Conference Call and Webcast today at 4:30 p.m. Eastern Time

REDWOOD CITY, Calif., August 9, 2022 – (GLOBE NEWSWIRE) – Revolution Medicines, Inc. (Nasdaq: RVMD), a clinical-stage oncology company developing targeted therapies for RAS-addicted cancers, today announced its financial results for the quarter ended June 30, 2022 and provided an update on corporate progress.

“We continue making progress in the development of innovative medicines on behalf of patients with RAS-addicted cancers, highlighted particularly by the advancement into clinical development of the first two drug candidates from our extensive RAS(ON) Inhibitor portfolio,” said Mark A. Goldsmith, M.D., Ph.D., chief executive officer and chairman of Revolution Medicines. “We began dosing patients in a Phase 1/1b trial evaluating RMC-6236 in patients with tumors bearing various KRAS^G12 mutations, and study site activation is underway for a Phase 1/1b trial of RMC-6291 that shortly will begin dosing patients with tumors specifically bearing a KRAS^G12C mutation. We expect these exciting clinical-stage compounds will be followed by additional groundbreaking RAS(ON) Inhibitor drug candidates from our collection, including RMC-9805, which we believe is the first oral, covalent inhibitor of KRAS^G12D, the most common RAS variant causing human cancer.

“Additionally, data from Amgen’s CodeBreaK 101c study presented at the International Association for the Study of Lung Cancer (IASLC) demonstrated the combination of RMC-4630 and sotorasib is safe and tolerable and provided encouraging initial evidence of promising and durable clinical activity in patients with non-small cell lung cancer (NSCLC) bearing a KRAS^G12C mutation. These exploratory findings support our goal of evaluating the potential benefit of combining RMC-4630 with our own RAS(ON) Inhibitors in development. Further, RMC-4630-03, our Phase 2 study evaluating this drug combination, continues enrolling patients with NSCLC bearing the KRAS^G12C mutation who have not previously received a KRAS^G12C inhibitor.

“To support our growing pipeline of development-stage programs, Revolution Medicines recently completed an upsized public equity financing, raising gross proceeds of $265 million. These funds extend the company’s operating runway and enable us to continue executing our robust product development strategy to combat RAS-addicted cancers.”

Second Quarter 2022 Clinical and Development Highlights

RAS(ON) Inhibitors

RMC-6236 (RAS^MULTI)

RMC-6236 is an oral RAS(ON) Inhibitor designed to treat patients with cancers driven by a variety of RAS mutations, including KRAS^G12D, KRAS^G12V and KRAS^G12R. Initially being evaluated as monotherapy, it may also be deployed as a RAS Companion Inhibitor in combination with mutant-selective RAS(ON) Inhibitors.

• The company dosed the first patient in its Phase 1/1b monotherapy clinical trial of RMC-6236 and continues enrolling patients. The Phase 1/1b trial (NCT05379985) is a multicenter, open-label, dose-escalation and dose-expansion study of RMC-6236 in patients with advanced solid tumors harboring selected KRAS^G12 mutations, including KRAS^G12D, KRAS^G12V and KRAS^G12R. To the company’s knowledge, RMC-6236 is the first oral, direct RAS inhibitor to be deployed against a tumor harboring the KRAS^G12D variant. The company anticipates providing evidence of first-in-class single agent activity for RMC-6236 in 2023.

• In April 2022, the company delivered an oral presentation at the American Association for Cancer Research (AACR) 2022 Annual Meeting demonstrating that RMC-6236 induced significant monotherapy regressions in mouse clinical trials in diverse models of KRAS^G12-mutant NSCLC, colorectal cancer (CRC), and pancreatic cancer. It further showed that RMC-6236 deployed as a RAS Companion Inhibitor in combination with RMC-6291 demonstrated enhanced anti-tumor activity in KRAS^G12C NSCLC and CRC models that were refractory to single agent treatments.

RMC-6291 (KRAS^G12C)

RMC-6291, an oral, selective, covalent inhibitor of KRAS^G12C(ON) designed to treat patients with cancers driven by the KRAS^G12C mutant, is the first of the company’s mutant-selective RAS(ON) Inhibitors to enter clinical development.

• Study site activation is ongoing under an investigational new drug (IND) application for a Phase 1/1b trial (NCT05462717) of RMC-6291. The trial is a multicenter, open-label, dose-escalation and dose-expansion study of RMC-6291 monotherapy in patients with advanced KRAS^G12C-mutant solid tumors. The company expects to announce dosing of the first patient in a monotherapy dose-escalation study of this compound in the second half of 2022 and to provide preliminary evidence of superior activity for this compound in 2023.

• In April 2022, the company delivered an oral presentation at AACR showing that RMC-6291 demonstrated superior preclinical efficacy over adagrasib (MRTX849), Mirati’s KRAS^G12C inhibitor, in a head-to-head mouse clinical trial in models of KRAS^G12C NSCLC.

RMC-9805 (KRAS^G12D)

RMC-9805 is an oral, selective, covalent inhibitor of KRAS^G12D(ON), the most common driver of RAS-addicted human cancers, predominantly among patients with CRC, pancreatic cancer or NSCLC. The company believes RMC-9805 is the first oral, covalent inhibitor of KRAS^G12D.

• The company expects to announce dosing of the first patient in a monotherapy dose-escalation study of RMC-9805 in mid-2023.

• In April 2022, the company delivered an oral presentation at AACR demonstrating that RMC-9805 produced profound and durable tumor regressions, including complete regressions, in diverse preclinical models of KRAS^G12D CRC and pancreatic cancer.

RMC-8839 (KRAS^G13C)

RMC-8839 is an oral, selective, covalent inhibitor of KRAS^G13C(ON). The company believes RMC-8839 is the first compound to directly inhibit KRAS^G13C, an important therapeutic target primarily for NSCLC and select CRC patients unserved by a targeted RAS inhibitor.

• For 2022 and 2023 the company currently intends to concentrate its development resources on its three most advanced RAS(ON) Inhibitors (RMC-6236, RMC-6291 and RMC-9805) and two RAS Companion Inhibitors that are in the clinic (RMC-4630 and RMC-5552) and therefore expects to determine the timing for announcement of initiating clinical evaluation of RMC-8839 at a future date.

• In April 2022, the company delivered an oral presentation at AACR demonstrating that RMC-8839 induced profound and durable tumor regressions in models of KRAS^G13C NSCLC. The results also showed that normal RAS proteins contribute to oncogenic signaling in KRAS^G13C tumor lines, providing the rationale to pursue combination strategies featuring RMC-8839 and RMC-4630, the company’s SHP2 inhibitor capable of inhibiting normal RAS.

RAS Innovation Engine

The company is leveraging its innovative tri-complex inhibitor platform and advanced cancer discovery capabilities to identify additional oral RAS(ON) Inhibitors to target RAS variants driving RAS-addicted cancers that are unserved by a targeted RAS inhibitor.

• The company is conducting multiple pipeline expansion programs focused on RAS mutation hotspots G12 (e.g., G12V and G12R), G13 (e.g., G13D) and Q61.

• The company expects to nominate a fifth RAS(ON) Inhibitor development candidate in the second half of 2022.

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 (also known as SAR442720) continues development under the company’s global SHP2 development and commercialization partnership with Sanofi.

RMC-4630 and KRAS^G12C Inhibitor Lumakras^™ (sotorasib)

• CodeBreaK 101c: Amgen recently reported preliminary results from its CodeBreaK 101c trial, an exploratory Phase 1b study evaluating the combination of RMC-4630 with the KRAS^G12C inhibitor sotorasib in patients with advanced KRAS^G12C-mutated solid tumors, at the International Association for the Study of Lung Cancer (IASLC) 2022 World Conference on Lung Cancer. These results demonstrated that the combination was safe and tolerable, and showed promising early clinical activity in NSCLC patients with KRAS^G12C mutations, particularly in patients who were KRAS^G12C inhibitor-naïve.

• RMC-4630-03: Revolution Medicines continues enrolling patients in its global Phase 2 trial RMC-4630-03 (NCT05054725), a Phase 2 multicenter, open-label study of RMC-4630 in combination with sotorasib for patients with NSCLC with a KRAS^G12C mutation who have failed prior standard therapy and who have not previously been treated with a KRAS^G12C inhibitor. The company is sponsoring the RMC-4630-03 study under its global SHP2 partnership with Sanofi and conducting the trial in collaboration with Amgen, which is supplying sotorasib to trial sites globally. Revolution Medicines currently expects to provide topline data from this study in 2023.

RMC-4630 and KRAS^G12C Inhibitor adagrasib

• Sanofi is recruiting patients in a Phase 1/2 dose escalation and expansion study under its SHP2 partnership with Revolution Medicines, and in collaboration with Mirati. The study will evaluate RMC-4630 in combination with adagrasib (MRTX849) in patients with previously treated NSCLC bearing a KRAS^G12C mutation.

RMC-4630 and PD-1 Inhibitor KEYTRUDA^® (pembrolizumab)

• Sanofi is conducting a Phase 1 trial evaluating RMC-4630 in combination with pembrolizumab, a PD-1 inhibitor, as first-line treatment for patients with PDL-1 positive NSCLC.

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 intends to combine RMC-5552 with RAS(ON) Inhibitors in patients with cancers harboring RAS/mTOR pathway co-mutations.

• Dose optimization continues in the company’s ongoing Phase 1/1b clinical trial evaluating RMC-5552 monotherapy (NCT04774952). This study is expected to enable combination studies in RAS-addicted cancers. The trial is a multicenter, open-label, dose-escalation study of RMC-5552 monotherapy in patients with refractory solid tumors.

• Previously, the company reported preliminary evidence of clinical activity, and reported updated data from this trial at the American Society of Clinical Oncology (ASCO) Annual Meeting in June 2022. The data reported at ASCO demonstrate marked anti-tumor activity by RMC-5552 in combination with the company’s RAS(ON) Inhibitors in preclinical NSCLC models. The company anticipates disclosing additional evidence of single agent activity in 2023.
