It's a waste of time. There isn't a model that can sufficiently simulate the chaotic behavior of biological cellular systems and the complex interactions with potential chemical treatments. Models are Mickey mouse representations of reality.
[1]: I own 4 (once 5) pet rats. They are only a small colony and, while I love them, I don't keep them at lab standards (for example, I don't a vet sleeping on the couch 24/7 in case of emergencies), yet, in a bad month, I could end up with spending 1000+$ for their health. Now, imagine that for the health standard of lab rats/mice and the numbers required for research.
