Patients, whose median age was 58, were enrolled from October 2011 to June 2013. As of March 2014, median progression-free survival was 9.2 months for olaparib and 16.7 months for the combination therapy, which is a significant advantage. The overall rate of toxicity was higher for patients on the combination therapy. Fatigue, diarrhea, and hypertension were the most common toxic effects, all of which were manageable.
