Revolution Medicines Reports Third Quarter 2020 Financial Results and Update on Corporate Progress

Recommended Phase 2 Dose and Schedule Selected for Further Evaluation of RMC-4630 as Monotherapy and RMC-4630 plus Cobimetinib Combination

First-in-Class RAS(ON) Inhibitor Programs for Five Targets in Lead Optimization

REDWOOD CITY, Calif., Nov. 12, 2020 (GLOBE NEWSWIRE) — Revolution Medicines, Inc. (Nasdaq: RVMD), a clinical-stage precision oncology company focused on developing targeted therapies to inhibit frontier targets in RAS-addicted cancers, today announced its financial results for the third quarter and nine months ended September 30, 2020, and provided a corporate update.

“Revolution Medicines is a leader in developing innovative medicines and treatment strategies on behalf of patients with RAS-addicted tumors. We are advancing a growing portfolio consisting of both direct RAS(ON) Inhibitors and RAS Companion Inhibitors designed to enable combination approaches, including RMC-4630 targeting SHP2, RMC-5552 targeting mTORC1, and inhibitors of SOS1,” said Mark A. Goldsmith, M.D., Ph.D., chief executive officer and chairman of Revolution Medicines.

“In our RAS Companion Inhibitor portfolio, we continue to make important strides with RMC-4630, our clinical stage inhibitor of SHP2.   We selected the recommended Phase 2 dose and schedule (RP2DS) for both our monotherapy trial (RMC-4630-01) and the RMC-4630/cobimetinib (Cotellic®) combination arm of the RMC-4630-02 clinical trial, and each trial will further evaluate the appropriate RP2DS in expansion cohorts of molecularly selected patients. As anticipated, we recently dosed a first patient in a new combination study of RMC-4630 with the third-generation EGFR inhibitor, osimertinib (Tagrisso®). We also entered into a new clinical collaboration with AstraZeneca to study RMC-4630 in combination with an emerging asset targeting KRAS^G12C from AstraZeneca’s portfolio.

“In addition, we accelerated growth of our RAS(ON) Inhibitor platform, which has produced a collection of potent, cell-active inhibitors of diverse oncogenic RAS variants responsible for the vast majority of RAS-addicted cancers.  Previously, we demonstrated significant anti-tumor effects of a representative potent and oral inhibitor of KRAS^G12C(ON). During the third quarter we confirmed the broad scope of our platform by demonstrating that representative KRAS^G12D(ON) inhibitors likewise induced tumor regressions in a preclinical model of human pancreatic cancer harboring the oncogenic KRAS^G12D mutation.   We have advanced our KRAS^G12C/NRAS^G12C(ON), KRAS^G12D(ON), KRAS^G13C(ON) and KRAS^G12V(ON) inhibitor programs into lead optimization.”  

R&D Highlights

RAS Companion Inhibitors

• Determined Recommended Phase 2 Dose and Schedule (RP2DS) for single agent RMC-4630 – Completed dose escalation and selected 200 mg administered on a Day 1/Day 2 (D1D2) weekly schedule as the RP2DS. The company plans to evaluate single agent RMC-4630 at the RP2DS in an expansion cohort of patients with gynecologic tumors harboring NF1^LOF mutations, in addition to a small safety/tolerability cohort representing a broader set of histotypes and RAS pathway genotypes.
• Determined RP2DS for RMC-4630 in Combination with the MEK Inhibitor, Cobimetinib – Completed dose escalation and selected RMC-4630 140 mg and cobimetinib 40 mg administered on a Day 1/Day 2 (D1D2) weekly schedule as the RP2DS. The company plans to further evaluate this combination at the RP2DS in expansion cohorts of patients with colorectal cancer harboring KRAS^G12V or KRAS^G12D mutations and others drawing from a broader set of histotypes and RAS pathway genotypes.
• Interim Data Presented at ENA 2020 from Phase 1b/2 Clinical Trial Combining RMC-4630 with Cobimetinib – Interim data reported by investigators support a dual intermittent dosing strategy for RMC-4630 and cobimetinib that appears tolerable and exceeds target plasma exposures for each drug based on preclinical models of RAS pathway-driven cancers that project potential clinical activity. Investigators also reported preliminary evidence of anti-tumor activity in patients with colorectal cancer driven by KRAS mutations.
• RMC-4630 Multi-Cohort Phase 1/2 Clinical Program Expanding as Potential Backbone for Combination Therapies –
  • Dosing and enrollment continue in the Amgen-sponsored Phase 1 study of RMC-4630 in combination with Amgen’s KRAS^G12C(OFF) inhibitor, AMG 510, or sotorasib
  • Dosing and enrollment continue in the Sanofi-sponsored Phase 1 study of RMC-4630 in combination with the PD-1 inhibitor, pembrozilumab (Keytruda^®) 
  • Initiated a study evaluating RMC-4630 in combination with the EGFR inhibitor, osimertinib (Tagrisso^®)
  • Entered into a new clinical collaboration agreement with AstraZeneca to study RMC-4630 in combination with an emerging asset targeting KRAS^G12C from AstraZeneca’s portfolio

• Clinical Results Support Dual Mechanisms of Anti-Tumor Activity by RMC-4630: Tumor Cell-Intrinsic and Stimulation of Immune Response – Data reported by the company from its ongoing RMC-4630-01 trial provide clinical evidence that SHP2 inhibition may act by stimulating arms of the immune system as a second anti-tumor mechanism in addition to its tumor cell-intrinsic benefits. These observations provide further rationale for the ongoing clinical combination study with RMC-4630 and pembrozilumab by Sanofi, the company’s SHP2 collaboration partner.

RAS(ON) Inhibitors

• First-In-Class RAS(ON) Inhibitor Platform – The company’s proprietary tri-complex technology platform enables a highly differentiated approach to inhibiting RAS(ON) with potential biologic advantages. Revolution Medicines is developing a portfolio of compounds that it believes are the first and only RAS(ON) inhibitors to use this mechanism of action. The company has produced potent, cell-active RAS(ON) Inhibitors for variants driving the vast majority of RAS-addicted cancers.
• Inhibitors for Five RAS(ON) Variants in Lead Optimization – KRAS^G12C/NRAS^G12C(ON), KRAS^G12D(ON), KRAS^G13C(ON), and KRAS^G12V(ON) inhibitors are in lead optimization, which include and expands on the company’s initial four priority RAS(ON) targets. The company remains on track to nominate a first development candidate from this platform by the end of 2020.
• Preclinical Tumor Regressions Induced by First-in-Class KRAS^G12D(ON) Inhibitors – Data presented by the company at the RAS Targeted Drug Development conference demonstrated that the company’s first-in-class KRAS^G12D(ON) inhibitors induced significant decreases in tumor volume in a xenograft model of human pancreatic cancer driven by a KRAS^G12D mutation. The KRAS^G12D genotype is of particularly high clinical interest as there are currently no approved targeted therapies for the treatment of cancers driven by this mutation, which is found in approximately 35% of pancreatic cancers and 15% of colorectal cancers in the U.S.

Corporate Highlights

• Completed Follow-On Financing – The company completed a follow-on equity public offering in July 2020.  The upsized financing raised gross proceeds of $179.4 million before deducting underwriting discounts, commissions and other offering expenses payable by Revolution Medicines, further strengthening its balance sheet to support multiple clinical milestones and extend the company’s runway.

Third Quarter 2020 Financial Highlights

Cash Position: Cash, cash equivalents and marketable securities were $466.1 million as of September 30, 2020, compared to $122.8 million as of December 31, 2019. The increase was primarily due to proceeds from the company’s initial public offering in February 2020 and follow-on equity public offering in July 2020.

Revenue: Total revenue, consisting of revenue from the company’s collaboration agreement with Sanofi, was $12.7 million for the quarter ended September 30, 2020, compared to $12.5 million for the quarter ended September 30, 2019.

R&D Expenses: Research and development expenses were $34.9 million for the quarter ended September 30, 2020, compared to $23.0 million for the quarter ended September 30, 2019. This increase was primarily due to an increase in research expenses associated with the company’s pre-clinical research portfolio, and an increase in personnel-related expenses related to additional headcount.

G&A Expenses: General and administrative expenses were $5.3 million for the quarter ended September 30, 2020, compared to $3.1 million for the quarter ended September 30, 2019. This increase was primarily due to an increase in expenses associated with operating as a public company.

Net Loss: Net loss was $27.2 million for the quarter ended September 30, 2020, compared to net loss of $12.8 million for the quarter ended September 30, 2019.
