About this study

Official title: A Randomized, Double-Blind, Placebo-Controlled Phase II Clinical Trial of MG-ZG122 Humanized Monoclonal Antibody Injection in Adult Subjects With Moderate-to-Severe Asthma to Evaluate Efficacy and Safety

A Randomized, Double-Blind, Placebo-Controlled Phase II Clinical Trial to Evaluate the Efficacy and Safety of MG-ZG122 Humanized Monoclonal Antibody Injection in Asthma Subjects, with Dosing Every 12 or 24 Weeks for 48 Weeks

Read the detailed description

This study is a multicenter, randomized, double-blind, placebo-controlled Phase II study. Approximately 160 adult asthma subjects are scheduled to receive multiple subcutaneous injections (every 12 or 24 weeks for 48 weeks). The study is divided into a screening period (1 week), a run-in period (4 weeks), a treatment period (48 weeks), and a follow-up period (12 weeks).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Annual incidence rate of asthma exacerbations

    Annualized rate of severe asthma exacerbations over 48 weeks of treatment with MG-ZG122 compared to placebo.

    Measured: 48week

Secondary outcomes (4)
  1. Absolute change in FEV1 from baseline

    Absolute change in pre-bronchodilator FEV1 from baseline at Week 12

    Measured: 12week

  2. Absolute change in FEV1 from baseline

    Absolute change in pre-bronchodilator FEV1 from baseline at Week 2424

    Measured: 24week

  3. Hospitalization due to asthma exacerbation events

    Annualized rate of hospitalizations or emergency department treatments due to severe asthma exacerbations during 48 weeks of treatment

    Measured: 48week

  4. Proportion of subjects with asthma exacerbations

    Proportion of subjects who experienced asthma exacerbations during 48 weeks of treatment

    Measured: 48week

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing MG-ZG122 Humanized Monoclonal Antibody Injection in people with Bronchial Asthma, run by Shanghai Mabgeek Biotech.Co.Ltd at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 8 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Annual incidence rate of asthma exacerbations (time frame: 48week). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Jul 2025.
