A Phase 1 interventional study of Fexinidazole/Placebo in Human African Trypanosomiasis, sponsored by Drugs for Neglected Diseases. Completed at 1 site in France. Open to male participants aged 18 Years to 45 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2017-04-06.
Sponsored by Drugs for Neglected Diseases · Phase 1, Interventional, and Treatment
This study is aimed at assessing the tolerability and pharmacokinetic parameters of the fexinidazole in healthy volunteers. In animal models of both acute and chronic experimental Trypanosomiasis infections, fexinidazole shows highly promising efficacy.
The present study is designed to obtain safety, tolerability and PK data after single and multiple oral administration of increasing doses of fexinidazole in healthy male sub-Saharan African subjects. This study will also assess the relative bioavailability of fexinidazole administered as a tablet in comparison with oral suspension, and to assess the impact of concomitant food intake on the relative bioavailability of fexinidazole after single oral dose administration.
The study will be divided in 3 successive parts. Study Part I will be a randomized, double-blind, placebo-controlled, single ascending dose study with fexinidazole administered as an oral suspension.
Study Part II will be a comparative bioavailability study of a fexinidazole tablet vs. the oral suspension and assessment of food effect, according to a three-way cross-over design. Clinical part will be conducted in open conditions and bioanalysis in blind conditions.
Study Part III will be a randomized, double-blind, placebo-controlled, multiple ascending dose study with fexinidazole administered either as an oral suspension or as a tablet, depending on Part II results. Dosage regimen will be either q.d. or b.i.d., depending on Part I and Part II results for the unchanged drug and the metabolites. Treatment duration will be 14 days.
Bioanalysis will be performed in open conditions for Study Part I and Study Part III.

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.
What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

A drug or device being studied in a clinical trial.
It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.
