The Standard of Care Combined With Glucocorticoid in Elderly People With Mild or Moderate COVID-19

A Bidimensional Early Intervention Strategy of Standard of Care Combined With Host Immunomodulation in Elderly Patients With Mild or Moderate COVID-19: A Multicentre, Randomized, Controlled, Adaptive Platform Study

This study is aimed to explore the dual-dimensional early intervention strategy of standard of care combined with host immunomodulation in elderly patients with mild and moderate COVID-19.

In this multicentre, randomized, controlled, and adaptive platform trial exploring the efficacy and safety of short-term and low-dose glucocorticoid combined with standard of care in mild or moderate elderly patients (with or without other high-risk factors) who are over 65 years.We are looking for the best treatment strategy to prevent mild or moderate COVID-19 from developing into severe/critical COVID-19, so as to reduce the risk of disease progression and death in the elderly patients and benefit more patients.
