Relay Therapeutics Reports Fourth Quarter and Full Year 2021 Financial Results and Corporate Highlights

Announced RLY-4008 interim clinical data that suggest it is the first investigational therapy that selectively binds to FGFR2 and avoids off-isoform toxicities in the treatment of patients with FGFR2-altered tumors Shared preclinical data for RLY-2608, the first known allosteric, pan-mutant and isoform-selective PI3Kα inhibitor and dosed the first patient in a first-in-human trial Continued to advance three additional oncology preclinical programs and two genetic disease preclinical programs, while expanding the capabilities of the Dynamo™ platform Raised $382 million in net proceeds from a follow-on financing in October 2021 $958 million in cash, cash equivalents and investments at end of 2021 expected to fund operations into at least 2025 CAMBRIDGE, Mass., Feb. 24, 2022 (GLOBE NEWSWIRE) — Relay Therapeutics, Inc. (Nasdaq: RLAY), a clinical-stage precision medicine company transforming the drug discovery process by combining leading-edge computational and experimental technologies, today reported fourth quarter and full year 2021 financial results and corporate highlights. “2021 was the year that Relay Therapeutics showed clinical data for the first time, with the RLY-4008 disclosure supporting our belief that our approach of integrating experimental techniques and computational power can make the discovery of medicines more efficient and effective,” said Sanjiv Patel, M.D., president and chief executive officer. “We also grew our team, continued to execute against our deep and broad precision medicine pipeline and pushed the boundaries of our Dynamo platform, through both internal innovation and the integration of an acquisition. We’ve entered 2022 with three clinical stage programs, a robust preclinical pipeline and a cash runway into at least 2025. We are excited to continue our efforts to achieve our goal of bringing life-changing therapies to patients.” 2021 Corporate Highlights RLY-4008 Presented preclinical data at the American Association for Cancer Research (AACR) Annual Meeting for RLY-4008, a highly selective irreversible and oral small molecule inhibitor of FGFR2Announced interim clinical data at the AACR-NCI-EORTC Molecular Targets Conference for RLY-4008 in a first-in-human trial in patients with FGFR2-altered cholangiocarcinoma, breast cancer and multiple other solid tumors The data suggest that RLY-4008 is the first investigational therapy designed to selectively bind to FGFR2 to avoid off-isoform toxicities for the treatment of patients with FGFR2-altered tumors, with study investigators reporting robust inhibition of FGFR2 in the first 49 subjects that was not shown to be limited by off-target toxicities, including hyperphosphatemia and diarrheaThe interim clinical data included results from FGFR2-altered solid tumors, with approximately 80% of all patients treated achieving reductions in tumor size at the cut-off date of September 9, 2021In pan-FGFRi treatment-naïve cholangiocarcinoma patients, RLY-4008 demonstrated tumor shrinkage in all six pan-FGFR treatment-naïve FGFR2 fusion positive cholangiocarcinoma patients, with three achieving confirmed partial responses, one of whom went on to surgery with curative intentRLY-4008 also demonstrated encouraging early activity in gene amplifications and mutations, such as the first reported objective response for an FGFR inhibitor in a patient with FGFR2-mutated breast cancer, based on publicly available information Initiated expansion cohorts at 70 mg once daily in December 2021In January 2022, the FDA granted orphan drug designation to RLY-4008 for the treatment of cholangiocarcinoma RLY-2608 Presented preclinical data at the AACR-NCI-EORTC Molecular Targets Conference and 2021 San Antonio Breast Cancer Symposium for RLY-2608, the first known allosteric, pan-mutant and isoform-selective PI3Kα inhibitor in a novel allosteric pocket The data help support the clinical development of RLY-2608 both in single agent and combination clinical trials for patients with PIK3CA (PI3Kα) mutant tumors, including PI3Kα-mutant, HR+/HER2- breast cancerThe data indicate RLY-2608 synergizes with fulvestrant and the CDK4/6 inhibitor abemaciclib in cell viability assays in PIK3CAmut/ER+/HER2- cell linesOral administration of RLY-2608 in combination with fulvestrant or abemaciclib led to improved efficacy compared to either agent alone in ER+/HER2- xenograft models representing the most commonly observed PIK3CA mutations in breast cancer (H1047R, E542K, E545K)The triple combination of all three agents resulted in deep regressions across all models, and additionally, the combination arms had similar tolerability to monotherapy arms Dosed the first patient in the dose escalation part of the RLY-2608 first-in-human trial in December 2021 Corporate Highlights Genentech initiated the cohort of RLY-1971/GDC-1971, an inhibitor of SHP2, in combination with GDC-6036, an inhibitor of KRAS G12C, in a Phase 1b trial in July 2021Extended leadership in integrating computational and experimental approaches, including by acquiring ZebiAI Therapeutics, Inc. and unlocking our ability to develop our machine learning powered DNA encoded library platform, REL-DEL (Relay DEL)Entered into a worldwide strategic collaboration with EQRx, Inc. to discover, develop and commercialize novel medicines against validated oncology targets, starting with one program and with the ability to mutually agree to add additional programs to the collaboration in the futureStrengthened the executive team with multiple new appointments leveraging the experienced senior leaders from within Relay Therapeutics and greatly expanded the team through the addition of approximately 100 employees 2022 Anticipated Milestones and Objectives Continue to enroll patients in the RLY-4008 expansion cohorts and provide a clinical data update in the second half of 2022Continue to enroll patients in the RLY-2608 first-in-human trial and gain experience in the clinic while also progressing against the rest of the preclinical PI3Kα mutant franchiseDisclose an additional target in the first half of this yearGenentech to continue driving the development and disclosures of RLY-1971/GDC-1971 in combination with GDC-6036 in the ongoing Phase 1b trial Fourth Quarter and Full Year 2021 Financial Results Cash, Cash Equivalents and Investments: As of December 31, 2021, cash, cash equivalents and investments totaled approximately $958.1 million, compared to $678.1 million as of December 31, 2020.
