PROTOCOL TITLE: An Open-Label Phase 2 Study of Ofatumumab (Arzerra) in 
Combination with Oral GSK2110183 in the Treatment of Relapsed and Refractory Chronic 
Lymphocytic Leukemia (CLL) 
DATE PROTOCOL FINAL:  
June 6, 2011 
INDICATION:  
Relapsed or refractory CLL, previously treated 
with at least one fludarabine-containing regimen 
STUDY PHASE:  
Phase II 
 
 
BACKGROUND AND RATIONALE: 
 
Ofatumumab is a novel anti-CD20 monoclonal antibody with promising anti-tumor activity in 
CLL.  In an international study of heavily pretreated CLL patients either refractory to both 
fludarabine and alemtuzumab (FA-ref) or refractory to fludarabine with bulky nodal disease (BF-
ref), ofatumumab led to impressive single-agent response rates of 58% (FA-ref) and 47% (BF-ref) 
(Wierda 2010).  In this study, toxicities were predictable and significant myelosuppression was 
uncommon (grade 3-4 neutropenia 6-14%).  Although responses were rapid in onset (80% of 
responses occurring within 2 months), response durations were relatively short at a median of 7.1 
months (FA-ref) and 5.6 months (BF-ref).  Based on results from this study, ofatumumab 
received FDA approval for treatment of FA-ref patients with CLL.  However, despite these 
encouraging preliminary data of single-agent ofatumumab, improvements in response rates, 
quality and duration of responses, will likely only be achieved with combination therapy.    
 
GSK2110183 is a novel pan-AKT kinase inhibitor that potently inhibits growth in vitro of 
numerous hematologic cell lines, including CLL.  The AKT pathway plays a centralized role in 
tumor differentiation, migration, proliferation and survival.  Aberrant activation of the AKT 
pathway is frequently observed in CLL and may be associated with chemotherapy resistance and 
a higher capacity for proliferation (Longo 2007).  AKT inhibition appears to cause CLL cell 
apoptosis primarily via effects on the microenvironment, such as counteracting the protective 
anti-apoptotic effect of stromal cells (Shehata 2010).  Importantly, AKT inhibition in primary 
CLL samples leads to apoptosis of CLL B cells with preferential sensitivity of cells with high-risk 
features of unmutated IgVH status and CD38 positivity (Hofbauer 2010).  In fludarabine-resistant 
samples with 17p13 deletion, AKT inhibition can lead to clear apoptosis, similar to that seen in 
fludarabine-sensitive samples.  In an ongoing phase 1-2 trial of single agent GSK2110183 in 
relapsed and refractory patients with various hematologic malignancies, this oral agent was found 
to be very well-tolerated with minimal myelotoxicity. Dose-limiting toxicities in the phase 1 part 
were reversible liver enzyme abnormalities.  The phase 2 part is ongoing and has thus far shown 
encouraging responses in myeloma and other lymphoproliferative disorders, including CLL.   
 
The combination of ofatumumab and GSK2110183 is attractive for use in relapsed and refractory 
CLL as these two agents have markedly different mechanisms of action, non-overlapping 
toxicities, and activity in resistant disease.  We propose the use of this combination in patients 
with CLL who have relapsed or are refractory to prior fludarabine-based therapy (single agent or 
combination therapy), with or without bulky nodal disease. The dose and schedule of 
ofatumumab will be identical to that used in the pivotal trial of single-agent ofatumumab and the 

PMH-GSK2110183-CLL001 
Confidential 
Page 9 of 68  
 
Version 8: 22 May 2014 
daily recommended phase 2 dose of GSK2110183 will be used. As neither ofatumumab nor 
GSK2110183 are myelosuppressive, the combination is anticipated to be well-tolerated in a 
relapsed or refractory CLL population where cytopenias are common.  Currently, neither 
ofatumumab nor GSK2110183 are available for use in Canada.  Although rituximab is approved 
for first line use as part of the FCR (fludarabine, cyclophosphamide, rituximab) regimen, 
retreatment using rituximab is not available.  Furthermore, access to alemtuzumab in Ontario is 
restricted (no funding) and rarely available.  As a result, there are limited options for therapy in 
CLL patients failing fludarabine therapy in Ontario and there is heavy demand from community 
oncologists and patients for clinical trials that provide novel therapies.  Currently at Princess 
Margaret Cancer Centre, the largest tertiary care oncology centre in Canada, we have no 
competing trials for CLL patients who are relapsed or refractory to prior fludarabine-based 
therapy, and therefore accrual to this proposed study is anticipated to be rapid and efficient. 
 
STUDY OBJECTIVES: 
Primary:   
1. To assess the efficacy (overall response rate, including complete and partial responses as 
per the IWCLL 2008 response criteria) of ofatumumab in combination with 
GSK2110183 in the treatment of patients with relapsed or refractory CLL who have 
received at least one prior fludarabine-containing regimen.  
Secondary: 
1. To assess the toxicity of ofatumumab in combination with GSK2110183 in patients with 
relapsed or refractory CLL. 
2. To assess clinical efficacy endpoints such as progression-free and overall survival, stable 
disease, response duration, and time to next CLL therapy following therapy with 
ofatumumab in combination with GSK2110183. 
3. To identify predictors of response using gene expression analysis and demonstrate target 
inhibition via flow-cytometry based pharmacodynamic studies.  
4. To evaluate the pharmacokinetics of GSK2110183 after multiple single agent daily 
dosing and in combination with ofatumumab in first 10 eligible participants. 
 
STUDY DESIGN: 
This is a phase 2, open-label, single institution trial of combination of intravenous (IV) 
ofatumumab and oral GSK2110183 in patients with relapsed or refractory CLL.  Patients must 
have received at least one prior line of therapy containing fludarabine (single-agent or 
combination therapy).  During the initial 7 months Treatment Phase, ofatumumab will be 
administered weekly for 8 doses, then once every 4 week cycle for an additional 4 doses (dose 
and schedule identical to the pivotal phase 2 trial) (Wierda 2010) and GSK2110183 will be given 
daily PO (Treatment Phase).  There will be an initial 10 day lead-in with GSK2110183 alone 
prior to initiation of ofatumumab to allow for evaluation of changes in cell surface expression due 
to GSK2110183 and for GSK2110183 pharmacokinetic studies (Lead-in Phase).  The official 
Cycle 1 Day 1 will start on the date of first dose of ofatumumab.  Cycle duration = 4 weeks.  
Patients will be assessed for safety, disease assessment, response, and survival on day 1 of each 
cycle during the Treatment Phase. The safety data will be reviewed by the Data Safety 
Monitoring Board (DSMB) during their biannual meeting. Enrollment will continue while DSMB 
response to the review of the safety data is awaited. All patients achieving SD, PR or CR by the 
end of the Treatment Phase will proceed to the Maintenance Phase. Patients with PD at any time, 
including by the end of Treatment Phase, will be taken off study.  During the Maintenance Phase, 

PMH-GSK2110183-CLL001 
Confidential 
Page 10 of 68  
 
Version 8: 22 May 2014 
single-agent GSK2110183 will be administered daily for a maximum of 12 months (12 cycles).  
Maximum duration on any study drug is 18 months (18 cycles).  During the Follow-up Phase, 
patients will be assessed for safety, disease assessment, response, and survival every 3 months 
through month 36 (year 3), or until subsequent CLL therapy or death, whichever comes first.  
Key indications for study withdrawal are progressive disease, intolerable toxicity, or completion 
of therapy.

* An unscheduled visit can occur at any time during the study.  The date for the visit and any data generated must be recorded on the appropriate CRF.  Source documents for 
these unscheduled visits must also be maintained. 
* Scheduled visits will have window period of +/- 4 days. 
 
1. During the ofatumumab infusion, vital signs will be obtained preinfusion, at 30-minute intervals for the first hour during ofatumumab infusion, and then every 
hour until completion of infusion, including postinfusion.  More frequent vital sign measurements should be performed if unstable, or if adverse events occur. 
2. Bone marrow aspirate and biopsy to be performed routinely at baseline screening and at study discontinuation for morphology.  BM aspirate samples (no 
biopsy) will be taken for correlatives at baseline screening and at study discontinuation (only if patient is progressing at time of study discontinuation).  An 
additional bone marrow aspirate (no biopsy) will be performed on Day 8 of the lead-in phase (Window period of + 2 days to coincide with clinic days) for 
correlative studies only. Repeat bone marrows at any other time will only be performed to confirm CR. 
3. All patients with baseline abnormalities on CT will undergo rescanning at end of cycle 6 (prior to the start of the Maintenance Phase), at study discontinuation, 
and to assess CR only.  CT scans will not be performed routinely to assess partial response at any other time unless required at investigator discretion.  Total 
estimated radiation per patient completing the study: 3-4.5 cGY (mSv)

3 Background and Rationale 
3.1 Introduction 
Ofatumumab is a novel anti-CD20 monoclonal antibody with promising anti-tumor activity in CLL.  
In an international study of heavily pretreated CLL patients either refractory to both fludarabine and 
alemtuzumab (FA-ref) or refractory to fludarabine with bulky nodal disease (BF-ref), ofatumumab 
led to impressive single-agent response rates of 58% (FA-ref) and 47% (BF-ref)(Wierda et al. 2010).  
In this study, toxicities were predictable and significant myelosuppression was uncommon (grade 3-4 
neutropenia 6-14%).  Although responses were rapid in onset (80% of responses occurring within 2 
months), response durations were relatively short at a median of 7.1 months (FA-ref) and 5.6 months 
(BF-ref).  Based on results from this study, ofatumumab received FDA approval for treatment of FA-
ref patients with CLL. However, despite these encouraging preliminary data of single-agent 
ofatumumab, improvements in response rates, quality and duration of responses, will likely only be 
achieved with combination therapy.    
 
GSK2110183 is a novel pan-AKT kinase inhibitor that potently inhibits growth in vitro; of numerous 
hematologic cell lines, including CLL. The AKT pathway plays a centralized role in tumor 
differentiation, migration, proliferation and survival.  Aberrant activation of the AKT pathway is 
frequently observed in CLL and may be associated with chemotherapy resistance and a higher 
capacity for proliferation (Longo et al. 2007).  AKT inhibition appears to cause CLL cell apoptosis 
primarily via effects on the microenvironment, such as counteracting the protective anti-apoptotic 
effect of stromal cells (Shehata et al. 2010).  Importantly, AKT inhibition in primary CLL samples 
leads to apoptosis of CLL B cells with preferential sensitivity of cells with high-risk features of 
unmutated IgVH status and CD38 positivity (Hofbauer et al. 2010).  In fludarabine-resistant samples 
with 17p13 deletion, AKT inhibition can lead to clear apoptosis, similar to that seen in fludarabine-
sensitive samples.  In an ongoing phase 1-2 trial of single agent GSK2110183 in relapsed and 
refractory patients with various hematologic malignancies, this oral agent was found to be very well-
tolerated with minimal myelotoxicity.  Dose-limiting toxicities in the phase 1 part were reversible 
liver enzyme abnormalities.  The phase 2 part is ongoing and has so far shown encouraging 
responses in myeloma and other lymphoproliferative disorders, including CLL.

3.2 Rationale for Treatment in Chronic Lymphocytic Leukemia  
3.2.1 Clinical study rationale: 
 
The combination of ofatumumab and GSK2110183 is attractive for use in relapsed and refractory 
CLL as these two agents have markedly different mechanisms of action, non-overlapping toxicities, 
and activity in resistant disease.  We propose the use of this combination in patients with CLL who 
have relapsed or are refractory to prior fludarabine-based therapy (single agent or combination 
therapy), with or without bulky nodal disease.  The dose and schedule of ofatumumab will be 
identical to that used in the pivotal trial of single-agent ofatumumab and the daily recommended 
phase 2 dose of GSK2110183 will be used. As neither ofatumumab nor GSK2110183 are 
myelosuppressive, the combination is anticipated to be well-tolerated in a relapsed or refractory CLL 
population where cytopenias are common.  Currently, neither ofatumumab nor GSK2110183 are 
available for use in Canada.  Although rituximab is approved for first line use as part of the FCR 
(fludarabine, cyclophosphamide, rituximab) regimen, retreatment using rituximab is not available.  
Furthermore, access to alemtuzumab in Ontario is restricted (no funding) and rarely available.  As a 
result, there are limited options for therapy in CLL patients failing fludarabine therapy in Ontario and 
there is heavy demand from community oncologists and patients for clinical trials that provide novel 
therapies.  Currently at Princess Margaret Cancer Centre, the largest tertiary care oncology centre in 
Canada, we have no competing trials for CLL patients who are relapsed or refractory to prior 
fludarabine-based therapy, and therefore accrual to this proposed study is anticipated to be rapid and 
efficient. 
 
3.2.2 Correlative studies rationale: 
As a companion study to the proposed clinical trial, we will conduct experiments aimed at 
identifying predictors of response and pharmacodynamic studies to demonstrate target inhibition. 
Pharmacokinetic studies will be analyzed after multiple dosing of GSK2110183 alone and during 
combination GSK2110183 and ofatumumab to determine interactions in plasma levels of the two 
agents.  See Appendix 6 for details of PD and PK studies.

4 Study Objectives and Endpoints 
4.1 Objectives 
4.1.1 Primary objectives 
 To assess the efficacy (overall response rate, including complete and partial responses as per 
the IWCLL 2008 response criteria) of ofatumumab in combination with GSK2110183 in the 
treatment of patients with relapsed or refractory CLL who have received at least one prior 
fludarabine-containing regimen  
4.1.2 Secondary study objectives 
 To assess the toxicity of ofatumumab in combination with GSK2110183 in patients with 
relapsed or refractory CLL 
 To assess clinical efficacy endpoints such as progression-free and overall survival, stable 
disease, response duration, and time to next CLL therapy following therapy with ofatumumab 
in combination with GSK2110183.  
 To identify predictors of response using gene expression analysis and demonstrate target 
inhibition via flow-cytometry based pharmacodynamic studies (Appendix 6) 
 To evaluate the pharmacokinetics of GSK2110183 after multiple single agent daily dosing 
and in combination with ofatumumab in first 10 eligible participants. (Appendix 6) 
4.2 Endpoints 
4.2.1 Primary Endpoint 
 Overall response rate (includes partial and complete responses) 
4.2.2 Secondary Endpoints 
 Stable disease duration, and if responses are observed, response duration, progression-free 
and overall survival. 
 Safety (type, frequency, severity, and relationship of adverse events to study therapy). 
5 Investigational Plan 
5.1 Overall design 
This is a phase 2, open-label, single institution trial of combination IV ofatumumab and oral 
GSK2110183 in patients with relapsed or refractory CLL.  During the initial 7 months Treatment

Page 17 of 68  
 
Version 8: 22 May 2014 
 
 
 
Phase, ofatumumab will be administered weekly for 8 doses, then once every 4 weeks cycle for an 
additional 4 doses (dose and schedule identical to the pivotal phase 2 trial, Wierda et al. 2010)  and 
GSK2110183 will be given daily PO (Treatment Phase).  There will be an initial 10 day lead-in with 
GSK2110183 alone prior to initiation of ofatumumab to allow for evaluation of changes in cell 
surface expression due to GSK2110183 and pharmacokinetic studies (Lead-in Phase).  The official 
Cycle 1 Day 1 will start on the date of first dose of ofatumumab.  Cycle duration = 4 weeks.  Patients 
will be assessed for safety, disease assessment, response, and survival on day 1 of each cycle during 
the Treatment Phase.  The safety data will be reviewed by the DSMB during their biannual meeting. 
Enrollment will continue while DSMB response to the review of the safety data is awaited. All 
patients achieving SD, PR or CR by the end of the Treatment Phase will proceed to the Maintenance 
Phase. Patients with PD at any time, including by the end of Treatment Phase, will be taken off 
study.  During the Maintenance Phase, single-agent GSK2110183 will be administered daily for a 
maximum of 11 months (11 cycles).  Maximum duration on any study drug is 18 months (18 cycles).  
During the Follow-up Phase, patients will be assessed for safety, disease assessment, response, and 
survival every 3 months through month 36 (year 3), or until subsequent CLL therapy or death, 
whichever comes first.  Key indications for study withdrawal are progressive disease, intolerable 
toxicity or completion of therapy.

5.1.1 Investigational Drug - Ofatumumab 
Ofatumumab is a fully human monoclonal antibody (mAb), IgG1κ, targeting a unique CD20 epitope, 
resulting in increased binding affinity to CD20, prolonged dissociation rate and increased ability to 
bind and activate complement (C1q) at the cell surface. This generates a superior induction of tumor 
cell lysis by CDC activity, especially in cells with low CD20 density, as it is the case in CLL, with 
similar ADCC activity, compared to tumor cell lysis capability observed with rituximab (Teeling et al 
2006). 
 
In a phase I dose-ranging trial of ofatumumab 500mg (n=3), 1000mg (n=3), and 2000mg (n=27) 
given weekly x 4, 50% PR was observed with the highest dose amongst relapsed CLL patients. 
(Coiffier et al. 2008).  Cmax, Cmin, AUC and t½ increased from dose 1 to 4 in all three arms. In the 
2000mg dose group, objective response significantly correlated with Cmax, AUC and t½ after dose 4 
and survival endpoints correlated with exposure. The MTD (maximum tolerated dose) was not 
reached and treatment was well tolerated. Adverse events were limited to grade 1-2 infusion 
reactions, grade 3-4 neutropenia occurred in only 6% of patients and non-opportunistic grade 1-2 
infections were observed in 51% of patients. 
 
A phase II study of 500mg and 1000mg ofatumumab in combination with fludarabine and 
cyclophosphamide (OFC) in frontline CLL patients is ongoing. 
 
The investigational medical product, ofatumumab, is a liquid concentrate for solution for infusion 
presented in glass vials. Ofatumumab will be infused intravenously on day 1 (300mg) followed by an 
infusion of 2000 mg weekly for 7 doses, followed 4 weeks later by an infusion of 2000 mg every 4 
weeks for 4 additional doses.  Each cycle will be of 4 weeks in duration. 
 
The ofatumumab infusions will be prepared in 1000mL sterile, pyrogen free 0.9% NaCl to yield a 
0.3mg/mL and 2mg/mL ofatumumab concentration for the first and subsequent infusions, 
respectively.

5.1.2 GSK2110183 
GSK2110183 is a novel member of the N-alkyl pyrazole class of orally available kinase inhibitors 
and has been shown to be a potent, pan-AKT inhibitor, with potency (Ki*) values for AKT 1, 2 and 3 
kinases being 0.084, 2.0 and 2.6 nM, respectively.  GSK2110183 exhibits a time-dependent inhibition 
of AKT with a dissociation half-life of 20 minutes. In vitro, GSK2110183 causes a concentration- and 
time-dependent reduction in phosphorylation of multiple proteins downstream of AKT such as GSK3, 
PRAS40, Forkhead (FOXO1/3a) and Caspase 9. Treatment of tumor cells with GSK2110183 resulted 
in a concentration-dependent increase in the nuclear translocation of the FOXO-3a transcription 
factor as a functional consequence of reduced phosphorylation of FOXO-3a. GSK2110183 has been 
shown to inhibit the proliferation of a range of tumor cell lines from multiple histologies including 
breast, hematological, colon, ovarian and prostate (EC50 <1 uM). AKT signaling is inhibited in cell 
lines both sensitive and less sensitive to GSK2110183, suggesting that resistance to GSK2110183 is 
not due to a lack of AKT kinase inhibition. GSK2110183 has been shown to induce cycle arrest at G1 
phase or apoptosis in a concentration-dependent manner depending on the cellular context. 
 
GSK2110183 is an oral, low nanomolar pan-AKT kinase inhibitor given once daily in a phase 1, 
first-time-in-human (FTIH), two-stage study of patients with various hematologic malignancies.  
This study identified the maximal tolerated dose as 125mg daily with a cohort expansion Part 2 at 
this dose.   The most common adverse events (AEs) were GI disorders (nausea 35%, dyspepsia 35%, 
diarrhea 19%, vomiting 12%) with very few drug-related Grade 3 AEs.  The most frequent Grade 3 
AEs were liver function test abnormalities (AST and ALT).  Myelosuppression is uncommon at the 
125mg dose (Grade 3-4 neutropenia 13%).  Although AKT2 is an integral part of the insulin 
signaling pathway and hyperglycemia and hyperinsulinemia may be expected, no clinically 
significant hyperglycemia was observed in this study.  Since GSK2110183 inhibits multiple 
cytochrome P450 (CYP) enzymes in vitro, there is potential for significant drug-drug interactions 
and therefore a variety of agents are prohibited or are to be used with caution during GSK2110183 
use. 
 
Four strengths of GSK2110183 (hydrochloride salt), formulated as a white to almost white solid, are 
provided as capsules equivalent to 1, 5, 25 or 100mg of GSK2110183 (free form).

investigator. 
 
During the ofatumumab infusion the patient should be monitored closely.  Vital signs will be 
obtained preinfusion, at 30-minute intervals for the first hour during ofatumumab infusion, and then 
every hour until completion of infusion, including post-infusion.  More frequent vital sign 
measurements should be performed if unstable, or if adverse events occur. 
 
First Infusion of 300 mg Ofatumumab (CLL) 
The first dose administered of ofatumumab in CLL should be 300 mg to minimize infusion reactions. 
The initial rate of the first infusion of 300 mg ofatumumab (0.3 mg/mL) should be 12 mL/h. If no 
infusion reactions occur the infusion rate should be increased every 30 minutes, to a maximum of 
400 mL/h, according to Table 2. If this schedule is followed, the infusion duration will be 
approximately 4.6 hours.

If an infusion reaction develops, the infusion should be temporarily slowed or interrupted. Upon 
restart, the infusion rate should be half of the infusion rate at the time the infusion was paused. If 
however, the infusion rate was 12 mL/hour before the pause, the infusion should be restarted at 12 
mL/hour.  
Thereafter, the infusion rate may be increased according to the judgment of the investigator, in the

5.4.3. Management of Severe (Grade ≥3) Infusion Reactions to Ofatumumab 
Infusion reactions tend to decrease with subsequent doses of ofatumumab. Most of the infusion / 
injection site reactions reported with ofatumumab have been mild or moderate; however, infusion 
reactions may be severe or even lead to death.  If the investigator judges a grade ≥3 AE to be related 
to the infusion, the infusion must be interrupted and the appropriate clinical intervention begun. 
When the AE decreases to grade <3, the investigator may restart the infusion.  Upon restarting the 
infusion, the infusion rate must be 12mL/hr for the first infusion or 25mL/hr for subsequent 
infusions, and may subsequently be increased according to the judgment of the investigator, as 
described in Table 3 and Table 4 (i.e. not more than doubled and no earlier than every 30 minutes).  
If the severity of the AE does not resolve to grade <3 despite adequate clinical intervention, or the 
same AE increases to grade 3 on three occasions during one infusion, the subject should be 
withdrawn from treatment.

5.4.4 Record of administration 
Accurate records will be kept in the source documents of all drug administration (including 
dispensing and dosing). Time and rate changes of Ofatumumab infusions will be recorded only 
during management of infusion related reaction.   
5.5 Dose Continuation, Modification and Interruption    
Subjects will be evaluated for AEs at each visit with the NCI CTCAE v4.03 (see Appendix 4: NCI 
CTCAE v4.03) used as a guide for the grading of severity.  Sections below describe dose reduction 
steps, instructions for initiation of a new cycle of therapy and dose modifications during a cycle of 
therapy.    
5.5.1 Dose Modification Steps for GSK2110183 
GSK2110183 dose reductions should be taken one dose level at a time per the table below.   
 
Dose levels for GSK2110183: 
 
Dose level 
Daily dose (mg)  
Dose level 0 (starting dose) 
125 
Dose level -1 
100 
Dose level -2 
75 
Dose level -3 
50 
Dose level -4 
25 
 
5.5.2 Instructions for initiation of a New Cycle  
A new course of treatment may begin on the scheduled Day 1 of a new cycle if: 
 The ANC is ≥ 0.5 x 109/L;  
 The platelet count is ≥ 30 x 109/L ;  
 Any drug-related rash, diarrhea, dyspepsia, mucositis or infection that may have occurred has 
resolved to ≤ grade 1 severity (see Section 5.5.3.2); 
 Any drug-related toxicity that may have occurred has resolved to ≤ grade 2 severity 
 
If these conditions are not met on Day 1 of a new cycle, the subject will be evaluated weekly and a 
new cycle of treatment will not be initiated until the toxicity has resolved as described above.  If the 
toxicity does not resolve to  Grade 2 or baseline within 14 days, withdrawal from the trial is 
recommended.  However, if the investigator agrees that further treatment will benefit the subject, 

PMH-GSK2110183-CLL001 
Confidential 
Page 29 of 68  
 
Version 8: 22 May 2014 
 
 
 
treatment can continue with at least one-level dose reduction once the toxicity resolves to  Grade 1 
or baseline. 
 
If GSK2110183 dose reduction was taken during the previous cycle and the cycle was completed 
without requiring further dose modification, then the next cycle will start at the same reduced dose of  
GSK2110183. If ofatumumab or GSK2110183 dosing was omitted for the remainder of the previous 
cycle or if the new cycle is delayed due to toxicity newly encountered on the scheduled Day 1, then 
the new cycle will be started with a one-level dose reduction of GSK2110183, based upon which 
drug was felt by the investigator to be most responsible for the toxicity. 
EXCEPTIONS:   
For toxicities specific to either ofatumumab or GSK2110183, see Section 5.5.3 
For hematopoietic toxicities (neutropenia, thrombocytopenia), only GSK2110183 will undergo dose 
reductions.  Ofatumumab will not be dose-reduced for cytopenias.(see Section 5.5.3.1). 
If GSK2110183 dosing is delayed for ANC < 0.5 x 109/L on Day 1 of a new cycle, the option of 
initiating GCSF support may be taken (see Section 5.5.4). 
 
5.5.3 Instructions for dose modifications or interruption  
5.5.3.1 
Ofatumumab 
Dose delay and dose reduction rules for ofatumumab are as follows and in the table below. 
 There will be no ofatumumab dose reductions.  Infusional reactions will mandate infusion 
rate modifications (Section 5.4.3).   
 For treatment interruptions during a cycle, the 28-day schedule of each cycle will continue to 
be followed.  Missed doses of ofatumumab are not made up.   
 For treatment interruptions that delay the scheduled start of a new cycle, when toxicity has 
resolved as required to allow the start of a new cycle (Section 5.5.2), the restart day of 
therapy becomes Day 1 of the next cycle. 
 There will be no dose reductions of ofatumumab for hematopoietic toxicity (neutropenia, 
thrombocytopenia).  Only GSK2110183 will be dose-reduced for cytopenic toxicity (see 
Section 5.5.4) 
 If GSK2110183 is held for toxicities at the start of a new cycle, ofatumumab will also be held 
until toxicities resolve and allow the new cycle to initiate with both agents.   

PMH-GSK2110183-CLL001 
Confidential 
Page 30 of 68  
 
Version 8: 22 May 2014 
 
 
 
 If GSK2110183 is held for toxicities in the middle of a cycle, ofatumumab may continue 
without interruption, providing the investigator feels that ofatumumab is not contributing to 
the toxicities. 
 
NOTE:  Discontinuation of ofatumumab for infusional adverse events will warrant patient 
removal from study.  If the lowest dose level of GSK2110183 is not tolerated for GSK2110183-
related toxicity, the patient may continue on study with ofatumumab alone. 
 
5.5.3.2 GSK2110183 
Dose delay and dose reduction rules for GSK2110183 are as follows and in the table below. 
 GSK2110183 dose reduction steps are outlined in Section 5.5.1.  
 For treatment interruptions during a cycle, the 28-day schedule of each cycle will continue to 
be followed.  Missed doses of GSK2110183 are not made up.   
 For treatment interruptions that delay the scheduled start of a new cycle, when toxicity has 
resolved as required to allow the start of a new cycle (Section 5.5.2), the restart day of 
therapy becomes Day 1 of the next cycle. 
 If ofatumumab is held at the start of a new cycle, GSK2110183 should also be held.

Grade 1 – 2 
None  
Grade 3 neutropenia with fever 
(temperature ≥ 38.5º C) 
or Grade 4 neutropenia 
Hold (interrupt) both study drugs and follow CBC weekly. 
When neutropenia has resolved to ≤ grade 2, then resume GSK2110183 dose 
at next lower dose level (no dose reduction for ofatumumab). 
 
Instead of waiting for neutrophil recovery, there is an option to use GCSF 
300ug SC OD until neutropenia has resolved to ≤ grade 2, then resume 
GSK2110183 dose at next lower dose level (no dose reduction for 
ofatumumab). 
 
If more than one event of Grade 3-4 neutropenia occurs (i.e. more than one 
dose reduction of GSK2110183 is undertaken), there is an option to use 
GCSF 300ug SC once or twice weekly continuously as secondary 
prophylaxis. 
 
Thrombocytopenia 
Intervention 
Grade 1 – 3 
None  
Grade 4 (<25,000/uL)

None  
Grade 2 - >8.9-13.9 mmol/L 
Monitor blood glucose weekly (either with portable glucometer or with 
chemistry testing).  
 
If Grade 2 hyperglycemia recurs, then decrease GSK2110183 by one dose 
level immediately and carry over into the subsequent cycle.   
 
If Grade 2 hyperglycemia recurs within new cycle, decrease GSK2110183 by 
one dose level immediately and carry over into the subsequent cycle.  
Continue dose reductions (max once per cycle) until no episodes of Grade 2 
hyperglycemia are documented within the new cycle.  
 
If dose level -4 is reached and Grade 2 or higher hyperglycemia recurs, 
discontinue GSK2110183.

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. 

PMH-GSK2110183-CLL001 
Confidential 
Page 33 of 68  
 
Version 8: 22 May 2014 
 
 
 
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. 
 
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 GSK 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. 
 
Hepatitis B Virus (HBV) reactivation 
Hepatitis B Virus (HBV) reactivation can occur in patients receiving CD20-directed cytolytic 
antibodies, including ARZERRA (Ofatumumab), in some cases resulting in fulminant hepatitis, 
hepatic failure and death. 
In patients who develop HBV reactivation while receiving ofatumumab, immediately discontinue 
ofatumumab and start appropriate treatment for HBV, discontinue any concomitant chemotherapy 
the patient is receiving until the HBV infection is controlled or resolved. Due to insufficient data, no 
recommendations can be made regarding the resumption of ofatumumab after resolution of HBV in 
patients who develop HBV reactivation.  
The risk of HBV infection and hepatitis can occur in patients who have not been previously exposed 
to HBV. 
5.5.5 Treatment compliance 
At all times, when dispensing protocol therapy, the study coordinator will review the instructions 
with subjects. Subjects will be asked to maintain a diary to record the drug administration. Subjects 
will be asked to bring any unused drug and empty drug containers to the clinic at their next visit.  

PMH-GSK2110183-CLL001 
Confidential 
Page 34 of 68  
 
Version 8: 22 May 2014 
 
 
 
Research personnel will count and record the number of used and unused drug at each visit and 
reconcile with the patient diary.   
5.6 Concomitant therapy   
5.6.1 Recommended concomitant therapy   
Subjects should receive full supportive care, including transfusions of blood and blood products, 
antibiotics, hematopoietic growth factors, and antiemetics when appropriate.  All patients will take 
allopurinol 300mg PO daily beginning at least 3 days before the start of GSK2110183 Lead-in Phase 
and continuing through 14 days of Cycle 1 on the Treatment Phase (minimum 27 days) for tumor 
lysis syndrome (TLS) prophylaxis.  Subjects should be instructed to maintain adequate hydration and 
maintain urinary output as an additional measure to prevent TLS.  Based on a patient’s reaction and 
laboratory parameters, TLS prophylaxis may be continued or restarted as needed at the Investigator’s 
discretion. 
5.6.2 Prohibited concomitant therapy 
Concomitant use of other anti-cancer therapies, including radiation, or other investigational agents is 
not permitted while subjects are receiving protocol therapy.  In addition, GSK2110183 inhibits 
multiple cytochrome P450 (CYP) enzymes in vitro with CYP3A4 and CYP2C8 showing the lowest 
IC50’s. GSK2110183 shows metabolism dependent inhibition of CYP3A4 and induced CYP3A4 in 
cultured human hepatocytes and GSK2110183 inhibits the human uptake transporter OATP1B1, as 
well as the human efflux transporter BCRP. As a result, other medications that may interact with 
GSK2110183 are prohibited or should be used with caution are outlined in Appendix 2. 
 
5.6.3. Meals and Dietary Restrictions 
 
On all blood sampling days, subjects will fast for at least eight hours prior to the blood draw for 
fasting glucose testing and other blood tests as required by Schedule of study events. Fasting will 
consist of avoiding the oral ingestion of calorie – containing products; however, ingestion of water 
and other non-caloric beverages is permitted. 
Patients should fast 1 hr. before and 2 hrs. after each GSK2110183 dose.  In addition, subjects shall 
abstain from ingestion of any food or drink containing grapefruit and grapefruit juice, Seville

oranges, or pommelos within 7 days prior to the first dose of GSK2110183 until the end of the 
study.   
5.7 Discontinuation of Study Treatment  
Treatment will continue until to a maximum of 18 cycles (months) or the occurrence of any of the 
following events.   
 Disease progression (see Appendix 5 for IWCLL Response Criteria). If a study patient meets 
progressive disease criteria, study meds may be continued at investigator’s discretion and 
after approval from the Study Medical Monitor, if it benefits the study patient. 
 Adverse event(s) that, in the judgment of the Investigator, may cause severe or permanent 
harm or which rule out continuation of the treatment regimen (see Section 6.1) 
 Major violation of the study protocol. 
 Withdrawal of consent 
 Lost to follow up 
 Death 
 
5.7.1 Stopping Safety Criteria 
5.7.1.1   Liver Chemistry Stopping Criteria 
Liver chemistry threshold stopping criteria have been designed to assure subject safety and to 
evaluate liver event etiology during administration of investigational product and the follow-up 
period.  The sponsor-investigator is to review all events which meet liver chemistry stopping criteria 
to determine if the event was due to; 
 tumor lysis, disease related liver involvement 
 concomitant chemotherapy  
 other identified cause and to exclude drug induced liver injury (DILI) due to Ofatumumab 
The criteria are relevant for all Ofatumumab studies because transient elevations in LFTs may be due 
to tumor lysis which is of clinical benefit, disease related liver involvement or due to other 
chemotherapy 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 

PMH-GSK2110183-CLL001 
Confidential 
Page 36 of 68  
 
Version 8: 22 May 2014 
 
 
 
Ofatumumab, rechallenge may be attempted if deemed appropriate by the sponsor-investigator and in 
addition to consent of the subject.  
 
Investigational product will be stopped if any of the following liver chemistry stopping criteria is 
met:   
1. 
ALT 8xULN 
2. 
ALT 5xULN for more than 2 weeks 
3. 
ALT 3xULN and  bilirubin 2xULN (>35% direct bilirubin, bilirubin fractionation 
required‡)  
‡ 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. 
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. 
Note:  The 2 week time point for stopping medication was chosen because it will distinguish from 
LFT elevations due to tumor lysis which should have resolved within this time period.  Medication is 
interrupted and it is a clinical and patient decision if Ofatumumab may be re-started.  The risk: 
benefit ratio is different in an oncology setting and an efficacious therapy may be life-saving.   
 
Report SAE to GSK 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 chemistries normalize or return to within baseline values 
5.7.1.2 
QTc Withdrawal Criteria 
A subject that meets the criteria below will be withdrawn from the study. 
 
QTcB or QTcF > 500 msec or uncorrected QT >600msec (machine or manual overread) 
 
If subject has bundle branch block then criteria is QTcB or QTcF > 530 msec 
These criteria are based on an average QTc value of triplicate ECGs.  If an ECG demonstrates a 
prolonged QT interval, obtain 2 more ECGs over a brief period, and then use the averaged QTc 
values of the 3 ECGs to determine whether the subject should be discontinued from the study. 
5.8 
Follow-Up   
At treatment discontinuation, subjects will undergo a safety assessment approximately 28 days (+/- 4 
days) post the last dose of protocol therapy. Thereafter, follow-up will be required every three 
months until next therapy, relapse or death, whichever comes first (see off study evaluations per the 
Schedule of Assessments, Section 2).  
6 Adverse events 
6.1  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 medical and scientific 
judgment of the investigator 

PMH-GSK2110183-CLL001 
Confidential 
Page 40 of 68  
 
Version 8: 22 May 2014 
 
 
 
 
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 
6.2 Serious Adverse Event (SAE) Definition  
A serious adverse event is one that at any dose (including overdose): 
  Results in death 
 Is life-threatening1 

PMH-GSK2110183-CLL001 
Confidential 
Page 41 of 68  
 
Version 8: 22 May 2014 
 
 
 
 Requires inpatient hospitalization or prolongation of existing hospitalization 
 Results in persistent or significant disability or incapacity2 
 Is a congenital anomaly or birth defect 
 Is an important medical event3 
 
 1“Life-threatening” means that the subject was at immediate risk of death at the time of the serious 
adverse event; it does not refer to a serious adverse event that hypothetically might have caused death 
if it were more severe. 
2“Persistent or significant disability or incapacity” means that there is a substantial disruption of a 
person’s ability to carry out normal life functions. 
3Medical and scientific judgment should be exercised in deciding whether expedited reporting is 
appropriate in situations where none of the outcomes listed above occurred.  Important medical events 
that may not be immediately life-threatening or result in death or hospitalization but may jeopardize 
the patient or may require intervention to prevent one of the other outcomes listed in the definition 
above should also usually be considered serious.  Examples of such events include allergic 
bronchospasm requiring intensive treatment in an emergency room or at home, blood dyscrasias or 
convulsions that do not result in inpatient hospitalization, or the development of drug dependency or 
drug abuse.  A new diagnosis of cancer during the course of a treatment should be considered as 
medically important. 
 
NOTE:  Pregnancies must be reported to GSK; however are not to be reported as SAEs unless they 
meet serious criteria. 
 
6.3 Adverse Drug Reaction Reporting 
Toxicity will be scored using CTCAE Version 4.03 for toxicity and adverse event reporting 
(Appendix 4).  A copy of the CTCAE Version 4.03 can be downloaded from the CTEP homepage 
(HTTP://CTEP.INFO.NIH.GOV).  All appropriate treatment areas should have access to a copy of the 
CTCAE Version 4.03.  All adverse clinical experiences, whether observed by the investigator or 
reported by the patient, must be recorded, with details about the duration and intensity of each 
episode, the action taken with respect to the test drug, and the patient’s outcome.  The investigator 
must evaluate each adverse experience for its relationship to the test drug and for its seriousness. 
6.3.1 Laboratory and Other Safety Assessment Abnormalities Reported as AEs and SAEs 
 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 medical and scientific 
judgment of the investigator are to be recorded as AEs or SAEs. 

PMH-GSK2110183-CLL001 
Confidential 
Page 42 of 68  
 
Version 8: 22 May 2014 
 
 
 
 
 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. 
The investigator must appraise all abnormal laboratory results for their clinical significance.  If any 
abnormal laboratory result is considered clinically significant, the investigator must provide details 
about the action taken with respect to the test drug and about the patient’s outcome. 
6.3.2 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. 
 
6.4 Investigator Reporting Responsibilities 
 
The conduct of the study will comply with all Health Canada safety reporting requirements.   
 
CTA Annual Reports 
Annual Clinical Trial Application reports, under the old Health Canada regulatory framework, have 
been replaced by the annual updated Investigator's Brochure.  Updated Investigator's 
Brochures, including all safety information and global status should be submitted annually. 
Additional information and any changes that have been incorporated in the updated Investigator's 

PMH-GSK2110183-CLL001 
Confidential 
Page 43 of 68  
 
Version 8: 22 May 2014 
 
 
 
Brochure should be highlighted for ease of review and evaluation. If an Investigator's Brochure is 
updated more frequently, it should be submitted as required.  
 
All adverse experience reports must include the patient study number, age, sex, weight, severity of 
reaction (mild, moderate, severe), relationship to drug (probably related, doubtful relationship, 
definitely not related), date and time of administration of test medications and all concomitant 
medications and medical treatment provided.   The investigator is responsible for evaluating all 
adverse events to determine whether criteria for “serious” and as defined above are present.  The 
investigator is responsible for reporting adverse events to GSK as described below. 
6.4.1 Expedited reporting by investigator to GlaxoSmithKline Inc. 
Serious adverse events (SAE) are defined above.  The investigator must inform GSK in writing of 
any SAE within 24 hours of being aware of the event.  The date of awareness should be noted on the 
report.  The written report must be completed and supplied to GSK by facsimile within 24 hours/1 
business day at the latest on the following working day.   
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 GSK concomitant medication, will be reported promptly to GSK. 
 
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 GSK. 
 
The initial report must 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) must be documented on a follow-

PMH-GSK2110183-CLL001 
Confidential 
Page 44 of 68  
 
Version 8: 22 May 2014 
 
 
 
up report.  A final report to document resolution of the SAE is required.  GSK numbers for SAE 
reporting: Tel: 905-819-3057 Fax: 1-866-903-4718;  
email: (Patricia Lavorata) patricia.x.lavorata@gsk.com. 
 
In addition, the investigator or designated person will provide a brief safety update by email or 
telephone every 2 weeks to GSK for the duration during which study drug(s) are administered. 
 
Pregnancy 
Any pregnancy that occurs during study participation must be reported to GSK.   To ensure subject 
safety, each pregnancy must be reported to GSK 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 GSK. 
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 GSK as described above. 
6.4.2 Report of Adverse Events to the Institutional Review Board 
The Principal Investigator is required to notify his/her Institutional Review Board (IRB) of a serious 
adverse event according to institutional policy.   
6.4.3 Investigator Reporting to Health Canada 
For drugs used in clinical trials in Canada, only adverse drug reactions (ADRs) that are both serious 
and unexpected are subject to expedited reporting to Health Canada. Expedited reporting of 
reactions, which are serious but expected, is not required. Expedited reporting is not required for 
serious events from clinical investigations that are considered unrelated to the study product, whether 
or not the event is expected. 

PMH-GSK2110183-CLL001 
Confidential 
Page 45 of 68  
 
Version 8: 22 May 2014 
 
 
 
During a clinical trial the sponsor is required to inform Health Canada of any serious, unexpected 
adverse drug reaction that has occurred inside or outside Canada. ADR report must be filed in the 
cases:  
 
where the ADR is neither fatal nor life-threatening, within 15 days after becoming aware of 
the information  
 
where it is fatal or life-threatening, immediately where possible and, in any event, within 7 
days after becoming aware of the information  
 
within 8 days after having informed Health Canada of the ADR, submit as complete as 
possible, a report which includes an assessment of the importance and implication of any 
findings  
Each ADR which is subject to expedited reporting should be reported individually in accordance 
with the Health Canada / ICH Guidance Document E2A: Clinical Safety Data Management: 
Definitions and Standards for Expedited Reporting. 
Ongoing safety information respecting a drug should be conveyed to Investigator(s) and their 
Research Ethics Board(s). For further information refer to the Health Canada / ICH Guidance 
Documents E6: Guideline for Good Clinical Practice and E2A: Clinical Safety Data Management: 
Definitions and Standards for Expedited Reporting. 
How to file an ADR report to Health Canada: 
A completed ADR Expedited Reporting Summary Form should be attached to the front of the 
completed ADR report (suggested ADR report format: Suspect Adverse Reaction Report - CIOMS 
form of the Council for International Organizations of Medical Sciences (CIOMS)). 
The report should be submitted by fax to the appropriate Directorate. 
6.5 Adverse event updates/IND safety reports 
GSK shall notify the Investigator via an IND Safety Report of the following information: 
 Any AE associated with the use of drug in this study or in other studies that is both serious 
and unexpected. 
 Any finding from tests in laboratory animals that suggests a significant risk for human 
subjects including reports of mutagenicity, teratogenicity, or carcinogenicity. 
 

PMH-GSK2110183-CLL001 
Confidential 
Page 46 of 68  
 
Version 8: 22 May 2014 
 
 
 
The Investigator shall notify his/her IRB/EC promptly of these new serious and unexpected AE(s) or 
significant risks to subjects. 
7 Response Assessment 
Baseline lesion assessments must occur within  28 days of protocol therapy initiation or as indicated 
in Section 2, Schedule of Study Assessments.  All patients will undergo baseline imaging with CT 
scans of neck, chest, abdomen and pelvis. 
Efficacy assessments are scheduled to occur every 4 weeks (beginning of each cycle).  Response and 
progression will be evaluated in this study using the 2008 IWCLL criteria for response in CLL 
(Appendix 5). Radiological methodologies, techniques and/or physical examination, established at 
baseline, for the assessment and measurement of each identified lesion must be used for all 
subsequent assessments.  Repeat CT scanning will be required in patients with baseline CT 
abnormalities in order to confirm CR only and at study discontinuation.   
8 Protocol Amendments/Deviations 
8.1 Protocol amendments 
Any amendment to this protocol must be agreed to by the Principal Investigator and reviewed by 
GSK. Written verification of IRB/EC approval will be obtained before any amendment is 
implemented.   
8.2 Protocol deviations 
When an emergency occurs that requires a deviation from the protocol for a subject, a deviation will 
be made only for that subject.  A decision will be made as soon as possible to determine whether or 
not the subject (for whom the deviation from protocol was effected) is to continue in the study.  The 
subject’s medical records will completely describe the deviation from the protocol and state the 
reasons for such deviation.  In addition, the Investigator will notify the IRB/EC/Health Canada in 
writing of such deviation from protocol. 
Non-emergency minor deviations from the protocol will be permitted with approval of the Principal 
Investigator.

9 Data Management 
9.1 Analyses and Reporting 
Data will be analyzed and reported after accrual has been completed. All subsequent data collected 
will be analyzed and reported in a follow-up clinical report.  
9.2 Data Monitoring Committee 
The Data Safety Monitoring Board (DSMB) at Princess Margaret Cancer Centre will be composed of 
medical and statistical independent reviewers and will meet to review the efficacy and safety data 
and determine a risk/benefit analysis in this subject population.  The purpose of the DSMB is to 
advise on serious safety considerations, lack of efficacy and any other considerations within the 
charge to the Committee.  The DSMB may request additional meetings or safety reports as deemed 
necessary upon discussion with GSK and its representatives.  The DSMB may stop the study 
following review of results from any report.     
9.3 
Study auditing 
9.3.1 Investigator responsibilities 
Investigator responsibilities are set out in the ICH guideline for Good Clinical Practice (GCP) and in 
accordance with the rules and regulations of Health Canada’s Therapeutic Products Directorate. 
Investigators or a designated member of the Investigator’s staff must enter study data onto CRFs or 
other data collection system.  The Investigator will permit study-related audits by IRB/EC review, 
and regulatory inspection(s) (e.g., Health Canada, FDA, EMEA, TPP), providing direct access to the 
facilities where the study took place, to source documents, to CRFs, or other data collection system 
to all other study related documents. 
The Investigator, or a designated member of the Investigator’s staff, must be available at some time 
during audits to review data and resolve any queries and to allow direct access to the subject’s 
records (e.g., medical records, office charts, hospital charts, and study related charts) for source data 
verification.

10   Biostatistical Analysis 
10.1 
Overview 
This is a phase II study to investigate the efficacy of ofatumumab in combination with oral 
GSK2110183 in patients with relapsed or refractory CLL.  The protocol will accrue 31 response 
evaluable patients. 
10.2 
Endpoints 
The primary and secondary objectives will be evaluated by analysis of efficacy endpoints (response 
rates, response duration), progression-free and overall survival, and toxicity.   
 
Evaluable for toxicity - All patients will be evaluable for toxicity from the time of their first dose of 
GSK2110183. After 6 subjects have completed cycle 1 of the Treatment Phase (on combination 
ofatumumab and GSK2110183), an analysis to assess safety and tolerability will be conducted.  
Evaluable for response - All patients who have received at least 1 dose of GSK2110183 during the 
initial Lead-in Phase will be considered evaluable for response.  Duration of Response (DOR) is 
defined, for the subset of patients with a CR or PR, as the time from first documented evidence of 
CR or PR until first documented disease progression or death due to any cause.  If sample size 
permits, duration of response will be summarized descriptively using Kaplan-Meier medians and 
quartiles.  Only the subset of patients who show a CR or PR will be included. 
 
Evaluable for survival - All patients will be evaluable for survival. Overall survival is defined as the 
length of time between the date of first dose of study treatment (GSK2110183) and death due to any 
cause. Progression Free Survival (PFS) is defined as the length of time between the date of first dose 
of study treatment (GSK2110183) and the earliest date of disease progression or death due to any 
cause.  If the patient does not have a documented date of progression or death, then PFS will be 
censored at the date of last adequate assessment.  For a patient who is alive at the time of the 
statistical analysis, the patient will be considered censored at the last date of known contact. 
 
10.3 
Statistical Methodology 
10.3.1   Study Design 

PMH-GSK2110183-CLL001 
Confidential 
Page 49 of 68  
 
Version 8: 22 May 2014 
 
 
 
This is a single-stage phase 2 study evaluating the efficacy of combination ofatumumab and GSK 
2110183.  The protocol will accrue 31 response-evaluable patients.  Patients who have received at 
least one dose of GSK2110183 will be evaluable for safety and response.   
 
10.3.2 Sample Size, Significance Level and Power  
In the pivotal trial of single-agent ofatumumab in fludarabine-refractory CLL which led to FDA 
approval (Wierda et al, 2010), the overall response rate in the BF-ref cohort which is used as the 
historical comparator for our current study population, was 47% (0.470). The proposed study will 
accrue 31 subjects in the sample size to decide whether the proportion responding, P, is less than or 
equal to 0.470 or greater than or equal to 0.670, a 20% increase in response rate. A 20% increase in 
response rate is generally considered a clinically significant change. If the number of responses is 19 
or more, the hypothesis that P≤0.470 is rejected with a target error rate (α error) of 0.10 and an actual 
error rate of 0.079.  If the number of responses is 18 or less, the hypothesis that P≥0.670 is rejected 
with a target error rate of 0.20 and an actual error rate of 0.192. Therefore, the significance level (i.e., 
the probability of rejecting Ho when it is true) is 0.10.  
  
10.3.3   Statistical Analysis 
Univariate analysis of response predictors will be performed using Fisher’s exact test and Wilcoxon 
rank-sum test. Response predictors to be evaluated will include age, abnormal baseline serum 
laboratory values (e.g. LDH, beta-2 microglobulin, albumin, direct antiglobulin test, hemoglobin, 
lymphocytes, neutrophils, platelets, creatinine, ZAP70, CD38), clinical features (bulky adenopathy, 
organomegaly, RAI stage), disease status (relapsed or refractory), number of prior lines of therapy 
(1,2, vs 3 or more), FISH cytogenetics (17p/11q deletion vs none), IgVH status (mutated versus 
unmutated).  Survival will be calculated using the Kaplan-Meier method. Statistical analyses will be 
applied using SAS 9.2. 
10.4 
Safety evaluation 
Data from all subjects who receive any protocol therapy will be included in the safety analyses. 
Subjects who entered the study and did not receive any protocol therapy and had this confirmed, will 
not be evaluated for safety.  Severity of adverse events will be graded by NCI Common Terminology 
criteria version 4.03.  SAEs will be reported at a minimum of up to 6 months after the last dose or to 
the end of the follow-up period whichever is longer. If a subject starts other therapy, then SAEs will 

PMH-GSK2110183-CLL001 
Confidential 
Page 50 of 68  
 
Version 8: 22 May 2014 
 
 
 
no longer be required to be reported.  Note: Causality must be assessed for each study drug 
separately.  SAE forms used must allow for attribution for each study drug to be documented 
separately.  A formal review of safety data after the first 6 patients have completed cycle 1 of the 
Treatment Phase will be performed before continuing accrual.  
10.5  Patient Accrual and Study Duration 
Accrual for this study is expected to be about 2 patients per month. Thus, patient accrual is expected 
to be complete within 18-24 months. Additional time will be required to allow the response data to 
mature. 
  
All patients registered in the study will be accounted for. The number of patients who die or 
withdraw before treatment begins will be specified. The distribution of follow-up times will be 
described and the number of patients lost to follow-up will be given.

The Investigator must obtain informed consent of a subject or his/her designee prior to any study 
related procedures as per GCPs as set forth in the TCPS and ICH guidelines. 
Documentation that informed consent occurred prior to the subject’s entry into the study and the 
informed consent process should be recorded in the subject’s source documents.  The original 
consent form signed and dated by the subject and by the person consenting the subject prior to the 
subject’s entry into the study, must be maintained in the Investigator’s study files. 
11.3 
Study records requirements 
The Investigator must ensure that the records and documents pertaining to the conduct of the study 
and the distribution of the protocol therapy, that is copies of CRFs or other data collection system 
and source documents (original documents, data, and records [e.g., hospital records; clinical and 
office charts; laboratory notes; memoranda; subject’s diaries or evaluation checklists; SAE reports, 
pharmacy dispensing records; recorded data from automated instruments; copies or transcriptions 
certified after verification as being accurate copies; microfiches; photographic negatives, microfilm, 
or magnetic media; x-rays; subject files; and records kept at the pharmacy, at the laboratories, and at 
medico-technical departments involved in the clinical study; documents regarding subject treatment 
and drug accountability; original signed informed consents, etc.]) be retained by the Investigator for 
as long as needed to comply with national and international regulations (generally 2 years after 
discontinuing clinical development or after the last marketing approval).  In Canada records relating 
to clinical trials must be maintained for 30 years. These records must be made available to Health 
Canada within 2 days if there is a risk to the health of trial subjects, otherwise they must be made 
available within 7 days of a request from Health Canada. 
The Investigator agrees to adhere to the document/records retention procedures by signing the 
protocol.

Appendix 1: IWCLL Diagnostic Criteria for CLL 2008 
(Hallek et al. Blood 2008;111:5446)  
 
The diagnosis of B-CLL must have been made at some point in the past, prior to study entry. All of 
the following criteria must have been satisfied at the time of diagnosis: 
 
 Persistent B lymphocytosis of  5 x109/L for the duration of at least 3 months.  
Morphologically, the lymphocytes must appear mature. 
 Lymphocyte immunophenotyping shows the presence of B-cell markers CD19, CD20, CD23 
with CD5 antigen (and absence of other pan-T cell markers)  
 The B cell is monoclonal with regards to kappa or lambda light chain restriction 
 
Greater than 55% prolymphocytes and/or 15 x109/L absolute prolymphocytes in the peripheral blood 
establishes a diagnosis of prolymphocytic leukemia and would be deemed ineligible for this study. 
 
A bone marrow aspirate/biopsy is not necessary for the diagnosis of B-CLL but if done for diagnostic   
purposes.

completion of therapy: 
a) Peripheral blood lymphocytes < 4 x 109/L  
b) Absence of significant lymphadenopathy (>1.5cm) by physical exam and 
appropriate radiology  
c) No hepatomegaly or splenomegaly by physical exam and appropriate  
radiology 
d) Absence of constitutional symptoms 
e) Normal CBC as exhibited by:

erythropoeitin) 
f) Bone marrow to be done at least 2 months after the last treatment and if 
clinical and laboratory results (first 5 points under “Complete Remission”) 
demonstrate that a CR has been achieved.  The marrow sample must be at 
least normoceullar for age, with <30% of nucleated cells being lymphocytes.  
Lymphoid nodules should be absent.  If marrow is hypocellular, a repeat 
sample should be taken after 4 weeks or when peripheral blood counts have 
recovered. 
 
Complete Remission with incomplete bone marrow recovery (CRi) 
This category describes patients who fulfill all the criteria for CR (including the marrow 
examinations) but who have persistent anemia or thrombocytopenia or neutropenia 
apparently unrelated to disease activity but related to drug toxicity.

Appendix 6 – Correlative and Pharmacokinetic Studies 
  
 
Rationale of Correlative Studies  
As a companion study to the proposed clinical trial, we will conduct experiments aimed 
at identifying predictors of response and pharmacodynamic studies to demonstrate target 
inhibition  
 
Clinical Trial Specimens and Processing 
Peripheral blood (PB) and bone marrow aspirate (BMA) samples are collected from 
subjects at screening and day 10 approximately 4 hours after dosing. Where feasible, 
samples are collected at approximately the same time of day for each patient. 
Approximately 10 mls of PB and BMA will be drawn from subjects into heparinized and 
EDTA tubes and sent directly to the lab at Princess Margaret Cancer Centre. One ml of 
PB and BMA will be set aside for flow based pharmacodynamic studies described below. 
The remaining sample will be processed and stored as follows: plasma will be prepared 
and banked; whole blood will be stained for CD38, ZAP-70 and CD20 (to assess for 
expression of the target of Ofatumumab) and analyzed by flow cytometry as described 
below; mononuclear cells (MNC)s from the remaining samples will be prepared by 
Ficoll-Hypaque gradient and the percentage of CLL cells will be determined by CD19 
labeling and flow cytometry. Samples with <85% purity undergo enrichment by 
immunoselection with anti-CD19-conjugated immunomagnetic beads. Cytospin slides 
will be prepared and stored. The cells will then be counted and aliquoted as follows: 
5x106 cells in Trizol for RNA extraction to be used for microarray analysis, 100 x 106 
cells in 9M Urea solution for potential use in proteomics studies and immediately frozen 
at –800C, the remaining cells are snap frozen or frozen in DMSO as viable cells at –800C. 
 
Pharmacogenomic Studies:   
Gene expression analysis will be obtained to address two aims: (i) expression profiles 
associated with response to the agents as a means of identifying biomarkers of response 
and (ii) understanding the cellular actions of the drug in CLL cells. These studies will be 
performed using Affy U133 Plus 2.0 microarrays from Affymetrix using standard

methods. Arrays failing more than one of five different quality control metrics defined by 
the BioConductor package array QCmetrics (MA plots, spatial distribution of feature 
intensities, boxplot distribution of probe intensities, heatmap representation of the 
distance between arrays, relative log expression and normalized unscaled standard error 
plots) will be excluded from further analysis. Expression intensities on 64 CEL files will 
be summarized and present/absent calls made using the MAS5 algorithm 
(BioConductor). A volcano plot will be used to identified probe sets with a greater than 
2-fold difference in expression at day 10 with a p-value <0.05 using Benjamini and 
Hochberg False Detection Rate multiple test correction. The relative gene expression 
proﬁles among the patients with complete response (CR) or partial response (PR) will be 
compared to those with minimal response (MR), stable disease (SD) or progressive 
disease (PD). 
Flow Cytometry Based Pharmacodynamic Studies: 
Cells from PB and BM samples will be evaluated for target modulation and the effects of 
GSK2110183 on downstream signaling targets of AKT (baseline and 4 hours after dosing 
on day 10). Flow cytometry is a highly developed technique for the diagnosis of 
hematological malignancies, based on the correlated measurements of multiple surface 
immunophenotypic markers plus forward and orthogonal light scattering characteristics 
of cell subpopulations. However, with the recent introduction of techniques that measure 
the activation states of signaling pathways using phosphospecific antibodies, the scope of 
flow cytometry now extends into molecular therapeutic monitoring in the clinic. By using 
flow cytometry applications we will determine whether AKT is activated in CLL cells 
pre-treatment and whether administration of GSK2110183 inhibits its downstream targets 
in primary cells. Correlation with patient response will be determined. The results will be 
analyzed on an exploratory basis. 
 
Flow Cytometry Protocol 
We will use a triple antibody (Ab) combination (anti-CD19, anti-CD5, phospho-specific 
antibody) to analyze signaling in CLL cells.  BM and PB samples will be subjected to red 
cell lysis and quality of the sample will be assessed by flow cytometry by measurements

of forward and side scatter, CD19/CD5 and 7AAD staining. Cells will be resuspended in 
stem span H3000 defined serum free medium and aliquoted to FACS tubes.  To one set 
of tubes, 500 uM LY294002 (inhibitor of PI3K) or solvent control will be added and 
incubated at 370C for 30 min. Phosphorylation of AKT and its downstream targets 
(phopho-S6 and phospho-GSK3) will be evaluated by flow cytometry. By comparing 
with the solvent control we can establish whether there is constitutive activation of AKT 
in CLL samples at baseline vs day 10. To a second set of tubes we will activate AKT by 
BCR stimulation with goat anti-IgM F(ab)2 fragment or PMA for 12 minutes and 
compared to solvent. We will determine whether the ability to activate AKT and its 
downstream targets ex vivo is inhibited in samples on day 10 of treatment compared to 
baseline. As an additional control to demonstrate that the cells are viable and signaling is 
intact we will also assess the effect on SYK phosphorylation a non-AKT dependent target 
of BCR signaling. The cells will be fixed and permeabilized using our recently developed 
protocol that optimizes the preservation of phenotypic features and intracellular 
phosphorylated epitopes.  Briefly, samples are removed from the dry bath, fixed by 
adding methanol-free formaldehyde to give a final concentration of 4% for 10 min. The 
cells will be washed in cold wash buffer and then resuspended in 1 ml of cold freezing 
medium consisting of 10% glycerol, 20% fetal bovine serum in RPMI tissue culture 
medium, and stored at –200C and batched for antibody staining so that paired samples are 
analyzed together. 
 
For intracellular phospho-specific antibody staining (phospho-AKT, phospho-S6, 
phospho-GSK3, phospho-Syk, and phospho-RAS S40), thawed cells will be washed and 
0.5 million cell aliquots will be resuspended and permeablilized in 1 ml of 50% methanol 
in 0.9% NaCl and incubated on ice for 10 min.  Cells will then be washed and the cell 
pellet resuspended and labeled with an antibody mix containing primary conjugated 
phospho-specific antibodies described above together with CD19/CD5 (to identifiy the 
CLL cells) and incubated at room temperature for 15 min. Approximately, 30,000 
ungated events will be collected for each sample on a LSR II flow cytometer.  
All patients will have bone marrow aspirate as well as peripheral blood samples drawn at 
baseline and during therapy for these studies.

DIRECTIONS FOR CORRELATIVE SAMPLING: 
 
Correlative study samples: 
 
Bone marrow: 10mL BM aspirate in a heparin tube ( 2 green-top tubes) 
Peripheral blood: 10mL blood in a heparin tube (2 green-top tubes) 
 
Schedule of correlative sample collections:  
 
Aim to collect samples approximately 4 hours post-dosing of GSK2110183 
 
When feasible, samples will be collected at the same time of day for each patient. 
 
Baseline (Within 28 days prior to first dose of GSK2110183) 
After 7 days of GSK2110183 (Lead-in phase) [Day 8 of the lead-in phase 
(Window period of + 2 days to coincide with clinic days)] – Monday through Thursday 
only  
At study discontinuation – only for those patients who go off study for 
progressive disease 
 
Label each tube with the following information: 
 Patient initials Study code 
 Study name – OFA + GSK183 CLL 
Peripheral blood and bone marrow samples will be sent to:

DIRECTIONS FOR PHARMACOKINETIC SAMPLING: 
Pharmacokinetic analyses will be done on blood samples from the first 10 eligible 
participants  
Schedule of pharmacokinetic sample collections: 
 
Peripheral blood sampling for PK studies will be performed on 2 days: 
 
Day 10 of the Lead-in Phase:  
o Predose (before GSK2110183 dose), 0.5, 1, 2, 3, 4, 6, 8, 10-12, 14-22, 
and 24hr after (10-12hr and 14-22hr samples only where collection 
times are feasible) 
 
Cycle 2 Day 22 of the Treatment Phase (with 8th weekly dose of ofatumumab):  
o Predose ((before GSK2110183 dose), 0.5, 1, 2, 3, 4, 6, 8, 10-12, 14-22, 
and 24hr after (10-12hr and 14-22hr samples only where collection 
times are feasible) 
 
Venous blood samples (4 mls for each sample) will be collected into an EDTA 
(k2 or k3) tube at time points specified above.   
 
Label each PK sampling tube with the following information: 
 Patient initials 
 Study number

PK study sample processing instructions: 
Blood should be collected in K3EDTA, plasma should be stored at -200C  
 
1. Sample Handling: 
-At each time point collect 2 mL of blood into a K3EDTA tube.   
-Immediately after the sample is obtained, gently invert the tube 5 to 8 times to 
thoroughly mix the anticoagulant 
  
2. Samples should remain at room temperature prior to centrifugation and 
should be processed within 30 minutes of collection 
- Centrifuge the sample at 2500 to 3000 rpm for 10 to 15 minutes at +2 to 8C to 
achieve a clear plasma layer over the red cells 
The speed and time may be varied according to the make and model of centrifuge 
used. 
-Immediately transfer plasma to corresponding pre-labeled cryovials and store at -
20C. 
1. Cyrovials will be shipped every two weeks  
2. Back-up cyrovials will be stored at site and shipped if required.
