This study is being conducted in 2 parts. Phase I will involve dose escalation of subcutaneous CAMPATH (SQ) given 3 times per week in combination with weekly doses of rituximab (375mg/m2) for a maximum of 8 weeks in order to determine the maximum tolerated dose (MTD). In Phase II patients will be treated with SQ CAMPATH at the MTD plus weekly rituximab (375mg/m2)for a maximum of 8 weeks with primary objective of defining Overall Response (OR) to this combination.
