Study Overview

Study Assessing PET Imaging With Zirconium-labelled Girentuximab in Patients With HCC, ICC or NEN

Precision medicine represents a major goal in oncology. It has its underpinning in the identification of biomarkers with diagnostic, prognostic, or predictive values. Gastro-entero-pancreatic neuroendocrine neoplasia (GEP-NENs) are rare tumors, but their frequency is increasing. In this context, the tumor expression of carbonic anhydrase IX (CAIX), complemented by a restricted profile in normal tissues, provides an opportunity for therapeutic targeting and precision medicine. Indeed, radiolabeling the anti-CAIX monoclonal antibody girentuximab with Zirconium 89 has shown promise as a novel positron emission tomography (PET) tracer and labeling with 177 Lutetium promise as a therapeutic agent in clear cell renal cell carcinoma (ccRCC) in the context of a theranostic approach. 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 Gastro-Entero-Pancreatic Neuroendocrine Neoplasms, Hepatocellular Carcinoma or IntraHepatic Cholangiocarcinoma.

Diagnostic efficacySensitivity of 89Zr-TLX250 PET/CT in the detection of tumor lesions as compared to a composite truth standard (determined on the basis of histology and conventional morphological or PET imaging).Month 3
Diagnostic efficacyConcordance of 89Zr-TLX250 PET/CT in the detection of tumor lesions as compared to a composite truth standard (determined on the basis of histology and conventional morphological or PET imaging).Month 3
Assessment of tumor uptakeTumor quantitative measures on 89Zr-TLX250 PET.Day 8
Correlation with CAIXAssessment of the correlation between the normalized uptake values (SUVmax) of 89Zr-TLX250 positive lesions and CAIX histological expression will be done by comparing the 89Zr-TLX250 semi-quantitative data with the immunohistochemical results (IHC) of biopsied lesions.Day 8

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person’s general health condition or prior treatments.

Ages Eligible for Study:
ALL

Sexes Eligible for Study:
18 Years

Accepts Healthy Volunteers:

    Inclusion Criteria:
    1. Provided written informed consent. 2. Patients aged ≥ 18 years. 3. Histologically confirmed, unresectable locally advanced or metastatic solid tumors of:

  • HCC or ICC: expressing CAIX (less than 2 years), not eligible for local or loco- regional treatment, after failure of first line systemic therapy. In addition, for ICC, after targeted therapy in case of IDH1 mutation or FGFR fusion.
  • Progressive GEP-NENs (2019 WHO classification), functioning or non-function- ing, without or with low SSTR2 expression, after at least one line of standard therapy. 4. Presence of at least one morphological evaluable lesion according to RECIST 1.1 using contrast CT/MRI. 5. Patients should not have received further antitumor therapy once disease progression is documented. 6. Patients must have an ECOG (Eastern Cooperative Oncology Group) performance status of 0 to 2. 7. For cirrhotic patients: Child-Pugh A. 8. Patient affiliated to or beneficiary of the National Health Service.

  • Exclusion Criteria:
    1. Known hypersensitivity to zirconium-89, to any excipient or derivative or to radiographic contrast agents. 2. Chemotherapy, extensive external beam radiation, immunotherapy, targeted therapy, or angiogenesis inhibitors within 4 weeks prior to inclusion. 3. Radionucleide targeted therapy prior to inclusion within 6 months prior to inclusion. 4. Radioembolization within 3 months prior to inclusion. 5. Uncontrolled brain or spinal cord metastasis. Patients with a history of brain metastases must have a head CT or MRI with contrast to document stable brain disease 3 months prior to inclusion in the study. 6.
