NCT07628985

Brief Summary

The goal of this clinical trial is to evaluate the efficacy and safety of Bofanglutide (GZR18) compared with Semaglutide in Latin American adults with type 2 diabetes mellitus who have inadequate glycemic control while receiving stable metformin monotherapy. The main questions it aims to answer are: Does Bofanglutide (GZR18) provide glycemic control comparable to Semaglutide based on changes in HbA1c? Is Bofanglutide (GZR18) safe and well tolerated in the study population? Can participants achieve glycemic targets and improve metabolic outcomes during treatment? Researchers will compare participants receiving Bofanglutide (GZR18) with participants receiving Semaglutide to evaluate their effects on glycemic control, metabolic outcomes, safety, quality of life, and treatment satisfaction. Participants will: Be randomly assigned in a 1:1 ratio to receive Bofanglutide (GZR18) or Semaglutide. Continue stable metformin monotherapy during the study. Receive subcutaneous study treatment with dose escalation according to the study protocol. Participate in 30 weeks of active treatment. Attend scheduled study visits, laboratory assessments, and safety evaluations. Complete questionnaires related to quality of life and treatment satisfaction.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Adults aged 18 years and older who agree to participate in the study by voluntarily signing the Informed Consent Form.
  • Adult participants of either male or female sex.
  • Diagnosis of type 2 diabetes mellitus (T2DM) with a duration greater than 6 months, established according to the diagnostic and classification criteria for diabetes mellitus of the World Health Organization (WHO) in 1999, as well as the supplementary WHO diagnostic criteria of 2011, and in accordance with the widely accepted clinical criteria of the American Diabetes Association.
  • Background treatment with metformin monotherapy, at a stable dose for at least 90 days prior to screening, at a dose ≥1500 mg/day or at the maximum tolerated dose (MTD; ≥1000 mg/day), with no planned changes during the study.
  • HbA1c determined by central laboratory during the screening period ≥7.0% and ≤10.5%.
  • Fasting plasma glucose (FPG) during screening \<270 mg/dL.
  • Body mass index (BMI) ≥27 kg/m².
  • Stable body weight prior to screening, defined as a change ≤5% in body weight during the previous 3 months.
