Full Press Release Details
Heron Therapeutics Reports Positive Top-Line Results from Phase 2 Studies of HTX-011 for Management of
-Statistically and clinically significant reductions in pain intensity through 96 hours after bunion surgery and
through 48 hours after hernia surgery
-Increase in time to first opioid rescue and decrease in overall opioid use in both studies
-HTX-011 statistically superior to standard-of-care bupivacaine solution on both pain intensity and opioid use
-HTX-011 shown effective when administered by infiltration or by Mayo Block (nerve block)
-Instillation, an easier, less invasive and potentially safer route of administration into the wound, was equally as effective as injection
-Conference call and webcast at 8:30 a.m. ET on August 1
REDWOOD CITY, Calif. August 1, 2016 Heron Therapeutics, Inc. (NASDAQ: HRTX), a biotechnology company focused on improving the lives of patients
by developing best-in-class medicines that address major unmet medical needs, announced preliminary, positive, top-line efficacy results from two Phase 2 clinical studies of HTX-011, its lead product candidate for the management of post-operative
pain in patients undergoing bunionectomy (Study 208) and inguinal hernia repair (Study 202) and safety data from our ongoing Phase 2 program. HTX-011, which utilizes Heron s proprietary
Biochronomer drug delivery technology, is the first long-acting formulation of the local anesthetic bupivacaine in a fixed-dose combination with the anti-inflammatory meloxicam and is
designed to target both post-operative pain and its associated inflammation.
Study 208 Bunionectomy
Study 208 was a randomized, placebo- and active-controlled, double-blind Phase 2 clinical study in patients undergoing bunionectomy. This study evaluated the
efficacy and safety of two formulations of HTX-011 at 200 mg compared to the standard dose of bupivacaine solution and placebo. Bupivacaine solution is the standard-of-care agent for the
management of post-operative pain. In addition, HTX-011 was evaluated when administered via Mayo Block (nerve block via closed wound injection) or infiltration (open wound injection).
The primary endpoint was the difference as compared to placebo in pain intensity as measured by the Summed Pain Intensity (SPI) score in the first 24 hours
post-surgery (SPI 0-24). Key secondary endpoints included comparison to bupivacaine solution, the time to first use of opioid rescue medication, total opioid consumption and difference in pain intensity compared to placebo or bupivacaine solution
when administered as a Mayo Block or infiltration. The major findings for our Phase 3 formulation of HTX-011 are as follows:
Study 202 Inguinal Hernia Repair
Study 202 was a randomized, placebo-controlled, double-blind Phase 2 clinical study in patients undergoing inguinal hernia repair. The study evaluated the
efficacy and safety of two formulations of HTX-011 at two doses (200 mg and 400 mg), compared to placebo.
In addition, two routes of administration into
the wound (injection and instillation) were evaluated. Instillation into the incision site is an easier and potentially safer route of administration as it avoids multiple injections around the wound (as many as 10 or more in large operations) that
carry the risk of venous puncture.
The primary endpoint was the difference as compared to placebo in pain intensity as measured by SPI 0-24. Key
secondary endpoints included the time to first use of opioid rescue medication and total opioid consumption. The major findings for the 400 mg dose of our Phase 3 formulation of HTX-011 as compared to placebo are as follows:
HTX-011 has been generally well tolerated in the ongoing Phase 2 program, which has involved more than 250 administrations of HTX-011. The most frequent
treatment-related adverse events reported have been nausea and vomiting, which occurred at similar rates in active and control patients.
today s results in hand, we could not be more excited about the potential of HTX-011 to represent a best-in-class therapeutic for post-operative pain, commented Barry D. Quart, PharmD, Chief Executive Officer of Heron Therapeutics.
HTX-011 is the first extended-release local anesthetic to demonstrate significant benefit over bupivacaine solution, the standard of care
for the management of post-operative pain, following bunionectomy, one of the most painful surgeries. As we move toward our broad-based Phase 3 registration program, we remain focused on our goal
of delivering a therapeutic tool that can not only greatly reduce pain levels following surgery, but also help address the nationwide burden of opioid abuse and dependence.

About HTX-011 for Post-Operative Pain
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. By delivering sustained levels of both a potent anesthetic and an anti-inflammatory agent directly to the site of tissue injury, HTX-011 was designed to deliver superior pain
relief while potentially reducing the need for systemically administered pain medications such as opioids, which carry the risk of harmful side effects, abuse and addiction. HTX-011 is the subject of a broad-based development program designed to
target the many patients undergoing a wide range of surgeries who experience significant post-operative pain.
