Diabetes Mellitus, Type 1 |
Drug: Polyclonal anti-T-cell antibodies |
Study Type: | Interventional |
Study Design: | Educational/Counseling/Training, Randomized, Single Blind, Placebo Control, Parallel Assignment, Safety/Efficacy Study |
Official Title: | The Use of Polyclonal Anti-T-Lymphocyte Globulin to Prevent Progression of Autoimmune Beta-Cell Destruction in Recent Type 1 Diabetes |
Estimated Enrollment: | 28 |
Study Start Date: | November 2000 |
Estimated Study Completion Date: | December 2007 |
This is a randomized, controlled, single-blind and parallel group study. After admission to the hospital, initial physical and laboratory examinations will be performed. Laboratory tests and medical treatment not related to the experimental protocol (except for immunosuppressive drugs) will be performed as clinically needed. Patients who fulfill the inclusion criteria and give their informed consent to participate in the study will be randomized to be treated either with a course of ATG-Fresenius together with intensified insulin therapy (Group 1) or with intensified insulin therapy only (Group 2).
For the study purpose, clinical and laboratory status of the patients will be assessed at 14 occasions (screening, visit 1 – visit 14). Thereafter, an extended follow-up study is planned with evaluations every 6 months.
Patients will be referred to the research institution by cooperating general practitioners and diabetes specialists, preferably before initiation of insulin therapy. After diabetes confirmation (according to WHO criteria) and initial clinical and biochemical examinations (typical for all patients with recent onset diabetes) the purpose, potential risk and benefits and the design of the study will be explained. Subjects willing to participate in the study will be asked to give their written informed consent.
All patients will be actively educated in diabetes management and intensified insulin therapy (3 – 4 daily injections of human insulin, glucose self-monitoring) will be initiated according to individual needs. In subjects randomized to Group 1, 4 doses of ATG Fresenius (first dose of 9 mg/kg of body weight, then 3 consecutive doses of 3 mg/kg) will be administered intravenously over 4 hours. Subjects in Group 2 will be treated with saline infusion (500 ml) on the same days. 1 hour before the first ATG administration, a cutaneous tolerance test (0.2 ml of the final solution) will be performed. Approximately 10 days after admission the patients will be dismissed. Besides scheduled ambulant visits, all subjects will be followed-up as clinically needed. In Paediatric patients (age 15-18 years), recommendations of a paediatric endocrinologist concerning diabetes management will be respected.
After completion of the study each patient’s diabetes specialist will be acquainted with the course of the treatment so far and the patients will be treated according to individual needs. They will be seen regularly once per year in the Department of Diabetes in IKEM for the next 3 years.
Discontinuation of the study:
Participation in the study may be at all times stopped according to the patient’s will. Should this require the medical status of the patients, the study may be interrupted based on the investigator’s decision during the period of ATG administration.
