This stock has climbed about 20% year to date, and the stock jumped 5.29% today on news related to its Alzheimer's disease clinical trials. Eli Lilly's developmental drug solanezumab didn't meet the two primary endpoints set for the study, but the new data released today showed that the therapeutic was able to slow down memory loss in early-stage Alzheimer's patients by 34%. While these results aren't unequivocally positive, this market move reflected hope that solanezumab could eventually become a treatment option for Alzheimer's patients. Eli Lilly stated that it will consider the next steps for this drug in the coming weeks, but its road to FDA approval looks long and winding -- and could involve additional clinical trials. After today's increase, Eli Lilly is perched near its 52-week high, but investors should be on the lookout for upcoming clinical results related to this developmental medicine.
