Help Us Improve Diagnosis of Prostate Cancer!

Prostate biopsies play a crucial role in deciding whether men with elevated Prostate Specific Antigen (PSA) have cancer and whether treatment is needed. Not all forms of prostate cancer require treatment, only those that are worrisome and thus clinically significant. Standard prostate biopsy can miss the most aggressive areas...

The purpose of this study is to determine how patients with metastatic castration-resistant prostate cancer, and evidence of a homologous recombination gene deficiency, respond to treatment with rucaparib.

A Study of Rucaparib Versus Physician's Choice of Therapy in Patients With Metastatic Castration-resistant Prostate Cancer and Homologous Recombination Gene Deficiency

The purpose of this study is to determine how patients with metastatic castration-resistant prostate cancer, and evidence of a homologous recombination gene deficiency, respond to treatment with rucaparib versus treatment with physician's choice of abiraterone acetate, enzalutamide, or docetaxel.

An Efficacy and Safety Study of Niraparib in Men With Metastatic Castration-Resistant Prostate Cancer and DNA-Repair Anomalies

This is a multicenter and open-label (participants and researchers are aware of the treatment that participants are receiving) study that consists of 4 phases; a Prescreening Phase for biomarker evaluation only, a Screening Phase, a Treatment Phase (Cycle 1 Day 1 and will continue until the study drug is discontinued),...

The purpose of this study is to assess the efficacy and safety of the combination of pembrolizumab (MK-3475) and docetaxel in the treatment of men with metastatic castration-resistant prostate cancer (mCRPC) who have not received chemotherapy for mCRPC but have progressed on or are intolerant to Next Generation Hormonal Agent...

Standard Systemic Therapy With or Without Definitive Treatment in Treating Participants With Metastatic Prostate Cancer

PRIMARY OBJECTIVES: I. To compare overall survival in metastatic prostate cancer patients who are randomized to standard systemic therapy (SST) plus definitive treatment of the primary tumor versus standard systemic therapy alone. SECONDARY OBJECTIVES: I. To compare overall survival in metastatic prostate cancer patients who received SST plus surgical excision...
