Innovating Epidemic Surveillance: GADx partners on HOLICARE

September 11, 2024

GADx, in partnership with an international consortium, is revolutionising healthcare in low- and middle-income countries through the HOLICARE project. HOLICARE is a groundbreaking initiative established to improve the diagnosis of respiratory tract infections (RTIs), addressing current challenges in low- and middle-income countries.


RTIs are a leading cause of death among infectious diseases worldwide (reference WHO). They are one of the major Poverty-Related Diseases (PRDs), representing 40% of deaths and 17% of cases reported in Sub-Saharan Africa with 2.4 million deaths caused by RTIs reported in 2016.

The project converges around four pillars: diagnostics, network and resources, academy, and access. While GADx plays a role in all pillars, our focus is on the development of lateral flow diagnostic tests for COVID-19, influenza, and respiratory syncytial virus, with the goal of having these tests transferred for manufacture in Sub-Saharan Africa.

A goal of the project is to have these tests conform to the REASSURED criteria1, namely Real-time connectivity, Ease of specimen collection, Affordable, Sensitive, Specific, User-friendly, Rapid and Robust, Equipment-free, and Deliverable to end-users. The development program considers each of these criteria.


Drs Yue-Hua Dou and Annelyse Duvoix attended the first annual HOLICARE Diagnostics Workshop in Addis Ababa, organised by the Armauer Hansen Research Institute. The GADx team presented on lateral flow development, with a hands-on workshop on lateral flow lamination.


The clinical team of GADx is leading the clinical trial for HOLICARE. This trial aims to investigate the clinical validation of innovative microfluidic-based technologies designed for the detection of Lower Respiratory Tract Infections. Spanning a duration of 3 years from the commencement of recruitment, the trial will encompass a cohort exceeding 1000 participants hailing from three African nations, Ethiopia, Uganda, and Senegal.


This exciting project is funded by the European Commission as part of the Horizon Europe Research and Innovation Programme, under Grant Agreement Nº 101057596, and executed by a dedicated project team comprising GADx and an international team of experts (see website for full details).


The team will travel to Senegal, Ethiopia, and Uganda for clinical trial preparation.

Over many years that GADx has been at the forefront of innovative lateral flow test development, we have forged close relationships with the leading service providers in antibody production. When necessary, we design the required immunogens for you, and our trusted antibody deliver the antibodies ready to go. Working with GADx brings the benefits of these established connections. 2. Early Development: Accelerating from Concept to Prototype The early stages of developing a lateral flow test often appear to be relatively straightforward but are critical and require foresight into final usability and use case. Eventual performance of the test will be defined by these first steps, so developers carry a huge responsibility to ‘get it right’. This is where an assay development partner can be critical for the overall project. Having access to a wide range of materials, methods and know-how helps to cut time for assay design and construction, delivering prototypes that work and will require little optimisation. We bring into the conversation considerations of material choice and availability, sample processing, manufacturability, and result capture – to ensure it delivers on the intended customer usage. There is no doubt about it, setting off on the right path will reduce the overall development time. Engaging GADx as your CRO streamlines reagent selection, assay optimisation, and prototyping, allowing your team to focus on core innovations instead of getting bogged down by technical challenges. Many early diagnostic projects face a steep learning curve when tackling complex targets. By leveraging GADx’s expertise, organisations can tap into proven workflows and methodologies, avoiding the delays and costs associated with trial-and-error. 3. Reducing In-House Burdens Managing multiple projects can easily overwhelm even well-resourced R&D teams. A CRO can help by taking on your project, effectively acting as an extension of your team. This helps balance workloads, ensures milestones are met, and allows your team to stay focused on their primary activities and for your product to flourish. Many companies underestimate the effort required for specialised tasks such as antibody screening , epitope mapping or end user feasibility. A CRO can manage these tasks, allowing your core team to focus on their strengths. This also prevents employee overload and increases overall productivity by enabling teams to work more efficiently. Additionally, GADx’s expertise extends beyond antibodies to device prototyping and design, including rapid prototyping using 3D printing to create custom housings that integrate sample collection and processing. By entrusting these specialised tasks to a CRO with a proven track record, you avoid the need for internal staff to face steep learning curves or struggle with unfamiliar methods. 4. Mitigating Risk with a Stage-Gated Approach A stage-gated approach ensures each phase of development is validated before moving forward, reducing the risk of costly errors. GADx provides structured oversight, especially during proof-of-concept and prototyping phases, to minimise risk and support data-driven decisions.

In the ongoing fight against Crimean-Congo Haemorrhagic Fever (CCHF), Global Access Diagnostics (GADx) has joined forces with the Liverpool School of Tropical Medicine and international experts to develop a rapid diagnostic test (RDT) tailored for use in endemic settings. Published in eBioMedicine , this research showcases a critical advancement in tackling one of the world’s most challenging viral threats. CCHF is a tick-borne disease with a mortality rate as high as 30%, and it disproportionately affects rural communities where access to medical infrastructure may be scarce. Diagnostics for CCHF rely on complex lab-based methods, leaving frontline health workers with limited tools to manage outbreaks effectively. Addressing this, the newly developed RDT provides a faster, simpler solution that could shift the paradigm of CCHF detection. What the Results Say—and Why They Matter The prototype RDT’s performance was rigorously evaluated in Türkiye and Iraq, delivering promising results: Türkiye : The test demonstrated a remarkable sensitivity of 90.4% and specificity of 96.2% in prospectively collected clinical samples. These figures not only meet but exceed the World Health Organization’s (WHO) benchmark for CCHF diagnostics. Iraq : While the sensitivity in retrospective samples was slightly lower at 71.7%, the specificity remained high at 92.5%. Importantly, the test achieved 100% sensitivity in high-viral-load cases (cycle thresholds ≤20), highlighting its effectiveness in the most urgent scenarios. The takeaway? This RDT could be a game-changer in the early detection of cases, enabling swift action to prevent the disease’s spread and save lives. GADx’s Role in Driving Innovation This achievement was due to the collaborative nature of the approach— and GADx’s contributions were instrumental in several key areas: Technological Expertise & Collaboration : GADx lent its deep knowledge in monoclonal antibody development and lateral flow test design to ensure the RDT was both reliable and adaptable. LSTM staff and PhD students were able to collaborate and join GADx in our laboratories for development. Optimisation and Training : The company worked closely with key opinion leaders and healthcare teams to refine the test, optimise its accuracy, and ensure smooth implementation in real-world conditions. Global Perspective : Drawing on its experience in diagnostics for underserved regions, GADx helped shape the RDT into a tool that fits the needs of the most vulnerable communities.What’s Next? Turning Potential into Reality While these results are exciting, the work is far from over. The team is already looking ahead to the next phases of development: Expanding trials to include diverse geographies, ensuring the RDT’s reliability across viral strains and settings. Adapting the test for whole blood samples, making it even more practical for point-of-care use. Conducting cross-reactivity studies to confirm specificity and rule out interference from other pathogens common in endemic regions. Planning for full-scale IVDR-compliant clinical evaluations of the design-locked device in endemic settings. The goal? A diagnostic tool that is not only effective but also affordable, scalable, and ready to meet the realities of rural healthcare. A Collective Step Forward in Global Health This collaboration highlights what’s possible when expertise, resources, and a shared commitment to global health come together. For GADx, being part of this effort is both a privilege and a responsibility—a chance to contribute to a future where diagnostics are no longer a barrier to health equity. The RDT may not solve every challenge posed by CCHF, but it represents hope: hope for faster diagnoses, better patient outcomes, and a stronger defense against future outbreaks. At GADx, we’re proud to be part of this story, and we remain committed to advancing diagnostics that make a difference where they matter most. GADx and LSTM would like to acknowledge funding from the NIHR HPRU for Emerging and Zoonotic diseases and The Pandemic Institute who made this programme possible.

Imagine a future where cutting-edge diagnostic tools are accessible to everyone across Southeast Asia, regardless of their economic status. This vision took a significant step towards reality at a recent workshop in Kuala Lumpur, where experts from across the ASEAN region gathered to tackle one of healthcare’s most pressing challenges. A Call for Collaboration in a Diverse Landscape The ASEAN region is a tapestry of diverse populations, varied healthcare systems, and complex regulatory landscapes. This diversity, while rich in culture, creates unique hurdles in providing accessible and affordable healthcare, particularly in diagnostics. Our discussions made it clear that no single entity can address these challenges alone. Collaboration isn’t just beneficial – it’s absolutely essential. Product Development Partnerships At Global Access Diagnostics (GADx) , we’ve been championing product development partnerships (PDPs) for years. I was thrilled to share our experiences during the workshop, particularly our successful collaboration with IPD Diatropix in Senegal. This partnership has brought vital diagnostic tools to low and middle-income countries, and I could see the excitement in the room as we discussed how this model could transform healthcare in the ASEAN region. Eye-Opening Insights As we advanced our discussions, several key insights emerged: 1. Local Solutions for Local Needs While global experiences are valuable, we need to tailor our approach to the unique contexts of ASEAN countries. It’s not about transplanting solutions, but adapting them. 2. The Regulatory Puzzle The diversity of regulatory systems across ASEAN countries is both a challenge and an opportunity. There’s a clear need for greater harmonisation, which could streamline product development and distribution across the region. 3. The Affordability Balancing Act We’re constantly grappling with how to make our diagnostics both accessible and economically viable. It’s clear we need to innovate not just in technology, but in our business models too. 4. Reimbursement Complexities The workshop highlighted the vast differences in reimbursement models across ASEAN countries, emphasising the need for flexible approaches to ensure widespread access. Read the full report here. Spotlight on Severe Dengue One project that got folks talking was our work on severe Dengue . With millions of cases reported annually in the region, there’s an urgent need for better triage tools. Currently, only 3-5% of Dengue cases become severely ill, but identifying these cases early is crucial. We’re working with partners across ASEAN to develop a test that can identify patients at risk of severe disease. This involves an exciting biomarker discovery process, which could revolutionise Dengue management. The potential impact is enormous, I was encouraged by the enthusiasm in the room. Tailoring Solutions to ASEAN Markets A key takeaway from the workshop was the importance of understanding local market needs. We explored whether the diagnostics we develop for US and EU markets would be suitable for ASEAN countries. Interestingly, we found that while the core technology might be similar, there’s a need for local clinical trials to ensure effectiveness in specific populations. The Singapore Factor A deeply intriguing aspect of our discussions was the role of Singapore. As the only high-income country in the region, Singapore presents both challenges and opportunities. While it may not fit the typical profile of countries needing affordable diagnostics, its technological expertise and research capabilities could be invaluable to the broader ASEAN initiative. Filling the Gap Left by Big Diagnostics Companies We discussed why major diagnostic companies often overlook the need for affordable solutions in low and middle-income countries. Their business models typically don’t align with providing low-cost diagnostics in these markets. This gap presents a significant opportunity for PDPs to make a real difference. A Broader Vision The workshop wasn’t just about discussing current projects – it was about looking to the future. We’re exploring the possibility of creating a more extensive product development network that could benefit multiple low and middle-income countries, extending beyond ASEAN to include regions like South America and parts of Africa. This approach could help us work smarter, not harder, maximising our impact across multiple regions. It would allow us to develop products that could be manufactured locally in different areas, ensuring affordability and accessibility while giving local partners control over procurement and pricing. Next Steps We’re already planning follow-up workshops to dig deeper into specific projects and partnerships. These include focused sessions on our UTI and Dengue projects, as well as broader discussions on creating a unified ASEAN regulatory system. Funding such ambitious projects is a key consideration. We’re exploring opportunities with organisations like the Islamic Development Bank, UAE sovereign wealth funds, FCDO, and the Bill & Melinda Gates Foundation. A United Vision for Healthcare I was deeply encouraged and motivated as I left the workshop. By bringing together such a diverse group of experts and perspectives from across the ASEAN region, we’re not just talking about change – we’re laying the groundwork for it. We’re helping create a future where high-quality, affordable diagnostics are accessible to all. I speak for everyone at GADx when I say, we’re proud to be part of this effort. We’re excited about the innovations and breakthroughs that lie ahead. Together, we can transform the landscape of healthcare in Southeast Asia, one diagnostic tool at a time. The future we imagined at the start of this workshop? It’s within our reach, and we’re rolling up our sleeves to make it happen. Want more information? Interested in partnering with us?

On world COPD day, GADx is delighted to introduce our prototype test, (Headstart), a remote patient monitoring platform measuring five biomarkers in urine. Headstart is being evaluated to identify early or confirm the first signs of exacerbation with sufficient reliability and clarity for the patient to know when to seek medical attention or not. Early recognition and prompt treatment can result in reduced hospitalisations and improved clinical and economic outcomes. COPD affects over 400 million people worldwide and is predicted to be the third leading cause of death by 2030. COPD is characterised by daily symptoms of breathlessness, cough and wheeze with persistent impairment in lung function tests. At times there is worsening of the symptoms leading to exacerbations. Exacerbations are caused by several triggers including viral and bacterial infections but also due to a series of smaller perturbations culminating in destabilisation of the disease. COPD exacerbations can be harmful because they can cause further damage to the lungs therefore, preventing an exacerbation from occurring can improve quality of life and reduce risk of death. Most measurements of inflammation in COPD have focused upon sampling blood or sputum at the time of the exacerbation compared to stable visits several weeks apart. These approaches have not led to an adopted test due to lack of sensitivity and specificity and challenges in obtaining the samples at times that could then alter management. The challenge is to develop near patient tests that can measure and deconvolute the heterogeneous inflammatory response that precede the clinical presentation of an exacerbation. GADx have partnered with a number of experts along the way ranging from statisticians, bioinformaticians App developers, reader developers, clinical teams, health economic specialists, funding institutions, we have collectively been able to make breakthrough progress in the development of this technology. Today, on World COPD day , we are proud to announce that our paper ‘’Artificial neural network risk prediction of chronic obstructive pulmonary disease (COPD) exacerbations using urine biomarkers’’ has been published in ERJ Open Research. Link to press release. Our findings suggests that the identified urine biomarkers are promising in discriminating COPD exacerbations from stable COPD, can be measured at home with a lateral flow reader and mobile technology and can identify biological changes as early as 7 days prior to a clinical diagnosis of a COPD exacerbation. Further trials are required to validate the test and demonstrate cost-effectiveness and improved health outcomes. Professor Chris Brightling from the University of Leicester, UK, which is part of the National Institute for Health and Social Care Leicester Biomedical Research Centre said: “It would be better if we could predict an attack before it happens and then personalise treatment to either prevent the attack or reduce its impact. We wanted to develop a predictive test that would act like a personal weather forecast of an impending flare-up. We need to do more work to refine the AI algorithm with data from a bigger group of patients. We hope this will allow us to create AI testing for COPD patients that will learn what is ‘normal’ for each person and forecast a flare up in symptoms’’ Dr Gita Parekh, Head of Respiratory at GADx commented ‘’Every COPD exacerbation leaves behind permanent, irreversible lung damage. Headstart is being evaluated to predict exacerbations by detecting biological changes before signs of symptoms and before patient damage has occurred. A test that can help to slow the rate of disease, keep those living with COPD stable and reduce the risk of serious health complications is game changing. We thank everyone who has been involved and supported us throughout the years, it has been a team effort, all working towards the same goal – improving the quality of life for people living with COPD’’

For global health, the need for effective diagnostics in resource-limited settings has never been more pressing. At the recent Point-of-Care Testing (POCT) Meeting in Leipzig , 130 industry leaders and innovators gathered to discuss the latest advancements in this critical field. Among the key topics was the REASSURED framework, a comprehensive approach to developing diagnostics that truly meet the needs of low and middle-income countries (LMICs). What is REASSURED? REASSURED stands for Real-time connectivity, Ease of specimen collection, Affordable, Sensitive, Specific, User-friendly, Rapid and robust, Equipment-free, and Deliverable. This framework, an evolution of the WHO’s ASSURED criteria, provides a roadmap for creating diagnostics that are not just technically sound, but also practical and impactful in resource-constrained environments. Breaking Down the Framework Real-time connectivity: The ability to transmit results globally in real-time is crucial. This feature enables rapid response to outbreaks and informed decision-making at both individual and population levels. Ease of specimen collection: The less complex and invasive the sample collection process, the more likely a test will be widely adopted and correctly used. Affordable: Cost remains a significant barrier to healthcare access in LMICs. Diagnostics must be priced appropriately for their intended markets. Sensitive and Specific: These traditional measures of test accuracy remain critical. High sensitivity ensures few false negatives, while high specificity minimises false positives. User-friendly: Tests should be simple enough for use by individuals with minimal training, expanding their reach beyond traditional healthcare settings. Rapid and robust: Fast time to result and the ability to withstand challenging environmental conditions are essential for tests used in the field. Equipment-free: Minimising the need for additional equipment increases a test’s portability and reduces barriers to implementation. Deliverable: Tests must be able to reach the people who need them most, often in remote or challenging locations. Applying REASSURED in Practice Dr. Kevin Land, Chief Development Officer at Global Access Diagnostics, emphasized the importance of this framework in his keynote address. “REASSURED isn’t just a checklist,” he noted, “it’s a holistic approach to diagnostic development that keeps the end-user and their environment at the forefront of our minds.” Dr. Land shared examples of how this framework is shaping the next generation of diagnostics. For instance, innovative approaches to sample preparation are making tests more user-friendly, while advancements in materials science are improving test robustness and reducing costs. The Impact of REASSURED Diagnostics The potential impact of diagnostics developed under the REASSURED framework is significant. By increasing access to accurate, timely diagnoses, these tools can: 1. Improve individual patient outcomes 2. Enable better resource allocation in health systems 3. Enhance disease surveillance and outbreak response 4. Contribute to global health equity Challenges and Future Directions While the REASSURED framework provides a clear roadmap, implementing it is not without challenges. Issues such as regulatory approval processes, manufacturing scalability, and sustainable funding models are not addressed by REASSURED. However, the future looks promising. Collaborative efforts between academia, industry, and global health organisations are driving innovation in this space. As one attendee at the POCT Meeting remarked, “The energy and creativity in this field are palpable. We’re seeing solutions today that we couldn’t have imagined a decade ago.” Conclusion The REASSURED framework represents a significant step forward in our approach to developing diagnostics for resource-limited settings. By keeping these criteria at the forefront of innovation, we can create tools that not only perform well in the lab but also make a real difference in the field. As we continue to face global health challenges, from infectious disease outbreaks to the rising tide of non-communicable diseases, REASSURED diagnostics will play a crucial role in building more resilient and equitable health systems worldwide.
