Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The purpose of this study is to evaluate the utilization of health resources in a testing based strategy versus an empiric dose escalation strategy to manage Crohn's disease and Ulcerative Colitis in subjects with loss of response to infliximab or adalimumab.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

Enrollment (Actual)

Enrollment

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  • Males 18 years of age or older who are not receiving azathioprine or 6 mercaptopurine.
  • Non-pregnant, non-lactating females, 18 years of age or older.
  • Females of child bearing potential must have a negative serum pregnancy test prior to randomization, and must use a hormonal (oral, implantable or injectable) or barrier method of birth control throughout the study. [defined as a minimum of one year since the last menstrual period]).
  • Documented diagnosis of CD or UC.
  • Active disease symptoms at visit 1 defined by: a. CD subjects: HBS ~ 6 UC subjects: PMCS ~ 4.
  • Current infliximab therapy (naive to adalimumab) or current adalimumab therapy (naive to infliximab ).
  • A minimum of 13 weeks of infliximab or adalimumab treatment prior to visit 1 at the following dose:
  • Stable dose of azathioprine, 6 mercaptopurine, methotrexate, and/or 5-aminosalicylates in the 4 weeks prior to visit 1.

Exclusion Criteria:

  • Contraindication to the use of either infliximab or adalimumab.
  • Current infliximab treatment but not naive to adalimumab or
  • Current adalimumab treatment but not naive to infliximab.
  • Infliximab dosing prior to visit 1 was not 5 mg/kg at weeks 0, 2 and 6 and then q8w.
  • Adalimumab dosing prior to visit 1 was not 160 mg at week 0, 80 mg at week 2, and then 40 mg q2w.
  • Received any investigational drug within 30 days prior to visit 1.
  • Serious underlying disease other than CD or UC which in the opinion of the investigator may interfere with the subject's ability to participate fully in the study.
  • History of alcohol or drug abuse which in the opinion of the investigator may interfere with the subject's ability to comply with the study procedures.
  • Stools positive for clostridium difficile.
  • Pregnant or lactating women.
  • Change in dose of azathioprine, 6 mercaptopurine, methotrexate, and/or 5-aminosalicylates in the 4 weeks prior to visit 1.
  • Males 22 years of age or less who are receiving azathioprine or 6 mercaptopurine.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Empiric Dose Intensification

Other: Intensify treatment with the existing drug
Intensify treatment with the existing drug and if this fails empirically switch to another TNF antagonist
Active Comparator: Testing based strategy
Measurement of drug (Adalimumab/Infliximab) Testing-based strategy for the management of secondary loss of response that is based on drug/ ADA measurement
Other: Measurement of drug (Adalimumab/Infliximab)

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
the mean difference in cumulative costs (Visit I to Week 3 1) between the two treatment arms
Time Frame: 31 weeks
Analysis of costs and outcomes will be made on an intention-to-treat basis
31 weeks

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.
Outcome Measure
Measure Description
Time Frame
The efficacy of the testing-based strategy compared to empiric dose intensification
Time Frame: 31 weeks
The proportion of subjects achieving clinical remission
31 weeks
