Filter by:Background: Prostate cancer does not trigger a strong immune response in the body. Hormone therapy, to reduce levels of testosterone in the body, can be helpful to treat some prostate cancers. However, castration-resistant prostate cancer (CRPC) keeps growing even when the testosterone is reduced to a very low level. Men with metastatic CRPC survive an average of only 3 years. More effective treatments are needed. Objective: To test whether an immunotherapy drug (N-803), alone or in combination with other drugs, can help treat CRPC. Eligibility: Males aged 18 or older with CRPC. Prior treatment with testosterone-lowering therapy is required. Design: Participants will be screened. They will have blood and urine tests. They will have a CT scan of the chest, abdomen, and pelvis. They will continue to receive hormone therapy for prostate cancer. Participants will come to the NIH clinic once a week for the first 4 weeks. Then they will come once every 2 weeks. Visits will last up to 8 hours. The study will continue up to 3 years. All participants will receive N-803 once every 2 weeks. The drug is injected just under the skin with a small needle. Some participants will receive N-803 plus another drug (brachyury vaccine). This drug is also injected under the skin with a small needle. Some participants will receive N-803 plus a different drug (bintrafusp alfa) once every 2 weeks. This drug is given through a tube attached to a needle placed in a vein in the arm. Some participants may receive all 3 drugs. Participants will have imaging scans every 12 weeks.
Depending on the cohort of the study the diagnostic and prognostic accuracy and health economics considerations of [18F]-fluoro-5α-dihydrotestosterone (FDHT)- positron emission tomography (PET) and/or circulating tumor cells in prostate cancer patients are studied.
SMMART-ACT is a feasibility pilot study to determine if testing samples from a participant's cancer using a precision medicine approach can be used to identify specific drugs or drug combinations that can help control their disease. The safety and tolerability of the drug or drug combination is also to be studied. Another purpose is for researchers to study tumor cells to try to learn why some people respond to a certain therapy and others do not, and why some cancer drugs stop working. The study population will include participants with advanced breast, ovarian, prostate, or pancreatic malignancies, or sarcomas.
NUV-422-04 is an open-label Phase 1b/2 dose escalation and expansion study designed to evaluate the safety and efficacy of NUV-422 in combination with enzalutamide. The study population is comprised of adults with mCRPC. Patients will self-administer NUV-422 and 160 mg enzalutamide orally in 28-day cycles. Patients will be treated until disease progression, toxicity, withdrawal of consent, or termination of the study.
This study aims to examine the use of high-intensity interval training (HIIT) and resistance training on docetaxel chemotherapy tolerability and toxicity in metastatic prostate cancer.
This study is being done to establish the mechanisms underlying insulin resistance (reduced insulin action that can lead to high blood sugar and maybe diabetes) in patients undergoing androgen deprivation therapy (ADT) for prostate carcinoma as well as to investigate the role of pioglitazone therapy in reduction/ reversal of that insulin resistance
To perform both PET scans and MRIs in the same setting using a simultaneous PET/MRI scanner.
This phase II trial studies how well gallium-68 PSMA-11 PET/CT or PET/MRI works in finding prostate cancer cells that have come back (recurrent) in patients with prostate cancer. Gallium-68 PSMA-11 is a type of radioactive compound, called a radiotracer, which is injected in the vein and can accumulate in tumor cells to generate a signal detected by PET/CT or PET/MRI imaging. This may help researchers in finding recurrent prostate cancer cells in patients with prostate cancer.
Prostate cancer is the most common malignancy amongst men in United States. Androgen deprivation therapy (ADT) with long acting gonadotropin releasing hormone agonists is routinely used as adjuvant therapy in intermediate and high risk localized or locally advanced prostate cancer. Since ADT induces insulin resistance and diabetes, it is important that cellular and molecular effects of ADT are investigated to define precisely the mechanisms involved in the pathogenesis of insulin resistance. Pioglitazone, a known insulin sensitizer, may provide amelioration of insulin resistance in these patients.
