ClinConnect Summary
This clinical trial is studying whether a form of Vitamin B3 called nicotinamide can help prevent skin cancer in patients who have received organ transplants, such as kidney, liver, heart, or lung transplants. Many of these patients are at a higher risk of developing skin cancer due to the medications they take to prevent their bodies from rejecting the new organ. The trial will involve about 396 adult participants who have had at least one skin cancer in the past and are currently taking immune-suppressing medications.
To take part in the study, participants need to be at least 18 years old and must have received their organ transplant at least two years ago. They should also be able to attend follow-up visits during the trial. Those who qualify will receive either nicotinamide or a placebo (a pill that looks the same but contains no active medication) for up to four years. This trial aims to determine if nicotinamide is effective and safe for preventing skin cancer, which could greatly improve the long-term health and quality of life for organ transplant recipients.
