The Efficacy of Different Anti-viral Drugs in COVID 19 Infected Patients


The (World Health Organization) WHO NOR- (Coronavirus infectious disease) COVID 19 study is a multi-centre, adaptive, randomized, open clinical trial to evaluate the safety and efficacy of hydroxychloroquine, remdesivir and standard of care in hospitalized adult patients diagnosed with COVID-19. This trial will follow the core WHO protocol but has additional efficacy, safety and explorative endpoints.

Full Title of Study: “The (Norwegian) NOR Solidarity Multicenter Trial on the Efficacy of Different Anti-viral Drugs in SARS-CoV-2 Infected Patients”

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Treatment
    • Masking: None (Open Label)
  • Study Primary Completion Date: August 2020


  • Drug: Hydroxychloroquine
    • Hydroxychloroquine will be given orally (in the ICU in gastrointestinal tubes) with 800 mg x 2 loading dose followed by 400 mg x 2 every day for a total of 10 days.
  • Drug: Remdesivir
    • Remdesivir will be given intravenously 100 mg daily for the duration of the hospitalization and up to 10 days total course. A loading dose of 200 mg at inclusion will be given.
  • Other: (Standard of Care) SoC
    • The standard of care will be supplied to all patients not receiving a drug intervention.
