Detailed Description
This is a Phase 1b/2, trial to evaluate efficacy, safety, pharmacokinetics and pharmacodynamics of REC-4881 in participants with Familial Adenomatous Polyposis (FAP). This two-part study will treat participants with phenotypic classical FAP with disease involvement of the duodenum or the residual colon/rectum/pouch as the primary disease site. Part 1 of the study enrolled seven participants with FAP who are post-colectomy/proctocolectomy. Participants were randomized to Placebo or REC-4881. Part 2 of the study will treat participants with escalating dose levels of REC-4881 during the Dose Finding. Participates in Cohort Expansion will be treated with a dose(s) to determine the RP2D.
