Efficacy and Safety of Semaglutide Injection vs Ozempic® in Patients With Type 2 Diabetes

July 25, 2025 updated by: Hangzhou Zhongmei Huadong Pharmaceutical Co., Ltd.

A Multicenter, Randomized, Open-label, Parallel-controlled Phase III Clinical Study Comparing the Efficacy and Safety of Semaglutide Injection With Ozempic ® in Patients With Type 2 Diabetes Mellitus Who Have Inadequate Glycemic Control With Metformin

This is a 32-week randomized, open-label, parallel-controlled biosimilar comparison study comparing the efficacy, safety and immunogenicity of the investigational drug and the active comparator in patients with type 2 diabetes mellitus who have inadequate glycemic control with metformin. Eligible participants will be screened and randomized to the experimental group and the active comparator group at a ratio of 1:1 , semaglutide injection or Ozempic® injection abdominal subcutaneous injection will be given according to their groups weekly for 32 weeks. Follow-up for 4 weeks after administration.

Trial product will be add-on to subject's stable pre-trial metformin.

The study included a screening period (up to 2 weeks), run-in period（6 weeks），baseline, administration period(32 weeks), and a follow-up period (4 weeks). The duration of the study will be approximately 44 weeks for a participant.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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
