Open Actively Recruiting

Open-label, Long-term, Extension Treatment Using Intra-Erythrocyte Dexamethasone Sodium Phosphate in Patients With Ataxia Telangiectasia Who Participated in the IEDAT-02-2015 Study

About

Brief Summary

This is an international (North America, Europe, Africa, Asia and Australia), multi-center, prospective, open-label treatment study, designed to continue to provide the study medication to all patients who completed 12 months of treatment (including those treated with placebo) in the IEDAT-02-2015 trial, completed the study assessments, do not present safety contraindication to continuation of treatment, and provided informed consent. The study aims to collect information on the long-term safety and efficacy of the trial treatment.

Inclusion Criteria:

  • Patient completed the double-blind period in the IEDAT-02-2015 trial and must have completed the final (Visit 15/Month 12) efficacy assessments of IEDAT-02-2015.
  • Patient tolerated the study medication, without any evidence of steroid adverse events, or treatment-related severe/ serious adverse events
  • Body weight > 15 kg.
  • The patient and his/her parent/caregiver (if below the age of consent), or a legal representative, has provided written informed consent to participate. If consent is provided solely by the caregiver in accordance with local regulations, the patient must provide assent to participate in the study
  • Patient does not present safety contraindication for continuation of treatment, as determined by the Principal Investigator (PI) according to the procedures described below. Procedure for selecting patients for further treatment in IEDAT-03-2018: The Principal Investigator will ask all patients who meet the above requirements, and determine their interest in continuing to receive treatment with the study medication in a new protocol. The Principal Investigator will then determine the eligibility of the patients on the basis of his/her clinical judgement of patients' status and their safety.

Exclusion Criteria:

General

  • Females that are
    • pregnant, or are breast-feeding (for EU countries only);
    • of childbearing potential, pregnant, or are breast-feeding (for US and Rest of World countries). Females of childbearing potential using adequate birth control, as determined by their Health Care Provider, will be eligible.
  • A disability that may prevent the patient from completing all study requirements.
  • Current participation in a clinical study with another investigational drug. Medical History and Current Status
  • CD4+ lymphocytes count <400/mm3 (for patients 6 years of age) or <200/mm3 (for patients >6 years).
  • Current neoplastic disease.
  • Severe impairment of the immunological system.
  • Severe or unstable pulmonary disease.
  • Uncontrolled diabetes. Patients with diabetes that has been stabilized (i.e. no hypoglycemic or hyperglycemic episodes in the past 3 months) will be eligible.
  • Any other severe, unstable, or serious disease or condition that in the Investigator's opinion would put the patient at risk for imminent lifethreatening morbidity, need for hospitalization, or mortality.
  • Eligibility of patients with abnormal laboratory test values will be determined by the Investigator.
  • Confirmed hemoglobinopathies, e.g. hemoglobin C disease, sickle cell anemia, or thalassemia.
  • Moderate or severe renal and/or hepatic impairment.
  • Patients who experienced moderate/ severe steroid side effects, or moderate/ severe adverse events associated with the study medication administered in the IEDAT-02 study. Prior/Concomitant Medication
  • Requires treatment with an oral or parenteral steroid. Treatment with inhaled or intranasal steroids for asthma or allergies, as well as use of topical steroids will be permitted.
  • Requires any other concomitant medication prohibited by the protocol.
