Researchers are evaluating MK-2214, a study treatment designed to slow brain changes in people with early Alzheimers disease AD. AD is a form of dementia that causes memory loss, communication difficulties, and challenges in decision-making, affecting daily tasks. This phase 2 trial aims to determine if MK-2214 slows the spread of tau protein in the brain compared to a placebo, as well as to assess the safety and tolerability of MK-2214. Participants will be randomly assigned to receive either MK-2214 or a placebo through intravenous IV infusion every 4 weeks during the study. The study uses a parallel design with quadruple masking to compare the effects of the study drug versus placebo over a period of up to approximately 23 months. Both groups receive infusions on the same schedule to maintain the studys integrity. During the study, participants will undergo brain scans including positron emission tomography PET to measure tau protein levels and other assessments such as cognitive and daily living function tests. Researchers will monitor adverse events and treatment discontinuations throughout the study, which lasts up to about 26 months. These assessments help determine the impact of MK-2214 on disease progression and safety in individuals with early AD.

Researchers are evaluating whether retatrutide and tirzepatide can prevent major adverse liver outcomes in adults with metabolic dysfunction-associated steatotic liver disease MASLD who are at high risk based on non-invasive tests. This Phase 3 randomized controlled trial aims to assess these treatments compared to placebo in about 4,500 adults over approximately 224 weeks.
