• Baxter International Inc., of Deerfield, Ill., said a Phase III study testing immunoglobulin did not meet the co-primary endpoints of reducing cognitive decline and preserving functional abilities in patients with mild to moderate Alzheimer's disease. Results, however, showed a positive, numerical difference in the change from baseline vs. placebo in cognition in a subgroup analysis, though the study was not powered to show statistical significance among subgroups. Based on those data, Baxter said it will reconsider the current approach for its Alzheimer's program and determine the next steps. The study, dubbed Gammaglobulin Alzheimer's Partnership, was conducted in collaboration with the Alzheimer's Disease Cooperative Study, a clinical trial consortium supported by the National Institute on Aging.

• Bristol-Myers Squibb Co., of New York, and Pfizer Inc., also of New York, said results from a prespecified subanalysis of the ARISTOTLE trial were published in Circulation, showing that the reductions in stroke or systemic embolism, number of major bleeding events and mortality demonstrated with Eliqus (apixaban) compared to warfarin were consistent across subgroups defined based on levels of International Normalized Ratio control in patients with nonvalvular atrial fibrillation. Eliquis is an oral direct Factor Xa inhibitor.
