Indian authorities sign an MoU for a data and skill-sharing partnership between ICMR and IDDO
The Indian government’s Union Cabinet, chaired by Prime Minister Shri Narendra Modi, has approved a Memorandum of Understanding (MoU) between the Indian Council of Medical Research (ICMR) and the Infectious Diseases Data Observatory (IDDO), based at the University of Oxford.
The MoU will build a partnership both in and beyond data and skill-sharing and support capacity development with India’s scientific research community. It will ensure that data collection is compliant with international standards and regulatory requirements. Both ICMR and IDDO will exchange and share ideas on emerging infections and three vector-borne diseases in the elimination phase: malaria, visceral leishmaniasis, and filariasis.
Working together, both parties will support and develop best practices for data management, data documentation, data sharing and the development of equitable governance frameworks. The partnership will also explore opportunities for collaboration on research programmes and develop a three-year work plan on capacity strengthening, an exchange of research fellows, training on data management and statistical analysis.
Professor Philippe Guérin, Director of IDDO, said: “We are delighted to partner with the Indian Council of Medical Research and look forward to sharing expertise and strengthening our collaboration. Recent major public health events have shown just how effective shared knowledge and skills can be, and how crucial it is for the international scientific research community to continue to work together ever more closely. This partnership provides early career researchers with a fantastic opportunity to enhance their skills and improve treatment outcomes for affected communities.”

Estimating the proportion of relapse following treatment of Visceral Leishmaniasis: Meta-analysis of published studies
A meta-analysis aimed at estimating the proportion of relapse during the study follow-up period following treatment of Visceral Leishmaniasis (VL)
Analysis is ongoing with expected completion of the research activity by March-2022. Publication is expected by mid-2022 and dissemination of results will follow.
Visceral Leishmaniasis (VL) is a vector-borne disease transmitted by sandflies and caused by protozoan parasites of the genus Leishmania. An estimated 50,000 to 90,000 new cases of VL occur worldwide annually. The disease is fatal if untreated. The ultimate endpoint of parasitological efficacy is defined as the absence of relapse within the follow-up period after achieving initial cure upon the completion of treatment. Most clinical efficacy studies adopt a 6-month follow-up post-treatment to capture relapsing cases. Relapses after 6 months have been reported in observational cohorts leading to suggestion that a longer follow-up period may be warranted [1].
This project aims to quantify the proportion of relapses observed in VL patients at 6 and 12 months of follow-up after treatment with an antileishmanial drug. The specific objectives are:
- To estimate the proportion of relapses observed in VL clinical trials stratified by drug regimen, geographical region, follow-up duration, and mg/kg drug dosage administered
- To estimate the proportion of relapses captured at 6-months and at 12-months in studies with a follow-up duration longer than 6 months
This research will utilise data from the studies indexed in the IDDO VL living systematic review of all published clinical studies.
The following inclusion criteria is adopted:
- Studies with at least 6 months of post-treatment follow-up period
- Studies that aimed to capture relapse during the post-treatment follow-up period
The following studies will be excluded
- Studies with unclear information regarding the follow-up duration
- Studies not reporting the number of patients who were initially cured
- Studies that enrolled patients with HIV co-infection
Data on the following aspects of the included studies were extracted: study design, location, publication year, age range of the participants, total number of participants enrolled including the number of patients achieving initial cure, relapse. When reported, the number of the patients with these outcomes were extracted for each of the following time-interval: within 6 months of post-treatment follow-up, between 6-12 months or after 1 year of follow-up. The proportion of patients with relapse will be combined using random effects meta-analysis after applying logit transformation. The pooled estimates will be presented together with the associated 95% confidence intervals (95% CIs) and sub-group meta-analyses will be undertaken to explore potential sources of heterogeneity.

Our work
IDDO is working with the visceral leishmaniasis (VL) research community to collate global data and deliver robust science to address knowledge gaps and save lives with better treatment. The platform aims to facilitate pooled analysis of individual patient data (IPD) to answer the research questions of key interest to the VL research community.
A living systematic review
IDDO has found that data exists on more than 35,000 patients enrolled in over 150 trials in the past 20 years. This is captured in the VL Surveyor, an interactive tool that maps VL clinical trials and provides a clear visualisation of the research landscape.
This scattered but rich resource informs knowledge gaps in treatment optimisation that could influence future research. However, usually only summary statistics are available from publications, with results often not reported in a standardised and statistically comparable manner across different trials. This makes comparative analysis of efficacy between drugs, regimens and regions almost impossible.
A harmonised database of VL clinical trials
IDDO has assembled a harmonised database of VL clinical trials containing over 14,000 IPD, representing nearly one-third of the published sample size. Study groups investigating key research questions using the combined IPD have been launched in collaboration with data contributors and research experts.
Case report form for uncomplicated VL
In collaboration with the VL research community and partners including DNDi, IDDO has developed a freely-available case report form annotated to CDISC standards for uncomplicated VL. The case report form provides a flexible standard for use by VL researchers in clinical trial research.
Study groups
IDDO facilitates collaborative Study Groups to undertake individual patient data meta-analyses to answer specific research questions about visceral leishmaniasis (VL) treatments. Working together, and combining data from different regions and populations, is improving our understanding of the disease, and will advance research and subsequent drug development.
Systematic reviews
Our global collaborations have produced systematic reviews investigating critical areas of concern surrounding VL treatment and clinical trial research.

Open call to join new studies launched by the VL research community
Two new Study Groups, a collaboration between IDDO and the global visceral leishmaniasis (VL) research community, have been formed to answer specific research questions about treatments. They will undertake individual patient data meta-analyses using datasets from multiple studies, across sub-populations of interest, to help explore sources of between-study heterogeneity in therapeutic responses. Colleagues from across the VL research community are invited to join.
One Group will explore Anaemia among patients with VL and haematological dynamics post treatment and aim to characterise the haematological parameters at baseline and during the initial treatment and in the ensuing follow-up period using individual participant data hosted at IDDO VL data platform.
The other will look at Host, parasite, and drug determinants of therapeutic responses. There is a marked regional heterogeneity in therapeutic response against antileishmanial therapies in VL. Single dose Liposomal Amphotericin B remains the current first line therapy in the Indian subcontinent due to the emergence and evolution of drug resistant parasites against pentavalent antinomy (PA). However, PA in combination with Paromomycin has demonstrated a high efficacy in Africa and continues to be used as a first line therapy. Such heterogeneity in therapeutic responses has been thought to arise due to regional differences in parasite sensitivity/susceptibility. The importance of host and drug parameters as a determinant of observed differences in clinical response demand further investigations.
Both Study Groups will be co-led by Dr Prabin Dahal and Dr Sauman Singh. Colleagues from the VL research community interested in joining the Study Groups should email vl@iddo.org for more information.
Prabin Dahal, one of the study co-leads remarked: “Individual participant data (IPD) meta-analysis is increasingly recognised as a gold-standard method for evidence synthesis. It allows a more thorough and flexible analysis to be undertaken that would otherwise not be possible through published aggregate data. For example, the number of relapses in any single trials are few. Pooling IPD from several studies would allow us to explore the host, parasite and drug determinants of relapses which can be used to inform optimal case management. These study groups are therefore a unique opportunity for the global VL community to answer some of the long standing questions related to disease and the drugs.“
VL, also known as kala-azar, is transmitted to humans through the bites from infected female phlebotomine sand flies. If left untreated, it is fatal in 95% of cases. Globally, it is estimated there are up to 22,000 new cases of VL each year which occur in Brazil, Ethiopia, India, Kenya, Somalia, South Sudan and Sudan.
IDDO is a scientifically independent, multi-disciplinary coalition of the global infectious disease community. It is unique among data-sharing initiatives in taking many different types of data and standardising these to create larger-scale datasets to enable global research collaborations to pose new scientific questions.
