Reported interim RLY-2608 data demonstrating 9.2-month median PFS in heavily pre-treated patients with PI3Kα-mutated, HR+/HER2- metastatic breast cancer at RP2D

Plan to initiate 2L pivotal trial of RLY-2608 + fulvestrant in 2025

Approximately $840 million in cash, cash equivalents and investments at end of Q3 2024, expected to fund operations into second half of 2027

CAMBRIDGE, Mass., Nov. 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 third quarter 2024 financial results and recent corporate highlights.

“In the third quarter, we reported very encouraging interim data showing that RLY-2608 + fulvestrant led to clinically meaningful progression free survival in heavily pre-treated patients with PI3Kα-mutated, HR+, HER2- metastatic breast cancer,” said Sanjiv Patel, M.D., President and Chief Executive Officer of Relay Therapeutics. “Based on these data, we are preparing to initiate a pivotal trial in 2L breast cancer in 2025, which we expect to be able to fully fund through top-line readout with our existing cash on hand. We also continue to progress our pre-clinical programs and look forward to bringing new programs into the clinic in 2025.”

Recent Corporate Highlights

RLY-2608 (ReDiscover study)

• RLY-2608 doublet:
  • Reported interim data for RLY-2608 + fulvestrant in patients with PI3Kα-mutated, HR+, HER2- metastatic breast cancer who had previously received at least one prior CDK4/6 inhibitor. The data demonstrated clinically meaningful progression free survival (PFS) at the company’s recommended Phase 2 dose (RP2D) of 600mg BID. The cut-off date for these data was August 12, 2024. Key highlights included:
    • 9.2-month median PFS across all mutations & 10.3 months among patients with kinase mutations
    • 33% objective response rate (ORR) across all patients & 53% ORR in patients with kinase mutations at the RP2D
    • Favorable overall tolerability profile; at RP2D, only two patients discontinued treatment due to adverse events & only 1 patient experienced Grade 3 hyperglycemia
      
    • RLY-2608 + fulvestrant data will be presented at the San Antonio Breast Cancer Symposium, taking place December 10-13, 2024. Details of the poster spotlight presentation are as follows:
      
      
      • Abstract Title: PS7-01: Efficacy of RLY-2608, a mutant-selective PI3Kα inhibitor in patients with PIK3CA-mutant HR+HER2- advanced breast cancer: ReDiscover trial
      • Abstract Number: SESS-2211
      • Session: Concurrent Poster Spotlight Session 7: Targeting the ER and PI3K pathway: Novel drugs and combinations
      • Date/Time: Wednesday, December 11, 8:00-9:30 a.m. ET (7:00-8:30 a.m. CT)
  • Data support planned initiation of Phase 3 pivotal trial for RLY-2608 + fulvestrant in 2025
• RLY-2608 triplet: Continued to progress two potential front-line triplet regimens in patients with PI3Kα-mutated, HR+, HER2- metastatic breast cancer who had previously received at least one prior CDK4/6 inhibitor, including:
  • CDK4/6: RLY-2608 + ribociclib + fulvestrant dose escalation is currently testing biologically active doses of RLY-2608 and is on track to identify a dose of RLY-2608 that is combinable with full-dose ribociclib. Expansion cohorts are expected to initiate in the first half of 2025
  • CDK4: RLY-2608 + atirmociclib + fulvestrant trial on track to initiate by the end of 2024
    

Lirafugratinib (RLY-4008)

• Presented updated FGFR2 fusion tumor agnostic data at the AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics, October 23-25, 2024
• Provided regulatory update regarding lirafugratinib regulatory path in which the FDA suggested that the company first file a new drug application (NDA) in cholangiocarcinoma, followed by a tumor agnostic supplemental NDA for FGFR2 fusions with data from more patients and more follow up
• Disclosed plans to seek a global commercialization partner for lirafugratinib in order to maintain company’s focus on the remainder of the portfolio
  

Corporate Highlights

• Raised $230 million of gross proceeds in an underwritten follow-on public offering in September 2024
• Completed series of changes to streamline the research organization, collectively resulting in an expected $50 million in annual savings and workforce reduction of approximately 15%. Changes are part of the company’s shift to becoming more development-focused in preparation for the upcoming RLY-2608 pivotal trial as well as new programs entering the clinic over the course of 2025

Anticipated Upcoming Milestones

• Breast Cancer
  • 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 + ribociclib dose expansion initiation in the first half of 2025
  • RLY-2608 + fulvestrant 2L Phase 3 trial initiation in 2025
• Pre-clinical
  • Vascular malformations: RLY-2608 clinical trial initiation in the first quarter of 2025

  • NRAS: clinical start in the second half of 2025
    

Third Quarter 2024 Financial Results

Cash, Cash Equivalents and Investments: As of September 30, 2024, cash, cash equivalents and investments totaled $839.6 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 2027.

Revenue: Revenue was $0 for the third quarter of 2024, as compared to $25.2 million for the third quarter of 2023. The decrease was primarily due to the recognition of previously received milestone payments under the company’s Collaboration and License Agreement with Genentech, Inc. during the third quarter of 2023.

R&D Expenses: Research and development expenses were $76.6 million for the third quarter of 2024, as compared to $81.5 million for the third quarter of 2023. The decrease was primarily due to the impact of prioritization of certain programs in the company’s pipeline, as previously disclosed in 2023 and earlier in 2024.

G&A Expenses: General and administrative expenses were $19.8 million for the third quarter of 2024, as compared to $18.5 million for the third quarter of 2023. The increase was primarily due to an increase in stock compensation expense, partially offset by decreases in other employee compensation costs and certain other general and administrative expenses.

Net Loss: Net loss was $88.1 million for the third quarter of 2024, or a net loss per share of $0.63, as compared to a net loss of $65.7 million for the third quarter of 2023, or a net loss per share of $0.54.
