E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy of TAK-875 plus metformin compared with sitagliptin plus metformin on glycemic control as measured by change from Baseline in glycosylated hemoglobin (HbA1c) over a 24-week Treatment Period. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the effect of TAK-875 plus metformin compared with sitagliptin plus metformin on other measures of glycemic control, including clinically meaningful levels of response in HbA1c and fasting plasma glucose (FPG) over a 24-week Treatment Period. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Subject eligibility is determined according to the following criteria:
1. In the opinion of the investigator, the subject is capable of understanding and complying with protocol requirements.
2. The subject or, when applicable, the subject’s legally acceptable representative signs and dates a written, informed consent form and any required privacy authorization prior to initiation of any study procedures.
3. The subject is male or female and 18 years of age or older with a historical diagnosis of T2DM.
4. The subject meets one of the following criteria:
a) The subject has an HbA1c ≥8% and <10.5%, and has been on a stable daily dose of ≥1500 mg (or documented MTD) of metformin for at least 8 weeks prior to Screening. This subject will immediately enter
the Placebo Run-in Period according to Study Schedule A, or;
b) The subject has an HbA1c ≥8% and <10.5%, and has been on a stable daily dose of <1500 mg of metformin without documented MTD for at least 8 weeks prior to Screening. After completing the Screening Visit, these subjects will have their metformin dose immediately increased to ≥1500 mg (or MTD) for an 8- to 12-week Titration/Stabilization Period according to Study Schedule B. Following stable administration of metformin ≥1500 mg (or MTD) for 8 weeks, the subject must qualify for entry into the Placebo Run-in Period by completing the Week -3 procedures and have an HbA1c ≥8% and <10.5%.
5. The subject has had no treatment with antidiabetic agents other than metformin within 8 weeks prior to Screening (Exception: if a subject has received other antidiabetic therapy for ≤7 days within the 8 weeks prior to Screening).
6. The subject has a body mass index (BMI) ≤45 kg/m2 at Screening.
7. Subjects regularly using other nonexcluded medications, must be on a stable dose and regimen for at least 4 weeks prior to Screening. However, as needed (PRN) use of prescription or over-the-counter medications is allowed at the discretion of the investigator.
8. A female subject of childbearing potential who is sexually active with a nonsterilized male partner agrees to routinely use adequate contraception from signing of the informed consent throughout the duration of the study and for 30 days after the last dose of study drug.
9. The subject is able and willing to monitor glucose with a sponsor-provided home glucose monitor and consistently record his or her own blood glucose concentrations and subject diaries. |
|
E.4 | Principal exclusion criteria |
1. The subject has received any investigational compound within 30 days prior to Screening or has received an investigational antidiabetic drug within the 3 months prior to Screening.
2. The subject has been randomized into a previous TAK-875 study.
3. The subject is an immediate family member, study site employee, or is in a dependent relationship with a study site employee who is involved in conduct of this study (eg, spouse, parent, child, or sibling) or may consent under duress.
4. The subject donated or received any blood products within 12 weeks prior to Screening or is planning to donate blood during the study.
5. The subject has a hemoglobin ≤12 g/dL (≤120 g/L) for men and ≤10 g/dL (≤100 g/L) for women at Screening.
6. The subject has systolic blood pressure ≥160 mm Hg or diastolic blood pressure ≥95 mm Hg at Screening Visit. (If the subject meets this exclusion criterion, the assessment may be repeated once at least 30 minutes after the initial measurement and decision will be made on the second measurement.)
7. The subject has history of cancer that has been in remission for <5 years prior to Screening. A history of basal cell carcinoma or stage I squamous cell carcinoma of the skin is allowed.
8. The subject has alanine aminotransferase (ALT) and/or aspartate aminotransferase (AST) levels >2×upper limit of normal (ULN) at Screening.
9. The subject has a total bilirubin level >ULN at Screening. Exception: if a subject has documented Gilbert’s Syndrome the subject will be allowed with an elevated bilirubin level per the investigator’s discretion.
10. The subject has serum creatinine ≥1.5 mg/dL (≥133μmol/L) if male or ≥1.4 mg/dL (≥124 μmol/L) if female nd/or estimated glomerular filtration rate (GFR) <60 mL/min/1.73 m2 at Screening.
11. The subject has uncontrolled thyroid disease as determined by the investigator.
12. The subject has a history of laser treatment for proliferative diabetic retinopathy within 6 months prior to Screening.
13. The subject has a history of pancreatitis.
14. The subject has a history of gastric banding or gastric bypass surgery within one year prior to Screening.
15. The subject has a known history of infection with human immunodeficiency virus (HIV), hepatitis B virus (HBV), or hepatitis C virus (HCV).
16. The subject had coronary angioplasty, coronary stent placement, coronary bypass surgery, myocardial infarction, unstable angina pectoris, clinically significant abnormal electrocardiogram (ECG), cerebrovascular accident or transient ischemic attack within 3 months prior to or at Screening.
17. The subject has a history of hypersensitivity, allergies, or has had an anaphylactic reaction(s) to any component of TAK-875, metformin, or sitagliptin.
18. The subject has a history of drug abuse (defined as illicit drug use) or a history of alcohol abuse within 2 years prior to Screening.
19. The subject received excluded medications prior to Screening or is expected to receive excluded medications as listed in Section 7.5, Excluded Medications.
20. If female, the subject is pregnant (confirmed by laboratory testing, ie, serum/urine human chorionic gonadotropin (hCG), in females of childbearing potential) or lactating or intending to become pregnant before, during, or within 1 month after participating in this study; or intending to donate ova during such time period.
21. The subject is unable to understand verbal or written English or any other language for which a certified translation of the approved informed consent is available.
