This is a multi-centre, randomized, double-blind,placebo parallel-controlled phase III study to evaluate the efficacy and safety of CMAB007 (recombinant humanized anti-immunoglobulin E(IgE) monoclonal antibody for injection) to treat asthma patients who remain not adequately controlled despite Med/high ICS plus LABA in China. Following a screening period of up to 2 weeks and run-in period of 4 weeks, randomized patients will enter a 24-week treatment period with CMAB007 or placebo. Efficacy and safety will be assessed at 4-week intervals during the treatment period.

None of other asthma controller medications other than seretide or symbicort including systemic steroid, leukotriene modifiers, theophylline, histamine1 receptor blockers, anticholinergic drugs, traditional Chinese medicine and so on have been used 2 weeks prior to screening. 8. At screening, FEV1 < 80% of the predicted normal value. 9. At screening, laboratory tests results should meet all of the following: hemoglobin=80g/l;3*10^9/l=white blood cell=10*10^9/l;platelet=75*10^9/l;liver function(glutamic-pyruvic transaminase, glutamic-oxalacetic transaminase and total bilirubin)=2*upper limit of normal value;renal function=1.5*upper limit of normal value. 10. At screening, pregnant test is negative,or not lactating, for women of child-bearing potential. Effective methods of contraception will be maintained throughout the study and 6 months after the study. 11. Can understand and complete questionnaires correctly, complete PEF and patient diary correctly, and be followed up according to scheduled table. Exclusion Criteria: 1. History of critical asthma exacerbations,such as tracheal intubation or intensive care unit admission. 2. Currently smoker, or a former smoker with a smoking history > 10 pack-years(defined as the number of packs of 20 cigarettes smoked per day multiplied by number of years the patient smoked). 3. Have elevated serum IgE levels for other causes other than allergens, such as parasite infections, allergic bronchopulmonary aspergillosis, Churg-Strauss syndrome and so on. 4. Desensitization therapy or immunosuppressant agents such as cyclosporine, methotrexate and gold preparation during 3 months prior to screening. 5. Biological agents such as monoclonal antibody including investigational biological drugs during 6 months prior to screening. 6. Vaccinated live/attenuated virus or bacterial vaccines, or intravenous used immunoglobulin G, during 4 weeks prior to screening. 7. History of bronchial thermoplasty for asthma during 12 months prior to screening. 8. Use of any anti-IgE monoclonal antibody including Xolair for asthma during 12 months prior to screening. 9. Respiratory infections(such as pneumonia,upper respiratory tract infection,etc)or large surgeries during 4 weeks prior to screening. 10. Combined with other pulmonary diseases, such as chronic obstructive pulmonary disease, bronchiectasis, pulmonary interstitial fibrosis, etc. 11. History of malignancies other than squamous cell carcinoma or basal cell carcinoma of the skin and carcinoma in situs of cervix with complete excision and no evidence of recurrences. 12. Acquired immune deficiency syndrome or human immunodeficiency virus infection patients. 13. History of malignant or proliferative diseases of the lymphatic system such as lymphoma, or there are symptoms and signs indicating lymphatic proliferative diseases, or splenomegaly (=2cm under the ribs). 14. With uncontrolled hypertension(systolic pressure =160 or diastolic pressure =100 in millimeters of mercury) at screening. 15. With severe, progressive or uncontrolled hepatic, renal, gastrointestinal, cardio-cerebral vascular, hematopoietic,genitourinary, endocrine, nervous and immunological medical conditions, or other conditions that investigators think the patient not suitable for this study. 16. Have a history of drug or alcohol abuse or poor compliance of drugs. 17. With known hypersensitivity to human immunoglobulin, anti-IgE monoclonal antibody for injection or components. 18. Have attended other clinical trials of investigational drugs, or within 30 days or 5 half-lives of enrollment, whichever is longer. |
