What is this study about?

REMAP-CAP is an international (15 countries) adaptive platform trial in community acquired pneumonia, that was specifically designed to be employed in a pandemic to evaluate multiple interventions simultaneously in critically ill patients. In addition to recruiting patients with community acquired pneumonia who have been admitted to critical care, we are also recruiting patients with COVID-19 to understand optimal treatment strategies.

The trial is modular so that new domains (groups of similar treatment options) can be added over time.

COVID-19 treatment domains:

  • Antivirals 
    Four interventions: (1) no antiviral; (2) lopinavir/ritonavir; (3) hydroxychloroquine; (4) lopinavir/ritonavir and hydroxychloroquine combination – Interventions including hydroxychloroquine are no longer open for recruitment
  • immunomodulation
    Five interventions: (1) no immune modulation; (2) interferon beta 1a; (3) interleukin 1 receptor antagonist [anakinra]; (4 and 5) interleukin 6 inhibition [tocilizumab and sarilumab]
  • Immunoglobulin therapy
    Two interventions: (1) no immunoglobulin; (2) convalescent plasma
  • Therapeutic anticoagulation
    Two interventions: (1) local standard venous thromboprophylaxis; (2) therapeutic anticoagulation with intravenous unfractionated heparin or subcutaneous low molecular weight hepari
  • Antiplatelet
    Three interventions: (1) No antiplatelet; (2) Asprin; (3) P2Y12 inhibitor (clopidogrel, prasugrel or ticagrelor) 
  • Vitamin C
    Two interventions: (1) no vitamin C; (2) vitamin C
  • Statin therapy
    Two interventions: (1) no statin therapy; (2) simvastatin
  • Corticosteroids (three interventions: (1) no steroids; (2) steroids for 7 days (3) steroids if shock present) – no longer open for recruitment

Community Acquired Pneumonia treatment domains:

  • Antibiotics
    Five interventions: (1) Ceftriaxone + Macrolide; (2) Moxifloxacin or Levofloxacin; (3) Piperacillin-tazobactam + Macrolide (4) Ceftaroline + Macrolide (5) Amoxicillin-clavulanate + Macrolide
  • Macrolide duration
    Two interventions: (1) standard course (3-5 days); (2) extended course (14 days)
  • Corticosteroids
    Three interventions: (1) no steroids; (2) steroids for 7 days (3) steroids if shock present
  • Antivirals (influenza)
    Three interventions: (1) no antiviral for influenza; (2) Oseltamivir (5 days); (3) Oseltamivir (10 days)
  • Vitamin C
    Two interventions: (1) no vitamin C; (2) vitamin C
