Abstract Background:Immunosuppression including high dose calcineurin-inhibitors (CNI) is essential after lung transplantation. Dosing is usually guided by therapeutic drug monitoring adjusted to target trough levels of CNIs to keep the balance between over-dose causing severe toxicity and increased risk of infections or under-dose with risk of graft-injury.Adaptation of CNI-based immunosuppression by monitoring of Torque-Teno-Virus (TTV) – a latent nonpathogenic DNA virus, measured in whole blood in addition to conventional therapeutic drug monitoring may reduce toxicity of immunosuppression with similar efficacy.Methods/Design:An open-label, randomized, controlled, parallel-group, multicenter trial in lung transplant recipients will be conducted to investigate the safety and efficacy of immunosuppression guided by TTV monitoring as add-on to conventional therapeutic drug monitoring. Adult lung transplant recipients 21 - 42 days after transplantation are eligible to participate. Patients (N = 144) will be randomized 1:1 to the experimental intervention (Arm 1: Immunosuppression guided by TTV monitoring in addition to conventional therapeutic drug monitoring of tacrolimus trough levels) and control intervention (Arm 2: conventional therapeutic drug monitoring). Outcomes will be assessed 12 months after randomization with the change in glomerular filtration rate as the primary endpoint. Secondary endpoints will be additional measurements on renal function, allograft function, incidence of acute rejections, incidence of chronic lung allograft dysfunction, graft loss and infections.Discussion:The results of this randomized controlled trial may reduce toxicity of immunosuppression after lung transplantation while maintaining efficacy of immunosuppression. Study results are transferable to all other solid organ transplantations.Trial registration: ClinicalTrials.gov, NCT04198506.
