Researchers expect three waves of small-molecule drug approvals, each of which will improve HCV treatment. First, telaprevir and boceprevir are likely to be approved next year as add-ons to the current treatment regimen. The second wave, in three to five years, will bring second-generation protease blockers, a crop of polymerase inhibitors, and new classes of compounds such as Bristol-Myers Squibb’s NS5A inhibitor and Debiopharm’s cyclophilin inhibitor. Finally, researchers hope that in the next five to 10 years they will reach the ultimate goal—enough data to convince doctors and the Food & Drug Administration that the virus can be quieted with combinations of small molecules alone.
