Study Assessing the Efficacy and Safety of Alpelisib + Nab-paclitaxel in Subjects With Advanced TNBC Who Carry Either a PIK3CA Mutation or Have PTEN Loss Without PIK3CA Mutation

Acronym

Scientific title

A Phase III, Multicenter, Randomized, Double-blind, Placebo-controlled Study to Assess the Efficacy and Safety of Alpelisib (BYL719) in Combination With Nab-paclitaxel in Patients With Advanced Triple Negative Breast Cancer With Either Phosphoinositide-3-kinase Catalytic Subunit Alpha (PIK3CA) Mutation or Phosphatase and Tensin Homolog Protein (PTEN) Loss Without PIK3CA Mutation

Acronym

Brief summary of the study: English

The purpose of this study is to determine whether treatment with alpelisib in combination with nab-paclitaxel is safe and effective in subjects with advanced triple negative breast cancer (aTNBC) who carry either a PIK3CA mutation (Study Part A) or have PTEN loss without PIK3CA mutation (Study Parts B1 and B2)

Brief summary of the study: Arabic

دراسة متعددة المراكز، عشوائيّة التوزيع، مزدوجة التعمية، مرتكزة على المقارنة بدواء وهمي في المرحلة الثالثة، لتقييم فعاليّة وسلامة ألبيليسيب (BYL719) بالاشتراك مع ناب-باكليتاكسيل (nab-paclitaxel) لدى المرضى المصابين بسرطان الثدي الثلاثي السلبي المتقدم إمّا مع طفرة في جين PIK3CA أو مع فقدان البروتين مماثل الفوسفاتاز والتنسين PTEN بدون طفرة في جين PIK3CA

Health conditions/problem studied: Specify

Triple Negative Breast Neoplasms

Interventions: Specify

Drug: alpelisib 300 mg orally once per day (QD) Other Name: BYL719 Drug: placebo 300 mg orally once per day (QD) Other Name: alpelisib matching placebo Drug: nab-paclitaxel 100 mg/m² as IV infusion on Days 1, 8 and 15 of a 28-day cycle Other Name: abraxane

Key inclusion and exclusion criteria: Inclusion criteria

Subject has histologically confirmed diagnosis of advanced (loco-regionally recurrent and not amenable to curative therapy, or metastatic (stage IV)) TNBC Subject has either a measurable disease per RECIST 1.1 criteria or, if no measurable disease is present, then at least one predominantly lytic bone lesion or mixed lytic-blastic bone lesion with identifiable soft tissue component (that can be evaluated by CT/MRI) must be present Part B1: patients must have measurable disease Subject has adequate tumor tissue to identify the PIK3CA mutation status (either carrying a mutation or without a mutation) and the PTEN loss status; both of which will determine whether the subject can be allocated to Part A - PIK3CA mutation regardless of PTEN status; or to Part B - PTEN loss without a PIK3CA mutation Subject has an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 Subject has received no more than one line of therapy for metastatic disease. Subject has adequate bone marrow and organ function
