Real-world quality of life in patients with hereditary angioedema receiving lanadelumab or other long-term prophylaxis
Background:
Hereditary angioedema (HAE) is a rare, potentially fatal genetic disorder characterized by unpredictable attacks of bodily swelling that substantially impair patients’ quality of life (QoL). Lanadelumab is approved for long-term prophylaxis (LTP) in patients with HAE; however, there are limited real-world data that compare lanadelumab with other treatments to guide patient care.
Objective:
The objective was to describe real-world QoL and related outcomes of patients with HAE who received lanadelumab versus other LTP.
Methods:
Data were drawn from a real-world, cross-sectional survey of physicians and their consulting patients with HAE in the United States from January 2023 to January 2024. Physician-reported attack and disease severity, pain, fatigue, QoL, and patient-reported outcomes were compared among patients receiving lanadelumab or other LTP.
Results:
Physicians reported data on 86 patients treated with lanadelumab and 84 treated with other LTP. A statistically significantly higher proportion of patients receiving lanadelumab had no chronic pain (58.1%) and no chronic fatigue (51.2%) at the time of the survey than those receiving other LTP (38.1% [p = 0.0023] and 34.9% [p = 0.0037], respectively). More patients receiving lanadelumab had “very good” physician-reported QoL and less patient-reported QoL impairment at the time of the survey compared with those receiving other LTP (p = 0.0102). A higher proportion of patients receiving lanadelumab compared with other LTP reported complete satisfaction overall with their treatment (30.2% versus 17.9%, respectively; p = 0.0144) and complete satisfaction with the efficacy of their treatment (44.2% versus 11.9%, respectively; p < 0.0001).
Conclusion:
In this real-world study, physicians reported a higher proportion of patients receiving lanadelumab had no chronic pain or fatigue compared with those receiving other LTP. Both physicians and patients reported higher QoL in those receiving lanadelumab. Continued real-world research in patients with HAE to further assess the effect of lanadelumab on QoL will help guide patient care.

- Allergy and Asthma Proceedings is a peer reviewed publication dedicated to distributing timely scientific research regarding advancements in the knowledge and practice of allergy, asthma and immunology. Its primary readership consists of allergists and pulmonologists.
The goal of the Proceedings is to publish articles with a predominantly clinical focus which directly impact quality of care for patients with allergic disease and asthma and by having the potential to directly impact the quality of patient care. AAP welcomes the submission of original works including peer-reviewed original research and clinical trial results. Additionally, as the official journal of the Eastern Allergy Conference (EAC), AAP will publish content from EAC poster sessions as well as review articles derived from EAC lectures.
Featured topics include asthma, rhinitis, sinusitis, food allergies, allergic skin diseases, diagnostic techniques, allergens, and treatment modalities. Published material includes peer-reviewed original research, clinical trials and review articles.
Articles marked "F" offer free full text for personal noncommercial use only.
