A Phase I Study of TNP-470 in the Treatment of AIDS-Associated Kaposi's Sarcoma

Since evidence shows that neovascularization is important in the development of Kaposi's sarcoma, drugs that inhibit angiogenesis, such as TNP-470, may be of benefit in patients with the disease. Patients are entered at 7 escalating dose levels of TNP-470. (PER AMENDMENT 9/3/96: dose maximum level changed.) Four patients treated at a given dose level must receive at least 4 weeks of therapy before escalation in subsequent cohorts proceeds. If 50 percent of patients at a given dose level experience dose-limiting toxicity, the previous dose is defined as the MTD and an additional two patients are treated at the MTD. Patients receive treatment for 12 weeks, followed by 2 weeks of rest, followed by an additional 12 weeks of treatment. Patients are followed for 12 weeks post-treatment.
