Inclusion criteria

Subjects with type 1 diabetes mellitus for more than one year with total insulin dose of <1.2 U.kg/day, but otherwise healthy with glycohemoglobin (HbA1c) ≤ 9.0%, stable insulin regimen for at least 2 months prior to study, normal finding in medical history and physical examination.

Exclusion criteria

any history or presence of clinically relevant cardiovascular, pulmonary, gastro-intestinal, hepatic, renal, metabolic (apart from diabetes mellitus type I), hematological, neurological, psychiatric, systemic (affecting the body as a whole), ocular, gynecologic (if female), or infectious disease; any acute infectious disease or signs of acute illness
More than one episode of severe hypoglycemia with seizure, coma or requiring assistance of another person during the past 6 months
Frequent severe headaches and/or migraine, recurrent nausea and/or vomiting (more than twice a month)
Symptomatic hypotension, or asymptomatic postural hypotension defined by a decrease in systolic blood pressure (SBP) equal to or greater than 20 mmHg within three minutes when changing from the supine to the standing position
Presence or history of a drug allergy to clinically significant allergic disease
Likelihood of requiring treatment during the study period with drugs not permitted by the clinical study protocol
Pregnant or breast feeding women
Any medication within 14 days before inclusion, or within 5 times the elimination half-life of that drug, whichever the longest and regular use of any medication other than insulins in the last month before study start with the exception of thyroid hormones, lipid-lowering and antihypertensive drugs, and, if female, with the exception of hormonal contraception or menopausal hormone replacement therapy, any vaccination within the last 28 days.
Positive reaction to any of the following tests: hepatitis B surface (HBs Ag) antigen, antihepatitis B core antibodies (anti-HBc Ab) if compound having possible immune activities, anti-hepatitis C virus (anti-HCV2) antibodies, anti-human immunodeficiency virus 1 and 2 antibodies (anti-HIV1 and anti HIV2 Ab)
History of unexplained pancreatitis, chronic pancreatitis and/or pancreatectomy
