The purpose of this study is to compare two 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 All participants in this study will receive PF-07220060 once 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 two 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 71 days. During this time, they will have to stay onsite for 5 to 11 days. There will be up to 2 onsite study visits. Read Less

This study aims to examine the effect of cannabidiol (CBD) pre-treatment on brain microglial activation in healthy human subjects. Secondarily, this study aims to examine the effect of cannabidiol (CBD) pre-treatment on central pain-sensitization in healthy human subjects. Read Less

The purpose of this study is to longitudinally characterize and evaluate changes in synaptic density in the brain using novel positron-emission tomography (PET) scans; magnetic resonance imaging (MRI), and clinical laboratory markers associated with HIV-related injury in the central nervous system. This study will test hypotheses relating to the presence and mechanisms of aberrant brain structure at the synaptic level in living humans with virologically controlled HIV on antiretroviral therapy. To evaluate associations between PET imaging radiotracers [11C]UCB-J, a ligand for presynaptic vesicle protein 2A (SV2A), a vesicle membrane protein expressed in synapses, and PET [11C]PBR28 a measure of microglia function in the brain, the Yale PET center has developed an advanced approach of combining multiple distinct ligands in coordinated same-day PET imaging. Additionally, the study will evaluate the associations of this novel synaptic density marker with well-established clinical measures of neurocognitive performance and laboratory measures of blood and cerebrospinal fluid (CSF).

The overall goal of this protocol is to: Evaluate [18F]UCB-2897 as an α-synuclein targeted radiopharmaceutical. The primary objective is: • Confirm a specific α -synuclein signal with [18F]UCB-2897 in participants with PD and/or MSA relative to healthy volunteers Secondary and exploratory objectives are: Determine the safety and tolerability of microdose [18F]UCB-2897 Evaluate preliminary dosimetry of [18F]UCB-2897 Additional exploratory objectives are: Determine the pharmacokinetics / metabolism of [18F]UCB-2897 Determine the optimal imaging protocol for [18F]UCB-2897 Read Less
