Changes in inflammatory bowel disease patients' perspectives on biosimilars: A follow-up survey.

BACKGROUND AND AIMS

The aim of this survey was to find out whether the perspectives of patients with inflammatory bowel disease concerning biosimilars have changed since the publication of our last survey carried out in 2014-2015.

METHODS

An online survey consisting of 19 questions was made available by the European Federation of Crohn's and Ulcerative Colitis Associations between July 2018 and December 2018. Only respondents who had heard of biosimilars were asked to respond to all of the questions.

RESULTS

In total, 1619 patients with inflammatory bowel disease responded the questionnaire. Most respondents were from Europe (79%), followed by Asia (8%), South America (7%) and Africa (5%). Some 44% of them had heard of biosimilars, and only these respondents continued to the biosimilar-specific questions. Respondents worried significantly more about biosimilars being less effective than the originator (50% in current and 39% in previous survey,  = 0.0004). However, respondents were more likely to believe that biosimilars will have an impact on the management of inflammatory bowel disease (75% in current and 62% in previous survey).

CONCLUSIONS

Many patients with inflammatory bowel disease remain unfamiliar with biosimilars. Although patients still worry about different aspects regarding biosimilars, they also tend to be more confident that biosimilars will have an impact on the management of their disease. More patient education is still needed to raise awareness about biosimilars.
