Trial Summary

What is the purpose of this trial?

The purpose of this study is to see whether 89Zr-ss-pertuzumab is safe in people with HER2+ cancer.

Do I need to stop my current medications for the trial?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

What data supports the effectiveness of the drug 89Zr-ss-pertuzumab for breast cancer?

Research shows that 89Zr-pertuzumab, a component of 89Zr-ss-pertuzumab, is effective in imaging HER2-positive breast cancer, helping to identify patients who may benefit from targeted therapies. It has been successful in detecting HER2-positive metastases even in patients with HER2-negative primary breast cancer, which can guide treatment decisions.12345

Is 89Zr-ss-pertuzumab safe for use in humans?

In a study involving patients with HER2-positive breast cancer, 89Zr-pertuzumab was administered without any toxicities, indicating it was safe for human use in this context.12456

How does the drug 89Zr-ss-pertuzumab differ from other breast cancer treatments?

89Zr-ss-pertuzumab is unique because it is used for imaging rather than direct treatment, helping to identify HER2-positive breast cancer metastases that might not be detected by other methods. This drug is radiolabeled with zirconium-89, allowing it to be used in PET/CT scans to visualize cancer spread and assess HER2 status, which is crucial for determining the appropriate targeted therapy.12345

Findings from Research

This first-in-human study involving 6 patients with HER2-positive metastatic breast cancer demonstrated that 89Zr-pertuzumab PET/CT is safe, with no reported toxicities during the trial.
The imaging technique effectively visualized HER2-positive metastases, confirming its potential for assessing HER2 status in lesions that are difficult to biopsy, and it accurately identified HER2-positive brain metastases in one patient, which was later confirmed by surgical resection.

The study successfully developed an immuno-PET imaging agent, 89Zr-DFO-pertuzumab, which effectively binds to HER2 and allows for visualization of HER2-expressing tumors, demonstrating its potential to monitor therapeutic responses in breast cancer.
In trastuzumab-resistant JIMT-1 breast cancer models, 89Zr-DFO-pertuzumab showed significantly reduced uptake in tumors treated with the HSP90 inhibitor 17-DMAG, indicating its ability to assess treatment efficacy and HER2 downregulation.
Therapeutic Response Monitoring with 89Zr-DFO-Pertuzumab in HER2-Positive and Trastuzumab-Resistant Breast Cancer Models.Kang, M., Shin, JI., Han, S., et al.[2022]
Pertuzumab is an effective treatment for metastatic HER2-positive breast cancer, especially when combined with trastuzumab and docetaxel, showing significant improvements in progression-free and overall survival in treatment-naive patients.
As a HER dimerization inhibitor, pertuzumab works differently than trastuzumab, allowing for a more complete blockade of HER2 signaling, and has a tolerable safety profile, making it a recommended first-line therapy.
