Thank you for this! I'm starting my new job as an oncology CRC in early phase trials soon! Needing all the info I can get before my first day

After a phase 1/2a, would you move on to a phase 2b or are there cases where you would jump directly to a phase 3 trial and skip 2b? Does it depend on the indication and drug being tested?

[@dansfera]

depends on fda and the pathway

This is a mess and I have the feeling that there're not definitive agreed upon definitions... Thank you for trying anyway!
