Insights

Huntington

Area of Science:

  • Neuroscience
  • Biomarkers
  • Clinical Trials

Background:

  • Huntington's disease (HD) requires long-term therapy before motor diagnosis.
  • Early intervention necessitates sensitive biomarkers reflecting disease progression.
  • Current early-stage HD diagnosis relies on MRI-detected structural decline.

Purpose of the Study:

  • To systematically review and meta-analyze biofluid markers for Huntington's disease.
  • To identify validated biomarkers for pre-symptomatic, early-stage, and mid-stage HD.
  • To address limitations in current HD biomarker research and improve clinical trial methodology.

Main Methods:

  • Systematic literature search identifying 804 records.
  • Meta-analysis of 55 studies with reproducible findings.
  • Evaluation of biofluid markers including NfL, hydroxycholesterols, tau, cortisol, HDL, and mHTT.

Main Results:

  • Neurofilament light (NfL) is a validated prognostic biomarker for pre-symptomatic HD.
  • Four markers (24-OHC, 27-OHC, NfL, T-tau) are validated for early-stage HD.
  • Four markers (cortisol, HDL, mHTT, HTT) are validated for mid-stage HD.

Conclusions:

  • Eight biofluid markers are supported for validation across HD stages.
  • Improved reporting and rigor are needed to advance HD clinical trial methodology.
  • Validated biomarkers are crucial for effective Huntington's disease therapeutic strategies.
