Community-Based Model for Delivery of Antiretroviral Therapy in Cambodia

The community-based ART delivery (CAD) model will build on the existing framework to engage community action, operationalized in the current Global Fund-supported project. Community Action Workers (CAW), who are assigned to ART centers and conduct outreach work, are well-suited to administer CAD scheme. KHANA and the project partners all have implementation roles in the Global Fund-supported project and established working channels with the CAW. While the previous experiences suggest the CAD model's effectiveness, implementing it in Cambodia requires adaptation to its specific local context. The proposed project will be implemented as an implementation study in nine ART sites and supported by a concrete evaluation plan. KHANA Center for Population Health Research will lead the research component. The project has three strategic areas and corresponding deliverables as follows: A. The development of a locally-fitted model: bringing ART closer to the people living with HIV B. The research: formulation, evaluation, documentation, and dissemination of the evidence, knowledge, and lessons learned C. The scale-up: advocacy for the SOP development to replicate/scale-up the CAD model The project will benefit a wide range of stakeholders. The approximately 2,000 ART clients enrolled in the nine selected clinics will face less cost, time, and discrimination, which will also benefit their families. The clinics will have a reduced workload on site, and they would be able to improve the quality of care for the visiting clients. The Cambodian health system will obtain a CAD model tailored to the country's local context and develop Standard Operating Procedures for the scheme with readily involved stakeholders. The scale-up of the model will benefit all other ART clinics and clients in the country. The 36-months project starting from June 1, 2019, will include six months of start-up and baseline assessments, 24-month intervention, and six-month evaluation.

30-to-90 Day Challenge: Effects of Alcohol Cessation on Health Outcomes

The objective for this project is to determine whether how certain behavioral and health functions change in persons with heavy drinking when they stop (or reduce) drinking for 30 days, and whether changes continue for up to 90 days. The study will also identify barriers and facilitators related to drinking reduction. The project will focus on clinical comorbidities including HIV disease control, cognitive and brain function, liver abnormalities, and chronic inflammation. The study teams propose to enroll 140 HIV+ and 40 HIV- adults with heavy drinking, and then use Contingency Management (CM) with financial incentives to encourage participants to maximally reduce alcohol consumption for 30 days. Participants will be required to wear an ankle biosensor (SCRAM monitor) at all times, which is used to monitor participants' drinking behavior. At 30 days, participants will complete a full day of follow-up, including cognitive testing, neuroimaging, blood testing, liver Fibroscan, and questionnaires. Many participants will also provide a stool sample for gut microbiome assessment at each time point. At 30 days, participants will participate in a motivational interview to discuss perceived benefits and obstacles to drinking reduction, and most participants will continue CM to 90 days (but can opt out at this point). Participants will complete another full-day assessment at 90 days, at which point persons may choose to drink or not on their own (no more CM). A final assessment will be conducted at 12 months. This A-B-A design will enable us to clearly identify whether alcohol effects on cognition and brain function are reversible in the context of HIV, and analyze specific cerebral and systemic pathophysiological factors contributing to these effects. The inclusion of HIV- adults will enable subgroup comparisons of alcohol reduction effects in the context of HIV vs. no-HIV. These HIV-negative participants will be recruited from the same settings as our HIV+ participants, and will include a similar proportion by age, race, and gender as the HIV+ participants. The study team will use information from the MI data and our other assessments to elucidate factors that predict both short term (during CM) and long-term (1-year) alcohol reductions, and study how changes in alcohol consumption affect important HIV clinical outcomes that will be monitored over time.

Alignment of PrEP Use With HIV Risk in Young Women and Men

Oral pre-exposure prophylaxis (PrEP) is a recommended component of combination HIV prevention and its availability is rising through demonstration projects and full-scale national programs. In sub-Saharan Africa, young women are a priority population for HIV prevention and targeted to initiate PrEP, given their high HIV incidence rates and promising success from a strategy that can be used without the engagement of male partners. A key question in the field is whether young women using PrEP have ongoing HIV risk and adhere to PrEP sufficiently to have protection from HIV when they have condomless sex with HIV-infected partners. The only true way to know whether a heterosexual woman is sexually exposed to HIV or has a partner with high HIV risk is to test for HIV and STIs in her male partner(s) and quantify HIV viral levels, if any are detected. Yet engaging men in clinic-based HIV testing is challenging. More recent efforts have focused on using HIV self-testing kits to respond to demands on men's time and reluctance to seeking preventive healthcare. The availability of PrEP also provides a new incentive for men to test. By leveraging an ongoing study of bone health with concurrent use of PrEP and injectable DMPA (often known as Depo Provera® or depot medroxyprogesterone acetate), we have opportunity to engage a new cohort of young men and objectively measure HIV and common STIs in these young men and link the results to women's use of PrEP. The primary objective of this study is to determine whether young women's adherence to PrEP aligns with the HIV status and risk of their male partners. To address its primary objectives, this study will leverage: 1) an ongoing study among young women and 2) a novel cohort of young men who are current sexual partners of the young women in the ongoing study to objectively measure PrEP use, HIV, and HIV factors related to HIV risk. This study will provide a framework for understanding how and when young women and men decide to take PrEP, estimate the proportion of women that are benefitting from HIV protection when they have male partners with or at high risk of acquiring HIV, and provide a novel opportunity to engage young men in PrEP delivery and as supporters of women's PrEP use.

HIV-1 Infected Patients, Phase II Trial, Dual Combination Doravirine/Raltegravir Open Label

The objective of antiretroviral therapy (ART) is the maintenance of HIV viral suppression, the optimal condition to prevent disease progression, to optimize immune restoration, to prevent the development of viral resistance and to reduce viral transmission. Antiretroviral therapy has to be maintained long life over decades in the absence of strategies for HIV cure. This is why the long-term cumulative toxicity of ARV drugs is a major issue. Indeed as a consequence of potent ART strategies, in 2011 over 88% of patients on ART in the French Hospital database (ANRS CO4 FHDH) achieved viral suppression with HIV-RNA plasma viral load < 50 copies/mL and nearly 60% had CD4 > 500/mm3. As a consequence of massive reduction of mortality and morbidity related to HIV, infected patients are aging with 40% of patients over 50 years of age in the ANRS CO4 FHDH. The current standard-of-care for antiretroviral therapy consists in a triple drug combination with two nucleoside reverse transcriptase inhibitors (NRTIs) plus either a non-nucleoside reverse transcriptase inhibitor (NNRTI), a protease inhibitor (PI), or an integrase inhibitor (INSTI). NRTIs and PIs have been associated to cumulative long-term toxicity such as bone and renal disorders related to tenofovir and increased cardio-vascular risk with PIs. In general population, aging is associated with well-known comorbidities such as bone demineralization, increased incidence of cardio or cerebrovascular disease, diabetes, renal dysfunction. HIV infected patients are at a greater risk for such abnormalities. Another crucial concern is the high probability of drug-drug interactions in HIV-infected patients, between ART and comedications. Alternative strategies are needed, which must address the following questions: how to maintain the control of HIV viral replication while minimizing the occurrence of long-term clinical and metabolic complications, and minimizing the risk of drug-drug interactions? This study is an open label, randomized, switch study over 96 weeks in which virally suppressed patients on a stable combined ART regimen will be randomized (2:1) to an immediate switch to doravirine/raltegravir (immediate switch group) or to the maintaining of their current ART followed by a switch to doravirine/raltegravir at W48 (delayed switch group). Patients will be followed during 96 weeks.

Optimisation of Care in Vulnerable HIV Infected Individuals

Antiretroviral therapy is currently the only way to control HIV disease progression in HIV infected subjects and to prevent transmission. However a sustained virological control through antiretroviral therapy is requested for these objectives. There is currently 8-10% of patients who failed therapy for many reasons other than virological resistance including social unstability, psychiatric disorders, migrant status, drug or alcohol addictions. Because many of these vulnerabilities can be managed and patients helped for following adequately cares and treatments, study team designed the OPTICARE Program to help reduce impact of the patients' vulnerabilities. The OPTICARE study is designed as a prospective implementation interventional study which aims to improve retention in care among vulnerable HIV infected patients over 48 weeks. The OPTICARE program is a support program dedicated to patients either lost to follow up or in highly fraility situation that will offer an individualized care management to fill their gaps towards optimized care and control of viral replication. Our aim is, in patients virally failing in relation with poor adherence to care and treatment to test first part whether tracking proactively lost to follow up patients or detecting frail individuals at risk of lost to care is effective and secondly to evaluate the efficacy, the feasibility and the acceptability of an intervention tailored to each individual to get them to treatment success with viral suppression. In our context, a randomized approach would not be seen as ethical or possible in an environment where investigators need to evaluate such intervention as a pilot approach. Investigators therefore enrolled patients in a cohort population study OPTICARE program aim to actively identify vulnerable HIV+ population and promote optimal access to health care to this population using retention in care program in order to enable long term HIV infection control. The primary objective is to assess the feasability and the effectiveness of the OPTICARE program. The OPTICARE program aims to propose an individualized care to vulnerable HIV infected patients (UNAIDS/Second 90% goal) and to drive them to treatment success (UNAIDS/Third 90% goal) within a one-year period.
