STUDY DESIGN 
This is a randomized, open-label trial to evaluate whether suppression of Hsp27 
production using OGX-427, a second-generation antisense oligonucleotide (ASO), 
in combination with docetaxel can prolong survival time compared to docetaxel 
alone in participants with locally-advanced or metastatic urothelial carcinoma (UC) 
that are relapsed or refractory after receiving a platinum-containing regimen. A 
SYNOPSIS 
TITLE 
A Randomized Phase 2 Study Comparing Docetaxel Alone to Docetaxel in 
Combination with OGX-427 in Patients with Relapsed or Refractory 
Metastatic Urothelial Carcinoma after Receiving a Platinum-containing 
Regimen 
 
HCRN GU12-160; The Borealis-2 Clinical Trial 
STUDY PHASE  
II 
OBJECTIVES 
Primary Objective: 
 
• To determine whether docetaxel administered in combination with OGX-427 
provides a survival benefit compared to docetaxel alone. 
 
Secondary Objectives: 
 
• To compare the safety and tolerability of OGX-427 in combination 
with docetaxel to that of docetaxel alone. 
 
• To compare overall response rate (ORR) (complete response [CR] + 
partial response [PR]), disease control rate (CR+PR+stable disease), 
duration of response, and progression-free survival (PFS) between the 
treatment arms. 
 
• To evaluate the effect of therapy with docetaxel and OGX-427 on 
serum Hsp27 levels and other serum proteins and explore their relation 
with clinical outcomes. 
 
• To evaluate the association of urothelial carcinoma expression of 
Hsp27 measured by immunohistochemistry (IHC) in archival tissue 
with clinical outcomes. 
 
• To evaluate the effect of therapy on peripheral blood circulating tumor 
cells (CTC) enumeration and expression of Hsp27 and other relevant 
proteins via immunoflourescence and levels of telomerase by 
quantitative polymerase chain reaction (PCR), and explore their 
relation with clinical outcomes.  
 
• Somatic (tumor) and germ-line DNA/ RNA will be isolated to allow 
future approved investigations to determine if somatic mutations in 
Hsp27, ABCB1, ABCG2, TUBB4 and other relevant genes of interest 
are associated with treatment outcome (optional informed consent).

STATISTICAL 
CONSIDERATIONS 
 
Participants will be randomized with 1:1 allocation to receive docetaxel ± OGX-
427 using permuted blocks methods within strata.39  Overall survival is defined in 
Section 10.4. 
 
Based on the docetaxel plus vandetanib vs. docetaxel trial33  in a similar patient 
population, the median OS on the docetaxel control arm is expected to be 6 
months (hazard rate of 0.1155). This study is designed to have adequate power to 
detect a 33% reduction in the OS hazard rate (to 0.0770) on the docetaxel + 
OGX-427 arm corresponding to a hazard ratio (docetaxel + OGX-427/ docetaxel) 
= 0.667. If OS follows an exponential distribution, then this difference 
corresponds approximately to a 50% improvement in median OS (to 9 months on 
the docetaxel + OGX-427 arm). The null hypothesis is no difference in treatment 
effect. The primary analysis is a superiority test of OS, performed at one-sided 
0.10 significance level using a stratified logrank test.40 There will be 90% power 
to detect this OS difference assuming 200 participants are enrolled over 31 
months with 8 months of additional follow-up (39 months/3.25 years total 
duration).  Full information under the alternative hypothesis will occur at 162 
deaths.  
 
The Kaplan-Meier (KM) method will be used to estimate OS distributions by 
treatment arm.41 A stratified Cox proportional hazards (PH) regression model will 
estimate the OS treatment hazard ratio and 80% 2-sided confidence intervals in 
unadjusted and adjusted models.42 Exploratory subgroup analyses will investigate 
heterogeneity of treatment effects according to subgroups defined by the 
stratification factors, estimating hazard ratios within subgroups and testing for 
treatment-by-subgroup interaction in Cox PH regression models.  
 
The study will also be monitored for futility with one interim analysis, planned 
prior to completion of accrual at approximately 50% information (approximately 
81 deaths).  The decision for early rejection of the experimental therapy will be 
guided by a hazard ratio boundary using the spending function methodology of 
Lan and DeMets with O’Brien-Fleming parameter to adjust the boundary for the 
actual interim analysis time. If conducted precisely at 50% information, the cut-
off hazard ratio is 1.052 corresponding to a z-scale value of -0.227. If the hazard 
ratio estimate lies above 1.052, the study may be stopped early. Under the null 
hypothesis, the boundary crossing probability is 0.41. The futility rule with a beta 
spent of 0.020 at the one interim analysis is incorporated in the power calculation 
for efficacy and has negligible impact on sample size.

FOLLOW-UP 
PERIOD 
Duration of study treatment will depend on evidence of disease progression and 
tolerance. Participants will be followed until death.  The primary analysis can 
be completed an estimated 8 months following enrollment of the last 
participant.

1. OBJECTIVES 
1.1 
Study Design 
 
This is a randomized, open-label Phase 2 clinical trial to evaluate whether suppression of Hsp27 
production using OGX-427, a second-generation antisense oligonucleotide (ASO), in 
combination with docetaxel can prolong survival time compared to docetaxel alone in 
participants with metastatic or inoperable, locally-advanced urothelial carcinoma (UC) that 
relapsed after, or is refractory to a platinum-containing regimen. A total of approximately 200 
subjects (100 in each arm) will be stratified (see Section 5.6) and randomized to a 1:1 ratio to 
one of two arms. One interim analysis will occur to determine whether to stop study enrollment 
based on survival futility. The trial will not be stopped early based on efficacy. 
 
1.2 
Primary Objective 
 
•    To determine whether docetaxel administered in combination with OGX-427 provides 
a survival benefit compared to docetaxel alone.  
  
1.3 
Secondary Objectives 
 
• To compare the safety and tolerability of OGX-427 in combination with docetaxel 
to that of docetaxel alone. 
• To compare overall response rate (ORR) (complete response [CR] + partial 
response [PR]), disease control rate (CR+PR+stable disease), duration of response 
(see Section 10.3.7), and progression-free survival (PFS) between the treatment 
arms. 
• To evaluate the effect of therapy with docetaxel and OGX-427 on serum Hsp27 
levels and other serum proteins and explore their relation with clinical outcomes. 
• To evaluate the association of urothelial carcinoma expression of Hsp27 measured 
by immunohistochemistry (IHC) in archival tissue with clinical outcomes. 
• To evaluate the effect of therapy on peripheral blood circulating tumor cells 
(CTC) enumeration and expression of Hsp27 and other relevant proteins via 
immunoflourescence and levels of telomerase by quantitative PCR, and explore 
their relation with clinical outcomes. 
• Somatic (tumor) and germ-line DNA/ RNA will be isolated to allow future 
approved investigations to determine if somatic mutations in Hsp27, ABCB1, 
ABCG2, TUBB4 and other relevant genes of interest are associated with 
treatment outcome (optional informed consent). 
2. BACKGROUND 
2.1 
Hsp27 as a Therapeutic Target for Cancer 
Recent technological developments have opened new avenues to identify and validate target 
genes involved in oncogenesis and disease progression, especially in the area of treatment 
resistance. Several proteins have been identified and fully characterized at the Vancouver 
Prostate Centre that promote tumor progression and development of resistance by inhibiting 
apoptosis. This includes clusterin, a heat shock-like protein, and heat shock protein 27 (Hsp27). 

HCRN GU12-160                                                                                                               Version 7 Date 15OCT2014

Heat shock proteins are a family of highly conserved proteins whose expression is induced by 
cell stressors such as hyperthermia, oxidative stress, cytotoxic chemotherapy, and radiation. Heat 
shock proteins such as Hsp27 potently inhibit amorphous aggregation of target proteins under 
stress conditions, acting on the slow, off-folding protein pathway to play a key role against 
harmful protein accumulation.  
 
Hsp27 has a multiplicity of cellular and molecular functions, including transcription factors, 
signal-transducing receptor kinases, cell-cycle regulators, steroid hormone receptors, and 
delivery of ubiquitin-proteasomal degradation pathway.1,2 Cells recovering from stress contain 
elevated levels of Hsp27 and consequently are in a cytoprotected state against a subsequent 
exposure to a normally lethal stress exposure.3 Although an important modulator of the stress 
response in normal cells, in cancer Hsp27 also stabilizes mutated or inappropriately activated 
oncoproteins that contribute to the initiation, growth, and metastasis of human cancers.4-8 
Cancer cells express high levels of Hsp27, in part a consequence of mutated, misfolded protein 
load and are, therefore, pre-adapted to resist treatment-induced cell death.  
 
Hsp27 interacts with many key apoptosis-associated proteins to regulate a cell’s apoptotic rheostat, 
including the intrinsic and extrinsic pathways. The intrinsic pathway primarily functions through 
intracellular death signals, which trigger outer mitochondrial membrane permeabilization, leading to 
the release of cytochrome-c. Cytochrome-c interacts with Apaf-1 and caspase-9 to form the 
“apoptosome” which activates caspase-3, leading to an activation cascade of downstream caspases, 
the so called “effectors” of cell death. The extrinsic pathway is activated through cell membrane-
associated proteins of the TNF receptor family (such as Fas, Trail-R1, Trail-R2 and others) which 
can trigger caspase-independent apoptosis or directly activate caspase-8, which leads to activation of 
the downstream effector caspases. Hsp27 inhibits apoptotic cell death by a variety of mechanisms 
involving both pathways. Hsp27 can inhibit apoptosis by preventing release of mitochondrial 
cytochrome-c,9 by directly interacting with caspase-3,10 inhibiting Fas-induced caspase-
independent apoptosis,10,11 counter-acting reactive oxygen species12 and by stabilizing and 
accelerating recovery of actin filaments, thus preventing disruption of the cytoskeleton.13 Hsp27 
is also involved in regulation of AKT14 and enhances NF-kB activity by increasing degradation 
of I-B.15 Hsp27 also chaperones and shuttles stat3 into the nucleus, enhancing transcription of 
several stat3-regulated survival genes.16  
 
This brief review illustrates that Hsp27 may serve as a therapeutic ‘hyper-node,’ a target situated 
as a ‘hub” at the center of many pathways regulating response of a cell to therapeutic stress. 
Targeting Hsp27 is attractive as it would affect multiple pathways implicated in cancer progression 
and resistance, as opposed to targeting a single pathway, a strategy that might have limited benefits in 
the face of the redundant signaling pathways and heterogeneity characteristic of cancer.  
 
2.2 
The Role of Hsp27 in Bladder Cancer 
Many tumors have been shown to express Hsp27 including bladder, prostate, breast, ovarian, lung, 
endometrial, gastric and hepatic cancers, as well as leukemia and osteosarcoma.17 The role of Hsp27 
in bladder cancer is summarized below. 
 
Hsp27 is expressed in low levels in normal bladder epithelium,18 but expression is increased in 
bladder cancer. Storm et al. were among the first to demonstrate by immunohistochemistry 

HCRN GU12-160                                                                                                               Version 7 Date 15OCT2014

(IHC) that Hsp27 was overexpressed in bladder cancers in > 50% of 23 patients who underwent 
radical cystectomy, with no expression in adjacent normal urothelium.19 Another analysis of 42 
patients with superficial bladder cancer showed that Hsp27 was highly expressed in over 50% of 
cells in 83% of tumors.20 Kassem et al. investigated the expression-profile of stress-related and 
DNA repair genes by cDNA microarray analysis with qRT-PCR confirmation in both a 
radioresistant bladder carcinoma cell line (MGH-U1) and a radiosensitive cell line (S40b) both 
pre and post 2 Gy irradiation.21 Only three genes, including Hsp27, showed consistent down 
regulation in the radiosensitive cell line, suggesting Hsp27 plays a role in radioresistance and 
might be a potential target for cancer therapy.  
 
2.3 
Antisense Oligonucleotide Strategies to Target Relevant Genes 
Targeted therapies that have been approved for use in the clinical setting typically involve the 
use of small molecule inhibitors or antibodies. Unfortunately, many potential therapeutic targets 
are not amenable to such tactics, and, therefore, strategies to inhibit these targets at the gene 
expression level are an attractive concept. Antisense oligonucleotide (ASO) therapy is one such 
strategy to specifically target functionally relevant genes. ASOs are chemically modified 
stretches of single-strand DNA complementary to the mRNA regions of a target gene that inhibit 
translation by forming RNA/DNA duplexes, thereby reducing mRNA and protein levels of the 
target gene.22,23 Expression of specific proteins can be reduced by blocking this translation, and 
subsequent cascades of protein-protein signaling control of cellular proliferation, differentiation, 
homeostasis and apoptosis can be altered. The specificity and efficacy of an ASO relies on the 
targeting afforded by Watson-Crick strand hybridization, where only a match between the target 
sequence and the ASO will lead to efficient hybridization and inhibition of translation. The ASO 
technology platform provides powerful tools to specifically target genes of importance in a 
number of human diseases, including cancer.  
 
Various antisense chemistries have been evaluated to date. The most widely studied are 
phosphorothioate ASOs, water soluble agents designed to resist nuclease digestion through 
substitution of the non-bridging phosphoryl oxygen of DNA with sulfur.24 As a class, 
phosphorothioate ASOs have been well tolerated, and, for the most part, toxicity has been 
non-sequence specific and attributable to the phosphorothioate backbone. However, in clinical 
trials with phosphorothioate “first generation” ASOs, continuous or frequent intravenous (IV) 
infusions were required because of their relatively short plasma half-lives and rapid degradation. 
Therefore, considerable effort has been made to improve the stability and potency of ASOs by 
modifications of the phosphodiester-linkages or alterations to the ring structure or the ribosugars.  
 
Advances in nucleic acid chemistry have yielded ASO modifications such as the 
2´-O-(2-methoxyethyl) or 2´-MOE modification to selected ribosugars that make an 
oligonucleotide more resistant to nuclease degradation.25,26 The 2´-MOE modification is 
incorporated at the 2´-position of the ribosugar moiety at selected portions of the 
oligonucleotides. 2´-MOE ASOs form duplexes with RNA with a significantly higher affinity 
relative to unmodified phosphorothioate ASOs, which results in improved antisense potency both 
in cell culture systems and in animals. In addition, 2´-MOE ASOs display significantly improved 
resistance against nuclease-mediated metabolism relative to earlier types of phosphorothioate 
ASOs,25,26 resulting in significantly improved tissue half-life in vivo, which produces a longer

duration of action and allows for a less frequent dosing regimen.25 Finally, 2´-MOE ASOs have 
shown a more attractive safety profile than unmodified phosphorothioate ASOs. 
 
2.4 
OGX-427 as a Therapeutic Product 
OGX-427 is an ASO designed to bind to Hsp27 mRNA, resulting in the inhibition of the 
production of Hsp27 protein. OGX-427 is similar to endogenous DNA but contains 
second-generation ASO chemical modifications intended to optimize its pharmacological 
potency, pharmacokinetics and safety profile. OGX-427 is a 4-12-4 MOE gapmer 
oligonucleotide with phosphorothiolated internucleotide linkages.  
 
In preclinical studies, OGX-427 or an Hsp27 ASO was tested alone or in combination with other 
drugs in various animal tumor models. Studies were conducted with a control group administered 
a mismatched-sequence control ASO to the target mRNA. Reported below are representative 
experiments in bladder cancer. Other representative experiments in other cancer models such as 
prostate, lung, ovarian, pancreas and breast can be found in the Investigator’s Brochure (IB). 
 
2.4.1 In Vitro Preclinical Pharmacology Studies 
Kamada et al. analyzed the functional significance of Hsp27 expression in bladder cancer cell 
growth, cancer progression, and treatment resistance to cytotoxic chemotherapy in vitro and in 
vivo using the human UMUC-3 bladder cell-line.27 In vitro, they found that Hsp27 
overexpression in UMUC-3 cells accelerated cell growth and increased resistance against 
paclitaxel by greater than 90%. Hsp27 knockdown by OGX-427 or Hsp27 siRNA reduced Hsp27 
mRNA levels by up to 80% and Hsp27 protein levels by 95% in a dose- and sequence-specific 
manner. In addition OGX-427 enhanced the induction of apoptosis and chemosensitized cells to 
paclitaxel by greater than two-fold, reducing the IC50 by > 50%.

2.4.3 Summary of Phase 1 and Phase 2 Clinical Studies Evaluating the Safety and Efficacy of 
OGX-427 
 
A Phase 1 study evaluated patients with cancers that have been shown to over-express Hsp27 
(breast, ovarian, prostate, non-small cell lung [NSCL], and bladder). Patients had to have 
metastatic disease and have failed all therapies felt to be curative or no curative therapy existed. 
OGX-427 was administered, initially as loading doses and then weekly, to 64 patients in 7 

HCRN GU12-160                                                                                                               Version 7 Date 15OCT2014

cohorts. The loading dose was the same as the weekly dose. In Cohorts 1 to 5, OGX-427 was 
administered as a single agent to 6 or more patients per dose level in 3-week cycles starting at a 
dose of 200 mg OGX-427 in Cohort 1. Dose escalations of 200 mg each occurred within cohorts 
up to 1000 mg OGX-427 in Cohort 5. OGX-427 plus docetaxel was administered to two 
subsequent cohorts, Cohorts 6 and 7, at 800 and 1000 mg of OGX-427, respectively.  
 
OGX-427 appeared to be tolerated even at the highest dose of 1000 mg, both as a single agent 
and when combined with docetaxel. A maximum tolerated dose (MTD) was not reached at the 
doses tested. The major non-laboratory toxicity were infusion reactions (rigors, pruritus, 
flushing, pyrexia, arthralgia, hypertension, and erythema) which were seen in approximately 
72% of patients and which appeared to be at increased frequency and severity at the highest 
doses (800 mg and 1000 mg). Patients received only acetaminophen or ibuprofen prophylaxis. 
The majority of the infusion reactions (93%) were grade 1 or 2 and mainly occurred during the 
loading doses and Cycle 1. Reactions were treated with antihistamines, H2 blockers, and 
steroids. Some patients required steroid prophylaxis for repeated infusion reactions.  There was 
no evidence of prolongation of cardiac repolarization. Based on pharmacokinetic studies, 
although the half-life remained constant, there was a non-proportional increase in Cmax and 
AUCinf and a decrease in plasma clearance with increasing doses.  
 
Twenty-two patients in this study were treated with OGX-427 plus docetaxel: 6 with 800 mg 
OGX-427 plus docetaxel and 16 with 1000 mg OGX-427 plus docetaxel.

Administration of OGX-427 plus docetaxel did not, in general, appear to have additive toxicity 
to the known docetaxel safety profile except possibly for Grade 3-4 neutropenia. No dose-
limiting toxicities of OGX-427 were observed in either cohort in combination with docetaxel. 
Grade 3-4 non-laboratory and laboratory adverse events for the combination of OGX-427 and 
docetaxel were as expected for docetaxel, as shown below in  

HCRN GU12-160                                                                                                               Version 7 Date 15OCT2014

Laboratory toxicity was determined based on laboratory data.  The majority of laboratory 
toxicity events were Grade 1 or Grade 2. The most common (> 25% of subjects) Grade 3 or 
higher laboratory toxicities among subjects receiving OGX-427 plus docetaxel were neutropenia, 
lymphopenia, and prolonged aPTT, as shown in Table 3 below. Increases in lymphopenia and 
prolonged aPTT are known ASO-class effects but do not appear to have clinical sequelae.  More 
detailed safety information on patients receiving this combination is available in the OGX-427

Reductions in tumor markers were observed in patients with both prostate (PSA) and ovarian

in over half the patients. These results were observed in each of the 7 cohorts and each disease 
category enrolled.

Thirty of the 64 patients had baseline and at least one post-baseline assessment of measurable 
disease. A total of 8 of 30 patients (27%) had a decrease in measurable disease from baseline of 
at least 15%. Two heavily pretreated patients with metastatic bladder cancer and visceral 
metastases were treated with docetaxel and OGX-427 at the 1000 mg dose. One patient survived 
8 months and the other survived 20 months. 
 
A Phase 2, open-label, randomized, cross-over study is currently underway (Study PR-01). This 
study is designed to evaluate the anti-tumor effects of OGX-427 with prednisone compared to 
prednisone alone in men with CRPC who have not previously received chemotherapy for 
metastatic disease. The primary endpoint is the proportion of patients without disease 
progression at 12 weeks after start of study treatment. The study also assesses the proportion of 
patients with a PSA decline and/or stable disease at the 12-week evaluation; measurable disease 
response; progression free survival; time to disease progression; and circulating tumor cells 
counts pre- and post-study drug.  
 
In the PR-01 study, subjects are randomized to a Treatment Arm, which starts with three loading 
doses of 600 mg OGX-427 within 10 days, followed by weekly doses of 1000 mg of OGX-427 
IV along with prednisone, or to a Control Arm with prednisone alone. After documentation of 
disease progression, subjects on the Control Arm have the option to cross over to receive OGX-
427 plus prednisone (designated as the Crossover Arm). 
 
As of the cutoff date of April 26, 2012, safety data are available for 56 randomized subjects (27 
in the Treatment Arm and 29 in the Control Arm). The most frequently reported non-laboratory 
AEs among subjects treated with OGX-427 (Treatment and Crossover Arms) were chills, 
diarrhea, nausea, and fatigue; the majority of AEs were Grade 1 or Grade 2. The most common 
laboratory AEs among subjects treated with OGX-427 were anemia, lymphopenia, and 
hyperglycemia. Because of the high frequency of infusion reactions in the Phase 1 study, 
especially at the higher OGX-427 doses, the loading dose for all subjects in study PR-01 was 
decreased to 600 mg. In addition, subjects in study PR-01 received both an antihistamine and a 
histamine antagonist as prophylaxis. Infusion reactions were seen in 52% of subjects. 
Efficacy data are available on a subset of 42 subjects as of May 15, 2012 (22 in the Treatment 
Arm and 20 in the Control Arm). Twelve of 22 (55%) subjects in the Treatment Arm and 6 of 20 
(30%) in the Control Arm had no documented disease progression at 12 weeks. Thirteen of 22 
(59%) subjects on the Treatment Arm had a > 30% decrease in PSA compared to 6 of 20 (30%) 
on the Control Arm. Nine subjects in the Treatment Arm and 12 in the Control Arm had 
measurable disease at baseline. One subject in the Treatment Arm (11%) had a complete 
response based on measurable disease. Also in the Treatment Arm, 3 subjects (33%) achieved a 
partial response, 1 (11%) had stable disease, and 4 (44%) did not have a post-baseline 
assessment at the time of this analysis. In the Control Arm, 7 subjects (58%) achieved stable 
disease, 2 (17%) had disease progression, and 3 (25%) did not have a post-baseline assessment at 
the time of analysis. 
 
Another Phase 2 study (Study OGX-427-02) is currently underway evaluating gemcitabine and 
cisplatin in combination with OGX-427 or placebo. This randomized, double-blind Phase 2 study 
is being conducted in patients with advanced transitional cell carcinoma who have not previously 
received chemotherapy for metastatic disease and are not candidates for potential curative

surgery or radiotherapy. The primary endpoint is overall survival (OS). The study also assesses 
safety and tolerability of OGX-427 in combination with gemcitabine and cisplatin; objective 
response; levels of Hsp27, clusterin, and CTCs; and pharmacokinetic parameters. 
As of the cut-off date of April 26, 2012, 16 subjects have been randomized and 12 subjects have 
been treated in this study. Four serious adverse events have been reported to date in 4 subjects, 
including pneumonia, pulmonary emboli, renal failure, and pancreatitis. Safety data are currently 
blinded. 
 
A fourth study with OGX-427 is ongoing at a single medical center in Canada (Study BL-01) as 
an Investigator-sponsored study. In this study, OGX-427 is administered by intravesical 
instillation (directly into the bladder) in subjects with bladder cancer prior to transurethral 
resection of the bladder tumor or radical cystectomy. In this Phase 1 study, subjects are treated 
with intravesical OGX-427 on days 1, 3, 5, and 8 and then undergo surgery on days 9-12. The 
dose of OGX-427 is being escalated after tolerability and safety assessment for each cohort 
(20uM, 50uM, 100uM, 250uM, 500uM, and 750uM). Objectives include safety and 
pharmacokinetics, pharmacodynamics, and biologic effects of intravesical OGX-427. Currently, 
13 subjects have been enrolled in the trial, and the 250uM cohort has been completed. No 
significant drug-related adverse events have been reported and no dose limiting toxicity (DLT) 
has been observed. To date, pathological staging of surgical specimens revealed that 5 of the 13 
patients (38%) had complete responses.

clinical trial results for OGX-427.

Metastatic Urothelial Carcinoma 
 
Urothelial carcinoma is the fifth most common malignancy in the United States and accounts for 
13,000 deaths yearly.28 Yet metastatic urothelial cancer has seen few significant advances in the 
last decade. Standard of care in the United States consists of a cisplatin-based upfront therapy 
(gemcitabine plus cisplatin [GC] or methotrexate, cisplatin, doxorubicin, and vinblastine 
[MVAC]). Once patients progress through one of these regimens, there is no second-line 
standard of care. Many agents, including docetaxel, paclitaxel, and ifosfamide, have shown 
single agent responses (between 10-20%, which improve with combination therapy),29-32 yet no 
randomized trial has shown the benefit of one over another. In fact, no second-line trial has 
demonstrated improved survival with any chemotherapy agent. Because of this lack of a gold 
standard, practice patterns differ, although taxane therapies are the most commonly used (either 
in combination or as single agents).  
 
Relevant to this protocol, docetaxel (Taxotere) is a commonly used chemotherapeutic agent in 
urothelial carcinoma, both as a single agent and in combination with other therapies. In a Phase 2 
study of single agent docetaxel in second-line or later metastatic urothelial carcinoma, the 
response rate was 13%, with a median survival of 9 months.29 This response rate and median 
survival is in line with other single agent chemotherapy Phase 2 trials in this patient population. 
The addition of vandetanib to docetaxel in the second, third, or fourth line did not result in 
improved overall survival (OS), progression-free survival (PFS), or overall response rate (ORR) 
among patients with metastatic urothelial cancer pretreated with platinum-based therapy. In this 

HCRN GU12-160                                                                                                               Version 7 Date 15OCT2014

30
randomized, double-blind, Phase 2 trial (n=142), patients receiving docetaxel plus vandetanib 
had a median PFS of 2.56 months, median OS of 5.85 months, and ORR of 7%; patients 
receiving docetaxel plus placebo had a median PFS of 1.58 months, median OS of 7.03 months, 
and ORR of 11%.33 In addition, patients on this trial did not show differences in PFS and OS 
based on prior history of paclitaxel treatment. 
 
New agents or combination treatments that prolong survival in the second-line setting are 
urgently needed. In an effort to identify clinical and laboratory pretreatment factors that predict 
OS among second-line patients, Bellmunt et al. prospectively analyzed patients with metastatic 
transitional cell carcinoma of the urothelial tract who had treatment failure following first-line, 
platinum-based therapies and were enrolled in a Phase 3 clinical trial of vinflunine and best 
supportive care versus best supportive care alone.34 Three adverse risk factors were prognostic 
of OS: Eastern Cooperative Oncology Group (ECOG) performance status > 0, hemoglobin level 
< 10 g/dL, and the presence of liver metastases. A scoring system was developed to classify 
second-line urothelial cancer patients into four risk groups based on the presence of 0, 1, 2, or 3 
of these prognostic risk factors. Application of this scoring system to the 370-patient cohort 
resulted in median OS times for these groups of 14.2, 7.3, 3,8, and 1.7 months (P<0.001), 
respectively.  
 
In addition, time from prior chemotherapy has been shown to be important in determining 
outcomes in previously treated urothelial carcinoma patients.35 Patients with less than 3 months 
since the last date they received prior chemotherapy to the date of initiation of subsequent 
chemotherapy had significantly worse outcomes compared to those that initiated subsequent 
therapy 3 months or later. 
 
2.6 
Rationale 
 
Current treatments for urothelial carcinoma have limited success in preventing tumor recurrence 
and/or progression, and overall mortality rates have remained fairly constant. The prognosis of 
patients with invasive or metastatic disease is extremely poor. Cisplatin-based chemotherapy 
regimens, such as gemcitabine and cisplatin, are the mainstay of treatment for patients with 
advanced disease. However, twenty years of experience have failed to make much progress in 
improving patient outcomes. Although urothelial carcinoma is considered to be a chemotherapy-
sensitive neoplasm, the efficacy of combination chemotherapy has been restricted because of de 
novo drug resistance and acquired resistance. Thus, there is a need to identify mechanisms by 
which cancer cells inhibit the effects of chemotherapy and to develop novel treatments that, 
hopefully, improve survival, especially in relapsed or refractory urothelial carcinoma after 
receiving platinum-based chemotherapy. 
 
Heat shock proteins such as Hsp27 play a crucial role in regulating the balance between cell 
survival and death by acting as molecular chaperones to facilitate transport, folding, and 
assembly of polypeptides. Hsp27 expression is increased in many cancers including bladder 
cancer. Overexpression has been associated with inhibition of apoptosis, increased 
cytoprotection, and the development of treatment resistance by inhibition of apoptotic cell death 
induced by chemotherapeutic agents. ASOs specifically hybridize with complementary mRNA 
regions to form RNA/DNA duplexes to inhibit target gene expression. OGX-427 is a second-

HCRN GU12-160                                                                                                               Version 7 Date 15OCT2014

31
generation ASO that effectively targets and down-regulates Hsp27 mRNA and has been shown 
to increase apoptosis, inhibit tumor growth, and sensitize cells to chemotherapy in a variety of 
malignancies including bladder cancer. These findings provide preclinical proof of principle for 
its use in the treatment of this disease.  
 
A Phase 1 study in patients with prostate, breast, ovarian, lung, and bladder cancer has shown 
tolerable doses of OGX-427 up to 1000 mg when administered alone or with docetaxel 
chemotherapy. Biological activity as monotherapy was observed by measurable disease 
response, decreases in tumor markers, and circulating tumor cell (CTC) responses. Another 
Phase 1 study evaluating OGX-427 by intravesical instillation (directly into the bladder) in 
subjects with bladder cancer prior to transurethral resection of the bladder tumor or radical 
cystectomy has shown 38% complete pathological responses. 
 
Given the poor outcomes for patients with advanced, refractory metastatic urothelial carcinoma, 
the preclinical rationale for the addition of OGX-427 to reduce treatment resistance, and the 
Phase 1 study demonstrating that combination with docetaxel is safe, we propose a trial 
considering docetaxel plus OGX-427 in previously treated urothelial carcinoma with a platinum-
based regimen. Docetaxel is a relevant control arm as there is no standard of care in relapsed, 
refractory metastatic urothelial carcinoma, and docetaxel is a widely-used option in this situation. 
 
Dramatic differences in results between Phase 2 studies testing the same treatment regimen have 
been observed in urothelial cancer. This is largely due to varying ratios of good, intermediate, 
and poor prognosis patients enrolled on those studies.36 Therefore, a randomized and 
appropriately stratified design affording a comparison of an investigational therapy against a 
control is ideal to investigate the activity of docetaxel and OGX-427. Improved OS compared to 
a contemporaneous control (rather than an historical control, which could suffer from many 
biases) would provide a strong rationale to move forward with Phase 3 testing in this patient 
population. The use of objective response as the primary endpoint is not an ideal surrogate for 
clinical benefit. Median OS in patients with metastatic urothelial cancer previously treated with 
chemotherapy is only 6-7 months. The recent contemporary Phase 2 study of taxane 
chemotherapy demonstrated a median OS of 6.7 months.33 Since survival time is so short, using 
OS as a screen for clinical benefit in this context is appropriate. This study will stratify patients 
based on the presence of 3 known adverse prognostic factors: hepatic metastases, anemia, and 
impaired performance status, which have been identified as driving outcomes in previously-
treated patients with advanced bladder cancer.37 In addition, time from prior chemotherapy has 
been shown to be important in predicting outcomes and adds significance to the second-line 
prognostic factors. 
 
Therefore, there will be two stratification factors. Randomization will be stratified based on  
the risk categories: presence of 0 or 1-3 adverse prognostic factors (liver metastases, hemoglobin 
< 10 g/dL, ECOG PS 1) and time from prior systemic chemotherapy < 3 months vs.  3 months 
(as defined in Section 5.6).

Correlative Studies Background 
 
This study will assess the effect of study treatment on serum Hsp27 levels and may evaluate 
other proteins (e.g., other Hsp family members and their client proteins) as biomarkers that may 
emerge as prognostic or predictive factors in urothelial cancer. Archival tumor tissue will be 
collected to assess Hsp27 IHC staining to determine whether tissue levels of Hsp27 are 
associated with outcome in patients treated with OGX-427. It is hypothesized that elevated 
baseline Hsp27 levels will have improved outcomes when treated with OGX-427 both in the 
tumor tissue and serum. In addition, to facilitate future research and better understand the 
mechanism of treatment sensitivity, somatic (tumor) and germ-line DNA/RNA will be isolated 
from archival tumor tissue for use in future approved investigations to determine if somatic 
mutations are associated with treatment outcome.

Microfilter Platform for Circulating Tumor Cell Capture and Analysis 
 
Even in the presence of more effective regimens to treat advanced malignant cancers, there still 
exists a crucial need to predict and monitor therapeutic efficacy in real time. The biologic 
heterogeneity of cancer and the large populations afflicted pose the pivotal questions of whom to 
treat, with which therapies and how to monitor the efficacy of therapy, challenges that can only 
be addressed through the development of more accurate and informative biomarkers. This need 
is evident for other malignancies where useful predictors of treatment response have provided a 
major advance, such as in breast cancer (Herceptest) or colorectal cancer (K-Ras mutations). 
Peripheral blood circulating tumor cells (CTCs) recently have been shown to have prognostic 
and predictive value in metastatic breast, colon and prostate cancer. In prostate (as well as in 
breast and colon) cancer, quantification of CTCs before and after therapy has been shown to 
predict overall disease response, and the CellSearch assay has been approved by FDA to assess 
such response. This assay, nevertheless, has limitations. Aside from associated costs, the assay 
depends on enrichment of CTCs based on their expression of EpCAM, a variably expressed cell 
surface marker, adversely affecting CTC enrichment. It is also likely that enumeration of CTC 
alone may be inadequate as prognostic and predictive marker for therapeutic response; particular 
biomarkers expressed on CTCs may provide a wealth of additional information about clinical 
outcome and response to therapy. Finally, although the utility of CTC analysis in other common 
malignancies has been widely demonstrated, few studies have investigated the utility of CTCs to 
predict therapeutic response in bladder cancer, and there are currently no studies that directly 
evaluate the expression of a therapeutic target on CTCs to predict and monitor treatment 
efficacy.  
 
In response to these unmet clinical needs, collaborators at the University of Miami – Miller 
School of Medicine have developed a microfabricated parylene membrane-based device capable 
of capturing CTCs based on their larger size relative to hematopoietic cells, and have shown its 
utility in capturing CTC in cancer patient blood samples with high efficiency and with enhanced 
ease and speed.43 Briefly, 7.5-10 ml blood samples are drawn from participants by standard 
phlebotomy measures into anticoagulant tubes. Immediately upon receipt, the blood is diluted 
1:1 in 1x PBS, and briefly fixed in 1% formalin at room temperature for 10 minutes. Following 
fixation, the blood samples are passed through the microfilter device at low, steady pressure 

HCRN GU12-160                                                                                                               Version 7 Date 15OCT2014

using syringe pump. Following filtration the microfilter is disengaged from its housing cassette 
and placed onto a glass microscope slide for downstream molecular analyses. There is evidence 
that not only the capture, but also the characterization of CTC can provide additional information 
regarding optimal therapeutic efficacy, as demonstrated by the evaluation of EGFR mutations in 
lung cancer CTCs from patients who are candidates for anti-EGFR therapy.44 We have further 
enhanced our microfilter devices by incorporating the capability for downstream molecular 
characterization, such as on-chip multi-marker immunohistochemistry and genetic tests, which 
adds a useful dimension besides CTC quantification.  
 
Molecular Characterization of CTCs by Immunoflourescence: Recently, the microfilter device 
for CTC capture and molecular analysis was used in the SWOG S0421 phase III double-blind 
clinical trial to evaluate the efficacy of Atrasentan, an endothelin-1 A receptor (ETAR) inhibitor, 
in combination with docetaxel versus docetaxel + prednisone to treat metastatic castration-
resistant prostate cancer (mCRPC). Preliminary analysis of 456 blood samples total from 152 
mCRPC patients taken at three timepoints during treatment enrolled and randomized into the 
treatment arms of the study indicates that the microfilter device successfully captures CTCs to 
predict therapeutic efficacy, and evaluation of ETAR expression directly on CTCs demonstrates 
the potential of captured CTCs to be characterized for expression of therapeutic targets and 
markers of response [unpublished data]. In the current study, we plan to evaluate our ability to 
predict the therapeutic efficacy of OGX-427 in combination with docetaxel versus docetaxel 
alone in metastatic bladder cancer as a second line therapy through CTC enumeration, as well as 
evaluate expression of the OGX-427 drug target, Hsp27, directly on CTCs to predict and monitor 
treatment efficacy.   
 
Molecular Characterization of CTCs by Quantitative Measurement of Telomerase Expression: 
Telomerase is an enzyme which lengthens and protects telomeres, the tandem repetitive DNA 
sequences that cap the ends of human chromosomes. Whereas benign, terminally differentiated 
tissues have extremely low telomerase level, malignant cells from a variety of cancers have 
significantly elevated telomerase expression and telomerase activity levels. The robust presence 
of telomerase in cancer cells and its relative absence from benign tissues has led to a profusion of 
studies to assess its biomarker utility for diagnosis and prognosis. Telomerase has emerged as a 
cancer-specific biomarker that is consistently detected in primary tumors, metastases, and 
circulating tumor cells. In multiple studies over the past decade, telomerase activity was shown 
to provide significant diagnostic and prognostic utility across numerous cancer types.   
 
As described in above, telomerase is a ribonucleoprotein complex that synthesizes 6 base 
telomeric repeats (TTAGGG) onto the 3’ end of existing telomeres. This mechanism of action 
led to the development of the TRAP (Telomeric Repeat Amplification Protocol) assay, a two-
step PCR-based method to detect telomerase activity in vitro. Briefly, a cell or tissue sample is 
lysed in CHAPS-based lysis buffer and the cell lysate, which contains telomerase, is collected 
and analyzed in 2 steps: In the first step, called the extension step, an aliquot of cell lysate is 
mixed with a telomerase substrate oligonucleotide (TS) in the presence of dNTPs. Telomerase 
catalyzes the addition of telomeric repeats onto the 3’ end of TS. The amount of extended 
telomeric repeats is directly proportional to the amount of telomerase present in the cell lysate. In 
the second step, called the amplification step, the products of the extension reaction (step 1) are 
amplified by PCR using a reverse primer and are subsequently visualized and quantified by gel 

HCRN GU12-160                                                                                                               Version 7 Date 15OCT2014

electrophoresis. More recently, variety of real-time quantitative PCR (qPCR) detection methods 
have been developed in order to make the amplification (second) step simpler, faster and more 
reliable. After the extension (first) step is completed (as per classical TRAP assay), a reverse 
“ACX” primer is used in the second step for amplification by real-time PCR. The ACX primer 
contains mismatches which prevent primer-dimer formation while still enabling amplification of 
the extension products. Prior to starting every qPCR-TRAP assay, cell numbers and protein 
levels in cell lysates are measured and equalized to ensure that results reflect equal input 
amounts. Ultimately, qPCR-TRAP produces a SYBR green curve from which the threshold cycle 
of detection (Ct – inversely proportional to starting amounts) is calculated for each sample. 
Standard control samples are run with every qPCR-TRAP reaction to generate a standard curve. 
This curve serves both as a control for the efficiency of the real-time PCR reaction and for 
normalization and comparison of the unknown samples to the known standard controls.  
 
qPCR-TRAP has also been used to detect changes in cancer cell telomerase activity when 
inhibiting proliferation, as well as telomerase activity levels from prostate cancer cells derived 
from freshly resected primary prostatectomy specimens. Most recently, as part of the SWOG 
S0421 phase III double-blind clinical trial described previously above, blood samples were 
evaluated from 262 mCRPC patients being treated with Atrasentan in combination with 
docetaxel versus docetaxel + prednisone, the standard of care for this diagnosis. Results from this 
study demonstrate that telomerase activity measured from CTCs captured by the microfilter 
device constituted the first-ever CTC-derived biomarker prognostic of overall survival in a large 
prospective clinical trial.  In the current study, we plan to use our previously optimized protocols 
to predict the therapeutic efficacy of OGX-427 in combination with docetaxel versus docetaxel 
alone in metastatic bladder cancer as a second line therapy through the measurement of 
telomerase activity in CTCs.

4. REGISTRATION PROCEDURES 
 
All participants must be registered through the Hoosier Cancer Research Network, Inc. (HCRN) 
Electronic Data Capture (EDC) system. 
 
Detailed guidelines for participant registration and electronic case report form (eCRF) 
completion can be found in the Study Procedures Manual (SPM) associated with this protocol.   
Participants must be registered prior to starting protocol therapy and begin therapy within 5 
working days of registration and randomization.   
 
Randomization will occur immediately after registering a participant. See Section 5.6 for 
randomization procedures.  
 
Blinding 
 
The study treatment is not blinded to the participant or the investigator. 
 
5. TREATMENT PLAN  
 
This is a randomized, open-label Phase 2 clinical trial in participants with metastatic or 
inoperable, locally-advanced urothelial bladder cancer who require additional chemotherapy 
after receiving a platinum-based regimen. A total of approximately 200 participants (100 in each 
arm) will be stratified (see Section 5.6) and randomized in a 1:1 ratio to one of two arms: 
 
Arm A [docetaxel + OGX-427] and  
Arm B [docetaxel alone]  
 
All participants will be evaluated for inclusion in the study during the Screening Period. 
Participants who are eligible for the study will be randomized as described in Section 5.6 and 
will start study treatment within 5 working days of registration and randomization. The general 
treatment plans for both arms are described separately below: 
 
Participants in Arm A will receive 3 doses of 600 mg of OGX-427 during a Loading Dose 
Period and then weekly OGX-427 at a dose of 600 mg, as shown in Figure 7A below. 
Participants in Arm A will also receive docetaxel at 75 mg/M2 once every 21-day cycle. 
Following the loading doses, participants will receive docetaxel and OGX-427 on 21-day cycles

during the Treatment Period until disease progression, unacceptable toxicity related to docetaxel, 
voluntary participant withdrawal, or a maximum of 10 docetaxel cycles (see Section 5.14). Arm 
A participants who have completed all 10 cycles of docetaxel, or those who are removed from 
docetaxel due to toxicity, have completed disease assessments after at least 2 cycles, and do not 
have disease progression or unacceptable toxicity related to OGX-427, should continue weekly 
OGX-427 infusions as maintenance treatment until disease progression or unacceptable toxicity 
related to OGX-427.  
 
Participants in Arm B will receive docetaxel at 75 mg/M2 once every 21-day cycle as shown in 
Figure 7B below during the Treatment Period until disease progression, unacceptable toxicity 
related to docetaxel, voluntary participant withdrawal, or a maximum of 10 docetaxel cycles (see 
Section 5.14).

5.1 OGX-427 Loading Dose Period: Arm A Participants Only 
 
Participants randomized onto the investigational arm (Arm A) are to receive OGX-427 beginning 
with a Loading Dose Period prior to the initiation of docetaxel treatment on Day 1 of Cycle 1. 
The first dose of OGX-427 for the Loading Dose Period must be administered within 5 working 
days of registration and randomization. 
 
Three doses of 600 mg OGX-427 will be administered IV during the Loading Dose Period.  Up 
to nine days are allowed for completing the three loading doses to account for clinic visits, 
weekends, and holidays. There must be at least one “non-infusion” day between each 
administration of OGX-427 (i.e., every other day) during the Loading Dose Period and between 
the third loading dose of OGX-427 and Day 1 of Cycle 1 (when docetaxel treatment will begin). 
More than one day can separate administrations, provided that all 3 doses are administered 
within the 9 days. A maximum of 7 days between the 3rd loading dose and Cycle 1, Day 1 is 
allowed. A common schedule would be to give the three loading doses of OGX-427 on 
Monday, Wednesday, and Friday, with Cycle 1 Day 1 starting on the following Monday. 
The day prior to Day 1 of Cycle 1 (identified as Day 0) should be a no treatment day (e.g., 
Sunday in the above example). Participants will receive each dose of OGX-427 as an 
approximately 2-hour infusion. Sites should make every effort to target infusion timing to be as 
close to 120 minutes as possible. However, given the variability of infusion pumps from site to 
site, a window of ± 10 minutes is permitted. 
 
Because Grade 1 and 2 constitutional symptoms (e.g., chills, fever, pruritus, flushing) are seen in 
the majority of participants during the loading-dose infusions, all participants will be 
premedicated with a H2 blocker, antihistamine, and if needed corticosteroid during the loading 
doses and Cycle 1 (Days 1, 8, and 15), at a minimum.  
 
If the participant has not manifested signs or symptoms of an infusion reaction during the 
loading doses and Cycle 1, participant may be treated in subsequent cycles without some or all of 
the premedications.  Should Grade 2 or greater reactions occur, the participant should resume 
premedications, including dexamethasone, prior to Study Drug for the duration of the study. 
See Section 5.13.1. 
 
5.2 21 Day Treatment Cycles (Beginning Day 1 of Cycle 1) 
 
Arm A Participants Only: 
Following completion of the loading dose period, 600 mg OGX-427 will be given IV weekly on 
Days 1, 8, and 15 of each 21-day cycle. OGX-427 must be administered prior to docetaxel on 
Day 1 of each cycle. Docetaxel should be administered immediately following the completion of 
the OGX-427 infusion. Ensure that IV tubing and Y sites are flushed thoroughly with normal 
saline between administration of OGX-427 and docetaxel. 
 
Arm B Participants Only: 
The first dose of docetaxel must be administered within 5 working days of registration and 
randomization.

Both Arm A and Arm B Participants: 
Docetaxel (75 mg/M2) will be administered IV on Day 1 of each 21 day cycle.  
 
Treatment cycles will continue until disease progression by RECIST v1.1, unacceptable toxicity, 
completion of 10 cycles, or voluntary withdrawal (see Section 5.14). 
 
5.3 OGX-427 Maintenance: Arm A Participants Only 
 
Following completion of 10 cycles of docetaxel, 600 mg OGX-427 will continue to be 
administered by IV weekly as maintenance therapy in Arm A participants who do not have 
disease progression (i.e., stable disease or better) (see Section 5.9). Participants without 
documented disease progression who have discontinued from docetaxel treatment not due to 
OGX-427-related toxicity can also continue to receive OGX-427 maintenance as long as they 
have completed disease assessments following at least 2 cycles of chemotherapy.  Maintenance 
with OGX-427 will continue until disease progression or unacceptable toxicity. 
 
5.4 
Follow-up: All Participants 
 
Imaging studies will be performed every 6 weeks (i.e., after completion of Cycles 2, 4, 6, 8 and 
10) until disease progression and with any sign or symptom of new or worsening disease; CT of 
chest/abdomen/pelvis is preferred but MRI is acceptable, especially for participants with 
increased risk of contrast-related nephropathy or other contraindications. For Arm A, scans will 
be performed every 2 cycles (6 weeks) during the 21-day cycles of docetaxel administration and 
every 6 weeks during maintenance OGX-427 administration until disease progression; for Arm 
B, scans will be performed every 6 weeks during the 21-day cycles of docetaxel administration 
until disease progression. A window of ±1 week is allowed for scheduling, provided all scans 
are completed before the subsequent cycle is scheduled to begin. Bone scans will be repeated, 
if positive at baseline, every 6 weeks during the first 4 cycles of treatment (i.e., at the end of 
Cycles 2 and 4) and then every 12 weeks thereafter until disease progression (i.e., at the end of 
Cycle 8, at End of Treatment, and during maintenance with OGX-427 [Arm A only]).  
 
If new clinical signs or symptoms of disease progression have developed, repeat imaging as 
clinically indicated, preferably using the same modality as baseline, when appropriate. 
 
All participants will have an End of Treatment (EOT) visit when they discontinue study 
treatment. All participants will be followed until documented disease progression. Participants 
who discontinue study treatment for any reason, without documented disease progression, and 
who initiate other cancer treatment, will be followed for survival according to the Survival 
Follow-up Period outlined below. 
 
Once disease progression is documented, participants will enter a Survival Follow-up Period. All 
participants must be followed for survival as the primary endpoint. During the Survival Follow-
up Period, data will be collected every three months regarding further cancer therapy, secondary 
malignancy, and survival status.

Screening Procedures to Assess Eligibility 
Screening evaluations will occur during a period of up to 28 days from the first screening 
evaluation to randomization unless otherwise specified. The screening period may be extended 
1-3 working days to accommodate the period ending on a weekend or holiday. The purpose of 
the screening period is to assure that subjects meet all entry criteria and that they adequately 
comprehend the protocol and its requirements. A screening log will document all participants 
who provide informed consent and are evaluated for the study. More than one clinic visit may be 
required in order to complete all screening evaluations.  
 
The screening procedure will include the following assessments: 
 
1. Collect signed and dated informed consent form. Provide a copy of the signed informed 
consent form to the participant. 
 
2. Document disease history to include: 
• Histological diagnosis of urothelial carcinoma and documentation of mixed 
histology as required.  
• Date of initial diagnosis.  
• TNM stage at diagnosis. 
• Prior administration of all cancer therapy for bladder cancer including 
intravesicular, neo-adjuvant or adjuvant therapy, surgery, radiation therapy, 
hormonal therapy, chemotherapy, biologics and experimental agents. 
 
3. Document demographics, concurrent illnesses, and medical history including significant 
historical events or findings and any pre-existing conditions. 
 
4. Conduct complete physical examination and obtain weight and height, calculate BSA

5. Assess vital signs (blood pressure, heart rate, and temperature).  
 
6. Document ECOG performance status (see Appendix B). 
 
7. Obtain chest/abdomen/pelvic CT scans (CT abdomen preferred, but MRI abdomen 
acceptable especially for participants with increased risk of contrast-related nephropathy 
or other contraindications) plus bone scan, and any other imaging studies, as 
appropriate, for disease assessment. (A brain scan is not mandated by the study unless 
the participant has signs or symptoms of CNS disease). Baseline and subsequent 
imaging must be by the same type of procedure (e.g., CT/MRI scan/bone scan) 
whenever possible. Participants with any type of scan performed as standard of care 
prior to consent for this study within 28 days of study enrollment that is available at the 
same facility where subsequent scans will be performed will NOT be required to have 
repeat scans unless they have developed new signs or symptoms of disease. CT scans 
should be performed per RECIST v1.1 criteria (see Appendix A). 
 
8. Record all sites of disease at baseline using RECIST v1.1. 
 
9. Collect approximately 35 mL blood as follows: 
 
a. 5 mL anticoagulated blood for hematology to include: 
• WBC 
• hemoglobin 
• absolute neutrophils and lymphocytes 
• platelet count 
 
b. 5 mL blood for serum chemistries to include:  
• electrolytes (sodium, potassium, chloride, CO2, calcium and phosphorus) 
• serum creatinine  
• BUN 
• SGOT (AST) and SGPT (ALT) 
• alkaline phosphatase  
• total bilirubin

Stratification Factors and Randomization Process Prior to Initiating Study 
Treatment 
 
Randomization will take place following completion of the screening evaluations and eligibility 
assessment (See Section 5.5). Stratification factors will be employed in randomization in order to 
minimize between-arm assignment imbalance. Randomization cannot occur without adequate 
data for the following stratification factors: 
 
1) Time from prior systemic chemotherapy (< 3 vs.  3 months). Time from prior systemic 
chemotherapy is defined as the date of last chemotherapy dose to the date of randomization 
and 3 months is defined as 90 days. 
 
2) Number of adverse prognostic risk factors prior to randomization (i.e., “Bellmunt criteria,” 
which include ECOG performance status > 0, hemoglobin <10 g/dL, and presence of liver 
metastases [0 versus 1-3 risk factors])37 
 
(3) Within the strata, participants will be randomly assigned with equal probability to either 
the investigational arm (Arm A: docetaxel /OGX-427) or the control arm (Arm B: docetaxel).  
 
5.7 
OGX-427 Administration During Loading Dose Period, Arm A Participants Only 
 
For Arm A participants only, three separate administrations of OGX-427 will be given during 
the Loading Dose Period. This period allows for variations in the treatment schedule due to clinic 
visits, weekends, and holidays. There must be at least one “non-infusion” day between each 
administration during the Loading Dose Period, and between the last loading dose and Day 1 of 
Cycle 1. More than one day can separate administrations, provided that all 3 doses are 
administered within the 9 days. A maximum of 7 days between the 3rd loading dose and Cycle 1, 
Day 1 is allowed.  An example of a schedule would be to give the three loading dose 
administrations of OGX-427 on Monday, Wednesday, and Friday with Day 1, Cycle 1 starting 
on the following Monday. The day prior to Day 1 of Cycle 1 (identified as Day 0) should be a 
“no treatment” day (e.g., Sunday in the above example). 
 
Additional Procedures Prior to Loading Dose 1 
• Update concurrent illnesses prior to first loading dose. 
 
• Collect approximately 20 mL blood as follows: 
a. 5 mL anticoagulated blood for hematology to include: 
• WBC 
• hemoglobin 
• absolute neutrophils and lymphocytes 
• platelet count

• electrolytes (sodium, potassium, chloride, CO2, calcium and 
phosphorus) 
• serum creatinine  
• BUN 
• SGOT (AST) and SGPT (ALT) 
• alkaline phosphatase  
• total bilirubin  
• LDH  
• albumin 
• uric acid 
 
NOTE: Samples for hematology and chemistry local laboratory testing not required if performed 
within 14 days of the first loading dose. 
 
c. 5-10 mL of blood for serum Hsp27 and other exploratory biomarker proteins 
(see the SPM for detailed collection and central lab shipping guidelines). 
 
• Only if missed during Screening (see Section 5.5): Collect 20 mL of 
blood for CTC capture and analysis:10 mL in a CellSave Preservation 
Tube, 10 mL in an EDTA-coated (purple top) tube (see the SPM for 
detailed collection and central lab shipping guidelines). 
 
Prior to Initiating the OGX-427 Loading Dose Infusions: 
 
1. Participants should be premedicated 30-90 minutes  prior to each of the three loading 
doses to reduce the risk and severity of infusion reactions with a minimum of the 
following (unless participant is intolerant):

b. an H2 antagonist (ranitidine 50 mg or H2 antagonist equivalent) 
 
Should a participant manifest a grade 2 or greater AE during or subsequent to an infusion 
reaction to OGX-427 despite the above premedications, treatment with steroids is recommended. 
Should the need for steroid treatment occur on more than 2 occasions, the participant should 
receive prophylaxis with steroids throughout OGX-427 therapy. 
 
2. Infuse OGX-427 over approximately 2 hours per institutional standards, preferably 
using an infusion pump, on each of the 3 non-sequential days within the 9-day Loading 
Dose Period.

participant’s status that might warrant a clinic visit for further assessment. Document the phone 
call. 
 
5.9 
OGX-427 Maintenance Administration, Arm A Participants Only 
 
Arm A participants who have completed all 10 cycles of docetaxel, or those who are removed 
from docetaxel due to toxicity, have completed disease assessments after at least 2 cycles, and do 
not have disease progression or toxicity related to OGX-427, should continue weekly OGX-427 
infusions as maintenance treatment until disease progression or unacceptable toxicity. 
 
1. Administer premedications 30-90 minutes prior to each OGX-427 infusion to reduce the risk 
of infusion reactions (unless participant is intolerant):  
• an antihistamine (diphenhydramine 25-50 mg or equivalent antihistamine)  
• an H2 antagonist (ranitidine 50 mg or H2 antagonist equivalent) 
 
If the participant has not manifested signs or symptoms of an infusion reaction during the 
loading doses and Cycle 1, participant may be treated in subsequent cycles without some or all of 
the pre-medications. Should Grade 2 or greater reactions occur, the participant should resume 
premedications, including dexamethasone, prior to Study Drug for the duration of the study. In 
general, if the participant has required steroid prophylaxis during treatment, it should be 
continued during the maintenance period. 
 
2. Administer OGX-427 by infusion over approximately 2 hours per institutional standards 
every week until disease progression.  
 
If any signs or symptoms occur during or immediately after the infusion, document the 
following: 
• vital signs 
• AE(s) 
 
3. Perform a limited physical exam related to signs, symptoms and concurrent illnesses 
including vital signs every 3 weeks. 
 
4. Record weight and ECOG performance status every 3 weeks.

5. AEs and concomitant medications documented weekly. 
 
6. Collect approximately 15.0 mL blood every 3 weeks as follows:  
a. 5 mL anticoagulated blood for hematology to include: 
• WBC 
• hemoglobin 
• absolute neutrophils and lymphocytes 
• platelet count  
b. 5 mL blood for serum chemistries to include:  
• electrolytes (sodium, potassium, chloride, CO2, calcium and phosphorus) 
• serum creatinine  
• BUN 
• SGOT (AST) and  SGPT (ALT) 
• alkaline phosphatase  
• total bilirubin  
• LDH 
• albumin 
• uric acid 
 
c. 5 mL of blood for serum Hsp27 (see the SPM for detailed collection and central lab 
shipping guidelines). 
 
7. Every 6 weeks, participant should have repeat chest, abdomen, and pelvic CT scans (MRI, if 
appropriate); bone scan should be repeated every 12 weeks for disease assessment if positive 
at baseline.  There is a 5 day window for scans prior to Day 1 of each cycle. All assessments 
should be performed in the same manner as the assessment at screening whenever 
possible. Refer to Section 10.3.4 for disease progression criteria. Note: If any new clinical 
signs or symptoms of disease progression have developed during any treatment cycle, repeat 
imaging as clinically indicated, preferably using the same modality as baseline, when 
appropriate, prior to the next cycle. 
 
5.10 End of Treatment Visit  
 
All participants who received at least one dose of study treatment must have an End of Treatment 
Visit at least 30 days (+ 7 days) from the last dose of study treatment.  
 
The following study procedures will be performed at the End of Treatment Visit. 
 
1. Record the reasons(s) for withdrawal from further treatment on the eCRF. 
 
2. Perform a limited physical examination related to signs, symptoms and concurrent 
illnesses and repeat of tumor measurements of palpable disease, if appropriate, including 
vital signs. 
 
3. Record weight.

4. Record ECOG performance status.  
 
5. Update and record changes in concomitant medications that occurred since the last visit 
through 30 days after the last dose of study treatment. 
 
6. Update and record adverse events that occurred since the last visit through 30 days after 
the last dose of study treatment. NOTE: All SAEs and Grade 3 or higher adverse events 
and concomitant medications that are ongoing at the end of study treatment must be 
followed until each event resolves or is assessed as chronic. 
 
7. Any participant who does not have documented disease progression must have chest, 
abdomen and pelvic CT scans (CT preferred, but MRI acceptable) and any other imaging 
studies performed at baseline, using the same technology as the screening scans, for 
disease status (if not performed within the last 6 weeks [42 days]). If the bone scan was 
positive at baseline, it should be repeated if not performed within the last 12 weeks. The 
schedule for subsequent scans during the Disease Progression Follow-up Period will be 
maintained (i.e. the assessment frequency does not ‘reset’ starting from the EOT visit).  
 
8. Collect approximately 15 mL of blood as follows:  
 
a. 5 mL anticoagulated blood for hematology to include: 
• WBC

5.11 Disease Progression Follow-up Period (Every 6 Weeks [± 7 Days]) 
 
All participants without documented disease progression who completed study treatment or 
withdrew from study treatment for a reason other than disease progression will have imaging 
evaluations during the Disease Progression Follow-up Period until disease progression is 
documented. The evaluation schedule start will be 6 weeks from the last on treatment assessment 
to maintain the every 6 weeks schedule.  
 
The following evaluations will be performed every 6 weeks (± 7 days) unless otherwise 
specified: 
 
1. Conduct limited physical examination related to signs, symptoms, and concurrent 
illnesses and including repeat measurements of palpable disease, if appropriate. 
2. Record ECOG performance status. 
3. Repeat chest, abdominal and pelvic CT scans (CT preferred, MRI acceptable) every 6 
weeks. If the bone scan was positive at baseline, it should be repeated if not performed 
within the last 12 weeks.  
 
NOTE: If any new clinical signs or symptoms of disease progression have developed, repeat 
imaging as clinically indicated, preferably using the same modality as baseline, when 
appropriate, for assessment of disease progression. 
 
If the participant withdraws from study treatment for a reason other than disease progression and 
initiates other cancer treatment, discontinue follow-up for progression and follow for survival 
status only according to the Survival Follow-up Schedule below. 
 
5.12 Survival Follow-up (Every 3 Months[± 7 Days]) 
 
Following disease progression, participants will be followed every 3 months for subsequent 
anticancer therapy, secondary malignancies, and survival status. Information on the start date, 
type and duration of any subsequent anticancer therapy will be collected. This follow-up may be 
accomplished through routine clinic follow-up visits, telephone contact with the participant or 
through contact with the primary practitioner or caregiver. 
 
5.13 General Concomitant Medication and Supportive Care Guidelines 
 
5.13.1 
Premedications for OGX-427  
 
Participants should be premedicated with a minimum of the following at 30-90 minutes prior to 
each OGX-427 infusion in an attempt to reduce the risk and severity of infusion reactions (unless 
participant is intolerant): 
• an antihistamine (diphenhydramine 25-50 mg or equivalent antihistamine)  
• an H2 antagonist (ranitidine 50 mg or H2 antagonist equivalent) 
 

HCRN GU12-160                                                                                                               Version 7 Date 15OCT2014 
Confidential
51
Should a participant manifest a grade 2 or greater AE during or subsequent to an infusion 
reaction to OGX-427 despite the above premedications, treatment with steroids is recommended. 
Should the need for steroid treatment occur on more than 2 occasions, the participant should 
receive prophylaxis with steroids throughout OGX-427 therapy. 
 
If the participant has not manifested signs or symptoms of an infusion reaction during the 
loading doses and Cycle 1, participant may be treated in subsequent cycles without some or all of 
the premedications. Should Grade 2 or greater reactions occur, the participant should resume 
premedications, including dexamethasone, prior to Study Drug for the duration of the study.  
 
5.13.2 
Premedication for Docetaxel Chemotherapy  
All participants should be premedicated with corticosteroids in order to reduce the incidence and 
severity of fluid retention as well as the severity of hypersensitivity reactions. Refer to 
institutional standards for recommendations on premedication prior to docetaxel chemotherapy.  
 
5.13.3 
Growth Factors and Blood Products 
Filgrastim (G-CSF), pegfilgrastim, sargramostim (GM-CSF), erythropoietin, and other growth 
factors may be utilized at the discretion of the Investigator. All growth factors must be recorded 
on the concomitant medication eCRF. American Society of Clinical Oncology (ASCO) 
guidelines should be followed. 
 
The use of oprelvekin (IL-11, Neumega) is strongly discouraged. 
All blood product transfusions will be at the discretion of the Investigator and must be recorded 
on the concomitant medication eCRF. 
 
5.13.4 
Anticoagulation 
Participants on warfarin should have their international normalized ratio (INR) checked 
frequently to maintain a level between 2 and 3.  
 
The use of low molecular weight heparin (LMWH) in participants with severe renal dysfunction 
will prolong the elimination half-life of LMWH and may increase bleeding risk. Renal function 
should be monitored and the dose of LMWH adjusted as required. 
 
5.13.5 
Anticancer Therapies 
Treatment with any anticancer therapy, including radiation therapy, is not allowed while the 
participant is on study. Once the participant has documented disease progression or has 
terminated study treatment, further therapy is at the discretion of the Investigator. All anticancer 
therapy must be documented, including date of initiation. 
 
5.14 Duration of Study Treatment 
Duration of study treatment will depend on evidence of disease progression and tolerance. Study 
treatment may continue until one of the following criteria applies: 
• Disease progression or death 
• Intercurrent illness that prevents further administration of treatment 
• Unacceptable adverse event(s) 

HCRN GU12-160                                                                                                               Version 7 Date 15OCT2014 
Confidential
52
• More than a 4 week delay in any study treatment for any reason (i.e., 5 consecutive 
weekly doses of OGX-427 missed during chemotherapy or maintenance treatment). If 
there is more than a 4 week delay in docetaxel chemotherapy, the participant should be 
removed from further docetaxel chemotherapy and if receiving OGX-427 may continue 
on maintenance therapy (Refer to Section 5.9 for maintenance criteria) 
• Inability or unwillingness to comply with the study treatment requirements 
• Participant withdrawal from the study 
• General or specific changes in the participant's condition that render the participant 
unacceptable for further treatment in the opinion of the treating investigator 
• Closure of the study by the drug sponsor, OncoGenex Technologies, or Regulatory 
Authorities 
•  
For Arm A participants, the maximum duration of study treatment could include 9 days for 
loading doses, 10 cycles at 3 weeks per cycle, and maintenance treatment until disease 
progression or unacceptable toxicity. 
 
For Arm B participants, the maximum duration of study treatment could include 10 cycles at 3 
weeks per cycle, for a total of approximately 30 weeks. 
 
5.15 Duration of Follow Up  
Participants will be followed for disease progression every 6 weeks (± 7 days) until disease 
progression is documented and then for survival status every 3 months until death. The exception 
is follow up for participants who discontinue study therapy for reasons other than progression 
and initiate other cancer treatment. They will be followed for survival status only according to 
the Survival Follow-up Schedule above. 
 
NOTE: Participants removed from study for unacceptable adverse events will also be followed 
for resolution or stabilization of the adverse event as well as disease progression and survival 
status.  
 
5.16 Criteria for Removal from Study Treatment  
Participants will be removed from study treatment when any of the criteria listed in Section 5.14 
applies. The reason for removal from study treatment and the date the participant discontinued 
study treatment must be documented in the study-specific electronic case report form (eCRF). 
Alternative care options will be discussed with the participant. Participants will be followed as 
described in Sections 5.11 and 5.12. 
 
5.17 Criteria for Removal from Study Participation  
Participants have the right to withdraw consent for further trial participation at any time without 
having to specify the reason. The data recorded up to the time point of withdrawal will continue 
to be evaluated in the trial. The investigator should ask the participant for his/her consent to 
continue to collect information on survival status.  
 
6. EXPECTED TOXICITIES AND DOSING DELAYS/DOSE MODIFICATIONS  
Dosing for docetaxel will be based on the participant’s height and actual body weight. Dosing for 
OGX-427 will be fixed at 600 mg.  

HCRN GU12-160                                                                                                               Version 7 Date 15OCT2014 
Confidential
53
Dose delays and modifications will be made using the following recommendations. Toxicity 
assessments will be done using the revised NCI Common Terminology Criteria for Adverse 
Events (CTCAE) version 4.0 which is identified and located on the CTEP website at: 
http://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.htm.  
 
Treatment delays not made up in the same calendar week for the scheduled dose, for treatment 
Day 1 will be ‘made up’ (i.e. if treatment for Day 1 is delayed, resume with Day 1 schedule once 
toxicity has resolved).  Treatment delays not made up in the same calendar week for the 
scheduled dose, for treatment Days 8 or 15 will be ‘skipped’ and not made up (i.e., if treatment 
for Day 8 is delayed, resume with Day 15 schedule once toxicity has resolved). 
 
If possible, symptoms should be managed symptomatically. In the case of toxicity, appropriate 
medical treatment should be used (including anti-emetics, anti-diarrheals, etc.). 
 
All adverse events experienced by participants will be collected from the time of the first dose of 
study treatment, through the study, and until the final study visit. Participants continuing to 
experience toxicity at the “End of Treatment Visit” may be contacted for additional assessments 
until the toxicity has resolved or is assessed as chronic. 
 
In general, the need for dose modifications will be assessed based on laboratory values and/or 
physical signs obtained within 48 hours prior to treatment on Day 1 of each cycle. Modifications 
for toxicity are defined below for infusion reactions. Some dose modifications are specific for 
docetaxel only, for OGX-427 only, or for both docetaxel and OGX-427. In general, weekly 
administration of OGX-427 will continue when a cycle is delayed for toxicity felt to be due to 
docetaxel. The dose of OGX-427 or docetaxel will not be re-escalated once the dose is reduced. 
If more than two dose reductions of either OGX-427 or docetaxel are required, treatment with 
that study medication must be discontinued. Any participant requiring a toxicity-related dose 
delay of more than 4 weeks (5 consecutive OGX-427 doses missed) from the intended day of the 
next scheduled dose, for any reason,  must be discontinued from study treatment. If there is more 
than a 4 weeks delay in docetaxel chemotherapy, the participant should be removed from further 
docetaxel chemotherapy. If the toxicity is not perceived as related to OGX-427, the patient may 
begin the OGX-427 maintenance phase, provided disease assessments were completed after at 
least 2 cycles of chemotherapy.  Participants who discontinue study treatment will have an “End 
of Study Treatment” assessment (Section 5.10) and then enter the “Disease Progression Follow-
up Period” until disease progression (Section 5.11). 
 
The reason for modifying the dose of any study treatment (OGX-427 or docetaxel) must be 
recorded in the source documents and the eCRF. 
6.1 
Anticipated Toxicities 
6.1.1 Anticipated Toxicities for OGX-427  
As of the cutoff date of June 15, 2013, safety data when used as monotherapy has been compiled 
from a Phase I study (OGX-427-01) and from ongoing, open-label Phase II study, PR-01. The 
infusion reactions are based on PR-01 subjects who received 600 mg for each of 3 loading doses. 
Infusion reactions, which occur during or soon after the infusion of OGX-427, have occurred in 
approximately 67% of patients, including cytokine release syndrome. Patients were premedicated

with an H2 antagonist and antihistamine. The most common symptoms have been chills (46%), 
flushing (13%), diarrhea (20%), nausea (18%), and vomiting (10%).The majority of reactions 
occurred with the first three loading doses and during the first weekly infusions of therapy, but 
reactions have continued to occur with further infusions in some patients. Reactions may require 
treatment or prophylaxis with corticosteroids.

The risks and side effects that have been seen in patients who have been treated with OGX-427 
and docetaxel that have been felt to be possibly, probably, or definitely related to Study Drug 
are defined below.  
 
Very likely (greater than 20% of patients):  
• Infusion reactions, which occur during or soon after the infusion of OGX-427, have 
occurred in approximately 80% of patients, including cytokine release syndrome. The 
most common symptoms have been shaking chills (73%), itching (46%) and flushing 
(27%). The majority of reactions occurred with the first three loading doses and during 
the first weekly infusions of therapy, but reactions have continued to occur with further 
infusions in some patients. Reactions appear to be more frequent and more severe at 
higher doses of OGX-427 and may require treatment or prophylaxis with corticosteroids. 
In rare occasions, infusion reactions can be life threatening.  
• Prolongation of PTT (100%) which in rare circumstances could lead to serious bleeding.  
• Lymphopenia (100%) which in rare circumstances could lead to uncommon but serious 
infections.  
• Anemia (100%) which can cause tiredness, shortness of breath, and a possible need for 
red blood cell transfusions.  
• Neutropenia (91%) which can lead to serious infections. 
• Low sodium (68%) which could cause a seizure. 
• Decrease in kidney function (reversible) (50%)  
• Thrombocytopenia (50%) which could lead to an increased risk of bleeding and/or 
require platelet transfusions. 
• Fatigue/tiredness (46%)  
• Decreased liver function (reversible) (41%) 
• Nausea (36%)

6.1.2 Anticipated Toxicities for Docetaxel  
The risks and side effects observed with docetaxel when used as monotherapy in a population of 
patients previously treated with a platinum-based chemotherapy are summarized below. For 
more detailed information on docetaxel anticipated toxicities, please refer to the package insert 
for docetaxel. 
 
Myelosuppression, predominately neutropenia, is the DLT of docetaxel with a nadir at days 7-10 
and recovery by approximately day 14. CBCs with differential and platelet count should be 
monitored. 
 
Docetaxel is hepatotoxic and should be used with caution in patients with abnormal liver 
function. 
 
Docetaxel is contraindicated in patients with known hypersensitivity to docetaxel or to 
polysorbate 80. Reactions (flushing, fever, rigors, rash, hypotension, dyspnea, and/or 
bronchospasm) usually occur within the first few minutes of the first or second administrations 
and almost all occur within the first 10 minutes. Severe reactions occur in < 5% of patients. 
Patients should be closely monitored during infusions. Resuscitation equipment should be ready 
at the bedside. 
 
Fluid retention is seen in around 25-50% of patients and can be severe (ascites, pleural, or 
pericardial effusions) in around 7% of patients. 
 
All participants should receive corticosteroid premedication before docetaxel administration to 
reduce the incidence and severity of fluid retention as well as the severity of hypersensitivity 
reactions. Refer to institutional standards for recommendations on premedication prior to 
docetaxel administration.

6.2 
Dose Modifications for Toxicity 
In general the criteria for the degree of resolution for adverse events is  Grade 1 with the 
following exceptions where it is felt there are no safety concerns for retreatment in participants 
when the toxicity has resolved to  Grade 2: anemia, fatigue, asthenia, lethargy, malaise, nail 
changes, or hyperglycemia in a participant with known diabetes mellitus. 
 
6.2.1 Specific Dose Levels for Docetaxel and OGX-427 Modification 
The tables below define the specific dose level modifications for docetaxel (Table 4) and 
OGX-427 (Table 5). Subsequent sections delineate when dose modifications should occur.

6.2.2 Dose Modifications for Infusion (Allergic/Hypersensitivity) Reactions 
Infusion reactions (including fever, chills, diarrhea, rash, urticaria, erythema, pruritus, 
bronchospasm, hypotension, and anaphylaxis) can occur with the agents used in this protocol. 
For participants previously exposed, reactions to docetaxel can occur within minutes. 
 
In the event of an infusion reaction, follow the Institutional Guidelines of each site and/or the 
recommendations shown in the tables below, based on the grade of the reaction. 
 
To identify the grade of a reaction, refer to the list below adapted from the General Disorders and 
Administration Site Conditions section of the NCI CTCAE Version 4.0: 
 
Grade 1:  Mild transient reaction; infusion interruption not indicated; intervention not indicated.  
 
Grade 2:  Therapy or infusion interruption indicated but responds promptly to symptomatic 
treatment (e.g., antihistamines, NSAIDS, narcotics, IV fluids indicated for  24 hours).  
 
Grade 3:  Prolonged (e.g., not rapidly responsive to symptomatic medication and/or brief 
interruption of infusion); recurrence of symptoms following initial improvement; hospitalization 
indicated for other clinical sequelae Note: any infusion that is interrupted and not resumed 
within the visit will be considered a Grade 3 reaction.

Grade 4: Life-threatening consequences; urgent intervention indicated. 
 
6.2.2.1 Dose Modifications for OGX-427 Infusion Reactions  
During the Loading Dose Period, the dose of OGX-427 will be 600 mg. There will be no dose 
reductions of OGX-427 during the Loading Dose Period for infusion reactions. Grade 3 reactions 
have been uncommon. Should a grade 3 or 4 reaction occur during the loading dose period or at 
Cycle 1 Day 1, OGX-427 can be held until the AE is  grade 1.  
 
Should a participant manifest a grade 2 or greater AE during or subsequent to an infusion 
reaction of OGX-427 despite the above premedications, treatment with steroids is recommended. 
Should the need for steroid treatment occur on more than 1 occasion, the participant should 
receive prophylaxis with steroids throughout OGX-427 therapy prior to any dose modifications 
(see Section 5.13.1). 
 
The tables below define the dose modifications for infusion reactions occurring during and 
following the Loading Dose Period. 
Table 6: Dose Modifications for OGX-427 Infusion Reactions  
Toxicity
Dose Modification 
Grade 1 infusion reaction 
Slow the rate of infusion of the OGX-427 until resolution of 
symptoms, then resume at the planned infusion rate. 
Grade 2 or 3 infusion reaction 
Stop the infusion. Give steroids (e.g., dexamethasone 8 mg IV), 
diphenhydramine 50 mg IV, and/or an H2 antagonist (e.g. Ranitidine 
50 mg IV) after consultation with the attendant physician. Resume 
after recovery of symptoms at a slower rate, and then increase 
incrementally toward the initial rate. If the reaction reoccurs, stop the 
infusion and do not administer the remaining volume.  
Should a grade 2 or 3 infusion reaction recur in the presence of steroid 
prophylaxis, reduce the OGX-427 by one dose level for all subsequent 
doses. 
Grade 4 infusion reaction 
Stop the infusion. Remove the participant from study treatment.

6.2.2.3 Docetaxel Dose Modifications for Hematology Toxicity 
G-CSF and other growth factors (except oprelvekin) may be utilized at the discretion of the 
Investigator and should follow ASCO guidelines. The following table delineates how to modify 
or hold the dose of docetaxel based on the hematology results and clinical findings on Day 1 of 
each cycle.  
NOTE: OGX-427 will not be held or modified for hematological toxicity.

Toxicity 
Dose Modification  
On Day 1 of a cycle: 
ANC ≥1.5 x109 cells /L and platelet count 
≥100 x 109/L  
100% of present docetaxel dose  
On Day 1 of a cycle: 
ANC <1.5 x109 cells /L  
and/or 
 platelet count <100 x 109/L 
Delay Docetaxel. Continue to administer OGX-427. Repeat 
CBC weekly 
If ANC resolves to ≥1.5 x109 cells /L and/or platelet count 
≥100 x 109/L, resume docetaxel at 100% of present dose 
If docetaxel is delayed for more than 1 week (but less than 4 
weeks), resume docetaxel at one lower dose level following 
the recovery of the ANC to ≥1.5 x109 cells /L and the 
platelet count to ≥100 x 109/L 
If treatment is delayed for more than 4 weeks, the participant 
should be removed from further docetaxel chemotherapy 
(and proceed to maintenance therapy, if applicable) 
Any time during the previous cycle for one of 
the following: 
Grade 3 febrile neutropenia (defined as an 
ANC <1.0 x 109 cells/L and a single 
temperature >38.3°C or a sustained 
temperature of >38°C for more than an 
hour) 
Documented infection with grade 3 
neutropenia (defined as an ANC <1.0 x 109 
cells/L) 
Grade 4 neutropenia (defined as an ANC 
<0.5 x 109 cells/L lasting more than 5 days 
Grade 4 thrombocytopenia (platelet count 
<25 x 109/L) lasting for more than 5 days 
Delay treatment with docetaxel until improvement of 
symptoms and resolution of the ANC to ≥1.5 x109 cells /L 
and platelet count to ≥100 x 109/L. Weekly treatment with 
OGX-427 should continue.  
Decrease docetaxel by one dose level for all subsequent 
cycles.  
With recurrence of any of these toxicities, the participant 
should be removed from docetaxel chemotherapy (and 
proceed to maintenance therapy, if applicable). 
Any time during the previous cycle for one of 
the following: 
Grade 4 febrile neutropenia or infection 
with grade 4 neutropenia (both defined as 
septic shock) 
Thrombocytopenic hemorrhage (gross not 
occult bleeding) associated with a platelet

6.2.2.4 Docetaxel Dose Modifications for Neurotoxicity 
For grade 4 neurotoxicity (life threatening), the participant should be removed from study 
treatment. 
 
For grade 3 neurotoxicity, docetaxel should be held until toxicity resolves to ≤ grade 1. Resume 
docetaxel at a dose reduction of one level. 
 
6.2.2.5 Docetaxel Dose Modifications for Fluid Retention 
There are no dose reductions for fluid retention. Participants should be treated with salt 
restrictions and diuretics. More aggressive therapy depends on the clinical situation. In severe 
situations, the Investigator, with the participant, should determine if it is in the participant’s best 
interest to continue or discontinue study treatment. 
 
6.2.2.6 Docetaxel Dose Modifications for Mucocutaneous Toxicity (Skin and Mucous 
Membranes) 
 
For grade 4 mucocutaneous toxicity (life-threatening), the participant should be removed from 
study treatment. 
 
For grade 3 mucocutaneous toxicity present on Day 1 of a cycle, docetaxel should be held until 
toxicity resolves to ≤ grade 1. Resume docetaxel at a dose reduction of one level.  
 
If the grade 3 mucocutaneous toxicity does not resolve within 4 weeks, the participant should be 
removed from docetaxel treatment. 
 
6.2.2.7 Docetaxel Dose Modifications for Diarrhea 
In the case of grade 4 (life threatening) diarrhea, the participant should be removed from study 
chemotherapy treatment but may continue on OGX-427 as maintenance therapy (Arm A only). 
In the case of grade 3 diarrhea (≥ 7 stools per day over baseline; incontinence; need for IV fluids 
> 24 hours; or hospitalization), docetaxel should be held until resolution to ≤ grade 1 and the 
participant should receive prophylactic anti-diarrhea therapy in subsequent cycles.  
 
If grade 3 diarrhea recurs despite maximal prophylactic treatment (e.g., loperamide, 
diphenoxylate hydrochloride with atropine, octreotide), the participant should be removed from 
docetaxel treatment.

hypomagnesemia]), delay docetaxel therapy until the toxicity resolves to  grade 1. Once the 
toxicity resolves to  grade 1, resume docetaxel. If the toxicity was related to chemotherapy, 
resume docetaxel at a dose reduction of one level.. Weekly administration of OGX-427 should 
continue unless the toxicity is felt to be related to OGX-427. The dose of OGX-427 should be 
lowered by one dose level only if the toxicity is felt to be possibly related to OGX-427. If the 
toxicity does not resolve within 4 weeks, the participant should be removed from chemotherapy 
(and from OGX-427 if the toxicity if felt to be related to OGX-427). Otherwise the participant 
will continue on maintenance therapy, if applicable. 
 
For grade 4 life threatening toxicities, participants should be removed from study therapy. 
 
 6.2.5 Onset of either  Grade 2 Motor Neuropathy or  Grade 2 Muscle Weakness 
Any onset of  Grade 2 motor neuropathy or  Grade 2 muscle weakness should be evaluated by 
EMG to rule out the possibility of chronic inflammatory demyelinating polyneuropathy (CIDP). 
With a diagnosis of CIDP the patient should be discontinued from study treatment.

7.2.6 Availability 
Taxotere® is commercially available from sanofi-aventis U.S. LLC. 
 
7.2.7 Preparation and Administration 
Please follow package insert for specific instructions.   
 
1-vial Taxotere® (docetaxel) Injection Concentrate requires NO prior dilution with a diluent 
and is ready to add to the infusion solution. Use only a 21 gauge needle to withdraw 
TAXOTERE from the vial because larger bore needles (e.g., 18 and 19 gauge) may result in 
stopper coring and rubber particulates. 
1. TAXOTERE vials should be stored between 2 and 25°C (36 and 77°F). If the vials 
are stored under refrigeration, allow the appropriate number of vials of 
TAXOTERE Injection Concentrate vials to stand at room temperature for 
approximately 5 minutes before use. 
2. Aseptically withdraw the required amount of TAXOTERE injection concentrate 
(20 mg docetaxel/ mL) with a calibrated syringe and inject into a 250 mL infusion 
bag or bottle of either 0.9% Sodium Chloride solution or 5% Dextrose solution to 
produce a final concentration of 0.3 mg/mL to 0.74 mg/mL.  
If a dose greater than 200 mg of TAXOTERE is required, use a larger volume of 
the infusion vehicle so that a concentration of 0.74 mg/mL TAXOTERE is not 
exceeded.  
3. Thoroughly mix the infusion by gentle manual rotation. 
4. As with all parenteral products, TAXOTERE should be inspected visually for 
particulate matter or discoloration prior to administration whenever the solution 
and container permit. If the TAXOTERE dilution for intravenous infusion is not 
clear or appears to have precipitation, it should be discarded. 
 
The Taxotere® dilution for infusion should be administered intravenously over approximately 
1-hour per institutional standards, under ambient room temperature (below 25°C) and lighting 
conditions. 
 
1-vial Taxotere® Injection Concentrate is a sterile, non-pyrogenic, pale yellow to brownish-
yellow solution at 20 mg/mL concentration. Each mL of 1-vial Taxotere® contains 20 mg 
docetaxel (anhydrous) in 0.54 grams polysorbate 80 and 0.395 grams dehydrated alcohol 
solution.1 
 
Taxotere® is supplied in a single use clear glass vial with a red flip-off cap for the 80-mg vial 
and a green cap for the 20-mg vial. Each vial is provided in a blister pack in a single carton.1 
Contact of the Taxotere concentrate with plasticized PVC equipment or devices used to 
prepare solutions for infusion is not recommended. To minimize participant exposure to the 
plasticizer DEHP (di-2-ethylhexyl phthalate), which may be leached from PVC infusion bags 
or sets, the final Taxotere® dilution for infusion should be stored in bottles (glass, 
polypropylene) or plastic bags (polypropylene, polyolefin) and administered through 
polyethylene-lined administration sets.1

8. CORRELATIVE/SPECIAL STUDIES  
HCRN will provide kits and shipping supplies for tissue and serum collected for assays 
evaluating Hsp27 and other biomarker proteins. University of Miami will provide kits and 
shipping supplies for peripheral blood collected for CTC assays.  
 
8.1 
Blood Collection for Assays Evaluating Hsp27  
Blood for serum assays for evaluating Hsp27 will be collected (at screening, prior to the first 
loading dose (Arm A only), pre-dose Day 1 of each cycle, every 3 weeks during maintenance 
(Arm A only) and at the End of Treatment visit), processed at the local site, and shipped to a 
central laboratory for analysis. Refer to the SPM for collection, processing, labeling and central 
lab shipping instructions.  Baseline and changes in Hsp27 protein levels will be explored in 
relation to participant outcomes as a possible prognostic and predictive biomarker for OGX-427 
biologic activity.  The purpose of assessing changes in other proteins (e.g., other Hsp family 
members and their client proteins) is to evaluate their usefulness as biomarkers that may have 
prognostic or predictive factors in urothelial cancer.  
 
8.2 
Archived Tissue for Associations Between Tumor Hsp27 and Clinical Outcomes 
Where available, archived FFPE primary and metastatic tumor tissue will be obtained from 
registered study participants  Refer to the SPM for collection, processing, labeling and central lab 
shipping instructions. Associations between primary tumor Hsp27 IHC staining intensity and 
clinical outcomes will be performed.   Analysis of additional biomarkers of interest may also be 
performed based on tumor tissue availability.  All analyses will be hypothesis generating.  As 
such, no formal sample size calculations have been performed for this portion of the correlative 
analyses.  
 
We are requesting patient consent to store samples from archival tumor in our already 
established repository for possible future IRB approved research to determine if somatic 
mutations are associated with treatment outcome.  
 
8.3 
 Blood Collection for CTC Assays  
Peripheral blood for circulating tumor cell (CTC) analysis will be collected at Screening and pre-
dose on Day 1 of Cycles 2, 3 and 5.  If sample is missed at Screening, it should be collected pre-
dose at loading dose 1 for Arm A and pre-dose Day 1 Cycle 1 for Arm B. Refer to the SPM for 
collection, processing, labeling and central lab shipping instructions. 
 
8.4   Blood Collection for Other Relevant Proteins 
Blood for other relevant proteins will be collected prior to first loading dose (Arm A only), pre-
dose on Day 1 of Cycle 1 (Arm B only), pre-dose on Day 1 of Cycles 3 and 5. Refer to the SPM 
for collection, processing, labeling and central lab shipping instructions.

Study Calendar Footnotes: 
1Screening evaluations will be completed within a 28-day period + 3 days (i.e. from the first screening evaluation to randomization) 
unless otherwise specified.  
2Participants will be randomly assigned with equal probability to one of two arms: Arm A: docetaxel plus OGX-427; Arm B: 
docetaxel alone. Participants must receive their first dose of Study Drug within 5 days of randomization. 
3For participants in Arm A, three separate administrations of OGX-427 (600 mg OGX-427) will be given IV over 2 hours per 
institutional standards.  The 3 loading doses must be administered with at least one “non-treatment” day between each dose. To allow 
for holidays and clinical availability, a maximum of 9 days is allowed to complete the Loading Dose period.  There must also be a 
minimum of 1 and maximum of 7 days between the 3rd loading dose and Cycle 1, Day 1. During Cycles 1-10, OGX-427 will be 
administered at a dosage of 600 mg given IV over 2 hours per institutional standards on Days 1, 8, and 15 of each cycle. Arm A 
participants who have completed all 10 cycles of docetaxel, or have received at least 2 cycles of docetaxel with weekly OGX-427, and 
have discontinued study treatment without documented disease progression and not due to toxicity related to OGX-427 may continue 
to receive OGX-427 at the 600 mg dosage as maintenance until disease progression or unacceptable toxicity. 
4Participants in Arm A who have completed all 10 cycles of docetaxel, or who have received at least 2 cycles of docetaxel with 
weekly OGX-427 infusions and have discontinued study treatment without documented disease progression and not due to toxicity 
related to OGX-427 should continue weekly OGX-427 infusions as maintenance until disease progression or unacceptable toxicity. 
5Off Treatment Follow-up Period: evaluations should continue every 6 weeks (± 7 days) until disease progression. 
6Participants who have documented disease progression will be followed every 3 months (± 7 days) for documentation of anticancer 
therapy, secondary malignancies, and survival status. Survival follow-up can be accomplished by routine clinic visits, telephone 
contact with the participant, or through the primary practitioner or caregiver. 
7Disease history, including histological diagnosis of urothelial carcinoma and documentation of mixed histology as required, date of 
initial diagnosis, TNM stage at diagnosis and prior administration of all cancer therapy for bladder cancer including intravesicular, 
neo-adjuvant or adjuvant therapy, surgery, hormonal therapy, radiation, chemotherapy, biologics, and experimental agents. 
8Update concurrent illnesses prior to first loading dose for Arm A. Update concurrent illnesses prior to first dose Cycle 1 Day 1 for 
Arm B. 
9 Perform complete physical examination at Screening (including tumor measurements of palpable disease, if appropriate). A limited 
PE examination related to signs, symptoms and concurrent illnesses is appropriate during the study.  
10Weight is not required during the Off Treatment Follow-up Period.

17Serum for measurement of Hsp27 will be collected and shipped to a Central Laboratory where analysis will be performed. Blood 
should be drawn at screening, prior to the first loading dose (Arm A only), on pre-dose Day 1 of each cycle, every three weeks during 
maintenance therapy (Arm A only), and at the End of Treatment Visit (See SPM for collection processing and shipping instructions) 
18.Serum for other protein analysis will be collected at prior to first loading dose (Arm A only), pre-dose day 1 cycle 1 (Arm B only), 
pre-dose day 1 cycle 3 and 5. (See SPM for collection processing and shipping instructions) 
19Blood for circulating tumor cell (CTC) capture and analysis will be collected and shipped to University of Miami (UM). Blood 
should be drawn at screening and pre-dose on Day 1 of Cycles 2, 3 and 5. (See SPM for collection processing and shipping 
instructions). If blood for CTC is missed at Screening, collect pre-dose at loading dose 1 for Arm A and pre-dose Day 1 Cycle 1 for 
Arm B. 
20Obtain chest/abdomen/pelvic CT scans (CT preferred, but MRI acceptable especially for participants with increased risk of contrast 
related nephropathy or other contraindications) plus bone scan, and any other imaging studies, as appropriate, for disease assessment 
including palpable disease measured during the physical examination. (A brain scan is not mandated by the study unless the 
participant has signs or symptoms of CNS disease). Preferably, the baseline and subsequent imaging will be by the same type of

procedure (e.g. CT vs. MRI scan) whenever possible. Participants with any type of scan performed as standard of care prior to consent 
for this study within 28 days of study enrollment that is available at the same facility where subsequent scans will be performed will 
NOT be required to have repeat scan unless they have developed new signs or symptoms of disease. CT scans should be performed 
per RECIST Criteria v1.1. CT of chest/abdomen/pelvis (CT preferred, but MRI acceptable especially for participants with increased 
risk of contrast related nephropathy or other contraindications) will be performed at baseline, every 6 weeks until disease progression, 
and with any sign or symptom of new or worsening disease. A bone scan is required at baseline and, if positive, every 6 weeks during 
the first 4 cycles of treatment (i.e., at the end of Cycles 2 and 4) every 12 weeks thereafter until disease progression (i.e., at the end of 
Cycle 8, at End of Treatment, and during maintenance with OGX-427 [Arm A only]), and with any sign or symptom of new or 
worsening bone disease or increase in alkaline phosphatase felt to be of bone origin. If new clinical signs or symptoms of disease 
progression have developed, repeat imaging as clinically indicated, preferably using the same modality as baseline, when appropriate.  
There is a 5 day window for scans prior to Day 1 of each cycle while patients are on treatment.  There is a 7 day window for scans at 
EOT, disease progression/follow-up and survival. 
21Participants should be pre-medicated at 30-90 minutes prior to each of the three loading doses and Cycle 1, Day 1, 8 and 15 with an 
antihistamine, H2 antagonist and if needed corticosteroid. If the participant has not manifested signs or symptoms of an infusion 
reaction during the loading doses and Cycle 1, participant may be treated in subsequent cycles without some or all of the 
premedications. Should Grade 2 or greater reactions occur, the participant should resume premedications, including dexamethasone, 
prior to Study Drug for the duration of treatment. See Section 5.13.1 for details. 
22Adverse events to be graded using NCI CTCAE 4.0. The adverse event reporting period begins from the initiation of the first dose of 
Study Drug until 30 days after the last dose of Study Drug. All SAEs and Grade 3 or higher AEs that are ongoing at the end of study 
treatment need to be followed until each event resolves or is assessed as chronic. Beginning Cycle 2, (for Arm B only) contact 
participant by telephone to assess for any change in the participant’s status that might warrant a clinic visit for further assessment. 
Document the phone call. 
23Concomitant Medications should be documented from the screening visit until 30 days after the last dose of Study Drug. After 30 
days following the last dose of Study Drug record only concomitant medications associated with SAEs and Grade 3 or higher adverse 
events that have not resolved. 
24 Where available, archived FFPE primary and metastatic tumor tissue will be collected from registered participants and shipped to 
HCRN. Analysis for associations between primary tumor Hsp27 IHC staining intensity and clinical outcomes will be performed.  
Analysis of additional biomarkers of interest may also be performed based on tumor tissue availability.  (See SPM for collection 
processing and shipping instructions)

10. MEASUREMENT OF EFFECT  
Although response is not the primary endpoint of this trial, participants with measurable 
and/or non-measurable disease will be assessed by RECIST v1.1.  For the purposes of this 
study, participants should be reevaluated every 6 weeks.  
 
10.1 Antitumor Effect on Measurable and Non-measurable Disease (RECIST v1.1) 
For the purposes of this study, participants should be re-evaluated for response every 6 weeks. 
Response and progression will be evaluated in this study using the new international criteria 
proposed by the Response Evaluation Criteria in Solid Tumors (RECIST v1.1).38 Changes 
in the diameter (unidimensional measurement) of the tumor lesions are based on the 
RECIST v1.1 criteria as described below for both measurable and non-measurable disease. 
 
10.1.1 
Measurable Disease (Target Lesions) 
Lesions must be able to be accurately measured in at least one dimension with the longest 
diameter ≥ 10 mm using CT scans or MRI. For pathological lymph nodes to be measureable, a 
node must by  15 mm in the short axis. All measurements should be taken and recorded in 
millimeters. 
 
Lesions in previously irradiated areas should not be selected as target lesions, unless there has 
been demonstrated progression in the lesion. 
 
CT scans with contrast (unless contraindicated i.e. especially for participants with increased risk 
of contrast related nephropathy) should be performed with slice thickness no greater than 5 mm. 
The same method of assessment should be used at baseline and during follow-up assessments for 
each lesion, i.e., conventional vs. spiral CT or MRI, whenever possible. 
 
At baseline, measurable lesions representing overall tumor burden up to a maximum of 2 lesions 
per organ and 5 lesions in total should be identified as “target lesions” and recorded and 
measured. Lesions which are unsuitable for accurate, repeated measurements should not be 
selected as target lesions. A sum of the diameters (long axis for non-nodal and short axis for 
nodal lesions) of all target lesions at baseline will be calculated and reported as the baseline sum 
diameter. This will be used as reference to characterize disease progression. Multiple target 
lesions should be reported consistently on the eCRFs in the same lesion order (i.e., with the same 
number) and with the same location descriptor on each subsequent examination. 
 
10.1.2 
Non-Measurable Disease (Non-Target Lesions) 
All other lesions or sites of disease, including lesions on bone scan, should be identified as 
“non-target lesions” and should also be recorded at baseline. This includes small lesions (longest 
diameter <10 mm or pathological lymph nodes with 10 to <15 mm short axis) or measurable 
lesions in excess of 2 per organ or 5 in total. Measurements of these lesions are not required, but 
each lesion must be recorded as “present”, “absent”, or “new” at the time of each tumor 
evaluation. Multiple non-target lesions should be reported consistently on the eCRFs in the same 
lesion order (i.e., with the same number) and with the same location descriptor on each 
subsequent examination.

77 
10.2 Methods for Evaluation of Measurable Disease 
All measurements should be taken and recorded in metric notation, using a ruler, calipers, 
or digital measurement tool. All baseline evaluations should be performed as closely as 
possible to the beginning of treatment and never more than 4 weeks before the beginning 
of the treatment. 
 
The same method of assessment and the same technique should be used to characterize 
each identified and reported lesion at baseline and during follow-up whenever possible. 
Imaging-based evaluation is preferred to evaluation by clinical examination when both 
methods have been used to assess the anti-tumor effect of a treatment. 
 
Clinical lesions. Clinical lesions will only be considered measurable when they are 
superficial (e.g., skin nodules and palpable lymph nodes). For the case of skin lesions, 
documentation by color photography, including a ruler to estimate the size of the lesion, is 
recommended. 
 
Chest x-ray. Lesions on chest x-ray are acceptable as measurable lesions when they are 
clearly defined and surrounded by aerated lung; however, CT is preferable. 
 
Conventional CT and MRI. These techniques should be performed with cuts of 5 mm or 
less in slice thickness contiguously. Spiral CT should be performed using a 5 mm 
contiguous reconstruction algorithm. This applies to tumors of the chest, abdomen, and 
pelvis.  
 
FDG PET and PET/CT. The acquisition of FDG PET and FDG PET/CT scans should 
follow the NCI Guidelines for using FDG PET as an indicator of therapeutic response 
(L.K. Shankar, J.M. Hoffman, S. Bacharach, M.M. Graham, J. Karp, A.A. Lammertsma, S. 
Larson, D.A. Mankoff, B.A. Siegel, A. Van den Abbeele, J. Yap, D. Sullivan. Consensus 
recommendations for the use of 18F-FDG PET as an indicator of therapeutic response in 
patients in National Cancer Institute Trials. J Nucl Med, 47(6):901-903, 2006). Patients 
should avoid strenuous exercise and be on a low carbohydrate diet for 24 hours prior to the 
scan. Patients should fast for 4 hours or longer prior to the FDG injection and should have 
a serum glucose of less than 200 mg/dL at the time of FDG injection. A 10-20 mCi dose of 
FDG should be injected for typical adult patients. For longitudinal studies with multiple 
scans, particular attention should be paid to ensure consistent patient preparation and 
acquisition parameters between the follow-up scan and the baseline scan. When designing 
a study where PET scans are going to be utilized as one of the modalities to evaluate 
efficacy, it is important to consult with physicians in nuclear medicine in designing the 
appropriate criteria to be utilized. 
 
Tumor markers. Tumor markers alone cannot be used to assess response. If markers are 
initially above the upper normal limit, they must normalize for a subject to be considered 
in complete clinical response. Specific additional criteria for standardized usage of 
prostate-specific antigen (PSA) and CA-125 response in support of clinical trials are being 
developed. 

HCRN GU12-160                                                                                                               Version 7Date 15OCT2014

Cytology, Histology. These techniques can be used to differentiate between partial 
responses (PR) and complete responses (CR) in rare cases (e.g., residual lesions in tumor 
types, such as germ cell tumors, where known residual benign tumors can remain). 
 
The cytological confirmation of the neoplastic origin of any effusion that appears or 
worsens during treatment when the measurable tumor has met criteria for response or 
stable disease is mandatory to differentiate between response or stable disease (an effusion 
may be a side effect of the treatment) and progressive disease. 
 
10.3 Response Criteria  
All participants must have measurable disease defined as at least one target lesion that has not 
been irradiated and can be accurately measured in at least one dimension by RECIST v1.1 
criteria.  
 
10.3.1 
Complete Response (CR) 
Complete disappearance of all measurable and non-measurable disease with no new lesions. Any 
pathological lymph node (target or non-target) must have a reduction in short axis to < 10 mm). 
All markers of disease must have normalized. In some circumstances it may be difficult to 
distinguish residual disease from normal tissue. When determining a CR, it is recommended that 
such lesions be investigated by fine needle aspirate or biopsy whenever possible.  
 
10.3.2 
Partial Response (PR) 
A decrease from baseline of ≥30% of the diameter(s) of all target measurable lesions with no 
unequivocal progression of non-measurable lesions and no new lesions.  
 
10.3.3 
Stable Disease (SD) 
Does not qualify for CR, PR, or progression. 
 
10.3.4 
Progression of Disease (PD) 
One or more of the following 3 criteria must occur for documentation of disease progression: 
1. Appearance of any new lesion or site of disease. (Lesions in areas not previously 
imaged will be considered new).  
2. A 20% increase in the sum of the diameter(s) of target measurable lesions over either 
the smallest sum observed or over baseline if no decrease during therapy has 
occurred. The sum must also demonstrate an absolute increase of at least 5 mm. 
3. Unequivocal progression of non-target lesions alone.  
 
Note: Disease progression based solely on “non-target” lesions alone is exceptional and must be 
made in the context of the entire clinical picture. Worsening (increase in intensity or size of a 
lesion) of pre-existing non-target lesions, including bone lesions, may be difficult to interpret 
and, therefore, will not be considered evidence of progressive disease. In addition, the following 
will not constitute unequivocal progression: 
• Worsening (increased in intensity or size of a lesion) of pre-existing lesions on bone scan 
only, with no new documented lesions. 
• Appearance or worsening of pleural effusions, unless cytologically proven to be 
malignant in origin.

Confidential
 
79 
10.3.5 
Not Evaluable (NE) 
When no imaging/measurement is performed at a particular time point, the patient is not 
evaluable (NE) at that time point. If only a subset of lesion measurements are made at an 
assessment, the case is also considered NE at that time point, unless PD is otherwise determined. 
Prior to any new anticancer therapy, every attempt should be made to perform an imaging 
evaluation.  
 
10.3.6 
Evaluation of Best Overall Response 
The best overall response is the best response recorded from the start of the treatment until 
disease progression/recurrence (taking as reference for progressive disease the smallest 
measurements recorded since the treatment started). The participant's best response assignment 
will depend on the achievement of measurement criteria. Overall response rate will be defined 
as achieving complete or partial response [CR+PR] and disease control rate will be defined as 
achieving stable disease (SD) or better [CR+PR+SD].

reported as "symptomatic deterioration." Every effort should be made to document the 
objective progression even after discontinuation of treatment.

10.3.7 
Duration of Response 
Duration of overall response: The duration of overall response is measured from the time 
measurement criteria are met for CR or PR (whichever is first recorded) until the first date that 
recurrence or PD is objectively documented, taking as reference for PD the smallest 
measurements recorded since the treatment started. 
 
Duration of overall complete response: The duration of overall CR is measured from the time 
measurement criteria are first met for CR until the first date that recurrent disease is 
objectively documented. 
 
Duration of stable disease: Stable disease is measured from randomization until the criteria 
for progression are met, taking as reference the smallest measurements recorded since the 
treatment started. 
 
10.3.8 
Progression-Free Survival 
Progression-Free Survival (PFS) is defined as the duration of time from randomization to time of 
objective disease progression or death from any cause, whichever occurs first. In the absence of 
objective disease progression, PFS will be censored at the date of last disease evaluation without 
progression, unless death occurs within a short period of time (6 weeks, corresponding to the 
interval between disease evaluations) following the date last known progression-free, in which 
case the death will be counted as a PFS event.

11. ADVERSE EVENT REPORTING REQUIREMENTS 
 
11.1 Definitions 
 
11.1.1 
Adverse Event (AE) 
An adverse event (AE) is any unfavorable and unintended sign (including an abnormal 
laboratory finding), symptom or disease temporally associated with the administration, at any 
dose, of a medicinal or therapeutic product whether or not considered related to that product. 
Abnormal laboratory values or diagnostic test results constitute adverse events only if they 
induce clinical signs or symptoms or require treatment or further diagnostic tests.  
 
11.1.2 
Serious adverse event (SAE) 
A serious adverse event (SAE) is any adverse event, occurring at any dose and regardless of 
causality that:  
• Results in death 
• Is life-threatening. Life-threatening means that the person was at immediate risk 
of death from the reaction as it occurred, i.e., it does not include a reaction which 
hypothetically might have caused death had it occurred in a more severe form. 
• Requires or prolongs inpatient hospitalization (i.e., the event required at least a 
24-hour hospitalization or prolonged a hospitalization beyond the expected length 
of stay). Hospitalization admissions and/or surgical operations scheduled to occur 
during the study period, but planned prior to study entry are not considered SAEs 
if the illness or disease existed before the person was enrolled in the trial, 
provided that it did not deteriorate in an unexpected manner during the trial (e.g., 
surgery performed earlier than planned). 
• Results in persistent or significant disability/incapacity. Disability is defined as a 
substantial disruption of a person’s ability to conduct normal life functions. 
• Is a congenital anomaly or birth defect; or 
• Is an important medical event when, based upon appropriate medical judgment, it 
may jeopardize the participant and require medical or surgical intervention to 
prevent one of the outcomes listed above. Examples of such medical 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. 
 
Events not considered to be serious adverse events are hospitalizations for: 
• routine treatment or monitoring of the studied indication, not associated with any 
deterioration in condition, or for elective procedures 
• elective or pre-planned treatment for a pre-existing condition that did not worsen 
• emergency outpatient treatment for an event not fulfilling the serious criteria 
outlined above and not resulting in inpatient admission 
• respite care 
• hospital admission solely for administration of study drug or chemotherapy 
 
11.1.3 
Expectedness 
Adverse events can be 'Expected' or 'Unexpected.'  

HCRN GU12-160                                                                                                               Version 7Date 15OCT2014 
Confidential
 
82 
11.1.3.1 Expected adverse event 
Expected adverse events are those that have been previously identified as resulting from 
administration of the agent. For the purposes of this study, an adverse event is considered 
expected when it appears in the current adverse event list, the Investigator’s Brochure, or is 
included in the informed consent document as a potential risk. 
 
Refer to Section 6.1 for a listing of expected adverse events associated with the study 
agent(s). 
 
11.1.3.2 Unexpected adverse event 
For the purposes of this study, an adverse event is considered unexpected when it varies in 
nature, intensity or frequency from information provided in the current adverse event list, the 
Investigator’s Brochure, the package insert or when it is not included in the informed consent 
document as a potential risk.   
 
11.1.4 
Attribution 
Attribution is the relationship between an adverse event or serious adverse event and the study 
treatment. Attribution will be assigned as follows: 
• Definite – The AE is clearly related to the study treatment. 
• Probable – The AE is likely related to the study treatment. 
• Possible – The AE may be related to the study treatment.  
• Unrelated - The AE is clearly NOT related to the study treatment. 
 
11.2 Procedures for AE and SAE Recording and Reporting 
Participating investigators will assess the occurrence of AEs and SAEs at all participant 
evaluation time points during the study.  
 
All AEs and SAEs whether reported by the participant, discovered during questioning, directly 
observed, or detected by physical examination, laboratory test or other means, will be recorded 
in the participant’s medical record and on the appropriate study-specific eCRF forms.  
 
The descriptions and grading scales found in the revised NCI Common Terminology Criteria for 
Adverse Events (CTCAE) version 4.0 will be utilized for AE reporting. All appropriate treatment 
areas should have access to a copy of the CTCAE version 4.0. 
 
A copy of the CTCAE version 4.0 can be downloaded from the CTEP website at: 
http://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.htm.  
 
11.3 Reporting Requirements 
The study must be conducted in compliance with FDA regulations, local safety reporting 
requirements, and reporting requirements of the principal investigator.  
 
Adverse events (AEs) will be recorded from first dose of study drug and for at least 30 days after 
treatment discontinuation, regardless of whether or not the event(s) are considered related to trial 
medications.  All AEs considered related to trial medication will be followed until resolution, 
return to baseline, or deemed clinically insignificant, even if this occurs post-trial.

Each investigative site will be responsible to report SAEs that occur at that institution to their 
respective IRB. It is the responsibility of each participating investigator to report serious adverse 
events to HCRN and/or others as described below.  
 
11.4 Study Center (Site) Requirements for Reporting SAEs 
Investigators and other site personnel must report any SAEs occurring during the course of the 
study within one business day of discovery of the event.  This includes events both related and 
unrelated to the investigational product.   
 
The completed SAE Report Form (see Study Procedure Manual) must be faxed to HCRN 
within 1 working day of discovery of the event.   The investigator is responsible for informing 
the IRB and/or the Regulatory Authority of the SAE as per local requirements. 
 
The original copy of the SAE Report and the fax confirmation sheet must be kept within the 
Trial Master File at the study site. 
 
Follow-up information will be faxed to HCRN, using a new SAE Report Form stating that this is 
a follow-up to the previously reported SAE and giving the date of the original report. Each re-
occurrence, complication, or progression of the original event should be reported as a follow-up 
to that event regardless of when it occurs. The follow-up information should describe whether 
the event has resolved or continues, if and how it was treated, whether the blind was broken or 
not (if applicable), and whether the participant continued or withdrew from study participation. 
 
11.5 Death and Immediately Life-Threatening Events 
Any death and immediately life-threatening event from any cause while a participant is receiving 
trial treatment on this protocol or up to 30 days after the last dose of trial treatment, or any death 
and immediately life-threatening event occurring more than 30 days after trial treatment has 
ended but which is felt to be treatment related must be reported within one working day of 
discovery of the event.  All deaths must be reported primarily for the purposes of SAE 
reporting; however, deaths due unequivocally to progression are not SAEs.   
 
Your local IRB should be notified and their reporting procedure followed.  The completed SAE 
Reporting Form should be faxed to HCRN within one working day of discovery of the event. 
 
11.6 HCRN Requirements for Reporting SAEs 
HCRN will report any SAE to OncoGenex within one working day of receipt of the SAE 
Reporting Form and to regulatory authorities (FDA) per federal guidelines.   
 
HCRN will fax the SAE form to OncoGenex and will provide follow-up information as 
reasonably requested. 
 
11.7 Reporting to the Institutional Review Board (IRB) 
The Principal Investigator is required to notify his/her Institutional Review Board (IRB) of a 
serious adverse event according to institutional policy.

Each investigative site will be responsible to report SAEs that occur at that institution to 
their respective IRB. 
 
11.8 Reporting to the Food and Drug Administration (FDA) 
HCRN has been designated to manage the Investigator held IND on behalf of  Noah Hahn, MD, 
Sponsor Investigator and will be responsible for all communication with the FDA. HCRN will 
report to the FDA, regardless of the site of occurrence, any adverse event that is serious, 
unexpected and reasonably related (i.e., possible, probable, definite) to the study treatment. 
 
According to CFR 312.32, unexpected fatal or life-threatening experiences associated with the 
use of the study treatment will be reported to FDA by fax or phone as soon as possible but in no 
event later than 7 calendar days after initial receipt of the information. The fax should be sent to 
the FDA project manager assigned to the IND (301) 796-9845. A comprehensive written report 
will be submitted as an amendment to the IND within an additional 8 days (15 calendar days 
total). 
 
All other serious unexpected experiences associated with the use of the study treatment will be 
reported to FDA as an amendment to the IND as soon as possible but in no event later than 15 
calendar days after initial receipt of the information. 
 
Events may be reported to the FDA using Form FDA 3500A or narrative format. Forms are 
available at http://www.fda.gov/medwatch/getforms.htm.  
 
11.9 IND Safety Reports Unrelated to This Trial 
IND safety reports not occurring on this trial but involving OGX-427 (outside SAEs) received 
from outside sources will be forwarded to participating sites for submission to their Institutional 
Review Boards per their guidelines. 
 
11.10  Monitoring of Adverse Events and Period of Observation 
All adverse events, both serious and non-serious, and deaths that are encountered from initiation 
of study intervention, throughout the study, and within 30 days of the last study intervention 
should be followed to their resolution, or until the participating investigator assesses them as 
stable, or the participating investigator determines the event to be irreversible, or the participant 
is lost to follow-up. The presence and resolution of AEs and SAEs (with dates) should be 
documented on the appropriate case report form and recorded in the participant’s medical record 
to facilitate source data verification.  
 
For some SAEs, the sponsor-investigator or designee may follow-up by telephone, fax, and/or 
monitoring visit to obtain additional case details deemed necessary to appropriately evaluate the 
SAE report (e.g., hospital discharge summary, consultant report, or autopsy report).  
 
Participating investigators should report any serious post-study event(s) that might reasonably be 
related to participation in this study. Participating investigators should notify HCRN and their 
respective IRB of any unanticipated death or adverse event occurring after a participant has 
discontinued or terminated study participation that may reasonably be related to the study.

12. DATA AND SAFETY MONITORING 
 
12.1 Data Reporting 
 
12.1.1 
Independent Data Safety Monitor (DSM)  
Safety monitoring will be performed by an independent data safety monitor (DSM) who will 
be appointed for this study.  
 
Although OGX-427 was tolerable at 1000 mg doses in combination with docetaxel and an 
MTD was not reached in the Phase 1 study, there will be a scheduled DSM safety review 
after the first 20 participants have been enrolled (approximately 10 per treatment arm) and 
treated for at least one cycle as a precaution to assess the frequency of  Grade 3 adverse 
events and serious adverse events in this participant population. Further safety reviews will 
be conducted according to the schedule outlined in Section 12.3.  
 
The DSM will be an oncologist experienced in the treatment of cancer patients with 
chemotherapy regimens. The primary responsibility of the DSM will be overall safety for 
participants on the protocol. The DSM will monitor the safety of individual participants 
during the entire adverse event reporting period (i.e., from the first administration of Study 
Drug through 30 days after completion of the final cycle of chemotherapy treatment or 
maintenance, whichever comes last). The DSM will:  
a. Review all SAEs reported to the HCRN. The HCRN will provide the DSM with 
a copy of any unexpected Study Drug-related SAE Report Form within 15 
business days of receipt by the HCRN. The Medical Monitor will also provide 
the DSM with copies of all expedited SAE reports submitted to regulatory 
agencies.  
b. Perform periodic reviews of all safety data for individual participants. This will 
be accomplished by review of individual participant data listings provided by an 
independent, unblinded statistician. These listings will be based on the available 
safety data in the clinical study database and will include: demographic 
characteristics, general medical history (including concurrent illnesses), disease 
history, prior cancer therapies, Study Drug administration, vital signs during 
infusion, clinical laboratory data (serum chemistry, hematology, coagulation, 
urine dipstick), reported adverse events and concomitant medications. 
c. Perform continued monitoring of Grade 3 and higher adverse events and SAEs 
on an ongoing basis for all participants. 
 
12.2 Study Monitoring 
Monitoring visits to the trial sites will be made periodically during the trial, to ensure all aspects 
of the protocol are followed.  Source documents will be reviewed for verification of agreement 
with data as submitted via the data collection system.  The investigator/institution guarantee 
access to source documents by HCRN or its designee and appropriate regulatory agencies. 
The trial site may also be subject to quality assurance audit by OncoGenex or its designee as well 
as inspection by appropriate regulatory agencies. 
It is important for the investigator and their relevant personnel to be available during the 
monitoring visits and possible audits and for sufficient time to be devoted to the process.

12.3 Data and Safety Monitoring Board 
The Dana-Farber/Harvard Cancer Center (DF/HCC) Data and Safety Monitoring Board (DSMB) 
will review and monitor study progress, toxicity, safety and other data from this trial. The board 
is chaired by a medical oncologist from outside of DF/HCC (See Section 12.1.1 regarding the 
DSM) and has external and internal representation. Information that raises any questions about 
participant safety or protocol performance will be addressed with the Sponsor Investigator, Co-
PIs, statistician, and study team members.  Should any major concerns arise, the DSMB will 
offer recommendations regarding whether or not to suspend the trial. 
The DSMB will meet twice a year to review accrual, toxicity, response and reporting 
information. Information to be provided by HCRN and study Statistician to the DSMB may 
include: participant accrual, treatment regimen information, adverse events and serious adverse 
events reported by category, summary of any deaths on study, audit results, and a summary 
provided by the study team. Other information (e.g. scans, laboratory values) will be provided 
upon request. 
 
12.4 Data/Safety Monitoring and Reporting Guidelines 
HCRN will compile data summary reports for this trial and submit these reports monthly to the 
Sponsor Investigator.  HCRN will submit data summary reports twice-yearly to the DF/HCC 
Data and Safety Monitoring Board (DSMB) for review.  
 
13. DATA HANDLING AND RECORD KEEPING 
 
13.1 Case Report Forms 
An electronic case report form (eCRF) is required and must be completed for each included 
participant.  The trial statistical analysis will be coordinated and performed by the study 
Statistician at Dana-Farber Cancer Institute. The completed dataset is the property of the Sponsor 
Investigator and/or Institution and should not be made available in any form to third parties, 
except for authorized representatives of appropriate Health/Regulatory Authorities, without 
written permission of the Sponsor Investigator and/or Institution.  The Sponsor Investigator, 
Institution, and Hoosier Cancer Research Network shall each grant OncoGenex and its 
representatives reasonable access to study data and HCRN, at OncoGenex’s expense, shall 
provide to OncoGenex and its representatives SAS data sets containing all observations, results 
and conclusions related to or resulting from the study at the completion of the study.  
 
Sponsor Investigator and Institution grant to OncoGenex a license, with the right to grant 
sublicenses, to use the study data for its business purposes and to study sites for their own 
internal research and educational purposes. 
 
13.2 Record Retention 
To enable evaluations and/or audits from Health Authorities, HCRN, or the Sponsor Investigator, 
the Participating Investigator agrees to keep records, including the identity of all participating 
participants (sufficient information to link records; e.g., hospital records), all original signed 
informed consent forms, copies of all source documents, and detailed records of drug disposition.  
To comply with international regulations, the records should be retained by the investigator in 
compliance with regulations.

During data entry, range and missing data checks will be performed on-line.  The checks to be 
performed will be documented in the Data Monitoring Plan for the study.  A summary report 
(QC Report) of these checks together with any queries resulting from manual review of the 
eCRF’s will be generated for each site and transmitted to the site and the site monitor.  
Corrections will be made by the study site personnel.  This will be done on an ongoing basis. 
 
14. REGULATORY CONSIDERATIONS 
 
14.1 Protocol Review and Amendments 
This protocol, the proposed informed consent and all forms of participant information related 
to the study (e.g., advertisements used to recruit participants) and any other necessary 
documents must be submitted, reviewed and approved by a properly constituted IRB 
governing each study location.  
 
Study procedures will not be changed without the mutual agreement of the Sponsor 
Investigator, HCRN, and OncoGenex. 
 
If it is necessary for the study protocol to be amended, the amendment or a new version of the 
study protocol (amended protocol) will be generated by HCRN and must be approved by each 
IRB, OncoGenex, and if applicable, also the local regulatory authority.  Local requirements 
must be followed. Protocol amendments must also be submitted to the FDA. 
 
If a protocol amendment requires a change to the Written Informed Consent Form, then each 
IRB must be notified.  Approval of the revised Written Informed Consent Form by the IRB is 
required before the revised form is used.  
 
The Participating Investigator is responsible for the distribution of these documents to his or her 
IRB, and to the staff at his or her center.  The distribution of these documents to the regulatory 
authority will be handled according to local practice. 
 
All decisions of the IRB concerning the conduct of the study must be made in writing. 
OncoGenex’s willingness to supply OGX-427 is predicated upon the review of the protocol.  
HCRN agrees to provide written notice to OncoGenex of any modifications to the protocol or 
informed consent. 
 
14.2 Informed Consent 
All participants must be provided a consent form describing this study and providing 
sufficient information for participants to make an informed decision about their participation 
in this study. The formal consent of a participant, using the IRB approved consent form, must 
be obtained before the participant is involved in any study-related procedure. The consent 
form must be signed and dated by the participant or the participant’s legally authorized 
representative, and by the person obtaining the consent. The participant must be given a copy 
of the signed and dated consent document. The original signed copy of the consent document 
must be retained in the medical record or research file.

15. STATISTICAL CONSIDERATIONS 
 
Statistical analysis for this study will be the responsibility of the Dana-Farber Cancer Institute 
(DFCI) Dept. of Biostatistics and Computational Biology. 
 
15.1 Study Design/Primary Objectives 
This is a randomized, open-label trial to evaluate whether suppression of Hsp27 production using 
OGX-427, a second-generation antisense oligonucleotide (ASO), in combination with docetaxel 
can prolong OS time compared to docetaxel alone in participants with metastatic or inoperable, 
locally-advanced urothelial carcinoma (UC) that are relapsed after, or refractory to a platinum-
containing regimen. Participants will be randomized with 1:1 allocation to receive docetaxel +/- 
OGX-427 using permuted blocks methods within strata.39  Overall survival is defined in 
Section 10.4.  
 
Based on the docetaxel plus vandetanib vs. docetaxel trial33 in a similar patient population, the 
median OS on the docetaxel control arm is expected to be 6 months (hazard rate of 0.1155). This 
study is designed to have adequate power to detect a 33% reduction in the OS hazard rate (to 
0.0770) on the docetaxel + OGX-427 arm corresponding to a hazard ratio (docetaxel + OGX-
427/ docetaxel) = 0.667. If OS follows an exponential distribution, then this difference 
corresponds approximately to a 50% improvement in median OS (to 9 months on the docetaxel + 
OGX-427 arm). The null hypothesis is no difference in treatment effect. The primary analysis is 
a superiority test of OS, performed at one-sided 0.10 significance level using a stratified logrank 
test.40 There will be 90% power to detect this OS difference assuming 200 participants are 
enrolled over 31 months with 8 months of additional follow-up (39 months/3.25 years total 
duration).  Full information under the alternative hypothesis will occur at 162 deaths.  
 
The Kaplan-Meier (KM) method will be used to estimate OS distributions by treatment arm.41 A 
stratified Cox proportional hazards (PH) regression model will estimate the OS treatment hazard 
ratio and 80% 2-sided confidence intervals in unadjusted and adjusted models.42 Exploratory 
subgroup analyses will investigate heterogeneity of treatment effects according to subgroups 
defined by the stratification factors, estimating hazard ratios within subgroups and testing for 
treatment-by-subgroup interaction in Cox PH regression models.  

HCRN GU12-160                                                                                                               Version 7Date 15OCT2014

90 
The study will also be monitored for futility with one interim analysis, planned prior to 
completion of accrual at approximately 50% information (approximately 81 deaths).  Routine 
study procedures will continue during the interim analysis. The decision for early rejection of the 
experimental therapy will be guided by a hazard ratio boundary using the spending function 
methodology of Lan and DeMets with O’Brien-Fleming parameter to adjust the boundary for the 
actual interim analysis time. If conducted precisely at 50% information, the cut-off hazard ratio 
is 1.052 corresponding to a z-scale value of -0.227. If the hazard ratio estimate lies above 1.052, 
the study may be stopped early. Under the null hypothesis, the boundary crossing probability is 
0.41. The futility rule with a beta spent of 0.020 at the one interim analysis is incorporated in the 
power calculation for efficacy and has negligible impact on sample size.  
 
Sample size and interim monitoring considerations used East version 5.2 (Cytel Inc.). 
 
15.2 Sample Size/Accrual Rate 
To enroll 200 participants, accrual duration is expected to be 31 months (2.6 years) with a 
segmented accrual rate target to account for slower accrual while institutions activate the trial: 4 
participants per month in the first 6 months and 7 participants per month for the remainder of the 
accrual period. Thus in years 1, 2 and 3 the accrual goals are 66, 84 and 50 participants, 
respectively. Accrual expectations use as reference the multi-institution (n=17 institutions) 
vandetanib docetaxel trial, which achieved an overall accrual rate of 4 participants per month, 
but the accrual rate in the last year was 7 participants per month.  
 
15.3 Stratification Factors 
As specified in Section 5.6, randomization will be stratified in order to minimize between-arm 
imbalance using two stratification factors: time from prior systemic chemotherapy (<3 versus 3 
months); and number of Bellmunt37 prognostic factors prior to randomization (0 versus 1-3 
factors).  
 
Evaluation of primary and secondary endpoints incorporates methods for stratified analyses.  
 
15.4 Analysis of Secondary Objectives 
Safety and tolerability of OGX-427 in combination with docetaxel will be compared to that of 
docetaxel alone. Each reported adverse event will be summarized as the highest grade 
experienced. Adverse events will be summarized according to grade, overall and by treatment 
arm, as number and percentage of participants. Specific adverse events (to be pre-specified in the 
Statistical Analysis Plan) will be compared between groups using Fisher’s exact tests. 
 
Overall response rate and disease control rate (defined in Section 10.3.6) will be summarized as 
number and percentage of participants by treatment arm with two-sided 80% CI and compared 
using Fisher’s exact tests. With 100 participants per treatment arm and assuming 10% overall 
response rate in the docetaxel control arm, there is 80% power to detect an improvement to 22% 
in the experimental docetaxel + OGX-427 arm (Fisher’s exact test, one-sided =0.10). 
 
The distributions of duration of response (Section 10.3.7) and PFS (Section 10.3.8) will be 
estimated using KM method by treatment arm, with median and two-sided 80% CI of the 
distribution summarized. PFS will be compared between treatment arms using a stratified 

HCRN GU12-160                                                                                                               Version 7Date 15OCT2014 
Confidential
 
91 
logrank test. With 100 participants per group and assuming 1.5 month (6 week) median PFS in 
the docetaxel control arm, there is over 90% power to detect an improvement to 3 month (12 
week) median PFS in the experimental docetaxel + OGX-427 arm (logrank test, one-sided =0. 
10; 71 required PFS events). 
 
Serum levels of Hsp27 (or other proteins) will be summarized descriptively over time as median 
and inter-quartile ranges at baseline and each treatment cycle, separately by treatment arm. The 
percentage changes in serum levels from baseline over time will also be summarized, as well as 
the maximum percentage of serum level decline from baseline over 2 cycles and over all cycles 
of treatment.  
 
Serum Hsp27 levels at baseline will be explored as a possible prognostic or predictive marker. It 
is hypothesized that participants with higher baseline Hsp27 level will have better OS when 
treated with docetaxel+OGX-427 vs. docetaxel alone relative to participants with lower Hsp27 
levels. Since no clinically meaningful cutoff point has been previously established, serum Hsp27 
(or other protein) levels will be categorized at quartiles or median for assessing the associations 
with OS. The distribution of OS according to Hsp27 level will be estimated using KM method, 
overall and by treatment arm.  A stratified Cox PH regression model will be used to assess the 
association of Hsp27 with OS, to estimate treatment hazard ratios by Hsp27 subgroup, and to test 
the treatment-by-Hsp27 interaction. To investigate the association of percentage changes in 
serum Hsp27 level with OS, a landmark analysis approach (with a landmark set after cycle 2, 
i.e., 6 weeks, when the first imaging takes place) will be used. The serum Hsp27 measurements 
during the first 2 cycles on study therapy will be used to calculate the maximum percentage of 
decline from baseline.  Among participants who are alive after cycle 2, the association of 
maximum decline in serum Hsp27 levels with OS (re-defined from the landmark point) will be 
investigated as described above. 
 
CTC enumeration and expression of Hsp27 and other relevant proteins will be measured by 
immunoflourescence and levels of telomerase will be analyzed by quantitative PCR at Screening, 
day 1 cycle 2, day 1 cycle 3 and day 1 cycle 5.  The associations of CTC number, telomerase 
activity and CTC expression of Hsp27 at Screening with OS will be evaluated, similarly as 
described above for serum Hsp27 levels.  The changes of CTC number, telomerase activity and 
expression of Hsp27 from Screening to day 1 cycle 2 will be summarized descriptively, and their 
association with OS will be evaluated using a landmark analysis.  CTC measurements and 
telomerase activity also will be summarized according to patient disease status at time of day 1 
cycle 3 and day 1 cycle 5 when radiographic evaluation are done.  
 
Hsp27 protein is highly expressed in bladder tumor tissue, with one cohort20 of 42 samples 
reporting 9.5%, 7%, 28.5%, 55% of samples having 0, 1-50%, 51-80% and >80% Hsp27 
immunostaining, respectively. Tumor expression of Hsp27 will be summarized descriptively as 
median and inter-quartile ranges. Since no clinically meaningful cutoff point has been previously 
established, Hsp27 expression will be categorized at quartiles or median, and the association 
with OS investigated as described above for serum levels. 
 
In consideration of power for correlative studies, we assume 80% of participants have samples 
assayed (160 participants; 130 deaths). Assuming Hsp27 is dichotomized at the median, there is 

HCRN GU12-160                                                                                                               Version 7Date 15OCT2014

92 
80% power to detect a hazard ratio of 0.69 (one-sided =0.10). To test treatment-by-Hsp27 
interaction, assuming the overall treatment hazard ratio is 0.67 and the Hsp27 hazard ratio is 
0.69, then there is 75% power to detect an interaction ratio of 0.5 (e.g., high Hsp27 treatment 
HR=0.44 vs. low Hsp27 HR=0.88) (one-sided =0.10).  
 
15.5 Reporting and Exclusions

to randomized treatment assignment, based on the intention-to-treat (ITT) principle. 
 
16. PUBLICATION PLAN 
 
HCRN assures that the key design elements of this protocol will be posted in a publicly 
accessible database such as clinicaltrials.gov prior to participant enrollment. In addition, upon 
study completion and finalization of the study report the results of this study will be either 
submitted for publication and/or posted in a publicly accessible database of clinical study results.  
 
The first publication relating to the study will reflect the overall results of the study at all sites. 
The first publication will be the responsibility of the Sponsor Investigator, Co-PIs and study 
Statistician. In the event there is no multi-center publication within 12 months after the study 
data lock, or unless otherwise notified earlier by OncoGenex, Sponsor Investigator and the study 
sites shall have the right to publish the results from the study.
