Patients with severe, uncontrolled asthma experience frequent exacerbations and hospitalization, leading to poor health-related quality of life. In the phase 2b PATHWAY study (NCT02054130), tezepelumab reduced exacerbations by up to 71% and improved lung function, asthma control, and health-related quality of life vs placebo.
This analysis further assessed the impact of tezepelumab on patient-reported outcomes (PROs) in PATHWAY.
Adults with severe, uncontrolled asthma were randomized to subcutaneous tezepelumab (70 mg every 4 weeks, 210 mg every 4 weeks, or 280 mg every 2 weeks) or placebo for 52 weeks. PROs were assessed using the asthma control questionnaire-6 (ACQ-6) and the asthma quality of life questionnaire (standardized) for patients aged 12 years or older (AQLQ[S]+12). The proportions of responders (defined by improvements of ≥0.5 in ACQ-6 or AQLQ(S)+12 scores) and patients whose asthma was well-controlled, partially-controlled, or uncontrolled in the tezepelumab and placebo groups were identified. The Asthma Daily Diary questionnaire was used to assess changes in overall symptom severity.
Overall, 550 patients were randomized. Up to 82% and 77% of tezepelumab-treated patients were ACQ-6 and AQLQ(S)+12 responders, respectively, compared with 70% and 64% of placebo-treated patients, respectively. The proportions of patients with well-controlled or partially-controlled asthma were higher in the tezepelumab-treated group than in the placebo group. In addition, tezepelumab improved the overall symptom severity.
Tezepelumab treatment improved PROs vs placebo, as indicated by the higher proportion of ACQ-6 and AQLQ(S)+12 responders and improvements in symptom severity in the tezepelumab dose groups. These data further support the benefits of tezepelumab in patients with severe, uncontrolled asthma.
严重、未控制的哮喘患者经常出现恶化和住院,导致健康相关生活质量较差。在 2b 期 PATHWAY 研究(NCT02054130)中,特泽单抗使恶化减少了高达 71%,并改善了肺功能、哮喘控制和健康相关生活质量,与安慰剂相比。
本分析进一步评估了特泽单抗对 PATHWAY 中患者报告结局(PRO)的影响。
患有严重、未控制的哮喘的成年人被随机分配接受皮下特泽单抗(70mg 每 4 周,210mg 每 4 周或 280mg 每 2 周)或安慰剂治疗 52 周。使用哮喘控制问卷-6(ACQ-6)和标准化的哮喘生活质量问卷(AQLQ[S]+12)评估 PROs。对于年龄在 12 岁或以上的患者(AQLQ[S]+12),定义为 ACQ-6 或 AQLQ[S]+12 评分改善≥0.5 的患者比例和特泽单抗和安慰剂组中哮喘控制良好、部分控制或未控制的患者比例。使用哮喘日常日记问卷评估整体症状严重程度的变化。
总体而言,550 名患者被随机分配。特泽单抗治疗组的 ACQ-6 和 AQLQ[S]+12 应答者比例分别达到 82%和 77%,而安慰剂治疗组分别为 70%和 64%。特泽单抗治疗组中哮喘控制良好或部分控制的患者比例高于安慰剂组。此外,特泽单抗改善了整体症状严重程度。
与安慰剂相比,特泽单抗治疗改善了 PROs,这表明 ACQ-6 和 AQLQ[S]+12 应答者的比例更高,特泽单抗剂量组的症状严重程度改善。这些数据进一步支持特泽单抗在严重、未控制的哮喘患者中的益处。
