Healthy Paid Clinical Trials in Connecticut

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 study is seeking participants who: are females who are not able to give birth to a child of 18 years of age or older. are males of 18 years of age or older. have a BMI of 20.0 to 35.0 kg/m2. have total body weight of more than 50 kg (110 lbs). Participants in Part A will be randomly selected to receive either PF-07328948 or placebo (a pill that has no medicine in it). Participants in Part B will receive PF-07328948 as suspension and tablet form, both taken by mouth after food or during fasting. For a given participant in Part A, the total study is going to last up to about 12 weeks. This includes from the time of selection till the last follow-up phone call. The participants will be selected if they are fit for the study 28 days before the first dose of the study medicines. Participants who are selected will be admitted to the study site on Day -2 for around 19 days. Following discharge, participants will return for an on-site follow-up visit 7 to 10 days after receiving the final dose of the study medicine. The follow-up contact may be via a telephone call and will happen 28 to 35 days after the final dose of study medicine is given. For a given participant in Part B, the total study is going to last up to about 10-12 weeks. Participants will stay overnight at the CRU for 23 days (Sequence 1) or 18 days (Sequence 2), starting with check-in. In Sequence 1, there will be a minimum of 10 days between doses in Period 1 and 2, and at least 7 days between doses in Period 2 and Period 3. In Sequence 2, there will be a minimum of 7 days between each dose. Read Less

The purpose of the study is to investigate the effect of multiple doses of a proton-pump inhibitor (PPI) esomeprazole on the PK of vepdegestrant under fed conditions in healthy adult participants. All participants in this study will receive one dose of vepdegestrant alone by mouth in Period 1. In Period 2, everyone will receive esomeprazole by mouth once a day for multiple days. Participants will also receive one dose of vepdegestrant by mouth. The levels of vepdegestrant in Period 1 will be compared to the levels of vepdegestrant in Period 2 to determine if the PPI affects how vepdegestrant is processed differently in healthy adults.

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
