    09/09/2005 - US biotechnology firm XOMA has granted Wyeth a non-exclusive, worldwide license for a technology used to make biologic drugs such as antibodies in bacteria instead of mammalian cells.

    Bacterial fermentation systems tend to be easier to work with and cheaper to operate than mammalian cell culture.
    XOMA's Bacterial Cell Expression (BCE) technology is used to discover and screen, as well as develop and manufacture, recombinant proteins and antibodies for commercial purposes. BCE is also a key technology used in multiple systems for high-throughput screening of antibody domains. Expression of antibodies by phage display technology, for example, depends on the expression and secretion of antibody domains from bacteria as properly folded, functional proteins.

    technology XOMA scientists were the first to demonstrate the secretion of antibody domains directly from the bacterial cells as fully functional, properly folded molecules. XOMA has received ten US patents to date relating to aspects of its BCE system, including six patents that broadly cover the secretion of immunoglobulins from bacteria, including antibody fragments such as Fab and single-chain antibodies. Corresponding overseas patents have also been granted.

    Under the agreement, Wyeth receives a license to use XOMA's technology for the development and production of recombinant proteins. Details of the initial payment and future contingent payments to XOMA were not disclosed.

    Currently, there are two antibody products in late-stage clinical testing that are manufactured using XOMA's BCE system. These are Celltech's Cimzia (certolizumab pegol or CDP-870) an anti-TNF alpha antibody fragment in development for rheumatoid arthritis and Crohn's disease, and Genentech Lucentis (ranibizumab) antibody fragment to vascular endothelial growth factor (VEGF), in trial to treat wet age-related macular degeneration (AMD), a major cause of blindness.

    XOMA Expands BCE Technology License With Crucell
    10/5/2005 9:09:01 AM

    BERKELEY, Calif., Oct 05, 2005 (BUSINESS WIRE) -- XOMA Ltd. (XOMA) today announced that it has expanded its existing non-exclusive, worldwide license to Crucell N.V. (CRXL) under XOMA's bacterial cell expression (BCE) technology to improve Crucell's position to perform phage display in the field of infectious disease with third party collaborators. Details of the license fee and future milestone and royalty payments to XOMA were not disclosed.


    "XOMA has built an in-depth infrastructure for microbial antibody production, including proprietary capabilities and a strong patent portfolio in bacterial cell expression," said John L. Castello, XOMA's chairman, president and chief executive officer. "With the growing market for antibody therapeutics and the increasing use of phage display for discovering antibodies, our BCE technology assets have become increasingly valuable. This is reflected in the expansion of Crucell's license, as well as in the increasing number of BCE licensees and development-stage products that use our technology."

    Bacterial Cell Expression Technology

    Bacterial cell expression technology (BCE) is an enabling technology used to discover and screen, as well as develop and manufacture, recombinant proteins and antibodies for commercial purposes. BCE is also an essential technology used in multiple systems for high-throughput screening of antibody domains. Expression of antibodies by phage display technology, for example, depends on the expression and secretion of antibody domains from bacteria as properly folded, functional proteins.

    XOMA scientists were the first to demonstrate the secretion of antibody domains directly from the bacterial cells as fully functional, properly folded molecules. XOMA has received ten U.S. patents to date relating to aspects of its BCE system, including six patents that broadly cover the secretion of immunoglobulins from bacteria, including antibody fragments such as Fab and single-chain antibodies. Corresponding foreign patents have also been granted. XOMA's patent estate is applicable to the practice of antibody phage display and other antibody screening applications.

    Currently, there are two antibody products in late-stage clinical testing that are manufactured using XOMA's BCE technologies. These are Celltech Group plc's CIMZIA(TM) (certolizumab pegol, CDP-870) anti-TNF alpha antibody fragment, in development for Rheumatoid Arthritis and Crohn's Disease, and Genentech Inc.'s Lucentis(TM) (ranibizumab) antibody fragment to Vascular Endothelial Growth Factor (VEGF) for wet age-related macular degeneration (AMD). There are many additional products under XOMA licenses in earlier stages of development. To date, XOMA has granted bacterial cell expression licenses to more than 35 companies.

    Crucell ontvangt € 2 miljoen euro subsidie van Ministerie van Economische Zaken voor het ontdekken van antistoffen tegen antibiotica-resistente bacteriële infecties



    Leiden, 16 september 2005. Het Nederlandse biotechnologiebedrijf Crucell N.V. (Euronext, NASDAQ: CRXL) heeft vandaag bekendgemaakt dat het een subsidie heeft ontvangen van het SenterNovem Innovation Subsidy for Collaborative Projects programma van het Ministerie van Economische Zaken, die kan oplopen tot maximaal € 2 miljoen. Hiermee wordt een gezamenlijke inspanning ondersteund die erop is gericht Crucell's MAbstract®-technologie toe te passen bij de ontdekking van antistoffen die helpen bij de toekomstige ontwikkeling van nieuwe medicijnen tegen antibiotica-resistente bacteriële infecties.

    Het aantal bacteriën dat resistent is tegen antibiotica neemt alarmerend snel toe, waardoor er jaarlijks in de Verenigde Staten en Europa meer dan 200.000 patiënten sterven aan infecties die zij hebben opgelopen in ziekenhuizen. Elk jaar krijgen bijna 2 miljoen patiënten te maken met infecties in de bloedbaan, longontsteking en huidinfecties. Dit zorgt alleen al in de Verenigde Staten jaarlijks voor 5 miljard dollar aan kosten in de gezondheidszorg.

    Crucell heeft voor dit project een netwerk van vooraanstaande onderzoeksinstituten samengebracht, waaronder Harvard Medical School in de Verenigde Staten en gespecialiseerde groepen van Nederlandse universiteiten. In de loop van het project probeert het bedrijf haar antistoftechnologie MAbstract® toe te passen in combinatie met haar vaccinatie- en productieplatforms, om de toekomstige ontwikkeling van medicijnen tegen antibiotica-resistente bacteriën te ondersteunen. MAbstract® is een technologie die kan worden gebruikt om zogenaamde 'drug targets' te identificeren, zoals eiwitten uit ziekteverwekkers als bacteriën en virussen, en om menselijke antistoffen tegen die 'drug targets' te vinden.

    "Naarmate ons vaccin- en antistofprogramma vordert, krijgen we steeds meer kennis en ervaring op het gebied van onze belangrijkste technologieën," vertelt Dr. Jaap Goudsmit, Chief Scientific Officer van Crucell. "We zijn trots dat we deze expertise nu kunnen toepassen ter bestrijding van de medicijn-resistente bacteriële ziekten die een groot probleem vormen in ziekenhuisomgevingen."

    Dit stelt Crucell in staat om zijn Mabstract technologie te blijven gebruiken om nieuwe antilichamen te vinden/maken.
    Wat de uitbreiding inhoudt zou ik wel willen weten.
    Misschien o.a. samen met DSM antibiotica-resistente bacteriële infecties te lijf gaan ?
