Zirconium-89-girentuximab PET/CT Imaging in Renal Cell Carcinoma

June 16, 2017 updated by: Radboud University Medical Center

Zirconium-89-girentuximab PET/CT Imaging in Patients Suspected of Primary or Relapse Clear Cell Renal Cell Carcinoma: The Impact on Clinical Decision Making.

Girentuximab is an antibody against Carbonic Anhydrase IX (CAIX), an antigen that is expressed on the cell surface of 95% of clear cell RCC (ccRCC). Zr-89-girentuximab PET/CT (Positron Emission Tomography) may be a valuable imaging technique in the diagnosis of patients with RCC. The aim of the present study is to show the impact of the Zr-89-girentuximab PET/CT on the clinical management of ccRCC patients.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

More advanced imaging methods are needed to reliably distinguish benign small renal masses (SRM) from renal cell carcinoma (RCC) to prevent invasive biopsies or unnecessary surgery. Similarly, improved imaging methods are needed for unambiguous detection of lesions suspect for metastatic and relapse RCC during follow-up. Girentuximab is an antibody against Carbonic Anhydrase IX (CAIX), an antigen that is expressed on the cell surface of 95% of clear cell RCC (ccRCC). Zr-89-girentuximab PET/CT may be a valuable imaging technique in the diagnosis of patients with RCC. The aim of the present study is to show the impact of the Zr-89-girentuximab PET/CT on the clinical management of ccRCC patients. Thirty patients will be included in whom conventional diagnostics are inconclusive. During a multidisciplinary team (MDT) the hypothetical next step in the clinical process will be noted (e.g. further diagnostics, treatment or active surveillance). Subsequently, in these patients a Zirconium-89-girentuximab PET/CT will be performed. Patients will receive a single intravenous dose of 5 mg Zirconium-89-girentuximab (37 MBq). A PET/CT scan will be acquired 4 or 5 days after injection. The Zirconium-89-girentuximab PET/CT will be read by a clinician with extensive experience in radiolabeled girentuximab imaging. The results of the PET/CT will be discussed during the MDT and will be used to decide what the next step in the clinical process will be. This step will be compared with the hypothetical next step from the MDT before the scan.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

In order to participate in this study, a subject must meet all of the following criteria:

  1. His or her clinician should face a diagnostic dilemma; e.g.

    • patients with a renal mass of unknown origin, or
    • patients with a primary renal mass in whom it is unclear whether there is metastatic disease, or
    • patients with a history of clear cell RCC with a suspicion of relapse or metastatic disease.
  2. Minimum age 18 years
  3. Signed informed consent

Exclusion Criteria:

  • History of a CAIX-negative or non clear cell RCC.
  • Administration of tyrosine kinase inhibiters within 1 month prior to inclusion.
  • Any medical condition present that in the opinion of the investigator will affect patients' clinical status. - Administration of a radioisotope within 10 physical half lives prior to study enrollment
  • Pregnancy or lactation.
  • Known hypersensitivity or HACA (human anti chimeric antibodies) against Girentuximab.

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

Experimental: Zirconium-89 girentuximab PET/CT
A Zirconium-89-girentuximab PET/CT will be performed 4-5 days after single intravenous injection of 5 mg Zirconium-89-girentuximab (37 MBq).
Drug: Zirconium-89 girentuximab PET/CT
Thirty patients (suspected of ccRCC) will be included in whom conventional diagnostics are inconclusive. During a multidisciplinary team (MDT) the hypothetical next step in the clinical process will be noted. Subsequently, in these patients a Zirconium-89-girentuximab PET/CT will be performed 4-5 days after single intravenous injection of 5 mg Zirconium-89-girentuximab (37 MBq). The results of the PET/CT will be discussed during the MDT and will be used to decide what the next step in the clinical process will be. This step will be compared with the hypothetical next step from the MDT before the scan. Whether or not the PET/CT scan had impact on clinical decision making will be assessed for each individual patient.
