About this study

Official title: Phase I Open Label Trial of Pharmacokinetics and Safety of 99mTc Niacinamide Polyethylene Glycol Bicyclic RGD Peptide (99mTc-3PRGD2) Injection in Healthy Volunteers

The study drug 99mTc-3PRGD2 of this study is a new radioactive diagnostic preparation for clinical use as a nuclear medicine molecular probe for tumor SPECT/CT imaging.

After 99mTc-3PRGD2 is injected into the body, it is specifically taken up by integrin receptor-positive tumor tissue, and tumor tissue is developed by SPECT/CT, which can be used for molecular imaging diagnosis and individualized treatment of common tumors.

The primary objectives of this study is to examine the pharmacokinetics the safety of 99mTc-3PRGD2 injection in healthy volunteers, as well as the biodistribution in the human body and to estimate the dose of internal radiation absorbed. This study provides the basis for the design of phase II clinical research programs.

Read the detailed description

To a large extent, cancer treatment outcomes depend on the accurate diagnosis and staging of the disease. An important basis for early diagnosis of malignant tumors is medical imaging. Single-Photon Emission Computed Tomography (SPECT) and Positron Emission Tomography (PET) are most well-developed nuclear medicine procedures based on the measurement of radiolabeled tracer molecules.

These radiotracers allow biologic processes to be measured and whole body images to be obtained, which will demonstrate exact locations of radiotracer accumulation. Functional imagings of SPECT and PET provide specific information which is not available from standard medical imaging modalities such as ultrasound, X-ray, computerized tomography (CT) or magnetic resonance imaging (MRI).

The test drug in this study is a new radioactive diagnostic preparation, consisting of radiochemical (Sodium Pertecheetate [99mTc] Injection) and a kit (including Three core ligands, HYNIC-3PRGD2, Tricine, TPPTS). Before administration, 99mTc:HYNIC-3PRGD2:Tricine:TPPTS (1:1:1:1) chelate compound (99mTc-3PRGD2) will be prepared as per standard opration presedure, which will be used as a molecular probe for SPECT/CT imaging.

The core ligand HYNIC-3PRGD2 is a novel RGD dimer that specifically binds to the integrin αvβ3 receptor with high selectivity and affinity. Integrin αvβ3 is highly expressed in tumor neovascularization. After injection, 99mTc-3PRGD2 will be specifically taken up by the integrin receptor-positive tumor tissue, then be imaged by SPECT/CT. The product can be used for molecular imaging diagnosis and individualized treatment for common tumors such as lung cancer and breast cancer are performed.

The primary objectives of this study is to examine the pharmacokinetics the safety of 99mTc-3PRGD2 injection in healthy volunteers, as well as the biodistribution in the human body and to estimate the dose of internal radiation absorbed. This study provides the basis for the design of phase II clinical research programs.

What is being measured

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

  1. AUC(0-t)

    Area under the Activity-time curve from Hour 0 to the last measurable activity

    Measured: Day 1(dosing day )and Pre-dose,1,2,3,19,33,53,91,120,245 minutes post dose

  2. The %ID(The radioactivity of the urine at each time period/ the total injection activity)

    The %ID(The radioactivity of the urine at each time period/ the total injection activity) is calculated

    Measured: Day 1(dosing day)and Pre-dose,0-50 minutes,50-120 minutes,2-4 hours, 4-8 hours,8-12 hours,12-24hours post dose

  3. The %ID(The radioactivity of the main organs at each time period/ the total injection activity)

    The %ID(The radioactivity of the main organs at each time period/ the total injection activity) is calculated.

    Measured: post-intervention at 4 months

  4. The radiation dosimetry of the test drug in organs

    The internal radiation dosimetry (Dt,mSv) of each irradiated organ is calculated.

    Measured: post-intervention at 4 months

  5. Radiochemical purity

    To reflects the stability of the drug in the human body,that Radiochemical purity in urine and blood samples is measured.

    Measured: During procedure

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing 99mTc niacinamide polyethylene glycol bicyclic RGD peptide (99mTc-3PRGD2) in people with Healthy, run by RDO Pharm. 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 5 inclusion and 11 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: finished, as of the sponsor's last update on 8 Aug 2019. 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?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

AUC(0-t) (time frame: Day 1(dosing day )and Pre-dose,1,2,3,19,33,53,91,120,245 minutes post dose). 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 8 Aug 2019.
