Innovative Collaboration Aims to Advance Gene Therapy for Rett Syndrome

Apertura Gene Therapy Partners with Rett Syndrome Research Trust

Apertura Gene Therapy, a pioneering entity in biotechnology specializing in gene therapy solutions, is collaborating with the Rett Syndrome Research Trust (RSRT) to embark on an innovative journey to combat Rett Syndrome. This progressive partnership revolves around licensing Apertura's groundbreaking human transferrin receptor 1 capsid (TfR1 CapX). Together, they aim to enhance genetic medicine methods for treating Rett Syndrome, a rare genetic neurological disorder predominantly affecting females due to mutations in the MECP2 gene.

The Significance of TfR1 CapX in Gene Therapy

Apertura's TfR1 CapX is an advanced adeno-associated virus (AAV) capsid specially designed to bind to the transferrin receptor 1 (TfR1). This unique capability allows for efficient delivery of genetic therapies across the blood-brain barrier (BBB). The significance of TfR1 as a BBB-crossing receptor is underscored by its consistent expression across various stages of life and in the presence of neurological diseases. These properties make it a prime target for central nervous system (CNS) pursuit in conditions like Rett syndrome.

Preclinical Research Shows Promising Results

Developed by Dr. Ben Deverman, the Director of Vector Engineering at the Broad Institute, the TfR1 CapX has demonstrated remarkable CNS selectivity during preclinical tests, efficiently achieving over 50% neuronal and 90% astrocyte transduction across various brain regions. Given that Rett syndrome diffusely impacts the brain, achieving broader cellular transduction is likely to lead to significant symptomatic relief for patients.

RSRT's Commitment to Advancing Treatments

Monica Coenraads, Founder and CEO of RSRT, expressed profound enthusiasm about integrating this innovative capsid into their gene-editing initiatives, which aligns with their mission to accelerate development in Rett syndrome therapies. The integration of TfR1 CapX reflects a substantial advancement in the quest for wider distributable gene therapies for this condition.

Collaborative Efforts Towards Development

In an impressive display of collective effort, last year RSRT spearheaded the launch of the MECP2 Editing Consortium, which includes six research laboratories focusing on next-generation treatments for Rett syndrome. Utilization of the Apertura capsid for delivering therapeutic agents non-invasively across the brain forms a critical component of the consortium's goals.

The Positive Impact on Patients and Families

According to Diego Garzón, PhD and Vice President of Corporate Development at Apertura Gene Therapy, their commitment to addressing the urgent need for powerful yet less invasive treatments can significantly transform the experiences of patients and their families. This collaboration is a promising reflection of how partnerships between industry leaders and research organizations can spur the development of crucial therapies that enhance quality of life.

Understanding Rett Syndrome

Rett syndrome is a severe neurodevelopmental disorder primarily caused by random mutations affecting the MECP2 gene. While it predominantly impacts girls, occasional cases in boys are also observed. Symptoms typically manifest between 12 and 18 months of age, resulting in the loss of speech and motor skills, among other debilitating effects. Notably, despite the profound physical limitations caused by the disorder, many children retain their cognitive abilities.

Current Research and Future Directions

The Rett Syndrome Research Trust is dedicated to advancing research initiatives aimed at delivering innovative genetic therapies. They have initiated several clinical trials focused on genetic therapies that have the potential to knock down the barriers posed by Rett syndrome. Their significant recent venture includes a $40 million initiative aimed at bringing multiple genetic medicine candidates into clinical trials by a predetermined timeframe.
