Study of Safety and Efficacy of Dapagliflozin + Metformin XR Versus Metformin XR in Participants With HR+, HER2-, Advanced Breast Cancer While on Treatment With Alpelisib and Fulvestrant — EPIK-B4

Breast Cancer Clinical Trial

Official title:
EPIK-B4: A Phase II, Multicenter, Randomized, Open-label, Active-controlled Study to Assess the Safety and Efficacy of Dapagliflozin + Metformin XR Versus Metformin XR During Treatment With Alpelisib (BYL719) in Combination With Fulvestrant in Participants With HR+, HER2-, Advanced Breast Cancer With a PIK3CA Mutation Following Progression on/After Endocrine-based Therapy

Status Terminated

Clinical Trial Summary

This study was designed to assess the safety and efficacy of the combination of dapagliflozin plus metformin extended release (XR) compared with metformin XR during treatment with alpelisib plus fulvestrant in participants with Hormone Receptor (HR)-positive, Human Epidermal growth factor Receptor-2 (HER2)-negative advanced breast cancer with a Phosphoinositide-3-Kinase Catalytic subunit Alpha (PIK3CA) mutation following progression on or after endocrine-based therapy.

Clinical Trial Description

This was a multicenter, randomized, open-label, active-controlled trial, stratified by diabetic status at baseline (i.e., normal vs prediabetic/diabetic based on fasting plasma glucose (FPG) and/or Hemoglobin A1c (HbA1c) laboratory values). The study included only participants with at least one baseline risk factor for the development of severe hyperglycemia which were diabetes (FPG ≥ 126 milligram (mg)/deciliter (dL) or ≥ 7.0 millimole (mmol)/liter (L) and/or HbA1c ≥ 6.5%), prediabetes (FPG ≥ 100 mg/dL to < 126 mg/dL or 5.6 to < 7.0 mmol/L and/or HbA1c 5.7 to < 6.5%), obesity (body mass index [BMI] ≥ 30) and age (≥ 75 years). The planned duration of treatment with alpelisib and fulvestrant was 12 cycles (28 days in each cycle) or until disease progression, unacceptable toxicity, or discontinuation from study treatment for any other reason, whichever came first. Approximately 66 participants in each treatment arm were planned to be randomized to receive the combination of alpelisib and fulvestrant with either dapagliflozin plus metformin extended release (XR) or metformin XR alone. As a result of the early termination of the study due to emerging data demonstrating the impact of prophylactic metformin and slow recruitment, only 2 participants were enrolled in the study. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
