Screening (Visit 1): Informed consent and California Experimental Subjects Bill of Rights will be signed and eligibility confirmed. Eligible subjects will be enrolled at Visit 1. Subjects will come into the clinic in a fasting state for a meal challenge and individual dose of Afrezza during Visits 2 and 3. At the beginning of each visit, before their dose of Afrezza, subjects will have FEV1 measurements taken in the clinic. Each meal challenge will consist of 1 to 2 bottles of nutritional shake to be fully consumed within 15 minutes. The nutritional shake will contain approximately 240 calories, 41 g carbohydrate, 10 g protein, and 4 g fat per bottle. Each Afrezza dose will be administered at the start of the meal challenge. Visit 2: The first dose of Afrezza will be based on the dose of subcutaneous (SC) rapid-acting analogue (RAA) insulin that the subject would normally take, converted according to the guidelines provided in the current Afrezza prescribing information. If subject's normal RAA dose is <4 units or 5 units, subject will be asked to consume enough nutritional shake, per their normal I:C ratio, to cover an RAA dose of 4 units or ?6 units such that their Afrezza dose at Visit 3 is higher than the dose taken at Visit 2. After completing the standardized meal challenge, the Investigator will decide, based on the subject's glucose excursion at Visit 2, if the subject should proceed to Visit 3 where a second dose of Afrezza will be administered. Visit 3: The second dose of Afrezza will be based on the dose of SC RAA that the subject would normally take, converted by multiplying their RAA dose by 2 and rounding down to the nearest Afrezza cartridge size. Follow-up Visit (Visit 4): Subjects will return for safety assessments, including a final FEV1 measurement, 24 to 72 hours after their last dose of Afrezza.
