Study type
Description of intervention(s) / exposure
There will be 5 groups each assigned to receive a different dose level of study drug or placebo. Choice of dose level(s) to be administered will be made based upon a review performed by the investigator and the sponsor representatives of the blinded safety, tolerability and pharmacokinetic data.

Arm 1 - Experimental: SAR441121 - a single dose starting at 5mg under fasting conditions (overnight fasting up to 4 hours post dose) according to an ascending dose design.
SAR441121 selected single dose in fed conditions. A standardized high fat breakfast of 800 kcal will be given to the participant 30 minutes prior to study drug intake.

Treatment: Drugs: SAR441121
Pharmaceutical form: Tablet
Route of administration: Oral
Duration: Single dose

The strategies used to monitor adherence to the study drug will be: administration under direct medical supervision, mouth inspection for checking the ingestion, appropriate record of the dosing information, counts of the number of tablets.

Comparator / control treatment
Arm 2 - Placebo Comparator - Matching placebo (microcellulose tablet) for SAR441121 single dose under fasting conditions.

Pharmaceutical form: Tablet
Route of administration: Oral
Duration: Single dose
Control group

Primary outcome [1] 307835 0
To assess the tolerability and safety of ascending single oral doses of SAR441121 through , Number of participants with Adverse Events (AEs) by participant reporting and physician observation.
This study is a first in human study and there are no examples of treatment emergent adverse event (TEAE) that can be provided at this stage of drug development. From preclinical data, only monitoring of liver enzymes is proposed.
Timepoint [1] 307835 0
From 27 day screening period up to Day 28 post study drug administration,
Assessments are once during the screening period, the day prior to and day of study drug administration, daily up to 6 days post study drug administration, then weekly up to 28 days post study drug administration, or as reported by participant.
Secondary outcome [1] 353083 0
To assess the pharmacokinetic (PK) parameters of ascending single oral doses of SAR441121.
PK parameters are Cmax, tmax, AUClast, AUC, as assessed in plasma assay.
Timepoint [1] 353083 0
Day of study drug administration to Day 28 post study drug administration.
Daily from Day 1 to Day 5, then at Day 8, Day 14, Day 21, Day 28

Brief summary
SAR441121 is an experimental treatment. This means that it is not an approved treatment for Malaria in Australia by the Regulatory Authority (Therapeutic Goods Administration - TGA) or any other international Regulatory Authority.
The purpose of this study is to establish the safety, tolerability (how easily it is to tolerate) and pharmacokinetics (what the body does to the study drug, such as absorption, distribution and excretion) of SAR441121 in healthy male volunteers, This study also aims to investigate the effect that food may have in the safety, tolerability and pharmacokinetics of the study drug.
