What is Tezepelumab, and how does it work?

Question

Hello doctor,

I have been struggling to control my asthma despite using my regular inhalers and medications. My pulmonologist recently mentioned Tezspire as a potential option, but I am not familiar with it.

Could you please explain how Tezspire works and how it compares to other biologics like Dupixent or Xolair? Additionally, I would like to know how it is administered is it an inhaler, an injection, or something else? I would appreciate any insights on whether Tezspire has been effective for people with severe asthma.

Kindly advise.

Hello,

Welcome to iCliniq.com.

I understand your concern.

Tezspire (Tezepelumab) is a prescription medication used for the treatment of severe asthma. It is a monoclonal antibody that targets the thymic stromal lymphopoietin (TSLP) pathway, which plays a crucial role in triggering and sustaining allergic inflammation in asthma.

Tezspire works by blocking the TSLP pathway, reducing inflammation, and preventing asthma exacerbations. By targeting this pathway, it offers a broader treatment approach for severe asthma.

Tezspire differs from other biologics, such as Dupixent (Dupilumab) and Xolair (Omalizumab). While Dupixent targets the IL-4/IL-13 pathway and Xolair focuses on IgE, Tezspire blocks the TSLP pathway. This unique mechanism may make it a better option for certain patients.

Tezspire is administered as a subcutaneous injection every four weeks. It is not an inhaler but a shot given under the skin.

Clinical studies have shown that Tezspire significantly reduces asthma exacerbations and improves lung function in patients with severe asthma. It has also been found to be effective in patients who have not responded well to other biologic treatments.

I hope you are satisfied with my answer. For further queries, you can consult me at iCliniq.

Thank you.

Take care.
