TMPRSS2 inhibitors

22nd treatment shown to reduce risk in April 2021, now with p = 0.0007 from 29 studies.

Lower risk for mortality, ventilation, and recovery.

No treatment is 100% effective. Protocols combine treatments.

5,900+ studies for 172 treatments. c19early.org

Early terminated RCT with 34 patients showing no significant differences with camostat treatment.

Standard of Care (SOC) for COVID-19 in the study country, the United Kingdom, is very poor with very low average efficacy for approved treatments1. The United Kingdom focused on expensive high-profit treatments, approving only one low-cost early treatment, which required a prescription and had limited adoption. The high-cost prescription treatment strategy reduces the probability of early treatment due to access and cost barriers, and eliminates complementary and synergistic benefits seen with many low-cost treatments.
