Heron Therapeutics Announces Financial Results for the Three and Six Months Ended June 30, 2020 and Highlights Recent Corporate Updates

SAN DIEGO, Aug. 5, 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 financial results for the three and six months ended June 30, 2020 and highlighted recent corporate updates.

Recent Corporate Updates

Pain Management Franchise

• Positive CHMP Opinion Received for ZYNRELEF™ for the Management of Postoperative Pain: In July 2020, the European Medicines Agency's (EMA) Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion, recommending the granting of a marketing authorisation for ZYNRELEF (formerly known as HTX-011), intended for the treatment of postoperative pain. The CHMP's positive opinion will now be reviewed by the European Commission (EC), with a final decision on the Marketing Authorisation Application expected in the coming months. An EC marketing authorisation through the centralized procedure is valid in all 27 European Union (EU) member countries as well as the European Economic Area countries. The CHMP recommended that ZYNRELEF be indicated for treatment of somatic postoperative pain from small- to medium-sized surgical wounds in adults. 
   
• Complete Response Letter Received from the FDA Regarding the NDA for HTX-011 for the Management of Postoperative Pain: In June 2020, Heron received a Complete Response Letter (CRL) from the U.S. Food and Drug Administration (FDA) regarding the New Drug Application (NDA) for HTX-011. The CRL stated that the FDA is unable to approve the NDA in its present form based on the need for additional non-clinical information. Based on the complete review of the NDA, the FDA did not identify any clinical safety or efficacy issues or chemistry, manufacturing and controls (CMC) issues. There are four non-clinical issues in the CRL, none of which relate to any observed toxicity. Three relate to confirming exposure of excipients in preclinical reproductive toxicology studies, and the fourth relates to changing the manufacturing release specification of the allowable level of an impurity based on animal toxicology coverage. We do not believe that any of the issues are significant barriers to ultimate approval, as all of the excipients have extensive histories of use in pharmaceuticals and the specification can be revised.
   
• Initiation of Phase 1b/2 Clinical Study of HTX-034 for the Treatment of Postoperative Pain: In May 2020, Heron initiated a Phase 1b/2 clinical study in patients undergoing bunionectomy of HTX-034, Heron's next-generation product for the treatment of postoperative pain. The study initiation followed clearance from the FDA of Heron's Investigational New Drug (IND) application for HTX-034 for the treatment of postoperative pain.

CINV Franchise

• Initiation of Phase 2 Clinical Study of CINVANTI^® for the Treatment of COVID-19: In July 2020, Heron initiated the GUARDS-1 Study, a Phase 2 clinical study evaluating CINVANTI (aprepitant) injectable emulsion in early hospitalized patients with Coronavirus Disease 2019 (COVID-19). The study initiation followed clearance from the FDA of Heron's IND application for CINVANTI for the treatment of COVID-19.
   
• CINV Net Product Sales: For the three and six months ended June 30, 2020, chemotherapy–induced nausea and vomiting (CINV) franchise net product sales were $22.7 million and $48.1 million, respectively, compared to $36.7 million and $68.3 million, respectively, for the same periods in 2019.
   
• CINVANTI Net Product Sales: Net product sales of CINVANTI for the three and six months ended June 30, 2020 were $22.6 million and $47.8 million, respectively, compared to $33.2 million and $61.2 million, respectively, for the same periods in 2019. Heron expects the impact of the generic arbitrage to be resolved in 2020, with a return to growth in 2021 and beyond.
   
• SUSTOL^® Net Product Sales: Net product sales of SUSTOL (granisetron) extended–release injection for the three and six months ended June 30, 2020 were $0.1 million and $0.3 million, respectively, compared to $3.5 million and $7.1 million, respectively, for the same periods in 2019. On October 1, 2019, the Company discontinued all discounting of SUSTOL, which resulted in significantly lower SUSTOL net product sales. Heron expects SUSTOL to return to growth in 2021 and beyond.
   
• 2020 Net Product Sales Guidance: Although Heron anticipates a decrease in new diagnoses and chemotherapy patient starts because of the onging COVID-19 pandemic, the Company is maintaining its 2020 guidance for net product sales for the CINV franchise of $70 million to $80 million.

"We are pleased with the CHMP's recent positive opinion for ZYNRELEF in the EU, and we remain committed to bringing this important non-opioid analgesic to patients in the U.S. as soon as possible. We have submitted a request for a Type A meeting with the FDA and look forward to working with the FDA to achieve this goal," said Barry Quart, Pharm.D., President and Chief Executive Officer of Heron. "In our CINV franchise, we are encouraged by the continued performance of CINVANTI during both a generic arbitrage period and the COVID-19 pandemic and are maintaining our 2020 net product sales guidance of $70 million to $80 million."

About HTX-011 (ZYNRELEF in the European Union) for Postoperative Pain

HTX-011 (ZYNRELEF in the European Union), 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 Fast Track designation from the U.S. Food and Drug Administration (FDA) in the fourth quarter of 2017 and Breakthrough Therapy designation in the second quarter of 2018. Heron submitted a new drug application (NDA) to the FDA for HTX-011 in October 2018 and received Priority Review designation in December 2018. A complete response letter (CRL) was received from the FDA regarding the NDA for HTX-011 on June 26, 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 ZYNRELEF in July 2020. Heron's New Drug Submission (NDS) for HTX-011 for the management of postoperative pain was granted Priority Review status by Health Canada in October 2019 and accepted by Health Canada in November 2019. Heron is working to respond to a list of questions received from Health Canada in July 2020.

About CINVANTI (Aprepitant) Injectable Emulsion

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, a substance P/neurokinin-1 (NK₁) receptor antagonist (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 United States prescribing information for CINVANTI is a 30-minute IV infusion or a 2-minute IV injection.

CINVANTI is under investigation for the treatment of COVID-19 as a daily 2-minute IV injection when added to the current standard of care.

About SUSTOL (Granisetron) Extended-Release Injection

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-HT₃ receptor antagonist 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).

About HTX-034 for Postoperative Pain

HTX-034, an investigational non-opioid, is a fixed-dose combination, extended–release solution of the local anesthetic bupivacaine, the nonsteroidal anti-inflammatory drug meloxicam and an additional agent that further potentiates the activity of bupivacaine. HTX-034 is formulated in the same proprietary polymer as HTX-011. By combining two different mechanisms that each enhance the activity of the local anesthetic bupivacaine, HTX-034 is designed to provide superior and prolonged analgesia. Local administration of HTX-034 in a validated preclinical postoperative pain model resulted in sustained analgesia for 7 days.
