Zynerba Pharmaceuticals Provides Regulatory Update on Zygel™ in Fragile X Syndrome

 

- Single Trial to be Conducted in Patients with Fragile X Syndrome to Confirm Positive Results Seen in the Population of Responders in the CONNECT-FX Trial -

 

- Conference Call and Webcast Today, December 17, 2020 at 8:30 am ET -

 

DEVON, Pa., December 17, 2020 – Zynerba Pharmaceuticals, Inc. (NASDAQ:ZYNE), the leader in innovative pharmaceutically-produced transdermal cannabinoid therapies for rare and near-rare neuropsychiatric disorders, today provided an update on its meeting with the U.S. Food and Drug Administration (FDA) regarding its Fragile X syndrome (FXS) program. The Company plans to conduct a double-blind, placebo-controlled pivotal trial 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. In the first half of 2021, Zynerba will review the trial design and protocol for the new trial through a Type C meeting with the FDA and expects to initiate the pivotal trial before the end of 2021. Zynerba believes that positive results from this confirmatory trial would be sufficient to support the submission of a New Drug Application (NDA) for Zygel™ in FXS.

 

“We believe that Zygel has the potential to meaningfully relieve the behavioral symptoms of the most impacted individuals with Fragile X syndrome. We are committed to bringing this important therapy to patients and their families within the Fragile X community,” said Armando Anido, Chairman and Chief Executive Officer of Zynerba. “We are thankful for our ongoing constructive dialogue with the FDA on our path forward to NDA submission. Completing the development of Zygel in FXS and preparing for a successful launch will be the primary focus of the Company.”

 

“The results reported in the analysis of children with a highly methylated FMR1 gene are a source of considerable hope for the patients and their families who are impacted by Fragile X syndrome,” said Linda Sorensen, Executive Director of the National Fragile X Foundation (NFXF). “Zynerba has been an important partner to the families of children with Fragile X. We thank them for their continued dedication and commitment to bringing an FDA-approved treatment to our families and look forward to helping with the recruitment of patients for this study.”

 

The Company’s development plan for Zygel in other indications includes the following:

 

·Developmental and epileptic encephalopathies (DEE): Evaluation of potential target indications is ongoing, and Zynerba now expects to finalize target syndrome selection in 2021 in one or more DEE syndromes.

 

 

 

 

·22q11.2 deletion syndrome (22q): Zynerba expects to resume recruitment for the 14-week open label Phase 2 INSPIRE trial in children and adolescents with genetically confirmed 22q once COVID-19-related restrictions in Australia are eased. After recruitment has resumed, the Company will be able to provide a timeframe for completion of this trial.

 

·Autism spectrum disorder (ASD): In the first half of 2021, Zynerba intends to discuss 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 with the FDA to determine the regulatory path forward.

 

Financial Impact on Cash

 

The Company expects that its cash runway will extend into the beginning of 2023 as a result of these changes to its development plans.

Zynerba management will host a live conference call and webcast today at 8:30 am Eastern Time to discuss the recent FDA meeting and the regulatory pathway for Zygel in FXS.

6 • Rare genetic developmental disability • Leading known cause of both inherited intellectual disability and ASD • No approved drugs indicated for FXS • Symptoms linked to deficiencies in the endocannabinoid system (ECS) • Mutation impacts FMR1 gene and causes ECS dysregulation, causing core cognitive, social, and behavioral symptoms of FXS • Easily identified mutation manifests as multiple CGG repeats in FMR1 (full mutation = >200 repeats) • U.S. patents provide IP protection to 2038 • FMR1 gene codes for production of FMRP* which is vital to synapse development • Methylation of FMR1 also plays a role in determining functionality of the gene • When methylation of FMR1 silences the gene, no FMRP is produced: Systems and processes affected by FMRP become dysregulated • These patients are generally the most severely impacted by the disorder: lower IQ, more impacted behaviors • ~60% of patients are believed to fall into this category Fragile X Syndrome (FXS) *FMR Protein; RNA - binding protein that helps regulate synaptic development and plasticity Role of FMR1 Methylation FXS FXS is routinely diagnosed by assessing (1) CGG repeats and (2) methylation status ~40K U.S. patients ≥90% FMR1 methylation ~70K U.S. patients with full mutation FXS

The Path Forward For Zygel in FXS 11 • Zynerba plans to conduct a single double blind, placebo controlled pivotal trial in patients with a highly methylated FMR1 gene to confirm results seen in CONNECT - FX responders • If results are positive, we believe this trial will be sufficient to support an NDA submission • Primary endpoint will be the Social Avoidance subscale of the ABC - C FXS • Trial design and protocol development ongoing for planned confirmatory trial in CONNECT - FX responder population • Type C meeting with FDA expected in 1H21 to review trial design and protocol • Initiation of confirmatory trial is expected before the end of 2021 and timing will be clarified after Type C meeting Next Steps Regulatory Update
