Top-line secondary endpoint results from the phase III TRINOVA-1 trial in women with recurrent platinum-resistant ovarian cancer did not demonstrate a statistically significant improvement in overall survival. The study evaluated trebananib plus paclitaxel versus placebo plus paclitaxel.
Median overall survival was 19.3 months in the trebananib arm versus 18.3 months in the control arm. The data will be submitted to a future medical conference and for publication according to Amgen, trebananib’s sponsor.
In the previously reported primary endpoint analysis, the data demonstrated a statistically significant difference in progression-free survival for trebananib. In that analysis, patients treated with trebananib showed a 34 percent reduction in the risk of disease progression or death (HR = 0.66, 95 percent CI, 0.57, 0.77, p<0.001). The median progression-free survival was 7.2 months in the trebananib arm versus 5.4 months in the control arm.
