The purpose of this study is to determine linkage and retention in care in patients with HIV infection and reasons for loss to follow up Care in a High HIV-caseload Inner City Primary Care Practice in Sydney, Australia. The investigators hypothesise that patients attending HHMP will have higher rates of linkage and retention in care than the US HIV-infected population, and equivalent to Australian modelling.
The specific aim of this study is to document the pharmacokinetics of DAT receptor occupancy of OROS and immediate release (IR) MPH using PET scanning with C-11 altropane as the ligand. We hypothesize that the time to maximal receptor occupancy and the degree of receptor occupancy of immediate release (IR) MPH will be shorter and greater (respectively) than with an equipotent dose of OROS MPH.
The purpose of this study is to estimate phosphodiesterase 10A (PDE10A) occupancy in brain following a single dose of TAK-063.
The purpose of this study is to determine the brain cholesterol 24S-hydroxylase (CH24H) enzyme occupancy of TAK-935 after single oral dose in healthy participants using the positron emission tomography (PET) ligand [18F]MNI-792 and PET imaging and to determine the relationship of occupancy to TAK-935 exposure.
The primary objective is to confirm the target receptor occupancy of SK-1405 and to correlate receptor occupancy with SK-1405 dose and plasma concentration. The secondary objective is to assess the safety and tolerability of SK-1405 in healthy, Caucasian, male subjects.
The primary purpose is to study the occupancy at the α4β2 neuronal nicotinic receptor's (NNRs) and to determine the relation between plasma concentration of AZD1446 and the occupancy at α4β2 NNRs.
The specific aim of this study is to document the pharmacokinetics of dopamine transporter DAT receptor occupancy of OROS MPH and Metadate CD using PET scanning with C-11 Altropane as the ligand. We hypothesize that CNS DAT occupancy of OROS MPH will be greater than that of Metadate CD at 10 hours after administration.
The specific aims of this study are 1) to document the DAT receptor occupancy of armodafinil using PET scanning with C-11 altropane as the ligand and 2) to document the increased intrasynaptic dopamine produced by armodafinil using PET scanning with C-11 raclopride as the ligand. We hypothesize that DAT occupancy will be low with armodafinil; less than the DAT occupancy produced by therapeutic doses of methylphenidate. We also hypothesize that increases in intrasynaptic dop...
This phase 1 study will be conducted to examine the degree and duration of brain PDE2A enzyme occupancy /target engagement as a function of TAK-915 plasma concentration in order to guide dosing and schedule for future clinical studies in schizophrenia with TAK-915.
To answer the research question: "Would image-based modelling result in different clinical decisions as compared to clinical practice guidelines?", we will conduct a randomized controlled experiment in which we will compare the hypothetical decisions made by interventional cardiologists who are presented with imaging parameters currently recommended by clinical practice guidelines vs. hypothetical decisions made by interventional cardiologists receiving an expanded list of para...
A PET study using [11c]GSK931145 to characterise the exposure-occupancy relationship over time for GSK1018921.
The objectives of this study are to document the pharmacokinetics of the adequacy of DAT receptor occupancy d-MPH formulation in three doses (20 mg, 30 mg, and 40 mg) using PET scanning with C-11 Altropane as the ligand across a range of times. It has been estimated that MPH is effective when the average CNS DAT occupancy is 50% or greater. Focalin XR has been shown to be clinically effective in an analog classroom as early as 1 hour and as late as 12 hours. Therefore, it is ...
To assess the D1 receptor occupancy (D1 RO) in striatum after a single oral administration of PF-06412562.
The purposes of this study are to estimate the relationship of D2-receptor occupancy to plasma concentration and to assess the safety of OROS paliperidone.
The aim of this study is to relate pharmacokinetics of two different formulations of quetiapine to PET measured receptor occupancy in the brains of healthy subjects.
This study will provide information regarding dopamine D2/D3 occupancy related with clinical/adverse effects in older people with schizophrenia and schizoaffective disorder. The results of this study will also show an appropriate dose range in order to evade undesirable adverse effects while deriving therapeutic effects, which will directly serve to guide physicians in clinical practice. Furthermore, the findings of this study will elucidate mechanisms underlying older people's...
Despite all prevention efforts, many people in Australia continue to be infected with HIV. The Seventh National HIV Strategy 2014-2017 in Australia aims to work towards the elimination of HIV transmission by the year 2020. This project will evaluate a new additional way to lower people's chances of getting HIV. It will provide pre-exposure prophylaxis (PrEP) to people who are at high risk for HIV and evaluate what impact this new prevention approach will have on HIV in WA at th...
NSHDS (Northern Sweden Health and Disease Study) is an umbrella term for a prospective biobank with related survey data. The sample collection consists of three subcohorts, Västerbotten Intervention Programme (VIP), Mammography Screening Project (MA) and MONICA (MONItoring of Trends and Determinants in CArdiovascular Disease). The blood samples are stored at the Northern Sweden Biobank.
An Open Label Positron Emission Tomography Study in Healthy Male Subjects to Investigate Brain DAT and SERT Occupancy,Pharmacokinetics and Safety of Single Oral Doses of GSK1360707, Using 11C- PE2I and 11C-DASB as PET Ligands
GSK1360707 is a potent re-uptake inhibitor of the neurotransmitters dopamine, norepinephrine and serotonin. This is a single dose PET study in healthy subjects.A final analyses of safety data following exposure to single oral doses, from the first time in human study, with GSK1360707 has demonstrated that the compound is well tolerated up to a dose of 150mg. This imaging study will be an open label, non-randomised PET occupancy study using healthy male volunteers. The degree an...
