Mediar Therapeutics Inc. emerged from stealth, unveiling $105 million in investment and bold ambitions to develop new ways of tackling fibrosis. Cambridge, Mass.-based Mediar is challenging what CEO Rahul Ballal called “the fundamental dogma” of fibrosis therapy: “You have to address fibrosis at its initiation, when inflammation is rampant.” Mediar, in contrast, is focused on developing therapies that either disrupt or reverse the fibrotic process, particularly when it progresses from a moderate to a severe state.
