Investigational Study of Delayed Release Metformin

Paused · Phase 3 · Has a placebo group

Conditions studied: Diabetes Mellitus, Type 2

In brief

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.

Who can join

Age: 18 and older, up to 100. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Is male or female and at least 18 years old
• Has body mass index 20.0 to 45.0 kg/m2 (inclusive)
• Has T2DM
• Has HbA1c of 7.0% to 9.5%, inclusive, at Visit 1A and HbA1c value of 7.0% to 10.5%, inclusive, at Week -2 (Visit 3/3A as applicable)
• Has an eGFR value of ≥30 mL/min/1.73 m2 based on the CKD-EPI equation at Visit 1A and Visit 3/3A (Week -2)
• Stable treatment with a metformin preparation or a combination product containing metformin for 8 weeks prior to Visit 1A
• If treated with the following medications, must be on a stable regimen for a minimum of 6 weeks prior to Visit 1B
• Drugs known to affect body weight, including prescription medications (e.g., phentermine, phentermine/topiramate, orlistat, lorcaserin, bupropion/naltrexone) and over-the-counter anti-obesity agents
• Hormone replacement therapy (female patients) and testosterone (male patients)
• Oral contraceptives (female patients)
• Antihypertensive agents including ACEi/ARB
• Lipid-lowering agents
• Thyroid replacement therapy
• Antidepressant agents
• Ability to understand and willingness to adhere to protocol requirements

You may not qualify if…

• Is currently on dialysis, has been on any dialysis within 1 year of Visit 1B, or is expected to undergo dialysis during the study period
• Has a history of lactic acidosis
• Has a fasting plasma glucose (FPG) value >240 mg/dL (>13.3 mmol/L) at Week -2 (Visit 3/3A as applicable)
• An alanine aminotransferase or aspartate aminotransferase result >2.5 × upper limit of normal (ULN) or a bilirubin result >1.5 × ULN at Visit 1B or Visit 3/3A (Week -2) (except in case of documented Gilbert's syndrome)
• Has a fasting plasma lactate value >2 mol at Visit 1B
• Has a bicarbonate value ≤20 mEq/L at both Visit 1A and 1B. If bicarbonate value is <20 at Visit 3/3A or 4, patient may be excluded if the investigator considers this clinically significant
• A history of >5% weight change within 12 weeks prior to Visit 1A
• Has mean BP measurements >180 mmHg (systolic BP) or >100 mmHg (diastolic BP) at Visit 1A or Visit 3/3A, which can be rechecked within 1 week (Note: re-screening is allowed 6 weeks after initiation/modification of antihypertensive agents if the patient is screen failed due to BP only)
• Oral antidiabetic agent or insulin use that is not stable for 8 weeks prior to randomization (i.e., change in oral medication dose or basal insulin dose increased or decreased by more than 20% during the 8 weeks prior to Visit 4 [Day 1])
• Has been treated, is currently being treated, or is expected to require or undergo treatment with any of the following excluded medications:
• Prescribed metformin preparation after initiation of metformin washout following Visit 1B
• Greater than 10 consecutive days of systemic corticosteroids by oral, intravenous, or intramuscular route within 12 weeks of Visit 1B; inhaled, intranasal, ophthalmic, topical, or intra-articular corticosteroids are not exclusionary
• Planned use of proton pump inhibitors after Visit 2 (Week -6); such use could potentially affect the DR and PK of Metformin DR. Proton pump inhibitor treatment may be replaced by other treatment (such as H2 receptor antagonists [excluding ranitidine], or calcium carbonate antacids) prior to Visit 4 (Day 1), if appropriate per the judgment of the Investigator
• Cationic drugs that are eliminated by renal tubular secretion (e.g., amiloride, digoxin, morphine, procainamide, flecainide, quinidine, quinine, ranitidine, triamterene, trimethoprim, and vancomycin) within 1 week of Visit 3 (Week 2)
• Iodinated contrast dye within 1 week prior to Visit 3 (Week -2)
• Investigational drug within 8 weeks (or 5 half-lives of the investigational drug, whichever is greater) of the date of the first dose of randomized study medication
• Metformin DR or double-blind matching placebo for Metformin DR at any time prior to Visit 1B
• Has a clinically significant medical condition as judged by the Investigator that could potentially affect study participation and/or personal well-being, including but not limited to the following conditions:
• Hepatic disease
• 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. Prior or expected surgical gastrointestinal procedure that may impact the gut hormonal response to study medication such as gastric bypass surgery or gastric banding surgery iii. Active diagnosis of pancreatitis c. Endocrine disorder other than T2DM or hypothyroidism on replacement therapy d. Cardiovascular disease, including history of stroke, decompensated heart failure New York Heart Association Class III or IV, myocardial infarction, unstable angina pectoris, or coronary arterial bypass graft or angioplasty within 3 months prior to Visit 1A (screening) e. Central nervous system diseases such as epilepsy f. Psychiatric or neurological disorders that in the Investigator's opinion would cause the patient to be noncompliant with study procedures g. 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
• 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)
• Has a history of diabetic ketoacidosis or hyperosmolar non-ketotic hyperglycemia within 1 year prior to Visit 1B
• A physical, psychological, or historical finding that, in the Investigator's opinion, would make the patient unsuitable for the study
• 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
