Detaljeret beskrivelse

This is a multicenter, double-blind, placebo-controlled, parallel-group study in participants with OIC taking opioid therapy for chronic non-cancer pain. Approximately 600 participants (300 participants per treatment group) with OIC will be randomized at approximately 75 study centers to receive either oral 0.25 mg CB-5945 BID or oral matching placebo BID for the 12-week double-blind treatment period, followed by a 4-week follow-up period. All randomized participants will be evaluated for clinical response for duration of their study participation. All participants will be followed for safety for 4 weeks after last dose of the study medication, regardless of when they discontinue study medication. The clinical study report for this study includes pooled results for studies 5945-OIC-12-02 (NCT01901302) 5945-OIC-12-03 (NCT01901328), and 5945-OIC-12-04 (NCT01901341).

Beskrivelse

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)

Foranstaltningsbeskrivelse
Tidsramme
Overall Spontaneous Bowel Movement (SBM) Responder Rates at 12 Weeks
Tidsramme: 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).

Tidsramme: Baseline, 12 uger
CORGISS er designet til at vurdere GI-symptomer relateret til opioidbrug hos patienter med kroniske ikke-kræftsmerter. CORGISS beder deltagerne om at vurdere sværhedsgraden af ​​GI-symptomer i løbet af de foregående 24 timer, med svar fra 0 ("oplevede ikke") til 4 ("meget alvorlig").
