  • Combination of local anesthetic bupivacaine and anti-inflam meloxicam
  • Applied directly to site of injury
  • Company expects to submit NDA in second half of 2018

Heron Therapeutics, Inc. (NASDAQ: HRTX) announced on 6/21/2018 that HTX-011 for postoperative pain management has received Breakthrough Therapy designation from the U.S. Food and Drug Administration (FDA). HTX-011 is an investigational, long-acting, extended-release formulation of the local anesthetic bupivacaine in a fixed-dose combination with the anti-inflammatory meloxicam for the management of postoperative pain.

Breakthrough Therapy designation is designed to expedite the development and review of drugs that are intended to treat serious conditions and for which preliminary clinical evidence indicates substantial improvement over available therapies on clinically significant endpoint(s). Breakthrough Therapy designation was granted for HTX-011 based on the results of Phase 2 studies and two recently completed Phase 3 studies, which showed that HTX-011 produced significant reductions in both pain intensity and the need for opioids through 72 hours post-surgery compared to placebo and bupivacaine solution, the standard of care.

“We are pleased that HTX-011 has received Breakthrough Therapy designation from the FDA,” said Barry D. Quart, Pharm.D., Chief Executive Officer of Heron Therapeutics. “HTX-011 is the only long-acting local anesthetic to demonstrate significantly reduced postoperative pain and opioid use through 72 hours compared to bupivacaine solution, the standard-of-care local anesthetic for postoperative pain management, in Phase 3 studies. We look forward to working towards the submission of an NDA to the FDA for HTX-011 in the second half of 2018.”

HTX-011, which utilizes Heron’s proprietary Biochronomer® drug delivery technology, is an investigational, long-acting, extended-release formulation of the local anesthetic bupivacaine in a fixed-dose combination with the anti-inflammatory meloxicam for the management of postoperative pain. By delivering sustained levels of both a potent anesthetic and a local anti-inflammatory agent directly to the site of tissue injury, HTX-011 was designed to deliver superior pain relief while reducing the need for systemically administered pain medications such as opioids, which carry the risk of harmful side effects, abuse and addiction. HTX-011 has been shown to reduce pain significantly better than placebo or bupivacaine alone in five diverse surgical models: hernia repair, abdominoplasty, bunionectomy, total knee arthroplasty and breast augmentation. HTX-011 was granted Fast Track designation from the FDA in the fourth quarter of 2017 and Breakthrough Therapy designation in the second quarter of 2018. In the second half of 2018, Heron expects to submit a New Drug Application (NDA) to the FDA for HTX-011.
