Vitamin D treatment study for Black men with prostate cancer
Treatments studied
Part of Cancer, Kidney & urinary clinical trials.
This early-phase study looks at how vitamin D replacement affects the immune system in Black/African American men with prostate cancer. It’s testing whether bringing vitamin D levels into a healthier range changes immune signals that may matter for cancer health.

This study tests a personalized care plan to help Black and African American men who have finished treatment for prostate cancer. The goal is to see if the plan improves health understanding and follow-up care.
This study looks at whether giving certain prostate cancer treatments at home (instead of the clinic) works as well for Black men. If you qualify, you may get your regular treatment at home with a nurse.
This trial tests whether taking vitamin D for 8 weeks can improve immune function in Black or West African men with prostate cancer. It compares effects in men with localized cancer versus those whose cancer has spread.
This trial studies whether taking vitamin D while you are on prostate hormone therapy (ADT) affects your health outcomes. It may help by keeping vitamin D levels in a safe range during treatment.
This study looks at how vitamin D levels affect treatment results in women with locally advanced cervical cancer who are about to start chemoradiation (chemotherapy plus radiation). It aims to see if higher vitamin D is linked to better outcomes.
This study looks at vitamin D levels and how they relate to overall health in British African-Caribbean women. It may help researchers understand whether vitamin D support or lifestyle changes could benefit this group.
