Summary
Brief summary
This is a Phase II, multicenter, open-label, randomized, standard of care (SOC) controlled,
multiple ascending dose study to assess the safety and tolerability of IV Brincidofovir (BCV)
in subjects with BKV infection after kidney transplantation. The study will be conducted at
multiple study sites in several countries including Australia and Japan. Subjects who meet
eligibility criteria will be enrolled in the study and will be randomized and assigned to BCV
or SOC (defined as use of the same immunosuppressant administered during prescreening) before
receipt of the first dose of study drug in both the Dose Escalation Phase and the Expansion
Phase.
