A Study of Maribavir Pediatric Formulation in Healthy Adult Participants

Completed · Phase 1

Conditions studied: Healthy Volunteers

In brief

The study will have 2 parts, Part 1 and Part 2. Participants will only participate in one part. The main aim of Part 1 of this study is to check the ability of a single dose of maribavir pediatric formulation to be absorbed in the digestive tract compared to commercial tablet formulation and to check how a high-fat, high-calorie meal affects absorption, distribution, and elimination of maribavir pediatric formulation given orally as water suspension. The main aim of Part 2 of this study is to assess the stomach acid reducing effect of multiple doses of rabeprazole on absorption, distribution, and elimination of maribavir pediatric formulation given orally as water suspension. Each participant will stay in the study clinic from the day before the first treatment until the day after the last treatment.

• Healthy as determined by the Investigator or designee on the basis of screening evaluations and medical history.
• Hemoglobin for males greater than or equal to (>=) 135.0 gram per liter (g/L) and females >=120.0 g/L, at the screening visit and on Day -1 of Treatment Period 1.
• Ability to swallow a dose of maribavir or rabeprazole.

You may not qualify if…

• History or presence of gastritis, gastrointestinal (GI) tract disorder, hepatic disorder or cholecystectomy, history of treated or untreated Helicobacter pylori, ulcer disease or other clinical condition which, in the opinion of the investigator or designee, may affect the absorption, distribution, metabolism, or elimination of the study drugs.
• History of any hematological, hepatic, respiratory, cardiovascular, renal, neurological or psychiatric disease, gall bladder removal, or current recurrent disease that could affect the action, absorption, or disposition of the study drugs, or clinical or laboratory assessments.
• Current or relevant history of physical or psychiatric illness, any medical disorder that may require treatment or make the participant unlikely to fully complete the study, or any condition that presents undue risk from the study drugs or procedures.
• Known or suspected intolerance or hypersensitivity to maribavir or rabeprazole (Part 2 only), closely related compounds, or any of the stated ingredients and excipients.
• Significant illness, as judged by the Investigator or designee, within 2 weeks of the first dose of the investigational drug (ID).
• Has diarrhea within 4 hours of the first dose of the ID.
• Donation of blood or blood products (example, plasma or platelets) within 60 days prior to receiving the first dose of the ID.
• Within 30 days prior to the first dose of the ID:
• Have used any investigational product (if elimination half-life is less than [<] 6 days, otherwise 5 half-lives).

• Corrected QT interval (QTc) >450 millisecond (msec) at the screening visit. If QTc exceeds 450 msec, the ECG should be repeated two more times and the average of the three QTc values should be used to determine the participant's eligibility.
• Known history of alcohol or other substance abuse within the last year.
• Male participants who consume more than 21 units of alcohol per week or three units per day. Female participants who consume more than 14 units of alcohol per week or two units per day (one alcohol unit = one beer or one wine [5 ounces [oz]/150 milliliter [mL]] or one liquor [1.5 oz/40 mL] or 0.75 oz alcohol).
