibitor that reverses the immunosuppressive effects of low tryptophan (Trp) and high kynurenine (Kyn) that result from IDO activity. In this study, indoximod was used in combination with a checkpoint inhibitor (CPI) pembrolizumab for the treatment for advanced melanoma.MethodsPatients with advanced melanoma were enrolled in a single-arm phase II clinical trial evaluating the addition of indoximod to standard of care CPI approved for melanoma. Investigators administered their choice of CPI including pembrolizumab (P), nivolumab (N), or ipilimumab (I). Indoximod was administered continuously (1200 mg orally two times per day), with concurrent CPI dosed per US Food and Drug Administration (FDA)-approved label.ResultsBetween July 2014 and July 2017, 131 patients were enrolled. (P) was used more frequently (n=114, 87%) per investigator’s choice. The efficacy evaluable population consisted of 89 patients from the phase II cohort with non-ocular melanoma who received indoximod combined with (P).The objective response rate (ORR) for the evaluable population was 51% with confirmed complete response of 20% and disease control rate of 70%. Median progression-free survival was 12.4 months (95% CI 6.4 to 24.9). The ORR for Programmed Death-Ligand 1 (PD-L1)-positive patients was 70% compared with 46% for PD-L1-negative patients. The combination was well tolerated, and side effects were similar to what was expected from single agent (P).ConclusionIn this study, the combination of indoximod and (P) was well tolerated and showed antitumor efficacy that is worth further evaluation in selected patients with advanced melanoma.

ObjectiveTo investigate the efficacy and safety of hu3S193, a humanized anti-Lewis-Y monoclonal antibody, as a consolidation strategy in patients with platinum-sensitive recurrent epithelial ovarian cancer who achieved a second complete response after salvage platinum-doublet chemotherapy.MethodsThis single-arm phase II study accrued patients with recurrent epithelial ovarian cancer with Lewis-Y expression by immunohistochemistry who had achieved a second complete response after five to eight cycles of platinum-based chemotherapy. Patients received intravenous infusions of hu3S193, 30 mg/m2 every 2 weeks starting no more than 8 weeks after the last dose of chemotherapy and continuing for 12 doses, until disease progression, or unacceptable toxicity. The primary endpoint was progression-free survival of the second remission. Secondary objectives were safety and pharmacokinetics.ResultsTwenty-nine patients were enrolled. Most had a papillary/serous histology tumor (94%), stage III disease at diagnosis (75%), and five (17%) underwent secondary cytoreduction before salvage chemotherapy. Two patients were not eligible for efficacy but were considered for toxicity analysis. Eighteen patients (62%) completed the full consolidation treatment while nine patients progressed on treatment. At the time of analysis, 23 patients (85%) of the eligible population had progressed and seven of these patients (26%) had died. Median progression-free survival of the second remission was 12.1 months (95% CI: 10.6–13.9), with a 1-year progression-free survival of the second remission rate of 50.1%. The trial was terminated early since it was unlikely that the primary objective would be achieved. The most commonly reported treatment-related adverse events were nausea (55%) and vomiting (51%).ConclusionsHu3S193 did not show sufficient clinical activity as consolidation therapy in patients with recurrent epithelial ovarian cancer who achieved a second complete response after platinum-based chemotherapy.Trial registrationNCT01137071.

PURPOSE To evaluate the objective tumor response rate and safety profile of oxaliplatin when administered to patients with previously untreated metastatic colorectal adenocarcinoma. PATIENTS AND METHODS A total of 39 patients were entered onto this phase II trial. One patient was excluded for having had a second cancer, so the study was based on 38 patients. Patients were treated with oxaliplatin 130 mg/m2 as a 2-hour infusion on day 1, every 21 days. Patients were assessed for response every three courses. All clinical and radiologic data were reviewed by an external panel of experts, with their assessment being considered definitive. RESULTS Nine partial responses (PRs) were observed (response rate, 24.3%; 95% confidence interval, 11.8% to 41.2%). The median duration of response was 216+ days. Fifteen patients (40.5%) had stable disease and 13 (35.2%) had progressive disease. The median progression-free survival time for all patients was 126+ days (range, 21 to 447+). The main toxicity was peripheral sensory neuropathy. Grade 3 neurotoxicity (National Cancer Institute common toxicity criteria [NCI-CTC]) was reported in 13%. Hematologic and gastrointestinal toxicities were mild. The incidence of grade 3 neutropenia was 5.2%, while that of grade 3 or 4 thrombopenia was 7.9%. Vomiting (grade 3 or 4) occurred in 7.9% of patients and grade 3 diarrhea in 2.6%. CONCLUSION This phase II study provides clear evidence of the safety and efficacy of oxaliplatin monotherapy at this dose and schedule in patients with previously untreated metastatic colorectal carcinoma.

Purpose Retrospective studies suggest that metastasis-directed therapy (MDT) for oligorecurrent prostate cancer (PCa) improves progression-free survival. We aimed to assess the benefit of MDT in a randomized phase II trial. Patients and Methods In this multicenter, randomized, phase II study, patients with asymptomatic PCa were eligible if they had had a biochemical recurrence after primary PCa treatment with curative intent, three or fewer extracranial metastatic lesions on choline positron emission tomography–computed tomography, and serum testosterone levels > 50 ng/mL. Patients were randomly assigned (1:1) to either surveillance or MDT of all detected lesions (surgery or stereotactic body radiotherapy). Surveillance was performed with prostate-specific antigen (PSA) follow-up every 3 months, with repeated imaging at PSA progression or clinical suspicion for progression. Random assignment was balanced dynamically on the basis of two factors: PSA doubling time (≤ 3 v > 3 months) and nodal versus non-nodal metastases. The primary end point was androgen deprivation therapy (ADT)–free survival. ADT was started at symptomatic progression, progression to more than three metastases, or local progression of known metastases. Results Between August 2012 and August 2015, 62 patients were enrolled. At a median follow-up time of 3 years (interquartile range, 2.3-3.75 years), the median ADT-free survival was 13 months (80% CI, 12 to 17 months) for the surveillance group and 21 months (80% CI, 14 to 29 months) for the MDT group (hazard ratio, 0.60 [80% CI, 0.40 to 0.90]; log-rank P = .11). Quality of life was similar between arms at baseline and remained comparable at 3-month and 1-year follow-up. Six patients developed grade 1 toxicity in the MDT arm. No grade 2 to 5 toxicity was observed. Conclusion ADT-free survival was longer with MDT than with surveillance alone for oligorecurrent PCa, suggesting that MDT should be explored further in phase III trials.

Palb2 Mutation

PURPOSE Five percent to 9% of pancreatic ductal adenocarcinomas (PDACs) develop in patients with a germline BRCA1/2 or PALB2 (g BRCA/PALB2+) mutation. Phase IB data from a trial that used cisplatin, gemcitabine, and veliparib treatment demonstrated a high response rate (RR), disease control rate (DCR), and overall survival (OS) in this population. We designed an open-label, randomized, multicenter, two-arm phase II trial to investigate cisplatin and gemcitabine with or without veliparib in g BRCA/PALB2+ PDAC. PATIENTS AND METHODS Eligible patients had untreated g BRCA/PALB2+ PDAC with measurable stage III to IV disease and Eastern Cooperative Oncology Group performance status of 0 to 1. Treatment for patients in arm A consisted of cisplatin 25 mg/m2 and gemcitabine 600 mg/m2 intravenously on days 3 and 10; treatment for patients in arm B was the same as that for patients in arm A, and arm A also received veliparib 80 mg orally twice per day on days 1 to 12 cycled every 3 weeks. The primary end point was RRs of arm A and arm B evaluated separately using a Simon two-stage design. Secondary end points were progression-free survival, DCR, OS, safety, and correlative analyses. RESULTS Fifty patients were evaluated by modified intention-to-treat analysis. The RR for arm A was 74.1% and 65.2% for arm B ( P = .55); both arms exceeded the prespecified activity threshold. DCR was 100% for arm A and 78.3% for arm B ( P = .02). Median progression-free survival was 10.1 months for arm A (95% CI, 6.7 to 11.5 months) and 9.7 months for arm B (95% CI, 4.2 to 13.6 months; P = .73). Median OS for arm A was 15.5 months (95% CI, 12.2 to 24.3 months) and 16.4 months for arm B (95% CI, 11.7 to 23.4 months; P = .6). Two-year OS rate for the entire cohort was 30.6% (95% CI, 17.8% to 44.4%), and 3-year OS rate was 17.8% (95% CI, 8.1% to 30.7%). Grade 3 to 4 hematologic toxicities for arm A versus arm B were 13 (48%) versus seven (30%) for neutropenia, 15 (55%) versus two (9%) for thrombocytopenia, and 14 (52%) versus eight (35%) for anemia. CONCLUSION Cisplatin and gemcitabine is an effective regimen in advanced g BRCA/PALB2+ PDAC. Concurrent veliparib did not improve RR. These data establish cisplatin and gemcitabine as a standard approach in g BRCA/ PALB2+ PDAC.

Aim: Regorafenib may be active in different cancer types. This Phase II trial included patients with various refractory cancer types treated with regorafenib. Here, we report the results of the pancreatic adenocarcinoma cohort. Methods: The primary end point was progression-free survival (PFS) rate at 8 weeks; further investigation of regorafenib would be warranted with a PFS rate ≥50%. Results: A total of 20 patients were enrolled. The best response was stable disease in four patients (20%). The 8-week PFS rate was 25% with a median PFS of 1.7 months (95% CI: 1.5–2.0). A total of 13 patients (65%) experienced grade 3–4 treatment-related adverse events. Conclusion: The study did not meet its primary end point. Further investigation of regorafenib monotherapy in this setting is not recommended. Clinical Trial Registration: NCT02307500
