Castration Levels of TestosteroneCastration-Resistant Prostate Carcinoma3 moreThis randomized phase II trial studies how well abiraterone acetate and antiandrogen therapy, with or without cabazitaxel and prednisone, work in treating patients with castration-resistant prostate cancer previously treated with docetaxel that has spread to other parts of the body. Androgens can cause the growth of prostate cancer cells. Hormone therapy using abiraterone acetate and antiandrogen therapy may fight prostate cancer by lowering and/or blocking the use of androgens by the tumor cells. Drugs used in chemotherapy, such as cabazitaxel and prednisone, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving abiraterone acetate and antiandrogen therapy with or without cabazitaxel and prednisone may help kill more tumor cells.

Docetaxel, Carboplatin, and Rucaparib Camsylate in Treating Patients With Metastatic Castration...
ATM Gene MutationBRCA1 Gene Mutation8 moreThis phase II trial studies how well docetaxel with carboplatin followed by rucaparib camsylate works in treating patients with metastatic castration resistant prostate cancer (spread outside of prostate and resistant to testosterone suppression) with homologous recombination DNA repair deficiency. Chemotherapy drugs, such as docetaxel and carboplatin, work to stop the growth of cancer cells, by stopping them from dividing or spreading. Rucaparib camsylate may stop the growth of tumor cells with defects in the ability to repair mistakes in DNA by forcing additional errors so that the cancer cells cannot overcome the number of errors and will then die. Giving induction docetaxel and carboplatin followed by maintenance rucaparib camsylate may work better in treating patients with castration resistant prostate cancer.

Ultra-hypofractionated Radiation in Prostate Cancer
Early Stage Prostate CancerThe primary objective of this study is to demonstrate that ultra-hypofractionation of prostate cancer does not increase urinary toxicity as defined by the EPIC-26 GU domain patient reported outcome.

A Study of Niraparib Combination Therapies for the Treatment of Metastatic Castration-Resistant...
Prostatic NeoplasmsCastration-ResistantThe purpose of this study is to: a) establish the recommended phase 2 dose (RP2D) and to evaluate the antitumor activity and safety of niraparib combination therapies (Combinations 1 and 2) and b) to determine the relative bioavailability of niraparib and abiraterone acetate (AA) in combination (Combination 3) in participants with metastatic castration-resistant prostate cancer (mCRPC).

RAD 1801: Pilot Study of Intra-Urethral Radiotransponder Beacon Guided Focal Prostate Stereotactic...
Prostate CancerThis study offers focal therapy for prostate cancer by using an intra-urethral radiotransponder temporarily placed during radiotherapy. The study aims to improve the risk-benefit ratio of therapy for early prostate cancer and potentially lessen symptom burden over time.

Hypofractionated Boost vs Conventionally Fractionated Boost for Localized High Risk Prostate Cancer...
Prostate CancerRandomized trial comparing 2 external beam radiotherapy fractionation schemes in patients with localized high risk prostate cancer. Primary endpoint is acute toxicity.

A Study of Niraparib in Combination With Abiraterone Acetate and Prednisone Versus Abiraterone Acetate...
Metastatic Castration-sensitive Prostate CancerThe purpose of the study is to determine if the combination of niraparib with Abiraterone Acetate (AA) plus prednisone compared with AA plus prednisone in participants with deleterious germline or somatic Homologous Recombination Repair (HRR) gene-mutated Metastatic Castration-Sensitive Prostate Cancer (mCSPC) provides superior efficacy in improving radiographic progression-free survival (rPFS).

Testing the Addition of Darolutamide to Hormonal Therapy (Androgen Deprivation Therapy [ADT]) After...
Prostate CarcinomaThis phase III trial compares the effect of adding darolutamide to ADT versus ADT alone after surgery for the treatment of high-risk prostate cancer. ADT reduces testosterone levels in the blood. Testosterone is a hormone made mainly in the testes and is needed to develop and maintain male sex characteristics, such as facial hair, deep voice, and muscle growth. It also plays role in prostate cancer development. Darolutamide blocks the actions of the androgens (e.g. testosterone) in the tumor cells and in the body. Giving darolutamide with ADT may work better in eliminating or reducing the size of the cancer and/or prevent it from returning compared to ADT alone in patients with prostate cancer.

A Study of Apalutamide (Adjuvant Treatment) and Androgen Deprivation Therapy (ADT) in Participants...
Prostatic NeoplasmsMain Study: The purpose of main study is to assess if the combination of apalutamide and androgen deprivation therapy (ADT) in participants with high-risk localized prostate cancer improves the biochemical recurrence (BCR) free rate. Sub-study: The purpose of the sub-study is to assess if the co administration of apalutamide and relugolix is able to maintain castrate levels of testosterone.

Androgen Deprivation Therapy Combined With Docetaxel for High Risk Prostate Cancer
Neoadjuvant Therapy \ High Risk Prostate Cancer \ DocetaxelThis randomized, controlled, single center clinical trial aims to evaluate the efficacy and safety of Androgen Deprivation Therapy Combined with Docetaxel for High Risk Prostate Cancer with a six-month treatment cycle.
