Study Arms:
- Phase I (Type: EXPERIMENTAL): Phase I portion of the study, a standard 3+3 dose escalation schema will be followed. Patients will receive veltuzumab IV weekly on day 1 for 4 doses and milatuzumab weekly on for 4 total doses during induction therapy. Induction therapy will be defined as the first 4 weeks of study therapy. During week 1 of induction therapy, patients will receive veltuzumab alone on day 1 and milatuzumab alone on day 2 to prevent overlapping infusion reactions. Starting week 2, veltuzumab will be given on day 1 and milatuzumab will be given on day 4.
- Phase II (Type: EXPERIMENTAL): Patients will receive veltuzumab IV weekly for 4 doses and milatuzumab IV weekly on day 2 of week 1 and on day 4 of weeks 2-4 for 4 total doses during induction therapy. Patients may continue on therapy to receive extended induction therapy provided they do not experience significant toxicity or rapid disease progression during the initial 4 week induction.

Based on this trial design, predict the completion outcome and termination type (if applicable).
