Purpose
Randomized, double-blind, parallel-group study to evaluate DiaPep0277 or placebo at baseline. Study medication will be administered
at time 0, 1 and 3 months, and then every 3 months for a total of 8 administrations. The total duration of the trial is 24
months (treatment for 18 months and follow-up for an additional 6 months). Patients will be male or female between the ages
of 30 and 55 years, inclusive, within 2 to 60 months of the diagnosis of diabetes mellitus. Subjects must be positive for
glutamic acid decarboxylate (GAD) autoantibodies. At the Screen Visit (Visit 2), all subjects will be asked to discontinue
their use of all oral antidiabetic medications with the exception of metformin. The subjects will be placed on a stable regimen
of insulin and diet (plus metformin if needed). Prior to the Baseline Visit (Visit 3), diabetic control must be achieved
by diet and insulin (plus metformin if needed).

Inclusion Criteria
Subjects meeting all of the following inclusion criteria at screening should be considered for admission to the study:
- The subject has a diagnosis of diabetes mellitus according to WHO classification for more than 2 months and less than 5 years
before enrollment.
- The subject's diabetes has been controlled by diet and insulin (plus metformin if needed) for 2 or more weeks (14 days) prior
to the Baseline Visit (Visit 3).
- The subject is a male or female aged 30 to 55 years. If female and not postmenopausal, the subject is not pregnant and will
use effective contraceptive methods throughout the study.
- The subject is positive for GAD autoantibodies, defined as a level greater than the 99th percentile of the GAD antibody index
of a normal control population for the laboratory (e.g., GAD antibody index equal to 0.085).
- The subject has a fasting C-peptide level 0.30 nmol/L or greater or 0.9 ng/mL at the time of the Screen Visit (Visit 2).
Exclusion Criteria
Subjects meeting any of the following exclusion criteria at screening will not be enrolled in the study:
- The subject has any significant diseases or conditions, including psychiatric disorders and substance abuse that, in the opinion
of the site investigator, are likely to affect the subject's response to treatment or their ability to complete the study.
- The subject has a history of any kind of malignant tumor.
- The subject has secondary diabetes mellitus.
- Within 2 weeks or 14 days of the Baseline Visit or during randomized treatment, the subject takes an oral anti-diabetic medication
other than metformin to treat his/her diabetes.
- The subject has clinical evidence of any diabetes-related complication that in the opinion of the site investigator would
interfere with the subject's participation in and/or completion of the study.
- The subject has a history of allergy or asthma that in the opinion of the site investigator would interfere with the subject's
participation in and completion of the study.
- The subject has a known immune deficiency from any disease, or a condition associated with an immune deficiency.
- The subject is receiving immunosuppressive or immunomodulating agents or cytotoxic therapy, or any medication that, in the
opinion of the site investigator, might interfere with the study.
- The subject is a pregnant woman or a woman who is planning to become pregnant.
- The subject has any of the following:
- chronic hepatitis or liver cirrhosis, or any other chronic liver disease
- is known to test positive for hepatitis B antigens or hepatitis C antibodies
- has abnormal liver function, defined as serum AST or ALT 3 times or more the upper limit of normal
- The subject is a known or suspected drug abuser.
- The subject has influenza-like symptoms on the day of dosing.
- The subject is known to test positive for HIV antibodies.
- The subject has chronic hematologic disease.
- The subject has impaired renal function (serum creatinine greater than 1.4 mg/dL).
- The subject has severe ketonuria (+++ on urine stix testing; ++ on repeated urine stix testing).
- The subject has a BMI greater than 40kg/m2.
- The subject fasting serum triglycerides greater than 1000 mg/dL). Suitable medical therapy for treatment of hyperlipidemia
is allowed.
- The subject has received any investigational drug within 3 months prior to Visit 1.
- The subject has had a severe blood loss (400 mL or more, e.g., blood donation) within 2 months before the first dosing of
the study medication.
