Plain-language summary
This was a randomized, double-blind, double-dummy, parallel-group, multicenter study of the efficacy, safety, and tolerability of oral brincidofovir (BCV) versus valganciclovir for the prevention of cytomegalovirus (CMV) disease in CMV-seropositive kidney transplant recipients who received antilymphocyte induction therapy.

Inclusion criteria
✓. Were male or female kidney transplant recipients who were ≥18 years of age (subject to local law/practice for clinical trial participation) and ≤14 days following their first or second renal allograft.
✓. Were at high risk of cytomegalovirus (CMV) infection, which for the purposes of this study, was defined as CMV-seropositive recipients who received lymphocyte depleting induction treatment with antithymocyte globulin (Thymoglobulin® or Atgam®) prior to or during the qualifying transplant.
✓. Had an estimated glomerular filtration rate of \>10 mL/min (Cockcroft-Gault equation) at screening based on local laboratory results.
✓. Were CMV viremia negative (i.e., "not detected") as measured by the designated central virology laboratory using the Roche COBAS® AmpliPrep/COBAS® TaqMan® CMV Test no more than 5 days prior to subject randomization, and at all prior assessments performed since transplant under local standard of care.
✓. Were able to ingest, absorb, and tolerate tablets.
✓. If male, was willing to use an acceptable contraceptive method(s) throughout the duration of his participation in the study, i.e., through Week 24.
✓. If female of childbearing potential, i.e., not postmenopausal or surgically sterile, was willing to use 2 acceptable contraceptive methods, 1 of which must have been a barrier method, throughout the duration of her participation in the study, i.e., through Week 24.
✓. Were willing and able to provide informed consent.

✕. Had suspected CMV disease (either syndrome or tissue-invasive disease) or detectable CMV viremia by the central virology laboratory prior to the first dose of study drug.

✕. Had an absolute neutrophil count of \< 500 cells/μL, platelet count of \< 25,000 platelets/μL, or hemoglobin of \< 8 g/dL at screening.
✕. Had hypersensitivity (not including renal dysfunction or an eye disorder) to valganciclovir (vGCV), ganciclovir (GCV), cidofovir (CDV), or brincidofovir (BCV) or their excipients.
