Abstract

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).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
