Washington, DC - Tenofovir disoproxil fumarate (TDF), an antiviral drug commonly prescribed to treat hepatitis B infection, does not significantly reduce mother-to-child transmission of hepatitis B virus when taken during pregnancy and after delivery, according to a phase III clinical trial in Thailand funded by the National Institutes of Health.

The results appear in the New England Journal of Medicine.

Cambridge, Massachusetts - Pharmaceutical companies once considered a protein called p38 a very attractive target for treating rheumatoid arthritis.
