Merimepodib(VX-497) is a drug which acts as an inhibitor of theenzymeinosine monophosphate dehydrogenase,which is required for the synthesis ofnucleotidebases containingguanine.This consequently inhibits synthesis of DNA and RNA, and results inantiviralandimmunosuppressiveeffects.[1]It progressed as far as Phase 2b humanclinical trialsagainstHepatitis Cbut showed only modest benefits in comparison to existing treatments,[2][3]however it continues to be researched, and also shows activity against other viral diseases such asZika virusandfoot and mouth disease virus.[4][5]

Merimepodib was investigated in combination with remdesivir in a phase 2 clinical trial in the U.S. as a potential treatment ofCOVID-19by ViralClear Pharmaceuticals.[6][7]The trial stopped in October 2020, and the company announced in a news release that it was "unlikely that the trial would meet its primary safety endpoints", and that it "does not intend to further develop merimepodib".[8]
