FDA proposes ending six-month primate tests for some antibodies, favoring human-relevant alternatives.
The FDA has proposed reducing or eliminating six-month primate toxicity tests for certain monoclonal antibody drugs, favoring human-relevant alternatives like computer models and lab-grown tissues.
The draft guidance aims to speed drug development, cut costs, and improve accuracy by replacing outdated animal testing, which often fails to predict human responses.
While animal advocates welcome the shift, critics caution against abrupt changes that could risk public health progress.
The move aligns with broader efforts to modernize safety testing and reduce reliance on non-human primates, though final rules are pending public comment.
