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 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.
• \- Participant must be 18 years of age or older, at the time of signing the informed consent.
• \- Confirmed diagnosis of CRSwNP for at least 12 months prior to routine care visit 1.
• \- Stable standard of care (SoC) treatment with Intranasal corticosteroids (INCS) for CRSwNP for at least 30 days prior to routine care visit 1.
• \- Physician decision that participant is eligible for treatment with Tezepelumab according to locally approved CRSwNP label.
• Participants must be able and willing to read and comprehend written instructions, to collect Patient-reported outcome (PROs) and medication intake via app or alternative mode (paper) and to sign the informed consent document. Use of the mobile app is optional; participants without smartphones will not be excluded. Mode of data capture will be recorded and adjusted for in analyses where relevant.
