- Brief Summary
This is a Phase 1/2, open-label, FIH study designed to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PDy), and antineoplastic activity of RLY-4008, a potent and highly selective FGFR2 inhibitor, in patients with unresectable or metastatic cholangiocarcinoma (CCA) and other solid tumors. The study consists of 3 parts: a dose escalation (Part 1), a dose expansion (Part 2), and an extension (Part 3).

Group Intervention Description Part 1: Dose Escalation RLY-4008 Multiple doses of RLY-4008 for oral administration. Part 2: Dose Expansion RLY-4008 Oral dose of RLY-4008 as determined during Part 1 Dose Escalation. Part 3: Extension RLY-4008 Oral dose of RLY-4008 as determined during Part 1 Dose Escalation. Part 4: Rollover RLY-4008 Oral dose of RLY-4008 as determined during Part 1 Dose Escalation.
- Primary Outcome Measures
Name Time Method Part 1 and Part 4: Number of patients with adverse events and serious adverse events Every cycle (4-week cycles) until study discontinuation, approximately 24 months Part 1: Determination of maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D) of RLY-4008 Cycle 1 (4-week cycle) of treatment for MTD and at the end of every cycle (4-week cycles) for RP2D until study discontinuation, approximately 24 months Part 2 and Part 3: Objective Response Rate (ORR) assessed by Independent Review Committee per RECIST v1.1 Approximately every 8 weeks during treatment and every 12 weeks after the last dose in the absence of progressive disease, approximately 36 months Part 4: Number of patients with dose interruptions Every 28-day cycle until end of treatment, approximately 24 months. Part 4: Number of patients with dose reductions Every 28-day cycle until end of treatment, approximately 24 months. Part 4: Number of patients with dose discontinuations Every 28-day cycle until end of treatment, approximately 24 months.
