Szczegółowy opis

Jest to wieloośrodkowe, jednoramienne, otwarte badanie fazy 4 po wydaniu pozwolenia, mające na celu ocenę skuteczności tezepelumabu w Stanach Zjednoczonych (USA) wśród rzeczywistej populacji dorosłych i nastolatków z astmą wymagających średnich dawek na wziewne kortykosteroidy (ICS) w dużych dawkach, z dodatkowymi kontrolerami przez co najmniej 12 miesięcy z udokumentowaną historią co najmniej 2 zaostrzeń astmy w ciągu roku. Całkowity czas trwania badania dla każdego uczestnika wyniesie około 56 tygodni. Zarejestrowanych zostanie około 400 uczestników. Uczestnicy otrzymają tezepelumab we wstrzyknięciu podskórnym w miejscu badania przez 48-tygodniowy okres leczenia. Badanie obejmuje również okres obserwacji po podaniu dawki od 48 do 52 tygodni.

Annualized Asthma Exacerbation Rate (AAER)
Ramy czasowe: Baseline period (Week -52 to Week 0), Study period (Week 0 to Week 52)

Asthma exacerbations were defined by worsening of asthma symptoms that leads to temporary bolus/burst of systemic corticosteroids for at least 3 consecutive days, or an emergency department (ED) or urgent care visit due to asthma that required systemic corticosteroid (SCS), and/or inpatient hospitalization (≥24 hours) due to asthma. The AAER was based on exacerbations reported by the investigator over 52 weeks.

The exacerbation rate was compared between the 12-month period before [baseline period (BP)] and the 12-month period after initiation of tezepelumab [up to study Week 52 (Visit 15) = study period (SP)].

ACQ assesses symptoms and rescue bronchodilator use. Questions are weighted equally and scored from 0 (totally controlled) to 6 (severely uncontrolled), with higher scores indicating worse asthma control. The mean (average) ACQ-6 score is the mean of the responses.

Ramy czasowe: Baseline (Week 0), Week 24 (Visit 8 = 6 months), Week 52 (Visit 15 = 12 months)
The Asthma Impairment and Risk Questionnaire (AIRQ) is a Patient Reported Outcome (PRO) tool intended to identify participants 12 years and older whose health may be at risk because of uncontrolled asthma. It has 10 questions that ask about respiratory symptoms, activity limitation, sleep, rescue medication use, social activities, exercise, difficulty controlling asthma, and exacerbations. All items have a yes/no response option and the tool is scored by summing the total number of 'yes' responses. This sum score is used to assess level of asthma control, ranging from 0 to 10, with higher scores indicating worse asthma control, where: 0-1 is well controlled, 2-4 is not well controlled, and 5-10 is very poorly controlled.

Questionnaire has 2 parts: part 1 consists of 8 items pertaining to severity of respiratory symptoms in preceding 4 weeks; part 2 consists of 42 items related to daily activity and psychosocial impacts of individual's respiratory condition. SGRQ yields a total score and 3 components scores (symptoms, activity, and impacts). Total score indicates impact of disease on overall health status, and it is expressed as percentage of overall impairment, in which 100 represents worst possible health status and 0 indicates best possible health status. Likewise, domain scores range from 0 to 100, with higher scores indicative of greater impairment.
