  • Apalutamide With or Without Stereotactic Body Radiation Therapy in Treating Participants With Castration-Resistant Prostate Cancer

    Sorry, not yet accepting patients

    This phase II trial studies the how well apalutamide with or without stereotactic body radiation therapy work in treating participants with castration-resistant prostate cancer. Testosterone can cause the growth of prostate cancer cells. Hormone therapy using apalutamide may fight prostate cancer by blocking the use of testosterone by the tumor cells. Stereotactic body radiation therapy is a specialized radiation therapy that sends x-rays directly to the tumor using smaller doses over several days and may cause less damage to normal tissue. It is not yet known whether giving apalutamide with or without stereotactic body radiation therapy works better in treating participants with castration-resistant cancer.

  • CYT107 After Vaccine Treatment (Provenge®) in Patients With Metastatic Castration-Resistant Prostate Cancer

    Sorry, in progress, not accepting new patients

    This randomized phase II trial studies how well glycosylated recombinant human interleukin-7 (CYT107) after vaccine therapy works in treating patients with castration-resistant prostate cancer that has spread to other areas of the body or has not responded to at least one type of treatment. Biological therapies, such as glycosylated recombinant human interleukin-7, may stimulate the immune system in different ways and stop tumor cells from growing. Vaccines made from white blood cells mixed with tumor proteins may help the body build an effective immune response to kill tumor cells. It is not yet known whether glycosylated recombinant human interleukin-7 works better with or without vaccine therapy in treating prostate cancer.

  • Genetic and Molecular Mechanisms in Assessing Response in Patients With Prostate Cancer Receiving Enzalutamide Therapy

    Sorry, in progress, not accepting new patients

    This clinical trial studies genetic and molecular mechanisms in assessing response in patients with prostate cancer receiving enzalutamide therapy. Androgens can cause the growth of prostate cancer cells. Antihormone therapy, such as enzalutamide, may lessen the amount of androgens made by the body. Studying samples of tissue and blood in the laboratory from patients with prostate cancer may help doctors better understand castration-resistant prostate cancer. It may also help doctors make improvements in prostate cancer treatment.

  • Molecular Features and Pathways in Predicting Drug Resistance in Patients With Metastatic Castration-Resistant Prostate Cancer Receiving Enzalutamide

    Sorry, in progress, not accepting new patients

    This research trial studies molecular features and pathways in predicting drug resistance in patients with castration-resistant prostate cancer that has spread to other parts of the body and who are receiving enzalutamide. Studying samples of blood and tissue in the laboratory from patients receiving enzalutamide may help doctors learn more about molecular features and pathways that may cause prostate cancer to be resistant to the drug.
