The ether lipid miltefosine (hexadecylphosphocholine) was orally given to patients with various tumours in a dose-finding study. All patients initially received a daily total dose of 100 mg, which in the absence of side-effects was increased to 150 mg and further to 200 mg. A total of 54 patients were entered and were evaluable for gastrointestinal toxicity. Nausea and vomiting were found to be dose-limiting; 22% of patients ultimately tolerated a dose of 100 mg, 59% tolerated a dose of 150 mg and 19% tolerated a dose of 200 mg. In addition 30% of patients developed renal dysfunction, which was thought to be related to the drug. No other toxities were observed. For further phase II studies it is recommended that one starts with a dose of 150 mg daily, divided over three administrations.
