Drug: BI 201335
Registration Number
NCT01637922
Lead Sponsor
Boehringer Ingelheim
Brief Summary

Otherwise healthy subjects who are currently bein maintained on either methadone or buprenorphine/naloxone for opioid maintenance therapy who have been on a stable dose for at least 30 days will be administered BI 201335 daily to determine if a drug interaction occurs between BI 201335 and either methadone or buprenorphine/naloxone.

Secondary Outcome Measures
NameTimeMethod
Pharmacodynamic Assessment of Withdrawal From Either Methadone or Buprenorphine/Naloxone Using the Objective Opiate Withdrawal Scale (OOWS)-Change From BaselineBaseline, Day 2, Day 3, Day 4, Day 5, Day 6, Day 7, Day 8, Day 9, Day 10, Day 11, Day 12 and End of treatment

The OOWS is conducted by a trained independent examiner for either the presence or absence of the following symptoms during a 10 minute observation period at designated times during the trial. The minimum possible OOWS score is 0 and the maximum possible score is 13. Objective criteria: Yawning, Rhinorrhoea, Piloerection, perspiration, lacrimation, mydriasis, hot and cold flushes, restlessness, vomiting, tremors, anxiety, muscle twitches, abdominal cramps. Higher score indicates increasing severity of opiate withdrawal syndrome.

Pharmacodynamic Assessment of Withdrawal From Either Methadone or Buprenorphine/Naloxone Using the Subjective Opiate Withdrawal Scale (SOWS)-Change From BaselineBaseline, Day 2, Day 3, Day 4, Day 5, Day 6, Day 7, Day 8, Day 9, Day 10, Day 11, Day 12 and End of treatment

The SOWS is a subjective scale self-evaluated by the subject. The SOWS shows items reflecting the common motor, autonomic, gastrointestinal, musculo-skeletal, and psychic symptoms of opiate withdrawal. Subjects are instructed to rate each symptom on a scale of 0 to 4 (0=not at all, 1=a little, 2=moderately, 3=quite a bit, 4=extremely) at designated times \[c.f. Section 3.1\]. The minimum possible SOWS score is 0, the maximum 64. The following subjective criteria are answered by the subject using the scale below: 1) I feel anxious, 2) I feel like yawning 3) I am perspiring, 4) My eyes are watering, 5) My nose is running, 6) I have goose flesh, 7) I am shaking 8) I have hot flushes, 9) I have cold flushes, 10) My bones and muscles ache, 11) I feel restless, 12) I feel nauseous, 13) I feel like vomiting, 14) My muscles twitch, 15) I have cramps in my stomach, 16) I feel like shooting up now. Higher score indicates increasing severity of opiate withdrawal syndrome.
