A Study to Evaluate EMB 001 in Subjects With Cocaine Use Disorder

Cocaine Use Disorder Clinical Trial

Official title: A Phase 2, Randomized, Double-Blind, Placebo-Controlled, Parallel Group, Study to Evaluate the Safety and Efficacy of EMB 001 in Subjects With Moderate-to-Severe Cocaine Use Disorder

Status Completed

Clinical Trial Summary

EMB-001 is a combination of 2 drugs: the cortisol synthesis inhibitor, metyrapone (Metopirone®), and the benzodiazepine receptor agonist, oxazepam (original trade name Serax®; now marketed as oxazepam (generic) only).

This is a Phase 2 study in approximately 80 adult subjects with moderate-to-severe Cocaine Use Disorder (CUD).

Clinical Trial Description

This study is a Phase 2, randomized, double-blind, placebo-controlled, parallel-group, study to compare the safety and efficacy of EMB-001 with a placebo control in approximately 80 subjects with moderate-to-severe CUD. Subjects will receive investigational medicinal product (IMP) during a 12-week, double-blind Treatment Period (Week 2 through Week 13) and a 1-week, double-blind Taper Period (Week 14).

After undergoing study procedures during the Screening and Baseline Periods, subjects who meet inclusion and exclusion criteria will then be randomized in a 1:1 ratio (n=40/arm) to one of the following for the Treatment Period (weeks 2 - 13) on Study Day 8:

• EMB-001 720 mg metyrapone/24 mg oxazepam mg BID, for a total daily dose of 1440 mg metyrapone and 48 mg oxazepam (Active Group)

• Placebo BID, (Placebo Group)

During the Taper Period (week 14), subjects in the Active Group will receive EMB-001 240/8 mg BID; and the Placebo Group will continue to receive placebo. Both groups will change from taking three capsules BID (twice daily) to one capsule BID (twice daily).

There will be a follow-up visit for safety assessments at Week 18. ;
