[Inventory] 2016 clinical medical seven test failure cases

1. Lilly: Alzheimer's disease drug Solanezumab

It is very difficult to find a cure for Alzheimer's disease. It takes a lot of money to develop a “killer” product, and Eli has put a lot of effort and cost into it. In November, Lilly's headquarters announced that its Alzheimer's disease drug Solanezumab failed in a phase III clinical trial, which is seen as a hope for treating Alzheimer's disease. This is the second failure of Solanezumab in the final clinical trial, the first failure occurred in 2012. This time, Eli Lilly chose to focus the indications for mild Alzheimer's disease and used the "delayed start" theory. However, clinical phase III data showed that the Solanezumab treatment group did not significantly slow cognitive decline in data performance compared with the placebo group. With the failure of Solanezumab, Lilly announced that it will lay off staff in the sales team in 2017 to solve Solanezumab's accounting problems.
