The purpose of this study is to learn how different preparations of sisunatovir are taken up into the blood when taken on an empty stomach or with a meal in healthy adults.
This study has two Parts and is seeking participants who:
- are healthy males or females of 18 years of age or older.
Part 1:
All participants will receive treatments: A, B, and C. The participants will be assigned to take medicines A, B or C by chance, like drawing names out of a hat.
All treatments will be taken by mouth.
Part 2:
All participants will receive treatments: B and D. The participants will be assigned to take medicines B and D by chance, like drawing names out of a hat.
All treatments will be taken by mouth.
The participants will be in the study clinic for 10 days in Part 1 and 7 days in Part 2, for:
All participants selected in the study will be required to go through a screening period up to 28 days. A screening period is the time during which a few participants are tested to see whether they are fit for the study. The participants can join the study only if they are tested be fit and are interested to take part in the study.
The participants will be allowed to go home on Day 10 during Part 1, and on Day 7 during Part 2. About 28 to 35 days after being sent home following the final treatment, the participant will be contacted for a follow up visit either in person or by telephone. This is to check up on how the participant is doing and to end the study.

Inclusion Criteria:
Participants aged 18 years of age or older, inclusive, at the time of signing of the informed consent document (ICD).
• All fertile participants must agree to use a highly effective method of contraception.
Male and female participants who are overtly healthy as determined by medical evaluation including medical history, physical examination, laboratory tests, and cardiac evaluation.
Body mass index (BMI) of 18 to 32 kg/m2; and a total body weight >45 kg (100 lb).
Exclusion Criteria:
Evidence or history of clinically significant hematological, renal, endocrine, pulmonary, gastrointestinal, cardiovascular, hepatic, psychiatric, neurological, or allergic disease (including drug allergies, but excluding untreated, asymptomatic, seasonal allergies at the time of dosing).
Any medical or psychiatric condition including recent (within the past year) or active suicidal ideation/behavior or laboratory abnormality or other conditions that may increase the risk of study participation or, in the investigator's judgment, make the participant inappropriate for the study.
Use of prescription or nonprescription drugs and dietary and herbal supplements within 7 days or 5 half-lives (whichever is longer) prior to the first dose of study intervention, with the exception of moderate/strong CYP3A inducers or time-dependent inhibitors which are prohibited within 14 days plus 5 half-lives prior to the first dose of study intervention
Previous administration with an investigational product (drug or vaccine) within 30 days (or as determined by the local requirement) or 5 half-lives preceding the first dose of study intervention used in this study (whichever is longer).
A positive urine drug test, confirmed by a repeated test, if deemed necessary.
For participants <60 years: Screening supine BP ≥140 mm Hg (systolic) or
Standard 12-lead ECG that demonstrates clinically relevant abnormalities that may affect participant safety or interpretation of study results (eg, QTcF >450 ms, complete LBBB, signs of an acute or indeterminate- age myocardial infarction, ST-T interval changes suggestive of myocardial ischemia, second- or third- degree AV block, or serious bradyarrhythmias or tachyarrhythmias). If the uncorrected QT interval is >450 ms, this interval should be rate-corrected using the Fridericia method only and the resulting QTcF should be used for decision making and reporting. If QTcF exceeds 450 ms, or QRS exceeds 120 ms, the ECG should be repeated twice and the average of the 3 QTcF or QRS values used to determine the participant's eligibility. Computer-interpreted ECGs should be overread by a physician experienced in reading ECGs before excluding a participant.
Participants with ANY of the following abnormalities in clinical laboratory tests at screening, as assessed by the study-specific laboratory and confirmed by a single repeat test, if deemed necessary:
History of alcohol abuse or binge drinking and/or any other illicit drug use or dependence within 6 months of Screening. Binge drinking is defined as a pattern of 5 (male) and 4 (female) or more alcoholic drinks in about 2 hours. As a general rule, alcohol intake should not exceed 14 units per week (1 unit = 8 ounces (240 mL) beer, 1 ounce (30 mL) of 40% spirit, or 3 ounces (90 mL) of wine).
History of sensitivity to sisunatovir or any of the formulation components.
Use of tobacco or nicotine-containing products in excess of the equivalent of 5 cigarettes/day or 2 chews of tobacco/day
Investigator site staff directly involved in the conduct of the study and their family members, site staff otherwise supervised by the investigator, and sponsor and sponsor delegate employees directly involved in the conduct of the study and their family members

| Secondary | AUCinf of Sisunatovir WGT Under Fasted vs With a Low-fat Meal, Part 2 | AUCinf was calculated as AUClast + (Clast*/kel), where Clast is the predicted plasma concentration at the last quantifiable time point from the log-linear regression analysis, and kel is the terminal phase rate constant calculated by a linear regression of the loglinear concentration-time curve. Treatment B = sisunatovir 200 mg WGT under fasted condition; reference treatment. Treatment D= sisunatovir 200 mg WGT with low-fat meal; test treatment. | PK parameter analysis set included all randomized participants who received at least one dose of study medication and in whom at least 1 plasma PK parameter was calculated. Here "Overall Number of Participants Analyzed" signifies participants evaluable for this outcome measure. | Posted | Geometric Mean | Geometric Coefficient of Variation | nanogram* hour per milliliter (ng*hr/mL) | Pre-dose (0 hour), 1, 2, 3, 4, 5, 6, 8, 10,12 hours post-dose on Day 1; 24, 36 hours post-dose on Day 2; 48 hours post-dose on Day 3 of Period 1-3; 72 hours post-dose on Day 4 of period 3 |

| Secondary | Number of Participants With Treatment Emergent Adverse Events (TEAEs): Part 1 | An adverse event (AE) was any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. TEAEs were any AEs that occurred following start of treatment up to 35 days post last dose. Treatment A= sisunatovir 200 mg PIC under fasted condition; treatment B = sisunatovir 200 mg WGT under fasted condition and treatment C= sisunatovir 200 mg WGT with a high-fat meal. | Safety analysis set included all participants randomly assigned to study intervention and who took at least 1 dose of study intervention. | Posted | Count of Participants | Participants | From start of study treatment on Day 1 up to 35 days after last dose of study drug (maximum up to 43 days) |

| Secondary | Number of Participants With Clinically Significant 12-lead Electrocardiogram (ECG) Findings: Part 1 | A standard 12-lead ECGs utilizing limb leads were collected using an ECG machine that automatically calculated the heart rate (HR) and measures pulse rate (PR), QT, and QTc corrected using Fridericia's formula (QTcF) intervals and QRS complex with the participant in a supine position after at least 5 minutes of rest. Following ECG parameters were analyzed: post-dose QTcF interval is increased by ≥60 ms from the baseline and is >450 ms; or an absolute QT value is ≥500 ms for any scheduled ECG. Clinically significant ECG abnormality findings were based on investigator discretion. Treatment A= sisunatovir 200 mg PIC under fasted condition; treatment B = sisunatovir 200 mg WGT under fasted condition and treatment C= sisunatovir 200 mg WGT with a high-fat meal. | Safety analysis set included all participants randomly assigned to study intervention and who took at least 1 dose of study intervention. | Posted | Count of Participants | Participants | From start of study treatment on Day 1 up to 35 days after last dose of study drug (maximum up to 43 days) |
