Mepolizumab improvements in health-related quality of life and disease symptoms in a patient population with very severe chronic rhinosinusitis with nasal polyps: psychometric and efficacy analyses from the SYNAPSE study
Plain English summary Patients with chronic rhinosinusitis (CRS) often have blocked or runny noses, and loss of sense of smell. They can also have sac-like growths in their nose called nasal polyps, which often require surgical removement. The symptoms of CRS with nasal polyps can affect quality of life. In a clinical study named SYNAPSE, a new treatment option called mepolizumab reduced the size and severity of nasal polyps in patients suffering from very severe CRS with nasal polyps, compared with placebo. Mepolizumab also reduced the need for nasal polyp surgery. The SYNAPSE study also measured if 1 year of mepolizumab treatment improved patients’ symptoms and quality of life. This was evaluated by asking patients to complete two separate tasks. These tasks were rating symptoms on a visual analogue scale (VAS) and completing a quality of life questionnaire called SNOT-22. The objective of this analysis was to see if these questionnaires accurately assessed a patient’s quality of life. The analysis also assessed how many patients had major improvements in their symptoms with mepolizumab. Overall, data from 407 patients in the SYNAPSE study was analyzed. Results showed that both the VAS and SNOT-22 questionnaires accurately captured CRS symptoms and quality of life. In addition, patients treated with mepolizumab for 1 year had improvements in quality of life compared with placebo. In conclusion, these findings suggest that the VAS and SNOT-22 questionnaires are appropriate evaluation tools for patients with very severe CRS with nasal polyps. The findings also show that mepolizumab treatment is beneficial for these patients.
