Die Investoren hatten sich offensichtlich einen "besseren" Deal erhofft.
"In January, Chinook paid AbbVie (NYSE: ABBV) an undisclosed amount to acquire atresentan, a drug tested as a potential treatment for kidney disease in patients with chronic kidney disease and type 2 diabetes. AbbVie stopped a Phase 3 clinical trial in 2017 after reporting that the study was revealing fewer endpoints than expected. The company said at the time the decision had nothing to do with safety risks."
Chinook hat also einen Phase3 Produktkandidaten von AbbVie erworben, der weniger klinische Endpunkte erreicht hat als erwartet. Das sollte man stets im Hinterkopf behalten.
