Brief Summary:

This study will enroll individuals who have:

  • Completed, at a minimum, a full 2-dose course but no more than 4 of either the Moderna messenger RNA (mRNA) based coronavirus infectious disease 19 (COVID-19) vaccine or the Pfizer-BioNTech mRNA based COVID-19 vaccine, and
  • An antibody response ≤ 250 U/mL measured at least 30 days after the last dose of vaccine.

This group of patients is at high risk for severe COVID-19 disease due to pharmacologic immunosuppression and a high prevalence of non-transplant risk factors such as obesity and diabetes.


Condition or disease Intervention/treatment Phase
Kidney Transplant Recipients Liver Transplant Recipients Biological: Pfizer-BioNTech COVID-19 Vaccine Booster Biological: Moderna COVID-19 Vaccine Booster Drug: SOC IS Regimen Drug: SOC IS Reduction Phase 2

Detailed Description:

This study is a randomized, open-label multi-site trial designed to induce an enhanced antibody response to severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) in kidney and liver transplant recipients who have ≤ 250 U/mL anti-spike antibody (as measured by the Roche Elecsys® anti-SARS-CoV-2 S assay) after at least two mRNA COVID-19 vaccines.

Participants will be randomized to either:

  1. Receive an additional dose of mRNA based COVID-19 vaccine (booster) with no change in their immunosuppressive regimen, or
  2. Undergo a temporary, prescribed reduction in their maintenance immunosuppression (IS) regimen and receive an additional dose (booster) of mRNA-based COVID-19 vaccine.

Duration of study participation for interested and eligible individuals: 13 months.
