That's not really where most biotechs die.

You don't move a drug into clinical trials unless you can replicate the initial studies, which is almost always "drug x cures y in animal z."

They die when they try to determine if "drug x cures y in humans."

Series A companies die there. That’s why most not largest.

"drug x cures y in humans - without causing z where bad_y - bad_z < ε".

> where bad_y - bad_z < ε".

LOL. That is often the hard part. "We cured your toe fungus. Sorry about the heart attack."
