Adaptive Covid-19 Treatment Trial 1

ACTT-1 trial design and results
Design Double-blind, randomised, placebo-controlled trial
Treatment Intravenous remdesivir
Control Placebo
Population 1062 adults hospitalised with COVID-19 and evidence of lower respiratory tract infection
Follow-up 29 days
Primary endpoint Time to recovery
Result Median time to recovery 10 days (95% CI 9 to 11) with remdesivir versus 15 days (13 to 18) with placebo — rate ratio for recovery 1.29 (95% CI 1.12 to 1.49, p<0.001). The mortality difference did not reach statistical significance.
Secondary endpoints Mortality at day 15 and 29, clinical status on an ordinal scale, adverse events

Our data show that remdesivir was superior to placebo in shortening the time to recovery in adults who were hospitalized with Covid-19 and had evidence of lower respiratory tract infection.

How it has aged

A positive trial on a soft endpoint that has never been matched by a convincing mortality signal, and the WHO SOLIDARITY trial subsequently found no benefit. Compare RECOVERY dexamethasone, where a cheap steroid moved mortality in the same disease.
