KEBILIDI (eladocagene exuparvovec-tneq) · PTC Therapeutics

Biodistribution (within the body) and Vector Shedding (excretion/secretion) KEBILIDI vector DNA levels in various tissues and secretions were determined using a validated quantitative polymerase chain reaction (qPCR) assay. Nonclinical data Biodistribution of eladocagene exuparvovec-tneq was evaluated in rats at Days 7, 30, 90, and 180 after single-dose intraputaminal infusion at dose levels up to 7.5×10 9 vg/animal (21-fold higher than the recommended human dose based on relative brain weight)....

The efficacy of KEBILIDI was evaluated in one open-label, single arm study (Study 1; NCT04903288). The study enrolled pediatric patients with genetically confirmed, severe AADC deficiency who had achieved skull maturity assessed with neuroimaging. The main efficacy outcome measure was gross motor milestone achievement evaluated at week 48 and assessed using the Peabody Developmental Motor Scale, Second Edition (PDMS-2). Patients treated with KEBILIDI were compared to an external untreated natural history cohort of 43 pediatric patients with severe AADC deficiency who had at least one motor mil...

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

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 )

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 respir...
