Objective
- To map the existence and status of pending patent applications and patents filed in Russia (either directly at the Russian patent office or via the Eurasian Patent Office) that are directed at anti-TNFalpha antibodies, including antibodies such as infliximab (Remicade), adalimumab (Humira), certolizumab pegol (Cimzia), and golimumab (Simponi), and their uses.
Background
Tumor necrosis factor
Tumor necrosis factor is a cytokine involved in systemic inflammation and is a member of a group of cytokines that stimulate the acute phase reaction. The primary role of TNF is in the regulation of immune cells. TNF is also able to induce apoptotic cell death, to induce inflammation, and to inhibit tumorigenesis and viral replication. Dysregulation of TNF production has been implicated in a variety of human diseases, as well as cancer Soruce TNF is critically involved in the pathogenesis of several chronic inflammatory diseases. Monoclonal antibodies against TNF are currently used for the treatment of rheumatoid arthritis and Crohn's disease. Dalum et al., 1999
Anti-TNF antibody
Monoclonal antibodies to tumor necrosis factor alpha (TNF-alpha) and soluble receptor complexes comprising the extramembrane portion of the TNF receptor coupled with the Fc portion of the human IgG1 molecule have been utilized as therapies for severe sepsis and septic shock. Abraham, 2004 A review about TNF-α, based on 78 published articles, using TNF-α antibody is summarized here
Since tumor necrosis factor (TNF) plays an important role in host defense and tumor growth control. Therefore, anti-TNF antibody therapies may increase the risk of serious infections and malignancies. To assess the extent to which anti-TNF antibody therapies may increase the risk of serious infections and malignancies in patients with rheumatoid arthritis a study has been conducted by Bongartz et al., 2006
Search strategy
To capture the Russian patents a 3 way search strategy was built:
- Micropatent full text searches on English patents and then taking out Russian family members from the on target English patents
- Searching patents with keywords and class codes having country code RU (Russia) and EA (Eurasia) in Micropatent INPADOC
- Searching for patents in Eurasian patent office and Russian patent office, individually, with class codes and keywords
Micropatent full text search
Search logic: To first search for all English patents (such as US, WO, EP etc.) with keywords given below and then filter out patents which have Russian family members.
