Multi-center, open-label, single-dose, dose-escalating Phase I/II study of GS 9219 in adult patients with relapsed or refractory CLL, NHL or MM. Patients will be enrolled into the study in sequential dose cohorts. Patients will be administered a single IV infusion of GS 9219 on Day 1 of a 21 day cycle and may receive a total of six treatment cycles based on toxicities and response. Patients who demonstrate disease progression will be discontinued from the study. Patients who, at the completion of six treatment cycles, tolerate treatment and show evidence of disease control (response or stabilization) will be eligible to continue receiving treatment at the same dose.
The primary objective of this study is as follows: To assess the safety, toxicity, and maximum tolerated dose (MTD) of GS 9219 administered via IV administration once every three weeks (21 days) for six treatment cycles, i.e. for a total of 18 weeks, in patients with relapsed or refractory Chronic Lymphocytic Leukemia (CLL), Non-Hodgkin's Lymphoma (NHL) or Multiple Myeloma (MM). The secondary objectives of this study are as follows: To determine the pharmacokinetic parameters of GS 9219 for this regimen and patient population. To assess the antitumor activity of GS 9219 based on Response Rate and Duration of Response. Progression-free Survival and Overall Survival will be assessed if applicable.

Determination of MTD
Toxicity will be graded according to the NCI Common Terminology Criteria for Adverse Events (CTCAE). The MTD will be the highest dose level immediately below the dose level where two or more of three to six patients experience a dose-limiting toxicity (DLT).
