Abstract

Background. Everolimus-based quadruple low calcineurin inhibitor (CNI) maintenance immunosuppression has been shown to be effective in preserving short-term renal function without compromising efficacy or safety after lung transplantation;however, long-term benefit remains unknown. Methods. An investigator-initiated 5-y follow-up analysis of the 4EVERLUNG study (NCT01404325), comparing everolimus-based quadruple low CNI with standard triple regimen, was performed. Patients who remained on the randomized drug regimen until the end of the 5-y observation were analyzed as the per protocol (PP) population. Patients in whom the assigned regimen was switched were analyzed as the intention-to-treat (ITT) population. Results. In total, 123 patients (95%) from the core study were analyzed. During the observation period in 11 patients (19%) of the standard triple regimen and in 30 patients (46%) of the quadruple low CNI regimen, the assigned immunosuppressive regimen was switched (P = 0.002). Estimated glomerular filtration rate at 5-y follow-up did not differ between the groups in both the ITT (56 [48-73] versus 58 [48-69] mL/min;P=0.951) and PP (59 [50-73] versus 59 [48-69] mL/min;P = 0.946) populations. Thromboembolic events occurred more frequently in the quadruple low CNI regimen (ITT: 11% versus 24%, P = 0.048;PP: 11% versus 22%, P = 0.162). There was a trend for a higher chronic lung allograft dysfunction-free survival for the quadruple low CNI regimen in the PP population (P = 0.082). No difference in the graft survival was found. Conclusions. Initiation of an early everolimus-based quadruple low CNI regimen may have no long-term benefit on renal function. The immunosuppressive efficacy and safety profile seems comparable with the standard triple regimen.
