Eladocagene Exuparvovec-tneq

1 INDICATIONS AND USAGE 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 [see Clinical Studies ( 14 )] . 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.

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

8.1 Pregnancy Risk Summary There are no clinical data from the use of KEBILIDI in pregnant women. Animal reproductive and developmental toxicity studies have not been conducted with KEBILIDI. In the US general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

5 WARNINGS AND PRECAUTIONS Procedural complications: Monitor patients for procedural complications for neurosurgery, including events of respiratory and cardiac arrest after administration of KEBILIDI. ( 5.1 ) Dyskinesia: Monitor patients for dyskinesia after treatment with KEBILIDI. The use of dopamine antagonists can be used to control dyskinesia symptoms. ( 5.2 ) 5.1 Procedural Complications Procedural complications have been reported after neurosurgery required for KEBILIDI administration. These events included respiratory and cardiac arrest which occurred within 24 hours of the neurosurgical procedure and during post-surgical care [see Adverse Reactions (6) ] . 4 CONTRAINDICATIONS 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. ( 4 )
