Clinical trial Recruiting at 2 sites Phase 4 Interventional Ages 18 and up

Cofrogliptin every two weeks added to metformin and dapagliflozin versus daily linagliptin for type 2 diabetes

Official title: Cofrogliptin Once Every 2 Weeks as Add-on Therapy to Metformin and Dapagliflozin Versus Daily Linagliptin in Patients With Type 2 Diabetes: A Multicenter, Randomized, Open-Label, Active-Controlled, Non-inferiority Trial

Run by Huazhong University of Science and Technology · NCT07019012 · Data updated 2026-11-12

This trial will test whether adding cofrogliptin every two weeks to metformin and dapagliflozin lowers HbA1c better than adding daily linagliptin in adults with type 2 diabetes whose blood sugar is not controlled on metformin plus an SGLT2 inhibitor.

Is this trial a fit for you?

Likely a good fit

Adults (≥18 years) with type 2 diabetes who have been on dapagliflozin 10 mg daily and a stable dose of metformin for ≥12 weeks, with HbA1c between 7.0% and 10.0%, eGFR ≥60 ml/min/1.73 m2, BMI ≤40 kg/m2, and willingness to perform home glucose monitoring are the ideal candidates.

Probably not a fit

People with type 1 diabetes, those with HbA1c outside the 7.0–10.0% range, significant renal impairment (eGFR <60), or who are not already on metformin plus an SGLT2 inhibitor are unlikely to benefit from this protocol.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This phase 4 interventional comparison assigns adults with type 2 diabetes who remain above target HbA1c on stable metformin and dapagliflozin to receive either cofrogliptin every two weeks or daily linagliptin in addition to their existing therapy. The primary outcome is the change in glycated hemoglobin (HbA1c) from baseline to 24 weeks. Participants will be followed for safety and changes in fasting plasma glucose and other metabolic measures, with visits at Wuhan University-affiliated hospitals. Eligible participants must have been on dapagliflozin 10 mg and stable metformin for at least 12 weeks and meet specified HbA1c, BMI, and kidney function limits.

Why it matters

Potential benefit: If successful, adding cofrogliptin every two weeks could improve or match HbA1c control while offering less frequent dosing compared with a daily DPP-4 inhibitor.

How similar studies have gone: Daily DPP-4 inhibitors like linagliptin have established efficacy for lowering HbA1c, but cofrogliptin given every two weeks is a newer dosing approach with limited published evidence to date.

* Have been on initial SGLT2i monotherapy (dapagliflozin) at a dose of 10 mg daily for at least 12 weeks.
* Have received metformin treatment for ≥12 weeks, with a stable dose maintained during the screening period (≥1500 mg/day if tolerable or at the maximum tolerated dose (\<1500 mg/day but ≥1000 mg/day), and no dosage adjustment).
* HbA1c levels within the range: 7.0% \< HbA1c ≤ 10.0%.

* Concurrent immune system diseases or currently receiving systemic corticosteroid therapy.
* Changes in thyroid hormone dosage within the last 6 weeks, or any other uncontrolled endocrine or metabolic disorder outside of T2DM.
* Alcohol or drug abuse within the last 3 months that may reduce trial compliance, or any chronic condition deemed by the investigator as likely to reduce study compliance or medication adherence.
* Known allergy to the trial medication components or other chemically similar drugs or excipients.
* Pregnant women, women planning pregnancy during the study or breastfeeding, subjects unwilling to use reliable contraception (including condoms, spermicides, or intrauterine devices) from signing the informed consent form until 28 days after the last dose of trial medication, or women planning to use progesterone-containing contraceptives during this period. Men with plans for conception during the study.
