Parallel phase Ib studies of two schedules of buparlisib (BKM120) plus carboplatin and paclitaxel (q21 days or q28 days) for patients with advanced solid tumors.

ABSTRACT:

Purpose

Phosphatidylinositol-3-kinase I (PI3K) inhibition sensitizes a wide range of cancer cell lines to platinum/taxane-based chemotherapy. This phase I study combines buparlisib, a pan-class 1A PI3K inhibitor, with two schedules of carboplatin and paclitaxel for patients with advanced solid tumors (ClinicalTrials.gov, NCT01297452).

Methods

There were two regimens: Group 1 received carboplatin AUC 5 and paclitaxel 175 mg/m(2), on day 1 of a 21-day cycle with pegfilgrastim support; Group 2 received carboplatin AUC 5 (day 1) and paclitaxel 80 mg/m(2) (days 1, 8, and 15) on a 28-day cycle without growth factor support. In both groups, three dose levels of buparlisib were explored: 50, 80, and 100 mg/day. Primary endpoint was to identify recommended phase II doses of buparlisi
