Geneva, Switzerland, and Moscow, Russia, ?Selexis SA?and?Generium JSC?today announced that a fifth Selexis SUREtechnologyPlatform?-generated biological product has been approved for marketing. The latest approved product is a biosimilar monoclonal antibody, eculizumab, indicated for the treatment of paroxysmal nocturnal hemoglobinuria (PNH) and atypical hemolytic uremic syndrome (aHUS). Generium is the first company in the world to develop and market a biosimilar of eculizumab.

Paroxysmal nocturnal hemoglobinuria is a rare, life-threatening disease of the blood characterized by destruction of red blood cells by the complement system, a part of the body?s innate immune system. In people with PNH, eculizumab reduces both the destruction of red blood cells and need for blood transfusion. Atypical hemolytic uremic syndrome is an extremely rare, life-threatening and progressive disease that frequently has a genetic component. In most cases it is caused by chronic, uncontrolled activation of the complement system. The disease is characterized by the formation of blood clots in small blood vessels throughout the body, which can lead to stroke, heart attack, kidney failure, and death. Eculizumab significantly improves renal function in patients with aHUS.

?This biologic?s market approval in Russia represents another major milestone for Selexis,? said Igor Fisch, PhD, CEO, Selexis SA. ?There are currently more than 115 clinical programs utilizing the SUREtechnology?Platform, including nine Phase 3 programs. The increasing number of Selexis-generated research cell banks used in clinical programs, and now a fifth marketed product, validate our ongoing scientific innovation and our commitment to helping our partners address complicated and intractable diseases by developing complex protein therapeutics faster, safer and more cost efficiently.?

?The joint efforts of Russian, U.S. and Swiss scientists have made it possible to achieve significant progress in the development of high-tech medicines for the treatment of rare diseases such as a PNH and aHUS, with the economic benefits of local production,? said Dmitriy Kudlay, CEO of Generium. ?We believe working with Selexis improves the quality of our products and we are proud to take another step forward in helping the clinical community in Russia in their fight against rare diseases.?

Selexis? SUREtechnology?Platform is based on Selexis SGE^??(Selexis Genetic Elements) ? novel human DNA-based elements that control the dynamic organization of chromatin across mammalian cells. These elements increase transcription rates of transgenes by rendering the expression cassette independent of the locus of integration and thus allowing higher and more stable expression of any recombinant proteins. SUREtechnology?improves the way cells are used in the discovery, development and manufacturing of recombinant proteins.

The Selexis SURE CHO-M Cell Line? is a proprietary high-performance mammalian cell line derived from CHO-K1 cells. The genome of Selexis SURE CHO-M Cell Line has been fully sequenced and is used to characterize the sequence of the transgene, identify transgene integration loci and to document the monoclonality of cell populations. Selexis SURE CHO-M Cell Line is used for the production of therapeutic recombinant proteins and monoclonal antibodies.
