Did you know 3.4% of oncology drugs in clinical trials get FDA approval?  

The burden of evidence required to take a drug to market is very high and clinical trials are costly with a low chance of success.  This is one of the reasons that newly approved drugs cost so much to patients.  

Is there a better way?

The FDA legitimately requires drug developers to do mouse studies before in-human studies.

I would be surprised if there was a significant translation of clinical efficacy from rats to humans.

It will be difficult to achieve that clinical efficacy, because most oncology drugs end up harming the rats before going into testers

But this is sad, only 3.4%😭😭😭
