Recurrent Ovarian Cancer

July 1, 2013

Amgen reported results from a phase III trial of trebananib plus paclitaxel v. placebo plus paclitaxel for the treatment of recurrent ovarian cancer. This global, multicenter, randomized, double-blind, placebo-controlled study enrolled 900 women with recurrent partially platinum-sensitive or -resistant (platinum-free interval of 12 months or less) epithelial ovarian, primary peritoneal or fallopian tube cancer. Patients were randomized 1:1 to receive either 15mg/kg of intravenous trebananib weekly plus 80mg/m of intravenous paclitaxel weekly (three weeks on, one week off) or weekly intravenous placebo plus 80mg/m of intravenous paclitaxel weekly (three weeks on, one week off). The trial met its primary endpoint of progression-free survival (PFS). A statistically significant difference was observed in PFS with a 34% reduction in the risk of disease progression or death (HR = 0.66, 95% CI, 0.57, 0.77, p<0.001). The median PFS was 7.2 months in the trebananib arm v. 5.4 months in the control arm.

Pfizer released positive preliminary results from a phase II trial of sunitinib for the treatment of non-small cell lung cancer (NSCLC). The trial was designed to compare sunitinib (37.5 mg/day) in combination with erlotinib (150 mg/day) in previously treated subjects with advanced NSCLC. The primary endpoint was safety and tolerability. Secondary endpoints included anti-tumor activity. The combination treatment was generally safe and well tolerated, with all adverse events mild to moderate in nature. Two subjects had partial response; one which was maintained for >3 months and one which was currently ongoing. In addition, stable disease up to or more than 16 weeks was observed in two subjects. The randomized portion of this trial is currently underway.
