4025 Background: A combination of S-1 and cisplatin (DDP) has been shown to be effective and safe for the first-line treatment of advanced gastric cancer in Japan. This is the first randomized phase III trial to compare S-1 plus DDP with 5-fluorouracil (5-Fu) plus DDP in Asia. Methods: This is an open-label, multicenter, phase 3, randomized controlled study. Patients with gastric or gastro-oesophageal junction adenocarcinoma were eligible for inclusion. Patients were randomly assigned in a 1:1 ratio to receive S-1 plus DDP (experiment group) or 5-Fu plus DDP (control group) for 6 cycles. In the experiment group, the dose of S-1 was 80 mg/m2/day, po, twice daily on day 1-21 and DDP was 20mg/m2 iv on day 1-4, repeat every 5 weeks. In the control group, 5-Fu was given as 0.8g/m2/d CI 120h ,and the dose of DDP was the same with the experiment group, while repeat every 4 weeks. Allocation was by block randomization stratified by Eastern Cooperative Oncology Group performance status, sites of metastasis and prior gastrectomy. The primary endpoint was time to progression (TTP). Secondary end points included time to failure (TTF), overall survival (OS), and quality of life. Results: Totally 255 patients were enrolled into the study, of whom 236 were included in the analysis (n=120; n=116). Median TTP was 5.51 months (95% CI 4.59-6.26) in those assigned to experiment group compared with 4.62 months (95% CI 4.00-6.33) in the control group (hazard ratio [HR] 1.03; 95%CI 0.76-1.39, p=0.86). In the experiment and control groups, response rates were 22.5% vs 21.5%; P=0.86. Median OS was 10.00 months (95% CI 8.59-14.52) in the experiment group compared with 10.46 months (8.92-13.84) in the control group (HR 1.05; 95%CI 0.71-1.54, p=0.82). The most common adverse events in both groups were anemia (S-1 plus cisplatin, 80.17% vs 5-Fu plus cisplatin, 71.19%), leukopenia (71.90% vs 62.71%), neutropenia (68.60% vs 55.93%), nausea (50.41% vs 60.17%), thrombocytopenia (44.63% vs 26.27%), vomiting (42.98% vs 42.37%) and anorexia (38.02% vs 41.53%). Conclusions: S-1 plus DDP is an effective and tolerable option for patients with advanced gastric or gastro-oesophageal junction adenocarcinoma. Clinical trial information: NCT01198392.

TPS477 Background: In pts with LAPC, more effective systemic therapies may be associated with improved local control, delay of metastasis, and overall survival (OS). The phase III MPACT trial in pts with metastatic PC demonstrated longer OS (median, 8.7 vs 6.6 mos; HR, 0.72; P < 0.001) and an ≈ 3-fold greater shrinkage of primary tumors with nab-P + Gem vs Gem alone (−22.15% vs −7.02%), raising the possibility of improved local PC control with nab-P + Gem. LAPACT will assess the efficacy and safety of nab-P + Gem in LAPC. Methods: LAPACT will enroll treatment-naive pts (planned n ≈ 110) in the United States, Canada, and Europe with Eastern Cooperative Oncology Group performance status ≤ 1, confirmed unresectable LAPC, no distant metastases, and adequate organ function. Pts with mixed-origin tumors, any other malignancy within 5 years, peripheral neuropathy grade > 1, or clinically significant ascites are ineligible. Pts will receive nab-P 125 mg/m2 + Gem 1000 mg/m2 on days 1, 8, and 15 of each 28-day cycle. Pts without progressive disease (PD) or unacceptable toxicity after 6 cycles will receive investigator’s choice of surgery, chemoradiotherapy, or continued nab-P + Gem. If a major response is observed, surgery may occur prior to completing 6 cycles of nab-P + Gem. The primary endpoint is time to treatment failure (TTF; time from first therapy dose to discontinuation due to PD, start of a new non–protocol-defined anti-cancer therapy, or death). The study design allows for 80% power at a 1-sided α of 0.05 to detect a 30% increase over the 5.1-month median TTF observed for nab-P + Gem in the MPACT study. The secondary endpoints are disease control rate (DCR) after 6 cycles, overall response rate, progression-free survival, OS, safety, and quality of life. The exploratory endpoint is correlation of changes in circulating nucleic acids with PD and treatment response. An interim DCR analysis will occur after all pts have completed 6 cycles of nab-P + Gem, discontinued therapy due to PD, died, or started a new non–protocol-defined therapy before completing 6 cycles of therapy. Enrollment is ongoing (first pt enrolled in April 2015). Clinical trial information: NCT02301143.

Purpose This randomized, double-blind, multicenter study aimed to determine the dose of naldemedine, a peripherally-acting μ-opioid receptor antagonist, for future trials by comparing the efficacy and safety of three doses of naldemedine versus placebo in patients with cancer and opioid-induced constipation. Methods Patients ≥ 18 years old with cancer, an Eastern Cooperative Oncology Group performance status ≤ 2, who had been receiving a stable regimen of opioid analgesics for ≥ 2 weeks, had at least one constipation symptom despite laxative use, and no more than five spontaneous bowel movements (SBMs) during the past 14 days, were randomly assigned (1:1:1:1) to oral, once-daily naldemedine 0.1, 0.2, or 0.4 mg, or placebo, for 14 days. The primary end point was change in SBM frequency per week from baseline during the treatment period. Secondary end points included SBM responder rates, change from baseline in the frequency of SBM without straining, and complete SBM. Safety was also assessed. Results Of 227 patients who were randomly assigned, 225 were assessed for efficacy (naldemedine 0.1 mg, n = 55; 0.2 mg, n = 58; 0.4 mg, n = 56; placebo, n = 56) and 226 for safety. Change in SBM frequency (primary end point) was higher with all naldemedine doses versus placebo ( P < .05 for all comparisons), as were SBM responder rates and change in complete SBM frequency. Change in SBM frequency without straining was significantly improved with naldemedine 0.2 and 0.4 (but not 0.1) mg versus placebo (at least P < .05). Treatment-emergent adverse events were more common with naldemedine (0.1 mg: 66.1%; 0.2 mg: 67.2%; 0.4 mg: 78.6%) than placebo (51.8%); the most common treatment-emergent adverse event was diarrhea. Conclusion Fourteen-day treatment with naldemedine significantly improved opioid-induced constipation in patients with cancer and was generally well tolerated. Naldemedine 0.2 mg was selected for phase III studies.

TPS4163 Background: Sorafenib is the accepted first-line systemic therapy for HCC, but no standard option is available for patients with tumor progression following sorafenib. An open-label phase II study suggested that REG, a multikinase inhibitor, had an acceptable safety profile and showed evidence of antitumor activity in patients with progressive HCC (Bolondi et al. Eur J Cancer 2011; 47 [Suppl 1]: abstract 6.576): disease control was achieved in 26/36 patients (72%) and median time to progression (TTP) was 4.3 months; median overall survival (OS) was 13.8 months. On the basis of these promising data, a phase III trial was designed. Methods: This randomized, double-blind, placebo (PBO)-controlled, multinational study (ClinicalTrials.gov identifier NCT01774344) will assess the efficacy and tolerability of REG vs PBO in patients with HCC that has progressed following sorafenib treatment (target n=530). Inclusion criteria include Barcelona Clinic Liver Cancer stage B or C disease, Child–Pugh A liver function, and Eastern Cooperative Oncology Group performance status (ECOG PS) 0 or 1. Patients who discontinued sorafenib ≥8 weeks before study entry or who received other previous systemic therapy for HCC will be excluded. Patients will be randomized in a 2:1 ratio to receive REG 160 mg or matching PBO OD for weeks 1–3 of each 4-week cycle; all patients will also receive best supportive care. Treatment will continue until disease progression, death, intolerable toxicity, or patient/investigator decision to stop. Doses of study drug may be delayed or reduced to manage clinically significant drug-related toxicities. The primary endpoint is OS; secondary endpoints are TTP, progression-free survival, tumor response, and safety. Analysis will be according to randomized group, stratified by geographic region (Asia vs rest of world), ECOG PS (0 vs 1), alfa-fetoprotein level (<400 vs ≥400 ng/ml), extrahepatic disease (yes vs no), and macrovascular invasion (yes vs no). In addition, blood, plasma, and archival tissue will be assessed for pharmacokinetic and biomarker analyses, and health-related quality of life and health utility will be measured. Clinical trial information: NCT01774344.

TPS266 Background: Patients (pts) with MSI-H/dMMR mCRC treated with CT have poorer outcomes than pts with microsatellite stable/MMR proficient mCRC. NIVO (anti–programmed death [PD]-1) and IPI (anti–cytotoxic T lymphocyte antigen-4 [CTLA-4]) are immune checkpoint inhibitors that act synergistically and promote antitumor immune response by complementary mechanisms. NIVO±IPI received accelerated US FDA approval for MSI-H/dMMR mCRC that progressed after fluoropyrimidine, oxaliplatin, and irinotecan treatment based on the phase 2, non-randomized, multicohort CheckMate 142 study. Indirect comparisons suggest that NIVO (3 mg/kg) + low-dose IPI (1 mg/kg) provides improved clinical benefit vs NIVO (investigator-assessed [INV] objective response rate [ORR] 55% vs 31%; 12-month [mo] INV progression-free survival [PFS] rate 71% vs 50%; 12-mo overall survival [OS] rate 85% vs 73%) with a favorable benefit-risk profile for previously treated MSI-H/dMMR mCRC (Overman et al. JCO 2018). NIVO+low-dose IPI also demonstrated robust and durable clinical benefit in first-line MSI-H/dMMR mCRC (INV ORR 64%; 12-mo INV PFS rate 77%; 12-mo OS rate 84%; Lenz et al. ASCO 2019, #3521). To date, no prospective phase 3 studies have reported results for anti–PD-1, anti–PD-1 + anti–CTLA-4, or CT in MSI-H/dMMR mCRC; these treatments will be evaluated in the international, multicenter, open-label, randomized, phase 3 CheckMate 8HW (NCT04008030) study. Methods: Approximately 494 pts aged ≥18 years with histologically confirmed recurrent or mCRC, irrespective of prior treatment with CT and/or targeted agents, not amenable to surgery, and with known tumor MSI-H or dMMR status, and Eastern Cooperative Oncology Group performance status ≤1 will be randomized to receive NIVO, NIVO+IPI, or investigator’s choice CT (pts in the CT arm can receive NIVO+IPI upon progression). The primary endpoint is PFS, assessed by blinded independent central review (BICR). Secondary endpoints include PFS by INV, ORR and disease control rate by BICR and INV, OS, time to and duration of response. Exploratory endpoints include safety. Clinical trial information: NCT04008030.

Purpose A randomized, placebo-controlled study based on preclinical and clinical data that supports the potential role of vascular endothelial growth factor in prostate cancer was performed to evaluate the addition of bevacizumab to standard docetaxel and prednisone therapy in patients with metastatic castration-resistant prostate cancer (mCRPC). Patients and Methods Patients with chemotherapy-naive progressive mCRPC with Eastern Cooperative Oncology Group performance status ≤ 2 and adequate bone marrow, hepatic, and renal function were randomly assigned to receive docetaxel 75 mg/m2 intravenously (IV) over 1 hour for 21 days plus prednisone 5 mg orally twice per day (DP) with either bevacizumab 15 mg/kg IV every 3 weeks (DP + B) or placebo. The primary end point was overall survival (OS), and secondary end points were progression-free survival (PFS), 50% decline in prostate-specific antigen, objective response (OR), and toxicity. Results In total, 1,050 patients were randomly assigned. The median OS for patients given DP + B was 22.6 months compared with 21.5 months for patients treated with DP (hazard ratio, 0.91; 95% CI, 0.78 to 1.05; stratified log-rank P = .181). The median PFS time was superior in the DP + B arm (9.9 v 7.5 months, stratified log-rank P < .001) as was the proportion of patients with OR (49.4% v 35.5%; P = .0013). Grade 3 or greater treatment-related toxicity was more common with DP + B (75.4% v 56.2%; P ≤ .001), as was the number of treatment-related deaths (4.0% v 1.2%; P = .005). Conclusion Despite an improvement in PFS and OR, the addition of bevacizumab to docetaxel and prednisone did not improve OS in men with mCRPC and was associated with greater toxicity.

PURPOSE Acalabrutinib, a highly selective, potent, Bruton tyrosine kinase inhibitor, was evaluated in this global, multicenter, randomized, open-label, phase III study in patients with relapsed/refractory (R/R) chronic lymphocytic leukemia (CLL). METHODS Eligible patients, aged ≥ 18 years with R/R CLL, were randomly assigned 1:1 centrally and stratified by del(17p) status, Eastern Cooperative Oncology Group performance status score, and number of prior lines of therapy. Patients received acalabrutinib monotherapy or investigator’s choice (idelalisib plus rituximab [I-R] or bendamustine plus rituximab [B-R]). The primary end point was progression-free survival (PFS) assessed by an independent review committee (IRC) in the intent-to-treat population. Key secondary end points included IRC-assessed overall response rate, overall survival, and safety. RESULTS From February 21, 2017, to January 17, 2018, a total of 398 patients were assessed for eligibility; 310 patients were randomly assigned to acalabrutinib monotherapy (n = 155) or investigator’s choice (n = 155; I-R, n = 119; B-R, n = 36). Patients had received a median of two prior therapies (range, 1-10). After a median follow-up of 16.1 months (range, 0.03-22.4 months), median PFS was significantly longer with acalabrutinib monotherapy (PFS not reached) compared with investigator’s choice (16.5 months [95% CI, 14.0 to 17.1 months]; hazard ratio, 0.31 [95% CI, 0.20 to 0.49]; P < .0001). Estimated 12-month PFS was 88% (95% CI, 81% to 92%) for acalabrutinib and 68% (95% CI, 59% to 75%) for investigator’s choice. Serious adverse events occurred in 29% of patients (n = 44 of 154) treated with acalabrutinib monotherapy, 56% (n = 66 of 118) with I-R, and 26% (n = 9 of 35) with B-R. Deaths occurred in 10% (n = 15 of 154), 11% (n = 13 of 118), and 14% (n = 5 of 35) of patients receiving acalabrutinib monotherapy, I-R, and B-R, respectively. CONCLUSION Acalabrutinib significantly improved PFS compared with I-R or B-R and has an acceptable safety profile in patients with R/R CLL.

Purpose S-1 plus cisplatin is considered highly active in Japanese gastric cancer patients. We conducted a phase II multi-institutional trial, in the West, in patients with untreated advanced gastric or gastroesophageal junction adenocarcinoma to evaluate activity and safety of this combination. Methods Patients received cisplatin intravenously at 75 mg/m2 on day 1 and S-1 orally at 25 mg/m2/dose bid (50 mg/m2/d) on days 1 to 21, repeated every 28 days. Patients with histologic proof of gastric or gastroesophageal junction adenocarcinoma with a Karnofsky performance status (KPS) of ≥ 70% and near-normal organ function were eligible. All patients provided a written informed consent. To observe a 45% confirmed overall response rate (ORR), 41 assessable patients were needed. Results All 47 patients were assessed for safety and survival, and 41 patients were assessed for ORR. The median age was 56 years and median KPS was 80%. The median number of chemotherapy cycles was four. The confirmed ORR was 51% (95% CI, 35% to 67%) and it was 49% by an independent review. At the 6-month interval, 71% of patients were alive, with a median survival time of 10.9 months. Frequent grade 3 or 4 toxicities included fatigue (26%), neutropenia (26%), vomiting (17%), diarrhea (15%), and nausea (15%); however, stomatitis (2%) and febrile neutropenia (2%) were uncommon. There was one (2%) treatment-related death. Conclusion S-1 plus cisplatin is active against gastric cancer and has a favorable toxicity profile. A global phase III study of S-1 plus cisplatin versus fluorouracil plus cisplatin currently is accruing patients.

Purpose A phase III study comparing eribulin with dacarbazine in patients with advanced liposarcoma (LPS) or leiomyosarcoma showed a significant improvement in overall survival (OS) for the eribulin arm, with a manageable toxicity profile. We now report the histology-specific subgroup analysis of the efficacy and safety of eribulin compared with dacarbazine in patients with LPS, an independently randomized stratified subgroup of this phase III trial. Methods Patients ≥ 18 years with advanced or metastatic dedifferentiated, myxoid/round cell, or pleomorphic LPS incurable by surgery or radiotherapy were included. Patients with Eastern Cooperative Oncology Group performance status ≤ 2 and two or more prior systemic treatment regimens, including one with anthracycline, were randomly assigned 1:1 to receive eribulin mesylate (1.4 mg/m2 intravenously on days 1 and 8) or dacarbazine (850, 1,000, or 1,200 mg/m2 intravenously on day 1) every 21 days. OS, progression-free survival (PFS), and safety were analyzed. Results In the LPS subgroup, OS was significantly improved: 15.6 versus 8.4 months (hazard ratio, 0.51; 95% CI, 0.35 to 0.75; P < .001) with eribulin versus dacarbazine, respectively. Longer OS with eribulin was observed in all LPS histologic subtypes and in all geographic regions evaluated. PFS was also improved with eribulin versus dacarbazine (2.9 v 1.7 months, respectively; hazard ratio, 0.52; 95% CI, 0.35 to 0.78; P = .0015). Adverse events were similar between arms. Conclusion In patients with previously treated LPS, eribulin was associated with significantly superior OS and PFS compared with dacarbazine. Eribulin represents an important treatment option for patients with LPS, a sarcoma subtype for which limited effective systemic treatments are available. Further studies are justified to explore the role of eribulin in earlier lines of therapy as well as in combination with other agents.

Corticosteroid Dose

BackgroundNo treatment demonstrated to improve survival in patients with recurrent glioblastoma (rGB) in a randomized trial. Combining axitinib with the programmed cell death ligand 1 blocking monoclonal antibody avelumab may result in synergistic activity against rGB.MethodsAdult patients with rGB following prior surgery, radiation therapy and temozolomide chemotherapy were stratified according to their baseline use of corticosteroids. Patients with a daily dose of ≤8 mg of methylprednisolone (or equivalent) initiated treatment with axitinib (5 mg oral two times per day) plus avelumab (10 mg/kg intravenous every 2 weeks) (Cohort-1). Patients with a higher baseline corticosteroid dose initiated axitinib monotherapy; avelumab was added after 6 weeks of therapy if the corticosteroid dose could be tapered to ≤8 mg of methylprednisolone (Cohort-2). Progression-free survival at 6 months (6-m-PFS%), per immunotherapy response assessment for neuro-oncology criteria, served as the primary endpoint.ResultsBetween June 2017 and August 2018, 54 patients (27 per cohort) were enrolled and initiated study treatment (median age: 55 years; 63% male; 91% Eastern Cooperative Oncology Group Performance Status 0–1). Seventeen (63%) patients treated in Cohort-2 received at least one dose of avelumab. The 6-m-PFS% was 22.2% (95% CI 6.5% to 37.9%) and 18.5% (95% CI 3.8% to 33.2%) in Cohort-1 and Cohort-2, respectively; median overall survival was 26.6 weeks (95% CI 20.8 to 32.4) in Cohort-1 and 18.0 weeks (95% CI 12.5 to 23.5) in Cohort-2. The best objective response rate was 33.3% and 22.2% in Cohort-1 and Cohort-2, respectively, with a median duration of response of 17.9 and 19.0 weeks. The most frequent treatment-related adverse events were dysphonia (67%), lymphopenia (50%), arterial hypertension and diarrhea (both 48%). There were no grade 5 adverse events.ConclusionThe combination of avelumab plus axitinib has an acceptable toxicity profile but did not meet the prespecified threshold for activity justifying further investigation of this treatment in an unselected population of patients with rGB.

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.
