Introduction: Although convalescent plasma (CP) treatment is a potential therapeutic option for patients with COVID-19, there is a paucity of data from intensive care unit (ICU) patients with COVID-19 in low-resource settings, such as Suriname. CP was produced by a novel gravity-based filtration method. Methods: In an open-label, multi-center, non-randomized prospective clinical trial, patients with severe or life- threatening COVID-19 symptoms (n=28) with CP treatment were compared with standard treatment alone (n=50). A pre-planned interim analysis is reported. The primary endpoint was a 28-day ICU mortality. Secondary endpoints were changes two days after treatment initiation in pulmonary oxygen exchange capacity (PF ratio) and chest x-ray (CXR) score. Results: Mortality occurred in 18% (CP: 5/28) vs. 36% (Control:18/50). CP treatment of severe COVID-19 resulted in a higher probability of survival, with a hazard ratio (HR) of 0.22 (95% CI, 0.074-0.067), correcting for age, the presence of diabetes and COVID-19 severity. In the severe group, CP resulted in an improved CXR score (P = 0.0013) and increase in PF ratio (P = 0.011) as compared to standard therapy. The gravity-based plasmapheresis method used for CP production was well-tolerated and no adverse events were observed in the donors. Discussion: CP therapy in combination with standard treatment resulted in 78% reduction of 28-day ICU mortality (HR = 0.22) compared to standard treatment alone. Both CXR-score and PF ratio changes represent effective indicators for the treatment effect of CP after two days. The novel CP production method was effective and represents a practical solution for Low- and middle-income countries to produce CP.
