Eligibility | Key Inclusion Criteria: - Plan to undergo an elective complete abdominoplasty (C-ABD), without collateral procedure or additional surgeries. - In the medical judgment of the investigator, be a reasonably healthy adult aged 18 - 65 years old, inclusive, and American Society of Anesthesiology (ASA) physical Class 1 or 2 at the time of randomization. - Unless the subject has a same sex partner, he or she must either be sterile (surgically or biologically) or commit to an acceptable method of birth control while participating in the study. - Have a body mass index = 35 kg/m². - Be willing and able to sign the informed consent form (ICF) approved by an Institutional Review Board (IRB). Key Exclusion Criteria: - In the opinion of the Investigator, have a concurrent painful condition that may require analgesic treatment during the study period or may confound post-surgical pain assessments. - Have a known allergy to chili peppers, capsaicin or the components of CA-008, acetaminophen, bupivacaine, fentanyl hydromorphone or oxycodone. - As determined by the investigator have a history or clinical manifestation of significant medical, neuropsychiatric or other condition, including a clinically significant existing arrhythmia, left bundle branch block or abnormal ECG, myocardial infarction or coronary arterial bypass graft surgery within the prior 12 months, significant abnormal clinical laboratory test value, or known bleeding abnormality that could preclude or impair study participation or interfere with study assessments. - The following are considered disallowed medications: 1. Be tolerant to opioids defined as those who have been receiving or have received chronic opioid therapy greater than 15 mg of oral morphine equivalents per day for greater than 3 out of 7 days per week over a one-month period within 6 months of screening. 2. Within 1 day prior to surgery and throughout the inpatient period, be taking any capsaicin-containing products, such as dietary supplements or over-the-counter (OTC) preparations, including topical formulations, and prescription medications. 3. Within the 7 days prior to surgery, be taking any central nervous system (CNS) active agent as an analgesic adjunct medication, such as anticonvulsants, antidepressants, benzodiazepines, sedative- hypnotics, clonidine and other central alpha-2 agents, ketamine or muscle relaxants. i. These drugs are permitted if prescribed for non-pain indications and the dose has been stable for at least 30 days prior to surgery. ii. The use of benzodiazepines and the non-benzodiazepines are permitted to treat insomnia during the postoperative period. |
