Official answer


Brineura (cerliponase alfa) is used to slow the loss of ambulation (ability to crawl or walk unaided) in patients with late infantile neuronal ceroid lipofuscinosis type 2 (CLN2), also known as tripeptidyl peptidase 1 (TPP1) deficiency. Brineura is used in pediatric patients 3 years of age and over who have symptomatic disease.

CLN2 is a neurodegenerative disease and a type of Batten disease. It is caused by a lack of the enzyme TPP1, which leads to the build up of lysosomal storage materials in the central nervous system (CNS) and results in a progressive decline in motor function.

Brineura is a proenzyme of TPP1. It is taken up by the CNS and is activated in the lysosomes, which results in their break down.
