DART technology from MacroGenics consists of a proprietary,bi-specific antibody platform in which a single recombinant molecule is capableof targeting two different antigens. DART proteins can be used in redirectingthe human body's cell-destroying, immune effector cells against tumor cells.Proteins resulting from the program are highly potent and feature favorablemanufacturing properties. They can be produced with short or extended serumhalf-life, making them appropriate for a variety of applications in differentindications.
"We are very pleased to be expanding our existingrelationship with MacroGenics. Servier partnered with MacroGenics in late 2011on MGA271, a monoclonal antibody that recognizes B7-H3, a novel member of theB7 family of immune regulators. We believe bi-specific antibodies are an importantnew frontier in medicine," said Stephane Depil, M.D., Ph.D., in charge ofOncology Research & Development at Servier.
