Each week, we like to take a moment to boil down the biggest news from the most influential companies in the pharmaceuticals industry, and tell our viewers what that news means for you. We call that segment our Big Pharma Roundup.

In this week's installment, Merck (NYSE:MRK) gave us an update on its Alzheimer's program last week, and now, Eli Lilly (NYSE:LLY) has given an update on its Alzheimer's drug solanezumab. The company plans to conduct further phase 3 trials for patients with a milder form of the disease, despite failures with the drug in other phase 3 trials, as the data suggests there may be some benefit for those patients.
