Eladocagene exuparvovec

KEBILIDI (eladocagene exuparvovec-tneq) is an adeno-associated virus (AAV) vector-based gene therapy indicated for the treatment of adult and pediatric patients with aromatic L-amino acid decarboxylase (AADC) deficiency. This indication is approved under accelerated approval based on the change from baseline in gross motor milestone achievement at 48 weeks post treatment. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory clinical trial. KEBILIDI is an adeno-associated virus (AAV) vector-based gene therapy indicated for the treatment of adult and pediatric patients with aromatic L amino acid decarboxylase (AADC) deficiency. This indication is approved under accelerated approval based on change from baseline in gross motor milestone achievement at 48 weeks post-treatment.

KEBILIDI is a recombinant adeno-associated virus serotype 2 (rAAV2) based gene therapy designed to deliver a copy of the DDC gene which encodes the AADC enzyme. Intraputaminal infusion of KEBILIDI results in AADC enzyme expression and subsequent production of dopamine in the putamen.

For single-dose intraputaminal infusion only. Recommended dose: 1.8×10 11 vector genomes (vg). Brain imaging for stereotactic planning and intraoperative navigation should be done prior to the procedure. Post stereotactic registration, mark the entry point on the skull. Surgical access through the skull bone and dura should be performed. Administer a total dose of 1.8×10 11 vg (0.32 mL total volume) delivered as four 0.08 mL (0.45×10 11 vg) infusions (two sites per putamen-anterior and posterior) at a rate of 0.003 mL/minute (0.18 mL/hour) for a total of 27 minutes per site, administered in a single stereotactic surgery using a cannula that is FDA-authorized for intraparenchymal infusion.

KEBILIDI is contraindicated in patients who have not achieved skull maturity assessed by neuroimaging. Skull maturity is needed for stereotactic neurosurgical administration of KEBILIDI. Patients who have not achieved skull maturity assessed by neuroimaging.

Procedural complications: Monitor patients for procedural complications for neurosurgery, including events of respiratory and cardiac arrest after administration of KEBILIDI. Dyskinesia: Monitor patients for dyskinesia after treatment with KEBILIDI. The use of dopamine antagonists can be used to control dyskinesia symptoms.

Most common adverse reactions (incidence ≥15%) were dyskinesia, pyrexia, hypotension, anemia, salivary hypersecretion, hypokalemia, hypophosphatemia, insomnia, hypomagnesemia, and procedural complications.

Store and transport frozen at ≤-65°C (-85°F). If not used immediately, store at room temperature (up to 25°C [77°F]) and use within 6 hours of starting product thaw.
