MedDay is a French biotech company in the treatment of neuro-metabolic diseases. Founded in 2011 by Frédéric Sedel and Guillaume Brion, MedDay relies on the work of Dr Frédéric Sedel, a neuroscientist at La Pitié Salpêtrière Hospital (Paris), who has been carrying out pioneering research in neurology to identify rare hereditary metabolic diseases in adults for more than a decade. Dr Frédéric Sedel’s research has led to the identification of new treatments and diagnostic tools for diseases in a field where few treatments, if any, are available. The company is currently incubated at l’Institut du Cerveau et de la Moelle épinière in Paris (ICM).
