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 fourth quarter and full year ended December 31, 2020, and provided an overview of recent operational highlights and a pipeline update.

“We expect to make significant progress in 2021 on all four indications for which we are developing Zygel, including initiating a pivotal trial in patients with Fragile X syndrome who have a highly methylated FMR1 gene to confirm the positive results in this population of responders in the CONNECT-FX trial,” said Armando Anido, Chairman and Chief Executive Officer of Zynerba. “Screening in the INSPIRE trial of patients with 22q11.2 deletion syndrome has resumed now that COVID-19 restrictions in Australia have begun to ease. Once enrollment is complete we will update our expectation on when we will see topline results for this trial.”

Operational Highlights and Pipeline Update

Zygel™ in Fragile X Syndrome (FXS)

• Zynerba expects to initiate a single double-blind, placebo-controlled pivotal trial before the end of 2021 in patients with FXS who have a highly methylated FMR1 gene to confirm the positive results observed in this population of responders in the CONNECT-FX trial. The Company believes that positive results from this confirmatory pivotal trial will be sufficient to support the submission of a New Drug Application for Zygel in FXS. (Press release)
• Zynerba will review the trial design and protocol for the new confirmatory pivotal trial through a Type C meeting with the U.S. Food and Drug Administration (FDA) in the first half of 2021.

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

• The Company has initiated a second clinical site in Australia for the 14-week open label Phase 2 INSPIRE trial in children and adolescents with genetically confirmed 22q.
• As the COVID-19-related restrictions in Australia are easing, the Company has resumed screening of patients for this trial. Once enrollment is complete, a timeframe for disclosing topline results of the trial will be provided. In September 2020, the Company was granted orphan drug designation from the FDA for the use of cannabidiol for the treatment of 22q.

Zygel in Autism Spectrum Disorder (ASD)

• In the first half of 2021, Zynerba intends to discuss with the FDA data supporting the potential efficacy of Zygel in ASD, including the results of the Phase 2 BRIGHT trial in children and adolescents with moderate to severe ASD, to determine the regulatory path forward.

Zygel in Developmental and Epileptic Encephalopathies (DEE)

• Zynerba expects to conduct an observational trial that will help finalize target syndrome selection in one or more DEE syndromes in 2021.
  
  Zynerba concluded its iterative discussions with the FDA utilizing their ‘Written Response Only’ (WRO) meeting format regarding the clinical pathway for Zygel in DEE during which the FDA expressed support for a development program which would evaluate the treatment of focal-impaired awareness seizures (FIAS) and tonic-clonic seizures (TCS). Due to the heterogeneity of patients who fall under the DEE umbrella, Zynerba will pursue individual syndromes rather than considering DEE as a single disorder or condition (Press release). The Company expects to conduct an observational trial that will help finalize target syndrome selection in one or more DEE syndromes by the end of 2021.

• New efficacy data presented at the 2020 annual meeting of the American Epilepsy Society show strong evidence of seizure reduction.
  
  The new efficacy data from the Phase 2 BELIEVE trial (Open Label Study to Assess the Safety and Efficacy of Zygel Administered as a Transdermal Gel to Children and Adolescents with DEE) describe strong evidence of seizure reduction over 12 months of treatment, including a 73% median reduction from baseline in FIAS and TCS seizure frequency at month 12. Furthermore, in the subgroup of patients with ASD, Zygel demonstrated meaningful reductions in FIAS and TCS seizures, with most children reaching either the 35% or 50% responder threshold by month three and month six, respectively.
  
  The data also show that Zygel improved the profound sleep disturbance experienced by patients with DEE who were enrolled in the trial (Press release).

Fourth Quarter and Full Year 2020 Financial Results

Research and development expenses were $5.6 million for the fourth quarter of 2020, including stock-based compensation of $0.6 million. General and administrative expenses were $4.6 million in the fourth quarter of 2020, including stock-based compensation expense of $0.6 million. The net loss for the fourth quarter of 2020 was $9.6 million with basic and diluted loss per share of $(0.33).

Research and development expenses were $35.7 million for full year 2020, including stock-based compensation of $2.2 million. General and administrative expenses were $16.4 million for full year 2020, including stock-based compensation expense of $3.0 million. The net loss for the full year 2020 was $51.3 million with basic and diluted net loss per share of $(1.90).

Financial Outlook

As of December 31, 2020, cash and cash equivalents were $59.2 million, compared to $70.1 million as of December 31, 2019. In August 2019, we entered into a Controlled Equity Offering Sales Agreement^SM, or the 2019 Sales Agreement, with Cantor Fitzgerald & Co., Canaccord Genuity, LLC, H.C. Wainwright & Co. LLC and Ladenburg Thalmann & Co. Inc., as sales agents pursuant to which we may sell, from time to time, up to $75.0 million of our common stock. In the fourth quarter of 2020, we sold and issued 558,089 shares of our common stock under the 2019 Sales Agreement in the open market resulting in gross proceeds of $1.9 million and net proceeds of $1.9 million, after deducting commissions and offering expenses. From January 1, 2021 through February 9, 2021, we have sold and issued 10,244,326 shares of our common stock under the 2019 Sales Agreement in the open market resulting in gross proceeds of $43.2 million and net proceeds of $42.2 million, after deducting commissions and offering expenses. As of February 9, 2021, we have utilized the entire $75 million authorized under the 2019 Sales Agreement, which was terminated pursuant to its terms.

Management believes that cash and cash equivalents, including the $42.2 million in net proceeds from issuances between January 1 and February 9, 2021 under the 2019 Sales Agreement, are sufficient to fund operations and capital requirements well into the first half of 2024.
