Recursion Acquires Full Rights to REV102, a Potential First-in-Class Oral ENPP1 Inhibitor for Hypophosphatasia

Salt Lake City, UT, July 08, 2025 (GLOBE NEWSWIRE) -- Recursion (NASDAQ: RXRX) a leading clinical stage TechBio company decoding biology to radically improve lives today announced the acquisition of Rallybio鈥檚 (NASDAQ: RLYB) full interest in their joint ENPP1 inhibitor program (REV102) and an associated backup molecule for the treatment of hypophosphatasia (HPP), a rare and debilitating genetic disorder.

鈥淲e extend our sincere thanks to Rallybio for their invaluable partnership in advancing this program to its current stage,鈥� said David Hallett, Chief Scientific Officer of Recursion. 鈥淗aving full ownership of this important program allows Recursion to accelerate the development of the first potential oral disease-modifying treatment to HPP patients, who currently face significant challenges with limited access to existing therapies. While this is a preclinical asset that will require further study, we look forward to leveraging the full power of the Recursion OS to gain even deeper insights and accelerate delivery of the potential treatment.鈥�

鈥淭he Rallybio team has long been committed to targeting ENPP1 to address a significant unmet need in patients with HPP. By combining Rallybio鈥檚 expertise in HPP preclinical and translational research with Recursion鈥檚 integrated AI/experimental platform, we transformed this concept into the first potential oral disease-modifying treatment for HPP,鈥� said Stephen Uden, M.D., Chief Executive Officer of Rallybio. 鈥淲e look forward to the advancement of REV102 through key milestones and, ultimately, to the delivery of this important treatment to patients in need.鈥�

About REV102: ENPP1 Inhibitor Program for Hypophosphatasia (HPP)
The REV102 program targets ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1), an enzyme implicated in the pathogenesis of HPP. The mechanism of action involves a potent, highly selective inhibition of ENPP1, aiming to restore the crucial balance of inorganic pyrophosphate (PPi) necessary for proper bone mineralization, thereby addressing the underlying cause of HPP.

HPP is a devastating genetic disorder affecting over 7,800 diagnosed patients across the US and EU5, many of whom have limited access to current Enzyme Replacement Therapies (ERTs). Advancing REV102 presents a significant opportunity to not only provide a more accessible treatment but also to potentially reduce the substantial costs associated with long-term HPP management.

This candidate is designed to potentially be the first oral disease-modifying therapy for HPP, potentially offering an advantage in convenience and patient quality of life over injectable treatments. Furthermore, as a preliminarily non-immunogenic small molecule, this candidate could potentially offer a safer profile compared to biological ERTs, which can sometimes induce immune responses.

AI enabled Design and Development
The program originated from a joint venture with Rallybio, with Recursion leading the precision design of REV102. The Recursion OS 鈥� an integrated AI/experimental platform 鈥� was used to optimize for potency, selectivity, and PK/PD properties suitable for chronic dosing, enabling a candidate with potential best-in-class characteristics. Early preclinical data has demonstrated a favorable safety profile in animal models and validated ENPP1 as a druggable target in later-onset HPP. REV102 is currently in IND-enabling studies, with the initiation of Phase 1 clinical trials expected in the second half of 2026.

Terms of the Agreement
Under the terms of the agreement, Rallybio is eligible to receive certain payments, including $7.5 million in upfront equity, a contingent equity payment of $12.5 million upon the initiation of additional preclinical studies, and a $5 million milestone payment in connection with the initiation of dosing in a Phase 1 clinical study, as defined in the agreement. Rallybio is also eligible to receive low single-digit royalties on all future net sales by Recursion. In addition, Rallybio may be eligible to receive certain payments in the event of Recursion鈥檚 sale of the REV102 program.
