Real-world comparative data on alternatives to omalizumab for antihistamine-refractory chronic spontaneous urticaria (CSU) are limited, particularly in resource-constrained Asia-Pacific settings.
Alexithymia is among psychological factors reported to interfere with asthma management. Severe allergic asthma (SAA) is characterized by uncontrolled asthma despite maximal standard pharmacological treatment which can benefit from an add-on treatment with Omalizumab, an anti-IgE monoclonal antibody.
Omalizumab is a safe and effective treatment for antihistamine-refractory chronic spontaneous urticaria (CSU) but is insufficient in one-third of patients. For serious cases in which omalizumab is ineffective, cyclosporine or methotrexate may be preferred. Most drug trials in CSU have focused on omalizumab or cyclosporine monotherapy.
Omalizumab has > 15 years of real-world evidence of effectiveness in Caucasian patients. In August 2017, it was approved as an add-on therapy for the management of moderate-to-severe asthma in China.
