Brief Summary

Skin cancers and pre-cancerous growths (called actinic keratoses, "AKs"), that aren't melanomas, develop in patients with a kidney transplant at excessive rates. When these pre-cancerous AKs, and "non-melanoma" skin cancers occur in kidney transplant patients, they tend to be aggressive, and require frequent medical procedures, often surgery, for the removal of the skin cancers. If not removed adequately the pre-cancers can develop into skin cancers, and the skin cancers, if not removed, may spread, and even cause death. Reducing the occurrence and complications of these skin cancers and pre-cancers in kidney transplant patients with a safe, effective, well-tolerated treatment taken by mouth would be an important medical advance. We are testing oral nicotinamide (NAM)-a B-vitamin compound-for that purpose. Approximately fifty kidney transplant patients who have had at least one non-melanoma skin cancer in the past, will be given randomized to receive NAM, 1 gram twice daily by mouth, or identical pills without NAM, and followed for 1 year to see if NAM treatment reduces the numbers of pre-cancerous AKs, and non-melanoma skin cancers they develop. Patients will be asked to come to the clinic for 3 follow up visits (every 4 months for up to 12 months). They will receive a full body skin exam by a dermatologist, have detailed counting of AKs and biopsies for any suspicious lesions as standard of care. Blood will also be drawn as well as a urine sample obtained at each visit for safety assessment and storage. We will also ask them to answer a series of questions about dietary patterns and intake of whole foods and supplements.

Outcome Measures

Primary Outcomes (1)

  • Effects of oral nicotinamide on AKs

    To evaluate the effects of oral nicotinamide 1gram/day, given in two divided doses, for 9- 12-months, versus matched placebo, on the total number of actinic keratoses which develop in stable chronic kidney transplant recipients with a history of at least one non-melanoma skin cancer (keratinocyte carcinoma). To evaluate the effects of oral nicotinamide 1gram/day, given in two divided doses, for 9- 12-months, versus matched placebo, on the total number of actinic keratoses which develop in stable chronic kidney transplant recipients with a history of at least one non-melanoma skin cancer (keratinocyte carcinoma).

  • Internal malignancy, metastatic SCC, or invasive melanoma within the past 5-years
  • Overwhelming numbers of current skin cancers or large areas of confluent skin cancer at baseline preventing accurate assessment and counting of new skin cancers
  • Field treatment for AKs within the past 4-weeks, preventing accurate assessment of AKs
  • Patients begun on acitretin or other oral retinoids, or mTOR inhibitors within the past 6-months (If stably taking for more than six months, they may participate)
  • Gorlin's syndrome or other genetic skin cancer syndrome
  • Patients unavailable for follow-up for the duration of the study because of social/ geographical reasons, or general frailty
  • Pregnancy or lactation (all women of childbearing will be required to use contraception throughout the study)
  • Patients taking supplemental NAM within the past 4-weeks
