Nasal polyposis is a chronic inflammatory disease of the nose and sinuses. GlaxoSmithKline (GSK) is embarking on a clinical program to assess treatment of severe, recurrent nasal polyps with an anti-interleukin-5 (anti-IL5) (mepolizumab). Subject specific symptomatic endpoints will form the basis for the assessment of treatment benefit of nasal polyp therapies. However, there is a lack of published qualitative data regarding nasal polyps to understand the symptoms or health-related quality of life (HRQoL) impacts. This cross-sectional qualitative study aims to address this unmet gap by conducting semi-structured combined concept elicitation (CE) and cognitive debriefing (CD) telephone interviews and real-time data capture. The combined CE and CD interviews (each 90 minutes in duration) will investigate the subject experience of nasal polyps, and the relevance and understanding of existing patient-reported outcomes (PRO) instruments. The real-time data capture conducted over a 10 day period, will investigate the subject experience of the symptoms, HRQoL impacts and treatment of nasal polyps and any day-to-day variability that exists in these experiences in 'real time'. Twenty adult subjects in the United States (US), and 10 adult subjects in Germany with severe, recurrent nasal polyps will participate in the CE and CD interviews section of the study and of these, 10 subjects from US will also complete real-time data capture app task.
Study Type
OBSERVATIONAL
Enrollment
27
VAS questionnaire is a PRO tool in which subjects will be asked to evaluate overall symptom severity, or the severity of individual symptoms of nasal polyps along a continuum, typically of 10 centimeter (cm) or 100 millimeter (mm) whereby 0 represents 'no symptom' and '10 or 100 represents 'as bad as you can imagine', Scores of 0-3 (or 0-30) are defined as mild disease, \>3-7 (or \>30-70) as moderate disease and \>7-10 (or \>70-100) as severe disease.
SNOT-22 is a PRO tool to measure HRQoL associated with rhinosinusitis with or without nasal polyps. It contains 22 nose, sinus, and general HRQoL items and subjects will be required to score the experience on a 6-point scale ranging from 0 (no problem) to 5 (Problem as bad as it can be) and identify the five most important items affecting their health.
Real time data capture app is a smart-phone or web-based application which will allow the subjects to communicate about their experience of nasal polyps in real-time as they go about their daily lives via varying video, audio, photographic and text responses.

Number of Participants Who Reported Primary Symptoms
During the CE section of the interview, participants were asked a series of broad open-ended questions designed to encourage them to talk openly and as spontaneously as possible about their experience of having nasal polyps. In addition, participants were asked more focused questions designed to probe on issues that they may not have mentioned during the course of the interview spontaneously or concepts/statements that required additional clarification. The interviews were transcribed/translated verbatim and qualitative analysis was conducted using Atlas Ti.
