OUTLINE: This is an open label, nonrandomized study. Patients receive MEN-10755 as a single 15 minute intravenous infusion every 3 weeks, or upon recovery from toxicity. Doses will be escalated in decreasing rates and depending on the clinical judgement of the investigator. The MTD is the dose at which dose limiting toxicity is observed in at least 2 of 6 patients at a given dose level. Patients will be removed from the study if cardiac toxicity, disease progression, or renal, cardiac or pulmonary decline is present.
