A Study of LY3971297 in Healthy Participants
Recruiting
The purpose of this study is to measure side effects of LY3971297 injection administered under the skin in healthy participants and obese participants with high blood pressure (BP). Blood tests will be performed to check how much LY3971297 gets into the bloodstream and how long it takes the body to eliminate it. This is a 7-part study. The study duration will be approximately 60 days for Parts A and F, and approximately 90 days for Parts B, C, D, E, and G.

A Study to Assess the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of AZD4144 as Well as the Impact of AZD4144 on the Pharmacokinetics of Rosuvastatin and Furosemide in Healthy Participants
Recruiting
This study consists of 3 parts: Part A, Part B and Part C. This study will compare the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of AZD4144 with placebo in healthy participants, in Part A and Part B. Part C of this study will investigate the possibility of drug-drug interaction (DDI) between IV AZD4144 and oral rosuvastatin and furosemide by evaluating the PK of rosuvastatin and furosemide when administered alone and in combination with single IV dose of AZD4144

LPFC Organization in Emotion-Duration Difference Estimation
Recruiting
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 region... Read More

Recruiting
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... Read More
