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.

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.

Paras Biopharmaceuticals Finland Oy has successfully achieved a very high expression of PB (RA)- 2010.
