Phase II Study of Vandetanib in Individuals With Kidney Cancer
This study will examine the effectiveness of an investigational drug called ZD6474 (also known as vandetanib or ZACTIMA). Vandetanib is an experimental drug that is designed to prevent the growth and development of new blood vessels on tumors and to prevent the direct growth of cancer cells. It has been tested in a number of clinical trials on adults with cancer, but the United States (U.S.) Food and Drug Administration has not specifically approved it as a cancer treatment. The purpose of this investigational study is to better understand how vandetanib affects humans who have kidney cancer related to von Hippel-Lindau (VHL) disease, and to develop tests that may improve researchers understanding of kidney cancer and its effects.
Volunteers must be at least 18 years old and must have been diagnosed with kidney cancer related to VHL. Candidates must have a life expectancy greater than three months and must have at least one measurable renal tumor for study purposes. Candidates may not be receiving any other investigational agents or have been treated with an investigational drug within the past four weeks. Candidates who have had surgery, chemotherapy, or radiotherapy within the past four weeks will be excluded from the study. Candidates will be screened with a physical examination and medical history.
During the study, participants will receive an oral dose of vandetanib once a day for 28 days (a treatment period known as a cycle). Participants will need to return to the National Institutes of Health every two weeks on the same day of the week as the first dose of vandetanib for a series of tests and procedures, including blood and urine tests and an electrocardiogram. Every 12 weeks, computerized tomography (CT) or magnetic resonance imaging (MRI) scans will be done to assess the size of participants tumors. Participants whose tumors do not grow and who do not have unacceptable side effects may continue to receive vandetanib to maintain the current condition, until researchers conclude the study....

- Overall Response Rate. [ Time Frame: cycle 3, day 28 ] [ Designated as safety issue: No ]Overall response rate is defined as the percentage of participants with either a partial or complete response occurring at any time after initiation of therapy. Response is determined by the Response Evaluation Criteria in Solid Tumors (RECIST). Partial response (PR) is at least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as reference the baseline sum LD. Complete response (CR) is a disappearance of all target lesions. Progressive disease (PD) is at least a 20% increase in the sum of the LD of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. Stable disease (SD) is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD (progressive disease), taking as reference the smallest sum LD since the treatment started.
- Number of Participants With Adverse Events [ Time Frame: 72 months and 14 days ] [ Designated as safety issue: Yes ]Here is the number of participants with adverse events. For a detailed list of adverse events, see the adverse event module.
