RAD140 Part A and Part BRAD140Part A, Dose Escalation: Patients will be assigned sequentially to escalating doses of RAD140. Part B, Safety Expansion: Once the maximum tolerated dose (MTD) has been identified and/or a recommended dose escalation (RDE) has been determined, additional patients will be enrolled to further evaluate the safety, tolerability and preliminary clinical activity of the recommended dose.
