Correlation of Infliximab Levels With Outcomes in Ulcerative Colitis

April 7, 2022 updated by: Darrell S. Pardi, M.D., Mayo Clinic
To assess if infliximab drug levels in subjects with Ulcerative Colitis predict risk of colectomy rate. Additionally, the investigators will estimate an optimal day 4 infliximab level based on the study results.

Detailed Description

Infliximab is approved for induction and maintenance of clinical remission and mucosal healing in patients with moderate to severe active ulcerative colitis, in those who have an inadequate response to conventional therapy such as IV steroids. It is typically dosed at 5 mg/kg at 0, 2, and 6 weeks, followed by 5 mg/kg every 8 weeks thereafter. The alternative to rescue medical therapy with infliximab is proctocolectomy with ileal pouch anastomosis, which carries risks including pouchitis, fecal incontinence, pouch failure requiring further surgical procedures and female infertility, or proctocolectomy with permanent end-ileostomy, which many patients wish to avoid. The induction regimen of 3 doses of Infliximab followed by a maintenance dose every 8 weeks is used to achieve response in hopes of avoiding colectomy. Unfortunately, a large proportion of patients are unable to achieve or sustain a clinical response over time and end up getting a colectomy.

Potential implicated pathways in non-responders include fecal wasting of infliximab and factors that accelerate drug clearance such as a large TNF (tumor necrosis factor) or CRP (C reactive protein) burden, anti-infliximab antibodies (ATI), low serum albumin, male sex and larger body size. Patients with severe ulcerative colitis who fail corticosteroids and standard dosing with infliximab usually proceed to proctocolectomy. Optimizing early infliximab blood levels in patients with moderate-severe ulcerative colitis by administering the second dose of infliximab before week 2 could improve the efficacy and further reduce the need for colectomy. However, there is a paucity in the literature as this is a relatively new school of thought. Our study will address this deficit by evaluating the relationship between early drug levels of infliximab in ulcerative colitis and colectomy rates at one and three months.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

Patients must be scheduled to receive clinically indicated infliximab at the discretion of their treating physician during an acute hospitalization with a flare of moderate to severe UC. These will be inpatients at Mayo Clinic Rochester campus or be admitted in Mayo Clinic Health Systems. Endoscopic findings will be noted and those deemed to have moderate to severe disease activity based on the Mayo Scoring System for Assessment of Ulcerative Colitis Activity will be considered.

Description

Inclusion Criteria

  1. Adults, ages 18-65 years
  2. Hospitalized, with a moderate -severe flare. Based on the Mayo Scoring System for Assessment of Ulcerative Colitis Activity (Mayo score of equal or greater than 6)
  3. Treatment naïve to anti TNF agents
  4. Initiation of infliximab, with or without immunomodulator such as azathioprine
  5. Ongoing use of immunomodulators such as azathioprine or 6MP is acceptable. Their initiation or continuation remains at the discretion of the treating physician

Exclusion Criteria

  1. Ongoing or prior treatment with Infliximab or other anti TNF agents
  2. Ongoing or recent (with in 1 month) administration of rescue cyclosporine
  3. Fulminant colitis requiring emergent surgery or toxic megacolon
  4. Pregnancy
  5. Infectious colitis, for example Clostridium difficile or CMV (cytomegalovirus) colitis
  6. Active infection or abscess
  7. Untreated latent or active tuberculosis (TB). Those with latent TB who are currently undergoing treatment can be included. Please refer to appendix 1 for more information on specific inclusion and exclusion criteria related to TB testing. Refer to 1.4.2 of appendix 1 for TB screening questions
  8. Active malignancy
  9. Active or history of Congestive Heart failure (CHF) or those who have received treatment for CHF
  10. Active or history of Multiple Sclerosis (MS), or those who have received treatment for MS
  11. Prisoners, institutionalized individuals, and individuals who are not capable of giving informed consent
  12. Judgement of investigator

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants to be Colectomy Free at 3 Months
Time Frame: 3 month
Total number of participants to be colectomy free at 3 months
3 month
Number of Participants With the Need for Colectomy Assessed by Biomarker Levels
Time Frame: 3 months
Biomarkers markers ESR, CRP, TNF levels, and hemoglobin will be collected to assess relationships between colectomy an other potential biomarkers
3 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
