#ASH20: Out to shake up CML once again, No­var­tis lays out head-to-head be­tween third-gen Gleevec scion and Pfiz­er ri­val

No­var­tis says its third-gen­er­a­tion chron­ic myeloid leukemia drug — a scion to the fad­ing block­buster Gleevec — near­ly dou­bled the re­sponse rate among pa­tients who have pro­gressed af­ter two lines of treat­ment, paving the way to shake up the space once again.

The phar­ma gi­ant re­port­ed a 25.5% ma­jor mol­e­c­u­lar re­sponse rate for as­ci­minib at week 24, com­pared to 13.2% on Pfiz­er’s Bo­sulif (p=0.029). The as­ci­minib arm al­so had more pa­tients achiev­ing a com­plete cy­to­ge­net­ic re­sponse; 40.8% did, ver­sus 24.2% in the oth­er group. In to­tal, the tri­al en­rolled 233 pa­tients.
