why did GILD drop their partnership with Achillion?
As mcbio noted, the GILD-ACHN partnership for ACH-1095 (not to be confused with ACH-1625, the drug in the news today) was restructured, not dropped. A relevant piece of background info is that ACH-1095 is a second-generation version of ACH-806, which was discontinued in 2007 due to elevations of creatinine (#msg-18754183).
