• In early December 2025, Merck outlined fresh Alzheimer’s data for its investigational candidates MK-2214 and MK-1167 at CTAD and disclosed that MK-2214, a tau‑targeting antibody, received FDA Fast Track Designation, while also raising more than US$8.97 billion through a mix of senior and subordinated bond offerings.
