Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The primary purpose of this study is to evaluate the efficacy of medical cannabis aerosol containing 0.25, 0.5, 1.0 milligrams (mg) delta (Δ)9-tetrahydrocannabinol (THC) inhaled three times a day (TID) compared to placebo via the Fixed-dose Syqe Inhaler on pain intensity at Week 15.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study will assess the efficacy, safety, tolerability, and pharmacokinetics (PK) of medical cannabis aerosol inhaled via the Syqe Inhaler at nominal doses of 0 (placebo), 0.25, 0.5, and 1.0 mg TID of Δ9-THC added on to standard of care for treatment of DPNP.

The target sample size is 192 eligible participants worldwide, randomized from up to approximately 51 recruiting sites in up to approximately 8 countries.

The study consists of 1) a screening period of up to 14 days; 2) a 15-week, parallel-group, randomized, double-blind treatment period, including a 3-week up-titration period and a 12-week maintenance period; and 3) a post-treatment, safety follow-up period of 4 weeks.
