 Protocol: A Phase IB Pilot Trial of Herpesvirus Treatment in Idiopathic Pulmonary Fibrosis 
 
1. Summary 
1.1. Most patients with idiopathic pulmonary fibrosis (IPF) have progression to respiratory failure within a 
period of 3 - 5 years after diagnosis(1).  Unfortunately, only modestly effective therapies are available 
for patients with IPF, and these treatments do not reduce mortality or improve quality of life.  Over the 
last several years, our studies have focused on the concept that alveolar epithelial cells (AECs) play a 
critical role in the ongoing cycle of injury and repair that drives progressive fibrotic remodeling in IPF.  
Our preliminary data for this proposal suggest that reactivation of latent herpesviruses in AECs could 
be directly involved in progression of IPF.  As a result, we propose to study the effectiveness of 
targeted anti-herpesvirus treatment to reduce the burden of herpesvirus in the lungs and limit 
progression of the disease.   
1.2. A viral etiology of IPF was first suspected more than half a century ago, but identification of an 
important role for viruses in IPF pathogenesis has been challenging(2).  In 2003, our group used a 
PCR strategy for identification of all known herpesviruses in lung tissue samples and found that 97% of 
lungs from IPF patients contained herpesvirus DNA(3).  Importantly, viral proteins were expressed in 
AECs lining areas of fibrosis in IPF lungs, but were not detected in AECs in normal lungs.  To 
investigate the prevalence of herpesvirus antigens in AECs of IPF patients, we performed IHC on lung 
sections from 34 individuals with IPF and 10 normal control lungs for cytomegalovirus (CMV) and 
Epstein-Barr virus (EBV), the most common herpesviruses in the lungs of IPF patients.  We identified 
expression of EBV and/or CMV proteins, which is indicative of chronic infection or viral reactivation, in 
AECs from 29/34 patients (85%) with IPF and 0/10 normals.  We also showed that expression of 
herpesvirus antigens in IPF co-localizes with markers of endoplasmic reticulum (ER) stress, which is 
common in IPF and may contribute to AEC dysfunction and apoptosis(4).  Recently, we identified DNA 
for CMV and EBV in cell-free fluid obtained by bronchoalveolar lavage (BAL) from IPF patients and 
controls.  Using standard PCR to identify DNA for EBV and CMV in concentrated DNA from cell-free 
BAL, we found that 21/28 IPF subjects were positive for CMV and 6/28 were positive for EBV DNA 
(23/28 were positive for at least one herpesvirus).  Taken together, these data suggest that 
herpesvirus infection of alveolar epithelial cells is common in IPF and could contribute to fibrosis.  
1.3. In addition to the considerable evidence implicating herpesviruses in human IPF, a number of animal 
model studies have also indicated that herpesviruses could play a pathogenic role in lung fibrosis(5, 6).  
Given this combination of evidence for a role for herpesviruses in IPF and the fact that oral treatments 
for herpesviruses are already available with a proven track record, we propose this timely study 
evaluating the effectiveness of anti-herpesvirus treatment in IPF.   
 
2. Hypothesis: Addition of valganciclovir to standard IPF treatment has an acceptable safety and tolerability 
profile. 
 
3. Specific Aims   
3.1 To determine the safety and tolerability of oral valganciclovir as add-on therapy in patients with IPF 
tolerating standard treatment with pirfenidone. 30 individuals with a diagnosis of IPF and positive serology 
for EBV or CMV will be enrolled in this study at Vanderbilt University Medical Center and randomized to 
receive either valganciclovir or placebo in a 2:1 ratio for 12 weeks, The primary endpoint will be rate of 
discontinuation of study drug due to adverse events in subjects randomized to valganciclovir compared to 
placebo. In addition, we will compare type, frequency and duration of adverse events (AE) and serious 
adverse events (SAE) between valganciclovir and placebo subjects.  
3.2 To investigate the effect of anti-herpesvirus treatment on changes in viral load and immune responses 
against herpesvirus.  A subset of study subjects will undergo bronchoscopy with BAL at the time of study 
entry and at 12 weeks for measurement of: 1) immune response to herpesviruses in lung lymphocytes and 
2) herpesvirus DNA in cell-free BAL fluid.  Additional studies to investigate changes in the immune 
response in peripheral blood lymphocytes to herpesviruses will include: 1) analyzing PD-1 expression by T 
lymphocytes and 2) quantifying CD8+ T cell immune responses to herpesvirus antigens at study entry and 
after 12 weeks of therapy.  These parameters will be reassessed at 6 months and 1 year after study entry 

 
 
to determine whether changes in anti-herpesvirus immune responses persist or revert to pre-treatment 
levels, thus shedding light on the duration of therapy needed to potentially alter disease progression.  
 
4. Endpoints 
4.1. Primary Endpoint 
4.1.1. The primary outcome will be safety and tolerability will be determined by type, frequency and 
duration of adverse events (AE) and serious adverse events (SAE) in subjects receiving valganciclovir 
versus placebo.  
 
4.2. Secondary Endpoints: We will evaluate for trends in other clinical endpoints, as well as viral and 
immune endpoints over time in the valganciclovir group compared to the placebo group. 
4.2.1. 
We will determine the change in pulmonary function tests including forced vital capacity 
(FVC) and diffusing capacity for carbon monoxide (DLCO) in the valganciclovir treated group 
compared to placebo during active treatment and post-treatment follow-up. PFTs will be 
measured at baseline, 3 months (12 weeks), 6, 9 and 12 months after randomization to 
determine the FVC slope (change in FVC over time) and change in diffusion capacity (DLCO). 
4.2.2. 
We will determine the effect of valganciclovir therapy on viral load in cell-free BAL fluid.   
4.2.2.1. 
We will evaluate the change from baseline in daytime oxygen requirements. Oxygen 
requirements will be measured at study visits baseline, 3, 6, 9, 12 months. At each study 
visit, while at rest, the subject will be placed on the amount of supplemental O2 required at 
the enrollment visit.  After 5 minutes, the SpO2 on this supplemental flow rate will then be 
recorded and evaluated in comparison to baseline. In addition, the patient will have his/her 
supplemental oxygen requirement determined to maintain oxygen saturation ≥ 88% at rest.  
The change in liters per minute flow rate in oxygen compared to baseline will be recorded. 
4.2.3. 
Exercise capacity will be determined on the basis of the 6 minute walk test (6MWT).  
The principal exercise capacity measurement will be the change in distance until SpO2 
reaches 80% compared to baseline.  6 MWT will be measured at study visits baseline, 3, 6, 9, 
12 months.  The 6MWT will be performed using a standardized protocol while the subject is 
breathing room air (i.e. without supplemental oxygen).   
4.2.4. 
Additional secondary endpoints will analyze the immune response to herpesviruses by 
analyzing PD-1 expression by T lymphocytes and quantifying CMV- and EBV-antigen specific 
CD8+ T cell immune responses. 
 
5. Background and Significance 
5.1. Idiopathic pulmonary fibrosis - current status:  IPF is a chronic progressive lung disease characterized 
by the insidious onset of interstitial infiltrates in the lung parenchyma associated with progressive 
dyspnea and impaired pulmonary function.  Estimates for prevalence suggest that approximately 20 
per 100,000 males and 13 per 100,000 females have the disease, and depending on the criteria used 
to define IPF, the disease may have a higher prevalence(1).  The clinical definition of IPF requires 
exclusion of other known causes of interstitial lung disease, and its diagnosis requires characteristic 
changes on high-resolution computed tomography (HRCT), restriction on pulmonary function testing, 
impaired gas exchange, and absence of an alternative diagnosis on transbronchial biopsy or 
bronchoalveolar lavage (BAL)(11).  Absolute confirmation of IPF by histologic diagnosis requires a 
surgical lung biopsy.  The pathological equivalent of IPF is described as usual interstitial pneumonia 
(IPF/UIP).  Of the Idiopathic Interstitial Pneumonias, IPF/UIP is the most common (70% of total) and 
most severe, so it is the form targeted in treatment trials(12).  RCTs of interferon β and γ, bosentan, 
and sildenafil in IPF patients have been either negative or have shown inconsistent results, and there 
were no FDA approved therapies(13-17) until the recent approval of pirfenidone and nintedanib (18, 
19).  To date, clinical trials in IPF have been based on the premise that inhibition of inflammation or 
collagen deposition would be of benefit, or that treatment directed to the pulmonary vasculature would 
limit disease progression.  In contrast, we suggest that therapy aimed at decreasing AEC injury and 
preserving alveolar epithelial function could be an effective approach. 
5.2.  Environmental factors in IPF:  There are several lines of evidence that environmental factors are 
important in IPF.  The lungs are continuously exposed to the environment and are at constant risk of 
microscopic and macroscopic environmental lung injury.  A pathologic hallmark of IPF/UIP is spatial 

 
 
and temporal heterogeneity of fibrotic remodeling.  This feature is consistent with multiple episodes of 
microscopic lung injury by environmental stressors.  Environmental risk factors linked to IPF in 
epidemiological studies include cigarette smoking(21), inhaled particulates(22), metal dust(23, 24), 
wood dust(23), and viral infections.  Cigarette smoking has consistently been associated with 
increased risk for IPF with odds ratio from case-control studies ranging from 1.11-3.23.  In addition to 
inhaled irritants, several viruses including adenovirus and herpesviruses have been associated with 
IPF(2, 3, 25, 26).  A common feature of all these environmental factors is the ability to injure the 
alveolar epithelium.  Interestingly, cigarette smoke(27, 28), inhaled particulates(29), and 
herpesviruses(30, 31) have all been shown to induce endoplasmic reticulum (ER) stress in lung 
epithelium, which we believe is an important underlying abnormality in IPF that predisposes to injury 
and limits recovery of the epithelial barrier.   
5.3. Alveolar Epithelium in IPF:  Our current concept for the pathogenesis of IPF is repeated injury of the 
alveolar epithelium followed by incomplete epithelial repair that results in an aberrant wound healing 
response, leading to pulmonary fibrosis.  A variety of studies have emphasized the role of the alveolar 
epithelium in both clinical IPF and animal models of lung fibrosis.  In lung biopsies from patients with 
IPF, epithelial abnormalities are common and include hyperplastic type II AECs and bronchiolar-like 
epithelial cells lining areas of honeycombing(32).  The importance of AECs in IPF is highlighted by the 
identification of mutations in the epithelial-restricted genes, surfactant protein C (SFTPC) and SFTPA2, 
that are associated with Familial Interstitial Pneumonia (FIP), the familial form of IPF(33, 34).  AECs 
engineered to express mutant forms of these genes result in protein products that are misfolded and 
accumulate in the ER, induce ER stress, and alter cell survival(35, 36).  In 2008, we evaluated human 
lung tissues samples from FIP patients with a mutation in SFTPC (L188Q), FIP patients without 
SFTPC mutations, and sporadic IPF patients for expression of ER stress markers(4).  These ER stress 
markers were prominently expressed in AECs lining areas of fibrosis in patients with SFTPC mutations 
as well as patients with lung fibrosis in the absence of SFTPC mutations.  Subsequently, Korfei et al 
reported that AECs lining areas of fibrosis in IPF lung tissue sections not only had expression of ER 
stress markers, but these same cells also had activation of pro-apoptotic pathways(37).  Recently, we 
developed a mouse model in which a mutant form of SFTPC is inducibly expressed in type II 
AECs(38).  Such expression leads to ER stress in the type II AEC population, but these cells are able 
to maintain homeostasis in the setting of ER stress without the development of lung fibrosis.  However, 
following low dose bleomycin, these mice develop excessive lung fibrosis.  In a separate model, we 
induced ER stress in the lungs of wild type mice by intratracheal administration of tunicamycin(38).  As 
with mutant SFTPC expression, ER stress alone did not cause lung fibrosis, but did predispose to 
greater bleomycin induced fibrosis.  Taken together, these studies suggest that underlying ER stress 
leads to a vulnerable AEC population with predisposition to fibrosis after injury; however, a ‘second hit’ 
is necessary for development of lung fibrosis.  We suggest that genetic predisposition and/or recurrent 
environmental stimuli render AECs vulnerable to a ‘second hit’ such as re-activation of herpesvirus that 
result in a pro-fibrotic cascade in the lung parenchyma.  
5.4. Herpesvirus infection in IPF:  Reports from several laboratories have demonstrated a striking 
association between herpesvirus infection in the lung and IPF.  Increased titers of antibodies to 
cytomegalovirus (CMV) and Epstein Barr viral capsid antigen (EBV VCA) have been reported in 
patients with IPF and collagen vascular disease-related interstitial pneumonitis compared with 
controls(2).  Using PCR for EBV DNA and immunohistochemistry (IHC) for EBV proteins, EBV VCA 
and LMP-1 (latent membrane protein 1) have been identified more frequently in biopsies from IPF 
patients than controls and only biopsies from IPF patients were positive by both IHC and PCR(26).  
Our group extended these investigations to identify all known herpesviruses by PCR for viral DNA.  
CMV, EBV, and Kaposi’s sarcoma associated herpesvirus (KSHV, HHV-8) were present significantly 
more frequently in IPF lungs than controls, with 97% of IPF patients positive, whereas two other 
viruses reactivated by immunosuppression were not found(3).  Furthermore, only IPF patients 
demonstrated co-infection with two or more herpesviruses.  An important finding in these studies was 
that viral proteins were highly expressed in the abnormal airway epithelial cells lining distended 
airspaces in areas of honeycombing. 
 
 
6. Protocol Design and Methods 

 
 
 
6.1 Study design:  We propose to conduct a single-center, prospective, randomized, placebo-controlled, 
double-blind pilot study of anti-herpesvirus therapy in patients with IPF.  Patients with mild, moderate or 
severe IPF will be considered for study inclusion.  
Randomization will be to pirfenidone plus placebo or 
pirfenidone plus valganciclovir. We prefer to have all 
subjects on pirfenidone as the standard of care for this 
study since the majority of patients elect to be treated 
with pirfenidone in our clinic. In addition, we anticipate 
valganciclovir will be better tolerated in combination with 
pirfenidone.  We propose to enroll and randomize all 
eligible subjects with evidence of current or past EBV or 
CMV infection as determined by serologic testing for anti-
EBV and CMV antibodies (total n=30) to treatment with 
pirfenidone plus valganciclovir (20 patients) or pirfenidone 
plus placebo (10 patients) for 12 weeks (Fig. 1).  In order 
to maximize exposure to active treatment and assess for 
safety and tolerability, randomization will be 2:1 
valganciclovir vs. placebo. The primary outcome will be 
safety and tolerability will be determined by type, 
frequency and duration of AE and SAEs.  All study 
subjects will be offered bronchoscopy with BAL at study 
initiation and upon completion of treatment (12 weeks). 
Subjects will then be followed up at routine clinic visits at 6, 
9 and 12 months for data collection.   
 
6.2 Rationale for Blinding and Placebo: 
6.1.1. 
A RCT is necessary given the clinical heterogeneity of IPF, and the inability to have two 
similar arms without randomization.  A placebo arm will minimize bias since GI upset is a side 
effect of valganciclovir and standard treatment, pirfenidone.  All subjects will be provided 
standard of care treatment to be applied equally across study groups as much as feasible and 
blinding will help avoid bias in the care provided. 
6.1.2. 
 Blinding is necessary to have optimal scientific validity, to make objective assessments 
of treatment effects, and to minimize dropout rates across study arms.  In this study, there is 
particular concern that without blinding, subjects may opt to obtain off-label anti-viral therapy 
from non-study physicians if they become aware of the presence of herpesviruses in their 
lungs.

8. Study Drug 
8.1. Dose justification of valganciclovir:  The standard dosing of valganciclovir for CMV disease when there 
is active pneumonitis with histopathologic changes such as intracellular inclusions, positive IHC, and 
acute inflammation is 900 mg twice daily(42).  Typically, this occurs in solid organ or bone marrow 
transplant recipients, and is associated with viremia with viral loads in blood in the range of 10,000-
100,000 viral genomes/ml(43). This dose is typically given for 21 days, and can be reduced 900 mg 
daily to further reduce low-grade viremia (200-2,000 copies/ml), and 900 mg/day can be given long 
term to prevent relapse or recurrent CMV disease(42).  In IPF patients, CMV viral load in BAL is below 
10,000 genomes/ml.  Hence, the overall viral load is much lower in IPF patients compared to solid 
organ transplant recipients.  Consequently, we believe a dose of 900 mg/day comparable to that used 
for chronic suppressive therapy in solid organ transplant recipients is most appropriate.  A dose of 900 

 
 
mg/day is generally well tolerated when administered for several months(42), and avoids the bone 
marrow suppression effects of long-term 900 mg twice daily dosing. Standard dosing of this regimen 
will be 900 mg once daily. 
8.2. Justification of treating concomitant EBV and CMV with valganciclovir:  Valganciclovir has activity 
against EBV and CMV.  The 50% inhibitory concentration of valganciclovir against EBV is 1.5 
mcg/ml(44), and the median area under the concentration versus time curve for 900 mg valganciclovir 
over 24 hrs (AUC 0-24) is 29 μg/ml with a peak concentration of 4.4 μg/ml(45).  Hence the average 
concentration of valganciclovir is above the IC50 of EBV.  We believe that monotherapy with 
valganciclovir should be effective and safe for subjects with CMV and EBV.   
8.3.  Protocol for dosage adjustment: In subjects who develop a treatment-emergent, nonserious adverse 
events (i.e. nausea), valganciclovir will be administered in divided doses (450 mg twice daily).  In 
subjects who develop treatment emergent clinically significant laboratory abnormalities possibly 
related to the study drug, study drug will be held until lab abnormalities have resolved.  Current and 
new medication review will be conducted to assess for alternative contributors to lab abnormalities.   
After the treatment-emergent laboratory abnormality resolves, subjects will then resume study drug 
with repeat laboratory monitoring within 1 week after resumption of treatment, or earlier if symptoms 
recur in an earlier time period.  If the treatment emergent laboratory abnormality recurs, study drug will 
be reduced to 450mg QD with close monitoring.  If symptoms or lab abnormalities occur with 450mg 
QD, the study drug will be terminated. 
 
9. Study Feasibility and Timeline 
All subjects will be enrolled through the Vanderbilt Interstitial Lung Disease (ILD) clinics have been top 
enrolling sites for several multi-center clinical trials in IPF, and given this proven track record, we are 
confident we will meet enrollment targets.  We will place priority on enrollment in this VICTR support 
pilot trial over industry-sponsored trials.  We currently evaluate >200 new IPF cases per year in our 
clinics.  At the present time, approximately 125 IPF patients are being treated with pirfenidone in the 
Vanderbilt ILD clinic, and the majority of these patients should be eligible for this study. We expect to 
begin recruiting patients immediately upon approval of this study and complete enrollment within 9 
months such that subjects will reach the primary study endpoint by the end of Year 1. Ongoing 
ascertainment of data collected during routine clinical follow-up of these study subjects will then be 
completed in Year 2.   
 
10. Study Visits 
10.1. 
Screening visit: Once informed consent is obtained, subjects may begin the screening process.  
If a study subject has been evaluated at VUMC by a study physician and has performed clinical testing 
that meets study guidelines within 30 days, then this testing maybe used to qualify for study entry.  
This will facilitate entry into the study, avoid repeated testing, and reduce costs.  The following 
procedures will be performed at screening: 1) medical history and physical examination; 2) vital signs 
including oximetry; 3) blood chemistries, hematology counts; EBV and CMV serology 4) PFTs 
including spirometry, lung volumes, and diffusing capacity; 5) HRCT review; 6) surgical lung biopsy 
review; and 7) recording of current medications.  If patients are not taking pirfenidone at the time of 
screening, then patients will be placed on pirfenidone and will be re-assessed to determine study 
eligibility 4 weeks later to allow ample time to determine tolerance to pirfenidone. 
10.2. 
Enrollment visit:  For subjects who meet eligibility criteria, enrollment may occur the same day 
as the screening visit. For subjects who require blood tests to be drawn at the screening visit, they will 
be notified by telephone of their eligibility for the study and study drug will be mailed to subjects by the 
investigational drug pharmacy. Randomization will be 2:1 valganciclovir versus placebo.  Subjects will 
be offered the opportunity to undergo an optional research bronchoscopy. For subjects who undergo 
bronchoscopy, study drug will begin immediately following the bronchoscopy. Subjects who do not 
undergo bronchoscopy will begin study drug immediately. Additional tests that will be obtained are the 
following: 1) six minute walk test (6 MWT); 2) baseline blood chemistries and blood counts if >30 days 
after the screening visit; 3) baseline blood draws for biomarker and immunology studies, including 
HLA-typing; 4) teaching subjects self-monitoring and diary recording; and 5) optional bronchoscopy 
with BAL.  Bronchoscopy will be the last test performed at enrollment.   

 
 
10.3. 
Week 4 and 8 study visits:  The primary purpose of these visits is to establish safety of study 
treatment and adherence to study treatment.  Subject’s diaries will be reviewed, medical history and 
physical examination will be performed, a pill count will be performed, current medications will be 
recorded, and chemistries and hematology counts will be obtained.  
10.4. 
Week 12 study visits:  This visit will conclude active treatment in the study and will be the 
primary endpoint for safety and tolerability. In addition, 6 MWT, and oximetry will be performed at this 
study visit.  Subject’s diaries will be reviewed, medical history and physical examination will be 
performed, PFTs will be obtained according to usual clinical care protocol, a pill count will be 
performed, current medications will be recorded, chemistries/hematology counts will be obtained, and 
blood will be obtained for biomarker and immunology studies. Subjects who consent to research 
bronchoscopy will undergo a second research bronchoscopy coordinated with the week 12 study visit.  
10.5. 
Week 16 telephone call: 4 weeks after the final study visit (week 12), subjects will be contacted 
by telephone to review any side effects that occurred while taking study drug. 
10.6.

11. Data Collection for Specific Aims 
11.1. 
Aim 1: To determine the safety and tolerability of oral valganciclovir as add-on therapy in 
patients with IPF tolerating standard treatment with pirfenidone. 
11.1.1. 
Rationale:  This study is designed to assess for safety and tolerability of valganciclovir in 
IPF patients who are taking standard therapy for IPF (pirfenidone) as assessed by type, 
frequency and duration of AE and SAEs. Exploratory secondary analysis to evaluate for clinical 
efficacy will include changes in FVC slope of patients with IPF, oxygenation, and exercise 
capacity.  In addition to identifying whether anti-viral therapy could positively impact any of these 
parameters, collecting these data will ensure that any detrimental effects of the drugs used to 
treat herpesviruses on clinically relevant endpoints will be identified. Information will be collected 
as outlined below.  For analysis of all these variables, the standard treatment arm with 
pirfenidone and placebo will be compared to valganciclovir and pirfenidone. 
11.1.2. 
Evaluation for safety of valganciclovir. Assessment of safety will be determined by 
ongoing review of clinical laboratory tests (blood sampling for clinical laboratory parameters-see 
schedule of events), physical examination including vital sign measurements, functional status 
assessments and adverse events. Women of childbearing potential will undergo a urine 
pregnancy test at each study visit. 
11.1.3. 
Evaluation for treatment emergent adverse events. A treatment-emergent adverse event 
(TEAE) is defined as a sign or symptom that emerges during treatment or within the 12 weeks 
following the last dose of the study drug, having been absent pretreatment or that has worsened 
relative to the pre-treatment state. Any adverse event deemed related to study drug will also be 
considered a TEAE regardless of elapsed time since last study drug dose.  Adverse events will 
be graded using National Cancer Institute [NCI] CTCAE Version 3.0 during the study evaluation.  
Study drug-related adverse events will be listed individually. 
11.1.4. 
Evaluation for change in pulmonary function.  PFTs will be captured for all subjects using 
a CareFusion Sensormedics pulmonary function testing equipment (CareFusion, San Diego, 
CA), located in the VUMC pulmonary clinic.   Measurements will be performed according to 
current ATS/ERS guidelines(46), and include spirometry (FEV1 and FVC) by NHANES, total 
lung capacity by body box plethysmography, and diffusing capacity of the lung for carbon 
monoxide (DLCO) all by %predicted according to Crapo(47). PFTs will be performed by 
registered respiratory technicians who are experienced in clinical trials.  All registered 
respiratory technicians performing these measurements will be trained in this protocol  All 
subjects will perform measurements on one machine dedicated to the study to reduce variance.   
11.1.5. 
Change from baseline in daytime resting oxygen requirements.  Two measurements will 
be performed to determine if the research subject has a change in SpO2 or oxygen requirement 
at rest on each study visit.  At each study visit, any supplemental oxygen will be removed for 5 
minutes and SpO2 breathing ambient air will then be recorded and evaluated in comparison to 
baseline.  In addition, the patient will have his/her supplemental oxygen requirement determined 
to maintain oxygen saturation ≥ 88%.  The change in liters per minute flow rate in oxygen 
compared to baseline will be recorded.

11.1.6. 
Evaluation of exercise capacity.  Exercise capacity will be determined on the basis of the 
6 minute walk test (6MWT).  The principal exercise capacity measurement will be the change in 
distance until SaO2 reaches 80% from the 6MWT compared to baseline.  The 6MWT will be 
performed using current guidelines(48).  The walk is performed on room air throughout the 
study.  Patients on supplemental oxygen will be off oxygen for a period of 10 minutes prior to 
initiation of the walk.  Continuous finger pulse oximetry is performed during the test and the 
patient will walk at their own pace for as far as he/she can in the 6 minute duration.  
Measurements that will be collected include: 1) distance walked until SpO2 reaches 88%; 2) 
time until SpO2 reaches 88%; 3) distance walked to SpO2 reaches 80%; 4) time until SpO2 
reaches 80%; 5) pre-test SpO2; 6) post-test SpO2; 7) lowest SpO2 during test; and 8) total 
distance walked in 6 minutes; and 9) average velocity calculated as distance/time.  In subjects 
who desaturate to <88%, an oxygen titration study will then be performed to determine 
exertional oxygen requirement. This value will be recorded and compared to baseline. 
  
11.2. 
Aim 2: To investigate the effect of anti-herpesvirus treatment on changes in viral load and 
immune responses against herpesvirus.  
11.2.1. 
Experimental design: Determination of herpesvirus DNA in BAL.  BAL will be collected at 
bronchoscopy and the cell free portion will be used for determination of herpesvirus DNA.  Total 
DNA will be isolated by the following procedure.  After 10-fold concentration of cell free BAL 
fluid (10 ml), protein is digested overnight at 55°C in the presence of 500 μg/ml of proteinase K.  
DNA is then extracted with phenol/chloroform, followed by addition of 3 M sodium acetic acid 
(pH 6.5), precipitation in 100% isopropanol, and reconstitution in TE buffer.  Real time qPCR 
amplification is performed on a StepOne Plus Real Time PCR machine (Applied Biosystems) to 
determine viral load based on a standard curve derived from a plasmid vector containing CMV 
or EBV DNA.  Primer sequences used for CMV detection are as follows:  (forward) 5’-TGA AGC 
GCC GCA TTG A-3’, (reverse) 5’-TGG CCC GTA GGT CAT CCA-3’.  Primer sequences used 
for EBV detection are as follows:  (forward) 5’-CCC AAC ACT CCA CCA CAC C-3’, (reverse) 5’-
TCT TAG GAG CTG TCC GAG GG-3’.  Results are reported as herpesvirus genomes per ml of 
BAL fluid.     
11.2.2. 
Measurement of the anti-herpesvirus immune response.  All patients will be HLA typed 
at the beginning of the study.  Peripheral blood mononuclear cells (PBMCs) will be separated 
using standard Ficoll-Paque™ density centrifugation.  Lymphocytes from peripheral blood 
obtained at baseline, 12 weeks (3 months), 6 months, 9 months, and 12 months and BAL 
obtained at baseline and 12 weeks will be studied.  The following assays will be performed to 
quantify herpesviruses specific T-cell responses in subjects randomized to antiviral therapy or 
placebo:   
11.2.2.1. As a marker of chronic immune activation in response to herpesvirus infection, we will 
evaluate PD-1 expression on naive, central memory (TCM), effector memory (TEM), and 
terminal effector memory (TEMRA) populations using CCR7 and CD45RO to distinguish these 
memory T cell subsets.  In addition, we will directly evaluate CD8+ T cell immune responses 
to herpesvirus antigens using MHC Class I tetramer assays.  HLA-specific MHC-I CMV and 
EBV tetramers are available for individuals with HLA-A2, HLA-B7, HLA-B35, and HLA-B44 
serotypes (Glycotope Biotechnology, Heidelberg, Germany), which comprises ~80% of the 
U.S. Caucasian population.  Lymphocyte subsets will be separated by flow cytometry with 
anti-CD3 PerCPCy5, anti-CD8 FITC, anti-PD-1 Brilliant Violet 421, anti-CD45RO PECy5, and 
anti-CCR7 PE-CF594.  CMV or EBV HLA class I tetramers conjugated with APC or Cy7 will 
be used for these studies (for example, HLA-A2/pp65 tetramers for CMV and HLA-A2/LMP1 
tetramers; HLA-A2/LMP2 tetramers for EBV will be used for subjects with the HLA-A2 
genotype).  Live cells will be gated based on forward- and side-scatter properties, and 
analysis performed using FlowJo software (Tree Star, Ashland, OR), as previously 
described.  All experiments will be acquired with an LSR-II flow cytometer (BD Biosciences), 
with a minimum of 30,000 events per sample.  Detection of tetramer binding by flow 
cytometry will provide a specific signal to allow determination of the frequency of CMV- or 
EBV-specific CD8+ T cells in each sample, as well as the percentage of CMV- or EBV-
specific CD8+ T cells expressing PD-1 within a given sample.  Thus, the planned longitudinal 

 
 
analysis will define the effects of antiviral therapy on CD8+ T cell populations in IPF patients, 
as well as determine the capacity for immunologic biomarkers, such as PD-1, to identify 
response to therapy. 
11.2.2.2. While the studies described above will quantify differences in lymphocyte populations, 
we will also determine differences in lymphocyte activation in response to herpesvirus 
antigens.  For these studies, PBMCs will be stimulated with pooled MHC Class I CMV- or 
EBV- specific peptides followed by flow cytometry with intracellular cytokine staining for IL-6, 
IL-2, and IFN-γ (49).  Results will be reported as the percentage of CD8+ T cells that stain 
positive for each cytokine.  As a positive control, cells will be stimulated with Staphylococcal 
enterotoxin B.  In complementary studies, lymphocytes will be placed in 96-well plates (2x105 
cells/well) and pooled MHC Class I CMV- or EBV- specific peptides will be added to cells in 
triplicate wells for measurement of cytokines, including Th1 cytokine (IL-2, IFN-γ and TNFα), 
Th2 cytokines (IL-4 and IL-10), and IL-6.  Cytokine bead array (CBA) analysis will be 
performed on cell culture supernatants from untreated cells and MHC-I peptide-treated cells 
after 24 hours in culture as previously described.  Together, these studies will determine 
functional differences in CD8+ T lymphocyte populations in response to herpesvirus antigens 
during the course of antiviral therapy.   
11.2.2.3. Similar assays will be performed on lymphocytes isolated from BAL from each patient.  
The typical BAL sample contains 5-10x106 cells, of which 5-10% are lymphocytes.  If cells 
are limiting, then tetramer assays and intracellular cytokine staining will be performed on 
PBMCs only. 
11.3. 
Bronchoscopy:  Individuals in the bronchoscopy substudy will undergo bronchoscopy at study 
entry and at week 12.  Bronchoscopy will be performed using a standard protocol and will include 
airway survey, and BAL.  For BAL, the bronchoscope will be wedged in the lingula or right middle lobe 
and 4 sequential aliquots of sterile saline (60 ml) will be instilled and gently withdrawn. Samples will be 
processed immediately. Bronchoscopy will be performed using standard monitoring procedures 
including continuous cardiac monitoring and blood pressure monitoring and pulse oximetry in the 
bronchoscopy suite at Vanderbilt University Hospital. 
11.4. 
Biologic specimen management:  Following bronchoscopy, BAL fluid will be centrifuged for 
collection of both the cell pellet and the supernatant.  The supernatant will be aliquoted and stored at -
700C.  Total and differential cell counts will be determined and remaining the remaining cell pellet will 
be used for flow cytometry studies.  50 ml of blood will be collected on the day of bronchoscopy, and 
peripheral blood mononuclear cells will be isolated using standard Ficoll-Paque™ density 
centrifugation.  Plasma and serum will be aliquoted and stored at -700. 
 
12. Study drug procedures  
Valganciclovir (Valgan) tablets and placebo will be provided by Genentech, Inc. through the VUMC 
pharmacy. The VUMC Pharmacy Investigational Drug Service (IDS) will dispense study medication at 
baseline and every 4 weeks coinciding with study visits. At the final study visit, subjects will return all 
unused study medication. To maintain blinding, valganciclovir and placebo will be encapsulated by the 
IDS as follows: 
 
Starting Materials: 
1) Valganciclovir 450 mg tablets or placebo 
2) Microcrystalline cellulose 
3) Size “0” orange caps 
4) Capsule machine 
Procedure: 
1) Don appropriate attire for compounding 
2) Fill capsules machine with empty capsules (tops removed) 
3) Place one tablet in each empty capsule 
4) Obtain verification from pharmacist 
5) Cover with microcrystalline cellulose 
6) Replace tops 
7) Clean capsules with capsule cleaning towel 
8) Package and label appropriately 

 
 
9) Log in Investigational Drug Accountability Record 
12.1. 
Contraindications, precautions, and side effects of study medications:  Valganciclovir is FDA 
approved for the treatment and chronic suppression of herpesviruses, and has a good safety profile 
post marketing.  The dose of valganciclovir recommended for this study is well within the FDA 
approved dosing range for other indications.  The major side effect of valganciclovir is bone marrow 
suppression causing anemia, leukopenia, or thrombocytopenia.  GI upset (nausea and diarrhea) is 
another reported side effect. These side effects will be monitored by routine laboratory testing and 
monitoring of subject diaries and direct questioning.  Dose adjustments of valganciclovir are required 
for renal impairment, and dose modifications for renal insufficiency will be made according to 
recommended guidelines based on estimated creatinine clearance using the Cockroft-Gault equation.  
For both valganciclovir and pirfenidone, there are no known major drug interactions requiring special 
clinical monitoring. 
12.2. 
Valganciclovir safety and handling. In animal studies ganciclovir was found to be mutagenic, 
teratogenic, aspermatogenic and carcinogenic. Valganciclovir is considered a potential teratogen and 
carcinogen in humans with the potential to cause birth defects and cancers, and may cause temporary 
or permanent inhibition of spermatogenesis. Women of childbearing age will be required to use a 
medically approved means of contraception and will have urine pregnancy tests performed with each 
study visit. Male patients will be advised to practice barrier contraception during and for at least 90 
days following treatment with valganciclovir.  Tablets will not be broken or crushed. Since 
valganciclovir is considered a potential teratogen and carcinogen in humans, caution will be observed 
in handling broken tablets. Direct contact of broken or crushed tablets with skin or mucous membranes 
will be avoided. If such contact occurs, thorough washing with soap and water, and washing of eyes 
with sterile water will be performed. Unused medication will be returned to the pharmacy for disposal. 
 
13. Data Management and Statistical Analysis Plan 
 
13.1. Data Management: All data for this study will be stored in a password-protected, HIPAA security 
compliant computer database (REDCap). Vanderbilt was a founding member of the secure electronic 
REDCap database and houses much of this database on its servers.  REDCap is a secure, web-based 
application designed to support data capture for research studies and registries. REDCap provides: 1) 
an intuitive interface for validated data entry; 2) audit trails for tracking data manipulation and export 
procedures; 3) automated export procedures for seamless data downloads to common statistical 
packages; and 4) procedures for importing data from external sources.  Only study personnel for this 
project with appropriate permissions will be allowed to access the database. Authorized users can 
input data from anywhere in the world with secure web authentication and data logging. REDCap will 
be used for electronic capture of all data related to study visits with the exception of digital HRCT 
images. Data will be recorded directly from clinical records into REDCap by study personnel trained in 
this protocol.  A second member of the study team will review the data for accuracy prior to the data 
being locked.  This will avoid paper case report forms and any potential for breach of confidentiality 
from maintaining them or transposing data.  All samples obtained for this study will be assigned a code 
which will not identify the subject.  The only key to the code will be in the password-protected computer 
database.  Dr. Blackwell, PI of the study, will be responsible for maintaining confidentiality of data and 
codes. Only Dr. Blackwell and his delegates will have access to the code and information that 
identifies a participant as a being in this study.  The results of analyses run on those samples will not 
be reported to the participant or clinical providers.  No one else, including relatives, doctors, employers 
or insurance companies will be allowed to view the test results.  Informed consent documents will be 
maintained in a locked file cabinet in the study coordinator’s locked office.  Only the study personnel 
will have access to this file cabinet. 
 
13.2. Sample Size and Randomization  
13.2.1. 
Power analysis: This pilot study is designed to determine tolerability and safety of 
valganciclovir as add-on therapy to pirfenidone. Pirfenidone is reported to be discontinued in 
13% of subjects due to adverse events, almost all of which occur within the first 4 weeks of 
treatment (based on AE profiles from the ASCEND study). Therefore, we do not expect any 

 
 
placebo treated subjects to withdraw from this study. Using a 2:1 randomization 
(valganciclovir:placebo) and enrolling 30 subjects will allow us to detect an increased withdrawal 
rate in the valganciclovir group in the range of 25% (75% power with a one-sided a=0.1).  
Subjects who require dose reduction, or temporary discontinuation but are able to resume 
treatment will be considered non-withdrawals. 
13.2.2. 
Randomization: The randomization scheme will be a ratio of 2:1 for drug versus placebo.  
Once a participant has signed the consent form and completed the enrollment visit (and 
baseline bronchoscopy in subjects who participate in the bronchoscopy substudy), the 
participant will be randomized.  Study medication will be distributed by the VUMC investigational 
pharmacy according to the randomization scheme. 
13.3. Statistical analysis:  For the primary endpoint, the rate-of-discontinuation of study drug due to 
adverse events will be compared between valganciclovir and placebo subjects by Chi-square. 
Secondary analysis: Frequencies.of specific adverse event profiles will be compared between groups 
by Chi-square. This study is not powered to detect clinically significant changes in pulmonary function 
or perform multivariate analyses. Exploratory analyses for physiologic and biochemical endpoints will 
be performed using standard nonparametric statistics or paired tests when appropriate. The rate of 
change in FVC (cc/year) will be compared between valganciclovir therapy group (treatment group) 
compared to the standard of care (placebo) group. For other physiologic measurements (6MWD, 
oxygenation), similar analyses will be performed. For exploratory biomarker studies, paired analyses 
(Baseline vs. 12 weeks) will be performed comparing subjects randomized to valganciclovir or placebo. 
All analyses will be performed using STATA 11.0 (StataCorp, College Station, TX) and the 
programming language R (50). 
 
14.  Safety and Adverse Events Monitoring: Study personnel will meet bi-weekly to review all safety 
laboratory data collected on each subject and review all adverse events. The study investigators will decide 
the appropriate steps to be taken to include dose modifications, and further monitoring. Dr. Ciara Shaver 
will act as an on-site medical monitor who can become un-blinded to study drug if needed in order to 
adjudicate side effects are detected and whether they may due to valganciclovir. Planned safety analyses 
will occur after enrollment of 10 and 20 subjects by the medical monitor. If 5 more subjects have withdrawn 
from the study due to adverse events in the valganciclovir arm compared to placebo at either interim 
analysis, the study will be terminated. 
14.1 ASSESSMENT OF SAFETY 
Specification of Safety Variables  
Safety assessments will consist of monitoring and reporting adverse events (AEs) and serious adverse events 
(SAEs) that are considered related to {study drug}, all events of death, and any study specific issue of concern. 
Adverse Events 
An AE is any unfavorable and unintended sign, symptom, or disease temporally associated with the use of an 
investigational medicinal product (IMP) or other protocol-imposed intervention, regardless of attribution. 
 
This includes the following: 
• 
AEs not previously observed in the subject that emerge during the protocol-specified AE reporting period, 
including signs or symptoms associated with idiopathic pulmonary fibrosis that were not present prior to the AE 
reporting period. 
• 
Complications that occur as a result of protocol-mandated interventions (e.g., invasive procedures such as 
cardiac catheterizations). 
 
If applicable, AEs that occur prior to assignment of study treatment associated with medication washout, no 
treatment run-in, or other protocol-mandated intervention. 
 
Preexisting medical conditions (other than the condition being studied) judged by the investigator to have 
worsened in severity or frequency or changed in character during the protocol-specified AE reporting period. 

 
 
Serious Adverse Events 
An AE should be classified as an SAE if the following criteria are met: 
• 
It results in death (i.e., the AE actually causes or leads to death). 
• 
It is life threatening (i.e., the AE, in the view of the investigator, places the subject at immediate risk of death. It 
does not include an AE that, had it occurred in a more severe form, might have caused death.). 
• 
It requires or prolongs inpatient hospitalization. 
• 
It results in persistent or significant disability/incapacity (i.e., the AE results in substantial disruption of the 
subject’s ability to conduct normal life functions). 
• 
It results in a congenital anomaly/birth defect in a neonate/infant born to a mother exposed to the IMP. 
• 
It is considered a significant medical event by the investigator based on medical judgment (e.g., may jeopardize 
the subject or may require medical/surgical intervention to prevent one of the outcomes listed above). 
14.2 METHODS AND TIMING FOR ASSESSING AND RECORDING SAFETY VARIABLES 
The investigator is responsible for ensuring that all AEs and SAEs that are observed or reported during the study, are 
collected and reported to the FDA, appropriate IRB(s), and Genentech, Inc. in accordance with CFR 312.32 (IND 
Safety Reports).  
Adverse Event Reporting Period 
The study period during which all AEs and SAEs must be reported begins after informed consent is obtained and 
initiation of study procedures/treatment and ends 30 days following the last administration of study treatment or study 
discontinuation/termination, whichever is earlier. After this period, investigators should only report SAEs that are 
attributed to prior study treatment. 
Assessment of Adverse Events 
All AEs and SAEs whether volunteered by the subject, discovered by study personnel during questioning, or detected 
through physical examination, laboratory test, or other means will be reported appropriately. Each reported AE or SAE 
will be described by its duration (i.e., start and end dates), regulatory seriousness criteria if applicable, suspected 
relationship to the {study drug} (see following guidance), and actions taken. 
 
To ensure consistency of AE and SAE causality assessments, investigators should apply the following general 
guideline: 
Yes 
There is a plausible temporal relationship between the onset of the AE and administration of the {study drug}, and the 
AE cannot be readily explained by the subject’s clinical state, intercurrent illness, or concomitant therapies; and/or the 
AE follows a known pattern of response to the {study drug}; and/or the AE abates or resolves upon discontinuation of 
the {study drug} or dose reduction and, if applicable, reappears upon re-challenge. 
No 
Evidence exists that the AE has an etiology other than the {study drug} (e.g., preexisting medical condition, underlying 
disease, intercurrent illness, or concomitant medication); and/or the AE has no plausible temporal relationship to 
{study drug} administration (e.g., cancer diagnosed 2 days after first dose of study drug). 
 
Expected adverse events are those adverse events that are listed or characterized in the Package Insert or current 
Investigator Brochure.  
 
Unexpected adverse events are those not listed in the Package Insert (P.I.) or current Investigator Brochure (I.B.) or 
not identified. This includes adverse events for which the specificity or severity is not consistent with the description in 
the P.I. or I.B. For example, under this definition, hepatic necrosis would be unexpected if the P.I. or I.B. only referred 
to elevated hepatic enzymes or hepatitis. 
 

 
 
14.3 PROCEDURES FOR ELICITING, RECORDING, AND REPORTING ADVERSE EVENTS 
Eliciting Adverse Events 
A consistent methodology for eliciting AEs at all subject evaluation timepoints should be adopted. Examples of 
non-directive questions include:  
• 
“How have you felt since your last clinical visit?” 
• 
“Have you had any new or changed health problems since you were last here?”  
Specific Instructions for Recording Adverse Events 
Investigators should use correct medical terminology/concepts when reporting AEs or SAEs. Avoid colloquialisms 
and abbreviations. 
a. 
Diagnosis vs. Signs and Symptoms 
If known at the time of reporting, a diagnosis should be reported rather than individual signs and symptoms (e.g., 
record only liver failure or hepatitis rather than jaundice, asterixis, and elevated transaminases). However, if a 
constellation of signs and/or symptoms cannot be medically characterized as a single diagnosis or syndrome at 
the time of reporting, it is ok to report the information that is currently available. If a diagnosis is subsequently 
established, it should be reported as follow-up information. 
b. 
Deaths 
All deaths that occur during the protocol-specified AE reporting period (see Section 5.1.2), regardless of 
attribution, will be reported to the appropriate parties. When recording a death, the event or condition that caused 
or contributed to the fatal outcome should be reported as the single medical concept. If the cause of death is 
unknown and cannot be ascertained at the time of reporting, report “Unexplained Death”. 
c. 
Preexisting Medical Conditions 
A preexisting medical condition is one that is present at the start of the study. Such conditions should be reported 
as medical and surgical history. A preexisting medical condition should be re-assessed throughout the trial and 
reported as an AE or SAE only if the frequency, severity, or character of the condition worsens during the study. 
When reporting such events, it is important to convey the concept that the preexisting condition has changed by 
including applicable descriptors (e.g., “more frequent headaches”). 
d. 
Hospitalizations for Medical or Surgical Procedures 
Any AE that results in hospitalization or prolonged hospitalization should be documented and reported as an SAE. 
If a subject is hospitalized to undergo a medical or surgical procedure as a result of an AE, the event responsible 
for the procedure, not the procedure itself, should be reported as the SAE. For example, if a subject is 
hospitalized to undergo coronary bypass surgery, record the heart condition that necessitated the bypass as the 
SAE. 
 
Hospitalizations for the following reasons do not require reporting: 
• 
Hospitalization or prolonged hospitalization for diagnostic or elective surgical procedures for preexisting 
conditions 
• 
Hospitalization or prolonged hospitalization required to allow efficacy measurement for the study or 
• 
Hospitalization or prolonged hospitalization for scheduled therapy of the target disease of the study. 
e. 
Pregnancy 
If a female subject becomes pregnant while receiving investigational therapy or within 90 days after the last dose 
of study drug, a report should be completed and expeditiously submitted to the Genentech, Inc. Follow-up to 
obtain the outcome of the pregnancy should also occur. Abortion, whether accidental, therapeutic, or 
spontaneous, should always be classified as serious, and expeditiously reported as an SAE. Similarly, any 
congenital anomaly/birth defect in a child born to a female subject exposed to the {study drug} should be reported 
as an SAE. 
f. 
Post-Study Adverse Events 
The investigator should expeditiously report any SAE occurring after a subject has completed or discontinued 
study participation if attributed to prior {study drug} exposure. If the investigator should become aware of the 
development of cancer or a congenital anomaly in a subsequently conceived offspring of a female subject who 
participated in the study, this should be reported as an SAE.  

 
 
g. 
Reconciliation 
The Sponsor agrees to conduct reconciliation for the product. Genentech and the Sponsor will agree to the 
reconciliation periodicity and format, but agree at minimum to exchange monthly line listings of cases received by 
the other party. If discrepancies are identified, the Sponsor and Genentech will cooperate in resolving the 
discrepancies. The responsible individuals for each party shall handle the matter on a case-by-case basis until 
satisfactory resolution. 
h. AEs of Special Interest (AESIs) 
AEs of Special Interest are defined as a potential safety problem, identified as a result of safety monitoring of the 
Product

• 
Any reports of pregnancy following the start of administration with valganciclovir will be transmitted to 
Genentech within thirty (30) calendar days of the Awareness Date.  
• 
All Non-serious Adverse Events originating from the Study will be forwarded in a quarterly report  Genentech. 
 
Note: Investigators should also report events to their IRB as required. 
MedWatch 3500A Reporting Guidelines 
In addition to completing appropriate patient demographic and suspect medication information, the report should 
include the following information within the Event Description (section 5) of the MedWatch 3500A form: 
• 
Protocol description (and number, if assigned) 
• 
Description of event, severity, treatment, and outcome if known 
• 
Supportive laboratory results and diagnostics 
• 
Investigator’s assessment of the relationship of the adverse event to each investigational product and suspect 
medication 
Follow-up Information 
Additional information may be added to a previously submitted report by any of the following methods: 
• 
Adding to the original MedWatch 3500A report and submitting it as follow-up 
• 
Adding supplemental summary information and submitting it as follow-up with the original MedWatch 3500A 
form  
• 
Summarizing new information and faxing it with a cover letter including patient identifiers (i.e. D.O.B. initial, 
patient number), protocol description and number, if assigned, brief adverse event description, and notation 
that additional or follow-up information is being submitted (The patient identifiers are important so that the 
new information is added to the correct initial report) 
 
Occasionally Genentech may contact the reporter for additional information, clarification, or current status of the 
patient for whom and adverse event was reported. For questions regarding SAE reporting, you may contact the 

 
 
Genentech Drug Safety representative noted above or the MSL assigned to the study. Relevant follow-up information 
should be submitted to Genentech Drug Safety as soon as it becomes available and/or upon request. 
 
MedWatch 3500A (Mandatory Reporting) form is available at 
http://www.fda.gov/AboutFDA/ReportsManualsForms/Forms/default.htm 
 
Additional Reporting Requirements for IND Holders 
For Investigator-Sponsored IND Studies, some additional reporting requirements for the FDA apply in accordance 
with the guidance set forth in 21 CFR § 600.80. 
 
Events meeting the following criteria need to be submitted to the Food and Drug Administration (FDA) as expedited 
IND Safety Reports according to the following guidance and timelines: 
7 Calendar Day Telephone or Fax Report: 
The Investigator is required to notify the FDA of any fatal or life-threatening adverse event that is 
unexpected and assessed by the investigator to be possibly related to the use of valganciclovir. An 
unexpected adverse event is one that is not already described in the valganciclovir Investigator Brochure. 
Such reports are to be telephoned or faxed to the FDA and Genentech within 7 calendar days of first 
learning of the event. 
15 Calendar Day Written Report 
The Investigator is also required to notify the FDA and all participating investigators, in a written IND Safety Report, of 
any serious, unexpected AE that is considered reasonably or possibly related to the use of valganciclovir. An 
unexpected adverse event is one that is not already described in the valganciclovir investigator brochure. 
 
Written IND Safety reports should include an Analysis of Similar Events in accordance with regulation 21 CFR § 
312.32. All safety reports previously filed by the investigator with the IND concerning similar events should be 
analyzed and the significance of the new report in light of the previous, similar reports commented on. 
 
Written IND safety reports with Analysis of Similar Events are to be submitted to the FDA, Genentech, and all 
participating investigators within 15 calendar days of first learning of the event. The FDA prefers these reports on a 
Medwatch 3500 form, but alternative formats are acceptable (e.g., summary letter). 
RANDOMIZATION CODES FOR BLINDED CLINICAL TRIALS 
The blind will be broken for ADR reports that are Serious and Unexpected, unless otherwise agreed with applicable 
regulatory authorities.

15. Recruitment and Informed Consent 
15.1. 
This project will be approved by the VUMC Institutional Review Board (IRB). Participation in this 
study is voluntary. Subjects will be recruited from the Vanderbilt Interstitial Lung disease (ILD) clinic.  A 
number of recruitment strategies to enhance recruitment will be utilized. IRB approved advertisements 
will be posted online through an IRB-approved website post. The Vanderbilt Pulmonary Division has 
extensive physician referral databases that maintain referring physicians located in Kentucky, 
Tennessee, Alabama, Mississippi, Georgia, Arkansas, and Indiana will be mailed information and 
referral brochure. Recruitment and informed consent will not be coercive or unduly influenced by study 
staff. This trial will be registered at Clinicaltrials.gov.  
15.2. 
Written informed consent for participation will be obtained at a face-to-face interview between 
the individual subject and research personnel only after adequate time has been provided for consent 
review and discussion in a private clinic room and prior to any research-related activities.  All questions 
will be answered by study personnel knowledgeable in the protocol.  Subjects are given the 
opportunity and encouraged to take the written informed consent home to review with family and/or 
personal healthcare providers.  Documentation of written informed consent will be made by the 
consenting study staff member placing a note into the electronic medical record.  This note will include 
how consent was obtained, the subject’s level of comprehension, the subject’s decision-making 
capacity at the time of consent, the time given for the subject to consider the research and whether 
others were involved in the decision-making process, and who was present during the consenting 
process. There will be no waivers approved for any portion of the written informed consent, nor will 
surrogate consent be obtained.  All subjects agreeing to this study must be able to understand the 
consent document.  A copy of the signed informed consent will be given to the subject.   
15.3. 
Travel reimbursement. Enrolled subjects will be eligible for reimbursement for travel, meals and 
lodging. Up to $50 per study visit for meals, lodging and mileage (if travel is greater than 50 miles 
roundtrip, reimbursed that the current government rate) will be reimbursed upon provision of travel 
receipts to the study coordinator.  
15.4. 
Compensation. Subjects will not be compensated for study visits. For each bronchoscopy 
completed, subjects will be compensated $200. 
16. Good Clinical Practice 
16.1. 
The procedures set out in this protocol, pertaining to the conduct, evaluation, and 
documentation of this study, are designed to ensure that the investigators abide by Good Clinical 
Practice (GCP) guidelines and under the guiding principles detailed in the Declaration of Helsinki. The 
study will also be carried out in keeping with applicable local law(s) and regulation(s). 
16.2. 
Documented approval from appropriate IEC(s)/IRBs will be obtained for all participating 
centers/countries before start of the study, according to GCP, local laws, regulations and 
organizations. When necessary, an extension, amendment or renewal of the EC/IRB approval must be 

 
 
obtained. Strict adherence to all specifications laid down in this protocol is required for all aspects of 
study conduct; the investigator may not modify or alter the procedures described in this protocol. 
16.3. 
Modifications to the study protocol will not be implemented by the investigator without approval 
of the IRB. However, the investigator may implement a deviation from, or a change of, the protocol to 
eliminate an immediate hazard(s) to the trial patients without prior IEC/IRB/favorable opinion. As soon 
as possible, the implemented deviation or change, the reasons for it, and if appropriate, the proposed 
protocol amendment should be submitted to the IEC/IRB/head of medical institution. Any deviations 
from the protocol must be explained and documented by the investigator.
