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 studying people with idiopathic pulmonary fibrosis IPF or progressive pulmonary fibrosis PPF who have previously taken nerandomilast in another study. The aim is to assess how well patients tolerate long-term treatment with nerandomilast and to evaluate whether it improves lung function and delays worsening symptoms, hospital visits, or death. This open-label extension trial is sponsored by Boehringer Ingelheim and focuses on treatment over an extended period. Participants take nerandomilast tablets for up to 1 year and 10 months while continuing their usual pulmonary fibrosis treatments. The study involves a single treatment group receiving the drug, and no placebo or comparison groups. Regular visits with doctors help monitor health and collect data during this extended treatment phase. Throughout the study, participants undergo regular lung function tests and health assessments to track any adverse events and changes in lung capacity. The main outcome measured is the occurrence of any adverse events for up to about 99 weeks. Secondary outcomes include changes in forced vital capacity and time to worsening of disease symptoms or hospitalization. The study includes ongoing safety monitoring with a total participation time of up to nearly two years.
