Brief Summary:
The primary objective of this research is to evaluate response to anti-angiogenesis therapy via 18F-DCFPyL prostate-specific membrane antigen (PSMA)-based positron emission tomography/computed tomography (PET/CT) in patients with metastatic renal cell carcinoma (RCC) and to compare qualitatively with conventional imaging response criteria - Response Evaluation Criteria In Solid Tumors (RECIST 1.1) and histopathological endpoints including isolation, enumeration and staining of Circulating Tumor Cells (CTC).

Condition or disease Intervention/treatment Phase
Renal Cell Carcinoma Drug: PSMA-based 18F-DCFPyL PET tracer for PET/CT exams Phase 2

Detailed Description:

Response of anti-angiogenesis therapy will be quantified using PSMA-based PET imaging using a novel agent,18F-DCFPyL, as a non-invasive imaging biomarker of tumor neovasculature to functionally monitor renal cell cancer neovasculature in patients undergoing systemic anti-angiogenesis therapy. PSMA PET will be compared with response to anti-angiogenesis therapy using conventional imaging computed tomography(CT)-based RECIST1.1 criteria as well as histopathological endpoints (tumor vascular density, immunohistochemical staining for PSMA and neovascularization (cluster of differentiation(CD)105, CD31). Whole body PSMA PET/CT scans will be obtained at baseline, following adjuvant anti- angiogenic therapy and when the patient becomes refractory to treatment.

The rationale and time points for obtaining PET scans is planned with respect to the typical natural history of metastatic RCC. This project will obtain information from tumors that are responding to anti-angiogenesis therapy and those resistant to treatment.

Arm Intervention/treatment
Experimental: 18F-DCFPyL whole body PET/CT scan
18F-DCFPyL whole body PET/CT scan at three time-points
Drug: PSMA-based 18F-DCFPyL PET tracer for PET/CT exams

18F-DCFPyL whole body PET/CT scan administered at the following timepoints:

  1. Prior to scheduled nephrectomy
  2. After completion of systemic antiangiogenesis therapy
  3. When patient is refractory to treatment
Other Name: PSMA PET

Primary Outcome Measures :
  1. RECIST 1.1 Based Criteria [ Time Frame: Up to 24 months ]
    Compare number of lesions identified on PSMA versus standard of care imaging base on RECIST 1.1 criteria.

  2. HIstopathological Endpoints [ Time Frame: Up to 24 months ]
    Compare PSMA imaging to histopathological endpoints which include tumor vascular density, immunohistochemical staining for PSMA and neovascularization (CD105, CD31 markers)

Secondary Outcome Measures :
  1. Measure therapy response of patient specific uVESSEL (a micro scale organotypic co-culture model) [ Time Frame: Up to 24 months ]
    Patient-derived uVESSEL models (from primary & metastatic sites) will be tested for response to anti-angiogenic therapies including pazopanib, sunitinib, cabozantinib, and axitinib. Response will be quantified via multiple endpoints, e.g. vessel sprouting, PSMA expression, cell death.

  2. Evaluate the predictive power and validate the uVESSEL model [ Time Frame: Up to 24 months ]
    Using the clinical, pathological and imaging endpoints, predictive models will e developed using responses to uVESSEL model above. More specifically the objective response (dichotomous endpoint of yes or no) measured using PSMA-based PET/CT will be used as a dependent variable in a logistic regression model with response to uVESSEL model from above as an independent predictor to segregate uVESSEL responses into two groups corresponding to responders and non-responders to anti-angiogenic therapies.
