Brief Summary

To examine the safety and efficacy of two doses of vesnarinone in patients with AIDS-related Kaposi's sarcoma.

Detailed Description

Twenty-eight patients (14 per cohort) receive daily vesnarinone at one of two doses. At least seven patients at the lower dose must have completed 2 weeks of therapy before subsequent patients are entered at the higher dose. Patients who successfully complete 16 weeks of treatment may receive maintenance therapy for the duration of the study (approximately 12-18 months).
