Criteria

Inclusion Criteria:

All of the following criteria are to be fulfilled for inclusion of an individual in the study. An eligible individual:

1. Is male or female and is 18 to 50 years of age

2. Has been diagnosed with T1DM for at least 1 year. Diagnosis of T1DM will be based on clinical criteria including: insulin-dependence within 6 months of the onset, history of prior episode of ketoacidosis, previous documentation of positive serum islet cell autoantibodies or low or undetectable serum C-peptide levels.

3. Has an HbA1c 7.0 to 10.0 %, inclusive

4. Currently on insulin pump or on a combination of basal (long-acting insulin preparation) and pre-prandial (short-acting insulin preparation) insulin therapy

5. Is male, or if female of childbearing potential, is non-lactating, and has a negative pregnancy test (human chorionic gonadotropin, beta subunit [βhCG]) result at screening (Visit 1) and Visit 2 regardless of menopausal status (If female and of childbearing potential [including peri menopausal women who have had a menstrual period within one year], must practice and be willing to continue to practice appropriate birth control [defined as a method which results in a low failure rate, i.e., less than 1% per year, when used consistently and correctly, such as implants, injectables, oral contraceptives, some intrauterine contraceptive devices, sexual abstinence, tubal ligation, or a vasectomized partner] during the entire duration of the study.)

6. Has a BMI < 27 kg/m2

7. Has clinical laboratory test values (clinical chemistry, hematology, and urinalysis) judged to be not clinically significant by the investigator at screening (Visit 1)

8. Has a physical examination and electrocardiogram (ECG) with no clinically significant abnormalities as judged by the investigator

Exclusion Criteria:

1. Has a fasting serum triglyceride concentration >400 mg/dL at screening

2. Has hypoglycemia unawareness (Loss of consciousness due to hypoglycemia without preceding symptoms or recent history of blood glucose <50 mg/dl without symptoms)

3. Currently abuses drugs or alcohol, or has a history of abuse that in the investigator's opinion could cause the individual to be noncompliant with study procedures, or has a positive urine screen for drugs of abuse at screening (Visit 1)

4. Has chronic renal insufficiency with serum creatinine > 2 mg/dL

5. Has a history of weight loss (>3%) in the last 3 months

6. Is currently enrolled or plans to enroll in a diet, weight loss, or exercise program

7. Has a sitting blood pressure >160/95 mmHg (either systolic or diastolic) at screening (Visit 1)

8. Has a clinically significant history or presence of any of the following conditions:

• Active cardio- or cerebrovascular disease

• Active pulmonary disease

• Hepatic disease defined as follows:

• At screening (Visit 1), alanine transaminase (ALT), aspartate transaminase (AST), or alkaline phosphatase > three times the upper limit of normal (elevated Liver Function Test values suggestive of obesity related non-alcoholic fatty liver disease may not be exclusionary)

• The presence of any other co morbid disorders that, in the opinion of the investigator, would interfere with the subject's compliance of study procedures

• Clinically significant malignancies within 5 years of screening (Visit 1)

• Chronic infections (e.g., HIV [human immunodeficiency virus] or tuberculosis)

9. Has received any investigational drug within 30 days or within a period corresponding to five half-lives of that drug, whichever is greater, before screening (Visit 1)

10. Has had major surgery or a blood transfusion within 2 months before screening (Visit 1) or has a hematocrit < 30%

11. Has a known hypersensitivity to any of the components of the study treatment (e.g. has a known hypersensitivity to E. Coli derived proteins

12. Is an immediate family member (spouse, parent, child, or sibling; biological or legally adopted) of personnel directly affiliated with the study at the investigative site, or is personally directly affiliated with the study at the investigative site

13. Is employed by Amylin Pharmaceuticals, Inc., (i.e., an employee, temporary contract worker, or designee responsible for the conduct of the study)

14. Has previously received treatment with recombinant leptin (metreleptin or Fc leptin)
