AUSTIN, Texas, July 15, 2011 /PRNewswire/ --

- Le brevet de composition de matières couvre les applications thérapeutiques et diagnostiques élargies

Convergen LifeSciences Inc. a annoncée aujourd'hui qu'un autre brevet américain 7,977,468 a été décerné par le Bureau américain des brevets et des marques de commerce à The University of Texas System Board of Regents et au Secrétaire à la Santé et aux services sociaux des États-Unis. Le brevet (patent) est l'un des 23 brevets, en instance ou émis dans le monde, sous licence exclusive de Convergen LifeSciences, Inc. Le brevet s'applique au CNVN202, une thérapie moléculaire ciblée du cancer soumise à une analyse clinique chez les patients atteints d'un cancer du poumon.

Le brevet '468 repose sur d'importantes découvertes faites par une équipe de chercheurs du Centre de recherche sur le cancer M.D. Anderson de l'Université du Texas (The University of Texas MD Anderson Cancer Center), le The University of Texas Southwestern Medical Center et le National Cancer Institute. La découverte de la famille de gènes suppresseurs de tumeur 3p21.3 a fait l'objet de plus de 20 publications dans des revues scientifiques démontrant la capacité des gènes à contrôler les mécanismes clés anticancéreux. Le CNVN202 exploite le TUSC2 (FUS1), le plus puissant inducteur de l'apoptose dans la famille des gènes suppresseurs de cancer 3p21.3.

« Le brevet prouve le bien-fondé de notre portefeuille de propriété intellectuelle », a indiqué Greg Heinlein, directeur de l'exploitation et financier de Convergen LifeSciences. « Dans l'ensemble, ce brevet élargit l'application du CNVN202 à pratiquement tous les cancers et l'utilisation de nos technologies brevetées afin d'inclure des outils de dépistage et de diagnostic du cancer. »

Les données recueillies lors de la phase 1 de l'essai clinique présentées à la réunion annuelle 2011 de l'Association américaine pour la recherche contre le cancer ont démontré pour la première fois qu'un gène suppresseur de tumeur peut être administré par voie intraveineuse et de façon sélective pour les cellules cancéreuses humaines en utilisant un vecteur nanoparticulaire, en exprimant des niveaux élevés d'ARNm et de protéines dans les cellules cancéreuses des sites métastatiques primaires et lointains, et en modifiant les trajectoires pertinentes dans la cellule cancéreuse et en médiant l'activité clinique anticancéreuse bénéfique.

La phase II de l'essai clinique est prévue afin d'analyser le CNVN202 en combinaison avec le Tarceva® (erlotinib) chez les patients souffrant d'un cancer du poumon, qui ne ressentirait pas l'effet favorable de l'erlotinib seul. Le CNVN202 a démontré une synergie en combinaison avec l'erlotinib à la fois pour les mutations EGFR positives et négatives des cancers.

Tarceva® est une marque de commerce déposée de Roche Group y compris Genentech et Chugai et Astellas Pharma.
