Plain English Summary

Study Assessing the Efficacy and Safety of Treatment With Alpelisib Plus Fulvestrant in Japanese Men and Postmenopausal Women With Advanced Breast Cancer is a Phase 2 clinical trial sponsored by Novartis Pharmaceuticals studying Advanced Breast Cancer. This trial tests a combination of two drugs, alpelisib and fulvestrant, to see how well they work and how safe they are. It is for men and postmenopausal women in Japan with advanced breast cancer that has a specific genetic mutation (PIK3CA) and has not responded to prior treatment. Participants will receive the study drugs, and their health will be closely monitored through regular visits and tests. Alternative treatments may include other hormone therapies, chemotherapy, or targeted therapies depending on the patient's specific situation and prior treatments. The trial aims to enroll 24 participants.

Official Summary

The purpose of this study is to assess the safety and efficacy of alpelisib plus fulvestrant in men and postmenopausal women with hormone receptor (HR) positive, human epidermal growth factor 2 (HER2)-negative, advanced breast cancer harboring a PIK3CA mutation in Japan, whose disease has progressed on or after aromatase inhibitor (AI) treatment regardless of prior CDK4/6 inhibitor use.

Who Can Participate

Here is what you need to know about eligibility for this trial. Men and postmenopausal women in Japan diagnosed with advanced breast cancer. Patients must have a confirmed PIK3CA gene mutation in their tumor and HER2-negative cancer. The cancer must have progressed after treatment with aromatase inhibitors, and patients should have measurable disease. Individuals with symptomatic visceral disease, certain prior treatments (like PI3K/mTOR/AKT inhibitors or CDK4/6 inhibitors in specific cohorts), or known hypersensitivity to the study drugs cannot participate. This trial is studying Advanced Breast Cancer, so participants generally need a confirmed diagnosis.

What They're Measuring

The primary outcome measures will determine the highest safe dose of the drug combination and how often the cancer shrinks or stops growing in patients who haven't previously received CDK4/6 inhibitor The specific primary outcome measures are: [Part 1] The incidence of Dose Limiting Toxicities (DLTs) of alpelisib in combination with fulvestrant (From Cycle 1 Day 1 to Cycle 2 Day 28 (Cycle = 28 days)); [Part 2] Overall Response Rate (ORR) in CDK4/6 inhibitor naive participants (Up to approximately 36 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 2, which tests whether the treatment actually works against the target condition. Phase 2 trials involve 100-300 patients and continue to monitor safety while evaluating effectiveness. This phase often tests different dosages to find the optimal amount. About 33% of Phase 2 drugs advance to Phase 3. If successful, the treatment will move to large-scale Phase 3 trials needed for FDA approval.

Why This Trial Matters

This trial addresses a need for more effective treatments for advanced breast cancer in Japanese patients with specific genetic mutations, particularly after initial therapies have stopped working. Phase 2 success would typically lead to larger Phase 3 trials needed for regulatory approval. This research targets Advanced Breast Cancer, where improved treatment options are needed.

Investor Insight

This trial focuses on a specific genetic subtype of breast cancer, a growing area of targeted therapy, suggesting potential for a niche market if successful, though competition in advanced breast canc Phase 2 trials have approximately a 15-20% chance of eventually gaining FDA approval.

Is This Trial Right for Me?

Ask your doctor about the specific genetic tests needed to confirm the PIK3CA mutation and HER2 status. Understand the potential side effects of alpelisib and fulvestrant, and how they will be managed during the trial. Be prepared for regular clinic visits for drug administration, blood tests, and imaging scans to monitor your cancer and overall health. The trial is being conducted at 15 sites. Always discuss clinical trial participation with your healthcare provider before making any decisions. This information is for educational purposes only and is not medical advice.
