2. Received an autologous or allogeneic HCT using any conditioning
regimen

collected ≤ 6 days prior to Day 1 or as determined at Screening as per Section 6.1.1
4. New onset of at least 1 of the following respiratory symptoms for ≤ 7
days prior to Day 1: nasal congestion, runny nose, cough, or sore throat,

relative to the most recent chest X-ray, as determined by the local
radiologist. If a chest X-ray is not available or was not obtained during
standard care < 48 hours prior to Screening, a chest X-ray must be
obtained for Screening
6. O2 saturation ≥ 92% on room air
7. An informed consent document signed and dated by the subject or a
legal guardian of the subject and the investigator or his/her designee. In
Sweden ICFs signed by a legal guardian must also be signed by a close
relative of the subject
8. A negative urine or serum pregnancy test is required for female
subjects (unless surgically sterile or greater than two years postXML

menopausal)
9. Male and female subjects of childbearing potential must agree to
contraceptive requirements as described in Appendix 5
10. Willingness to complete necessary study procedures and have
available a working telephone or email |

E.4 | Principal exclusion criteria |
Related to concomitant or previous medication use:
1. Use of non-marketed (according to region) investigational agents
within 30 days, OR use of any investigational monoclonal anti-RSV
antibodies within 4 months or 5 half-lives of Screening, whichever is
longer, OR use of any investigational RSV vaccines after HCT.
2. Use of a moderate or strong cytochrome P450 enzyme (CYP) inducer
including but not limited to rifampin, St. John's Wort, carbamazepine,
phenytoin, efavirenz, bosentan, etravirine, modafinil, and nafcillin,
within 2 weeks prior to the first dose of IMP
Related to medical history:
3. Admitted to the hospital primarily for a lower respiratory tract disease
of any cause as determined by the investigator
4. Pregnant, breastfeeding, or lactating females
5. Unable to tolerate nasal sampling required for this study, as
determined by the investigator
6. Known history of HIV/AIDS with a CD4 count <200 cells/μL within the
last month
7. History of drug and/or alcohol abuse that, in the opinion of the
investigator, may prevent adherence to study activities
Related to medical condition at Screening:
8. Documented to be positive for other respiratory viruses (limited to
influenza, parainfluenza, human rhinovirus, adenovirus, human
metapneumovirus, or coronavirus) within 7 days prior to the Screening
visit, as determined by local testing (additional testing is not required)
9. Clinically significant bacteremia or fungemia within 7 days prior to
Screening that has not been adequately treated, as determined by the
investigator
10. Clinically significant bacterial, fungal, or viral pneumonia within 2
weeks prior to Screening that has not been adequately treated, as
determined by the investigator
11. Excessive nausea/vomiting at Screening, as determined by the
investigator, or an inability to swallow pills that precludes oral
administration of the IMP (for subjects without an NG tube in place)
12. Any condition which, in the opinion of the investigator, would
prevent full participation in this trial or would interfere with the
evaluation of the trial endpoints
Related to allergies:
13. Known hypersensitivity or allergy to the IMP, its metabolites, or
formulation excipients (microcrystalline cellulose, mannitol,
croscarmellose sodium, magnesium stearate, polyvinyl alcohol, titanium
dioxide, polyethylene glycol and talc)
14. History of hypersensitivity, anaphylactic reaction, Stevens-Johnson
Syndrome, or toxic epidermal necrolysis response to sulfa drugs
Related to laboratory results:
15. Creatinine clearance < 30 mL/min (calculated using the Cockcroft-
Gault method)
16. Clinically significant ALT/AST, as determined by the investigator
17. Clinically significant TB, as determined by the investigator |
