Trial Outcomes & Findings for Safety of Reduced Infliximab Infusion Time (NCT NCT05340764)

NCT ID: NCT05340764

Last Updated: 2024-08-29

Results Overview

Acute infusion reaction is defined as any reaction occurring during or within 1 hour after completion of the infusion. It will be separated into mild reactions and moderate/severe reactions as outlined below. Mild/Localized Reaction Pruritus Flushing (facial erythema) Rash/Urticaria Rigors Swelling Moderate/Severe Reaction Fever (temperature \> 38.3 degree Celsius) Heart Rate greater than 120 Dyspnea/Shortness of breath Decrease in consciousness Hypotension defined as decrease in baseline SBP by \>20 mmHg or SBP \<85 Bronchospasm or laryngospasm Anaphylactic shock of one hour, to the standard two-hour infusion.

Participant Flow

Participants were recruited from 2020 to 2021 and followed throughout the study after enrollment. Patients aged 18 years or older with an established diagnosis of IBD, receiving infliximab at one of our infusions centers and have tolerated the 3 induction doses and current maintenance dosing were eligible for inclusion in the study.

Patients were excluded if they were receiving infliximab exclusively for a non-IBD indication, had a history of moderate or severe infusion reactions to infliximab (or biosimilar), had known antidrug antibodies to infliximab, had an interval greater than 13 weeks from prior dose of infliximab, were receiving an additional infusion concomitant with infliximab (eg, IV iron), or declined to participate in the trial.
