描述
Key Inclusion Criteria:
- Is taking a stable daily dose of opioids of ≥30 mg morphine equivalent total daily dose (METDD) for chronic non-cancer pain
- Has constipation that is caused by the chronic use of opioids
- Is willing to use only the study provided laxative(s) and to discontinue use of all other laxatives, enemas, stool softeners, and other medications to treat constipation (e.g., lubiprostone) from Screening until the last study assessment
Key Exclusion Criteria:
- Has gastrointestinal (GI) or pelvic disorders known to affect bowel transit (for example [e.g.], obstruction) or contribute to bowel dysfunction
- Has evidence of intestinal obstruction
- Has a history of rectal bleeding not due to hemorrhoids or fissures within 6 months of screening
- Has an active malignancy of any type (participants with a history of successfully treated malignancy >5 years before the scheduled administration of study medication and participants with treated basal or squamous cell cancer may be enrolled)
- Is taking antispasmodics (e.g., dicyclomine), antidiarrheals (e.g., loperamide), prokinetics (e.g., metoclopramide), or locally acting chloride channel activators (e.g., lubiprostone)
- Is taking non-opioid medications known to cause constipation (e.g., iron sulfate therapy, tricyclic antidepressants)

Overall Spontaneous Bowel Movement (SBM) Responder Rates at 12 Weeks
大体时间:12 weeks
|
A Spontaneous Bowel Movement (SBM) Weekly Responder (calculated for each week of the 12-week double-blind treatment period) is a participant who has ≥ 3 SBMs for the week and an increase from baseline of ≥1 SBM for the specified week, based on at least 4 Available Data Days (ADDs) during the week. A Complete SBM (CSBM) Weekly Responder is a participant who has ≥ 3 CSBMs for the specified week and an increase from baseline of ≥1 CSBM for the week. For the definition of the primary efficacy endpoint, Overall SBM Responder is a participant who is a Weekly SBM Responder for 9 of the 12 weeks of the double-blind treatment period, including 3 of the last 4 weeks (Weeks 9, 10, 11 and 12). |

CORGISS 旨在评估与慢性非癌症疼痛患者使用阿片类药物相关的胃肠道症状。
CORGISS 要求参与者对过去 24 小时内胃肠道症状的严重程度进行评分,答案范围从 0(“没有经历过”)到 4(“非常严重”)。

A CSBM Weekly Responder is a participant who has ≥ 3 CSBMs for the specified week and an increase from baseline of ≥1 CSBM for the week.
An Overall CSBM Responder is a subject who is a Weekly CSBM Responder for 9 of the 12 weeks of the double-blind treatment period, including 3 of the last 4 weeks (Weeks 9, 10, 11 and 12).
