• Cerliponase alfa (Brineura) is indicated to slow the loss of ambulation in symptomatic pediatric patients 3 years of age and older with late infantile neuronal ceroid lipofuscinosis type 2 (CLN2), also known as tripeptidyl peptidase 1 (TPP1) deficiency.
• The information was derived from a Randomized Controlled Trial.
• In terms of effectiveness, Brineura showed significant results in slowing CLN2 disease progression compared to historical controls. The median time until a two-point decline in motor-language score was not reached for those treated with Brineura, versus 345 days for the control group.
• Safety concerns associated with this drug include convulsions, fever, vomiting, hypersensitivity reactions, and failure of the intraventricular device used for infusions. Serious adverse events included device-related infections requiring antibiotic treatment and device replacement.
• The study focused on symptomatic pediatric patients aged between three to sixteen years old suffering from CLN2 disease but did not provide detailed subgroup information such as variability in response related to age or severity of disease.
• While Brineura offers promising therapeutic benefits for children suffering from CLN2 disease by significantly slowing its progression compared to no treatment, attention must be given towards maintaining the infusion devices properly and monitoring possible adverse reactions due to its administration risks.
