Heron Therapeutics Initiates Phase 1 Clinical Study of HTX-011 for the Treatment of Post-Operative Pain

-Phase 1 single ascending-dose study in healthy volunteers to be completed in first quarter

-Phase 1b/2 studies in surgical patients to start in second quarter

REDWOOD CITY, Calif.--()--Heron Therapeutics, Inc. (NASDAQ:HRTX), a biotechnology company, today announced the initiation of a Phase 1 clinical trial of HTX-011, which is being developed for the treatment of post-operative pain. HTX-011 utilizes the Company’s proprietary Biochronomer® polymer-based drug delivery platform to release the local anesthetic bupivacaine and the anti-inflammatory meloxicam over an extended period.

The single-ascending dose, placebo-controlled study in healthy volunteers will evaluate safety, pharmacokinetics, and pharmacodynamics of the anesthetic effects of the product. HTX-011 has previously been shown to significantly reduce pain in a validated animal model for up to 72 hours following surgery.

“We look forward to rapidly completing our Phase 1 study of HTX-011, the lead product candidate in our post-surgical pain program, and expect to report initial results before the end of the first quarter of 2015,” commented Barry D. Quart, Pharm.D., Chief Executive Officer of Heron Therapeutics. “Concurrent to conducting the Phase 1 study, we are preparing for a series of Phase 1b/2 studies of HTX-011 in several post-surgical pain settings, and anticipate initiating the first of these in the second quarter, with data expected before the end of 2015.”
