Sunitinib for Metastatic Renal Cell Cancer With Imaging Biomarker Assessments for the Early Prediction of Tumor Response

Completed · Phase 1

Conditions studied: Renal Cell Cancer

In brief

This exploratory clinical study is designed to obtain pre-therapeutic imaging assessments in 20 evaluable patients with metastatic renal cell cancer (RCC) and an early post therapy assessment at baseline and at various early time points (1 week in 5 patients, 2 weeks in 5 patients, 3 weeks in 5 patients and 4 weeks in 5 patients) after institution of standard approved sunitinib therapy at 37.5 mg/day. The clinical imaging biomarkers will include an assessment of tumor metabolism \[Bannasch 1986, Frauwirth 2002, Garber 2006, Kelloff 2005, Pauwels 1998, Semenza 2001, Smith 1999, Smith 2000, Sokoloff 1977, Warburg 1956, Weber 1977A, Weber 1977B\] (dynamic FDG-PET); tumor proliferation \[Rasey 2002,Shields 2001, Shields 1998, Vesselle 2002, Schwartz 2003\] (dynamic FLT-PET); tumor blood flow (H215O-PET, DCE MRI)\[Lodge 2000\], tumor perfusion (DCE-MRI)\[Tofts 1999, Tofts 1997, Parker 1999\]; and tumor blood volume (H215O-PET, DCE MRI)\[Lodge 2000, Tofts 1999, Tofts 1997\] in the same patient at baseline and then in the same patient at one of the post therapy time points (1 week, 2 weeks, 3 weeks or 4 weeks). We hypothesize that by using this set of imaging assessments it will be possible to determine an individual or more likely a set of imaging derived biomarkers that will accomplish several of the goals of the initiative which is providing funding for the study.

Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

Patients must be 18 years or older for inclusion in this study. Since there is no experience with [F-18]FLT in children and it would be inappropriate to study individuals under the age of 18 until more safety data is available.
After entry into the study, patients are expected to be followed for at least 2 months as part of standard of care.
All patients, or their legal guardians, must sign a written informed consent and HIPAA authorization in accordance with institutional guidelines.
The patient, if female, must be postmenopausal for a minimum of one year or surgically sterile, or on one of the following methods of birth control for a minimum of one month prior to entry into this study: IUD, oral contraceptives, Depo-Provera or Norplant. These criteria can be waived at the discretion of the investigator if the patient's tumor is considered life threatening and the one month wait required is not in the best interest of the patient. Negative pregnancy test is accepted.
Pre-treatment laboratory tests for patients receiving [F-18]FLT must be performed within 21 days prior to study entry. These must be less than 4 times below or above the upper or lower limit range for the respective laboratory test. These will include liver enzymes (SGOT, SGPT, ALK Phos, GGT, LDH), bilirubin (direct and total), amylase, serum electrolytes, CBC with platelets and absolute neutrophil counts, prothrombin time, partial thromboplastin time, BUN, creatinine, and urinalysis.
Pre-treatment radiological clinical scans/studies (Gd- enhanced MRI or CT to document metastatic renal cell carcinoma) must be performed within 30 days of study entry.

You may not qualify if…

Patients with known allergic or hypersensitivity reactions to previously administered radiopharmaceuticals or Gd used in MRI imaging. Patients with significant drug or other allergies or autoimmune diseases may be enrolled at the Investigator's discretion.
Patients who are pregnant or lactating or who suspect they might be pregnant.
Adult patients who require monitored anesthesia for PET or MRI scanning.
HIV positive patients due to the previous toxicity noted with FLT.
Renal Insufficiency Exclusion for MRI contrast injection. All subjects will be screened as to their renal status and those patients with renal insufficiency will be excluded from undergoing a dynamic contrast enhanced MRI scan. This is in response to the recent association of MRI contrast agents with the development of Nephrogenic Systemic Fibrosis (NSF). The patient will have a creatinine value determined within 4 weeks prior to the proposed MRI scan and have a GFR determined from the creatinine value and other data that can be used at various websites to determine the GFR. If the GFR is greater than 60 ml/min/then the patient will be deemed eligible for contrast injection. If the GFR value is between 40 ml/min and 60 ml/min the risk versus benefit of performing the contrast injection will be discussed with the referring physician and the patient. If the GFR is less than 40 ml/min the dynamic contrast study will not be performed. The non-contrast MRI scan however will be obtained for anatomic reference for the PET studies.
MRI exclusion criteria:
Presence of any ferromagnetic metallic implants or foreign bodies, including pacemakers and certain types of stents and orthopedic hardware.
Claustrophobia or inability to remain stationary within MRI system for \~30-45 minutes.
Inability to breath hold for periods of at least 20 seconds.
Known history of adverse reaction to Gd chelate contrast agents.
Pregnancy or breastfeeding.
Non-imageable tumor, including tumors with smallest dimension less than 10mm or tumors located in regions excessively affected by susceptibility artifacts at bone- and air-tissue interfaces or motion artifacts due to peristalsis or pulsatile flow.
