Abiraterone

The purpose of this study is to compare the efficacy and safety of BMS-986365 versus the investigator's choice of therapy in participants with Metastatic Castration-resistant Prostate Cancer.

The purpose of this substudy is to assess the efficacy and safety of ifinatamab deruxtecan (I-DXd), given alone or with other treatments in participants with metastatic castration-resistant prostate cancer (mCRPC). The goals of this study are to learn about: * The safety of the study treatment and if people tolerate it. * A safe dose level of I-DXd that can be used with other treatments. * Participant levels of prostate specific antigen (PSA) during treatment.

The purpose of this study is to evaluate the efficacy and safety of 177Lu-TLX591 in patients with metastatic castration-resistant prostate cancer who have progressed following treatment with Androgen Receptor Pathway Inhibitor Treatment

This phase II trial studies the effects of stereotactic body radiation therapy (SBRT) and the timing of treatment with androgen receptor pathway inhibitor (ARPI) plus androgen deprivation therapy (ADT) in treating patients with hormone sensitive prostate cancer that has spread from where it first started to other places in the body (metastatic), and that has come back after a period of improvement (recurrent). It also studies the effects of salvage radiation therapy (sXRT) on prostate cancer and to see if radiation to the pelvis helps prevent prostate cancer from spreading elsewhere. SBRT is a type of external radiation therapy that uses special equipment to position a patient and precisely deliver radiation to tumors in the body (except the brain). The total dose of radiation is divided into smaller doses given over several days. This type of radiation therapy helps spare normal tissue. Androgen can cause the growth of prostate cells. ADT lowers the amount of androgen made by the body. This may help stop the growth of tumor cells that need androgen to grow. Androgen receptor pathway inhibitors work by blocking the effects of androgen to stop the growth and spread of tumor cells. sXRT is a targeted radiation treatment for the prostate, typically given when cancer possibly returns after surgery or radiation. Its goal is to destroy any tumor cells in the area. Giving SBRT alone with watchful waiting may be as effective in treating prostate cancer as giving SBRT together with ARPI and ADT and sXRT may be effective in treating prostate cancer and preventing it from spreading elsewhere.

The purpose of this study is to assess the safety, tolerability, pharmacokinetics/pharmacodynamics, preliminary anti-tumor activity, and recommended dose of INR731 as a single agent and in combination with standard-of-care androgen receptor pathway inhibitors (ARPIs) in adult patients with metastatic prostate cancer.

This study is being done to answer the following question: can the chance of prostate cancer growing or spreading be lowered by adding a drug to the usual combination of drugs? This study would like to find out if this approach is better or worse than the usual approach for prostate cancer. The usual approach for patients who are not in a study is hormone treatment with Androgen Deprivation Therapy (ADT) and Androgen-Receptor Pathway Inhibitor (ARPI).

This phase II trial studies how well prostate specific membrane antigen (PSMA) or fluciclovine positron emission tomography (PET)/computed tomography (CT) site-directed therapy works for treating patients with prostate cancer. PSMA or fluciclovine PET/CT may detect prostate cancer early and may help to show whether patients benefit from site directed treatment to PET detected abnormalities.

This study will evaluate the efficacy and safety of the combination of inavolisib plus enzalutamide compared with physician's choice of alternative androgen receptor pathway inhibitor (ARPi) or docetaxel in biomarker-selected participants with metastatic castrate-resistant prostate cancer (mCRPC) who have received one prior second-generation ARPi.

The intention of the study is to demonstrate superiority of AZD2265 relative to standard of care treatments by assessment of radiographic progression-free survival (rPFS) and overall survival (OS) in participants with mCRPC.

The purpose of this phase Ib/II study is to (a) in Phase Ib evaluate the safety, tolerability, and pharmacokinetics (PK) of AMO959 when given in combination with lutetium (177Lu) vipivotide tetraxetan (also known as \[177Lu\]Lu-PSMA-617 or 177Lu-PSMA-617 and hereafter referred to as AAA617) with an androgen receptor pathway inhibitor (ARPI) in participants with metastatic castration resistant prostate cancer (mCRPC) who have failed one prior ARPI and with or without prior taxane exposure, and (b) in Phase II evaluate the preliminary efficacy of AMO959 in combination with AAA617 and ARPI in participants with mCRPC who have failed one prior ARPI, but who have not yet been exposed to taxane treatment.

The main objective of the trial is to evaluate the safety and tolerability of xaluritamig in combination with darolutamide or abiraterone.
