Investigating the role of the innate immune system in ALS

Amyotrophic Lateral Sclerosis and the Innate Immune System

Rigshospitalet, Denmark · NCT02869048

This study is trying to see how the body's immune system affects the progression of ALS by collecting samples from ALS patients and healthy individuals.

What this trial studies

This observational study focuses on understanding the role of the innate immune system, particularly the complement system, in the progression of Amyotrophic Lateral Sclerosis (ALS). It aims to gather biological specimens from patients diagnosed with ALS and control groups to analyze the activation of complement proteins. By examining these immune responses, the study seeks to uncover potential mechanisms behind ALS and inform future treatment strategies. The research is conducted across multiple hospitals in Denmark, involving both ALS patients and neurological controls.

Who should consider this trial

Good fit: Ideal candidates include individuals diagnosed with 'certain ALS' or 'likely ALS' according to established diagnostic criteria.

Not a fit: Patients with chronic inflammatory diseases, autoimmune diseases, or those who are neurologically healthy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to a better understanding of ALS and pave the way for new therapeutic approaches.

How similar studies have performed: Previous studies have suggested a link between the complement system and ALS, indicating that this approach may yield valuable insights.
