Clinical Trial of Efficacy and Safety of the Combination of Reduced Duration Prophylaxis Followed by Immuno-guided Prophylaxis in Lung Transplant Recipients.

Registration Number
NCT03699254
Lead Sponsor
Maimónides Biomedical Research Institute of Córdoba
Brief Summary

To assess the efficacy of reduced duration prophylaxis followed by immuno-guided prophylaxis to prevent cytomegalovirus disease.

Detailed Description

Prolonged use of antivirals to prevent the development of cytomegalovirus (CMV) disease in lung transplant patients has been shown to have significant side effects, for which alternatives are being sought to reduce their use. The monitoring of cell immunity against CMV could be an alternative as it has shown to be useful in identifying transplant patients at low risk of infection, who could benefit from shorter prophylaxis. The aim of the CYTOCOR study is to demonstrate that the combination of a reduced prophylaxis strategy with subsequent CMV-specific immunological monitoring would allow CMV infection to be controlled in lung transplant patients as effectively as the usual strategy (prophylaxis followed by pre-emptive therapy), while reducing the side effects of antivirals due to the shorter duration of prophylaxis.

GroupInterventionDescription
ControlValganciclovirControl Group (universal prophylaxis + pre-emptive therapy; 6+6): The recommendation of the Spanish Consensus Document will be followed according to the strategy described below: * Universal prophylaxis with valganciclovir (900 mg/24h, corrected for renal function) up to month +6. The use of associated immunotherapy (e.g., anti-CMV hyperimmune immunoglobulin) will depend on each center's clinical practice. During this period, the treatment of blips of viral replication detected during the usual clinical follow-up of patients will depend oneach center's clinical practice. * Pre-emptive therapy guided by viral load from month +6 to month +12. For a viral load above\> 38 copies/mL (\> 35 IU/mL) and depending on each center's clinical practice, treatment with valganciclovir may be initiated (900 mg/12h, corrected for renal function).

The use of associated immunotherapy (e.g., anti-CMV hyperimmune immunoglobulin) will depend oneach center's clinical practice. During this period, the treatment of blips of viral replication detected during the usual clinical follow-up of the patients will depend on the each center's clinical practice. * Immuno-guided prophylaxis. This will consist of a monthly determination of cellular immunity by QF-CMV from month +3 to month +12.

Primary Outcome Measures
NameTimeMethod
Cytomegalovirus disease incidence rate at 18 months after lung transplantation.18 months after subject's transplantation.

Cytomegalovirus disease incidence rate at 18 months after lung transplantation.

Secondary Outcome Measures
NameTimeMethod
INFG cut-off point other than 0.2 IU/mL18 months after subject's transplantation.

For patients of the experimental group (3+9) in which immuno-guided prophylaxis is used based on QF-CMV Reactive (cut-off 0.2 IU/mL of IFNG) and who develop CMV disease, a secondary objective will be to assess whether an INFG cut-off point other than 0.2 IU/mL could predict protection against the disease more reliably.
