Sanofi is breaking it off with oncology partner Merrimack Pharmaceuticals, handing back full rights to MM-121, a treatment that has three times failed to hit the mark in midstage studies.
Merrimack Pharmaceuticals got roughed up when it went public back in 2012, then took it on the chin--twice--when one of their cancer drugs partnered with Sanofi failed two mid-stage studies.

But there's no indication that we're on the verge of, or will ever, return to the go-go years of the 1990s when biotechs more easily went public at lofty values. Here's the full report >>
