Criteria

Inclusion Criteria:

• Received an autologous or allogeneic HCT using any conditioning regimen

• Absolute lymphocyte count (ALC) <500 cells/ µL

• Laboratory confirmed RSV diagnosis from a respiratory sample obtained not more than 3 days prior signing the ICF.

• 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.

• No evidence of new abnormalities consistent with LRTI on a chest X-ray performed in the 2 days before signing the ICF or at the Screening visit if there is no chest X-ray available in the 2 days before signing the ICF.

• Oxygen saturation >92% on room air.

• 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.

• 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.

Exclusion Criteria:

• Admitted to the hospital primarily for a lower respiratory tract disease of any cause as determined by the Investigator.

• 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.

• 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.

• Known positive human immunodeficiency virus (HIV).

• Any clinical manifestation resulting in QT prolongation.
