PROTOCOL SYNOPSIS
Study Objectives Phase II Study
Primary 

Determine whether the timing of ipilimumab administration impacts PAP and PA2024-
specific immune responses induced by SipT.
Secondary

Assess the safety associated with giving ipilimumab either immediately following completion 
of Sipuleucel-T (SipT) or delayed ipilimumab following SipT.

Assess clinical activity of the combination therapy for each study arm in chemotherapy-naïve 
patients with metastatic CRPC.

Determine whether the timing of ipilimumab administration impacts the immunomodulation 
of activated effector and regulatory T cells.
Study Design
This is a non-comparative open-label randomized multicenter Phase 2 clinical trial combining SipT 
with ipilimumab in patients with chemotherapy-naïve metastatic CRPC. 
All patients will be treated with the fixed treatment backbone of SipT (Q2 wks x 3).  Patients will be 
randomized to one of two arms:
Arm 1 (Immediate Treatment): 
Ipilimumab Q3 wks x 4 started 1 day following the final dose of SipT (Day 0).
Arm 2 (Delayed Treatment): 
Ipilimumab Q3 wks x 4 started 3 weeks following the final dose of SipT (Day 0).
Following this ipilimumab treatment, patients will then be followed monthly for 3 months and then 
quarterly until disease progression. The definition of unacceptable toxicity is grade 3 or higher 
treatment-related toxicities (NCI CTCAE v4) excluding irAEs. The study will assess for the 
immunogenicity and clinical activity of sequential sipuleucel-T treatment followed by ipilimumab. 
Patients who experience an initial clinical response to ipilimumab followed by subsequent disease 
progression will be offered reinduction treatment with ipilimumab.
Sample Size and Population:
Twenty-seven patients will be required in each of the two treatment arms, and up to 54 prostate 
cancer patients will be required to complete this multicenter study, which includes the initial safety 
cohort.  Men with chemotherapy-naïve metastatic castrate resistant prostate cancer (CRPC) will be 
candidates for this clinical trial.  Other key inclusion criteria include the following:

Progressive disease after androgen deprivation, as defined by PSA Working Group 2 
and/or immune-related response criteria (irRC) 

Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1

Page 3 of 84

No prior chemotherapy for prostate cancer, with the exception of neoadjuvant 
chemotherapy 

No prior sipuleucel-T treatment or investigational immunotherapy

No prostate cancer pain requiring regularly scheduled narcotics.

No concurrent treatment with systemic steroid therapy
Treatment:
Sipuleucel-T (Provenge) is an FDA-approved autologous cellular immunotherapy designed to 
stimulate an immune response against prostate cancer. It consists of autologous peripheral blood 
mononuclear cells (PBMCs), including antigen presenting cells (APCs), which have been activated 
in vitro with a recombinant fusion protein comprised of prostatic acid phosphatase (PAP) and GM-
CSF. Patients will be treated with standard commercial sipuleucel-T (SipT) treatment of 3 planned 
doses given intravenously (IV) every 2 weeks.
Ipilimumab (Yervoy) is a human anti-CTLA4 monoclonal antibody designed to stimulate immune 
responses to cancer. It is FDA-approved in the treatment of metastatic melanoma.  Patients will 
receive 4 planned doses of ipilimumab given IV every 3 weeks.  Ipilimumab will be given following 
completion of SipT treatment.  Study subjects will be randomized 1:1 to start ipilimumab either 1 day 
following completion of SipT or 3 weeks following completion of SipT.
Endpoints
Primary

To assess the impact of the timing of ipilimumab treatment on the induction of IgG 
antibodies by SipT, the proportion of patients on each study arm who achieve an immune 
response to PAP and/or PA2024 at study week 20 will be determined.  A positive immune 
response is defined as a titer > 1:400. 
Secondary

To assess the safety of immediate sequential vs. delayed sequential ipilimumab following 
SipT the maximum grade of each toxicity and adverse event according to the NCI CTCAE v4 
as well as immune related adverse events (see section 5.4.5) will be tabulated for each study 
arm.

Clinical activity will be assessed separately for each study arm by: 
-
the proportion of patients achieving a PSA decline of at least 30% and at least 50% below 
baseline using PSAWG2 criteria 
-
the proportion of patients achieving a radiographic clinical response according to the 
immune-related response criteria
-
median time to progression with the duration of time to progression for each patient 
measured from the start of protocol therapy until progression after 4 cycles of protocol 
therapy

Modulation of Effector and Regulatory T Cells:
-
Measures of T cell immune activation will be compared between the two study arms.  
Summary descriptive statistics including means, mean change from baseline and 
proportions will be presented for each study arm. Measurements of a T cell response to 
PAP and PA2024 using IFNg ELISPOT will be obtained over time. A positive response

is defined at >10 spots/300,000 and will be assessed through week 32. The change from 
baseline in activated CD4 and CD8 T cells as well as for FoxP3+ CD4+ regulatory T 
cells will be evaluated through week 20.

INTRODUCTION
This is a non-comparative open-label randomized phase 2 study to treat patients with 
chemotherapy-naïve, metastatic CRPC with standard sipuleucel-T (SipT) of 3 treatments Q2 
wks.  Subjects will then initiate ipilimumab treatment (Q3 wks x 4 doses) either 1 day following 
the last dose of SipT (immediate arm) or 3 wks following the last dose of SipT (delayed arm) 
until disease progression or toxicity. Subjects will receive ipilimumab at the 3 mg/kg dose. 
Twenty-seven evaluable patients will be required per treatment arm, and a total of 54-86 prostate 
cancer patients will be required to complete this multicenter study. The study will assess 
immunologic activity of immediate ipilimumab administration following SipT treatment and 
delayed ipilimumab administration following SipT as measured by immune responses to 
prostatic acid phosphatase (PAP) and the PAP- GM-CSF fusion protein (PA2024). The latter is 
the antigen used in producing SipT.
1.1
Research Hypothesis
We hypothesize that combining Sipuleucel T with ipilimumab will enhance the immunogenicity 
and clinical efficacy as determined by PSA decline and time to progression of this treatment.  
We also hypothesize that potentiation of PAP-specific T cell responses will be dependent on 
timing of anti-CTLA-4 administration in relationship to last dose of sipuleucel-T (SipT).
1.2
Background
1.2.1
Sipuleucel –T
1.2.1.1
Pre-Clinical Studies
Pre-clinical studies demonstrated that prostatic acid phosphatase (PAP) can be immunogenic in 
rats 1. Antigen presenting cells (APCs) loaded with a fusion protein consisting of rat prostatic 
acid phosphatase (PAP) coupled to a targeting molecule, rat granulocyte-macrophage colony 
stimulating factor (GM-CSF), induced strong cellular immune responses in vivo to tissues and 
tumors that express PAP 2.  Based on these observations, an APC product, designated sipuleucel-
T, was developed for the treatment of men with prostate cancer.
1.2.1.2
Clinical Experience of Sipuleucel-T
Sipuleucel-T is an autologous cellular product that is enriched for antigen presenting cells and 
cocultured ex vivo with a fusion protein comprised of prostatic acid phosphatase (PAP) and GM-
CSF (PA2024).  While the precise mechanism of how SipT works is not fully elucidated, it is 
thought to serve as a cellular vaccine against PAP.  We initially demonstrated that prostatic acid 
phosphatase can be immunogenic in rodent models 1.  UCSF has since led phase I, II, and III 
clinical trials with SipT demonstrating that SipT can induce immune responses and some clinical 
activity 3,4. Two randomized, double-blind, placebo-controlled clinical trials have now since 
demonstrated that SipT enhances overall survival in metastatic, asymptomatic CRPC patients 
treated with upfront SipT (pre-chemotherapy) 4,5. In the first randomized, double blind, placebo-
controlled, Phase 3 trial (D9901, n = 127 subjects), subjects randomized to sipuleucel-T had a

Phase II – ipilimumab/sipuleucel-T
Page 11 of 84
41% reduction in the risk of death relative to those randomized to placebo (hazard ratio (HR) = 
1.71 [95% confidence interval (CI): 1.13, 2.58] P = 0.010, 2-sided log rank).  The median 
survival was 25.9 months for subjects randomized to sipuleucel-T compared to 21.4 months for 
those randomized to placebo.  At 36 months from randomization with complete follow-up, the 
survival rate for subjects receiving sipuleucel-T was 34% compared to 11% for subjects 
receiving placebo (P = 0.0046, chi square).  In addition, subjects randomized to sipuleucel-T had 
a 31% reduction in time to disease progression (P = 0.052, log rank).  The second randomized, 
double blind, placebo-controlled (IMPACT, n=512 patients) demonstrated a relative reduction of 
22% in the risk of death as compared with the placebo group (hazard ratio, 0.78; 95% confidence 
interval [CI], 0.61 to 0.98; P=0.03) 6. This reduction represented a 4.1-month improvement in 
median survival (25.8 months in the sipuleucel-T group vs. 21.7 months in the placebo group). 
The 36-month survival probability was 31.7% in the sipuleucel-T group versus 23.0% in the 
placebo group. Despite an overall survival advantage, there was no difference in time to 
progression (TTP) between the placebo and treatment arms. In patients with advanced disease, 
generation of an immune response to the vaccine is related to an improved clinical outcome 
4(Dendreon, personal communication).  Thus increasing the frequency and/or potency of immune 
responses induced by SipT plus anti-CTLA4 may therefore enhance the clinical efficacy of this 
treatment.
The overall adverse event (AE) profile observed in the completed Phase 3 studies was similar to 
the Phase 2 profile.  The following infusion-related AEs occurred more frequently (P  0.05) in 
subjects treated with sipuleucel-T than those treated with placebo: chills, pyrexia, headache, 
tremor, asthenia, and vomiting.  These events were generally mild or moderate in severity and 
resolved within 1 to 2 days. 
A possible increased risk of cerebrovascular events has been observed.  For all randomized 
studies conducted to date, the incidence of cerebrovascular events of any etiology was 3.9% in 
subjects treated with sipuleucel-T (18 of 461 subjects) compared with 2.6% in subjects treated 
with placebo (6 of 231 subjects).  The odds ratio (OR) for risk of stroke in the sipuleucel-T arm 
relative to the control arm is 1.52, with the 95% CI overlapping 1.00 (95% CI: 0.60, 3.89]; 
P = 0.510).  The incidence of hemorrhagic events was 0.7% in subjects treated with sipuleucel-T 
compared to 0.4% in subjects treated with placebo; the incidence of ischemic events was 2.4% 
compared to 2.2%, respectively; and 4 cerebrovascular events in subjects treated with 
sipuleucel-T were of unknown etiology (0.9%).  The majority of cerebrovascular events were not 
fatal, with 1.5% and 0.9% of the events resulting in death for subjects treated with sipuleucel-T 
and placebo, respectively (OR = 1.76 [95% CI: 0.36, 8.57]; P = 0.725).  Conclusions regarding 
the increased risk of cerebrovascular events cannot be drawn at this time given the small number 
of events and large confidence intervals.  Additional studies are underway to better characterize 
these events.
1.2.2
Ipilimumab
1.2.2.1
Pharmacology of Ipilimumab
Ipilimumab is a human immunoglobulin G (IgG1)κ anti-CTLA-4 monoclonal antibody (mAb). 
In vitro studies were performed with ipilimumab to demonstrate that it is specific for CTLA-4, 
actively inhibits CTLA-4 interactions with B7.1 and B7.2, does not show any cross-reactivity 
with human B7.1, B7.2 negative cell lines, and stains the appropriate cells without non-specific

Phase II – ipilimumab/sipuleucel-T
Page 12 of 84
cross-reactivity in normal human tissues, as demonstrated by immunohistochemistry. 
Ipilimumab does cross-react with CTLA-4 in non-human primates including cynomolgus 
monkeys.
Ipilimumab was originally produced and purified from a hybridoma clone. Subsequently, a 
transfectoma (CHO cell) has been generated that is capable of producing more ipilimumab on a 
per cell basis than the hybridoma. Material from the transfectoma will be utilized in this and 
future ipilimumab clinical studies. Biochemical, immunologic and in vivo preclinical primate 
assessments demonstrated similarity between hybridoma and transfectoma-derived ipilimumab.
1.2.2.2
Pre-Clinical Toxicology of Ipilimumab
Complete information on the pre-clinical toxicology studies can be found in the Ipilimumab 
Investigator Brochure (IB). Non-clinical toxicity assessments included in vitro evaluation for the 
potential of ipilimumab to mediate complement-dependent cellular cytotoxicity (CDCC) or 
antibody-dependent cellular cytotoxicity (ADCC), and toxicology assessments in cynomolgus 
monkeys alone and in the presence of vaccines.
The in vitro studies demonstrated that ipilimumab did not mediate CDCC of PHA- or CD3-
activated human T cells. However, low to moderate ADCC activity was noted at concentrations 
up to 50 ug/mL. These data are consistent with the requirement of high levels of antigen 
expression on the surface of target cells for efficient ADCC or CDCC. Since ipilimumab is a 
human IgG1, an isotype generally capable of mediating CDCC and ADCC, the lack of these 
activities is likely due to a very low expression of CTLA-4 on activated T cells. Therefore, these 
data suggest that ipilimumab treatment would not result in depletion of activated T cells in- vivo. 
Indeed, no depletion of T cells or T cell subsets were noted in toxicology studies in cynomolgus 
monkeys.
No mortality or signs of toxicity were observed in three independent 14-day intravenous 
toxicology studies in cynomolgus monkeys at multiple doses up to 30 mg/kg/dose. Furthermore, 
ipilimumab was evaluated in sub chronic and chronic toxicology studies in cynomolgus monkeys 
with and without Hepatitis B (HepB) Vaccine and Melanoma Vaccine. Ipilimumab was well 
tolerated alone or in combination in all studies. There were no significant changes in clinical 
signs, body weight values, clinical pathology values or T cell activation markers. In addition, 
there were no significant histopathology changes in the stomach or colon.
1.2.2.3
Human Pharmacokinetics of Ipilimumab
Pharmacokinetic (PK) profiles for ipilimumab have been analyzed. The primary objective of 
Protocol MDX010-015 was to determine the safety and PK profile of single and multiple doses 
of ipilimumab derived from a transfectoma or hybridoma cell line. Mean plasma concentrations 
of ipilimumab administered at doses of 3 mg/kg (hybridoma-derived drug product); 2.8 mg/kg, 
5 mg/kg, 7.5 mg/kg, 10 mg/kg, 15 mg/kg, and 20 mg/kg (transfectoma-derived drug product) 
demonstrated approximate dose proportionality. Equimolar doses of hybridoma-derived and 
transfectoma-derived drug product had comparable PK profiles. The range of mean volume of 
distribution at steady state (Vss) across cohorts 2.8, 3, 5, 7.5, 10, 15, and 20 mg/kg, was 57.3 to 
82.6 mL/kg, indicating drug distribution was mostly limited to the intravascular space. The 
clearance was low (range 0.11 to 0.29 mL/h/kg) and reflective of the half-life (range 297 to 
414 h), which is consistent with the long terminal disposition phase of ipilimumab. There was

moderate variability in the PK parameters among subjects, with CV of 11% to 48% in AUC (0-
21d), 20% to 59% in CL, and 17% to 46% in Vss.

Clinical Experience with Ipilimumab
Ipilimumab is has been shown to improve overall survival in patients with advanced melanoma 
(unresectable Stage III or Stage IV) 7,8.  These results prompted FDA-approval of ipilimumab for 
the treatment of advanced melanoma in 2011.
Ipilimumab has been administered to approximately 2901 patients with different cancers in 25 
completed or ongoing clinical trials as of 31-Mar-2009 with a dose range between 0.3 mg/kg and 
20 mg/kg and in various combinations.
In general, the safety profile of ipilimumab administered as single doses of up to 20-mg/kg and 
multiple doses of up to 10 mg/kg every 3 weeks was characterized by adverse reactions that were 
mostly immune in nature. Drug-related SAEs were reported in studies of ipilimumab 
administered as monotherapy, as well as in combination with vaccines, cytokines, chemotherapy, 
or radiation therapy.
The overall summary of safety for the 2901 patients treated with ipilimumab in the completed or 
ongoing clinical trials and the subset of 658 patients treated at the 10 mg/kg dose level is 
presented in Table 1.

Among all treated subjects, the most frequently reported treatment-related AEs of any grade 
included fatigue (27.8%), diarrhea (27.5%), nausea (23.4%), rash (21.8%), pruritus (19.9%), 
pyrexia (11.9%), and vomiting (11.7%). 
Similarly, among subjects treated with ipilimumab at 10 mg/kg, the most frequently reported 
treatment-related AEs of any grade included diarrhea (38.1%), fatigue (30.5%), rash (34.5%), 
pruritus (29.8%), nausea (17.6%), pyrexia (12.3%), vomiting (10.9%) and colitis (10.2%).
1.2.2.6
Immune-Related Adverse Events (irAEs) with Ipilimumab
Many of the adverse events considered related to ipilimumab may be immune in nature and 
presumably a consequence of the intrinsic biological activity of ipilimumab. An irAE is defined 
as any adverse event associated with drug exposure and consistent with an immune-mediated 
event. Disease progression, infections and other etiologic causes are ruled out or deemed 
unlikely as contributing to the event. Supportive data, such as autoimmune serology tests or 
biopsies, are helpful but not necessary to deem an event an irAE. Events of unclear etiology, 
which were plausibly “immune-mediated” have been conservatively categorized as irAEs even if 
serologic or histopathology data are absent. These irAEs likely reflect a loss of tolerance to some 
self-antigens or an unchecked immune response to gut or skin flora. Some breakthrough of 
immunity may be inseparably linked to the clinical antitumor activity of ipilimumab.
Immune-related AEs predominately involve the GI tract, endocrine glands, liver or skin.
Among all 2901 treated subjects, 59.6% (1729/2901) of subjects reported any irAE and 15.2% 
(441/2901) of subjects reported serious irAEs. Among subjects who received ipilimumab at 10 
mg/kg, 21.9% (144/658) of subjects reported serious irAEs. 
Table 2 summarizes the incidence of serious irAEs among all treated subjects and subjects who 
received ipilimumab 10 mg/kg.

aBased on treatment-related adverse events retrieved from the clinical database using pre-defined MedDRA terms that were considered 
potential irAEs.
With few exceptions, irAEs were clinically manageable and reversible with supportive care or 
corticosteroids. Management algorithms are included in the IB. 
Corticosteroid treatment did not adversely affect antitumor responses in those subjects who had 
both an irAE requiring steroid therapy and an objective tumor response. Systemic corticosteroids 
do not appear adversely associated with ipilimumab-induced clinical response when used to 
manage irAEs in patients with advanced melanoma. Similar results were observed regardless of 
whether mWHO or the novel immune-related response criteria (irRC) 9 were used. Steroids can 
be used promptly to manage severe irAEs and minimize the risk for serious complications10. 
In the setting where subjects were enrolled to receive ipilimumab every 3 weeks dosing until 
progression, irAEs could be reported at any time, with colitis and rash reported most often during 
the early doses and hypophysitis reported with later doses.
Gastrointestinal irAEs
The most common Grade 3 or greater irAE involved the lower GI tract and clinically manifested 
as diarrhea or hematochezia. Diarrhea resulting from treatment with ipilimumab ranged from 
mild to severe and was life-threatening in some cases. Some cases of diarrhea began as mild and 
became very severe. Among subjects who received ipilimumab at 10 mg/kg, GI irAEs of any 
grade were reported for 40.0% (263/658) of subjects, and Grade 3 – 4 GI irAEs were reported for 
12.6% (83/658) of subjects. Serious GI irAEs, mostly involving diarrhea or colitis, were reported 
in 12.9% (85/658) of subjects treated with ipilimumab at 10 mg/kg. 
Inflammatory Hepatotoxicity
Immune-related hepatic dysfunction, including hepatitis or abnormal liver function tests (LFT) 
attributed to ipilimumab therapy, has been reported. Subjects may develop elevations in LFTs in 
the absence of clinical symptoms. Inflammatory hepatotoxicity includes non-infectious hepatitis 
(e.g., autoimmune hepatitis). Among subjects who received ipilimumab at 10 mg/kg, 
inflammatory hepatotoxicity of any grade was reported for 9.0% (59/658) of subjects, and Grade 
3 – 4 inflammatory hepatotoxicity was reported for 6.4% (42/658). Serious inflammatory 
hepatotoxicity has been reported in 5.0% (33/658) of subjects who received ipilimumab at 10 
mg/kg. Inflammatory hepatotoxicity is usually reversible when immediately treated with high-
dose steroids, if applicable, with or without additional immunosuppressants as recommended in 
the hepatotoxicity management algorithm presented as an appendix in the IB.

Hypophysitis/Hypopituitarism and Other Endocrine Conditions
Hypophysitis/hypopituitarism, clinically manifested by fatigue, has been reported. Most subjects 
with hypopituitarism presented with nonspecific complaints such as fatigue, confusion, visual 
disturbance, or impotence. Some had headache as the predominant presentation. The majority of 
subjects with hypopituitarism demonstrated enlarged pituitary glands based on brain magnetic 
resonance imaging (MRI). Low adrenocorticotropic hormone (ACTH) and cortisol were the most 
common biochemical abnormality reported; low thyroid stimulating hormone (TSH), 
testosterone, or prolactin was also reported in some subjects11.
Hypophysitis/hypopituitarism was controlled with appropriate hormone-replacement therapy and 
may be dose related. Among subjects who received ipilimumab at 10 mg/kg, endocrinopathy of 
any grade was reported for 7.6% (50/658) of subjects, and Grade 3-4 endocrinopathy was 
reported for 2.4% (16/658) of subjects. Serious drug-related endocrinopathy, such as 
hypophysitis/hypopituitarism, was reported in 3.2% (21/658) of subjects who received 
ipilimumab at 10 mg/kg.
The first onset of endocrine irAEs typically occurred between weeks 6 and 12 of treatment. 
Endocrine events were generally manageable with hormone-replacement therapy, and the 
majority of subjects were not weaned from steroids.
Rash and Other Skin Conditions
Rash was one of the most common irAEs, and most cases were Grade 1 or 2 in intensity; pruritus 
has also been reported12. When biopsied, pleomorphic infiltrates were noted in the skin. Among 
subject who received ipilimumab at 10 mg/kg, skin irAEs of any grade were reported for 52.9% 
(348/658) of subjects, and Grade 3 – 4 skin irAEs were reported for 2.9% (19/658) of subjects. 
Serious skin irAEs were reported in < 1% (4/658) of subjects who received ipilimumab at 10 
mg/kg. Skin irAEs were generally reversible. 
Other presumed irAEs reported include, but were not limited to, arthritis/arthralgias, 
pneumonitis, pancreatitis, autoimmune (aseptic) meningitis, autoimmune nephritis, pure red cell 
aplasia, non-infective myocarditis, ocular inflammation, Guillain-Barre syndrome (GBS), 
myasthenia gravis, and neuropathy (e.g., motor neuropathy, neuritis), of which were individually 
reported for < 1% of subjects. 
Other reported irAEs
Ocular inflammation, manifested as Grade 2 or Grade 3 episcleritis or uveitis, was associated 
with concomitant diarrhea in a few subjects and occasionally occurred in the absence of 
clinically apparent GI symptoms13. Serious ocular inflammation was reported in 1 of 658 (0.2%) 
subjects who received ipilimumab at 10 mg/kg (8 [0.3%] of 2901 subjects program-wide 
reported serious ocular inflammation). Preliminary analysis (based on the manual extraction of 
the SAE data from the internal safety database) indicated that the median time to event onset was 
approximately 61 days (range: 14 – 114 days). Based on the available data with known outcome, 
most of the subjects recovered or improved with or without corticosteroid therapy with a median 
duration of approximately 6 days (range: 5 – 23 days).
Management algorithms for general irAEs, and ipilimumab-related diarrhea, hepatotoxicity, 
endocrinopathy, and neuropathy are presented as appendices in this protocol.
Additionally, as of February 2006, there has been observation from a National Cancer Institute 
(NCI) study of bowel wall perforation in some patients who were administered a high-dose IL-2 

Version date: 1/09/2019
CC# 12557
Phase II – ipilimumab/sipuleucel-T
Page 17 of 84
following treatment with ipilimumab. Of the 22 patients administered high-dose IL-2, three 
patients experienced bowel wall perforations. This is a higher rate than would be expected with 
high-dose IL-2 treatment alone. All three patients had metastatic melanoma and had previously 
received their last dose of ipilimumab > 77 days before the first dose of IL-2. Two of the patients 
had clinically significant ipilimumab-related diarrhea or colitis and the symptoms had 
completely resolved prior to IL-2 administration. One patient did not experience ipilimumab-
related diarrhea. It is unknown whether this observation represents a true association or is 
mechanistically unrelated to prior ipilimumab exposure.
1.2.2.7
Drug-Related Deaths
Based on reports from the safety database as of June 30, 2009, there have been reports of death 
(approximately 1% [35/3800]), deemed by the investigator as possibly related to the 
administration of study drug. The most common cause of drug related deaths was GI perforation. 
Other causes included multiorgan failure, sepsis, hypotension, acidosis, and adult respiratory 
distress syndrome. For details on all drug-related deaths, refer to the current version of the 
Ipilimumab Investigator Brochure.
1.2.2.8
Safety of 10 mg/kg Multiple Doses
Based on a review of the program-wide SAE data as previously reported, evidence had suggested 
that ipilimumab-associated irAEs were dose dependent in frequency, and higher irAE rates had 
been observed at 10 mg/kg than at lower doses of ipilimumab. Subsequently, this dose-
dependent effect was further demonstrated in CA184-022 in which three dose levels of 
ipilimumab were studied, including 0.3 vs. 3 vs. 10 mg/kg. Table 3 summarizes the overall irAE 
frequencies by dose from CA184-022 based on safety data from the locked clinical database.

Neuropathies
Isolated cases of motor neuropathy of an autoimmune origin have been reported among patients 
treated with ipilimumab. Three cases have been diagnosed as Guillain-Barre syndrome (GBS), 
two of which were considered study related. In both cases, the GBS was atypical in nature and 
more clinically resembled polyneuritis. As of 30 June 2009, 27 cases of neuropathy SAEs have 
been reported. Of these, 22 were assessed as unrelated to study therapy because alternative 
etiologies, including brain metastases, spinal cord compression, arterial thrombosis, or platinum-
base chemotherapy were identified in almost every case.
1.2.3
 Clinical Efficacy of Ipilimumab
Treatment with ipilimumab has demonstrated clinically important and durable tumor responses 
in several malignancies including melanoma, prostate cancer, and renal cell carcinoma. The most 
extensively studied tumor type has been malignant melanoma and the principal demonstration of 
the efficacy of ipilimumab at the 10 mg/kg dose comes from 3 Phase 2 multicenter trials in 487 
subjects with advanced melanoma: CA184022, CA184008, and CA18400714.

Ipilimumab in Prostate Cancer Patients
Although Ipilimumab is a fully human anti-CTLA-4 IgG1 monoclonal antibody approved in the 
US for the treatment of unresectable advanced melanoma, it was in fact first administered to 
patients with prostate cancer. In this initial trial, a single dose of ipilimumab at 3mg/kg given to 
patients with hormone-refractory prostate cancer resulted in a ≥ 50% decline in PSA levels in 2 
of 14 patients, and <50% decline in 8 others 15. The two responders did not have measureable 
disease, but one developed grade 3 toxicity of an inflammatory nature (rash). Of the two other 
patients who had measureable disease at baseline that were evaluated by repeat radiographic 
imaging, neither demonstrated an objective response using the Response Evaluation Criteria in 
Solid Tumors (RECIST).  This trial showed that a single 3mg/kg dose of ipilimumab is tolerated 
but also indicated the risk of treatment-related immune events.
Overall, there have been ten clinical trials that are exploring the use of anti-CTLA-4 antibodies 
in the setting of prostate cancer. As a result of the data from TRAMP mice that were treated with 
anti-CTLA-4 antibodies combined with other treatments, six clinical trials have explored 
combinations with other immune adjuvants (GM-CSF), cancer vaccines (GVAX and 
PROSTVAC), chemotherapy, radiation and anti-androgen therapy. Although the studies are too 
small to be definitive, these trials overall have noted declines in PSA and a low frequency of 
radiographic responses at doses of ipilimumab ≥ 3mg/kg. Radiographic responses in prostate 
cancer can be difficult to detect because bone metastasis, which are common with prostate 
cancer, are difficult to measure. In a Phase I trial combining GM-CSF with escalating doses of 
ipilimumab, 22% of patients receiving ipilimumab ≥ 3mg/kg experienced a significant PSA 
response 16,17. At the time of this report, 1 patient had a partial objective response in liver 
metastases in accordance with RECIST. Combining cancer vaccines and ipilimumab would 
presumably improve anti-tumour activity by amplifying immune responses focused to relevant 
antigens as demonstrated in mice. In a trial investigating ipilimumab with GVAX, 5 of 28 
patients who completed treatment had a ≥ 50% decline in PSA, and 12 had stabilization of 
metastatic bone disease for extended durations (12 to 21 months) 18,19,20. PROSTVAC has also 
been combined with ipilimumab. In a randomized phase II trial, PROSTVAC alone significantly 
improved overall survival over placebo in healthy, well-performing patients with mAIPC 21. In 
the combination trial, 5 of 9 chemo-naïve patients with mAIPC who received 3 or 5 mg/kg of 
ipilimumab plus PROSTVAC had ≥ 50% declines in PSA 22. Overall 14 of 30 patients at any 
dose level of ipilimumab (1, 3, 5 and 10 mg/kg) had some decline in PSA. Physical tumor 
shrinkage however was infrequent. Of the previous 9 patients, 4 had stable disease ≥ 6 months, 
and 2 had unconfirmed partial responses. Nine of 15 receiving 10 mg/kg of ipilimumab had 
stable disease ≥ 6 months. Despite limited numbers of noticeable tumor shrinkage, both GVAX 
and PROSTVAC with ipilimumab trials showed a significant number of patients with 
stabilization of their disease under combination therapy that can last for several months and 
manageable side effects. However, further studies are required to see if the combination is more 
effective than either ipilimumab or vaccine alone.
In a phase II trial that combined ipilimumab with radiotherapy, no difference in the number of 
patients who had a decline in PSA ≥ 50% was seen between patients treated with ipilimumab 
alone (5 out of 16 chemo-naïve patients) versus the ipilimumab and radiotherapy(4 out of 15 
chemo-naïve patients),  and fewer patients in the post-chemotherapy group had a decline in PSA 
≥ 50%  when treated with ipilimumab and radiation (1 out of 14) 23,24. In a randomized phase II 

Version date: 1/09/2019
CC# 12557
Phase II – ipilimumab/sipuleucel-T
Page 20 of 84
trial comparing ipilimumab at 3mg/kg alone versus ipilimumab plus a single dose of docetaxel 
showed a limited number of PSA responses: 2 of 23 patients treated with ipilimumab alone and 1 
of 20 patients treated with the combination therapy25. There was no objective radiographic 
response observed at the time. However, in a randomized phase II trial of ipilimumab and 
androgen ablation, patients treated with ipilimumab and androgen ablation were more likely to 
have undetectable levels of PSA by 3 months (55% vs. 38%) 26. Another human IgG2 
monoclonal antibody (tremelimumab, Pfizer) has been tested in a phase I trial in combination 
with androgen deprivation in patients with PSA-recurrent non-metastatic prostate cancer but the 
results are not currently available at the time of writing (www.ClinicalTrials.gov, Identifier: 
NCT00702923) 27.
Blocking CTLA-4 in patients with prostate cancer revealed tumour response patterns not 
previously appreciated in inbred mouse models. For example, a decline in PSA levels can occur 
immediately after treatment but also after a period of stable disease or even after disease 
progression. For early phase trials, which are designed to capture early endpoints, such as safety 
or PSA responses, not enough time may have elapsed to see objective tumour responses by 
RECIST. Even so, more patients achieve disease stabilization rather than tumour shrinkage by 
radiographic assessment. One potential explanation is that AIPC mostly metastasizes to the bone, 
and bone lesions, whether regressing or progressing, are notoriously difficult to measure with 
current radiographic techniques. On the other hand, these response patterns have been 
consistently observed in patients with measureable metastases in advanced melanoma28, yet 
objective responses still remain low overall (~10%) 29.  If tumour control is sustained, however, 
patients may live longer. Indeed, the median overall survival in the PROSTVAC combination 
trial is 31.8 months 30, a significant duration in mAIPC, and in pre-treated metastatic melanoma, 
CTLA-4 blockade significantly improves survival by 4 months over gp100 vaccine, despite no 
improvement in time to progression or progression-free survival 7. 
1.2.4.1 
Rationale for 3 mg/kg Dose of Ipilimumab
Given this experience with CTLA-4 blockade in AIPC, two recent phase III trials have 
investigated ipilimumab in mAIPC with overall survival as the primary endpoint. The first study 
compared ipilimumab versus placebo in individuals with mAIPC who have not already been 
treated with chemotherapy.  The second trial compared ipilimumab following radiation therapy 
versus placebo following radiation therapy in patients who have already been treated with 
docetaxel chemotherapy for mAIPC.47  Both studies addressed as their primary endpoint whether 
patients live longer with CTLA-4 blockade than patients treated in the control arm.
While the second study in metastatic prostate cancer did not meet the primary endpoint of 
improving overall survival (HR=0.85, p=0.053), Ipilimumab demonstrated antitumor activity in 
other efficacy endpoints, including progression-free survival.  More importantly, safety was 
evaluated for all treated patients (pts; N=393 for ipilimumab 10 mg/kg, N=396 for placebo) 
starting from first study dose and ending 70 days after the last study dose, including maintenance 
dosing.  Any grade (Gr) irAEs occurred in 63.4% and 21.7% of patients in the ipililimumab and 
placebo arms, respectively. Most common Gr 3/4 irAEs were gastrointestinal (GI) (18.1%; 
mostly diarrhea and colitis). Deaths due to study drug toxicity, as per investigators, occurred in 4 
patients (4, ipilimumab and 0, placebo).

Page 21 of 84
Thus, based on the above safety data from the second phase III trial which showed severe irAEs, 
the most frequent being diarrhea and colitis, the dose of ipilimumab has been reduced from 10 
mg/kg to 3 mg/kg. 
1.3
Study Rationale
Multiple animal models have demonstrated additive or synergistic immunologic and anti-tumor 
effects in combining CTLA4 blockade with a vaccine 31-34. While these results provide a 
compelling rationale for pursuing a combination trial, a randomized trial to demonstrate a 
clinical advantage to combining CTLA4 blockade with SipT would require overall survival as 
the evaluable endpoint (because the clinical efficacy of SipT can only be demonstrated by overall 
survival, not TTP or response rate).  Two crucial issues must be addressed prior to pursuing such 
a trial: 1) safety of sequential treatment, and 2) timing of the ipilimumab administration.  
While the importance of demonstrating safety is obvious, the importance of timing is also 
crucial: in the proHA x TRAMP mouse model, initiation of CTLA4 blockade 1 day following 
vaccination was superior to initiation of CTLA4 blockade 4 days following vaccination in 
inducing T cell immune responses (Dr. Chuck Drake, Johns Hopkins, manuscript in progress, 
personal communication). With regards to SipT, the cellular product is known to also contain 
lymphocytes.  While characterization of this product is limited at present, CD54 upregulation 
represents one of the key release criteria for this cellular product.  While CD54 represents an 
activation marker on antigen presenting cells, it can also be an activation marker for 
lymphocytes.  We now know that in fact lymphocytes do also significantly upregulate CD54, 
particularly in the second and third doses of SipT.  This finding would suggest that activated T 
cells, which would express higher levels of CTLA4, may be contained in the product.  Therefore, 
these later cellular products may in fact represent antigen specific lymphocytes that have been 
primed in vivo (with the first dose) and expanded with the ex vivo culture (2nd and 3rd doses). If 
this is true, then CTLA4 blockade would be most effective at potentiating these T cells when 
given soon after the final SipT infusion.  Otherwise, if significant time elapses between infusion 
of SipT and CTLA4 blockade, then those activated (CTLA4-expressing) T cells induced in/by 
the product may already have encountered endogenous costimulatory molecules, and may thus 
have already triggered CTLA4-mediated down-modulation of their function.  Alternatively, 
immediate administration of ipilimumab with activated T cells may potentially increase the 
frequency of toxicities or the generation of adaptive regulatory T cells. 
Our trial design of studying sequential treatment with ipilimumab following SipT represents the 
schedule that is currently clinically feasible.  No data are available as to whether the presence of 
ipilimumab within a patient may alter the SipT product.  Because the sipT product has specific 
release criteria, SipT treatment will be completed prior to treatment with ipilimumab in order to 
not jeopardize the production the SipT.
PSA decline of > 50% was chosen as a secondary endpoint of this study given the difficulty of 
evaluating prostate cancer patients radiographically. Metastatic disease is primarily 
unmeasurable and bone scans rarely show the improvement that would reflect response and 
clinical benefit. To include only patients with measurable disease would limit the applicability of 
this therapy to a very limited subset of patients. Although PSA decline is not a widely accepted 
surrogate endpoint, it is often used as the primary endpoint in clinical studies.

Phase II – ipilimumab/sipuleucel-T
Page 22 of 84
Results from efficacy studies of ipilimumab in advanced melanoma have shown both the 3 and 
10 mg/kg ipilimumab doses are safe and effective.  Ipilimumab was approved in US and Europe 
at a dose of 3 mg/kg in adults patients with advanced melanoma based on a phase 3 study in 
patients with previously treated melanoma (MDX010-20). Ipilimumab 10 mg/kg was used in a 
second registrational study in adult patients with previously untreated advanced melanoma and 
prolonged overall survival when combined with DTIC, versus DTIC alone (CA184-024). A 
randomized phase 2 study in advanced melanoma (CA184-022) suggested  that10 mg/kg 
ipilimumab was potentially more active and was associated with increased toxicities relative to 3 
mg/kg dose. An ongoing phase 3 trial (CA184169) of 3 vs. 10 mg/kg ipilimumab will provide 
definitive answer regarding whether there is an optimal monotherapy dose in advanced 
melanoma.
The dosing interval for ipilimumab is based on the prior study which demonstrated drug levels ≥ 
10 mg/mL (a minimum level required for CTLA-4 blockade in pre-clinical models) for greater 
than 28 days. Four doses of ipilimumab given every 3 weeks were chosen because four doses 
have been given safely in other trials.

STUDY OBJECTIVES: PHASE II STUDY
2.1
Primary Objective

Determine whether the timing of ipilimumab administration impacts PAP and PA2024-
specific immune responses induced by SipT.
2.2
Secondary Objectives

Assess the safety associated with giving ipilimumab either immediately following 
completion of SipT or delayed ipilimumab following SipT.

Assess clinical activity of the combination therapy for each study arm in chemotherapy-
naïve patients with metastatic CRPC.

Determine whether the timing of ipilimumab administration impacts the 
immunomodulation of activated effector and regulatory T cells.

STUDY DESIGN
This is a non-comparative open-label randomized multicenter Phase 2 clinical trial administering 
ipilimumab following standard SipT treatment in patients with chemotherapy-naïve metastatic 
CRPC. Patients will be accrued at UCSF and MD Anderson. Patients are randomized so as to 
achieve uniform patient cohorts treated on each regimen. Twenty-seven evaluable patients will 
be required per treatment arm, and 54-66 prostate cancer patients will be required to complete 
this multicenter study. The study will assess for the immunogenicity and clinical activity of 
sipuleucel-T treatment followed by ipilimumab in chemotherapy-naïve patients with metastatic 
castrate resistant prostate cancer (CRPC).
All patients will be treated with standard SipT (Q2 wks x 3).  Patients will be randomized within 
2 weeks of their final dose of SipT to one of two arms:

Version date: 1/09/2019
CC# 12557
Phase II – ipilimumab/sipuleucel-T
Page 23 of 84
Arm 1 (Immediate Treatment)
Ipilimumab Q3 wks x 4 started 1 day following the final dose of SipT.
Arm 2 (Delayed Treatment)
Ipilimumab Q3 wks x 4 started 3 weeks following the final dose of SipT.
Following this “induction” ipilimumab treatment, patients will then be followed monthly for 3 
months and then quarterly (every 12 weeks) until disease progression. The definition of 
unacceptable toxicity is grade 3 or higher treatment-related toxicities (NCI CTCAE v4) 
excluding irAEs. Patients who experience an initial clinical responses to ipilimumab followed by 
subsequent disease progression will be offered reinduction treatment with ipilimumab.
Figure 1.  Dosing Schema
(Day 0)   
aRandomizaiton will be stratified by site and will occur within 2 weeks prior to the final Sip T 
dose.
3.1
Safety Analysis
Because SipT treatment is associated with minimal toxicity, and an active dose of ipilimumab 
has been established (no MTD has been defined) with tolerable side effects, we propose to 
perform a safety analysis with standard SipT treatment and the 3 mg/kg dose of ipilimumab. 
Twelve patients will be randomized to either of the 2 scheduling arms (immediate vs. delayed) (6 
per arm). After randomizing the initial 6 patients to each arm, the frequency and grade of AEs 
will be evaluated. 
3.2
Phase 2 Design
Once the ipilimumab dose is established for each study arm, the randomization between the 
immediate and delayed arms will resume accruing a total of 27 evaluable randomized patients 
per study arm. 
Randomized patients treated in the phase I at the same dose used in the Phase 2 study will be 
included for immune response analysis; thus patients accrued in the randomized component of 
the Phase I trial can be included for analysis of the study objectives.

Phase II – ipilimumab/sipuleucel-T
Page 24 of 84
Once written informed consent is obtained and the patient has undergone screening and 
determined to be eligible for the trial, treatment with SipT will begin. The patient will be 
randomly assigned following the second dose of SipT to one of the two treatment groups in a 1:1 
ratio using a block design to maintain a balance in treatment assignment. Randomization will be 
stratified by site (UCSF and MD Anderson).  The randomization will be performed by the study 
statistician at UCSF. At the time of randomization, a unique patient study identification number 
will be assigned to each patient. This study identification number must be included on all 
submitted forms and specimens.
Patients will receive induction treatment with 4 doses of ipilimumab on a 21-day cycle.  As 
durable disease stabilization and/or objective tumor response can be seen after early progression, 
it is recommended that, in the absence of dose-limiting toxicities, all four doses of ipilimumab be 
administered over the initial 12 weeks even in the setting of apparent clinical progression, 
providing the subject’s performance status remains stable.
All subjects who enter the induction period, including those who may have discontinued 
treatment for drug-related AEs and/or who have evidence of clinical progression during the 
induction period, should obtain a 12-week tumor assessment.
Clinical progression warranting alternative anti-cancer treatment should be considered only in 
subjects whose overall tumor burden appears to be substantially increased and/or in subjects 
whose performance status is decreased.
3.3
Reinduction Treatment
Patients who experience a clinical response to treatment during the first 12 weeks of ipilimumab 
treatment, but then develop subsequent progression of their disease after the initial 12 weeks of 
ipilimumab and who have not experienced unacceptable toxicity (refractory Grade > 3 irAEs) 
can be offered reinduction therapy with ipilimumab with up to 4 doses Q3 wks at the same dose 
level. 
Following discontinuation of study therapy, subjects will complete a 30-day off study visit and 
then enter into follow up. Subjects who discontinue ipilimumab treatments should be followed 
until death or closure of the study (whichever is first). Subjects who are no longer receiving 
ipilimumab because of clinical progression and who have switched to alternative treatment are 
not followed formally except to record the date of death.

will make the administration of ipilimumab hazardous or obscure the interpretation of 
AEs, such as a condition associated with frequent diarrhea.
4.3
Removal of Subjects from Assessment
Subjects should remain on study and continue with protocol-specified tests and evaluations 
whenever possible.  The Investigator may withdraw a subject from treatment or assessment at 
any time if, in his or her clinical judgment, it is in the best interest of the subject.
Subjects may discontinue their participation in the trial at any time without prejudice.  If a 
subject chooses to withdraw early from the study, the Investigator should make every reasonable 
attempt to ensure that early withdrawal procedures are completed and to determine the reason for 
withdrawal.  The date and reason for withdrawal will be recorded in the source documentation 
and on the CRF.
Patients will have monthly follow-up visits for 3-months after the last Ipilimumab dose and then 
Q 3 months until disease progression as defined in section 7.1.
4.3.1
Subject Follow-Up after Study Completion or Discontinuation
All AEs ongoing at the time of study completion or discontinuation that are considered by the 
Investigator to be clinically significant and related to study drugs will be followed until 
resolution, until the condition is deemed unlikely to improve, or until the subject is deemed lost 
to follow-up.

STUDY THERAPY
Sipuleucel-T is an autologous active cellular immunotherapy product designed to stimulate an 
immune response against prostate cancer.  It consists of autologous peripheral blood 
mononuclear cells (PBMCs), including APCs that have been activated in vitro with a 
recombinant fusion protein composed of PAP, an antigen expressed in prostate adenocarcinoma, 

Version date: 1/09/2019
CC# 12557
Phase II – ipilimumab/sipuleucel-T
Page 28 of 84
linked to GM-CSF, an immune cell activator.  A dose of sipuleucel-T is prepared from cells from 
a single leukapheresis procedure.  each dose contains a minimum of 50 million autologous 
CD54+ cells activated with PAP-GM-CSF.  Three planned doses of sipuleucel-T will be 
administered via IV infusion at 2-week intervals.  
Following sipuleucel-T treatment, patients will receive ipilimumab either on the following day 
(immediate cohort) or 3 weeks later (delayed cohort).  Ipilimumab is an anti human CTLA-4 
monoclonal antibody. CTLA-4 interaction with the B7 molecule, one of its ligands expressed on 
antigen presenting cells, can down-regulate T-cell response. Ipilimumab is thought to act by 
blocking the interaction of CTLA-4 with the B7 ligand, resulting in a blockade of this 
immunologic checkpoint, thereby enhancing antigen-specific immune responses. 
5.1
Sipuleucel-T (Provenge®, Dendreon Corporation)
Sipuleucel-T is an autologous cell product consisting of APCs loaded with prostate antigen 
PA2024.  PA2024 is a recombinant fusion protein composed of PAP, an antigen expressed in 
prostate adenocarcinoma, linked to GM-CSF, an immune cell activator.  Overall, 
immunohistochemistry and RNA probes suggest that PAP is generally an organ-specific prostate 
antigen and is highly expressed in normal and malignant prostate cells.  However, there is 
evidence for expression of PAP in normal kidney cells, the islets cells of normal pancreas, and 
hair follicles 41,42.  The results from a quantitative polymerase chain reaction (PCR) study by 
Cunha et al. suggest that PAP transcript is expressed at low levels in several normal tissues 43.  
They found low but detectable levels of mRNA, most notably in placenta, kidney, and testis.  
The kidney expression levels were 192-fold less than that seen in normal prostate tissue.  The 
pancreas, small intestine, leukocytes, and to an even lesser degree, lung, ovary, colon, and spleen 
also exhibited very low but detectable levels of PAP transcripts.  There are also reports in the 
literature suggesting that PAP is expressed in certain non-prostate-derived malignancies.  For 
example, Wang et al. present immunohistochemical data that suggest PAP is expressed in colon, 
breast, and gastric tumors, but not the corresponding normal tissues 44.
The cDNA for PAP has been isolated.  The analysis of sequence homology with other known 
proteins suggests a low risk of cross-reactivity of immune responses.  GM-CSF is a multilineage 
factor that may also activate mature granulocytes and macrophages, and may activate quiescent 
APCs.
Preparation of sipuleucel-T entails isolating quiescent APCs from a subject’s peripheral blood 
leukapheresis product by buoyant density techniques and then culturing them for approximately 
2 days in the presence of PA2024.  The culture medium does not contain serum or exogenous 
cytokines.  During the culture process, APCs specifically and selectively pick up antigen 
(PA2024) and differentiate into antigen loaded APCs capable of presenting antigen to T cells.  
These APCs thus represent the cells responsible for the biological activity of sipuleucel-T.  Other 
cell populations in sipuleucel-T co-purify with APCs during buoyant density centrifugation, but 
do not incorporate or present antigen, and are therefore referred to as “non-APCs.”  After the 
culture period, the cells are washed and suspended in Lactated Ringer’s Injection, USP.  The 
final preparation of PA2024-loaded APCs is designated sipuleucel-T.  Sipuleucel-T is placed in a 
refrigerated package and transported to the clinical research center for infusion.
Further information regarding the manufacture and characterization of sipuleucel-T is provided 
in the sipuleucel-T Investigator’s Brochure.

5.1.1
Preparation of Sipuleucel-T
Leukapheresis and Collection of PBMCs 
Subjects undergo a standard 1.5 to 2.0 total blood volume leukapheresis to harvest PBMCs 
(primarily lymphocytes and monocytes).  Prior mobilization with a colony-stimulating factor is 
not performed.  Immediately after collection, the leukapheresis product is transported to a 
manufacturing facility.
Quality Control Testing
Quality control (QC) testing is performed at several time points during the manufacturing 
process and on samples of the final product.  If the final product passes all required release tests, 
an approval to infuse the product (Cell Product Disposition Form) is faxed to the infusion center.  
If a cell product does not meet Dendreon quality specifications, Dendreon will contact the 
infusion center by telephone and by fax.  Dendreon will provide instructions for product return or 
destruction of cell products that are not approved or not infused.
Storage and Time Limitation
Sipuleucel-T should be maintained in the refrigerated shipping package until infused.  The 
infusion of sipuleucel-T must begin prior to the expiration time indicated on the product label.  
Expired cell products must not be infused.
Chain of Identity
Because sipuleucel-T is an autologous blood product, access to subject identifying information is 
critical to ensure subject safety.  To maintain the chain of identity and thereby ensure subject 
safety, a label that contains subject identifying information accompanies the product.  This label 
is completed by medical personnel performing the leukapheresis procedure.  The subject-specific 
label will accompany the cell product throughout the manufacturing process and will accompany 
the cell product to the study center.  Therefore, the subject’s identifying information will be 
revealed to manufacturing facility staff and to Dendreon’s manufacturing department.
Infusion - Sipuleucel-T is to be administered per institutional guidelines (suggestions below)
Subjects will be premedicated with acetaminophen and an antihistamine such as 
diphenhydramine prior to each infusion of sipuleucel-T. The infusion will be administered over 
approximately 30 to 60 minutes through an IV line suitable for blood transfusion (without a cell 
filter).  Common treatment-emergent AEs, such as pyrexia, chills, fatigue, nausea, and joint ache 
and/or rigors, may warrant reduction of the infusion rate.  
In the event of an acute infusion reaction, the infusion may be interrupted or slowed, depending 
on the severity of the reaction.  Appropriate medical therapy should be administered as needed.  
In controlled clinical trials, symptoms of acute infusion reactions were treated with 
acetaminophen, intravenous H1 and/or H2 blockers, and low dose intravenous meperidine.  If the 
infusion of sipuleucel-T must be interrupted, the infusion should not be resumed if the 
sipuleucel-T infusion bag will be held at room temperature for more than 3 hours.
Subjects will be observed for at least 30 minutes following the infusion.

5.2
Ipilimumab (Yervoy®, BMS)
Ipilimumab is a human monoclonal antibody specific for the CTLA-4 antigen expressed on a 
subset of activated T-cells. CTLA-4 interaction with the B7 molecule, one of its ligands 
expressed on antigen presenting cells, can down-regulate T-cell response. Ipilimumab is thought 
to act by blocking the interaction of CTLA-4 with the B7 ligand, resulting in a blockade of the 
inhibitory effect of T-cell activation that is created by the CTLA-4/B7 interaction. 
5.2.1
Dose Calculations
Ipilimumab dosing will be based on actual weight All patients will receive ipilimumab 3 mg/kg 
dosed IV over 90 minutes every 3 weeks for 4 doses as induction treatment. In the event that a 
patient responds to treatment, and then subsequently progress, the patient may receive 
reinduction treatment.
5.2.2
Provision of Drug
Ipilimumab is supplied by the study in single-use, glass vials as a sterile, colorless solution for 
intravenous administration containing 200 mg or 50 mg.
5.3
Dose Modifications
5.3.1
Sipuleucel-T Modifications
A subject may not receive all 3 infusions of sipuleucel-T if any of the following occurs prior to 
completion of the treatment regimen: 

The subject develops an unacceptable toxicity (defined as  National Cancer Institute 
Common Terminology Criteria for Adverse Events (NCI CTCAE) Grade 3 toxicity) deemed 
by the Investigator as possibly or probably related to infusion with sipuleucel-T, with the 
exception of the following Grade 3 events: pyrexia, fatigue, asthenia; 

The subject develops a concurrent illness that prevents further administration of sipuleucel-T;

The subject elects not to receive all 3 infusions of sipuleucel-T or withdraws consent;

It is determined that it is not possible to manufacture sipuleucel-T that will pass QC testing; 

At the discretion of the Investigator.
Subjects who receive fewer than 2 infusions of sipuleucel-T due to any of the reasons noted 
above will continue to be followed for 12 weeks, but will not be randomized for ipilimumab 
treatment and will be replaced.  
Patients are randomized after the second sipuleucel-T infusion. If the second infusion cannot be 
administered, then the patient will not be randomized and will be replaced.  This will not affect 
the evaluation of the primary study aim.  If the patient is randomized but does not receive the 
third sipuleucel-T infusion for any of the reasons listed above, this patient will be replaced.  The 
frequency of such an occurrence will be monitored. Patients must receive 3 doses of sipuleucel-T 
over a maximum of 10 weeks in order to continue in the study and receive ipilimumab.

5.3.2
Ipilimumab Modifications
Ipilimumab doses that cannot be given on schedule due to treatment-related adverse events will 
be skipped.  No dose adjustments or delay will be allowed for treatment-related adverse events. 
Decisions to skip an ipilimumab dose must be made on specified safety criteria. Treatment with 
ipilimumab will be skipped or discontinued if the subject experiences at least one adverse event, 
specified below, considered by the investigator to be “possibly”, probably” or “definitely” 
related to ipilimumab treatment. 
Study drug dosing will be skipped for the following treatment-related adverse event(s):

Any ≥ Grade 2 non-skin, treatment-related adverse event (including irAEs), except for 
laboratory abnormalities

Any ≥ Grade 3 treatment-related laboratory non-hematologic abnormality

Any adverse event, laboratory abnormality or intercurrent illness that, in the judgment of 
the investigator, presents a substantial clinical risk to the subject with continued dosing
It is necessary to skip study drug dosing for the following adverse events:

Any ≥ Grade 3 skin related adverse event regardless of causality
Restart ipilimumab dosing if/when the adverse event(s) resolve(s) to ≤ Grade 1 severity or 
returns to baseline within 2 weeks of the last ipilimumab dose:
If the adverse event has resolved, restart ipilimumab dosing at the next scheduled time point per 
protocol. 
If the adverse event has not resolved in time for the next dose (3 weeks ±3 days), the next 
scheduled dose will be skipped and dosing will be resumed at the subsequently scheduled dose. 
Withhold of ipilimumab for longer than 60 days after the scheduled dose will lead to permanent 
discontinuation. Toxicities, which cause dosing delays > 60 days will be considered sufficiently 
serious to lead to permanent discontinuation (not allowing for re-induction).
If > 1 dose is expected to be skipped, the dosing schedule modifications must be discussed with 
the principal investigator prior to implementation. 
5.4
Management of Toxicity
5.4.1
General Guidelines for Managing Toxicity
For ipilimumab, dose skipping should occur for any toxicity > grade 3 that is determined to be 
possibly, probably or definitely related to either of the study drugs.  Please refer to the AE 
Management Algorithms provided in the Investigator Brochure for guidance on management of 
potentially ipilimumab-related adverse events.  Toxicities must have resolved to < grade 1 before 
resuming therapy.

5.4.2
Hypersensitivity Reactions
Since ipilimumab contains only human protein sequences, it is less likely that any allergic 
reaction will be seen in patients. However, it is possible that infusion of ipilimumab will induce a 
cytokine release syndrome that could be evidenced by fever, chills, rigors, rash, pruritus, 
hypotension, hypertension, bronchospasm, or other symptoms. No prophylactic pre-medication 
will be given unless indicated by previous experience in an individual patient. Reactions should 
be treated based upon the following recommendations or per institutional protocol.
For mild symptoms (e.g., localized cutaneous reactions such as mild pruritus, flushing, rash):

Decrease the rate of infusion until recovery from symptoms, remain at bedside and 
monitor patient.

Complete the ipilimumab infusion at the initial planned rate.

Diphenhydramine 50 mg IV may be administered at the discretion of the treating 
physician and patients may receive additional doses with close monitoring.

Premedication with diphenhydramine may be given at the discretion of the investigator 
for subsequent doses of ipilimumab.
For moderate symptoms (any symptom not listed above as mild symptoms; or below as severe 
symptoms, such as generalized pruritus, flushing, rash, dyspnea, and hypotension with systolic 
BP >80 mmHg): 

Interrupt ipilimumab.

Administer diphenhydramine 50 mg IV.

Monitor patient closely until resolution of symptoms.

Corticosteroids may abrogate any beneficial immunologic effect, but may be 
administered at the discretion of the treating physician.

Resume ipilimumab infusion after recovery of symptoms.

At the discretion of the treating physician, ipilimumab infusion may be resumed at one 
half the initial infusion rate, then increased incrementally to the initial infusion rate. If 
symptoms develop after resumption of the infusion, the infusion should be discontinued 
and no additional ipilimumab should be administered that day.

The next dose of ipilimumab will be administered at its next scheduled time and may be 
given with pre-medication (diphenhydramine and acetaminophen) and careful monitoring, 
following the same treatment guidelines outlined above. At the discretion of the treating 
physician additional oral or IV antihistamine may be administered prior to dosing with 
ipilimumab.
For severe symptoms (e.g., any reaction such as bronchospasm, generalized urticarial, systolic 
blood pressure  80 mm Hg, or angioedema):

Immediately discontinue infusion of ipilimumab, and disconnect infusion tubing from the 
subject.


Patients should be monitored until the investigator is comfortable that the symptoms will 
not recur.

No further ipilimumab will be administered.
In case of late-occurring hypersensitivity symptoms (e.g., appearance within one week after 
treatment of a localized or generalized pruritus), symptomatic treatment may be given (e.g., oral 
antihistamine, or corticosteroids).
5.4.3
Management of Hepatotoxicity
Liver function tests (AST, ALT, T. bilirubin) will be evaluated for every subject prior to 
administration of ipilimumab. Blood samples must be collected and analyzed at local or central 
labs within 3 days prior to dosing. LFT results must be reviewed by the principal investigator (or 
designee) to meet dosing criteria specifications:  2.5 x ULN for AST, ALT and  1.5 x ULN for 
T. bilirubin unless liver metastases are present in which case LFT  5 x ULN for AST, ALT and 
T. bilirubin  3.0 x ULN) prior to dosing.
If, during the course of treatment abnormal LFT values are detected, the subject must be 
managed using the hepatotoxicity algorithm section in the appendix.
5.4.4
Treatment of Ipilimumab-Related Isolated Drug Fever
In the event of isolated drug fever, the investigator must use clinical judgment to determine if the 
fever is related to the ipilimumab or to an infectious etiology. If a patient experiences isolated 
drug fever, for the next dose, pre-treatment with acetaminophen or non-steroidal anti-
inflammatory agent (investigator discretion) should be instituted and a repeated antipyretic dose 
at 6 and 12 hours after ipilimumab infusion, should be administered. The infusion rate will 
remain unchanged for future doses. If a patient experiences recurrent isolated drug fever 
following premedication and post dosing with an appropriate antipyretic, the infusion rate for 
subsequent dosing should be decreased to 50% of the previous rate. If fever recurs following 
infusion rate change, the investigator should assess the patient’s level of discomfort with the 
event and use clinical judgment to determine if the patient should receive further ipilimumab.
5.4.5
Immune Related Toxicity
Blocking CTLA-4 function may permit the emergence of auto-reactive T cells and resultant 
clinical autoimmunity. Rash/vitiligo, diarrhea/colitis, uveitis/episcleritis, hepatitis, and 
hypopituitarism were drug-related, presumptive autoimmune events, now termed irAEs, noted in 
previous ipilimumab studies.
For the purposes of this study, an irAE is defined as an AE of unknown etiology associated with 
drug exposure and consistent with an immune phenomenon. Efforts should be made to rule out 
neoplastic, infectious, metabolic, toxin or other etiologic causes prior to labeling an AE an irAE. 
Serological, immunological, and histological (biopsy) data should be used to support the 
diagnosis of an immune-mediated toxicity. Suspected irAEs must be documented on an AE or 
SAE form. 

Version date: 1/09/2019
CC# 12557
Phase II – ipilimumab/sipuleucel-T
Page 34 of 84
Patients should be informed of and carefully monitored for evidence of clinically significant 
systemic irAE (e.g., systemic lupus erythematosus-like diseases) or organ-specific irAE (e.g., 
rash, colitis, uveitis, hepatitis or thyroid disease). If an irAE is noted, appropriate work-up 
(including biopsy if possible) should be performed, and steroid therapy may be considered if 
clinically necessary.  
It is unknown if systemic corticosteroid therapy has an attenuating effect on ipilimumab activity. 
However, clinical anti-tumor responses have been maintained in patients treated with 
corticosteroids and discontinued from ipilimumab. If utilized, corticosteroid therapy should be 
individualized for each patient. Prior experience suggests that colitis manifested as ≥ Grade 3 
diarrhea requires corticosteroid treatment.
The most common immune-related adverse events are dermatologic, endocrine, gastrointestinal, 
and hepatic.  For any suspected immune-related adverse event, begin with the algorithm in the 
Appendix.  For diarrhea, hepatotoxicity, or endocrinopathy, this will refer the investigator to a 
more specific algorithm (see Appendix).  For rash, see the below.
Skin related AE
Fatal toxic epidermal necrolysis (TEN) has been reported following a grade 3 skin-related AE, 
which was considered unrelated to ipilimumab on a Bristol-Myers Squibb-sponsored trial.  In 
patients with a drug-related Grade 2 skin immune-mediated toxicity or Grade 3 skin-related 
adverse event, regardless of causality, additional treatment will be delayed until the event 
improves to ≤ Grade 1 severity. 
In patients with drug-unrelated grade 2 skin-related adverse events, no dosing delay is required.  
Patient with a Grade 1 skin AE, regardless of causality, are to be treated per institutional 
guidelines.
A dermatologist should evaluate persistent or severe rash or pruritus. A biopsy should be 
performed if appropriate and if possible, photos of the rash should also be obtained. Low grade 
ipilimumab-mediated rash and pruritus were treated with symptomatic therapy (e.g., 
antihistamines). Topical or parenteral corticosteroids may be required for more severe 
symptoms. With the appearance of any generalized rash, concomitant medications (e.g.. 
antibiotics, anticonvulsants, or proton pump inhibitors) that may be associated with severe skin 
reactions (e.g., Stevens Johnson Syndrome, TEN) should be discontinued and avoided.  
Ipilimumab should also be held.
Specific treatment algorithms for immune-related adverse events are included as appendices to 
this protocol.
5.4.6
Discontinuation of Ipilimumab Treatment
The following treatment-related non-neurological adverse events require permanent 
discontinuation of ipilimumab:

Any ≥ Grade 2 eye pain or reduction of visual acuity that does not respond to topical 
therapy and does not improve to ≤ Grade 1 severity within 2 weeks of starting therapy, 
OR requires systemic treatment.

Any ≥ Grade 3 bronchospasm or other hypersensitivity reaction.

Version date: 1/09/2019

Phase II – ipilimumab/sipuleucel-T
Page 35 of 84

Any other ≥ Grade 3 non-skin related adverse event with the exception of events listed 
below under “Exceptions to Permanent Discontinuation”.

Any ≥ Grade 4 laboratory abnormalities, except AST, ALT, or Total Bilirubin

AST or ALT > 5 x ULN

Total Bilirubin > 3 x ULN

Any other ≥ Grade 4 adverse event 

Withhold of ipilimumab for greater than 60 days due to treatment related toxicity

Any adverse event, laboratory abnormality or intercurrent illness, which, in the judgment 
of the investigator, presents a substantial clinical risk to the patient with continued dosing. 

The development of progression in the global tumor burden and/or clinical deterioration of 
subject’s condition such that further benefit from ipilimumab dosing is unlikely or 
requires a change of therapy.
The following neurological adverse event requires permanent discontinuation of 
ipilimumab and defines unacceptable neurotoxicity:

Any motor neurologic toxicity >Grade 3 regardless of causality

Any > Grade 3 treatment related sensory neurologic toxicity
Please refer to the Appendices for specific treatment algorithms. 
5.4.6.1
Exceptions to Permanent Discontinuation 

Potentially reversible inflammation (< Grade 4), attributable to a local anti-tumor reaction 
and a potential therapeutic response. This includes inflammatory reactions at sites of tumor 
resections or in draining lymph nodes, or at sites suspicious for, but not diagnostic of 
metastasis.

Hospitalization for ≤ Grade 2 adverse events where the primary reason for hospitalization is 
to expedite the clinical work-up.

Patients with the following conditions where in the investigator’s opinion continuing study 
drug administration is justified:

Ocular toxicity that has responded to topical therapy.

Endocrinopathies where clinical symptoms are controlled with appropriate hormone 
replacement therapy. Note: Ipilimumab may not be restarted while the patient is being 
treated with systemic corticosteroids except for patients on stable doses of hormone 
replacement therapy such as hydrocortisone.
5.5
Prohibited Therapies During the Study
Patients in this study may not use vaccines for the treatment of cancer or prevention of disease 
unless indicated as a component of the protocol regimen (including those for common medical

conditions) for up to one month pre- and post-dosing with ipilimumab. Concomitant systemic or 
local anti-cancer medications or treatments are prohibited in this study while receiving 
ipilimumab treatments. Bone targeted agents (e.g. zolendronate, denosumab) are allowed. 
Patients may not use any of the following therapies during the study:

Any non-study anti-cancer agent (investigational or non-investigational)

Any other investigational agents

Any other (non-CA184024 related) CTLA-4 inhibitors or agonists

Immunosuppressive agents

Chronic systemic corticosteroids
Patients should receive full supportive care, including transfusions of blood and blood products, 
erythropoietin, antibiotics, antiemetics, etc., when appropriate. Treatment with hormones or other 
chemotherapeutic agents may not be administered except for hormones administered for non-
disease-related conditions (e.g., insulin for diabetes mellitus) and continued LHRH agonist 
therapy. Palliative radiation therapy may not be administered during protocol treatment. No 
steroids, except as directed by the protocol, for immune events or for severe hypersensitivity 
reactions, are allowed.

EFFICACY AND SAFETY ASSESSMENTS
7.1
Efficacy Assessment
7.1.1
Immune Response Endpoints
The primary immune study hypothesis is to assess the frequency of observing an IgG antibody 
response to PAP and/or PA2024 at baseline and at week 20 for each of the two ipilimumab 
schedules. The IgM and IgG antibody responses to PAP and PA2024 will both be assessed with 
an ELISA assay at baseline and week 20 after the start of protocol therapy. T cell responses to 
PAP and PA2024 will be assessed with an ELISPOT assay at baseline and at week 20 after the 
start of protocol therapy.
7.1.2
Clinical Response Endpoints
Ipilimumab is expected to trigger immune-mediated responses, which require activation of the 
immune system prior to the observation of clinical responses. Such immune activation may take 
weeks to months to be evident. Some patients have had objective volume increase of tumor 
lesions or other disease parameters within 12 weeks following the start of ipilimumab, which is 

Version date: 08/07/2019
Phase II – ipilimumab/sipuleucel-T
Page 43 of 84
subsequently followed by objective clinical responses 9,45. Early in the treatment, patients may 
not have had sufficient time to develop the required immune activation or, in some patients, 
tumor volume or other disease parameter increases may represent infiltration of lymphocytes into 
the original tumor or blood. In conventional studies, such tumor volume or relevant laboratory 
parameter increases during the first 12 weeks of the study would constitute PD and lead to 
discontinuation of treatment as well as subsequent imaging to detect response, thus disregarding 
the potential for subsequent immune-mediated clinical response. 
Therefore, patients with tumor volume increase detected or lack of laboratory parameter 
response documentation prior to week 12 but without rapid clinical deterioration should continue 
on treatment with ipilimumab and continue to be imaged to allow detection of a subsequent 
tumor response. This will improve the overall assessment of the clinical activity or ipilimumab 
and will more likely capture its true potential to induce clinical responses. Clinical assessment 
will be made using PSA response and radiographic response using standard irRC.9
7.1.3
Clinical Efficacy Evaluation
Patients will have PSA measurements on day 1 of every cycle prior to treatment. PSA decline 
will be evaluated according to the recommendations from PSA Working Group (PSAWG)39. 
Although response in this study is defined as a PSA decline, progressive disease is defined as 
progression by either PSA or objective progression. Bone scans and CT scans will be repeated 
every 12 weeks and at the time of PSA progression. Each category (measurable, non-measurable, 
and PSA) will be assessed and reported independently. Measurable disease/target lesions and 
non-measurable disease/non-target lesions will be evaluated according to the irRC. 9 
7.1.3.1
Definition of PSA Decline
All patients, with or without measurable disease, will be evaluated for PSA decline.
Patients with disease that is not measurable will be eligible for this study and will be assessed for 
response based on changes in PSA and serial bone scans. The baseline serum PSA must be at 
least 2 ng/mL.
30% PSA Decline: PSA decline of at least 30% from baseline confirmed by a second 
measurement at least 4 weeks later. The reference for these declines should be a PSA measured 
within 2 weeks prior to starting therapy. 
50% PSA Decline: PSA decline of at least 50% from baseline confirmed by a second 
measurement at least 4 weeks later. The reference for these declines should be a PSA measured 
within 2 weeks prior to starting therapy. 
PSA Progression: If at least a 50% PSA decline has been achieved, PSA progression occurs 
when the PSA has increased to 25% above the nadir and the increase in the absolute-value PSA 
level is at least 2 ng/mL, or back to baseline, whichever is lower, on at least 2 consecutive 
measurements at least 1 weeks apart. For patients without a PSA decline of this magnitude, or 
without any decline in PSA, progression will be defined by a 25% increase over baseline or nadir 
PSA (whichever is lower) and an increase in the absolute value PSA level by at least 2 ng/mL, 
on at least 2 consecutive measurements, after 12 weeks of therapy. For all patients without 
SigAEs, PSA and/or objective progression will not require the patient to discontinue study 
treatment until at least three cycles of therapy have been administered.

Version date: 08/07/2019
Phase II – ipilimumab/sipuleucel-T
Page 44 of 84
PSA Decline Duration: The PSA decline duration commences on the date of the first 50% 
decline in PSA. The response duration ends when the PSA value increases by 50% above the 
nadir, provided that the increase in the absolute-value PSA level is at least 2 ng/mL or back to 
baseline, whichever is lower.  If a patient does not progress for the duration of the study, his data 
will be censored at the time of last PSA follow-up.
Progressive Disease: Defined by PSA progression or by objective progression (based on RECIST 
1.1 criteria or the appearance of two or more new lesions on bone scan, confirmed 6 or more 
weeks later) more than three months after the initiation of therapy. Although response in this 
study is defined as a PSA decline, progressive disease is defined as progression by either PSA or 
objective progression. 
Time to PSA Progression: The start of the time to PSA progression is the day treatment is 
initiated. The end date is the time of PSA progression as defined above.  If a patient does not 
progress for the duration of the study, his data will be censored at the time of last PSA follow-up.
7.1.3.2
Definition of Measurable and Non-Measurable Lesions
Measurable Disease/Target Lesions 
All measurable lesions (lesions that can be accurately measured in at least one dimension, 
longest diameter to be recorded, as ≥10 mm with spiral CT) up to a maximum of 5 lesions per 
organ and 10 lesions total, representative of all involved organs, should be identified as target 
lesions and recorded and measured at baseline. Target lesions should be selected on the basis of 
their size (lesions with the longest diameter) and the suitability for accurate repeated 
measurements (either by imaging techniques or clinically). The sum of the products of the two 
largest perpendicular diameters (SPD) of all index lesions (5 lesions per organ, up to 10 visceral 
lesions) is calculated. At each subsequent tumor assessment, the SPD of the index lesions and of 
new, measurable lesions (≥5 × 5 mm; up to 5 new lesions per organ and 10 visceral lesions) are 
added together to provide the total tumor burden:
.
The overall response according to the irRC is derived from time-point response assessments 
(based on tumor burden) as follows:

Complete Response (CR): complete disappearance of all lesions (whether measurable or 
not, and no new lesions)
-
confirmation by a repeat, consecutive assessment no less than 4 wks from the date 
first documented

Partial Response (PR), decrease in tumor burden ≥50% relative to baseline
-
confirmed by a consecutive assessment at least 4 wks after first documentation

Stable Disease (SD), not meeting criteria for CR or PR, in absence of PD

Progressive Disease (PD), increase in tumor burden ≥25% relative to nadir (minimum 
recorded tumor burden)
-
confirmation by a repeat, consecutive assessment no less than 4 wks from the date 
first documented

Version date: 08/07/2019
Phase II – ipilimumab/sipuleucel-T
Page 45 of 84
Patients were considered to have PR or SD even if new lesions were present, as long as they met 
the respective thresholds of response as described above. Furthermore, patients were not 
considered to have PD if new lesions were present and the tumor burden of all lesions did not 
increase by ≥25%. In contrast to CR, PR, and PD, a response of SD does not require 
confirmation. It is important to note that CR, PR, and SD include all patients with CR, PR, or SD 
by WHO criteria as well as those patients that shift to these irRC categories from WHO PD. 
Patients with SD, particularly those with slow-declining tumor burden ≥25% from baseline at the 
last tumor assessment, are considered clinically meaningful because they show an objectively 
measurable reduction in tumor burden without reaching the 50% threshold that defines PR (it 
represented an objectively measured reduction not commonly observed in the natural history of 
advanced melanoma patients). 
Confirmation: To be assigned a status of PR or CR, changes in tumor measurements must be 
confirmed by repeat studies no less than 4 weeks after the criteria for response are first met 
Duration of overall response: The duration of overall response is measured from the time 
measurement criteria are met for CR/PR (whichever is first recorded) until the first date that 
recurrent or progressive disease is objectively documented (taking as reference for progressive 
disease the smallest measurements recorded since the treatment started). 
Non-measurable Disease/Non-Target Lesions
All non-measurable lesions (including small lesions, longest diameter < 20 mm with 
conventional techniques or < 10 mm with spiral CT scan and truly non-measurable lesions such 
as bone lesions) should be identified as non-target lesions and should also be recorded at 
baseline. Measurements of these lesions are not required, but the presence or absence of each 
should be noted throughout follow-up. 
Complete Response (CR): The disappearance of all non-target lesions
Incomplete Response/Stable Disease (IR/SD): The persistence of one or more non-target 
lesion(s) without unequivocal progression of existing non-target lesions
Progressive Disease (PD): The appearance of one or more new lesions and/or unequivocal 
progression of existing non-target lesions.  For bone scans, the appearance of 2 or more new 
lesions is required.  These lesions should be re-evaluated 6 or more weeks later to confirm 
progressive disease. Increased intensity of uptake in previously abnormal areas on bone scans is 
not considered progressive disease, unless the lesions seen on the correlative imaging studies 
performed of this area meet the criteria for progression. 
7.2
Safety Assessments
All patients who receive at least one dose of ipilimumab will be considered evaluable for safety 
parameters. Additionally, any occurrence of non-serious or SAE from time of consent forward, 
up to and including follow-up visits, will be reported. 
Safety will be evaluated for all treated patients using the National Cancer Institute (NCI) 
Common Terminology Criteria for Adverse Events (CTCAE), Version 4 (http://ctep.cancer.gov). 
Safety assessments will be based on medical review of adverse event reports and the results of 
vital sign measurements, physical examinations, and clinical laboratory tests.

7.3
Adverse Event Reporting
An adverse event (also known as an adverse experience) is defined as any untoward medical 
occurrence associated with the use of a drug in humans, whether or not considered drug related.  
More specifically, an adverse event (can be any unfavorable and unintended sign (e.g., an 
abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, 
without any judgment about causality.  An adverse event can arise from any use of the drug (e.g., 
off-label use, use in combination with another drug) and from any route of administration, 
formulation, or dose, including an overdose.
Adverse events can be spontaneously reported or elicited during open-ended questioning, 
examination, or evaluation of a subject. (In order to prevent reporting bias, subjects should not be 
questioned regarding the specific occurrence of one or more AEs.)
7.3.1
Serious Adverse Events
A serious adverse event (SAE) is any untoward medical occurrence that at any dose: 

results in death

is life-threatening (defined as an event in which the subject was at risk of death at the time of 
the event; it does not refer to an event that hypothetically might have caused death if it were 
more severe)

requires inpatient hospitalization or causes prolongation of existing hospitalization (see 
“note” below for exceptions)

results in persistent or significant disability/incapacity

is a congenital anomaly/birth defect

Suspected transmission of an infectious agent (e.g., any organism, virus or infectious particle, 
pathogenic or non-pathogenic) via the study drug is an SAE.

is an important medical event (defined as a medical event(s) that may not be immediately 
life-threatening or result in death or hospitalization but, based upon appropriate medical and 
scientific judgment, may jeopardize the subject or may require intervention [e.g., medical, 
surgical] to prevent one of the other serious outcomes listed in the definition above.) 
Examples of such events include, but are not limited to, intensive treatment in an emergency 
room or at home for allergic bronchospasm; blood dyscrasias or convulsions that do not 
result in hospitalization.)

Although overdose and cancer are not always serious by regulatory definition, these events 
should be reported on an SAE form and sent to BMS in an expedited manner. An overdose is 
defined as the accidental or intentional ingestion or infusion of any dose of a product that is 
considered both excessive and medically important.
NOTE: The following hospitalizations are not considered SAEs in BMS clinical studies:

a visit to the emergency room or other hospital department for less than 24 hours that does 
not result in admission (unless considered an “important medical event” or a life-threatening 
event)

elective surgery, planned before signing consent

admissions as per protocol for a planned medical/surgical procedure

Version date: 08/07/2019
Phase II – ipilimumab/sipuleucel-T
Page 47 of 84

routine health assessment requiring admission for baseline/trending of health status (e.g., 
routine colonoscopy)

medical/surgical admission for purpose other than remedying ill health state and was planned 
prior to entry into the study. Appropriate documentation is required in these cases

admission encountered for another life circumstance that carries no bearing on health status 
and requires no medical/surgical intervention (e.g., lack of housing, economic inadequacy, 
care-giver respite, family circumstances, administrative).
Note that all pregnancies, regardless of outcome, must be reported to the sponsor on a Pregnancy 
Surveillance Form, not an SAE form. All pregnancies must be reported and followed to outcome, 
including pregnancies that occur in the female partner of a male study subject. See Section 7.5.3 
for instructions on reporting pregnancies.
Following the subject’s written consent to participate in the study, all SAEs must be collected, 
including those thought to be associated with protocol-specified procedures. All SAEs must be 
collected that occur within 70 days of discontinuation of dosing of the investigational product. If 
applicable, SAEs must be collected that relate to any later protocol-specified procedure (e.g., a 
follow-up skin biopsy). The investigator should notify BMS and Dendreon of any SAE occurring 
after this time period that is believed to be related to the investigational product or protocol-
specified procedure.
All SAEs whether related or unrelated to the ipilimumab, must be immediately reported to BMS 
and Dendreon (by the investigator or designee) within 24 hours of becoming aware of the event. 
If only limited information is initially available, follow-up reports are required. The original SAE 
form must be kept on file at the study site.  If the SAE occurs at a Participating Institution, the 
Lead Site must also be notified.
If an ongoing SAE changes in its intensity or relationship to the investigational product, a 
follow-up SAE report should be sent immediately to the sponsor. As follow-up information 
becomes available it should be sent immediately using the same procedure used for transmitting 
the initial SAE report. All SAEs should be followed to resolution or stabilization.
7.3.2
Significant Adverse Events
An understanding of the expected toxicities of ipilimumab suggests that the definition of 
“significant adverse events” (SigAEs) should exclude manageable immune related adverse 
events (irAEs). However, IrAEs refractory to steroid treatment will also be considered SigAEs.  
To evaluate the frequency of immune toxicities, patients will be assessed at baseline and monthly 
for immune signs and symptoms. 
Significant Adverse Event (SigAE) is defined by any of the following that are attributable to 
therapy:

Any ≥ grade 3 or 4 non-immune-mediated toxicity (with immune-mediated toxicities 
defined as all irAEs listed in the ipilimumab investigators’ brochure to be considered 
immune and per judgment of the principal investigator for events unknown as immune 
related adverse events).

Version date: 08/07/2019
Phase II – ipilimumab/sipuleucel-T
Page 48 of 84

Any ocular toxicity considered to be immune-mediated and requiring systemic steroids.

Any grade 3 or 4 irAEs that cannot be reduced to grade 2 or below with systemic 
steroids.
The following events are excluded as SigAE:

Any toxicity attributable to androgen deprivation therapy.

Any endocrinopathy thought to be immune-mediated where clinical symptoms are 
controlled with appropriate hormonal replacement therapy.

Hospitalization for ≤ grade 2 events where the reason for hospitalization is to expedite 
evaluation rather than to treat the toxicity.

These criteria apply for both hematologic and non-hematologic toxicities.

Grade 4 laboratory-only abnormalities for uric acid, WBC, and components of the WBC 
count.
7.4
Assignment of Adverse Event Intensity and Relationship to 
Investigational Product
The following categories and definitions of causal relationship to investigational product as 
determined by a physician should be used:

Unrelated: The cause of the AE is known and the event is in no way related to any aspect of 
study participation. If there is any uncertainty regarding AE causality then the event must be 
assessed as possibly related to research participation and reported to the IRB as indicated. 
Often, the cause of an unrelated AE is disease progression.

Possibly Related: An AE is possibly related when there is a reasonable possibility that the 
event might have been caused by study participation. A possibly related event may follow no 
known pattern of response and an alternative cause seems more likely. In other circumstances 
there may be significant uncertainty about the cause of the event, or a possible relationship to 
study participation cannot reasonably be ruled out.

Probably Related: An AE is probably related when there is a reasonable possibility that the 
event is likely to have been caused by study participation. The AE has a timely relationship 
to the study procedure(s) and follows a known pattern of response, but a potential alternative 
cause may be present.

Definitely Related: An AE is definitely related to study participation if it is clear that the 
event was caused by study participation. A definitely related event has a strong temporal 
relationship and an alternative cause is unlikely.
7.5
Collection and Reporting
Adverse events can be spontaneously reported or elicited during open-ended questioning, 
examination, or evaluation of a subject. (In order to prevent reporting bias, subjects should not be 
questioned regarding the specific occurrence of one or more AEs.)

Version date: 08/07/2019
Phase II – ipilimumab/sipuleucel-T
Page 49 of 84
If known, the diagnosis of the underlying illness or disorder should be recorded, rather than its 
individual symptoms. The following information should be captured for all AEs: onset, duration, 
intensity, seriousness, relationship to investigational product, action taken, and treatment 
required. If treatment for the AE was administered, it should be recorded in the medical record.
The investigator shall supply the sponsor and Ethics Committee with any additional requested 
information, notably for reported deaths of subjects.
7.5.1
Handling of Expedited Safety Reports
In accordance with local regulations, BMS and Dendreon will notify investigators of all SAEs 
that are suspected (related to the investigational product) and unexpected (i.e., not previously 
described in the Investigator Brochure). Investigator notification of these events will be in the 
form of an expedited safety report (ESR). 
Other important findings which may be reported by the sponsor as an ESR include: increased 
frequency of a clinically significant expected SAE, an SAE considered associated with study 
procedures that could modify the conduct of the study, lack of efficacy that poses significant 
hazard to study subjects, clinically significant safety finding from a nonclinical (e.g., animal) 
study, important safety recommendations from a study data monitoring committee, or sponsor 
decision to end or temporarily halt a clinical study for safety reasons.
Upon receiving an ESR from BMS, the investigator must review and retain the ESR with the 
Investigator Brochure. Where required by local regulations or when there is a central IRB/IEC 
for the study, the sponsor will submit the ESR to the appropriate IRB/IEC. The investigator and 
IRB/IEC will determine if the informed consent requires revision. The investigator should also 
comply with the IRB/IEC procedures for reporting any other safety information. 
7.5.2
Non-serious Adverse Events
The collection of non-serious AE information should begin at initiation of investigational 
product. If an ongoing non-serious AE worsens in its intensity, or if its relationship to the 
investigational product changes, a new non-serious AE entry for the event should be completed. 
Non-serious AEs should be followed to resolution or stabilization, or reported as SAEs if they 
become serious. Follow-up is also required for non-serious AEs that cause interruption or 
discontinuation of investigational product, or those that are present at the end of study 
participation. Subjects with non-serious AEs at study completion should receive post-treatment 
follow-up as appropriate.
All identified non-serious AEs must be recorded and described in the medical record.
7.5.3
Pregnancy
Study participants must use an effective method of birth control during the course of the study, in 
a manner such that risk of failure is minimized. Before study enrollment, study participants and 
their partners must be advised of the importance of avoiding pregnancy during study 
participation and the potential risk factors for an unintentional pregnancy. The study participant 
must sign an informed consent form documenting this discussion.
Any pregnancy that occurs in a female partner of a male study participant should be reported to 
the sponsors.

7.6
Data Safety Monitoring Plan
Safety assessments will consist of monitoring and recording all adverse events and serious 
adverse events, the regular monitoring of hematology, blood chemistry and urine values, regular 
measurement of vital signs and the performance of physical examinations.
7.6.1
Oversight and Monitoring Plan
The UCSF Helen Diller Family Comprehensive Cancer Center (HDFCCC) Data and Safety 
Monitoring Committee (DSMC) is responsible for monitoring data quality and subject safety for 
all HDFCCC institutional clinical studies.  A summary of DSMC activities for this study include: 

Review of subject data

Review of suspected adverse reactions considered “serious”

Monitoring every six months (depending on study accrual)

Minimum of a yearly regulatory audit
7.6.2
Monitoring and Reporting Guidelines
Investigators will conduct continuous review of data and subject safety and discuss each 
subject’s treatment at monthly Site Committee meetings. These discussions are documented in 
the Site Committee meeting minutes. The discussion will include the number of subjects, 
significant toxicities in accordance with the protocol, and observed responses.
All institutional Phase 2 or 3 studies are designated with a moderate risk assessment. The data is 
monitored twice per year with twenty percent of the subjects monitored (or at least three subjects 
if the calculated value is less than three).  The participating site(s) will submit the source 
documents electronically for the UCSF DSMC to perform remote monitoring and source 
document verification as per the attached Data and Safety Monitoring Plan for Multicenter 
Studies (Phase 2 or 3 Institutional Study) (Appendix 8). 
7.6.3
Review and Oversight Requirements
7.6.3.1
Adverse Event Monitoring
All grade(s) 3-5 adverse events, whether or not unexpected, and whether or not considered to be 
associated with the use of the study drug, will be entered into OnCore®, UCSF’s Clinical Trial 
Management System.
All grade(s) 3-5 adverse events entered into OnCore® will be reviewed on a monthly basis at the 
Site Committee meetings. The Site Committee will review and discuss the selected toxicity, the 
toxicity grade, and the attribution of relationship of the adverse event to the administration of the 
study drug(s).
In addition, all suspected adverse reactions considered “serious” entered into OnCore®, will be 
reviewed and monitored by the Data and Safety Monitoring Committee on an ongoing basis and 
discussed at DSMC meetings, which take place every six weeks.
If a death occurs during the treatment phase of the study or within 30 days after the last 
administration of the study drug(s) and it is determined to be related either to the study drug(s) or 

Version date: 08/07/2019

http://www.research.ucsf.edu/chr/Guide/chrA_AE.asp  
MedWatch forms and information: http://www.fda.gov/medwatch/getforms.htm
Multi-center sites participating in the study will notify the UCSF GU Medical Oncology Clinical 
Research Program 
 of all serious adverse events within 24 hours of 
knowledge of the event. The UCSF clinical research staff will immediately notify the principal 
investigator (PI) or his designee of the SAE. The participating institutions will submit the SAE to 
their own IRB. The participating institution must forward a copy of the report filed with their 
local IRB to the UCSF Urologic Oncology Clinical Research Program within 5 calendar days. 
After the UCSF clinical research staff receives and processes the initial SAE report from the 
participating institution, it will be forwarded to the PI or his designee for review and signature. If 
the SAE is death, and is determined to be possibly, probably or definitely related to the 
investigational drug or any research related procedure, the event must be reported to the DSMC 
Chair or his designee within 24 business hours.  The reporting procedure is by personal 
communication via phone or in person with written documentation of the one-on-one 
communication via e-mail with a copy of the e-mail to the DSMC Administrator.
7.6.4
 Review of Adverse Event Rates
If an increase in the frequency of Grade 3 or 4 adverse events (above the rate reported in the 
Investigator Brochure or package insert) is noted in the study, a report should be submitted to the 
DSMC at the time the increased rate is identified. The report will indicate if the incidence of 
adverse events observed in the study is above the range stated in the Investigator Brochure or 
package insert.
If at any time the Investigator stops enrollment or stops the study due to safety issues, the DSMC 
Chair and DSMC Manager must be notified within 1 business day via e-mail. The DSMC must 
receive a formal letter within 10 business days and the CHR must be notified.

Phase II – ipilimumab/sipuleucel-T
Page 53 of 84
8.1
Identification
Ipilimumab is available in concentrations of 5 mg/mL (50 mg/10 mL and 200 mg/40 mL). The 
sterile solution in the vial is clear and colorless. Ipilimumab is administered via intravenous 
infusion only.
8.2
Packaging and Labeling
BMS will provide ipilimumab at no cost for this study. Ipilimumab will be provided in open-
label containers. The labels will contain the protocol prefix, batch number, content, storage 
conditions, and dispensing instructions along with the Investigational New Drug (IND) caution 
statement.
8.3
Storage, Handling, and Dispensing
8.3.1
Storage
Ipilimumab must be stored in a secure area according to local regulations. The investigator must 
ensure that it is stored at a temperature  2C and  8C.
8.3.2
Handling and Disposal
As with all injectable drugs, care should be taken when handling and preparing ipilimumab. 
Whenever possible, ipilimumab should be prepared in a laminar flow hood or safety cabinet 
using standard precautions for the safe handling of intravenous agents applying aseptic 
technique. Latex gloves are required. If ipilimumab concentrate or solution comes in contact 
with skin or mucosa, immediately and thoroughly wash with soap and water. After final drug 
reconciliation, unused ipilimumab solution should be disposed at the site following procedures 
for the disposal of anticancer drugs.
8.3.3
Dispensing
It is the responsibility of the investigator to ensure that ipilimumab is only dispensed to study 
subjects. The ipilimumab must be dispensed only from official study sites by authorized 
personnel according to local regulations.
8.4
Drug Ordering and Accountability
8.4.1
Initial Orders
Following submission and approval of the required regulatory documents, a supply of 
ipilimumab may be ordered from BMS. Investigators must complete a Drug Request Form and 
email it to: distribution.allentown@thermofisher.com.

STATISTICAL METHODOLOGY
9.1
Sample Size Considerations 
9.1.1
Safety Lead-in
Six patients at the 3 mg/kg dose of ipilimumab will be randomized to Arm 1 and 2, immediate 
versus delayed ipilimumab after 4 doses of SipT. If DLTs are encountered as defined above 
(Section 3.1), then one or both arms may be discontinued. 6 patients will be required to complete 
this phase of the study.
9.1.2
Phase 2
Primary Immune Objective:  This is a multicenter non-comparative randomized Phase 2 trial 
with the primary objective of immunologic efficacy in addition to safety. Immune response is 
defined as an IgG antibody response to either PAP or PA2024 by study week 20. The IgG 
antibody response will be determined with an ELISA assay with a positive response defined as 
titer > 1:400.  To achieve a 40% immune response rate indicating immune activity versus a null 
hypothesis of 15% indicating lack of immune activity assuming a 2-sided type I error of 5% and 
81% power will require 27 total patients per arm. This is based upon the exact binomial test for a 
single sample. The null hypothesis of 15% is based off an observed anti-PAP IgG response rate 
of 17.7% seen at a similar time interval in patients treated with sipuleucel-T in the three phase 3 
clinical trials46.  Therefore, an additional 21 patients beyond the safety lead-in phase will be 
accrued to each arm (an additional 42 patients).  The total number of evaluable patients for the 
Phase 2 study will be 54 patients with accrual up to 66 patients possible.  Patients will be accrued 
at UCSF and MDACC with the randomization to ipilimumab timing stratified by institution.  
Secondary Immune Objectives:  The sample size with 27 patients in each arm is sufficient to 
detect a mean difference between the two study arms in immune modulation, a secondary 
objective, for an effect size (standardized unit) of at least 0.69 for normally distributed variables. 
Similarly, the sample size is sufficient to detect at least a 37% difference between the two 
treatment groups in proportions of patients displaying a specific outcome using Fisher’s exact 
test (e.g. 33% versus 70% achieving a certain change in an immune parameter). For both types of 
tests a level of significance of 0.05 for a directional test and power of at least 0.80 is assumed. 
Directional tests will be performed to test for an effect due to the timing of ipilimumab.  A 
directional test is being used because a greater immune effect is expected with immediate 
administration of ipilimumab.
9.2
Stopping Rules
9.2.1
Stopping Rules for Efficacy
There will be no interim analysis for efficacy due to the small sample size of each treatment arm. 
Although a secondary outcome measure is PSA decline, additional exploratory analyses will be 
performed to investigate the relationship between evidence of immune activation and clinical 
response to aid in designing future investigations.

Version date: 08/07/2019
Phase II – ipilimumab/sipuleucel-T
Page 56 of 84
9.2.2
Stopping Rules for Toxicity
A stopping rule for safety will be applied separately to each arm for the Phase 2 study. Six 
patients on each arm from the safety lead-in study are included in the phase II study and will 
have already been evaluated for safety.  Within each arm, we will stop accrual if there are 3 
SigAEs among the next 10 randomized patients (total accrual per arm would be 16 patients).  
Following these 10 patients, safety would then be assessed cumulatively and accrual will 
continue unless 20% or more of all treated patients on a single arm experience a SigAE as 
defined in section 7.3.2. If this frequency of SigAEs is observed in one arm but not in the other, 
then the arm with the SigAEs will be discontinued while the arm without sigAEs will continue.  
9.3
Methods for Analysis
9.3.1
Primary Endpoints
9.3.1.1
Safety Lead-in: Assess the safety of combining ipilimumab with SipT.
Toxicities will be reported for each study arm at each dose of ipilimumab administered with 
descriptive statistics (e.g. proportions) by tabulating the frequency of the maximum grade 
occurring for each patient for each type using NCI CTC v. 4.0 criteria. As described above the 
type and grade of all such IRAEs will be tabulated by treatment arm. Toxicity results will be 
presented indicating occurrences during the first 20 weeks of protocol therapy and those 
occurring later. 
9.3.1.2
Phase 2: Determine whether the timing of ipilimumab administration impacts PAP 
and PA2024 specific immune responses by SipT
The primary immune study hypothesis to assess the frequency of observing an immune response 
to PAP and/or PA2024 by week 20, when the induction ipilimumab therapy is completed, for 
each of the two ipilimumab schedules will be tested using the single sample binomial exact test. 
The IgM and IgG antibody responses to PAP and PA2024 will be assessed with an ELISA assay 
at baseline and week 20 after the start of sipT treatment (day 113 of study treatment).  A positive 
response will be defined as a titer > 1:400. The primary hypothesis will be tested by comparing 
the proportion of patients achieving an IgG immune response to PAP or PA2024 to the null 
hypothesis of 15% (based off an observed anti-PAP IgG response rate of 17.7% seen at a similar 
time interval in patients treated with sipuleucel-T in the three phase 3 clinical trials46.  using a 
single sample exact test for binary variables as defined above in the sample size justification. The 
same single sample test will be performed for IgM antibodies.  The positive immune proportion 
for both IgG and IgM antibodies to PAP and to PA2024 with 95% confidence intervals will be 
used to summarize the results for each study arm.  No adjustment for multiple comparisons will 
be made.
Exploratory analyses investigating the change in antibody response from baseline to week 20 
when response is considered as a binary variable (positive or negative) will be investigated using 
the Mantel-Haenszel chi square statistic stratified by treatment arm. When the ELISA results are 
treated as continuous variables the change in each immune response will be analyzed using 
analysis of variance (ANOVA) methods.

9.3.2
Secondary Endpoints
9.3.2.1
PSA Decline
Descriptive statistics will be used to characterize the disease and treatment factors for patients 
accrued to each study arm.  The two treatment arms will be compared for comparability of 
baseline disease features and immune parameters using a chi square test for categorical variables, 
a t test for normally distributed continuous variables and the nonparametric Mann-Whitney test 
when the normality assumption cannot be assumed.
Descriptive statistics will be calculated to characterize the proportion of patients achieving a 
PSA decline of at least >30% and >50% and presented along with the 95% confidence intervals 
for each study arm. The maximum overall change in PSA will be summarized by waterfall plots 
for each study arm. Similarly, the proportion of patients achieving an objective response will also 
be determined.  Descriptive statistics will be presented for each study arm to summarize response 
according to important disease features such as LDH (abnormal vs. normal) and prior treatment 
(radiation therapy, RP, systemic steroid usage > 3 months).  Descriptive statistics will be used to 
summarize time to PSA progression.  The Kaplan-Meier product limit will be used to estimate 
the probability of time to PSA progression with durations measured from the start of protocol 
therapy. For each study arm the median time to progression with 95% confidence intervals will 
be presented to summarize clinical efficacy.
9.3.2.2
Radiographic Clinical Responses
For each treatment arm, for patients with objective disease, using immune-related response 
criteria (irRC) criteria, the proportion of patients achieving a complete or partial response will be 
determined and reported with 95% confidence intervals. 
9.3.2.3
Modulation of Effector and Regulatory T Cells
The secondary outcome measures of T cell immune activation will be compared between the two 
treatment arms. Exploratory analyses of antigen-specific T cell responses to PAP and PA2024 
will be measured at weeks 0, 4(study day 1), 7(day 22), 10(day 43), 13 (day 64), 16 (day 85), 20 
(day 113), 32 (day 197) with IFNg ELISPOT. Samples will be obtained just prior to treatment.  
A T cell response to each of the antigens will be defined as >10 spots/300,000. For each antigen 
(PAP and PA2024), the proportion of positive responses by treatment arm at week 20 will be 
calculated and presented with 95% confidence intervals. Agreement in antibody and T cell 
responses will be explored at each time point with McNemar’s test for paired binary data. In 
addition, a test of when a T cell immune response is first recognized will also be identified using 
ANOVA methods when the T cell response is evaluated as a continuous variable. There will not 
be any adjustment for multiple comparisons for these exploratory analyses.
Exploratory ANOVA analyses for mixed models will also be used to compare the magnitude or 
the change from baseline in activated CD4 and CD8 T cells to week 7, 10, 13, 16, and 20 of 
treatment between the two treatment arms. Activation markers to be assessed on CD4 and CD8 T 
cells by flow cytometry will include ICOS/ICOS-L; OX40/OX40-L; 41BB/41BB-L; PD-1/PD-
L1 and PD-L2; CD69, and HLA-DR. Similar comparisons of the magnitude or change from 
baseline in FoxP3+ CD4+ Regulatory T cells at these same time points will be evaluated. 

Version date: 08/07/2019
Phase II – ipilimumab/sipuleucel-T
Page 58 of 84
Additional exploratory analyses again using ANOVA methods will be performed to determine 
whether there is a difference in baseline levels or change by week 14 and 20 in T cell activation 
markers between those achieving a PSA decline of at least 30% or not. 
10 ADMINISTRATIVE SECTION
10.1 Multicenter Communication
The UCSF Coordinating Center provides administration, data management, and organizational 
support for the participating sites in the conduct of a multicenter clinical trial.  The UCSF 
Coordinating Center for Phase II studies will also coordinate, at minimum, monthly conference 
calls with the participating sites at the completion of each cohort or more frequently as needed to 
discuss risk assessment.  The following issues will be discussed as appropriate: 

Enrollment information

Adverse events (i.e. new adverse events and updates on unresolved adverse events and 
new safety information)

Protocol violations

Other issues affecting the conduct of the study

Record Keeping and Record Retention
The Principal Investigator is required to maintain adequate records of the disposition of the drug, 
including dates, quantity, and use by subjects, as well as written records of the disposition of the 
drug when the study ends.  
The Principal Investigator is required to prepare and maintain adequate and accurate case 
histories that record all observations and other data pertinent to the investigation on each 
individual administered the investigational drug or employed as a control in the investigation. 
Case histories include the case report forms and supporting data including, for example, signed 
and dated consent forms and medical records including, for example, progress notes of the 
physician, the individual's hospital chart(s), and the nurses' notes. The case history for each 
individual shall document that informed consent was obtained prior to participation in the study.
Study documentation includes all CRFs, data correction forms or queries, source documents, 
Sponsor-Investigator correspondence, monitoring logs/letters, and regulatory documents (e.g., 
protocol and amendments, IRB correspondence and approval, signed patient consent forms).
Source documents include all recordings of observations or notations of clinical activities and all 
reports and records necessary for the evaluation and reconstruction of the clinical research study.
In accordance with FDA regulations, the investigator shall retain records for a period of 2 years 
following the date a marketing application is approved for the drug for the indication for which it 
is being investigated; or, if no application is to be filed or if the application is not approved for 
such indication, until 2 years after the investigation is discontinued and FDA is notified.
Prior to implementing this protocol at UCSF HDFCCC, the protocol, informed consent form, 
HIPAA authorization and any other information pertaining to participants must be approved by 
the UCSF Committee on Human Research (IRB). Prior to implementing this protocol at the 
participating sites, approval for the UCSF IRB approved protocol must be obtained from the 
participating site’s IRB. 

Version date: 08/07/2019

UCSF will also request that all sub-sites send their Data Safety and Monitoring Plan (DSMP) to 
UCSF for review for approval. If a sub-site does not have its own DSMP in place, UCSF will at 
that time review the resources necessary to include that sub-site and determine whether the 
UCSF study personnel are able to manage the regulatory burden for that sub-site. Upon receipt of 
the required documents, UCSF HDFCCC will formally contact the site and grant permission to 
proceed with enrollment.
 
10.2 Coordinating Center Documentation of Distribution
It is the responsibility of the Study Chair to maintain adequate files documenting the distribution 
of study documents as well as their receipt (when possible). The HDFCCC recommends that the 
Study Chair maintain a correspondence file and log for each segment of distribution (e.g., FDA, 
drug manufacturer, participating sites, etc.).
Correspondence file: should contain copies (paper or electronic) of all protocol versions, cover 
letters, amendment outlines (summary of changes), etc., along with distribution documentation 
and (when available) documentation of receipt.
Correspondence log: should be a brief list of all documents distributed including the date sent, 
recipient(s), and (if available) a tracking number and date received.
At a minimum, the Study Chair must keep documentation of when and to whom the protocol, its 
updates and safety information are distributed.
10.3 Registration
A centralized, 3-part registration procedure will be used. After eligibility screening, patients 
selected to participate will be registered with their study site/institution first, then with the lead 
center and finally in the consortium database (OnCore). 
Institutional Registration
Patient registration at each study site/institution will be conducted according to the institution’s 
established policies. Prior to registration, patients will be asked to sign and date an Institutional 
Review Board (IRB)-approved consent form and a research authorization form/Heath Insurance 
Portability and Accountability Act (HIPAA) authorization form. Patients must be registered with 
the institution before beginning any treatment or study activities.

Version date: 08/07/2019
Phase II – ipilimumab/sipuleucel-T
Page 60 of 84
Lead Center Registration
To initiate lead center registration, study sites/institutions should forward copies of the signed 
informed consent, research authorization/ and HIPAA forms, and the completed and signed 
eligibility checklist to the lead center research coordinator 
. Upon receipt 
of these forms, the lead center will assign a unique patient study identification number, and send 
a confirmation of patient registration to the local coordinator via electronic mail.  A copy of this 
confirmation will be retained by both the lead and local centers. 
A patient cannot be treated until confirmation of enrollment is received.
Consortium Registration
Once registration has been completed at the patient’s institution and with the Lead Center, the 
patient will be registered in the centralized database for the consortium (OnCore). 
10.4 Case Report Forms (CRFs)
The Principal Investigator and/or his/her designee will prepare and maintain adequate and 
accurate participant case histories with observations and data pertinent to the study.  Study 
specific Case Report Forms (CRFs) will document safety and treatment outcomes for safety 
monitoring and data analysis.  All study data will be entered into OnCore® via standardized 
CRFs in accordance with the CTMS study calendar, using single data entry with a secure access 
account.  Site personnel will complete the CRFs as soon as possible upon completion of the 
study visit; the Investigator will review and approve the completed CRFs. 
The information collected on CRFs shall be identical to that appearing in original source 
documents.  
In accordance with federal regulations, the site investigator is responsible for the accuracy and 
authenticity of all clinical and laboratory data entered onto CRFs.  
All source documentation and CTMS data will be available for review/monitoring by the UCSF 
DSMC and regulatory agencies.
10.5 Changes in the Protocol
Once the protocol has been approved by the local IRB, any changes to the protocol must be 
documented in the form of an amendment.  The amendment must be signed by the Investigator 
and approved by the local IRB prior to implementation.  
If it becomes necessary to alter the protocol to eliminate an immediate hazard to patients, an 
amendment may be implemented prior to IRB approval.  In this circumstance, however, the 
Investigator must then notify the IRB in writing within five (5) working days after 
implementation.  The Study Chair and the UCSF study team will be responsible for updating any 
participating sites.
10.6 Informed Consent
All participants must be provided a consent form describing the study with sufficient information 
for each participant to make an informed decision regarding their participation.  Participants 
must sign the site IRB-approved informed consent form prior to participation in any study 
specific procedure.  The participant must receive 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.

including dates, quantity, and use by subjects, as well as written records of the disposition of the 
drug when the study ends.  
The Principal Investigator is required to prepare and maintain adequate and accurate case 
histories that record all observations and other data pertinent to the investigation on each 
individual administered the investigational drug or employed as a control in the investigation. 
Case histories include the case report forms and supporting data (e.g., signed and dated consent 
forms and medical records, such as progress notes of the physician, the individual's hospital 
chart(s), and the nurses' notes. The case history for each individual shall document that informed 
consent was obtained prior to participation in the study.
Study documentation includes all CRFs, data correction forms or queries, source documents, 
Study Chair correspondence, monitoring logs/letters, and regulatory documents (e.g., protocol 
and amendments, IRB correspondence and approval, signed patient consent forms).
Source documents include all recordings of observations or notations of clinical activities and all 
reports and records necessary for the evaluation and reconstruction of the clinical research study.
In accordance with FDA regulations, the site investigator shall retain records for a period of 2 
years following the date a marketing application is approved for the drug for the indication for 
which it is being investigated; or, if no application is to be filed or if the application is not 
approved for such indication, until 2 years after the investigation is discontinued and FDA is 
notified.
10.8 Good Clinical Practice
This study will be conducted in accordance with Good Clinical Practice (GCP), as defined by the 
International Conference on Harmonisation (ICH) and in accordance with the ethical principles 
underlying European Union Directive 2001/20/EC and the United States Code of Federal 
Regulations, Title 21, Part 50 (21CFR50).
The study will be conducted in compliance with the protocol. The protocol and any amendments 
and the subject informed consent will receive Institutional Review Board/Independent Ethics 
Committee (IRB/IEC) approval/favorable opinion prior to initiation of the study.
All potential serious breaches must be reported to BMS immediately. A serious breach is a 
breach of the conditions and principles of GCP in connection with the study or the protocol, 
which is likely to affect, to a significant degree, the safety or physical or mental integrity of the 
subjects of the study or the scientific value of the study.
Study personnel involved in conducting this study will be qualified by education, training, and 
experience to perform their respective task(s). This study will not use the services of study 
personnel where sanctions have been invoked or where there has been scientific misconduct or

10.9 Protection of Human Subjects
Protection from Unnecessary Harm 
Each clinical site is responsible for protecting all subjects involved in human experimentation. 
This is accomplished through the IRB mechanism and the process of informed consent. The IRB 
reviews all proposed studies involving human experimentation and ensures that the subject’s 
rights and welfare are protected and that the potential benefits and/or the importance of the 
knowledge to be gained outweigh the risks to the individual. The IRB also reviews the informed 
consent document associated with each study in order to ensure that the consent document 
accurately and clearly communicates the nature of the research to be done and its associated risks 
and benefits. 
Protection of Privacy 
Patients will be informed of the extent to which their confidential health information generated 
from this study may be used for research purposes. Following this discussion, they will be asked 
to sign the HIPAA form and informed consent documents. The original signed document will 
become part of the patient’s medical records, and each patient will receive a copy of the signed 
document. The use and disclosure of protected health information will be limited to the 
individuals described in the informed consent document.
10.10 Pre-study Documentation 
This study will be conducted in accordance with the ethical principles that have their origin in 
the Declaration of Helsinki as stated in 21 CFR §312.120(c)(4); consistent with GCP and all 
applicable regulatory requirements.
Before initiating this trial, each site Investigator will have written and dated approval from the 
Institutional Review Board for the protocol, written informed consent form, subject recruitment 
materials, and any other written information to be provided to subjects before any protocol 
related procedures are performed on any subjects.  
The clinical investigation will not begin until the FDA has determined that the study under the 
Investigational Drug Application (IND) is allowed to proceed. 
Each site investigator must comply with the applicable regulations in Title 21 of the Code of 
Federal Regulations (21 CFR §50, §54, and §312), GCP/ICH guidelines, and all applicable 
regulatory requirements.  The local IRBs must comply with the regulations in 21 CFR §56 and 
applicable regulatory requirements.
10.11 Institutional Review Board/Independent Ethics Committee (IRB/IEC)
The protocol, the proposed informed consent form, and all forms of participant information 
related to the study (e.g., advertisements used to recruit participants) will be reviewed and 
approved by each site’s local Institutional Review Board. The initial protocol and all protocol 
amendments must be approved by each site’s local IRB prior to implementation.

APPENDIX 9: Multicenter Institutional Studies
Data and Safety Monitoring Plan for Multicenter Study (Phase 2 or 3 Institutional Study)
The UCSF Helen Diller Family Comprehensive Cancer Center (HDFCCC) Data and Safety 
Monitoring Committee (DSMC) is responsible for monitoring data quality and subject safety for 
all HDFCCC institutional clinical studies.  A summary of DSMC activities for this study include: 

Review of subject data

Review of suspected adverse reactions considered “serious”

Monitoring every six months (depending on study accrual)

Minimum of a yearly regulatory audit
Monitoring and Reporting Guidelines
All institutional Phase 2 or 3 therapeutic studies are designated with a moderate risk assessment. 
The data is monitored every six months, with twenty percent of the subjects monitored (or at 
least three subjects if the calculated value is less than three). 
The UCSF Coordinating Center provides administration, data management, and organizational 
support for the participating sites in the conduct of a multicenter clinical trial. The UCSF 
Coordinating Center will also coordinate quarterly conference calls with the participating sites to 
communicate the review of adverse events, safety data, and other study matters. 
The Principal Investigator at the UCSF Coordinating Center will hold the role of Study Chair. 
The Study Chair is responsible for the overall conduct of the study and for monitoring its safety 
and progress at all participating sites. The Study Chair will conduct continuous review of data 
and subject safety and discuss each subject’s treatment at monthly UCSF Site Committee 
meetings. The discussions are documented in the UCSF Site Committee meeting minutes. 
Multicenter communication 
The UCSF Coordinating Center provides administration, data management, and organizational 
support for the participating sites in the conduct of a multicenter clinical trial. The UCSF 
Coordinating Center will also coordinate, at minimum, quarterly conference calls with the 
participating sites or more frequently as needed to discuss risk assessment. The following issues 
will be discussed as appropriate:

Enrollment information

Adverse Events (i.e. new adverse events and updates on unresolved adverse events and 
new safety information) 

Protocol Violations 

Other issues affecting the conduct of the study 
Adverse events reporting to the DSMC will include reports from both the UCSF Coordinating 
Center, as well as the participating sites. The DSMC will be responsible for monitoring all data 
entered in OnCore® at the UCSF Coordinating Center and the participating sites. The data (i.e., 
copies of source documents) from the participating sites will be sent electronically to the UCSF 
Coordinating Center prior to the monitoring visits in order for the DSMC to remotely monitor 
the participating site’s compliance with the protocol, patient safety, and to verify data entry.

Version date: 08/07/2019
Phase II – ipilimumab/sipuleucel-T
Page 78 of 84
Adverse Event Review and Monitoring
All grade(s) 3-5 adverse events, whether or not unexpected, and whether or not considered to be 
associated with the use of the study drug, will be entered into OnCore®, UCSF’s Clinical Trial 
Management System.
All Grade 3-5 adverse events entered into OnCore® will be reviewed on a monthly basis at the 
UCSF Site Committee meetings. All clinically significant adverse events must be reported to the 
UCSF Coordinating Center by the participating sites within 10 business days of becoming aware 
of the event or during the next scheduled quarterly conference call, whichever is sooner. The 
UCSF Site Committee will review and discuss the selected toxicity, the toxicity grade, and the 
attribution of relationship of the adverse event to the administration of the study drug(s) from the 
UCSF Coordinating Center and the participating sites. 
In addition, all suspected adverse reactions considered “serious” must be entered in OnCore® 
and reported to the UCSF Coordinating Center within 1 business day. The suspected adverse 
reactions considered “serious” will be reviewed and monitored by the Data and Safety 
Monitoring Committee on an ongoing basis and discussed at the DSMC meeting, which take 
place every six (6) weeks. 
If a death occurs during the treatment phase of the study or within 30 days after the last 
administration of the study drug(s) and is determined to be related either to the investigational 
drug or any research related procedure, the Study Chair at the UCSF Coordinating Center or the 
assigned designee must be notified within 1 business day from the participating site(s) and the 
Study Chair must then notify the DSMC Chair or qualified alternate within 1 business day of this 
notification. The contact may be by phone or e-mail. 
Increase in Adverse Event Rates
If an increase in the frequency of Grade 3 or 4 adverse events (above the rate reported in the 
Investigator Brochure or package insert) is noted in the study, the Study Chair at the UCSF 
Coordinating Center is responsible for notifying the DSMC at the time the increased rate is 
identified. The report will indicate if the incidence of adverse events observed in the study is 
above the range stated in the Investigator Brochure or package insert. 
If at any time the Study Chair stops enrollment or stops the study due to safety issues, the DSMC 
Chair and DSMC Manager must be notified within 1 business day via e-mail. The DSMC must 
receive a formal letter within 10 business days and the IRB must be notified.

APPENDIX 10: UCSF Policy/Procedure for Required Regulatory 
Documents for UCSF Investigator-Initiated Oncology Clinical Trials 
with an Investigator held Investigational New Drug (IND)
Purpose
This policy defines the required Regulatory Documents for Single Site and Multicenter 
Investigator Initiated Oncology Clinical Trials at the Helen Diller Family Comprehensive Cancer 
Center (HDFCCC) where the Principal Investigator (PI) holds the IND.
Background
The International Conference on Harmonization (ICH) Good Clinical Practices (GCP) 
Guidelines define Essential Regulatory Documents as those documents which individually and 
collectively permit evaluation of the conduct of a trial and the quality of data produced. These 
documents serve to demonstrate compliance with standards of GCP and with all applicable 
regulatory requirements. Filing essential documents in a timely manner can greatly assist in the 
successful management of a clinical trial.
The Regulatory Documents will consist of electronic files in both iMedRIS and OnCore®, as 
well as paper files in the Regulatory Binders for both the Coordinating Site and the Participating 
Site(s) in the HDFCCC Investigator Initiated Oncology Clinical Trials.
