Background and study aims
DNDi is developing a new medicine to treat leishmaniasis which is a tropical disease with a strong link to poverty. Leishmaniasis is spread by the bite of certain types of sand-flies. Cases have been recorded in 101 countries around the world and there are 350 million people at risk of getting the disease. Symptoms of the disease can range from skin ulcers, fever, and weight loss and can be fatal if left untreated.
Treatments that are currently available for Leishmaniasis are limited, can be toxic and require a stay in hospital lasting several weeks. They are also not easy to administer. For example, some treatments need to be given by an infusion into the vein, others require several injections per day in the muscles. DNDi is conducting this study to develop a safer, short-term treatment that can be given easily by mouth without the requirement for long stays in hospital.
We will be looking at how the test medicine is taken up and broken down by the body. We will also look at the safety and tolerability of the test medicine and we may look at how food affects the way the test medicine is taken up and broken down by the body.

Who can participate?
To participate, you must have between 18 and 55 years of age for males, between 18 and 60 years of age for females, be a healthy male or be a healthy female who is no longer able to have children (considered as non-childbearing potential);

What does the study involve?
In this study, participants will either be given DNDI-0690 in the form of an oral capsule (one or multiple capsules per dose) or a placebo (which contains no active drug). Blood and urine samples will be taken at set time points throughout the study in order to measure the concentration profile of DNDI-0690 in the blood and urine, and how this changes over time. The researchers will compare the results from each of the groups to determine if there are any significant differences in the safety profile of DNDI-0690, the concentration of DNDI-0690 in the blood and urine. The purpose of the data generated in this study is to provide further information and guidance to support the study sponsor in the development of the study drug.

What are the possible benefits and risks of participating?
Taking part in this study is not expected to provide with any direct medical benefit. However, the information from this study may help improve the treatment of leishmaniasis. Risks associated with the trial participation are mainly drug side effects and inconveniences linked to study procedures. They are all described in the study Participant Information Sheet which can be consulted on this website.

Primary study designInterventional
Secondary study designRandomised parallel trial
Study setting(s)Pharmaceutical testing facility
Study typeTreatment
Participant information sheet 43355 PIS_V5.0 23Oct2019.pdf
Scientific titleA phase I, double-blind, randomised, single centre, parallel group, single-dose, dose-escalation, placebo-controlled study of the safety, tolerability and pharmacokinetics of DNDI-0690 after oral dosing in healthy subjects
Study acronymDNDi-0690-01
Study objectivesDNDI-0690 is safe to be dosed as a single dose in humans and provides sufficient exposure in healthy volunteers to be further investigated to treat visceral and cutaneous leishmaniasis.
Ethics approval(s)Approved 12/03/2019, London - Surrey Borders Research Ethics Committee (Health Research Authority, Skipton House, 80 London Road, London, SE1 6LH, UK; +44 207 104 8199; surreyborders.rec@hra.nhs.uk); ref: 19/LO/0373
Health condition(s) or problem(s) studiedVisceral leishmaniasis, cutaneous leishmaniasis
InterventionThis is a single centre, double-blind, randomised, placebo-controlled, parallel-group, single oral dose, dose-escalation study in healthy male and women of non-childbearing potential (WONCBP) subjects. It is planned to enroll 8 subjects in 8 planned cohorts. Cohorts 1 to 7 will include male subjects. Cohort 8 will include WONCBP subjects.

Subjects will be randomly assigned using an online tool to receive a single oral dose of active investigational medicinal products (IMP - DNDI-0690) or a matching placebo in a sequential escalating manner with a minimum of 7 days between dosing of each cohort.

The planned starting dose for Cohort 1 (Regimen A) will be 10 mg of DNDI-0690. Doses to be administered in Cohorts 2 to 8 will be determined based on emerging PK and safety data.
