RECONNECT initial screening visits are being adversely impacted by environmental factors, such as the “Tripledemic” (high rates of RSV, influenza and COVID-19); topline results now expected first half of 2024

Cash runway extended to mid-year 2024 due to


prioritization of resources on the completion of the RECONNECT trial

DEVON, Pa., Dec. 21, 2022 (GLOBE NEWSWIRE) —

Zynerba Pharmaceuticals

, Inc. (Nasdaq: ZYNE), the leader in innovative pharmaceutically-produced transdermal cannabinoid therapies for orphan neuropsychiatric disorders, today announced that the Company is revising its target for announcing topline results from the pivotal Phase 3 RECONNECT trial of Zygel in Fragile X syndrome (FXS). The Company now expects topline results in the first half of 2024, rather than the second half of 2023.

The impact of environmental factors including unusually high rates of RSV (respiratory syncytial virus) and influenza and the continued impact of COVID-19 among children, adolescents, family members, and investigational center personnel, has resulted in higher than expected cancellations of initial screening visits at the investigational centers which has led to slower than anticipated enrollment. Despite these issues, clinical investigators at the 27 sites in the U.S., Australia, the UK and Ireland remain committed to completing the trial.

“Though we are still striving to report topline results by the end of 2023, when we look at the current and projected impact of the Tripledemic, we believe that the first half of 2024 is a more reasonable timeframe to have topline results from RECONNECT,” said Armando Anido, Chairman and Chief Executive Officer of Zynerba. “We have also prioritized our corporate business plans to focus almost exclusively on completing RECONNECT and now expect we have cash into mid-year 2024.”

About Zygel

Zygel is the first and only pharmaceutically-manufactured cannabidiol 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 cannabidiol may modulate the endocannabinoid system and improve certain behavioral symptoms associated with neuropsychiatric conditions. Zygel is an investigational drug product in development for the potential treatment of behavioral symptoms associated with Fragile X syndrome (FXS), 22q11.2 deletion syndrome (22q) and autism spectrum disorder (ASD). The Company has received orphan drug designation for cannabidiol, the active ingredient in Zygel, from the FDA and the European Commission in the treatment of FXS and the treatment of 22q. Additionally, Zygel has been designated a Fast Track development program for treatment of behavioral symptoms of FXS.

About RECONNECT

RECONNECT is a randomized, double-blind, placebo-controlled, multiple-center efficacy and safety trial of Zygel administered as a transdermal gel to children and adolescents ages 3 through 17 with Fragile X syndrome. For more information regarding participation visit

About Fragile X Syndrome (FXS)

Fragile X syndrome is a rare genetic developmental disability that is the leading known cause of both inherited intellectual disability and autism spectrum disorder, affecting 1 in 4,000 males and 1 in 6,000 females. It is the most common inherited intellectual disability in males and a significant cause of intellectual disability in females, and the leading genetic cause of autism spectrum disorder (ASD). The disorder negatively affects synaptic function, plasticity and neuronal connections, and results in a spectrum of intellectual disabilities and behavioral symptoms, such as social avoidance and irritability. In the U.S., there are about 78,000 people suffering with FXS, approximately 60% of whom have complete methylation of the

FMR1

gene.

FXS is caused by a mutation in

FMR1

, a gene which modulates a number of systems, including important effects on the endocannabinoid system, and most critically, codes for a protein called FMRP. This protein helps regulate the production of other proteins and plays a role in the development of synapses, which are critical for relaying nerve impulses, and in regulating synaptic plasticity. The

FMR1

mutation manifests as multiple repeats of a DNA segment, known as the CGG triplet repeat. In most neurotypical people, the

FMR1

gene correctly codes for the FMRP protein. As a result, FMRP is produced at levels that enable control over behaviors like social avoidance and anxiety. In people with full mutation of the

FMR1

gene, the CGG segment is repeated more than 200 times, and in most cases causes the gene to not function. Methylation of the

FMR1

gene also plays a role in determining functionality of the gene. For patients with complete methylation, no FMRP is produced. With no FMRP, the systems and processes that are modulated by FMRP become dysregulated.
