Brief summary
This study is a phase Ib/II clinical trial conducted in Chinese adult asthmatic subjects to evaluate the preliminary efficacy and safety of MG-K10 humanized monoclonal antibody injection in the treatment of asthma.
Detailed description
The study was conducted in two phases: the Phase Ib study focused on the safety and tolerability of MG-K10 in adult asthma subjects. Phase II study focused on the preliminary efficacy in adults with moderate to severe asthma.

Intervention model description
About 180 subjects with moderate-to-severe asthma who meet the inclusion criteria will be selected for this study, according to 1:1:1 Randomly assigned to one of the MG-K10 Q2W group, the MG-K10 Q4W group, and the placebo group, with approximately 60 subjects in each group. The Q2W group will receive MG-K10 300mg subcutaneous injection every 2 weeks; Q4W group will receive MG-K10 300mg subcutaneous injection (every 4 weeks) + 2ml placebo subcutaneous injection ; the placebo group will receive 2 ml of placebo subcutaneously administered every 2 weeks. All three groups were followed up for 8 weeks after 24 weeks of treatment.
Eligibility
Inclusion criteria
* Asthma diagnosed according to the 2021 version of the GINA guidelines for at least 1 year; * 1 second forced expiratory volume (FEV1) before randomization before bronchodilator use The measured value is ≤80% of the normal predicted value; * Must have experienced at least one severe acute asthma attack within 12 months outbreak event. * Positive bronchodilator test * Subjects and partners agree to take effective contraceptive measures from signing the Informed Consent Form (ICF) to 6 months after the end of treatment
Exclusion criteria
* Clinical diagnosis of chronic obstructive pulmonary disease (COPD) or other lung diseases that may impair lung function * Subjects with malignant tumor within 5 years * Received biologics with the same therapeutic purpose within 6 months prior to screening, * Women who are breastfeeding or pregnant, or who plan to become pregnant or breastfeeding during the study period;
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Absolute Change from baseline in pre-bronchodilator FEV1 | 12 week | Absolute change from baseline in pre-bronchodilator FEV1 in each study group at 12 week of MG-K10 treatment compared with placebo |
Secondary
| Measure | Time frame | Description |
|---|---|---|

| peak morning and evening expiratory flow (PEF) | 4,8,12,16,20,24,28,32 week | Change from peak morning and evening expiratory flow (PEF) compared with baseline (absolute and percentage) |
| the Annualized rate of severe asthma acute event | 24 weeks and 25 to 32 weeks | The annualized rate of severe asthma acute event within 24 weeks and 25 to 32 weeks of treatment |
| Annualized rate of the event of loss of asthma control (LOAC) | 24 weeks and 25 to 32 weeks | the annualized rate of the event of loss of asthma control (LOAC) at 24 weeks and 25 to 32 weeks of treatment |
| Time of the first severe asthma acute event | 32 weeks | Time of the first severe asthma acute event |
| Time of first loss of asthma control (LOAC) | 32weeks | Time of first loss of asthma control (LOAC) |
| asthma Control Questionnaire 5 (ACQ-5 score 0-30) changes in score | 4, 8, 12, 16, 20, 24, 28, and 32 weeks | There are 5 questions in ACQ5, It is a questionnaire used to evaluate the degree of asthma control. Each question is scored from 0 to 6 (on a 7-point scale) according to its severity. The higher the score, the less satisfactory symptom control |
| Absolute Change from baseline in pre-bronchodilator FEV1 | 4,8,16,20,24,28,32 week | Absolute change from baseline in pre-bronchodilator FEV1 in each study group at 4,8,16,20,24,28,32 week of MG-K10 treatment compared with placebo |

| Incidence of Adverse events (AEs) | 32 weeks | Incidence of AEs, including any abnormal physical examinations, abnormal vital signs, abnormal ECG, and abnormal lab testing |
| Pharmacokinetic concentration | 32 weeks | To evaluate the Pharmacokinetic concentration of MG-K10 for each dose group. Population pharmacokinetic analysis is performed using a nonlinear mixed-effects model |
| Fractional exhaled nitric oxide (FeNO) | 32 weeks | At each evaluation time point, the changes of Fractional exhaled nitric oxide(FeNO) were compared with baseline in each group |
| thymus activation regulated chemokine (TARC) | 32 weeks | At each evaluation time point, the changes of thymus activation regulated chemokine (TARC) were compared with baseline in each group |
| serum immunoglobulin E (IgE) | 32 weeks | At each evaluation time point, the changes of serum immunoglobulin E (IgE)were compared with baseline in each group |
| Anti-drug antibodies (ADAs) and neutralizing antibodies (Nabs) | 32 weeks | Incidence of anti-drug antibodies (ADAs) and neutralizing antibodies (Nabs) (if applicable) |
| Morning/evening asthma symptom score | 24 and 32 week | Patients will record total symptom scores in morning(a 0-4 scale, with 0=no symptoms, 4=inability to fall asleep at night due to symptoms) and evening (a 0-4 scale, with 0=no symptoms, 4=severe symptoms, unable to work or perform daily activities) |
