Background
U.S. Food and Drug Administration (FDA)-Approved Indications
-
Tezspire is indicated for add-on maintenance treatment of adult and pediatric patients aged 12 years and older with severe asthma.
Limitations of use:
Not for relief of acute bronchospasm or status asthmaticus.
Tezepelumab-ekko is available as Tezspire (Amgen Inc.). Tezepelumab-ekko is a thymic stromal lymphopoietin (TSLP) blocker, human monoclonal antibody (IgG2λ). TSLP, a molecule involved in airway inflammation, is a cytokine mainly derived from epithelial cells and occupies an upstream position in the asthma inflammatory cascade. Airway inflammation is an important component in the pathogenesis of asthma. Multiple cell types (e.g., mast cells, eosinophils, neutrophils, macrophages, lymphocytes, ILC2 cells) and mediators (e.g., histamine, eicosanoids, leukotrienes, cytokines) are involved in airway inflammation. Blocking TSLP with tezepelumab-ekko reduces biomarkers and cytokines associated with inflammation including blood eosinophils, airway submucosal eosinophils, IgE, FeNO, IL-5, and IL-13; however, the mechanism of tezepelumab-ekko action in asthma has not been definitively established (Amgen, 2021).
Tezspire carries labeled warnings and precautions for hypersensitivity reactions (e.g., rash and allergic conjunctivitis) and risk for parasitic (helminth) infection. Hypersensitivity reactions can occur within hours of administration, but in some instances have a delayed onset (i.e., days). TSLP may be involved in the immunological response to some helminth infections; however, patients with known helminth infections were excluded from participation in clinical trials. Thus, it is unknown if Tezspire will influence a patient’s response against helminth infections.
Per the label, Tezspire should not be used to treat acute asthma symptoms or acute exacerbations. Tezspire is not to be used to treat acute bronchospasm or status asthmaticus. Patients should seek medical advice if their asthma remains uncontrolled or worsens after initiation of treatment with Tezspire. It is recommended that patients 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.
The concomitant use of Tezspire and live attenuated vaccines has not been evaluated. Therefore, the use of live attenuated vaccines should be avoided in patients receiving Tezspire.
The most common adverse reactions (incidence of 3% or more) include pharyngitis, arthralgia, and back pain.
Asthma
Asthma is chronic, heterogenous condition that is usually associated with airway inflammation and bronchial hyperresponsiveness which results in narrowing of the airways, leading to less airflow to the lungs. Airway swelling or inflammation can be triggered by several factors, including allergens or irritant exposure and viral infections. Respiratory symptoms, "asthma attack" exacerbation, may include wheeze, chest tightness, shortness of breath, and/or cough, which can vary in frequency and intensity over time. Airflow limitation may later become persistent and severe (GINA, 2021; FDA, 2021).
According to the Global Initiative for Asthma (GINA) (2021), severe asthma is defined as asthma that is uncontrolled despite high dose inhaled corticosteroid (ICS)-long-acting beta2 agonist (LABA), or that requires high dose ICS-LABA to remain controlled. "Severe asthma attacks can be intense, last for long periods of time, and impact daily activities. Severe asthma symptoms usually do not get better with use of short-term treatments. Approximately 5-10 percent of Americans with asthma have severe asthma" (FDA, 2021).
On December 20, 2021, the FDA announced the approval of the first asthma treatment targeting thymic stromal lymphopoietin (TSLP). Tezspire (tezepelumab-ekko), a TSLP blocker, human monoclonal antibody (IgG2λ), was approved as an add-on maintenance treatment used to improve severe asthma symptoms when used with a patient’s current asthma medicine. Tezspire is approved for adults and children aged 12 years and older with severe asthma not controlled by their current asthma medicine. Tezspire is also the first treatment for severe asthma that is not limited to a specific type of severe asthma. Tezspire is administered once every four weeks as a subcutaneous injection by a health care professional.
FDA approval as based on the safety and efficacy in two randomized, double-blind, parallel group, placebo-controlled clinical trials (PATHFINDER, NCT02054130; NAVIGATOR, NCT03347279) in which patients receiving Tezspire had significant reductions in the annualized rate of asthma attacks compared to placebo. Additionally, there were fewer asthma attacks requiring emergency room visits and/or hospitalization among patients treated with Tezspire compared to placebo. The benefits of Tezspire seen in patients weren’t limited by specific severe asthma type (FDA, 2021).
Corren et al (2021) state that in the phase 2b PATHWAY study, tezepelumab reduced exacerbations by up to 71% and improved lung function, asthma control, and health-related quality of life vs placebo. Adults with severe, uncontrolled asthma were randomized to subcutaneous tezepelumab (70 mg every 4 weeks, 210 mg every 4 weeks, or 280 mg every 2 weeks) or placebo for 52 weeks. Inclusion criteria required documented physician-diagnosed asthma. Patients must have received a physician-prescribed asthma controller regimen with medium- or high-dose inhaled corticosteroids (ICS) plus long acting β2 agonist (LABA). If on asthma controller medications in addition to ICS plus LABA, the dose of the other asthma controller medications (leukotriene receptor inhibitors, theophylline, secondary ICS, long-acting anti-muscarinics (LAMA), cromones, or maintenance oral prednisone or equivalent up to a maximum of 10 mg daily or 20 mg every other day for the maintenance treatment of asthma) must be stable. Patients must have a documented history of at least 2 asthma exacerbation events or at least 1 severe asthma exacerbation resulting in hospitalization within the 12 months prior to first study visit. Patient-reported outcomes (PROs) were assessed using the asthma control questionnaire-6 (ACQ-6) and the asthma quality of life questionnaire (standardized) for patients aged 12 years or older (AQLQ[S]+12). The proportions of responders (defined by improvements of ≥0.5 in ACQ-6 or AQLQ(S)+12 scores) and patients whose asthma was well-controlled, partially-controlled, or uncontrolled in the tezepelumab and placebo groups were identified. The Asthma Daily Diary questionnaire was used to assess changes in overall symptom severity. Overall, 550 patients were randomized. The authors found that up to 82% and 77% of tezepelumab-treated patients were ACQ-6 and AQLQ(S)+12 responders, respectively, compared with 70% and 64% of placebo-treated patients, respectively. The proportions of patients with well-controlled or partially-controlled asthma were higher in the tezepelumab-treated group than in the placebo group. In addition, tezepelumab improved the overall symptom severity. The authors concluded that tezepelumab treatment improved PROs vs placebo, as indicated by the higher proportion of ACQ-6 and AQLQ(S)+12 responders and improvements in symptom severity in the tezepelumab dose groups. These data further support the benefits of tezepelumab in patients with severe, uncontrolled asthma.
Menzies-Gow et al (2021) conducted a phase 3, multicenter, randomized, double-blind, placebo-controlled trial (NAVIGATOR). Patients (12 to 80 years of age; n=1061) were randomly assigned to receive tezepelumab (210 mg) or placebo subcutaneously every 4 weeks for 52 weeks. Inclusion criteria required patients, aged 12 to 80 years, to have documented physician-diagnosed asthma for at least 12 months, have received a physician-prescribed asthma controller medication with medium or high dose ICS for at least 12 months, documented treatment with a total daily dose of either medium or high dose ICS (≥ 500 µg fluticasone propionate dry powder formulation equivalent total daily dose) for at least 3 months, have at least one additional maintenance asthma controller medication according to standard practice of care for at least 3 months, morning pre-BD FEV1 <80% predicted normal (<90% for subjects 12-17 years), evidence of asthma as documented by either: documented historical reversibility of FEV1 ≥12% and ≥200 mL in the previous 12 months or post-BD (albuterol/salbutamol) reversibility of FEV1 ≥12% and ≥200 mL during screening, documented history of at least 2 asthma exacerbation events within 12 months, and have an ACQ-6 score ≥1.5 at screening and on day of randomization. The primary end point was the annualized rate of asthma exacerbations over a period of 52 weeks. This end point was also assessed in patients with baseline blood eosinophil counts of less than 300 cells per microliter. Secondary end points included the forced expiratory volume in 1 second (FEV1) and scores on the Asthma Control Questionnaire-6 (ACQ-6; range, 0 [no impairment] to 6 [maximum impairment]), Asthma Quality of Life Questionnaire (AQLQ; range, 1 [maximum impairment] to 7 [no impairment]), and Asthma Symptom Diary (ASD; range, 0 [no symptoms] to 4 [worst possible symptoms]). Overall, 1061 patients underwent randomization (529 were assigned to receive tezepelumab and 532 to receive placebo). The annualized rate of asthma exacerbations was 0.93 (95% confidence interval [CI], 0.80 to 1.07) with tezepelumab and 2.10 (95% CI, 1.84 to 2.39) with placebo (rate ratio, 0.44; 95% CI, 0.37 to 0.53; p<0.001). In patients with a blood eosinophil count of less than 300 cells per microliter, the annualized rate was 1.02 (95% CI, 0.84 to 1.23) with tezepelumab and 1.73 (95% CI, 1.46 to 2.05) with placebo (p<0.001). At week 52, improvements were greater with tezepelumab than with placebo with respect to the prebronchodilator FEV1 (p<0.001) and scores on the ACQ-6 (p<0.001), AQLQ (p<0.001), and ASD (p = 0.002). The frequencies and types of adverse events did not differ meaningfully between the two groups. The authors concluded that patients with severe, uncontrolled asthma who received tezepelumab had fewer exacerbations and better lung function, asthma control, and health-related quality of life than those who received placebo.
