Healthy Paid Clinical Trials in California

The purpose of the study is to learn how different forms of a study medication called danuglipron are taken into the blood in healthy adults. Read Less

This is phase 1 single cohort study evaluating the effects of N-803 administration on mononuclear cells (MNC) collected from healthy donors undergoing a procedure called apheresis. Read Less

The global aim of this study is to investigate how the human microbiome changes from baseline with commonly used topical medications such as topical antifungals, low to mid potency topical steroids and emollients. The specific aims are as follows: Investigate whether ketoconazole cream, a commonly used topical antifungal, causes alterations in the human skin microbiome with short-term use. Investigate whether desonide 0.05 % ointment, a commonly used low potency topical steroid, alters the human microbiome with short-term use. 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

This study will assess comparative bioavailability and effect of food on a prototype fixed-dose combination (FDC) of Bemnifosbuvir (BEM) and Ruzasvir (RZR) in healthy subjects Read Less

We will sample intestinal microbiota using a microbiome sampling capsule in Healthy, Irritable Bowel Syndrome (IBS), and Functional Gastrointestinal Disease. Read Less

This is a first-in-human (FIH), randomized, placebo-controlled, double-blind, single ascending dose (SAD) study to assess the safety and tolerability of VIS954, a monoclonal antibody, in healthy adult male and female participants. Read Less

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 5-part study. The study duration will be approximately 60 days for Part A and approximately 90 days for Parts B, C, D, and E. Read Less

The norepinephrine-producing locus coeruleus (LC) is thought to be central to a wide array of cognitive functions, like attention and goal pursuit, and has been implicated in dysfunctions including attention deficit hyperactivity disorder and schizophrenia. The goal of this proposal is to develop methods that permit measurement of activity in the human LC. Because the LC is small and located in the pons, the Investigators will use high resolution magnetic resonance imaging techniques tailored to the brainstem environment, including neuromelanin-sensitive images shown to delineate the LC, combined with pharmacological manipulation to confirm the location of functional activity.

The purpose of this study is to determine whether personalized lifestyle coaching minimizes the negative impact of circadian disruption on performance and recovery in emergency medicine physician trainees during night shifts. Read Less

To compare the physiological and psychological effects of psilocin taken orally by pill or sublingually by dissolving a tablet under the tongue to those of psilocybin taken by pill in healthy adults. Read Less

This study will investigate the how the cerebellum is involved in speech motor learning over time and short-term corrections in patients with cerebellar ataxia and healthy controls. This will be accomplished through three approaches: behavioral studies, magnetic resonance imaging (MRI), and transcranial magnetic stimulation (TMS). During behavioral studies, participants will be asked to speak into a microphone while their voice is played back over earphones, and to do other speaking tasks. MRI will be acquired to perform a detailed analysis on brain function and anatomy related to speech and the cerebellum. In healthy controls, TMS will also be performed to temporarily disrupt the cerebellum before, during, or after the participant performs speaking tasks. Patients with cerebellar ataxia and healthy volunteers will be asked to complete behavioral studies and/or MRI; healthy volunteers may be asked to additionally participate in TMS. Read Less
