Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Phase 2, single center, randomized, double-blind, placebo-controlled, parallel design study of CA-008 vs. placebo in subjects undergoing an elective C-ABD under general anesthesia supplemented with a bupivacaine hydrochloride (HCl)transverse abdominis plane (TAP) block.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase 2, single-center, randomized, double-blind, placebo-controlled, parallel design study evaluating up to 4 ascending dose level cohorts, each evaluating a single dose of CA-008 vs. placebo injected/instilled during an elective C-ABD. Up to 72 subjects may be randomized in 4 cohorts.

For each subject, postsurgical assessments will be conducted in two parts:

* Inpatient period: starts with completion of study treatment injection (T0) and continues through 96 hours (T96h).
* Outpatient period: begins on discharge from the inpatient unit through various follow up visits to day 29 (D29)/week 4 (W4) after surgery. Note that additional follow up visits may occur at any time or even after D29/W4 to follow adverse events (AEs) to resolution or establishment of a new baseline.

* 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.
