Study SP304-20210: A Randomized, 12-Week, Double-Blind, Placebo-Controlled, Repeat-Dose, Oral, Dose-Ranging Study to Assess the Safety and Efficacy of Plecanatide in Patients With Chronic Idiopathic Constipation

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).

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.

Inclusion Criteria:

- Male or female aged 18-75, inclusive

- Body Mass Index = 18-35 kg/m2, inclusive

- Meets modified Rome III criteria for functional chronic idiopathic constipation for at
least 3 months with symptom onset for at least 6 months. Note: For this trial,

constipation during the screening, pre-treatment, treatment and 2-week post-treatment

- Patients with hemorrhoids and/or diverticulosis (NOT diverticulitis) CAN be entered
