No result from this study comes from a test of the peptide.

Studies that did not test the peptide alone5

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.

    We studied the effect of combined chemo-immunotherapy, 5-FU followed by thymosin alpha 1 (T alpha 1) and interleukin-2 (IL-2) at low doses, on liver metastases from colorectal cancer, induced by splenic injection of DHD/K12 cells (1,2-dimethylhydrazine-induced colon adenocarcinoma) in syngeneic BDIX rats.

    Evaluable rats were assigned randomly to 5 experimental groups designated as control, 5-FU, IL-2, 5-FU/IL-2 and 5-FU/T alpha 1/IL-2.
