FDA OKs Tesaro’s ni­ra­parib for ovar­i­an can­cer, hand­ing the biotech a big win on the la­bel

The FDA has wast­ed no time in giv­ing Tesaro $TSRO a broad ap­proval for the use of its PARP drug ni­ra­parib, which will now be mar­ket­ed as Ze­ju­la as a main­te­nance ther­a­py for re­cur­rent ovar­i­an can­cer.

The OK and the la­bel that came with it rep­re­sents a set­back for Myr­i­ad Ge­net­ics $MYGN, which had ar­gued that its com­pan­ion di­ag­nos­tic would be need­ed to iden­ti­fy a spe­cif­ic group of ovar­i­an can­cer pa­tients with a bio­mark­er in­di­cat­ing that they would most like­ly ben­e­fit. But reg­u­la­tors blew past any di­ag­nos­tic qual­i­fi­ca­tion in giv­ing Tesaro the la­bel that it was look­ing for, vin­di­cat­ing CEO Lon­nie Moul­der’s vow that he could get an OK aimed at a large seg­ment of the mar­ket.
