简要总结
To compare the efficacy of ORMD-0801 to placebo in improving glycemic control as assessed by A1C in inadequately controlled T2DM subjects on diet control alone or on diet control and metformin monotherapy or two or three oral glucose-lowering agents.
To assess the safety of repeat administration of ORMD-0801 in inadequately controlled T2DM subjects on on diet control alone or on diet control and metformin monotherapy or two or three oral glucose-lowering agents.
详细描述
In this randomized, double-blind, double dummy, placebo-controlled study, approximately 608 eligible subjects with type 2 diabetes and inadequate control on diet control alone or on diet control and metformin monotherapy or on at least two and up to 3 oral glucose-lowering agents will undergo an initial 21-day Screening Period, followed by a 6 month Double-Blind Treatment Period and a 6 month Double-Blind Treatment Extension Period.
Screening Period:
The Investigator will review the aim of the study, study procedures and potential risks and benefits. These subjects will then sign a written informed consent during the Screening Visit 1. They will be scheduled to return to the clinic 10 days prior to randomization for Screening Visit 2. At this visit, a CGM sensor will be placed with appropriate instructions by the study team for a 10-day blinded continuous glucose monitoring (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 arms of the study treatment.
6 month Double-Blind Treatment Period: After the Screening Period, subjects will be randomized to 6 months of the Double-Blind Treatment Period. In a double-blind, double dummy randomization scheme, subjects will either receive ORMD-0801 administered once-daily at night (1 x 8 mg capsule between 8 PM to 12 Midnight and no sooner than 1 hour after dinner) or ORMD-0801 8 mg (1 x 8 mg capsule) administered twice daily, each morning approximately 45 minutes (±15 minutes) prior to breakfast and each night prior to bedtime (between 8 PM to 12 Midnight and no sooner than 1 hour after dinner); or matching placebo. Subjects will receive 1 capsule approximately 45 minutes (±15 minutes) prior to breakfast and 1 capsule between 8 PM to 12 Midnight and no sooner than 1 hour after dinner.
During the Double-Blind Treatment Period commencing at Week 0 (Visit 1, CGM removal), subjects will return to the clinic every six weeks.

入选标准
- •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 two and up to three of the following oral glucose-lowering agents: Metformin, DPP-4 inhibitor, SGLT-2 inhibitor, thiazolidinedione, insulin secretagogue, or oral GLP-1 receptor agonists 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 - eGFR ≥ 30 ml/min.
- •Females of childbearing potential must:
- •have a negative serum pregnancy test result at Screening.
- •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.
- •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
- •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.
- •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
- •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.
