Active Ingredient: Eladocagene exuparvovec

Indication for Eladocagene exuparvovec

Population group: only children (1 year - 12 years old) , adolescents (12 years - 18 years old) , adults (18 years old or older)
Therapeutic intent: Curative procedure

Eladocagene exuparvovec is indicated for the treatment of patients aged 18 months and older with a clinical, molecular, and genetically confirmed diagnosis of aromatic L-amino acid decarboxylase (AADC) deficiency with a severe phenotype.

Total dose of 1.8 × 10¹¹ vg as four 0.08 mL infusions

For:

Dosage regimens

Intracerebral, 0.08 milliliters eladocagene exuparvovec, 4 doses in total.

Detailed description

Patients will receive a total dose of 1.8 × 1011 vg delivered as four 0.08 mL (0.45 × 1011 vg) infusions (two per putamen).

The posology is the same for the entire population covered by the indication.

Dosage considerations

Intraputaminal use.

Four separate infusions of equal volumes are performed to the right anterior putamen, right posterior putamen, left anterior putamen, and left posterior putamen.

The target infusion sites are defined per standard stereotactic neurosurgical practice. Eladocagene exuparvovec is administered as a bilateral infusion (2 infusions per putamen) with an intracranial cannula. The final 4 targets for each trajectory should be defined as 2 mm dorsal to (above) the anterior and posterior target points in the mid-horizonal plane.

Active ingredient

Eladocagene exuparvovec

Eladocagene exuparvovec is a gene therapy based on recombinant AAV2 vector containing the human cDNA for the DDC gene. After infusion into the putamen, the product results in the expression of the AADC enzyme and subsequent production of dopamine, and consequently, development of motor function in treated AADC-deficient patients.
