Clinical trials

Implementation and evaluation of a distribution program for low dead-space syringes/needles (LDSS/N) in Armenia, Georgia, and Tanzania, Egypt, Nigeria, Vietnam, India, Ukraine, and South Africa. This study aims to generate evidence on best practice LDSS/N distribution programs which will enhance acceptability and sustain high levels of LDSS/N uptake. People who inject drugs and access needle and syringe programs will be invited to attend up to three focus group discussion rounds (with 25 participants in each focus group round) to inform and provide feedback on a concurrent distribution program of LDSS/N. Throughout distribution, a cohort study will be run alongside distribution with 240 participants enrolled per country (with the exception of Nigeria, where 480 participants will be recruited) who will undergo HIV and HCV testing and answer surveys on their sociodemographic and behavioral status. Key informant interviews will also be held with participating staff and stakeholders to evaluate the feasibility and acceptability of this program. Primary outcomes assessed through this study include 1) community values and preferences for LDSS/N, 2) barriers and facilitators to accessing LDSS/N, 3) feasibility and effectiveness of the distribution program on increasing LDSS/N uptake, 4) model the potential public health impact and cost effectiveness of LDSS/N distribution in this setting.

The goal of this non-randomised, quasi-experimental, prospective comparative trial is to trial simplified care pathways for hepatitis C testing and treatment for people who inject drugs in Armenia, Georgia, and Tanzania. The main questions it aims to answer are: 1. What is the feasibility of implementing a hepatitis C simplified care and same-day treatment care model in community and harm reduction settings in the three study countries? 2. Does a same-day treatment initiation model involving only POC antibody tests (with a shortened read-time) increase hepatitis C treatment uptake and SVR12 outcome (cure) among people who inject drugs compared with a simplified care model involving POC antibody followed by a confirmatory RNA test? 3. What is the comparative cost-effectiveness between a same-day antibody only hepatitis C testing and treatment model and the simplified care model (POC antibody/confirmatory RNA test) model? Participants will: * be enrolled in a new simplified model of care in each country (Arm 1). After the enrolment target is met for Arm 1 (approx. 3-9 months into implementation) new participants will be enrolled into a same-day treatment trial, using presumptive treatment after a reactive POC test result at shortened read-time (5minutes) (Arm 2) * if in Arm 1, participants will commence SOF-VEL DAA treatment after receiving an RNA test to confirm current hepatitis C infection. They will then continue along the treatment pathway, returning for RNA testing 4-16 weeks after SVR12 to determine cure. * if in Arm 2, participants will begin SOF-VEL DAA treatment on the same day as the 5 minute RDT testing. They will then continue along the treatment pathway, returning for RNA testing 4-16 weeks after SVR12 to determine cure. Researchers will compare cure and participant retention rates between the two groups.
