The study, published in the Journal of Clinical Oncology found that the 5-year survival with ipilimumab (18.2%) was double that with placebo (8.8%) and roughly double the historical survival rate of patients with stage IV melanoma (approximately 10%).
Among patients with advanced melanoma, twice as many survived to 5 years if they received ipilimumab plus dacarbazine than if they received placebo plus dacarbazine as part of a phase 3 randomized clinical trial, according to a report published online February 23 in the Journal of Clinical Oncology.
The investigators described their analysis as the first examination of long-term survival after a course of ipilimumab therapy, as well as the first analysis of safety outcomes in a small subset of patients who continued to receive ipilimumab as maintenance therapy. They performed this milestone survival analysis “to confirm prior reports of long-term survival in a proportion of patients from nonrandomized phase II studies,” and their findings do in fact confirm those reports, said Dr Michele Maio of University Hospital of Siena (Italy) and her associates.
