Festinavir is an investigational new drug being developed by Bristol Myers-Squibb for the treatment of HIV infection. Festinavir is a nucleoside reverse transcriptase inhibitor that is active against HIV resistant to both abacavir and tenofovir making the drug a candidate for people with multi-drug resistant (MDR) strains of the virus. Festinavir is a derivative of stavudine (d4T) but is less toxic.[citation needed] It was originally developed at Yale University.
