Under development for management of postoperative pain for 5 to 7 days

HTX-034 is Heron’s next-generation product in development for the treatment of postoperative painHTX-034, an investigational non-opioid, is a fixed-dose combination, extended-release solution of the local anesthetic bupivacaine, the nonsteroidal anti-inflammatory drug meloxicam, and an additional agent, aprepitant, that further potentiates the activity of bupivacaine. HTX-034 is formulated in the same proprietary polymer as ZYNRELEF®️. By combining two different mechanisms that each enhance the activity of the local anesthetic bupivacaine, HTX-034 is designed to provide superior and prolonged analgesia. Local administration of HTX-034 in a validated preclinical postoperative pain model resulted in sustained analgesia for 7 days.

In May 2020, Heron announced the clearance of the U.S. Investigational Drug (IND) application for HTX-034 for the treatment of postoperative pain by the Food and Drug Administration. The first-in-human Phase 1b study of HTX-034 in patients undergoing surgery has been completed and the Phase 2 portion of the study started in the first quarter of 2021.
