"With growing confidence in our pioneering RAS-focused drug candidate pipeline, we believe Revolution Medicines is poised for a transformative second half of the year. We intend to share significant clinical updates on our most advanced RAS(ON) Inhibitors, RMC-6236 and RMC-6291, through oral presentations at the Triple Meeting and ESMO (Free ESMO Whitepaper) in October," said Mark A. Goldsmith, M.D., Ph.D., chief executive officer and chairman of Revolution Medicines. "Having announced last week our agreement to acquire EQRx to add more than $1 billion in additional capital to our balance sheet, we are in an especially strong position to build on this clinical momentum and continue scientific advances on behalf of patients. We are already planning one or more pivotal single agent clinical trials for RMC-6236 as well as for our first in-pipeline combination trial featuring RMC-6236 and RMC-6291."
Clinical and Development Highlights
Investigational RAS(ON) Inhibitors
RMC-6236 (RASMULTI)
RMC-6236 is an oral, RAS-selective, first-in-class RAS(ON) Inhibitor designed to treat patients with cancers driven by a wide range of common RAS mutations. Initially being evaluated as monotherapy, it may also be evaluated as a RAS Companion Inhibitor in combination with mutant-selective RAS(ON) Inhibitors and in other combination treatments.
The ongoing Phase 1/1b monotherapy trial (NCT05379985) is a multicenter, open-label, dose-escalation and dose-expansion study of RMC-6236 in patients with advanced solid tumors harboring select KRASG12 mutations, including KRASG12D, KRASG12V and KRASG12R. Preliminary data have shown promising evidence of anti-tumor activity at generally well tolerated dose levels. A maximum tolerated dose has not yet been defined and dose escalation is ongoing.
An update on the clinical antitumor activity of RMC-6236 in patients with non-small cell lung cancer (NSCLC) or pancreatic cancer will be presented as a Proffered Paper (oral presentation) during the Developmental Therapeutics session on Sunday, October 22 at the European Society for Medical Oncology Congress 2023 (ESMO) (Free ESMO Whitepaper), and supporting clinical data will be presented at the AACR (Free AACR Whitepaper)-NCI-EORTC AACR-NCI-EORTC (Free AACR-NCI-EORTC Whitepaper) International Conference on Molecular Targets and Cancer Therapeutics (EORTC-NCI-AACR) (Free ASGCT Whitepaper) (Free EORTC-NCI-AACR Whitepaper) (Triple Meeting) in October 2023. Additional details for these presentations will be provided when available.
Based on encouraging data trends thus far for RMC-6236, planning is underway for one or more single agent pivotal clinical trials potentially to begin in 2024.
RMC-6291 (KRASG12C)
RMC-6291, an oral, covalent inhibitor of KRASG12C(ON) designed to treat patients with cancers driven by the KRASG12C mutant, is the first of the company’s mutant-selective RAS(ON) Inhibitors to enter clinical development and the first reported clinical-stage inhibitor of KRASG12C that uses a highly differentiated mechanism of action compared to first-generation compounds.
The ongoing Phase 1/1b monotherapy trial (NCT05462717) is a multicenter, open-label, dose-escalation and dose-expansion study of RMC-6291 in patients with advanced KRASG12C mutant solid tumors. Early findings have shown that RMC-6291 is orally bioavailable, exhibits pharmacokinetics consistent with preclinical findings, and is generally well tolerated in a pharmacologically active range.
The company will provide a first report on initial clinical findings with RMC-6291, including preliminary evidence of differentiation from RAS(OFF) inhibitors, at the Triple Meeting. Details for this presentation will be provided when available.
With encouraging initial clinical experience thus far for RMC-6291, planning is underway for a Phase 1/1b clinical trial to evaluate the combination of RMC-6236 and RMC-6291 potentially to begin in early 2024, in parallel to the continuing single agent evaluation of RMC-6291.
RMC-9805 (KRASG12D)
RMC-9805 is an oral, selective, covalent inhibitor of KRASG12D(ON), the most common driver of RAS-addicted human cancers, predominantly among patients with pancreatic cancer, NSCLC, or colorectal cancer (CRC). The company believes RMC-9805 is the first oral, mutant-selective and covalent inhibitor of KRASG12D.
Study site activation is ongoing under an investigational new drug (IND) application for a monotherapy dose-escalation Phase 1/1b trial of RMC-9805 and the company currently expects to announce dosing of the first patient in this study in the second half of 2023.
RAS Innovation Engine
Beyond the first wave of RAS(ON) Inhibitors, the company continues expanding its preclinical pipeline of RAS(ON) Inhibitor candidates.
RMC-0708 is a potent, oral, selective, first-in-class non-covalent inhibitor of the KRASQ61H(ON) cancer variant. KRASQ61H is found in lung cancer, CRC, pancreatic cancer, and multiple myeloma. RMC-0708 is the company’s first mutant-selective RAS(ON) Inhibitor drug candidate to engage its RAS target non-covalently.
RMC-8839 is a potent, oral, and selective inhibitor of KRASG13C(ON). The company believes RMC-8839 is the first compound to selectively inhibit KRASG13C, an important therapeutic target primarily for NSCLC and select CRC patients unserved by a targeted RAS inhibitor.
The company continues drug discovery efforts in RAS(ON) Inhibitor pipeline expansion programs focused on RAS mutation hotspots including KRASG12R, KRASG13D, and other important targets.
Investigational RAS Companion Inhibitors
RMC-4630 (SHP2)
RMC-4630 is a clinical-stage, oral inhibitor of SHP2, which contributes to tumor survival and growth in many RAS-addicted cancers.
RMC-4630 and KRASG12C Inhibitor Lumakras (sotorasib)
RMC-4630-03 (NCT05054725) is a global, multicenter, open-label Phase 2 study of RMC-4630 in combination with sotorasib for patients with NSCLC with a KRASG12C mutation who have failed prior standard therapy and who have not previously been treated with a KRASG12C inhibitor that the company is conducting in collaboration with Amgen.
The RMC-4630-03 study is fully enrolled, and the company plans to review a complete data set from the study when available. Decisions about future development of RMC-4630 will take into account this analysis and other considerations, including the potential of RMC-6236 as a RAS Companion Inhibitor. The company no longer plans to share topline data from the RMC-4630-03 study prior to disclosing decisions about future development of the compound.
RMC-5552 (mTORC1/4EPB1)
RMC-5552 is a first-in-class, bi-steric mTORC1-selective inhibitor designed to suppress phosphorylation and inactivation of 4EBP1 in cancers with hyperactive mTORC1 signaling, including certain RAS-addicted cancers. The company plans to evaluate RMC-5552 in combination with RAS(ON) inhibitors for patients with cancers harboring a RAS mutation and co-occurring mutations in the mTOR signaling pathway.
Dose optimization continues in the company’s ongoing multicenter, open-label, Phase 1/1b dose-escalation study evaluating RMC-5552 monotherapy in patients with refractory solid tumors (NCT04774952).
The company currently expects to provide additional characterization of the single agent profile for this compound at the upcoming Triple Meeting in October 2023.
