OUTLINE: This is a dose escalation, multicenter study of etoposide and doxorubicin HCl liposome. Patients receive doxorubicin HCl liposome IV over 1 hour on day 1, followed by oral etoposide for 8-14 days beginning on day 2. For patients who achieve partial or complete response, treatment repeats every 4 weeks for 1 year in the absence of disease progression or unacceptable toxicity. For patients with stable disease, treatment repeats every 4 weeks for 6 months. In the absence of dose limiting toxicity (DLT) in the first 3 patients treated, subsequent cohorts of 3-6 patients each receive doses of etoposide for more prolonged periods. After 14 days of oral etoposide, the dose of doxorubicin HCl liposome is escalated. The maximum tolerated dose is defined as the dose preceding that at which 2 of 6 patients experience DLT. Patients are followed every 3 months for 1 year, then until death.
