What this study is about

Researchers are testing whether nicotinamide helps prevent new non-melanoma skin cancers (NMSC) in people with chronic lymphocytic leukemia (CLL). Participants will take either nicotinamide or a placebo for two years. The trial will stop if there's no difference between the groups, meaning that nicotinamide doesn't help prevent NMSCs.
