Arginase-1 (ARG1) is an enzyme that converts the amino acid arginine into urea and ornithine. ARG1 is mainly expressed in hepatocytes but different myeloid cells are also capable of ARG1-expression.
An ARG1-induced arginine depletion suppresses T cell function through the impairment of the T cell

PRIMARY OBJECTIVES:
I. To determine the relative efficacy of celecoxib plus eflornithine (DFMO) versus celecoxib plus DFMO placebo in participants with familial adenomatous polyposis (FAP), as evidenced by the percent change from baseline in the number of polyps in focal area(s) of the colorectum in
