Myrtelle Inc. Reports Encouraging Results in Gene Therapy for Canavan Disease

Myrtelle Inc., a trailblazing company in the field of gene therapy focused on neurodegenerative diseases, will soon present its noteworthy interim findings from a Phase 1/2 clinical trial for its investigational gene therapy, rAAV-Olig001-ASPA (MYR-101). The presentation is set for the 2025 Cell and Gene Meeting on the Mesa, a significant event organized by the Alliance for Regenerative Medicine in Phoenix, Arizona, where insights on advancing therapeutic strategies are anticipated.

Canavan disease is a severe genetic disorder caused by mutations affecting the ASPA gene, leading to a deficiency in the enzyme aspartoacylase, essential for myelin production in brain cells. Children with Canavan disease typically appear normal at birth but show signs of the disease, such as poor head control and an enlarged head circumference, within the first few months of life. The disease progresses to severe physical and cognitive disabilities, often leading to life-threatening complications by the age of ten. Currently, no curative treatments exist; only palliative care is available, making developments like those from Myrtelle critical.

Key Findings from the Clinical Trial

The clinical trial results, recently highlighted in Nature Medicine, showcase several encouraging outcomes from the MYR-101 gene therapy treatment:
1. Safety Profile: The therapy demonstrated a favorable and well-tolerated safety profile, with no significant adverse events attributed to the treatment.
2. Biological Activity: Notable reductions in N-acetylaspartate (NAA) levels in the cerebrospinal fluid were observed, indicating the restoration of ASPA enzyme activity.
3. Myelination Evidence: Increases in brain myelin volume as measured by Synthetic MRI (SyMRI) suggest remyelination, supporting the therapeutic benefits of MYR-101.
4. Functional Improvements: Participants exhibited measurable developmental advancements compared to historical controls, showing an overall positive trend in functional gains.
5. Durable Outcomes: Long-term follow-up data indicate promising results and durability of therapeutic effects.

Dr. Michael Muhonen, M.D., Co-Chief Medical Officer at Myrtelle, expressed optimism regarding the findings, stating, "These data represent a major step forward for children and families affected by Canavan disease. For the first time, we’re seeing clear biological and functional evidence that gene therapy targeting oligodendrocytes can directly address the core pathology of this disease."

Regulatory Highlights

Myrtelle's MYR-101 has achieved significant recognition from regulatory bodies. The U.S. FDA selected it for the START pilot program, which is designed to expedite the development of clinical trials for rare disease therapeutics. This places MYR-101 in an elite category among gene therapies, involving enhanced collaboration with the FDA for advancing its development.

Additionally, MYR-101 has received multiple designations:

• - Regenerative Medicine Advanced Therapy (RMAT) designation from the FDA.
• - Orphan Drug, Rare Pediatric Disease, and Fast Track designations by the FDA.
• - Orphan Drug Designation and Advanced Therapy Medicinal Product (ATMP) classification awarded by the EMA.
• - Innovative Licensing and Access Pathway (ILAP) designation from the MHRA in the UK.

About Canavan Disease and the Future

The urgency behind addressing Canavan disease is underscored by the debilitating nature of the disorder. As indications of effective treatments emerge from ongoing trials, hope is rekindled for those affected and their families. Myrtelle's proprietary platform and strategic collaborations, including an exclusive licensing agreement with Pfizer Inc. concerning the Canavan disease program, reinforce the company’s commitment to creating transformative therapies in this challenging field.

As the presentation at the 2025 Cell and Gene Meeting on the Mesa approaches, the biotechnology community eagerly anticipates more detailed findings on MYR-101, which could potentially reshape the therapeutic landscape for Canavan disease. Myrtelle remains at the forefront, striving to change the narrative for numerous families facing this devastating disease.
