What was measured

Clinical response was assessed by the Response Evaluation Criteria in Solid Tumors (RECIST) and reported along with a 95% confidence interval. Complete response is disappearance of all target lesions. Partial response is at least a 30% decrease in the sum of the diameters of target lesions, taking as reference the baseline sum of diameters. Progressive disease is defined as at least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum on study. And the appearance of one or more new lesions. Stable disease is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the smallest sum of diameters while on study.

Level 2 - 1 mcg/kg/Dose of Interleukin-15 (IL-15) Followed by Alemtuzumab

IL-15 for 10 doses over two weeks followed by alemtuzumab for 4 weeks IL-15 plus: Recombinant Human IL-15 (subcutaneous (s.c.) rhIL-15) by s.c. injection Monday-Friday over two weeks. alemtuzumab: Alemtuzumab three times a week for a total of 4 weeks of alemtuzumab treatment.

Level 3 - 2 mcg/kg/Dose of Interleukin 15 (IL-15) Followed by Alemtuzumab

IL-15 for 10 doses over two weeks followed by alemtuzumab for 4 weeks IL-15 plus: Recombinant Human IL-15 (subcutaneous (s.c.) rhIL-15) by s.c. injection Monday-Friday over two weeks. alemtuzumab: Alemtuzumab three times a week for a total of 4 weeks of alemtuzumab treatment.
