News Release Details

SAN DIEGO--(BUSINESS WIRE)--May 10, 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 biggest unmet patient needs, today reported financial results for the three months ended March 31, 2017 and highlighted recent corporate progress.

Recent Corporate Progress

Pain Franchise

• Expanded Phase 2 Program of HTX-011 with Initiation of TKA and Nerve Block Studies. Heron initiated Phase 2 studies of HTX-011 in two new surgical models, total knee arthroplasty (TKA) and breast augmentation (pectoral pocket nerve block), to complement its four successful Phase 2 studies in abdominoplasty, bunionectomy, and hernia repair. Heron anticipates initiating Phase 3 studies of HTX-011 this year and filing a New Drug Application (NDA) in 2018.

CINV Franchise

• SUSTOL^® Sales Increase; Product Added to National Comprehensive Cancer Network (NCCN^®) Antiemesis Guidelines. Net product sales of SUSTOL (granisetron) extended-release injection for the three months ended March 31, 2017 were $3.6 million, compared to $1.3 million for the three months ended December 31, 2016. In addition, SUSTOL was granted a Category 1 recommendation by the NCCN for use in the prevention of acute and delayed chemotherapy-induced nausea and vomiting (CINV) in patients receiving highly or moderately emetogenic chemotherapy (HEC or MEC). The NCCN guidelines identify SUSTOL as a "preferred" agent for preventing CINV following MEC and highlight the unique, extended-release formulation of SUSTOL.
• Received Notice of CINVANTI™ (HTX-019) PDUFA Date. The U.S. Food and Drug Administration (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. If approved, CINVANTI will strengthen Heron's CINV portfolio by adding a second, complementary therapeutic agent in this category.

"The first quarter of 2017 was a productive period for Heron, highlighted by the completion of several highly-successful Phase 2 studies of HTX-011 in multiple post-operative pain models and the inclusion of SUSTOL in the NCCN guidelines," said Barry D. Quart, Pharm.D., Chief Executive Officer of Heron. "Looking ahead, we are focused on the commencement of Phase 3 studies of HTX-011, as well as the approval of CINVANTI by year-end 2017."

Financial Results

In January 2017, Heron completed an underwritten public offering of its common stock for net proceeds of $163.7 million. As of March 31, 2017, the Company had cash, cash equivalents and short-term investments of $165.2 million, compared to $51.1 million as of December 31, 2016. Based on the Company's current operating plan and projections, it believes that available cash, cash equivalents and short-term investments are sufficient to fund operations for at least one year.

Net product sales of SUSTOL for the three months ended March 31, 2017 were $3.6 million, which represents 184% sequential quarter-over-quarter growth over the $1.3 million of net product sales of SUSTOL for the three months ended December 31, 2016.

Heron's net loss for the three months ended March 31, 2017 was $50.3 million, or $1.00 per share, compared to $33.4 million, or $0.92 per share for the same period in 2016. Net loss for the three months ended March 31, 2017, included non-cash, stock-based compensation expense of $8.0 million compared to $5.4 million for the same period in 2016.

Heron's net cash used for operating activities for the three months ended March 31, 2017 was $50.6 million, compared to $32.4 million for the same period in 2016.

The increases in net loss and net cash used for operating activities for the three months ended March 31, 2017 compared to the same period in 2016 were primarily due to increased clinical and manufacturing costs related to the development of HTX-011 and CINVANTI.
