“…The RECOVERY (Randomized Evaluation of COVID-19 therapy), REMAP-CAP (Randomised, Embedded, Multi-factorial, Adaptive Platform Trial for Community-Acquired Pneumonia), and WHO-SOLIDARITY clinical trials were based on extensive multicenter collaboration, adaptive design in randomized controlled trials (RCTs) and the utilization of preprints. They provided an influx of good-quality evidence and led to profound clinical practice changes over time for patients who were not pregnant [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 ]. However, it was particularly challenging to derive evidence regarding treatment guidelines for populations with additional treatment safety concerns, such as the pediatric and pregnant patients.…”
