Myrtelle to Present Clinical Data and Regulatory Progress for MYR-101 Gene Therapy Program at ASGCT 2026

NEW YORK, May 11, 2026 /PRNewswire/ -- Myrtelle, Inc., a clinical-stage gene therapy company selected by the FDA for the START Pilot Program and focused on developing treatments for neurodegenerative diseases, today announced its participation in the upcoming American Society of Gene & Cell Therapy (ASGCT) Annual Meeting where clinical trial data from its first-in-class, oligodendrocyte targeting investigational gene therapy program for Canavan disease will be presented.

Dr. Paola Leone, an internationally recognized leader in Canavan disease research and scientific adviser to Myrtelle, has been invited to present in the session "Beyond neurons: Glial-targeted gene and cell therapies for neurologic and ophthalmic diseases," organized by the Neurologic and Ophthalmic Cell and Gene Therapy Committee, on Tuesday, May 12th, from 3:30 p.m. to 5:00 p.m. ET. Her presentation, "AAV Mediated Gene Therapy for Canavan Disease (Clinical Trial)," will focus on clinical data from Myrtelle's ongoing study.

"We're honored to present encouraging data from children treated to date at ASGCT, demonstrating signals of therapeutic benefit and meaningful clinical improvement, while contributing to the advancement of innovative gene therapy for Canavan disease," said Dr. Paola Leone.

In addition, Adrian Stecyk, Chief Executive Officer of Myrtelle, will serve as a guest presenter at a lunchtime sponsored symposium on Wednesday, May 13th, hosted by Viralgen, Myrtelle's commercial manufacturing partner for MYR-101, the company's first-in-class gene therapy candidate for Canavan disease.

The presentation will highlight Myrtelle and Viralgen's collaboration, the status of Myrtelle's participation in the START Pilot Program, and the company's regulatory path toward BLA submission, including key data highlights from the gene therapy study.

"We are pleased to continue advancing MYR-101 in collaboration with Viralgen and to share our progress with the ASGCT community," said Adrian Stecyk.

About Canavan Disease
Canavan disease (CD) is a fatal childhood genetic brain disease caused by mutations in the ASPA gene (ASPA) which prevent the normal expression of aspartoacylase, a critical enzyme produced in oligodendrocytes. The lack of normal aspartoacylase expression negatively impacts brain bioenergetics and development, including myelin production. Patients with CD are impacted at birth but may appear normal until several months old when symptoms begin to develop. Poor head control, abnormally large head size, difficulty in eye tracking, excessive irritability, severely diminished muscle tone, and delays in reaching motor milestones, such as rolling, sitting, and walking, are the typical initial manifestations of CD. As the disease progresses, seizures, spasticity, difficulties in swallowing, and overall muscle deterioration emerge with most affected children developing life-threatening complications by approximately 10 years of age. Currently, there are no cures for CD, and only palliative treatments are available.
