Brief Summary

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

This trial investigated the efficacy and safety of 400mg/day of lacosamide as compared to placebo in reducing the signs and symptoms of fibromyalgia syndrome.

Detailed Description

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

This was a proof-of-concept study and not powered for statistical comparisons.

The trial consisted of a 4-week Titration Phase, an 8-week Maintenance Phase, a 1-week Taper Phase, and a 2-week Safety Follow-Up Phase. If subjects met the eligibility criteria, they were randomized to receive either lacosamide 400mg/day or placebo during the Maintenance Phase. Subjects assigned to lacosamide were titrated from 100mg/day to 400mg/day at weekly intervals of 100mg. All subjects who completed the 4-week Titration Phase entered an 8-week Maintenance Phase. No dose adjustment was allowed during the Maintenance Phase. The Treatment Phase was defined as the combined Titration and Maintenance Phases.
