Introduction- Background and Rationale 
1.1 
Bladder Cancer – Disease Overview 
Bladder cancer (BC) is the 6th most common malignancy in the United States (US) with an 
estimated 79,030 new cases and 16,870 deaths in 2017.1 It is the 4th most common cancer 
in men and there are presently >500,000 BC patients alive in the US. It accounts for about 
5% of all new cancers in the US. It is also the most expensive cancer to treat from diagnosis 
to death. Almost a third of BC patients present with muscle-invasive bladder cancer (MIBC). 
Moreover, among the ~65% of BC patients presenting with non-muscle-invasive bladder 
cancer (NMIBC), up to 15-20% may progress to MIBC every year. Altogether, approximately 
35,000 patients are diagnosed with MIBC in the US annually.2 Urothelial carcinoma (UC) is 
the most common BC histology and can affect the entire urinary tract (e.g. renal pelvis, 
ureter, proximal urethra). Radical cystectomy (RC) is the standard of care for MIBC, 
however it results in a 5-year recurrence-free survival rate of 68% (only 35% for those with 
lymph node involvement). This is most probably due to micro-metastases present at the 
time of surgery considering the high rate of distant recurrence.3,4 Systemic cisplatin-based 
combination chemotherapy prior to RC results in high pathologic complete response rates 
and modest but clinically meaningful increase in overall survival compared to local therapy 
alone, and has become the standard of care for cisplatin-eligible patients with MIBC.5-7 
1.2 
Background 
Patients with UC often have multiple medical comorbidities which preclude cisplatin use.8 A 
reported consensus definition of cisplatin ineligibility for patients with metastatic UC includes 
any of the following clinical characteristics: ECOG performance status ≥ 2, creatinine 
clearance <60 mL/min, grade ≥ 2 hearing loss, grade ≥ 2 neuropathy, and/or New York 
Heart Association (NYHA) Class ≥ III heart failure. The proportion of patients ineligible for 
cisplatin based on renal function alone has been reported up to 50%, and if other factors 
are also considered the proportion is probably even higher.9 Furthermore, among patients 
with MIBC who do not receive cisplatin-based chemotherapy, a recent analysis from the 
National Cancer Database (NCDB) recorded patient refusal of cisplatin-based 
chemotherapy in 58% of patients as the reason for its omission.10 Several non-cisplatin-
based chemotherapy regimens and targeted agents have been evaluated in cisplatin-
ineligible patients with UC, but none has demonstrated adequate efficacy to warrant wide 
adoption or regulatory approval. Before the recent Food and Drug Administration (FDA) 
approval of atezolizumab and nivolumab, there had been no advances in the systemic 
therapy of UC for almost three decades, resulting in considerable attention and prioritization 
from regulatory agencies. Therefore, cisplatin-ineligible patients represent a large 
population “in need” of effective therapies. In addition, due to the very high number of 
cisplatin-ineligible patients and the opportunity to examine both pre- and post-therapy tumor 
tissue and blood for pharmacodynamics and biomarker assessment, the neoadjuvant (pre-
RC) setting presents an ideal opportunity to evaluate novel therapeutic agents that can be 
applied in other cancer types and settings. 
1.3 
Rationale for Immunotherapy 
The role of immunotherapy in UC is very well established. Intra-vesical administration of 
Bacillus Calmette-Guerin (BCG), a bovine mycoplasma-derived agent that lowers bladder 
tumor recurrence by inciting a robust immunologic reaction in the bladder 
microenvironment, is standard of care for high grade NMIBC. The evident clinical benefit 
with intra-vesical BCG immunotherapy supports the potential benefit from systemic 
immunotherapies in UC. The presence of CD8 tumor-infiltrating lymphocytes (TILs) has 
been associated with longer disease-free and overall survival in UC.11,12 Aberrant 
expression of the immune checkpoint programmed death-ligand 1 (PD-L1) has been shown 
in UC, implying that tumor-associated PD-L1 can play a regulatory role in anti-tumor 
immunity and be a relevant therapeutic target.13 PD-L1 expression was associated with high

13 
tumor grade, tumor infiltration by mononuclear cells, stage progression and attenuated 
response to BCG immunotherapy by neutralizing T cells.14 In NMIBC, PD-L1 expression 
was observed in 69% of post-BCG relapsed tumors compared to 19% of BCG-naïve tumors 
from the same patients implicating programmed death-1 (PD-1)/PD-L1 pathway as a 
possible resistance mechanism to BCG therapy.14 Furthermore, the number of TILs and 
CD8+ peripheral blood lymphocytes have been found to be reversely correlated with each 
other; while each has been associated with recurrence in UC.15,16 Therefore, 
immunotherapy via inhibition of PD-1/PD-L1 mediated pathway can be an important tool to 
improve outcomes in UC. 
1.4 
Rationale for Nivolumab Therapy in MIBC Patients 
Breakthrough clinical data have been noted with agents targeting cytotoxic T-programmed 
death-1 (PD-1) and PD-L1.17,18 PD-1 expression in TILs has been observed in almost all 
MIBC patients undergoing cystectomy with nearly all TILs expressing CD8; 76% of patients 
with PD-L1 positive tumors had moderate or marked TILs PD-1 expression. PD-L1 
expression in bladder tumors and TILs PD-1 expression were significantly associated with 
advanced pathologic stage, and PD-L1 expression independently predicted all-cause 
mortality after cystectomy.19 In a Phase I expanded cohort of post-platinum advanced UC, 
anti-PD-L1 single agent therapy induced up to 67% objective response rate in tumors with 
high PD-L1 immunostaining, including rapid and durable responses with an excellent safety 
profile.20,21 A Phase II trial with single agent anti-PDL1 confirmed durable activity and good 
tolerability in this patient population; the level of PD-L1 expression on immune cells, The 
Cancer Genome Atlas (TCGA) subtype and mutational load correlated with response.22 
Significant anti-tumor activity and favorable tolerability was also noted with the anti-PD1 
agents, pembrolizumab and nivolumab in post-platinum advanced UC.18,23-25 Similar data 
have been noted with two other anti-PD-L1 agents, durvalumab and avelumab.26,27 
Pembrolizumab demonstrated overall survival benefit over chemotherapy in a large Phase 
III trial of post-platinum metastatic & locally-advanced UC.24 Pembrolizumab and 
atezolizumab have also shown significant efficacy as frontline therapy in cisplatin-ineligible 
patients with advanced UC with a good safety profile.28,29 Atezolizumab, nivolumab, 
durvalumab 
and 
avelumab 
have 
been 
FDA-approved 
for 
platinum-treated 
advanced/metastatic UC. 
A flat dose of nivolumab 240 mg Q2W is identical to a dose of 3 mg/kg for subjects 
weighing 80 kg, the observed median body weight in nivolumab treated cancer patients.30 
The FDA has approved nivolumab for metastatic urothelial carcinoma at a dose of 240 mg 
every 2 weeks. 
However, Nivolumab 480 mg Q4W allows flexibility of dosing with less frequent visits.30 
Population pharmacokinetics (PKs) and exposure response analysis have been performed 
and support the use of 480 mg Q4W.30 Nivolumab has been shown to be safe and well 
tolerated up to a dose level of 10 mg/kg, and the relationship between nivolumab 
exposure produced by 3 mg/kg and efficacy and safety has been found to be relatively 
flat.30 
Two neoadjuvant doses of nivolumab 480 mg Q4W for 2 doses (week 0 and 4) should show 
efficacy as well as provide immunologic effects and allow radical cystectomy completion 
within 6 weeks of last dose of neoadjuvant therapy.

Lirilumab dose and schedule was based on a Bristol-Myers Squibb (BMS) Phase I 
safety study. Two neoadjuvant doses of lirilumab (week 0 and 4) should show 
efficacy as well as provide immunologic effects and allow radical cystectomy 
completion within 6 weeks of last dose of neoadjuvant therapy. 
Refer to the Lirilumab IB for details regarding lirilumab. 
1.6 
Rationale for Dual Immunotherapy in UC 
Despite very promising, rapid and durable anti-tumor responses with single agent immune 
checkpoint inhibitor therapy, the overall response rates with anti-PD-1/PD-L1 agents alone 
is low, especially in tumors with low PD-L1 protein expression. To augment the efficacy of 
immune checkpoint inhibitors, various immunotherapy combination strategies are being 
investigated. Phase I trial of combination nivolumab and lirilumab in solid tumors has been 
conducted.38 An interim analysis from a Phase I/II trial of nivolumab/lirilumab combination 
in advanced platinum refractory squamous cell head and neck carcinoma was presented 
recently.39 Among 29 evaluable patients, the objective response rate was 24%. Five patients 
had deep responses with reductions in tumor burden >80%. Early signal of enhanced 
clinical benefit was noted in PD-L1-positive tumors, with an objective response rate of 41% 
in patients with >1% PD-L1 expression. The safety profile of the combination was generally 
consistent with that observed with nivolumab alone. The overall treatment-related adverse 
event rate was 72% (114/159) and the grade 3-4 treatment-related adverse event rate was 
15% (24/159). Discontinuations due to treatment-related adverse events occurred in 8% of 
patients (12/159). In a recent press release on 11/22/2017, the combination of nivolumab 
and lirilumab did not show any apparent benefit in an expanded cohort of patients with 
squamous cell head and neck carcinoma; however, this tumor type is different than UC 
while there was no new toxicity concern.40 The combination regimen of anti-PD-1 and anti-
KIR agents are feasible and very attractive based on their complementary and non-
overlapping roles in regulating both adaptive and innate immune response as well as 
impacting both CD8+ T-cells and NK-cells. Data suggests that T and NK cell activation in 
bladder cancer models requires the collaboration of various immune cells, suggesting that 
combination immunotherapies may have at least additive value.41,42 Moreover, regulation of 
T cell responses by innate lymphoid cells is clearly documented. Direct and indirect 
crosstalk between innate cells and T cells during and after T cell activation can impact their 
differentiation, polarization, and survival; this synergistic activity may translate to improved 
outcomes.43,44 The neoadjuvant setting provides an optimal platform to evaluate the safety 
and efficacy of this combination, leveraging the ability to evaluate tissue, urine and blood-
based biomarkers before, during and after combination therapy. Of particular interest is the 
density of CD8+ TILs following treatment, which can be used as a surrogate for better 
survival and prognosis in UC. Data from this neoadjuvant trial can inform further 
development of this combination in many UC settings as well as in other cancer types. 
1.7 
Background and Rationale of Key Secondary Endpoint 
Density of CD8+ TILs has been found to correlate with survival outcomes in UC. An older 
study assessed the prognostic value of TILs in a cohort of 512 patients with UC over a 
period of 9 years.11 In advanced stage tumors (T3-T4) increased TIL density was related to 
less aggressive behavior whereas in a multivariate analysis, dense TILs were a highly 
significant factor of favorable prognosis and allowed to separate UC into prognostic groups 
based on TIL density.11 A study by Sharma et al. in 2007 included a cohort of 69 patients 
with UC who underwent cystectomy. Patients were separated into those with high vs low 
density of TILs in cystectomy samples. Patients with advanced UC (pT2, pT3 and pT4) who 
had increased density of TILs were shown to have better disease-free survival and overall 
survival, compared to patients at the same stage who had lower density of TILs.12 A study 
by Faraj et al. also looked at 56 tissue microarrays from cystectomy samples in a single 
institution. Patient samples were divided into high and low CD8+ T cell density categories.

High CD8+ T cell density was associated with longer overall and disease-specific survival 
even when adjusted for demographic and clinicopathologic parameters.42 Another study 
showed that CD8+ to Treg TIL density in the pre-treatment tissues predicted response to 
neoadjuvant chemotherapy.45 Altogether, data suggests that CD8+ TIL density is associated 
with improved outcomes in advanced stage MIBC and can be utilized as a surrogate marker 
of clinical benefit. This data needs to be verified prospectively and this can be done as part 
of a feasibility trial suggested here. 
1.8 
Rationale for Phase Ib Trial of Nivolumab/Lirilumab Combination vs Nivolumab Alone as 
Neoadjuvant Therapy in Cisplatin-Ineligible Patients with MIBC or those Refusing Cisplatin-
Based Chemotherapy 
As detailed above, a strong rationale exists to study both nivolumab and lirilumab in 
cisplatin-ineligible MIBC in the neoadjuvant setting based upon the following: 
1. Cisplatin-ineligible or cisplatin-refusing patients with MIBC represents a common, 
sizeable population. 
2. Expression of PD-1/PD-L1 is frequent in MIBC. 
3. NK-cell function and number have been associated with improved outcomes in NMIBC 
and MIBC. 
4. Cisplatin-ineligible or cisplatin-refusing patients with MIBC represents a potential 
nivolumab/lirilumab FDA-registration pathway population with few competing regimens 
in this space. 
The Phase Ib design in the neoadjuvant setting provides several additional advantages 
including: 
1. Assessment of safety and feasibility of nivolumab alone and nivolumab/lirilumab in a 
curative disease setting (neoadjuvant). 
2. An ideal platform for biomarker discovery and validation efforts due to the ability to 
analyze pre- and post-treatment bio-specimens. 
3. Preliminary assessment of whether single-agent immunotherapy (nivolumab alone) and 
combination immunotherapy (nivolumab/lirilumab) have efficacy in the neoadjuvant 
setting. 
As such, the cisplatin-ineligible MIBC population presents a unique opportunity to assess 
pre- and post-treatment pharmacodynamic effects and gain preliminary safety and efficacy 
data to inform further development strategy decisions for both nivolumab without or with 
lirilumab in the neoadjuvant setting in muscle-invasive bladder cancer.

NOTE: PrECOG does not allow waivers to any protocol specified criteria. All eligibility criteria listed 
in Section 3 must be met, without exception. The registration of individuals who do not meet 
all criteria listed in Section 3 can result in the participant being censored from the analysis 
of the study, and a major protocol violation. All questions regarding clarification of eligibility 
criteria must be directed to the Medical Monitor or PrECOG Study Contact. 
NOTE: Institutions may use the eligibility checklist as source documentation if it has been reviewed, 
signed, and dated prior to registration by the treating physician. 
3.1 
Patients must have histologically confirmed MIBC (T2-T4a, N0-N1, M0 per American Joint 
Commission on Cancer [AJCC]) pure or mixed histology urothelial carcinoma [urothelial

requirements and International Conference on Harmonization/Good Clinical Practice 
(ICH/GCP). 
The study will be conducted in compliance with the protocol. The protocol and any 
amendments and the patient informed consent will receive Institutional Review Board (IRB) 
approval prior to initiation of the study. 
Freely given written informed consent must be obtained from every patient or their legally 
authorized representative prior to clinical trial participation, including informed consent for 
any screening procedures conducted to establish patient eligibility for the trial. 
Study personnel involved in conducting this trial will be qualified by education, training, and 
experience to perform their respective task(s). This trial will not use the services of 
investigators or study personnel where sanctions have been invoked or where there has 
been scientific misconduct or fraud (e.g., loss of medical licensure, debarment). 
Investigators are responsible for the conduct of the study at their study site. 
4.2 
Regulatory Requirements 
Before a site may enter patients, protocol-specific regulatory and other documents must be 
submitted to PrECOG as noted in study materials. Detailed information regarding document 
submission and control is provided to each site in separate study materials. 
Once required documents are received, reviewed, and approved by PrECOG or their 
representative, a Study Reference Manual (SRM) will be forwarded to the site. Any changes 
to site regulatory documents must be submitted by the investigator to the responsible party 
in a timely manner. Initial study drug shipment will not occur until the regulatory packet is 
complete. No patients will begin protocol therapy without formal registration as per the 
process below. 
4.3 
Phase Ib Patient Registration 
Patients must not start protocol treatment prior to registration. 
Patients must meet all of the eligibility requirements listed in Section 3 prior to registration. 
An eligibility checklist is included in Section 3. A confirmation of eligibility assessment by 
the investigator and/or site will be performed during the registration process. 
Upon determination that a subject meets eligibility criteria, the subject will be registered in 
the study by site personnel via an electronic data capture (eDC) system. 
NOTE: The local site pathologist will be asked to estimate and record the rough 
approximate percentage of viable tumor in the TURBT sample (initial or repeat TURBT 
with highest tumor content) to document at least 20% viable tumor content prior to 
registration. This is to ensure adequate tissue is available to perform tumor 
infiltrating CD8+ T-cell assessment. (The actual CD8+ T-analysis will be done by a 
Central Laboratory and will not be done prior to registration.) 
Neoadjuvant treatment should begin ≤ 10 working days from date of registration. Please 
note neoadjuvant treatment must also start within 10 weeks of the most recent TURBT that 
showed muscularis propria invasion.

Study Design 
This is a Phase Ib open-label clinical trial for patients that are either cisplatin-ineligible or refuse 
cisplatin-based chemotherapy and have MIBC (T2-T4a, N0-N1, M0). Patients will be sequentially 
enrolled first into Cohort 1 treated with nivolumab alone (N=12). In the absence of the occurrence 
of high rate of treatment related AEs as defined in Section 5.4 and 13.1.1 with neoadjuvant 
nivolumab treatment, the study will proceed with enrollment into Cohort 2 of neoadjuvant treatment 
with combination nivolumab/lirilumab. (In both cohorts, neoadjuvant treatment must start within 10 
weeks of transurethral resection of the most recent TURBT that showed muscularis propria 
invasion). Each group will receive a total of 4 weeks (week 0 and 4) of neoadjuvant therapy followed 
by radical cystectomy (RC) with bilateral (standard or extended) pelvic lymph node dissection 
(PLND). 
The RC with bilateral (standard or extended) PLND will occur as soon as possible but within 6 weeks 
after the last neoadjuvant dose in either cohort. 
5.1 
Number of Patients 
The study will aim to screen 43 eligible patients in order to enroll 36 patients in the trial 
(assuming about 20% tumor tissue assessment screen failure rate). Estimate at least 2-3 
patients per month at approximately 8 sites. The estimated time for accrual completion will 
be approximately 18 months. 
5.2 
Replacement of Patients 
A patient will be replaced if following TURBT and registration into the study, they do not 
meet any of the following criteria: 
• 
Begin neoadjuvant therapy within 10 weeks of the most recent TURBT that showed 
muscularis propria invasion 
• 
Receive at least one study treatment dose (nivolumab alone or nivolumab and 
lirilumab) 
• 
Adequate (at least 20%) viable tumor content in any TURBT 
5.3 
Expected Duration of Treatment and Patient Participation 
Following registration, patients in each group will receive a total of 4 weeks of neoadjuvant 
therapy followed by RC with bilateral (standard or extended) PLND as soon as possible but 
within 6 weeks of the completion of neoadjuvant therapy. 
Off treatment visit will occur approximately 30 days following cystectomy (if cystectomy is 
not performed, Off Treatment visit should be performed at next scheduled appointment or 
treating physician discretion, as clinically indicated) and patients will be followed for 100 
days after neoadjuvant treatment for AEs. Adverse events may be reviewed at the next visit 
≥ 100 days after last dose of neoadjuvant therapy or phone follow-up may be done to review 
adverse events. 
Patients will be followed clinically and radiographically for at least 2 years post-cystectomy 
or when study-wide follow-up ends per standard of care. Date of diagnosis for progression, 
first subsequent therapy and survival shall be reported. Phone follow-up may also be done 
for patients unable or unwilling to return for follow-up evaluations. 
5.4 
Interim Safety Analysis 
After 6 and 12 patients on Cohort 1 and 6 patients on Cohort 2 complete surgery, the study 
will be monitored for nivolumab or nivolumab/lirilumab treatment-related toxicities as noted 
below. 
• 
Any Grade hypophysitis, meningitis, or immune-related neurologic AEs

• 
Grade 2 or higher myocarditis 
• 
Persistent Grade 2 immunologic AEs (such as colitis, pneumonitis, and nephritis) that 
do not recover to Grade 1 or resolve within 6 weeks after the last dose of study drug 
(Exceptions: rash, fatigue, amylase/lipase elevations, other electrolyte abnormalities). 
• 
Grade 3 or higher immunologic AEs such as uveitis, pericarditis, hepatitis, 
colitis/diarrhea, nephritis, pancreatitis, myositis, endocrine, rash, etc., except Grade 3 
hypothyroidism or Grade 3 infusion reaction. 
• 
Grade 4 non immunologic AEs, as well as Grade 4 hypothyroidism or Grade 4 infusion 
reaction. 
There will be no suspension to accrual after the first 6 patients in each cohort. Also, accrual 
will start on Cohort 2 once accrual to Cohort 1 is complete (unless needed based on toxicity 
noted). 
If 3 or more of these 6 patients on a single cohort experience nivolumab or nivolumab/ 
lirilumab treatment-related adverse events as noted above, the study will be suspended for 
a safety review.

Treatment Plan 
6.1 
Overview 
No investigational or commercial agents or therapies other than those described below may 
be administered with the intent to treat the subject's malignancy. 
Neoadjuvant treatment must start within 10 weeks of transurethral resection of the most 
recent bladder tumor (TURBT) that showed muscularis propria invasion. 
Patients enrolled in the trial will be administered one of two of the following treatment 
regimens: 
Cohort 1: Nivolumab 480 mg IV over approximately 30 minutes every 4 weeks for 2 neo-
adjuvant doses (week 0 and 4) followed by radical cystectomy (RC) with bilateral (standard 
or extended) pelvic lymph node dissection (PLND) as soon as possible but within 6 weeks 
after the last neoadjuvant infusion. 
Cohort 2: Nivolumab 480 mg intravenously (IV) over approximately 60 minutes every 4 
weeks for 2 neo-adjuvant doses (week 0 and 4) with at least a 30 minute rest between 
infusions followed by lirilumab 240 mg IV over approximately 60 minutes every 4 weeks for 
2 neo-adjuvant doses (week 0 and 4) followed by RC with bilateral (standard or extended) 
PLND as soon as possible but within 6 weeks after the last neoadjuvant infusion. 
NOTE: A few mild infusion reactions occurred on Cohort 2 with the nivolumab infusion, 
requiring only steroids and resuming dose at 50%. Infusion time increased to 60 minutes 
per package insert guidelines. 
6.1.1 
Nivolumab Administration 
Cohort 1 
Neoadjuvant Dose: Subjects will receive nivolumab 480 mg IV over approximately 
30 minutes for a total of 2 doses on week 0 and 4. 
Nivolumab is to be administered as an approximately 30 minute IV infusion, using 
a volumetric pump with a 0.2/0.22 micron in-line filter. It is not to be administered 
as an IV push or bolus injection. Nivolumab infusion will be followed by at least a 
30 minute rest before lirilumab infusion is given. 
Cohort 2 
Neoadjuvant Dose: Subjects will receive nivolumab 480 mg IV over approximately 
60 minutes for a total of 2 doses on week 0 and 4. 
Nivolumab is to be administered as an approximately 60 minute IV infusion, using 
a volumetric pump with a 0.2/0.22 micron in-line filter. It is not to be administered 
as an IV push or bolus injection. Nivolumab infusion will be followed by at least a 
30 minute rest before lirilumab infusion is given. 
Refer to Section 12 for further handling and stability information. 
6.1.2 
Lirilumab Administration 
Cohort 1 
Subjects will not receive lirilumab. 
Cohort 2

Dose Delays 
All toxicities should be graded according to the National Cancer Institute (NCI) Common 
Terminology Criteria for Adverse Events Version 5.0 (CTCAE V5.0). A copy of the CTCAE 
V5.0 can be downloaded from the CTEP website (http://www.ctep.cancer.gov). 
A +/-3 day window is allowed for scheduled therapy, required tests and/or visits except as otherwise 
noted. Delays due to holidays, weekends, bad weather or other unforeseen circumstances will be 
permitted. 
Dose delays are not required for adverse events not deemed to be related to study treatment (i.e. 
events due to underlying disease) or for laboratory abnormalities not deemed to be clinically 
significant. Treat accordingly per institutional standards. 
Any patient who cannot receive study therapy within 6 weeks from the previous dose in either cohort, 
will be permanently discontinued, except as noted below. 
NO dose modifications will be allowed. 
7.1 
Dose Delays for Treatment Related Hematological Toxicity 
7.1.1 
Grade 1 and Grade 2 Toxicities 
No dose interruptions will be performed for Grade 1 or 2 hematologic toxicities. 
7.1.2 
Grade 3 Toxicities 
Study therapy will be permanently discontinued for Grade 3 drug-related 
thrombocytopenia >7 days or associated with bleeding. 
If the patient experiences other Grade 3 treatment related hematologic toxicity in 
either study cohort, all study therapy must be withheld until the toxicity has resolved 
to ≤ Grade 1. If the Grade 3 toxicity does not resolve to ≤ Grade 1 within 21 days, 
all study therapy will be permanently discontinued. 
7.1.3 
Grade 4 Toxicities 
If the patient experiences Grade 4 treatment related hematologic toxicity in either 
study cohort, all study therapy must be permanently discontinued regardless of 
the time to resolution ≤ Grade 1. 
7.2 
Dose Delays for Treatment Related Non-Hematological Toxicity 
See Appendix III for Management Algorithms for Endocrinopathy, Gastrointestinal, 
Hepatic, Neurological, Pulmonary, Renal, and Skin Adverse Events. 
7.2.1 
Grade 1 and Grade 2 Toxicities 
No dose interruptions will be performed for Grade 1 or 2 non-hematologic toxicities, 
except for: 
• 
Any grade hypophysitis, meningitis, immune-related neurological AEs 
• 
Any Grade 2 drug-related uveitis, eye pain, or blurred vision that does not 
respond to topical therapy and does not improve to Grade 1 severity within the 
retreatment period OR requires systemic treatment will require permanent 
discontinuation. 
• 
Colitis (Grade 2) 
• 
AST, ALT, bilirubin (Grade 2) 
• 
Pneumonitis (Grade 2) 
• 
Nephritis (Grade 2)

• 
Infusion reaction that does not resolve within an hour of stopping infusion 
(Section 7.3 for Infusion Reaction Guidelines), or 
• 
Other intolerable or persistent Grade 2 drug-related AE, as per physician 
discretion. 
Discontinue treatment for persistent Grade 2 immunologic AEs (such as colitis, 
pneumonitis, and nephritis) that do not recover to Grade 1 or resolve within 6 weeks 
after the last dose of study drug (Exceptions: rash, fatigue, amylase/lipase 
elevations, other electrolyte abnormalities). 
In addition, discontinue treatment for persistent Grade 2 ALT, AST, or bilirubin that 
do not recover to Grade 1 or resolve within 6 weeks after the last dose of study 
drug. A thorough investigation of the cause of the ALT, AST, or total bilirubin 
elevation is recommended including the exclusion of other causes – e.g. concurrent 
medications, infection, injury, hypo-perfusion, and alcohol consumption. Close 
monitoring of hepatic labs at least weekly and consideration of imaging such as 
ultrasound of the liver is suggested. 
7.2.2 
Grade 3 Toxicities 
Subjects will be required to permanently discontinue all study drugs for the following 
AEs: 
• 
Any Grade 3 non-skin, drug-related AE lasting >7 days or recurs, with the 
following clarifications: 
o 
Grade 3 drug-related uveitis, pneumonitis, myocarditis, bronchospasm, 
hypersensitivity reaction, or infusion reaction of any duration requires 
discontinuation. 
o 
Grade 3 drug-related endocrinopathies, adequately controlled with only 
physiologic hormone replacement, do not require discontinuation. Adrenal 
insufficiency requires discontinuation regardless of control with hormone 
replacement. 
o 
Grade 3 drug-related laboratory abnormalities do not require treatment 
discontinuation except: 
 
Grade ≥ 3 drug-related AST, ALT, or total bilirubin 
 
Concurrent AST or ALT >3x ULN and total bilirubin >2x ULN 
For any other Grade 3 treatment related non-hematologic toxicities, if the Grade 3 
toxicity does not resolve to ≤ Grade 1 within 21 days, all study therapy will be 
permanently discontinued. 
7.2.3 
Grade 4 Toxicities 
If the patient experiences Grade 4 treatment related non-hematologic toxicity in 
either study cohort, all study therapy must be permanently discontinued 
regardless of the time to resolution ≤ Grade 1 with the exception of the following 
instances: 
• 
Grade 4 nausea or emesis which resolves to ≤ Grade 1 within 7 days of optimal 
anti-emetic therapy. 
• 
Grade 4 endocrinopathies that can be mitigated with endocrine replacement 
with resolution to ≤ Grade 1 within 7 days of initiating endocrine replacement 
therapy (i.e. hypothyroid, etc.).

7.3 
Infusion Reaction Guidelines 
Since nivolumab and lirilumab contain only human immunoglobulin protein sequences, each 
is unlikely to be immunogenic and induce an infusion or hypersensitivity reaction. However, 
if such a reaction were to occur, it might manifest with fever, chills, rigors, headache, rash, 
pruritus, arthralgias, hypo- or hypertension, bronchospasm, or other symptoms. All Grade 3 
or 4 infusion reactions should be reported within 24 hours to PrECOG and reported as a 
serious adverse event (SAE) if criteria are met. Infusion reactions should be graded 
according to NCI CTCAE (Version 5.0) guidelines. Treatment recommendations are 
provided below and may be modified based on local treatment standards and guidelines as 
appropriate: 
• 
For Grade 1 symptoms (Mild reaction; infusion interruption not indicated; intervention 
not indicated): 
Remain at bedside and monitor subject until recovery from symptoms. The following 
prophylactic pre-medications are recommended for future infusions: diphenhydramine 
50 mg (or equivalent) and/or paracetamol 325 to 1000 mg (acetaminophen) at least 30 
minutes before additional nivolumab or lirilumab administrations. 
• 
For Grade 2 symptoms (Moderate reaction requires therapy or infusion interruption but 
responds promptly to symptomatic treatment [e.g., antihistamines, non-steroidal anti-
inflammatory drugs, narcotics, corticosteroids, bronchodilators, IV fluids]; prophylactic 
medications indicated for ≤ 24 hours): 
Stop the nivolumab or lirilumab infusion, begin an IV infusion of normal saline (NS), and 
treat the subject with diphenhydramine 50 mg IV (or equivalent) and/or paracetamol 325 
to 1000 mg (acetaminophen); remain at bedside and monitor subject until resolution of 
symptoms. Corticosteroid or bronchodilator therapy may also be administered as 
appropriate. If the infusion is interrupted, restart the infusion at 50% of the original 
infusion rate when symptoms resolve; if no further complications ensue after 30 
minutes, the rate may be increased to 100% of the original infusion rate. Monitor subject 
closely. If symptoms recur then no further nivolumab or lirilumab will be administered at 
that visit. Administer diphenhydramine 50 mg IV, and remain at bedside and monitor 
the subject until resolution of symptoms. The amount of study drug infused must be 
recorded on the electronic case report form (eCRF). The following prophylactic pre-
medications are recommended for future infusions: diphenhydramine 50 mg (or 
equivalent) and/or paracetamol 325 to 1000 mg (acetaminophen) should be 
administered at least 30 minutes before additional nivolumab or lirilumab 
administrations. If necessary, corticosteroids (recommended dose: up to 25 mg of IV 
hydrocortisone or equivalent) may be used. 
• 
For Grade 3 or Grade 4 symptoms (Severe reaction, Grade 3: prolonged [i.e., not rapidly 
responsive to symptomatic medication and/or brief interruption of infusion]; recurrence 
of symptoms following initial improvement; hospitalization indicated for other clinical 
sequelae [e.g., renal impairment, pulmonary infiltrates]; Grade 4: (life threatening; 
pressor or ventilator support indicated): 
Immediately discontinue infusion of nivolumab or lirilumab. Begin an IV infusion of NS, 
and treat the subject as follows. Recommend bronchodilators, epinephrine 0.2 to 1 mg 
of a 1:1,000 solution for subcutaneous administration or 0.1 to 0.25 mg of a 1:10,000 
solution injected slowly for IV administration, and/or diphenhydramine 50 mg IV with 
methylprednisolone 100 mg IV (or equivalent), as needed. Subject should be monitored 
until the investigator is comfortable that the symptoms will not recur. Nivolumab or 
lirilumab will be permanently discontinued. Investigators should follow their institutional 
guidelines for the treatment of anaphylaxis. Remain at bedside and monitor subject until 
recovery from symptoms. In the case of late-occurring hypersensitivity symptoms (e.g.,

symptomatic treatment may be given (e.g., oral antihistamine, or corticosteroids). 
7.4 
Concurrent Therapies 
7.4.1 
Required and/or Permitted 
The following medications and procedures are permitted during the study: 
• 
Anti-emetic medications (with the exception of dexamethasone and/or other 
steroids) are permitted at the treating physician’s discretion. 
• 
Subjects are permitted the use of topical, ocular/auricular, intra-articular, 
intranasal, inhalational steroids, also systemic steroid dose of oral prednisone

in the absence of active autoimmune disease. 
• 
Colony 
stimulating 
growth 
factors 
(i.e. 
erythropoietin, 
darbepoetin, 
pegfilgrastim) are permitted at the treating physician’s discretion. Their use 
should follow American Society of Clinical Oncology (ASCO) guidelines and/or 
label indications/institutional practice. 
• 
Patients should be transfused with red cells and platelets as clinically indicated 
and according to institutional guidelines. However, transfusions may not be 
used to satisfy inclusion criteria for study entry. 
• 
Treatment with full-dose anticoagulation therapy (i.e. warfarin, enoxaparin, 
rivaroxaban, etc.) are permitted at the treating physician’s discretion. 
• 
Supportive measures consistent with optimal patient care may be given 
throughout the study. 
7.4.2 
Prohibited and/or Restricted Treatments 
• 
Immunosuppressive agents are prohibited during the study, unless they are 
utilized to treat an adverse event or as outlined in Section 7.4.1. NSAIDs for 
treatment of osteoarthritis and allopurinol to prevent gout flares is allowed. 
• 
Concurrent administration of any anti-cancer therapies (investigational or 
approved) are also prohibited with the exception of subjects in the follow-up 
period of the study. 
• 
Any medicinal herbal preparation unless prescribed by the treating physician. 
All concomitant medications including prescribed medicinal herbal preparations 
must be documented. 
• 
G-CSF (granulocyte-colony stimulating factor) will be permitted. However, the 
use 
of 
these 
agents 
is 
allowed 
as 
per 
their 
respective 
label 
indications/institutional guidelines to treat neutropenia that occurs on study. G-
CSF must not be used for the treatment of cancer or for any primary prophylaxis 
while on study. 
7.4.3 
Other Restrictions and Precautions 
• 
Any non-oncology live viral vaccine therapies used for the prevention of 
infectious diseases within 4 weeks prior to study drug is prohibited. The use of 
the killed/inactivated vaccines, e.g. seasonal influenza vaccine will be permitted 
on study without restriction. 
• 
Alcohol consumption while on study is strongly discouraged due to the potential 
to confound interpretation of hepatotoxic events.

Study Duration and Discontinuation of Therapy 
8.1 
Study Duration 
Patients will receive protocol therapy unless: 
1. Disease progression per RECIST Version 1.1 criteria or clinical progression. 
2. Toxicities considered unacceptable by either the patient or the investigator, despite 
optimal supportive care and dose delays. 
3. Any requirement to discontinue based on dose delay guidelines in Section 7.1, Section 
7.2, infusion reaction guidelines in Section 7.3 and Appendix III. 
4. Development of an inter-current illness that prevents further administration of study 
treatment. 
5. Extraordinary Medical Circumstances: If at any time the constraints of this protocol are 
detrimental to the patient's health, protocol treatment should be discontinued. 
6. Patient withdraws consent or is unable to comply with study procedures. 
8.2 
Duration of Follow-Up 
Patients will be followed for adverse events for 100 days after their last dose of neoadjuvant 
treatment. Adverse events may be reviewed at the next visit ≥ 100 days after last dose of 
neoadjuvant therapy or phone follow-up may be done to review adverse events. However, 
if a patient experiences an adverse event >100 days after their last dose of study medication 
that is felt to be, in the opinion of the investigator, possibly, probably or definitely related to 
study therapy, the adverse event should be reported. 
Patients will be followed clinically and radiographically per standard of care (3 -6 months) at 
the discretion of the treating physician for at least 2 years post-cystectomy or when study-
wide follow-up ends. Date of diagnosis for progression, first subsequent therapy and survival 
shall be reported. Phone follow-up may also be done for patients unable or unwilling to 
return for follow-up evaluations. 
If a patient is removed from treatment for reason(s) other than progression, follow with 
regular tumor assessments per standard of care until progression or start of new treatment. 
For patients who are registered but do not receive any protocol therapy, baseline and follow-
up information per Section 11 will be collected. 
8.3 
Criteria for Removal from Study Treatment 
A genuine effort will be made to determine the reason(s) why a patient fails to return for the 
necessary visits or is discontinued from the trial, should this occur. It will be documented 
whether or not each patient completed the clinical study. If for any patient study treatment 
or observations were discontinued, the reason will be recorded on the appropriate eCRF. 
Reasons that a patient may discontinue treatment in a clinical study are considered to 
constitute one of the following: 
1. Completion of all study therapy and follow-up. 
2. Recurrence of disease or documented progression of disease. 
3. Intercurrent illness that prevents further administration of treatment per investigator 
discretion. 
4. Unacceptable adverse events. 
5. Investigator and/or patient discontinue study therapy. 
6. Pregnancy.

7. Develops a second malignancy (except low risk cervical cancer or cancer in-situ) that 
requires treatment, which would interfere with this study. 
8. The patient may choose to withdraw from the study at any time for any reason. 
9. General or specific changes in the patient's condition that render the patient 
unacceptable for further treatment in the judgment of the investigator. 
10. Severe non-compliance to protocol as judged by the investigator. 
11. Lost to follow-up. 
12. Death. 
13. Closure of study by PrECOG. 
Any patient who receives at least one dose of nivolumab or lirilumab will be included in the 
safety analysis. Patients who discontinue study treatment early should be followed for 
response assessments, if possible. Follow-up will continue per Section 11, as applicable.

Adverse Event Reporting 
9.1 
Collection of Safety Information 
Adverse Event (AE) is defined as any new untoward medical occurrence or worsening of 
a pre-existing medical condition in a patient administered a medicinal product in a clinical 
investigation and which does not necessarily have a causal relationship with this treatment. 
An AE can therefore be any unfavorable and unintended sign (e.g., including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a product 
(investigational or marketed), whether or not considered related to the product 
(investigational or marketed). 
After informed consent, but prior to initiation of study treatment (nivolumab and lirilumab), 
only AEs/SAEs caused by a protocol-mandated intervention will be collected (e.g., SAEs 
related to invasive procedures such as biopsies). After the initiation of study treatment, all 
identified AEs and SAEs must be recorded and described on the appropriate page of the 
electronic Case Report Form (eCRF). If known, the diagnosis of the underlying illness or 
disorder should be recorded, rather than individual symptoms. The following information 
should be documented for all AEs: date of onset and resolution, severity of the event; the 
investigator’s opinion of the relationship to investigational product (see definitions below); 
treatment required for the AE treatment required for the AE; cause of the event (if known); 
and information regarding resolution/outcome. 
Only clinically significant laboratory abnormalities that require active management will be 
recorded as AEs or SAEs on the eCRF (e.g., abnormalities that require study drug dose 
delay, discontinuation of study treatment, more-frequent follow-up assessments, further 
diagnostic investigation, etc.). 
If the clinically significant laboratory abnormality is a sign of a disease or syndrome (e.g., 
alkaline phosphatase and bilirubin 5x the ULN associated with cholecystitis), only the 
diagnosis (e.g., cholecystitis) needs to be recorded on the Adverse Event eCRF. 
If the clinically significant laboratory abnormality is not a sign of a disease or syndrome, the 
abnormality itself should be recorded as an AE or SAE on the eCRF. If the laboratory 
abnormality can be characterized by a precise clinical term, the clinical term should be 
recorded as the AE or SAE. For example, an elevated serum potassium level of 7.0 mEq/L 
should be recorded as “hyperkalemia”. 
Observations of the same clinically significant laboratory abnormality from visit to visit 
should not be repeatedly recorded as AEs or SAEs on the eCRF unless their severity, 
seriousness, or etiology changes. 
Severity 
The categories and definitions of severity used for clinical trials AEs are defined in the NCI’s 
Common Terminology Criteria (CTCAE) V5.0 (http://www.ctep.cancer.gov). 
Attribution 
The following categories and definitions of causal relationship or attribution to study drug 
should be used to assess Adverse Events: 
• Definite: There is a reasonable causal relationship between the study drug and the event. 
The event response to withdrawal of study drug (dechallenge) and recurs with 
rechallenge, if clinically feasible. 
• Probable: There is a reasonable causal relationship between the study drug and the 
event. The event responds to dechallenge. Rechallenge is not required. 
• Possible: There is a reasonable causal relationship between the study drug and the 
event. Dechallenge information is lacking or unclear. 

PrECOG Protocol Number: PrE0807 
IND Number: 139580 
Confidential 
Date: 12/10/2019 
 
36 
• Unlikely: There is doubtful causal relationship between the study drug and the event. 
• Unrelated: There is clearly not a causal relationship between the study drug and the 
event or there is a causal relationship between another drug, concurrent disease, or 
circumstances and the event. 
Categories ‘definite’, ‘probable’ and ‘possible’ are considered study drug related. Categories 
‘unlikely’ and ‘unrelated’ are considered not study drug-related. 
The development of a new cancer should be regarded as an AE. New cancers are those 
that are not the primary reason for administration of study treatment and have been 
identified after inclusion of the patient into the clinical study. 
AEs related to nivolumab and lirilumab should be followed for 100 days after last 
dose of study therapy until ≤ grade 1 or stabilization, and reported as SAEs if they 
become serious. Any AE’s (serious or not) that occur more than 100 days after the 
last dose of study therapy but that are deemed to be at least possibly related to study 
therapy shall be reported. 
9.2 
Handling of Serious Adverse Events (SAEs) 
9.2.1 
SAE Definitions 
A serious AE is any untoward medical occurrence occurring after initiation of study 
treatment or that at any dose: 
• 
results in death 
• 
is life-threatening (defined as an event in which the study patient was at risk of 
death at the time of the event; it does not refer to an event which hypothetically 
might have caused death if it were more severe) 
• 
requires inpatient hospitalization or causes prolongation of existing 
hospitalization 
• 
results in persistent or significant disability/incapacity 
• 
is a congenital anomaly/birth defect 
• 
is suspected transmission of an infectious agent (e.g., pathogenic or 
nonpathogenic) via the study drug 
• 
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 patient 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. 
9.3 
SAE Reporting Requirements 
Serious adverse events (SAE) are defined above. The investigator should inform PrECOG 
of any SAE within 24 hours of being aware of the event. The date of awareness should be 
noted on the report. This must be documented on the PrECOG SAE form. This form must 
be completed and supplied to PrECOG within 24 hours/1 business day at the latest on the 
following working day. The initial report must be as complete as possible, including details 
of the current illness and (serious) adverse event, and an assessment of the causal 
relationship between the event and the investigational product(s). Information not available 
at the time of the initial report (e.g., an end date for the adverse event or laboratory values 
received after the report) must be documented on a follow-up PrECOG SAE report form. A 
final report to document resolution of the SAE is required. The investigator is responsible

for following all SAEs until resolution, until the subject returns to baseline status, or until the 
condition has stabilized with the expectation that it will remain chronic, even if this extends 
beyond study participation. A copy of the transmission confirmation of the SAE report to 
PrECOG should be attached to the SAE and retained with the patient records. 
SAEs should be scanned and emailed to PrE0807SAE@qdservices.com as per the 
instructions found in study materials provided to the investigator site.

PrECOG will notify BMS or designee of all SAE’s within 24 hours of PrECOG’s & 
Investigator’s Awareness Date as discussed above. Relevant follow-up information will be 
provided to BMS as soon as it becomes available. In addition, every 3 months PrECOG will 
send BMS a listing of all non-serious events (only adverse events not previously submitted). 
Investigators should also report event(s) to their IRB as required. 
Collection of complete information concerning SAEs is extremely important. Full 
descriptions of each event will be followed. Thus, follow-up information which becomes 
available as the SAE evolves, as well as supporting documentation (e.g., hospital discharge 
summaries and autopsy reports), should be collected subsequently, if not available at the 
time of the initial report, and immediately sent using the same procedure as the initial SAE 
report. 
All SAEs, regardless of causality, must be collected which occur within 100 days of last dose 
of study treatment. This includes all deaths within 100 days of last dose of nivolumab and/or 
lirilumab regardless of attribution. In addition, the Investigator should notify PrECOG or 
designee of any SAE that may occur after this time period which they believe to be definitely, 
probably or possibly related to investigational product. 
NOTE: After study closure, study-drug related SAEs should be reported voluntarily by the 
treating physician to the manufacturer. 
Serious adverse event reporting to regulatory authorities and all participating investigators 
will be conducted by PrECOG (or designee) in accordance with 21CFR312.32, local 
requirements and international regulations, as appropriate. FDA reporting requirement 
timelines will be followed. PrECOG will also concurrently forward any such reports to BMS.

Potential Drug-Induced Liver Injury 
All occurrences of potential drug-induced liver injury, meeting the defined criteria below, 
must be reported as SAEs. 
• 
ALT or AST elevation >3 times upper limit of normal (ULN) 
AND 
• 
Total bilirubin >2 times ULN, without initial findings of cholestasis (elevated serum 
alkaline phosphatase) 
AND 
• 
No other immediately apparent possible causes of ALT or AST elevation and 
hyperbilirubinemia, including, but not limited to, viral hepatitis, pre-existing chronic or 
acute liver disease, or the administration of other drug(s) known to be hepatotoxic.

Reporting of Other Second Primary Cancers 
New cancers are those that are not the primary reason for administration of study treatment 
and have been identified after inclusion of the patient into the clinical study. 
All cases of new primary cancers that occur during or after protocol treatment must be 
reported to PrECOG on a Second Primary Cancer form within 30 days of diagnosis, 
regardless of relationship to protocol treatment. Secondary primary malignancies should 
also be reported as a SAE. The SAE form is not for use for reporting recurrence or 
development of metastatic disease. A copy of the pathology report, if applicable, should be 
sent, if available. 
NOTE: Once data regarding survival and remission status are no longer required by the 
protocol, no follow-up data should be submitted. 
9.6 
Procedures in Case of Pregnancy 
Prior to study registration, women of childbearing potential (WOCBP) and male patients with 
a female partner of childbearing potential must be advised of the importance of avoiding 
pregnancy during trial participation and the potential risk factors for an unintentional 
pregnancy, documented in the informed consent. In addition, all WOCBP should be 
instructed to contact the Investigator immediately if they suspect they might be pregnant 
(e.g., missed or late menstrual period) at any time during study participation. 
Pregnancy of a female patient or the female partner of a male patient occurring while the 
patient is receiving study drug or within 5 months after a female patient’s last dose of study 
drug or 7 months for the female partner of a male patient’s last dose of study drug will be 
reported to PrECOG on a SAE Form within 24 hours of the investigator’s knowledge of the 
pregnancy. 
All reports of congenital abnormalities/birth defects and spontaneous miscarriages should 
also be reported and handled as SAEs. Elective abortions without complications should not 
be handled as AEs. 
The outcome of all pregnancies (spontaneous miscarriage, elective termination, normal 
birth including health of the newborn or congenital abnormality) must be followed and 
documented on the Pregnancy Form even if the subject was discontinued from the study 
treatment. Should pregnancy occur during a subject’s participation, the subject will 
immediately be discontinued from the treatment and followed per protocol. 
The SAE Form can be found in the Study Reference Manual. A study specific Pregnancy 
Form will also be completed. 
9.7 
Reporting Guidelines in the Case of Overdose 
Any overdose of a study subject with nivolumab and/or lirilumab, with or without associated 
AEs/SAEs, is required to be reported within 24 hours of knowledge of the event to PrECOG. 
If the overdose results in an AE, the AE must also be recorded as an AE. Overdose does 
not automatically make an AE serious, but if the consequences of the overdose are serious, 
for example death or hospitalization, the event is serious and must be recorded and reported 
as an SAE. There is currently no specific treatment in the event of an overdose of nivolumab 
and/or lirilumab.

Measurement of Effect 
Patients should be evaluated for pathologic tumor response at post-treatment radical cystectomy 
time point. Progression will be evaluated in this study using the new international criteria proposed 
by the revised Response Evaluation Criteria in Solid Tumors (RECIST) guideline Version 1.1 
(Appendix IV).46 RECIST response assessments will be performed locally for the trial. 
10.1 
Evaluable Population Definitions 
Evaluable for Toxicity: All patients will be evaluable for toxicity from the time of their first 
treatment with nivolumab and/or lirilumab. 
Evaluable for Tumor Response: Only those patients who have received at least one dose 
of therapy, and undergo radical cystectomy will be considered evaluable for tumor response. 
These patients will have their tumor response classified according to the definitions stated 
below. (NOTE: Patients who exhibit objective disease progression prior to the end of 
treatment will also be considered evaluable.) 
10.2 
CD8+ T-Cell Density 
The CD8+ T-cell density is defined as the number of CD8+ tumor-infiltrating T-cells per 100 
tumor cells within a 400x high power field (HPF). The CD8+ T-cell density will be calculated 
as: 
Tumor Infiltrating CD8+ T-cell density (CD8+ T-cells per 100 tumor cells) = 
(Total # of CD8+ TILS)/ (Total # of tumor cells per HPF) x 100 
Five representative tumor fields with the greatest gross tumor infiltrating lymphocyte fields 
(minimum 100 tumor cells per representative field) will be chosen for measurement by 
microscope analysis by the pathologist with the final CD8+ T-cell density determined as the 
mean of the CD8+ T-cell density across the five fields. 
10.3 
%CD8+ Tumor-Infiltrating T-Cells 
The %CD8+ tumor-infiltrating T-cells will be quantified by immunohistochemistry (IHC) 
analysis of tissue. Using semi-automated image analysis, a staining percentage determined 
by dividing the area of brown 3,3'-Diaminobenzidine (DAB) staining by the area of epithelial 
cells will be obtained. 
Five representative tumor fields with the greatest gross tumor infiltrating lymphocyte fields 
will be chosen for measurement by the pathologist with the final %CD8+ tumor-infiltrating 
T-cells determined as the mean of the %CD8+ tumor-infiltrating T-cells across the five fields. 
10.4 
Methods for Evaluation of Pathological Response 
The post-treatment pathologic tumor stage will be determined from each patient’s 
cystectomy pathology report according to American Joint Commission on Cancer (AJCC) 
Staging system T, N, M categories for bladder cancer (Appendix V). 
10.5 
Pathologic Tumor Response Definitions 
10.5.1 Pathologic Response 
Pathologic response (<ypT2N0M0) is defined by post-treatment radical cystectomy 
tumor stages with N0 and M0 status with the following T-stages: T0, Ta, Tis, T1. 
10.5.2 Pathologic Complete Response 
Pathologic response (ypCR) is defined by post-treatment radical cystectomy tumor 
stages with N0 and M0 status with the following T-stages: T0.

The administration of nivolumab infusion must be completed within 24 hours of 
preparation. If not used immediately, the infusion solution may be stored under 
refrigeration conditions (2°-8°C, 36°-46°F) for up to 24 hours, and a maximum of 8 
hours of the total 24 hours can be at room temperature (20°-25°C, 68°-77°F) and room 
light. The maximum 8-hour period under room temperature and room light conditions 
includes the product administration period. 
12.1.7 Drug Interactions 
No formal pharmacokinetic drug-drug interaction studies have been conducted with 
nivolumab. 
Nivolumab is not expected to have any effect on cytochrome P450 or other drug 
metabolizing enzymes in terms of inhibition or induction, and is, therefore, not 
expected to induce these types of PK-based drug interactions. 
12.1.8 Agent Availability 
Nivolumab will be supplied by BMS. 
The initial supply of nivolumab will be sent directly to the site upon site activation. As 
needed, nivolumab may be requested by the principal investigator (or their authorized 
designees) at each participating institution. The investigator, or a responsible party 
designated by the investigator, must maintain a careful record of the receipt, 
disposition, and return/destruction (site’s drug destruction policy must be reviewed and 
approved by PrECOG before any study drug can be destroyed at a site) of nivolumab. 
12.1.9 Agent Ordering 
PrECOG will be responsible for ordering drug for re-supply to the site. Requests for 
shipments of nivolumab will be coordinated between PrECOG and BMS. 
12.1.10 Agent Accountability 
Nivolumab will be stored in a secure location. Only authorized pharmacy and study 
staff will have access to this agent. Drug accountability will be performed by PrECOG. 
12.1.11 Side Effects 
The overall safety experience with nivolumab is based on approximately 1500 subjects 
as either a monotherapy or in combination with other therapeutics. In general for 
monotherapy, the safety profile is similar across tumor types. The one exception is 
pulmonary inflammation AEs which may be numerically greater in subjects with Non-
Small Cell Lung Cancer possibly because in some cases it can be difficult to 
distinguish between nivolumab-related and unrelated causes of pulmonary symptoms 
and radiographic changes. The most frequently reported treatment related AE is 
fatigue which is almost always low grade. 
Most related AEs are thought to be due to the effects of inflammatory cells on specific 
tissues. The most common treatment-related adverse events seen in clinical trials of 
nivolumab included rash, pruritus, cough, peripheral edema, fatigue, arthralgias, upper 
respiratory tract infections, diarrhea and liver function test abnormalities. Additionally 
a number of patients experienced more severe autoimmune effects including immune-
mediated pneumonitis, immune-mediated colitis, immune-mediated hepatitis, 
immune-mediated nephritis, immune-mediated encephalitis and immune-mediated 
endocrinopathies, such as adrenal insufficiency, hypothyroidism/hyperthyroidism and 
Type I Diabetes Mellitus. Less than 1% of patients in clinical trials experienced severe 
infusion reactions. 
Nivolumab is a Pregnancy Category D drug.

Statistical Considerations 
13.1 
Study Design & Sample Size Considerations 
This is a Phase Ib study evaluating whether the addition of lirilumab to nivolumab is feasible 
and safe in patients that are either cisplatin-ineligible or refuse cisplatin-based chemotherapy 
and have muscle-invasive urothelial carcinoma of the bladder in the neoadjuvant therapy 
setting. Eligible patients will be assigned sequentially to either nivolumab monotherapy in 
Cohort 1, and if there is no negative safety signal (see next paragraph) after the first 12 
patients, subsequent patients will be assigned to Cohort 2 treated with nivolumab/lirilumab. 
13.1.1 Interim Safety Analysis (Primary Endpoint) 
Treatment-related 
toxicities 
as 
noted 
below 
related 
to 
nivolumab 
or 
nivolumab/lirilumab will be monitored in each cohort of the study separately after 6 and 
12 patients in Cohort 1 and 6 patients in Cohort 2 have completed surgery. There will 
be no suspension to accrual. 
• 
Any Grade hypophysitis, meningitis, or immune-related neurologic AEs 
• 
Grade 2 or higher myocarditis 
• 
Persistent Grade 2 immunologic AEs (such as colitis, pneumonitis, and nephritis) 
that do not recover to Grade 1 or resolve within 6 weeks after the last dose of 
study drug (Exceptions: rash, fatigue, amylase/lipase elevations, other electrolyte 
abnormalities). 
• 
Grade 3 or higher immunologic AEs such as uveitis, pericarditis, hepatitis, 
colitis/diarrhea, nephritis, pancreatitis, myositis, endocrine, rash, etc., except for 
Grade 3 hypothyroidism, Grade 3 pruritus or Grade 3 infusion reaction. 
• 
Grade 4 non immunologic AEs, as well as Grade 4 hypothyroidism or Grade 4 
infusion reaction. 
If 3 or more of these 6 patients on a single cohort experience treatment-related 
adverse events as noted above related to nivolumab or nivolumab/lirilumab, the study 
will be suspended for a safety review. The following table gives the probabilities of 
stopping given various probabilities of toxicity.

13.2.2 Key Secondary Objective 
The key secondary endpoint of this study is the change in tumor-infiltrating CD8+ T-
cell density from TURBT to radical cystectomy in each arm. CD8+ TIL density is 
defined as the number of CD8+ tumor infiltrating T-cells per 100 tumor cells within a 
400x HPF. All biopsies will be reviewed centrally by a pathologist. Final CD8+ T-cell 
density for each patient will be the mean of five representative tumor fields in a 
cystectomy sample with the greatest gross percentage of tumor infiltrating 
lymphocytes (minimum 100 tumor cells per representative field), as selected by the 
pathologist. The mean change in CD8+ TIL density of each cohort will be calculated 
by averaging the change in TIL densities of all patients in the cohort. (Additionally, the 
TIL density at radical cystectomy will be compared between the two cohorts as one of 
the exploratory objectives). 
13.2.2.1 
Analytic Plan for Key Secondary Objective 
The estimate of the standard deviation of tumor-infiltrating CD8+ T-cell 
density in urothelial carcinoma (defined as CD8+ TILs/ 100 tumor cells in 
high power field [HPF]) is derived from a prior study published by Sharma 
et al. In that cohort of 69 patients who underwent cystectomy, the standard 
deviation of TIL density was 3.9.12 Our hypothesis is that the change in 
TIL density between TURBT and radical cystectomy will be approximately 
3.0 CD8+ TILs per 100 tumor cells within HPF. Up to 43 patients will be 
enrolled for 36 eligible, treated patients (12 on nivolumab monotherapy 
and 24 patients on the combination). In each cohort a one-sample 
Wilcoxon signed-rank test will be used to test whether the mean change 
in TIL density differs significantly from zero. In the monotherapy cohort 
there will be 81% power to detect the hypothesized difference with a one-
sided type I error rate of 0.05. In the combination cohort there will be 98% 
power to detect the hypothesized difference with a one-sided type I error 
rate of 0.05. Additionally, the TIL density at radical cystectomy will be 
compared between the two cohorts using a Wilcoxon rank sum test. With 
this design there is 82% power to detect a difference of 0.80 standard 
deviations, which translates to a difference of about 3.0 TILs per 100 
tumor cells, between the two cohorts with a one-sided type I error rate of 
0.1. This comparison will be exploratory in nature. 
13.2.3 Additional Secondary Objectives 
1. The average percentage (%) change in the CD8+ TIL density from TURBT to RC 
in each of the two cohorts. Each individual patient’s percent change will be defined 
as [(Cystectomy TIL Density) – (TURBT TIL Density)] / (TURBT TIL Density). 
2. Proportion of patients in each cohort who do not get a radical cystectomy 
specifically and directly related to treatment related AEs within 6 weeks of the last 
dose of neoadjuvant treatment. 
3. Proportion of patients with pathologic complete (pT0N0) and partial (<pT2N0) 
response in the two cohorts. 
4. Proportion of patients who are alive and free of disease in each cohort at 2 years 
from registration. 
13.2.3.1 
Analytic Plan for Additional Secondary Objectives 
1. The mean percent change of CD8+ TIL density from pre-treatment 
(TURBT) to post-treatment (radical cystectomy) samples in all 12 
patients in Cohort 1 and all 24 patients in Cohort 2 will be calculated

test. 
2. The proportion of patients in each treatment cohort who do not get 
radical cystectomy specifically and directly related to treatment 
related AEs within 6 weeks of the completion of neoadjuvant 
treatment, will be reported along with exact binomial 90% confidence 
intervals for each cohort and compared between the two cohorts 
using Fisher’s exact test. 
3. The proportion of patients in each treatment cohort with pathologic 
complete response (CR) and pathologic partial response (PR) will be 
reported along with exact binomial 90% confidence intervals for each 
cohort. 
4. Recurrence-free survival (defined as patients who are alive and 
without evidence of disease recurrence) from the time of registration 
will be estimated using Kaplan-Meier method for each treatment 
cohort and compared between the two cohorts using a log-rank test. 
One-year and two-year disease-free survival estimates and 
confidence intervals will be provided for each cohort. 
13.2.4 Exploratory Objectives 
1. The relationship between the expression of baseline IHC markers of interest (e.g. 
PD-1, PD-L1, PD-L2, NKG2D, KIR2DL1/2/3), and change in expression, for 
pathologic partial and complete tumor response (defined by cystectomy pathologic 
staging <pT2N0 and pT0N0, respectively), in patients treated with nivolumab and 
combination of nivolumab/lirilumab. To also compare the association of study 
cohort and pathologic response stratified by levels of expression of these 
biomarkers of interest. 
2. The relationship between peripheral blood mononuclear cell (PBMC) T-cell subset 
status (%CD4+ T-cells, %CD8+ T-cells, %Treg T-cells, %Myeloid Derived 
Suppressor Cells, %Natural Killer cells, etc.) and change in status, as assessed 
by flow cytometry analysis, for pathologic partial and complete tumor response 
(defined by cystectomy pathologic staging < pT2N0 and pT0N0, respectively), in 
patients treated with nivolumab and combination of nivolumab/lirilumab. 
3. To compare the CD8+ TIL density at radical cystectomy between the patients 
treated with nivolumab and combination of nivolumab/lirilumab.

treated with nivolumab and combination of nivolumab/lirilumab 
11. To assess CD8+ TIL density by central pathology review using image analysis in 
TURBT and radical cystectomy in each arm. 
13.2.4.1 
Analytic Plan for Exploratory Objectives 
As a general strategy, marker levels in responders vs. non-responders will 
be compared by a t-test or Wilcoxon rank sum test as appropriate. In 
addition to evaluating expression on a continuous scale we will explore 
quantile values for each marker as potential thresholds to discretize the 
marker levels. The two-year RFS will then be compared between marker 
groups with a Fisher’s exact test as well as via time-to-even analyses 
using standard methods for survival analysis. Changes in biomarker 
levels will be computed and compared between groups using a Wilcoxon 
rank sum test. Analyses of the predictive ability of markers will be 
accomplished via standard tests of treatment-by-marker interaction using 
the appropriate model for the endpoint of interest (logistic regression or 
proportional hazards regression). Pearson’s correlation and the Wilcoxon 
signed rank test will be used to characterize the relationship between 
CD8+ TIL densities produced by various methods of assessment. The 
study is not powered for these analyses, however, so conclusions 
regarding the predictive ability of any given marker will be limited.

Laboratory and Pathology Correlative Studies 
14.1 
Correlative Studies: Mandatory Tumor Samples and Analysis 
Kits will be supplied for research samples. Instructions and shipping address will be provided. 
14.1.1 Tumoral Assessments 
• 
Pre-treatment TURBT (archived tissue may be used) 
- 
Up to 3 formalin-fixed paraffin-embedded (FFPE) blocks OR a minimum of 20 
(30 preferred) unstained (5 micron thickness) sections on unbaked, charged 
slides plus 1 H&E slide with highest volume of representative tumor histology. 
• 
Radical Cystectomy 
- 
Up to 3 formalin-fixed paraffin-embedded (FFPE) blocks OR a minimum of 20 
(30 preferred) unstained (5 micron thickness) sections on unbaked, charged 
slides plus 1 H&E slide with highest volume of representative tumor histology. 
• 
At the time of recurrence, if feasible 
- 
Up to 3 formalin-fixed paraffin-embedded (FFPE) blocks OR a minimum of 20 
(30 preferred) unstained (5 micron thickness) sections on unbaked, charged 
slides plus 1 H&E slide with highest volume of representative tumor histology. 
14.1.2 Tumor Infiltrating CD8+ T-Cell Density 
Post-treatment tumor infiltrating CD8+ T-cell density is the secondary endpoint of the 
trial. In pre- and post-treatment tumor tissue specimens CD8+ T-cell density will be 
examined by IHC performed on whole tissue histology sections. The CD8+ T-cell 
density is defined as the number of CD8+ tumor-infiltrating T-cells per 100 tumor cells 
within a 400x HPF.12,45 Five representative tumor fields with the greatest gross tumor 
infiltrating lymphocyte fields (minimum 100 tumor cells per representative field) will be 
chosen for measurement by microscope analysis by the pathologist with the final 
CD8+ T-cell density determined as the mean of the CD8+ T-cell density across the 
five fields. CD8 IHC on both the pre- and post-treatment will be performed by a central 
pathology lab. Pre- and post-treatment CD8+ staining cells intermixed within 
surrounding tumor cells will be considered tumor infiltrating CD8+ T-cells. These cells 
will be counted as will the number of tumor cells within the chosen 400x HPF. The 
CD8+ T-cell density will be calculated as: 
Tumor Infiltrating CD8+ T-cell density (CD8+ T-cells per 100 tumor cells) = 
(Total # of CD8+ TILS)/ (Total # of tumor cells per HPF) x 100 
In addition, CD8+ TIL density will be assessed by central pathology review using 
image analysis of five 1-mm-sq areas using image analysis (Aperio, Leica Biosystem). 
Additionally, eight areas of highest inflammatory infiltrate (“hot-spots”) will be reviewed 
by image analysis to document focal or diffuse process of inflammation. This 
methodology will be utilized to determine both the pre- and post-treatment tumor 
infiltrating CD8+ T-cell densities. 
For additional analysis, tissue microarrays (TMAs) of pre- and post-treatment tumor 
tissue biopsies will be constructed using available tumor FFPE blocks. The TMAs will 
be constructed using three 1.0 mm diameter tumor core tissues containing at least 100 
malignant cells. Also, a minimum of 20 (30 preferred) unstained 5 micron thick sections 
from both the pre- and post-treatment tumor samples will be cut into slides for 
additional correlative investigations. In the event that a patient’s post-treatment TMA 
section is not suitable for averaging three representative tumor infiltrating lymphocyte 
regions, the post-treatment slides may be used for the CD8+ T-cell density analyses.

14.1.3 Percentage CD8+ Tumor Infiltrating T-Cell 
Utilizing tissue slides described above in Section 14.1.2, the %CD8+ tumor infiltrating 
cells pre- and post-treatment will be quantified by semi-automated image analysis. 
CD8+ tumor infiltrating IHC percentage will be determined by dividing the area of 
brown 3,3'-Diaminobenzidine (DAB) staining by the area of epithelial cells within HPF. 
The final %CD8+ tumor infiltrating T-cell measurement will be determined by an 
average of five representative tumor fields with the greatest gross tumor infiltrating 
lymphocytes. 
14.1.4 PD-1 and PD-L1 IHC 
PD-1 and PD-L1 IHC staining will be performed on the TMAs constructed from the 
pre- and post-treatment archived tumor specimens. TMA tumor sections will be 
stained for PD-1 and for PD-L1. All IHC staining will be performed per manufacturer’s 
instructions. 
14.1.5 Banking for Future Research: Additional Analysis 
Other analysis that may be performed depending on resources, tissue quality and 
availability may include the following:

pre-treatment archived tumor specimens. TMA tumor sections will be stained for 
KIR2DL1, KIR2DL2, and KIR2DL3. All IHC staining will be performed per 
manufacturer’s instructions. 
Additional IHC Analyses 
As tissue availability permits, additional IHC and immunofluorescence (IF) staining is 
planned to further characterize functional immune phenotypes and targets of interest 
for future drug development. Utilizing the TMAs constructed from the pre- and post-
treatment archived tumor specimens, additional IHC/IF stains planned, but not limited

Appendix IV: RECIST Version 1.1 
Malignant Disease Evaluation 
Response and progression will be evaluated in this study using the international criteria proposed by the 
revised Response Evaluation Criteria in Solid Tumors (RECIST) guideline Version 1.1. Changes in the largest 
diameter (unidimensional measurement) of the tumor lesions and the shortest diameter in the case of 
malignant lymph nodes are used in RECIST. 
To assess objective response, it is necessary to estimate the overall tumor burden at baseline to which 
subsequent measurements will be compared. Measurable disease is defined by the presence of at least one 
measurable lesion. 
All measurements should be recorded in metric notation by use of a ruler or calipers. The same method of 
assessment and the same technique should be used to characterize each identified lesion at baseline and 
during follow-up. All baseline evaluations should be performed as closely as possible to the beginning of 
treatment and never more than four weeks before registration. 
The term evaluable in reference to measurability will not be used because it does not provide additional 
meaning or accuracy. 
At baseline, tumor lesions will be characterized as either measurable or non-measurable. 
o 
Measurable 
Measurable tumor lesions are those that can be accurately measured in at least one dimension (longest 
diameter in the plane of measurement is to be recorded) with a minimum size of: 
• 
≥ 10 mm by CT scan (irrespective of scanner type) and MRI (no less than double the slice thickness 
and a minimum of 10 mm) 
• 
≥ 10 mm caliper measurement by clinical exam (when superficial) 
• 
≥ 20 mm by chest x-ray (if clearly defined and surrounded by aerated lung) 
If the measurable disease is restricted to a solitary lesion, its neoplastic nature should be confirmed by 
cytology/histology. 
o 
Malignant Lymph Nodes 
To be considered pathologically enlarged and measurable, a lymph node must be ≥ 15 mm in short axis 
(perpendicular to longest diameter) when assessed by CT scan. 
o 
Non-Measurable 
All other lesions (or sites of disease), including small lesions not meeting the criteria in “Measurable” and 
“Malignant Lymph Nodes” above, are considered non-measurable lesions. This includes lymph nodes 
measured at ≥ 10 to <15 mm in the short axis. NOTE: Lymph nodes measured at <10 mm in the short axis 
are considered normal. 
Lesions considered to be non-measurable include the following: leptomeningeal disease, ascites, 
pleural/pericardial effusions, inflammatory breast disease, lymphangitic involvement of the skin or lung, 
and abdominal masses/abdominal organomegaly identified by physical exam that is not measurable by 
reproducible imaging techniques. 
NOTE: 
‘Cystic lesions’ that meet the criteria for radiographically defined simple cysts should not be 
considered as malignant lesions (neither measurable nor non-measurable) since they are, by 
definition, simple cysts. 
‘Cystic lesions’ thought to represent cystic metastases can be considered as measurable lesions, if they 
meet the definition of measurability described above. However, if non-cystic lesions are present in the 
same patient, these are preferred for selection as target lesions.

75 
Lytic bone lesions, with an identifiable soft tissue component, evaluated by CT or MRI, can be considered 
as measurable lesions if the soft tissue component otherwise meets the definition of measurability in 
“Measurable” above. Blastic bone lesions are non-measurable. 
Tumor lesions that are situated in a previously irradiated area, or in an area subjected to other loco-regional 
therapy, are usually not considered measurable unless there has been demonstrated progression in the 
lesion. 
Definitions of Response 
o 
Target Lesions 
All measurable lesions up to a maximum of 2 lesions per organ and 5 lesions in 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 (those with the longest diameters), be representative 
of all involved organs, but in addition should be those that lend themselves to reproducible repeated 
measurements. It may be the case that, on occasion, the largest lesion does not lend itself to reproducible 
measurement in which circumstance the next largest lesion which can be measured reproducibly should 
be selected. 
The sum of the target lesions (longest diameter for non-nodal lesions, short axis for nodal lesions) will be 
calculated and reported as the baseline sum. If lymph nodes are to be included in the sum, then only the 
short axis is added into the sum. The baseline sum of the diameters/axes will be used as reference to 
further characterize any objective tumor regression in the measurable dimension of the disease. 
• 
Complete Response (CR) 
The disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) 
must have reduction in short axis to <10 mm (the sum may not be “0” if there are target nodes). To be 
assigned a status of complete response, changes in tumor measurements must be confirmed by 
repeat assessments performed ≥ 4 weeks after the criteria for response are first met. 
• 
Partial Response (PR) 
At least a 30% decrease in the sum of the diameters/axes of target lesions, taking as reference the 
baseline sum diameters/axes. To be assigned a status of partial response, changes in tumor 
measurements must be confirmed by repeat assessments performed ≥ 4 weeks after the criteria for 
response is met. 
• 
Progressive Disease (PD) 
At least a 20% increase in the sum of the diameters/axes of target lesions, taking as reference the 
smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to 
the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm 
over the nadir. (NOTE: the appearance of one or more new lesions is also considered progression). 
• 
Stable Disease (SD) 
Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as 
reference the smallest sum diameters/axes while on study. (NOTE: a change of 20% or more that 
does not increase the sum of the diameters by 5 mm or more is coded as stable disease). 
To be assigned a status of stable disease, measurements must have met the stable disease criteria 
at least once after study entry at a minimum interval of ≥ 4 weeks. 
o 
Non-Target Lesions 
All other lesions or sites of disease including any measurable lesions over and above the 5 target lesions 
and lymph nodes measured at ≥ 10 to <15 mm in the short axis 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 unequivocal progression of each should be noted throughout follow-up.

• 
Complete Response (CR) 
The disappearance of all non-target lesions and normalization of tumor marker levels, if applicable. All 
lymph nodes must be non-pathological in size (<10 mm short axis). To be assigned a status of 
complete response, changes in tumor measurements must be confirmed by repeat assessments 
performed ≥ 4 weeks after the criteria for response are first met. 
NOTE: If tumor markers are initially above the upper normal limit, they must normalize for a patient to 
be considered in complete clinical response. 
• 
Non-CR/Non-PD 
The persistence of one or more non-target lesion(s) and/or the maintenance of tumor marker levels 
above the normal limits. To be assigned a status of Non-CR/Non-PD, measurements must have met 
the Non-CR/Non-PD criteria at least once after study entry at a minimum interval of ≥ 4 weeks. 
• 
Progressive Disease (PD) 
The appearance of one or more new lesion(s) and/or unequivocal progression of existing non-target 
lesions. Unequivocal progression should not normally trump target lesion status. It must be 
representative of overall disease status change, not a single lesion increase. 
When the patient also has measurable disease, there must be an overall level of substantial worsening 
in non-target disease such that, even in the presence of SD or PR in target disease, the overall tumor 
burden has increased sufficiently to merit discontinuation of therapy. A modest “increase” in the size 
of one or more non-target lesions is usually not sufficient to qualify for unequivocal progression status. 
The designation of overall progression solely on the basis of change in non-target disease in the face 
of SD or PR of target disease will therefore be extremely rare. 
When the patient only has non-measurable disease, the increase in overall disease burden should be 
comparable in magnitude to the increase that would be required to declare PD for measurable disease: 
i.e., an increase in tumor burden from “trace” to “large”, an increase in nodal disease from “localized” 
to “widespread”, or an increase sufficient to require a change in therapy. 
Although a clear progression of “non-target” lesions only is exceptional, the opinion of the treating 
physician should prevail in such circumstances. 
o 
Evaluation of New Lesions 
The appearance of new lesions constitutes Progressive Disease (PD). 
o 
Symptomatic Deterioration 
Patients with a global deterioration of health status requiring discontinuation of treatment without objective 
evidence of disease progression at that time should be reported as “symptomatic deterioration”. Every 
effort should be made to document the objective progression even after discontinuation of treatment. 
Evaluation of Patient’s Best Overall Response 
The best overall response is the best response recorded from the start of the treatment until confirmed disease 
progression or non-protocol therapy (taking as reference for progressive disease the smallest measurements 
recorded since the treatment started). The patient's best response assignment will depend on the achievement 
of both measurement and confirmation criteria (Table V-1). 
To be assigned a status of complete or partial response, changes in tumor measurements must be confirmed 
by repeat assessments performed ≥ 4 weeks after the criteria for response are first met. 
To be assigned a status of stable disease, measurements must have met the stable disease criteria at least 
once after study entry at a minimum interval of ≥ 4 weeks.

should be the same as was used at baseline and the lesions should be measured/assessed on the same 
pulse sequence. It is beyond the scope of the RECIST guidelines to prescribe specific MRI pulse sequence 
parameters for all scanners, body parts, and diseases. Ideally, the same type of scanner should be used 
and the image acquisition protocol should be followed as closely as possible to prior scans. Body scans 
should be performed with breath-hold scanning techniques, if possible. 
o 
PET-CT 
At present, the low dose or attenuation correction CT portion of a combined PET-CT is not always of 
optimal diagnostic CT quality for use with RECIST measurements. However, if the site can document that 
the CT performed as part of a PET-CT is of identical diagnostic quality to a diagnostic CT (with IV and oral 
contrast), then the CT portion of the PET-CT can be used for RECIST measurements and can be used 
interchangeably with conventional CT in accurately measuring cancer lesions over time. Note, however, 
that the PET portion of the CT introduces additional data which may bias an investigator if it is not routinely 
or serially performed. 
o 
Ultrasound 
Ultrasound is not useful in assessment of lesion size and should not be used as a method of measurement. 
Ultrasound examinations cannot be reproduced in their entirety for independent review at a later date and, 
because they are operator dependent, it cannot be guaranteed that the same technique and 
measurements will be taken from one assessment to the next. If new lesions are identified by ultrasound 
in the course of the study, confirmation by CT or MRI is advised. If there is concern about radiation 
exposure at CT, MRI may be used instead of CT in selected instances. 
o 
Endoscopy, Laparoscopy 
The utilization of these techniques for objective tumor evaluation is not advised. However, such techniques 
may be useful to confirm complete pathological response when biopsies are obtained or to determine 
relapse in trials where recurrence following CR or surgical resection is an endpoint. 
o 
Tumor Markers 
Tumor markers alone cannot be used to assess response. If markers are initially above the upper normal 
limit, they must normalize for a patient to be considered in complete clinical response. 
o 
Cytology, Histology 
These techniques can be used to differentiate between PR and CR in rare cases (e.g., residual lesions in 
tumor types, such as germ cell tumors, where known residual benign tumors can remain). 
The cytological confirmation of the neoplastic origin of any effusion that appears or worsens during 
treatment when the measurable tumor has met criteria for response or SD is mandatory to differentiate 
between response or SD (an effusion may be a side effect of the treatment) and PD.
