Thymosin α1 is an immunomodulator peptide formed from the cleavage of prothymosin α.1 Thymosin α1 inhibits the growth of 5TGM1 mouse and OPM-2, LP-1, and U266 human multiple myeloma cells in vitro but not in vivo.2 It also increases CD3- and CD28-induced T cell proliferation in C57BL/KaLwRij splenocytes but not in allogeneic mixed lymphocyte reactions using C57BL/KaLwRij and BALB/c splenocyte co-cultures when used at a concentration of 20 μM. Thymosin α1 also inhibits the growth and migration of H1299, NL9980, and L9981 non-small cell lung cancer (NSCLC) cells that express high levels of programmed cell death ligand 1 (PD-L1) but not of A549 and SPC-A-1 NSCLC cells that express low PD-L1 levels.3 It also decreases the number of metastatic lesions in a L9981, but not an A549, NSCLC mouse xenograft model when administered at a dose of 20 mg/kg per day. Thymosin α1 (200 μg/kg) increases indoleamine 2,3-dioxygenase 1 (IDO1) expression and IL-10 levels and decreases IL-1β and TNF-α production in the lung in a p.Phe508del mutant cystic fibrosis transmembrane conductance regulator (CFTRF508del/F508del) mouse model of cystic fibrosis and chronic A. fumigatus infection.4

Thymalfasin (thymosin-alpha 1) therapy in patients with chronic hepatitis B
J Gastroenterol Hepatol 2004 Dec;19(12):S73-5.15641208
Chronic hepatitis B virus (HBV) infection is a serious clinical problem because of its world-wide distribution and potential adverse sequelae. Globally, there are approximately 350 million people infected with chronic HBV, 75% of whom live in the Asia-Pacific region. Interferon-alfa and direct anti-viral agents such as lamivudine and adefovir are effective in the therapy of chronic HBV infection but the efficacy is far from satisfactory, particularly in perinatally infected patients, patients with lower ALT levels and those with HBeAg-negative chronic hepatitis B. Thymalfasin (thymosin-alphal) is an immunoregulatory agent able to enhance Thl response. It has been shown to trigger maturational events in lymphocytes, to augment T-cell function, and to promote reconstitution of immune defects. Studies are underway in both monotherapy and combination therapy with Thymalfasin and interferon and results are promising.

Thymalfasin: an immune system enhancer for the treatment of liver disease
J Gastroenterol Hepatol 2004 Dec;19(12):S69-72.15641207
Thymalfasin (thymosin-alpha 1) is an immunomodulating agent able to enhance the Thl immune response. It has been evaluated for its immunomodulatory activities and related therapeutic potential in several diseases, including chronic hepatitis B and C, AIDS, primary immunodeficiency diseases, depressed response to vaccination and cancer. The basis for effectiveness in these conditions is primarily through modulation of immunological responsiveness, as Thymalfasin has been shown to have beneficial effects on numerous immune system parameters and to increase T-cell differentiation and maturation. Thymalfasin is responsible for reconstitution of immune function when thymic tissue is given back to thymectomized animals. In addition, Thymalfasin has been shown to have efficacy in multiple experimental models of immune dysfunction, mainly, infectious diseases such as hepatitis (woodchuck) and influenza (mouse), and cancer such as melanoma (mouse) and colorectal carcinoma (rat) where Thymalfasin has shown antitumor effects.

Thymalfasin for the treatment of chronic hepatitis C infection
Expert Rev Anti Infect Ther 2005 Dec;3(6):885-92.16307501 10.1586/14787210.3.6.885
Approximately 50% of treatment-naive hepatitis C patients fail to achieve a sustained virologic response with standard peginterferon and ribavirin therapy. Patients who are infected with genotype 1 have high viral loads and are nonresponders to previous therapy, and are even more difficult to treat, underscoring the need for new therapeutic options. Thymalfasin (thymosin-alpha1), in combination with peginterferon-alpha2a, has demonstrated efficacy among difficult-to-treat patients with hepatitis C. The addition of ribavirin to Thymalfasin and peginterferon-alpha2a has also exhibited promising results among patients who have genotype 1 hepatitis C, high viral loads and are nonresponders to previous therapy.
