Natalizumab for the Treatment of People With Inflammatory Demyelination Suggestive of Multiple Sclerosis, or Definite Multiple Sclerosis, at First Presentation (AttackMS)
Recruiting now · Phase 2 · Has a placebo group
Conditions studied: Multiple Sclerosis, Clinically Isolated Syndrome of Demyelination
In brief
Multiple Sclerosis (MS) is a chronic inflammatory \& degenerative disease of the central nervous system (CNS) Recent data from the MS Base registry demonstrated an average delay of 152 - 215 days between first presentation and the diagnosis of MS, and more than one year until Disease Modifying Treatment (DMT) begins. Evidence suggests that shutting down inflammation using highly effective DMTs early after diagnosis leads to better long term clinical outcomes The AttackMS trial will test the effect of starting a highly-effective DMT licensed for MS, Tyruko® (Natalizumab 300mg), within a short time - 14 days - after symptom onset.
