Talviraline (HBY 097) was developed as a nonnucleoside inhibitor of human immunodeficiency virus type 1 (HIV-1) reverse transcriptase (NNRTI) for the treatment of HIV Infections. Talviraline participated in a phase II clinical trial. It was found that the drug caused pronounced acute suppression of HIV-1 replication both in combination with zidovudine and alone. However, further development of the drug has been discontinued.
