An­oth­er old drug looks for a sec­ond com­ing at the FDA, this time for Duchenne MD

So far, drugs that try to ad­dress the root cause of Duchenne mus­cu­lar dy­s­tro­phy have had to trav­el a rocky road at the FDA. But reg­u­la­tors are now hus­tling up a re­view of a new treat­ment — new to the US at least— that will try to do what a line­up of well fi­nanced biotechs and phar­ma com­pa­nies have failed at.

Marathon Phar­ma­ceu­ti­cals put their DMD can­di­date de­flaza­cort through a Phase III study, and it says the drug pro­vid­ed ev­i­dence of im­prov­ing the mus­cle strength of boys, let­ting them do bet­ter at a va­ri­ety of phys­i­cal tasks, like sit­ting up or walk­ing. On Wednes­day, the FDA pro­vid­ed pri­or­i­ty re­view sta­tus for the drug when it ac­cept­ed the ap­pli­ca­tion for re­view, set­ting up an ac­cel­er­at­ed Feb­ru­ary PDU­FA dead­line on whether it should be used to treat DMD boys with the lethal dis­ease.
