What is Tezspire?

Tezspire

Tezspire is a human monoclonal antibody immunoglobulin G2 (IgG2) generated in Chinese hamster ovary (CHO) cells using recombinant DNA technology. It is a thymic stromal lymphopoietin (TSLP) blocker. The molecular weight of tezepelumab-ekko is approximately 147 kDa.

Tezspire  (tezepelumab-ekko) injection is a single-dose vial or single-dose pre-filled syringe of sterile, preservative-free, clear to opalescent, colorless to light yellow solution for subcutaneous injection.

Each single-dose vial or pre-filled syringe contains 1.91 mL of tezepelumab-ekko, 2.8 mg of glacial acetic acid, 48 mg of L-proline, 0.19 mg of polysorbate 80, sodium hydroxide, and water for injection. The pH of the water is 5.2.

Tezspire  is a prescribed medicine that is used in conjunction with other asthma medications to treat severe asthma in patients who are 12 years old or older whose asthma isn’t controlled by their current asthma medication.

Mechanism of Action

Tezepelumab-ekko is a thymic stromal lymphopoietin (TSLP) blocker, a human monoclonal antibody IgG2 that binds to human TSLP and blocks its interaction with the heterodimeric TSLP receptor with a dissociation constant of 15.8 pM. TSLP is a cytokine produced mostly by epithelial cells that has a role in the asthma inflammatory cascade.

Inflammation of the airways is a key factor in the development of asthma. Airway inflammation is caused by a variety of cell types (mast cells, eosinophils, neutrophils, macrophages, lymphocytes, and ILC2 cells), as well as mediators (histamine, eicosanoids, leukotrienes, and cytokines). Blocking TSLP with tezepelumab-ekko lowers inflammatory biomarkers and cytokines like blood eosinophils, airway submucosal eosinophils, IgE, FeNO, IL-5, and IL-13; however, the mechanism of tezepelumab-ekko action in asthma has yet to be determined.

What other drugs can impact Tezspire?

Discuss with your doctor the medications you are taking such as prescription and over-the-counter supplements including vitamins, supplements, and herbal supplements. Do not alter or stop taking corticosteroid medications or other asthma medicine unless your doctor advises you to.
