入选标准
- •1. For patients considered to be minors according to national legislation in each country, the written consent of the parent or legal guardian must be obtained, as well as the assent of the minor according to his or her capacity to understand the information provided. Patients within the specified age range who are not legally considered to be minors according to national legislation must consent in their own right. Patients enrolled as minors who attain legal adulthood during the course of the study must consent in their own right at that time
- •2. Ability and willingness to comply with the study procedures
- •3. Age =12 to =75 years at the time of informed consent
- •4. Severe asthma (as defined by GINA step 5 classification of asthma severity) after a detailed systematic assessment (the BTS UK Difficult Asthma Network assessment model [Heaney et al 2010] or equivalent) and follow-up by an asthma specialist for at least six months
- •5. History of asthma treatment with high doses of ICS (=1500 µg beclomethasone dipropionate daily, or equivalent) and LABAs, with or without an additional controller, for at least six months before Screening
- •6. Chronic treatment with maintenance OCS for at least six months before the time of informed consent with treatment during the last 28 days being within the following ranges:
- •±2.5 mg/day daily dose equivalent for patients within the range of 10 to 20 mg/day (range 5 to 20 mg for adolescents)
- •±5 mg/day daily dose equivalent for patients within the range of
- •21 to 40 mg/day
- •7. Baseline OCS dose as follows:
- •Adults: 10 to 40 mg/day
- •Adolescents: 5 to 40 mg/day daily dose equivalent
- •8. Compliance with OCS therapy will be based on prior detectable levels of serum prednisolone, cortisol suppression, or observation of Cushingoid appearance consistent with regular systemic steroid use
- •9. Prior assessment within the six months before the time of informed consent is obtained according to the assessment model of the BTS UK Difficult Asthma Network or equivalent to ensure a diagnosis of refractory asthma (Heaney et al 2010) with OCS dependence on minimal effective or maximum tolerated dose, defined as follows:
- •Patient has ‘uncontrolled’ asthma and has detectable serum prednisolone or undetectable cortisol. ‘Uncontrolled’ asthma is defined by any of the following:
- •ACQ-7 >1.25 or
- •Persistent blood eosinophil count (>0.4 x 109/mL) or
- •Persistent sputum eosinophilia (>3%) or
- •Recurrent exacerbations requiring a boost in steroid dose
- •Note: Patients that do not meet the ‘uncontrolled’ asthma criteria listed previously will be defined as ‘controlled’
- •Patient has ‘controlled’ asthma and has documented evidence of previous failed OCS down-titration
- •Note: For patients who are controlled with no documented evidence of failed OCS down-titration, OCS dose optimisation will take place within the context of the BTS (or equivalent) standardised protocols before considering the patient for Screening (considered standard of care for optimisation daily steroid use). During this process, the OCS dose will be reduced at weekly intervals in predefined steps until either of the following criteria for OCS down-titration failure is met:
- •Forced expiratory volume in 1 second (FEV1) <80% of the patient’s personal best value while on the current OCS dose, or
- •Increase in 24-hour asthma symptoms, night time awakenings, or
- •10. Chest x-ray or computed tomography (CT) scan obtained within the
- •12 months b
排除标准
- •1. Baseline FEV1 =39% of predicted
- •2. Asthma exacerbation (as described in Section 4.2.6.5) within 28 days before the time of informed consent or during Screening
- •3. Major episode of infection requiring any of the following:
- •Admission to hospital for =24 hours within the 28 days before the time of informed consent or during Screening
- •Treatment with intravenous antibiotics within the 28 days before the time of informed consent or during Screening
- •Treatment with oral antibiotics within the 14 days before the time of informed consent or during Screening
- •4. Active parasitic infection or Listeria monocytogenes infection within the 6 months before the time of informed consent
- •5. For adults: Active tuberculosis (TB) requiring treatment within the 12 months before the time of informed consent (patients are also required to have no recurrence of symptoms in the 12 months following completion of TB treatment), or For adolescents: History of active TB requiring treatment
- •6. Known history of severe clinically significant immunodeficiency, including, but not limited to, human immunodeficiency virus infection and/or currently receiving or have historically received intravenous Ig for treatment for immunodeficiency
- •Note: Immunodeficiency encompasses a wide spectrum of human conditions and/or diseases. A relative IgG deficiency that is thought, but not proven, to be a feature of severe asthma would not be exclusionary for the study. All cases of doubt should be discussed with the medical monitor
- •7. Evidence of acute or chronic hepatitis or known liver cirrhosis
- •8. Aspartate aminotransferase (AST) and/or alanine aminotransferase (ALT) and/or total bilirubin elevation =2.0 x the upper limit of normal (ULN)
- •9. Diagnosis or history of malignancy, or current investigation for possible malignancy
- •10. Other clinically significant medical disease that is uncontrolled despite treatment or that is likely, in the opinion of the investigator, to require a change in therapy or affect the ability to participate in the study
- •11. History of alcohol, drug, or chemical abuse that would impair or risk the patient’s full participation in the study, in the opinion of the investigator
- •12. Current smoker or former smoker with a smoking history of >15 pack-years. A current smoker is defined as someone who has smoked one or more cigarettes per day (or marijuana or pipe or cigar) for =30 days within the 24 months before the time of informed consent and for whom cotinine testing is positive.
- •A former smoker is defined as someone who has smoked one or more cigarettes per day (or marijuana or pipe or cigar) for =30 days in his or her lifetime (as long as the 30-day total did not include the 24 months before the time of informed consent) and for whom cotinine testing is negative.
- •A pack-year is defined as the average number of packs per day times the number of years of smoking.
- •13. Current use of an immunomodulatory/immunosuppressive therapy or past use within three months or five drug half-lives (whichever is longer) before the time of informed consent
- •14. Use of a biologic therapy (including omalizumab) at any time during the 4 months before the time of informed consent
- •15. History of anaphylaxis with omalizumab treatment or history of anaphylaxis to any therapeutic biological agent
- •16. Use of zileuton or roflumilast at any time during the two months before the time of informed consent
- •17. Initiation of or change in allergen immunotherapy within three
