·  Net Product Sales for First Quarter of 2023 Grew 26% to $29.6 million, Compared to First Quarter Net Product Sales in 2022

·  Appointment of Craig Collard as Chief Executive Officer (CEO) and Jason Grillot as Vice President (VP), Sales and Marketing, of the Acute Care Franchise.

SAN DIEGO, May 11, 2023 /PRNewswire/ -- Heron Therapeutics, Inc. (NASDAQ:HRTX) (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 months ended March 31, 2023 and highlighted recent corporate updates.

First quarter 2023 net product sales grew 26% to $29.6 million, compared to the first quarter of 2022. The sales growth was mainly driven by our oncology care franchise, which increased 15%, compared to the same period in 2022. First quarter also reflected continued advancement of our acute care franchise, with $3.5 million in net product sales from ZYNRELEF^® and initial orders from the launch of APONVIE^® in March.

With the appointment of Craig Collard as CEO in April and the recent hiring of Jason Grillot as VP of sales and marketing of the acute care franchise, the team is conducting a thorough review of the Company's business practices and strategies to develop a long-term plan that maximizes the potential of the Company. We have identified two areas of immediate priority for our commercial team: first, is to enhance the value of ZYNRELEF through a broader and deeper penetration of accounts; second, to address application issues through training and expanded indications. Further, we are looking at ways to reduce cash burn through improved operational efficiency. We look forward to updating investors on these fronts in the coming months.

Financial Results

Net product sales for the three months ended March 31, 2023 were $29.6 million, compared to $23.5 million for the same period in 2022.

For the three months ended March 31, 2023, total operating expenses were $62.7 million, compared to $86.4 million for the same period in 2022, representing a decrease of $23.7 million, or a 27% reduction year-over-year. This decrease was driven by cost management efforts and a reduction in development projects, offset by higher cost of goods sold and increased litigation expenses. Cost of product sales were $16.9 million in the first quarter of 2023, compared to $11.4 million for the same period in the prior year. The product gross margin rate decreased year-over-year primarily as a result of a one time inventory write-off due to short-dated product. Sales and marketing expenses decreased by $2.3 million, primarily due to a reduction in personnel expenses and external costs to support the ongoing commercialization of ZYNRELEF. Research and development expenses decreased by $28.3 million, primarily driven by lower personnel and project-related expenses, including manufacturing projects to increase operational efficiencies. General and administrative expenses increased by $1.3 million, primarily driven by increased litigation and activist shareholder issues.

Heron's net loss for the three months ended March 31, 2023 was $32.8 million, or $0.27 per share, compared to $63.9 million, or $0.63 per share, for the same period in 2022. Net loss for the three months ended March 31, 2023 included non-cash, stock-based compensation expense of $7.9 million, compared to $10.9 million for the same period in 2022.

As of March 31, 2023, Heron had cash, cash equivalents and short-term investments of $60.0 million, compared to $84.9 million as of December 31, 2022. Net cash used for operating activities for the three months ended March 31, 2023 was $24.9 million, compared to $43.9 million for the same period in 2022. The decrease in our net cash used for operating activities was primarily due to a decrease in net loss, the reduction in headcount implemented in June 2022 and changes in working capital.

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, and the FDA assigned a PDUFA goal date of October 23, 2023. 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.

About APONVIE for PONV

APONVIE is a substance NK₁ RA, indicated for the prevention of PONV in adults. 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.

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).
