A Study of CMV Vaccine (HB-101) in Kidney Transplant Patients
Cytomegalovirus (CMV) Infection, Kidney Transplantation
About this trial
This is an interventional prevention trial for Cytomegalovirus (CMV) Infection focused on measuring solid organ transplantation, vaccine
Eligibility Criteria
Inclusion Criteria:
Patients who meet all of the following key inclusion criteria will be eligible to participate in the study:
- Male or female patients 18 years of age or older.
- Patients must be eligible to undergo kidney transplantation from a living donor as per institutional standards.
- For Groups 1 and 2 only: Patients must be CMV immunoglobulin G (IgG) seronegative (-) and receiving kidney for transplantation from donors who are CMV IgG seropositive (+).
- For Group 3 only: Patients must be CMV immunoglobulin G (IgG) seropositive (+) and receiving kidney for transplantation from donors who are either CMV IgG seronegative (-) or seropositive (+).
- Patients who would comply with the requirements of this protocol (e.g., return for follow up visits), as judged by the investigator.
Exclusion Criteria:
Patients who meet any of the following key criteria will be excluded from the study:
- Patients planning to undergo multi-organ transplantation.
- Patients participating in another interventional clinical study.
- Previous vaccination with an investigational CMV vaccine.
- Any confirmed or suspected immunodeficiency disorder (based on medical history and physical examination) that could interfere with the immune response or that presents a risk for the patient to receive a vaccine candidate in development.
- Treatment with any chronic immunosuppressive medication or other immuno modifying drugs within 6 months prior to study entry. However, inhaled and topical steroids and low-dose oral corticosteroids (<10 milligrams a day of prednisone or equivalent) are allowed.
- Prior history of CMV disease or CMV infection requiring anti-viral therapy
- Patients with a rash, dermatological condition, or tattoo in the area of the injection site(s) that could interfere with administration site reaction rating. (Note: The injection site(s) can be the non-dominant arm [most preferred injection site], dominant arm, or either thigh [least preferred injection site], as judged by the investigator).
- It is anticipated that the patient will be unavailable to complete the study follow-up.
- Patients who are highly sensitized or who are likely to undergo desensitization at time of transplant (e.g., donor-specific antibody titers at the local laboratory >2000).

Three doses of HB-101 vaccine will be administered prior to transplantation and within proximity to the time of transplantation. However, two doses of HB-101 will be sufficient for the patients to be included in the efficacy analyses if an administration of the third dose is not feasible due to transplantation timelines. Post-transplant patients will be monitored per preemptive institutional standard.
Three doses of placebo will be administered prior to transplantation and within proximity to the time of transplantation. However, two doses of placebo will be sufficient for the patients to be included in the efficacy analyses if an administration of the third dose is not feasible due to transplantation timelines.

Post- transplant patients will receive 3-6 months anti-viral prophylaxis following institutional standard.
