propidium and Devic Disease

propidium has been researched along with Devic Disease in 1 studies

Propidium: Quaternary ammonium analog of ethidium; an intercalating dye with a specific affinity to certain forms of DNA and, used as diiodide, to separate them in density gradients; also forms fluorescent complexes with cholinesterase which it inhibits.

Trial Outcomes

Change in Expanded Disability Status Scale (EDDS) Score

The EDSS is an ordinal clinical rating scale ranging from 0 (normal neurologic examination) to 10 (death) in half-point increments. (NCT00904826)
Timeframe: baseline, 12 months

Interventionunits on a scale (Mean)
Eculizumab-0.7

Mean Eculizumab Concentration in Cerebrospinal Fluid (CSF)

(NCT00904826)
Timeframe: 3 months

Interventionng/mL (Mean)
Eculizumab34.7

Number of Subjects With Change in Ambulation by at Least 1 Point

Ambulation was measured by the Hauser Ambulation Index, which ranges from 0 (asymptomatic; fully active) to 9 (restricted to wheelchair; unable to transfer self independently.) (NCT00904826)
Timeframe: 12 months

Interventionparticipants (Number)
Eculizumab3

Number of Subjects With Change in Visual Acuity in at Least One Eye by at Least One Point

Visual acuity was measured using the the Visual Acuity subscale of the Opticospinal Impairment Score (OSIS) for Exacerbations. This subscale ranges from 0 (normal) to 8 (no light perception). (NCT00904826)
Timeframe: 12 months

Interventionparticipants (Number)
Eculizumab5

Percentage Hemolysis

Percentage of hemolysis is a measure of complement activity. Less than 20% lysis is deemed to be complete complement inhibition. (NCT00904826)
Timeframe: baseline, 6 weeks, 3 months, 6 months, 9 months, 12 months
