Longitudinal Biofluids Core

Research

In 2021, Target ALS launched a natural history study to generate the most comprehensive collection of longitudinal biofluid samples and data from at least 800 ALS and 200 healthy control cases. The multi-center study is conducted by the Target ALS Biofluid Consortium, recently expanded to comprise 14 ALS clinics located around the globe, and growing. The study includes collection of detailed clinical and demographic information, speech and respiratory functional data, multiomic datasets, and longitudinal biofluid collection of CSF, blood, and urine. De-identified data and samples are available to academic and industry organizations to accelerate discovery of novel therapeutics and biomarkers.

Outreach and Diversity

We are deeply committed to finding a cure for all patients. Lack of research in diverse populations and underrepresented communities impedes progress in understanding the cause of ALS.  Target ALS sponsors several programs to fill this gap. First, we are expanding our biofluid consortium to include 10 international clinics with access to diverse patient populations. Second, in collaboration with the Chan Zuckerberg Initiative and Barrow Neurological Institute, we are creating outreach programs for patients in rural communities to participate in research through a simple at-home questionnaire and blood sample kit. Third, we are providing travel reimbursement to allow patients to easily access ALS clinics to participate in the Natural History Study.

Access to Target ALS Core Resources

As with all the core resources created by Target ALS, samples and data will be accessible to researchers worldwide, with no-strings-attached. The goal of this core is to provide access via a conflict-free and expeditious sample request process. De-identified biofluid samples are currently available for request from 113 participants – 51 healthy controls and 62 participants with ALS.  Subject data including clinical, demographic, digital measures of function, and WGS is currently available in the Target ALS Data Portal. Additional multi-omic datasets and neurofilament light levels will become available by end of 2024..  Subject data including clinical, demographic, multi-omic datasets, and neurofilament light levels will become available via the Target ALS Data Portal. These data can be mined along with data from our Postmortem Tissue Collection.

A link to the sample request form is here. Sample requests will be approved by an Independent Review Committee on a once-monthly basis, followed by a short virtual meeting to discuss the sample needs and research plan with each investigator. A Materials Transfer Agreement (MTA) will be executed upon approval of the request.

Confidentiality of investigator’s data, research, and intellectual property will be strictly honored.
Target ALS does not seek ownership of any intellectual property or financial gains that result on the
basis of its funding or in-kind contributions.
