MOST PATIENTS HAVE MULTIPLE TRIGGERS

The number of triggers has been shown to be a strong predictor of exacerbations and hospitalizations7*
elevant-biomarkers

MOST PATIENTS HAVE ELEVATED BIOMARKERS

~2/3 of severe asthma patients experienced 2 or more elevated biomarkers, such as blood EOS8†

*Data from CHRONICLE, an observational study of adults with severe asthma. Analysis examined patient-reported triggers (n=1434) from a 17-category survey and associations with multiple measures of disease burden.7

Data from the International Severe Asthma Registry (ISAR), a global initiative to gather anonymous, longitudinal real-world data. Patients with severe asthma enrolled in ISAR are ≥18 years of age and either have uncontrolled asthma at Global initiative for Asthma (GINA) step 4 treatment or are receiving GINA step 5 treatment; all were on high-dose inhaled corticosteroids. Data were analyzed from 1175 patients from 10 countries in North America, Europe, and Asia. In this study, 59% of patients were positive for 2 or 3 of the biomarkers assessed (IgE, FeNO, and blood EOS).8

EOS=eosinophils; FeNO=fractional exhaled nitric oxide; IgE=immunoglobulin E; IL=interleukin; TSLP=thymic stromal lymphopoietin.

CONTRAINDICATIONS

Known hypersensitivity to tezepelumab-ekko or excipients.

WARNINGS AND PRECAUTIONS

Hypersensitivity Reactions

Hypersensitivity reactions were observed in the clinical trials (eg, rash and allergic conjunctivitis) following the administration of TEZSPIRE. Postmarketing cases of anaphylaxis have been reported. These reactions can occur within hours of administration, but in some instances have a delayed onset (i.e., days). In the event of a hypersensitivity reaction, consider the benefits and risks for the individual patient to determine whether to continue or discontinue treatment with TEZSPIRE.

Acute Asthma Symptoms or Deteriorating Disease

TEZSPIRE should not be used to treat acute asthma symptoms, acute exacerbations, acute bronchospasm, or status asthmaticus.

Abrupt Reduction of Corticosteroid Dosage

Do not discontinue systemic or inhaled corticosteroids abruptly upon initiation of therapy with TEZSPIRE. Reductions in corticosteroid dose, if appropriate, should be gradual and performed under the direct supervision of a physician. Reduction in corticosteroid dose may be associated with systemic withdrawal symptoms and/or unmask conditions previously suppressed by systemic corticosteroid therapy.

Parasitic (Helminth) Infection

It is unknown if TEZSPIRE will influence a patient’s response against helminth infections. Treat patients with pre-existing helminth infections before initiating therapy with TEZSPIRE. If patients become infected while receiving TEZSPIRE and do not respond to anti-helminth treatment, discontinue TEZSPIRE until infection resolves.

Live Attenuated Vaccines

The concomitant use of TEZSPIRE and live attenuated vaccines has not been evaluated. The use of live attenuated vaccines should be avoided in patients receiving TEZSPIRE.

ADVERSE REACTIONS

The most common adverse reactions (incidence ≥ 3%) are:

  • Asthma: pharyngitis, arthralgia, and back pain.
  • Chronic rhinosinusitis with nasal polyps: nasopharyngitis, upper respiratory tract infection, epistaxis, pharyngitis, back pain, influenza, injection site reaction and arthralgia

USE IN SPECIFIC POPULATIONS

There are no available data on TEZSPIRE use in pregnant women to evaluate for any drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. Placental transfer of monoclonal antibodies such as tezepelumab-ekko is greater during the third trimester of pregnancy; therefore, potential effects on a fetus are likely to be greater during the third trimester of pregnancy.

INDICATION

TEZSPIRE is indicated for:

  • the add-on maintenance treatment of adult and pediatric patients aged 12 years and older with severe asthma. TEZSPIRE is not indicated for the relief of acute bronchospasm or status asthmaticus
  • the add-on maintenance treatment of adult and pediatric patients aged 12 years and older with inadequately controlled chronic rhinosinusitis with nasal polyps (CRSwNP)
