Phase I trial of elactocin

Elactocin is a novel anti-tumour antibiotic which has potent activity in vitro against a range of tumours. This phase I trial of elactocin identified the dose-limiting toxicity as profound anorexia and malaise. The schedules used included 1 h infusion 3 weekly, 24 h infusion 3 weekly, 1 h infusion daily x 5 (3 weekly), 1 h infusion weekly and finally continuous 5 day intravenous infusion. On all these schedules dose-limiting toxicity was the same and as no partial or complete responses were identified, we do not recommend that further trials of elactocin are performed.
