• If successful, REC-2282 could be the first approved treatment for NF2-mutated meningiomas, which are debilitating lesions that occur in approximately 33,000 patients per year
• REC-2282 has been granted Fast Track and Orphan Drug designations for NF2 meningiomas by the U.S. Food and Drug Administration, as well as Orphan Drug designation for NF2 meningiomas by the European Commission

Recursion (NASDAQ: RXRX), the clinical-stage biotechnology company industrializing drug discovery by decoding biology, today announced the initiation of its Phase 2/3 POPLAR-NF2 clinical trial during the Children's Tumor Foundation NF Conference. The trial will evaluate REC-2282: a potentially first-in-disease, orally bioavailable, central nervous system (CNS) penetrant small molecule histone deacetylase (HDAC) inhibitor, for the treatment of progressive neurofibromatosis type 2 (NF2)-mutated meningiomas.

The study is actively enrolling patients who meet criteria including the following:

1. >12 years of age and weighing at least 40 kg
2. Progressive meningioma that is amenable to volumetric analysis
3. Has either 1) sporadic meningioma with confirmed NF2 mutation; or, 2) confirmed diagnosis of NF2 disease (revised Manchester criteria); or, 3) at least one NF2-related tumor (with pathogenic germline or proven mosaic NF2 variant)

There are currently no FDA-approved drugs for the treatment of patients with NF2, an inherited genetic syndrome that can cause a variety of benign tumors in the central nervous system, including meningiomas. Recursion discovered REC-2282 as a potential candidate for treatment of disease resulting from mutation in the NF2 gene by leveraging its proprietary AI-powered drug discovery platform, the Recursion OS. We believe this approach, in which machine learning is used to identify relationships between biological contexts and chemical entities, will enable Recursion to accelerate the drug discovery process and expand the scope of potential therapeutic candidates for numerous diseases.

"We are currently crying out for a therapy for inoperable meningiomas and in particular the multiple meningiomas that we see in neurofibromatosis type 2 that cause so much morbidity and ultimately mortality," said Professor Gareth Evans, Manchester University NHS Foundation Trust, St. Mary's Hospital. "An efficacious drug that reduces meningioma size or at least stabilizes tumor growth would be highly impactful for neurofibromatosis type 2 patients, with 60% of even isolated meningiomas in these patients being associated with loss of NF2 gene function."

"Initiating patient enrollment in our Phase 2/3 POPLAR-NF2 clinical trial marks a significant moment for patients with neurofibromatosis type 2 and sporadic meningiomas driven by mutations in the NF2 gene," said Glenn Morrison, M.Sc., Ph.D., Vice President of Clinical Development at Recursion.

The Phase 2/3 trial is designed as a randomized, multi-center, double-blind, placebo-controlled study to investigate the safety, efficacy and pharmacokinetics of REC-2282. The study is expected to enroll approximately 90 participants.

About REC-2282
REC-2282 is a CNS-penetrant, orally bioavailable, small molecule pan-HDAC inhibitor being developed for the treatment of NF2-mutated meningiomas. This molecule appears to be well tolerated, including in patients dosed for multiple years, and potentially has reduced cardiac toxicity that would differentiate it from other HDAC inhibitors. Its oral bioavailability and CNS penetrance distinguish it from currently-approved HDAC inhibitors. REC-2282 has been granted Fast Track and Orphan Drug designations for NF2-mutated meningiomas by the U.S. Food and Drug Administration, as well as Orphan Drug designation for NF2-mutated meningiomas by the European Commission.

About Neurofibromatosis Type 2
NF2 is an autosomal dominant, inherited, rare tumor syndrome caused by loss-of-function mutations in the NF2 tumor suppressor gene, which encodes the cell signaling regulator protein 'merlin.' Loss of NF2 function results in growth of the hallmark tumors that characterize this disease: vestibular schwannomas (VS) and meningiomas. The VS and meningioma tumor types seen in NF2 are among the most common in neuro-oncology. In addition, NF2 mutations give rise to mesotheliomas and underlie subsets of additional tumor types. NF2-mutated meningiomas occur in approximately 33,000 patients per year. The large numbers of these lesions that frequently occur in NF2 patients lead to significant morbidity, including hearing, vision, and mobility impairment, and mortality.
