摘要

Background

In the context of injectable biologic products approved or in development for chronic spontaneous urticaria (CSU), it is important to capture which treatment attributes matter most to patient and what trade-offs patients are willing to make.

Objectives

The CHOICE-CSU study aimed to quantify patient preferences toward injectable treatment attributes among patients with CSU, inadequately controlled by H1-antihistamines.

Methods

This was a two-phase cross-sectional patient preference study in adult patients with a diagnosis of CSU, inadequately controlled by H1-antihistamines. A qualitative phase collected patients’ insights and relevant treatment attributes that mattered to them, and the outputs were used for the quantitative phase to create the actual injectable treatment profiles with attributes and levels such as: efficacy, safety, and mode of administration. The quantitative phase used discrete choice experiment (DCE) methodology. Eligible patients were asked to make hypothetical choices between 12 treatment profile pairs, created by Sawtooth SoftwareTM. The DCE data were analyzed using hierarchical Bayesian logistic regression models, enabling the quantification of the relative importance of each attribute/level during the decision-making process.

Results

A total of 450 respondents participated in the DCE. The key attributes driving respondent preference amongst injectable treatment options were type of administration device (relative importance 18.5%), complete control of urticaria (relative importance 17.4%), and resolution of angioedema (relative importance 16.4%). Keeping all other attributes and levels equal, the predicted choice share was higher for a profile with an auto-injector versus one with a pre-filled syringe (72.9% versus 27.1%).

Conclusions

The CHOICE-CSU study is the first study to provide a quantitative assessment of preferences that patients with CSU, inadequately controlled by H1-antihistamines, have for injectable treatment attributes. Symptom-free periods are the most important overriding therapy goal for patients, and patients will accept some inconveniences, such as administration mode, to achieve this. Additionally, when efficacy is equivalent, administration ease of injectable therapies is valued by patients. As new CSU oral treatment options emerge, additional testing of patient preference toward oral treatments will be required.
