LONDON--(BUSINESS WIRE)--AviadoBio, a pioneering gene therapy company dedicated to developing and delivering potentially transformative medicines for neurodegenerative disorders, today announced that the U.S. Food and Drug Administration (FDA) has cleared the Investigational New Drug (IND) application for AVB-101 to be studied in people with frontotemporal dementia (FTD) with mutations in the progranulin (GRN) gene. In addition, the FDA has granted Fast Track designation to AVB-101 for the treatment of FTD-GRN to slow disease progression. Fast Track is a process designed to facilitate the development and expedite the review of new drugs to treat serious conditions and fill an unmet medical need. Fast Track designation is intended to bring new medicines to patients earlier.
AVB-101 has been designed as a potential one-time therapy to halt disease progression by delivering a functional copy of the GRN gene to restore appropriate progranulin levels to areas of the brain affected by FTD. Both the U.S. FDA and the European Commission (EC) granted orphan designation to AVB-101 for the treatment of FTD in 2022. The company recently announced enrollment is open in European countries for ASPIRE-FTD, an open-label, multi-center dose-escalation study designed to evaluate the safety and preliminary efficacy of AVB-101 in patients with FTD-GRN.
“The IND clearance and Fast Track designation of AVB-101 are important milestones for the FTD community and for our company. Sadly, there are currently no disease-modifying therapies approved for the treatment of people living with frontotemporal dementia with progranulin mutations. Receiving Fast Track designation underscores the significant need for treatment options for these patients, and we are eager to soon open U.S. clinical trial sites and offer an innovative option for eligible patients with FTD-GRN,” said Lisa Deschamps, Chief Executive Officer.
“We are using adeno-associated virus (AAV) technology and taking a novel approach to deliver a functional copy of the GRN gene directly to the brain via bilateral, MRI-guided intrathalamic infusion with the aim to restore normal levels of the progranulin protein,” said David Cooper, M.D., Chief Medical Officer. “Our preclinical program shows robust biodistribution to the brain areas where it is needed to restore levels of progranulin, potentially slowing or stopping the progression of FTD-GRN, with little to no progranulin in the rest of the body where it may have adverse effects.”
FTD is a devastating form of early-onset dementia that typically leads to death within seven to 13 years of symptom onset and 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 FTD is a leading cause of dementia in people under the age of 654 with an estimated prevalence at any one time of up to 4.6 cases per 1,000 of people.5 Genetic FTD cases account for about one-third of cases and are most frequently associated with autosomal dominant mutations in three genes, including the progranulin gene.6
About ASPIRE-FTD
ASPIRE-FTD is an open-label, multi-center study designed to evaluate the safety and preliminary efficacy of AVB-101 in patients with FTD-GRN. In the study, AVB-101 will be delivered as a one-time treatment into the thalamus via a stereotactic neurosurgical procedure at expert neurosurgical centers throughout Europe and the United States.
More information about the ASPIRE-FTD study can be found at https://clinicaltrials.gov/study/NCT06064890.
About AVB-101
An experimental gene therapy, AVB-101, contains a correct (non-mutated) version of the GRN gene. It is designed to restore levels of progranulin in the brain, potentially slowing or stopping the progression of FTD-GRN. AVB-101 will be delivered as a ‘one-time dose’ directly into the brain via a minimally invasive surgical procedure, performed by a study neurosurgeon at a specialist neurosurgical center.
