Preprints are preliminary research reports that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.
Preprints posted online allow authors to receive rapid feedback and the entire scientific community can appraise the work for themselves and respond appropriately. Those comments are posted alongside the preprints for anyone to read them and serve as a post publication assessment.

ABSTRACT
BackgroundCoronavirus disease 2019 (Covid-19) active cases continue to demand the development of safe and effective treatments. This is the first clinical trial to evaluate the safety and efficacy of oral thymic peptides. MethodsWe conducted a nonrandomized phase 2 trial with a historic control group to evaluate the safety and efficacy of a daily 250-mg oral dose of thymic peptides in the treatment of hospitalized Covid-19 patients. Comparison based on standard care from registry data was performed after propensity score matching. The primary outcomes were survival, time to recovery and the number of participants with treatment-related adverse events or side effects by day 20. ResultsA total of 44 patients were analyzed in this study, 22 in the thymic peptides group and 22 in the standard care group. There were no deaths in the intervention group, compared to 24% mortality in standard care by day 20 (log-rank P=0.02). The Kaplan-Meier analysis showed a significantly shorter time to recovery by day 20 in the thymic peptides group as compared with standard care (median, 6 days vs. 12 days; hazard ratio for recovery, 2.75 [95% confidence interval, 1.34 to 5.62]; log-rank P=0.002). No side effects or adverse events were reported. ConclusionIn patients hospitalized with Covid-19, the use of thymic peptides reported no side effects, adverse events, or deaths by day 20. When compared with registry data, a significantly shorter time to recovery and mortality reduction was measured. The Catholic University of Honduras Medical Research Group (GIMUNICAH) is working on a more extensive phase 3 trial. Trial registrationClinicalTrials.gov NCT04771013. February 25, 2021.
