Detaillierte Beschreibung

Dies ist eine multizentrische, einarmige, unverblindete Phase-4-Studie nach der Zulassung zur Bewertung der Wirksamkeit von Tezepelumab in den Vereinigten Staaten (USA) bei einer realen Population von Erwachsenen und jugendlichen Teilnehmern mit Asthma, die eine mittlere Dosis benötigen bis zu hochdosierten inhalativen Kortikosteroiden (ICS) mit zusätzlichen Controllern für mindestens 12 Monate mit dokumentierter Anamnese von mindestens 2 Asthma-Exazerbationen im Laufe des Jahres. Die Gesamtdauer der Studie für jeden Teilnehmer wird etwa 56 Wochen betragen. Etwa 400 Teilnehmer werden eingeschrieben sein. Die Teilnehmer erhalten Tezepelumab über einen Behandlungszeitraum von 48 Wochen als subkutane Injektion am Studienort. Die Studie umfasst auch eine Nachbeobachtungszeit nach der Verabreichung von Woche 48 bis 52.

Maßnahmenbeschreibung
Zeitfenster
Annualized Asthma Exacerbation Rate (AAER)
Zeitfenster: 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.

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.

Plan für individuelle Teilnehmerdaten (IPD)

Planen Sie, individuelle Teilnehmerdaten (IPD) zu teilen?

JA

Beschreibung des IPD-Plans

Qualifizierte Forscher können über das Anfrageportal Zugang zu anonymisierten individuellen Patientendaten aus von der AstraZeneca-Unternehmensgruppe gesponserten klinischen Studien anfordern. Alle Anfragen werden gemäß der AZ-Offenlegungsverpflichtung bewertet:

https://astrazenecagrouptrials.pharmacm.com/ST/Submission/Disclosure. Ja, zeigt an, dass AZ Anfragen für IPD akzeptiert, aber das bedeutet nicht, dass alle Anfragen geteilt werden.

IPD-Sharing-Zeitrahmen

AstraZeneca erfüllt oder übertrifft die Datenverfügbarkeit gemäß den Verpflichtungen der EFPIA Pharma Data Sharing Principles. Einzelheiten zu unseren Fristen finden Sie in unserer Offenlegungsverpflichtung unter https://astrazenecagrouptrials.pharmacm.com/ST/Submission/Disclosure.

IPD-Sharing-Zugriffskriterien

Wenn eine Anfrage genehmigt wurde, gewährt AstraZeneca Zugriff auf die anonymisierten Daten auf Patientenebene in einem genehmigten gesponserten Tool. Eine unterzeichnete Datenfreigabevereinbarung (nicht verhandelbarer Vertrag für Datenzugriffsberechtigte) muss vorhanden sein, bevor auf angeforderte Informationen zugegriffen werden kann. Darüber hinaus müssen alle Benutzer die Geschäftsbedingungen der SAS MSE akzeptieren, um Zugriff zu erhalten.
