The Humanized Monoclonal Antibody Milatuzumab for Refractory Chronic Lymphocytic Leukemia (CLL)

June 1, 2010 updated by: Kaplan Medical Center

Phase I-II Trial of the Anti CD74 Monoclonal Antibody-Milatuzumab as a Single Agent in Refractory Chronic Lymphocytic Leukemia

The purpose of this study is to determine whether Milatuzumab is effective in patients with refractory chronic lymphocytic leukemia, and also to find out in which range of doses is a response seen.

Detailed Description

The aim of this study is to determine whether the anti-CD74 monoclonal antibody Milatuzumab provides benefit to subjects with CLL in advanced stage or progressive disease. The primary objectives of this study are to assess response rate to the agent, as well as the safety in CLL, using different doses: Overall response (OR), complete response (CR) and partial response (PR) will be determinate according to the NCI criteria.

The secondary objectives are to determine: duration of response, time to progression, overall survival, and the range of doses in which efficacy is seen and MTD not reached.

This study will be done in parallel with other phase I-II studies conducted by Immunomedics.

The study design will take into account that the high levels of circulating CD74expressing cells in CLL may affect both the acute (although probably not long term) toxicity and the efficacy of the study medication. This could translate to a different MTD and a different cumulative dose of Milatuzumab, needed to achieve response.(either a higher dose or longer treatment period.).

The study will be divided into two treatment phases. In the first phase we aim to address whether the dose of 120 mg/m2 is effective in CLL, and also if it is safe. In the second phase we will assess the safety and possible efficacy of higher doses, in those patients that did not achieve a significant response in the first phase. This will be done by gradual dose escalations, not to exceed 600 mg, or the MTD reached in other studies.

In addition, the study will aim at gaining further understanding of the effect of Milatuzumab on the biological in-vitro function of CLL cells.
