Lintuzumab-Ac225BIOLOGICALIn Phase 1 the starting dose level was 1.0 μCi/Kg of Lintuzumab-Ac225 and 15 μg/Kg unlabeled HuM195 divided into 2 equal fractionated doses (0.5 μCi/Kg and 7.5 μg /Kg + 0.5 μCi/Kg and 7.5 μg /Kg) with the first fraction administered approximately 4-7 days after 1 cycle of low dose cytarabine and the second fraction administered 4-7 days after the first fraction, followed by up to 11 more cycles. In Phase 2 the dose will be 4.0 μCi/Kg Lintuzumab-Ac225 and 25 μg/Kg unlabeled HuM195 divided into 2 equal fractions with the first fraction given on Day 1 and the second fraction given on Day 5-8.
