This is a Phase 3 clinical research study involving an oral, non-opioid, investigational medication in people with pain due to acute back muscle spasms.
Back pain is a condition that affects millions of people in the United States every year. When a person suffers from sudden onset (acute) of back muscle spasms (involuntary tensing of the muscles), it can result in short-term pain that may last a few weeks.
The purpose of the study is to determine if the investigational medication is safe and effective in study participants suffering from recent pain caused by acute back muscle spasms.
