Multi-centre, single arm, open label, 6 months, phase II study to evaluate the effect of Ery-Dex in improving Central Nervous System (CNS) symptoms in patients with Ataxia Teleangiectasia (AT). The study consists of a screening period (max duration of 30 days) and a treatment period (duration 6 months).

Further study details as provided by Erydel:

Primary Outcome Measures:
  • Changes in Neurological symptoms assessed by using ICARS score [ Time Frame: At the end of 6 months of treatment ] [ Designated as safety issue: No ]
    ICARS is a 100-point semiquantitative scale offering a compartimentalised quantification of 4 subscores: Posture and Gait disorders; Kinetic functions; Speech Disorders and Oculomotor Disorders, for a possible total of 100 (highest score corresponds to the worst status of the patient).

Secondary Outcome Measures:
  • Assessment of safety [ Time Frame: During the whole treatment period ] [ Designated as safety issue: Yes ]
    Evaluate the effect of Ery-Dex on treatment emergent adverse events including Serious Adverse Events (SAEs) and laboratory parameters

  • Vineland adaptive behaviour scale (VABS) [ Time Frame: At the end of the study ] [ Designated as safety issue: No ]
    To evaluate the effect of Ery-Dexon adaptive behavior measured by VABS

Primary Completion Date: September 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Ery-Dex
Patients treated with monthly treatment of Ery-Dex (dexamethasone sodium phosphate encapsulated in autologous erythrocytes)
Drug: Dexamethasone
dexamethasone encapsulated in human erythrocytes. One infusion per month of about 10-15 mg of dexamethasone. The treatment covers 1 month of therapy-
Other Names:
  • Dexamethasone sodium phosphate
  • Dex 21P

Detailed Description:
The study has the aim to evaluate the improvement in CNS symptoms measured by International Co-operative Ataxia Rating Scale (ICARS) in patients with AT, during a period of treatment with Ery-Dex (dexamethasone sodium phosphate ex vivo encapsulated into human autologous erythrocytes).
