Summary

This double-masked placebo-controlled study will include approximately 450 subjects with inadequately controlled T2DM on diet control alone or on diet control and metformin monotherapy. Subjects will undergo an initial 21-day Screening Period, followed by a 26-week Double-Blind Treatment Period and a Double-Blind 26-week Treatment Extension Period.

Description

Screening Period The investigator will review the aim of the study, study procedures, potential risks, and benefits with the volunteers. These subjects will then sign a written informed consent during Screening Visit 1. They will be instructed to return to the clinic 10 days prior to randomization (Visit 1) for Screening Visit 2. At this visit, a continuous glucose monitoring (CGM) sensor will be placed with appropriate instructions by the study team for a 10-day blinded CGM data collection by the site. Subjects will then return to the clinic after 10 days (± 1-day) for removal of the CGM sensor. The subjects will be randomized to one of the three study treatment arms.

26-Week Double-Masked Treatment Period After the Screening Period, subjects will be randomized to 26 weeks of the Double-Blind Treatment Period consisting of ORMD-0801 8 mg (1 x 8 mg capsule), or placebo in a 1:1 randomized fashion. Medication will be administered once daily at night prior to bedtime (between 8 PM to 12 Midnight and no sooner than 1 hour after dinner).

During the Double-Masked Treatment Period commencing at Week 0 (Visit 1, CGM removal), subjects will return to the clinic at the following intervals: Week 6 - Visit 2; Week 12 -Visit 3; Week 18 - Visit 4; Week 24 - Visit 5 (10 days prior to Week 26 for CGM application) and Week 26 - Visit 6 (CGM removal and end of Double-Blind Treatment Period visit).

The visit requiring CGM application will occur 10 days prior to the CGM removal visit within a ± 1-day window

26-Week Double-Masked Treatment Extension Period Following the completion of the Double-Blind Treatment Period, subjects will enter a 26-week Double-Blind Treatment Extension Period. Subjects will remain on the same treatment regimen and continue to receive the same medication for the duration of the Double-Blind Treatment Extension Period. The Extension Period treatment assignments will remain blinded for the duration of the study.

Visits will occur at the following intervals during the 26-Week Double-Masked Treatment Extension Period: Week 30 - (Visit 7); Week 40 - Visit 8; Week 50 - Visit 9 (10 days prior to Week 52 for CGM application); and Week 52 - Visit 10 (CGM removal and end of Double-Blind Treatment Extension Period visit).

The visit requiring CGM application will occur 10 days prior to the CGM removal visit within a ± 1-day window.

All subjects completing the trial will return to the clinic in 2 weeks ± 3 days for a Safety Follow-Up Visit. Subjects withdrawing prematurely from the trial, will have the early termination (ET) visit procedures completed. All patients will continue to be followed in accordance with ITT principles to avoid a loss to follow-up and missing data.

\. Subjects should be on
a. Diet and exercise therapy with no oral or injectable glucose lowering therapy for a period of at least 3 months prior to screening; OR
b. Diet and exercise therapy with a stable dose of metformin only (≥1500 mg or maximal tolerated dose) for a period of at least 3 months prior to Screening
\. Body mass index (BMI) of 25-40 kg/m2 at Screening and stable weight, with no more
than 5 kg gain or loss in the 3 months prior to Screening
\. Females of childbearing potential must
\. Renal function - GFR ≥ 30 ml/min/1.73 m2
a. have a negative serum pregnancy test result at Screening
b. agree to avoid becoming pregnant while receiving IP for at least 30 days prior to IP administration, during the entire study, and for 30 days following their last dose of IP
c. agree to use an acceptable method of contraception at least 30 days prior to IP administration, during the entire study, and for 30 days following their last dose of IP. Acceptable methods of contraception are hormonal contraception (contraceptive pill or injection) PLUS an additional barrier method of contraception such as a diaphragm, condom, sponge, or spermicide
d. In the absence of hormonal contraception, double-barrier methods must be used which include a combination of any two of the following: diaphragm, condom, copper intrauterine device, sponge, or spermicide, and must be used for at least 30 days prior to administration of IP, during the entire study, and for 30 days following their last dose of IP
e. Abstinence (relative to heterosexual activity) can be used as the sole method of contraception if it is consistently employed as the subject's preferred and usual lifestyle and if considered acceptable by local regulatory agencies and ERCs/IRBs. Periodic abstinence (e.g., calendar, ovulation, sympto-thermal, post-ovulation methods, etc.) and withdrawal are not acceptable methods of contraception
f. Females who are not of childbearing potential are defined as
ii. Have had a hysterectomy and/or bilateral oophorectomy, bilateral salpingectomy, or bilateral tubal ligation/occlusion at least 6 weeks prior to screening; OR
