1.Primary Outcome
Title Phase I: Recommended Phase II Dose (RP2D) of BYL-719 (Alpelisib) + Nab-paclitaxel to be Used in Combination to Treat Advanced HER2-negative Breast Cancer
Hide Description Phase I was a 3+3 dose escalation design (three dose levels of alpelisib: 250mg, 300mg, and 350mg orally once daily, continuous dosing) with dose-limiting toxicities (DLT) assessed during the first treatment cycle. If two or more of the six patients experienced a dose-limiting toxicity, dosing escalation would cease and maximum tolerated dose (MTD) would be reached. RP2D was the next lower dose at which <1/6 subjects experienced a DLT.

Title Correlation of PIK3CA Mutation With Clinical Benefit Rate
Hide Description Comparison of clinical benefit rate between participants with and without PIK3CA mutation in tumor tissue and/or circulating tumor DNA. Clinical benefit rate includes complete response (CR), partial response (PR), plus stable disease (SD) ≥16 weeks, as evaluated per RECIST version 1.1. Tumor DNA was isolated from archived formalin-fixed, paraffin-embedded tumor tissue (primary or metastatic site) and subjected to next-generation sequencing for assessment of PIK3CA mutation using ONCOReveal Multi-Cancer Panel (Pillar Biosciences). Circulating tumor DNA was isolated from pre-treatment plasma samples and subjected to next-generation sequencing for assessment of PIK3CA mutation using FoundationOne CDx testing or ONCOReveal Multi-Cancer Panel.
Time Frame 24 months
Hide Outcome Measure Data
Hide Analysis Population Description
Among 42 participants evaluable for response, 17 had PIK3CA mutation in tumor tissue and/or circulating tumor DNA, while 25 did not. Clinical benefit rate was assessed among participants with PIK3CA mutation separately from participants without PIK3CA mutation for the purpose of correlating clinical benefit rate with PIK3CA mutation status. Per protocol the analysis is reported for all participants evaluable for response, thus participants from all dose levels are combined for this analysis.
