This is an interventional basic science trial for Type 1 Diabetes Mellitus Read More

Inclusion criteria :

• Male or female patients, between 18 and 65 years of age, inclusive, with diabetes mellitus type 1 for more than one year, as defined by the American Diabetes Association.

• Body weight between 50.0 and 95 kg, inclusive, body mass index between 18.5 and 29 kg/m², inclusive.
• Fasting serum C-peptide <0.3 nmol/L.
• Glycohemoglobin (HbA1c) ≤75 mmol/mol (≤9%).
• Stable insulin regimen for at least 2 months prior to study (with respect to safety of the patient and scientific integrity of the study).
• Certified as otherwise healthy for type 1 diabetes mellitus patient by assessment of medical history and physical examination (cardiovascular system, chest and lungs, thyroid, abdomen, nervous system, skin and mucosae, and musculoskeletal system), unless the Investigator considers any abnormality to be clinically irrelevant and not interfering with the conduct of the study (with respect to safety of the subject and scientific integrity of the study).
• Having given written informed consent prior to undertaking any study-related procedure.
• Non-smoking at least for the last 6 months before screening (to be confirmed by urine cotinine <500 µg/L).
• Pulmonary function test at screening: forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) >70% of the individual prediction according to the equation of the Third National Health and Nutrition Examination Survey (NHANES III).

Exclusion criteria:

• 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 severe headaches and/or migraine, recurrent nausea and/or vomiting (more than twice a month).
• Presence or history of drug hypersensitivity, or allergic disease diagnosed and treated by a physician.
• History or presence of drug or alcohol abuse (alcohol consumption more than 40 g per day).
• If female, pregnancy (defined as positive beta-human chorionic gonadotropin [β-hCG] blood test), breastfeeding at screening and before any treatment periods (defined as positive β-hCG urine test).
• Any medication (including St John's Wort) within 14 days before inclusion or within 5 times the elimination half-life or PD half-life of the medication, with the exception of insulins, thyroid hormones, lipid-lowering, and antihypertensive drugs and if female with the exception of hormonal contraception or menopausal hormone replacement therapy; any vaccination within 28 days before inclusion.
• Presence or history of any acute or chronic obstructive bronchopulmonary disease including chronic obstructive pulmonary disease, asthma, and cancer.
• Upper respiratory tract infection within 8 weeks before screening.
• Known hypersensitivity to insulin lispro or Afrezza Technosphere insulin and excipients.
• Inability, in the opinion of the Principal Investigator or a designee, to adequately inhale Afrezza powder.
• Any history or presence of deep leg vein thrombosis or a frequent appearance of deep leg vein thrombosis in first-degree relatives (parents, siblings, or children).
