May 11, 2026 updated by: AstraZeneca

PREDICT: A Prospective, Multicenter Real-World Study to Describe the Clinical Outcome and Quality of Life in Chinese CRSwNP Patients

This is a prospective, multicenter real-world study to describe the postoperative outcomes and quality of life, disease control and characteristics of patients who underwent surgery, as well as economic burden and post-operative treatment patterns in Chinese patients with CRSwNP recurrence.

Study Overview

Detailed Description

This is a prospective, multicenter real-world study to describe the postoperative outcomes and quality of life, disease control and characteristics of patients who underwent surgery, as well as economic burden and post-operative treatment patterns in Chinese patients with CRSwNP. Patients will receive standard medical care as determined by the treating physician at each site and undergo scheduled clinical assessments.

Approximately 200 patients diagnosed with CRSwNP by physicians and scheduled for surgical treatment will be enrolled across 20 centres in different regions of China.

Design Details

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Standard of Care Endoscopic Sinus Surgery (ESS)

Although this study is non-interventional and observational in nature regarding treatment decisions, it is registered as an interventional study focusing on the Standard-of-Care (SoC) Functional Endoscopic Sinus Surgery (FESS) as the index procedure.

The "intervention" serves as the baseline event for the prospective evaluation of real-world outcomes. The study aims to assess the clinical trajectory (including SNOT-22, Nasal Polyp Score, and CT findings) following this standard clinical procedure over a 52-week period.

The surgery is performed strictly according to clinical routine, local guidelines, and the investigator's professional discretion.

This is a standard of care surgical procedure performed according to clinical routine. No experimental treatment or investigational drug is administered as part of this study.
