Randomized Controlled Trial Multicenter Study Clinical Trial
A randomized controlled trial of thymosin-alpha1 versus interferon alfa treatment in patients with hepatitis B e antigen antibody--and hepatitis B virus DNA--positive chronic hepatitis B.
It has recently been shown that thymosin-alpha1(T-alpha1), a synthetic polypeptide of thymic origin, is able to promote disease remission and inhibition of hepatitis B virus (HBV) replication in patients affected by hepatitis B e antigen (HBeAg)-positive chronic active hepatitis. We evaluated the efficacy and safety of T-alpha1 treatment in patients with hepatitis B e antibody (anti-HBe) and HBV-DNA-positive chronic hepatitis. Thirty-three patients were randomly assigned to receive either T-alpha1 900 microg/m2 body surface area twice weekly (17 patients) or 5 MU of interferon alfa (IFN-alpha) three times weekly (16 patients) for 6 months. ⋯ Furthermore, compared with IFN-alpha, T-alpha1 is better tolerated and seems to induce a gradual and more sustained ALT normalization and HBV-DNA loss. In conclusion, T-alpha1 appears to be a safe and effective alternative treatment for anti-HBe-positive chronic hepatitis. The benefit of this agent in producing long-term inhibition of HBV replication must be confirmed by future trials.
