Rheumatoid Arthritis - API Product PB (RA) - 2010 & Biosimilars Technology

PB-RA-2010 is soon to be off patent involving biosimilars API / biosimilars technology for the production of recombinant human Interleukin-I receptor-antagonist protein. The product is used for the treatment of Rheumatoid Arthritis (RA). PB-RA-2010 is a biosimilars molecule that works as part of a group of recombinant products by blocking the biological activity of the IL-I receptor. IL-I is a key mediator of inflammation and a driver of auto inflammatory diseases in both adults and children.

PB-RA-2010 is a recombinant non-glycosylated version of IL-IRA produced in genetically modified E. Coli using recombinant DNA technology. It consists of 153 a.a. and possesses a molecular mass of 17.3 KDa. As a biosimilar, it is an approved therapy for RA.

Paras Biopharmaceuticals Finland Oy has successfully achieved a very high expression of the Biosimilar Rheumatoid Arthritis product.
