  • HCV Treatment PIPELINE REPORT 2019
    Pipeline Report » 2019 HCV Treatment PIPELINE REPORT 2019 Waiting for Generics By Annette Gaudino Since the adoption of theWorld Health Organization (WHO) health sector strategy to eliminate viral hepatitis as a public health threat, civil society has demanded care for all those living with chronic hepatitis C virus (HCV) infection. Sofosbuvir was approved in the United States as the first interferon-free curative treatment for HCV in December 2013. Yet in the years since, only 5.5 million of the 71 million people worldwide living with chronic HCV have been treated. And while Egypt and a handful of high-income countries make slow progress toward the WHO interim 2020 goals, global 2030 targets continue to recede over the horizon, with significant progress requiring more cures each year than new infections. This is an almost insurmountable challenge when drug use remains criminalized, and extrajudicial violence and social exclusion are the norm for people who inject and use criminalized substances. Despite overwhelming evidence of the efficacy of pangenotypic direct-acting antivirals (DAAs) across patient subgroups and among people actively injecting and using criminalized substances, barriers to universal treatment access remain stubbornly in place. Too often, national health ministries require in-country clinical trials to prove efficacy, and payers and providers require sobriety in order prescribe. Originator companies continue to ignore middle-income country markets or delay registration for generic manufacture under voluntary licenses. Multinational trade agreements, in particular as pursued by the United States Trade Representative, seek to strengthen patent monopolies and threaten the sovereignty of governments that put their people over corporate profits.
