Why AC Immune Stock Surged Today

Shares of AC Immune (NASDAQ: ACIU) jumped 15% on Thursday after the Swiss-based biopharmaceutical company released promising data from its early-stage study of ACI-35.030, an experimental vaccine for the treatment of Alzheimer's disease (AD). 

AC Immune's vaccine candidate elicited a "potent" antibody response against pTau -- a protein that scientists believe plays a part in Alzheimer's disease -- in all 32 patients in its Phase 1b/2a clinical trial. "These remarkable data show that ACI-35.030 is capable of generating unprecedented antibody responses against pTau in an elderly population," AC Immune CEO Andrea Pfeifer said in a press release.
