Neither remdesivir nor REGN-COV2 have completed large-scale randomised trials, say UK scientists
Scientists still lack conclusive proof that the two anti-Covid drugs given to Donald Trump are clinically effective.
UK researchers point out that both medicines – remdesivir and REGN-COV2 – have still to complete the large-scale, randomised trials needed to demonstrate fully their ability to counter Covid-19 in patients. And many have criticised US authorities for their failures to carry out such trials. This has undermined efforts to find effective medicines to treat people affected by the disease.
