August 24, 2021 updated by: Hua Medicine Limited

A 24-week Multi-center, Randomized, Double-blind, Placebo-controlled, Phase III Study to Evaluate the Efficacy and Safety of HMS5552 add-on to Metformin With Additional 28-week Open-label Treatment to Evaluate the Safety in T2DM Subjects

This study evaluates the efficacy and safety and population PK of HMS5552 add-on to Metformin in adult type 2 diabetic subjects. There will be 2 groups in the first 24 weeks, one group will receive HMS5552 plus Metformin, while the other group will receive placebo plus Metformin; after 24 weeks, all subjects will receive HMS5552 plus Metformin for 28 weeks.

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.

Detailed Description

This study is a phase III study in subjects with T2DM. As designed, the study will start with a 4-week, single-blind, placebo run-in period based on diet and exercise interventions for screening eligible subjects, meanwhile, subjects are treated with Metformin (Glucophage) at 1500mg/day as basic therapy throughout the treatment period. 3 weeks after run-in, eligibility is confirmed with required laboratory tests at -5±2 days prior to randomization. The eligible subjects are randomly assigned to HMS5552 75mg BID group or placebo BID group with ratio 1:1 to receive a 24-week double-blind treatment. Then all subjects receive 28-week open-label treatment of HMS5552 75mg BID add-on to Metformin. After 52-week treatment, all investigational drugs should be discontinued, followed by 1 week for safety evaluation. The dosage of Metformin (Glucophage) should be maintained at 1500 mg/day from run-in period to treatment completion.

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
