What this trial studies

This clinical trial investigates the effectiveness of CPL-01 in reducing postoperative pain and opioid use following a bunionectomy. Participants will be randomly assigned to receive either the investigational drug, a positive control, or a negative control during their surgery. After the procedure, subjects will be monitored for 72 hours in the hospital, with follow-up assessments at 7 and 30 days to evaluate pain levels and medication usage. The goal is to determine if CPL-01 can provide better pain management compared to the other treatments.

Who should consider this trial

Good fit: Ideal candidates are individuals scheduled for elective primary unilateral distal bunionectomy with a BMI of 39 kg/m2 or less.

Not a fit: Patients who have previously undergone bunion surgery or have concurrent painful conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could lead to improved pain management and reduced reliance on opioids for patients undergoing bunion surgery.

How similar studies have performed: Other studies have shown promise with similar approaches in pain management, but this specific intervention is novel.
