A Phase II, Randomized, Open-label, Multi-center Study of JSB462 (Luxdegalutamide) in Combination With Abiraterone in Adult Male Patients With Metastatic Hormone-sensitive Prostate Cancer (mHSPC)


Sponsor

Novartis Pharmaceuticals

Enrollment

150 participants

Start Date

Jul 7, 2025

Study Type

INTERVENTIONAL

Summary

This Phase II study aims to evaluate efficacy and safety of the combination of JSB462 (also known as luxdegalutamide) at 100 mg and 300 mg once a day (QD) doses + abiraterone compared with an androgen receptor pathway inhibitor (ARPI, abiraterone or enzalutamide) in participants with metastatic Hormone Sensitive Prostate Cancer (mHSPC) and to select the recommended dose of the combination for phase III. Towards that end, the totality of the efficacy, safety, tolerability and PK data from participants randomized in the study will be evaluated

Sex: MALEMin Age: 18 Years

Plain Language Summary

Simplified for easier understanding

This study is testing a combination of two drugs — JSB462 (luxdegalutamide) and abiraterone — in men with prostate cancer that has spread widely to the bones or other organs and is still responding to hormone therapy. **You may be eligible if...** - You are male with prostate cancer that has spread (metastatic) - Your cancer is still sensitive to hormone therapy (testosterone is in the castration range) - You have 4 or more bone metastases, or at least 1 spread to other organs - You have been on hormone therapy for no more than 90 days before enrolment **You may NOT be eligible if...** - You have previously received newer hormone-blocking drugs like enzalutamide, apalutamide, darolutamide, or abiraterone for advanced disease - You only have a rising PSA level with no visible cancer on scans Talk to your doctor to see if this trial is right for you.
