Harnessing the Power of RNAi Gene Silencing in a Quest of a Cure for Chronic Hepatitis B, and the HBV KnockDown blog written by Dirk Haussecker, who believes it’s about time everyone got serious about a functional cure for hepatitis B.
As I was reading the latest PK-PD study by Gilead on its lead experimental chronic HepB drug candidate GS-9620 (Fosdick et al. 2013), it finally dawned on me that much-touted GS-9620 has been designed to be nothing more than a better tolerated, more convenient version of an already existing treatment option, recombinant interferon. GS-9620 is therefore an example of the typical incrementalist Big Pharma value creation strategy. By contrast, if successful, an HBsAg knockdown approach such as with Arrowhead’s ARC520 would bring to healthcare providers and patients an entirely new, desperately needed treatment option as the field has become stuck with interferons and RT inhibitors for years.
