Filter by:The aim of this study is to perform a performance evaluation of novel diagnostic tools for detecting malaria in malaria-endemic countries. At the beginning of 2022, FIND launched a call for innovation with the distinct aim to identify malaria innovations that have the potential to address the technical and operational limitations of current malaria RDTs, particularly in view of the emergence of P. falciparum parasites with hrp2/3 deletions, the need for improved tools to identify all Plasmodium species and/or the need for improved surveillance. This study will generate valuable data on the performance of these novel non-HRP2-based tests and inform FIND and developers on technical and operational assay optimization requirements for accelerated access of these tools to market.
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.
Since their introduction in the late 90's, rapid diagnostic tests (RDTs) have dramatically improved our ability to control malaria but proved insufficient to support elimination efforts because of their limited sensitivity, especially for P. vivax. In addition, the spread of P. falciparum parasites lacking hrp2 gene jeopardizes the long-term use of P. falciparum-specific HRP2-based RDTs. A partnership between Abbott, FIND, PATH, and the Bill and Melinda Gates Foundation (BMGF) is addressing these limitations by developing two novel malaria RDTs with improved pLDH detection: a P. falciparum-specific test targeting both the HRP2 and PfLDH antigens on a single test line (NxTekTM Malaria P.f plus Rapid Diagnostic Test Device), and a P. falciparum/P. vivax combo test additionally targeting the PvLDH antigen on a second test line (NxTekTM Malaria P.f/P.v. plus Rapid Diagnostic Test Device). These new combo tests with improved pLDH detection may provide added value compared to currently available malaria RDTs, especially in settings where current tests prove to be insufficient due to hrp2 deletion or high burden of P. vivax malaria. Abbott, PATH, and FIND will conduct a prospective evaluation of NxTekTM Malaria P.f plus and NxTekTM Malaria P.f/P.v plus RDTs in malaria-endemic countries to assess their clinical performance for detection of malaria and usability in their intended-use settings. This is in support of a submission for WHO Prequalification.The purpose of this synopsis is to describe key points of alignment in study design and conduct across the portfolio of studies.
Since their introduction in the late 90's, rapid diagnostic tests (RDTs) have markedly improved our ability to control malaria; yet they have inherent limitations which include low sensitivity in Plasmodium vivax detection and inability to detect hrp2/3 gene deleted Plasmodium falciparum parasites. In addition, the spread of P. falciparum parasites lacking hrp2 gene jeopardizes the long-term use of P. falciparum-specific HRP2-based RDTs. A partnership between RapiGEN, FIND, and the Bill and Melinda Gates Foundation (BMGF) is addressing these limitations by developing five novel malaria RDTs with improved pLDH and HRP2 detection. RapiGEN has also developed three novel malaria RDTs - BIOCREDIT Malaria Ag Pf/Pv (pLDH/pLDH), BIOCREDIT Malaria Ag Pf (pLDH/HRP2) and BIOCREDIT Malaria Ag Pf (pLDH) - to address these drawbacks. The BIOCREDIT Malaria Ag Pf/Pv (pLDH/pLDH) is a combo test that detects P. falciparum and P. vivax on a single device. BIOCREDIT Malaria Ag Pf (pLDH/HRP2) targets both PfLDH and HRP2 antigens in P. falciparum; and BIOCREDIT Malaria Ag Pf (pLDH) has improved detection of pLDH in P. falciparum. In countries with circulation of hrp2/3 deleted P. falciparum malaria parasites or high P. vivax burden, these improved RDTs may be invaluable in malaria elimination. This study is a prospective and retrospective evaluation of RapiGEN's BIOCREDIT Malaria Ag RDTs in malaria-endemic countries to assess their clinical performance for detection of malaria. The purpose of this study is to provide a high level outline of the study design and conduct to support the collation of a data package for WHO Pre-Qualification proposed study.
This concerns a single-center prospective interventional cohort study. Laboratory-confirmed COVID-19 patients will be asked to donate blood at at least two different timepoints. This will allow us to investigate T and B cell evolutions during the course of infection and recovery. The expected duration of the study is four months or the total duration of the SARS-CoV-2 circulation in Belgium (whichever is shortest).
