Merck Seals Hepatitis C Pact with Roche

Merck is going bare knuckles in the marketing battle for Hepatitis C patients. Just days after receiving FDA approval to market its protease inhibitor boceprevir, now known as Victrelis, it revealed Roche has signed on to co-promote the drug alongside its pegylated interferon drug Pegasys, a cornerstone of HCV treatment.

Competition in the HCV arena is expected to be fierce, as Vertex Pharmaceuticals is expected to get the FDA nod to market its own protease inhibitor for HCV telaprevir, to be marketed as Incivek, no later than Monday. Both the Merck and Vertex drugs will need to be taken in combination with the current standard of care, pegylated interferon and ribavirin.

Although the two drugs have never gone head to head in the clinic, telaprevir is widely considered to have a better dosing regimen and a slight safety and efficacy edge over Victrelis. As such, analysts have believed that Merck’s main advantage in the HCV market would be its ability to promote Victrelis alongside its own pegylated interferon PegIntron. Now, it will also have Roche’s sales force out there hawking Victrelis with Pegasys, as well.

No financials for the deal were announced, so its hard to say at this point how much Merck is giving up in its quest for a bigger piece of the HCV market. It’s also important to note that this is a non-exclusive pact, so time will tell whether Roche and Vertex establish a similar alliance.

The deal also allows Merck and Roche to “explore new combinations of investigational and marketed medicines.” As readers will recall, the ultimate goal is to eliminate the need for interferon and ribavirin, which have harsh side effects, and treat HCV using only a cocktail of pills. Roche and Merck each have promising small molecules against HCV in their pipelines: Merck has vaniprevir, an NS3/4a protease inhibitor in Phase II trials, while Roche has the polymerase inhibitor RG7128, the protease inhibitor RG7227, and the earlier-phase polymerase inhibitor RG7432.

    So Vertex has a superior compound, but Roche/Merck are still competitive because they have two inferior compounds that can now be marketed together by the combined sales forces from both companies? Pharma is going straight to hell.
