A Study of Thienorphine Hydrochloride Tablets in Relapse Prevention

Status Not yet recruiting

Clinical Trial Summary

Opioid addiction is common worldwide. Thienorphine hydrochloride is a newly partial opioid receptor agonist drugs. It`s affinity with opioid receptors was much higher than opioids, which could effectively prevents opioid dependence by stop opioids competition for opioid receptors and causing opioid dependence. The aim of this research was to determine whether thienorphine hydrochloride would reduce opioid use and better preventing relapse among opioid addicts.

Clinical Trial Description

Opioids dependence is a chronic brain disease, with a much higher rate of relapse rate. Relapse prevention is important for opioid dependence treatment. Thienorphine hydrochloride, derivatives of buprenorphine, is one of the receptor partial agonists. Previous research indicated that, it may be a safe and effective treatment for the prevention of opioid dependent patients after detoxification. In this multicenter, randomized, double-blind, placebo-controlled, phase Ⅱb clinical trial, we are aimed to evaluate the efficacy of thienorphine hydrochloride tablets for anti-relapse therapy after opioid dependence detoxification treatment, determining the optimal dose of thienorphine hydrochloride tablets, and further evaluate the safety of thienorphine hydrochloride for patients with opioid dependence. 180 eligible patients are going to be recruited and randomly assigned to 0.2mg/day group, 0.5mg/day group and placebo control group after they provided their consent forms. Subjects in each group would receive assigned treatment for 12 weeks. Primary outcome measure was retention time of each participants during these 12 weeks. Urine test for opioids, changing of withdrawal score and craving, self-reported euphoria after using heroin, subjects and researchers' overall evaluation of treatment efficacy are secondary outcome measures. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
