What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing a new treatment for advanced kidney cancer using a specific protein. The treatment combines a drug that targets cancer cells with another drug that helps the body’s immune system fight the cancer. The goal is to see if this combination is safe and effective.

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

The trial protocol does not specify if you need to stop taking your current medications. However, it mentions that patients on therapeutic anticoagulation should be on a stable dose, which suggests that some medications may be continued. It's best to discuss your specific medications with the trial team.

What makes the drug Nivolumab + 177Lu-girentuximab unique for kidney cancer?

This drug combines Nivolumab, which helps the immune system attack cancer cells, with 177Lu-girentuximab, a targeted therapy that delivers radiation directly to kidney cancer cells by binding to a specific protein (CAIX) on their surface. This dual approach aims to enhance treatment effectiveness by both boosting the immune response and directly targeting cancer cells with radiation. ^{1 2 3 4 5}

What data supports the effectiveness of the treatment Nivolumab + 177Lu-girentuximab for kidney cancer?

A study on 177Lu-girentuximab showed that it helped stabilize the disease in 9 out of 14 patients with advanced kidney cancer, although some patients experienced significant side effects that limited further treatment. ^{1 2 3 4 5}

Are You a Good Fit for This Trial?

This trial is for adults over 18 with advanced kidney cancer that has clear cell features and the CAIX protein. Participants must have had at least one prior systemic therapy, including an anti PD-1 or PD-L1 antibody, and cannot join if they've had certain treatments recently, have severe allergies to specific antibodies, uncontrolled infections like HIV or hepatitis B/C, untreated brain metastases larger than 1cm or symptomatic of any size, a history of significant cardiovascular disease within the past three months, or are pregnant.

What Are the Treatments Tested in This Trial?

Interventions

• 177Lu-labeled-girentuximab
• Nivolumab

Trial Overview The study tests whether combining Nivolumab (an immunotherapy drug) with a radioactive drug called 177Lu-girentuximab is safe and works against kidney cancer. Patients will also undergo scans using another substance called 89Zr-girentuximab to see how the tumor responds.

How Is the Trial Designed?

Group I: Safety lead-in Phase: Participants with Advanced or Metastatic Clear Cell Renal Cell Carcinoma/RCC Experimental Treatment 4 Interventions

Participants have Advanced or Metastatic Clear Cell Renal Cell Carcinoma/RCC. The protocol will start with a safety-lead in phase using a 3+3 design to establish the maximal tolerated dose (MTD) of 177Lu-labeled-girentuximab in combination with standard-dose nivolumab. The initial starting dose of 177Lu-labeled-girentuximab is 1804 MBq/m2 which is 75% of the single agent dose established in prior studies and will proceed as shown in the schema below. Once the MTD is established, a Simon two-stage optimal design will commence. 10 patients will be enrolled in the first stage and if no responses are observed, the study will be terminated. If 1 or more responses are observed in the first 10 patients, we will extend enrollment to a total of 29 patients (19 additional patients) in the second stage.

Group II: Phase 2 Participants Experimental Treatment 4 Interventions

Participants have Advanced or Metastatic Clear Cell Renal Cell Carcinoma/RCC. If 1 or more responses are observed in the first 10 patients, we will extend enrollment to a total of 29 patients (19 additional patients) in the second stage.

Published Research Related to This Trial

The study demonstrated that dual-labeled girentuximab can specifically target clear cell renal cell carcinoma (ccRCC) tissue, allowing for effective visualization of tumors during surgery using both radionuclide and fluorescence imaging techniques.

In a trial involving seven human kidney specimens, the maximum uptake of girentuximab in tumor tissue was significantly higher (up to 0.33% of the injected dose per gram) compared to normal kidney tissue (up to 0.04% ID/g), confirming its potential for precise tumor detection in clinical settings.

The phase I study involving 10 patients showed that [89Zr]Zr-DFO-girentuximab is safe and well tolerated, with no serious treatment-related adverse events reported, indicating its potential for clinical use.

89Zr-girentuximab PET/CT imaging effectively differentiated clear cell renal cell carcinoma (ccRCC) from non-ccRCC lesions in all patients, providing a quantitative assessment of tumor dosimetry, which is crucial for treatment planning.

In the ARISER trial involving 864 patients with high-risk clear cell renal cell carcinoma (ccRCC), girentuximab did not show a statistically significant improvement in disease-free survival (DFS) or overall survival (OS) compared to placebo, indicating it may not be an effective adjuvant treatment.

Despite the lack of clinical benefit, the study reported a median DFS of 71.4 months for the girentuximab group, suggesting that patients may have longer survival times than expected, which poses challenges for future drug development in this area.

In a phase 2 trial involving 14 patients with metastatic clear cell renal cell carcinoma, lutetium 177-girentuximab radioimmunotherapy led to disease stabilization in 9 patients (64%), indicating its potential efficacy in treating this challenging condition.

While the treatment was generally well tolerated, it caused significant myelotoxicity, leading to prolonged low blood cell counts that prevented some patients from receiving retreatment.

Girentuximab (cG250) effectively targets carbonic anhydrase IX (CAIX) on renal cancer cells, and its labeling with 177Lu for radioimmunotherapy has been optimized to maintain immunoreactivity, crucial for effective treatment.

In vivo studies showed that tumor uptake of the radiolabeled cG250 was less than 10% ID/g, attributed to factors like necrotic areas, heterogeneous CAIX expression, and low vascularity, which may limit the effectiveness of this therapy.
