What was measured

The eCRF Hematology data (specifically white blood cell count (WBC)) for each timepoint will be used to derive the Cell counts in 10\^9/L. Once merged with the pharmacodynamic data by subject and timepoint, the following will be used as derivation: • Ki-67+ Cells of CD3-CD56+ (NK) Cells (10\^9/L) = Ki-67+ Cells of CD3-CD56+ (NK) Cells (%CD45+) x 0.01 x WBC Absolute count of Ki-67+ Cells was calculated as percentage of those cells out of CD45+ multiplied by WBC and 0.01.

Analysis population: For several patients the PD profile was not evaluable: 7 patients in part A (1 in 0.25 μg/kg, 1 in 6 μg/kg, 2 in12 μg/kg and 3 in 15 μg/kg arms), 2 patients in Part A1 (1 in 9 μg/kg and 1 in 12 μg/kg arms), 5 patients in Part B (3 in 6 μg/kg, 1 in 9 μg/kg, and 1 in 12 μg/kg arm), and 37 patients in Part D.

description
The eCRF Hematology data (specifically white blood cell count (WBC)) for each timepoint will be used to derive the Cell counts in 10\^9/L. Once merged with the pharmacodynamic data by subject and timepoint, the following will be used as derivation: • Ki-67+ Cells of CD3-CD56+ (NK) Cells (10\^9/L) = Ki-67+ Cells of CD3-CD56+ (NK) Cells (%CD45+) x 0.01 x WBC Absolute count of Ki-67+ Cells was calculated as percentage of those cells out of CD45+ multiplied by WBC and 0.01.
