No­var­tis punts a late-stage PI3K drug with a wor­ry­ing safe­ty pro­file to one of Chi­na’s up­start biotechs

Just months af­ter a group of re­searchers warned against the fur­ther de­vel­op­ment of a wor­ry­ing PI3K in­hibitor project No­var­tis had been work­ing on, the phar­ma gi­ant li­censed out the glob­al rights to a new­ly ac­tive Chi­nese biotech. 

No­var­tis is the lat­est in a long string of Big Phar­ma play­ers who have de­cid­ed to bow out of a trou­ble­some PI3K de­vel­op­ment pro­gram. But in­stead of drop­ping the drug the Swiss com­pa­ny hand­ed world­wide com­mer­cial rights to the late-stage bu­parlis­ib to one of Chi­na’s new up­start biotechs — rais­ing some thorny is­sues about how ques­tion­able drug as­sets may be passed to new play­ers for a com­mer­cial roll­out.
