An Exploratory Study of 89Zr-DFO-Atezolizumab ImmunoPET/CT in Patients With Locally Advanced or Metastatic Renal Cell Carcinoma

This is an exploratory clinical trial to assess the potential of 89Zr-DFO-Atezolizumab Positron Emission Tomography/Computed Tomography (PET/CT) scans in patients with locally advanced or metastatic renal cell carcinoma (RCC). This open label, nontherapeutic trial will test the correlation of 89Zr-DFO-Atezolizumab immunoPET/CT with programmed death-ligand 1 (PD-L1) expression and the response to immune checkpoint inhibitor therapy in patients with RCC. There will be two cohorts, one made up of patients with localized RCC who will undergo 89Zr-DFO-Atezolizumab PET/CT prior to nephrectomy and a second cohort of patients with metastatic RCC who will undergo 89Zr-DFO-Atezolizumab PET/CT prior to treatment with an immune checkpoint inhibitor.

Determining the Magnitude of Change in [18F]FPIA-detectable Short Chain Fatty Acid Uptake in Metastatic Renal Cell Cancer Following Therapy

Renal cell carcinoma (RCC) is the most prevalent and lethal malignancy of the kidney. At the time of diagnosis, as many as a fifth of patients have metastatic disease (mRCC). Despite advances in treatment, long-term survival rates remain poor. 18F-fluoropivalate ([18F]FPIA) is a new tracer that images short chain fatty acid (SCFA) uptake in tumours, a key component of fatty acid oxidation. The aim of the study is to investigate longitudinal changes in [18F]FPIA uptake at baseline, at 4-6 weeks and at 12 weeks following treatment initiation in patients using tyrosine kinase inhibitors (TKI's), chemotherapy, immunotherapy, or combinations of these. The investigators hypothesise that the import of [18F]FPIA-detectable SCFA into tumours is high and decreases with effective treatment.

An Exploratory Study of [18F]PT2385 PET/CT in Patients With Renal Cell Carcinoma

This is an exploratory study to assess [18F]PT2385 Positron Emission Tomography/Computed Tomography (PET/CT) in patients with renal cell carcinoma (RCC). This is an open-label, nontherapeutic trial. The main objective is to correlate hypoxia-inducible factor-2alpha (HIF2α) levels as determined by an investigational [18F]PT2385 PET/CT scan with the levels on subsequently obtained tissue by HIF2α immunohistochemistry (IHC). There will be two cohorts. The first pre-surgical cohort will have [18F]PT2385 PET/CT prior to nephrectomy. The uptake and retention on Positron Emission Tomography (PET), quantified as standardized uptake value (SUV) max and mean, abbreviated SUV henceforth will be correlated with HIF2α levels by IHC on the primary tumor. The second cohort will comprise patients with metastatic clear cell renal carcinoma (ccRCC). SUV will be correlated with HIF2α levels measured by IHC on a biopsy sample from a metastasis. Both low- and high-avidity sites will be biopsied and tracer uptake correlated with HIF2α IHC.

A Phase 2 Open-label Study of Nivolumab Combined With Lutetium 177-Labeled Anti-Carbonic Anhydrase IX Monoclonal Antibody Girentuximab in Patients With Clear Cell Advanced Renal Cell Carcinoma

The purpose of this study is to see if the combination of 177Lu-girentuximab and nivolumab is a safe and effective treatment for advanced clear cell renal cell carcinoma/ccRCC that has the CAIX protein.

A Multicenter, Open-Label, Non-Randomized Phase 1/2 Study to Assess Safety, Tolerability and Imaging Characteristics of [68Ga]Ga-DPI-4452 and to Assess Safety, Tolerability, and Efficacy of [177Lu]Lu-DPI-4452 in Patients With Unresectable Locally Advanced or Metastatic Solid Tumors

The main purpose of Part A of the study is to evaluate safety, tolerability and tracer uptake after a single intravenous (IV) administration of [68Ga]Ga-DPI-4452; Part B: is to determine the recommended phase 2 dose (RP2D) [maximum tolerated dose (MTD) or lower dose] for [177Lu]Lu-DPI-4452 for each tumor type; Part C: is to evaluate the preliminary antitumor activity of [177Lu]Lu-DPI-4452 as monotherapy.

68Ga-NY104 PET/CT and 18F-FDG PET/CT in Patients With Metastatic Clear Cell Renal Cell Carcinoma: a Prospective, Single Center, Single Arm, Comparative Imaging Trial

This is a prospective, single-center, single-arm, comparative phase 2 study in patients with metastatic clear cell renal cell carcinoma. The goal is to determine the sensitivity of 68Ga-NY104 PET/CT in patients with metastatic clear cell renal cell carcinoma and compare it with 18F-FDG PET/CT.

68Ga-NY104 PET/CT for the Detection of Clear Cell Renal Cell Carcinoma in Presurgical Patients With Renal Masses

This is a prospective, single-center, single-arm, diagnostic phase 2 study in patients who have renal masses scheduled for surgical resection. The goal is to determine the sensitivity and specificity of 68Ga-NY104 PET/CT in the detection of clear cell renal cell carcinoma using histopathological diagnosis as ground truth, in patients with operable renal masses.

68Ga-NY104 PET/CT Imaging in Patients With Confirmed or Suspicious Renal Cell Carcinoma

This is a prospective, single-center study in patients with renal cell carcinoma. The goal is to determine the sensitivity and specificity of 68Ga-NY104 PET/CT in the detection of clear cell renal cell carcinoma.

Head-to-head Comparison of Positron Nuclide Radio-labeled FAPI and 18F-FDG PET/CT in Patients With Malignant Tumors

The latest research has found that the use of positron-labeled FAP inhibitors for targeting FAP has achieved very good results in displaying tumor stroma, especially for tumors with poor FDG PET/CT observation, such as liver cancer, renal cancer, and gastric cancer. Although the studies were based on small sample data or case reports, they achieved significantly better results than 18F-FDG [13,15-17].

Comparison of [18F] PSMA-1007 PET/CT and Conventional Imaging in the Detection of Metastatic Clear Cell Renal Cell Carcinoma

Staging of kidney cancer is primarily achieved by computerized tomography (CT) scans or magnetic resonance imaging (MRI). If a patient is found to have limited metastatic disease, surgical removal or radiation therapy could be considered in order to control the majority of the disease. However, if metastases are more widespread, systemic (drug) therapy may be the preferred management option. The identification of additional metastatic sites using more sensitive imaging modalities therefore has the potential to alter management, and this remains an unmet need in the field. This study will investigate the utility of positron emission tomography (PET) imaging with PSMA (prostate specific membrane antigen). Kidney cancer of the clear cell subtype has demonstrated high expression of PSMA, making it a disease in which PSMA-targeted PET imaging could help to identify occult metastatic disease.
