The main objective of the study is to assess the safety and tolerability of AMG 378 as single or multiple doses in healthy participants. Read Less

The purpose of this study is to assess the safety, tolerability, and pharmacokinetics (PK) of AZD8965 via single and multiple ascending doses in healthy participants (including Japanese and Chinese participants), and to assess the effect of food on the safety, tolerability, and PK of orally administered AZD8965.

This study will assess the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of AZD2389 following single and multiple dose administration (SAD/MAD) to healthy participants. Read Less

To support optimal behavior in daily life, goals and responses following emotional events should ideally incorporate not only the valence and intensity of prior emotional episodes but also their temporal features, such as the relative duration of positive vs. negative attributes. However, how specific brain regions contribute to the integration of temporal and emotional information and promote goal-directed response remains unknown. The goal of this study is to examine how specific brain regions track both emotional and temporal information of dynamic emotional events to inform other related brain regions to guide goal-oriented and context-appropriate actions. The investigators will scan healthy human participants using functional MRI (fMRI) while they view emotional image sequences and track the associated emotional and temporal (duration) information, and act accordingly. The investigators will employ multivariate patterns analysis and pattern similarity analysis to identify brain regions that represent (can decode) emotion, time, and their combined signals, as well as brain regions that represent the associated action goal. In addition, to infer the causal contributions of these brain regions in forming task-relevant representations (emotion, time, and action goal), the same participants will be recruited to receive transcranial magnetic stimulation (TMS) in these regions.

One hundred twenty healthy participants, ages 21 to 70, who experience moderate-to-lower-than-average mental well-being will be evenly randomized into four different study arms, using a 2x2 factorial design. Depending on the study arm, participants will either receive an inactive placebo or up to 25mg psilocybin (oral dose), in one of two set and setting conditions; drug administration contexts that are predicted to modulate drug effects. The purpose of this study is to evaluate any interaction effects between an oral dose of psilocybin and the surrounding context (set and setting). Read Less

All participants will undergo baseline biopsies of subcutaneous abdominal adipose tissue for cellular/molecular profiling via snRNA-seq and metabolic/physiological assessments (insulin sensitivity, glucose tolerance, and β-cell function). Older obese participants will be randomized into three arms: lifestyle intervention (n=24), senolytics (n=24), or placebo (n=24). Read Less

The main purpose of this first-in-human study to investigate the safety of LY3839840 in single and multiple doses, and how it's processed in the body when given in different amounts. Read Less

In this study, researchers will learn more about a study drug called BIIB080. BIIB080 is currently a drug under investigation for treatment of Alzheimer's disease. The main question researchers are trying to answer in this study is how radiolabeled BIIB080 distributes in the brain and spinal cord. To help answer this question, researchers will use positron emission tomography (PET) scanner that can detect radiolabeled BIIB080 after a single injection of a small dose of radiolabeled BIIB080 (\[89Zr\]Zr-DFO-BIIB080) and a dose of BIIB080 together via an intrathecal (IT) injection in healthy volunteers. Researchers will also learn about the safety of injecting radiolabeled BIIB080 and BIIB080 together. Read Less

The purpose of this study is to evaluate the effects of lithium and valproic acid on the single-dose pharmacokinetics (PK) of KarXT and the effect of KarXT on the single-dose PK of lithium and valproic acid in healthy participants. Read Less

The goal of this clinical trial is to determine the safety, tolerability and effects of Nezavist in healthy adults. The main questions it aims to answer are: * What is the safety and maximum tolerated dose (MTD) of orally administered Nezavist formulated as a spray dried dispersion (SDD) in healthy volunteers? * What are the pharmacokinetics (PK) of orally administered Nezavist SDD and its major metabolite (DCUKA) across a range of doses in healthy volunteers? Researchers will compare the active drug (Nezavist) and a placebo (an inactive substance that looks like the drug) to see if there is any differences between the two groups to make sure Nezavist is safe to use in future studies for reducing alcohol consumption by individuals that have alcohol use disorder (AUD).
