INSYS Therapeutics Extends ‘Compassionate Use’ Studies of Cannabidiol (CBD) for Refractory Pediatric Epilepsy
Extension of Expanded Access Program Enables Patients from Initial Trials to Continue Taking Investigational Medicine Under Their Physicians’ Supervision

PHOENIX, Oct. 09, 2017 (GLOBE NEWSWIRE) -- INSYS Therapeutics, Inc. (NASDAQ:INSY) (“INSYS” or “the company”), announced today that it has extended the compassionate use studies of its proprietary oral formulation of cannabidiol (CBD) for the treatment of refractory pediatric epilepsy, enabling patients from previous clinical trials of the investigational medicine to continue receiving it according to the protocols originally accepted by the U.S. Food and Drug Administration (FDA) and under the supervision of their physicians.

The original 48-week expanded access program followed a long-term safety study that permitted patients who had completed the initial 10-day safety and pharmacokinetics (PK) study to continue receiving the company’s CBD oral solution at doses up to 40 mg/kg/day for up to 48 weeks. In the initial safety and PK study, 61 patients with refractory epilepsy between the ages of 1 and 17 years received total daily doses of 10 mg/kg, 20 mg/kg or 40 mg/kg. Of these 61 patients, 52 continued into the long-term safety study, of which 45 have completed 48 weeks of treatment across multiple investigative sites in the United States.

Expanded access, also called “compassionate use,” provides a pathway for patients to gain access to investigational medicines before they are approved by the FDA.

Approximately 31 of the 45 patients in the long-term safety study of INSYS Therapeutics’ CBD oral solution for refractory pediatric epilepsy have enrolled in the expanded access program, including 12 under the care of Dr. Steven Phillips, M.D., a pediatric epileptologist affiliated with MultiCare Mary Bridge Children’s Hospital and Health Center and MultiCare Tacoma General Hospital in Tacoma, Wash.

“All 12 of our families are extremely grateful that they continue to get CBD for their children through the expanded access program for CBD from INSYS Therapeutics,” said Dr. Phillips, who is a principal investigator in the compassionate use studies. “Seizure control has continued to be much improved on CBD as compared to when not on CBD, and this effect has been maintained for several years. As importantly, we have seen minimal side effects with CBD and an overall improvement in the quality of life in our patients.”

INSYS decided to extend the expanded access program as a result of the patients’ continued response to treatment with the company’s formulation of CBD oral solution.

“We are delighted that children with a history of intractable seizures are benefiting from our investigational CBD oral solution,” said Saeed Motahari, president and chief executive officer of INSYS Therapeutics. “We admire and respect these brave kids and their parents for taking part in our early trials, which are among the first in this emerging area of medicine for refractory pediatric epilepsy. We also appreciate the tireless efforts of the pediatric epileptologists involved in the initial studies, which we believe will inform our future research on this novel compound.”
