Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This multi-center study will enroll 60 patients with T1D, A1c values between 6.5 to 10%. The patients will be randomized in 1:1 fashion to either TI or NL. Patients who are randomized into the NL arm will continue using their usual prandial insulin dose before meals. Patients who are randomized into the TI arm will be instructed to dose before the meals and take necessary corrections at 1- and 2-hours after meals to optimize PPBG (Table 1B). There will be a total of 7 study visits (screening visit, randomization visit, 2 clinic, and 3 phone visits). There will be a 4-week treatment comparison between TI and NL and 1-week of post-study follow up. (Phone visit; Figure-1). Standard lab tests (A1c, complete metabolic panel {CMP}, complete blood count {CBC}) will be performed at the screening visit.
All patients will use real-time CGM (Dexcom G5®, San Diego, CA), which will be provided at the randomization visit for their day-to-day diabetes care. CGM data will be downloaded at every clinic visit on a secured computer. The data will be analyzed after the study for different primary and secondary end points. All patients will be allowed to keep the CGM after the study is over for their day-to-day diabetes care.

Study Groups

Technosphere insulin (TI, Afrezza) -Treatment arm
Patients who are randomized into the TI arm will be instructed to dose before the meals and take necessary corrections at 1- and 2-hours after meals to optimize PPBG ( post prandial blood glucose)
Technosphere insulin
This multi-center study will enroll 60 patients with T1D, A1c values between 6.5 to 10%. The patients will be randomized in 1:1 fashion to either TI or NL. Patients who are randomized into the NL arm will continue using their usual prandial insulin dose before meals. Patients who are randomized into the TI arm will be instructed to dose before the meals and take necessary corrections at 1- and 2-hours after meals to optimize PPBG (Table 1B). There will be a total of 7 study visits (screening visit, randomization visit, 2 clinic, and 3 phone visits). There will be a 4-week treatment comparison between TI and NL and 1-week of post-study follow up. (Phone visit; Figure-1). Standard lab tests (A1c, complete metabolic panel {CMP}, complete blood count {CBC}) will be performed at the screening visit.
Insulin Aspart ( Novolog) -Control arm
Patients who are randomized into the NL arm will continue using their usual prandial insulin dose before meals.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. Male or female aged 18-70 years,
3. Type 1 diabetes mellitus (T1D) duration more than six months
4. Treatment with multiple daily injections (MDI) for at least three months before screening visit; stable insulin dose for the last one month,
