This is a first-in-human, multicenter, open-label study consisting of 2 phases. Phase 1 is a dose escalation study of RXDX-105 (formerly known as CEP-32496) in patients with advanced solid tumors aimed at defining the recommended Phase 2 dose (RP2D) and schedule for administration. Phase 1b is a dose expansion in approximately 90 patients with advanced solid tumors with specific histologies and/or molecular alterations of interest. Patients in Phase 1b will be treated at the RP2D determined in Phase 1.
Name: RXDX-105
Description: During Phase 1/1b, subjects will receive daily oral doses of RXDX-105 in 28-day cycles (except for Day 2 of Cycle 1). To determine the recommended Phase 2 dose (RP2D), doses will be administered in an escalated fashion starting at 20 mg/day. During Phase 1b, subjects will be administered the RP2D in 28-day treatment cycles until documented radiographic progression, unacceptable toxicity, withdrawal of consent, or protocol specified parameters to stop treatment.Type: DrugRXDX-105
Description: From signing of the informed consent up to approximately 12 months
Measure: Phase 1: Dose Limiting Toxicities Time: Approximately 12 monthsDescription: From signing of the informed consent up to approximately 12 months
Measure: Phase 1: Occurrence of Adverse Events Time: Approximately 12 monthsDescription: To further assess the safety profile and tolerability of RXDX-105 at the RP2D
Measure: Phase 1b: Occurrence of Adverse Events Time: Approximately 12 monthsDescription: Objective response rate is defined as the proportion of patients with advanced solid tumors achieving best overall response of complete response (CR), or partial response (PR), as assessed using RECIST v1.1
Measure: Phase 1b: Objective Response Rate Time: Approximately 12 monthsDescription: The duration of objective response is defined as the time interval from the date of first documented response (CR or PR) to disease progression or death, whichever occurs first
Measure: Phase 1b: Duration of Objective Response Time: Approximately 12 monthsDescription: Clinical benefit rate is defined as the proportion of patients achieving a complete response (CR), partial response (PR) or stable disease (SD) for 6 months
Measure: Phase 1b: Clinical Benefit Rate Time: Approximately 12 monthsSingle Group Assignment
