Study to Assess the Effectiveness and Safety of FLECTOR Patch for Treatment of Acute Back Strain

Multicenter, Open-Label Study to Assess the Effectiveness and Safety of FLECTOR Patch for Treatment of Acute Back Strain

Although approved for minor strains, sprains and contusions, FLECTOR Patch has not been studied extensively in the setting of acute back strain. This study is being conducted as an initial step in demonstrating the benefit of FLECTOR Patch specifically for back strain. In particular, this study is expected to provide information about the amount of improvement in back strain among subjects using the FLECTOR Patch, which may then be used to inform subsequent studies.

Inclusion Criteria:

Participants in the study must:

1. have acute, non-radicular back strain with onset up to 10 days before the first visit
2. have intact, non-damaged skin at the proposed patch application site
3. be untreated or unresponsive to conservative pain treatment regimens and/or opioids
4. have a minimum pain intensity score of four (4) or more on a scale of 1-10 (a rating of zero (0) being "no pain" and a rating of ten (10) being "pain as bad as you can imagine")
5. have a normal neurologic examination

Exclusion Criteria:

Participants may not be in the study if they:

1. have had surgery or other chronic pain condition within 3 months before first treatment
2. have back pain radiating below the knee at time of enrollment
3. have neuropathic pain or have been treated with gabapentin or pregabalin for neuropathy
4. are being treated for or are known to currently have kidney or liver disease
5. have certain other diseases or are using certain types of other drugs.
