Safety and Efficacy Study of Omalizumab to Treat Allergic Asthma

Phase 2
Completed
Conditions
Allergic Asthma
Interventions
Drug: placebo
Registration Number
NCT01976208
Lead Sponsor
Shanghai Zhangjiang Biotechnology Limited Company
Brief Summary

The primary purpose is to evaluate the safety and efficacy of recombinant humanized anti-IgE monoclonal antibody injection in patients with allergic asthma.

Detailed Description

Omalizumab will be given as add-on treatment to budesonide inhaled powder in patients with moderate or severe allergic asthma(IgE\>=60IU/ml), who demonstrate inadequate asthma symptom control. Response to Omalizumab will be assessed by the overall improvement in control of asthma.

Omalizumab is a recombinant humanized monoclonal antibody that selectively binds to human immunoglobulin E(IgE). The antibody has a molecular weight of approximately 150 kilodaltons and produced by Chinese Hamster Ovary cell.

Omalizumab inhibits the binding of IgE to the high-affinity IgE receptor on the surface of mast cells and basophils. Reduction in surface-bound IgE on cells limits the degree of release of mediators of the allergic response.

placeboplaceboDuring the 4\~6-week Run-in phase, the dosage of budesonide inhaled powder(BUD) was prescribed and optimized to maintain asthma control according to Global Initiative for Asthma(GINA, 2008) guidelines. During the treatment phase, patients continued to receive placebo and optimized BUD for 28 weeks, administered by subcutaneous injection every 2 weeks or 4 weeks.

During the following treatment phase, patients continued to receive optimized BUD and Omalizumab for 28 weeks, administered by subcutaneous injection every 2 weeks or 4 weeks. The dosage of Omalizumab received was based on body weight and serum IgE.
