New drug eRapa could slow polyps in inherited colon cancer condition
NCT ID NCT06950385
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests if the drug eRapa can slow disease progression in adults with Familial Adenomatous Polyposis (FAP), a condition that causes many polyps in the gut and raises cancer risk. About 168 participants will take eRapa or a placebo daily every other week. Researchers will track how long it takes for the disease to worsen, using colonoscopies and other checks every 3 to 6 months.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Participant must be ≥18 years of age inclusive. 2. Participant must have documented FAP, confirmed by adenomatous polyposis coli genotype mutation testing. 3. Participant must have at least 1 of the following high-risk features: \>100 polyps but ≤500 polyps in the colon, or ≥10 polyps in the retained rectum/sigmoid or ileal pouch (≥3 mm in size), or Spigelman stage 3 or 4 with at least 1 polyp ≥10 mm to be removed at baseline or on endoscopy performed within 18 months of screening. 4. Contraceptive use by participants or participant partners until at at least 12 weeks after stopping study treatment. 5. Agree not to donate gametes for the purpose of reproduction until at at least 12 weeks after stopping study treatment. 6. Willing to undergo endoscopic evaluation. Exclusion Criteria: 1. Participant has unresected or incompletely resected high-grade dysplasia or cancer within the duodenum, colon, rectum, or ileal pouch at screening endoscopy. 2. Participant has any polyps ≥8 mm in the duodenum, colon, rectum, or ileal pouch remaining after screening endoscopy (polyps ≥8 mm are to be resected during screening endoscopy). 3. Participant has had surgery within 6 weeks of the trial. 4. Participant has active malignancy or history of malignancy diagnosed within 24 months of first dose of trial intervention. 5. Participant has a history of, or currently has, an acquired or primary (congenital) immunodeficiency. 6. Participant has active and clinically significant tuberculosis (positive Quantiferon Gold test), bacterial, fungal, or viral infection, including human immunodeficiency virus (HIV). 7. Participant has any medical or social condition that, in the opinion of the Investigator, might increase participant risk if enrolled, prevent participant compliance to trial procedures, or present an unacceptable confound to safety or clinical trial data.
