Prospective, Non-interventional Single-arm Study With Tezepelumab to Investigate the Change in Clinical and Patient-reported Outcomes in Patients With CRSwNP in Real-world (PETRICHOR) (PETRICHOR)

maanantai 24. elokuuta 2026 päivittänyt: AstraZeneca
PETRICHOR is a prospective, non-interventional, single-arm, multi-centre study in Germany evaluating real-world clinical and patient-reported outcomes in adults with severe chronic rhinosinusitis with nasal polyps (CRSwNP), whose disease is inadequately controlled with systemic corticosteroids (SCS) and/or surgery. Eligible participants are newly initiated on subcutaneous tezepelumab in routine clinical practice, in accordance with the European Summary of Product Characteristics (SmPC). Treatment decisions are made jointly by patients and their physicians, independent of study enrollment. No additional diagnostic or monitoring procedures are applied; data are collected using epidemiological methods at baseline and during routine clinical visits for up to 104 weeks.

Tutkimusväestö

The study population will consist of male and female participants aged ≥ 18 years treated by ear-nose-throat specialists with diagnosed severe uncontrolled CRSwNP, for whom a tezepelumab biologic treatment for CRSwNP will be initiated in line with the applicable European Summary of Product Characteristics (SmPC) within routine clinical practice. The decision to initiate or switch to Tezepelumab must be made by the treating physician according to the participant's medical needs and a positive benefit/risk balance. Eligible patients will be included into the study after and independently of the treating physician's treatment and diagnostic decisions. Each participant should meet all the Inclusion Criteria and none of the Exclusion Criteria for this study in order to be part of the study.

Ensisijaiset tulostoimenpiteet

Tulosmittaus
Toimenpiteen kuvaus
Aikaikkuna
Mean change from baseline in sino-nasal symptoms measured by SNOT-22 total score at clinical routine visits.
Aikaikkuna: From Baseline up to 104 weeks, during each routine care visit

To describe changes from baseline in patient-reported sino-nasal symptoms as evaluated by Sinonasal outcome test (SNOT)-22 total score following initiation of tezepelumab treatment.

SNOT-22 scores are participant-reported and assess physical problems, functional limitations and emotional consequences of SinoNasal conditions. Patient-reported symptom severity and symptom impact over the past 2 weeks are captured via a 6-point scale (0-No Problem to 5-Problem as bad as it can be). The total score is the sum of item scores and has a range from 0 to 110 (higher scores indicate poorer outcomes).
