Dupilumab response onset, maintenance, and durability in patients with severe CRSwNP.

BACKGROUND: Responder analyses of SINUS phase 3 study data have shown clinically meaningful improvements across multiple chronic rhinosinusitis with nasal polyps (CRSwNP) outcomes with dupilumab. OBJECTIVE: To gain a better understanding of dupilumab response dynamics over 52 weeks. METHODS: Post hoc analysis using data from the SINUS-52 (NCT02898454) intention-to-treat population, of patients with severe CRSwNP who received dupilumab 300 mg once every 2 weeks (q2w) or placebo. Response, defined as an improvement from baseline of ≥ 1 point for Nasal Polyp Score (NPS), nasal congestion (NC), and loss of smell (LoS), and ≥ 8.9 points for 22-item Sino-Nasal Outcome Test (SNOT-22), was assessed for rapidity, maintenance, and durability. RESULTS: 303 patients (dupilumab, n = 150; placebo, n = 153) were included. For each outcome measure, a greater proportion of patients achieved first response by Week 16 (rapidity) with dupilumab vs placebo: NPS, 75.3% vs 39.2%; NC, 60.0% vs 24.2%; LoS, 60.7% vs 15.7%; and SNOT-22, 83.3% vs 66.0%. Among dupilumab patients with a response by Week 16, more than 80% maintained response at Week 52 (maintenance). Over 52 weeks, greater proportions of dupilumab patients were responders at ≥ 80% of time points: NPS, 46.7% vs 2.6%; NC, 46.7% vs 9.2%; LoS, 47.3% vs 3.9%; and SNOT-22, 62.0% vs 21.6% (durability). CONCLUSION: Most CRSwNP patients achieve clinically meaningful responses to dupilumab by Week 16, and most of these patients had maintenance and durability of response with continued treatment over time.

Effect of avalglucosidase alfa on disease-specific and general patient-reported outcomes in treatment-naïve adults with late-onset Pompe disease compared with alglucosidase alfa: Meaningful change analyses from the Phase 3 COMET trial.

BACKGROUND: The Phase 3 COMET trial (NCT02782741) comparing avalglucosidase alfa and alglucosidase alfa included health-related quality of life (HRQoL) assessments in treatment-naïve patients with late-onset Pompe disease (LOPD). Here, we further characterize results from disease-specific and general patient-reported outcome (PRO) measures. METHODS: Adults who participated in the COMET trial receiving avalglucosidase alfa or alglucosidase alfa (both 20 mg/kg biweekly) during the 49-week double-blind treatment period were included in the analysis. Proportions of patients exceeding meaningful change thresholds at Week 49 were compared post hoc between treatment groups. PROs and their meaningful change thresholds included: Pompe Disease Severity Scale (PDSS; decrease 1.0-1.5 points), Pompe Disease Impact Scale (PDIS; decrease 1.0-1.5 points), Rasch-built Pompe-specific Activity Scale (R-PAct; change from unable to able to complete activity), 12-item Short Form Health Survey (SF-12; physical component summary [PCS] score: increase ≥6 points, mental component summary [MCS] score: increase ≥7 points), EuroQol 5 Dimension 5 Level (EQ-5D-5L; improvement of ≥1 category), and Patient Global Impression of Change (PGIC; any improvement). RESULTS: The analysis included 99 adult patients (avalglucosidase alfa n = 50; alglucosidase alfa n = 49). Patients who received avalglucosidase alfa had significantly greater odds of achieving a meaningful change versus alglucosidase alfa for the PDSS Shortness of Breath (OR [95% CI] 11.79 [2.24; 62.18]), Fatigue/Pain (6.24 [1.20; 32.54]), Morning Headache (13.98 [1.71; 114.18]), and Overall Fatigue (5.88 [1.37; 25.11]) domains, and were significantly more likely to meet meaningful change thresholds across multiple PDSS domains (all nominal p < 0.05). A numerically greater proportion of patients in the avalglucosidase alfa group were able to complete selected activities of the R-PAct compared with the alglucosidase alfa group. Significantly greater proportions of patients who received avalglucosidase alfa achieved meaningful improvements for EQ-5D-5L usual activities dimension, EQ visual analog scale, and all four PGIC domains. The proportion of patients with improvements in SF-12 PCS and MCS was greater in the avalglucosidase alfa group versus alglucosidase alfa group, but was not significant (p > 0.05). CONCLUSIONS: These analyses show that avalglucosidase alfa improves multiple symptoms and aspects of daily functioning, including breathing and mobility. This supports the clinical relevance of the effects of avalglucosidase alfa on HRQoL for patients with LOPD.

Validation of a scoring algorithm for the clinician-reported outcome tool 'prurigo activity and severity (PAS)' based on clinical studies of dupilumab in adults with prurigo Nodularis.

BACKGROUND: Prurigo nodularis (PN) also known as chronic prurigo, is a chronic inflammatory skin disease characterized by intensely itchy nodules/lesions which occur due to intensive scratching. PN management is, in part, based on clinician evaluations of PN lesions, which can be supported by clinician-reported outcomes (ClinRO) such as the Prurigo Activity and Severity (PAS) instrument. A 5-item version of PAS was included in recent phase-3 dupilumab PN trials (PRIME [NCT04183335]/PRIME2 [NCT04202679]). The PAS score was derived using the unweighted sum of 3-items of the 5-item PAS (range, 0-11; higher score indicates worse activity and severity): Item 2 (number of lesions), Item 5a (percentage of lesions with excoriations/crusts) and Item 5b (percentage of healed lesions) for use in clinical practice and for communication of treatment benefit to physicians. OBJECTIVES: To evaluate the measurement properties of PAS score and derive within-patient (responder definition) and between-group improvement thresholds for interpreting changes in PAS score in patients with PN. METHODS: The data source was the pooled treatment group, intention-to-treat (ITT) data from the phase-3 PRIME (NCT04183335) and PRIME2 (NCT04202679) studies evaluating the efficacy of dupilumab in adult patients with PN with ≥20 nodules and severe itch uncontrolled with topical therapies. PAS score reliability, validity and sensitivity to change were evaluated, and anchor- and distribution-based methods were applied to derive meaningful change thresholds. RESULTS: The pooled ITT population included 311 patients (mean age 49.5 years, 65.3% female). Adequate to good psychometric properties were demonstrated for PAS score. The within-patient meaningful improvement threshold was estimated as 3.0 points (absolute change) and 37% (per cent change). A 1.7-point (absolute change) and 20% (per cent change) improvement were estimated to reflect a between-group meaningful change in PAS score. CONCLUSIONS: PAS score is a simple, clinically relevant indicator of PN lesion activity and severity supported by suitable psychometric performance.

Responder analysis using clinically meaningful thresholds: Post hoc analyses from randomized dupilumab clinical trials in patients with prurigo nodularis.

BACKGROUND: Prurigo nodularis (PN) is an intensely pruritic disease characterized by itchy nodules on the trunk/extremities; it is often accompanied by skin pain and sleep disruption with negative impacts on the quality of life (QoL). The patient-reported outcome (PRO) instruments, Worst Itch-Numeric Rating Scale (WI-NRS), Skin Pain-NRS, Sleep-NRS and Dermatology Life Quality Index (DLQI) have been psychometrically validated and the clinically meaningful within-patient improvement thresholds (responder definition) have been established through data pooled from the two Phase-3 trials (PRIME, NCT04183335 and PRIME2, NCT04202679) of dupilumab in adults with PN uncontrolled on topical therapies. OBJECTIVES: To estimate the proportion of dupilumab-treated patients (vs. placebo) achieving clinically meaningful improvement in itch, skin pain, sleep and QoL, either alone or in combination, from the data pooled from PRIME and PRIME2 trials. METHODS: The patient-level data pooled from the two Phase-3 trials (N = 311) were used for this post hoc analysis. Thresholds of clinically meaningful within-patient improvement in PRO instrument scores from baseline at Week 24 used for defining responders were 4 (WI-NRS and Skin Pain-NRS), 2 (Sleep-NRS) and 9 points (DLQI). The proportion of dupilumab-treated patients, versus placebo, achieving the thresholds, and the time taken to achieve the thresholds were evaluated for the individual and combination of PROs. RESULTS: Responder rates were significantly higher with dupilumab, versus placebo at Week 24 for WI-NRS (58.8% vs. 19.0%, p < 0.0001), Skin Pain-NRS (49.7% vs. 20.9%, p < 0.0001), Sleep-NRS (42.5% vs. 23.4%, p < 0.0001) and DLQI (64.7% vs. 22.8%, p < 0.0001). Proportion of patients achieving simultaneous improvement in symptoms and QoL (24.8% vs. 6.3%, p < 0.0001) were significantly higher in dupilumab-treated patients versus placebo. The time needed for achieving clinically meaningful improvement in symptoms were significantly lower in dupilumab-treated patients, versus placebo. CONCLUSIONS: Significantly greater proportion of dupilumab-treated patients with PN, versus placebo, demonstrated clinically meaningful improvements in PRO measures of symptoms and QoL.

Dupilumab leads to better-controlled asthma and quality of life in children: the VOYAGE study.

BACKGROUND: Dupilumab has shown long-term treatment benefits in children with uncontrolled asthma. We assessed in more detail the impact of dupilumab on asthma control and health-related quality of life (HRQoL) in children and their caregivers. METHODS: Children aged 6-11 years with uncontrolled moderate-to-severe type 2 asthma (baseline blood eosinophils ≥150 cells·µL-1 or fractional exhaled nitric oxide ≥20 ppb; n=350) were treated with dupilumab or placebo for 52 weeks in the VOYAGE study. Primary outcomes of these analyses were asthma control (change from baseline in Asthma Control Questionnaire 7 Interviewer-Administered (ACQ-7-IA) and achieving a clinically meaningful response of ≥0.5 points); proportion of patients achieving well-controlled asthma or better (ACQ-7-IA ≤0.75 points); effect on patients' (Standardised Paediatric Asthma Quality of Life Questionnaire Interviewer-Administered (PAQLQ(S)-IA)) and caregivers' (Paediatric Asthma Caregiver's Quality of Life Questionnaire (PACQLQ)) HRQoL; and allergic rhinitis-related QoL. RESULTS: Dupilumab versus placebo significantly improved children's ACQ-7-IA scores by week 4 with sustained improvements through week 52 (least squares mean difference at week 52: -0.44, 95% CI -0.59- -0.30; p<0.0001); a higher proportion achieved a clinically meaningful response (week 52: 86% versus 75%; p=0.0051). At weeks 24 and 52, more children who received dupilumab achieved well-controlled asthma (ACQ-7-IA ≤0.75 points: 61% versus 43%; p=0.0001 and 70% versus 46%; p<0.0001, respectively). Significant improvements in PAQLQ(S)-IA and PACQLQ scores were observed by week 52. CONCLUSIONS: In children aged 6-11 years with moderate-to-severe type 2 asthma, dupilumab treatment was associated with rapid, sustained improvements in asthma control. HRQoL was significantly improved for children and their caregivers.

Dupilumab efficacy and safety in Latin American patients with uncontrolled, moderate-to-severe asthma: phase 3 LIBERTY ASTHMA QUEST study.

OBJECTIVE: While advances in asthma care have been made in Latin America, there is still a large unmet need in patients with uncontrolled asthma. This post hoc analysis of the QUEST study assessed safety and efficacy of dupilumab in the subgroup of patients enrolled in Latin American countries with a type 2 inflammatory asthma phenotype (blood eosinophils ≥ 150cells/µL or FeNO ≥25ppb). METHODS: LIBERTY ASTHMA QUEST (NCT02414854) was a phase 3, multinational, randomized, double-blind, placebo-controlled study in patients with uncontrolled, moderate-to-severe asthma. Eligible patients ≥ 12 years of age were randomized in a 2:2:1:1 ratio to receive 52 weeks of add-on subcutaneous dupilumab 200 or 300 mg every 2 weeks or matched-volume placebos. Pre-specified co-primary efficacy endpoints were the annualized rate of severe exacerbations during the treatment period and the change from baseline in pre-bronchodilator FEV1 at treatment week 12. Asthma control, changes in asthma biomarker levels, and dupilumab safety were also evaluated. RESULTS: 530 (27.9% of the overall QUEST population; dupilumab: 353, placebo: 177) Latin-American patients were recruited; 420 (79.2%) had a type 2 inflammatory asthma phenotype. Dupilumab vs placebo reduced the annualized rate of severe exacerbations by 52.7% (P < 0.001) and increased pre-bronchodilator FEV1 at week 12 by 0.15 L (P < 0.001), in the type 2 population. Safety was consistent with the known dupilumab safety profile. CONCLUSIONS: Consistent with the results in the overall population, dupilumab reduced the risk of severe asthma exacerbations and improved lung function in Latin American patients with uncontrolled, moderate-to-severe asthma and a type 2 phenotype.

Efficacy of dupilumab in patients with uncontrolled, moderate-to-severe asthma recruited from Japanese centers in the phase 3 LIBERTY ASTHMA TRAVERSE study.

BACKGROUND: Safety and efficacy data for dupilumab beyond 1 year are lacking for patients from Japan with moderate-to-severe asthma. METHODS: The TRAVERSE open-label extension (OLE) study (NCT02134028) assessed the safety and efficacy of dupilumab 300 mg every 2 weeks up to 96 weeks in 2282 patients who completed a previous dupilumab asthma study. The primary endpoint was incidence of treatment-emergent adverse events (TEAEs). Secondary endpoints included annualized severe exacerbation rate and change from parent study baseline in pre-bronchodilator forced expiratory volume in 1 second (FEV1), asthma control, quality of life, and blood eosinophil levels. Anti-drug antibodies (ADA) were evaluated. We report results in 160 (7.8% of exposed population) patients recruited from Japanese centers with non-oral corticosteroid (OCS)-dependent asthma rolled over from two parent studies, and in subgroups with a type 2 inflammatory phenotype. RESULTS: TEAEs were consistent with the parent studies and the known safety profile of dupilumab. One patient permanently discontinued treatment due to TEAEs. Exacerbation rates remained low and were sustained to Week 96, as were improvements in pre-bronchodilator FEV1. Rapid, sustained improvements were observed in dupilumab-treated patients who previously received placebo in a parent study, while further improvements in exacerbation rates, asthma control, and asthma-related quality of life were observed in those continuing dupilumab. Blood eosinophil levels decreased progressively while on treatment. Treatment-emergent ADA responses were highest in patients who had previously received placebo. Efficacy results were consistent in patients with a type 2 phenotype. CONCLUSIONS: Long-term dupilumab treatment was well tolerated and efficacious in patients with non-OCS-dependent, moderate-to-severe asthma recruited from Japan.

Dupilumab improves health related quality of life: Results from the phase 3 SINUS studies.

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a predominantly type 2-mediated inflammatory disease with high symptom burden and reduced health-related quality of life (HRQoL). This report aimed to comprehensively understand the effects of dupilumab on domains of HRQoL, their individual elements, and health status in patients with severe CRSwNP from phase 3 SINUS-24 (NCT02912468) and SINUS-52 (NCT02898454) trials. METHODS: Patients were randomized to dupilumab (n = 438) or placebo (n = 286) for 24 weeks (SINUS-24), or 52 weeks (SINUS-52). Disease-specific HRQoL using 22-item sino-nasal outcome test (SNOT-22), and health status using EuroQoL-visual analog scale (EQ-VAS) was evaluated in the pooled intention-to-treat (ITT) population (Week 24), SINUS-52 ITT (Week 52) and in the subgroups with/without asthma; non-steroidal anti-inflammatory drug-exacerbated respiratory disease (NSAID-ERD); and prior sinus surgery. RESULTS: At baseline, patients had poor disease-specific HRQoL and general health status and identified "Decreased sense of smell/taste" and "Nasal blockage" as the most important symptoms. Dupilumab significantly improved SNOT-22 total, domain (Nasal, Sleep, Function, Emotion, and Ear/facial), and 22-item scores, and EQ-VAS, at Week 24 vs placebo (all p < .0001), with continued improvements to Week 52 in SINUS-52. Improvements occurred irrespective of comorbid asthma, NSAID-ERD, or prior surgery. A significantly greater proportion of dupilumab-treated patients exceeded clinically meaningful thresholds for SNOT-22 total score and EQ-VAS vs placebo (all subgroups p < .05 except patients without surgery at Week 24). CONCLUSIONS: Dupilumab treatment led to significant clinically meaningful improvements across all aspects of disease-specific HRQoL, and general health status in patients with severe CRSwNP.

How a concentration-effect analysis of data from the eliglustat thorough electrocardiographic study was used to support dosing recommendations.

Eliglustat is a first-line oral treatment for adults with Gaucher disease type 1 who have cytochrome P450 (CYP) 2D6 extensive, intermediate, or poor metabolizer phenotypes. Per International Conference on Harmonisation (ICH) E14 guidance, a Phase 1 thorough electrocardiographic (ECG) study was done during drug development to assess eliglustat's effects on cardiac repolarization by measuring ECG intervals in healthy adult subjects. Using data from the thorough ECG study, we performed pharmacokinetic/pharmacodynamic-ECG modeling to establish the relationship between eliglustat concentrations and their effects on ECG intervals. We then used that concentration-response relationship to predict the effects of eliglustat on each ECG interval for each CYP2D6 metabolizer phenotype (the main determinant of eliglustat exposure) and in different drug-drug interaction scenarios. These predictions, together with other exposure-related factors, contributed to the CYP2D6 phenotype-based dosing recommendations for eliglustat, including dose adjustments and contraindications when co-administered with drugs metabolized by the CYP2D6 and CYP3A pathways.

Model averaging inconcentration-QT analyses.

This article describes how a frequentist model averaging approach can be used for concentration-QT analyses in the context of thorough QTc studies. Based on simulations, we have concluded that starting from three candidate model families (linear, exponential, and Emax) the model averaging approach leads to treatment effect estimates that are quite robust with respect to the control of the type I error in nearly all simulated scenarios; in particular, with the model averaging approach, the type I error appears less sensitive to model misspecification than the widely used linear model. We noticed also few differences in terms of performance between the model averaging approach and the more classical model selection approach, but we believe that, despite both can be recommended in practice, the model averaging approach can be more appealing because of some deficiencies of model selection approach pointed out in the literature. We think that a model averaging or model selection approach should be systematically considered for conducting concentration-QT analyses. Copyright © 2016 John Wiley & Sons, Ltd.

Efficacy of avalglucosidase alfa on forced vital capacity percent predicted in treatment-naïve patients with late-onset Pompe disease: A pooled analysis of clinical trials.

Background: The efficacy of avalglucosidase alfa (AVA) versus alglucosidase alfa (ALG) on forced vital capacity percent predicted (FVCpp) in patients with late-onset Pompe disease (LOPD) has been assessed in the Phase 3 COMET trial (NCT02782741). Due to the rarity of LOPD and thus small sample size in COMET, additional data were analyzed to gain further insights into the efficacy of AVA versus ALG. Methods: Data from treatment-naive patients with LOPD were pooled from COMET and Phase 1/2 NEO1/NEO-EXT (NCT01898364/NCT02032524) trials for patients treated with AVA, and Phase 3 LOTS trial (NCT00158600) for patients treated with ALG. Regression analyses using mixed models with repeated measures consistent with those pre-specified in COMET were performed post-hoc. Analyses were adjusted for trials and differences in baseline characteristics. Four models were developed: Model 1 considered all trials; Model 2 included Phase 3 trials; Model 3 included Phase 3 trials and was adjusted for baseline ventilation use; Model 4 included COMET and NEO1/NEO-EXT (i.e., AVA trials only). Results: Overall, 100 randomized patients from COMET (AVA, n = 51, ALG, n = 49), 60 from LOTS (ALG arm only), and three patients from NEO1/NEO-EXT (who received open-label AVA only) were considered for analysis. Mean age at enrollment was similar across trials (45.3-50.3 years); however, patients from LOTS had a longer mean duration of disease versus COMET and NEO1/NEO-EXT trials (9.0 years and 0.5-2.2 years, respectively) and younger mean age at diagnosis (36.2 years and 44.7-48.6 years, respectively). Least squares mean (95% confidence interval) improvement from baseline in FVCpp at Week 49-52 for AVA versus ALG was 2.43 (-0.13; 4.99) for COMET (n = 98); 2.31 (0.06; 4.57) for Model 1 (n = 160); 2.43 (0.21; 4.65) for Model 2 (n = 157); 2.80 (0.54; 5.05) for Model 3 (n = 154); and 2.27 (-0.30; 4.45) for Model 4 (n = 101). Conclusions: Models 1 to 3, which had an increased sample size versus COMET, demonstrated a nominally significant effect on FVCpp favoring AVA versus ALG after 1 year of treatment, consistent with results from COMET.

Natural history of acid sphingomyelinase deficiency among European patients during childhood and adolescence: A retrospective observational study.

Acid sphingomyelinase deficiency (ASMD) is a rare, lysosomal storage disease with limited evidence on its natural history. This retrospective, medical record abstraction study aimed to characterize the natural history of ASMD (types B and A/B) during childhood and adolescence. Recruiting sites were European centers (i.e., France, Germany, Italy, and the United Kingdom) from the ASCEND-Peds trial (NCT02292654); these sites were targeted because of the rarity of ASMD and specialized care provided at these centers. The study population comprised ASMD trial patients (before exposure to treatment) and ASMD non-trial participants who were managed at the same trial sites. Overall, 18 patients were included (11 trials; 7 non-trials; median [Q1; Q3] age at ASMD diagnosis: 2.5 [1.0; 4.0] years). Median follow-up duration was 10.0 years. Frequently reported medical conditions were hepatobiliary (17 [94.4%]) and blood and lymphatic system disorders (16 [88.9%]). Adenoidectomy (3 [16.7%]) was the most commonly reported surgical procedure; gastroenteritis (5 [27.8%]) was the most frequently reported infection, and epistaxis (6 [33.3%]) was the most commonly reported bleeding event. Abnormal spleen (16 [88.9%]) and liver (15 [83.3%]) size and respiratory function (8 [44.4%]) were commonly reported during physical examination. Overall, 11 (61.1%) patients were hospitalized; 6 (33.3%) patients had emergency room visits. Findings were consistent with published literature and support the current understanding of natural history of ASMD.

Sustained improvements in patient-reported outcomes after long-term sutimlimab in patients with cold agglutinin disease: results from the CADENZA study open-label extension.

Background: Cold agglutinin disease (CAD) is a rare subtype of autoimmune haemolytic anaemia characterised by classical complement pathway-mediated haemolysis, fatigue, and poor quality of life (QoL). Sutimlimab, a C1s inhibitor, rapidly halted haemolysis, and improved patient-reported outcomes (PROs) in patients with CAD in two phase 3 trials (CARDINAL and CADENZA). Here we report PROs from the CADENZA open-label extension (Part B). Methods: The first patient was enrolled in CADENZA (NCT03347422) in March 2018 (Part A) and the last patient completed the study in December 2021 (Part B). All patients who completed the 26-week Part A were eligible to receive biweekly doses of sutimlimab in Part B for up to 1 year after the last patient completed Part A. PROs were assessed throughout Part B, until the last on-treatment visit with available assessment (LV), and after a 9-week washout. Findings: In total, 32/39 patients completed Part B; median Part B treatment duration: 99 weeks. Patients switching from placebo to sutimlimab in Part B experienced rapid improvement in Functional Assessment of Chronic Illness Therapy (FACIT)-Fatigue score and other PROs. Sustained, clinically important improvements in FACIT-Fatigue were observed throughout Part B in patients who switched to sutimlimab and those continuing sutimlimab treatment (combined-group mean [SE] change from baseline at LV: 8.8 [2.1]). Similarly, the combined-group mean [SE] change for 12-Item Short Form Health Survey physical (4.9 [1.7]) and mental (4.0 [1.8]) component scores exceeded clinically important changes from baseline at LV. EuroQol visual analogue scale showed consistent and sustained increases from baseline with sutimlimab treatment. Following a 9-week washout, all PROs approached baseline values. Interpretation: Continued inhibition of the classical complement pathway with sutimlimab results in meaningful long-term improvements in PROs (fatigue and QoL) in patients with CAD. Funding: Sanofi.

Worst Itch Numeric Rating Scale for Prurigo Nodularis: A Secondary Analysis of 2 Randomized Clinical Trials.

Importance: Prurigo nodularis (PN) is a debilitating skin disease characterized by the hallmark symptom of chronic itch; the intensity of itch in PN was assessed using the Worst Itch Numeric Rating Scale (WI-NRS) to evaluate the primary efficacy end point of 2 recent phase 3 studies of dupilumab treatment for PN. Objective: To validate the psychometric properties and to determine the clinically meaningful improvement threshold for WI-NRS in patients with moderate to severe PN. Design, Setting, and Participants: In this secondary analysis of the PRIME and PRIME2 trials, content validity of WI-NRS was assessed through in-depth patient interviews. Psychometric assessments used pooled data from masked, intention-to-treat (ITT) patients with PN from randomized, double-masked, and placebo-controlled studies. Psychometric assessments included test-retest reliability, construct validity, known-groups validity, and sensitivity to change in adult patients with moderate-to-severe PN. Thresholds for meaningful within-patient improvement in the WI-NRS score were determined using anchor and distribution-based approaches. Data were analyzed after completion of each study, December 2019 to November 2021 for PRIME and January 2020 to August 2021 for PRIME2. Exposures: Dupilumab (300 mg) or placebo subcutaneously every 2 weeks for 24 weeks. Main outcomes and measures: WI-NRS score at specified time points up to 24 weeks after randomization. Results: A total of 20 patients were included across the 2 studies (mean [SD] age, 49.3 [17.2] years; 11 female [55%]); 311 patients were included in the pooled intention-to-treat analysis (mean [SD] age, 49.5 [16.1] years; 203 female [65.3%]). The WI-NRS questions (20 of 20 patients), recall period (19 of 20 patients), and response scale (20 of 20 patients) were easy to understand and relevant for patients with PN. Adequate test-retest reliability was observed between screening and baseline (intraclass correlation coefficient = 0.72, using Patient Global Impression of Severity [PGIS] to define stable patients). Convergent and discriminant validity was supported by moderate to strong correlations (absolute r range = 0.34-0.73) with other conceptually related measures and weaker correlations (absolute r range = 0.06-0.32) with less-related measures, respectively. WI-NRS was sensitive to change, as demonstrated by differences in change from baseline among groups (per PGIS change and PGI of Change [PGIC]). Using anchor-based approach with PGIS and PGIC, the clinically meaningful improvement threshold was 4 points (range, 3.0-4.5), which was also supported by distribution-based methods. Conclusion and Relevance: This study found that WI-NRS may be a fit-for-purpose instrument to support efficacy end points measuring the intensity of itching in adults with PN. Trial Registration: NCT04183335 (PRIME) and NCT04202679 (PRIME2).

Impact of Dupilumab on Sinonasal Symptoms and Outcomes in Severe Chronic Rhinosinusitis With Nasal Polyps.

OBJECTIVES: To assess the severity of the top 5 22-item Sino-Nasal Outcome Test (SNOT-22) items ranked most important by patients with chronic rhinosinusitis with nasal polyps (CRSwNP), the effect of dupilumab on these items, and their association with objective disease measures. STUDY DESIGN: Post hoc analysis of the SINUS-24 (NCT02912468) and SINUS-52 (NCT02898454) clinical trials. SETTING: Multinational, multicenter, randomized, double-blind, placebo-controlled, parallel-group studies. METHODS: Patients ranked the SNOT-22 items most affecting their health at baseline. Item symptom severity (0-5 scale) was assessed at baseline, Week 24 (W24), and Week 52 (W52). Changes in nasal polyps score (NPS) and Lund-Mackay (LMK) scores were assessed in patients with/without SNOT-22 items improvements of at least 1 severity group point at W24 and W52. RESULTS: The SNOT-22 items ranked most important at baseline were "decreased sense of smell/taste" (87% of patients), followed by "nasal blockage" (82%), "postnasal discharge" (40%), "thick nasal discharge" (37%), and "wake up at night" (26%); 82%, 61%, 32%, 40%, and 26% of patients reported severe symptoms (score 4 or 5) for these items, respectively. Dupilumab improved score severity for all top 5 items versus placebo at W24 and W52. Improvements in NPS and LMK scores were numerically greater in patients with improvements in the SNOT-22 top 5 items. CONCLUSION: Loss of smell/taste was ranked as the most important symptom by patients with CRSwNP. Dupilumab reduced the severity of the top 5 most important SNOT-22 items versus placebo, in parallel with improvements in objective disease measures. CLINICAL TRIAL REGISTRATION: SINUS-24 and SINUS-52 clinical trials were registered with ClinicalTrials.gov, identifiers NCT02912468 and NCT02898454, respectively.

Dupilumab Efficacy in Patients With Uncontrolled or Oral Corticosteroid-Dependent Allergic and Nonallergic Asthma.

BACKGROUND: Type 2 cytokines IL-4/IL-5/IL-13 play an important role in pathogenesis of type 2 conditions, including asthma. Dupilumab, a human monoclonal antibody, blocks the shared receptor component for IL-4/IL-13, inhibiting signaling. In phase 2b (P2B) (NCT01854047) and phase 3 VENTURE (NCT02528214), dupilumab reduced annualized severe exacerbation rates (AER), improved forced expiratory volume in 1 second (FEV1), and was generally well tolerated in patients with uncontrolled, moderate-to-severe, or oral corticosteroid (OCS)-dependent severe asthma. OBJECTIVE: The post hoc assessment of dupilumab efficacy versus placebo in P2B and VENTURE in patients stratified by allergic status. METHODS: Allergic asthma was defined as total serum IgE ≥30 IU/mL and ≥1 perennial aeroallergen-specific IgE ≥0.35 kU/L at baseline. AER, prebronchodilator (BD) FEV1, FEV1/forced vital capacity (FVC) ratio, asthma control (5-item Asthma Control Questionnaire), health-related quality of life (HRQoL; Asthma Quality of Life Questionnaire), type 2 biomarkers, specific IgE, and OCS reduction (VENTURE only) were assessed. RESULTS: In patients with allergic asthma, dupilumab (P2B: pooled 200/300 mg; VENTURE: 300 mg) every 2 weeks versus placebo reduced AER (P2B: -60%, P < .01; VENTURE: -72%, P < .001), and, in P2B, increased pre-BD FEV1 (P < .01) and FEV1/FVC (P < .05). In both studies, dupilumab significantly improved asthma control and HRQoL and reduced most type 2 biomarkers. Dupilumab significantly reduced OCS use in VENTURE. Similar benefits were observed in patients without evidence of allergic asthma. CONCLUSIONS: Dupilumab significantly reduced AER and improved lung function, asthma control, and HRQoL in patients with or without evidence of allergic asthma.

Dupilumab provides early and durable improvement of symptoms in patients with chronic rhinosinusitis with nasal polyps.

Objectives: To evaluate within-patient symptom improvement in the dupilumab SINUS-24/-52 studies in patients with severe chronic rhinosinusitis with nasal polyps (CRSwNP) (NCT02912468/NCT02898454). Methods: Patients received dupilumab 300 mg or placebo every 2 weeks for 24 (SINUS-24) or 52 weeks (SINUS-52) on background intranasal corticosteroids. Patients daily reported symptoms of nasal congestion (NC), loss of smell (LoS) and rhinorrhoea on a scale of 0-3 (0 - no symptoms, 1 - mild, 2 - moderate, 3 - severe symptoms). The proportions of patients with moderate-to-severe symptoms (score ≥ 2) at baseline who improved to no-to-mild symptoms (score ≤ 1) were determined at Weeks 2, 24 (pooled studies) and 52 (SINUS-52). Subgroups with prior sinonasal surgery and coexisting asthma were analysed. Results: At baseline in the pooled intention-to-treat population (n = 724), the proportions of patients with scores ≥ 2 for NC, LoS and rhinorrhoea were 87, 94 and 64%, respectively. Significantly, more patients achieved scores ≤ 1 (no/mild symptoms) with dupilumab vs placebo for each symptom at each time point {Week 2 NC 12% vs 2% [odds ratio 8.9 (95% CI 3.0-26.3)], LoS 5% vs 1% [4.6 (1.3-16.8)], rhinorrhoea 9% vs 2% [4.8 (1.5-15.4)], all P < 0.05; Week 24 NC 54% vs 14% [8.7 (5.6-13.5)], LoS 43% vs 6% [14.4 (7.9-26.0)], rhinorrhoea 53% vs 16% [6.6 (4.1-10.9)], all P < 0.0001}. Results were similar in subgroups with prior surgery and coexisting asthma. Conclusion: Significantly, more patients achieved improvement from moderate-to-severe symptoms to no-to-mild symptoms with dupilumab than placebo, regardless of prior surgery or coexisting asthma. Improvement was observed as early as Week 2 and continued through to Week 52.

Dupilumab efficacy in high sleep disturbance management among patients with type 2 asthma.

BACKGROUND: Patients with asthma often experience sleep disturbances. We assessed the 5-item Asthma Control Questionnaire (ACQ-5) score ≥2.5 as a useful threshold to identify patients with moderate-to-severe type 2 asthma and high sleep disturbance (HSD) and investigated dupilumab efficacy on clinical and sleep-related outcomes among patients with HSD. METHODS: QUEST (NCT02414854) data were used in this post hoc analysis. A composite endpoint from validated patient-reported outcomes was developed to identify patients with HSD using sleep-related items from the ACQ-5, Asthma-Related Quality-of-Life Questionnaire, Rhino-Conjunctivitis Quality-of-Life Questionnaire, and Sino-Nasal Outcome Test-22. Impairment in at least 1 item was considered an indication of HSD. Change from baseline to Week 52 in nighttime symptoms, ACQ-5 score, lung function, annualized severe exacerbation rates (AER), and short-acting ß-agonists use during treatment was used to assess dupilumab efficacy. RESULTS: In type 2 asthma patients, 64% had HSD at baseline; of those with ACQ-5 ≥2.5 at baseline, 82% had HSD. In this population, dupilumab reduced nighttime symptoms and ACQ-5 score by 0.31 and 0.56 points, respectively, by Week 52 versus placebo, and led to a 66% reduction in AER during QUEST and 0.34 L improvement in pre-bronchodilator (pre-BD) forced expiratory volume in 1 s (FEV1) at Week 52. CONCLUSION: A majority of patients with moderate-to-severe type 2 asthma with ACQ-5 ≥2.5 at baseline had HSD. Dupilumab reduced nighttime symptoms and exacerbations, and improved lung function, overall asthma control, and quality of life. Further studies are needed to confirm the association between ACQ-5 score ≥2.5 and higher sleep disturbance rates.
