$INSY Files Citizen Petition With the Drug Enforcement Administration

“CBD is a non-psychoactive compound found in the marijuana plant that offers the potential to provide a treatment option to patients suffering from a wide variety of diseases,” said Steve Sherman, Vice President, Regulatory Affairs, at Insys Therapeutics. “Importantly, Insys’s synthetic pharmaceutical CBD is a form of the compound that is identical in chemical structure to naturally-occurring CBD, but because it is not derived from marijuana, it is free of THC and other cannabinoid impurities, ensuring a consistent and controlled dosage with little or no potential for abuse.”

Independent comparison analyses conducted by Insys and the National Institute on Drug Abuse, part of the National Institutes of Health, have found that CBD synthetically produced by Insys Therapeutics is identical in chemical structure to plant-derived CBD.

The Citizen Petition to reschedule Insys’s synthetic pharmaceutical CBD outlines scientific and medical evidence that demonstrate the Company’s synthetic pharmaceutical CBD has no potential for abuse or dependency and, therefore, should be in Schedule IV or lower. More importantly, Insys’s synthetic pharmaceutical CBD has the potential to provide new treatment options for a wide variety of diseases, such as epilepsy, brain cancer, schizophrenia, post-traumatic stress disorder, anxiety, Alzheimer’s disease, neuropathic pain, Parkinson’s disease, diabetes, and many others.

The U.S. Drug Schedule System classifies drugs into five categories, or schedules, based on the drug’s acceptable medical use and abuse or dependency potential. Synthetic CBD’s classification as a Schedule I drug ranks the compound as similar to drugs such as heroin and cocaine. This means the process for obtaining the necessary approvals to conduct research from the various licensing bodies can take approximately one year, and a substantial commitment is required to execute the paperwork, inspection, and approval process. Outside the United States, effective June 1, 2015, CBD has been classified as a Schedule 4 substance by the Australian Therapeutic Goods Administration, which is the least restrictive schedule for prescription medicines in that country. In the United Kingdom, CBD is classified as a Class B medicinal product, and in Canada, CBD has been classified as a Schedule II medicinal product, both of which are less restrictive than Schedule I drugs in the U.S.

“Insys is asking the DEA to reschedule its synthetic pharmaceutical CBD as part of our continued commitment to advancing the research and development of cannabinoid therapies while striving to provide physicians and patients with consistent and controlled pharmaceutical options that can help improve the quality of life for patients,” said Michael Babich, President and Chief Executive Officer. “We are currently engaging with a broad range of stakeholders to build support for this Citizen Petition, in the hopes of addressing serious unmet medical needs.”

A Citizen Petition can be filed to ask that a governing agency, like the DEA or U.S. Food and Drug Administration, take, or refrain from taking, a particular action. Any person may file a Citizen Petition, and any person may comment on a petition that has been filed. Insys cannot predict when or if the DEA will respond to, or otherwise take any action with respect to the Citizen Petition filed.
