Brief Summary

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

The purpose of this study is to determine whether IPX159 is safe and effective in treating symptoms of RLS in subjects with Restless Legs Syndrome.

Detailed Description

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

IPX159 was developed as an extended release formulation to reduce the fluctuation in nefopam concentration compared to IR and to reduce the incidence of peak or rate related side effects.
