Improved adherence with once-daily versus twice-daily dosing of mometasone furoate administered via a dry powder inhaler: a randomized open-label study

Background Poor adherence with prescribed asthma medication is a major barrier to positive treatment outcomes. This study was designed to determine the effect of a once-daily administration of mometasone furoate administered via a dry powder inhaler (MF-DPI) on treatment adherence compared with a twice-daily administration. Methods This was a 12-week open-label study designed to mimic an actual clinical setting in patients ≥12 years old with mild-to-moderate persistent asthma. Patients were randomized to receive MF-DPI 400 μg once-daily in the evening or MF-DPI 200 μg twice-daily. Adherence was assessed primarily using the number of actual administered doses reported from the device counter divided by the number of scheduled doses. Self-reports were also used to determine adherence. Health-related quality of life, healthcare resource utilization, and days missed from work or school were also reported. Results 1233 patients were randomized. The mean adherence rates, as measured by the automatic dose counter, were significantly better (P < 0.001) with MF-DPI 400 μg once-daily in the evening (93.3%) than with MF-DPI 200 μg twice-daily (89.5%). Mean adherence rates based on self-reports were also significantly better (P < 0.001) with MF-DPI 400 μg QD PM (97.2%) than with MF-DPI 200 μg twice-daily (95.3%). Adherence rates were lower in adolescents (12-17 years old). Health-related quality of life improved by 20% in patients using MF-DPI once-daily in the evening and by 14% in patients using MF-DPI twice-daily. Very few (<8%) patients missed work/school. Conclusion Mean adherence rates were greater with a once-daily dosing regimen of MF-DPI than with a twice-daily dosing regimen.

Dupilumab reduces opacification across all sinuses and related symptoms in patients with CRSwNP

BACKGROUND: Chronic rhinosinusitis with nasal polyposis (CRSwNP) is associated with substantial sinus opacification. In a phase 2a study (NCT01920893), dupilumab, a fully human anti-IL-4Rα monoclonal antibody, improved outcomes in CRSwNP refractory to intranasal corticosteroids. We evaluated dupilumab’s effect on sinus opacification in relation to effects on nasal polyp burden, symptoms, and health-related quality of life (HRQoL) in patients with CRSwNP. METHODOLOGY: 16-week randomized, double-blind, placebo-controlled, parallel-group study in 60 adults with CRSwNP. Patients received weekly subcutaneous dupilumab 300-mg or placebo and daily mometasone furoate nasal spray. Sinus opacification was assessed using standard and Zinreich-modified Lundâ€"Mackay (zLMK) scoring. Correlation was assessed between zLMK score and CRSwNP endpoints, including nasal polyp score (NPS), SNOT-22, daily symptom scores, and UPSIT smell-test score. RESULTS: Baseline characteristics were similar across treatment groups. Mean plus/minus SD baseline LMK scores of 18.7 plus/minus 5.5 (placebo) and 18.6 plus/minus 5.0 (dupilumab) indicated severe disease with extensive opacification involving all sinuses. Baseline LMK and LMK scores correlated with NPS severity and loss of sense of smell (daily symptoms; SNOT-22 smell/taste; loss of sense of smell [UPSIT]). At Week 16, dupilumab-treated patients had significantly improved sinus opacification measured by LMK in all individual sinuses vs placebo. Dupilumab also showed similar efficacy with zLMK, with only small differences from LMK, and correlated with SNOT22 smell/taste. The most common adverse events were nasopharyngitis, injection-site reactions, and headache. CONCLUSIONS: In patients with CRSwNP, baseline LMK showed extensive sinus opacification and correlated with symptoms, HRQoL, and hyposmia. Dupilumab treatment reduces opacification across all sinuses and related symptoms in patients with CRSwNP

Dupilumab improves upper and lower airway disease control in chronic rhinosinusitis with nasal polyps and asthma

Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) and type 2 asthma share the same inflammatory pathophysiology and are frequent comorbidities. Dupilumab, a fully human monoclonal antibody, blocks the shared receptor component for interleukin 4 and interleukin 13, which are key and central drivers of type 2 inflammation. Objective: We report the effect of dupilumab vs placebo on outcome measures of the upper and lower airways and health-related quality of life (HRQoL) in the pooled population of patients with CRSwNP and comorbid asthma from the phase 3 SINUS-24 (NCT02912468) and SINUS-52 (NCT02898454) studies. Methods: In these randomized, double-blind, placebo-controlled trials, patients received subcutaneous dupilumab 300 mg (n = 438) or placebo (n = 286) every 2 weeks on a background of mometasone furoate nasal spray. Changes from baseline at week 24 in the upper and lower airway outcome measures are reported. Results: Of the 724 patients randomized, 428 (59.1%) had comorbid asthma. In patients with asthma at week 24, dupilumab vs placebo improved the nasal polyp score (−2.04), patient-reported nasal congestion score (−1.04), Lund-Mackay computed tomography scan score (−6.43), peak nasal inspiratory flow (46.15 L/min), and 22-item sinonasal outcome test score (−21.42; all P < .001). The forced expiratory volume in 1 second and 6-item asthma control questionnaire scores were also markedly improved with dupilumab vs placebo. The most common adverse events (nasopharyngitis, headache, injection-site erythema, worsening of nasal polyposis, and asthma) were more frequent with placebo than dupilumab. Conclusion: Dupilumab improved upper and lower airway outcome measures and HRQoL in patients with severe CRSwNP and comorbid asthma and was well tolerated.

Olfactory Outcomes with Dupilumab in Chronic Rhinosinusitis with Nasal Polyps

Background: Loss of smell (LoS) is one of the most troublesome and difficult-to-treat symptoms of severe chronic rhinosinusitis with nasal polyps (CRSwNP). Objective: To assess the impact of dupilumab on sense of smell in severe CRSwNP. Methods: In the randomized SINUS-24 and SINUS-52 studies, adults with severe CRSwNP received dupilumab 300 mg subcutaneously or matching placebo every 2 weeks for 24 or 52 weeks, respectively. Smell was assessed using daily patient-reported LoS score (0–3) and University of Pennsylvania Smell Identification Test (UPSIT; 0–40). Data from the 2 studies were pooled through week 24. Relationships between patient phenotypes and smell outcomes were also assessed. Results: We randomized 724 patients (286 placebo, 438 dupilumab); mean CRSwNP duration was 11 years; 63% had prior sinonasal surgery. Mean baseline LoS was 2.74. Dupilumab produced rapid improvement in LoS, evident by day 3, which improved progressively throughout the study periods (least squares mean difference vs placebo −0.07 [95% CI −0.12 to −0.02]; nominal P < .05 at day 3, and −1.04 [−1.17 to −0.91]; P < .0001 at week 24). Dupilumab improved mean UPSIT by 10.54 (least squares mean difference vs placebo 10.57 [9.40–11.74]; P < .0001) at week 24 from baseline (score 13.90). Improvements were unaffected by CRSwNP duration, prior sinonasal surgery, or comorbid asthma and/or nonsteroidal anti-inflammatory drug–exacerbated respiratory disease. Baseline olfaction scores correlated with all measured local and systemic type 2 inflammatory markers except serum total immunoglobulin E. Conclusions: Dupilumab produced rapid and sustained improvement in sense of smell, alleviating a cardinal symptom of severe CRSwNP

Dupilumab in patients with prurigo nodularis: two randomized, double-blind, placebo-controlled phase 3 trials

Prurigo nodularis (PN) is a chronic inflammatory skin disease with intensely pruritic nodules. The LIBERTY-PN PRIME and PRIME2 phase 3 trials enrolled adults with PN with ≥20 nodules and severe itch uncontrolled with topical therapies. Dupilumab, a fully human monoclonal antibody, blocks the shared receptor component for interleukin (IL)-4 and IL-13. Patients were randomized 1:1 to 300 mg dupilumab or placebo subcutaneously every 2 weeks for 24 weeks. The primary endpoint was pruritus improvement, measured by proportion of patients with a ≥4-point reduction in Worst Itch Numeric Rating Scale (WI-NRS) from baseline at week 24 (PRIME) or week 12 (PRIME2). Key secondary endpoints included nodule number reduction to ≤5 at week 24. PRIME and PRIME2 enrolled 151 and 160 patients, respectively. Both trials met all the pre-specified primary and key secondary endpoints. A ≥4-point WI-NRS reduction at week 24 in the dupilumab and placebo arms was achieved by 60.0% and 18.4% of patients, respectively, in PRIME (95% confidence interval (CI), 27.8-57.7 for the difference, P < 0.001) and at week 12 by 37.2% and 22.0% of patients, respectively, in PRIME2 (95% CI, 2.3-31.2; P = 0.022). Dupilumab demonstrated clinically meaningful and statistically significant improvements in itch and skin lesions versus placebo in PN. Safety was consistent with the known dupilumab safety profile.ClinicalTrials.gov identifiers: NCT04183335 and NCT04202679

Dupilumab improves patient-reported outcomes in patients with chronic rhinosinusitis with nasal polyps and comorbid asthma

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a common inflammatory condition affecting the upper airways, with chronic symptoms such as nasal congestion, partial (hyposmia) or total (anosmia) loss of smell, anterior/posterior rhinorrhea, and mild facial pain.1 As many as 66% of patients with CRSwNP have comorbid asthma and suffer from more severe nasal obstruction, higher levels of lower airway inflammation, and worse asthma control than those without CRS.2, 3 Thus, patients with CRSwNP and comorbid asthma have a high disease burden, seriously impacting health-related quality of life (HRQoL).2, 3 Markers of type 2-mediated inflammation and antibody production (eg, IL-5, IgE) are associated with both CRSwNP and asthma pathogenesis.

Dupilumab improves health-related quality of life in patients with chronic rhinosinusitis with nasal polyposis

BACKGROUND: Chronic rhinosinusitis with nasal polyposis (CRSwNP) negatively affects health-related quality of life (HRQoL). In a previously reported randomized clinical trial (NCT01920893), addition of dupilumab to mometasone furoate in patients with CRSwNP refractory to intranasal corticosteroids (INCS) significantly improved endoscopic, radiographic, and clinical endpoints and patient-reported outcomes. The objective of this analysis was to examine the impact of dupilumab treatment on HRQoL and productivity using secondary outcome data from this trial. METHODS: Following a 4-week mometasone furoate nasal spray run-in, patients were randomized to commence subcutaneous dupilumab (600 mg loading dose, then 300 mg once weekly for 15 weeks [n = 30], or matched placebo [n = 30]). Outcomes included scores on the CRS disease severity visual analog scale (VAS), 22-item Sino-Nasal Outcome Test (SNOT-22), 5-dimension EuroQoL (EQ-5D) general health status VAS, and 36-item Short-Form Health Survey (SF-36) for HRQoL and nasal polyp-related healthcare resource use questionnaires. RESULTS: Following 16 weeks of treatment, the proportion of patients with moderate-to-severe CRSwNP (VAS > 3-10) decreased from 86.2% to 21.4% with dupilumab and 88.0% to 84.2% with placebo. Dupilumab (vs placebo) resulted in significantly greater improvement in HRQoL, based on SNOT-22, SF-36, and EQ-5D VAS scores. The dupilumab group had a significantly lower adjusted annualized mean number of sick leave days (0.09, vs 4.18 with placebo, P = .015) and significantly greater improvement (vs placebo) in the SNOT-22 item "reduced productivity." CONCLUSIONS: In adults with CRSwNP refractory to treatment with INCS alone, the addition of dupilumab reduced disease severity, significantly improved HRQoL, and improved productivity.status: publishe
