NCT ID NCT07241585
First seen Nov 21, 2025 · Last updated Jun 23, 2026 · Updated 25 times
Summary
This study tests whether taking high-dose vitamin D for 6 days before photodynamic therapy (PDT) can improve the immune system's ability to fight nonmelanoma skin cancer. About 54 adults scheduled for Mohs surgery will be randomly assigned to vitamin D or placebo. Researchers will compare immune markers in the tumor tissue to see if the combination triggers a stronger immune response.
