I agree that in the one copmpany CTIX there is a certain amount of built-in diversification already,.. 18 drugs in the pipe-line,.. the top 3 all blockbuster potential.
As well the more you look into each drug the more confidence one gets.
B = already passed Phase 2a
P = starting Phase 2/3
K- up to 110mg,... 6 re-staging, p21 increases at 20-30mg,..etc
Lots there to reduce the risk.
