Multiple clinical trials sponsored by the industry sponsor Exelixis have evaluated intravenously administered XL228. These early-stage Phase 1 dose-escalation studies investigated the safety, pharmacokinetics, and pharmacodynamics of the drug in patients with advanced solid cancers, lymphoma, chronic myeloid leukemia, or Philadelphia chromosome-positive acute lymphoblastic leukemia. Recruitment for these oncological and hematological trials has reached a terminated status.
