In the roller coaster of life that is oncology R&D, molecules come and molecules go… a rare few reach blockbuster heights while many others are quietly packed off to dog drug heaven, never to be seen or heard of again.
This is also very true of targets as well…
What about the in-between space?
Unfortunately, that’s where most molecules and cancer targets end up – into a deep black nothingness where we seek the high affinity targets with low grade side effects – and fall short in some way. It’s a frustrating place to be, to be sure.
One of these conundrums is compounds against CD123 (IL3Rα), which have been in the spotlight on and off this year and are turning out to be a rather mixed bag.
After our recent update on Cellectis and their CD123 direct CAR T cell therapy (UCART123), I wasn’t expecting to write any more on this until ASH in mid December. How wrong that prediction turned out to be!
Today we have quite a few things to discuss on this topic, so if interested in CD123 in hematologic malignancies and going beyond that to find better targets in AML then this is the poster for you…
