About this study

This is a pilot study with the primary purpose to describe organ dosimetry and acute toxicities using no carrier added and carrier added 124I-MIBG PET/CT in patients with neuroblastoma (NB). Eligible patients are 3 years of age and older with relapsed or refractory neuroblastoma who are currently enrolled on a treatment protocol with 131I-MIBG. After all eligibility criteria are met, patients will receive a diagnostic imaging dose of 124I-MIBG followed by sequential PET/CT dosimetry scans on Days 0, 1, 2 and 5. Subsequent, planned therapeutic administration of 131I-MIBG will occur between Days 7 to 21, as specified by the patient's therapeutic MIBG protocol. An optional single follow up 124I-MIBG PET-CT scan will be done to assess tumor sites 6 weeks after the patient has their MIBG therapy.

Read the detailed description

Accurate radiation dose evaluation is important in patients with malignant tumors, and this is especially critical in children with NB who will be receiving several dose of therapeutic 131I. The accurate quantification of the isotope-labeled analog can only be achieved by using positron emission compounds, such as 124I. Unlike planar images, which were used to obtain kinetic information, and SPECT reconstruction modalities that were aimed to assess the spatial distribution of radioactivity, 3D PET imaging-based dosimetry is a method which provides a more accurate estimation of the cumulated radioactivity distribution. Because PET provides better quantitative accuracy, when compared to SPECT regarding the tissue absorbed information, we hypothesize PET would better correspond with tumor response and normal organ toxicity. Early studies using I-124 for dosimetry in thyroid cancer have been promising.

Demonstration of the feasibility and accuracy of this new imaging modality, with the excellent prospect for more accurate dosimetry, will improve tumor localization and optimize therapeutic dosing with 131I-MIBG. The results of our work may potentially have also implications in the study of other neuroendocrine tumors. The Section of Nuclear Medicine and the Laboratory of Functional Imaging at the University of California, San Francisco, are equipped with state of the art instruments and is run by a highly skilled staff which will guarantee the success of the proposed research.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 124I-Metaiodobenzylguanidine (MIBG) (no-carrier added)Drug

    Also called 124I MIBG, MIBG

    124I-MIBG (no-carrier added) Administration (infusion, 1-2 minutes) followed by sequential PET/CT dosimetry scans on Days 0, 1, 2 and 5.

    Optional 124I-MIBG (no-carrier added) Administration \& PET/CT scan 6 weeks later.

  • 124I-MIBG (carrier added)Drug

    Also called 124I MIBG, MIBG

    124I-MIBG (carrier added) Administration (infusion, 60 minutes) followed by sequential PET/CT dosimetry scans on Days 0, 1, 2 and 5.

    Optional 124I-MIBG (carrier added) Administration \& PET/CT scan 6 weeks later.

  • Positron Emission Tomography (PET) /Computerized tomography (CT)Procedure or surgery

    Also called PET/CT

    A PET scan measures important body functions, such as metabolism. CT imaging uses special x-ray equipment, and in some cases a contrast material, to produce multiple images of the inside of the body. Combined PET/CT scans combine the processes of both a PET and CT at the same time.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Measurements of organ dosimetry using high specific activity (no carrier added)

    Descriptive statistics for each organ dose obtained from the organ dosimetry data will be reported, to demonstrate organ dosimetry calculations are feasible and concordant with prior calculations in prior conjugate planar dosimetry imaging studies and our pre-clinical murine models

    Measured: Up to 7 weeks

  2. Measurements of organ dosimetry using low specific activity (carrier added)

    Descriptive statistics for each organ dose obtained from the organ dosimetry data will be reported, to demonstrate organ dosimetry calculations are feasible and concordant with prior calculations in prior conjugate planar dosimetry imaging studies and our pre-clinical murine models

    Measured: Up to 7 weeks

  3. Number of participants with grade 3 or 4 imaging-related toxicities.

    All patients will have toxicity monitoring for 6 weeks following 124I-MIBG administration. Toxicities will be graded according to the NCI Common Toxicity Criteria for Adverse Events (CTCAEv4.0)and attribution assigned.

    Measured: Up to 7 weeks

  4. Change from baseline of blood pressure

    Blood pressure will be recorded before, during, end injection and post-injection at baseline, days 1, 2 and 5 and again at week 7 if participants choose to have optional week 7 scan

    Measured: Up to 7 weeks

  5. Change from baseline of pulse measurements

    Participants pulse will be recorded before, during, end injection and post-injection at baseline, days 1, 2 and 5 and again at week 7 if participants choose to have optional week 7 scan

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 14 May 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Funding). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Measurements of organ dosimetry using high specific activity (no carrier added) (time frame: Up to 7 weeks). The study lists 5 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 May 2021.
