Frequently asked questions about AAV9-hSyn1-miGRIK2

What is AAV9-hSyn1-miGRIK2 used for?

AAV9-hSyn1-miGRIK2 is an investigational gene therapy being developed for the treatment of mesial temporal lobe epilepsy, a form of epilepsy that originates in the medial part of the temporal lobe. It is currently in Phase 1 clinical development and has not been approved by regulatory authorities.

What does AAV9-hSyn1-miGRIK2 target?

AAV9-hSyn1-miGRIK2 targets the GRIK2 gene, which encodes a subunit of kainate-type glutamate receptors. By delivering a microRNA designed to reduce GRIK2 expression, the therapy aims to modulate neuronal excitability in the brain, potentially reducing seizure activity in patients with mesial temporal lobe epilepsy.

Who is developing AAV9-hSyn1-miGRIK2?

AAV9-hSyn1-miGRIK2 is being developed by uniQure N.V., a biotechnology company publicly traded under the ticker symbol QURE. The company is conducting clinical trials to evaluate the safety and efficacy of this gene therapy for mesial temporal lobe epilepsy.

What phase is AAV9-hSyn1-miGRIK2 in?

AAV9-hSyn1-miGRIK2 is in Phase 1 clinical development. It is an investigational therapy, meaning it has not yet received regulatory approval and is being studied in a clinical trial to assess its safety and potential efficacy in patients with mesial temporal lobe epilepsy.

What clinical trials is AAV9-hSyn1-miGRIK2 in?

AAV9-hSyn1-miGRIK2 is being evaluated in a Phase 1 clinical trial with the identifier NCT06063850. This study, titled 'AMT-260 Gene Therapy Study in Adults With Unilateral Refractory Mesial Temporal Lobe Epilepsy,' is currently recruiting participants in the United States and aims to enroll 12 adults aged 18 years and older.

Is AAV9-hSyn1-miGRIK2 the same as AMT-260?

Yes, AAV9-hSyn1-miGRIK2 is also known as AMT-260. The clinical trial NCT06063850, which is investigating this gene therapy for mesial temporal lobe epilepsy, uses the name AMT-260 in its title, confirming that both names refer to the same investigational drug.
