What: Shares of hepatitis-focused biotech company Achillion Pharmaceuticals
So what: This was not a pleasant past couple of days for Achillion shareholders, who've been hit with a triple-whammy. First, last week, Gilead Sciences
Now what: There's no question that the bounty placed on the hepatitis-C sector is huge, but investors have been reaching out for any positive news for months, whether it really existed or not. It's becoming clear that Gilead's experimental drug has the fast track to success and other hepatitis-C-drug hopefuls are going to be fighting an uphill battle. ACH-1625 still has a long way to go and I just don't see how it's going to unseat GS-7977, especially since GS-7977 will probably beat ACH-1625 to market, assuming that both are approved. Despite today's drop, I'll gladly pass on Achillion.
