I do not work for vertex or merck, but it is amazing how you speak with such conviction, yet you have no idea of what you are talking about. HIV is not the same as HCV, yet you state that these reps will simply rollover to HCV drugs. What relationships do they have in HCV, what knowledge or credibility do they have in HCV? It is logical to believe that HIV reps will continue to call on "HIV" doctors! There is very little crossover between HCV and HIV. If you want a precedent, just look at Roche, they had an HIV sales force, but also had a seperate HCV sales force. The fact of the matter is that Reps with HCV relationships and experience will be sought after, and that includes Vertex.
In addition, do you assume that Vertex will not conduct studies with some of these other oral agents, perhaps to also be part of an all oral regimen; of course they will. The treatments paradigmns in HCV will evolve, and will include a mix of cocktails, etc just like HIV. Vertex will not disappear just because of new competitors in the market. Just look at antibioticsm,, etc where there are/were many, many branded competitiors. Finally, there has not been a single "all oral' regimen that has yet proven to be as efficacious as the current standard of care (plus vertex or merck drug), in genotype one patients, not ONE!, including Pharmasset.
Vertex reps, dont panic, yes obviously as there are new competitors, new options things will become more complicated, and your job will actually become a little more interesting. However, that does not mean that your drug will not continue to be a viable treatment option. Just ignore the chicken littles of the world, that predict that the sky is falling.
