* Chronic faecal incontinence

* Subjects with a history of neoplastic disease within 5 years (except for basal cell carcinoma or non-metastatic squamous cell carcinoma of the skin)
* Subjects taking opioids for the management of drug addiction Subjects who do not meet any of the following criteria regarding baseline medications. Analgesia (including opioids and NSAIDs) should be stable throughout the trial.
* Any baseline analgesia must have been administered at a stable dose for a minimum of 4 weeks. If non-opioid analgesia recently discontinued, must have stopped at least 4 weeks prior to baseline
* Laxatives (outside that allowed by the protocol) are not permitted; these agents must have been discontinued at the screening visit.
* Use of drugs known to affect gut transit time (other than opioids) are not permitted (see Section 6.9 for exceptions)
* Use of mixed agonist/antagonist, or partial agonist opioids are not permitted (e.g. buprenorphine, pentazocine, cyclazocine, nalbuphine, nalorphine)
* Experimental agents must have been discontinued at least 8 weeks prior to screening, or for a period equivalent to 5 half-lives (t½) of the agent (whichever is longer)
* Subjects with a history of clinically significant and/or persistent disorder that, in the investigators opinion, may affect the clinical trial assessments
* Subjects with any laboratory tests considered clinically significant at screening.
* Subjects not ambulatory i.e. bedridden or require use of a commode
