The purpose of this Phase III study is to see whether the product Kivia (Trademark) containing the active ingredient Zyactinase (Registered Trademark) can provide relief of IBS associated constipation and other symptoms of IBS. Subjects diagnosed with constipation dominant IBS will be randomised in a 1:1 ratio to receive either Kivia (Trademark) or matched placebo capsules for eight weeks Daily information about IBS-C symptoms will be captured by subjects using an electronic diary, and they will attend six clinic visits for efficacy and safety assessments.
