Cytomegalovirus Infections Clinical Trial
Official title:
A Prospective, Open, Dose-escalation, Multi-center, Phase 1 Trial to Evaluate Tolerability and Safety of Intramuscularly Administered BD03, a DNA Vaccine for Prevention of CMV and BKV Reactivation in Kidney Transplant Recipient
This study is a phase I, open-label study to determine recommended phase 2 dose (RP2D) for the BD03 vaccination in kidney transplant recipients. The recommended dose will be selected based on the safety and tolerability profiles observed.
It is reported that CMV and BKV infection and/or reactivations are associated with mortality
and morbidity of kidney transplant recipient, and occurrence of PyVAN in kidney transplant
recipients.
BD03 is a DNA vaccine that consists of 3 plasmid DNAs encoding CMV antigens, BKV antigens and
genetic adjuvant. It is expected to express antigen specific T-cell immune response, and
ultimately prevent activation of both viruses. Plasmid DNA that encode CMV and BKV antigens
are fused with tPA and Flt-3L to promote antigen specific immune response.
Patient scheduled to receive kidney transplant from living donor are enrolled in this study.
Eligible subjects will receive BD03 intramuscularly by electroporator three times on 6 weeks
and 2 weeks prior to kidney transplant and 2~4 weeks after the transplant.
This study will be comprised of 3+3 dose escalation scheme and starting dose is 0.6mg and
dose will be increased to 2mg and 6mg.
Occurrence of dose limiting toxicities observed until 1 week after second injection (1week
before kidney transplant) will guide whether to increase a dose.
After third injection of BD03, follow up visits are done for 18 weeks.
