This study is for subjects that have been diagnosed with prostate cancer, and their doctor has recommended external beam radiation therapy. The purpose of the study is to evaluate the side effects of a shorter course of radiation called stereotactic ablative body radiotherapy (SABR). The expected duration of the study is up to 28 months including one to four months prior to radiation therapy for treatment preparation, two weeks during radiation therapy, and 24 months after radiation therapy.

This study is for men with prostate cancer that has come back after surgery. This study is being done to see if PET/CT scans help provide more tailored treatment recommendations and outcomes for men who have prostate cancer after radical prostatectomy (RP) and will adding focal, metastasis directed radiation treatment (e.g.., stereotactic radiation) and/or additional systemic therapy (e.g., apalutamide) to standard of care treatment help to delay progression of prostate cancer in men who have already had an RP and now have recurrence?

This study is for subjects that have been diagnosed with prostate cancer that can be removed by surgery. The purpose of this study is to determine whether a group of drugs called statins can help to reduce the risk of prostate cancer returning after surgery. The drug used in this study is a particular type of statin called simvastatin. Simvastatin is approved by the Food and Drug Administration (FDA) to help lower cholesterol (fatty deposits in your blood) and decrease the risk of heart disease. Its use in this research study is considered investigational, and not FDA approved for the subject's cancer. Subjects can expect to be in the active participation portion of this study for about 3 months. Afterwards, the study team may contact them or their medical providers every 6 months to follow their cancer care and collect information on their current health status.

This study is for men with unfavorable intermediate risk prostate cancer, a low gene risk score and plan to receive radiation therapy with hormone therapy. The purpose of the study is to answer to find out if radiation therapy alone is as effective at controlling the cancer compared to the usual combination of radiation and hormone therapy. The study is also going to determine if adding another new hormone therapy drug to the usual combination of radiation and hormone therapy increase the length of time without the prostate cancer spreading compared to the usual treatment.

This study is for patients with prostate cancer. The purpose of this study is to find out of adding Sunphenon® 90D to normal treatment will lower the chance of the cancer growing.

This study is for subjects that have been diagnosed with advanced solid cancer tumors or relapsed prostate cancer. The investigational drugs in this study are hydroxychloroquine, nelfinavir, metformin, dasatinib and sirolimus. The purpose of this study is to determine the safety and effectiveness of up to 5 study drugs used together for the treatment of cancer. Subjects can expect to be in this study for about 2.5 years.

This study is for men who have high-risk prostate cancer who plan to be treated with a combination of radiation and hormonal therapy. A tumor genomic analysis (Decipher score) will be used to divide the subjects into two groups. Those with a low genomic risk score will be randomized to either standard treatment with radiation and 24 months of hormonal therapy or to radiation with a shorter, 12 month, course of hormone therapy. Those with a higher genomic risk score or who have lymph node involvement will be randomized to standard treatment with radiation and 24 months of standard hormonal therapy or radiation with 24 months of intensified hormonal therapy.

This study is for men who have prostate cancer. The purpose of this study is to compare the effects, good and/or bad, of adding either prostate removal surgery or radiation therapy of the prostate to standard systemic therapy (SST), which is used to treat prostate cancer.
