REDWOOD CITY, Calif.--(BUSINESS WIRE)--Heron Therapeutics, Inc. (NASDAQ: HRTX) announced today that it has initiated a Phase 2 clinical trial of HTX-011, the Company's lead product candidate for the prevention of post-operative pain, following clearance from the U.S. Food and Drug Administration (FDA) of its Investigational New Drug (IND) application for HTX-011. HTX-011, which utilizes Heron's proprietary Biochronomer® drug delivery technology, is a long-acting formulation of the local anesthetic bupivacaine in a fixed-dose combination with the anti-inflammatory meloxicam.
"We are excited to be moving HTX-011, an innovative product candidate targeting the large and growing post-operative pain management market, into a Phase 2 study in an important surgical indication," commented Barry D. Quart, Pharm.D., Chief Executive Officer of Heron. "We believe that HTX-011 has the potential to meet our core goal of developing best-in-class medicines with the potential to significantly improve the lives of patients."The placebo-controlled, dose-finding, Phase 2 clinical trial in approximately 60 patients undergoing bunionectomy will evaluate the efficacy and safety of HTX-011, containing 200 mg or 400 mg of bupivacaine combined with meloxicam, compared to placebo. In a previously completed, placebo-controlled, Phase 1 clinical trial of HTX-011 in healthy volunteers, the desired pharmacokinetic profile for both bupivacaine and meloxicam was achieved, with therapeutically relevant drug levels of bupivacaine sustained for 2-3 days. Heron anticipates reporting top-line results from this Phase 2 clinical trial in the second half of 2015.
About HTX-011 for Post-Operative Pain
HTX-011, which utilizes Heron's proprietary Biochronomer® drug delivery technology, is a long-acting formulation of the local anesthetic bupivacaine in a fixed-dose combination with the anti-inflammatory meloxicam for the prevention of post-operative pain. The effective management of pain with a reduction in the use of opioids remains an important area of unmet medical need, and HTX-011 could potentially provide a differentiated therapeutic profile with advantages compared to currently available pain management options. In a Phase 1 clinical trial, HTX-011 achieved the desired pharmacokinetic profile for both bupivacaine and meloxicam. Therapeutically relevant plasma bupivacaine levels were sustained for 2-3 days in the absence of the large initial peak that can be observed with commercially available formulations. The anesthetic effects of HTX-011 persisted through 96 hours, which closely correlated with plasma bupivacaine concentrations, and HTX-011 was well-tolerated with no serious adverse events. Heron is currently conducting a placebo-controlled, dose-finding, Phase 2 clinical trial of HTX-011 in patients undergoing bunionectomy.
About Heron Therapeutics, Inc.
Heron Therapeutics, Inc. is a biotechnology company focused on developing and commercializing best-in-class pharmaceutical products that address major unmet medical needs. The Company has four product candidates in development for patients suffering from cancer and pain and has retained commercial rights to each of these in all major markets. SUSTOL® is an injectable, extended-release formulation of granisetron that is being developed for the prevention of both acute and delayed chemotherapy-induced nausea and vomiting (CINV) following the administration of moderately emetogenic chemotherapy (MEC) or highly emetogenic chemotherapy (HEC) agents. Affecting 70-80% of patients undergoing chemotherapy, CINV is one of chemotherapy's most debilitating side effects and is a leading cause of premature discontinuation of cancer treatment. Heron recently reported positive, top-line results from its Phase 3 MAGIC study and intends to resubmit its New Drug Application (NDA) for SUSTOL to the U.S. Food and Drug Administration (FDA) in mid-2015. HTX-019, also being developed for the prevention of CINV, has the potential to become the first polysorbate 80-free, intravenous formulation of aprepitant, a neurokinin-1 (NK1) receptor antagonist. Heron intends to file an NDA for HTX-019 using the 505(b)(2) pathway in the second half of 2016. HTX-011, a long-acting formulation of the local anesthetic bupivacaine in a fixed-dose combination with the anti-inflammatory meloxicam, is in Phase 2 clinical development for the prevention of post-operative pain. HTX-003, a long-acting formulation of buprenorphine, is being developed for the potential management of chronic pain and opioid addiction. Many of Heron's product candidates utilize its proprietary Biochronomer® drug delivery technology, which can deliver therapeutic levels of a wide range of otherwise short-acting drugs over a period of days to weeks with a single injection.
