Brief Summary

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

The primary purpose of the study is to test the efficacy of 2 tablets (twice daily) of ABT-712, compared to placebo, administered over a 4-week period in participants with moderate to severe mechanical chronic low back pain (CLBP).

Detailed Description

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

The study used a randomized withdrawal design with an open label (OL) period prior to a double-blind (DB) period. Participants who were receiving benefit and were tolerating ABT-712 during the OL period were randomized into the DB period. Study drug was given for a total of 8 weeks, which included up to 3 weeks in OL, up to 4 weeks in DB, and a 1-week DB taper. During the OL period, all participants took increasing doses of ABT-712 until they were taking 2 tablets, twice daily. During the DB period, participants in the ABT-712 group took 2 ABT-712 tablets, twice daily throughout the 4 weeks, while participants in the placebo group took 2 placebo tablets twice daily.
