Conditions

Fronto-Temporal Dementia with Progranulin Mutations (FTD-GRN)

Brief summary

The following primary safety endpoints will be measured up to 5 years: • Incidence and severity of treatment-emergent adverse events and serious adverse events (see study protocol for details)., • For patients who received Sirolimus: treatment-emergent hypercholesterolemia or hyperlipidemia; treatment-emergent proteinuria; treatment-emergent interstitial lung disease; and sirolimus trough levels., • For patients who received Rituximab: treatment-emergent hypogammaglobulinemia; and lymphocyte immunophenotyping., • Incidence of procedure or treatment-emergent safety findings per brain and spine MRI., • Change from baseline in immunogenicity of AAV9, PGRN, and NfL in blood and in CSF over time., The following are the primary efficacy endpoints: • Change from baseline in PGRN levels in blood over time. • Change from baseline in PGRN levels in CSF over time.

Detailed description

• Change from baseline in CDR plus NACC FTLD over time. • Change from baseline in NfL levels in blood over time. • Change from baseline in NfL levels in CSF over time.
