Two flops in two weeks for Mar­i­nus Phar­ma­ceu­ti­cal­s' ganax­olone 

Days af­ter Mar­i­nus Phar­ma­ceu­ti­cal’s ganax­olone failed on an epilep­sy study, the same drug failed a Frag­ile X syn­drome tri­al, fur­ther bruis­ing the biotech’s al­ready bad­ly dam­aged mar­ket val­ue.

Rather in­cred­i­bly, the biotech ($MRNS) claims it didn’t ex­pect to hit the pri­ma­ry end­point: over­all im­prove­ment across the Frag­ile X syn­drome. In­stead the biotech hailed da­ta on ganax­olone’s ef­fec­tive­ness in treat­ing anx­i­ety for pa­tients and in­tends to use that to find some path for­ward for the GABAA mod­u­la­tor.
