Healthy Paid Clinical Trials in Connecticut

The purpose of this study is to compare multiple formulations of PF-07220060 in terms of their uptake into the blood stream. The study will assess the effects of food and Rabeprazole on the uptake of PF-07220060. Rabeprazole belongs to a type of medications called proton pump inhibitors. In reality, some patients may take both PF-07220060 and rabeprazole together. This study is seeking participants that are: - Healthy male or female aged 18 to 65 years Participants in this study will receive PF-07220060 once or twice by mouth. The participants may receive different tablets for PF-07220060. Some participants will take a meal before receiving PF-07220060. In addition, some participants will take rabeprazole by mouth for 7 days before taking PF-07220060. The study will compare experiences of people receiving different formulations of PF-07220060. Experiences of people taking food and rabeprazole with PF-07220060 will be compared to those on PF-07220060 alone. This will help understand how much PF-07220060 is taken up into the blood. It will also help understand how meal and Rabeprazole medicine changes the uptake of PF-07220060 into the blood. Participants will take part in the study for a maximum of 74 days. During this time, they will have to stay onsite for 5 to 13 days. There will be up to 2 onsite study visits. Read Less

Subjects will enroll in one of the 2 cohorts, will have a baseline PET/CT scan, will receive a single dose of ITI-1284, and undergo one postdose PET/CT scan. Read Less

This research study is designed to look at the involvement of the glutamate system and synaptic density in depression and bipolar disorder. Each participant will undergo a screening appointment to determine study eligibility. Thereafter, the study will take 2 or 3 visits depending on schedule availability and will consist of a combination of one magnetic resonance imaging (MRI) or functional magnetic resonance imaging (fMRI) scan, one proton magnetic resonance spectroscopy (MRS) and/or one C13 MRS scans, and up to two positron emission tomography (PET) scans. Participants will also participate in cognitive testing. Depending on camera time, staff availability and subject schedule, total study participation may last 1-2 months. Read Less

The purpose of this clinical trial is to learn if the study medicine (called PF-07976016) is safe and how it goes in and out of the body in healthy people. The study may also explore if PF-07976016 has the potential to interact with another medicine called midazolam. In addition, the study may explore how PF-07976016 goes into the body of people who have obesity. Read Less

This study has two parts: Part A and Part B. The purpose of Part A of this study is to learn about the safety, tolerability, and how PF-07328948 is processed by the body when multiple doses of PF-07328948 are given to healthy participants. The purpose of Part B of this study is to understand the amount of PF-07328948 that would be available in the body after taking a single pill. The amount will be compared to the amount of PF-07328948 in a suspension in healthy adults. Part B will be conducted if the results of Part A support further study of PF-07328948.

The iCaRe2 is a multi-institutional resource created and maintained by the Fred & Pamela Buffett Cancer Center to collect and manage standardized, multi-dimensional, longitudinal data and biospecimens on consented adult cancer patients, high-risk individuals, and normal controls. The distinct characteristic of the iCaRe2 is its geographical coverage, with a significant percentage of small and rural hospitals and cancer centers. The iCaRe2 advances comprehensive studies of risk factors of cancer development and progression and enables the design of novel strategies for prevention, screening, early detection and personalized treatment of cancer. Centers with expertise in cancer epidemiology, genetics, biology, early detection, and patient care can collaborate by using the iCaRe2 as a platform for cohort and population studies. Read Less

The main purpose of this study is to determine whether hippocampal synaptic vesicle density estimated by hippocampal [11C]APP-311/[11C]UCB-J binding in individuals diagnosed with cannabis use disorder (CUDs) improves with at least 4 weeks of confirmed abstinence from cannabis, in comparison to healthy controls (HCs). Furthermore, any change in synaptic vesicle density will be placed in functional context by measuring verbal memory, which is sensitive to hippocampal function, before and after at least 4 weeks of confirmed abstinence. Finally, the relationship between hippocampal [11C]UCB-J binding in CUDs with measures of cannabis exposure (e.g., age of initiation, cumulative lifetime dose) will be explored. Read Less

The aim of this study is to evaluate a new SV2A tracer, [11C]APP311, in healthy aging and neuropsychiatric disorders including psychotic disorders and cannabis use disorders. Read Less

In this study, the investigators hypothesize that THC alters the immunogenome in a cell type-specific fashion and alters cytokine production via epigenetic regulatory mechanisms and that these alterations differ between HIV-infected and HIV-uninfected host genomes. Read Less

The aim of the present study is to assess the availability of cannabinoid receptors (CB1R) in the human brain. CB1R are present in everyone's brain, regardless of whether or not someone has used cannabis. The investigators will image brain cannabinoid receptors using Positron Emission Tomography (PET) imaging and the radioligand OMAR, in healthy individuals and several conditions including 1) cannabis use disorders, 2) psychotic disorders, 3) prodrome of psychotic illness and 4) individuals with a family history of alcoholism, 5) Post-Traumatic Stress Disorder 6) Opioid Use Disorder using the PET imaging agent or radiotracer, [11C]OMAR. This will allow us to characterize the number and distribution of CB1R in these conditions. It is likely that the list of conditions will be expanded after the collection of pilot data and as new data on cannabinoids receptor function and psychiatric disorders becomes available. Those in the cannabis us disorder arm of the study will have a PET scan on at least three occasions: once while smoking as usual, once after 48-hours of abstinence from cannabis, and a final time after 4 weeks of abstinence. Additional scans may be conducted within the 4 weeks and the last scan may be conducted well beyond 4 weeks. Similarly, while most schizophrenia patients may get scanned just once, a subgroup of patients may get scanned more than once. For example to tease out the effects of medications, unmedicated patients may get scanned while unmedicated and again after treatment with antipsychotic medications. Similarly prodromes may get scanned while in the prodromal stage off medications, on medications and after conversion to schizophrenia. Read Less
