I. BACKGROUND AND SCIENTIFIC RATIONALE 
Chronic graft vs. host disease (chronic GVHD) 
Chronic graft-versus-host disease (chronic GVHD) is a major late complication of 
allogeneic hematopoietic cell transplantation (HCT), which affects up to 70% of HCT 
recipients. The syndrome is associated with major transplant-related morbidity, 
mortality, infectious complications, prolonged duration of immune suppression, and 
impaired patient-reported quality of life.1-8  Thus, it represents a major obstacle to 
recovery and survival following HCT, and its prevention and therapy are of significant 
importance.  
The syndrome is characterized by diverse clinical manifestations, but the most 
commonly affected organs are the skin, eyes, mouth, and liver. However, most organs 
can be involved, with parallels to other systemic immune-mediated disorders, such as 
systemic lupus erythematosis, Sjogren’s disease, and systemic sclerosis.  Clinical 
predictors for the development of chronic GVHD reported in published literature most 
consistently include increasing age of the donor or recipient, donor/recipient HLA 
disparity and donor relation (greater risk in unrelated vs. matched sibling donors), male 
recipients of allografts from alloimmunized female donors, prior development of acute 
GVHD, and the use of peripheral blood mobilized stem cells vs. bone marrow. 9-12  
 
Chronic GVHD diagnosis and classification 
Diagnosis and classification of the syndrome has undergone major revision following 
the 2005 NIH Consensus Conference on Chronic GVHD.  According to the historical 
classification, acute and chronic GVHD were distinguished by the occurrence of 
manifestations before or following day 100 post-HCT. The previously accepted severity 
classification defined limited involvement as restricted to limited cutaneous involvement 
and/or hepatic dysfunction, while extensive disease denoted more substantial 
manifestations such as generalized cutaneous involvement, hepatic dysfunction with 
biopsy confirmation of chronic aggressive hepatitis, bridging necrosis or cirrhosis, or 
involvement of other target organs, such as the eye, mouth, or lung.13   
According to the proposed NIH Consensus definitions, chronic GVHD is rather 
diagnosed according to diagnostic manifestations of the syndrome, rather than the time 
of onset following HCT. Accordingly, manifestations of acute GVHD occurring before 
day 100 are defined as acute GVHD, while those occurring after day 100 are 
considered persistent, recurrent, or late acute GVHD based on the prior occurrence of 
acute GVHD in the patient. Classic chronic GVHD is defined based on the definitive 
manifestations of the syndrome in the absence of concurrent acute GVHD 
manifestations. The concurrent presentation of both operationally defines the overlap 
subtype of chronic GVHD. In addition, guidelines for severity grading were proposed to 
replace the previously accepted scheme based on limited vs. extensive involvement. 
Rather, severity is scored according to objective criteria for each organ involved, which 
is summarized for an overall severity score of mild, moderate or severe.14

Therapy of established chronic GVHD 
Accepted standard primary therapy for chronic GVHD includes 1mg/kg or greater of 
prednisone or equivalent with or without a calcineurin inhibitor.2,15 The addition of other 
systemic immune suppressive agents has not provided benefit, as evidenced by trials 
employing azothioprine, thalidomide, or hydroxychloroquine combined with steroids,16-18 
or the more recent trial evaluating the combination of steroids and mycophenolate 
mofetil.19  However, further work remains to improve the success of primary therapy for 
chronic GVHD, as response is often incomplete.  
In the analysis of major published primary chronic GVHD therapy trials,15-20 the following 
summarizes current evidence: Complete response rate assessed at 6-9 months 
following steroid based therapy (either 1mg/kg of prednisone alone or this in 
combination with additional agents such as azathioprine, thalidomide, 
hydroxychloroquine or mycophenolate mofetil) includes a range of reported values from 
16% to 37%. In the study by Sullivan, et al, 9 month complete response rate to 
prednisone was 33%, prednisone + azathioprine 37%, and prednisone alone among 
high risk cases 16%.16 Arora, et al reported 6 month complete response rate of 17% in 
prednisone + thalidomide and cyclosporine, and 28% for prednisone and cyclosporine 
alone.17 In a more recent trial comparing activity of prednisone vs. prednisone and 
mycophenolate mofetil, Martin, et al reported a 6 month complete response rate of only 
23%.19 Finally, Gilman, et al reported CR rates at 9 months of 38% and 33%, 
respectively for hydroxychloroquine + prednisone vs. prednisone alone. Thus, available 
randomized trials suggest an average complete response rate at 6-9 months of 27%. 
Overall response rate (ORR) (total of complete response (CR) + partial response (PR)) 
has been reported as the following: Sullivan, et al reported ORR of 62% among 
prednisone treated patients, 64% for prednisone with azathioprine, and only 32% for 
prednisone treated patients with thrombocytopenia.16 Arora, et al reported ORR of 84% 
at 6 months for prednisone treated patients and 88% for those treated with prednisone 
and thalidomide.17 Martin, et al reported an ORR of 62% at 6 months for patients treated 
with prednisone + mycophenolate mofetil or prednisone + placebo.19,21 Gilman, et al 
reported ORR at 9 months of 39% and 46% for hydroxychloroquine + prednisone vs. 
prednisone alone.18 Thus, published randomized trials support an average ORR at 6-9 
months of 60%. Importantly, Martin, et al demonstrated that ORR at 6 months of 
therapy was significantly associated with the ultimate risk for treatment failure, defined 
as initiation of secondary systemic GVHD treatment, non-relapse death, or development 
of Bronchiolitis Obliterans. The cumulative incidence of treatment failure was 37% vs. 
63% in those with overall response vs. not, p = 0.01.21   
Based on limited response to primary therapy, many will go on to require additional 
immune suppressive agents for chronic GVHD control. Steroid-refractory chronic GVHD 
has most commonly been defined as either progressive manifestations despite one 
month, or rather incomplete response despite two months of 1-2mg/kg of prednisone or 
equivalent.2 Multiple immune suppressive agents, including pharmacologic agents, 
monoclonal antibodies, and strategies such as extracorporeal photopheresis have 
demonstrated moderate activity in this setting, both ameliorating objective chronic 
GVHD manifestations, as well as importantly facilitating liberation from systemic 
steroids. Their activity is incomplete, however, and many with steroid-refractory chronic 
GVHD will require multiple agents to achieve disease control. The overall burden of 
chronic GVHD despite routine pharmacologic GVHD prophylaxis, limited response to

primary and salvage therapy, and the attendant morbidity and mortality all speak to the 
rationale for novel approaches to primary therapy. 
 
Assessment of therapeutic response in chronic GVHD 
The established method for response determination in the majority of chronic GVHD 
therapy trials is that of clinician-determined response. This method relies on the treating 
clinician’s integration of dynamic chronic GVHD manifestations for a summary response 
categorization of complete response (CR), partial response (PR), stable disease (SD), 
or progressive disease (PD). CR indicates complete resolution of all chronic GVHD 
manifestations; PR signifies reduction in disease activity at response assessment 
compared to pre-treatment levels, but without complete resolution; SD indicates no 
response and no progression; and PD indicates progressive chronic GVHD 
manifestations from baseline to response assessment. This response assessment tool 
will be utilized for the primary endpoint of 6 month ORR in this trial, and for the purpose 
of power/sample size estimation with reference to historical published data on 6 month 
ORR according to this metric. 
Following a 2005 NIH Consensus Conference for Chronic GVHD, several additional 
means of response assessment in chronic GVHD therapeutic trials have been 
proposed. These include change in overall NIH severity categories, proposed NIH 
response criteria, 0-4 and 0-10 ordinal scales that rely on clinician assessment, organ-
specific tools such as the Vienna skin scale, as well as patient-determined change in 
chronic GVHD activity, chronic GVHD associated symptom burden, functional 
limitations, and change in quality of life. A national Chronic GVHD Consortium is 
currently assessing these competing measures of disease activity and their relationship 
to longer-reaching outcomes indicating clinical benefit, such as failure-free survival, 
discontinuation of all immune suppression, overall survival, or patient-reported benefit. 
However, to date these remain proposed tools that lack validation for the purpose of 
chronic GVHD clinical trial design and response determination. 
Accordingly, clinician-determined response (CR, PR, SD, PD) remains the standard for 
the primary measure of therapeutic response in clinical trials. However, comprehensive 
information needed to calculate response according to proposed metrics will be 
collected (see appendix C) during the trial. We will report these data as secondary 
measures of response, and will study both the level of agreement between these 
competing response measures and their association with long-term measures of chronic 
GVHD treatment success. 
  
Clinical Insights into chronic GVHD pathogenesis 
While major insights have resulted from investigation into pathobiology of acute GVHD, 
our understanding of the mechanisms underlying chronic GVHD development and 
maintenance is limited. Murine and human clinical data suggest a clear role for donor 
alloreactive T cells in chronic GVHD pathogenesis: Peripheral blood mobilized stem cell 
products, which contain a greater dose of donor T cells compared to bone marrow 
harvested stem cells, impose a greater risk for the occurrence and severity of chronic 
GVHD and an associated prolonged duration of immune suppression.9 Conversely, ex-

vivo T cell depletion strategies, as well as in vivo strategies such as anti-thymocyte 
globulin (ATG) or alemtuzumab,22-24 are associated with decreased risk of chronic 
GVHD. Basic and human correlative studies also suggest a relationship between 
regulatory T cells and chronic GVHD.25  Allied clinical and basic data, however, suggest 
other important mechanisms. 
Major clinical observations support the role of loss of B-cell tolerance and altered B cell 
homeostasis following transplantation in chronic GVHD pathogenesis: First, 
autoantibodies are often detected in patients with chronic GVHD.26-28 As well, reduced 
levels of immature B cells in patients with chronic GVHD support altered B cell 
homeostasis.29 After sex mismatched HCT, allo-antibodies directed against the Y 
chromosome associated minor histocompatibility antigens, or H-Y antibodies, have 
been detected 4-9 months after HCT and correlate with the occurrence of chronic 
GVHD.30,31 These humoral immune responses were associated with coordinated T cell 
response to HY minor histocompatibility antigen epitopes.32 In the setting of cutaneous 
sclerosis of chronic GVHD, activating anti-PDGFR antibodies have been detected,27 
and agents with activity against this receptor kinase such as imatinib have 
demonstrated activity in this condition.33 Additionally, multiple clinical trials have 
demonstrated activity of the anti-CD20 monoclonal antibody, Rituximab, in the treatment 
of chronic GVHD which has failed standard glucocorticoid therapy.34-36 Finally, HCT 
patients treated preemptively with Rituximab appeared to have less risk for steroid-
requiring chronic GVHD compared to historical controls that did not receive prophylactic 
Rituximab.  
 
Altered B cell homeostasis and excess BAFF in chronic GVHD development  
In a minor histocompatibility-mismatched murine model of chronic GVHD, donor B cells 
were required for the development of chronic GVHD.37 Following transplant 
conditioning, recipient B cells are depleted, and donor B cells demonstrate altered 
reconstitution. Pre-clinical models demonstrate that B cell–activating factor (BAFF) has 
a key role in B cell reconstitution and homeostasis. In such models, B cell survival is 
dependent on B cell receptor and BAFF signaling, and B cell homeostasis is dependent 
on soluble BAFF concentration. BAFF levels, as well as the balance of autoreactive B 
cells and competing naïve B cells determine the fate of autoreactive B cells.38,39 
Importantly, investigators have similarly demonstrated aberrant B cell homeostasis and 
elevated BAFF levels in human HCT recipients who developed chronic GVHD. 
Sarantopoulos, et al performed phenotypic and functional studies of peripheral blood B 
cells in 82 patients following HCT.40 These included ‘group 1’ of 57 patients (22 with 
active chronic GVHD, 23 with inactive chronic GVHD, and 12 with no chronic GVHD), 
and  ‘group 2’ of 25 patients prospectively followed with samples obtained every 3 
months from time of HCT (including 8 who did not develop chronic GVHD by 12 months 
post-HCT and 17 who developed chronic GVHD between 3 and 12 months post-HCT). 
B cell phenotype was studied following isolation of lymphocytes from whole blood 
samples using the Ficoll method. Soluble BAFF from plasma samples was determined 
using enzyme-linked immunosorbent assay (ELISA). In the group 1, comparisons were 
made in BAFF level, CD19+ B cell numbers, and BAFF to B cell ratio: Those with active 
chronic GVHD had significantly greater BAFF, lower CD19+ B cell number, and greater 
BAFF to B cell ratio compared to those with inactive chronic GVHD, no prior chronic

GVHD, and 33 healthy controls. As well, antigen naïve B cells 
(CD19+IgD+CD38LoCD27-) were significantly lower in those with chronic GVHD 
compared to patients without chronic GVHD. Conversely, CD27+ B cell subsets (IGD+ 
memory B, Pre-GC, Post-GC memory B, and plasmablast/plasma cell (PB/PC)) 
proportions were greater in those with active chronic GVHD compared to other groups. 
Increasing BAFF levels correlated with increasing numbers of activated pre-GC and 
PB/PC cells in chronic GVHD.  
In the prospective (‘group 2’) cohort, serial BAFF levels, B cell numbers and phenotype 
were measured at 3 month intervals from HCT. In patients (n=8) who did not develop 
chronic GVHD and patients following autologous transplant (n=8), BAFF levels were 
elevated early after transplant at 1 and 3 months. In these two groups, BAFF levels 
declined as B cell numbers increased. In the 17 patients who developed chronic GVHD, 
BAFF levels remained high despite low B cell numbers. While the proportion of CD27+ 
B cells decreased as BAFF levels returned to normal in those who did not develop 
chronic GVHD, those with chronic GVHD had elevated CD27+ B cells that persisted 
over 12 months following HCT. A consolidative model suggests that, in patients who 
develop chronic GVHD, high BAFF levels and decreased numbers of naïve B cells (high 
BAFF/B cell ratio) support alloreactive pre- and post-germinal center CD27+ B cells that 
contribute to chronic GVHD development. 
 
Ofatumumab – summary of pharmacokinetics, toxicology, and human clinical trial 
data 
Ofatumumab ( also known as HuMax-CD20) is a human immunoglobulin G1 kappa 
(IgG1κ) monoclonal antibody (mAb) which targets a unique epitope on the CD20 
molecule.  
 
Nonclinical Pharmacology 
Binding of ofatumumab causes clustering of CD20 on the cell surface and cell death 
through the induction of complement mediated cytotoxicity (CDC) and antibody 
dependent cell mediated cytotoxicity (ADCC). In vitro studies showed that ofatumumab 
is able to kill tumor B cells including those with low CD20 expression, such as primary 
chronic lymphocytic leukaemia (CLL) cells, and cells with high expression of 
complement defense molecules. Compared to rituximab, ofatumumab showed potential 
in nonclinical studies to be more potent at inducing CDC, especially in cells with low 
CD20 expression. As a fully human antibody, ofatumumab is predicted to be less 
immunogenic than rituximab, which is a chimeric monoclonal antibody. 
 
Nonclinical Pharmacokinetics and Toxicology 
An in vitro human tissue cross-reactivity study has confirmed that ofatumumab binding 
is restricted to B cells within the peripheral blood circulation and human lymphoid 
tissues, suggesting there is little likelihood of non-pharmacologically mediated effects.  
In monkey repeat dose toxicity studies, ofatumumab elicited the predicted 
pharmacological response; specific binding of ofatumumab to CD20+ B cells and the 
induction of cell death. Intravenous (IV) administration to monkeys for up to 7 months

profoundly decreased circulating B cells and resulted in moderate germinal center and 
follicular atrophy in the lymph nodes, Peyer’s patches and spleen. Following clearance 
of ofatumumab, repletion of B cell counts and a reversal of the tissue changes noted 
during the study were observed. Subcutaneous (SC) administration to monkeys in the 2 
dose subcutaneous and intravenous bridging study demonstrated similar changes in the 
depletion and recovery of B cells. The pharmacokinetics of ofatumumab was typical of a 
monoclonal antibody with low clearance, a small volume of distribution and a relatively 
long half-life. 
There were no other ofatumumab-related systemic effects (including effects on the 
delayed type hypersensitivity response) or histopathological changes in monkeys 
following chronic exposure to ofatumumab. However, a minor reduction in the 
magnitude of the immunoglobulin G (IgG) response to the keyhole limpet haemocyanin 
(KLH) antigen was noted in monkeys dosed at 20 and 100 mg/kg. 
There were 5 unscheduled deaths in the intravenous 7 month repeat dose study. Three 
out of 42 monkeys succumbed to a probable C. jejuni infection; a common yet 
problematic fecal-oral transmitted pathogen in monkeys. This infection was not 
considered to be ofatumumab treatment-related and no increase in susceptibility to 
infection has been reported in the clinical studies. Hemolytic anemia occurred in 2 out of 
42 monkeys in the 7 month study. Both of these monkeys had a positive direct Coombs’ 
test indicative of the presence of anti-drug antibodies (ADAs). It is most likely that the 
hemolytic anemia was due to a strong ADA response to ofatumumab, which induced 
immune complex formation. Binding of immune complexes to the surface of the red 
blood cells is thought to have resulted in sequestration of the coated red cells in the 
spleen causing the hemolytic anemia.  
ADAs have been detected in several monkey toxicity studies following both IV and SC 
administration. However, no toxicities directly associated with the ADAs have been 
reported and an ADA response in monkeys is not considered indicative of an ADA 
response in humans. No maternal toxicity, adverse effects on embryofetal development 
or teratogenicity occurred in the monkey embryofetal development study at doses up to 
100 mg/kg. The effect on human pregnancy is unknown.  
 
Effects in Humans 
Pharmacokinetics and pharmacodynamics 
Pharmacokinetic data are currently available from eight completed studies (Study Hx- 
CD20-001, Study Hx-CD20-402, Study Hx-CD20-406, Study OMB111148, Study 
OMB112758, Study Hx-CD20-403, Study OFA110867, and Study EN414/OMS115102), 
three concluded studies (Study Hx-CD20-405, Study Hx-CD20-407, and Study Hx-
CD20-409), and two ongoing studies (Study GEN410/OFA110635 [double-blind and 
open-label treatment periods completed], and Study GEN411/OFA110634 [completed 
up to 24 weeks]). Ofatumumab was administered by IV infusion in all studies except 
Study OFA110867, in which it was given by subcutaneous (SC) injection. After repeated 
IV administration, clearance and volume of distribution values were low and half-life 
values were long for ofatumumab, as seen with other monoclonal antibodies. 
Statistically significant increases in AUC, Cmax, and t½ values and decreases in CL

values were found between the first and last infusions. These findings are likely due to 
the rapid and sustained depletion of CD20+ B cells after first infusion, leaving a reduced 
number of B cells available for the antibody to bind at subsequent infusions.  
Subcutaneous administration of a single dose of ofatumumab ≥30 mg in subjects with 
RA similarly resulted in rapid and sustained B-cell depletion. 
 
Summary of safety data 
Infusion reactions in the IV program are common adverse events (AEs) that are 
generally mild to moderate in severity, and have been mitigated by premedication and 
slower IV administration. Severe infusion reactions have been reported, and have 
occasionally led to temporary interruption or withdrawal of ofatumumab. Adverse events 
in the SC program to date have also shown severe reactions, but overall, most AEs 
have been generally mild to moderate, and have been considered as post-injection 
systemic reactions (PISRs). Infectious events including lower respiratory tract infections 
and cytopenias that include neutropenia, anemia, and thrombocytopenia have been 
observed in oncology trials with ofatumumab, but these events are commonly reported 
with the diseases under study and/or other concomitant therapies. Neutropenia and 
serious infections have also been reported in RA studies, but these generally occurred 
at a similar frequency between the ofatumumab and placebo groups. 
 
Safety data from clinical trials utilizing the proposed dose/schedule of 
ofatumumab  
In a phase I/II study of escalating dose ofatumumab (300mg, 700mg or 1,000mg 
delivered on days 0 and 14) for rheumatoid arthritis (RA) patients who had failed prior 
disease modifying (DMARD) therapy, the study therapy was generally well tolerated. 
Part A was a double-blind, placebo-controlled, dose escalation study with randomized 
treatment allocation within each of 3 sequential dose cohorts. Subjects received 2 
infusions on Day 0 and Day 14 of either ofatumumab (300 mg: n=12; 700 mg: n=10; 
1000 mg: n=10) or placebo (n=7) and were followed for safety, efficacy, and PK 
measurements for 24 weeks. Part B was a double-blind, placebo-controlled parallel 
group study with randomization (1:1:1:1) into 1 of 4 treatment arms. Subjects received 2 
infusions on Day 0 and Day 14 of either ofatumumab 300 mg (n=58), 700 mg (n=57), 
1000 mg (n=54), or placebo (n=56) and were followed for safety, efficacy, and PK 
measurements for 24 weeks. In addition, following implementation via a protocol 
amendment, efficacy data, selected safety data (B cells, immunoglobulins, and SAEs) 
and samples for HAHA analysis were collected at Weeks 36 and 48. Pre-medication 
with corticosteroids was not initially required; however, based on severe infusion-related 
reactions reported during Part A and Part B, the protocol was amended to include pre-
medication with corticosteroids, an additional dose of antihistamine, and an increased 
infusion volume and infusion time. 
A total of 214 AEs in 37 subjects were reported in Study 403 Part A. The most 
frequently reported AEs were nausea, fatigue, urticaria, hypotension, rash, pyrexia, 
vomiting, diarrhea, chills, dyspnea, headache, hyperhidrosis, and leukocyturia. A total of 
164 AEs were reported in the ofatumumab treatment groups; these AEs were generally 
of mild or moderate intensity, while 7% (12 events) were severe and one was life-

threatening (anaphylactoid-like reaction). Adverse events judged as related to study 
product were mainly infusion-related and were also those most frequently reported. The 
most frequent symptoms reported on an infusion day were rash, urticaria, and 
hypotension. Of the AEs reported in the ofatumumab groups, 79/164 (48%) were 
reported on an infusion day. Among these, AEs were reported with substantially higher 
frequency on the first infusion day (74/79, 94%) compared with the second infusion day, 
with no evidence of a dose effect. 
 
The safety population for Part B comprised all 225 exposed subjects. A total of 81%, 
84%, 85%, and 57% of subjects in the 300 mg, 700 mg, 1000 mg, and placebo groups, 
respectively, reported at least one AE. Among the 675 AEs reported, 66% (356/540) in 
the active dose groups and 41% (55/135) in the placebo group were considered as 
related to study drug. The most frequently reported AEs in the total active treatment 
group were rash, throat irritation, dyspnea, pharyngolaryngeal pain, nausea, pruritus, 
and urticaria (Table 36). A total of 540 AEs were reported in the ofatumumab treatment

10 

group; these AEs were generally of mild-to-moderate intensity, with 32 severe and 2 
life-threatening events (breast cancer and pneumonitis).  
 
A total of 3 SAEs were reported in Study 403 Part A; 2 in the 300 mg dose group and 1 
in the 1000 mg dose group. In the 300 mg dose group, 1 event each of anaphylactoid 
reaction and urticaria were reported and both were considered related to ofatumumab. 
The anaphylactoid-like reaction occurred in a subject premedicated only with 
paracetamol and antihistamine and prior to optimized rate of administration and was of 
Grade 4 intensity. Symptoms included urticaria, hypotension, loss of consciousness, 
and vomiting. The subject recovered after treatment with calcium and corticosteroids. 
One subject experienced Grade 2 urticaria; ofatumumab infusion was paused, but when 
restarted the urticaria worsened. Treatment was discontinued and the urticaria resolved 
after 2.5 hours. One event of cardiac ischemia was reported in the 1000 mg dose group 
and was considered unrelated to treatment with ofatumumab. No deaths were reported. 
Two SAEs were reported during the Part A follow-up period as follows: cellulitis in one 
subject in the 700mg group and intervertebral disc protrusion in one subject in the 
1000mg group. Neither event was considered related to treatment with ofatumumab by 
the investigator. In part B, a total of 36 SAEs were reported in 26 subjects (24 events up 
to Week 24 and 12 events between Week 24 and Week 48). A higher incidence of 
SAEs, primarily infusion-related events, was observed in the 1000 mg group compared 
with the placebo, 300 mg, or 700 mg groups. No AEs had a fatal outcome.  Of the 11 
SAEs considered related to ofatumumab, 5 were infusion related, with 4 of the 5 
infusion-related SAEs having occurred prior to implementation of the final protocol 
amendment that optimized the pre-medication regimen to decrease the frequency and

intensity of infusion-related reactions. Of the remaining, there were 3 infections 
(bronchopneumonia, urinary tract infection, cellulitis) and 1 event each of pneumonitis, 
exacerbation of RA, and breast adenocarcinoma. The subject with the pneumonitis had 
been receiving MTX, for 5 years. Other than infusion-related events, a review of the 
safety data including the serious events from this study did not provide evidence of a 
causal relationship between the reported events and ofatumumab use.  
 
 
Summary of efficacy data 
Efficacy in follicular lymphoma 
In Study Hx-CD20-001, 15 of 37 (41%) evaluable subjects with FL obtained objective 
responses across all ofatumumab dose groups (300 mg, n=8: 63%; 500 mg, n=9: 33%; 
700 mg, n=10: 20%; and 1000 mg, n=10: 50%) and included 4 (11%) subjects with 
complete response (CR), 3 (8%) subjects with CRu, and 8 (22%) subjects with PR. A

total of 19 (51%) subjects had SD and 3 subjects had PD. The median TTP for all 
subjects was 8.8 months and the median duration of response was 29.9 months. The 
time to next FL therapy was not reached during the study. In Study Hx-CD20-405, a 
total of 116 subjects were treated with two dose levels of single-agent ofatumumab. The 
ORR in the total population was 11%. This group of subjects was highly refractory with 
65% refractory to their last chemotherapy. Subjects in the study had previously received 
a median of 4 prior treatment regimens. The 1000 mg dose group (n=86) demonstrated 
an ORR of 10% (1 CR, 8 PR). In addition, 50% of subjects in the 1000 mg treatment 
arm had stable disease (SD). The ORR among subjects in both treatment arms who 
were refractory to prior rituximab monotherapy (n=27) was 22%. The ORR in subjects 
who were refractory to rituximab in combination with chemotherapy was 7%, and the 
ORR among subjects refractory to rituximab maintenance was 9%. Median PFS was 
3.2 months in the 500 mg dose group and 6.0 months in the 1000 mg dose group. At 
the time of this analysis, median OS was 31.7 months in the 1000 mg dose group (not 
estimable in the 500 mg dose group, as the estimated curve for OS did not cross the 
horizon line that represents the survival probability of 50%). In Study Hx-CD20-409 
(N=58), subjects with previously untreated FL were randomized to two dose levels of 
ofatumumab in combination with CHOP: 300 mg of ofatumumab (cycle 1) followed by 
500 or 1000 mg of ofatumumab (cycles 2-6), in combination with CHOP, every 3 weeks 
for 6 cycles. Results demonstrated an ORR of 90% in the 500 mg group (n=29) and 
100% in the 1000 mg group (n=29). For the secondary endpoint of complete response, 
the rate was 21% for the 500 mg group and 31% for the 1000 mg group. 
 
Efficacy in chronic lymphocytic leukemia (CLL) 
In Study Hx-CD20-402 (N=33), ofatumumab treatment in subjects with relapsed or 
refractory CLL led to a 48% ORR in the highest dose group, Group C (n=27; 1st dose: 
500 mg; 2nd, 3rd, and 4th dose: 2000 mg), and included 12 (44%) subjects with PR and 
1(4%) subject with nodular partial response (nPR). One of the subjects showed all 
features of an nPR at Week 19 except that residual lymphadenopathy was identified by 
computed tomography (CT). For Group C, the median TTP was 15.6 weeks in the full 
analysis population and 23 weeks in the subgroup of responders. The median duration 
of response was 16 weeks and the median time to next CLL therapy was 52.4 weeks. 
In Study Hx-CD20-406 (N=154 as of the interim data cutoff of 19 May 2008;N=223 in 
the final CSR analysis), the protocol-defined results of ORR as assessed by an 
Independent Review Committee (IRC), demonstrated that the ofatumumab regimen is 
effective in subjects with CLL who are either refractory to both fludarabine and 
alemtuzumab (i.e., DR) or who are refractory to fludarabine and considered 
inappropriate for alemtuzumab treatment due to the presence of bulky (>5cm) 
lymphadenopathy (i.e., BFR). Additionally, ofatumumab was effective in “Other” 
subjects who failed fludarabine but were enrolled in the study prior to Amendment 3 and 
did not meet the further classification criteria of either DR or BFR defined in the 
amendment. The information from this interim data analysis formed the basis of the 
regulatory approval in the US, EU, Australia, Switzerland, and Croatia as ARZERRA™, 
for the treatment of patients with CLL refractory to fludarabine and alemtuzumab. 
Improvements in the individual components (i.e., constitutional symptoms, 
organomegaly, lymphadenopathy) of the response assessment as well as ECOG 
performance were observed. Of note, the median lymphocyte count and median lymph

node size decreased rapidly and continued to decrease during the treatment period in 
the majority of subjects [ARZERRA Prescribing Information, 2010]. The primary 
endpoint analysis of 223 subjects in Study Hx-CD20-406 included subjects 
in the DR (N= 95), BFR (N= 112), and Other (N=16) groups. The ORR was 49% (47/95) 
in the DR group, 43% (48/112) in the BFR group, and 63% (10/16) in the Other 
group. Among the 105 responders, 2 subjects in the BFR group achieved CR, 47 
subjects in the DR group achieved PR, 46 subjects in the BFR group achieved PR, and 
9 subjects in the Other group achieved PR. An additional 33 subjects in the DR group, 
52 subjects in the BFR group, and 4 subjects in the Other group achieved SD. The 
median duration of response was 5.5 months, 6.4 months, and 7.4 months in the DR, 
BFR, and Other groups, respectively. The median PFS was 4.6 months, 5.5 months, 
and 8.9 months in the DR, BFR and Other groups, respectively. The median overall 
survival (OS) was 13.9 months in the DR group, 17.4 months in the BFR group, and 
28.3 months in the Other group. In Study Hx-CD20-407 (N=61), subjects with previously 
untreated CLL obtained objective responses. The ORR in the 500 mg group was 77% 
and in the 1000 mg group was 73%. CR were observed in 32% of subjects (10/31) in 
the 500 mg group and in 50% of subjects (15/30) in the 1000 mg group. Overall, across 
both dose groups 25 subjects had CR, 19 subjects had PR, 2 subjects had nPR, 5 
subjects had SD and 7 subjects had PD. Time-to-event endpoints were measured over 
2 years. Median duration of response was 32.0 months for the 500 mg group (not 
estimable for the 1000 mg group). Median PFS was 33.0 months for the 500 mg group 
and 23.5 months for the 1000 mg group. Time to next anti-CLL therapy was 31.9 
months for the 500 mg group and 26.7 months for the 1000 mg group. In Study 
OMB111148 (N=6), a total of 6 subjects with CLL were treated with two dose 
levels of single-agent ofatumumab. The ORR in the 6 subjects was 50%. All 3 subjects 
in the 1000 mg group had PR. In the 500 mg group, 1 subject had SD and 2 subjects 
had PD. The median PFS for all subjects was 32.1 weeks and the median duration of 
response was 30.8 weeks in the 1000 mg group. In Study OMB112758, conducted in 
Japan and Korea, 10 subjects received 8 weekly intravenous infusions of ofatumumab 
(1st dose: 300 mg; 2nd – 8th dose: 2000 mg) followed 5 weeks later by 4 monthly 
infusions of 2000 mg ofatumumab. For the 10 subjects, the overall response rate (PR or 
better) was 70% as assessed by the independent reviews; all of the seven responders 
had PR. The remaining 3 subjects had SD. 
 
Efficacy in diffuse large B-cell lymphoma 
In Study GEN415/OMB111776, 81 subjects with CD20+ relapsed DLBCL ineligible for 
autologous stem cell transplantation or DLBCL which had relapsed or progressed after 
autologous stem cell transplantation were treated with ofatumumab 300 mg for the first 
IV infusion, followed by seven weekly infusions of ofatumumab 1000 mg. The ORR was 
11% (3 CR and 6 PR). In Study OMB110927, 61 subjects with relapsed or refractory 
CD20+ aggressive B-cell NHL who were transplant eligible were treated with  
ofatumumab + ICE (n=35) or ofatumumab + DHAP (n=26). Chemotherapy was dosed 
every 21 days for 3 cycles, while ofatumumab was dosed on Day 1 and Day 8 of Cycle 
1, and on Day 1 of Cycles 2 and 3 (initial dose 300 mg, n=21; or 1000 mg, n=40; all 
subsequent doses 1000 mg). The ORR in the 59 evaluable subjects was 61% with CR 
in 37%.

Efficacy in rheumatoid arthritis 
As of 21 December 2011, efficacy results are available from 3 studies in subjects with 
RA: Study Hx-CD20-403/OFA112657 Part A and Part B clinical study reports 
(completed Sept 2008) and follow-up period addenda (completed Dec 2010 and Jan 
2011, respectively); Study GEN410/OFA110635 (two interim clinical study reports for 
the double-blind and open-label periods, completed June 2010 and Dec 2011, 
respectively); Study GEN411/OFA110634 (one interim clinical study report for the 
double-blind period, completed August 2011).  
 
In Study Hx-CD20-403 Part A and B, all of the doses tested (300 mg, 700 mg and 1000 
mg) resulted in profound B-cell depletion and B-cell levels below normal range or 
baseline were sustained for approximately 20-34 months. For the primary endpoint 
analysis (ACR20 response at 24 weeks) in Part B, all doses of ofatumumab were 
significantly better than placebo, with an ACR20 response being achieved by 40% 
(p<0.001), 49% (p<0.001), and 44% (p<0.001) of subjects in the 300 mg (n=58), 700 
mg 
(n=57), and 1000 mg (n=54) ofatumumab groups, respectively, compared with 11% in 
the placebo group (n=55). For the 700 mg and 1000 mg groups, significantly better 
improvements in ACR20 and ACR50 response rates were maintained out to 48 weeks 
compared with placebo. Subgroup analyses for the subjects on background MTX 
(n=174) showed slightly higher response rates in this subject group. 
 
Study GEN410/OFA110635, a double-blind, randomized, placebo-controlled trial of the 
efficacy of ofatumumab in RA patients with an inadequate response to MTX, completed 
its 24-week double-blind period during the previous IB reporting period, and the 
open-label extension part was prematurely terminated by the Sponsor during the current 
reporting period as the clinical development of the intravenous route of ofatumumab 
administration in RA will no longer be pursued; the follow-up period is still ongoing. For 
the double-blind period, eligible subjects were randomized (1:1) to receive two 
intravenous infusions of either ofatumumab 700 mg or placebo two weeks apart (one 
course), in addition to background MTX treatment. In the intention-to-treat study 
population, comprising 260 patients, results demonstrated that a statistically significantly 
better ACR20 response at 24 weeks (primary endpoint) of 50% (64/129; p<0.001) was 
achieved for patients receiving ofatumumab compared to 27% (35/131) in the placebo 
group. Efficacy appeared to be observed by 8 weeks and the response was sustained 
throughout the double-blind period. Statistically significant improvements in favour of 
ofatumumab were also observed for all other key secondary efficacy endpoints 
[(ACR50, ACR70, ACRn, EULAR (European League Against Rheumatism) and Disease 
Activity Score (DAS28)] [Taylor, 2011]. All subjects who completed the 24-week double-
blind period without receiving rescue disease-modifying anti-rheumatic drug (DMARD) 
treatment were eligible to proceed into the 120-week open-label period to receive repeat 
treatment courses with ofatumumab, which were given at individualized time intervals 
only if a clinical response had been achieved following the previous treatment course. 
As this study was prematurely terminated by the Sponsor ofatumumab treatment was 
discontinued by protocol amendment 5, dated 28 October 2010, and subjects 
proceeded to the ongoing Follow-up period at their next scheduled visit. An interim 
analysis of the open-label period was performed. No statistical analyses were

performed on data from the open-label period; data were summarized per “treatment 
course” using appropriate descriptive statistics. The open-label population (subjects 
who received ofatumumab during the open-label period) included 231 subjects. The 
mean (SD) for the minimum DAS28-ESR score (i.e. average lowest level of disease 
activity) was 4.01 (1.396) during the first ofatumumab treatment course and ranged from 
3.34 (1.326) to 3.82 (1.588) for treatment courses 2 to 6; the seventh treatment course 
only included 2 subjects. The mean (SD) for the minimum change from baseline in 
DAS28-ESR score (i.e. average greatest change in disease activity) was -2.32 (1.192) 
for the first treatment course; a negative change represents an improvement in 
symptoms of disease. For subsequent treatment courses the mean (SD) for the 
minimum change from baseline in DAS28-ESR score ranged from -1.45 (0.845) to -1.77 
(1.015) except for the seventh treatment course which only included 2 subjects. Based 
on DAS28-ESR, 90 subjects (37%) achieved disease remission (DAS28 score <2.6) 
and an additional 83 (34%) subjects had low disease activity (DAS28 ≥2.6 and <3.2) at 
some time during the double-blind and/or open label periods. When considered by 
treatment course, the percentage of subjects achieving disease remission ranged from 
16 to 42%, and the percentage of subjects with low disease activity ranged from 9 to 
28% (except for the seventh treatment course which only included 2 subjects). Based 
on DAS28-CRP, 125 subjects (51%) achieved disease remission and an additional 88 
(36%) subjects had low disease activity at some time during the double-blind and/or 
open label periods. When considered by treatment course, the percentage of subjects 
achieving disease remission ranged from 29 to 46%, and the percentage of subjects 
with low disease activity ranged from 13 to 18% (except for the seventh treatment 
course which only included 2 subjects). Therefore, during each treatment course there 
was an improvement in disease activity following ofatumumab treatment, in addition to 
background MTX. Disease remission or low disease activity was achieved at some time 
during the double-blind and/or open label periods by 71% of subjects based on DAS28-
ESR, and by 88% of subjects based on DAS28-CRP. 
 
Study GEN411/OFA110634, a double-blind, randomized, placebo-controlled trial of the 
efficacy of ofatumumab in RA subjects with an inadequate response to TNF-α 
antagonist therapy, was prematurely terminated by the Sponsor during the current 
reporting period. An interim analysis of the double-blind period has been completed. 
Because of premature termination only 169 subjects (out of 236) were randomized. This 
was an insufficient number of subjects to achieve 90% power for the primary endpoint, 
and therefore no statistical testing was performed for the primary and secondary 
endpoints. Data were summarized using appropriate descriptive statistics. For the 
double-blind period, eligible subjects were randomized (1:1) to receive 2 infusions of 
either ofatumumab 700 mg or placebo 2 weeks apart (one treatment course), in addition 
to background MTX treatment. Ofatumumab, in addition to background MTX treatment, 
reduced the clinical signs and symptoms of RA in this population of patients with an 
inadequate response to TNF-α antagonist therapy, after a single treatment course of 2 
infusions separated by 2 weeks. Efficacy was sustained throughout the double-blind 
period.

Efficacy in multiple sclerosis 
Study GEN414/OMS115102 has completed both the 48-week (with 24 week cross-
over), double-blind, placebo controlled treatment phase and the individualized follow-up 
phase. In the Week 0 to 24 period the majority of subjects'CD19+ and CD20+ levels 
were suppressed to zero; recovery started for the 100 mg and 300 mg active/placebo 
groups after approximately 12 and 20 weeks, respectively. In the 700 mg active/placebo 
group, all but one subject had a persistent and complete CD19+ suppression at Week 
24 In the Week 24 to 48 period the majority of the subjects' CD19+ and CD20+ levels 
were suppressed to zero (mm3) within one week in subjects who received active 
treatment after the treatment cross-over phase. Recovery started for the subjects in the 
100 mg placebo/active group after approximately 16 weeks (from these subjects’ first 
infusion). In the 300 mg and 700 mg placebo/active groups, all subjects but one (700 
mg) had persistent and complete CD19+ suppression at Week 48. Review of the raw 
summary statistics highlight the minimal amount of observed new MRI lesion activity 
following administration of IV ofatumumab in both the Week 0-24 and Week 24-48 
treatment periods. Statistical analyses supported the observations from the raw data, 
showing statistically significant benefits in favour of ofatumumab; caution is needed in 
the interpretation of the analyses in this small dataset due to the extreme skew in the 
dataset collected and the assumptions made in the analyses. The observations were 
consistent in the majority of the exploratory endpoints (cumulative number of new T1 
Gd-enhancing lesions, cumulative number of total T1 Gd-enhancing lesions and 
cumulative number of new and/or enlarging T2 lesions). The assessment of relapses 
did not show statistically significant differences in ofatumumab treatment from placebo.  
Although this was primarily a safety and tolerability trial, it also aimed to confirm CD20+ 
depletion and to obtain preliminary evidence of efficacious effect on MRI and clinical 
endpoints. The data demonstrated that ofatumumab induced a disease activity 
response and, as expected, ofatumumab caused profound and selective CD20+ 
reductions. Overall, the efficacy endpoints indicated that ofatumumab is potentially 
effective in RRMS patients. 
 
Summary of trial rationale 
Chronic GVHD is a major source of morbidity, mortality, and impaired quality of life after 
HCT. Despite prophylactic immune suppressive agents delivered prior to and following 
HCT, the majority of patients will develop chronic GVHD. The currently accepted 
primary therapy of chronic GVHD, namely 1mg/kg or greater of prednisone or 
equivalent, is ineffective, and available immune suppressive agents have limited activity 
in those who fail primary therapy. These all speak to the need for more effective primary 
therapy for chronic GVHD. Based on compelling clinical and basic insights into chronic 
GVHD biology, anti-CD20 based therapy has great potential to improve the success of 
chronic GVHD therapy. Thus, we propose a phase I-II study of combined ofatumumab 
and standard glucocorticoids to study the safety and efficacy of this approach.

II. STUDY OBJECTIVES 
Primary Objectives:  
1. Phase I: Determine the safety of ofatumumab in combination with steroids in the 
primary therapy of chronic GVHD 
2. Phase II: Determine overall response rate (CR+PR) at 6 months to ofatumumab 
and glucocorticoid primary therapy of chronic GVHD. 
 
Secondary Objectives: 
1. Determine 6 month complete response rate to ofatumumab and steroids in the 
primary therapy of chronic GVHD. 
2. Examine cumulative incidence of non-relapse mortality and primary disease 
relapse, and estimate overall survival from time of therapy. 
3. Report utilization of second-line immune suppressive therapies. 
4. Examine  incidence of complete discontinuation of immune suppressive therapy . 
5. Determine failure-free survival (composite outcome of death, relapse and 
requirement for secondary immune suppressive agents) and treatment success 
(composite outcome defined as complete resolution of all reversible chronic 
GVHD manifestations, discontinuation of all systemic immune suppressive 
agents, and freedom from death or primary malignancy relapse). 
6. Evaluate serial measures of patient-reported outcomes following therapy, 
including functional ability, symptom burden, and quality of life. 
7. Perform allied biologic studies for total B cells, B cell subsets, immune globulin 
levels, BAFF levels, and examine association between these biologic endpoints 
and clinical response to primary therapy. 
 
III. STUDY DESIGN AND ENROLLMENT CRITERIA 
Summary of Trial design 
This is a phase I-II trial to examine the safety and efficacy of prednisone and escalating 
dose of ofatumumab for the primary therapy of chronic GVHD. Prednisone will uniformly 
be initiated at 1 mg/kg/day, and the phase I component will test an escalating dose of 
ofatumumab at cohorts of 300mg, 700mg, and 1000mg given on day 0 and 14 of study. 
In the phase II component, patients will be followed for total of 24 months (including 
study therapy day 0 and day 14, and then months 1, 3, 6, 12 after therapy, then at 18 
and 24 months following therapy), and the primary efficacy endpoint of overall response 
to therapy will be determined at 6 months following initiation of therapy. Additional 
secondary endpoints and biologic correlative studies will be performed at the indicated 
time points.

IV. STUDY THERAPY 
i. Prednisone therapy 
Starting dose of prednisone will be 1mg/kg body weight per day. If patients are treated 
with alternative steroid agents (e.g. methylprednisolone), this should be dosed to the 
corresponding prednisone equivalent of 1 mg/kg actual body weight.  
The specific duration of prednisone therapy and tapering schedule for prednisone is not 
dictated by this protocol. However, the following serves as a guide for management of 
prednisone and other immune suppressive agents: 
1. Start prednisone at 1 mg/kg/day  
2. Continue this dose for 2-4 weeks or longer as needed in the setting of ongoing 
clinical improvement in chronic GVHD manifestations 
3. With stable or improving chronic GVHD manifestations, begin taper on an every 
1-2 week schedule with a target of reaching 0.5mg/kg/day 
4. Continue 0.5mg/kg/day for 4 week plateau  
5. Then taper by 10-20% of total dose per month as tolerated 
6. In setting of increase chronic GVHD activity upon taper, increase prednisone 
dose as needed, with upper limit of 1-2mg/kg/day  
7. Following complete discontinuation of prednisone, begin taper of other immune 
suppressive agents as tolerated.

Ofatumumab Administration 
Ofatumumab will be administered by IV infusion, with cohort-dependent dosing in the 
phase I dose escalation component of this study. Following definition of the 
ofatumumab MTD in the phase I component, this dose will be carried forward as the 
recommended phase II dose.  
 
The following dose cohorts to be tested in the phase I component:  
      (cohort -1): 100mg days 0 and 14 
cohort 1: 300mg days 0 and 14 
cohort 2: 700mg days 0 and 14 
cohort 3: 1000mg days 0 and 14 
 
*cohort/dose level -1 (100mg days 0 and 14) will be pursued only if 2/3 patients in 
cohort 1 (300mg days 0 and 14) experience DLT.

Ofatumumab Infusion Set up 
Ofatumumab must be administered by i.v. infusion through an in-line filter and through a 
well-functioning i.v. catheter (i.v. cannula) into a vein in the arm (or other venous 
access) by an infusion pump.   
Please Note:   It is mandatory to use an in-line low protein binding 0.2 micron 
polyether sulfone filter for all IV dosing of ofatumumab drug product. 
 
DO NOT ADMINISTER AS AN INTRAVENOUS PUSH OR BOLUS. 
 
Ofatumumab should not be mixed with any other medication.  If ofatumumab is to 
be dosed through an in-dwelling catheter, then, any previous medication should 
be removed by flushing with normal saline prior to dosing with ofatumumab. 
Please note that the infusion site can be used for blood sampling only if there is 
no risk of contamination of the infusion needle with the saline, infusion solutions, 
or any other fluid(s).  Only a newly inserted needle can be used for the predose 
blood samples.   
• 
Check subject ID against the label on the infusion bag and ensure the expiry of 
the solution. The solution must be administered in its entirety to the subject within 
24 hours from time of preparation.   
• 
Attach the 1000mL infusion bag to the infusion set (if not done at the pharmacy). 
• 
Attach the in-line filter to the infusion set (closest to the subject; see schematic 
below). Note: The in-line filter must be used during the entire infusion. 
• 
Prime the infusion set and filter with ofatumumab (if not done at the pharmacy). 
• 
In case of a problem with the filter (i.e. clogging/blockage), please change, re-
prime the new filter, and continue the infusion.

iii. Use of topical (non-systemic) therapies for chronic GVHD  
The use of topical agents for control of chronic GVHD manifestations is part of usual 
clinical care for affected patients. Common examples include various eye drops and 
artificial tears for ocular sicca, steroid or other immune suppressive agent mouth rinses 
for oral involvement, or topical steroid creams for mild cutaneous involvement. Use of 
these agents for patients on study will not be controlled or directed by this protocol. 
Rather, use of these agents will be directed by treating clinicians as part of usual clinical 
care. Use of these agents will be recorded in data capture on each study visit. Use of 
these non-systemic therapies will not inform study endpoints that include requirement 
for additional systemic immune suppressive therapies.

iv. Supportive antimicrobial prophylaxis on study 
i. 
All patients on study must receive antimicrobial prophylaxis per BMT 
guidelines and standards for the prevention of bacterial, viral, fungal, 
and pneumocystis infections.  
 
 
V. STUDY OUTCOMES/ANALYSIS ENDPOINTS 
1. Safety 
a. Definition of DLT for phase I component: 
i. In the phase I study, dose escalation will proceed as previously 
described. The dose limiting toxicity (DLT) will be defined using 
CTCAE version 4.0 as the following: 
- Events occurring within 46 days of the last dose of drug (4 half-
lives) that are: 
a) Grade 4 infusion reactions,  
b) Grade 4 constitutional symptoms at least possibly due to 
ofatumumab,  
c) Grade 3 organ toxicities (neurologic, pulmonary, cardiac, 
gastrointestinal, genitourinary, hepatic, cutaneous) at least 
possibly due to ofatumumab,  
d) Grade 4 neutropenia lasting more than 14 days 
ii. Importantly, known infusional toxicities of ofatumumab are 
managed appropriately with modification of infusion rate or 
temporary halting of infusion, as well as with supportive care 
including IV fluids, anti-histamines, and steroids.  
iii. Specifically, grade 1-3 infusion-associated adverse events defined 
by CTC version 4.0 are not considered DLT in this trial. The 
occurrence of grade 4 infusion-associated adverse event is 
considered DLT. 
iv. According to observed toxicities in the phase I component, the 
greatest dose tolerated in the dose escalation will be carried 
forward into the phase II component of the trial as the 
recommended phase II dose. 
v. Events clearly related to chronic GVHD, relapse of the primary 
hematological disorder, concurrent medication, or infection will not 
be included as a DLT.  
vi. Plan for patients not able to be evaluated for outcome on phase I 
component: 
1. If an enrolled patient dies or comes off study following 
occurrence of DLT as defined above, this data will inform the 
 
Version 7.0 
Version Date: 3.10.2016 
30 

determination of DLT, and there will be no need to replace 
such patients. 
2. Rather, if an enrolled patient does not experience DLT 
during follow up, but decides to withdraw from the study for 
other non-DLT related reasons prior to the minimum follow 
up of 46 days, such a patient would be replaced by a newly 
accrued patient. 
 
2.  Efficacy 
a. Overall response rate 
i. Overall response rate (ORR) at 6 months following initiation of 
therapy represents the composite outcome of complete and partial 
response (CR + PR). 
ii. Complete response is defined as resolution of all reversible 
manifestations in each organ or site of chronic GVHD involvement 
iii. Partial response is defined as improvement in at least one organ or 
site without progression in any other organ or site 
b. Complete response rate 
i. Complete response (CR) at 6 months following initiation of therapy 
requires complete resolution of all chronic GVHD manifestations in 
all affected organs.  
c. Cumulative incidence of non-relapse mortality and primary malignancy relapse 
i. The cumulative incidence of non-relapse mortality (defined as 
death in the absence of primary malignancy relapse after 
transplant) and relapse (defined by usual definitions in clinical 
practice including, but not limited to morphologic, 
immunophenotypic, or molecular methods) will be estimated from 
time of study therapy initiation. These are treated as competing-risk 
events. 
d. Overall survival 
i. Overall survival will be determined from date of study therapy 
initiation, with death from any cause as the event of interest, and 
censoring at last follow up date for those with incomplete 
observations. 
e. Utilization of second-line systemic immune suppressive therapies 
i. The use of second-line systemic immune suppressive agents will 
be captured at each study visit.  
ii. This specifically refers to systemic therapies only, not topical or 
local therapies, such as topical eye drops, mouth rinses, topical 
steroid skin cream, or topical vaginal steroid agents.  
 
Version 7.0 
Version Date: 3.10.2016 
31 

iii. Adjustment in prednisone dose according to disease manifestations 
is not considered second-line therapy 
iv. Adjustment in the dose of existing immune suppressive agents that 
require dose modification to maintain therapeutic serum drug levels 
(e.g. tacrolimus, cyclosporine, sirolimus) is not considered a 
second-line therapy or change in therapy 
v. New initiation of extra-corporeal photopheresis (ECP) for 
progressive chronic GVHD manifestations following study 
intervention of prednisone and ofatumumab is considered second-
line therapy. 
f. Discontinuation of all systemic immune suppressive therapies 
i. The incidence of complete discontinuation of all systemic immune 
suppressive therapies will be determined.  
g. Failure-free survival 
i. This time-to-event outcome will be estimated with the composite 
event of death from any cause, relapse and addition of secondary 
immune suppressive agents for progressive chronic GVHD. 
h. Treatment success 
i. This endpoint will be estimated with a composite outcome of 
complete resolution of all reversible chronic GVHD manifestations, 
discontinuation of all systemic immune suppressive agents, and 
freedom from death or primary malignancy relapse after transplant.  
i. Patient-reported outcomes and functional measures 
i. Patients will provide assessment of their functional ability (grip 
strength, 2 minute walk test), symptom burden (Lee symptom 
scale), and quality of life using validated instruments recommended 
by the NIH Consensus Development Project on Chronic GVHD 
(Lee Chronic GVHD Symptom Scale,41 HAP functional scale,42 
QOL instruments SF-3643 and FACT-BMT44) 
ii. These data will be collected at baseline, 3, 6, and 12 months on 
study 
 
j. Biologic studies 
 
Peripheral blood samples will be obtained from study patients at baseline, and then 3, 6, 
and 12 months. From these peripheral blood samples, the following major analyses will 
be performed: (1) quantification of plasma B cell stimulatory factor (BAFF), (2) 
quantification of immune globulin levels, and (3) enumeration of total B cells, as well as 
characterization of B cell subsets by surface phenotype through flow cytometric 
analysis.  
 
Version 7.0 
Version Date: 3.10.2016 
32 

From whole blood samples, plasma will be separated, and utilized for determination of 
soluble BAFF levels by enzyme-linked immunosorbent assay (ELISA). From peripheral 
blood mononuclear cells (PBMC), B cells will be isolated. Antibodies targeting surface 
antigens CD19, CD20, CD38, CD27, and IgD will be utilized for staining, and the 
respective cell subsets will be characterized by flow cytometry according to phenotype: 
Naïve B cells (IgD+CD38LowCD27-), transitional B cells (IgD+CD38HighCD27-), 
IgD+ memory B cells (IgD+CD38LowCD27+), pre-germinal center B cells 
(IgD+CD38HighCD27+), post-germinal center memory B cells (IgDLowCD38LowCD27+), and 
plasmablast/plasma cell (IgDLowCD38HighCD27+). 
 
3.    Summary of pre-treatment and on-study testing to be performed 
 
- Pre-treatment assessments / screening 
 
 i.  Evaluation of eligibility: Inclusion, exclusion criteria 
ii.  Laboratory studies (CBC with differential, chemistry, liver function tests, review of 
prior hepatitis B and C, as well as HIV testing – may utilize prior HIV/hepatitis testing 
done for purpose of transplant eligibility) 
iii. Pregnancy - Women of childbearing potential must have current negative pregnancy 
test, and both men and women must agree to adequate contraception methods. 
iv. EKG 
v. assessment of Karnofsky Performance Status (KPS) 
 
 
- On-study assessments (windows described in study calendar) 
 
i.   history and physical examination, standard laboratory tests (CBC, chemistry, LFT) 
- completed screening, day 0, day 14, months 1, 3, 6, 9, 12, 18, 24

- completed screening, day 14, months 1, 3, 6, 9, 12, 18, 24 
- includes scoring of chronic GVHD severity per NIH 0-3 severity, clinician-reported 
severity measures, patient reported severity 
- includes recording of immune suppressive medications at each visit 
 
iii. Patient-reported outcomes 
- completed screening, day 14, months 1, 3, 6, 9, 12, 18, 24 
 
Version 7.0 
Version Date: 3.10.2016 
33 

- includes quality of life, Lee symptom scale, and HAP (human activity profile) 
 
iv. Functional measures 
- completed screening, day 14, months 1, 3, 6, 9, 12, 18, 24 
- includes grip strength and 2 minute walk test 
 
v. Biologic samples 
- baseline, then months 3, 6, 12 
- includes the above-described B cell subset studies and BAFF levels 
 
 
4.  Criteria for patient termination from study  
a. Patient decision to withdraw from study  
b. Death 
c. Relapse of primary hematologic malignancy  
d. End of study  
a. Phase I (those patients in dose levels that are not the MTD to be carried 
forward into the phase II component) 
i. patients will complete 46 days of follow up from last dose of 
ofatumumab to monitor for DLT 
ii. for those not in the MTD cohort, limited data will be collected at 6 
and 12 months (clinical response, pharmacodynamics) 
b. Phase II (including patients who are carried forward from the phase I 
component) – patients will complete 24 total months of follow up on study 
 
e. Clarification on duration of follow up and assessments for phase I patients 
a. As the MTD will not be known in real-time, patients on any of the phase I 
dose levels may potentially be those carried forward from the MTD cohort 
as the recommended phase II dose 
b. Accordingly, patients in all dose levels of the phase I trial will need to have 
all of the above outlined on-study assessments performed until the MTD is 
defined. 
c. Once the MTD is defined, only those patients in the MTD cohort will 
continue to have all of the ongoing assessments performed 
d. Conversely, those in the non-MTD cohorts will complete an abbreviated 
assessment measure set to include only the chronic GVHD activity 
assessments/response determination and the biologic studies (B cell 
 
Version 7.0 
Version Date: 3.10.2016 
34 

subsets, BAFF levels) at 6 and 12 month time points. These limited 
assessments for the non-MTD dose level patients will be included to 
examine the relationship between dose and clinical response, and 
dose/pharmacodynamic activity. 
 
 
VI. STATISTICAL ANALYSIS: 
Study design and sample size estimation:   
In the phase I component, dose escalation procedure is modeled after the data reported 
for ofatumumab in treatment of rheumatoid arthritis. Here, doses of 300, 700, and 
1000mg were delivered on days 0 and 14. As this dose/schedule was well tolerated, led 
to significant and sustained (up to 48 weeks) depletion of peripheral blood CD19+ B 
cells, and there was an association between escalating dose and clinical response 
(appendix A), this dose/schedule will be adapted to a phase I design in the primary 
treatment of chronic GVHD.  
The study design of the phase I component represents a traditional (3+3) dose 
escalation design with the following cohorts of ofatumumab in combination with 
1mg/kg/day prednisone therapy:  
      (cohort -1): 100mg days 0 and 14 
cohort 1: 300mg days 0 and 14 
cohort 2: 700mg days 0 and 14 
cohort 3: 1000mg days 0 and 14 
*cohort/dose level -1 (100mg days 0 and 14) will be pursued only if 2/3 patients in 
cohort 1 (300mg days 0 and 14) experience DLT. 
 
Phase I trial endpoint: 
Safety of escalating dose of ofatumumab in combination with prednisone.  
 
Definition of dose-limiting toxicity (DLT): 
Dose-limiting toxicity attributable to ofatumumab within 46 days of initiation of 
ofatumumab therapy is defined in the above section V.1 safety for definition of DLT. The 
occurrence of DLT attributable to ofatumumab in ≤ 17% serves as the boundary for the 
maximally tolerated dose (MTD) of ofatumumab. 
 
Phase I trial procedures and analysis: 
The initial group of 3 patients will be enrolled in the cohort 1. Dose escalation of 
ofatumumab will proceed according to the following: If no DLT is observed among 3 
patients in a cohort, the next group of 3 will be treated at the next highest dose level. If 
the current level (i.e., the level at which no DLTs are observed) is the highest dose 
 
Version 7.0 
Version Date: 3.10.2016 
35 

level, three additional patients will be enrolled (total of six). If one DLT is observed 
among 3 patients in a cohort, the next group of 3 will be treated at this same dose level. 
If no more DLT is observed among the 3 additional patients (i.e. one DLT in total is 
observed among the 6 patients), then the next 3 patients will be treatment at the next 
highest dose level. If at least 1 more DLT is observed among the 3 additional patients, 
then the MTD is exceeded. If 6 patients have been treated at the next lower dose level, 
it will be considered as the MTD. If not, three additional patients will be enrolled. This 
escalation approach will then be continued until a dose is identified where at most 1 of 6 
patients has a DLT. That dose will be considered to be the MTD. If two DLTs are 
observed among 3 (or fewer) patients in a cohort, the next group of 3 will be treated at 
the next lowest dose level. If the current level (i.e. the level at which 2 DLTs are 
observed) is the lowest dose level (300mg days 0 and 14), then a dose level -1 will be 
pursued, in which a de-escalated dose of 100mg ofatumumab will be given on days 0 
and 14.   
The total number treated on the phase I component will depend on the occurrence of 
dose limiting toxicity (DLT), however the maximal number accrued on the phase I study 
would approximate 12 to 18 total subjects. GSK reviewed phase I data prior to moving 
forward with the phase II component. 
 
Phase II component: 
Following definition of the maximal tolerated dose (MTD) in the phase I component, this 
MTD will be taken forward in a phase II trial to characterize the efficacy of this 
approach. The primary endpoint of interest in the phase II component is overall 
response rate (ORR) to therapy at 6 months. Overall response is defined as the 
composite of complete response and partial response. In the assessment of response 
for this primary endpoint, response will be determined according to clinician 
assessment. The Simon’s two-stage optimum design is used to minimize the expected 
sample size. With a historical baseline ORR proportion of 60% (justification for this 
baseline proportion in background section), anticipated effect leading to ORR of 80% in 
this investigational treatment (prednisone + ofatumumab), power of 90%, and alpha of 
0.1, a total of 38 subjects are needed for this analysis of efficacy. As 6 total patients 
from the phase I component will have been treated at the recommended phase II dose, 
these will be included for efficacy analysis. Early termination will occur if 6 or fewer out 
of 11 (≤6/11) subjects in first stage have a overall response (CR or PR). If the trial goes 
on the second stage and a total number of responders (CR or PR) is less than or equal 
to 26 (≤26/38), the null hypothesis fails to be rejected. To provide total of 38 subjects for 
this efficacy analysis, 32 additional patients will be enrolled in the phase II component.  
Thus, the net total number of patients to be enrolled on the combined phase I-II study 
will be a maximum of 50.  
 
Statistical Analysis plan: 
The ‘All Treated population’ will be used for the analysis of the efficacy and safety 
endpoints. Specifically, this will consist of all patients who receive at least one dose of 
study treatment. For Complete Response (CR) rate and Overall Response rate:  A 
 
Version 7.0 
Version Date: 3.10.2016 
36 

patient with unknown or missing response will be treated as a non-responder (i.e. the 
patient will be included in the denominator when calculating the percentage). 
Overall response (ORR) rate will be determined at 6 months and will be reported with 
associated 95% confidence interval. Complete response rate will be similarly reported. 
Association between clinical variables (chronic GVHD severity, organ involvement, 
patient socio-demographic data, disease and transplantation variables) and response 
will be examined. Patient reported outcomes will be reported, and association between 
scores on individual measures (chronic GVHD symptom scale, human activity profile, 
QOL instruments including SF-36 and FACT-BMT) and clinical response to therapy will 
be explored. Cumulative incidence of relapse and non-relapse mortality will be 
estimated, accounting for competing risk events. Overall survival from date of therapy 
initiation will be estimated by Kaplan-Meier method, and survival curves among relevant 
subgroups will be compared utilizing the log-rank test. In the analysis of survival time 
between responders and non-responders, landmark analysis will be utilized to avoid 
biased survival estimation. Other time-to-event secondary endpoints (e.g. failure-free 
survival) will similarly be estimated using the Kaplan-Meier method. Biologic endpoints 
(total B cell numbers, B cell subsets, immune globulin levels, BAFF levels) will be 
summarized. Comparisons between relevant groups will be made at specific time points 
utilizing parametric (e.g. t-test) or non-parametric (e.g. Wilcoxon rank-sum) as 
appropriate per the nature of the data. Additionally, change in these values over time 
will be examined according to response vs. non-response to primary therapy with 
mixed-model approach.  
 
Early Stopping Rule for Toxicity 
An early stopping rule for toxicity is constructed to continuously monitor the rate of DLT 
(i.e. grade 4 AE attributable to ofatumumab per the above definitions) for the 38 patients 
in a Phase II component. The DLT is defined in Section V.1. Safety. The stopping 
boundaries for monitoring the DLT is constructed as a Pocock-type boundary as 
described in “Continuous Toxicity Monitoring in Phase II Trials in Oncology” by Ivanova, 
Qaqish, and Schell (Biometrics, 2005; 61(2):540-45). Table below shows the number of 
DLTs allowed for a given number of “assessable” patients up to that point. Patients are 
considered to be “assessable” when they have either experienced a DLT or completed 
the surveillance period (death without a DLT or 30 days after infusion of Ofatumumab) 
without having experienced a DLT so that their outcomes are identifiable. Up to 20% of 
DLT rate is expected or acceptable. The table below contains the stopping boundaries 
for toxicity, based on which the probability of early stopping is at most 0.05 if the DLT 
rate is equal to 6.5%. Given the first 6 patients on the phase II component were treated 
on the phase I component of the trial (and assessed for DLT in the phase I component), 
the starting number of sequentially enrolled patients for assessment of this toxicity 
stopping boundary in the phase II component of the trial has been modified (see below 
table). When the DLT rate is unacceptably high (30%), the stopping rule has greater 
than 97% probability of early stopping. If a stopping boundary is reached, the accrual 
will be halted, and the data will be reviewed by the Moffitt Cancer Center Protocol 
Monitoring Committee.

* These stopping boundaries apply to both the MTD cohort patients from the phase I 
component that move forward to the phase II trial, as well as those patients enrolled 
initially in the phase II component of the trial 
* If these stopping boundaries are met, accrual will be suspended and the data will be 
reviewed in detail by the Protocol Monitoring Committee (PMC). The study will not be 
terminated, however. Resumption of accrual will be dictated by the review of the data by 
the study investigators and the PMC. 
 
 
VII. DATA AND SAFETY MONITORING:  
The principal investigator is obligated to report all serious adverse events (SAE) to the 
FDA, IRB, and Novartis. 
All events reported to the FDA by the investigator will be filed utilizing the Form FDA 
3500A (MedWatch Form).  
 
 
Version 7.0 
Version Date: 3.10.2016

Definition of Adverse Events: 
 
Any untoward medical occurrence in a subject or clinical investigation subject, 
temporally associated with the use of a medicinal product, whether or not considered 
related to the medicinal product. Events meeting the definition of an AE include: 
 
• 
Any abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) 
or other safety assessments e.g., ECGs, radiological scans, vital signs 
measurements), including those that worsen from baseline, and felt to be clinically 
significant in the medial and scientific judgment of the investigator 
• 
Exacerbation of a chronic or intermittent pre-existing condition including either an 
increase in frequency and/or intensity of the condition 
• 
New conditions detected or diagnosed after investigational product administration 
even though it may have been present prior to the start of the study 
• 
Signs, symptoms, or the clinical sequelae of a suspected interaction 
• 
Signs, symptoms, or the clinical sequelae of a suspected overdose of either 
investigational product or a concomitant medication (overdose per se will not be 
reported as an AE/SAE) 
 
“Lack of efficacy” or “failure of expected pharmacological action” per se will not be 
reported as an AE or SAE. However, the signs and symptoms and/or clinical sequelae 
resulting from lack of efficacy will be reported if they fulfill the definition of an AE or SAE. 
 
 
Events that do not meet the definition of an AE include: 
 
• 
Any clinically significant abnormal laboratory finding or other abnormal safety 
assessments that is associated with the underlying disease, unless judged by the 
investigator to be more severe than expected for the subject’s condition.  
• 
The disease/disorder being studied, or expected progression, signs, or symptoms of 
the disease/disorder being studied, unless more severe than expected for the 
subject’s condition 
• 
Medical or surgical procedure (e.g., endoscopy, appendectomy); the condition that 
leads to the procedure is an AE 
• 
Situations where an untoward medical occurrence did not occur (social and/or 
convenience admission to a hospital) 
• 
Anticipated day-to-day fluctuations of pre-existing disease(s) or condition(s) present 
or detected at the start of the study that do not worsen 
• 
B cell depletion and hypogammaglobulinemia due to ofatumumab treatment 
 
Version 7.0 
Version Date: 3.10.2016

Definition of Severe Adverse Events (SAE): 
A serious adverse event is any untoward medical occurrence that, at any dose: 
 
a. Results in death 
b. Is life-threatening 
NOTE:  The term 'life-threatening' in the definition of 'serious' refers to an event in 
which the subject was at risk of death at the time of the event.  It does not refer to 
an event, which hypothetically might have caused death, if it were more severe. 
 
c. Requires hospitalization or prolongation of existing hospitalization 
NOTE:  In general, hospitalization signifies that the subject has been detained 
(usually involving at least an overnight stay) at the hospital or emergency ward for 
observation and/or treatment that would not have been appropriate in the 
physician’s office or out-patient setting.  Complications that occur during 
hospitalization are AEs.  If a complication prolongs hospitalization or fulfills any 
other serious criteria, the event is serious.  When in doubt as to whether 
“hospitalization” occurred or was necessary, the AE should be considered serious. 
Hospitalization for elective treatment of a pre-existing condition that did not worsen 
from baseline is not considered an AE. 
An overnight hospital stay due to slow infusion rates will not be considered a 
Serious Adverse Event. 
 
d. Results in disability/incapacity, or 
NOTE:  The term disability means a substantial disruption of a person’s ability to 
conduct normal life functions.  This definition is not intended to include experiences 
of relatively minor medical significance such as uncomplicated headache, nausea, 
vomiting, diarrhea, influenza, and accidental trauma (e.g. sprained ankle) which 
may interfere or prevent everyday life functions but do not constitute a substantial 
disruption. 
 
e. Is a congenital anomaly/birth defect 
 
f. 
Medical or scientific judgment should be exercised in deciding whether reporting is 
appropriate in other situations, such as important medical events that may not be 
immediately life-threatening or result in death or hospitalization but may jeopardize 
the subject or may require medical or surgical intervention to prevent one of the 
other outcomes listed in the above definition.  These should also be considered 
serious.  Examples of such events are invasive or malignant cancers, intensive 
treatment in an emergency room or at home for allergic bronchospasm, blood 
 
Version 7.0 
Version Date: 3.10.2016 
40 

dyscrasias or convulsions that do not result in hospitalization, or development of 
drug dependency or drug abuse. 
g.  Laboratory and Other Safety Assessment Abnormalities Reported as AEs and 
SAEs 
• Abnormal laboratory test results (hematology, clinical chemistry, or urinalysis) or 
other safety assessments (e.g., ECGs, radiological scans, vital signs 
measurements), including those that worsen from baseline, and felt to be 
clinically significant in the medical and scientific judgment of the investigator are 
to be recorded as AEs or SAEs. 
 
• All events meeting liver stopping criteria must be recorded as an SAE.  
 
• However, any clinically significant safety assessments that are associated with 
the underlying disease, unless judged by the investigator to be more severe than 
expected for the subject’s condition, are not to be reported as AEs or SAEs. 
 
• B cell depletion, IgG below LLN, low CD19+ count, and hypogammaglobulinemia 
due to treatment with ofatumumab are not to be reported as AEs or SAEs. 
 
• Infusion related AEs may lead to a prolonged infusion time. Overnight stay at the 
hospital due to slow infusion rate is not to be reported as a SAE. 
 
 
Disease-Related Events and/or Disease-Related Outcomes Not Qualifying as 
SAEs 
An event which is part of the natural course of the disease under study (i.e., disease 
progression) does not need to be reported as an SAE.  However, if the progression of 
the underlying disease is greater than that which would normally be expected for the 
subject, or if the investigator considers that there was a causal relationship between 
treatment with investigational product or protocol design/procedures and the disease 
progression, then this must be reported as an SAE. 
 
Severity scoring and attribution of adverse events: 
As far as possible, each adverse event should be evaluated to determine: 
1.      the severity grade (mild, moderate, severe) or (grade 1-4) 
2.      its relationship to the study drug(s) (suspected/not suspected) 
3.      its duration (start and end dates or if continuing at final exam) 
4.      action taken (no action taken; study drug dosage adjusted/temporarily interrupted; 
study drug permanently discontinued due to this adverse event; concomitant medication 
taken; non-drug therapy given; hospitalization/prolonged hospitalization) 
5.      whether it constitutes a serious adverse event (SAE) 
 
 
Version 7.0 
Version Date: 3.10.2016 
41 

All adverse events should be treated appropriately. Such treatment may include 
changes in study drug treatment including possible interruption or discontinuation, 
starting or stopping concomitant treatments, changes in the frequency or nature of 
assessments, hospitalization, or any other medically required intervention. Once an 
adverse event is detected, it should be followed until its resolution, and assessment 
should be made at each visit (or more frequently, if necessary) of any changes in 
severity, the suspected relationship to the study drug, the interventions required to treat 
it, and the outcome. 
 
Collection of adverse events – study calendar driven collection schedule: 
-  
All grades (1-5) adverse events will be collected within 24 hours of start of infusion 
of ofatumumab 
- 
Grades 3-5 adverse events occurring by study day 60 must be collected, excepting 
those that are directly attributable to chronic GVHD or to relapse of the primary 
hematologic disorder 
-  
From study day 61 onward, only adverse events deemed related to the 
investigational agent ofatumumab will be collected 
 
 
Established post-transplantation complications that are anticipated, and thus will 
not inform study-related reporting of events attributable to ofatumumab from 
study day 61 onward: 
 
i. Chronic GVHD disease activity – adverse consequences of 
chronic GVHD activity itself will not be considered as adverse 
events. These are described in appendix B. 
ii. Renal or hepatic impairment related to post-transplant 
medications or complications – Renal or hepatic impairment 
temporally associated with known transplant-related insults will not 
be considered adverse events attributable to ofatumumab. 
Common examples include worsening in renal function associated 
with calcineurin inhibitors, volume depletion, or end-organ 
complications from thrombotic microangiopathy (TMA). 
iii. Electrolyte abnormalities related to post-transplant medications – 
Abnormalities in electrolytes including sodium, potassium, 
magnesium, calcium, and phosphorus are commonly observed 
following transplant, and are managed with supplementation. All 
grade electrolyte abnormalities are not considered adverse events 
attributable to ofatumumab. 
iv. Infectious complications following transplant – Infectious 
complications are frequent after transplant. Anticipated frequencies 
of infectious complications are listed in the table below (3.g.iii). 
 
Version 7.0 
Version Date: 3.10.2016 
42 

Bacterial, viral, fungal infections are anticipated, as well as 
pneumocystis jiroveci (PCP), and reactivation of cytomegalovirus 
(CMV) and Ebstein Barr virus (EBV). The frequency of infectious 
complications will be monitored during the study, and will be 
compared to historical rates. However, these will not be considered 
adverse events. 
The following table serves as a current best estimate of incidence 
of infectious complications following systemic therapy for chronic 
GVHD (reproduced from Martin, et al. Blood. 2009).19 Standard 
anti-microbial prophylaxis was delivered on this trial according to 
institutional guidelines.

vi. Hyperglycemia – This is a common occurrence in the setting of 
steroid therapy for GVHD, and is controlled with insulin or other 
medications. Therefore, this will not be reported as an adverse 
event attributable to ofatumumab. 
vii. Relapse of primary hematologic malignancy – relapse of 
malignancy is an established risk after transplant, and therefore will 
not be considered an adverse event attributable to ofatumumab.

ofatumumab.  Liver chemistries consist of ALT, AST, total bilirubin, and alkaline 
phosphatase. Patients will have liver function tests performed before study 
therapy. Study patients will have liver function tests performed at least at each 
study visit. Patients with elevated liver function tests due to chronic GVHD are 
eligible. Grade 4 hepatic toxicity attributable to ofatumumab will inform the 
determination of dose-limiting toxicity in the phase I component of the study. In the 
phase II component, ongoing monitoring of AEs will capture any grade 4 hepatic 
toxicity attributable to ofatumumab, and review of these AEs will ensure patient 
safety. 
 
Liver interruption/stopping criteria:  
 
- Liver chemistry stopping and follow up criteria has been designed to assure subject 
safety and to evaluate liver event etiology. The sponsor-investigator is to review all 
events which meet liver chemistry stopping criteria to determine if the event was due to: 
 
• tumor lysis (this is not likely in this study, as relapse of primary malignancy is an 
exclusion criterion), disease related liver involvement, or specifically hepatic 
chronic GVHD 
• concomitant chemotherapy (or other medications) 
• other identified cause and to exclude drug induced liver injury (DILI) due to 
Ofatumumab 
These criteria are relevant for Ofatumumab studies because transient elevations in 
LFTs may be due to disease related liver involvement (particularly hepatic chronic 
GVHD in this study) or due to other chemotherapy (or other medication insults) rather 
than drug induced liver injury from Ofatumumab. 
If the event is determined to be due to causes other than Ofatumumab DILI and 
improvement is observed after withdrawal of Ofatumumab, rechallenge may be 
attempted if deemed appropriate by the sponsor-investigator and in addition to consent 
of the subject.  
 
Oncology Ofatumumab Protocols Liver Interruption/Stopping Criteria: 
 
1. ALT >3 times upper limit of normal (ULN) and bilirubin >2 times ULN (>35% 
direct bilirubin; bilirubin fractionation required‡)  
2. ALT >8 times ULN 
3. ALT >5 times ULN for more than 2 weeks 
 
‡ NOTE:  If serum bilirubin fractionation not immediately available, study drug should be 
discontinued if ALT > 3xULN and bilirubin >2xULN.  Serum bilirubin fractionation should 
be performed if testing is available. If testing unavailable, record presence of detectable 
urinary bilirubin on dipstick, indicating direct bilirubin elevations and suggesting liver 
injury. 
 
Version 7.0 
Version Date: 3.10.2016 
44 

 
***NOTE: These criteria hold true for patients without LFT abnormalities before 
initiation of therapy for chronic GVHD. Thus, in these cases, new development of 
LFT abnormalities following administration of the study drug would necessarily 
prompt this evaluation. However, for patients with established LFT abnormalities 
due to chronic GVHD before initiation of study therapy, these rules will be based 
on progression of LFT abnormalities beyond these thresholds based on the pre-
therapy starting point.  
 
When any of the liver chemistry stopping criteria is met, do the following: 
 
Immediately stop study treatment 
Hold Ofatumumab for two weeks, repeat liver chemistry testing at least twice 
weekly, and report to sponsor-investigator to discuss the possibility of re-
challenging with Ofatumumab.  Medication is interrupted and it is a clinical and 
patient decision if Ofatumumab may be re-started.   
 
Report SAE to Novartis within 24 hours 
All events of ALT > 3xULN and bilirubin > 2xULN (>35% direct bilirubin) (or 
ALT>3xULN and INR>1.5, if INR measured; INR measurement is not 
required and the threshold value stated will not apply to subjects receiving 
anticoagulants), termed ‘Hy’s Law’, must be reported as an SAE 
(excluding studies of hepatic impairment or cirrhosis). 
NOTE: if serum bilirubin fractionation is not immediately available, study 
treatment should be discontinued if ALT > 3xULN and bilirubin > 2xULN. 
Serum bilirubin fractionation should be performed if testing is available. If 
testing is unavailable, record presence of detectable urinary bilirubin on 
dipstick, indicating direct bilirubin elevations and suggesting liver injury. 
 
Liver chemistry follow-up assessments are to be followed until liver chemistries resolve, 
stabilize or return to baseline values. 
Liver Chemistry Follow-up Assessments; (these chemistry tests/ assessments below 
are to be performed at the time of the event and then continued and/or discontinued at 
the discretion/judgment of the sponsor-investigator; please refer to stopping criteria

Increased  alcohol use  
The following assessments are required for subjects with ALT >3xULN and bilirubin 
>2xULN (.35% direct) but are optional for other abnormal liver chemistries:  
• 
Anti-nuclear antibody, anti-smooth muscle antibody, and Type 1 anti-liver 
kidney microsomal antibodies 
• 
Liver imaging (ultrasound, magnetic resonance, or computerized tomography) 
to evaluate liver disease.  
 
Stopping Criteria: 
• For subject meeting liver stopping criteria 1:  
o A repeat of  liver chemistries within 24 hours, liver event follow-up 
assessments and close monitoring 
o A specialist or hepatology consultation is recommended 
o Monitor subjects twice weekly until liver chemistries (ALT, AST, alkaline 
phosphatase, bilirubin) resolve, stabilize or return to within baseline 
values. 
• For subjects meeting criteria 2 or 3:  
o A repeat of  liver chemistries within 24 to 72 hours for repeat liver 
chemistries and liver event follow-up assessments  
o Monitor subjects weekly until liver chemistries (ALT, AST, alkaline 
phosphatase, bilirubin) resolve, stabilize or return to within baseline values 
• After holding Ofatumumab for two weeks:  
o If the treatment is exhibiting efficacy and the subject wants to continue 
therapy after being informed of the results of liver chemistry testing, then 
the Ofatumumab may be re-started.  
o Liver chemistries and follow-up assessments should be monitored at a 
minimum of every 2 weeks until resolution, stabilization, or a return to 
 
Version 7.0 
Version Date: 3.10.2016 
46 

baseline values, at which point monitoring should be continued per 
protocol 
• Subjects with ALT >3xULN but <5xULN and bilirubin <2xULN without hepatitis 
symptoms or rash, and who may be monitored weekly for at least 4 weeks, then 
the following actions should be taken: 
o Subjects can continue Ofatumumab 
o Weekly repeat of liver chemistries until they resolve, stabilize, or return to 
baseline values, then monitor liver chemistries as per protocol assessment 
schedule 
If at any time the subject meets any of the liver chemistry stopping criteria, then proceed 
as described above 
If after 4 weeks of monitoring, ALT<3xULN and bilirubin<2xULN monitor twice monthly 
until liver chemistries normalize or return to within baseline values 
 
b. Pregnancies:  Pregnancies must be reported to Novartis; however are not to be 
reported as SAEs unless they meet serious criteria. 
 
2. Special safety monitoring requirements on study: 
 
a. Hepatitis B Screening  
 
Follow-up monitoring must be included in the study protocol: 
• 
If HBV DNA is negative, subject may be included  
• 
Monitoring during the follow-up period will be performed during routine study 
visits for a minimum follow-up period of six months after the last dose, as long as the 
subject remains on study. Monitoring frequency during follow-up should occur at a 
minimum of every 3 months.  Whenever possible, the monitoring should occur as part of 
the routine follow-up visit  
• 
Prophylactic antiviral therapy, in addition to the monitoring described above, may 
be initiated at the discretion of the investigator. 
 
HBsAg positive (regardless of other Hepatitis B serologies): 
• exclude  
 
HBsAg negative, HBcAb negative, HBsAb positive 
• include 
 
HBsAg negative, HBcAb positive (regardless of HBsAb status) 
HBV DNA must be performed 
• if HBV DNA is positive the subject is excluded 
 
Version 7.0 
Version Date: 3.10.2016 
47 

• If HBV DNA is negative, subject may be included but must undergo at least every 
2 month HBV DNA PCR testing from the start of treatment during the treatment 
course. 
• Monitoring during the on treatment periods is required at least every 2 months 
and during follow-up at a minimum of every 2-3 months up to 6 months after the 
last dose. 
• Prophylactic antiviral therapy, in addition to the monitoring described above, may 
be initiated at the discretion of the investigator. 
 
If the subjects’ HBV DNA becomes positive during the study, the investigator should 
manage the clinical situation as per the standard of care of that institution, and the 
Novartis medical monitor should be notified. The risks and benefits of continuing 
ofatumumab or discontinuing ofatumumab should be discussed with the medical 
monitor before appropriate treatment decisions are made for that individual subject.  
 
 
b. Progressive Multifocal Leukoencephalopathy (PML) 
 
Progressive multifocal leukoencephalopathy (PML) is a viral-induced demyelinating 
disease of the central nervous system usually occurring in the immunocompromised 
individual. JC virus infection resulting in PML and death has been reported in 
rituximab-treated subjects with hematologic malignancies or with systemic lupus 
erythematosus (SLE), an indication for which rituximab has not been approved. In the 
literature, PML has been reported to occur in 0.52% of CLL subjects and in 
approximately 5% of fludarabine-treated B-CLL subjects. One case of PML was 
reported in a very ill CLL subject treated with ofatumumab, previously treated with 
alemtuzumab and fludarabine and with very low CD4 cell count. 
1. Investigators and nurses should pay careful attention for signs and symptoms 
consistent with a diagnosis of PML. Signs and symptoms of PML include visual 
disturbances, ocular movements, ataxia, and changes in mental status such as 
disorientation or confusion.  These symptoms are not an exhaustive list and the 
investigator should exercise judgment in deciding to report signs and symptoms 
to sponsor promptly. 
 
2. If a subject develops neurological signs or symptoms consistent with PML 
treatment should be halted and the subject referred to a neurologist for 
evaluation.  At a minimum, blood JCV PCR and/or MRI will be performed and if 
either is positive perform Cerebrospinal Fluid (CSF) JCV PCR. If blood JCV PCR 
and MRI are negative, the investigator will contact the Novartis for appropriate 
action to be taken. If blood JCV PCR and/or MRI are positive, the subject should 
proceed to the Follow-Up Period. All such subjects will be followed until 
resolution.  Any subject with a diagnosis of PML will be withdrawn from 
ofatumumab. There are no known tests that can reliably determine who is at 
increased risk for developing PML. There are no known interventions that can 
reliably prevent PML or adequately treat PML if it occurs.

SAE Reporting Procedures: 
The study PI will have primary responsibility to rapidly communicate SAE to the 
monitoring agencies as follows: 
 
NOVARTIS:  
Once an investigator determines that an event meets the protocol definition of an SAE, 
the SAE will be reported to Novartis within 24 hours of being notified of the event.  All 
SAEs regardless of relationship to investigational product will be collected from the first 
dose of investigational product up to a minimum of 6 months after the last dose of 
investigational product or until the end of the follow-up period whichever is longer. All 
SAEs regardless of causality will be collected until the end of the follow-up period.  
SAEs are no longer required to be reported if a subject begins treatment with another 
therapy. From the time a subject consents to participate in and completes the study all 
SAEs assessed as related to study participation (e.g., protocol-mandated 
procedures, invasive tests, or change in existing therapy) or related to Novartis 
concomitant medication, will be reported promptly to Novartis. 
 
Any SAE brought to the investigator’s attention after the subject has completed the 
study and considered by the investigator as possibly related to investigational product 
must be reported to Novartis. 
 
Pregnancy 
Any pregnancy that occurs during study participation must be reported to Novartis.   To 
ensure subject safety, each pregnancy must be reported to Novartis within 2 weeks of 
learning of its occurrence.  The pregnancy must be followed up to determine outcome 
(including premature termination) and status of mother and child.  Pregnancy 
complications and elective terminations for medical reasons must be reported as an AE 
or SAE.  Spontaneous abortions must be reported as an SAE. Any SAE occurring in 
association with a pregnancy, brought to the investigator’s attention after the subject 
has completed the study and considered by the investigator as possibly related to the 
investigational product, must be promptly reported to Novartis. In addition, the 
investigator must attempt to collect pregnancy information on any female partners of 
male study subjects who become pregnant while the subject is enrolled in the study. 
Pregnancy information must be reported to Novartis as described above. 
All SAEs will be reported to Novartis within 24 hours of the PI being notified of the SAE. 
The following represents the contact information for this reporting: 
Report SAE Information to Novartis via Fax to: 
U.S. Drug Safety & Epidemiology: Fax # 877-778-9739 
 
Should the designated SAE Fax# be non-functional please send SAEs to the 
designated SAE mailbox: clinicalsafetyop.phuseh@novartis.com 
 
 
Version 7.0 
Version Date: 3.10.2016 
50 

Novartis SAE Fax Coversheet must be attached to the SAE Submission 
 
SAE submissions must reference Novartis Study Code: COMB157EUS03T 
 
University of South Florida IRB: 
  
Unanticipated problems that are serious adverse events should be reported to the IRB 
immediately of the investigator becoming aware of the event.  
 
Any other unanticipated problem involving risks to subjects or others should be reported 
to the IRB immediately of the investigator becoming aware of the problem.  
 
All unanticipated problems should be reported to appropriate institutional officials (as 
required by an institutions written reporting procedures), the supporting agency head (or 
designee), and OHRP within one month of the IRB’s receipt of the report of the problem 
from the investigator.  
 
For device studies, investigators are required to submit a report of a UADE to the 
sponsor and the reviewing IRB as soon as possible, but in no event later than 10 
working days after the investigator first learns of the event (§ 812.150(a)(1)).  
 
FDA: 
IND Safety Reporting Requirements 
This protocol is associated with an Investigational New Drug Application (“IND”) 
sponsored by Dr. Joseph Pidala at Moffitt Cancer Center.  IND Safety Reports are 
required for any adverse experience associated (or possibly associated) with the use of 
the investigational product(s) that is both serious and unexpected. To meet the IND 
Safety Reporting requirements set forth in 21 CFR §312.32,  FDA Form 3500A 
(MedWatch form) will be completed and provided to the Moffitt Office of Institutional 
Regulatory Affairs for Investigational Drugs and Devices. All other adverse events will 
be reported to the FDA as part of the annual reporting requirement of the IND. 
The initial report will be as complete as possible, including details of the current illness 
and serious adverse event, and an assessment of the causal relationship between the 
event and the investigational product(s). Information not available at the time of the 
initial report (e.g., an end date for the adverse event or laboratory values received after 
the report) will be documented on a follow-up report. A final report to document 
resolution of the serious adverse event is required if it is not documented in the initial 
report. 
The Moffitt Office of Institutional Regulatory Affairs will complete the necessary 
documents and provide the report to the FDA as an official submission to the IND. This 
will occur independently of any other use of the MedWatch form or required reporting of 
serious adverse events.  Submission of the MedWatch form to any other agency, 
including the FDA, does not fulfill this IND Safety Reporting requirement.  Follow-up to 
 
Version 7.0 
Version Date: 3.10.2016 
51 

the safety report must also be submitted to the Office of Institutional Regulatory Affairs 
in a timely manner.   
Upon completion of the report, a copy of all initial and follow-up MedWatch forms will be 
FAXed to the Manager of the Office of Institutional Regulatory Affairs (813-745-8332) 
and a telephone call or email will be made to confirm receipt. 
For unexpected fatal or life threatening experiences associated with the use of the 
investigational product(s), the Office of Institutional Regulatory Affairs will be contacted 
within 24 hours. Notification to the FDA will be made as soon as possible, but no later 
than 7 calendar days after initial receipt of the information. 
 
Data Safety and Monitoring Plan  
The Data Safety & Monitoring Plan (DSMP) will ensure that this trial is well designed, 
responsibly managed, appropriately reported, and that it protects the rights and welfare 
of patients. The following internal and external review and monitoring processes provide 
oversight and active monitoring of this trial:  
 
 
• The Principal Investigators (PI)  
• The Scientific Review Committee (SRC)  
• The Protocol Monitoring Committee (PMC) 
• The Research Compliance Division of the Cancer Center’s Compliance Office 
(RCD) 
• Institutional Review Board (IRB)  
 
The protocol includes what constitutes an adverse event (versus what is a serious 
adverse event), the entities to which adverse events should be reported, the timing of 
this reporting, and the person or persons responsible for reporting.   
 
Initial and Ongoing Monitoring and Review  
Principal Investigator (PI)  
The PI of the study has primary responsibility for ensuring that the protocol is conducted 
as approved by the SRC and the IRB. The PI will review weekly with the trial 
coordinator patient eligibility and accrual. The PI will continuously monitor data both for 
efficacy and toxicity through weekly meetings conducted together with the clinical trial 
coordinator, and in monthly review of data in the Moffitt BMT Program research 
meeting. The PI will also be responsible for monitoring recorded data for accuracy 
through review of primary clinical records. The PI will ensure that the monitoring plan is 
followed, that all data required for oversight of monitoring are accurately reported to the 
Scientific Review Committee (SRC), Protocol Monitoring Committee (PMC) and IRB as 
required, and that all adverse events are appropriately reported.  
 
 
Version 7.0 
Version Date: 3.10.2016

The Scientific Review Committee (SRC)  
The Cancer Center's internal Scientific Review Committee (SRC) provides for a formal 
internal peer review of all protocols and general scientific oversight of interventional 
clinical research. The Committee has a defined membership representing all of the 
major research divisions of the Cancer Center, including biostatisticians. All new 
protocol submissions must contain the required elements of the protocol, and must 
includes a DSMP prior to approval by the Committee. The plan has to be appropriate for 
the phase and risk of the proposed study.  
 
The Protocol Monitoring Committee (PMC)  
The Protocol Monitoring Committee (PMC) will monitor this trial for safety, progress, 
protocol compliance, accrual, adverse event reporting, and data integrity. The 
membership of the PMC includes physician representation from each program area and 
a biostatistician. In addition to the existing stopping rules, the PMC is authorized to 
suspend a trial for non-compliance with a DSMP or as a result of audit findings deemed 
unacceptable. The PMC will report significant findings to the IRB, and applicable 
regulatory bodies. Interim meetings are scheduled to address specific issues that 
require immediate attention to ensure safety of research participants.  
 
Phase I:  Safety and monitoring reports are to be submitted to the Protocol Monitoring 
Committee (PMC) after completing each odd numbered dose level (i.e., 1, 3, 5, etc), or 
more frequently if requested by the PMC.  A final safety and monitoring report must be 
submitted to the PMC within three months of defining the maximum tolerated dose 
(MTD).     
Phase II:  Safety and monitoring reports are to be submitted to the Protocol Monitoring 
Committee (PMC) once 30% of the total accrual has been met or once the early 
stopping rule threshold has been met.  A final safety and monitoring report must be 
submitted to the PMC within three months of last subject enrollment.  
 
The Research Compliance Division of the Cancer Center’s Compliance Office 
(RCD) 
The Cancer Center’s Research Compliance Division (RCD) of the Corporate 
Compliance Department coordinates internal audits of all investigator-initiated trials 
conducted at the Cancer Center and its affiliates. The frequency of the audits is driven 
by the rate of accrual on a specific trial as well as the perceived patient risk for 
participating in the trial.  Internal audits are conducted by the RCD in accordance with 
applicable regulatory standards.  
 
 The purpose of the internal audit program is to: 
• Ensure protocol compliance and the validity and integrity of data, thereby promoting 
patient safety and maintaining scientific validity 
• Recommend modification of research practices as necessary and provide education 
on issues that are critical to good research practices 
 
Version 7.0 
Version Date: 3.10.2016

The following elements of trial documentation may be incorporated into this review: 
• Source documentation verification of eligibility and compliance with the protocol 
• Compliance with adverse and serious adverse event reporting standards 
• Regulatory review of IRB compliance and external reporting requirements 
• Drug/device accountability and handling 
• Completeness and quality of data 
 
RCD auditors report findings to the PI and PMC, as appropriate, for review and audit 
determinations along with a statement from the PI. The PI is encouraged to proactively 
implement corrective actions to remedy any deficiencies noted in the audit. The PMC 
determines the findings as one of the following: Acceptable, Acceptable with corrective 
action, Tabled for Additional Information, or Unacceptable. The PI and IRB are then 
informed of the audit determinations made by the PMC. The PI and IRB are then 
informed of the audit determinations made by the PMC. Audit results may then be 
presented to the Corporate Compliance Steering Committee, chaired by the Center 
Director, and to the Joint Corporate Compliance Committee of the Board  
 
Trial monitoring by Moffitt Monitoring Core (MMC) 
Trial monitoring by the Moffitt Monitoring Core (MMC) will verify that the rights and 
wellbeing of human subjects enrolled in specific Moffitt sponsored principal investigator 
(PI) initiated clinical research are protected. PI initiated clinical trials will be monitored 
on-site regularly to verify the reported trial data is accurate, complete, and verifiable 
from source documents; and the conduct of the trial is in compliance with the currently 
approved protocol/amendments, data safety-monitoring, Good Clinical Practice (GCP), 
and applicable regulatory requirements.  Routine monitoring visits will be conducted, at 
a minimum, annually. 
 
Institutional Review Board (IRB) 
The trial will not be initiated without approval of the appropriate Institutional Review 
Board (IRB).  All administrative requirements of the governing body of the institution will 
be fully complied with.  This protocol, consent procedures, and any amendments will be 
approved by the IRB in compliance with current regulations of the Food and Drug 
Administration prior to initiation unless necessary to protect the safety and welfare of 
subjects; in which case, the IRB will be notified within 24 hours of implementing the 
change.  The IRB will be kept informed by the investigator as to the progress of the 
study as well as to any serious or unusual adverse events. 
 
Protocol amendments or changes in study conduct  
Any change or addition (excluding administrative) to this protocol requires a written 
protocol amendment that will be reviewed and approved by the Moffitt Cancer Center 
SRC and the Institutional Review Board (IRB).

Data management  
Data collection  
Investigators must enter the information required by the protocol onto Case Report 
Forms (CRFs).  
 
Records to be kept  
Data will be kept confidential and will be entered into Oncore and the BMT research 
database. In computer generated reports for external review, patients will only be 
referred to by a unique identification number.  
Both Oncore and the BMT research database is password protected and limited only to 
designated personnel. In order to assure quality, both physicians and clinical research 
personnel regularly audit specified data that is manually entered into the system.  
Representatives of the IRB, the FDA, and other governmental regulatory authorities will 
have access to patient information as it pertains to the study. Privacy and confidentiality 
of the information will be protected to the extent provided by law.  
 
Ethics and Good Clinical Practice  
This study will be carried out in compliance with the protocol and the principles of Good 
Clinical Practice, as described in:  
• ICH Harmonized Tripartite Guidelines for Good Clinical Practice 1996. Directive 
91/507/EEC, The Rules Governing Medicinal Products in the European 
Community.  
• US 21 Code of Federal Regulations dealing with clinical studies (including parts 
50 and 56 concerning informed consent and IRB regulations).  
• Declaration of Helsinki and amendments, concerning medical research in 
humans (Recommendations Guiding Physicians in Biomedical Research 
Involving Human Subjects).  
The investigator agrees to adhere to the instructions and procedures described in it and 
thereby to adhere to the principles of Good Clinical Practice that it conforms to.  
 
Informed consent  
The investigator and/or designated members of the research study team will explain to 
each subject the nature of the study, its purpose, the procedures involved, the expected 
duration, the potential risks and benefits involved and any discomfort it may entail. Each 
subject will be informed that participation in the study is voluntary and that he/she may 
withdraw from the study at any time and that withdrawal of consent will not affect his/her 
subsequent medical treatment or relationship with the treating physician.  
This informed consent will be given by means of a standard written statement, written in 
non-technical language. The subject will read and consider the statement before signing 
 
Version 7.0 
Version Date: 3.10.2016

Global assessment score for chronic GVHD 
 
a. Mild chronic GVHD 
i. Involves only 1 or 2 organs or sites (except lung) with no clinically 
significant functional impairment (maximum score of 1 in all 
affected organs or sites. 
 
b. Moderate chronic GVHD 
i. Involves at least 1 organ or site with clinically significant but no 
major disability (maximum score of 2 in any affected organ or site) 
ii. Or, 3 or more organs or sites with no clinically significant functional 
impairment (maximum score of 1 in all affected organs or sites).

1. A score of 1 involving the lung is also considered moderate 
chronic GVHD 
 
c. Severe chronic GVHD 
i. Major disability caused by chronic GVHD (score of 3 in any organ 
or site) 
ii. Lung score of 2 or greater also considered chronic GVHD

*Enrollment may occur within 14 days of initiation of prednisone for chronic GVHD.  Screening tests may 
occur between start of prednisone and ofatumumab. 
*As the MTD will not be known in real-time, patients on any of the phase I dose levels may potentially be 
those carried forward from the MTD cohort as the recommended phase II dose. Accordingly, patients in 
all dose levels of the phase I trial will need to have all of the above outlined on-study assessments 
performed until the MTD is defined. Once the MTD is defined, only those patients in the MTD cohort will 
continue to have all of the ongoing assessments performed. Conversely, those in the non-MTD cohorts 
will complete an abbreviated assessment measure set to include only the chronic GVHD activity 
assessments/response determination and the biologic studies (B cell subsets, BAFF levels) at 6 and 12 
month time points. These limited assessments for the non-MTD dose level patients will be included to 
examine the relationship between dose and clinical response, and dose/pharmacodynamic activity. 
**Schirmer test can be done as needed for supportive information in diagnosis of ocular sicca, however is 
not required by the trial, and does not need to be done on serial visits
