Clinical Protocol for the Treatment of Patients With Previously Untreated Chronic Lymphocytic Leukemia With a Combination of Bendamustine and Ofatumumab

Study Overview
=================
Brief Summary
-----------------
Investigational Drug: Ofatumumab (Azerra) Route of Administration: Intravenous (IV) Hypothesis: This study is designed to assess the toxicity and overall response rate. Ofatumumab is a fully human monoclonal antibody (A type of protein made in the laboratory that can bind to substances in the body, including tumor cells) that shows promising activity in the treatment of CLL as a single agent. It is thought that by combining it with Bendamustine, an FDA approved treatment for CLL, the effect on CLL will be greater than if Ofatumumab is given alone. Participation: Approximately 38 previously untreated CLL subjects will participate in this study over two years. Treatment Plan: A maximum of 6 cycles of treatment will be allowed. During day 1 of cycle 1 ofatumumab IV 300mg will be administered. On day 1 of all cycles ofatumumab treatment will be followed by bendamustine IV 90mg/m2. On day 2 of all cycles, bendamustine IV 90mg/m2 will be administered. On day 3 of all cycles, neulasta SQ 6mg will be given. On day 8 of cycle 1 only patients will receive ofatumumab IV 1000mg. During cycles 2 through 6 ofatumumab 1000mg will be given on day 1 only. Follow-up: Patients will be followed monthly for six months, then every three months for five years then annually thereafter.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Overall Response Rate (Efficacy) | The primary objective for this study is to evaluate the overall response rate of bendamustine and ofatumumab in patients with previously untreated CLL. |  | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Safety Evaluation | 1) evaluating the toxicity of patients treated with bendamustine and ofatumumab |  | 
| Response Rate Evaluation | evaluate complete response rate, progression- free survival, overall survival, and time to next therapy |  | 
| Correlative Analysis | determine whether the expression of ZAP-70, CD38, IgVH status, and chromosomes, correlate with response rate, duration of response, and survival. |  |
