POTELIGEO is a humanized monoclonal antibody produced by applying POTELLIGENT technology which was developed exclusively by Kyowa Hakko Kirin. This product is the first antibody for which Kyowa Hakko Kirin has an NDA approved, and is also the world’s first POTELLIGENT antibody approved for marketing approval. POTELIGEO binds to CCR4 that is expressed on the surface of ATL cells. POTELIGEO was also granted an orphan drug designation for the treatment of CCR4-positive ATL by the Ministry of Health, Labour and Welfare.

Kyowa Hakko Kirin is working to provide treatment for a wide range of diseases with an unmet medical need including orphan diseases such as ATL. Kyowa Hakko Kirin will strive to contribute to the improvement of patients’ QOL through the development of therapeutic antibodies using its unique antibody technologies.

About Adult T-cell leukemia-lymphoma (ATL)
HTLV-1 (retrovirus)-induced peripheral T-cell lymphoma. Currently, about 1150 people a year develop ATL in Japan. Generally, combination chemotherapy such as mLSG15 is used, but no curative treatment has been established for ATL, except transplantation, which is actively being studied at present. For recurrent/relapsed ATL, different types of chemotherapies are used based on the treatment of malignant lymphoma, but no effective treatment has been established.

About POTELLIGENT
Kyowa Hakko Kirin’s unique technology to produce antibodies with enhanced ADCC activity. This technique allows production of antibodies that reduces the amount of fucose in the carbohydrate structure of an antibody. Non-clinical studies have confirmed that antibodies produced by this technology killed the target cells much more efficiently than existing antibodies and exhibited stronger antitumor effects.

About CCR4 (chemokine [C-C motif] receptor 4)
CCR4 is one of chemokine receptors involved in leukocyte migration. It is known that in normal cells, CCR4 is selectively expressed in type 2 helper T (Th2) cells that produce cytokines such as IL-4 and IL-5 (CD4-positive). It is also known that CCR4 is highly expressed in certain hematological malignancies.

About ADCC (antibody-dependent cellular cytotoxicity)
When an antibody binds to an antigen, effector cells such as macrophages and NK cells subsequently bind to the antibody. Antigen-bearing target cells are killed by these effector cells.

Patrys Granted Key Patent for Lead Product PAT-SM6

On May 24, 2012 Patrys reported that it has just been granted a U.S. patent for lead product PAT-SM6 (Press release Patrys, MAY 24, 2012, View Source [SID:1234500549]).
The patent granted by the U.S. Patent Office as US 8,124,080 contains claims that cover the PAT-SM6 antibody binding to low-density lipoprotein (LDL) and components of LDL which are believed to be involved in the mode of action for the product.
