PRÉCIS 
Prevention of oral chronic graft versus host disease (GVHD) by topical agents is an attractive strategy because it 
would potentially avoid the adverse effects associated with systemic immunosuppression. Topically administered 
dexamethasone solution is a commonly used agent for the prophylaxis1 of oral inflammatory conditions including 
GVHD. However, the efficacy and systemic effects of topically administered dexamethasone solution are 
unknown. We therefore propose this trial designed to evaluate the efficacy and safety of topical dexamethasone 
solution for prevention of oral chronic GVHD in stem cell transplant recipients.
This pilot phase II study will follow a randomized, double-blind, placebo controlled, parallel group design. 
Consenting subjects who have undergone hematopoietic stem cell transplantation at the NIH Clinical Center and 
the surrounding transplant clinics will be randomized 50/50 to receive dexamethasone 0.01% solution or placebo 
as an oral rinse for 3 months starting 90-100 days post-transplant. Subjects will be evaluated monthly after the 
start of intervention. Diagnostic and research evaluations will include a complete oral examination, oral mucosal 
biopsy prior to the beginning of the intervention (day -7) and at the time of development of oral chronic GVHD or 
at the completion of intervention in the absence of clinical GVHD. We will measure serum dexamethasone levels 
and perform short cosyntropin (ACTH stimulation) test at the end of the 3 months of intervention or onset of 
clinically significant GVHD.
The primary objective of the study is to evaluate the safety and efficacy of topical dexamethasone 0.01% solution 
used as an oral rinse for prevention of oral chronic GVHD. Our primary endpoint will be the proportion of 
subjects that develop clinically significant (severity score 3 or higher) oral chronic GVHD after three months. 
Secondary objectives will include the impact of oral chronic GVHD on the quality of life, characterization of the 
changes in tissue and salivary biomarkers associated with development of oral graft versus host disease, and 
measures of the effects of topical dexamethasone on hypothalamo-pituitary-adrenal axis. Secondary outcomes 
will include oral cavity specific quality of life as measured by OHIP-14 questionnaire, oral discomfort levels, 
improvement in general quality of life scores, and severity of oral chronic GVHD as measured by the site-specific 
GVHD scoring system.
1 The term prophylaxis, preventive treatment and treatment are used interchangeably. Treatment using oral dexamethasone 
will always mean prophylactic treatment.

2. BACKGROUND 
2.1
Graft Versus Host Disease 
In recent years, allogeneic stem cell transplantation has been used increasingly for malignant disorders, 
including solid tumors [1, 2]. GVHD is a major complication and a leading cause of morbidity and mortality 
in recipients of allogeneic stem cell transplantation. GVHD results from immunologic attack by the donor 
immune cells on the tissues and organs of the recipient. Skin, gastrointestinal tract, and liver are the most 
commonly targeted organs. The incidence and severity of GVHD can vary depending on the degree of 
mismatch of major histocompatibility antigens of the donor and host, age of donor and recipient, source of 
stem cells, and the type of the preparative regimen. With development of non-myeloablative conditioning 
regimens, the early post-transplant mortality has dropped with more patients developing GVHD.  Given the 
undersupply of related donors, the use of unrelated and partially matched unrelated donors is likely to expand. 
As our population ages, the use of both older donors and recipients will become more frequent [3]. These 
factors are likely to increase the incidence of GVHD in the coming years. 
Traditionally, GVHD was classified arbitrarily as acute (occurring within 100 days of transplant) and 
chronic (occurring 100 days or more after transplant) [4]. Overall, up to seventy percent of patients who 
survive more than 100 days after transplantation will develop the chronic form of GVHD with the majority 
manifesting in the first year [5-8]. Chronic GVHD has many features of known autoimmune diseases, such 
as lupus, lichen planus, and scleroderma, and can have a varied clinical presentation. Mononuclear cellular 
infiltrates can be found in many areas of the graft recipient, including the liver, skin, oral mucosa, and 
salivary glands. 
In order to provide prognostic and treatment guidelines, chronic GVHD has been classified as limited and 
extensive depending on the number of the organs involved and the severity of the disease [3]. Limited 
chronic GVHD was defined as isolated skin involvement less than 50% with or without liver dysfunction 
and did not require systemic immunosuppression. In contrast, extensive chronic GVHD had evidence of 
skin, mouth, eyes, liver or other target organ involvement. A more recent classification based on several

risk factors appears to better stratify this complex patient population [9]. This complication of transplant 
can persist for months to years, and requires long-term management by multiple disciplines.
2.2
Oral Involvement in Chronic GVHD
Oral chronic GVHD is common and is a major cause of morbidity and loss of quality of life in long-term 
survivors[10, 11]. In a recent randomized trial of peripheral blood stem cell (PBSC) vs. bone marrow stem 
cells (BMSC) transplants, oral mucosal changes were the most common manifestation of chronic GVHD in 
BMSC recipients and the second most common (after skin) in PBSC transplants. Overall incidence was 
around 85% [5]. Oral manifestations of the chronic GVHD include lichenoid changes, mucosal atrophy and 
ulcerations, taste disturbances, and salivary gland hypofunction. Oral pain and food sensitivity are common 
and not limited to patients with ulcerations [12, 13]. Oral discomfort was shown to be associated with 
decrease in food intake and weight loss in this group of subjects [14]. No studies have evaluated the impact 
of oral chronic GVHD on quality of life after stem cell transplantation. 
There have been several reports of increased incidence of oral squamous cell carcinoma (SCCA) after 
hematopoietic stem cell transplantation (HSCT) [15, 16]. Oral chronic GVHD was an independent risk 
factor for SCCA after HSCT. Most of the cases described occurred in patients treated with myeloablative 
conditioning. It is unknown whether early or preventive treatment of oral chronic GVHD can decrease 
incidence of subsequent SCCA. 
The incidence of chronic GVHD in the placebo group was originally estimated as 0.6 based on the 
published literature. The reported incidence varies from 38 to 83% depending on the type of stem cell 
transplantation (as shown in the table below). Peripheral blood stem cell (PBSC) transplantation had a 
higher incidence of chronic oral GVHD compared to bone marrow transplantation. At our institute, we use 
peripheral blood stem cell as a stem cell source. However there are different protocols utilizing T-cell 
depleted peripheral stem cell transplantation which provides similar T cell dose (10-H-0154) or even a 
smaller T cell (06-H-0248, 12-H-0028) dose as the ones used in bone marrow grafts. Furthermore, most 
literature reported the incidence of chronic oral GVHD irrespective of its severity. Busca et al. 
(Haematologica 2005; 90: 567) reported up to 62.5% of chronic oral GVHD were graded as moderate to 
severe (equivalent to grade 3 or higher). Therefore, the incidence of clinically significant (grade 3 or higher) 
oral chronic GVHD at day 90 after randomization, a primary endpoint of this study would be potentially 
around 40%, much lower than 60%.

Currently, all subjects undergoing stem cell transplantation receive some form of acute GVHD prophylaxis 
with systemic immunosuppressive agents, most commonly cyclosporine with methotrexate. The duration of 
this regimen is based on past studies where the majority of severe GVHD occurred in the first 100 days post 
transplant. Therefore, subjects typically are maintained on immunosuppression for the first 100 days which 
in the absence of clinical GVHD is thereafter tapered. Although widely accepted, this arbitrary time point 
for initiation of immunosuppression withdrawal may not be ideal for all subjects as some subjects may 
benefit from earlier withdrawal of immunosuppression to boost the anti-tumor effect of the graft. 
Conversely, subjects with impending GVHD may benefit from longer duration of prophylaxis. 
Attempts to prevent chronic GVHD by systemic immunosuppression have been largely unsuccessful [17, 
18]. There are no human studies to our knowledge that have evaluated the possibility of topical or local 
modalities for chronic GVHD prevention. If proven effective, topical or local therapies could be very useful 
for chronic GVHD prevention given their general lack of systemic side effects. 
2.4
GVHD Therapy
2.4.1
Systemic immunosuppressive agents 
The treatment for GVHD consists of various systemic immunosuppressive agents, most commonly systemic 
corticosteroids, cyclosporine, tacrolimus, mycophenolate, and sirolimus. Long-term immunosuppressive 
treatment for GVHD has a variety of serious side effects including life-threatening infections, aseptic bone 
necrosis, hypertension, and secondary diabetes [3, 19]. 
Systemic corticosteroids 
Corticosteroids are currently the most commonly used systemic treatment of both acute and chronic GVHD. 
Although systemic corticosteroids were ineffective for prevention of GVHD and were associated with an 
increased number of complications like infections and aseptic bone necrosis, the preventive potential of 
topical therapy has not been investigated. Immunosuppressive and anti-inflammatory effects of 
corticosteroids are mediated through many mechanisms, including immune cell apoptosis. Corticosteroids 
have been shown to prevent development of dermal dendritic cells in vitro [20]. Additionally, topical 
corticosteroids induced apoptosis in the murine epidermal Langerhans cells [21]. The critical role of 
dendritic cells in the development of GVHD has been outlined in several studies. One study demonstrated 
the potential of GVHD prevention via depletion of host antigen presenting cells in a murine model [22]. In 
another animal study, local depletion of Langerhans cells in the skin prevented GVHD. 
2.4.2
Topical corticosteroids 
Systemic treatment can be supplemented by topical administration of corticosteroids or tacrolimus.
Dexamethasone is a readily available corticosteroid used topically and systemically in a wide variety of 
conditions. It is the only corticosteroid commercially available in the generic solution form for internal use. 
Dexamethasone does not cross-react in plasma cortisol assay. Dexamethasone solution or elixir is intended 
for systemic use, but is widely used topically by oral medicine practitioners for the treatment of oral 
ulcerative conditions due to convenience of administration and lack of irritation from a vehicle. 
Dexamethasone in the rinse form has been used for the treatment of oral manifestations of GVHD [23]. There 
are few side effects associated with oral topical corticosteroid use, the most common being oral candidiasis. 
Since most patients after stem cell transplantation receive antifungal agents preventively, the incidence of this 
complication is likely to be low. 
Corticosteroids have been shown to possess several properties that make them attractive candidates for 
topical use with the goal of oral GVHD prevention. For example, they interfere with dendritic cell 
maturation, but not migration [24]. Keeping dendritic cells in an immature state could be advantageous in

the peripheral tissues, because the immature dendritic cells have been shown to play a key role in induction 
of tolerance [25]. Dexamethasone has been shown to induce immunosuppressive IL-10 producing dendritic 
cells which may potentially induce tolerance to peripheral tissue antigens [26]. 
2.5
Scientific and Clinical Justification 
Prevention of oral GVHD by topical agents is an attractive strategy because it would potentially avoid the 
adverse effects associated with systemic immunosuppression. Most importantly, using immunosuppressive 
and tolerizing agents locally would concentrate the effects in the area where they are beneficial, as GVHD 
occurs in response to recognition of peripheral antigens by activated donor T-cells. Conversely, use of 
systemic agents for the same purpose would interfere not only with the undesirable GVH response, but also 
with immune responses directed against the malignancy (i.e. the graft vs. tumor effect), which is the 
principal mechanism through which reduced intensity transplants achieve sustained disease remission. 
There are no studies of dexamethasone absorption when used topically in the oral cavity and expectorated. 
The systemic effects of topically administered dexamethasone solution have not been investigated. Since 
this is a commonly used agent for the treatment of oral inflammatory conditions including GVHD, 
knowledge of the degree of systemic action would be valuable. If the absorption is significant, some degree 
of adrenal suppression is likely. This may have implications in many situations when systemic effects of 
steroids are undesirable.
We therefore propose a trial of topical dexamethasone solution for prevention of chronic oral GVHD in 
stem cell transplant recipients ages 12 and older. Additionally, this study will provide valuable insights into 
the cellular and molecular alterations associated with the development of chronic GVHD and treatment with 
topical corticosteroids. This will lead to better understanding of the pathogenesis of chronic GVHD and 
potentially development of new therapeutic interventions.

Subject Registration and Prophylactic Treatment Randomization 
Subjects will be recruited from NIH Clinical Center and the surrounding transplant clinics. After 
confirmation of eligibility and execution of an informed consent,  the Principal Investigator or the research 
nurse will notify the pharmacy of the subject’s enrollment and the pharmacy will randomize the subject to 
therapy. Both investigators and subjects will be blinded to the group assignment until the completion of the 
study. Assignment of treatment will be done using a block randomization scheme with the assignment 
probability remaining fixed over the course of the trial. Construction of the randomization schedule is done 
by pharmacy using a table of random numbers. Subjects will be stratified by the type of conditioning 
(myeloablative vs. non-myeloablative) to ensure comparable groups. 
4.4
Recruitment 
Recruitment activities with surrounding transplant clinics will include electronic physician to physician 
letter distribution, and will include a copy of the recruitment flyer. 
5. TREATMENT PLAN
5.1
Study Drug Administration 
The study drug or placebo will be dispensed to the subject by the NIH Clinical Center Pharmacy according 
to the randomization schedule. Treatment assignment will be unknown to subjects, clinical staff and study 
investigators in order to preserve the blind. Subjects will be instructed to rinse oral cavity 3 times daily for 2 
minutes with 10 mL and expectorate. Subjects will also be instructed to avoid eating, drinking, or rinsing 

07-H-0005

10
the oral cavity for 30 minutes after administration.
5.1.1 Dexamethasone 
Commercially available dexamethasone 0.01% (0.5mg/5 mL) solution will be repackaged, and labeled by 
NIH Clinical Center Pharmacy under USP <795> guidelines and FDA 503a regulations for the purpose of 
this study and to allow blinding to subject, clinical staff, and investigators. The study drug supply will be 
dispensed by the NIH Clinical Center Pharmacy. In case of accidental ingestion, this would be equivalent to 
about 20 mg of prednisone/day if all 3 doses were swallowed. 
5.1.2 Placebo 
The placebo rinse (identical to dexamethasone solution in appearance and taste) will also be compounded, 
labeled, and dispensed by the NIH Clinical Center Pharmacy under USP <795> guidelines and FDA 503a 
regulations. The placebo rinse will be administered in the same fashion as the dexamethasone rinse.
5.2
Permitted Concomitant Medications
5.2.1   Topical antifungals (clotrimazole)
Topical corticosteroid treatment is associated with few potential complications. The most common is candidal 
overgrowth. Subjects will be placed on topical antifungal prophylaxis with clotrimazole 10 mg oral troches 2 
times daily for the duration of the intervention to decrease the candidal overgrowth. In subjects unable to 
tolerate the medication, nystatin swish and spit will be prescribed. 
5.2.2   Post transplant medications
There will be no prohibited interventions for this study except topical agents for oral GVHD. All 
interventions and medications dictated by the subject’s primary transplant protocol and clinical necessity 
will be permitted. Subjects will be queried at interim assessments regarding topical and systemic analgesic 
use. Factors that can potentially confound the results (such as systemic steroids and other 
immunosuppressants) will be tracked and taken into consideration at the time of the final statistical analysis.
5.3
Development of Oral Chronic GVHD
In the event of reaching the primary endpoint (development of clinically significant oral chronic GVHD), the 
subject will be asked to participate in end of study assessments and then will go off study and treatment 
options for treating the oral chronic GVHD will be per the transplant team. 
5.4
Management of Complications
5.41
Oral candidiasis
If oral candidiasis develops despite clotrimazole prophylaxis, standard treatment will be administered. 
5.4.2
Adrenal suppression
Asymptomatic subjects without clinical signs of adrenal insufficiency and abnormal ACTH and/or cortisol 
test results at the end of the intervention period may be observed without steroid replacement and retested in 
1 month. In case of development of symptoms suggestive of adrenal suppression (such as abdominal pain, 
nausea and vomiting, fatigue and hypotension) subjects will then be placed on the standard maintenance 
replacement regimen of the corticosteroids such prednisone 5-7.5 mg once daily and reevaluated in 1 month 

07-H-0005

by ACTH testing. All subjects with the abnormal ACTH test results will be advised of the symptoms and 
signs of clinically significant adrenal suppression and will be given stress doses of hydrocortisone injections 
for emergencies and a wrist bracelet. 
Other complications
Other complications attributable to the medications or procedures used in this study such as allergic 
reactions will be managed in accordance with the currently accepted standards of care.

Clinical Data System (CDS) or the Laboratory of Cardiac Energetics (LCE) database. Primary data obtained 
during the conduct of the protocol will be kept in secure network drives or in approved alternative sites that 
comply with NIH security standards. Primary and final analyzed data will have identifiers so that research 
data can be attributed to an individual human subject participant, e.g., study-specific identifying number 
(SSPIN) generated by CDS or other unique code, or minimum PII required for subject identification.
Study data will be stored on the P drive, the Hematology Branch, secure, limited access drive. 
End of study procedures: Data will be stored in locked cabinets and in a password protected database until 
it is no longer of scientific value. At the completion of the study the data will be analyzed by the study 
statistician.
Loss or destruction of data: Should we become aware that a major breech in our plan to protect subject 
confidentiality and trial data has occurred, the IRB will be notified.
Publication policy: Given the research mandate of the NIH, subject data including the results of testing and 
responses to treatment will be entered into an NIH-authorized and controlled research database. Any future 
research use will occur only after appropriate human subject protection institutional approval such as 
prospective NIH Intramural IRB review and approval or an exemption from the NIH Office of Human 
Subjects Research (OHSR).

permission of the subject, except as necessary for monitoring by the IRB, NHLBI, FDA, or the DSMB. 
6.7.5 Publications and research findings
Publication of the results of this trial will be governed by the policies and procedures of NIH. Any presentation, 
abstract, or manuscript will be made available for review by NHLBI/NCI prior to submission.
7. ANCILLARY EXPLORATORY LABORATORY RESEARCH STUDIES
7.1
Collecting, Tracking and Disposition of Samples
Sample collection:  During the course of participating on this study (screening appointment, follow-up 
visits, end of study visit, and at the time of development of chronic oral chronic GVHD) blood and saliva 
will be collected for correlative laboratory research studies. Oral mucosal tissue collection may be 
performed at baseline, completion of intervention and/or development of oral chronic GVHD, and end of 
study (6 months after completion of the intervention/12 months post-transplant) and will be collected in 
the presence of clinical GVHD. Half of the tissue collected will be sent to the department of pathology for

routine H&E staining and the other half will be snap frozen in liquid nitrogen and stored at -80°C for 
research use.
Intended use: These research specimens will not be read by a pathologist or used for diagnostic 
purposes. Studies will not be used in assessing the primary endpoint, but are undertaken for descriptive or 
exploratory ancillary research.
Storage: Research samples will be stored with identifiers in the secure laboratory of Richard Childs, 
M.D.
Tracking: Samples will be ordered and tracked through the CRIS research screens.  Should a CRIS 
screen not be available, the NIH form 2803-1 will be completed and will accompany the specimen and be 
filed in the medical record. In order to ensure proper tracking across several labs, the progress note 
detailing the consent process will also detail the laboratory to which the sample was initially sent. 
Specimens will be entered in the NHLBI Biospecimen Inventory System (BSI). Samples will not be sent 
outside NIH without IRB notification and an executed MTA. 
End of study procedures: Samples from consenting subjects will be stored until they are no longer of 
scientific value or if a subject withdraws consent for their continued use, at which time they will be 
destroyed. 
Loss or destruction of samples: Should we become aware that a major breech in our plan for tracking 
and storage of samples has occurred, the IRB will be notified.

7.3 Tissue Studies of Pathogenesis of Oral Chronic GVHD 
7.3.1 Immune cell kinetics in the oral tissues 

07-H-0005
Joseph Clara, M.D.
February 3, 2021
Amendment AA

Microscopic examination of the H&E stained tissue sections will be performed in the Laboratory of 
Pathology. Oral chronic GVHD grade will be determined based on the following criteria:
1.
Number/percentage of the dyskeratotic cells
2.
Number/percentage of the intraepithelial lymphocytes
3.
Degree of the basal cell layer destruction
4.
Degree of the subepithelial lymphocytic infiltrate 
Immune cell infiltrate will be characterized by immunohistochemistry and laser scanning cytometry using 
appropriate markers for T-cell subsets (CD3, CD4, CD8), NK cells (CD16, CD56) and dendritic cell subsets 
(CD1a, CD11c, CD123, CD205/DEC-205, CD207/Langerin, CD209/DC-SIGN, BDCA-2, 4). Apoptosis 
will be assessed by immunohistochemical staining of the cells for apoptotic markers (e.g. caspase 3). Laser 
scanning cytometry allows precise quantitative evaluation of different cell populations in the tissue sections 
by analogy with flow-cytometry and has been used successfully to characterize immune cell infiltrates [27]. 
We are particularly interested in the role of peripheral tissue dendritic cells in chronic GVHD. The role of 
dendritic cells in induction of peripheral tolerance has received considerable attention in the recent 
literature. For example, plasmacytoid dendritic cells (pDCs) have been suggested to drive Th2 responses 
and promote induction of T-regulatory cells [28, 29]. The role of plasmacytoid dendritic cells in chronic 
GVHD is unclear. Studies of association of peripheral blood pDCs with cGVHD rendered conflicting 
results [30, 31]. pDCs have been reported to be present in small numbers in the normal skin and increase in 
certain inflammatory conditions [32]. The relative numbers and function of different dendritic cell subsets 
in the tissues in chronic GVHD setting has not been investigated. 
Corticosteroids have been shown to interfere with dendritic cell maturation [24]. Keeping dendritic cells in 
an immature state could be advantageous in the peripheral tissues, because the immature DCs have been 
shown to play a key role in induction of tolerance [25]. Dexamethasone has been shown to induce IL-10 
producing DCs which may potentially induce tolerance to peripheral tissue antigens [26]. 
Additionally, we will assess the degree of chimerism of keratinocytes, antigen-presenting cells and 
lymphocytes in tissue sections. Data from the transplantation literature suggests that transplanted donor 
cells are capable of stable integration into the recipient tissues [33, 34]. Integration of donor cells into the 
peripheral tissues has the potential to affect the antigenic repertoire. It is unclear to what degree such “in-
situ” chimerism could affect the development of tolerance or conversely – graft versus host disease. We 
hypothesize that increased donor chimerism of peripheral tissues could facilitate establishment of tolerance 
to recipient tissue antigens by analogy with organ transplants, where increased population of donor organs 
by recipient cells is thought to be partially responsible for long-term tolerance to transplanted organs. Adult 
mesenchymal stem cells have been demonstrated to migrate to the sites of tissue damage and integrate into 
the tissues [35]. Mesenchymal stem cells have been shown to possess immunomodulating and tolerogenic 
properties and may play a role in tolerance induction in peripheral tissues of the recipient [36] . Although, 
studies have shown that mesenchymal stem cells in the bone marrow of the transplant recipients are of the 
host origin, it is possible that the infused donor mesenchymal stem cells populate peripheral tissues and 
change their phenotype. We plan to investigate three types of cell populations in oral tissues, namely 
keratinocytes, antigen presenting/Langerhans cells, and lymphocytes for degree of chimerism and correlate 
the findings with the clinical and histopathological severity of GVHD. Briefly, tissue sections will be 
stained by immunohistochemistry for appropriate cell markers and the pure cell populations will be 
dissected by laser capture microdissection. After isolation of DNA, we will perform PCR for short tandem 
repeats (STR) of the selected locus and analyze the fluorescent PCR products using capillary sequencer. 
This method has an advantage of high sensitivity and is independent of donor-recipient gender 
mismatch[37].

7.3.2 Gene expression profiles (because oral biopsies are optional, samples will not be available for all 
subjects)
Biopsied oral mucosal tissue will be sectioned and part prepared for the gene array analysis. Six (6) μm 
thick cryostat frozen sections will be prepared and stored at -80oC. Prior to RNA extraction, the 
keratinocyte layer will be separated from the underlying layers by laser capture microdissection. 
Additionally, a 2 mm thick layer of the underlying tissue will also be dissected. This will allow us to take 
into account different tissue thickness in the oral mucosal biopsies and enrich for keratinocytes and immune 
cells. The two layers will be assayed separately. We will use focused, pathway specific arrays (Superarray, 
Superarray Bioscience Corporation, Frederick, MD) for gene array studies. Specifically, arrays focused on 
apoptosis, dendritic cells/antigen presentation, cytokines, and chemokines/adhesion molecules will be used. 
The use of smaller, more focused arrays decreases the statistical problems associated with multiple testing 
and simplifies data analysis. The most interesting and significant findings will be validated by PCR and 
protein based assays, such as immunohistochemistry and ELISA. These samples will not have direct subject 
identifiers.
7.3.3 Histopathologic diagnosis of oral cGVHD 
In the setting of subclinical tissue changes including absence of inflammation or lichenoid hyperkeratosis, 
positive histopathologic findings (lichenoid interface lymphocytes with exocytosis and variable apoptosis), 
have been noted in the baseline oral buccal mucosal biopsies in this study. This phenomenon has been noted 
in the literature [38-40], however, the diagnostic and prognostic value of this finding has not been reported. 
This sub-study will use all available baseline oral biopsies from 07-H-0005 to address this question. 
7.3.3.1 Re-evaluation of the baseline histopathologic findings of patients in protocol 07-H-0005 
Scanned, de-identified images of the H&E slides will be sent to four pathologists with extensive experience 
in evaluating oral GVHD to individually evaluate all baseline oral biopsies from 07-H-0005. No identifiable 
patient or clinical information will be shared with the pathologists beyond the general time post-transplant 
(approximately 90 days) and the reason for the biopsy (protocol baseline). All files will be mailed on a 
compact disc to the individual pathologist, to be viewed using the Aperio digital pathology viewer software 
and scored using a standard matrix (Appendix F).
This data will be collected from the pathologists and will be used to calculate
o
Inter-rater reliability of the pathologists for oral cGVHD diagnosis
o
Incidence of cGVHD diagnostic features in the absence of clinical signs, along with the 
individual histopathologic features most common in the oral mucosa in the early post-
transplant period 
This pathology data will then be combined with clinical data, including pre-transplant conditioning 
regimen, chemotherapy and irradiation history, and any incidence of acute or chronic GVHD to determine 
the clinical significance and the negative and positive predictive value of this histopathologic finding. 
7.4
Salivary and Plasma Proteomics 
We hypothesize differential expression of salivary and plasma proteins before and after GVHD 
development. GVHD specific biomarkers would be potentially useful for predictive and prognostic 
purposes. It may also provide insight into the biology of the disease as manifested in the oral cavity. We 
will also compare the salivary protein expression profiles to those from other autoimmune conditions with 
similar presentation such as Sjogren’s syndrome.

We will use surface enhanced laser desorption/ionization – time of flight (SELDI-TOF) mass spectrometry 
(MS) to investigate screen for differences in protein expression in whole saliva. SELDI-TOF MS Protein 
Chip technology has been used extensively for biomarker mining and proteomic pattern determination on 
various body fluids including plasma, urine, and saliva [41, 42]. It uses various affinity surfaces (protein 
chips) to selectively bind the proteins of interest from the sample. The absorbed proteins are then ionized by 
a laser shot and the resulting ions accelerate over a certain distance in the mass spectrometer. The time of 
flight of each ion can be measured and is inversely proportional to the mass of the protein ion. This 
information in the form of flight times and ion current intensity can be collected, displayed graphically in 
the form of intensity peaks, and later analyzed by bioinformatic software. Expression differences detected 
by this high throughput method can be validated using traditional antibody based assays. 
Additionally, we will use 2-dimensional difference in gel electrophoresis (2D-DIGE) to further evaluate the 
salivary and plasma protein expression before and after development of GVHD. This method is 
complementary to SELDI-TOF in that it has better accuracy for higher molecular weight proteins [43]. 
Differentially expressed protein spots on a gel can be excised and protein identity determined by mass 
spectrometric sequencing. The results of the proteomic studies will be used for hypothesis generation for 
future investigations. 
7.5 Oral Bacterial Colonization 
We will evaluate the oral bacterial flora changes associated with development of chronic GVHD by broad 
range bacterial 16S rDNA PCR. This sensitive methodology allows simultaneous testing of multiple, 
including non-cultivatable, bacterial strains and has been used for microbiological surveillance in various 
mucosal sites [44]. The important role that bacteria play in maintenance of local homeostasis has been 
demonstrated in several conditions in which disease phenotype is associated with profound shift from 
“health-associated” to “disease-associated” flora [45]. The pathogenesis of other conditions, such Crohn’s 
disease has been linked to loss of tolerance to normally harmless commensal bacteria with inappropriate 
inflammatory response [46]. Within the GI tract, dendritic cells constantly sample the antigens from the 
lumen of the gut and present them to naïve T-cells in the Peyer’s patches and mesenteric lymph nodes 
inducing tolerance to commensal bacteria and immune responses to pathogens [47]. It is possible that a 
similar mechanism operates in oral tissues. 
8. BIOSTATISTICAL CONSIDERATIONS
8.1
Hypothesis
8.1.1 Primary hypothesis 
Our primary hypothesis is that dexamethasone oral rinse 0.5 mg/5 ml administered 3 times a day for 2 
minutes will decrease the incidence of clinically significant oral chronic GVHD (primary endpoint) over the 
three month treatment period. 
8.1.2
Secondary hypotheses
Our secondary hypothesis is that the dexamethasone group will have significantly lower oral GVHD scores 
as measured by the GVHD Severity Scale and The Lichen Planus Severity Scale (Appendix B and C). We 
also hypothesize that prophylactic use of topical dexamethasone will improve oral health specific and 
general quality of life (QOL) as measured by the corresponding QOL instruments. 
8.2
Sample Size and Accrual

07-H-0005
Joseph Clara, M.D.
February 3, 2021
Amendment AA
19
Using the current overall proportion of clinically significant oral chronic GVHD of  0.25, we note that with 
36 patients per arm we would have 80% power to detect the same difference of 30% (15% versus 45%) 
when testing the difference of proportions at a significance level of 0.05.  With amendment R (version date 
5-6-2016), we thus propose to reduce the required sample size to 72 subjects. We aim to achieve this new 
accrual goal within two years and we plan to reassess the futility of protocol if we cannot enroll the 
expected number of subject. 
Drop-outs: In order to maintain appropriate statistical power, subjects who prematurely go off study (i.e. 
are non-compliant with study requirements or develop oral GVHD in the period between baseline 
assessments and first dose of study drug) will be replaced. To account for a possible drop-out rate of up to 
10%, up to 82 subjects may be accrued.  Safety data on drop outs will be included in the safety analysis.
8.3
Primary Endpoint
The primary objective of this study is to evaluate the safety and efficacy of topical dexamethasone 0.01% 
solution used as an oral rinse for prevention of oral chronic graft versus host disease. The primary endpoint 
is the proportion of subjects that develop clinically significant (severity score 3 or higher) oral chronic 
GVHD by three months post dexamethaxone administration. For the purposes of this study, oral chronic 
GVHD with the objective score of 3 or higher on a 6-point oral GVHD scale (Appendix C) will be 
considered clinically significant. An intention to treat analysis will be conducted as the primary analysis.
8.4
Secondary Endpoints 
8.4.1  Scale for Oral Pain, xerostomia
Oral discomfort and xerostomia will be measured by 0-10 scale (Appendix A). We will use this scale to 
evaluate changes in oral pain and xerostomia over the course of treatment at end of study. 
8.4.2
GVHD Severity Scale
Few objective scales assessing severity of oral chronic GVHD in a standardized way have been published. 
One of the recently developed systems [48] (Appendix B) has been shown to have good reproducibility and 
assesses the oral cavity by site (e.g. labial mucosa, dorsal tongue, gingiva) and lesion type (lichenoid, 
erythematous, ulcerative). Scoring will be performed by investigators trained in assessment of oral cavity 
lesions. The results will be correlated with scores from the symptom-oriented instruments and the global 
scale. We will also use a simplified 6 point scale developed for oral lichen planus – a condition that closely 
resembles oral GVHD [49] (Appendix C). For the purposes of this study we will consider a grade of 3 or 
higher a clinically significant oral chronic GVHD. 
8.4.3
Patient-assessed Global Scale (perception of changes in oral condition)
We will also assess subjects’ perceptions of the changes in the oral condition on a 5 item scale (Much 
worse, A little worse, same, a little better, much better). The data will be correlated with the results from the 
numerical scoring system to assess internal validity. 
8.4.4
Oral Health Impact Profile–14
Oral Health Impact Profile–14 (OHIP-14, Appendix D) is a 14 item questionnaire developed to assess the 
state of oral health as perceived by a patient [50, 51]. Increased use of patient centered outcome measures 
has been advocated in the recent years. Patient centered outcome measures complement objective measures 

07-H-0005
Joseph Clara, M.D.
February 3, 2021
Amendment AA
20
to provide a more complete picture of the impact of disease and treatment. OHIP-14 has been used in oral 
disease studies including oral lichen planus (a dermatological condition with manifestation similar to 
chronic oral GVHD). It has been shown to have high validity and reliability, and to be sensitive to treatment 
effects. This scale has not been well studied in children; therefore it will be limited to adults. 
8.4.5
Dexamethasone levels 
Systemic absorption of dexamethasone oral solution will be evaluated by measuring plasma dexamethasone 
levels at the 3 month follow-up appointment. Dexamethasone levels will be blinded to the investigators 
until the end of the study. 
8.4.6
Assessment of adrenocortical function (cortisol levels)
Subjects will be evaluated for possible hypothalamic-pituitary axis (HPA) axis suppression with the 
following measures:
1.
Morning cortisol levels will be determined at baseline, monthly follow-ups (done at NIH), and at 
completion of the interventional phase (3 months after the last dose of study medication). The 
results will be blinded to the investigators until the end of the study. At the end of the study, in 
subjects with morning cortisol levels between 19 mcg/dL and 3 mcg/dL no further adrenal 
function testing will be performed. 
2.
In subjects with the symptoms of suspected adrenal insufficiency, a Short Cosynthropin Test 
(SCT) will be performed to determine if the subject has HPA axis suppression. In brief: venous 
blood will be collected before administration of 250 mcg of cosynthropin (synthetic ACTH) 
around 8 AM to 12 noon, and at 30 and 60 minutes after. The expected rise in cortisol levels is to 
at least 18 mcg/dL (24). In cases of minimally abnormal SCT (stimulated cortisol values of 13-17 
mcg/dL), the test will be repeated the next day, as it has been demonstrated that the result is often 
normal with a repeat test. This test has been shown to be sensitive and specific for evaluation of 
subclinical adrenal suppression [52, 53]. In the unlikely event of significant adrenal suppression 
as assessed by repeat ACTH stimulation test, Clinical Center Endocrinology Service will be 
consulted. Pharmacy will be requested to unblind therapy to the endocrinologist so that 
appropriate therapy can be initiated and the endocrinologist can appropriately attribute the 
relationship of the event to study drug administration. 
3.
The confounding effect of systemic corticosteroids will be taken into account at the time of 
analysis. We expect to have a subgroup of subjects who will not receive systemic steroids. This 
subgroup will be used to evaluate the effects of topical dexamethasone on adrenal secretion. 
8.5
Data Analyses
This study will be analyzed according to the “intent to treat” principle, that is, all randomized subjects will 
be included. Subjects not evaluated for endpoints will be considered to have reached the primary endpoint. 
Every effort will be made to reach and evaluate the subjects at the monthly intervals and at the end of the 3 
month intervention period. The differences in proportions of significant oral chronic GVHD will be 
assessed by a chi-squared test (with continuity correction). Treatment group differences in the severity 
scores, pain and xerostomia scores, and quality of life scores (OHIP-14) will be assessed using the 
Wilcoxon test. Adjustments will be made for age and other covariates of interest, such as systemic 
immunosuppression. Adverse events will be tabulated by severity and treatment assignment. For pediatric 
subjects, analyses will include growth assessment (growth chart [length for age, weight for age percentiles 

07-H-0005

Amendment AA
21
and body mass index] for age percentiles) and bone age and the associated z-scores (the number of standard 
deviations the child’s measures [weight, height etc] differ from the population mean). 
The intervention period will be 3 months. Should the subject reach the primary endpoint (development of 
clinically significant oral chronic GVHD), the subject will be asked to participate in end of study 
assessments and then will go off study. Subjects who did not develop oral chronic GVHD in the 
intervention phase of the study will be followed for up to 6 months to document late development of oral 
chronic GVHD. All subjects will be evaluated after 6 months after completion of the intervention phase of 
the study in the absence of clinical oral GVHD. Final statistical analysis will be performed once all subjects 
in the sample have completed the study and all records have been collected. We will use stratified analyses 
to account for effects of systemic immunosuppressive agents and other prognostic factors. 
In the event of a protocol violation, the aggregate data will be analyzed with and without those subjects 
involved in the incident.
8.6
Interim Analysis
There will be no interim analysis due to the short and preliminary nature of this study.   
8.7
Stopping Rule
There will be no interim statistical analysis given the small preliminary nature of the study. We do not 
expect dramatic efficacy or significant difference in serious adverse effects that would require stopping the 
trial early. The study medication is a safe and non-toxic agent commonly used for the prophylaxis of oral 
chronic GVHD and other oral mucosal conditions. All the procedures specifically related to this protocol 
are standard diagnostic procedures and are associated with few complications. In the event of a serious 
adverse event related to the study medication or procedure the IRB will be notified immediately. 
8.8   Off Study Criteria
8.8.1 Subject choice: 
Subjects may withdraw from the study at their request any time. The risks of withdrawing will be 
discussed, as will alternative treatment options. Those subjects who choose to withdraw will be strongly 
encouraged to participate in post therapy assessments until he/she initiates alternative chronic GVHD 
therapy or through the 6 month off study medication mark to assess for late occurring adverse events. 
8.8.2 Principal investigator decision: 
Subjects will be taken off study during the 3 month study drug administration period:

if they develop oral chronic GVHD in the period between baseline assessments and first dose of 
study drug (subjects will be reassessed between post-transplant days 90 and 100 to ensure absence 
of oral chronic GVHD and reinforce protocol procedures)
if they are unable to comply with the study visits or become severely ill and cannot comply with the 
intervention 
if they reach the primary endpoint of clinically significant oral chronic GVHD
if they have relapse of their underlying disease (leukemia subjects, see section 10.3.1 risk of tumor 
lysis)

DATA AND SAFETY MONITORING PLAN
9.1
Safety Monitoring
Principal Investigator: Accrual, efficacy and safety data will be monitored by Joseph Clara, M.D., the 
Principal Investigator.
NIH Intramural IRB. Prior to implementation of this study, the protocol and the proposed subject 
consent and assent forms will be reviewed and approved by the properly constituted Institutional Review 
Board (IRB) operating according to Title 45 CFR 46. This committee will also approve all amendments to 
the protocol or informed consent, and conduct continuing annual review so long as the protocol is open to 
accrual or follow up of subjects, or data analysis continues. 
NHLBI DSMB: The NHLBI Data Safety and Monitoring Board will review the protocol at an interval to 
be determined by the DSMB. A progress report will be forwarded to the DSMB at these times and their 
recommendations will be expeditiously implemented. The DSMB may recommend early termination of 
the study for considerations of safety and efficacy. 
9.2
Adverse Events 
Because dexamethasone is an FDA approved drug with known toxicity profile, any observed or volunteered 
adverse events will not be captured in the database unless (1) the adverse event is previously unknown (not 
on the label) or more severe than on the label and deemed possibly, probably or definitely related to the 
study medication or (2) meets the criteria for a severe adverse event. Adverse events that are complications 
of the primary transplant protocol and deemed unlikely or unrelated to dexamethosone will not be captured 
in the database for this protocol, but will be collected and reported in the transplant protocol. The collection 
of AE information will begin on the first day of initiation of the study drug. 
The NCI Common Terminology Criteria for Adverse Events Version 4 (CTCAE) will be used for toxicity 
and adverse event reporting.  All appropriate treatment areas have access to a copy of the CTCAE version 
4.0. A copy of the CTCAE version 4.0 can be downloaded from the CTEP web site (http://ctep.cancer.gov).
Adverse event is defined according to 21 (CFR 312.32(a)) as any untoward medical occurrence associated 
with the use of a drug in humans, whether or not considered drug related. An adverse event can also be any 
unfavorable and unintended diagnosis, symptom, sign (including an abnormal laboratory finding), 
syndrome, or disease temporally associated with the use of a drug, without any judgment about causality. 
Adverse event either occurs during the study participation, having been absent at baseline or if present at 
baseline, appears to worsen.

10. HUMAN SUBJECT PROTECTIONS
10.1 Rationale for Subject Selection
No subjects will be excluded from participation based on gender, race or ethnicity. The study will be open 
to all subjects who satisfy the inclusion criteria and provide an informed consent to the protocol. From 
previous transplant protocol recruitment patterns at NIH we expect the population may be distributed as 
follows: 

by gender: 40% females; 60% males

by age: ages 11-73, median 38;  7% ages 10-17; 20% ages 18-30; 28% ages 31-40; 22% ages 41-
50 and 23% ages 51-73

by race/ethnicity: 11% Asian, 8% Black, 44% Hispanic, 37% White
Recruitment: Subjects will be recruited from NIH Clinical Center and the surrounding hematopoietic stem 
cell transplant clinics.
Reimbursement for protocol participation, travel, food, and lodging: Reimbursement will occur on this 
protocol; subject reimbursement will be according to the NHLBI travel policy reimbursement and will be 
consistent with NIH and NHLBI guidelines. 
10.2 Participation of Children  
When a pediatric subject reaches age 18, continued participation will require consenting of the now adult 
with the standard protocol consent document to ensure legally effective informed consent has been obtained. 
Should sample or data analysis continue following completion of active participation and the subject has 
reached 18 years of age, we will attempt to contact the subject using the last known contact information to 
obtain consent for continued use of data or samples collected during their prior visit. Given the length of 

07-H-0005

February 3, 2021
Amendment AA
25
time that may have transpired for some of the subjects since their last visit for this study, we request waiver 
of informed consent for those individuals who after good faith efforts to contact them, we are unable to 
contact.
Requirements for Waiver of Consent consistent with 45 CFR 46.116 (d), each of which must be addressed 
in relation to the protocol:
(1) The research involves no more than minimal risk to the subjects;
a)
Analysis of samples and data from this study involves no additional risks to subjects.
(2) The waiver or alteration will not adversely affect the rights and welfare of the subjects;
a)
Samples and data will be kept in secure locations in the laboratory of Dr. Young. Retention of 
samples or data does not affect the welfare of subjects.
(3) The research could not practicably be carried out without the waiver or alteration; and
a)
Considering the length of time between a minor’s enrollment and their age of majority, it is 
possible that more than a few subjects may be lost to follow up. A significant reduction in the 
number of samples analyzed could impact the quality of the research.
(4) Whenever appropriate, the subjects will be provided with additional pertinent information after 
participation.
a) We only plan to request a waiver of re-consent for those subjects who have been lost to follow-
up.
If the subject is an affected minor (level of risk is Category 3), both parents must provide parental permission 
unless one parent is deceased, unknown, incompetent, or not reasonably available (i.e., incarcerated), or when 
only one parent or guardian has legal responsibility for the care and custody of the child. In the event that 
one parent is not present to provide consent, telephone consent from one parent may be obtained.
If the subject is an unaffected minor (level of risk is Category 1) we request that only one parent be required 
to provide parental permission. However, in cases where parents share joint legal custody for medical 
decisions for a child (e.g., by custody agreement or court order), both parents must give their permission 
regardless of the level of risk of the research.  Exceptions may be made if one parent has since died, become 
incompetent, or is not reasonably available (e.g., incarcerated).
This study will be limited to subjects aged 12 or older. Given the preliminary nature of the study and 
requirement for precise compliance with the instructions to minimize swallowing and systemic absorption 
of dexamethasone, children < 12 who are less likely to comply will be excluded.  In addition, oral rinses 
such as topical fluorides are not recommended for young children; and children < 12 are less likely to 
develop GVHD. Oral biopsy for research purposes will be limited to subjects 18 years old and older.
Pregnancy testing will be done in all females of childbearing potential. We will inform any applicable 
minors during the assent process that for safety, we need to do a pregnancy test. She will be told that if the 
pregnancy test is positive, we will counsel her and help her tell her parents if she wishes. If the minor does 
not want to proceed, she will be advised not to sign the assent and her study participation will end.
10.3 Risks and Discomforts
10.3.1 Related to dexamethasone 
The side-effects of topical steroids are usually limited to Candida (yeast) infection. This is relatively 
uncommon in our subject population (<5%), easily treatable and does not require discontinuation of the 
prophylaxis. 

07-H-0005
Joseph Clara, M.D.

Amendment AA
26
Low levels of topical steroids are absorbed through the oral mucosa, but the exact rate is not known.  
Possible risks associated with absorbed drug include: 

Adrenal suppression: While adrenal suppression is very rare with topically applied corticosteroids, it 
is physiologically possible. Cases of adrenal suppression following topically-applied steroid creams 
have been reported with long-term use on extensive body surface primarily in young children. In 
other reports, it was difficult to determine if there was true adrenal suppression. Symptoms of adrenal 
suppression are non-specific and include fatigue, nausea and abdominal discomfort. Since these 
symptoms are extremely common in the general hospital population, routine monitoring in the 
context of this study is not indicated. In this study, blood pressure will be monitored at every visit, 
and adrenal function will be assessed at the end of prophylaxis. Given the very short duration of this 
study, we do not expect significant side effects. 
In the unlikely event of significant adrenal suppression as assessed by repeat ACTH stimulation test, 
Clinical Center Endocrinology Service will be consulted (see section 8.4.6, Assessment of 
Adrenocortical Function [Cortisol] levels). 

Growth and bone health: Impairment of childhood growth with an approximate cortisone dose of 1.5 
mg/kg/day was first described over 40 years ago; osteopenia in children receiving a prednisolone dose 
of less than 0.16 mg/kg/day has also been reported.52, 53 Loss of bone and deterioration in short term 
growth are dependent on the type and dose of glucocorticoid and occur most prominently over the first 
six months of treatment. 54-56 
We will monitor pre-pubertal pediatric subjects by use of growth chart (length for age, weight for age 
percentiles and body mass index for age percentiles) and bone age (hand x-ray) if the results are 
available on the parent transplant protocol. 

Acute tumor lysis: Two cases of acute tumor lysis syndrome in patients with acute leukemia have been 
reported in the literature following dexamethasone for prophylaxis of peri-operative nausea and 
vomiting; one of which was fatal (patient had a new onset of undiagnosed acute leukemia)[57, 58]. 
Although the dexamethasone on this study is administered as an oral rinse (not swallowed), low levels 
(exact rate unknown) of topical steroids are absorbed through the oral mucosa. Although it is very 
unlikely that acute tumor lysis would occur in our study, in the event of disease relapse in leukemia 
subjects, the study drug will be stopped, and the subject will go off-study (see section 8.8.2)
10.3.2 Related to clotrimazole 
Side-effects associated with clotrimazole troches are rare and may include nausea, vomiting, unpleasant 
mouth sensations, and pruritus. 
10.3.3 Related to blood collection 
Minor complications including bleeding, pain, and hematoma formation at the site of blood draws or 
infections may rarely occur. 
10.3.4  Related to tissue biopsy
Oral mucosal punch biopsy is a minor surgical procedure that may be associated with temporary bleeding, 
hematoma at the site, local infection and postoperative discomfort. These risks are small (generally <5%) 
and transient.

27
10.3.5 Related to pregnancy and nursing mothers 
Although dexamethasone will be applied topically to the oral cavity in this study, some amount of 
medication may be absorbed into the bloodstream. Strong corticosteroids have caused birth defects in 
animals. It is not known whether topical steroids are absorbed in sufficient amounts to appear in breast 
milk. Therefore, pregnant and nursing women will not be eligible to participate in this study. Women of 
childbearing potential will be required to use an effective method of contraception. 
10.3.6 Related to saliva collection
Subjects who have undergone transplant may have decreased salivary function and find it difficult to 
produce a saliva sample. A mild citric acid solution will be placed on the tongue to elicit salivation, and the 
saliva will be collected using mild suction. Subjects might experience a sour taste and mild discomfort from 
the citric acid and oral suctioning.
10.3.7 Related to quality of life assessments
There are little to no risks involved in completing the quality of life assessment measures.
10.4 Risks in Relation to Benefits 
10.4.1  For adult subjects
The risks of participating in this trial are limited to side effects of dexamethasone and clotrimazole, the risks 
of standard diagnostic procedures (oral mucosal biopsy), the collection of saliva, the completion of quality 
of life assessments and an additional blood sample to be used strictly for research purposes. Samples for 
clinical monitoring will be collected during sample collection procedures that are part of their routine post 
transplant care. 
The benefits to the subjects could be prevention of oral chronic GVHD resulting in improved quality of life, 
decreased morbidity associated with oral chronic GVHD (should it develop), and potentially, treatment with 
other more toxic therapies could also be avoided or postponed. Subjects will also receive direct health 
benefits due to thorough post transplant oral examinations, early diagnosis of oral chronic GVHD, and 
therefore earlier access to oral chronic GVHD management. 
10.4.2 For pediatric subjects
The inclusion of children satisfies the criteria set forth in 45 Code of Federal Regulations 46, Subpart D: as 
follows:
(a) “The risk represents a minor increase over minimal risk”. The risks of participating in this trial are 
limited to side effects of dexamethasone and the collection of saliva. Samples for clinical monitoring will be 
collected during sample collection procedures that are part of their routine post transplant care. Only those 
laboratory tests approved by the IRB and involving not greater than minimal risk will be conducted. 
Research will not include genetic testing. Therefore, there is no genetic testing associated risk. 
(b) The relation of the anticipated benefit to the risk is at least as favorable to the subjects as that presented 
by available alternative approaches. Post transplant subjects who co-enroll in this protocol are familiar with 
blood collection and hospital procedures due to their frequent need for monitoring for their primary disease 
and for post transplant care. The monitoring that will be done is with the monitoring for the primary 
transplant protocol. It only minimally exceeds what would be done post transplant (increased oral 
surveillance and saliva samples)

(c) Adequate provisions are made for soliciting the assent of the children and permission of their parents or 
guardians, as set forth in 46.408. An assent form is available.
10.5 Informed Consent 
The investigational nature and research objectives of this trial, the procedure and its attendant risks and 
discomforts will be carefully explained to the subject. The potential subject will be educated regarding the 
nature of the condition, proposed intervention, and outcome measures. Study subjects will be informed that 
participation is entirely voluntary and that withdrawal from the study can be made at any time without 
penalty of benefits to which they may be entitled.
At any time during participation in the protocol that new information becomes available relating to risks, 
adverse events, or toxicities, this information will be provided orally or in writing to all enrolled or 
prospective subject participants. Documentation will be provided to the IRB and if necessary the informed 
consent amended to reflect relevant information.
We anticipate the enrollment of non-English speaking research participants into our study. The IRB 
approved full consent document will be translated into that language in accordance with the Clinical MAS 
Policy M77-2. If there is an unexpected enrollment of a research participant for which there is no translated 
extant IRB approved consent document, the principal investigator and or those authorized to obtain 
informed consent will use a short form oral consent process as described in MAS Policy M77-2, 45CFR 
46.117(b)(2), 21CFR50.27. The summary that will be used is the English version of the extant IRB 
approved consent document.
We request prospective IRB approval of the use of the short form for up to 3 participants in a given 
language and will notify the IRB at the time of continuing review of the frequency of the use of the short 
form. Should we reach a threshold of 3, we will notify the IRB of the need for an additional usage of the 
short form and that we will have that consent document translated into the given inherent language.
10.6   Compensation 
Compensation will be provided for those subjects participating in the study based on the below values 
consistent with NIH and NHLBI guidelines. Subject who are ineligible or choose not to have the procedure 
will receive only partial payment.

APPENDIX B : GVHD SEVERITY SCALE
GVHD Severity Scale (adapted from Piboonniyom S et al, 2005)
The severity of the lesions in each site was scored according to the presence of reticular/hyperkeratotic, 
erosive/erythematous, and/or ulcerative lesion(s) as follows: reticular/hyperkeratotic lesions were scored from 0 to 
1 (0 = no white striations, 1 = presence of white striations or keratotic papules); erosive/erythematous areas were 
scored from 0 to 3 by area of involvement (0 = no lesion, 1 = lesions less than 1 cm2, 2 = lesions from 1 to 3 cm2, 
3 = lesions greater than 3 cm2); ulcerative areas were scored from 0 to 3 by area of involvement (0 = no lesion, 
1 = lesions less than 1 cm2, 2 = lesions from 1 to 3 cm2, 3 = lesions greater than 3 cm2).

For each of the 3 clinical signs, a score was derived by summation of the scores of all 10 areas: reticular 
score = ΣR, erythema score = ΣE, and ulcerative score = ΣU (REU score) with a total weighted score of ΣR + Σ(E 
× 1.5) + Σ(U × 2.0).
