Brief Summary

ARES is a multi-centre, retrospective-prospective, non-comparative and non-interventional (observational) cohort study involving primary and secondary data collection within real-world settings of participants who have initiated tezepelumab (no more than 4 weeks before inclusion) for treatment of CRSwNP (with or without comorbid asthma).

Outcome Measures

Primary Outcomes (4)

  • 1. Change in endoscopic status of CRSwNP based on NPS

    Change in NPS score from baseline

    time points to measure: baseline and at Weeks 4, 24 and 52 following tezepelumab initiation

  • 2. Change in a nasal congestion status based on Nasal Blockage score as part of SNOT-22 (NBS-SNOT-22)

    time points to measure: baseline and at Weeks 4, 24 and 52 following tezepelumab initiation

  • 3. Change in endoscopic status of CRSwNP based on NPS

    Proportion of patients with at least a 1-point improvement in NPS score from baseline

    time points to measure: baseline and at Weeks 4, 24 and 52 following tezepelumab initiation

  • 4. Change in a nasal congestion status based on Nasal Blockage score as part of SNOT-22 (NBS-SNOT-22)

    Proportion of patients with at least a 1-point improvement in Nasal blockage score as part of SNOT-22 (NBS-SNOT-22) from baseline

  • +26 more secondary outcomes

Other Outcomes (20)

  • 1. Proportion of participants with medications for CRSwNP treatment by drug class

    time points to measure: during 52 weeks before tezepelumab initiation and up to 52 weeks following tezepelumab initiation

  • 2. Proportion of patients with InCS use

    time points to measure: during 52 weeks before tezepelumab initiation and up to 52 weeks following tezepelumab initiation

  • 3. Mean daily dose of sCS (to be calculated in participants who used sCS)

    time points to measure: during 52 weeks before tezepelumab initiation and up to 52 weeks following tezepelumab initiation

  • +17 more other outcomes

Eligibility Criteria

Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Participants of both sexes aged 18 years and older with severe nasal polyposis (NPS ≥ 5) and the need for surgery, severe nasal congestion (Nasal Blockage ≥ 3 as part of SNOT-22), significant decrease in quality of life (SNOT-22 ≥ 30) despite the use of intranasal CS, who have indications for the prescription of biological therapy, who have commenced treatment with Tezepelumab as determined by their routine clinical care, will be enrolled in the otolaryngology setting of clinical institutions in Russia. Eligible patients will be enrolled consecutively at each site to minimize selection bias at each site. The study will target to enroll no more than 20% participants switching from a prior biologic drug to Tezepelumab and no more than 60% participants with comorbid asthma.

You may qualify if:

  • Male or female participants aged 18 years or older at the time of signing the ICF.
  • Diagnosis of CRSwNP established for at least 52 weeks prior to tezepelumab initiation.
  • Availability of participants' medical records for at least 52 weeks prior to tezepelumab initiation, including history of sCS use / nasal polyps surgery (or information about contraindications / intolerance to).
  • Prescribed and initiated treatment with tezepelumab according to SmPC and local market reimbursement criteria. A period between treatment initiation and enrolment should be no more than 4 weeks.
  • The severity of CRSwNP consistent with need for surgery as defined by total NPS ≥ 5 (at least 2 for each nostril) at the enrollment.
  • Nasal Blockage score as part of SNOT-22 (NBS-SNOT-22) ≥ 3 at the enrollment.
  • SNOT-22 total score ≥ 30 at enrollment or up to 12 weeks before enrollment.
  • Currently receive care from specialist physicians (e.g., otolaryngologist) at the Investigator's or sub-Investigator's site.
  • Provision of signed and dated written informed consent.
  • Participants are able to read, understand and complete the questionnaires required by the protocol.

You may not qualify if:

  • Any contraindication to tezepelumab as per the approved product SmPC in Russia or in the opinion of the Investigator.
  • Administration of concurrent biologic drug for CRSwNP / asthma since the index date, except for stable allergen immunotherapy (defined as a stable dose and regimen at the time of enrolment). Enrolment of patients who were switched from other biologic(s) to tezepelumab is allowed, and an acceptable timeframe since the last prior biologic drug is ≥ 60 days. The number of participants with prior biologic treatment (switching to tezepelumab) should be targeted at 20% or less.
  • Participation in an observational study that might, in the Investigator's opinion, influence the assessment for the current study, or participation in an interventional clinical trial in the last 3 months.
  • Pregnancy or lactation period.
