CAMBRIDGE, Mass., Sept. 03, 2020 (GLOBE NEWSWIRE) — Relay Therapeutics, Inc. (Nasdaq: RLAY), a clinical-stage precision medicine company transforming the drug discovery process by leveraging unparalleled insights into protein motion, today announced the first patient has been dosed in a first-in-human clinical trial of RLY-4008 enriched for patients with intrahepatic cholangiocarcinoma (ICC) and other advanced solid tumors harboring a fibroblast growth factor receptor 2 (FGFR2) alteration. RLY-4008 is the only selective small molecule inhibitor of FGFR2 in clinical development.
“We are excited to bring RLY-4008, our second targeted therapeutic, into clinical development,” said Don Bergstrom, M.D., Ph.D., executive vice president of R&D of Relay Therapeutics. “FGFR2 altered tumors are known to respond clinically to pan-FGFR inhibitors but with limited benefit to patients. RLY-4008 is an exquisitely selective and purpose-built medicine, discovered with our Dynamo platform, designed to dramatically alter the course of disease for patients with FGFR2 altered cancers.”The first-in-human trial is designed to evaluate the safety and tolerability of RLY-4008 in patients with advanced or metastatic solid tumors. The trial will predominantly enroll patients with molecularly identified FGFR2 fusions, mutations and amplifications during the dose escalation phase. Given RLY-4008’s strong preclinical activity against both primary oncogenic alterations and acquired pan-FGFR inhibitor resistance mutations, the trial is enrolling patients who are naïve to pan-FGFR inhibitors as well as those who have been exposed to prior therapy with pan-FGFR inhibitors. In the expansion part of the trial, five cohorts are planned to evaluate genetically defined populations: 1) ICC patients with a FGFR2 fusion previously treated with a pan-FGFR inhibitor; 2) ICC patients with a FGFR2 fusion not previously treated with a pan-FGFR inhibitor; 3) patients with an FGFR2 fusion and solid tumor other than ICC; 4) advanced, unresectable solid tumor patients with focal FGFR2 amplification; 5) advanced, unresectable solid tumor patients with an oncogenic FGFR2 mutation. Trial objectives include evaluating safety, tolerability, pharmacokinetics and anti-tumor efficacy. The trial is designed to enroll up to 125 patients.About RLY-4008
RLY-4008 is a potent, selective and oral small molecule inhibitor of FGFR2, a receptor tyrosine kinase that is frequently altered in certain cancers. FGFR2 is one of four members of the FGFR family, a set of closely related proteins with highly similar protein sequences and properties. Preclinically, RLY-4008 demonstrated FGFR2-dependent killing in cancer cell lines, while showing minimal inhibition of other targets, including other members of the FGFR family. RLY-4008 is currently being evaluated in a first-in-human trial designed to treat patients with advanced or metastatic FGFR2-altered solid tumors.
