A Phase I/II, a Single Arm, Open-label Study of Ofatumumab (GSK1841157) in Patients With Previously Treated Chronic Lymphocytic Leukemia

2014-08-27 03:15:35 | BioPortfolio

Summary

Ofatumumab is an IgG1κ fully human monoclonal antibody (mAb) that specifically recognizes an epitope on the human differentiation antigen CD20 molecule. In vitro and in vivo studies demonstrated that ofatumumab depletes CD20 positive (CD20+) B cells through complement-dependent cytotoxicity (CDC) and antibody-dependent cell-mediated cytotoxicity (ADCC), which results in the antitumour effect.

This is an open-label study to evaluate safety, tolerability, efficacy and PK profile of ofatumumab monotherapy in chronic lymphocytic leukemia (CLL) patients. Ofatumumab will be administered intravenously at the first dose of 300mg followed by 7 weekly infusions of 2000mg, followed by 4 infusions of 2000mg at every 4 weeks.

Primary objective of the study (Part A) is to evaluate tolerability, and the study (Part B) is to assess overall response rate in CLL population.

10 subjects will be enrolled into this study. Subjects will be followed for 48 weeks.

Medical and Biotech [MESH] Definitions

A chronic leukemia characterized by abnormal B-lymphocytes and often generalized lymphadenopathy. In patients presenting predominately with blood and bone marrow involvement it is called chronic lymphocytic leukemia (CLL); in those predominately with enlarged lymph nodes it is called small lymphocytic lymphoma. These terms represent spectrums of the same disease.

Inflammatory diseases of the THYROID GLAND. Thyroiditis can be classified into acute (THYROIDITIS, SUPPURATIVE), subacute (granulomatous and lymphocytic), chronic fibrous (Riedel's), chronic lymphocytic (HASHIMOTO DISEASE), transient (POSTPARTUM THYROIDITIS), and other AUTOIMMUNE THYROIDITIS subtypes.

A chronic leukemia characterized by a large number of circulating prolymphocytes. It can arise spontaneously or as a consequence of transformation of CHRONIC LYMPHOCYTIC LEUKEMIA.

A nitrogen mustard alkylating agent used as antineoplastic for chronic lymphocytic leukemia, Hodgkin's disease, and others. Although it is less toxic than most other nitrogen mustards, it has been listed as a known carcinogen in the Fourth Annual Report on Carcinogens (NTP 85-002, 1985). (Merck Index, 11th ed)
