Zynerba Pharmaceuticals Announces Completion of Enrollment in Phase 2 Trial of Zygel™ in 22q11.2 Deletion Syndrome
Topline data from Phase 2 INSPIRE trial expected mid-year 2022
DEVON, Pa., Feb. 28, 2022 (GLOBE NEWSWIRE) -- Zynerba Pharmaceuticals, Inc. (Nasdaq: ZYNE), the leader in innovative pharmaceutically-produced transdermal cannabinoid therapies for rare and near-rare neuropsychiatric disorders, today announced the completion of enrollment for the 14-week Phase 2 INSPIRE (Assessing the Impact of Zygel [Transdermal CBD Gel] on Pediatric Behavioral and Emotional Symptoms of 22q11.2 Deletion Syndrome) trial of Zygel in the treatment of behavioral symptoms of 22q11.2 deletion syndrome (22q) in children and adolescents. The Company continues to expect topline data from this trial mid-year 2022. The Company has previously received orphan drug designation for Zygel in 22q from the FDA.
“The completion of enrollment in our INSPIRE trial is an important step forward in advancing Zygel as a potential new treatment option for patients suffering from 22q,” said Armando Anido, Chairman and Chief Executive Officer of Zynerba. “Pending results from the INSPIRE trial and subsequent discussion with the FDA on the regulatory path forward, we plan to advance our clinical development program in 22q with Zygel. We are thankful for the combined efforts of our researchers, investigators and the patient and caregiver community.”
The 14-week INSPIRE trial is an open-label, multi-dose, Phase 2 clinical trial designed to evaluate the efficacy and safety of Zygel in children and adolescents (ages six through 17) with genetically-confirmed 22q. Enrolled patients receive weight-based doses of 250 mg daily or 500 mg daily of Zygel. The efficacy assessments include the Aberrant Behavior Checklist-Community (ABC-C), the Anxiety, Depression and Mood Scale (ADAMS), the Qualitative Caregiver Reported Behavioral Problem Survey, and Clinical Global Impression – Severity and Improvement. A total of 20 patients have been enrolled in the INSPIRE trial.
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), autism spectrum disorder (ASD), and 22q11.2 deletion syndrome (22q). Zygel has been granted orphan drug designation by the FDA in the treatment of FXS and 22q. Additionally, the FDA has designated Zygel a Fast Track development program for treatment of behavioral symptoms of FXS.
About 22q11.2 Deletion Syndrome (22q)
As the second most common chromosomal disorder after Down syndrome, 22q is caused by a small missing piece of the 22nd chromosome. The deletion occurs near the middle of the chromosome at a location designated q11.2. It is considered a mid-line condition, with physical symptoms including characteristic palate abnormalities, heart defects, immune dysfunction, and esophageal/GI issues, as well as debilitating neuropsychiatric and behavioral challenges. Anxiety is among the most common neuropsychiatric symptoms of 22q and researchers have found that for children with 22q, anxiety is linked to poorer adaptive behaviors such as self-care and communication skills that affect daily life. Children with 22q also experience withdrawn behavior, ADHD, cognitive impairment, and autism spectrum disorder that affect communication and social interaction. Later in life, they are at an increased risk of developing mental illnesses such as schizophrenia. It is estimated that 22q has a prevalence rate of approximately one in 4,000 people in the U.S.1,2, suggesting that there are approximately 83,000 people living with 22q in the U.S.
