The Choice of Biologics in Patients with Severe Chronic Rhinosinusitis with Nasal Polyps

Patients with severe chronic rhinosinusitis with nasal polyps represent an unmet clinical need in terms of recurrent disease despite current medical and surgical therapy. Targeting type 2 inflammatory cytokines (IL 4/5/13) appears to be a promising therapeutic approach for such patients akin to what has already been seen in severe asthma. An indirect comparison from phase 3 placebo-controlled trials has shown relative improvements in the coprimary end point of nasal polyp score (NPS) ranging from a 15% reduction ( - 0.8 units) with mepolizumab, 18% with omalizumab (-1.14 units), and 35% ( - 2.06 units) with dupilumab. This trend was mirrored by relative improvements in health status with the 22-item Sinonasal Outcome Test score showing a 21% reduction ( -13.7 units) with mepolizumab, 27% ( -16.1 units) with omalizumab, and 43% (- 21.1 units) with dupilumab, all exceeding the minimal clinically important difference of 8.9 units. All biologics improved the coprimary end point of nasal airway blockage and also reduced the need for rescue medical and/or surgical polypectomy. We advocate performing real-life studies looking at the response to biologics in patients who are at increased risk for disease recurrence, including initial optimal medical and surgical polyp clearance before commencing biologics.
