Study to Evaluate the Efficacy and Safety of ORMD-0801 in Subjects With Type 2 Diabetes Mellitus

Inclusion Criteria: * Male and female subjects aged 18 - 75 years. * Established diagnosis of T2DM for at least 6 months prior to Screening AND an A1C ≥ 7.5% but ≤ 11.0% at Screening. * On a stable dose of at least one and up to three of the following oral glucose-lowering agents: Metformin, DPP-4 inhibitor, SGLT-2 inhibitor, thiazolidinedione, or sulfonylurea for a period of 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. * Renal function - GFR ≥ 30 ml/min/1.73 m2. * Females of childbearing potential must: * 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: * i. Postmenopausal (defined as at least 12 months with no menses in women ≥45 years of age); OR * ii. Have had a hysterectomy and/or bilateral oophorectomy, bilateral salpingectomy, or bilateral tubal ligation/occlusion at least 6 weeks prior to screening; OR * iii. Have a congenital or acquired condition that prevents childbearing. Exclusion Criteria: Subjects with: * Type 1 diabetes. * A history of diabetes mellitus with ketoacidosis or is assessed by the Investigator as possibly having type 1 diabetes mellitus confirmed by a C-peptide \< 0.4 ng/mL (0.13 nmol/L) at Screening. * Diabetes attributable to other secondary causes (e.g., genetic syndromes, secondary pancreatic diabetes, diabetes due to endocrinopathies, drug- or chemical-induced, and post-organ transplant). * Treatment involving glucosidase inhibitor, insulin secretagogues (other than sulfonylureas), or GLP-1 receptor agonists within 3 months prior to Visit 1. * A history of \>2 episodes of severe hypoglycemia within 6 months prior to Screening. * A history of hypoglycemic unawareness. * A history of unstable angina or myocardial infarction within 6 months prior to Screening, New York Heart Association (NYHA) Grade 3 or 4 congestive heart failure (CHF), valvular heart disease, ventricular cardiac arrhythmia requiring treatment, pulmonary hypertension, cardiac surgery, coronary angioplasty, stroke or transient ischemic attack (TIA) within 6 months prior to Screening. * A history of uncontrolled or untreated severe hypertension defined as systolic blood pressure above or equal to 160 mmHg and/or diastolic blood pressure above or equal to 100 mmHg. A single repeat measurement will be permitted. * Renal dysfunction: GFR \< 30 mL/min/1.73 m2. * Active proliferative retinopathy requiring treatment. * Psychiatric disorders that, per Investigator judgment, may have impact on the safety of the subject or interfere with the subject's participation or compliance in the study. * Laboratory abnormalities at Screening including: * a. C-peptide \< 0.4 ng/mL. * b. Abnormal serum thyrotropin (TSH) levels below the lower limit of normal or \>1.5X the upper limit of normal; a single repeat test is allowable. * c. Elevated liver enzymes (alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP)) \>3X the upper limit of normal; a single repeat test is allowable. * d. Very high fasting triglyceride levels (\>600 mg/dL); a single repeat test is allowable. * e. Any relevant abnormality that would interfere with the efficacy or the safety assessments during study treatment administration. * Positive history of active liver disease (other than non-alcoholic hepatic steatosis), primary biliary cirrhosis, or active symptomatic gallbladder disease. * Positive results for human immunodeficiency virus (HIV) antibodies, hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb), or hepatitis C virus ribonucleic acid (RNA). * Patient has active or history of neoplastic disease (except for adequately treated non-invasive basal cell and/or squamous cell carcinoma or carcinoma in situ of the cervix) within the past 5 years prior to Baseline. * Use of the following medications: * a. History of use of any injectable or inhaled, basal, pre-mixed or prandial insulin (greater than 7 days) within 6 months prior to Screening. * b. Administration of thyroid preparations or thyroxine (except in subjects on stable replacement therapy) within 6 weeks prior to Screening. * c. Requirements (in the last 12 months), or may require, systemic (oral, intravenous, intramuscular) glucocorticoid therapy for more than 2 weeks during the study period. Intra-articular and/or topical corticosteroids are not considered systemic. * d. Use of medications known to modify glucose metabolism or to decrease the ability to recover from hypoglycemia such as oral, parenteral, and immunosuppressive or immunomodulating agents. Inhaled nasal steroids are permissible. * Known allergy to soy. * Involvement in a weight loss program and is not in the maintenance phase, or subject has started weight loss medication (e.g., orlistat or liraglutide) within 3 months prior to Screening. * Prior bariatric surgery. * Subject is pregnant or breast-feeding. * Subject is a user of recreational or illicit drugs or has had a recent history (within 1 year of Screening) of drug or alcohol abuse or dependence. (Note: Alcohol abuse includes heavy alcohol intake as defined by \>3 drinks per day or \>14 drinks per week or binge drinking) at Screening. Occasional intermittent use of cannabinoid products will be allowed provided that no cannabinoid products have been used during the 1 week prior to each visit. * Contraindications to metformin use as per label. * A history of gastrointestinal disorders (e.g. hypochlorhydria) with the potential to interfere with drug absorption. * Any condition or other factor (at the Investigator's discretion) that is deemed unsuitable for subject enrollment into the study.
