Recent Corporate Updates

Acute Care Franchise

• ZYNRELEF:
    
  
  • Net product sales of ZYNRELEF (bupivacaine and meloxicam) extended-release solution for the three and twelve months ended December 31, 2022 were $3.9 million and $10.2 million, respectively. Net product sales of ZYNRELEF for the three and twelve months ended December 31, 2021 were $0.8 million and $2.9 million, respectively (ZYNRELEF was launched July 1, 2021). ZYNRELEF end-user (ambulatory surgical centers and hospitals) demand unit sales were 20,765 in the fourth quarter of 2022, representing an increase of 38% over the prior quarter. We currently expect first quarter 2023 ZYNRELEF demand unit sales to increase approximately 10% over the prior quarter.
       
  • Since launch on July 1, 2021 through December 31, 2022, 793 unique accounts purchased ZYNRELEF with 90% of those accounts reordering the product.
      
  • The supplemental New Drug Application (sNDA) for ZYNRELEF, to support the proposed indication for greatly expanded use of ZYNRELEF in soft tissue and orthopedic surgical procedures, was submitted in December 2022 to the U.S. Food and Drug Administration (FDA). The FDA assigned a Prescription Drug User Fee Act (PDUFA) goal date of October 23, 2023.
      
• APONVIE:
    
  
  • The APONVIE (aprepitant) injectable emulsion, the only intravenous (IV) substance P/neurokinin-1 (NK₁) receptor antagonist (RA) indicated for the prevention of postoperative nausea and vomiting (PONV) in adults, became commercially available in the U.S. in March 2023.
      
  • The Centers for Medicare and Medicaid Services granted pass-through payment status for APONVIE, effective April 1, 2023, under C-code C9145.
      
  • PONV represents a significant opportunity that leverages our existing sales organization in the acute care setting. There are approximately 36 million surgical procedures annually in patients at moderate to high risk for PONV, where guidelines recommend using multiple agents from different classes of drugs for prophylaxis.

Oncology Care Franchise

• 2022 Oncology Care Franchise Net Product Sales: For the three and twelve months ended December 31, 2022, oncology care franchise net product sales were $26.1 million and $97.5 million, respectively, compared to $19.9 million and $83.4 million, respectively, for the same periods in 2021.
    
• CINVANTI^® Net Product Sales: Net product sales of CINVANTI (aprepitant) injectable emulsion for the three and twelve months ended December 31, 2022 were $23.1 million and $87.3 million, respectively, compared to $17.4 million and $73.5 million, respectively, for the same periods in 2021.

• SUSTOL^® Net Product Sales: Net product sales of SUSTOL (granisetron) extended-release injection for the three and twelve months ended December 31, 2022 were $3.0 million and $10.2 million, respectively, compared to $2.5 million and $9.9 million, respectively, for the same periods in 2021.
    
• 2023 Oncology Care Franchise Net Product Sales Guidance: Heron currently expects full-year 2023 net product sales for the oncology care franchise of $99 million to $103 million.

"2022 was an important year for Heron, highlighted by the expansion of our acute care franchise to cover the two most common concerns for patients and clinicians after surgery, pain and nausea and vomiting. We were thrilled with the approval and recent launch of our fourth commercial product, APONVIE, for PONV, and remain encouraged with the continued growth of ZYNRELEF sales even in a quarter where seasonal declines are anticipated," said Barry Quart, Pharm.D., Chairman and Chief Executive Officer of Heron. "In our oncology care franchise, we saw strong growth, exceeding our full-year 2022 guidance with $97.5 million in net product sales. In addition, the significant reduction in cost of goods for CINVANTI achieved in the fourth quarter will have an important impact on reducing cash burn in 2023 and beyond."

Financial Results

Net product sales for the three and twelve months ended December 31, 2022 were $30.0 million and $107.7 million, respectively, compared to $20.7 million and $86.3 million, respectively, for the same periods in 2021.

Heron's net loss for the three and twelve months ended December 31, 2022 was $19.9 million, or $0.17 per share, and $182.0 million, or $1.67 per share, respectively, compared to $54.6 million, or $0.54 per share, and $220.7 million, or $2.24 per share, respectively, for the same periods in 2021. Net loss for the three and twelve months ended December 31, 2022 included non-cash, stock-based compensation expense of $10.5 million and $43.0 million, respectively, compared to $12.9 million and $46.9 million, respectively, for the same periods in 2021.

As of December 31, 2022, Heron had cash, cash equivalents and short-term investments of $84.9 million, compared to $157.6 million as of December 31, 2021. Net cash used for operating activities for the three and twelve months ended December 31, 2022 was $37.5 million and $146.9 million, respectively, compared to $45.3 million and $203.4 million, respectively, for the same periods in 2021. The decrease in our net cash used for operating activities was primarily due to the reduction in headcount implemented in June 2022 and changes in working capital, as well as a decrease in net loss.

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).
