What: Shares of biotechnology company Gilead Sciences (Nasdaq: GILD ) plunged 15% Friday after it reported disappointing trial results for its experimental hepatitis C drug.
So what: Gilead said that most of the hepatitis C genotype 1 patients it treated with its GS-7977 drug relapsed after a course of treatment, triggering fresh concerns over the drug's efficacy in some patients. Naturally, the news bodes well for rival hep C treatment developers Vertex Pharmaceuticals (Nasdaq: VRTX ) and Achillion Pharmaceuticals (Nasdaq: ACHN ) , whose shares are both up big today.
Now what: I'd look into this pullback as a possible buying opportunity. While Gilead was certainly dealt a setback, all companies in the hep C drug race will likely face the same challenge of treating the hepatitis C genotype 1 population with just one drug. Given the fact that it already has several drugs in its pipeline it can possibly combine with GS-7977, Gilead still seems like the smart bet to be the first to market.
