a study to evaluate the efficacy and safety of ormd-0801 (oral insulin) in patients with type 2 diabetes mellitus

Conditions: T2DM (Type 2 Diabetes Mellitus)

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).

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.

a single repeat test is allowable. 5. any relevant abnormality that would interfere with the efficacy or the safety assessments during the study treatment administration. * positive history of active liver disease (other than non-alcoholic hepatic steatosis), including chronic hepatitis b or c, primary biliary cirrhosis, or active symptomatic gallbladder disease. * positive history of hiv. * use of the following medications: 1. history of any basal, pre-mix or prandial insulin (greater than 7 days) within 6 months prior to screening. 2. administration of thyroid preparations or thyroxine (except in subjects on stable replacement therapy) within 6 weeks prior to screening. 3. administration of systemic long-acting corticosteroids within two months or prolonged use (more than one week) of other systemic corticosteroids or inhaled corticosteroids (if daily dosage is \> 1,000 μg equivalent beclomethasone) within 30 days prior to screening. intra-articular and/or topical corticosteroids are not considered systemic. 4. use of medications known to modify glucose metabolism or to decrease the ability to recover from hypoglycemia such as oral, parenteral, and inhaled steroids (as discussed above), and immunosuppressive or immunomodulating agents. * known allergy to soy. * subject is on a weight loss program and is not in the maintenance phase or subject has started weight loss medication (e.g., orlistat or liraglutide), within 8 weeks prior to screening. * subject has had bariatric surgery. * subject is pregnant or breastfeeding. * 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.
