PAXLOVID was evaluated in the pivotal EPIC-HR trial1EPIC-HR was a phase 2/3, randomised, double-blind, placebo-controlled study in nonhospitalised, unvaccinated symptomatic adults with SARS-CoV-2 with ≥1 risk factor for progression to severe disease (N=2113).1,2Study Design1,3Patient inclusion criteria:
  • Unvaccinated
  • Adults ≥18 years of age
  • Confirmed SARS-CoV-2 positive
  • COVID-19 symptom onset of ≤5 days
  • No previous SARS-CoV-2 infection
  • ≥1 of the following characteristics/comorbidities associated with increased risk of developing severe COVID-19 illness:
    • ≥60 years of age
    • BMI >25 kg/m2
    • Cigarette smoking
    • Immunosuppresive disease (including HIV infections with CD4+ T cell count <200 mm3 in viral load <400 copies/mL)

    • Hypertension
    • Chronic lung, cardiovascular, kidney, or sickle cell disease
    • Diabetes
    • Cancer
    • Neurodevelopmental disorders or other medically complex conditions

Study endpoints4Proportion of participants with a resting peripheral oxygen saturation ≥95% at Days 1 and 5.AE=adverse event; ICU=intensive care unit; PK=pharmacokinetics; RT-PCR=reverse-transcription polymerase chain reaction; SAE=serious adverse event; TEAE=treatment-emergent adverse event.
  • The key secondary analysis that informed the authorisation of PAXLOVID in Ireland was the percentage of relative risk reduction in hospitalisation or death in participants who were treated within 5 days of symptom onset
  • No patients had completed long-term follow-up at the time of this analysis (ie, through Week 24)
