Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine the safety and tolerability of intravenous (IV) brincidofovir (BCV; SyB V-1901) 0.2 mg/kg, 0.3 mg/kg or 0.4 mg/kg dosed twice weekly (BIW) or 0.4 mg/kg dosed once weekly (QW) for 4 weeks in subjects with AdV, and IV BCV in subjects with CMV

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This is a Phase IIa, open-label, multiple ascending dose confirmation, multicenter study to evaluate the safety and tolerability of intravenous Brincidofovir (BCV, SyB V-1901) 0.2 mg/kg, 0.3 mg/kg, or 0.4 mg/kg dosed BIW or 0.4 mg/kg dosed QW (Cohorts 1 to 4) in adult and pediatric subjects with AdV viremia, and IV BCV in subjects with CMV.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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) . CMV viremia with or without evidence of tissue invasive CMV disease. For laboratory results that are generated in units other than copies/mL or IU/mL, please refer to the testing laboratory for guidance on the appropriate conversion calculation.
* 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.
