Inclusion criteria

* Must be receiving chronic, stable opioid therapy to treat non-malignant pain for at least 3 months prior to screening * Must have active OIC at screening * Active OIC must be confirmed during baseline screening bowel habit and symptom diary * Must be on stable diet

Exclusion criteria

* Has history of chronic therapy for chronic constipation prior to start of opioid therapy, or any potential non-opioid cause of bowel dysfunction that may be a major contributor to the constipation (i.e., mechanical obstruction or pseudo-obstruction) * Use of medications that might affect bowel movement frequency or constipation-related symptoms (e.g., prokinetics, anti-diarrheal agents, laxatives other than study-defined rescue laxative) * Has history of or current cancer (other than basal cell or squamous cell carcinoma of the skin) unless the malignancy has been in complete remission without maintenance chemotherapy for at least 5 years * Unstable thyroid disease

Design outcomes

Primary

MeasureTime frameDescription
Change from baseline in the number of spontaneous bowel movements during Week 4 of the 4-week treatment period4 WeeksCompare SP-333 (1, 3 & 6 mg) with placebo in the treatment of OIC as measured by the change from baseline in the number of spontaneous bowel movements during Week 4 of the 4-week treatment period

Secondary

MeasureTime frameDescription
To assess safety and tolerability of SP-333 in the treatment of non-malignant OIC4 weeksCompare the safety and tolerability of SP-333 (1, 3 & 6 mg) with placebo as measured by rates of adverse events, clinical laboratory abnormalities and significant changes in vital signs and ECGs.

Other

MeasureTime frameDescription
To evaluate stool consistency over the 4-week Treatment Period4 weeksCompare SP-333 (1, 3 & 6 mg) with placebo in rates of change from baseline in stool consistency over the 4 weeks of treatment.
To evaluate constipation-related symptoms over the 4-week Treatment Period4 weeksCompare SP-333 (1, 3 & 6 mg) with placebo in rates of change from baseline in constipation-related symptoms over the 4 weeks of treatment.
To evaluate bowel movement frequency responder rates [Complete Spontaneous Bowel Movements (CSBMs) and Spontaneous Bowel Movements (SBMs)] over the 4-week Treatment Period.4 weeksCompare SP-333 (1, 3 & 6 mg) with placebo in rates of change from baseline for bowel movement frequency responder rates \[Complete Spontaneous Bowel Movements (CSBMs) and Spontaneous Bowel Movements (SBMs)\] over the 4 weeks of treatment.
