Recursion 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: >12 years of age and weighing at least 40 kg; Progressive meningioma that is amenablto volumetric c analysis; 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 e currently no FDA-approved drugs for the treatment of patients with NF2, an inheritedenetic syndromome 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. 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.
