Over a year af­ter re­jec­tion, Im­munomedics emerges with po­ten­tial block­buster ap­proval

A tur­bu­lent 16 months for Im­munomedics has end­ed in a po­ten­tial block­buster ap­proval, as the FDA grant­ed an ac­cel­er­at­ed OK for their drug to treat an ag­gres­sive form of breast can­cer.

The drug, brand­ed as Trodelvy, is ap­proved for metasta­t­ic triple neg­a­tive breast can­cer — breast can­cers that lack the onco­genes that tar­get­ed ther­a­pies go af­ter and that have helped make the dis­ease treat­able for some pa­tients. The drug, which had break­through sta­tus and pri­or­i­ty re­view, showed a 33% re­sponse and me­di­an du­ra­tion of re­sponse of 7.7 months in 108 pa­tients en­rolled in their Phase II tri­al. Peak sales es­ti­mates can range as high as around $3 bil­lion.
