A Study of CMV Vaccine (HB-101) in Kidney Transplant Patients


Brief description of study

HB-101 is a bivalent recombinant vaccine against human CMV infection. This is a randomized, placebo-controlled, phase 2 study to assess the safety, reactogenicity, immunogenicity, and efficacy of HB-101 in CMV-Seronegative patients receiving a kidney transplant from a CMV-Seropositive living donor and CMV-Seropositive patients.Patients enrolled should have a living donor kidney transplantation ideally planned between two to four months after the first injection of study drug (HB-101 or placebo).

Detailed Study Description

This is a randomized, placebo-controlled, phase 2 study to assess the safety, reactogenicity, immunogenicity, and efficacy of HB-101 in adult patients awaiting kidney transplantation. For Groups 1 and 2, adult CMV-seronegative (-) patients awaiting kidney transplant from a CMV-seropositive (+) living donor will be enrolled according to treatment intent with regard to the method of CMV prevention after transplant (either preemptive or prophylactic). This will be defined at study enrollment by the investigator and institutional standards. Patients enrolled in Group 1 and 2 will be randomized to receive HB-101 or placebo. For Group 3, adult CMV-seropositive (+) patients awaiting kidney transplant from either CMV-seropositive(+) or CMV-seronegative(-) living donors will be enrolled. Group 3 will be open label where all patients will receive HB-101. The post transplant management for Group 3 patients will also follow either preemptive or prophylactic method per the institution standards. The intent of the study is to administer three doses of the study drug (HB-101 or placebo) prior to transplantation and within proximity to the time of transplantation. However, two doses of study drug will be sufficient for the patients to be included in the efficacy analyses if a third dose of study drug is not feasible due to transplantation timelines. Patients will not receive study drug after transplantation. Patients will be recruited globally from transplant centers. The total duration of the study of each patient participating in the study will be approximately 15 months.
