Human African Trypanosomiasis: First in Man Clinical Trial of a New Medicinal Product, the SCYX-7158
Study Details
Study Description
Brief Summary
This study is aimed at assessing the tolerability and pharmacokinetic parameters of SCYX-7158 in healthy volunteers. In animal models of both acute and chronic experimental Trypanosomiasis infections, SCYX-7158 shows highly promising efficacy.

Phase 1 |
Detailed Description
The present study is designed to obtain safety, tolerability and PK data after single oral administration of increasing doses of SCYX-7158 in healthy male sub-Saharan African subjects. This study will also assess the impact on the relative bioavailability of SCYX-7158 administered as a capsule after single oral dose administration.
The study will be divided in 3 different parts. Study Part I will be a randomized, double-blind, placebo-controlled, single ascending dose study with SCYX-7158 administered as a capsule.
A other part is scheduled to evaluate the impact of activated charcoal intake on the PK characteristics of SCYX-7158 and determine the most adapted treatment schedule for charcoal to enhance SCYX-7158 elimination while allowing a sustained drug exposure likely to be therapeutically active.
A last part is planned to evaluate the pharmacokinetics of a new formulation (tablet) of SCYX-7158 in healthy male volunteers

Outcome Measures
Primary Outcome Measures
- Occurence of adverse events (AEs) [9 to 37 days, depending on the part of the study]
Monitoring for the occurrence of AEs. Changes in physical examination, vital signs (blood pressure and pulse rate), ECG, and clinical laboratory tests (biochemistry, hematology, and urinalysis).
Secondary Outcome Measures
- Pharmacokinetic (blood concentration of SCYX-7158 and metabolite) [from pre-dose until 168 h post-dose.]
- Pharmacokinetic (urine concentration of SCYX-7158 and metabolite) [from pre-dose until 168 h post-dose.]
Eligibility Criteria
Criteria
Inclusion Criteria:
-
Male healthy volunteers 18 to 45 years of age,
-
All subjects to be of sub-Saharan African origins with both parents of Sub-Saharan African origins too,
-
Male subjects with a body mass index (BMI) calculated as weight in kg/(height in m2) from 18 to 28 kg/m2 at screening,

Able to communicate well with the Investigator and research staff and to comply with the requirements of the entire study,
-
Provision of written informed consent to participate as shown by a signature on the volunteer consent form,
-
Light smokers (less than 5 cigarettes per day) or subjects who are non-smokers. No smoking (or use of smoking substitute e.g. nicotine patch) is permitted from screening throughout the study,
-
Normal arterial blood pressure (BP) and pulse rate or, if abnormal, considered not clinically significant by the principal Investigator. These will be measured after resting for 5 min.
-
Registered with the French Social Security in agreement with the French law on biomedical experimentation.
Exclusion Criteria:
-
Who on direct questioning and physical examination have evidence of any clinically significant acute or chronic disease, including known or suspected HIV, HBV or HCV infection,
-
Who previously received SCYX-7158,
-
Who presented acute or chronic or history of symptoms of Gastro intestinal disturbances (GI) or on physical examination have evidence of any clinical signs of acute or chronic GI abnormality ( i.e hemorrhoids, GI bleeding…)
-
With any clinically significant abnormality following review of pre-study laboratory tests (aspartate aminotransferase (ASAT) and alanine aminotransferase (ALAT) must be within normal ranges), vital signs, full physical examination and ECG,
-
Who are within the exclusion period defined in the National Register for Healthy Volunteers of the French Ministry of Health,
-
Who forfeit their freedom by administrative or legal award or who were under guardianship,
-
Unwilling to give their informed consent,
-
Who have a positive laboratory test for Hepatitis B surface antigen (HbsAg), or anti-HIV 1/2 or anti- HCV antibodies
-
Who have a history of allergy, intolerance or photosensitivity to any drug,
-
Who have a history of serious allergy, asthma, allergic skin rash or sensitivity to any drug,
-
Who are known or suspected alcohol or drug abusers (more than 14 units of alcohol per week, one unit = 8 g or about 10 mL of pure alcohol),
-
Who drink more than 8 cups daily of beverage containing caffeine,
-
Who have a positive laboratory test for urine drug screening (opiates, cocaine, amphetamine, cannabis, benzodiazepines),
-
Who have undergone surgery or have donated blood within 12 weeks prior to the start of the study,
-
Who have taken any prescribed or over the counter drug (including antacid drug), with the exception of paracetamol (up to 3 g per day) within 2 weeks prior to the first dose administration,
-
Who have any clinical condition or prior therapy which, in the opinion of the Investigator, made the subject unsuitable for the study,
-
Who participated to any clinical trial with an investigational drug in the past 3 months preceding study entry.
