Spots Global Cancer Trial Database for NeoPHOEBE: Neoadjuvant Trastuzumab + BKM120 in Combination With Weekly Paclitaxel in HER2-positive Primary Breast Cancer

Study Description

Brief Summary: This randomized, parallel cohort, two stage, double-blind, placebo-controlled study evaluated the oral PI3K inhibitor BKM120 in combination with trastuzumab and paclitaxel in HER2-positive, PIK3CA wild-type and PIK3CA mutant primary breast cancer prior to surgery (neo-adjuvant setting).

Detailed Description: NeoPHOEBE evaluated the efficacy (as defined by pCR) of BKM120 (an oral PI3K inhibitor) in combination with trastuzumab and paclitaxel in a randomized, placebo-controlled, neo-adjuvant study in women diagnosed with primary breast cancer \>1.5 cm (by US or MRI) with centrally confirmed HER2 overexpression or amplification, who have not previously undergone treatment for invasive breast cancer. Prior to the initiation of paclitaxel, there was a 6-week "biologic window" with trastuzumab plus BKM120 or placebo only. The study was conducted separately in two cohorts (PIK3CA mutated and PI3K3CA wild-type) using a two-stage approach. Within each cohort patients were randomized into one of the following treatment arms: Arm 1: BKM120 plus trastuzumab for 6 weeks followed by BKM120 and trastuzumab plus weekly paclitaxel for an additional 12 weeks. Arm 2: BKM120 placebo plus trastuzumab for 6 weeks followed by BKM120 placebo plus trastuzumab plus weekly paclitaxel for an additional 12 weeks. After completion of study treatment, patients were to have undergone definitive surgery.
