Omalizumab therapy improved asthma control in patients with moderate to severe asthma over two years. This real-world study shows sustained benefits for new and established omalizumab users.
Area of Science:
- Pulmonology
- Immunology
- Clinical Practice Research
Background:
- Asthma guidelines highlight the need for adequate asthma control.
- Many patients with moderate to severe asthma do not achieve sufficient control.
Purpose of the Study:
- To evaluate the long-term effects of omalizumab on asthma control.
- This analysis focused on real-world clinical practice settings.
Main Methods:
- An observational cohort study (EXCELS) included omalizumab-treated and non-omalizumab-treated patients (≥12 years) with moderate to severe asthma.
- Asthma control was assessed using the Asthma Control Test (ACT) every six months over two years.
Main Results:
- Over 50% of new omalizumab users achieved clinically meaningful improvement in ACT by six months, with sustained benefits at 24 months.
- Established omalizumab users maintained their asthma control throughout the two-year follow-up period.
- Similar improvements were noted in patients with moderate and severe asthma.
Conclusions:
- Initiating omalizumab therapy leads to clinically relevant and sustained improvements in asthma control over two years.
- Established omalizumab users consistently maintained asthma control during the study period.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Asthma: Pathogenesis and Management
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
