NCT ID: NCT05807126 Withdrawn - Clinical trials for Anatomic Stage IV Breast Cancer AJCC v8

Testing the Addition of Immunotherapy With Hu5F9-G4 (Magrolimab) to the Usual PARP Inhibitor, Olaparib for Treatment of Metastatic or Recurrent Breast or Castrate-Resistant Prostate Cancer With BRCA Mutations

Start date: March 5, 2024
Phase: Phase 1
Study type: Interventional

This phase I/Ib trial studies the side effects and best dose of Hu5F9-G4 (magrolimab) when given in combination with olaparib for the treatment of patients with breast or castrate-resistant prostate cancer that have spread from where they first started (primary site) to other places in the body (metastatic) or have come back after a period of improvement (recurrent) and have mutations in the BRCA1/2 genes. Magrolimab is a monoclonal antibody with potential anticancer activity and the cability to stimulate the immune system and may interfere with the ability of tumor cells to grow and spread. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Olaparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep tumor cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. Combination therapy with magrolimab and olaparib may be safe and effective in treating BRCA-mutated metastatic or recurrent breast or castrate-resistant prostate cancer.

NCT ID: NCT05445882 Withdrawn - Clinical trials for Castration Resistant Prostate Cancer

N-803 Alone or in Combination With BN-Brachyury Vaccine or Bintrafusp Alfa (M7824) for Participants With Castration Resistant Prostate Cancer

Start date: April 1, 2024
Phase: Phase 2
Study type: Interventional

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.

NCT ID: NCT05191017 Withdrawn - Prostate Cancer Clinical Trials

Study of NUV-422 in Combination With Enzalutamide in Patients With mCRPC

Start date: September 2022
Phase: Phase 1/Phase 2
Study type: Interventional

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.

NCT ID: NCT04781374 Withdrawn - Prostate Cancer Clinical Trials

Neratinib in Patients With Metastatic Castration-Resistant Prostate Cancer

Start date: May 21, 2021
Phase: Phase 2
Study type: Interventional

This research study is examining whether Neratinib has any activity in participants with prostate cancer that has spread and is no longer responding to hormonal treatment. - The names of the study drug involved in this study is neratinib.

NCT ID: NCT03709550 Withdrawn - Clinical trials for Castration-Resistant Prostate Carcinoma

Enzalutamide and Decitabine in Treating Patients With Metastatic Castration Resistant Prostate Cancer

Start date: April 15, 2021
Phase: Phase 1/Phase 2
Study type: Interventional

This phase I/II trial studies the side effects and best dose of decitabine and how well it works when given together with enzalutamide in treating patients with castration resistant prostate cancer that has spread to other places in the body. Androgen can cause the growth of prostate cancer cells. Drugs, such as enzalutamide, may lessen the amount of androgen made by the body. Decitabine may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving decitabine and enzalutamide may work better in treating participants with castration resistant prostate cancer.

NCT ID: NCT03596710 Withdrawn - Clinical trials for Stage IV Prostate Cancer

Image-Guided Biopsies in Identifying Mechanisms of Resistance in Participants With Metastatic Castration Resistant Prostate Cancer Undergoing Radioligand Therapy

Start date: June 14, 2018
Phase: N/A
Study type: Interventional

This trial studies image-guided biopsies work in identifying mechanisms of resistance in participants with castration resistant prostate cancer that has spread to other places in the body and who are undergoing radioligand therapy (RLT). Tissue sample collected from a biopsy may help determine why response to RLT varies among patients, and this may help researchers to find better treatments for advanced prostate cancer.

NCT ID: NCT02054793 Withdrawn - Prostate Cancer Clinical Trials

Phase Ib/II Study Evaluating Orteronel (Without Prednisone) Combined With Itraconazole In Men With Castration-Resistant Prostate Cancer (CRPC)

Start date: June 2014
Phase: Phase 1/Phase 2
Study type: Interventional

This research is being done to test the safety and anti-cancer activity of the combination of an investigational drug called orteronel, with a drug called itraconazole in the treatment of castration-resistant prostate cancer. Orteronel is an investigational drug known as a 17,20-lyase enzyme inhibitor, meaning that it blocks the formation of male sex hormones. Itraconazole is approved by the Food and Drug Administration (FDA) for the treatment of various fungal infections such as fingernail/toenail infections and other more serious fungal infections. While it has shown evidence of activity against prostate cancer in prior studies, it is not approved for use in cancer. The FDA is allowing the use of orteronel and itraconazole in this research study. In addition to its antifungal properties, itraconazole was discovered to function to block angiogenesis (blood vessel formation to tumors) to block a cellular pathway thought to be important in prostate cancer known as the Hedgehog pathway. Investigators hypothesize that blocking male sex hormone production with orteronel will increase reliance on the Hedgehog pathway in prostate cancer cells which can then be blocked with itraconazole and that the combination of these two drugs will be more effective than either alone.
