This phase 3, 12-week, randomized, double-blind, placebo-controlled, multi-center study will evaluate the safety and efficacy of tenapanor in subjects with constipation-predominant irritable bowel syndrome (IBS-C) as defined by the ROME III criteria and who have active disease as determined after a two-week screening period. Subjects who qualify and are randomized into the study will either receive 50mg BID of tenapanor or placebo BID for 12 week treatment period and then undergo a 4 week placebo controlled randomized withdrawal.

During the 12-week treatment period, subjects will record daily assessments including: frequency and timing of bowel movements; sensation and complete bowel emptying; consistency of bowel movements; degree of straining, worst abdominal pain, abdominal discomfort, abdominal bloating, abdominal fullness and abdominal cramping. Subjects will also record weekly assessments including: adequate relief of IBS severity, and constipation severity.
At the end of the 12-week treatment period, there will be a 4-week randomized withdrawal period in which subjects who complete the study in Tenapanor group will be randomized to either Tenapanor 50mg BID or placebo BID (1:1) and subjects who complete the study in the placebo group will be assigned to receive Tenapanor 50mg BID.
