About this study

Official title: POLARIS: A Prospective, Multicenter Real-World Study to Investigate the Treatment Pattern and Prognostic Outcome in Chinese Severe Chronic Rhinosinusitis With Nasal Polyps (CRSwNP) Patients

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a long-lasting inflammatory disease of the nose and sinuses that can cause nasal blockage, loss of smell, nasal discharge, facial discomfort, sleep problems, and reduced quality of life.

POLARIS is a prospective, multicenter, real-world, non-interventional registry study. It will enroll approximately 1,000 adolescents and adults aged 12 years or older with bilateral CRSwNP at about 33 centers in China and follow them for 36 months. All treatment decisions will be made by the treating physicians according to routine clinical practice. The study will not assign participants to any treatment.

The study aims to describe the disease burden, underlying inflammatory characteristics, real-world treatment patterns, effectiveness of current treatments, and long-term outcomes of Chinese patients with CRSwNP. Key assessments will include changes in nasal symptoms measured by the Total Nasal Symptom Score, changes in disease-related quality of life measured by the 22-item Sino-Nasal Outcome Test, and the proportions of patients classified as cured, controlled, or uncontrolled at months 12, 24, and 36. The study will also examine treatment escalation, surgery, systemic corticosteroid and biologic use, health care and economic burden, safety events, and clinical characteristics and biomarkers associated with persistent high disease burden or frequent treatment escalation.

Read the detailed description

This is a prospective, multicenter, real-world, non-interventional longitudinal registry study conducted at approximately 33 centers in China. Approximately 1,000 participants aged 12 years or older with bilateral chronic rhinosinusitis with nasal polyps (CRSwNP) will be followed for 36 months. Eligible participants must meet the protocol-defined diagnostic, nasal polyp score, and symptom criteria.

Participants will receive standard medical care as determined by their treating physicians. No treatment will be assigned by the study, and participation will not restrict or otherwise determine the use of medical therapy, systemic corticosteroids, biologic therapy, endoscopic sinus surgery, or other clinically indicated treatment.

The study uses a combination of scheduled and event-driven in-person visits and telephone follow-up. Scheduled in-person visits are planned at Months 3, 6, 9, 12, 18, 24, 30, and 36, and telephone visits are planned at Months 15, 21, 27, and 33.

During follow-up, participants with worsening symptoms, defined as persistent NCS of at least 2, LoS of at least 2, or SNOT-22 of at least 30 during the previous week, will have an additional in-person visit within a window of ±2 weeks to determine whether treatment escalation is needed.

Participants undergoing endoscopic sinus surgery will have an additional in-person visit approximately 2 weeks after surgery. Participants receiving a protocol-defined oral corticosteroid course of at least 7 days at a daily dose of at least 30 mg prednisone equivalent will have an additional in-person visit approximately 2 weeks after corticosteroid discontinuation. Each post-treatment visit has a window of ±2 weeks. If a participant receives two or more qualifying escalation treatments, the earliest applicable post-treatment time point will be used. Biologic initiation or switching does not trigger this additional 2-week visit.

Collected information will include demographic and clinical characteristics, medical and surgical history, comorbidities, treatment patterns, symptom scores, disease-related quality of life, nasal polyp assessments, treatment outcomes, treatment escalation events, health care resource use, economic and humanistic burden, and safety events. Laboratory results and biological specimens, including blood, nasal polyp tissue, nasal cells, and nasal secretions, may be collected as specified in the protocol and when applicable.

The primary assessments describe changes from baseline in the Total Nasal Symptom Score and the 22-item Sino-Nasal Outcome Test, and the proportions of participants classified as cured, controlled, or uncontrolled at months 12, 24, and 36. Secondary and exploratory analyses will describe treatment escalation, surgery, systemic corticosteroid and biologic use, clinical and biomarker changes, and factors associated with persistent high disease burden or frequent treatment escalation. The primary analyses will be descriptive; exploratory statistical models may be used to evaluate associations between participant characteristics, biomarkers, treatment patterns, and outcomes.

Study personnel will receive standardized protocol and data collection training. Data will be entered into an electronic data capture system with role-based access, predefined range and consistency checks, an audit trail, and investigator confirmation. Data queries, periodic monitoring, and data quality reviews will be used to address missing, inconsistent, or implausible information and to support adherence to the protocol and protection of participant privacy.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Routine Clinical Care for CRSwNPOther

    Participants may receive any clinically indicated treatment for CRSwNP according to routine clinical practice, including intranasal corticosteroids, systemic corticosteroids, endoscopic sinus surgery, biologic therapies, and other appropriate management. Treatment selection, initiation, switching, discontinuation, and escalation are determined by the treating physicians. The study does not provide or assign any treatment; it observes real-world treatment patterns and associated clinical outcomes over 36 months.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change From Baseline in 22-Item Sino-Nasal Outcome Test (SNOT-22) Total Score

    The SNOT-22 is a 22-item patient-reported questionnaire assessing disease-related quality of life. Each item is scored from 0 to 5, giving a total score from 0 to 110, with higher scores indicating greater impairment. Change in the total score from baseline will be summarized at each specified time point.

    Measured: Baseline and Months 12, 24, and 36

  2. Change From Baseline in Total Nasal Symptom Score (TNSS)

    TNSS is recorded daily by participants using a paper symptom diary. The visit-level TNSS total score and component scores will generally be derived from diary entries completed during the 14 consecutive days before each visit. Change from baseline will be summarized at each specified time point.

    Measured: Baseline and Months 12, 24, and 36

  3. Percentage of Participants in Each CRSwNP Treatment Outcome Category

    At each time point, participants will be classified as cured, controlled, or uncontrolled according to protocol-defined criteria.

    Cured is defined as having no rhinosinusitis-related symptoms and no mucosal edema, nasal polyps, or abnormal secretions on nasal endoscopy for 6 months without treatment intervention.

    Controlled is defined as having no rhinosinusitis-related symptoms for 6 months while receiving treatment intervention, with a Nasal Polyp Score (NPS) of <=1 on each side.

    Uncontrolled disease is defined as the persistence of rhinosinusitis-related symptoms despite treatment, indicated by a weekly mean Nasal Congestion Score (NCS) of at least 2 or a weekly mean Loss of Smell Score (LoS) of at least 2, or a Nasal Polyp Score (NPS) greater than 1 on either side.
