Disease program
chronic hepatitis C virus infection

RNA-directed RNA polymerase shows approved-linked disease relevance led by chronic hepatitis C virus infection. 5 more disease programs remain visible in the same review block. 18 linked drugs remain visible in the same block.

Start review with chronic hepatitis C virus infection because it currently carries approved-linked support. Linked drugs include ABT-072, ADAFOSBUVIR, BALAPIRAVIR, BECLABUVIR. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
