S-1 as monotherapy or in combination with leucovorin as second-line treatment in gemcitabine-refractory advanced pancreatic cancer: a randomized, open-label, multicenter, phase II study.

ABSTRACT: In this study, we compared the efficacy and safety of the oral fluoropyrimidine S-1 as monotherapy or in combination with leucovorin as the second-line treatment for patients with metastatic pancreatic cancer whose disease had progressed on gemcitabine treatment.The study was a randomized, open-label, controlled study. Patients randomly received S-1 or S-1 in combination with leucovorin (SL arm) in 21-day cycles. The primary endpoint was the 6-month survival rate.A total of 92 patients were randomized to S-1 (n = 47) and SL (n = 45). No statistically significant differences were observed between the two arms with regard to 6-month survival rates (40% vs. 49%), median overall survival (5.5 vs. 6.3 months), median progression-free survival (1.9 vs. 3.0 months), and overall response rate (4.7% vs. 8.3%). The rate of major grade 3-4 adverse events of digestive toxicity was significantly higher in the SL arm than in the S-1 arm.Compared with S-1, SL did not improve the survival of patients with metastatic pancreatic cancer who had failed to benefit from prior gemcitabine treatment, but SL had a higher adverse event rate.

Project description:BackgroundNivolumab has been approved in China as second-line treatment for advanced non-small-cell lung cancer (NSCLC) via weight-based infusion, based on the CheckMate 078 study. We investigated the safety and efficacy of 240 mg flat-dose nivolumab in patients with advanced NSCLC, including those with hepatitis B virus (HBV) and epidermal growth factor receptor (EGFR) mutation/ALK receptor tyrosine kinase (ALK) translocation due to high prevalence in China.MethodsCheckMate 870 was a single-arm, open-label, phase IIIb trial in Asian (primarily Chinese) patients with previously treated advanced NSCLC. Patients received flat-dose nivolumab 240 mg every 2 weeks (Q2W) for up to 2 years. The primary endpoint was the incidence and severity of treatment-related select adverse events (TRsAEs) in non-HBV patients; secondary and exploratory endpoints included severity of high-grade TRsAEs in HBV-infected patients, and safety, efficacy and patient-reported outcomes (PROs) in the whole population.ResultsOut of 404 patients enrolled, 400 received treatment. Median (standard deviation) age was 60.5 (8.68) years and the majority were male (78.5%). At a median follow-up of 37.6 months, no Grade 5 TRsAEs were reported, and the frequency of Grade 3-4 TRsAEs was low (0.0-5.9%) in non-HBV and HBV NSCLC patients. Median overall survival (OS) and progression-free survival (PFS) in all treated patients were 14.7 (12.3-18.1) and 3.6 (2.3-3.8) months, respectively. Median OS was 14.2 (12.3-18.1) and 22.3 (10.0-NA) months for non-HBV and HBV-infected patients, 19.3 (11.2-31.7) and 13.7 (11.5-18.1) months for EGFR-positive and wild-type subgroups, and 19.3 (12.9-23.5) and 13.3 (10.9-17.7) months for those with programmed death-ligand 1 (PD-L1) expression ⩾1% and <1%, respectively. No notable changes from baseline were observed in PROs throughout the study.ConclusionNivolumab 240 mg infusion Q2W was well tolerated, efficacious, and maintained health status and quality of life in Asian patients with previously treated advanced NSCLC regardless of HBV, EGFR, or PD-L1 status.

Project description:BackgroundNatural killer/T-cell lymphoma (NKTCL) is a disease with limited treatment options and poor outcomes. Daratumumab monotherapy demonstrated clinical activity in a single-patient case report. We present data from the primary analysis of a phase 2 study of daratumumab monotherapy in relapsed or refractory (R/R) NKTCL.MethodsThis phase 2 study with Simon's two-stage design evaluated daratumumab in patients with histologically confirmed extranodal NKTCL, nasal type, per WHO classification that was refractory to or relapsed after ≥ 1 line of chemotherapy, who were not candidates for other treatment modalities. All patients received daratumumab 16 mg/kg intravenously once weekly for Cycles 1 and 2, every other week for Cycles 3 through 6, and every 4 weeks thereafter until progression or unacceptable toxicity; all cycles were 28 days. The primary end point was objective response rate (ORR) based on blinded independent central review per Revised Criteria for Response Assessment of Hodgkin and non-Hodgkin Lymphoma (Lugano classification).ResultsIn total, 32 Asian patients received daratumumab. The ORR was 25.0% (95% confidence interval [CI] 11.5-43.4); all 8 responders had a partial response; and the median duration of response was 55.0 days (95% CI 29-339). At 10.2 months of median follow-up, median progression-free survival (PFS) was 53.0 days (95% CI 43-106); the 4-month PFS rate was 13.0%. Median overall survival (OS) was 141.0 days (95% CI 94-438); the 6-month OS rate was 42.9%. Nineteen (59.4%) patients had grade 3/4 treatment-emergent adverse events (TEAEs); the most common was thrombocytopenia (25.0%; n = 8). TEAEs leading to death occurred in 4 patients (death, respiratory failure, septic shock, and pneumonia); all were unrelated to daratumumab.ConclusionsIn patients with R/R NKTCL, daratumumab monotherapy was well tolerated with no new safety concerns and achieved an ORR of 25.0%. However, no patients achieved complete response, and duration of response was short. Trial registration ClinicalTrials.gov, NCT02927925. Registered 7 October 2016.
