Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to evaluate the use of 89Zr-labeled girentuximab (89Zr-TLX250) as a novel, carbonic anhydrase IX (CAIX) targeted PET/CT tracer for the imaging of metastatic triple negative breast cancer (TNBC) patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The purpose of this study is to evaluate the use of 89Zr-labeled girentuximab (89Zr-TLX250) as a novel, Carbonic Anhydrase IX (CAIX) targeted PET/CT tracer for the imaging of metastatic triple negative breast cancer (TNBC) patients.

TNBC patients are known to be rapidly progressive and have a poor prognosis. This poor prognosis is due to the lack of common breast cancer targets in TNBC. As TNBC expresses CAIX, this stuy will evaluate CAIX targeting by using a radiolabeled monoclonal antibody that recognizes carbonic anhydrase IX (CAIX) : 89Zr- girentuximab otherwise known as 89Zr-TLX250. Previous and ongoing studies have demonstrated the potential application of 89Zr-TLX250 as a new PET/CT imaging tracer for the detection of renal cancer.

After establishing the TNBC targeting properties of the 89Zr-TLX250 PET/CT imaging tracer, it should be interesting to develop a new targeted therapy using TLX250- radiolabeled with a therapeutic radionuclide such as 177Lutétium.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Written informed consent obtained from the patient prior to performing any protocol-related procedures, including screening evaluations.
* Female or male, Age ≥ 18 years at time of study entry.
* Primitive triple negative breast cancer proven histologically, defined according to the following criteria:

* Estrogen receptors \<10%.
* And progesterone receptors \<10%.
* And Human Epidermal Growth factor Receptor 2 (HER2) not amplified or not overexpressed.
* Breast Cancer (BC) recurrence documented by conventional imaging and/or FDG PET/CT with at least one measurable metastatic lesion according to Response Evaluation Criteria In Solid Tumors (RECIST) and/or PET Response Criteria In Solid Tumors (PERCIST).
* Consent to use a contraception method for at least 30 days after administration of 89Zr-TLX250.
* Eastern Cooperative Oncology Group (ECOG) Performance Status 0 or 1.
* Life expectancy at least 6 months.
* Patient has valid health insurance.

Exclusion Criteria

* History of another primary malignancy except for basal cell carcinoma within the last 5 years.
* Chemotherapy, radiotherapy, or immunotherapy within 4 weeks prior to the planned administration of 89Zr-TLX250 or continuing adverse effects (\> grade 1) from such therapy (Common Terminology Criteria for Adverse Events \[CTCAE\] version 5.0).
* Planned antineoplastic therapies (for the period between IV administration of 89Zr-TLX250 and imaging).

* Previous administration of any radionuclide within 10 half-lives of the same.
* Impossibility to hold lying motionless at least 1 hour, or known claustrophobia.
* Serious non-malignant disease (e.g. psychiatric, infectious, autoimmune or metabolic), that may interfere with the objectives of the study or with the safety or compliance of the subject, as judged by the investigator.
* Mental impairment that may compromise the ability to give informed consent and comply with the requirements of the study.
