Ofatumumab Added to Fludarabine-Cyclophosphamide vs. Fludarabine-Cyclophosphamide Combination in Relapsed Subjects With Chronic Lymphocytic Leukemia

Official Title

A Phase III, Open Label, Randomized Trial of Ofatumumab Added to Fludarabine-Cyclophosphamide vs. Fludarabine-Cyclophosphamide Combination in Subjects With Relapsed Chronic Lymphocytic Leukemia

Summary:

The purpose of this study is to evaluate the safety and efficacy of ofatumumab added to fludarabine-cyclophosphamide in patients with relapsed Chronic Lymphocytic Leukemia.

Trial Description

Primary Outcome:

• Progression-free-survival

Secondary Outcome:

• Clinical benefit, safety, tolerability, changes in patient reported outcome measures and pharmacokinetics.

Fludarabine is currently approved for treatment of relapsed Chronic Lymphocytic Leukemia. Studies have shown that drugs in combination with fludarabine have shown more effectiveness than fludarabine alone. The addition of ofatumumab to fludarabine-cyclophosphamide combination offers potentially a more effective therapy, without additional toxicity. The objective of this study is to determine the effect of ofatumumab added to fludarabine and cyclophosphamide in patients with Chronic Lymphocytic Leukemia who have responded previously to therapy but later develop progressive disease and require additional therapy.
