FDA Accepts New Drug Application (NDA) for Buprenorphine Sublingual Spray from INSYS Therapeutics

PHOENIX, Dec. 06, 2017 -- INSYS Therapeutics, Inc. (NASDAQ:INSY) (“INSYS” or “the company”), announced today that its New Drug Application (NDA) for a novel formulation of buprenorphine as a sublingual spray for the management of moderate-to-severe acute pain has been accepted for filing by the U.S. Food and Drug Administration (FDA).

Under the Prescription Drug User Fee Act (PDUFA), the FDA has set a target date of July 28, 2018 to complete its review of this NDA, which was based primarily on a pivotal trial that met its primary efficacy endpoint and several pharmacokinetics studies.

To expand the duration of exposure for this investigation new drug candidate, INSYS also recently completed a seven-day safety and tolerability study with 100 patients. Data from this study will be submitted to the FDA in the first quarter of 2018, augmenting the NDA package, and may impact the PDUFA date.

“We look forward to working with the FDA in 2018 to add our buprenorphine sublingual spray to the range of treatment options available to physicians whose patients suffer from moderate-to-severe acute pain,” said Steve Sherman, senior vice president of regulatory affairs at INSYS. “We believe that this novel formulation and delivery method of buprenorphine holds great promise as an alternative to traditional opioids.”

INSYS anticipates that the potential benefits of buprenorphine include a ceiling effect for respiratory depression and, compared to other opioids frequently used in this indication, less abuse potential, less cognitive impairment and less constipation.

“To support the progress of our product pipeline through the regulatory path, we set a goal this year to file one NDA per year for the next five years,” said Saeed Motahari, president and chief executive of INSYS. “With the FDA’s acceptance of our NDA for buprenorphine sublingual spray, we are off to a good start.” 

In addition to buprenorphine sublingual spray, INSYS is also developing treatments for a variety of conditions other than pain, including synthetic cannabidiol (CBD) for two types of pediatric epilepsy and Prader-Willi syndrome; dronabinol for anorexia-associated weight loss in cancer and agitation in Alzheimer’s disease; buprenorphine/naloxone sublingual spray for opioid dependence; naloxone nasal spray for opioid overdose; epinephrine nasal spray for anaphylaxis; and rizatriptan nasal spray for migraine.
