- Abstract
ABSTRACTIntroductionHepatitis delta virus (HDV) causes acute and chronic liver disease that requires the co-infection of the Hepatitis B virus and can lead to significant morbidity and mortality. Bulevirtide is a recently introduced entry inhibitor drug that acts on the sodium taurocholate cotransporting peptide, thereby preventing viral entry to target cells in chronic HDV infection. The mainstay of chronic HDV therapy prior to bulevirtide was interferon alpha, which has an undesirable side effect profile.Areas CoveredWe review bulevirtide data from recent clinical trials in Europe and the United States. Challenges to development and implementation of bulevirtide are discussed. Additionally, we review ongoing trials of emerging drugs for HDV, such as pegylated interferon lambda and lonafarnib.Expert OpinionBulevirtide represents a major shift in treatment for chronic HDV, for which there is significant unmet need. Trials that compared bulevirtide in combination with interferon alpha vs interferon alpha monotherapy demonstrated significant increase in virologic response. Overall, treatment with different doses of bulevirtide were comparable. Bulevirtide was generally well tolerated, and no serious adverse events occurred. Understanding the true prevalence of HDV, as well as continued studies of emerging drugs will prove valuable to the larger goal of eradication of Hepatitis D.
