Experimental: RAD140 Part A and Part B
Part 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. |
Drug: RAD140
RAD140 will be supplied as formulated drug-in-capsules for oral administration. |
