NCT ID: NCT06356974 Not yet recruiting - Clinical trials for Human African Trypanosomiasis

Stop Transmission of Gambiense Human African Trypanosomiasis (STROgHAT)

STROgHAT
Start date: April 8, 2024
Phase: Phase 3
Study type: Interventional

This protocol describes both the epidemiological study which aims at assessing whether over a three-year period a zero prevalence can be achieved when implementing a screen & treat approach with acoziborole, as well as a nested clinical study aimed at generating further evidence on safety of acoziborole in gambiense human African trypanosomiasis (gHAT) seropositives individuals. The overall coordinator will be ITM. ITM will be fully responsible for the epidemiological study (study Part A), including cost effectiveness and evaluation of diagnostic tests. DNDi will be the legal sponsor of the nested safety clinical study (study Part B) and will ensure compliance with regulatory requirements and good clinical practices (GCP) for this part of the study. The investigators hypothesize that by systematically screening the populations of all endemic villages in a well-defined HAT focus and by expanding gHAT treatment to all seropositives, that it will be able to arrive at a zero prevalence over a three-year period. The objectives are to evaluate whether a strategy based on widened treatment for all parasitologically negative seropositive gHAT suspects with acoziborole can lead to interruption of transmission of T.b.gambiense in a mainland focus and to assess the safety of acoziborole in gHAT seropositve individuals and parasitologically negative.

Screen and Treat Implementation for HAT Control

Start date: January 1, 2024
Phase:
Study type: Observational [Patient Registry]

Human African Trypanosomiasis (HAT), or sleeping sickness, is one of the parasitic diseases targeted for interruption of transmission by 2030 by the WHO. The development of fexinidazole as treatment is a huge step towards this achievement; however, the diagnostic algorithm remains complex due to limited sensitivity and specificity of the available tests. A combination of serological screening and confirmation of infection through parasite visualization remains the preferred strategy, although it can be difficult to ensure its full performance in areas that are hard to reach or have limited access to electricity and other means. The present study would like to test an approach of ensuring treatment with fexinidazole of sero-suspects without confirmation of disease, among patients that consult fixed health infrastructures in the provinces of Maniema, Lomami and Tanganyika. This should enable access to gHAT treatment for patients living in hard to reach areas, actively seeking health care.

Assessment of Recombinant HAT-RDT Specificity

Start date: September 20, 2022
Phase:
Study type: Observational

Human African trypanosomiasis HAT, or sleeping sickness, is a tropical disease caused mainly by the parasite Trypanosoma brucei gambiense (gHAT). After a severe epidemic in the 1990s, the World Health Organization (WHO) now targets elimination of transmission of gHAT by the year 2030, which heavily relies on its diagnosis and treatment. Traditional screening tests (like CATT or rapid diagnostic tests (RDTs)) are based on the detection of antibodies against the parasite using native antigens, which are costly and dangerous to produce. New serological tests, using recombinant antigens, have been developed, but little is known about their field performance. The primary objective of this study is to assess the specificity of the newly-developed recombinant RDTs, since it will become very relevant as we move forward towards a screen&treat strategy. We will also compare the diagnostic accuracy and overall performance of iELISA and molecular testing.

Start date: June 20, 2022
Phase: N/A
Study type: Interventional

This study evaluates and compares the diagnostic specificity of 5 serological field tests for screening of the population at risk for human African trypanosomiasis due to Trypanosoma brucei gambiense.

Pharmacokinetic, Efficacy, Safety and Tolerability Study of a Single Dose of Acoziborole in g-HAT Paediatric Patients

OXA005
Start date: July 15, 2022
Phase: Phase 2/Phase 3
Study type: Interventional

Acoziborole has been studied in an open-label pivotal Phase II/III trial (DNDi-OXA-02-HAT) in the DRC and Guinea. As the numbers of reported cases diminish, resources for surveillance and specialised screening will also taper. This decrease, coupled with the loss of diagnostic skills and disease management expertise, will lead to a weak and less specialised HAT technical environment. The history of g-HAT has shown that outbreaks or re-emergence of the disease have already happened under different circumstances when surveillance was relaxed or simply because the populations at risk live in areas of political instability, limiting access to specialised care. Even with a steady decrease of reported incidence, no model can currently predict that HAT could not re-emerge. Although g-HAT is predominantly a disease of adults, children are also affected at diverse rates depending on the geographical and behavioural characteristics in the different areas of disease transmission. Hence efforts are needed to develop a paediatric formulation from a new generation of oral HAT treatments.

Safety and Tolerability Study of Acoziborole in g-HAT Seropositive Subjects

OXA004
Start date: December 30, 2021
Phase: Phase 2/Phase 3
Study type: Interventional

Acoziborole as an oral, single-dose treatment was studied in an open-label pivotal Phase II/III trial (DNDi-OXA-02-HAT) in DRC and Guinea. The safety and efficacy results on g-HAT confirmed cases (all disease stages) from the pivotal study provided data, that allows to envision the treatment of confirmed g-HAT cases but there is still a gap in the management of g-HAT seropositive non-parasitologically confirmed individuals. Indeed, the standard g-HAT case definition implies the demonstration of the parasite in any body fluid via microscopy. However, there are factors such as low parasitaemia and the complexity and low sensitivity of parasitological methods that make such demonstration difficult. It has been demonstrated that a variable proportion (mainly depending on the prevalence) of such g-HAT "sero-suspects" are confirmed cases and, therefore, remaining as potential reservoirs of the parasite and a source of new infections hindering the efforts to eliminate the disease. The present clinical trial intends to expand the safety data of acoziborole and complement the safety profile obtained from the pivotal trial by assessing the safety and tolerability of a single dose of acoziborole compared with placebo in seropositive individuals who are not confirmed parasitologically. In addition to this study, an exploratory sub-study named 'TrypSkin' is planned to assess the presence of extravascular dermal T.b. gambiense in the population enrolled.
