NOTE: hu14.18K322A infusion over 4 hours unless rate decreased secondary to toxicity.

a

GM-CSF 250 mcg/m2/day s.q., day 7 through the nadir until ANC > 2,000/mm3; IL2 1 million units/m2 s.q. every other day for six doses (day 6, 8, 10, 12, 14, and 16).

b

GM-CSF 250 mcg/m2/day s.q., day 8 through the nadir until ANC > 2,000/mm3; IL2 1million units/m2 s.q. every other day for six doses (day 7, 9, 11, 13, 15, and 17). GM-CSF and IL2 start 1 day later in cycles 3 and 4 due to a delay in the NK-cell infusion to ensure that at least two half-lives of the active metabolite of irinotecan, SN-38, have elapsed.
