Safety of Reduced Infliximab Infusion Time

Phase 4

Completed

Conditions: Inflammatory Bowel Diseases

Interventions: Drug: Infliximab

Registration Number: NCT05340764

Lead Sponsor: Washington University School of Medicine

Brief Summary: Remicade is a common medicine used for the treatment of inflammatory bowel disease. This medication is given as an intravenous infusion over 2 hours. Studies have suggested it is safe to give the infusion at a faster rate. The investigators would like to see if the infusion can be given over 1 hour. The investigators expect that increasing the rate of infusion WILL NOT lead to an increase in infusion reactions and will be just as safe and effective as the standard 2 hours dose.

Detailed Description: 1.1 Infliximab use in IBD

Inflammatory bowel disease (IBD) affects 349 per 100,000 adults in the United States and is associated with significant morbidity and mortality. Infliximab is an effective and commonly used medication to treat patients with IBD, but a main safety concern is an antibody-induced infusion reaction. The incidence of infusion reactions is \~6.5%, with mild, moderate, or severe reactions occurring in 3.1%, 1.2%, and 1% of infusions, respectively. Because of the concern for infusions reactions, infliximab is FDA approved to be infused over 2 hours or more. The typical interval for infusions is every eight weeks but is at times reduced to every 4 weeks in patients with IBD. This infusion time represents a significant inconvenience to patients who receive regular maintenance infusions.

1.2 Accelerated Infliximab Infusions

Multiple studies outside of the United States have demonstrated that a shortened infusion time to one hour, and even thirty minutes is safe and tolerable with similar rates of infusion reactions compared to an infusion time of two hours. However, these studies have differed in dosing, interval, pre-medication allowed in the study, and they are not randomized controlled studies. It has also been shown that reducing infusion times leads to cost savings and increased patient satisfaction. A recent study conducted in the United States at the University of California in San Francisco, confirmed that a shortened infusion time of one hour is safe and tolerated.

1.3 Rationale

The hypothesis is that a shortened infusion time to one hour will be safe and tolerated, with equal infusion reaction rates compared to two-hour infusion

Patients with known antidrug antibodies to infliximab
Patients who are restarting infliximab (patients who have received infliximab within the past year but have now had an interval greater than 13 weeks between prior dose) must tolerate the three induction doses to qualify for randomization
Patients receiving an additional infusion concomitant with infliximab (e.g. IV iron)
Patients who decline to participate in the trial

Arm && Interventions

Group	Intervention	Description
2-hour infusion of infliximab	Infliximab	2 hour infusion of infliximab Infliximab: Infliximab is an effective and commonly used medication to treat patients with IBD. Patients in this group received the standard 2 hour infusion of infliximab and serves as the control group.
1-hour infusion of infliximab	Infliximab	1 hour infusion of infliximab Infliximab: Infliximab is an effective and commonly used medication to treat patients with IBD. Patients in this group received the reduced 1 hour infusion of infliximab and serves as the study group.

Primary Outcome Measures

Name	Time	Method
Number of Participants With Acute Infusion Reaction as Assessed by the Nursing Staff of the Infusion Unit	Median of 12 months in the control and a median of 14 months in the study group.	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.

Secondary Outcome Measures

Name	Time	Method
Number of Infusions Where Concomitant Immunomodulators and Pre-medications Were Used	Median of 12 months in the control and a median of 14 months in the study group.	Number of Infusions where Concomitant Immunomodulators and Pre-medications were used in the study
Effect of Concomitant Immunomodulators and Pre-medications on Rate of Infusion Reactions - Duration of Follow up (in Months)	Median of 12 months in the control and a median of 14 months in the study group.	Assess effect of concomitant immunomodulators and pre-medications on rate of infusion reactions - Duration of follow up (in months)
Effect of Concomitant Immunomodulators and Pre-medications on Rate of Infusion Reactions - Median Number of Infusions	Median of 12 months in the control and a median of 14 months in the study group.	Assess effect of concomitant immunomodulators and pre-medications on rate of infusion reactions - Median number of infusions
Cost Saving Analysis	Median of 12 months in the control and a median of 14 months in the study group.	Direct costs of the 2 hour infusion per-infusion per-patient in dollar amount will be compared to direct costs of the 1 hour infusion per-infusion per-patient in dollar amount in our institution and the difference will be reported.
