Study Description

Brief Summary: The purpose of the study is to investigate the safety of the investigational agent, cirmtuzumab. Cirmtuzumab is a monoclonal antibody drug designed to attach to a protein, called ROR1, on the surface of chronic lymphocytic leukemia (CLL) cells to block cell growth and survival. ROR1 is rarely expressed on healthy cells so the idea is to preferentially get rid of the cancer cells. Although there is evidence in laboratory animals that cirmtuzumab can decrease the number of CLL cells, the investigators do not know if this will work in humans. This drug will be given to humans for the first time in this study. Therefore, the goal of this study is to see if cirmtuzumab is safe and tolerated in study participants.

Detailed Description: This is a first in human, open-label single institution, Phase I dose escalation study of in patients with relapsed or refractory CLL. Treatment cycle (14 days) will consist of cirmtuzumab administered intravenously on a bi-weekly (every two weeks) schedule for a total of 4 doses. Eight dose cohorts (of 3 to 6 patients in size) plus an expansion cohort of 6 patients are planned. In the first 4 dose cohorts, there is intra-patient dose escalation to monitor for acute toxicities, such as tumor lysis syndrome. A cycle may be repeated every 14 days if the patient has at least stable disease by clinical examination (or interim response assessment) and has again met hematologic, renal, and hepatic laboratory parameters as defined in the eligibility section, and is without ongoing Grade 3 non-hematologic or Grade 4 hematologic toxicities attributable to cirmtuzumab. The total duration of study drug administration is 4 cycles. Each cycle consists of clinical and laboratory evaluation on Day 1 and safety assessments on Days 3 and 8.
