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.

Mean change from baseline in sino-nasal symptoms measured by SNOT-22 total score at clinical routine visits.
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).
Time frame: From Baseline up to 104 weeks, during each routine care visit
Proportion of SNOT-22 total score responders (minimal clinically important difference (MCID) from baseline = -8.9) at clinical routine visits.

Mean change from baseline in NB measured by VAS-NB at clinical routine visits.
To describe changes in nasal blockage (NB) as evaluated by a visual analog scale (VAS)-NB following initiation of tezepelumab treatment. VAS-NB is a 10-cm line with a bottom anchor of 0 = None and 10 = As bad as you can imagine. Participants will be requested to answer the following question: Please rate your \[NB\] at its worst over the previous 14 days.
Time frame: From Baseline up to 104 weeks, during clinical routine visit
Proportion of NB responders (minimal clinically important difference (MCID) from baseline = -3.0; in participants with VAS-NB ≥ 7 at baseline) at clinical routine visits.

Mean change from baseline in loss of smell score evaluated by SST-12/16.
To describe changes in sense of smell as evaluated by Sniffin Sticks Test (SST)-12/16 odours following initiation of tezepelumab treatment. SST-12/16 is a validated tool to assess the chemosensory olfactory performance of an individual. The SST is based on 12 or 16 pen-like odor dispensing devices. The participant will have to name the smell using a multiple-choice form which offers 4 answers for every pen, only one of the answers is correct. Participants with a SST-16 result will be converted to the range of SST-12 results through percentage based conversion.
Time frame: From Baseline up to 104 weeks, during clinical routine visit
Proportion of SST-16 responders (MCID from baseline = 3) at clinical routine visits.

Time frame: From Baseline up to 104 weeks, during clinical routine visit
Mean change from baseline in NP severity as measured by VAS-NP symptoms at clinical routine visits.
To describe changes in nasal polyp (NP) severity as evaluated by VAS-NP. The VAS-NP is a 10-cm line with a bottom anchor of 0 = None and 10 = As bad as you can imagine. Participants will be requested to answer the following question: Please rate your \[loss of smell\] at its worst over the previous 14 days.
Time frame: From Baseline up to 104 weeks, during clinical routine visit
