Summary

This study will examine the safety and effectiveness of the experimental drug bevacizumab for treating both non-acquired immune deficiency syndrome (AIDS) and AIDS-associated Kaposi's sarcoma (KS). KS tumors depend on the formation of new blood vessels for their growth. Bevacizumab is an antibody to a protein called vascular endothelial growth factor (VEGF) that is produced by the body and is involved in blood vessel growth. Bevacizumab may block the action of VEGF, and thus help shrink KS lesions.

Patients 18 years of age and older with Kaposi's sarcoma that is restricted to the skin and is not life threatening may be eligible for this study. Candidates will be screened with a medical history and physical examination, blood and urine tests, electrocardiogram (EKG), chest x-ray, and, if needed, imaging studies to evaluate internal tumors.

Participants will receive bevacizumab intravenously (by vein) once a week for 2 weeks and then every 3 weeks at the National Institutes of Health (NIH) Clinical Center. The first infusion takes about 90 minutes, the second takes about 60 minutes, and subsequent infusions take about 30 minutes. Infusions may take longer, however, if the drug is better tolerated at a slower infusion rate. Patients will be evaluated with the following tests and procedures:

* Physical examination, assessment of drug side effects, measurement of KS lesions, and photographs of lesions once a week for the first 6 weeks of therapy, and then every 3 weeks.
* cluster of differentiation 4 (CD4) cell counts and human immunodeficiency virus (HIV) viral load in HIV-positive patients every 12 weeks.
* Biopsies of lesions: upon entering the study, at week 12, and at the time of a response of the tumor to therapy or at the end of treatment, if treatment ends at week 18 or later.
* Additional biopsies, if requested. (Additional biopsies are not required.)
* Other procedures, such as computed tomography (CT) or magnetic resonance imaging (MRI) scans, if medically indicated.

Patients may continue bevacizumab therapy indefinitely if they are benefiting from it, as long as they have no substantial toxicity or other conditions that would cause them to stop receiving it and the protocol remains open.
