Multi-center, Randomized, Double-blind, Placebo-controlled Trial to Evaluate the Effects of Intra-Erythrocyte Dexamethasone Sodium Phosphate on Neurological Symptoms in Patients With Ataxia Telangiectasia
Abstract
Objectives:
The objective of study was to evaluate the safety and the efficacy of EryDex (Dexamethasone sodium phosphate encapsulated in autologous erythrocytes, using the EryDex System - EDS) at two dose levels (low dose and high dose DSP/infusion), compared to placebo, on Neurological Symptoms in Patients With Ataxia Telangiectasia.
Initial Double-Blind Treatment Period (0 to 6 Months)
Primary Efficacy Objective:
• Evaluate the effect of EryDex at two dose levels (low dose and high dose DSP/infusion), compared to placebo, on central nervous system (CNS) symptoms measured by the change in the Modified International Cooperative Ataxia Rating Scale (mICARS) from baseline to Month 6 (Visit 9) in patients with ataxia telangiectasia (A-T).
Secondary Efficacy Objectives:
* Evaluate the effect of EryDex, compared to placebo, on the Clinical Global Impression of Change (CGI-C) in patients with A-T from baseline to Month 6 (Visit 9).
* Evaluate the effect of EryDex, compared to placebo, on measures of Clinical Global Impression of Severity (CGI-S; structured) in patients with A-T from baseline to Month 6 (Visit 9)
* Evaluate the effect of EryDex, compared to placebo, on measures of Adaptive behavior measures in patients with A-T by the Vineland Adaptive Behavior Scales (VABS) from baseline to Month 6 (Visit 9).
Safety Objectives:
• Evaluate the safety and tolerability of two non-overlapping doses of EryDex, compared to placebo, in patients with A-T over the 12-month double-blind…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 176 participants or records.
