The « Paris Biotech Vallée » cluster spans from Villejuif to Evry. According to the Greater Paris Region master plan 2030 (Schéma directeur de la Région Ile-de-France, or SDRIF), the cluster starts at Institut Gustave Roussy in Villejuif and spreads up to the Kremlin-Bicêtre plateau dedicated to healthcare and science. Its objective is the emergence of an international reference hub in areas such as healthcare R&D and the fight against cancer. Covering about 70 hectares, its perimeter includes the Cœur d’Orly project.
Spanning from Villejuif (Val-de-Marne) to Evry (Essonne), Paris Biotech Vallée is the largest of the seven Grand Paris clusters. While the concentration around life sciences is stronger in Val-de-Marne, this cluster develops as far as Essonne through healthcare and other more general projects.
