Description: Ledipasvir, also known as GS-5885; is an inhibitor of the hepatitis C virus NS5A protein and is a drug for the treatment of hepatitis C that was developed by Gilead Sciences. On October 10, 2014 the FDA approved the combination product ledipasvir 90 mg/sofosbuvir 400 mg (trade name Harvoni). The ledipasvir/sofosbuvir combination is a direct-acting antiviral agent that interferes with HCV replication and can be used to treat patients with genotypes 1a or 1b without PEG-interferon or ribavirin.

More Info:

Biological target: Ledipasvir (GS-5885) is an inhibitor of the hepatitis C virus NS5A, with EC50s of 34 pM and 4 pM against genotype 1a and 1b replicon, respectively. Ledipasvir is also a SARS-CoV 3CLpro inhibitor with an IC50 of 1.62 μM.
In vitro activity: LDV has picomolar and selective antiviral activity in multiple HCV genotype 1a and 1b replicon cell lines, with EC50 values of 0.031 nM and 0.004 nM, respectively (Table 1), and has low cellular toxicity (CC50, ≥10,000 nM [Table 3]). LDV is also active against genotypes 4a, 4d, 5a, and 6a, with EC50 values of 0.39 nM, 0.29 nM, 0.15 nM, and 0.11 to1.1 nM, respectively. In summary, LDV active antiviral activity against multiple HCV genotypes and its orthogonal resistance profile and additive to synergistic antiviral activity when combined with other classes of HCV inhibitors support its use in combination with SOF and other DAA agents for the treatment of chronic HCV infection.
