A Study to Compare ORMD-0801 Once Daily to ORMD-0801 Three Times Daily in Subjects With Type 1 Diabetes

This study is a Phase 2 randomized, crossover study comparing ORMD-0801 given QD versus TID in subjects with T1D. Subjects with T1D will have a screening visit (Visit 1) during which they will be required to review and sign the informed consent form. Medical history and demographics will be collected. Vital signs will be measured, physical exam will be performed, and blood and urine samples will be collected for hematology/chemistry/urinalysis. Eligible subjects will be scheduled to return to the clinic in 1 week (Visit 2). Subjects fulfilling all inclusion/exclusion criteria will have a CGM placed, provided with a diary, dispensed Placebo capsules and asked to return to the clinic in 10 Days (Visit 3, Day 1) for randomization. At Visit 3, data from CGM will be downloaded and diaries will be collected. Blood samples will be collected in fasting for chemistry and HbA1c. Subjects will be randomized to receive either ORMD-0801 24 mg given once daily at bedtime, or ORMD-0801 8 mg given three times a day, 45-90 minutes before meals.

Subjects will be instructed to continue their normal diet, and to adjust their basal and bolus insulin in the normal fashion. Subjects will be instructed to return to the clinic 10 days before Visit 5 (Visit 4, Day 18). At Visit 4, compliance will be assessed, IMP and diary dispensed and the CGM will be placed. Subjects will be instructed to return to the clinic in 10 days for Visit 5 (Day 28). At Visit 5 a fasting blood sample for chemistry panel and HbA1C will be drawn and after the diary has been collected and the CGM monitor removed, they will be crossed over to the alternate treatment regimen. IMP will be dispensed, and the subject will be asked to return 10 days before Visit 7 for Visit 6 (Day 46). At Visit 6, compliance will be checked, IMP and diary will be dispensed and the CGM will be placed. Subjects will be instructed to return in 10 days for Visit 7 (Day 56). At Visit 7 the CGM will be removed, compliance checked, the diary will be collected, and a blood sample will be drawn for a chemistry panel and HbA1C. A physical examination will be performed, and the subject will exit the study. Subjects will be provided with diaries at Visits 2, 4 and 6, and will be asked to capture the amount of basal and bolus exogenous insulin administered each day and calculate their carbohydrate count for all meals and snacks over the 10-day CGM monitoring period. Diaries will be collected at Visits 3, 5 and 7.

Inclusion criteria

• Male and female subjects aged 18 and older.
• Body mass index (BMI) of 19-30 kg/m2 at Screening and stable weight, with no more than 5 kg gain or loss in the 3 months prior to Screening.
• T1D subjects must have:

• A documented history of type 1 diabetes for at least 6 months
• Should be on an MDI regimen
• C peptide levels of ˂ 0.7 ng/mL
• HbA1C ≥ 6.5% to ≤10%
• Females of childbearing potential must have a negative serum pregnancy test result at Screening.
• Females who are not of childbearing potential are defined as:

• post-menopausal (defined as at least 12 months with no menses in women ≥45 years of age) or
• has had a hysterectomy and/or bilateral oophorectomy, or had bilateral tubal ligation or occlusion at least 6 weeks prior to Screening
• Subjects who are of childbearing potential must:

a. agree to remain abstinent from heterosexual activity† or agree to use (or have their partner use) acceptable contraception to prevent pregnancy within the projected duration of the trial and for 14 days after the last dose of blinded investigational product. Two methods of contraception will be used to avoid pregnancy. Acceptable combinations of methods include: i. Use of one of the following double-barrier methods: diaphragm with spermicide and a condom; cervical cap and a condom; or a contraceptive sponge and condom ii. Use of hormonal contraception (any registered and marketed contraceptive agent that contains an estrogen and/or a progestational agent [including oral, subcutaneous, intrauterine and intramuscular agents, and cutaneous patch]) with one of the following: diaphragm with spermicide; cervical cap; contraceptive sponge; condom; vasectomy; or IUD. iii. Use of an IUD with one of the following: condom; diaphragm with spermicide; contraceptive sponge; vasectomy; or hormonal contraception (see above).

iv. Vasectomy with one of the following: diaphragm with spermicide; cervical cap; contraceptive sponge; condom; IUD; or hormonal contraception (see above).

†Abstinence can be used as the sole method of contraception if it is in line with the subject's preferred and usual lifestyle and if considered acceptable by local regulatory agencies and ethics committees. Periodic abstinence (e.g., calendar, ovulation, sympto-thermal, post-ovulation methods, etc.) and withdrawal are not acceptable methods of contraception.

Exclusion criteria

• Clinical diagnosis of type 2 diabetes;
• Evidence of unawareness of hypoglycemia unawareness, a documented plasma glucose ≤50 mg/dL in the absence of symptoms of hypoglycemia at Screening.
• FPG >300 mg/dL at Screening; a single repeat test is allowable.
• Use of the following medications:

• Administration of thyroid preparations or thyroxine (except in subjects on stable replacement therapy) within 6 weeks prior to Screening.
• 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.
• Laboratory abnormalities at Screening including:

• Abnormal serum thyrotropin (TSH) levels below the lower limit of normal or >1.5X the upper limit of normal
• Elevated liver enzymes (alanine transaminase (ALT), alanine aminotransferase (AST), alkaline phosphatase) >2X the upper limit of normal.
