The Safety and Efficacy of Administrating DiaPep277® Vaccination in Type 1 Diabetes Patients.

Type 1 diabetes is caused by an autoimmune process resulting in a selective destruction of the pancreatic insulin-secreting beta-cell. DiaPep277® is a small, lyophilized powder containing 24 Amino-acids. We have proved in former studies that DiaPep277® can slow down beta cells destruction in the pancreas and therefore decelerate the progress of Diabetes.

The objective of the study is to assess the efficacy and safety of administrating DiaPep277® in type 1 diabetes patients.

Inclusion Criteria:

2. Diagnosis of type 1 diabetes
3. No pregnancies or planned pregnancies of female subjects

Exclusion Criteria:

2. The subject has a history of any kind of malignant tumor (not including basal cell skin cancer).

3. The subject has clinical evidence of any diabetes-related complication that in the opinion of the Investigator would interfere with the subject's participation in and/or completion of the study.

4. Subject has history of endogenous allergic reactivity:

   • Severe allergic reaction or severe exacerbation of allergic asthma within 12 months prior to the Screening-Ext Visit.
   • Ongoing systemic asthma treatment.
   • Subjects with history of life threatening or severe allergy, re-occurrence of which cannot be ruled out based on the Investigator's judgment.

5. The subject has known allergy to lipid emulsions.

6. The subject has a known immune deficiency from any disease, or a condition associated with an immune deficiency.

7. The subject is receiving immunosuppressive or immunomodulating agents or cytotoxic therapy or any medication that in the opinion of the Investigator might interfere with the study.

8. The subject has any of the following clinically significant laboratory abnormalities:

   • Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) greater than three times the upper limit of the normal (ULN) at the Screening-Ext Visit.
   • Total bilirubin greater than 1.3 times the ULN at the Screening-Ext Visit.
   • Subjects with severe renal failure at the Screening-Ext visit (as defined by glomerular filtration rate < 30 mL/min/1.73 m2 by Cockroft und Gault calculation • Clinically significant laboratory abnormalities, confirmed by repeat measurement, which may interfere with the assessment of safety and / or efficacy of the study drug, other than hyperglycemia and glycosuria at the Screening-Ext Visit.
   • Fasting triglycerides <1000 mg/dL (11.3 mmol/L) at the Screening-Ext Visit. Suitable medical therapy for treatment of hyperlipidemia is allowed.
