Revolution Medicines to Present Interim Data at ENA 2020 from Phase 1b/2 Clinical Trial Combining RMC-4630 with Cobimetinib for RAS-Addicted Solid Tumors

REDWOOD CITY, Calif., Oct. 12, 2020 (GLOBE NEWSWIRE) — Revolution Medicines, Inc. (Nasdaq: RVMD), a clinical-stage precision oncology company developing targeted therapies to inhibit frontier targets in RAS-addicted cancers, today announced that interim data from the company’s ongoing Phase 1b/2 clinical trial (RMC-4630-02) evaluating the combination of RMC-4630 and cobimetinib (Cotellic^®) will be reported in an oral presentation in a plenary session at the upcoming EORTC-NCI-AACR 32^nd Symposium on Molecular Targets and Cancer Therapeutics (ENA 2020) being held virtually October 24-25, 2020.
The ongoing Phase 1b/2 RMC-4630-02 trial is an open-label, dose-escalation and dose-expansion study designed to evaluate the safety, tolerability, pharmacokinetic, and pharmacodynamic profiles of RMC-4630 and cobimetinib in adult patients with relapsed/refractory solid tumors that harbor specific genomic mutations. The study tested several dosing regimens, including intermittent RMC-4630 plus daily or intermittent cobimetinib. Preliminary data to be presented at ENA 2020 will focus on safety, tolerability and pharmacokinetic findings from combination dosing regimens.“We are gratified that data from our ongoing combination trial of RMC-4630 and cobimetinib were selected for presentation at ENA 2020. Drug combinations will likely be critical to defeating inherent drug resistance mechanisms exploited by RAS-addicted cancers,” said Steve Kelsey, M.D., president of research and development at Revolution Medicines. “We remain keenly focused on testing the clinical hypothesis that RMC-4630 may be useful as a backbone for various combination treatments designed for different cancers with distinct molecular profiles.”Details of the upcoming oral presentation at ENA 2020 are as follows:Title: Intermittent dosing of RMC-4630, a potent, selective inhibitor of SHP2, combined with the MEK inhibitor cobimetinib, in a Phase 1b/2 clinical trial for advanced solid tumors with activating mutations of RAS signalingSession: Plenary Session 1: Late-Breaking and Best Proffered PapersPresenting Author: Johanna C.

RMC-4630 and cobimetinib are targeted inhibitors of oncogenic proteins at distinct positions within the RAS signaling cascade that is frequently exploited by human cancers and may develop adaptive resistance to single agent treatment. RMC-4630 is a potent and orally bioavailable small molecule designed to selectively inhibit the activity of SHP2, an upstream cellular protein that plays a key role in modulating cell growth by transmitting signals from receptor tyrosine kinases to RAS. Cobimetinib, marketed in the U.S. by Genentech, a member of the Roche group, inhibits the activity of MEK, a downstream effector of RAS that affects cell survival and growth. Cobimetinib is approved in the U.S. for the treatment of patients with BRAF^V600E or BRAF^V600K mutation-positive unresectable or metastatic melanoma in combination with vemurafenib (Zelboraf^®).  About RMC-4630RMC-4630 is currently being evaluated in a Phase 1 monotherapy clinical trial (RMC-4630-01) for a range of tumor types featuring specific, molecularly-defined oncogenic mutations, a Phase 1b/2 trial (RMC-4630-02) in combination with cobimetinib in patients with relapsed/refractory solid tumors displaying specific genomic mutations, a Phase 1b study (CodeBreaK 101) in combination with AMG 510 in patients with advanced solid tumors harboring the KRAS^G12C mutation, and a Phase 1 study in combination with pembrozilumab in patients with advanced malignancies.The SHP2 inhibitor program, including RMC-4630, is the focus of an exclusive global research, development and commercialization agreement with Sanofi.About Revolution Medicines, Inc.Revolution Medicines is a clinical-stage precision oncology company developing novel targeted therapies to inhibit high-value frontier targets in RAS-addicted cancers.
