Cure8 research brief
Why This Matters
People on biologic therapy who lose response often face choices: switch drugs or increase dose. This study shows that escalating doses of infliximab, adalimumab, or vedolizumab frequently led to clinical improvement and moderate long-term persistence, information useful when discussing management options.
Who Should Pay Attention
Patients on infliximab, adalimumab, or vedolizumab who are experiencing loss of response; clinicians managing biologic dosing; researchers interested in real-world biologic outcomes.
Study Snapshot
What To Know
This retrospective cohort study (2018–2024) examined outcomes after dose escalation of infliximab, adalimumab, or vedolizumab for secondary loss of response in 155 people with IBD (mostly Crohn's). Escalation was often done for secondary loss of response and low drug concentrations.
Infliximab and adalimumab dose increases were associated with sustained improvements in clinical scores and some biomarker reductions; vedolizumab improvement was seen at 3 months only. Treatment persistence at 36 months ranged from ~58–73%. Nine patients had minor adverse events.
The report summarizes real-world, single-centre retrospective data rather than a randomized trial. It supports that dose escalation can regain clinical response for many patients and that persistence varies by agent. Discussing escalation alongside drug-level testing appears relevant, but individual decisions should be made with a clinician.

Keep In Mind
This is a retrospective single-centre cohort using data from 2018–2024; results may reflect local practice patterns and are not randomized evidence. ‘Dose escalation’ and reasons (secondary loss of response, low drug levels) were common but the study design limits causal conclusions.
