THIS CALL IS NOW CLOSED.
The Neglected Tropical Diseases (NTD) Support Center, a program of The Task Force for Global Health, with support from the United States Agency for International Development (USAID) through the COR-NTD grant, is soliciting proposals for the near-term development of diagnostic and new/alternative platforms for monitoring and evaluation of schistosomiasis (S. mansoni and S. haematobium) control/elimination programs.
The goal of this RFP is to produce diagnostic tools that can be used at the point of care on non-stool samples to reliably measure schistosomiasis control/elimination programs. The programmatic context and diagnostic parameters that tools funded through this RFP must meet are outlined in the new WHO Schistosomiasis Monitoring and Evaluation TPP.
Submissions must be received by January 31, 2022 in order to be considered.
NTDs are a diverse group of 20 diseases that affect more than 2 billion people in 149 countries. People affected by these diseases suffer from significant long-term disabilities such as visual, physical or cognitive impairments, social stigma, and sometimes even death. NTDs often prevent people from working or attending school, thus costing developing economies billions of dollars annually.
Some NTDs (including schistosomiasis) can be controlled through the annual administration of preventive chemotherapy to the entire eligible at-risk population via mass drug administration (MDA). For these diseases, control/elimination programs are based on a four-stage process:
- Mapping disease prevalence to determine if treatment is warranted and where it is needed
- Monitoring prevalence levels during treatment
- Stopping or reducing the frequency of treatment once prevalence has declined below a defined threshold
- Surveillance to ensure that disease prevalence does not increase again after a change in treatment frequency.
At each stage of this process, programs rely on the availability of accurate diagnostic tests and tools to make important decisions. Traditionally, schistosomiasis programs have relied on parasitological techniques for mapping disease distribution and for monitoring the progress of MDA. However, as programs progress, prevalence declines and the need for improved diagnostics comes into much sharper focus. The NTD community has traditionally underinvested in the development and improvement of diagnostic tests and tools with the result that the currently available diagnostic tools are not capable of fully supporting the needs of late-stage control/elimination programs.
To address this critical gap, the World Health Organization (WHO) launched a Diagnostics Technical Advisory Group (DTAG) which was tasked with reviewing and prioritizing diagnostic needs for NTD programs, defining use cases and target product profiles (TPPs) for needed tools, working with national NTD programs and implementing partners to support test development and validation, and providing WHO with guidance and recommendations on adoption of new tools. Disease-specific DTAG subgroups have now developed TPPs and use-case analyses that can be used by product developers to understand the specific needs and contexts of NTD programs.
In order to decide when mass treatment is warranted or whether treatment frequency should change, NTD control/elimination programs use population-based surveys to show that disease prevalence in a given area is likely above or below a certain threshold. The main strategy for schistosomiasis control is based on MDA of praziquantel to primary school age children, and in certain regions, high-risk adults as well. The working guidance for control programs is that communities with ≥ 10% prevalence among primary school age children should receive annual MDA.
The goal of this RFP is to produce diagnostic tools that can be used at the point of care on non-stool samples to reliably measure when prevalence is above or below a cutoff of 10% parasite prevalence in school age children. Communities remaining above 10% require annual MDA while communities below 10% that are not seeking elimination of transmission can reduce MDA frequency as long as < 10% prevalence can be maintained. However, the current lack of an accurate, sensitive and scalable test has hindered the development of strategies to achieve and maintain the goals of eliminating schistosomiasis as a public health problem. The test is also needed to track changes of prevalence above 10% to ensure that annual MDA is reducing overall prevalence. In some areas with a higher force of transmission, annual MDA is not sufficient to reduce baseline prevalence and more frequent MDA or additional interventions should be employed. But again, lack of a cost-effective, accurate and sensitive test has hindered the definition strategies that are consistently effective in high transmission areas.
Proposals can address tests and tools used previously in the global health context or new products which have never been tested before. Proposals must align with the needs and contexts outlined by DTAG SCH M&E TPP.
