What was measured

This study is a series of 3 single-arm phase-I trials designed to determine the maximum tolerated dose (MTD) of a 2-cycle combination regimen containing Rituxan + Y2B8 radioimmunotherapy with and without the use of G-CSF and IL-11. Trial 1 will determine the Y2B8 MTD in the combined regimen without growth factors. Trial 2 will evaluate the combined regimen with growth factors. Trial 3 starts IL-11 earlier (when platelet count drops below 150000) and reduces the dosing interval to twice weekly. \> Dose-limiting toxicity (DLT) is defined as an adverse event in the second cycle attributed to treatment and meeting the following criteria: Grade 4 ANC or platelet decrease for 14 days, or grade 3 for 28 days, or any other grade 3 Non-Heme event. \> If at any time 2 or more patients (of a maximum of 6) at any dose level experience DLT, then the MTD will be defined as the previous dose level during that trial. The number of patients with a DLT are reported here.

Analysis population: DLTs were determined in the second cycle of combined treatment. Only Phase I patients that were evaluated after 2 cycles of treatment are included in this evaluation. Two patients at Dose Level 1, 1 patient at Dose Level 2, 4 patients at Dose Level 3, and 1 patient at Dose Level 5 were not evaluated for MTD.
