The Claim
The failure rate for translation of drugs from animal testing to human clinical treatments remains at over 92%, a rate that has persisted consistently over the past few decades.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Most drugs that look promising in animal studies—over 92% of them—end up failing when researchers try to use them in humans, and this high failure rate hasn't changed much in decades.
See the scientific wording
The failure rate for translation of drugs from animal testing to human treatments remains at over 92%, where it has been for the past few decades
What the research says
1 studyStudy: Poor Translatability of Biomedical Research Using Animals — A Narrative Review
The study directly confirms that over 92% of drugs that work in animal tests fail when tried on humans, and this has been the case for decades - exactly matching the claim.
