Effectiveness and safety of switching to adalimumab biosimilar ABP 501 in Crohn's disease: the extrapolation concept.

ABSTRACT

We sincerely thank Viscido et al. for their appropriate and sharable comments on our recent study on adalimumab biosimilar ABP 501 in Crohn's disease (CD). The use of a biosimilar in inflammatory disorders is one of the current main topics, given the great opportunity to save resources that can be invested in innovative drugs and the ethical problems that non-medical switching can generate.
