ABSTRACT
Background. Thymosin-alpha-1 (T alpha 1) may be a treatment option for coronavirus disease 2019 (COVID-19), but efficacy and safety data remain limited. Methods. Prospective, open-label, randomized trial assessing preliminary efficacy and safety of thymalfasin (synthetic form of T alpha 1), compared with the standard of care, among hospitalized patients with hypoxemia and lymphocytopenia due to COVID-19. Results. A total of 49 patients were included in this analysis. Compared with control patients, the incidence of clinical recovery was higher for treated patients with either baseline low-flow oxygen (subdistribution hazard ratio, 1.48 [95% confidence interval, .68-3.25] ) or baseline high-flow oxygen (1.28 [.35-4.63]), although neither difference was significant. Among patients with baseline low-flow oxygen, treated patients, compared with control patients, had an average difference of 3.84 times more CD4(+) T cells on day 5 than on day 1 (P = .01). Nine serious adverse events among treated patients were deemed not related to T alpha 1. Conclusions. T alpha 1 increases CD4(+) T-cell count among patients with baseline low-flow oxygen support faster than the standard of care and may have a role in the management of hospitalized patients with hypoxemia and lymphocytopenia due to COVID-19.
