A Phase I Safety, PK and PD Study of KW-2478 in Patients With Multiple Myeloma, Chronic Lymphocytic Leukaemia or B-cell Non-Hodgkin's Lymphoma

A Phase I, Open-Label, Dose-escalation, Multicentre Study of KW-2478 Administered as a Single Agent Intravenously in a Consecutive Dosing Schedule in Patients With Relapsed/Refractory Multiple Myeloma, Chronic Lymphocytic Leukaemia or B-cell Non-Hodgkin's Lymphoma

The aim of this study is to determine the safety, tolerability and dose-limiting toxicities of KW-2478 and to determine the Maximum Tolerated Dose and recommended Phase II dose for patients with relapsed/refractory MM, CLL or B-cell NHL.

This is a Phase I, open-label, dose-escalation study of KW-2478 in patients with relapsed/refractory multiple myeloma, chronic lymphocytic leukaemia or B-cell Non-Hodgkin's lymphoma who have no established therapeutic alternatives. Up to 42 patients will be enrolled at up to six investigational sites over a period of approximately 12 months until an MTD is reached. An additional 12 patients may be enrolled at the MTD in an expanded cohort of one or more of the eligible conditions.

Inclusion Criteria:

1. Patients with a confirmed diagnosis of Multiple Myeloma, Chronic Lymphocytic Leukaemia, or B-cell Non-Hodgkin's Lymphoma, who have had at least two prior standard treatment regimens and are without established therapeutic alternatives.
2. Signed IEC-approved informed consent
3. ECOG performance status of 0, 1 or 2;
4. Life expectancy of at least 3 months;
5. Adequate haematologic status, liver function and renal function
6. Patients of reproductive potential must agree to follow accepted birth control methods during the study

Exclusion Criteria:

1. No anti-cancer treatment for ≥ 3 weeks prior to receiving study drug
2. Any other severe, acute or chronic illness
3. No other prior or concurrent malignancy
4. Immunosuppressant therapy
