Enavogliflozin vs. Pioglitazone on Glucose and Atherosclerosis

May 2, 2026 updated by: Soo Lim, Seoul National University Bundang Hospital

Comparing Enavogliflozin and Pioglitazone as Add-ons to Metformin With/Without Dipeptidyl Peptidase-4 Inhibitors in Type 2 Diabetes

The current study aimed to thoroughly compare a thiazolidinedione and an sodium-glucose cotransporter-2 (SGLT2) inhibitor regarding various clinical issues including atherosclerosis. Enavogliflozin is compared to Pioglitazone in the glucose-lowering effects of adding to the treatment of patients with type 2 diabetes whose HbA1c levels are not controlled by Metformin with or without DPP-4 inhibitors. Additionally, the study will compare changes in other metabolic or cardiovascular risk factors, such as triglycerides, high density lipoprotein cholesterol (HDLc), uric acid, blood pressure, and inflammatory markers, between the two drugs.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers
