Original description

The aim of this study is to evaluate the change in glycated hemoglobin (HbA1c) levels of adding cofrogliptin compared to escalation of metformin dose after 24 weeks in type 2 diabetes patients who have failed to achieve adequate glycemic control despite receiving combination therapy with SGLT2i and metformin. Participants will be asked to use either cofrogliptin combined with SGLT2i and metformin or SGLT2i combined with increased dose of metformin.Read full original descriptionShow less

Efficacy and Safety Comparison of Cofrogliptin Add-on Versus Metformin Dose-escalation in Type 2 Diabetes Patients Inadequately Controlled With SGLT-2 Inhibitors Plus Low-Dose Metformin:A Multicenter, Open-Label Trial

The aim of this study is to evaluate the change in glycated hemoglobin (HbA1c) levels of adding cofrogliptin compared to escalation of metformin dose after 24 weeks in type 2 diabetes patients who have failed to achieve adequate glycemic control despite receiving combination therapy with SGLT2i and metformin. Participants will be asked to use either cofrogliptin combined with SGLT2i and metformin or SGLT2i combined with increased dose of metformin.
