Rationale: DCC-2036 is a potent broad spectrum inhibitor of BCR-ABL kinase. Inhibition of BCR-ABL has been validated for effective treatment of chronic myeloid leukemia (CML). The emergence of mutant forms of BCR-ABL which resist inhibition by imatinib, dasatinib, and nilotinib is associated with loss of efficacy in treatment of the disease. DCC-2036 is a potent inhibitor of resistant mutants of BCR-ABL including the T315I mutation, and would therefore be expected to effectively treat patients who fail to respond to other BCR-ABL inhibitors. DCC-2036 also inhibits FLT3-ITD, TIE2, KDR, LYN and TRKA kinases. Purpose: to assess the safety and tolerability in patients after continuous administration of DCC-2036 and to determine recommended doses for the conduct of a Phase 2 efficacy trial.
