Summary

This is a biomarker study designed to collect and analyze blood specimens from individuals carrying known familial frontotemporal lobar degeneration (f-FTLD) mutations compared to a control group of individuals without known f-FTLD mutations. The NSP is an ancillary study to the ARTFL LEFFTDS Longitudinal Frontotemporal Lobar Degeneration" (ALLFTD) study, NCT04363684. More information can be found at https://www.allftd.org/.

Description

Frontotemporal Lobar Degeneration (FTLD), a group of clinically heterogeneous neurodegenerative diseases characterized by progressive deterioration of the frontal and temporal cortices as well as basal ganglia and brainstem structures, is a common cause of neurodegenerative dementia in people who are less than 60 years old at onset. It is uniformly fatal. FTLD is a rare disease, with an estimated prevalence of approximately 5-22 per 100,000. There are no approved treatments, however several investigational agents are in human trials and a variety of novel agents are poised to enter human development. Experience from other neurodegenerative diseases suggests that potential disease modifying treatments are most likely to be efficacious if initiated before the onset of symptoms.

Approximately 25% of FTLD cases are familial (f-FTLD) and due to autosomal dominant mutations in one of three genes: C9orf72, progranulin (GRN) or microtubule associated protein tau (MAPT). Many of the new therapies entering the clinic directly target one of these genetic causes and raise the possibility that the clinical features of FTLD could be delayed or prevented in these individuals if an efficacious therapy was initiated prior to the onset of symptoms. The major barrier to determining efficacy of novel therapeutic agents for f-FTLD in such prevention trials is the lack of an endpoint that can indicate therapeutic efficacy prior to the onset of symptoms. Our preliminary data strongly suggest that plasma neurofilament light chain (NfL) could serve as such a biomarker.

This non-interventional study is in preparation for pivotal clinical trials. Up to 335 participants will provide blood remotely via visits from traveling mobile research nurses four times a year for three years (4355 samples total) to enable the observation of peripheral NfL levels longitudinally during disease onset and progression, with the ultimate goal of qualifying plasma NfL as an endpoint for f-FTLD prevention trials. The NSP study is an ancillary study to ALLFTD, and biomarker data collected in the NSP will be correlated with ALLFTD clinical data.
