Team prepares for commercialization bolstered by START Program and regulatory recognition
NEW YORK, NY, USA I July 8, 2025 I
Myrtelle Inc. (“Myrtelle” or the “Company”), a pioneering clinical-stage gene therapy company dedicated to revolutionizing treatment for neurodegenerative diseases, today announced the official launch of commercial-stage manufacturing for its first-in-class oligotrophic recombinant adeno-associated virus (rAAV) gene therapy product, developed specifically for Canavan disease (CD). This landmark achievement propels Myrtelle’s therapy closer to market and patients who urgently need it.
The manufacturing program is being executed in strategic partnership with two global leaders in gene therapy infrastructure:
Charles River
and
Viralgen Vector Core (a subsidiary of AskBio Inc.)
. Together, the trio is setting a new standard in viral vector innovation, combining Myrtelle’s proprietary science with Charles River’s GMP plasmid manufacturing and analytical excellence at their CDMO center of excellence in Keele, UK, and Viralgen’s cutting-edge GMP vector production at their world-class facility in San Sebastián, Spain.
Myrtelle Launches Commercial-Stage Manufacturing for Gene Therapy Product Targeting Canavan Disease
“This is a transformative moment for Myrtelle and the entire Canavan disease community,”
said
Adrian Stecyk, Chief Executive Officer of Myrtelle
. “Initiating commercial manufacturing represents the culmination of our bold vision—to translate deep scientific innovation into real-world therapies. With Charles River and Viralgen as our partners, we are poised to deliver a life-changing treatment with precision, scalability, and speed.”
At the heart of this initiative is
MYR-101
, Myrtelle’s pioneering rAAV-Olig001-ASPA gene therapy. Engineered with a unique tropism for oligodendrocytes—the myelin-producing cells compromised in Canavan disease—MYR-101 is designed to directly address the genetic root of the disorder by restoring ASPA enzyme function and supporting normal brain development. This targeted approach has the potential not only to halt disease progression but to enable true neural repair through remyelination.
“When every day, every hour, every minute makes a difference in saving lives, the Charles River team is excited and privileged to continue to support Myrtelle at this pivotal stage,”
said
Kerstin Dolph, Corporate Senior Vice President of Global Manufacturing at Charles River
. “Myrtelle’s groundbreaking program exemplifies the progress gene therapy has made from concept toward commercial reality, and we’re proud to be part of that journey, bringing hope to the patients and families affected by Canavan disease.”
“Our mission at Viralgen is to transform people’s lives through our manufacturing science,”
said
Jimmy Vanhove, Chief Executive Officer at Viralgen
. “Myrtelle’s work in Canavan disease is extraordinary, and we are honored to contribute our expertise and advance GMP production to help make this therapy a reality.”
Myrtelle’s gene therapy program continues to gain momentum on multiple fronts. The Company remains on track to finalize regulatory filings and prepare for commercial launch, pending approvals. MYR-101 was selected as one of just four programs to participate in the FDA’s
Support for Clinical Trials Advancing Rare Disease Therapeutics (START) Pilot Program
, a groundbreaking initiative to accelerate development of treatments for serious rare diseases by enhancing regulatory communication and flexibility.
The company’s progress has also been recognized globally with
multiple key designations
awarded to rAAV-Olig001-ASPA, including:
With manufacturing now underway in preparation for commercialization, Myrtelle is accelerating toward its goal of delivering the
first approved therapy for Canavan disease
, opening a new chapter in the treatment of rare neurodegenerative conditions—and offering a profound message of hope to patients and families around the world.

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.
