A Study of JSB462 (Luxdegalutamide) Plus Lutetium (177Lu) Vipivotide Tetraxetan in Patients With Metastatic Castration Resistant Prostate Cancer (mCRPC)

This Phase II study aims to evaluate the efficacy and safety of the combination of JSB462 (also known as luxdegalutamide) at 100 mg and 300 mg QD doses + lutetium (177Lu) vipivotide tetraxetan (hereafter referred as AAA617) compared with AAA617 (control) in participants with metastatic Castration Resistant Prostate Cancer (mCRPC) with prior exposure to at least 1 Androgen Receptor Pathway Inhibitor (ARPI) and 0-2 taxane regimens and to select the recommended dose of the combination for phase III. Towards that end, the totality of the efficacy, safety, tolerability and pharmacokinetic (PK) data from participants randomized in the study will be evaluated.

Treatment With Darolutamide +/- Radiation Therapy for Patients With a Castration Resistant Cancer and Metastases Detected by Functional Imaging

In earlier stages of prostate cancer, male sexual hormones (androgens) stimulate the growth of cancer cells. Castration-resistant prostate cancer (CRPC) means that the prostate cancer continued to grow despite patients are taking hormone therapy to control the disease. One of the standard treatments for these patients is so-called 'new generation' hormonal therapy. These hormone therapies include apalutamide, enzalutamide, or darolutamide. They work by blocking androgen receptors that play an important role in the growth of prostate cancer. In the case of oligometastatic CRPC, the cancer has gone beyond the prostate and has spread to other organs in the body (metastases), but these metastases remain limited in number. An early detection of the oligometastatic CRPC and appropriate treatment may prolong survival in these patients. The treatment proposed as part of this research is a combination of oral darolutamide, approved in Europe to treat patients with CRPC who do not have metastasis visible on CT-scan or bone scintigraphy (but visible with positron emission tomography-scan (PET-Scan), a more precise imaging technique) with stereotactic body radiotherapy (SBRT), a new radiotherapy technique guided by very high precision medical imaging. This method makes it possible to better target cancer cells while preserving neighboring healthy organs. The principal objective of this trial is to evaluate the efficacy of the combination of SBRT with darolutamide, compared to darolutamide.
