Gilead Sciences Inc. (GILD) announced that it has expanded its hepatitis C generic licensing agreements to include the investigational NS5A inhibitor GS-5816, which is being evaluated in Phase 3 clinical studies as part of a single tablet regimen that combines the compound and sofosbuvir for the treatment of all six genotypes of hepatitis C.
Gilead noted that the expanded agreements will allow its India-based partnersto manufacture GS-5816 and the single tablet regimen of sofosbuvir/GS-5816, once approved, for distribution in 91 developing countries, which together account for 54 percent of the total worldwide population of individuals infected with the hepatitis C virus or HCV.
If approved by regulatory authorities, the sofosbuvir/GS-5816 regimen would become the first pan-genotypic, all-oral single tablet regimen for HCV. A pan-genotypic therapeutic option is particularly important for developing countries, where genotype testing is often unreliable or not readily available.
The amended agreements expand on Gilead's existing generic licensing partnerships for hepatitis C, announced in September 2014, under which partners may produce sofosbuvir and the single tablet regimen of ledipasvir/sofosbuvir. Eight Indian-based generic manufacturers now hold licenses to manufacture Gilead's HCV medicines - Biocon Ltd., Cadila Healthcare Ltd., Cipla Ltd., Hetero Labs Ltd., Mylan Laboratories Ltd., Ranbaxy Laboratories Ltd., Sequent Scientific Ltd. and Strides Arcolab Ltd.
Sofosbuvir recently received regulatory approval in India (January 2015), and regulatory submissions have been completed in additional countries, including Pakistan, Thailand, Brazil, Uganda, South Africa and Nigeria.
The single tablet regimen of sofosbuvir/GS-5816 is an investigational agent and its safety and efficacy have not been established. Phase 3 studies evaluating the combination of GS-5816 and sofosbuvir are currently underway, with data anticipated in the second half of 2015.
