A Bioequivalence Study Comparing Two Different Strengths Formulations of Insulin Lispro in Patients With Type 1 Diabetes

Study duration per participant is approximately 62 days including a screening period up to 28 days before first dose, 2 periods of 2 days, a wash out period of 5 to 18 days (preferred7 days) and an end of study visit 7 to 14 days after the last dose

• Male or female patients, between 18 and 64 years of age, inclusive, with diabetes mellitus type 1 for more than one year
• Total insulin dose of <1.0 U/kg/day
• Fasting serum C-peptide <0.30 nmol/L at screening
• Glycohemoglobin (HbA1c) ≤75 mmol/mol (≤9%) at screening
• Stable insulin regimen for at least 2 months prior to study (day of insulin regimen switch, with respect to safety of the patient and scientific integrity of the study).
• Patients with anti-insulin antibody titer at screening ≤ 30.0 kU/L
• Body weight between 50.0 kg and 100.0 kg, inclusive, il male , and between 40.0 and 90.0 kg, inclusive, if female, Body Mass Index between 18 and 30.0 kg/m², inclusive

• More than 1 episode of severe hypoglycemia resulting in coma/seizures or requiring assistance of another person, and/or hospitalization for diabetic ketoacidosis in the last 6 months before screening visit.
• Frequent headaches and/or migraine, recurrent nausea and/or vomiting (for vomiting only, more than twice a month).
• Symptomatic postural hypotension, irrespective of the decrease in blood pressure, or asymptomatic postural hypotension defined as a decrease in systolic blood pressure ≥20 mmHg within 3 minutes when changing from supine to standing position.
• Presence or history of drug hypersensitivity, or allergic disease diagnosed and treated by a physician.
• Likelihood of requiring treatment during the study period with drugs not permitted by the clinical study protocol
