Study to Evaluate Botulinum Neurotoxin Serotype E (EB-001) in Reducing Musculoskeletal Pain in Abdominoplasty

A Phase 2 Study to Evaluate Safety and Efficacy of EB-001 Intramuscular (IM) Injections in Reducing Musculoskeletal Pain in Subjects Undergoing Elective Abdominoplasty Surgery

To determine the safety and efficacy of single intra-operative treatment of Botulinum Neurotoxin Serotype E (EB-001) intramuscular (IM) injections into the Rectus Abdominus (RA) in participants undergoing abdominoplasty.

Inclusion Criteria:

1. Men or women 23 to 55 years of age, inclusive

3. American Society of Anesthesiologist (ASA) Physical Class 1-2.

Exclusion Criteria:

1. History of prior major abdominal surgery as judged by the investigator
2. Pre-existing lung disease that could impact participant safety in the opinion of the investigator
3. Pre-existing disorders of the neuromuscular junction (myasthenia gravis, Eaton- Lambert syndrome, or amyotrophic lateral Sclerosis)
4. At high risk of deep vein thrombosis as judged by the investigators determined by a Caprini score of 3 or higher
5. Slow vital capacity that is below 80% of normal value for respective race, age, height, and gender or below 2.5 Liters (L) of absolute volume
6. Pulse oximetry below 95%
7. Body weight less than 50 kg (110 pounds) or a Body Mass Index (BMI) of ≥ 32
8. Reported use of any botulinum toxin within 3 months prior to the date of surgery
9. Use of long acting opioids within 3 days or any opioid medication within 24 hours prior to surgery
10. Aminoglycoside intake within 48 hours prior to or during surgery
11. Participants on anti-depressant or anti-psychotic medications
12. Reported pain score of 2 or more at screening on the 11-point scale numerical pain rating scale-administered after an activity (NPRS-A) following an activity after and walking approximately 10 feet.
