LONDON July 1, 2024AviadoBio, a pioneering gene therapy company dedicated to developing and delivering potentially transformative medicines for neurodegenerative disorders, today announced that its Phase 1/2 ASPIRE-FTD clinical trial is now open and recruiting patients in the United States at The Ohio State University. ASPIRE-FTD is evaluating AviadoBio’s investigational gene therapy, AVB-101, in people with frontotemporal dementia (FTD) with progranulin (GRN) gene mutations (FTD-GRN). The study is also recruiting in Europe with study sites in the Netherlands, Poland, and Spain, with additional sites expected to open in multiple countries.

FTD is a devastating form of early-onset dementia that typically leads to death within three to 10 years from diagnosis.¹,² People with FTD commonly experience personality changes, behavioral disturbance, loss of language, apathy, and reduced mobility.³ It is a leading cause of dementia in people under the age of 65 and is often misdiagnosed.⁴ People with FTD who have disease-causing GRN mutations produce a reduced amount of progranulin protein. AVB-101 is a potential one-time therapy designed to stop disease progression by delivering a functional copy of the GRN gene to restore appropriate progranulin levels to affected areas of the brain.

“People living with FTD-GRN have no available disease-modifying treatments and the impact of this disorder is profound for both patients and their families,” said neurosurgeon Dr. James “Brad” Elder, professor of neurological surgery at The Ohio State University Wexner Medical Center. “There is an urgent need for collaboration between researchers, clinicians, patients, advocates, and families to courageously explore new approaches for FTD, including innovative and targeted delivery approaches. This study will allow us to investigate how highly targeted GRN supplementation could be a potential breakthrough treatment.”

“Although delivery of progranulin protein via gene therapy is known to be possible, effective brain delivery remains a challenge primarily due to the anatomy of the brain,” said David Cooper, M.D., Chief Medical Officer of AviadoBio. “Our goal is to use intrathalamic delivery to facilitate the biodistribution of PGRN protein to areas of the cortex affected by FTD. The therapy has already shown great promise in preclinical studies, and we now look forward to taking this important next step in its clinical development.”

AVB-101 is delivered as a one-time-only treatment using a minimally invasive, stereotactic neurosurgical procedure directly to the part of the brain called the thalamus. The thalamus has extensive connections throughout the brain, including the frontal and temporal lobes, which play a critical role in FTD. This targeted delivery method aims to safely and effectively cross the blood-brain barrier, delivering the investigational gene therapy directly to the brain to restore GRN levels in the frontal and temporal cortex where it is needed most, while at the same time reducing the dose required and the potential systemic exposure.

“Thousands of people are diagnosed with FTD each year. The relatively early onset of FTD and often strongly hereditary nature can make it all the more challenging for patients and their families,” said Lisa Deschamps, AviadoBio’s Chief Executive Officer. “We are grateful to the patients and families with FTD-GRN involved in ASPIRE-FTD, as well as The Ohio State University researchers for their dedication to investigating AVB-101’s great potential in stopping disease progression and offering hope to patients and their loved ones.”
