Study Arms:
- Rituximab (Type: EXPERIMENTAL): Subjects will receive rituximab administered at the standard dose and schedule as an initial cycle of therapy, followed by a re-evaluation at 6 months. If the neuropathy is stable or responding at 6 months, the subject will receive Cycle 2 of rituximab, followed by a re-evaluation at 12 months.~Rituximab will be given as a 375 mg/m\^2 intravenous infusion once weekly for four doses (days 1, 8, 15, and 22).

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