Conditions
Brief summary
This study will assess the effcacy and safety of 610 as an adjunctive therapy in adult subjects with severe eosinophilic asthma.
Detailed description
This is a multicenter, randomized, double-blind, placebo-controlled study to evaluate the effcacy and safety of 610 in adults with severe eosinophilic asthma. Subjects divided into 3 groups: A group,B group and placebo group. The study is divided into screening period of 4 weeks, treatment period of 16 weeks, prolonged treatment period of 36 weeks and follow-up period of 8 weeks.

Diagnosed with asthma for ≥12 months that meet GINA. * 4\. History of physician-diagnosed asthma requiring treatment with ICS and at least one other control medication for at least 6 months prior to screening. * 5\. Documented history of ≥ 1 moderate exacerbations within 12 months prior to screening. * 6\.

Exclusion criteria
* 1\. Presence of a known pre-existing, clinically important lung condition other than Asthma. * 2\. Severe asthma exacerbation within 4 weeks prior to randomization. * 3\. Subjects with any eosinophilic diseases other than asthma. * 4\. Known, pre-existing severe or clinically significant cardiovascular disease. * 5\. known, pre-existing other concurrent clinically significant medical conditions that are uncontrolled with standard treatment. * 6\.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline in pre-bronchodilator forced expiratory volume in one second (FEV1) at week 52 | Baseline (Day 1) and at week 52 | FEV1 is defined as the volume of air expelled from the lungs in 1 second. Pre-bronchodilator FEV1 measurements were taken by spirometry. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Changes from baseline in pre-bronchodilator forced expiratory volume in one second (FEV1) at week 16 | Baseline (Day 1) and at week 16 | FEV1 is defined as the volume of air expelled from the lungs in 1 second. Pre-bronchodilator FEV1 measurements were taken by spirometry. |
| Percentage change from baseline in pre-bronchodilator FEV1 at weeks 4, 8,12,16, 20, 28, 36, 44, 52 | Baseline (Day 1) and at week 4, 8,12,16, 20, 28, 36, 44, 52 | Percentage of FEV1 will be measured using spirometry. |
| Number of asthma exacerbation through study week 52 | From baseline (Day 1) to week 52 | Annualized rate of severe exacerbation events during the 52-week placebo-controlled treatment period |
| Number of asthma exacerbations requiring hospitalization or emergency room visits | From baseline (Day 1) to week 52 | Asthma exacerbations that are associated with a hospitalization or an emergency room visit. |
| Change from baseline in Asthma Control Questionnaire (ACQ) score. | From baseline (Day 1) to week 52 | The ACQ contains five symptom questions (nocturnal awakening on waking in the morning, activity limitation, and shortness of breath, wheeze), one bronchodilator question and pre-bronchodilator FEV1 level. Questions are rated from 0 (totally controlled) to 6 (severely uncontrolled). Mean ACQ score is the average of the responses. Higher score indicates more limitations. |
| Change from baseline in ST. GEORGE'S Respiratory Questionnaire(SGRQ) | From baseline (Day 1) to week 52 | The SGRQ is designed to measure health impairment in patients with asthma and COPD. It contains two parts: Part 1 (Questions 1 to 8) covers the patients' recollection of their symptoms over a preceding 4 weeks; Part 2, 42 items, relates to the daily activity and psychosocial impacts of the individual's respiratory condition. Total score is presented as a percentage of overall impairment, in which 100 represents the worst possible health status, while 0 indicates the best. |
| Assessment of adverse events (AEs) | Up to week 60 | Number of participants with adverse events (AEs) |
