AI Technical Summary

Benefits of technology

The patent text describes a new method for treating hematological malignancies, specifically by combining an Aurora kinase inhibitor and an anti-CD20 antibody. This combination therapy has been found to be effective in treating these malignancies and may even decrease the likelihood of relapse or resistance to a particular anticancer agent. The technical effect of this patent is to provide a more effective treatment regimen for hematological malignancies that combines the use of two different types of cancer treatment to achieve better results.

Problems solved by technology

However, while anti-CD20 antibodies and, in particular, rituximab, have been reported to be effective for treatment of B-cell lymphomas, such as non-Hodgkin's lymphoma, the treated patients are often subject to disease relapse.
Additionally, combinations of anticancer agents may have additive, or even synergistic, therapeutic effects.

Combination of Aurora A Kinase Specific Inhibitor (Compound III-1) and Rituximab in a Sub-Cutaneous Ly19 Lymphoma Model Grown in Female SCID Mice

Experimental Overview

[0165]This is an in vivo experiment looking at tumor volume after treatment with the combination of Compound III-1 and rituximab. Tumor growth was monitored with vernier calipers. The mean tumor volume was calculated using the formula V=W2×L / 2. When the mean tumor volume reached approximately 200 mm3, the animals were randomized into the following eight treatment groups, with each cohort made up of ten mice:

[0167]3 mg / kg Compound III-1 (qd)

[0168]10 mg / kg Compound III-1 (qd)

[0169]10 mg / kg Compound III-1 (bid)

Combination of Aurora A Kinase Specific Inhibitor (Compound III-1) and Rituximab in a Subcutaneous WSU-Luc Lymphoma Model Grown in Female SCID Mice

Experimental Overview

[0187]This is an in vivo experiment looking at tumor volume after treatment with the combination of Compound III-1 and rituximab. Tumor growth was monitored with vernier calipers. The mean tumor volume was calculated using the formula V=W2×L / 2. When the mean tumor volume reached approximately 250 mm3, the animals were randomized into the following six treatment groups, with each group made up of ten mice:

[0188]Vehicle

[0189]3 mg / kg Compound III-1 (P.O., qd)

[0190]10 mg / kg Compound III-1 (P.O., qd)

[0191]10 mg / kg rituximab (I.V., q7d)

[0192]3 mg / kg Compound III-1+10 mg / kg rituximab

[0193]10 mg / kg Compound III-1+10 mg / kg rituximab

[0194]The animals were inoculated with 4.0×106 cells from cell line WSU-DLCL2 at implant site Flank (cell suspension). Compounds were administered for 21 days, and tumor volumes were measured on day...

Combination of Aurora A Kinase Specific Inhibitor (Compound III-1) and Rituximab in a Sub-Cutaneous Primary Diffuse Large B-Cell Lymphoma Model (PHTX-22-06) Grown in Female SCID Mice

Experimental Overview

[0200]This is an in vivo experiment looking at tumor volume after treatment with the combination of Compound III-1, and rituximab. Tumor growth was monitored with vernier calipers. The mean tumor volume was calculated using the formula V=W2×L / 2. When the mean tumor volume reached approximately 200 mm3, the animals were randomized into the following six treatment groups, with each group made up of ten mice:

Abstract

The present invention relates to methods for the treatment of hematological malignancies. In particular, the invention provides methods for treatment of hematological malignancies by administering Aurora kinase inhibitors in combination with anti-CD20 antibodies.

Description

RELATED APPLICATIONS[0001]The present application claims the benefit of U.S. Provisional Application Ser. No. 61 / 203,509, filed Dec. 22, 2008 (pending), the contents of which are incorporated herein by reference.FIELD OF THE INVENTION[0002]This invention relates to methods for the treatment of hematological malignancies. In particular, the invention provides methods for treatment of hematological malignancies by administering Aurora kinase inhibitors in combination with anti-CD20 antibodies.BACKGROUND OF THE INVENTION[0003]According to the American Cancer Society, an estimated 1.4 million Americans were newly-diagnosed with cancer in 2004 and about 560,000 victims died from the disease. While medical advance have improved cancer survival rates, there is a continuing need for new and more effective treatment.[0004]Cancer is characterized by uncontrolled cell reproduction. Mitosis is a stage in the cell cycle during which a series of complex events ensure the fidelity of chromosome se...
