This is a multicenter, observational study for patients with a confirmed diagnosis of neuronal ceroid lipofuscinosis type 2 (CLN2 disease), also known as TPP1 deficiency, who intend to be or are currently being treated with cerliponase alfa. Patients receiving or expected to receive cerliponase alfa within 60 days of signing the informed consent form (ICF) may be eligible to enroll in the study, assuming all regulatory requirements for sites that have agreed to participate and protocol inclusion criteria are met. Data may be collected for all or some of the assessments as outlined in the protocol, dependent upon the clinic's and/or individual patient's standard of care.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
BioMarin Pharmaceutical (BMRN) is the sponsoring company for this trial. BiotechSign currently grades this company D (49/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
