Efficacy and Safety of GRT6005 in Patients With Chronic Low Back Pain.

July 13, 2021 updated by: Tris Pharma, Inc.

Efficacy, Safety, and Tolerability of GRT6005 in Subjects With Moderate to Severe Chronic Low Back Pain.

The purpose of this trial is to evaluate the safety and efficacy of once daily orally administered GRT6005 in a total of 3 fixed doses compared to placebo in subjects with moderate to severe chronic Low Back Pain (LBP). The study includes a maximum of 21 days screening period followed by a 2-week titration period and 12-week maintenance double-blind treatment period and a 10-14 day safety follow up period. Patients who are eligible for the double-blind treatment period will be randomized to one of the following treatment groups: GRT6005 low-dose, GRT6005 medium dose, GRT6005 high-dose, Tapentadol or placebo.
