How effective is Tezpire in managing asthma?

Question

Hello doctor,

My 48-year-old brother has been struggling with asthma that’s not triggered by allergies. His pulmonologist mentioned Tezspire as a newer injectable treatment that might reduce flare-ups. He’s been on multiple inhalers and oral steroids, but his symptoms keep coming back. We’re wondering how this medicine works compared to others like Xolair or Dupixent. Does it start working quickly or take a few months? Is it safe for long-term use? We’re also wondering about insurance approval and cost, since it seems like a newer drug. He’s hopeful, but we’d love to hear how effective Tezspire is for non-allergic asthma.

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Tezspire (Tezepelumab) is one of the latest and most promising treatments for asthma, and because it is particularly non-allergic or type 2" asthma", your sibling could be a great candidate, especially if other treatments are not helpful.

How Tezspire works: In contrast to older biologics such as Xolair (Omalizumab) and Dupilumab, which are intended for specific pathways (such as IgE or IL-4/IL-13), Tezspire blocks thymic stromal lymphopoietin (TSLP). This is the master trigger at the top of the inflammatory cascade.
Conclusion: Tezspire works better than other biologics in non-allergic asthma (not driven by IgE or eosinophils) and steroid-dependent asthma.

How quickly does it work?

Some patients notice fewer symptoms in the first 46 weeks. However, the biggest advantage is usually shown after 36 months. Monthly injections (every 4 weeks) at home or the clinic.
Safety and long-term use: In general, it can withstand placebo-like side effects in experiments. No black box warnings (as opposed to Xolair with anaphylaxis).

Many insurance plans are covered, especially with prior approval. The cost is high.

I hope this information helps you.

Thank you.
