  1. Renal and liver function data are reported as the number of participants with at least one CTCAE adverse event in the 12-month dose escalation phase of the study. Serious adverse events are reported as the number of events (number of participants)
  2. R+ amount of allopurinol (milligrams) above creatinine clearance (CrCl)-based dose, GGT gamma-glutamyl transferase, ALP alkaline phosphatase, AST aspartate aminotransferase, ALT alanine aminotransferase
