LONDON - Scenic Biotech BV has signed up Genentech as first partner for its high-throughput platform for identifying genetic modifiers that can suppress or even completely block the effect of a disease-causing mutated gene, as starting points for drug discovery and development. Under the terms of the agreement, Scenic will identify modifiers in undisclosed therapeutic areas, with Genentech, part of the Roche Group, having an option to take multiple targets into development.
