Administered to the cerebrospinal fluid by infusion via a surgically implanted reservoir and catheter.

See prescribing information for complete administration details.
Approval was based on a nonrandomized, single-arm dose escalation study over 96 weeks. Results were compared with untreated patients from a natural history cohort. Twenty-four patients aged 3-8 years were enrolled in the clinical study. One patient withdrew after week 1 due to inability to continue with study procedures; 23 patients were treated with cerliponase alfa every other week for 48 weeks and continued treatment during the extension. Twenty-two patients were evaluated at week 96, and 21 (95%) did not have a decline in the motor domain of the CLN2 clinical rating scale. Only the patient who terminated early was deemed to have a decline in the motor domain of the CLN2 clinical rating scale.
