Shingrix in Recipients of Allogeneic Transplants

Phase 2

Recruiting

• Conditions: Stem Cell Transplant; Bone Marrow Transplant
• Interventions: Drug: Zoster Vaccine Recombinant

• Registration Number: NCT05775718
• Lead Sponsor: University of Colorado, Denver

Brief Summary

This research is designed to determine if the adjuvanted recombinant glycoprotein E (gE) herpes zoster (HZ) vaccine (Shingrix) has acceptable immunogenicity and safety in people who have undergone allogeneic stem cell transplant (allo-SCT). Specifically, it will determine the effect of the interval after transplantation on the immune response and if an additional dose of vaccine is needed to improve the vaccine-induced responses.

Detailed Description

This is a phase II, single center, prospective, unblinded, immunogenicity and safety study. It is anticipated that enrollment will take approximately 6 months. Duration of participation for study subjects is approximately 1 year. During this interval, participants will continue to receive clinical care from the BMT center, which will ensure retention.

Participants will be recruited at their routine clinic visits, which take place every 6 months post-transplantation, or will be recruited by phone. Participants will be consented by study personnel in coordination with the BMT health care providers and subsequently followed in Dr. Levin's Vaccine Research Clinic, where they will also receive the 3rd dose of vaccine.

Arm && Interventions

Group	Intervention	Description
2-<3 years post stem cell transplant	Zoster Vaccine Recombinant	At Visit 1 participants will be given information about the nature of HZ and its recognition and given a questionnaire for completion should they develop HZ during the study. They will also be asked to contact the study team if they develop HZ so that further evaluation of potential HZ is completed and the details of the event recorded. A swab of an active lesion or crust from a dried lesion will be obtained for VZV PCR. A participant who develops HZ will be asked to complete the questionnaire weekly for 4 weeks and then at 8 and 12 weeks. In addition, the subject will be asked about pain medications taken during the episode. Information on HZ incidence will be supplemented from the clinic medical records and the electronic medical records. Subjects will be followed for 1 year after enrollment for the occurrence of HZ and of post-herpetic neuralgia (PHN).
