About

The objective of the study is to establish a registry of patients diagnosed with Chronic Rhinosinusitis with and without Nasal Polyps (CRSwNP/CRSsNP) to collect comprehensive longitudinal real-world evidence from specialised treatment centres in Germany. The primary analysis will concentrate on the treatment efficacy and safety of biologic drugs with a focus on defining disease Control, Remission, and Cure as well as to validate the corresponding clinical evaluation criteria.

Full description

The German national CRS registry (Genre CRS) is a nationwide registry for patients with CRSsNP and CRSwNP that aims to include more than 250 centres in Germany. Genre CRS is operated by the German Societies of Allergology (AeDA) and Otorhinolaryngology (DGHNO) and is based on most advanced digital health technologies, including a wide variety of collected parameters. Additionally, patient-reported outcome measures will be captured via a smart phone app and submitted directly to the registry database. This registry is the first of its kind in Germany. It will be the foundation for answering many critical/pivotal research questions that depend on high quality, extensive longitudinal data provided by the registry for future studies.

One important field of application will be the long-term assessment of RWE on therapeutic antibodies, also known as "biologics". Biologics are a novel treatment option for patients with severe CRSwNP and have led to tremendous treatment success. Chronically ill patients with a long history of severe symptoms and impaired quality of life can now experience a significant improvement in CRSwNP symptoms when treated with a biologic, which has prompted the discussion about disease Control, Remission, and even Cure. So far, internationally accepted and clinically evaluated definitions of these terms are lacking, but would greatly assist clinicians in developing therapeutic strategies, particularly for the long-term management of chronically affected patients. The criteria currently in use, although generally accepted, are not evidence-based and do not reflect the perspectives of patients and healthcare providers. An international expert working group of the European Academy for Allergy and Clinical Immunology (EAACI) has therefore developed such criteria, which now need to be clinically evaluated and validated using the comprehensive longitudinal data from Genre CRS.

Data collection includes a variety of parameters involved in the treatment with biologics, analysis of their long-term efficacy and safety including but not limited to:

Polyp Size
SNOT22
Visual analog scales for nasal congestion, rhinorrhea, pressure/facial pain, sense of smell
Olfactory function
Necessity for rescue treatment (sinus surgery, OCS)
Parameters of co-morbid diseases
Type 2 biomarkers
