• On track to initiate RECONNECT, a confirmatory pivotal trial of Zygel™ in patients with FXS, in the third quarter of 2021
• Positive feedback from FDA clarifies potential path forward in ASD
• Cash runway well into the first half of 2024; $85.8 million at June 30, 2021

Zynerba Pharmaceuticals, Inc. (Nasdaq: ZYNE), the leader in innovative pharmaceutically-produced transdermal cannabinoid therapies for rare and near-rare neuropsychiatric disorders, today reported financial results for the second quarter ended June 30, 2021, and provided an overview of recent operational highlights and a pipeline update.

“We continue to make progress across our portfolio, particularly in FXS in which our confirmatory pivotal Phase 3 trial, RECONNECT, is expected to start in the third quarter of 2021,” said Armando Anido, Chairman and Chief Executive Officer of Zynerba. “Following a positive meeting with the FDA on our development program in autism spectrum disorder (ASD), we are evaluating and prioritizing our development options for ASD, 22q and developmental and epileptic encephalopathies and we expect to provide guidance on the path forward in each of these indications by the end of 2021.”

Second Quarter 2021 and Recent Highlights and Zygel Pipeline Update

Zygel in Fragile X Syndrome (FXS)

• Zynerba expects to initiate RECONNECT (A Randomized, Double-Blind, Placebo-Controlled, Multiple-Center, Efficacy and Safety Study of ZYN002 Administered as a Transdermal Gel to Children and Adolescents with Fragile X Syndrome), a pivotal, multi-national confirmatory Phase 3 trial of Zygel in children and adolescents with FXS, in the third quarter of 2021. The trial is designed to confirm the positive results observed in a population of responders in the Company’s previously conducted CONNECT-FX trial. (Press release)
• The RECONNECT trial will be an 18-week trial which will enroll approximately 200 children and adolescents of which approximately 160 patients will have complete (100%) methylation of their FMR1 gene and approximately 40 patients will have partial methylation of their FMR1 gene. The primary endpoint for the trial will be the change in the Aberrant Behavior Checklist-Community FXS Specific (ABC-C_FXS) Social Avoidance subscale in patients who have complete methylation of their FMR1 gene. All patients, including the cohort of partially methylated patients, will be included in a key secondary endpoint analysis. The Company believes that the results from RECONNECT, if positive, will be sufficient to support the submission of a New Drug Application for Zygel in patients with FXS.
• Presented data at the International Society for Pharmacoeconomic and Outcomes Research (ISPOR) Virtual 2021 Conference demonstrating the ABC-C_FXS subscales capture behaviors that are impactful and understandable to caregivers of children with FXS and are fit for purpose for measuring clinical trial endpoints in FXS. (Press release)

Zygel in Autism Spectrum Disorder (ASD)

• In the first half of 2021, Zynerba discussed data supporting the potential efficacy of Zygel in ASD, including the results of the Phase 2 BRIGHT trial, with the U.S. Food and Drug Administration (FDA) to determine the regulatory path forward. The guidance from the FDA included agreement on utilizing the irritability subscale of the Aberrant Behavior Checklist – Community (ABC-C) as the primary endpoint to support an indication for the treatment of irritability in ASD. This is the same primary endpoint utilized in the previously completed BRIGHT open label Phase 2 trial.
• Presented data at the 2021 American Society of Clinical Psychopharmacology (ASCP) Annual Meeting demonstrating that Zygel may provide important clinical promise across a spectrum of endpoints, including, behavior, seizure reduction and sleep in children with ASD, children with developmental epileptic encephalopathies (DEE) with comorbid ASD, and children with FXS with comorbid ASD. These previously disclosed data are from two open-label Phase 2 trials and one double-blind placebo-controlled trial when added to standard of care in children and adolescents. (Press release)

Zygel in 22q11.2 Deletion Syndrome (22q)

• Despite constantly changing COVID-19-related restrictions in Australia, the Company has resumed screening of patients for the 14-week open label Phase 2 INSPIRE trial in children and adolescents with genetically confirmed 22q. Once enrollment is complete, a timeframe for disclosing topline results of the trial will be provided.

Zygel in Developmental and Epileptic Encephalopathies (DEE)

• Zynerba is conducting an observational trial that will help finalize target syndrome selection in one or more DEE syndromes in 2021. Due to the heterogeneity of patients who fall under the DEE umbrella, the FDA suggested the company pursue individual syndromes rather than considering DEE as a single disorder or condition (Press release).
• Presented data at the Associated Professional Sleep Societies SLEEP 2021 Annual Meeting demonstrating in an open-label Phase 2 trial with patients with DEE, treatment with Zygel was associated with improved sleep in children with clinically significant sleep disorders at baseline. Furthermore, the children with both DEE and ASD appeared to show more wide-ranging benefits on sleep compared to those with DEE alone. The Company believes that because epilepsy and sleep disorders have a bidirectional relationship and co-occur in individuals with ASD, improvements in sleep may result in better seizure control and behavior in these medically fragile children with DEE.

Second Quarter 2021 Financial Results

Research and development expenses were $5.5 million for the second quarter of 2021, including stock-based compensation of $1.0 million. General and administrative expenses were $4.4 million in the second quarter of 2021, including stock-based compensation expense of $0.9 million. The net loss for the second quarter of 2021 was $10.0 million, with basic and diluted loss per share of $(0.25).
