SAN DIEGO, Calif.--(BUSINESS WIRE)--Aug. 9, 2017-- Heron Therapeutics, Inc. (Nasdaq: HRTX) (the Company or Heron), a commercial-stage biotechnology company focused on developing novel, best-in-class treatments to address some of the most important unmet patient needs, today reported financial results for the three and six months ended June 30, 2017 and highlighted recent corporate progress.

Recent Corporate Progress

Pain Franchise

• Initiation of Phase 3 Program for HTX-011 in Postoperative Pain Following Successful End-of-Phase 2 Meeting with FDA. Heron reached a general agreement with the U.S. Food and Drug Administration (FDA) on the design and key elements for HTX-011’s Phase 3 program that will be required to support a New Drug Application (NDA). The program includes two pivotal Phase 3 efficacy studies in bunionectomy and hernia repair and an approximately 200-patient Phase 3 safety and pharmacokinetics study to meet the target patient numbers established by the FDA and to provide further evidence of the broad utility of HTX-011 across multiple surgical models. Importantly, the FDA noted that, beyond the agreed-upon Phase 3 studies, no additional clinical work is needed to meet the “Combination Rule” for fixed-dose combination products. The Phase 3 program is designed to achieve a broad indication for the reduction in postoperative pain for 72 hours and reduce the need for opioid analgesic medications following surgery. Heron recently initiated patient enrollment in its Phase 3 program and anticipates completing the Phase 3 program in the first half of 2018. Heron expects to file an NDA in 2018.
• Hired Key Talent. Anita Gupta, D.O., Pharm.D. joined Heron as Senior Vice President, Medical Strategy and Government Affairs and will be a key team member providing medical and regulatory input, and working with governmental agencies to support the use of opioid alternatives for postoperative pain. Dr. Gupta has led influential research, advocacy, community and healthcare policy efforts in pain medicine, anesthesiology and opioid prevention. Dr. Gupta is a board-certified anesthesiologist and internationally recognized pain specialist. She recently served as a member of the FDA’s Anesthetic and Analgesic Drug Products Advisory Committee and is a fellow at Princeton University at the Woodrow Wilson School.

CINV Franchise

• SUSTOL^® Sales Increase. Net product sales of SUSTOL (granisetron) extended-release injection for the three months ended June 30, 2017 were $8.5 million, compared to $3.6 million for the three months ended March 31, 2017.
• SUSTOL Guidance Increased. Based on results for the first half of 2017, Heron has increased its full year 2017 net product sales of SUSTOL guidance to a range of $25 to $30 million.
• CINVANTI™ (HTX-019) FDA Action Date in Q4 2017. The FDA set a Prescription Drug User Fee Act (PDUFA) goal date of November 12, 2017 for a decision on the Company’s NDA for CINVANTI.

“The first half of 2017 has been very exciting for Heron with the submission of the CINVANTI NDA, a successful End-of-Phase 2 meeting for HTX-011, and the excellent growth in net product sales of SUSTOL,” said Barry D. Quart, Pharm.D., Chief Executive Officer of Heron. “We have made important progress in the launch of SUSTOL and plan to build upon our success with the anticipated approval of CINVANTI by year-end 2017, which would add a second, complementary commercial product.”

Financial Results

Net product sales of SUSTOL for the three months ended June 30, 2017 were $8.5 million, which represents 134% sequential quarter-over-quarter growth, compared to the $3.6 million of net product sales of SUSTOL for the three months ended March 31, 2017. Net product sales of SUSTOL for the six months ended June 30, 2017 were $12.1 million.

Heron’s net loss for the three and six months ended June 30, 2017 was $42.8 million and $93.1 million, or $0.80 per share and $1.79 per share, respectively, compared to a net loss of $43.2 million and $76.7 million, or $1.17 per share and $2.09 per share, respectively, for the same periods in 2016. Net loss for the three and six months ended June 30, 2017, included non-cash, stock-based compensation expense of $8.2 million and $16.2 million, respectively, compared to $5.8 million and $11.2 million, respectively, for the same periods in 2016.

Heron’s net cash used for operating activities for the three months ended June 30, 2017 was $32.0 million, compared to $50.6 million for the three months ended March 31, 2017, a decrease of $18.6 million quarter-over-quarter. Net cash used in operating activities for the six months ended June 30, 2017 was $82.6 million, compared to $59.5 million for the same period in 2016. During the three months ended June 30, 2017, Heron repaid $25.0 million in principal on its outstanding secured promissory note payable.

Heron believes that its cash, cash equivalents and short-term investments of $109.3 million and accounts receivable of $18.6 million at June 30, 2017, along with collections from SUSTOL sales after June 30, 2017, provides the Company with funding sufficient to complete the HTX-011 pivotal Phase 3 efficacy studies in the first half of 2018.
