Comparison of Oral Valganciclovir and Placebo for the Prevention of Cytomegalovirus (CMV) After Lung Transplantation (Valgan)

September 25, 2024 updated by: Duke University

A Phase III, Randomized, Double-Blind Comparison of Oral Valganciclovir and Placebo for Prevention of CMV After Lung Transplantation

The study evaluated the efficacy and safety of a prolonged, continuous course of Valganciclovir (Valgan) in the prevention of CMV by comparing 3 months of Vaglanciclovir, the standard of care upon initiation of the study, to 12 months of Valganciclovir.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A multi-center two phase, double-blind, placebo controlled, randomized prospective study of 130 lung transplant recipients. Patients will be screened and consented prior to transplant. All consented patients will receive IV ganciclovir within 24 hours of transplant for not more than 14 days. Patients will enroll in Phase I of the study is an open label safety and efficacy analysis of three months of oral valganciclovir in adult transplant recipients who are at risk for CMV. After completion of 3 months of open label therapy, patients that meet the criteria for Phase II of the study will be randomized to 9 months of blinded therapy (Placebo/Valgan). Phase II of the study is designed to assess the efficacy of short course sequential IV ganciclovir followed by oral valganciclovir as compared to the extended period of oral valganciclovir prophylaxis in the prevention of CMV disease in at risk lung transplant recipients

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Incidence of CMV End Organ Disease
Time Frame: over the course of 300 days after randomization
The primary study end point was CMV end-organ disease determined by positive tissue immunostain or characteristic histopathology assessed for within 300 days post randomization.
over the course of 300 days after randomization
Incidence of CMV Syndrome
Time Frame: over the course of 300 days after randomization
CMV clinical syndrome, with either positive serum PCR or positive culture for CMV from bronchoalveolar lavage and at least 2 of the following: fever, leukopenia, thrombocytopenia, elevated liver function test results malaise, reduction in pulmonary function (FEV1) greater than 20percent of baseline, or radiographic infiltrate consistent with CMV (all in the absence of other causes)
over the course of 300 days after randomization

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Any CMV Infection

Inclusive of CMV syndrome, disease, or infection not meeting primary end point.
over the course of 300 days post randomization

over the course of 300 days of randomization
Non-CMV Infection
Time Frame: over the course of 300 days after randomization
non cmv opportunistic infections
over the course of 300 days after randomization
Severity of Viremia
Time Frame: over the course of 300 days after randomization
upon diagnosis of cmv disease, the number of CMV DNA copies/mL as measured by PCR
over the course of 300 days after randomization
Ganciclovir Resistance
Time Frame: over the course of 300 days post randomization
UL97 genotyping was done on all positive samples for CMV DNA at 1000 copies/mL, with resistance defined by the presence of 1 or more mutations shown by marker transfer to confer phenotypic ganciclovir resistance
