Open-Label CA-008 (Vocacapsaicin) in Bunionectomy

September 29, 2021 updated by: Concentric Analgesics

An Open-Label Study of Intraoperative CA-008 Administration in Subjects Undergoing Bunionectomy

A Phase 2, open-label study of CA-008 to evaluate post-surgical pain control with CA-008.

Study Overview

Detailed Description

This is a Phase 2, single-center, open-label study evaluating a single dose of CA-008 4.2 mg administered with different standard-of-care anesthetic regimens during an elective unilateral transpositional first metatarsal osteotomy for the correction of hallux valgus deformity (bunionectomy).
