Inclusion Criteria:

  • Male or female, aged 2 months and older at the time of informed consent.
  • AdV DNA viremia >10,000 copies/mL from a single sample, or 2 samples greater than 48 hours apart with the second result higher than the first and both greater than 1000 copies/mL, from the data obtained from the designated central virology laboratory of the local laboratory using the blood sample(s) collected informed consent has been obtained and within 7 days prior to Day 1 (AdV DNA viremia results collected within the 7 day window, but prior to consent may be used if the Informed Consent Form (ICF) signed by the subject provides approval) .
  • Either (a) have disseminated AdV disease or (b) have an underlying immunocompromised state, and have asymptomatic AdV infection or localized AdV disease.
  • In the judgment of the investigator, be in a serious condition to be treated with intravenous cidofovir for AdV.

Exclusion Criteria:

  • Subjects who weigh ≥120 kg.
  • NIH/NCI CTCAE (United States [US] National Institutes of Health [NIH]/National Cancer Institute) Grade 2 or higher diarrhea (i.e., increase of ≥ 4 stools per day over usual pre-transplant stool output) within 7 days prior to Day 1.
  • NIH Stage 4 acute GVHD of the skin (i.e., generalized erythroderma with bullous formation) within 7 days prior to Day 1.
  • NIH Stage 2 or higher acute GVHD of the liver function (i.e., bilirubin >3 mg/dL [SI: >51 μmol/L]) within 7 days prior to Day 1.
  • NIH Stage 2 or higher acute GVHD of the gut (i.e., diarrhea >556 mL/m2/day for pediatric subjects [or >1000 mL/day for young adults as applicable, at centers in the United States only], or severe abdominal pain with or without ileus) within 7 days prior to Day 1.
