REFOCUS: A First-in-Human Study of Highly Selective FGFR2 Inhibitor, RLY-4008, in Patients With ICC and Other Advanced Solid Tumors
United States, Australia, France490 participantsStarted 2020-09-02
Plain-language 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 4 parts: a dose escalation (Part 1), a dose expansion (Part 2), and an extension (Part 3) and a rollover (Part 4).

Key Inclusion Criteria
* Histologically or cytologically confirmed unresectable or metastatic solid tumor
* Documented FGFR2 gene fusion, mutation, or amplification per local testing of blood and/or tumor
* Patient must have measurable disease per RECIST v1.1
* Patient has ECOG performance status of 0-1
* Patient must have disease that is refractory to standard therapy, disease that has not adequately responded to standard therapy, disease for which standard or curative therapy does not exist, or the patient must be intolerant to or have declined standard therapy
* Part 2 dose expansion patients with Cholangiocarcinoma:
* Group 1: CCA patients with an FGFR2 fusion previously treated with an FGFRi
* Group 2: CCA patients with an FGFR2 fusion with prior chemotherapy but not previously treated with an FGFRi
* Group 6: CCA patients with an FGFR2 fusion with no prior chemotherapy and not previously treated with an FGFRi. Prior adjuvant/neo-adjuvant treatment completed \>6 months before enrollment is acceptable. Up to 2 cycles of palliative chemotherapy are allowed during screening
* Group 7: CCA patients with an FGFR2 mutation or amplification and not previously treated with an FGFRi. Note: For Group 7, patients with confirmed diagnosis of unresectable or metastatic CCA with an FGFR2 fusion are not eligible.
* Part 2 dose expansion patients with other solid tumors (NOT Cholangiocarcinoma):
* Group 3: Non-CCA patients with an FGFR2 fusion and not previously trea…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Part 1 and Part 4: Number of patients with adverse events and serious adverse events
Timeframe: Every cycle (4-week cycles) until study discontinuation, approximately 24 months
2
Part 1: Determination of maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D) of RLY-4008
Timeframe: 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
3
Part 2 and Part 3: Objective Response Rate (ORR) assessed by Independent Review Committee per RECIST v1.1
Timeframe: Approximately every 8 weeks during treatment and every 12 weeks after the last dose in the absence of progressive disease, approximately 36 months
4
Part 4: Number of patients with dose interruptions
Timeframe: Every 28-day cycle until end of treatment, approximately 24 months.
5
Part 4: Number of patients with dose reductions
Timeframe: Every 28-day cycle until end of treatment, approximately 24 months.
6
Part 4: Number of patients with dose discontinuations
Timeframe: Every 28-day cycle until end of treatment, approximately 24 months.
