We conducted a 24-week, multicentre, double-blind, randomized study with a
28-week extension to compare the efficacy and safety of anagliptin and
sitagliptin as an add-on to metformin in patients with type 2 diabetes. Patients

Clinical Trials Related to Metformin
A Study to Evaluate the Effect of Multiple Doses of Isavuconazole on the Pharmacokinetics of Metformin [Completed]
The purpose of this study is to assess the effect of multiple doses of isavuconazole on the
pharmacokinetics of a single dose of metformin. Safety and tolerability of isavuconazole
will be assessed alone and in combination with metformin.
Crossover Study to Evaluate the Comparative Bioavailability of Two Fixed Dose Combination Tablet Formulations of Extended Release Metformin and Extended Release Glimepiride in Health Volunteers [Terminated]
This is a an open-label, randomized, single dose, four-way crossover, multi-stage study
enrolling 20 healthy adult male and female subjects per part. This study consists of two
separate parts (Part A and B) with each part comprising four treatment periods. Each subject
will participate in all four treatment periods per part; Subjects may not enrol in both
Parts A and B.
This study is being conducted to compare the pharmacokinetics (PK) of two extended release
fixed dose combinations (FDC) oral formulations of metformin and glimepiride at two doses,
500mg/1mg and 1000mg/2mg, with each FDC formulation to be administered orally as a single
dose and compared with the commercially available formulations of metformin extended release
(XR) (GLUCOPHAGE ™ Sustained Release [SR]) and glimepiride immediate release (IR) (AMARYL
Part A of study will evaluate the bioavailability of a formulation comprising a film coated
tablet containing release controlling polymers; and Part B will evaluate the bioavailability
of a formulation comprising a tablet coated with release controlling polymers.
In each part there will be 4 treatment periods. During each period, subjects will be
randomized sequentially to receive a single dose of a reference treatment of 500 mg
metformin XR / 1 mg glimepiride IR; and a reference treatment of 1000 mg metformin XR / 2 mg
glimepiride IR; and an FDC tablet containing 500 mg metformin XR and 1 mg glimepiride XR;
and an FDC tablet containing 1000 mg metformin XR and 2 mg glimepiride XR. Serial PK sampling
for up to 36 hours and safety assessments will be performed. Each period will be separated
by a washout period of at least 5 days and a follow-up visit will occur 14 days after the
last dose of study drug.
A Study Comparing the Amount of Metformin and After Taking a Combination Tablet vs. Separate Tablets [Completed]
An Extension Protocol to Evaluate Dose Comparisons of Leucine-Metformin Combinations in Type 2 Diabetic Patients [Active, not recruiting]
Study NS-0100-01E is an extension of Study NS-01-0100 designed to assess safety and longer
term effect (i. e., additional 8 weeks) of various fixed-dose leucine and metformin
combinations (NS-0100) versus standard metformin monotherapy on glycemic control in subjects
with type 2 diabetes using HbA1c as the primary endpoint.
Clinical Trial to Evaluate Safety and pK Profile of Metformin Glycinate in Healthy Volunteers [Completed]
Metformin Glycinate is a novel biguanide compound developed as a potential candidate for the
treatment of type 2 diabetes. Metformin Glycinate was found to improve metabolic control in
naive patients with type 2 diabetes.
The objective of this study is to evaluate the safety, tolerability and pK profile of
Metformin Glycinate 620 mg QD, 1240 mg QD, 2480 mg QD, after administration of one single
dose, in step A. In step A will be included 25 volunteers.
In step B the objective is to evaluate Safety, tolerability and pK profile of Metformin
Glycinate 620 mg BID, after administration of multiple dose during 8 days. In step B will be
included 24 volunteers.

Adherence to a diabetic diet is an important aspect of controlling elevated blood sugar in patients with diabetes. The American Diabetes Association (ADA) has provided guidelines for a diabetic diet. The ADA diet is a balanced, nutritious diet that is low in fat, cholesterol, and simple sugars. The total daily calories are evenly divided into three meals. In the past two years, the ADA has lifted the absolute ban on simple sugars. Small amounts of simple sugars are allowed when consumed with a complex meal.
