Recursion Announces FDA Clearance of Investigational New Drug Application for REC-1245, a Potential First-In-Class RBM39 Degrader for Biomarker-Enriched Solid Tumors and Lymphoma

• First program to combine Recursion's end-to-end suite of AI-enabled active learning modules, resulting in target identification to IND enabling studies in under 18 months
• Plan to initiate dosing of Phase 1/2 in Q4 2024 to evaluate REC-1245 in a biomarker enriched patient population, including patients with solid tumors and lymphoma

SALT LAKE CITY, Oct. 02, 2024 (GLOBE NEWSWIRE) - Recursion (NASDAQ: RXRX), a leading clinical stage TechBio company decoding biology to industrialize drug discovery, today announced that the U.S. Food and Drug Administration (FDA) has cleared an investigational new drug (IND) application for a Phase 1/2 clinical trial of REC-1245, a new chemical entity for the treatment of biomarker-enriched solid tumors and lymphoma.

Chris Gibson, Ph.D., Co-founder and CEO of Recursion said, “REC-1245 is a prime example of using an expansive AI-enabled platform for drug discovery. After exploring many predicted biological and chemical relationships across our maps of biology, we identified RMB39 as a novel target that looks functionally similar to the well-known but hard to drug target CDK12. We also identified and optimized small molecules that target RBM39 without directly impacting CDK12 or CDK13 using these same AI-enabled maps. In under 18 months, leveraging some of our newer chemistry tools, Recursion rapidly progressed REC-1245 from novel target biology to preclinical drug candidate, more than twice the speed of industry average.”

Recursion identified the novel regulatory role of RBM39 associated with CDK12 using its maps of biology and first reported this relationship in early 2023 at Download Day, Recursion's R&D and investor event. Recursion believes the modulation of RBM39 may be associated with a therapeutic effect in certain biomarker-enriched solid tumors and lymphoma. Additionally, Recursion estimates that the initially addressable population for this potential therapeutic to be >100,000 patients in the US and EU5. REC-1245 is a potent and selective RBM39 degrader with a potential first-in-class profile. Preclinical data support that RBM39 degradation induces splicing defects which downregulate DNA Damage Response (DDR) networks and cell cycle checkpoints.

“RBM39 degraders may offer a promising therapeutic approach for patients with solid tumors, particularly those with limited treatment options,” said Najat Khan, Ph.D., Chief R&D Officer and Chief Commercial Officer at Recursion. “Recursion's platform was among the first to rapidly uncover the therapeutic potential of RBM39 degradation, a finding now validated by independent research. This mechanism provides new opportunities for targeting tumors, which are often resistant to conventional treatments. By advancing this research, we aim to deliver a critical option for patients facing significant unmet needs, ultimately improving their prognosis and quality of life.”

The Phase 1/2 clinical trial will evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and potential monotherapy efficacy of REC-1245, and is expected to initiate in Q4 2024.
