Secondary Outcome Measures:
  • Additional measures of Bowel movement (BM) frequency and symptoms, safety profile of the treatment regimens and any changes in pain intensity or opioid use.

Estimated Enrollment: 215
Study Start Date: October 2003

Inclusion criteria:

  • Subject is in any stage of cancer but has a minimum life expectancy of at least 3 months at the time of the Screening Visit.
  • Subject is taking opioid therapy for persistent cancer pain.
  • Subject meets the definition of opioid-induced bowel dysfunction as follows: Since starting opioid therapy, the subject has had decreased BM frequency and at least one of the following constipation symptoms [sensation of incomplete evacuation, difficulty in expelling stool (straining), hard stools (abnormal stool consistency)].
  • Subject understands the procedures, agrees to participate in the study, and has signed and dated the informed consent form prior to the initiation of any study-related activities, including discontinuation of pre-study laxative regimen or other prohibited medications.
  • Subject is able and willing to comply with a daily paper diary and is capable of completing paper questionnaires at study visits.

Exclusion criteria:

  • Subject is pregnant or lactating, or planning to become pregnant.

  • Subject is unable or unwilling to discontinue the use of and/or refrain from using laxatives of all types and formulation at the Screening Visit and throughout the entire study.
  • Subject has severe constipation that has not been appropriately managed such that the subject is at immediate risk of developing serious complications of constipation. This would include a subject who has reported no bowel movement for 7 consecutive days prior to the Screening Visit.
  • Subject with gastrointestinal or pelvic disorders known to affect bowel transit, produce gastrointestinal (GI) obstruction, or contribute to bowel dysfunction.
  • Subject is currently taking vinca alkyloids or plans to take vinca alkyloids during the study.
