Временное ограничение
Annualized Asthma Exacerbation Rate (AAER)
Временное ограничение: 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)].

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.

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.

Описание плана IPD

Квалифицированные исследователи могут запросить доступ к анонимным данным отдельных пациентов у группы компаний AstraZeneca, спонсирующих клинические испытания, через портал запросов. Все запросы будут оцениваться в соответствии с обязательством AZ по раскрытию информации:

https://astrazenecagrouptrials.pharmacm.com/ST/Submission/Disclosure. Да, указывает, что AZ принимает запросы на IPD, но это не означает, что все запросы будут общими.

Сроки обмена IPD

«АстраЗенека» будет соответствовать или превышать доступность данных в соответствии с обязательствами, принятыми в Принципах обмена данными EFPIA Pharma. Подробную информацию о наших сроках см. в нашем обязательстве по раскрытию информации по адресу https://astrazenecagrouptrials.pharmacm.com/ST/Submission/Disclosure.

Критерии совместного доступа к IPD

Когда запрос будет одобрен, AstraZeneca предоставит доступ к деидентифицированным данным на уровне отдельных пациентов в утвержденном спонсируемом инструменте. Перед доступом к запрошенной информации должно быть заключено подписанное соглашение об обмене данными (не подлежащий обсуждению контракт для лиц, осуществляющих доступ к данным). Кроме того, все пользователи должны будут принять условия SAS MSE, чтобы получить доступ.
