The overall objective of this study is to establish a personalized test to measure individualized cytomegalovirus (CMV) specific immunity in lung transplant recipients in an effort to guide antiviral prophylaxis duration in clinical practice.
Targeted participants are those:
- enrolled in clinical research study CTOT-20 (Clinical Trials.gov ID: NCT02631720) who
- are CMV recipient positive by serology as determined using methods in accordance with current local organ procurement organization policies.

Cytomegalovirus (CMV) is a common virus. The virus is spread from one person to another through infected body fluids. In those with a normal immune system, CMV does not cause much of a problem. The immune system keeps the virus under control so most people do not have any symptoms. Once infected, the virus usually stays dormant (inactive) in the body for a person's entire life. This means some of the cells in the body are infected and the virus can become active again.
Lung transplant recipients take anti-rejection medicines to prevent the body from rejecting the transplanted lung(s). Although anti-rejection medications help protect the transplanted lung(s) from the body's immune system, these medications also decrease the body's ability to fight infections. This reduces the immune system's ability to control viruses like CMV. Many transplant recipients take an antiviral medication early after transplant to help the body control the CMV virus. This is the time that risk of infection would be highest. Sometimes recipients get an active CMV infection after stopping these medicines. If this happens, the infection is treated and monitored.
In this study, investigators are trying to determine whether a blood test can predict development of active CMV infection in lung transplant recipients. Specifically, the clinical research study will prospectively assess the performance of an immune signature based on the "ex vivo" measurement of T cell CMV specific immunity in predicting freedom from future CMV infections among recipient positive (R+) lung transplant participants receiving standard durations of valganciclovir prophylaxis.

CMV+ First Lung Transplant Recipients
Participants enrolled in one of four North American sites in clinical research study CTOT-20 (Clinical Trials.gov ID: NCT02631720) who are cytomegalovirus positive by serology (e.g., CMV Recipient positive).
Serial blood draws. Participants will be enrolled either pre-transplant or within 45 days post-transplant and will be followed over the course of 18 months post transplant. Protocol mandated serial measurement of cytomegalovirus (CMV)-specific immune signature will occur pre-transplant (as applicable) and at post-transplant timepoint months 2, -3, -6, -9, -12 and -18.
- Time from CMV Prophylaxis Discontinuation Post-Transplant to First Detection of CMV Infection or CMV Disease within 6 months Post CMV Prophylaxis Discontinuation [ Time Frame: From CMV Prophylaxis Discontinuation to 6 Months Post CMV Prophylaxis Discontinuation ]Participants will be evaluated for CMV infection or disease according to each center's standard of care clinical protocol. All centers have aligned their clinical practice to include, at a minimum, a CMV infection and a CMV disease assessment at the time of prophylaxis discontinuation, monthly for the first 6 months after discontinuation, and quarterly after that up to 18 months post transplantation.
- Time from CMV Prophylaxis Discontinuation Post-Transplant to First Detection of CMV Infection or CMV Disease Within 18 Months Post-Transplant [ Time Frame: From CMV Prophylaxis Discontinuation to 18-Months Post-Transplant ]Participants will be evaluated for CMV infection or disease according to each center's standard of care clinical protocol. All centers have aligned their clinical practice to include, at a minimum, a CMV infection and a CMV disease assessment at the time of prophylaxis discontinuation, monthly for the first 6 months after discontinuation, and quarterly after that up to 18 months post transplantation.
