Double-blind RCT 730 patients in the USA (March 2021 - April 2022) Improved viral clearance with proxalutamide (p=0.0001) c19early.org Kintor, Press Release, April 2022 0 0.5 1 1.5 2+ RR
RCT 733 outpatients, 99% in the USA, showing lower hospitalization/death, and significantly reduced viral load with proxalutamide treatment. The viral clearance result is from Ma et al.
Standard of Care (SOC) for COVID-19 in the study country, the USA, is very poor with very low average efficacy for approved treatments2. 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.
