Study Requirements

Study subjects will have a screening visit within 28 days of starting treatment. This visit includes a x-ray, MRI, CT, PET/CT, bone marrow and/or lymph node biopsies to assess disease status and response if not done in the previous 3 months. In addition to clinically indicated labs subjects will be asked to give an additional blood sample: approximately 2.5 tablespoons for Cycle 1, 1.5 tablespoons for Cycle 2, and 1 tablespoon for Cycle 3. Subjects can remain on trial for up to 35 cycles (approximately 2 years), or unacceptable toxicities, or disease progression occurs.
