Studies this site relies on

Ordered by strength of design. Conclusions are quoted verbatim from each abstract as indexed by PubMed; read the full paper before relying on any of them.

  1. Meta-analysis Antiviral Res · 2008 PMID 18078676

    Comparison of the efficacy of thymosin alpha-1 and interferon alpha in the treatment of chronic hepatitis B: a meta-analysis

    Yang YF, Zhao W, Zhong YD, et al.

    These data showed that compared with IFNalpha, the benefit of Talpha1 was not immediately significant at the end of therapy, but virological, biochemical and complete response had a tendency to increase or accumulate gradually after the therapy. For three of the four trials that studied HBeAg-negative patients, the results are mostly …

  2. Phase 3 trial BMJ · 2025 PMID 39814420

    The efficacy and safety of thymosin α1 for sepsis (TESTS): multicentre, double blinded, randomised, placebo controlled, phase 3 trial

    Wu J, Pei F, Zhou L, et al.

    This trial found no clear evidence to suggest that thymosin α1 decreases 28 day all cause mortality in adults with sepsis.

  3. Randomized trial Crit Care · 2013 PMID 23327199

    The efficacy of thymosin alpha 1 for severe sepsis (ETASS): a multicenter, single-blind, randomized and controlled trial

    Wu J, Zhou L, Liu J, et al.

    The use of Tα1 therapy in combination with conventional medical therapies may be effective in improving clinical outcomes in a targeted population of severe sepsis.

  4. Randomized trial J Viral Hepat · 2005 PMID 15850471

    The efficacy and safety of thymosin alpha-1 in Japanese patients with chronic hepatitis B; results from a randomized clinical trial

    Iino S, Toyota J, Kumada H, et al.

    Adverse event incidence was similar in the 1.6- and 0.8-mg treatment groups. In conclusion, Talpha1 at doses of 0.8 and 1.6 mg exhibits long-term efficacy against hepatitis B with a good safety profile.

  5. Primary study J Infect Dis · 2023 PMID 36056913

    A Pilot Trial of Thymalfasin (Thymosin-α-1) to Treat Hospitalized Patients With Hypoxemia and Lymphocytopenia Due to Coronavirus Disease 2019 Infection

    Shehadeh F, Benitez G, Mylona EK, et al.

    Tα1 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.

  6. Review World J Virol · 2020 PMID 33362999

    Thymosin alpha 1: A comprehensive review of the literature

    Dominari A, Hathaway Iii D, Pandav K, et al.

    In this review, we discuss key literature on the background knowledge and current clinical uses of thymosin alpha 1. Considering the known biochemical properties including antibacterial and antiviral properties, time-honored applications, and the new promising findings regarding the use of thymosin, we believe that thymosin alpha 1 …
