TEZSPIRE consistently demonstrated statistically significant reductions in exacerbations across two pivotal trials (PATHWAY, 71%; NAVIGATOR, 56%; P<0.001).1-3*

In the NAVIGATOR trial, a 79% reduction in exacerbations requiring ED visits,† urgent care visits, or hospitalizations was observed.1,3,4‡
Secondary Endpoint. Results are descriptive only.

In NAVIGATOR, TEZSPIRE also demonstrated a 230 mL improvement in FEV1 from baseline1,3§ with 70% of the lung function improvement achieved at 2 weeks and sustained through 52 weeks.1,3,5||

*PATHWAY AAER: TEZSPIRE + SOC 0.20 (n=137) vs placebo + SOC 0.72 (n=138); RR: 0.29 (95% Cl: 0.16-0.51); NAVIGATOR AAER: TEZSPIRE + SOC 0.93 (n=528) vs placebo + SOC 2.10 (n=531); RR: 0.44 (95% Cl: 0.37-0.53).1

†An emergency room visit was defined as evaluation and treatment for <24 hours in an ER or urgent care center that required systemic corticosteroids.6

‡Results are from NAVIGATOR. TEZSPIRE + SOC AAER 0.06 (n=528) vs placebo + SOC 0.28 (n=531); RR: 0.21 (95% CI: 0.12-0.37).1

§Least-squares mean change from baseline in pre-BD FEV1: TEZSPIRE + SOC 0.23 L (n=527) vs placebo + SOC 0.10 L (n=531); (Difference, 0.13 L; 95% CI, 0.08 to 0.18; P<0.001).1,3

||At 2 weeks there was a 160 mL least-squares mean change from baseline in the pre-BD FEV1. Statistical significance for FEV1 improvement was established at end of treatment. Week 2 results were descriptive only.5

Important Safety Information

Collapse

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)
