Study Title

CReATe Consortium: PGB2 (Phenotype-Genotype-Biomarkers) Study

Enrollment Status

Recruiting

Principal Investigators

Michael Benatar, MD, PhD

Study Type

Observational

Goals

  • Better understand the phenotype-genotype relationship in ALS and related disorders, as well as the potential impact of environment exposures
  • Develop biomarkers that might be useful in aiding therapy development for this group of disorders
  • Validate the first ALS-specific patient reported outcome measure for use in future clinical trials
  • Evaluate the utility of blood-based measurements of neurofilaments for the diagnosis of ALS

Enrolling

ALS, PMA, PLS, HSP, or MSP patients

Eligibility

Primary participants:

  • Clinical diagnosis (or suspicion) of ALS or a related disorder, including progressive muscular atrophy (PMA), primary lateral sclerosis (PLS), hereditary spastic paraplegia (HSP), and multi-system proteinopathy (MSP)
  • Able and willing to comply with study procedures

Secondary participants:

  • Family members (both affected and unaffected) of primary participants

Study visits entail:

  • Family and medical history review
  • Blood, urine, and (optional) CSF collection
  • Neurological exam
  • Neuropsychological assessment
  • Breathing test
