Safety and Antitumor Activity of Anti–PD-1 Antibody, Nivolumab, in Patients With Platinum-Resistant Ovarian Cancerстатья из журнала
Аннотация: Purpose Programmed death-1 (PD-1), a coinhibitory immune signal receptor expressed in T cells, binds to PD-1 ligand and regulates antitumor immunity. Nivolumab is an anti–PD-1 antibody that blocks PD-1 signaling. We assessed the safety and antitumor activity of nivolumab in patients with platinum-resistant ovarian cancer. Patients and Methods Twenty patients with platinum-resistant ovarian cancer were treated with an intravenous infusion of nivolumab every 2 weeks at a dose of 1 or 3 mg/kg (constituting two 10-patient cohorts) from October 21, 2011. This phase II trial defined the primary end point as the best overall response. Patients received up to six cycles (four doses per cycle) of nivolumab treatment or received doses until disease progression occurred. Twenty nivolumab-treated patients were evaluated at the end of the trial on December 7, 2014. Results Grade 3 or 4 treatment-related adverse events occurred in eight (40%) of 20 patients. Two patients had severe adverse events. In the 20 patients in whom responses could be evaluated, the best overall response was 15%, which included two patients who had a durable complete response (in the 3-mg/kg cohort). The disease control rate in all 20 patients was 45%. The median progression-free survival time was 3.5 months (95% CI, 1.7 to 3.9 months), and the median overall survival time was 20.0 months (95% CI, 7.0 months to not reached) at study termination. Conclusion This study, to our knowledge, is the first to explore the effects of nivolumab against ovarian cancer. The encouraging safety and clinical efficacy of nivolumab in patients with platinum-resistant ovarian cancer indicate the merit of additional large-scale investigations (UMIN Clinical Trials Registry UMIN000005714).
