Re: 520 for MM as MCL-1 inhibitor. Interesting (since I used to follow CYTK's effort with KSP), so how does it stack up against ABT's navitoclax, which is at about the same stage of testing in MM, and uses the same MOA? Don't have enough time & skin in the game, myself, but you may want to check out that program.
