Interesting, can't say that would have been my first guess at what they would do. No (direct) mention of the follow-on so I take it by ending the collaboration all other compounds return to InterMune.
I guess this won't change Dew's opinion of the compound's future :-).
ITMN—I interpret the news as Roche’s agreeing to pay $175M merely to be free and clear of contractual obligations stemming from the 2006 Roche-ITMN partnership for HCV protease inhibitors. Inasmuch as there are newer and better PI’s available, I doubt that Roche will advance ITMN-191 to phase-3.
Roche Holding AG said it had teamed up with emerging biotech firm Ascletis to develop and commercialise its investigational drug danoprevir in China for the treatment of the hepatitis C virus.
Under the agreement, Ascletis will fund, develop and manufacture danoprevir in greater China, including Taiwan, Hong Kong and Macau and will also be responsible for regulatory affairs.
Danoprevir is a first-generation PI that must be given with interferon and ribavirin and is active in genotype-1/4. Roche paid ITMN $175M for the worldwide rights to Danprevir in Oct 2010 (#msg-55244199); maybe Roche will eventually get a return on the investment.
