Overall response rate of 26.3% in patients with cervical cancer regardless of PD-L1, HPV status and number of prior systemic therapies
Median duration of response has not been reached after 6 months of follow-up
PRINCETON, N.J.--(BUSINESS WIRE)--Bristol-Myers Squibb Company (NYSE:BMY) today announced the first disclosure of data from a cohort of the Phase 1/2 CheckMate -358 study evaluating Opdivo (nivolumab) for the treatment of patients with advanced cervical, vaginal and vulvar cancers, all associated with infection by the human papillomavirus (HPV). The cohort included 24 patients, 19 of which were cervical cancer patients. The preliminary efficacy measures from the Phase 1/2 CheckMate -358 study (N=24) in patients with advanced cervical, vaginal and vulvar cancers, included an objective response rate (ORR), the primary endpoint, of 20.8% (95% CI: 7.1 to 42.2), with a 70.8% disease control rate of women experiencing complete or partial response or stable disease. The median progression-free survival (PFS) was 5.5 months (95% CI: 3.5 to not reached) and the median overall survival (OS) was not yet reached. Responses were seen only in cervical cancer patients. Of the 19 women with cervical cancer, five had complete and partial responses, with an ORR of 26.3% (95% CI: 9.1 to 51.2). Median duration of response has not been reached after 6 months of follow-up. Opdivo showed a safety profile consistent with previous results seen with Opdivo monotherapy in other tumor types. Grade 3/4 treatment-related adverse events (AEs) occurred in 12.5% of patients. These data will be presented today in an oral session at 4:12 to 4:24 PM CDT at the American Society of Clinical Oncology (ASCO) Annual Meeting 2017.
“These CheckMate -358 results demonstrate the value of studying the potential of an Immuno-Oncology agent to address the significant challenge of treating patients with advanced cervical, vaginal and vulvar cancers,” said lead investigator Antoine Hollebecque, M.D., senior medical physician, Gustave Roussy Cancer Institute in Villejuif, France. “As a clinical investigator, I am encouraged by these findings in the women with advanced cervical cancer, and look forward to the anticipated data from the planned longer term analyses.”
