Vitamin D for Prostate Endocrine Therapy
NCT05838716
This study is recruiting at 51 US sites in 14 states, according to its ClinicalTrials.gov record last updated .
Summary
This phase III trial tests whether high-dose vitamin D works in treating androgen-deprivation therapy (ADT)-induced bone loss in patients with prostate cancer who are undergoing androgen-deprivation therapy. Vitamins are substances that the body needs to grow and develop normally. Vitamin D helps the body absorb calcium. Calcium is one of the main building blocks of bone. A lack of vitamin D can lead to bone diseases such as osteoporosis or rickets.
