A Study to Evaluate the Efficacy and Safety of ORMD-0801 (Oral Insulin) in Patients With Type 2 Diabetes Mellitus

Study Overview
=================
Brief Summary
-----------------
This is a four-way (Participant, Care Provider, Investigator, Outcomes Assessor) masked (blinded) study designed to explore the efficacy of ORMD-0801 when given in different regimens across a dose range for up to 12 weeks in subjects with type 2 diabetes mellitus (T2DM).

Detailed Description
-----------------
This study is designed to explore the efficacy of ORMD-0801 when given in different regimens across a dose range for up to 12 weeks in subjects with type 2 diabetes mellitus (T2DM). There are two cohorts in this study. Approximately 360 subjects with T2DM will initially undergo a 2-week, single-blind placebo run-in period (Visits 1 and 2), followed by a 12-week treatment period (Visits 3 through 9). Cohort A will enroll 285 subjects; Cohort B will enroll 75 subjects For 265 of the 285 subjects of Cohort A, the total 12-week treatment period will include a Part 1dose escalation interval (2 weeks, Visits 3 and 4) and a Part 2 stable dose maintenance interval (10 weeks, Visits 5 through 9). In addition, per FDA request, the remaining 20 subjects (of the cohort total of 285 enrolled subjects) will receive excipient-matched placebo in a non-randomized single-blind fashion, TID (3 times per day), according to the same schedule as described above. For Cohort B (75 of the 360 total subjects), the total 12-week treatment period will include a stable dosing period for both Part 1 (2 weeks, Visits 3 and 4) and Part 2 (10 weeks, Visits 5 through 9). Cohort A data will be analyzed after Cohort A data collection has been completed (last subject for Cohort A screened on 7 May 2019). Estimated completion for Cohort A is October 2019. Cohort B data will be analyzed following the release of results from Cohort A.
