SAFEty Study of Early Infusion of Vitamin C for Treatment of Novel Coronavirus Acute Lung Injury (SAFE EVICT CORONA-ALI)

Fowler et al., NCT04344184, SAFE EVICT CORONA-ALI, NCT04344184, Apr 2024

Vitamin C for COVID-19

6th treatment shown to reduce risk in September 2020, now with p = 0.000000069 from 72 studies, recognized in 22 countries.
Lower risk for mortality, ICU, hospitalization, and recovery.

No treatment is 100% effective.
Protocols combine treatments.

RCT 47 ICU patients showing no significant differences with vitamin C treatment.
Although the 19% lower mortality is not statistically significant, it is consistent with the significant 19% lower mortality [9‑27%] from meta-analysis of the 44 mortality results to date.
This is the 20th COVID-19 RCT for vitamin C, which collectively show efficacy with p=0.0016.
This is the 67th of 72 COVID-19 controlled studies for vitamin C, which collectively show efficacy with p=0.000000069.
Standard of Care (SOC) for COVID-19 in the study country, the USA, is very poor with very low average efficacy for approved treatments1. Only expensive, high-profit treatments were approved for early treatment. Low-cost treatments were excluded, reducing the probability of early treatment due to access and cost barriers, and eliminating complementary and synergistic benefits seen with many low-cost treatments. This may explain in part the very high mortality seen in this study. Results may differ in countries with improved SOC.
This study is excluded in the after exclusion results of meta-analysis: very late stage, ICU patients.
