Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved

Summary

This study tests a new drug, JSB462, combined with standard therapy (abiraterone) in 150 men whose prostate cancer has spread but still responds to hormone treatment. The goal is to see if the combination lowers PSA levels more effectively and delays cancer growth. Participants will receive either the new combo or another standard treatment, and researchers will monitor safety and side effects.

Key Inclusion Criteria: * An Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) ≤2 * Histologically confirmed adenocarcinoma of the prostate. Participants with mixed histology (neuroendocrine) are not eligible * High-volume mHSPC, defined by the presence of ≥1 metastatic visceral non-nodal lesion and/or ≥4 metastatic bone lesions (with at least one lesion outside the vertebral column and/or pelvis) in imaging exams (CT/MRI or bone scan) according to local radiology assessment by the investigator obtained ≤28 days prior to randomization * Participants must have a castrate level of serum/plasma testosterone (\<50 ng/dL or \<1.7 nmol/L). Ongoing ADT (as defined by prior orchiectomy and/or ongoing GnRH analog/antagonist) for ≤90 days is allowed prior to randomization, provided that PSA zero (PSA level \<0.2 ng/ml according to local laboratory as assessed by the investigator) is not achieved prior to randomization. Key Exclusion Criteria: * Prior exposure to a second generation ARPI (such as enzalutamide/darolutamide/apalutamide and/or abiraterone) for the treatment of advanced/metastatic disease is not allowed. Prior exposure to ARPI, to taxane chemotherapy (up to 6 cycles) or to RLT in the context of (neo)adjuvant treatment for localized prostate cancer is allowed, if the last dose of this treatment was administered \>12 months from randomization. Prior use of a first generation ARPI (such as bicalutamide) in the context of ADT initiation with a GnRH analog is allowed, provided the first generation ARPI was administered for ≤14 days and last dose was administered ≥7 days from randomization. * Participants with biochemical recurrence only or those without evidence of metastatic disease by radiological imaging (CT/MRI or bone scan) are not eligible Other inclusion/exclusion criteria may apply.
