SAN DIEGO--(EON: Enhanced Online News)--Heron Therapeutics, Inc. (NASDAQ: HRTX), a commercial-stage biotechnology company focused on developing novel best-in-class treatment solutions to address some of the biggest unmet patient needs, today announced positive topline results from its Phase 2 study of the investigational agent HTX-011 in subjects undergoing abdominoplasty (Study 203). HTX-011 demonstrated statistically significant reductions in both pain intensity and the use of opioid rescue medications through 96 hours following surgery.
“Today’s abdominoplasty results, combined with previously reported data from our Phase 2 programs in bunionectomy and hernia repair, demonstrate the potential for HTX-011 to provide broad utility and efficacy across multiple surgery types, from the smallest to one of the largest surgical incisions”
Study 203 is a randomized, placebo-controlled, dose-finding, Phase 2 clinical study evaluating the efficacy and safety of locally administered HTX-011 for post-operative anesthesia following abdominoplasty surgery. The Summed Pain Intensity (SPI) score through 96 hours post-surgery (SPI 0-96) was significantly reduced with HTX-011 and produced a statistically significant 36.6 percent reduction in pain through 96 hours following surgery, as measured by SPI 0-96 (p=0.0104). Pain was consistently reduced through 96 hours with statistically significant reductions observed between 24 to 48 hours (p=0.007), 48 to 72 hours (p=0.038), and 72 to 96 hours (p=0.016) after a single administration of HTX-011.
Additionally, HTX-011 produced significant reductions (p=0.011) in the use of opioid rescue medication through 96 hours following abdominoplasty, as compared to placebo. To date, HTX-011 continues to be generally well-tolerated in Phase 2.
“The most painful period following surgery is the first three to four days. Currently available local anesthetics do not have the duration of action to provide analgesia for these critical first few days. Poorly managed post-operative pain can result in impaired patient function, increased cost of care and potentially lead to chronic pain and long-term opioid use,” commented Harold S. Minkowitz, MD, Diplomat American Board of Anesthesiology, Department of Anesthesiology, Memorial Hermann Memorial City Medical Center. “However, the efficacy of HTX-011 in even one of the largest surgical incisions, like abdominoplasty, demonstrates its potential to provide durable post-operative pain relief in a wide variety of surgical procedures, reducing or eliminating the need for opioids.”
“Today’s abdominoplasty results, combined with previously reported data from our Phase 2 programs in bunionectomy and hernia repair, demonstrate the potential for HTX-011 to provide broad utility and efficacy across multiple surgery types, from the smallest to one of the largest surgical incisions,” said Barry D. Quart, Pharm.D., Chief Executive Officer of Heron Therapeutics. “The robust, long-lasting results seen across multiple surgical settings indicate that HTX-011 has the necessary attributes to be a best-in-class therapeutic for post-operative pain, extending relief following surgery and, in turn, reducing the need for, and risks associated with, opioid intervention.”
HTX-011 is the first long-acting anesthetic that is designed to address both post-operative pain and accompanying inflammation by combining the local anesthetic bupivacaine and the anti-inflammatory meloxicam in a single administration. Targeting both pain and inflammation has allowed HTX-011 to demonstrate an advantage over current standard of care in multiple surgical models in Phase 2 studies.

About HTX-011 for Post-Operative Pain
HTX-011, which utilizes Heron’s proprietary Biochronomer® drug delivery technology, is an investigational, long-acting formulation of the local anesthetic bupivacaine in a fixed-dose combination with the anti-inflammatory meloxicam for the prevention of post-operative pain. By delivering sustained levels of both a potent anesthetic and an anti-inflammatory agent directly to the site of tissue injury, HTX-011 was designed to deliver superior pain relief while potentially reducing the need for systemically administered pain medications such as opioids, which carry the risk of harmful side effects, abuse and addiction. HTX-011 is the subject of a broad-based Phase 2 development program designed to target the many patients undergoing a wide range of surgeries who experience significant post-operative pain. Following a planned End of Phase 2 meeting with the Food and Drug Administration, Heron anticipates initiating Phase 3 studies in 2017 and filing a New Drug Application in 2018.
