– Over 90% of Hernia Repair Patients Receiving HTX-011 Required No Opioids to Manage Their Postoperative Pain Through 72 hours After Surgery –
SAN DIEGO, Sept. 16, 2020 /PRNewswire/ — Heron Therapeutics, Inc. (Nasdaq: HRTX), a commercial-stage biotechnology company focused on improving the lives of patients by developing best-in-class treatments to address some of the most important unmet patient needs, today announced that the results from EPOCH 2 follow-on study (NCT03695367) of the investigational agent HTX-011 in open inguinal hernia repair surgery with mesh, have been published online by the journal, Surgery in an article entitled “Opioid-free recovery following herniorrhaphy with HTX-011 as the foundation of a multimodal analgesic regimen.” In this study, more than 90% of patients receiving HTX-011, along with postoperative over-the-counter (OTC) acetaminophen and ibuprofen, remained opioid-free throughout the 72-hour period following hernia repair surgery. The mean pain intensity never rose above the mild range through 72 hours following surgery.
HTX-011 is a dual-acting, fixed-dose combination of the local anesthetic bupivacaine with a low dose of the nonsteroidal anti-inflammatory drug meloxicam. It is the first and only extended–release local anesthetic to demonstrate in Phase 3 studies (EPOCH 1 in bunionectomy and EPOCH 2 in hernia repair) significantly reduced pain and opioid use through 72 hours compared to bupivacaine solution, the current standard–of–care local anesthetic for postoperative pain control. HTX-011 was well tolerated, with a safety profile comparable to placebo and bupivacaine solution.
“Typically, the first 72 hours after surgery are the most difficult from a pain management perspective and is where patients experience the most severe pain requiring opioids,” said Jay Redan, M.D., Chief of Surgery at AdventHealth Celebration. “The EPOCH 2 follow-on study provides important evidence that HTX-011, along with OTC analgesics, can keep patients in the mild pain range, allowing more than 90% to remain opioid-free. The study was able to identify patients who should receive an opioid discharge prescription and has the potential to personalize postoperative pain management so that opioids are only prescribed to those who will need them after discharge. This can help to substantially limit the amount of opioids going home with patients following hernia repair surgery.”

About the EPOCH 2 Follow-On Study
The EPOCH 2 follow-on study was a multicenter, postoperative pain management study evaluating the efficacy and safety of locally administered HTX-011 300 mg bupivacaine / 9 mg meloxicam via needle-free application into the surgical site in combination with a postoperative non-opioid multimodal analgesia (MMA) regimen of over-the-counter oral acetaminophen and ibuprofen in 63 patients. The study included two sequential cohorts, with identical procedures and MMA regimens, except that patients in Cohort 2 also received an intraoperative dose of ketorolac (15 mg or 30 mg, based on age, renal function and weight) prior to wound closure. The goal was to increase the proportion of opioid-free patients by combining HTX-011 with a postoperative regimen of readily available, oral analgesics. Key results of the study include the following:
- In total, more than 90% of patients in this study did not require opioids to manage their postoperative pain during the first 72 hours.
- Across all study patients, 87% were opioid-free through Day 10 and 83% were opioid-free throughout the entire 28-day follow-up period of the study.
- Patients in the study who required an opioid during the 72-hour postoperative period could be identified retrospectively with the following algorithm: pain score ?6 at 2 hours postoperatively or received opioid rescue medication within the first 2 hours postoperatively.
- Mean pain intensity scores were similar between cohorts and never rose above the mild pain range (NRS <4) throughout the 72-hour postoperative period.
- Addition of an intraoperative dose of ketorolac did not provide additional benefit for pain intensity or opioid use.
HTX-011 was well tolerated, and co-administration with non-steroidal anti-inflammatory drugs did not affect the safety of HTX-011.
About HTX-011 for Postoperative Pain
HTX-011, an investigational non-opioid analgesic, is a dual-acting, fixed-dose combination of the local anesthetic bupivacaine with a low dose of the nonsteroidal anti-inflammatory drug meloxicam. It is the first and only extended-release local anesthetic to demonstrate in Phase 3 studies significantly reduced pain and opioid use through 72 hours compared to bupivacaine solution, the current standard-of-care local anesthetic for postoperative pain control. HTX-011 was granted Breakthrough Therapy designation and received Priority Review designation. A complete response letter (CRL) was received from the U.S. Food and Drug Administration (FDA) regarding the New Drug Application (NDA) for HTX-011 in June 2020 relating to non–clinical information. No clinical safety or efficacy issues and no chemistry, manufacturing and controls (CMC) issues were identified. The European Medicines Agency’s (EMA) Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion for HTX-011 under the proprietary name ZYNRELEFTM in July 2020. Heron’s New Drug Submission (NDS) for HTX-011 for the management of postoperative pain was granted Priority Review status and accepted by Health Canada. Heron is working to respond to a list of questions received from Health Canada in July 2020.
