Trial of Eflornithine Plus Sulindac in Patients With Familial Adenomatous Polyposis (FAP)
Phase: Phase 3
Diagnosis: Gastrointestinal Malignancies, Colorectal Cancer
NCT ID: NCT01483144
(View complete trial on ClinicalTrials.gov)
DFCI Protocol ID: 12-541
The purpose of this randomized, double-blind, Phase III trial is to determine if the combination of eflornithine plus sulindac is superior to sulindac or eflornithine as single agents in delaying time to the first occurrence of any FAP-related event. This includes: 1) FAP related disease progression indicating the need for excisional intervention involving the colon, rectum, pouch, duodenum and/or 2) clinically important events which includes progression to more advanced duodenal polyposis, cancer or death.

Stage 3: >25 polyps amenable to complete removal, or any incompletely removed
sessile polyp, or any evidence of high grade dysplasia, even if completely
removed. [Note: For staging purposes only.]
2. For all subjects, any rectal/pouch polyps > 5 mm must be excised at "baseline".
