Study Endpoints

Primary Endpoints

Peak SOWS Scores at Baseline and Over Time
Baseline (pre-dose day 6) and at days 6, 7, 8, 9, 10, 11, 12, 13, and 14 post-dose

Short Opiate Withdrawal Scale (SOWS)-Gossop: The SOWs scale is a validated 10-item patient-reported scale designed to measure the symptoms of withdrawal in subjects who are dependent on opioids. Each of the 10 items represents a symptom: "feeling sick," "stomach cramps," "muscle spasms/twitching," "feeling of coldness," "heart pounding," "muscular tension," "aches and pains," "yawning," "runny eyes," and "insomnia/problems sleeping." Scores on the SOWS-Gossop can range from 0 to 30, with higher scores indicating greater severity of withdrawal symptoms.

Secondary Endpoints
