SAN DIEGO, Aug. 5, 2019 /PRNewswire/ -- Heron Therapeutics, Inc. 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, 2019 and highlighted recent corporate updates.

Recent Corporate Updates

Pain Management Franchise

• Complete Response Letter Received from the FDA Regarding the NDA for HTX-011: A Complete Response Letter (CRL) was received from the U.S. Food and Drug Administration (FDA) on April 30, 2019 regarding the Company's New Drug Application (NDA) for HTX-011 for postoperative pain management. The CRL stated that the FDA is unable to approve the NDA in its present form based on the need for additional Chemistry, Manufacturing and Controls (CMC) and non-clinical information. Based on the complete review of the NDA, the FDA did not identify any clinical safety or efficacy issues, and there is no requirement for further clinical studies or data analyses.
• 95% of Postoperative Patients Remain Opioid-Free when HTX-011 Is Given with an Over-the-Counter Analgesic Regimen in Real-world Study in Hernia Repair Surgery: In May 2019, we announced the results of a multi-center postoperative pain management study in 93 patients that provides real-world evidence of opioid-free recovery in patients undergoing outpatient inguinal hernia repair surgery who received the investigational agent, HTX-011, together with a scheduled background regimen of generic over-the-counter (OTC) oral analgesics (acetaminophen and ibuprofen). Ninety-one percent (91%) of patients receiving HTX-011 with the OTC analgesic regimen were discharged without an opioid prescription, and none of these patients subsequently requested an opioid for postoperative pain.
• Results of Phase 3 EPOCH 1 Study Published: In May 2019, the results from the pivotal Phase 3 EPOCH 1 bunionectomy study of HTX-011 were published by the Regional Anesthesia & Pain Medicine journal.

• CINV 2019 Net Product Sales: For the three months ended June 30, 2019, chemotherapy-induced nausea and vomiting (CINV) franchise net product sales were $36.7 million, up 112% from the same period in 2018, and up 16% from the three months ended March 31, 2019. For the six months ended June 30, 2019, CINV franchise net product sales were $68.3 million, up 137% from the same period in 2018.

"We expect to meet with the FDA shortly to discuss our responses to the CRL for HTX-011, and we remain focused on resubmitting the NDA as soon as possible," said Barry Quart, Pharm.D., President and Chief Executive Officer of Heron. "Our CINV franchise continues to perform well, highlighted by strong net product sales in the second quarter."

About HTX-011 for Postoperative Pain

HTX-011, which utilizes Heron's proprietary Biochronomer^® drug delivery technology, is an investigational, long-acting, extended-release formulation of the local anesthetic bupivacaine in a fixed-dose combination with the anti-inflammatory meloxicam for the management of postoperative pain. By delivering sustained levels of both a potent anesthetic and a local anti-inflammatory agent directly to the site of tissue injury, HTX-011 was designed to deliver superior pain relief while reducing the need for systemically administered pain medications such as opioids, which carry the risk of harmful side effects, abuse and addiction. HTX-011 has been shown to reduce pain significantly better than placebo or bupivacaine solution in five diverse surgical models: hernia repair, abdominoplasty, bunionectomy, total knee arthroplasty and breast augmentation. HTX-011 was granted Fast Track designation from the FDA in the fourth quarter of 2017 and Breakthrough Therapy designation in the second quarter of 2018. Heron submitted an NDA for HTX-011 to the FDA in October of 2018 and received Priority Review designation in December of 2018. A CRL was received from the FDA regarding the NDA for HTX-011 on April 30, 2019 relating to CMC and non-clinical information. No issues related to clinical efficacy or safety were noted. An MAA for HTX-011 was validated by the EMA in March 2019 for review under the Centralised Procedure.

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, and nausea and vomiting associated with initial and repeat courses of moderately emetogenic cancer chemotherapy (MEC). 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). CINVANTI is the only IV formulation of an NK₁ RA indicated for the prevention of acute and delayed nausea and vomiting associated with HEC and nausea and vomiting associated with MEC that is free of polysorbate 80 or any other synthetic surfactant. The FDA-approved dosing administration included in the United States prescribing information for CINVANTI is a 30-minute infusion or a 2-minute injection.

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).
