OBT Measurement to Differentiate Between Presence and Absence of HCC Determined by MRI

April 9, 2015 updated by: Yongping Yang, Beijing 302 Hospital

Evaluation of the Capability of the ¹³C-Octanoate Breath Test (OBT) Measurement to Differentiate Between Presence and Absence of HCC Determined by MRI in Patients With Chronic Liver Disease

The Exalenz clinical investigation is a multicenter, non-randomized, study of the ¹³C-Octanoate Breath Test (OBT). The present study is a feasibility trial, which aims to evaluate the capability of the OBT to differentiate between presence and absence of HCC determined by Magnetic Resonance Imaging (MRI) in patients with chronic liver disease.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

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

  1. Informed consent will be obtained from all patients prior to enrollment.
  2. The trial will be conducted in compliance with this protocol, with GCP standards, and the applicable regulatory requirements.
  3. This study will be cross-sectional, where patients will be enrolled on a walk in basis. Once one arm is completed the other one will be enriched in order to obtain at least 50 positive and at least 50 negative HCC subjects as defined by MRI.
  4. All patients will undergo AFP and US if they do not have results within the past three months.
  5. If the patient undergoes liver FNA, the biopsy results will be evaluated for the presence of HCC.
  6. For all patients, a case report form will be completed.
  7. All patients will undergo a physical examination, and their medical history/concomitant medications, weight, height and age will be recorded. Furthermore, recent (past 3 months) blood test results, if available, may be recorded.
  8. If relevant (woman of child bearing age), a pregnancy test will be performed to rule out pregnancy when performing the breath test.
  9. All MRI negative patients with low OBT results will undergo additional MRI within 6 to 12 months post OBT to rule out HCC occurrence.
  10. If available, all additional MRI/CT/US results will be recorded within the patient's CRF.

Study Contact

The name and contact information for the person who can answer enrollment questions for a clinical study. Each location where the study is being conducted may also have a specific contact, who may be better able to answer those questions.

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

All

Sampling Method

Non-Probability Sample

Study Population

The proposed study will include subjects with chronic liver disease of any cause at risk for HCC with MRI results within 3 months prior to OBT or scheduled for MRI within the time frame of the study, and who meet the inclusion criteria and none of the exclusion criteria.

Description

Inclusion Criteria:

  1. Any patients with chronic liver disease at risk for HCC.
  2. Age ≥ 18 years.
  3. Patient has an MRI result (positive or negative for HCC) up to 3 months prior to recruitment or will be scheduled for an MRI during the trial period.
  4. Patient is naïve to HCC treatment (RFA or TACE or Oral HCC treatments) since last MRI.

Exclusion Criteria:

  1. Any patients with chronic liver disease at risk for HCC.
  2. Age ≥ 18 years.
  3. Patient has an MRI result (positive or negative for HCC) up to 3 months prior to recruitment or will be scheduled for an MRI during the trial period.
  4. Patient is naïve to HCC treatment (RFA or TACE or Oral HCC treatments) since last MRI.
  5. Patients currently receiving total parenteral nutrition if they have contraindications to oral drugs.
  6. Women who are pregnant or breast feeding.
  7. Patient taking drugs that can interfere with octanoate metabolism or can also cause NAFLD independent of the metabolic syndrome, including: corticosteroids, amiodarone, tetracycline, valproic acid, methotrexate, stavudine, zidovudine.
  8. Patient, based on the opinion of the investigator, should not be enrolled into this study.
  9. Patient unable or unwilling to sign informed consent.
  10. Patients that are participating in other clinical trials evaluating experimental treatments or procedures

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
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.
HCC positive
¹³C-Octanoate Breath Test in 50 MRI proven HCC positive patients
Device: ¹³C-Octanoate Breath Test
Breath testing utilizing 13C is a safe, non-invasive means for measuring a certain pathway's metabolic rate. 13C is a stable, non-radioactive isotope which can be incorporated into a specific location within a test substrate so it would be released when the compound is metabolized by the liver. Hepatic metabolism of the compound is assessed by measuring the ratio of 13CO2/12CO2 in exhaled breath.
HCC negative
¹³C-Octanoate Breath Test in 50 MRI proven HCC negative patients
Device: ¹³C-Octanoate Breath Test
Breath testing utilizing 13C is a safe, non-invasive means for measuring a certain pathway's metabolic rate. 13C is a stable, non-radioactive isotope which can be incorporated into a specific location within a test substrate so it would be released when the compound is metabolized by the liver.
