  • Absolute lymphocyte count (ALC) <500 cells/ µL in allogeneic HCT recipients. Absolute lymphocyte count (ALC) <300 cells/ µL in autologous HCT recipients.
  • Laboratory confirmed RSV diagnosis from a respiratory sample obtained within 3 days before 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 imaging (chest x-ray and/or computed tomography) performed in the 2 days before signing the ICF or at the Screening visit if there is no chest X-ray and/or computed tomography available in the 2 days before signing the ICF.
  • Oxygen saturation >95% 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.
