Vitamin d trial aims to strengthen immune system in black men with prostate cancer
NCT ID NCT07598032
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This phase 3 trial tests whether daily vitamin D supplements can improve immune function and quality of life in Black/West African men with prostate cancer who have low vitamin D levels. Researchers will compare men with localized disease to those with advanced cancer, tracking immune markers and cancer progression over up to 3 years. The study aims to show that correcting vitamin D deficiency may help slow the disease and improve well-being.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
vitamin D (cholecalciferol) 2000 IU daily
What this could lead to
If it works, this could show that correcting vitamin D deficiency improves immune function and quality of life, and may help slow prostate cancer progression in Black/West African men.
What could go wrong
This is an early-stage trial with only 200 participants, so results may not apply to all men. Vitamin D supplements may not significantly affect cancer outcomes, and long-term benefits are uncertain.
