Clinical Trial Summary

The goal of this clinical research study is to learn if sunitinib malate (SU011248) can help to control VHL. The safety of this drug will also be studied.

Primary objectives:

• Evaluate safety of treatment with SU011248/sunitinib malate (50 mg daily dose for 4 weeks, then 2 weeks off) for 6 months in patients with Von Hippel-Lindau Syndrome (VHL) who have a measurable lesion undergoing surveillance

Secondary objectives:

• Evaluate efficacy of treatment with SU011248/sunitinib malate (50 mg daily dose for 4 weeks, then 2 weeks off) for 6 months in patients with VHL who have a measurable lesion undergoing surveillance

Correlative objectives:

• Evaluate quality of life of SU011248/sunitinib malate therapy in VHL patients

• Evaluate peripheral blood lymphocyte receptor phosphorylation in VHL patients taking SU011248/sunitinib malate (optional procedure)

• Correlate results of dynamic contrast-enhanced and diffusion weighted MRI and dynamic contrast enhanced CT with response and explore findings suggestive of surrogates of early response (optional procedure)

Description:

Sunitinib malate is designed to block pathways that control important events such as the growth of blood vessels that are essential for the growth of cancer.

Before you can start treatment on this study, you will have what are called "screening tests." These tests will help the doctor decide if you are eligible to take part in this study. You will have standard scans to check the status of your disease, including computed tomography (CT) scans of the chest and abdomen (stomach area) and/or a magnetic resonance imaging (MRI) scan of the spine, if you have lesions in these areas. You will have an electrocardiogram (ECG -- a test that measures the electrical activity of the heart) and an echocardiogram or MUGA scan (echocardiogram/MUGA scan - a test to determine how well your heart is functioning by measuring its ability to pump blood). If the doctors know or suspect that VHL is affecting your eyes you will have an eye exam performed.

Your complete medical history will be recorded and you will have a physical exam, including measurement of your vital signs (blood pressure, heart rate, temperature, and breathing rate), height, and weight. You will be asked about any medications or treatments you are currently taking. Blood (about 2 teaspoons) will be drawn for routine tests. You will also be asked about your ability to perform daily activities. Women who are able to have children must have a negative blood pregnancy test.

You will be asked to complete 2 questionnaires that ask about your quality of life and your level of fatigue. It will take about 20 minutes to complete both questionnaires. The same questionnaires will then be completed 4-6 weeks later, and again at the end of treatment.

If you are found to be eligible to take part in this study, you will take sunitinib malate once a day, either with or without food. You will take the drug for 4 weeks in a row followed by 2 weeks of rest with no study drug. These 6 weeks are called a study "cycle".

Before beginning each new cycle, you will have a physical exam and your complete medical history will be recorded. Blood (about 1 teaspoon) will be drawn for routine tests. You will be asked about any drugs you have taken and any side effects you may have experienced. You will also be asked about your ability to perform daily activities.

At the end of Cycles 2 and 4, you will have CT or MRI scans to evaluate the status of your disease and eye exams may be repeated for those with known lesions on their eye(s).

You may receive treatment on this study for 24 weeks. However if you are showing benefit from the study drug, you may continue on study for an additional 24 weeks. (maximum total of 48 weeks) You will be taken off study if the disease gets worse or if intolerable side effects occur.

Once you stop treatment, you will have an end-of-study visit. At this visit, you will have a physical exam and blood (about 1 teaspoon) will be drawn for routine tests. You will be asked about any medications you have taken and any side effects you may have experienced. You will have CT or MRI scans to evaluate the status of your disease, as well as an eye exam if your eyes are affected by your disease. If you have completed at least 1 cycle of treatment on this study, and have had imaging scans in the past 28 days, you will skip the end of study evaluation and return for the 48 week follow-up visit.

You will have a follow-up visit about 48 weeks after your date of enrollment on this study. At this visit, you will have a physical exam and blood (about 1 teaspoon) will be drawn for routine tests. You will be asked about any medications you have taken and any side effects you may have experienced. You will have CT or MRI scans to evaluate the status of your disease. If your eyes are being affected by the disease, you will have a follow-up eye exam.

Once you complete the 48 week follow-up visit, you are considered off-study.

This is an investigational study. Sunitinib malate has been authorized by the FDA for research purposes only. About 28 patients will take part in this clinical research study. All will be enrolled at M. D. Anderson.

• Eligibility of patients receiving any medications or substances known to affect or with the potential to affect the activity or pharmacokinetics of SU011248/sunitinib malate as listed below will be determined following review of their case by the Principal Investigators. If possible, efforts will be made to switch motivated patients to other medications, otherwise patients will be excluded: (1) Ketoconazole, (2) Theophylline, (3) Phenobarbital, (4) Coumadin at therapeutic doses (low dose Coumadin up to 2 mg po daily for thromboprophylaxis is allowed).

• Ability to understand and the willingness to sign a written informed consent document.

Exclusion Criteria:

• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements.

• Pregnant women are excluded from this study because SU011248/sunitinib malate has the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with SU011248/sunitinib malate, breastfeeding should be discontinued if the mother is treated with SU011248/sunitinib malate.

• Known HIV-positive patients taking combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with SU011248/sunitinib malate. Appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Safety of Sunitinib Administration in Participants With Von Hippel-Lindau Syndrome (VHL)	Safety evaluation = Number of participants with treatment terminating toxicity using National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) 3.0. Early stopping rules applied when treatment terminating toxicity occurred in the first 6 week cycle. Recurring grade 3 toxicity requires dose reduction, with no more than 2 dose reductions permitted. If no improvement after 4 weeks, patient is taken off drug and off study, and the event recorded as treatment terminating toxicity.	12 weeks
Secondary	Number of VHL Lesion Complete + Partial Responses	Response of VHL lesions (number) evaluated using Response Evaluation Criteria in Solid Tumors (RECIST) of Complete Response (CR): Disappearance of all target lesions, and Partial Response (PR): At least a 30% decrease in the sum of longest diameter (LD) of target lesions, reference baseline sum LD. Progressive Disease (PD): 20% increase in LD sum and Stable Disease (SD): Insufficient shrinkage to qualify for PR nor increase to qualify for PD. Degree and timing of response in affected organs evaluated in order to determine organ specific kinetics of therapy.	Baseline to 12 months (evaluations at 6 and 12 months)
