Study acronymTRAPHICC
Study objectivesThe overall aim of this proof of concept study is to serve as a pilot study for a multicentre study powered to detect improvement in Intensive Care Unit (ICU) mortality by giving aciclovir prophylaxis to prevent Herpes Simplex Virus (HSV) infection in the lungs.

As of 01/06/2009 this record has been updated to include an extension to the anticipated end date; the initial end date at the time of registration was 31/05/2008.
Ethics approval(s)Multi-Centre Research Ethics Committee for Scotland (Committee A) approved on the 28/03/2008 (ref: 06/MRE00/14; Protocol Number: 3; EudraCT Number: 2006-000612-24).
Health condition(s) or problem(s) studiedHerpes simplex virus infection of the lower respiratory tract in critically ill patients
InterventionAdministration of 15 mg/kg per day aciclovir or placebo by infusion three times daily over 1 hour
Intervention typeDrug
Pharmaceutical study type(s)
PhaseNot Specified
Drug / device / biological / vaccine name(s)Aciclovir
Primary outcome measureThe primary endpoint is the mean change in Karnofsky index from baseline to day 28 +/- 2 days and 90 +/- 2 days after entry to the study
Secondary outcome measures1. Proportion of patients with HSV detected during ICU stay in lower respiratory secretions; proportion of patients with HSV detected during ICU stay in blood samples
2. In patients in whom HSV is detected during ICU stay, proportions of infections due to primary infection and reactivation of latent infection
3. At each sampling time point, the correlation between HSV lymphocyte response and viral titres
4. Mean plasma soluble cytokine levels in patients with and without HSV infection; mean respiratory secretion soluble cytokine levels in patients with and without HSV infection
5. Proportions of patients with HSV reactivation according to type of cytokine response
6. Mean complement activation before HSV is detected, after HSV detection and in patients where HSV is not detected during ICU stay
7. Proportion of patients in whom each of Cytomegalovirus (CMV), Epstein-Barr Virus (EBV), Human Herpes Virus Six (HHV6) and Human Herpes Virus Seven (HHV7) infections are detected during ICU stay
8. Median number of days on ventilation, median ICU stay, frequency of prescription of each of anti-retroviral agents, corticosteroids, immunosuppressive agents
9. Proportion of patients surviving at 90 days following ICU admission
10. Number of days of survival following ICU admission
11. The survival time for patients surviving beyond 90 days will be censored at 90 days
12. Proportion of HSV infections which are HSV1, proportion of HSV infections which are HSV2
13. Mean vital signs, white cell count and creatinine clearance during ICU stay
14. Reporting of adverse events occurring during randomised treatment or during the 7 days following the end of randomised treatment
Overall study start date01/06/2006
Completion date30/09/2009
