Key inclusion & exclusion criteria
|
Inclusion criteria: 1. Males and females 18 to 75 years of age
2. Received an autologous or allogeneic HCT using any conditioning regimen
3. Documented to be RSV-positive as determined by local testing (eg, PCR, DFA, RVP assay, or culture) using an upper respiratory tract sample collected = 6 days prior to Day 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, or worsening of one of these chronic (associated with a previously existing diagnosis, eg, chronic rhinorrhea, seasonal allergies, chronic lung disease), respiratory symptoms = 7 days prior to Day 1
5. No evidence of new abnormalities consistent with LRTI on a chest X-ray 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
8. A negative urine or serum pregnancy test is required for female subjects (unless surgically sterile or greater than two years post-menopausal)
9. Male and female subjects of childbearing potential who engage in heterosexual intercourse must agree to use protocol specified method(s) of contraception as described in Appendix 5
10. Willingness to complete necessary study procedures and have available a working telephone or email Are the trial subjects under 18? no Number of subjects for this age range: F.1.2 Adults (18-64 years) yes F.1.2.1 Number of subjects for this age range 50 F.1.3 Elderly (>=65 years) yes F.1.3.1 Number of subjects for this age range 150
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 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, and phenytoin, efavirenz, bosentan, etravirine, modafinil, and nafcillin, within 1 week 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, or 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 AST/ALT, as determined by the investigator
17. Clinically significant TB, as determined by the investigator

Primary Outcome(s)
|
Secondary Objective: - To evaluate the effect of GS-5806 on development of LRTC, progression to respiratory faliure, and all-cause mortality - To evaluate the PK, safety, and tolerability of GS-5806
|
Main Objective: To evaluate the effect of GS-5806 on RSV viral load in RSV-positive autologous or allogeneic HCT recipients with acute URTI symptoms
|
Primary end point(s): Time-weighted average change in nasal RSV viral load (log10 copies/mL) from Baseline (Day 1) to Day 9 as measured by RT-qPCR

|
Secondary Outcome(s)
|
Timepoint(s) of evaluation of this end point: Day 28.
|
Secondary end point(s): Proportion of subjects who develop a LRTC through Day 28, defined as one of the below, as
determined by the adjudication committee:
