Salt Lake City, UT, April 22, 2025 (GLOBE NEWSWIRE) — Recursion (NASDAQ: RXRX), a leading clinical stage TechBio company decoding biology to radically improve lives, will present preliminary data during the 2025 Digestive Disease Week (DDW) meeting from its ongoing Phase 1b/2 clinical trial, TUPELO, which is evaluating the safety and preliminary activity of REC-4881 for the treatment of familial adenomatous polyposis (FAP). The data will be presented as a late-breaking oral presentation during the Research Forum session on Hereditary GI cancer syndromes on Sunday, May 4, 2025 in San Diego.
“We are pleased that DDW has recognized the importance of our data in addressing the unmet needs of the FAP patient population, where no FDA-approved therapies currently exist,” said Najat Khan, PhD, Chief R&D Officer and Chief Commercial Officer at Recursion. “MEK 1/2 inhibition for the potential treatment of FAP was identified through our AI-powered Recursion OS platform, which analyzed cellular models of APC gene loss to uncover a potential first-in-disease treatment. We look forward to sharing our preliminary findings in our upcoming DDW presentation in May.”
Currently, there are no FDA-approved therapies for FAP, a rare hereditary autosomal dominant colorectal cancer predisposition syndrome, affecting approximately 50,000 people in the US, France, Germany, Italy, Spain, and the UK. REC-4881 has been granted Fast Track and Orphan Drug designation by the U.S. Food and Drug Administration as well as Orphan Drug designation by the European Commission.
REC-4881 is an orally bioavailable, non-ATP-competitive allosteric small molecule MEK 1/2 inhibitor. The platform analyzed cellular models of APC gene loss—the root cause of FAP—to identify compounds that suppress the disease-inducing effects of APC mutations.
In the late-breaking abstract, Recursion presented preliminary data as of February 7, 2025, showing that 13 patients received 4 mg of REC-4881 QD, with 84.6% experiencing at least one treatment-related adverse event (TRAE). The most commonly reported TRAE was rash / dermatitis acneiform, primarily Grade 1 or 2. Of the 5 efficacy-evaluable patients, they experienced a greater than 30% median reduction in total polyp burden after 12 weeks of treatment. The DDW data presentation will include new results from a later data cut-off, as well as the data included in the accepted abstract.

Presentation Title: Ongoing Phase 1b/2 Trial of the Allosteric MEK1/2 Inhibitor REC-4881 as Monotherapy in Familial Adenomatous Polyposis (FAP): Preliminary Safety and Efficacy Data
Session 0006, Presentation ID 354a: May 4, 2025 from 9:15 AM to 9:30 AM PDT
Presenter: N Jewel Samadder, M.D., Mayo Clinic Comprehensive Cancer Center
About the TUPELO Trial
The Phase 1b/2 TUPELO trial is evaluating REC-4881 as a potential treatment for patients with FAP post-colectomy/proctocolectomy. This multicenter, open-label study assesses the efficacy, safety, and pharmacokinetics of REC-4881 in this patient population.
About Digestive Disease Week
Digestive Disease Week® (DDW) is the largest international gathering of physicians, researchers and academics in the fields of gastroenterology, hepatology, endoscopy and gastrointestinal surgery. Jointly sponsored by the American Association for the Study of Liver Diseases (AASLD), the American Gastroenterological Association (AGA), the American Society for Gastrointestinal Endoscopy (ASGE) and the Society for Surgery of the Alimentary Tract (SSAT), DDW is an in-person and online meeting from May 3-6, 2025. The meeting showcases nearly 6,000 abstracts and over 1,000 invited talks on the latest advances in GI research, medicine and technology. More information can be found at www.ddw.org.
