1. An ICF signed and dated by the subject
2. Male or female individuals aged between 16 and 75 years, inclusive
3. Received an autologous HCT (within 6 months of signing ICF) or an allogeneic HCT (any time) using any conditioning regimen
4. Absolute lymphocyte count (ALC) <500 cells/ µL in allogeneic HCT recipients. Absolute lymphocyte count (ALC) <300 cells/ µL in autologous HCT recipients.
5. Laboratory confirmed RSV diagnosis from a respiratory sample within 3 days before signing the ICF. The RSV diagnosis can be determined by any validated laboratory method.
6. New onset of at least one of the following respiratory symptoms within 3 days before signing the ICF: nasopharyngeal discharge, nasopharyngeal congestion, sneezing, sinus congestion, sore throat, hoarseness, earache, cough, shortness of breath, respiratory wheeze, or worsening of one of these symptoms if present chronically (associated with a previously existing diagnosis [eg, chronic rhinorrhea, chronic lung disease]) in the 3 days before signing the ICF or at Screening.
7. No evidence of new abnormalities consistent with LRTI on chest imaging (chest x-ray and/or computed tomography) performed in the 2 days before signing the ICF. If there is no chest imaging available in the 2 days before signing the ICF, a chest imaging (chest x-ray and/or computed tomography) must be obtained at the Screening visit.
8. Oxygen saturation =95% on room air.
9. A body mass index (BMI) =18 kg/m2 and =40 kg/m2 and a body weight of =50 kg.
10. Negative urine pregnancy test for women of childbearing potential as defined in inclusion criterion #11.
11. A woman of childbearing potential who is sexually active with a male must agree to use two effective methods of contraception from the date of Screening until 30 days after her last dose of study drug. Effective methods of contraception are defined as follows:
A condom for the male partner and at least one of the following for the female subject:
a. Intrauterine device
b. Oral, injectable, implantable, transdermal, or intravaginal hormonal contraceptive
(Note: hormonal contraception must be associated with the inhibition of ovulation)
The above does not apply to 1) a female subject who has a vasectomized male partner provided that partner is the sole sexual partner of the subject and the vasectomized partner has received medical assessment of surgical success or 2) a female subject who is of nonchildbearing potential (ie, physiologically incapable of becoming pregnant) as defined below:
a. Has had a complete hysterectomy =3 months before Screening,
b. Has had a bilateral oophorectomy (ovariectomy),
c. Has had a bilateral tubal ligation or fallopian tube inserts, or
d. Is postmenopausal (a total cessation of menses for at least 2 years; subjects with a cessation of menses between 1 to 2 years and a follicle-stimulating hormone [FSH] level of >35 mIU/mL will also be considered to be postmenopausal.)
12. A male subject who has not had a vasectomy and is sexually active with a woman of childbearing potential must agree to use effective contraception from the date of Screening to 90 days after his last dose of study drug. Effective contraception is defined as a condom and at least one of the following for a female partner:
a. Intrauterine device
b. Oral, injectable, implantable, transdermal, or intravaginal contraceptive
(Note: hormonal contraception must be associated with the inhibition of ovulation).
13. Male subjects must agree to refrain from sperm
1. Admitted to the hospital primarily for a lower respiratory tract disease of any cause as determined by the Investigator.
2. Known to be concurrently infected with other respiratory viruses (eg, severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2] or other coronavirus, influenza, parainfluenza, human rhinovirus, adenovirus, human metapneumovirus) within 7 days before signing the ICF, as determined by local testing.
3. Clinically significant viremia, bacteremia, or fungemia, or bacterial or fungal pneumonia within 2 weeks before signing the ICF that has not been adequately treated, as determined by the Investigator.
4. Pregnant or nursing female subjects.
5. History of drug and/or alcohol abuse that, in the opinion of the Investigator, may prevent adherence to protocol activities.
6. Known positive human immunodeficiency virus (HIV).
7. Heart disease: any congenital heart disease, congenital long QT syndrome, or any clinical manifestation resulting in QT interval prolongation. Chronic heart failure or ischemic heart disease or cardiac disease occurring as a consequence of antineoplastic treatment and for which treatment medications have not added or increased in the last 3 months are not exclusionary.
8. Known malignant tumor that may interfere with the aims of the study or a subject completing the study.
9. Prior or planned ileal resection or bariatric surgery. Subjects who have undergone gastric surgeries that do not affect drug absorption (eg, gastric band or gastric sleeve procedures) will be allowed to participate if they are stable for at least 1 year before signing the ICF. Gastrectomy will be allowed if stable for at least 3 years before signing the ICF.
10. Estimated glomerular filtration rate by Modification of Diet in Renal Disease (MDRD) <50 mL/min as measured in the 3 days before signing the ICF or at Screening.
11. Alanine aminotransferase >5 × ULN as measured in the 3 days before signing the ICF or at Screening.
12. Twelve-lead ECG demonstrating a QT interval corrected for heart rate according to Fridericia (QTcF) that is > 470 milliseconds or other clinically relevant abnormalities as judged by the Investigator at Screening.
13. Use of or intention to use any medication or supplement known to be a moderate or strong inducer or inhibitor of the CYP3A4 enzyme (Section 5.8) within 14 days before signing the ICF, with the exception of prophylactic azole antifungal therapies (e.g., fluconazole, itraconazole, ketoconazole, isavuconazole, posaconazole, and voriconazole), which are permitted with EDP-938 dose adjustment (Section 4.2.2)
14. Use of nonmarketed (according to region) or investigational agents, vaccines, biological products within 30 days or five half-lives before signing the ICF, whichever is longer.
15. Use of any investigational monoclonal anti-RSV antibodies within 4 months or five half-lives of signing the ICF, whichever is longer, or use of any investigational RSV vaccines after HCT.
16. Known hypersensitivity or allergy to EDP-938 or placebo or their excipients.
17. History of or currently experiencing a medical condition or any other finding (including laboratory test results) that, in the opinion of the Investigator, might confound the results of the study, pose an additional risk in administering study drug to the subject, could prevent, limit, or confound the protocol-specified assessments, or deems the subject unsuitable for the study.
