This study is trying a new treatment (Xaluritamig) for men whose prostate cancer returned after the first treatment, but has not spread. The objective is to determine if Xaluritamig is safe and works well without causing negative side effects seen in other treatments. Participants will get Xaluritamig through a vein in their arm over six times with doctors observing for side effects and to see how the cancer reacts.

The purpose of this study is to determine the safety and efficacy of the Vanquish System treatment in men who have intermediate risk prostate cancer. In this study, the Vanquish System will be used to destroy cancerous tissue in the prostate. After treatment, participants will undergo tests that will assess presence of prostate cancer.

ADT is a systemic therapy called hormone therapy which reduces the androgen hormone (testosterone) levels to prevent prostate cancer cells from growing. This study is being done to learn more about a new drug called darolutamide given in combination with ADT for prostate cancer.

The purpose of this study is to test the safety and effectiveness of Copper Cu 64 PSMA I&T in detecting lesions during a PET scan. This study is open to men with newly diagnosed prostate cancer who plan to have a prostatectomy and lymph node removal. Copper Cu 64 PSMA I&T is an investigational PET imaging agent, given to you via IV injection, similar to the way other imaging agents are used in many other types of scans. Cu 64 specifically targets the prostate specific membrane antigen (PSMA) that is found on the surface of metastatic prostate cancer cells. Increased image contrast may make it easier for the doctor to see smaller lesions compared to other imaging agents.

The goal of this current study is to test whether men with prostate cancer that is getting worse after treatment with hormone therapy and abiraterone respond better to alternating treatment with testosterone and enzalutamide vs. enzalutamide alone. We are testing to see which is better at stopping tumor growth that can be seen on a bone scan or CT scan and the effect of each regimen on lowering Prostate Specific Antigen (PSA values). Participants will be in the study for 6 to 24 months.

This trial is testing MK-5684 in men with metastatic castration-resistant prostate cancer (mCRPC) previously treated with next-generation Hormonal Agent (NHA) and Taxane-based chemotherapy. This trial will compare MK-5684 to abiraterone acetate and enzalutamide. Abiraterone acetate and enzalutamide are standard treatments for mCRPC. The purpose of this trial is to test the safety of the trial drug, MK-5684, see how well the drug works, and see how the body handles the drug. We also want to see if participants who get MK-5684 live longer compared to those who get abiraterone acetate or enzalutamide.

To compare the effects of treatment with enzalutamide (ENZ) versus darolutamide (DARO) on the cognitive function of men with non-metastatic and metastatic castration-resistant prostate cancer (mCRPC) by comparing the change in the maximally changed cognitive domain from baseline in patients in each study arm by 24 weeks.

The purpose of this research is to compare any good and bad effects of using radium-223 along with docetaxel chemotherapy (at a lower dose) treatment versus using docetaxel alone (at the usual dose). The addition of radium-223 to docetaxel could be a better cancer treatment than just docetaxel alone, but it could also cause additional side effects. This study will allow the researchers to know whether this different approach is better, the same, or worse than the usual approach.
