Efficacy of EDS-FLU for Chronic Rhinosinusitis: Two Randomized Controlled Trials (ReOpen1 and ReOpen2).

Chronic rhinosinusitis (CRS) is a prevalent inflammatory disease. No medications are Food and Drug Administration-approved for the most common form, CRS without nasal polyps (also called "chronic sinusitis"). Novel biomechanics of the exhalation delivery system deliver fluticasone (EDS-FLU; XHANCE) to sinonasal areas above the inferior turbinate, especially sinus drainage pathways not reached by standard-delivery nasal sprays.Assess EDS-FLU efficacy for CRS (irrespective of nasal polyps).Two randomized, EDS-placebo-controlled trials in adults with CRS irrespective of polyps (ReOpen1) or exclusively without polyps (ReOpen2) were conducted at 120 sites in 13 countries. Patients received EDS-FLU 1 or 2 sprays/nostril, or EDS-placebo, twice daily for 24 weeks. Coprimary measures were composite symptom score through week 4 and ethmoid/maxillary sinus percent opacification by computed tomography at week 24.ReOpen1 (N = 332) composite symptom score least-squares mean change for EDS-FLU 1 or 2 sprays/nostril versus EDS-placebo was -1.58 and -1.60 versus -0.62 (P < .001, P < .001); ReOpen2 (N = 223), -1.54 and -1.74 versus -0.81 (P = .011, P = .001). In ReOpen1, sinus opacification least-squares mean change for EDS-FLU 1 or 2 sprays/nostril versus EDS-placebo was -5.58 and -6.20 versus -1.60 (P = .045, P = .018), and in ReOpen2, -7.00 and -5.14 versus +1.19 (P < .001, P = .009). Acute disease exacerbations were reduced by 56% to 66% with EDS-FLU versus EDS-placebo (P = .001). There were significant, and similar magnitude, symptom reductions in patients using standard-delivery nasal steroid products just before entering the study (P < .001). Adverse events were similar to standard-delivery intranasal steroids.EDS-FLU is the first nonsurgical treatment demonstrated to reduce symptoms, intrasinus opacification, and exacerbations in replicate randomized clinical trials in CRS, regardless of polyp status.
