A Multicenter Study to Obtain Retrospective Data for Subjects Previously Diagnosed With Adenovirus Infection to Serve as Matched Historical Controls for Study CMX001-304

A Multicenter Non-Interventional Study to Obtain Retrospective Data for Subjects Previously Diagnosed With Adenovirus Infection to Serve as Matched Historical Controls for Study CMX001-304

The objective is data collection to determine background rates of adenovirus (AdV) progression and mortality in subjects with Adenovirus (AdV) infection and/or disease.

The objective of this retrospective data collection is to determine background rates of adenovirus (AdV) progression and mortality in subjects with Adenovirus (AdV) infection and/or disease.

Inclusion Criteria:

• Matched-control cases must be recruited from sites participating in the CMX001-304 study and meet all of the following criteria, as applicable, to be eligible for data abstraction in this non-interventional retrospective study:
• Age at time of transplant: ≥ 2 months
• Eligible matched-control subjects must meet the disease conditions of one or both of the two cohorts listed below on or after Jan 1, 2004 and prior to Mar 12, 2014. If subjects had more than one study-qualifying episode of these disease conditions on or after Jan 1, 2004 and prior to Mar 12, 2014, only the most recent qualifying episode should be included:
• Cohort A: allogeneic hematopoietic cell transplantation (HCT) recipients who were at risk of progression to disseminated AdV disease, defined as documented evidence of 1) asymptomatic AdV viremia ≥ 1,000 copies/mL, increasing, OR 2) localized AdV infection
• Cohort B: allogeneic HCT recipients with disseminated AdV disease

Exclusion Criteria:

• Prior use of BCV
