Zynerba Pharmaceuticals Announces Phase 3 RECONNECT Trial Design for Zygel™ in Fragile X Syndrome
- Confirmatory pivotal trial expected to be initiated in the third quarter of 2021 -
- Zynerba to hold conference call today, May 5, 2021 at 5:30 pm ET -
DEVON, Pa., May 5, 2021 – Zynerba Pharmaceuticals, Inc. (Nasdaq: ZYNE), the leader in innovative pharmaceutically-produced transdermal cannabinoid therapies for rare and near-rare neuropsychiatric disorders, today announced the Company has received guidance from the U.S. Food and Drug Administration (FDA) on a confirmatory Phase 3 trial of Zygel in patients with Fragile X syndrome (FXS). The trial, which will be called 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), is designed to evaluate the efficacy and safety of Zygel in children and adolescents with FXS. The study is planned to confirm the positive results observed in a population of responders in the Company’s CONNECT-FX trial, a randomized, double-blind, placebo-controlled trial that assessed the efficacy and safety of Zygel as a treatment for the behavioral symptoms of FXS previously conducted by the Company. The Company believes that the results, if positive, from RECONNECT will be sufficient to support the submission of a New Drug Application for Zygel in patients with FXS.
“Following productive discussions and alignment with the FDA, we believe we have a clear path forward for Zygel in Fragile X syndrome. We are excited to advance Zygel into the RECONNECT trial, a pivotal, multi-national, confirmatory Phase 3 trial in patients with FXS in the third quarter of 2021,” said Armando Anido, Chairman and Chief Executive Officer of Zynerba. “If the results are positive, Zygel could become the first FDA approved treatment option for the significant unmet medical need that affects patients with FXS and their families.”
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-CFXS) 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.

Complete Methylation Results from CONNECT-FX
The Company performed an analysis of the CONNECT-FX population within those patients having complete methylation of their FMR1 gene (n = 137 of 212 in the intent to treat population) to evaluate the effect of Zygel versus placebo. One patient did not have a post-baseline efficacy measure and was therefore not included in the efficacy analysis.
Baseline demographics for patients with complete methylation of the FMR1 gene are shown below. The group is similar to the previously reported full data set of patients and the cohort of patients with ≥90% methylation. The majority of patients were male and the children had a mean age of 9 to 10 years old.

*Statistically significant vs. placebo
**A negative treatment difference demonstrates that Zygel patients improved versus placebo
“The treatment difference versus placebo and p value on the primary endpoint of improvement in the ABC-CFXS Social Avoidance subscale in patients with complete methylation are consistent with the previously reported findings in patients with at least 90% methylation, despite the fact that the study was not powered to evaluate either of these patient populations.” said Dr. Joseph Palumbo, Chief Medical Officer of Zynerba Pharmaceuticals, Inc. “We believe the CONNECT-FX trial was instrumental in advancing our understanding of the science of Fragile X Syndrome. We look forward to leveraging what we learned as we seek to confirm our findings in the RECONNECT trial.”

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 3,600 to 4,000 males and 1 in 4,000 to 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 US, there are about 71,000 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. In neurotypical individuals, there are CGG repeats, but these repeats only occur between 5 and 40 times. As a result, FMRP is manufactured at levels that enable control over behaviors like social avoidance and anxiety. In people with full mutation of the Fragile X gene, the CGG segment is repeated more than 200 times and in most cases causes the FMR1 gene to not function. However, the methylation of the FMR1 gene also plays a role in determining functionality of the gene. For patients with complete (100%) methylation, the FMR1 gene is silenced, therefore, no FMRP is produced, and the systems and processes that are expected to be affected by FMRP become dysregulated.
