Plain English Summary

Study of Alpelisib (BYL719) in Combination With Trastuzumab and Pertuzumab as Maintenance Therapy in Patients With HER2-positive Advanced Breast Cancer With a PIK3CA Mutation is a Phase 3 clinical trial sponsored by Novartis Pharmaceuticals studying Advanced HER2+Breast Cancer. Tests alpelisib with trastuzumab and pertuzumab for HER2-positive advanced breast cancer with PIK3CA mutation. For patients with advanced HER2+ breast cancer who have completed induction therapy. Participation involves taking alpelisib or placebo daily and regular check-ups. Alternative treatments include standard chemotherapy and targeted therapies. The trial aims to enroll 19 participants.

Official Summary

The purpose of this two part multicenter, randomized, double-blind, placebo-controlled, Phase III study is to evaluate the efficacy and safety of alpelisib compared to alpelisib matching-placebo in combination with trastuzumab and pertuzumab as maintenance treatment of patients with HER2-positive advanced breast cancer whose tumor harbors a PIK3CA mutation following induction therapy with a taxane in combination with trastuzumab and pertuzumab. Part 1 is the open-label, safety run-in part of the study, designed to confirm the recommended phase 3 dose (RP3D) dose of alpelisib in combination with trastuzumab and pertuzumab. Following Part 1, Part 2 will be initiated, which is the randomized, Phase III part of the study.

Who Can Participate

Here is what you need to know about eligibility for this trial. Eligible if HER2-positive breast cancer, advanced stage, completed induction therapy, and has PIK3CA mutation. Not eligible if has inflammatory breast cancer, disease progression, diabetes, heart disease, or certain lung conditions. This trial is studying Advanced HER2+Breast Cancer, so participants generally need a confirmed diagnosis.

What They're Measuring

Measures include progression-free survival and overall response rate, beneficial for patients by potentially extending treatment duration. The specific primary outcome measures are: Part 1: Incidence of dose limiting toxicities (DLTs) for each dose level (6 weeks); Part 2: Progression Free Survival (PFS) (Up to approximately 38 months). These endpoints are how researchers determine whether the treatment is effective and will form the basis of any future regulatory submissions.

About This Phase

This trial is in Phase 3, the final and most rigorous stage before seeking FDA approval. Phase 3 trials involve 300-3,000+ patients across multiple sites and compare the new treatment directly against the current standard of care. These pivotal trials generate the evidence needed for regulatory review. About 58% of Phase 3 drugs receive FDA approval. Successful Phase 3 results typically lead to a New Drug Application submission.

Why This Trial Matters

This trial aims to fill a treatment gap for HER2+ breast cancer patients with PIK3CA mutations, offering a new combination therapy. As a Phase 3 trial, positive results could directly lead to FDA approval, making this treatment available to the broader patient population. This research targets Advanced HER2+Breast Cancer, where improved treatment options are needed.

Investor Insight

Market size is large for HER2+ breast cancer, with strong competition but a promising landscape for innovative treatments. Phase 3 trials have approximately a 50-60% chance of gaining FDA approval if they reach this stage.

Exclusion Criteria:

* Participant with inflammatory breast cancer at screening.
* Participant with evidence of disease progression during the pre-study induction therapy and prior to first dose of alpelisib (or alpelisib/alpelisib matching-placebo for Part 2)
