Pharming acquires licences to key fibrinogen patents

LEIDEN, NETHERLANDS--(Marketwire - June 25, 2008) -


Important step for recombinant fibrinogen and biomaterials program

Leiden, The Netherlands, June 25, 2008. Biotech company Pharming Group NV ("Pharming" or "the Company") (NYSE Euronext: PHARM) announced today that it has acquired an exclusive sub-license to key patents and technology on recombinant fibrinogen from GTC Biotherapeutics Inc ("GTC"). These rights enable Pharming to accelerate pharmaceutical development of recombinant human fibrinogen (rhFIB) and stimulate medical device development through its biomaterials program.

Pharming has obtained exclusive licenses on recombinant fibrinogen for all indications in various territories, including North America, Europe and Japan. The licenses are to recently issued patents owned by the American Red Cross, Virginia Tech Intellectual Properties Inc and the University of North Carolina on the production of recombinant fibrinogen in milk of transgenic animals which are licensed to GTC from ProGenetics, LLC. The license agreement includes an upfront payment to GTC of approximately EUR 350,000 (US$ 550,000) and a royalty on commercial sales of rhFIB. Pharming already owns several additional patents and licenses for recombinant fibrinogen and recombinant tissue sealant compositions. The acquisition of the license from GTC further broadens and strengthens Pharming's position in this field.

Pharming has a development program for recombinant human fibrinogen as a replacement therapy for genetic and acquired deficiencies of fibrinogen. The existing market size for fibrinogen deficiencies is estimated to be over USD 500 million in the developed world. In addition to the deficiency market, rhFIB has the potential as a pharmaceutical product to address the significantly larger market of traumatic and surgical bleeding in excess of USD 1 billion. Current standard of care in the US for patients deficient in fibrinogen is the use of cryoprecipitate, which is composed mainly of plasma derived fibrinogen. In certain European countries, a partially purified plasma fibrinogen product is marketed.

Pharming has successfully produced high levels of rhFIB using its production technology. This was a technical breakthrough given the biochemical complexity of the fibrinogen molecule consisting of several subunits folded together in fixed ratios. In laboratory tests and initial animal studies, rhFIB has been demonstrated to be virtually identical in structure and function to plasma fibrinogen.

Bruno Giannetti, Chief Operations Officer, commented: "Securing the patent rights is important for the development of recombinant human fibrinogen, a key part of our product portfolio. We can now accelerate development of our fibrinogen product for pharmaceutical use and establish partnerships for medical device development. Pharming has already provided rhFIB for evaluation to several device manufacturers and research institutions to facilitate novel product development for various applications. Over the last few years, the Company has been building a program on biomaterials through collaborations with the BioMedical Materials consortium (BMM) in The Netherlands, NovaThera Ltd, the US Army and other institutions."

About recombinant human fibrinogen (rhFIB)

Human fibrinogen is a natural human plasma protein involved in blot clotting. Deficiency or low levels of fibrinogen can result in uncontrolled bleeding, as can occur in case of trauma, surgery, liver disease, sepsis and cancer. Pharming is developing recombinant human fibrinogen (rhFIB) as a replacement therapy for patients with genetic and acquired deficiencies of fibrinogen. The existing market size for fibrinogen deficiencies is estimated to be over USD 500 million in the developed world. In addition to the deficiency market, rhFIB has the potential as a pharmaceutical product to address the significantly larger market of traumatic and surgical bleeding in excess of USD 1 billion. In addition to pharmaceutical development of rhFib, Pharming will pursue partnerships with medical device manufacturers on rhFIB to build further value for its biomaterial portfolio.
