Brief Summary:
This is a randomized, double-blind, placebo controlled, 12 week repeat oral dose, dose ranging study to determine the efficacy and safety of 3 doses of plecanatide compared to placebo in patients with Chronic Idiopathic Constipation (CIC).

Condition or disease Intervention/treatment Phase
Chronic Idiopathic Constipation Drug: plecanatide Other: Placebo Phase 2 Phase 3

Detailed Description:
This is a Phase IIb/III, randomized, double-blind, placebo-controlled, 12-Week, Repeat, Oral Dose Ranging, study to determine the safety and efficacy of plecanatide in patients with chronic idiopathic constipation (CIC). Subjects diagnosed with CIC via modified Rome III criteria will be screened against the inclusion and exclusion criteria for the study and enter a 2 Week pre treatment screening. During this phase patients will be required to call in their bowel movements (BM diary) as they occur, and call at least once daily to complete a patient diary of questions on their symptoms (Symptom Diary) associated with CC, as they will throughout the trial. Patients who complete at least 5 days of dosing per week, 6 of each 7 day period of BM diary calls, and continue to have less than 3 complete spontaneous movements per week (as well as meeting other inclusion and exclusion criteria) will be enrolled and randomized to one of three plecanatide doses 0.3 mg, 1.0 mg, and 3.0 mg or placebo. 880 patients will be randomized with the intent of having 200 patients per treatment group (each group the same size) included in efficacy analyses. All subjects receiving at least one dose of plecanatide or matching placebo will be included in the safety analyses.

Primary Outcome Measures :
  1. Overall Responder 9/12 Weeks [ Time Frame: 12 weeks ]
    A complete spontaneous bowel movement (CSBM) occurs at least 24 hours after laxative use and the patient reports a feeling of complete evacuation. A weekly responder will have 3 or more CSBMs and an increase of at least one CSBM from baseline. An overall responder is a patient who is a weekly responder for at least 9 of the 12 treatment weeks, including at least 3 of the last 4 weeks.

Secondary Outcome Measures :
  1. Reduction in Straining and Abdominal Symptoms Such as Pain, Discomfort and Bloating. [ Time Frame: 12 Weeks ]
    To demonstrate a reduction in straining and abdominal symptoms such as pain, discomfort and bloating as determined by patient reported outcome (PRO) measures collected via an Interactive Voice Response System (IVRS). To demonstrate an improvement in the hardness of stool, the frequency of spontaneous bowel movements, and a reduction in time to first bowel movement. To monitor and report all treatment emergent adverse events.
