SAN DIEGO, Aug. 14, 2023 /PRNewswire/ -- Heron Therapeutics, Inc. (Nasdaq: HRTX) ("Heron" or the "Company"), a commercial-stage biotechnology company focused on improving the lives of patients by developing and commercializing therapeutic innovations that improve medical care, today announced financial results for the three and six months ended June 30, 2023 and highlighted recent corporate updates.

"During the second quarter of 2023, the new executive management team has been focused on resizing the business and recently announced a cost reduction program that is anticipated to save the Company approximately $75 million in cash spend through 2025," said Craig Collard, Chief Executive Officer of Heron. "We are in the early stages of revamping Heron into a commercially focused company with efficient operations. As we move through the remainder of 2023, our team is focused on commercial execution and we look forward to updating you on those efforts in the near-term.  In addition to the cost-cutting, we were able to bolster the balance sheet by completing a $30 million equity financing with some of our largest shareholders, as well as closing on a $50 million working capital facility. Based on our current operational plan, we expect that this will provide the Company with enough capital to achieve profitability."

About ZYNRELEF for Postoperative Pain 

ZYNRELEF is the first and only dual-acting local anesthetic 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 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 initially approved by the FDA in May 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. In December 2021, the FDA approved an expansion of ZYNRELEF's indication. In December 2022, we submitted an sNDA to support the proposed indication for greatly expanded use of ZYNRELEF in soft tissue and orthopedic surgical procedures. On July 31, 2023, the FDA notified Heron of an extension of the PDUFA approval goal date by three months to provide for a full review of the submission. The FDA has set a new extended PDUFA approval goal date of January 23, 2024. ZYNRELEF is now indicated in the U.S. in adults for soft tissue or periarticular instillation to produce postsurgical analgesia for up to 72 hours after foot and ankle, small-to-medium open abdominal, and lower extremity total joint arthroplasty surgical procedures. Safety and efficacy have not been established in highly vascular surgeries, such as intrathoracic, large multilevel spinal, and head and neck procedures. ZYNRELEF was granted a marketing authorization by the European Commission in September 2020 and by the United Kingdom Regulatory Authority in January 2021. In August 2023, we cancelled the U.K. marketing authorization for ZYNRELEF, as we do not plan to commercially launch ZYNRELEF in the U.K. As of August 2, 2023, ZYNRELEF is approved in 30 European countries including the countries of the European Union and the European Economic Area. ZYNRELEF is indicated in Europe for the treatment of somatic postoperative pain from small- to medium-sized surgical wounds in adults.

About APONVIE for Postoperative Nausea and Vomiting (PONV)

Delivered via a 30-second IV push, APONVIE 32 mg was demonstrated to be bioequivalent to oral aprepitant 40 mg with rapid achievement of therapeutic drug levels. APONVIE is the same formulation as Heron's approved drug product CINVANTI. APONVIE is supplied in a single-dose vial that delivers the full 32 mg dose for PONV. APONVIE was approved by the FDA in September 2022 and became commercially available in the U.S. on March 6, 2023.

About CINVANTI for Chemotherapy Induced Nausea and Vomiting (CINV) Prevention 

CINVANTI, in combination with other antiemetic agents, is indicated in adults for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of highly emetogenic cancer chemotherapy (HEC) including high-dose cisplatin as a single-dose regimen, delayed nausea and vomiting associated with initial and repeat courses of moderately emetogenic cancer chemotherapy (MEC) as a single-dose regimen, and nausea and vomiting associated with initial and repeat courses of MEC as a 3-day regimen. CINVANTI is an IV formulation of aprepitant, an NK₁ RA. CINVANTI is the first IV formulation to directly deliver aprepitant, the active ingredient in EMEND^® capsules. Aprepitant (including its prodrug, fosaprepitant) is the only single-agent NK₁ RA to significantly reduce nausea and vomiting in both the acute phase (0–24 hours after chemotherapy) and the delayed phase (24–120 hours after chemotherapy). The FDA-approved dosing administration included in the U.S. prescribing information for CINVANTI include 100 mg or 130 mg administered as a 30-minute IV infusion or a 2-minute IV injection.

About SUSTOL for CINV Prevention 

SUSTOL is indicated in combination with other antiemetics in adults for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of moderately emetogenic chemotherapy (MEC) or anthracycline and cyclophosphamide (AC) combination chemotherapy regimens. SUSTOL is an extended-release, injectable 5-hydroxytryptamine type 3 RA that utilizes Heron's Biochronomer^® drug delivery technology to maintain therapeutic levels of granisetron for ≥5 days. The SUSTOL global Phase 3 development program was comprised of two, large, guideline-based clinical studies that evaluated SUSTOL's efficacy and safety in more than 2,000 patients with cancer. SUSTOL's efficacy in preventing nausea and vomiting was evaluated in both the acute phase (0–24 hours after chemotherapy) and delayed phase (24–120 hours after chemotherapy).
