Zynerba Pharmaceuticals Announces Positive Initial Results From ZYN002 CBD Gel Phase 1 Single Rising Dose Trial and Initiation of Phase 1 Multiple Rising Dose Trial

DEVON, PA, January 06, 2016 – Zynerba Pharmaceuticals, Inc. (NASDAQ: ZYNE), a specialty pharmaceutical company dedicated to the development of innovative transdermal synthetic cannabinoid treatments, today announced positive initial safety results from its Phase 1 single rising dose clinical trial of its ZYN002 cannabidiol (CBD) gel in development for the treatment of epilepsy, osteoarthritis and Fragile X Syndrome.  The Phase 1 study was a randomized, double-blind, placebo-controlled, clinical trial to assess the safety and pharmacokinetics of ZYN002 in 32 healthy volunteers and 12 patients with epilepsy. Initial results from the 32 healthy volunteers demonstrated that ZYN002 was safe and well tolerated at all four dose levels. There were no serious adverse events, no drug-related changes in ECGs or clinical laboratory values, and there were no discontinuations due to adverse events.  Overall, the incidence of adverse events associated with ZYN002 was similar to placebo.  In addition, ZYN002 demonstrated no impairment in the trail making test, a neuropsychological test of visual attention and task switching, which detects several cognitive impairments. Final results, including results from patients with epilepsy, are expected in the first half of 2016.

The Company also announced the initiation of a second Phase 1 clinical trial for ZYN002. The randomized, double-blind, placebo controlled trial, titled the “Multiple Rising Dose Study in Healthy Volunteers and Patients with Epilepsy,” will evaluate the pharmacokinetic profile and tolerability of ZYN002 in 16 healthy volunteers, followed by 12 patients with epilepsy. Results are expected in the first half of 2016.

“We are making rapid progress in the development of ZYN002 CBD Gel, having initiated the Phase 1 single rising dose trial only two months ago,” said Armando Anido, Chairman and CEO of Zynerba Pharmaceuticals. “Given the positive initial results from the single rising dose study in healthy volunteers, we look forward to the results of the multiple rising dose study in the first half of 2016.  There is significant interest in ZYN002 as the first transdermal formulation of CBD with a unique mechanism of action that bypasses the stomach and first pass metabolism in the liver, potentially resulting in increased bioavailability and greater tolerability.  Pending the results of these trials, we expect to initiate Phase 2 trials in three indications in the second half of 2016.”

About ZYN002 CBD Gel
Zynerba’s ZYN002 CBD Gel is the first and only synthetic CBD formulated as a patent-protected permeation-enhanced gel and is being studied in refractory epilepsy, Fragile X syndrome and osteoarthritis. ZYN002 is a clear, permeation-enhanced gel that is designed to provide consistent, controlled drug delivery transdermally with convenient once- or twice-daily dosing. Transdermal therapeutics are absorbed through the skin directly into the systemic circulation, avoiding first-pass liver metabolism and potentially enabling lower dosage levels of active pharmaceutical ingredients and rapid and reliable absorption with high bioavailability. In addition, transdermal delivery avoids the gastrointestinal tract and potential stomach acid degradation of CBD into THC (associated with psychoactive effects), as demonstrated in a Zynerba in vitro study.

About Epilepsy
Epilepsy is a disease characterized by an enduring predisposition to generate epileptic seizures (transient symptoms due to abnormal neuronal activity in the brain) and by the neurobiological, cognitive, psychological and social consequences of the condition. Complex partial seizures usually start in a small area of the temporal lobe or frontal lobe of the brain and quickly involve other areas of the brain that affect alertness and awareness. Approximately 2.2 million patients in the United States and 3.1 in Europe and Japan battle epilepsy. Complex partial seizures are the most common type of seizure, representing 35% of all epilepsies.

About Zynerba Pharmaceuticals, Inc.
Zynerba Pharmaceuticals (NASDAQ:ZYNE) is a specialty pharmaceutical company focused on developing and commercializing proprietary next-generation synthetic cannabinoid therapeutics formulated for transdermal delivery. Zynerba is developing therapeutic candidates based on proprietary transdermal technologies that, if successfully developed, may allow sustained, consistent and controlled delivery of therapeutic levels of two cannabinoids: cannabidiol (CBD), a non-psychoactive cannabinoid, and THC. Transdermal delivery has the potential to reduce adverse effects associated with oral dosing. ZYN002, the Company’s CBD Gel, is the first and only synthetic CBD formulated as a patent protected permeation-enhanced gel and is being studied in refractory epilepsy, Fragile X syndrome and osteoarthritis. Zynerba is also developing ZYN001, which utilizes a synthetically manufactured pro-drug of THC in a transdermal patch to deliver THC through the skin and into the bloodstream. ZYN001 will be studied in fibromyalgia and peripheral neuropathic pain. Learn more at www.zynerba.com and follow the Company on Twitter at @ZynerbaPharma.
