Biomarin have released positive 48-week results from a clinical trial of cerliponase alfa treatment for CLN2 disease.

CLN2 disease is a form of Batten disease, a fatal neurodegenerative disease. It is the result of mutations in the TPP1/CLN2 gene causing deficient activity of the tripeptidyl peptidase 1 enzyme (TPP1). Cerliponase alfa treatment is a recombinant form of TPP1 and is designed to restore TPP1 enzyme activity.

In this Phase I/II trial, cerliponase alfa treatment was administered directly into the brain ventricles via intracerebroventricular infusions. At one year, the results have shown an 80 per cent reduction in the progression of the disease relating to decline in motor and language functioning, when compared to the natural progression of the disease. Furthermore, treatment was also found to reduce cortical grey matter loss.Biomarin plans to submit marketing applications and is planning to implement an early access programme to enable additional CLN2 patients to have access to this treatment.

The Great Ormond Street Hospital (GOSH) involvement in the trial was led by Novel Therapies Deputy Theme Lead, Professor Paul Gissen.
