In this study, Thymosin alpha-1 was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Thymosin alpha-1.

  1. 01AnimalNot a test of Thymosin alpha-1 aloneAnimal study (in vivo)Efficacy outcome

    In mice infected with influenza A PR8 virus, amantadine plus thymosin alpha‑1 followed by IFN gave significantly better long-term survival than single agents with chemotherapy or chemotherapy alone.

    In plain wordsIn infected mice, a combination of amantadine, thymosin alpha‑1 and interferon improved long-term survival compared with single agents plus amantadine or amantadine alone.

    Summary
    The effectiveness of this new chemoimmunotherapy protocol was seen in the long-term survival of a high percentage of animals and was statistically significant when compared to treatment with single agents in conjunction with chemotherapy or to chemotherapy alone.

    Summary · context
    The aim of this study was to examine the effects of the antiviral drug amantadine (AMN) administered in combination with thymosin alpha 1 (T alpha 1) and murine alpha/beta interferon (IFN) on mice infected with influenza A PR8 virus.
    Summary · context
    Combined treatment with AMN and T alpha 1, for 4 days, followed by a single injection of IFN, was initiated 1 h after intranasal viral inoculation.

    Summary
    In addition, chemoimmunotherapy treatment reduces the viral titre in the lungs as well as restoring the immunological parameters tested (natural killer cell activity; cytotoxic T-lymphocyte responses; CD4+/CD8+ lymphocyte subsets) with respect to all other groups.
