Combination Therapy of Omalizumab and Allergen Immunotherapy for Moderate to Severe Asthma
Sponsor: Qianfoshan Hospital
Summary
The combined treatment of anti-IgE monoclonal antibody and standardized allergen immunotherapy has good efficacy and safety in allergic diseases. However, the efficacy and safety of the combined treatment for allergic asthma in the Chinese population have not been fully elucidated yet.This study is a prospective observational study designed to evaluate the efficacy and safety of omalizumab combined with allergen immunotherapy (AIT) in patients with moderate to severe asthma in the Chinese population.

Allergen-specific immunotherapy(AIT)
Allergen-Specific Immunotherapy(AIT) Protocol: using the house dust mite allergen preparation (Alutard, ALK Company, Denmark). The treatment course was divided into the initial treatment stage and the maintenance treatment stage. The initial treatment stage, also known as the dose accumulation stage, involved injecting the vaccine once a week and usually lasted for 15 weeks. For highly sensitive patients, treatment was carried out according to the dose guidelines for "high sensitivity". The maximum dose in the initial treatment stage was the maintenance dose. After reaching the maintenance dose, the first maintenance injection was given 2 weeks later, the second maintenance injection was given 4 weeks later, and thereafter, a vaccine injection was carried out every 4 - 8 weeks.
omalizumab
Omalizumab Treatment Protocol: The dosage and administration frequency (once every 2 weeks or once every 4 weeks) of omalizumab were determined based on the patients' pretreatment serum total IgE (kU/L), age, and body weight (kg). Each dosage ranged from 15 to 600 mg and was administered subcutaneously. If the dosage was ≤ 150 mg, it was injected subcutaneously at 1 site; otherwise, it was injected subcutaneously at 1 to 4 sites respectively. After the first 3 injections, patients were observed in the hospital for at least 2 hours, and after the 4th and subsequent injections, they were observed for at least 30 minutes. During the treatment period, the background medications for asthma control were adjusted according to the patient's condition.
