Zynerba Pharmaceuticals Initiates Phase 2 Trial of Zygel™ in Autism Spectrum Disorder

– Topline Data from BRIGHT Study Expected in the First Half 2020-

– Company Selects Zygel™ as Brand Name for ZYN002 CBD Transdermal Gel –

DEVON, Pa., March 7, 2019 – Zynerba Pharmaceuticals, Inc. (NASDAQ:ZYNE), the leader in innovative pharmaceutically-produced transdermal cannabinoid therapies for rare and near-rare neuropsychiatric disorders, today announced that it has initiated the Phase 2 BRIGHT (An Open-Label Tolerability and Efficacy Study of ZYN002 Administered as a Transdermal Gel to Children and Adolescents with Autism Spectrum Disorder) trial. The trial will assess the safety, tolerability and efficacy of Zygel (previously referred to as ZYN002) for the treatment of child and adolescent patients with Autism Spectrum Disorder (ASD). The Company expects to present topline data from this study in the first half of 2020.

“Autism spectrum disorder can have a devastating impact on a child and their family,” said Armando Anido, Chairman and Chief Executive Officer of Zynerba. “The medical need is significant and unmet despite high awareness and advocacy efforts. Though there has been an accelerating rate of diagnosis, to date there are only two FDA approved products indicated for the treatment of ASD symptoms. Both have significant side effect profiles, and neither have been approved to address the key symptoms of social impairment and anxiety. We are excited to initiate the BRIGHT trial evaluating the role of Zygel in ASD and are hopeful that Zygel may improve some of the core social and behavioral symptoms of ASD. We look forward to presenting topline data in the first half of 2020.”

The 14-week BRIGHT trial is an open-label multi-dose Phase 2 clinical trial designed to evaluate the efficacy and safety of Zygel in approximately 36 children and adolescents (ages four through 17) with ASD as confirmed by DSM-5 diagnostic criteria for ASD. Enrolled patients will receive weight-based initial doses of 250 mg daily or 500 mg daily of Zygel. The efficacy assessments include the Aberrant Behavior Checklist, Parent Rated Anxiety Scale – Autism Spectrum Disorder, Autism Impact Measure, and Clinical Global Impression – Severity and Improvement.

About Autism Spectrum Disorder (ASD)
Autism Spectrum Disorder is a developmental disorder that affects communication and behavior in approximately one million pediatric and adolescent patients between the ages of five and 17 in the U.S. It refers to a range of conditions characterized by anxiety, repetitive patterns of behavior, impairments in social communication including verbal and non-verbal communication, and deficits in developing and maintaining relationships. Although autism can be diagnosed at any age, it is said to be a “developmental disorder” because symptoms generally appear in the first two years of life. Research suggests that genes can act together with influences from the environment to affect development in ways that lead to ASD.

About Zygel™
Zygel (CBD gel) is the first and only pharmaceutically-manufactured CBD formulated as a patent-protected permeation-enhanced clear gel, designed to provide controlled drug delivery into the bloodstream transdermally (i.e. through the skin). Recent studies suggest that ASD may be associated with a disruption in the endocannabinoid (EC) system. Clinical and anecdotal data suggest that CBD may modulate the EC system and improve certain core social and behavioral autism-related symptoms, including social avoidance and anxiety.

Enrollment is ongoing in a multi-national, randomized, double blind placebo controlled Clinical study of Cannabidiol (CBD) in Children and Adolescents with Fragile X (CONNECT-FX), a pivotal clinical trial of ZYN002 in FXS (https://www.connectfxtrial.com/); topline data from CONNECT-FX are expected in the second half of 2019. Additionally, Zynerba expects to topline data from its Phase 2 Open Label Study to Assess the Safety and Efficacy of ZYN002 Administered as a Transdermal Gel to Children and Adolescents with Developmental and Epileptic Encephalopathy (BELIEVE 1) clinical trial in the third quarter of 2019.
