• Official Title: A Placebo-controlled, Multi-center, Randomized, Phase 2b Study to Evaluate the Efficacy and Safety of ORMD-0801 in Type 2 Diabetes Mellitus Patients With Inadequate Glycemic Control on Oral Therapy
• 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 1"dose 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.

• Study Type: Interventional
• Study Phase: Phase 2

Study Design

Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Masking Description:

Single-Blind Placebo Run-in (Masking will be with Participant):

During the placebo run-in period, subjects will self-administer blinded placebo study medication at night prior to bedtime (@10 PM ± 90 min. each night, no sooner than 2 hrs. after dinner). Outpatient glycemic levels and adverse events will be measured using self-monitored blood glucose (SMBG) and recorded in a diary. Treatment Period (Masking: Participant, Care Provider, Investigator, Outcomes Assessor) There are 2 Cohorts, A and B.

Part 1 In the first 2 weeks of active treatment, subjects will receive double-blind therapy according to their randomized regimen (placebo or ORMD-0801) to be taken QHS (bedtime), BID (2 X / day) or TID.

Part 2 Subjects will remain on fixed doses of ORMD-0801 or matched placebo for 10 weeks. Doses will not be adjusted unless clinically indicated for adverse events or hypoglycemia. Treatment arms will consist of subjects receiving ORMD-0801 QHS, BID, and TID versus placebo.

Primary Purpose: Treatment

• Condition: T2DM (Type 2 Diabetes Mellitus)

Intervention

• Drug: Cohort A: ORMD-0801

  Part 1 In the first two weeks of active treatment (Part 1) subjects will receive double-blind therapy according to their randomized regimen (placebo or ORMD-0801) to be taken QHS, BID or TID. Subjects will undergo a step-wise dose escalation from a starting dose of 16 mg (Visit 3), to 24 mg (Visit 4), to a top dose of 32 mg (Visit 5 onward). Subjects will then enter Part 2.

  Part 2:

  During Part 2, subjects will remain on fixed doses of ORMD-0801 (or matched placebo) for 10 weeks. Doses will not be adjusted unless clinically indicated for adverse events or hypoglycemia.

  Other Name: Oral Insulin
• Drug: Placebo oral capsule
  Placebo provided QHS, BID, TID
  Other Name: SBTI, disodium EDTA, fish oil, aerosil, and TWEEN 80.
• Drug: Cohort B: ORMD-0801

  Part 1 In the first two weeks of active treatment, subjects will receive double-blind therapy according to their randomized regimen (ORMD 0801 8 mg or 16 mg, or matched placebo) to be taken QHS or BID. Subjects will then enter Part 2 at the same dose and regimen administered in Part 1.

  Part 2 Subjects will remain on fixed doses of ORMD-0801 (or matched placebo) for 10 weeks. Doses will not be adjusted unless clinically indicated for adverse events or hypoglycemia.
