Official title
Phase 3, Randomized, Multicenter, Double-Blind, Placebo-Controlled, Efficacy, Safety, and Dose-Response Study of Lofexidine for Treatment of Opioid Withdrawal (Days 1-7) Followed by Open-Label, Variable Dose Lofexidine Treatment (Days 8-14)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to look at the efficacy and safety for lofexidine hydrochloride, an alpha-2 adrenergic agonist under development for the treatment of acute withdrawal from short-acting opioids. The study takes place in 2 parts: a 7-day inpatient double-blind treatment portion where subjects will be randomly assigned to one of three doses of study medication (2.4 mg total daily dose of lofexidine, 3.2 mg total daily dose of lofexidine, or placebo) followed by an optional open-label treatment period where subjects will be inpatient or outpatient and receive lofexidine at variable dosing for up to an additional 7 days. The Investigator hypothesizes that subjects will achieve maximum treatment effect with tolerable side effects at the 3.2 mg total daily dose and that both the 3.2 mg and 2.4 total daily doses will show better efficacy over placebo in treating symptoms of acute opioid withdrawal.
