Lyell far ahead of JNJ and Kite CD19/20, many more patients, treating an apparently much sicker group, showing longer durability, looks like favorable tox. The days of CD19 alone are over. CD19/20 wins, and JNJ, KITE are behind. (ARCH was the first venture backer of Carl June

Pitchbook data on biotech fund raises by year via BioSpace. No wonder we've felt the pain of coming off 2018-2019 but it's looking quite anaemic now.
