Heron Therapeutics Announces U.S. FDA Approval of ZYNRELEF™ (HTX-011) for the Management of Postoperative Pain for up to 72 Hours

 

- ZYNRELEF is the first and only FDA-approved extended-release dual-acting local anesthetic, clinically proven to manage pain and to eliminate the need for opioids for up to 72 hours following surgery better than bupivacaine solution, the current standard-of-care -

- Full U.S. commercial launch of ZYNRELEF is planned for July 2021 -

- Conference call and webcast today at 8:30 am ET -

SAN DIEGO, May 13, 2021 /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 U.S. Food and Drug Administration (FDA) has approved ZYNRELEF (bupivacaine and meloxicam) extended-release solution for use in adults for soft tissue or periarticular instillation to produce postsurgical analgesia for up to 72 hours after bunionectomy, open inguinal herniorrhaphy and total knee arthroplasty. ZYNRELEF, the first and only extended-release dual-acting local anesthetic (DALA), delivers a fixed-dose combination of the local anesthetic bupivacaine and a low dose of the nonsteroidal anti-inflammatory drug (NSAID) meloxicam. The synergy between bupivacaine and meloxicam in ZYNRELEF has resulted in patients experiencing significantly less pain, including severe pain, and significantly more patients requiring no opioids (opioid-free) after surgery as compared to bupivacaine solution, the current standard-of-care.  

“The approval of ZYNRELEF marks an exciting milestone for patients, healthcare providers and pain management. Not just because it can reduce postoperative pain for up to 72 hours, but because for many patients it can eliminate the need for opioids after surgery,” said Barry Quart, Pharm.D., Chairman and Chief Executive Officer of Heron. “We are in a strong position to launch ZYNRELEF, given our highly successful hospital launch of CINVANTI and our pricing and unprecedented value proposition, which will ensure broad access for patients and healthcare providers. Our existing commercial team will immediately begin working with current accounts to gain formulary access, with full commercial availability expected by July 2021.”

ZYNRELEF is the first and only therapy for postoperative pain management to be rigorously tested in Phase 3 studies and demonstrate superiority to bupivacaine solution. ZYNRELEF demonstrated superior, sustained postoperative pain relief for up to 72 hours and decreased the need for opioids, with more patients opioid-free compared to bupivacaine solution. Clinical studies included over 1,000 patients, with the most common adverse reactions following ZYNRELEF administration being constipation, vomiting, and headache.

“The first three days after surgery are when patients experience the most severe postsurgical pain and are most likely to receive opioids to manage that pain. With the impressive reduction in pain and opioid use demonstrated by ZYNRELEF, we now have an important new option to help many patients achieve an opioid-free recovery,” said Roy G. Soto, M.D., anesthesiologist at Beaumont Health System. “The dramatic increase in opioid-related deaths last year highlights the significant need for safe, effective and non-addictive options to manage pain that decrease opioid exposure and reduce the need for opioid prescriptions after surgery.”

“Approximately 50 million Americans undergo surgery annually, and up to 67 percent of those patients receive opioids,” said Alan Rechter, M.D., Orthopaedic Surgeon at Orthopaedic Associates LLP. “Inadequate postoperative pain management has been associated with poor patient outcomes, causing a substantial burden on public health and contributing to recovery delays. Through today’s approval of ZYNRELEF, we now have a new therapy to offer patients, with the potential to meaningfully impact the postoperative pain management landscape and reduce, and even eliminate, unnecessary exposure to opioids in many patients.”

Conference Call and Webcast

 

Heron will host a conference call and webcast on May 13, 2021 at 8:30 am ET. The conference call can be accessed by dialing 877-311-5906 for domestic callers and 281-241-6150 for international callers. Please provide the operator with the passcode 3922347 to join the conference call.

An archive of the teleconference and webcast will also be made available on Heron’s website for 60 days following the call.

 

Important Safety Information for Patients

 

ZYNRELEF contains an NSAID (non-steroidal anti-inflammatory drug), a type of medicine which:

 

can increase the risk of a heart attack or stroke that can lead to death. This risk increases with higher doses and longer use of an NSAID.

 

cannot be used during heart bypass surgery.

 

can increase the risk of gastrointestinal bleeding, ulcers, and tears.

 

ZYNRELEF should also not be used if you are allergic to any components of ZYNRELEF, aspirin or other NSAIDs (such as ibuprofen or naproxen), or have had an asthma attack, hives, or other allergic reaction after taking any of these medicines; or as a paracervical block, during childbirth.

The most common side effects of ZYNRELEF are constipation, vomiting, and headache.

The medicines in ZYNRELEF (a local anesthetic and an NSAID) can affect the nervous and cardiovascular system; may cause liver or kidney problems; may reduce the effects of some blood pressure medicines; should be avoided if you have severe heart failure; may cause a rare blood disorder, or life-threatening skin or allergic reactions; may harm your unborn baby if received at 20 weeks of pregnancy or later; and may cause low red blood cells (anemia). Please see full Prescribing Information, including Boxed Warning.

About ZYNRELEFTM for Postoperative Pain

ZYNRELEF is the first and only dual-acting local anesthetic (DALA) that delivers a fixed-dose combination of the local anesthetic bupivacaine and a low dose of nonsteroidal anti-inflammatory drug meloxicam. ZYNRELEF is the first modified-release local anesthetic to be classified by FDA as an “extended-release” product because ZYNRELEF is also the first and only extended-release local anesthetic to demonstrate in Phase 3 studies significantly reduced pain and significantly increased proportion of patients requiring no opioids through the first 72 hours following surgery compared to bupivacaine solution, the current standard-of-care local anesthetic for postoperative pain control. ZYNRELEF was approved by the U.S. Food and

Drug Administration (FDA) on May 12, 2021 for use in adults for soft tissue or periarticular instillation to produce postsurgical analgesia for up to 72 hours after bunionectomy, open inguinal herniorrhaphy and total knee arthroplasty. Safety and efficacy have not been established in highly vascular surgeries, such as intrathoracic, large multilevel spinal, and head and neck procedures. In September 2020, the European Commission (EC) granted a marketing authorization for ZYNRELEF for the treatment of somatic postoperative pain from small- to medium-sized surgical wounds in adults. As of January 1, 2021, ZYNRELEF is approved in 31 European countries including the countries of the European Union and European Economic Area and the United Kingdom.

In 2020, drug overdoses were linked to more than 90,000 deaths the highest number ever recorded in a single year.3 Why Approval of ZYNRELEF is so Important Postoperative Opioids Can Be a Doorway to Addiction > 2 million Americans may become persistent opioid users annually after surgery. 1 More than 50 million surgical procedures happen in the United States.1 67% of patients filled an opioid prescription between 30 days before through 14 days after surgery.2* In addition, most patients take fewer opioids than the amount prescribed after surgery, resulting in excess opioid pills that are accessible to others.4 80% of patients report unused opioid tablets4 Up to 77% of opioid pills remain inside the home in unsecured locations4 51% of nonmedical users of opioids received them from friends and family5 References: 1.

Indication ZYNRELEF is indicated in adults for soft tissue or periarticular instillation to produce postsurgical analgesia for up to 72 hours after bunionectomy, open inguinal herniorrhaphy, and total knee arthroplasty. Limitations of Use Safety and efficacy have not been established in highly vascular surgeries, such as intrathoracic, large multilevel spinal, and head and neck procedures. ZYNRELEF Approved Indications and Limitations of Use

Slide 6

ZYNRELEF is first modified-release local anesthetic to be classified by FDA as an “extended-release” product ZYNRELEF only product to demonstrate superiority to immediate release bupivacaine HCL for 72 hours 72-hour duration in the indication statement Registrational studies in clinical data section in indicated procedures include pain curves showing 72-hour duration of activity and superiority to standard of care Focus is on opioid-free results in clinical data section as both statistically superior and clinically meaningful Standard NSAID class warnings included, with modifications due to single-dose local application allowing for additional NSAID use in multimodal analgesia (MMA) with monitoring Unique Labeling Attributes for ZYNRELEF Extended-Release Solution

Slide 7

Rather than approving a broad indication based on 1 soft tissue and 1 bony surgical model, FDA approved other modified-release local anesthetics for specific indications based on positive randomized, controlled trials in specific surgical procedures starting in 2020. Heron sought advice from FDA throughout development to discuss requirements for a broad label for ZYNRELEF, the only modified-release local anesthetic to demonstrate superiority to bupivacaine solution Based on these discussions with FDA, Heron believed that the studies submitted in the ZYNRELEF NDA would be sufficient to obtain a broad indication One week prior to PDUFA, FDA informed Heron more PK and safety data would be required to support additional surgical procedures Heron has multiple studies in process intended to support expanded labelling FDA Approach to Modified-Release Local Anesthetics Changed Following Withdrawal of Guidance on Analgesic Indications
