The devil is in the details, and key clinical trial results made that abundantly clear this week. Eisai and partner Biogen released the highly anticipated details of an Alzheimer’s disease study they had already deemed positive, after an initial failure.
In one sense, the study was the success they have claimed. A high dose of the drug appeared to have a positive impact on patients, compared to placebo. But as the investment community teased out the details that trickled out at a big Alzheimer’s disease meeting, confusion and handwringing reigned. The drug’s different doses didn’t perform in a predictable way. A complicated trial design and imbalances between different groups made it tough to draw conclusions. Add it all up and the details, as one biotech analyst wrote, “call the reliability of this result and any associated inferences into question.”
