Investigational Study of Delayed Release Metformin (DREAM-T2D)

Randomized, Multicenter, Double-blind, Parallel-Group, Placebo & Comparator-Controlled Study to Compare the Glycemic Effects, Safety & Tolerability of Metformin Delayed-Release Tablets in Patients With Type 2 Diabetes Mellitus

In Phase 1 and 2 studies already conducted, Metformin DR, with its targeted delivery to the distal small intestine, has shown the potential to be a safe and effective way to improve glycemic control in patients with T2DM and CKD with less systemic metformin exposure. The primary purpose of this Phase 3 clinical study is to collect pivotal data confirming the safety and efficacy of Metformin DR in T2DM patients with varying renal function from normal up to CKD3B.

Study Overview

• Status: Suspended
• Conditions: Diabetes Mellitus, Type 2
• Intervention / Treatment: Drug: Metformin DR; Drug: Metformin IR placebo; Drug: Metformin DR Placebo; Drug: Metformin IR

Detailed Description

The study is a multicenter, international study with a 28 week randomized, double blind parallel group, placebo and active comparator controlled period and a 24 week open label extension period in patients with T2DM who are treated with metformin at the time of study screening.

Approximately 675 patients will be randomly assigned to 1 of 3 treatment groups. The study will assess change in HbA1c through 28 weeks for Metformin DR compared to placebo as a primary endpoint. In addition, assessments of change in HbA1c for Metformin DR compared to Metformin IR and assessment of absolute change in HbA1c will be evaluated in the study.

Screening and Run-in Period:

The study will include an up to 10-day screening period, an 4 to 8-week metformin washout period, and a 2-week single blind (patient blinded) placebo run-in period.

Treatment Period:

Patients that are determined eligible based upon the screening and run-in criteria will enter the 28-week double-blind treatment period. During the double-blind treatment period, patients will be randomly assigned to 1 of 3 treatment groups (Group A, B, or C) in a 1:1:1 ratio. The 3 treatments are Metformin DR (1800 mg Metformin DR with matching placebo for Metformin IR), Metformin IR (1500 mg Metformin IR with matching placebo for Metformin DR), and placebo (matching placebo for Metformin IR with matching placebo for Metformin DR). For those patients randomized to Metformin IR, their Metformin IR dose will be titrated to prevent gastrointestinal intolerability:

Open Label Extension Period:

Upon completion of the 28 week treatment patients will be eligible for an additional 24 weeks of open label extension period where assigned study treatment will continue and additional efficacy, safety and tolerability data will be collected and analyzed.

    1. Hepatic disease
    2. Gastrointestinal disease, including but not limited to:

    i. History or presence of inflammatory bowel disease or other severe gastrointestinal disease, particularly those that may impact gastric emptying, such as gastroparesis and pyloric stenosis ii.

Organ transplantation h. Chronic or acute infection requiring systemic antibiotic treatment i. Orthostatic hypotension or syncope j. Active malignancy within the past 5 years with exception of basal cell and squamous cell carcinoma

12. Known allergy or hypersensitivity to Metformin DR, Metformin IR, or placebo or any inactive component of study medication, active comparator, or placebo, unless the reaction is deemed irrelevant to the study by the Investigator (prior history of gastrointestinal intolerance to metformin is not exclusionary)
13. Has a history of diabetic ketoacidosis or hyperosmolar non-ketotic hyperglycemia within 1 year prior to Visit 1B
14. A physical, psychological, or historical finding that, in the Investigator's opinion, would make the patient unsuitable for the study
15. Any verified clinically significant abnormality identified on physical examination, laboratory tests, ECG, vital signs, or any adverse event (AE) at the time of Visit 1B through Visit 4 that, in the judgment of the Investigator or any Sub-investigator, would preclude safe completion of the study or constrains efficacy assessment
16. Currently abuses drugs or alcohol or has a known history of abuse that in the Investigator's opinion would cause the patient to be noncompliant with study procedures
17. Had a blood transfusion or experienced significant blood loss (i.e., >500 mL), including loss due to blood donation, within 8 weeks prior to Visit 1B, or is planning to donate blood or have a blood transfusion during the study
