Cyclophosphamide and Dexamethasone for the Treatment of Metastatic Castration Resistant Prostate Cancer (NCT05479578)
A Phase I Study of Oral Metronomic Dosing of Oral Cyclophosphamide with Dexamethasone for Metastatic Castration Resistant Prostate Cancer
🩺 Plain-English Summary (8th-Grade Level)
This phase I trial tests the safety and side effects of cyclophosphamide given together with dexamethasone in treating patients with castration resistant prostate cancer that has spread to other places in the body (metastatic). Chemotherapy drugs, such as cyclophosphamide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving low doses of cyclophosphamide daily may reduce side effects. Dexamethasone is a corticosteroid drug that is used to treat some of the problems caused by chemotherapy treatment. The combination of cyclophosphamide and dexamethasone may work better in treating patients with castration resistant prostate cancer.

Usually NOT eligible if any of the following apply:
- Exclusion Criteria:
- Any condition that would prohibit the understanding or rendering of informed consent
- A history of any other active malignancy with progression and requiring treatment/intervention, with the exception of cutaneous malignancies such as basal cell carcinoma, squamous cell carcinoma, melanoma, or the type of malignancy being studied in this protocol
