Summary:

      This clinical study is designed as a multiple-ascending-dose, safety and tolerability study
      with IW-3300. The study drug will be administered as a low-volume [20 mL] enema. Study
      participants will be randomized in a 2:1 ratio to receive IW-3300 or placebo. Up to 3
      different doses of IW-3300 will be studied. Safety reviews will be conducted before
      proceeding to each higher dose.
