About this study

Official title: Technetium-99m/Rhenium-188 Labeled Anti-HER2 Single Domain Antibody (99mTc/188Re-NM-02) for HER2 Expression Detection and Radionuclide Therapy in Breast Cancer

To evaluate the safety, dosimetry and efficacy of 99mTc/188Re labeled anti-HER2-single domain antibody (Product Code Name: 99mTc-NM-02 and 188Re-NM-02) SPECT/CT imaging of HER2 expression and radionuclide therapy in Breast Cancer. The SPECT/CT results will compare with the existing gold standard " HER2 expression detection" by biopsy tissue immunohistochemistry (IHC) and/or Fluorescence in Situ Hybridization (FISH) method, and 18F-FDG PET/CT imaging. It also to establish a new theranostic method for non-invasive HER2 expression detection and radionuclide therapy in breast cancer using 99mTc/188Re labeled anti-HER2 single domain antibody.

Read the detailed description

Anti-HER2 single domain antibody will be labeled with 99mTc and 188Re to prepare 99mTc-NM-02 and 188Re-NM-02, respectively. 99mTc-NM-02 is used as a diagnostic agent for SPECT/CT imaging of HER2 expression, and 188Re-NM-02 is used as a therapeutic drug for radionuclide therapy of HER2-postive Breast Cancer.

What is being measured

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

  1. Visual Assessment of HER2 expression in Breast cancer using 99mTc-NM-02 SPECT/CT Scan

    Visual analysis will be carried out by 4 experienced nuclear medicine physicians to observe the uptake of 99m-Tc-NM-02 in breast malignant lesions. A 4-point system will be used to interpret the scans for abnormalities. It is categorised as such: score 0, no abnormal increased uptake; score 1, low increased uptake; score 2, moderate increased uptake; score 3, high increased uptake. The lesion will be considered positive for malignancy if the score is 2 or higher.

    Measured: 1 year

  2. Semiquantitative Assessment of Breast and other Metastatic Lesions in 99mTc-NM-02 SPECT/CT Scan

    Each subject will be administered 3-12 MBq/kg of 99mTc-NM-02 and the semiquantitative analysis of the region of interest (ROI) will be performed in breast and other metastatic lesions. Higher level of HER2 expression (Tumor proportion score, TPS), higher ROI in tumor.

    18F-FDG PET/CT, HER2 IHC and/or FISH used as comparators.

    Measured: 2 years

  3. Safety of 99mTc-NM-02 through Adverse Event Monitoring

    Subjects will be observed for safety after administration of 99mTc-NM-02, and will do follow up at 7 days p.i. Subjects will do blood test to observe for abnormalities in clinical parameters and compare to baseline results.

    Measured: 2 years

  4. Changes of 99mTc-NM-02 uptake

    The changes of tumor volume and maximum standard uptake value (SUVmax) will be recorded in primary and metastatic lesions

    Measured: 2 years

  5. Safety of 188Re-NM-02 through Adverse Event Monitoring

    Subjects will be observed for safety after administration of 188Re-NM-02, and will do follow up at 28 days p.i. Subjects will be contacted by investigator by phone and asked several questions related to subject's health after 188Re-NM-02 injection and concomitant drugs.

    Measured: 2 years

Secondary outcomes (1)
  1. Therapeutic evaluation of HER2 overexpressed Breast Cancer using 188Re-NM-02

    Ten patients will be administered 66 MBq/kg of 188Re-NM-02, and the changes of tumor volume and maximum standard uptake value (SUVmax) will be recorded in breast and other metastatic lesions to analyze treatment effect.

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Injection of 99mTc-NM-02 and Injection of 188Re-NM-02 in people with Breast Cancer and Radiotoxicity, run by Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine 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 6 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 9 Dec 2024. 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?

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?

Visual Assessment of HER2 expression in Breast cancer using 99mTc-NM-02 SPECT/CT Scan (time frame: 1 year). 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?

On the ClinicalTrials.gov record for NCT04674722, which also lists 4 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 9 Dec 2024.
