简要总结
To assess the efficacy of CHF6001 3200 μg total daily dose compared to placebo as add-on to maintenance medium-to-high dose inhaled corticosteroid/long-acting β2-agonist (ICS/LABA) combination therapy in reducing the rate of asthma exacerbations over the 52-week period of treatment.

- •Diagnosis of asthma: A documented history of physician-diagnosed asthma for at least 1 year and with diagnosis before the age of 50 years
- •Stable asthma therapy: a stable maintenance treatment with fixed combination of medium to high dose of ICS plus LABA for at least 3 months prior to screening. Medium and high doses of ICS are defined according to Global Initiative for Asthma (GINA) 2022
- •Lung function: A prebronchodilator Forced expiratory volume in the first second (FEV1) ≤80% of the predicted normal value, after appropriate washout from bronchodilators, at the screening visit and at randomisation visit

- •Poor asthma control: Evidence of poorly controlled or uncontrolled asthma as based on Asthma Control Questionnaire (ACQ-7) score ≥1.5 at screening and at randomization
- •History of asthma exacerbations: A documented history of: - At least 1 asthma exacerbation leading to hospitalization within the last 12 months prior to screening; or - 2 or more asthma exacerbations within the last 12 months prior to screening, defined as a worsening of asthma symptoms that leads to any of the following: - an outpatient treatment with Systemic corticosteroids( SCS*); - an inpatient hospitalisation because of asthma; - an emergency room visit that resulted in the use of SCS*; * including oral or parenteral routes (a single depo-injectable dose of corticosteroid will be considered the equivalent to a 3-day course of SCS)
- •A cooperative attitude and ability: - to correctly use the inhalers; - to perform all trial-related procedures including technically acceptable spirometry; - to correctly use the electronic diary (e-Diary) and home spirometer;
排除标准
- •Run-in compliance: e-Diary completion compliance <75% at randomization
- •Cardiovascular diseases: subjects who have a clinically significant (CS) cardiovascular condition according to Investigator’s judgement, such as but not limited to: congestive heart failure (New York Heart Association (NYHA) class IV); unstable or acute ischaemic heart disease in the last year prior to screening; history of sustained and non-sustained cardiac arrhythmias diagnosed in the last 6 months prior to screening and not controlled with a rate control strategy; high degree impulse conduction blocks (>2nd degree atrioventricular block type 2); persistent, long standing or paroxysmal atrial fibrillation
- •ECG criteria: any abnormal and CS 12-lead ECG that in the Investigator's opinion would affect efficacy or safety evaluation or place the subjects at risk. Male subjects with a QTcF >450 msec and female subjects with a QTcF >470 msec at screening are not eligible (not applicable for subjects with permanent atrial fibrillation and for subjects with pacemaker); not applicable for subjects for subjects with permanent atrial fibrillation and for subjects with pacemaker)
- •Previous medical history, evidence of an uncontrolled intercurrent illness, or any clinically relevant abnormal findings in haematology, clinical chemistry, or urinalysis that in the opinion of the Investigator and/or medical monitor may compromise the safety of the subject in the study or interfere with evaluation of the IMP or reduce the subject’s ability to participate in the study. Subjects with well-controlled comorbid disease (i.e.,hypertension, hyperlipidaemia, gastroesophageal reflux disease) on a stable treatment regimen for at least 15 days prior to screening are eligible; Subjects with a diagnosis of depression, generalised anxiety disorder, suicidal ideation or behaviour that may, according to the Investigator’s judgement, place the subject at undue risk
- •Subjects with a diagnosis of depression, generalised anxiety disorder, suicidal ideation or behaviour that may, according to the Investigator’s judgement, place the subject at undue risk
- •Patients mentally or legally incapacitated or patients accommodated in an establishment as a result of an official or judicial order
- •Liver diseases: subjects with severe hepatitis, chronic active hepatitis, or evidence of uncontrolled chronic liver disease according to the Investigator’s opinion
- •Drugs with hepatoxicity potential: subjects receiving treatment with any drug known to have a well-defined potential for hepatotoxicity (i.e., isoniazide, nimesulide, ketoconazole) and strong inhibitors of cytochrome P450 (CYP)3A4/5 (i.e.,itraconazole) within the previous 3 months before the screening visit
- •Contra-indications to IMP: Subjects with a history of allergy or hypersensitivity to β2-agonists, corticosteroids, phosphodiesterase-4 inhibitors or any of the excipients contained in any of the formulations used in the trial or a medical condition that in the Investigator’s opinion would contra-indicate study participation
- •Alcohol/drug abuse: Subjects with a known or suspected history of alcohol and/or drug abuse within 12 months prior to screening
- •Surgery: Subjects with major surgery (i.e., aortic and major vascular surgery, cystectomy, pneumonectomy, liver transplantation, oesophagostomy, duodeno-pancreatic surgery, etc.) in the 3 months prior to screening visit or planned during the trial; low-risk procedures are allowed during the trial (i.e., endoscopic procedures, cataract surgery, superficial breast surgery, partial mastectomy without lymph node dissection, etc.)
- •History of “at risk” asthma: history of near fatal asthma or of a past hospitalisation for asthma in intensive care unit which, in the judgement of the Investigator, may place the subject at undue risk
- •Subjects treated with non-potassium sparing diuretics (unless administered as a fixed-dose combination with a potassium conserving drug or changed to potassium sparing agent before the screening), nonselective β-blocking drugs, quinidine, quinidine like anti-arrhythmic, or any medication with a QTc prolongation potential or a history of QTc prolongation
