$INSY DEA Schedules Syndros (dronabinol oral solution) as Schedule II Drug

On July 1, 2016, the Food and Drug Administration (“FDA”) approved the New Drug Application for Syndros.

Dr. Santosh Vetticaden, Ph.D., M.D., Interim CEO, and Chief Medical Officer, stated, “Insys is looking forward to bringing this new drug product to chemotherapy patients to help alleviate their nausea and vomiting and AIDS patients with anorexia associated weight loss, respectively.”

“We look forward to interacting with the FDA to finalize the labeling and subsequent launch of Syndros in the second half of 2017,” concluded Vetticaden.

Important Safety Information

Syndros is a cannabinoid indicated in adults for the treatment of:

• Anorexia associated with weight loss in patients with AIDS, and
• Nausea and vomiting associated with cancer chemotherapy in patients who have failed to respond adequately to conventional antiemetic treatments

The use of dronabinol may cause psychiatric and cognitive effects and impair mental and/or physical abilities.
Patients with cardiac disorders may experience hypotension, hypertension, syncope or tachycardia.
May cause disulfiram-like reaction.
Weigh the potential risk versus benefits before prescribing Syndros to patients with a history of seizures, including those requiring anti-epileptic medication or other factors that lower the seizure threshold.
Assess risk for abuse or misuse in patients with a history of substance abuse or dependence, prior to prescribing Syndros and monitor for the development of associated behaviors or conditions.
Consider dose reduction or discontinuation, if worsening of symptoms while on treatment.
The safety and effectiveness of Syndros have not been established in pediatric patients.
