Human Immunodeficiency Virus (HIV), hepatitis C (HCV), and syphilis are sexually transmitted and blood borne infections (STBBI) that affect millions of people worldwide and rates are rising in Canada. HCV and syphilis are curable, and HIV is treatable with virtually no risk of transmission to sexual partners when the infection is controlled, however, these outcomes require adequate testing. Unfortunately, an estimated 44% of Canadians living with HCV and 13% living with HIV are not diagnosed. These undiagnosed cases are the source of over half of new HIV infections. Furthermore, HIV-syphilis coinfection is common. Accessible testing forms a key pillar of an elimination strategy and acts as an access point for linking people to care. Community pharmacies are more accessible site for STBBI testing, compared to hospitals and doctors' offices. This is especially true for members of marginalized communities, some of whom are at higher risk of infection. The COVID-19 pandemic highlighted the need for low-barrier STBBI testing, as in-person healthcare services at doctors' offices and traditional screening clinics were scaled back. Pharmacies remained open throughout the pandemic. The APPROACH 2.0 study will assess the impact of a pharmacy-based testing program for HIV, hepatitis C, and syphilis in participating pharmacies in three Canadian provinces: Newfoundland & Labrador, Alberta, and Nova Scotia on finding new diagnoses and linkages with care. Participants will be offered point of care tests for HIV and/or HCV and/or a dry blood spot test which will test for HIV, HCV, and syphilis. These tests are easy to administer. Results from the point of care tests are available immediately during the pharmacy visit while participants will be contacted with dried blood spot test results when available (approximately 2 weeks). Participants with reactive tests are linked with confirmatory testing and care, and those with non-reactive results are offered preventative services including HIV PrEP (as indicated) and counselling. This study builds on a pilot study completed in 2017 (www.APPROACHstudy.ca).
This is a prospective, controlled, open-label, pharmacokinetic study. This study aims at studying the PK of sofosbuvir, ledipasvir and sofosbuvir metabolite (GS-331007) in HCV infected children with hematological Disorders. to develop predictive pharmacokinetic model for the 3 moieties in the studied population. In this study, patients in both treatment groups will receive 12 weeks of treatment with a fixed-dose combination tablet containing 400 mg of sofosbuvir and 90 mg of ledipasvir(SOF/LED) orally, once daily with food.
This study has two parts. Part A will assess the safety, tolerability and pharmacokinetics (PK) of AT-777 in healthy subjects. Part B will assess the safety, antiviral activity/efficacy and PK of AT-777 in combination with AT-527 after 8 weeks of treatment in HCV-infected subjects.
Hepatitis C (HCV) is a chronic infection with significant morbidity and mortality. The development of directly acting antivirals (DAA) has dramatically improved the cure rate of HCV treatment. People who experience incarceration are disproportionately infected and often involved in ongoing transmission of disease. However, despite availability of effective treatment, people who experience incarceration are often unable to access this curative therapy, and are often not readily engaged in medical care upon release. This perpetuates transmission and progression of disease in an incredibly high risk, marginalized population. Therefore, in order to effectively eliminate HCV, it is imperative that the epidemic of HCV in prisons is addressed, and that models of care are established for treatment of HCV in incarcerated individuals, both during and after incarceration. As such, the investigators propose a comprehensive model of care to engage incarcerated individuals in treatment of HCV upon release from prison. This care is provided in conjunction with collocated services to prevent HCV reinfection, including opioid agonist therapy. This pilot trial will demonstrate whether a comprehensive model of care can effectively cure HCV in recently incarcerated individuals, while simultaneously treating opioid use disorder and preventing HCV reinfection.
The purpose of this study is to prospectively evaluate the value of Optical coherence tomography angiography (OCT-A) for the of detection of suspected retinal complications With Sofosbuvir (Sovaldi) in Patients With Hepatitis C Virus Infection
This study will test the effects of an intervention to reduce substance use and related harms among people leaving rural jails or otherwise involved in the criminal justice system. This study will compare people in a health linkage intervention with people who will get overdose (OD) education. Everyone will take part in the baseline and follow-up surveys and receive OD education. Participants will be assigned to one of the two groups by chance based on when they are enrolled to the study and if their county is randomly assigned to an intervention or a comparison condition. By doing this study, the investigators hope to learn if providing linkage to health services along with HIV, hepatitis C virus (HCV), and overdose education to people leaving rural jails or otherwise involved in the criminal justice system will reduce substance use and related harms.
Data on the prevalence of hepatitis C virus (HCV) for other vulnerable groups in Madrid, such as homeless persons and migrants, are scarce, and it is now necessary to implement intervention and elimination plans. Vulnerable groups have poor access to healthcare and are therefore not systematically screened for HCV. On the occasions they are shown to be positive, subsequent follow-up in the health system and the possibility of cure are poor. The use of a mobile unit to approach vulnerable populations is essential for better characterization of risk behaviors and of the magnitude of HCV. The integration of healthcare personnel in mobile units enables counseling on prevention and intervention when needed. Primary objective Evaluate the impact of the HCV care cascade on vulnerable populations who gather at hot spots in Madrid (shantytowns, homeless shelters and places were street prostitution is practiced) by means of a multilevel outreach project. SURVEILLANCE: Active screening for HCV among vulnerable individuals in populations with a high prevalence of HCV will be carried out in hot spots in Madrid, namely, Cañada Real shanty town, mobile harm reduction units, institutions providing social assistance, public areas, homeless shelters and places where street prostitution is practiced. An agreement with the Madrid Council (MCC) is under way to provide social centers for HCV screening. A mobile unit will approach the hot spots following a predefined schedule. The mobile unit consists of a van adapted for the project and a car. HCV screening of vulnerable individuals will be performed by a nurse and an educator hired specifically for that purpose. Active HCV screening and prevention in vulnerable individuals should be a priority and a responsibility shared by both the MCC and the SERMAS (Servicio Madridleño de Salud). The investigators plan to establish an agreement with public health authorities to give continuity to this project and to carry out proactive HCV screening through integration with various centers and networks dependent on the MCC and SERMAS. The project will establish the foundations of integrated cooperation between an HCV clinic in a hospital setting and harm reduction units and other resources and networks dependent on the institutions mentioned above. As has been observed with other interventions, the functional objective of this project is to provide continuity of care from the institutions. Study Duration (in months) 12 months.
This cross-sectional survey will be conducted prospectively in 2 communes in the Battambang Province, Roka and Prey Khpos commune. The principal objective of the study is to compare HIV and HCV prevalence rates in three groups of subjects as follows: - Group 1: subjects living in Roka and Ambaeng Thngae villages where most of HIV and HCV cases were identified during the Roka outbreak in 2014-2015 - Group 2: subjects living in the other 4 villages of the Roka commune (Ta Haen I and II, Pou Batdambang, and Chhung Tradak) - Group 3: subjects living in selected villages from Prey Khpos commune 1,098 eligible residents will be selected using three-stage cluster sampling method. A structure questionnaire will assess the medical injection practices through face-to-face interview. The study will be conducted into two steps. The first step will be a prevalence study to assess HIV and HCV prevalence rates in three groups of subject; Group 1: subjects living in Roka and Ambaeng Thngae villages where most of HIV and HCV cases were identified during the Roka outbreak; Group 2: subjects living in the other 4 villages of the Roka commune (Ta Haen I and II, Pou Batdambang, and Chhung Tradak) and Group 3: subjects living in villages from Prey Khpos commune).The second step will be the phylogenetic study of HIV. The phylogenetic study of HIV will be performed ONLY if HIV prevalence rates among group 2 and/or group 3 is higher or equal to 0.7% (upper limit of confidence interval of HIV prevalence estimated in Cambodia)
The study will assess the safety and efficacy of AT-527 in combination with daclatasvir after 8 or 12 weeks of treatment.
