About this study

Official title: 68Ga-DOTATATE PET/CT for Detection and Evaluation of the Causative Tumor of Oncogenic Osteomalacia

Oncogenic osteomalacia is rare disease predominantly caused by a small, somatostatin receptor positive mesenchymal tumor, which is frequently hidden in an unusual anatomical site and often goes undetected by conventional imaging. A permanent cure of the disease relies on exactly localizing the tumor and completely removing it. 68Ga-DOTATATE PET/CT is a novel scan that might have improved sensitivity and resolution specifically for somatostatin receptor positive tumors. The investigators will scan the suspicious and confirmed patients of oncogenic osteomalacia and compare it to 99mTc-HYNIC-TOC SPECT/CT and 18F-FDG PET/CT to see if it improves patient care.

Read the detailed description

Oncogenic osteomalacia, or tumor-induced osteomalacia, is a rare, serious paraneoplastic syndrome. It is predominantly driven by a small, benign mesenchymal tumor. The disease is readily prompted by the clinical features such as hyperphosphaturia, hypophosphatemia, low serum vitamin D3 levels, elevated serum fibroblast growth factor 23 levels, and osteomalacia. However, the causative tumor is frequently hidden in an unusual anatomical site and often goes undetected by conventional imaging, such as computed tomography (CT), while a permanent cure of the disease will only rely on exact localization and completely removal of the tumor.

Since mesenchymal tumors express somatostatin receptors (SSR), molecular imaging using radiolabeled somatostatin analogs may be one of the best ways to detect the small, occult tumors. 111In- and 99mTc-labeled octreotide and analogs have been proved useful to detect mesenchymal tumor and other SSR-positive tumors. However, the scintigraphy is insufficient to provide high-resolution images and precise anatomical information. In this study, a novel approach was proposed for exact localization of mesenchymal tumors through positron emission tomography (PET) imaging with 68Ga-DOTATATE and co-registration with CT. 68Ga-DOTATATE PET/CT is a novel method that might have improved sensitivity and resolution specifically for SSR-positive tumors, including the causative tumor of oncogenic osteomalacia.

The investigators will scan the patients in suspicion of oncogenic osteomalacia and the confirmed oncogenic osteomalacia patients in suspicion of relapse or with residual tumor after surgery, and compare it to 99mTc-HYNIC-TOC SPECT/CT and 18F-FDG PET/CT of the same patients. The aim of the study was to see if 68Ga-DOTATATE PET/CT can detect more tumors with higher resolution and more exact localization, and then help to develop optimal treatment strategy and improves patient care.

What participants receive

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

  • 68Ga-DOTATATEDrug

    Also called (68)Ga-DOTA-d-Phe(1),Tyr(3)-octreotate

    Intravenous injection of one dosage of 72-185MBq (2-5 mCi) 68Ga-DOTATATE solution. Tracer doses of 68Ga-DOTATATE will be used to image tumors by Positron Emission Tomography / computed tomography (PET/CT)

What is being measured

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

  1. Number and location of lesions detected by 68GA-DOTATATE PET/CT compared to 99mTc-HYNIC-TOC SPECT/CT and/or 18F-FDG PET/CT

    Determine if the 68Ga-DOTATATE PET/CT changes care plans compared to conventional imaging/diagnostic techniques (99mTc-HYNIC-TOC SPECT/CT, and/or 18F-FDG PET/CT, MRI, CT, ultrasonography).

    Measured: 1 year

Secondary outcomes (1)
  1. Number of participants and kinds of adverse events as a measure of safety

    Determine if any adverse effects are associated with the scan and the number of patients that experience them.

    Measured: One year

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing 68Ga-DOTATATE in people with Oncogenic Osteomalacia and Mesenchymal Tumor, run by Peking Union Medical College Hospital at 1 site in China.

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 3 inclusion and 8 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: status not confirmed, as of the sponsor's last update on 7 Apr 2017. 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 China. 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?

Results are not available in the source record.

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

Contact Fang Li, MD (86-10-65295502, lifang@pumch.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number and location of lesions detected by 68GA-DOTATATE PET/CT compared to 99mTc-HYNIC-TOC SPECT/CT and/or 18F-FDG PET/CT (time frame: 1 year). 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 7 Apr 2017.
