About this study

Official title: A Study of 18F-FLT Positron Emission Tomography (PET)/Computed Tomography Imaging in Pediatrics With Myeloproliferative Neoplasms

The Main purpose of this project to study the uptake pattern of FLT-PET and it is value in assessing the malignant hematopoiesis in MPN within the pediatric age group, in terms of diagnosis, staging and monitoring response to therapy. As well as, evaluating FLT-PET as a novel non-invasive technique in cases with MPN and its role in comparison to the standard bone marrow biopsy with regard to disease diagnosis, assessment of disease activity, detection of transformation, monitoring of treatment response and grading of fibrosis.Furthermore, we aim to study the association of FLT-PET uptake patterns with different genetic makeup (JAK2, CALR positive, MPL, or Triple negative disease) or allele burden in cases of Pre-PMF with the ability of FLT-PET to differentiate between Pre-PMF and ET.

Although MPNs are diseases of elderly, MPN is diagnosed in younger age groups in a considerable number of cases. Since most of the available data as well as current WHO classification criteria emphases on the "average" MPN patients who range in age between 55 and 65 years. Less consistent data are available in the groups of patients presenting below this median age, such as children and younger adults which we're planning to reveal.

What participants receive

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

  • Diagnostic (18F-FLT PET/CT)Device

    Also called 18F-FLT PET/CT, 3'-Deoxy-3'-(18F) Fluorothymidine, 3'-deoxy-3'-[18F]fluorothymidine, Fluorothymidine F 18

    The tracer compound [F-18] FLT will be injected into the patient's veins in a small volume of normal saline solution. The PET scan data collection is started immediately and is continued for 2 hours.

Study groups in NCT03121599
Study groupRoleWhat they receive
18F-FLT PET/CTExperimentalPatients undergo 18F-FLT (3'-18Fluoro-3'-deoxy-Lthymidine) PET/CT (Positron Emission Tomography/ Computed Tomography) at baseline. No specific dietary restrictions or hydration are required for FLT-PET scans, however, patients will be urged to drink plenty of water before and after the PET studies. [18F] FLT will be prepared by the cyclotron core facility and assessed for quality control following "good manufacturing practice" criteria. The radiopharmaceutical will immediately be brought to the Molecular Imaging and Therapy Service Radiopharmacy for dispensation in the PET suite. For each scan, patients will receive approximately up to 370 MBq (target of 10 mCi) [18F] FLT by intravenous infusion.

What is being measured

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

  1. Evaluate the uptake of 3'-deoxy-3'-[18F] fluorothymidine (FLT) positron emission tomography/computed tomography (PET) in children with MPNs

    Evaluate the uptake of 3'-deoxy-3'-[18F] fluorothymidine (FLT) positron emission tomography/computed tomography (PET) imaging and it is value in assessing the malignant hematopoiesis in children with MPNs.

    Measured: 12 Months

Secondary outcomes (1)
  1. Number of patients who have similar diagnosis and pattern between FLT and Bone Marrow

    Assessing of WHO diagnostic criteria for diagnosing MPNs. Measurements would include: Bone marrow cellularity, trilineal assessment, megakaryocytic morphologic characteristics (atypia, clustering, size, lobulation), staging of primary myelofibrosis into prefibrotic/early stage, Primary myelofibrosis and overt fibrotic stage prefibrotic, grade of fibrosis, blast percentage, presence of transformation, intrasinusoidal hematopoiesis, dysplasia (if present).

    Measured: 12 months

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 4 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 11 Aug 2020. 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 Qatar. 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.

Are results available for this study?

The study was stopped early (reason given: Delayed study materials, poor recruitment). 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?

Evaluate the uptake of 3'-deoxy-3'-[18F] fluorothymidine (FLT) positron emission tomography/computed tomography (PET) in children with MPNs (time frame: 12 Months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03121599, which also lists 13 linked publications.

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 11 Aug 2020.
