Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Participant has provided written consent
  • In the Investigator's opinion, the participant is able to understand and comply with protocol requirements, instructions, and protocol-stated restrictions and is likely to complete the study as planned
  • Participant is in good health as deemed by the Investigator, based on the findings of a medical evaluation including medical history, physical examination, laboratory tests, and electrocardiogram (ECG). In case of an out-of-range clinical laboratory test, vital sign, or ECG value that will determine a participant's eligibility, a retest can be done. Results of this retest must be available prior to the first administration of the study drugs (Parts 1, 3, 5, and 6) or prior to inoculation (Part 4). The result of the retest will be considered for participant eligibility
  • Body mass index (BMI) of 18 to 30 kilogram per meter square (kg/m^2) (inclusive), minimum weight of 50 kilogram (kg)
  • A female participant is eligible to participate in this study if she is of non childbearing potential defined as either (i) premenopausal with a documented tubal ligation, bilateral oophorectomy, or hysterectomy; or (ii) postmenopausal defined by 12 months of spontaneous amenorrhea and follicle-stimulating hormone level within the laboratory's reference range for postmenopausal females. A postmenopausal female who is receiving hormone replacement therapy and who is willing to discontinue hormone therapy from 28 days before study drug dosing (Parts 1, 3, 5, and 6) or before inoculation (Part 4), and for the entire duration of the study, may be eligible for study participation. A male participant is eligible to participate in this study if (i) he is either surgically sterile or, (ii) in case of having a female partner of childbearing potential, the male participant and partner are practicing and willing to continue to practice highly effective forms of birth control until 90 days after the end of the study. Irrespective of the partner's form of birth control, a male participant must wear a condom when engaging in any activity that allows for passage of ejaculate to another person

Exclusion criteria

  • Clinically significant cardiovascular, respiratory, renal, gastrointestinal, hematologic, neurologic, endocrinologic, oncologic, ophthalmologic, musculoskeletal, psychiatric or any other uncontrolled medical illness
  • Positive human immunodeficiency virus (HIV), active hepatitis A virus (HAV), hepatitis B virus (HBV), or hepatitis C virus (HCV) test
  • Creatinine clearance less than (<) 60 milliliter per minute (mL/min) (Cockcroft-Gault)
  • Drug allergy such as, but not limited to, allergy to penicillins, including allergies experienced in previous studies with experimental drugs
  • Any condition that, in the opinion of the Investigator, would compromise the study or the well-being of the participant or prevent the participant from meeting the study requirements

Treatment and study plan

JNJ-64417184

Drug

Participants will receive JNJ-64417184 in Parts 1, 2A, 2B, 3, 4, 5 and 6.

Placebo

Drug

Participants will receive matching placebo to JNJ-64417184 in Parts 1, 2A, 2B, 3, 4, 5 and 6.

Primary outcomes

  1. Number of Participants With Adverse Events (AEs) as a Measure of Safety and Tolerability

    Time frame: Approximately up to 8 months

    An AE is any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship.

  2. Number of Participants With Laboratory Abnormalities

    Time frame: Approximately up to 8 months

    Number of participants with laboratory abnormalities will be reported.

  3. Number of Participants With Clinically Significant Changes in Vital Signs

    Time frame: Approximately up to 8 months

    Number of participants with clinically significant changes in vital signs will be reported.

  4. Number of Participants With Clinically Significant Changes in Physical Examination Findings

    Time frame: Approximately up to 8 months

    Number of participants with clinically significant changes in physical examination findings will be reported.

  5. Number of Participants With ECG Abnormalities

    Time frame: Approximately up to 8 months

    Number of participants with electrocardiogram (ECG) abnormalities will be reported.

  6. Change From Baseline in QT Interval Corrected According to Fridericia's Formula (QTcF) (Parts 1 and 3)

    Time frame: Baseline up to Day 31

    The QT interval corrected for heart rate (QTc interval) using Fridericia method will be measured by electrocardiograms (ECG) triplicates.

  7. Change From Baseline in Forced Expiratory Volume in 1 Second (FEV1) Absolute as Measured by Spirometry (Part 4)

    Time frame: Baseline up to Day 31

    FEV1 is the amount of air that can be exhaled in one second. FEV1 will be measured by spirometry. A positive change from baseline in absolute FEV1 indicates improvement in lung function.

  8. Change From Baseline in Forced Vital Capacity (FVC) Absolute as Measured by Spirometry (Part 4)

    Time frame: Baseline up to Day 31

    FVC is a standard pulmonary function test used to quantify respiratory muscle weakness. FVC is the volume of air that can forcibly be blown out after full inspiration in the upright position, in liters and will be measured by spirometry.

  9. Change From Baseline in Percent-Predicted FEV1 (Part 4)

    Time frame: Baseline up to Day 31

    FEV1 is the amount of air, measured in liters, forcibly exhaled in 1 second. Pulmonary function tests will be performed by participants in the morning before dosing. The percent predicted FEV1 equals the participant's observed FEV1 divided by the participant's predicted FEV1 (determined by height and race) and converted to a percentage by multiplying by 100 percent (%).

  10. Change From Baseline in Percent-Predicted FVC (Part 4)

    Time frame: Baseline up to Day 31

    Predicted FVC is based on a formula using sex, age and height of a person, and is an estimate of healthy lung capacity. Percent of predicted FVC = (observed value)/(predicted value) * 100 %.

    Time frame: Up to Day 7

    The AUC(0-Dosing Day 7) of RSV viral load from treatment onset, as determined by a qRT-PCR assay of nasal wash samples and by cell culture (plaque assay) will be reported.

  5. Time to Non-Detectability of RSV (Part 4)

    Time frame: Up to Day 31

    Time to non-detectability of RSV as determined by a qRT-PCR assay of nasal wash samples and by cell culture (plaque assay) will be reported.

  6. Peak RSV Viral Load by Dosing Day (Part 4)

    Time frame: Up to Day 31

    Peak RSV viral load by dosing day as determined by a qRT-PCR assay of nasal wash samples and by cell culture (plaque assay) will be reported.

  7. AUC(0-Dosing Day 7) of Total RSV Symptoms From Treatment Onset

    Time frame: Up to Day 7

    The AUC(0-Dosing Day 7) of total RSV symptoms from treatment onset, using self reported symptoms on the symptom diary card (SDC) will be reported. Participants will assess any challenge virus-related symptoms using the symptom questionnaire in the SDC which will report the symptoms experienced by the participants at the moment on a scale of 0 to 3 where '0' implies 'no symptom' and '3' implies 'bothersome most or all of the time, stopping from participating in activities' OR 'less severe' to 'more severe' symptoms.

  8. Total Weight of Mucus (Part 4)

    Time frame: Up to Day 12

    The total weight of mucus produced from treatment onset will be reported.

  9. Change From Baseline in the RSV L Protein-Encoding Gene Sequence After Treatment (Part 4)

    Time frame: Baseline up to Day 11
