DRUGAticaprant Therapeutic Dose

Aticaprant therapeutic dose capsule will be administered orally.

DRUGPlacebo

Placebo will be administered orally.

DRUGMoxifloxacin

Moxifloxacin capsule will be administered orally.

Inclusion criteria

* Healthy on the basis of physical examination, medical history, vital signs, and 12-lead electrocardiogram (ECG) performed at screening and admission to the study center on Day -1 of the first treatment period. Minor abnormalities in ECG, which are not considered to be of clinical significance by the investigator, are acceptable * Body mass index (BMI; weight \[kilograms {kg}/ height square \[meter square {m\^2}\]) between 18 and 30.0 kg/m\^2 (inclusive), and body weight not less than 50 kg at screening * All female participants must have a negative serum pregnancy test (Beta-human chorionic gonadotropin \[Beta-hCG\]) at screening and a negative urine pregnancy test at admission to the study site on Day -1 of the first treatment period * A woman must agree not to donate eggs (ova, oocytes) or freeze for future use for the purposes of assisted reproduction during the study and for a period of at least 90 days after receiving the last dose of study intervention * Non-smoker (not smoked for 3 months prior to screening)

Exclusion criteria

* History of or current significant medical illness including (but not limited to) cardiac arrhythmias or other cardiac disease, hematologic disease, lipid abnormalities, bronchospastic respiratory disease, diabetes mellitus, hepatic or renal insufficiency, thyroid disease, Parkinson's disease, infection, or any other illness that the investigator considers should exclude the participant * History of additional risk factors for Torsade de Pointes or the presence of a family history of short QT syndrome, long QT syndrome, sudden unexplained death at a young age (less than/equal to 40 years), drowning or sudden infant death syndrome in a first degree relative (that is, biological parent, sibling, or child) * Any skin condition likely to interfere with electrocardiographic electrode placement or adhesion * Breast implant or a history of thoracic surgery likely to cause abnormality of the electrical conduction through thoracic tissues * History of malignancy within 5 years before screening (exceptions are squamous and basal cell carcinomas of the skin and carcinoma in situ of the cervix, or malignancy, which is considered cured with minimal risk of recurrence)

Design outcomes

Primary

MeasureTime frameDescription
Change from Baseline in QTc at Each Time PointBaseline up to Day 4Change from baseline in QTc at each time point will be reported.

Secondary

MeasureTime frameDescription
Time To Reach The Maximum Observed Concentration of Aticaprant (Tmax)Predose up to 72 hours postdose (up to Day 4)Tmax is the actual sampling time to reach the maximum observed plasma concentration of aticaprant.
Area Under the Plasma Concentration-Time Curve From Time Zero to last of Aticaprant (AUC [0-last])Predose up to 72 hours postdose (up to Day 4)AUC (0-last) is the area under the plasma concentration-time curve from time 0 to the time of the last measurable (non-below quantification limit) concentration of aticaprant.
Area Under the Plasma Concentration-Time Curve From Time Zero to Infinite Time of Aticaprant (AUC[0-infinity])Predose up to 72 hours postdose (up to Day 4)AUC (0-infinity) is the area under the plasma concentration-time curve from time zero to infinite time of aticaprant.
Maximum Observed Concentration (Cmax) of AticaprantPredose up to 72 hours postdose (up to Day 4)Cmax is defined as the maximum observed plasma concentration of aticaprant and it's metabolite.
Number of Participants with AEs of Special Interest (AESI)Up to Day 4Number of participants with AESIs will be reported. Pruritus and severe diarrhea is considered to be an AESI.
Number of Participants With Change in Vital SignsUp to Day 4Number of participants with change in vital signs will be reported. Body temperature, blood pressure, and pulse/heart rate (HR) measurements will be assessed.
Number of Participants With Change in Laboratory ValuesUp to Day 4Number of participants with change in laboratory parameters will be reported. Hematology, serum chemistry, and routine urinalysis will be assessed.
Number of Participants With Adverse Events (AEs)Up to Day 4Number of participants with AEs will be reported. An AE is any untoward medical occurrence in a clinical study participant administered a pharmaceutical (investigational or non investigational) product.
