Clinical Trial 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.

Description:

Non-melanoma cutaneous carcinomas [NMSCs], predominantly squamous cell carcinomas [SCCs], as well as basal cell carcinomas [BCCs], are the most common malignancies occurring in kidney transplant recipients [KTRs]. SCCs and BCCs, account for more than 90% of NMSCs in KTRs. New NMSCs in KTRs with a prior NMSC develop at 3-times the rate reported in non-KTRs with the same clinical history. The unique aggressiveness of SCCs in KTRs increases patient morbidity, due to the high rate of new lesions requiring treatment, frequently surgical excision. This non-fatal morbidity also results in significant medical costs. KTR SCCs have a greater potential for metastasis, and death. Reduction in the incidence and complications associated with SCCs, in particular, and more generally, overall NMSCs, as well as Actinic Keratoses, would mark a significant advance in the management of KTRs.

Specific Aims of this study are: To evaluate the effects of oral nicotinamide 2 grams/day, given in two divided doses, for 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; To demonstrate our ability to create a system for diagnosing, capturing, and recording all new non-melanoma skin cancers which develop in stable chronic kidney transplant recipients with a history of at least one non-melanoma skin cancer while receiving oral nicotinamide 2 grams/day, given in two divided doses, for 12-months, versus matched placebo; To evaluate the effects of oral nicotinamide 2 grams/day, given in two divided doses, for 12-months, versus matched placebo, on sirtuin enzymatic activity in chronic kidney transplant recipients with a history of at least one non-melanoma skin cancer; To evaluate the safety and tolerability of oral nicotinamide 2 grams/day, given in two divided doses, for 12-months, versus matched placebo, in stable chronic kidney transplant recipients with a history of at least one non-melanoma skin cancer; To evaluate the effects of oral nicotinamide 2 grams/day, given in two divided doses, for 12-months, versus matched placebo, on serum phosphorus concentrations in stable chronic kidney transplant recipients with a history of at least one non-melanoma skin cancer.
