Initiated global clinical trial collaboration with Pfizer for combination development of RLY-2608 + fulvestrant + atirmociclib (CDK4i) in PI3Kα-mutated HR+/HER2- metastatic breast cancer, with clinical start planned by end of 2024

Approximately $688 million in cash, cash equivalents and investments at end of Q2 2024, expected to fund operations into second half of 2026

CAMBRIDGE, Mass., Aug. 06, 2024 (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 second quarter 2024 financial results and corporate highlights.

“In the second quarter, we made important progress continuing to advance our clinical programs, which we believe has positioned us well for multiple data readouts later this year. Additionally, we look forward to expanding the RLY-2608 development program, with the initiation of a new triplet combination with Pfizer's novel investigative selective-CDK4 inhibitor atirmociclib by the end of the year,” said Sanjiv Patel, M.D., President and Chief Executive Officer of Relay Therapeutics. “Looking further ahead, we are very excited by the pre-clinical programs we unveiled in June, including our first two genetic disease programs, which will be important in driving our continued growth and diversification.”

Recent Corporate Highlights

RLY-2608 (ReDiscover study)

• RLY-2608 doublet: continued to enroll patients with PI3Kα-mutant, HR+, HER2- locally advanced or metastatic breast cancer in dose expansion cohorts of RLY-2608 400mg BID and 600mg BID in combination with fulvestrant
  • The next data update is expected in the fourth quarter of 2024 and will include approximately 100 patients across doses in the safety database and approximately 60 patients at the 600mg BID dose, including about 40 who have had the opportunity to be on RLY-2608 for at least 6 months
• RLY-2608 triplet:
  • CDK4/6: continued enrollment of RLY-2608 + fulvestrant + ribociclib triplet combination in patients with PI3Kα-mutant, HR+, HER2- locally advanced or metastatic breast cancer
  • CDK4: announced a clinical trial collaboration to evaluate atirmociclib, Pfizer’s investigative selective-CDK4 inhibitor, in combination with RLY-2608 and fulvestrant in patients with PI3Kα-mutant, HR+, HER2- metastatic breast cancer. The RLY-2608 + atirmociclib + fulvestrant triplet combination is planned to begin by the end of 2024
• RLY-2608 monotherapy: continued to enroll patients with unresectable or metastatic solid tumors with a PI3Kα mutation in dose escalation portion of RLY-2608 monotherapy arm and reported partial responses in multiple tumor types

Migoprotafib (GDC-1971)​

• As previously disclosed, Genentech has terminated the collaboration agreement for the development and commercialization of migoprotafib
• The company will not continue development of migoprotafib

Pre-Clinical Programs

• Disclosed three new pre-clinical programs: vascular malformations, Fabry disease and NRAS
• Vascular Malformations
  • PI3Kα is the most common driver mutation among specific types of vascular malformations, which are a series of rare syndromes that occur due to atypical development of lymphatic and/or blood vessels and can become life-threatening, depending on what vessel(s) are involved
  • In the U.S., an estimated 170,000 people have one of the sub-types driven by a PI3Kα mutation, which include PIK3CA-related overgrowth spectrum, lymphatic malformations, venous malformations and cerebral cavernous malformations
  • A mutant selective PI3Kα inhibitor provides the opportunity for greater target coverage, leading to the potential for improved efficacy and better chronic tolerability
  • Relay Therapeutics plans to initiate clinical development of RLY-2608 in vascular malformations in the first quarter of 2025
• Fabry Disease
  • In Fabry disease, harmful levels of Gb3 accumulate in blood cells and tissues throughout the body, due to insufficient αGal enzyme activity, which can lead to a range of symptoms, including potentially life-threatening ones such as kidney failure, heart failure and stroke. In the U.S., approximately 8,000 people have Fabry disease
  • Relay Therapeutics has created the first investigational non-inhibitory chaperone for Fabry disease, which is designed to stabilize the αGal protein without inhibiting its activity, thus enabling greater Gb3 clearance across organs
  • The company expects its non-inhibitory chaperone to enter the clinic in the second half of 2025
• NRAS
  • In the U.S., an estimated 28,000 people are diagnosed annually with mutated NRAS solid tumors, which are a known oncogene driver in the RAS family and can lead to a number of cancers, including melanoma, colorectal and non-small-cell lung
  • Relay Therapeutics has created the first NRAS-selective inhibitor, which has been designed to address the liabilities of current pan-RAS inhibitors by only binding to NRAS, while sparing KRAS and HRAS
  • The company expects to initiate clinical development of its NRAS-selective inhibitor in the second half of 2025

Anticipated Upcoming Milestones

• Breast Cancer
  • RLY-2608 + fulvestrant data update in the fourth quarter of 2024
  • RLY-2608 + fulvestrant + ribociclib initial safety data in the fourth quarter of 2024
  • RLY-2608 + fulvestrant + atirmociclib clinical trial initiation by the end of 2024
  • RLY-2608 + fulvestrant potential Phase 3 trial initiation in 2025
• Lirafugratinib: tumor agnostic data and regulatory update in the second half of 2024
• Pre-clinical
  • Vascular malformations: RLY-2608 clinical trial initiation in the first quarter of 2025
  • Fabry disease: clinical start in the second half of 2025
  • NRAS: clinical start in the second half of 2025

Second Quarter 2024 Financial Results

Cash, Cash Equivalents and Investments: As of June 30, 2024, cash, cash equivalents and investments totaled $688.4 million compared to $750.1 million as of December 31, 2023. The company expects its current cash, cash equivalents and investments will be sufficient to fund its current operating plan into the second half of 2026.

R&D Expenses: Research and development expenses were $92.0 million for the second quarter of 2024, as compared to $88.2 million for the second quarter of 2023. The increase was primarily due to additional external costs in connection with the ReDiscover trial for RLY-2608.

G&A Expenses: General and administrative expenses were $20.1 million for the second quarter of 2024, as well as for the second quarter of 2023.

Net Loss: Net loss was $92.2 million for the second quarter of 2024, or a net loss per share of $0.69, as compared to a net loss of $98.5 million for the second quarter of 2023, or a net loss per share of $0.81.
