Vitamin D for Prostate Endocrine Therapy (NCT05838716)
High-dose Vitamin D Supplementation for ADT-Induced Bone Loss in Older Prostate Cancer Patients
🩺 Plain-English Summary (8th-Grade Level)
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. This trial may help researchers determine if high-dose vitamin D helps keep bones strong, lowers number of falls, and lessens fatigue in men getting androgen-deprivation therapy.
