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 patients that have already received standard treatments for their cancer and their cancer has gotten worse or returned after their last treatment. The purpose of this study is to learn about the effects of the study drug XL092 when given alone, in combination with atezolizumab, and in combination with avelumab by testing its safety, the ability of your body to accept the drug(s), to measure the drug(s) and/or its break-down products levels in your blood, and how your body reacts to the drug(s). This research study will be the first time XL092 alone or in combination with atezolizumab will be given to people. The study drugs in this research have not been approved by the United States Food and Drug Administration (FDA). There are two parts in this study, a Dose Escalation part and a Cohort Expansion part. The first part of the study was the Dose Escalation phase, when different participants were given different doses of the study drug until the safest, most effective dose was found; this part of the study has been completed. The study is now enrolling to the Cohort Expansion part of this study, where the dose that has been determined to be safe will be given to more participants with different types of cancer. The Dose Escalation part of this study has stopped and the safe dose has been found. This study is now enrolling to the Cohort Expansion part of this study, where the safe dose of the study drug found in the Dose Escalation part will be given to more participants with different types of cancer. Participants will either be assigned to the treatment group that will receive XL092 alone or the treatment group that XL092 in combination with atezolizumab. Which treatment group they are assigned depends on the type of cancer they have. TXL092 is in tablet form taken by mouth. Avelumab will be given as an intravenous (IV) infusion once every 2 weeks at the study site. Atezolizumab will be given as an intravenous (IV) infusion once every 3 weeks at the study site. Total study duration is expected to be about 6 months but participants could be in the study for up to 2 years.

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 men with prostate cancer with high risk disease. The purpose of this study is to see if the addition of a new drug, darolutamide, to standard Androgen Deprivation Therapy (ADT) (a hormonal therapy that is a usual approach to treatment) after surgery cure more men with prostate cancer than using Androgen Deprivation Therapy alone.

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 is a phase II study that will look at the safety and effectiveness of the investigational drug opaganib in participants with metastatic prostate cancer. The study drug, opaganib has been studied in a clinical trial to find a safe dose level. The results of this clinical trial and other lab studies have indicated that opaganib may be effective at slowing tumor growth. Patients will be eligible to participate in this study if they have prostate cancer that has progressed (gotten worse) on their current therapy of either abiraterone or enzalutamide. Participants will received either 250mg or 500mg of opaganib by mouth twice a day. Patients will continue on study drug until the development of progressive disease, intolerable toxicity, withdrawal of patient consent or other event as outlined in patient discontinuation.

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.
