Conditions

COVID-19 is associated with increased morbidity and mortality in kidney transplant recipients (KTR) and patients with chronic kidneydisease (CKD). Therefore, potential efficacious SARS-CoV-2 vaccination would be of great clinical importance in these patients.However, SARS-CoV-2 vaccination studies have excluded KTR and patients with CKD so-far and it is unknown how long a possible antibody response will endure. This will be the subject of this trial. MedDRA version: 23.1 Level: LLT Classificati

Interventions

Trade Name: COVID-19 vaccine Moderna Pharmaceutical Form: Solution for injection/infusion INN or Proposed INN: Single-stranded, 5’-capped messenger RNA (mRNA) encoding the viral spike (S) protein of S

Design outcomes

Primary

MeasureTime frame
Secondary Objective: - To assess the antibody response at 28 days after SARS-CoV-2 vaccination in patients with chronic kidney disease stage G4-G5, on dialysis and in patients after kidney transplantation - To assess durability of the antibody response at 6 months after SARS-CoV 2 vaccination in patients with chronic kidney disease stage G4-G5, on dialysis and in patients after kidney transplantation - To assess the safety of vaccination ;Main Objective: To assess the efficacy of SARS-CoV vaccination by the incidence of COVID-19 in patients with chronic kidney disease stage G4-G5, on dialysis and patients after kidney transplantation who received SARS-CoV-2 vaccination;Primary end point(s): The incidence of COVID-19 in a two years period after SARS- CoV-2 vaccination in patients with chronic kidney disease stage G4-G5, on dialysis or after kidney transplantation.;Timepoint(s) of evaluation of this end point: Two years after SARS-CoV-2 vaccination

Secondary

MeasureTime frame
Secondary end point(s): • Efficacy: o The antibody based immune response to vaccination against COVID-19 at day 28 after the second vaccination. o The durability of the antibody response at 6 months after SARS-CoV 2 vaccination • Safety: • Incidence of mortality • Incidence of adverse events of specific interest as defined by (inter)national authorities • Incidence of a combined endpoint of acute rejection or graft failure in patients after kidney transplantation • Incidence of HLA antibodies defined as calculated Panel Reactivity Antibodies (cPRA) > 5% in dialysis patients on the waiting list for their first kidney transplantation ;Timepoint(s) of evaluation of this end point: Antibody response: 28 days and 6 months after vaccination Other endpoints over a period of 2 years
