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

[18F]FSPG PET/CT imaging will noninvasively assess system xc- of cancer and inflammation. Diagnostic validity of [18F]FSPG for assessing disease activity will be assessed in subjects with inflammatory bowel disease.

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

19 years to 79 years (Adult, Older Adult)

Accepts Healthy Volunteers

Description

Inclusion Criteria:

  • Subject is aged between 19 and 79 years and male or female of any race/ethnicity.
  • Subject has had ulcerative colitis or Crohn's disease diagnosed by clinical, endoscopic and histologic evidence at least 3 months prior to screening.
  • Subject has symptoms suggestive of active disease at the time of enrollment.
  • Subject is scheduled to undergo sigmoidoscopy or colonoscopy for ulcerative colitis or Crohn's disease within 7 days prior to or after the planned study with [18F]FSPG administration.

Exclusion Criteria:

  • Subject or subject's legally acceptable representative does not provide written informed consent.
  • Subject displays clinical signs of ischemic colitis or has an evidence of pathogenic bowel infection.
  • Subject is diagnosed as having inflammatory bowel disease unclassified.
  • Subject has been treated with sulfasalazine or intravenous corticosteroids within the previous four weeks prior to the planned study with [18F]FSPG administration.
  • Dose escalation of the current inflammatory bowel disease drugs or starting a new oral aminosalicylate, corticosteroid, immunomodulator, biologics, antibiotics, probiotics, or topical preparations is scheduled from the study enrollment to the scheduled sigmoidoscopy or colonoscopy, or 24 hours after [18F]FSPG administration . The dose escalation or starting a new antidiarrheal and/or analgesic drug is allowed.
  • Female subject is pregnant or nursing. Exclusion of the possibility of pregnancy is made by one of the following: 1) Woman is physiologically post-menopausal (cessation of menses for more than 2 years), 2) woman is surgically sterile (has had a documented bilateral oophorectomy and/or documented hysterectomy, or 3) if the woman is of childbearing potential, a serum or urine pregnancy test performed within 24 hours immediately prior to administration of [18F]FSPG has to be negative and the women is advised to apply contraceptive measures during her participation in this study.
  • Subject has concurrent severe and/or uncontrolled and/or unstable medical disease (e.g. congestive heart failure, acute myocardial infarction, severe pulmonary disease, chronic renal or hepatic disease which could compromise participation in the study) in the judgment of the investigator.
  • Subject is a relative of the investigator, student of the investigator or otherwise dependent.
  • Subject has received any investigational drugs or devices within four weeks prior to the study enrollment.
  • Subject has been previously included in this study.
  • Subject has any other condition or personal circumstances that, in the judgment of the investigator, might make collection of complete data difficult or impossible.
  • Subject is allergic to hyoscine or any of ingredients of hyoscine butylbromide, or has myasthenia gravis, megacolon, closed angle glaucoma, or obstructive prostatic hypertrophy.

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
Sensitivity and specificity of active disease
Time Frame: 60 - 75 min
Sensitivity and specificity of [18F]FSPG PET/CT for the diagnosis of subjects with endoscopic evidence of active disease
60 - 75 min
Sensitivity and specificity of severe disease (presence of ulceration)
Time Frame: 60 - 75 min
Sensitivity and specificity of [18F]FSPG PET/CT for the diagnosis of subjects with endoscopic evidence of severe disease (presence of ulceration)
60 - 75 min

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
Area under the receiver operating characteristic curve of active disease
Time Frame: 60 - 75 min
Area under the receiver operating characteristic curve, sensitivity and specificity of segmental [18F]FSPG PET/CT assessment for detecting bowel segments with endoscopic evidence of active disease
