administration prohibited by paclitaxel related toxicity, or investigator discretion with CR after 6 cycles.  In the case of 
pembrolizumab toxicity, paclitaxel should be continued alone until progression, unacceptable toxicity, or investigator 
discretion with CR after 6 cycles.  In the case of paclitaxel discontinuation, pembrolizumab should be continued until 
progression or toxicity.

4.0 BACKGROUND & RATIONALE 
4.1 
Background 
4.1.1 Pharmaceutical and Therapeutic Background 
The importance of intact immune surveillance in controlling outgrowth of neoplastic 
transformation has been known for decades [1].  Accumulating evidence shows a correlation 
between tumor-infiltrating lymphocytes (TILs) in cancer tissue and favorable prognosis in 
various malignancies [2-6].  In particular, the presence of CD8+ T-cells and the ratio of 
CD8+ effector T-cells / FoxP3+ regulatory T-cells seems to correlate with improved 
prognosis and long-term survival in many solid tumors. 
The PD-1 receptor-ligand interaction is a major pathway hijacked by tumors to suppress 
immune control.  The normal function of PD-1, expressed on the cell surface of activated T-

cells under healthy conditions, is to down-modulate unwanted or excessive immune 
responses, including autoimmune reactions.  PD-1 (encoded by the gene Pdcd1) is an Ig 
superfamily member related to CD28 and CTLA-4 which has been shown to negatively 
regulate antigen receptor signaling upon engagement of its ligands (PD-L1 and/or PD-L2) 
[7,8].  The structure of murine PD-1 has been resolved [9].  PD-1 and family members are 
type I transmembrane glycoproteins containing an Ig Variable-type (V-type) domain 
responsible for ligand binding and a cytoplasmic tail which is responsible for the binding of 
signaling molecules. The cytoplasmic tail of PD-1 contains 2 tyrosine-based signaling motifs, 
an immunoreceptor tyrosine-based inhibition motif (ITIM) and an immunoreceptor tyrosine-
based switch motif (ITSM). Following T-cell stimulation, PD-1 recruits the tyrosine 
phosphatases SHP-1 and SHP-2 to the ITSM within its cytoplasmic tail, leading to the 
dephosphorylation of effector molecules such as CD3ζ, PKCθ and ZAP70 which are 
involved in the CD3 T-cell signaling cascade [7,10-12]. The mechanism by which PD-1 
down modulates T-cell responses is similar to, but distinct from that of CTLA-4 as both 
molecules regulate an overlapping set of signaling proteins [13,14].  PD-1 was shown to be 
expressed on activated lymphocytes including peripheral CD4+ and CD8+ T-cells, B-cells, T 
regs and Natural Killer cells [15,16]. Expression has also been shown during thymic 
development on CD4-CD8- (double negative) T-cells as well as subsets of macrophages and 
dendritic cells [17].  The ligands for PD-1 (PD-L1 and PD-L2) are constitutively expressed 
or can be induced in a variety of cell types, including non-hematopoietic tissues as well as in 
various tumors [13,18-20].  Both ligands are type I transmembrane receptors containing both 
IgV- and IgC-like domains in the extracellular region and contain short cytoplasmic regions 
with no known signaling motifs. Binding of either PD-1 ligand to PD-1 inhibits T-cell 
activation triggered through the T-cell receptor. PD-L1 is expressed at low levels on various 
non-hematopoietic tissues, most notably on vascular endothelium, whereas PD-L2 protein is 
only detectably expressed on antigen-presenting cells found in lymphoid tissue or chronic 
inflammatory environments. PD-L2 is thought to control immune T-cell activation in 
lymphoid organs, whereas PD-L1 serves to dampen unwarranted T-cell function in peripheral 
tissues [13].  Although healthy organs express little (if any) PD-L1, a variety of cancers were 
demonstrated to express abundant levels of this T-cell inhibitor.  PD-1 has been suggested to 
regulate tumor-specific T-cell expansion in subjects with melanoma (MEL) [21]. This 
suggests that the PD-1/PD-L1 pathway plays a critical role in tumor immune evasion and 
should be considered as an attractive target for therapeutic intervention. 
Pembrolizumab (previously known as SCH 900475 and MK-3475) is a potent and highly 
selective humanized monoclonal antibody (mAb) of the IgG4/kappa isotype designed to 
directly block the interaction between PD-1 and its ligands, PD-L1 and PD-L2.

4.2 
Rationale 
4.2.1 Rationale for the Trial and Selected Subject Population 
In the United States, epithelial ovarian cancer is the second most frequent gynecologic 
malignancy; however, due to diagnosis at advanced stage and resistance to therapy it is the 
leading cause of death from gynecologic malignancy. Each year approximately 26,000 
women will be diagnosed with ovarian cancer and 15,000 will die from the disease.  Most 
patients will have recurrent disease and receive several lines of chemotherapy.  The treatment 
of recurrent ovarian cancer is difficult due to drug resistance even after initial response. 
Many compounds and combinations have been evaluated such as liposomal doxorubicin, 
topotecan, docetaxel, and paclitaxel. It has also been demonstrated that the weekly 
administration of paclitaxel leads to responses in platinum- and taxane-resistant cancers 
[22,23]. 
There is evidence in platinum-resistant ovarian cancer that the weekly administration of 
paclitaxel leads to better tolerance with decreased myelosuppression (i.e. GOG protocol 
126N). Weekly paclitaxel (80 mg/m2/week) in this setting showed an objective response rate 
of 20.9% (two CRs, eight PRs) among 48 evaluable patients.  Serious adverse events were 
relatively uncommon with 21% of patients experiencing grade 2 neuropathy and only 4% 
developing grade 3 neuropathy. In the randomized comparison of weekly paclitaxel to every 
3-week paclitaxel, Rosenberg and colleagues showed that (at equivalent dose intensity) the 
weekly regimen (RR = 19%) was better tolerated without compromising efficacy [24]. 
Weekly paclitaxel has gained widespread use as a standard treatment of recurrent, platinum 
resistant ovarian cancer.  Many recent and ongoing randomized trials in recurrent ovarian 
cancer are using weekly paclitaxel in the control arm (i.e. TRINOVA-1, MITO-11, 
AURELIA, ESP2011-002). There is additional evidence suggesting that dose-dense 
chemotherapy improves mechanisms of antitumor immune response [25] as well as adding 
anti-angiogenic properties [26]. Furthermore, there may be synergistic activity between anti-
angiogenic therapy and immunotherapy [27].   
For platinum resistant disease, the recent AURELIA trial compared three different 
chemotherapies with or without bevacizumab [28]. This trial allowed patients whose disease 
had recurred within 6 months of prior platinum therapy, and up to 2 prior therapies, to get 
one of 3 investigator-preselected chemotherapies (weekly paclitaxel, liposomal doxorubicin, 
or topotecan) and then randomized the bevacizumab.  There was an approximate doubling of 
the median PFS 3.4 (2.2-3.7) to 6.7 (5.7-7.9).  The 6-month PFS, although not reported, can 
be closely estimated from the PFS graph in the reported manuscript and is approximately 
0.25 on the high end of the control confidence interval (CI), and 0.5 on the low end of the 
experimental arm CI.  The statistically significant improvement has led to a pending FDA 
approval application.  Although the chemotherapy was not randomized, the weekly paclitaxel 
arm had a non-statistically significant trend toward better PFS.   
Additionally, some have suggested that this may represent the bar for a new platinum 
resistant single agent or combination therapy to achieve.  However, there may be different

7 
Protocol/Amendment No.:  Version 4, November 21, 2017 
 
 
 
 
populations that ultimately benefit from bevacizumab versus immunotherapy (e.g. PD1 
directed therapy). Weekly paclitaxel may impart new attributes to angiogenic or 
immunotherapy strategies.  It is reasonable to first see if the combination of paclitaxel and 
Pembrolizumab appears superior to the current standard of paclitaxel alone.  If so, and if this 
doublet is tolerable (and bevacizumab gets approval for this setting), a next consideration 
may be to look at triplet combination therapy (Bev+Pacl vs Bev+Pembro+Pacl), or even 
compare doublets (Bev+Pacl vs Pembro+Pacl).   
In the platinum resistant ovarian cancer setting, the number of previous therapies does not 
seem to greatly change the overall response rate or PFS of tumors to therapy.  This likely 
stems from the overall poor response rate in general (approximately 11-21%) (GOG 126 
series) and poor PFS. Recognizing this, recent industry randomized phase 2 and phase 3 trials 
using weekly paclitaxel in this setting have allowed up to 3 prior treatments [29,30]).   The 
authors noted that comparison of activity (PFS) to lines of therapies revealed no differences.  
Randomized studies with weekly paclitaxel, such as TRINOVA-1, appear to have better PFS 
compared to others such as AURELIA and MITO-11, despite the fact that TRINOVA-1 
allowed up to 25% with 3-prior therapies and the latter trials only allowed up to 2.  This is 
because PFS is primarily a function of recurrence interval from prior platinum, i.e. 
TRINOVA-1, but not the others, allowed semi-resistant 6-12 month platinum free patients to 
be included.  (Table 11).[28,30,31]  
Furthermore, the number of lines of therapy may have even less meaning for an agent that 
works via activating an immune mechanism, rather than reliance on tumor 
sensivity/resistance. Therefore, the number of lines of therapy, referring to chemotherapy, 
may make sense primarily in the context of chemotherapy.  It may lose meaning even in 
platinum sensitive disease, where the number of lines of therapy has more meaning.  
4.2.2 Rationale for Dose Selection/Regimen/Modification  
Pembrolizumab (MK-3475):  200 mg Q3W 
 
In an open-label, solid-tumor, Phase I trial (Protocol 001) to evaluate the safety and clinical 
activity of single agent pembrolizumab (MK-3475), three dose levels (1 mg/kg, 3 mg/kg, and 
10 mg/kg) were administered every 2 weeks (Q2W) in subjects with advanced solid tumors.  
All three dose levels were well tolerated and no dose-limiting toxicities were observed. This 
first-in-human study of pembrolizumab (MK-3475) showed evidence of target engagement 
and objective evidence of tumor size reduction at all dose levels (1 mg/kg, 3 mg/kg and 10 
mg/kg Q2W). No MTD has been identified to date. 10.0 mg/kg Q2W, the highest dose tested 
in PN001, became the dose and schedule utilized in further cohorts. However, some data 
from other clinical studies within the pembrolizumab (MK-3475) program have shown that a 
lower dose of pembrolizumab (MK-3475) and a less frequent schedule may be sufficient for 
target engagement and clinical activity. 
 
PK data analysis of pembrolizumab (MK-3475) administered Q2W and Q3W show slow 
systemic clearance, limited volume of distribution, and a long half-life (refer to IB).  
Pharmacodynamic data (IL-2 release assay) suggest that peripheral target engagement is 

Product:  Pembrolizumab (MK-3475)  
8 
Protocol/Amendment No.:  Version 4, November 21, 2017 
 
 
 
 
durable (>21 days).  The early PK and pharmacodynamic data provided scientific rationale 
for testing both Q2W and Q3W dosing schedule.   
 
A population pharmacokinetic analysis has been performed using serum concentration time 
data from 476 patients. Within the resulting population PK model, clearance and volume 
parameters of pembrolizumab (MK-3475) were found to be dependent on body weight. The 
relationship between clearance and body weight, with an allometric exponent of 0.59, is 
within the range observed for other antibodies and would support both body weight 
normalized dosing or a fixed dose across all body weights. Pembrolizumab (MK-3475) has 
been found to have a wide therapeutic range based on the melanoma indication. The 
differences in exposure for a 200 mg fixed dose regimen relative to a 2 mg/kg Q3W body 
weight-based regimen are anticipated to remain well within the established exposure margins 
of 0.5 – 5.0 for pembrolizumab (MK-3475) in the melanoma indication. The exposure 
margins are based on the notion of similar efficacy and safety in melanoma at 10 mg/kg 
Q3W vs. the proposed dose regimen of 2 mg/kg Q3W (i.e. 5-fold higher dose and exposure). 
The population PK evaluation revealed that there was no significant impact of tumor burden 
on exposure. In addition, exposure was similar between the NSCLC and melanoma 
indications. Therefore, there are no anticipated changes in exposure between different 
indication settings.  
 
Further studies have looked at the safety and PK parameters using 200 mg as a single adult 
dose without adjustment for weight given on an every 3 week schedule. This dose is 
currently being used in several new and ongoing studies (i.e. MK-3475-012/KEYNOTE-
012/NCT01848834, 
MK-3475-031/NCT02212730, 
MK-3475-021/KEYNOTE-021/ 
NCT02039674, 
(MK-3475-023/KEYNOTE-023/NCT02036502, 
and 
(MK-3475-
042/KEYNOTE-042/ NCT02220894) and has been the dose recommended for use in future 
trials of pembrolizumab by Merck.   
 
Paclitaxel: 80 mg/m² days 1, 8, 15 q 21d 
Weekly Paclitaxel as a Single Agent:  
In patients with platinum-taxane refractory ovarian cancer, retreatment with paclitaxel using 
a weekly schedule has demonstrated activity, possibly through anti-angiogenic as well as 
direct cytotoxic mechanisms. GOG-0126N demonstrated a 21% objective response rate (and 
a 46% rate of stable disease) in this population [32]. 
Recent and current randomized phase 3 trials [29,31] in recurrent ovarian cancer that have 
utilized a designated backbone of weekly paclitaxel have used 80 mg/m2 on days 1, 8, and 15 
of a 28-day cycle.  The AURELIA study used continuous weekly dosing at 80 mg/m2 on a 
28-day cycle.  This trial will use the same continuous weekly dosing, however, on a 3-week 
cycle to mirror the Pembrolizumab schedule. Assessments will be at 9-week (3 cycle) 
intervals, rather than 8-week (2 cycle) intervals in the AURELIA trial.  The effect of this 
should be quite minimal. [28]. 
*Cycle 1 has no Pembrolizumab given during a lead-in week in first cycle.  Only this cycle 
consists of 4 weeks, with week 2 (cycle 1, day 8) marking the first dose of Pembrolizumab.

Steroids are eliminated starting cycle 1, day 8 if no hypersensitivity reaction (HSR) occurred 
during Cycle 1, day 1 administration of Paclitaxel.  The addition of steroids, if needed for 
subsequent weekly paclitaxel, may diminish the effect of Pembrolizumab. [33] 
4.2.3 Rationale for Primary Endpoints 
Primary: Progression Free Survival at 6-months (6-month PFS) 
PFS is the appropriate endpoint for this study both in terms of the disease and the agents 
being studied.  Recurrent ovarian cancer is not considered curable.  Drugs that provide longer 
durations of disease and symptom control are generally preferred over drugs that do not, even 
if the latter drugs might provide temporary reductions in tumor measurements (response).  A 
patient who lacks progression on an agent in this setting is generally better off remaining on 
treatment despite a lack of response, as subsequent regimens are unlikely to be beneficial. 
Most recent and current randomized studies in recurrent ovarian cancer use PFS as the 
primary endpoint. The FDA has provided approval of new regimens based upon this endpoint 
(i.e. gemcitabine + carboplatin) [34]. In terms of pembrolizumab (MK-3475), the mechanism 
of this drug may be associated with tumor suppression without measurable disease reduction 
in some patients, despite a possible long-term disease control rate. Additionally, the 
relatively small 6-month PFS in this population (GOG 126 series, communication) proposed 
makes it a feasible endpoint to study. 
Safety: Given the relatively well-documented toxicities associated with dose-dense 
paclitaxel and the lack of anticipated overlapping toxicities with pembrolizumab (MK-3475), 
it is deemed reasonable to conduct a phase II trial with the combination.  It is not anticipated 
that the safety profile of pembrolizumab will change with the addition of paclitaxel.  
However, the accurate prospective measurement of toxicities and a descriptive comparison to 
treatment with dose-dense paclitaxel only is important, particularly if there appears to be an 
improvement in the PFS hazard ratio. 
Immunotherapy has been combined with paclitaxel in cancer patients.  In a phase II study in 
NSCLC, grade 3/4 events were not different between 204 patients receiving ipilimumab or 
placebo with carboplatin and paclitaxel.  A multi-arm phase II study that combines 
Pembrolizumab with paclitaxel 200mg/m2 (and carboplatin AUC 6) is currently underway 
(KEYNOTE-021).   
4.2.3.1 Efficacy Endpoints 
Primary Objectives: 
• Efficacy:  To estimate the 6-month progression-free survival of the combination of 
weekly paclitaxel with pembrolizumab (MK-3475) and to compare to historical weekly 
paclitaxel alone in patients with persistent or recurrent ovarian, fallopian tube, or primary 
peritoneal cancer.

Protocol/Amendment No.:  Version 4, November 21, 2017 
 
 
 
 
• Safety:  To determine the frequency and severity of adverse events associated with 
treatment with weekly paclitaxel with pembrolizumab (MK-3475) in this population of 
patients as assessed by CTCAE. 
 
Secondary Objectives: 
• To estimate the proportion of patients who respond to the regimen by RECIST v1.1, 
RECIST based immune-related response criteria (irRC), and exploration of CA125 
Rustin Criteria.   
• To assess the Disease Control Rate (DCR), and Duration of Response (DOR) in the study 
population. 
• To assess median Overall Survival (OS) in the study population. 
 
4.2.3.2 Biomarker Research 
There is the potential that certain immune markers may predict response to immunotherapy 
agents.  PD-L1 overexpression correlates with malignancy and immune regulation in ovarian 
cancer [35]. PD-L1 has been suggested to predict anti-PD-1 responses [35]-[36].  In a phase 
1 trial of pembrolizumab (MK-3475), pretreatment tumor PD-L1 expression by 
immunohistochemistry (IHC) was a statistically significant predictor of response [37]. 
Therefore, tumor samples must be available from diagnosis to be examined by IHC in all 
patients (to be analyzed if a significant level of activity is ultimately seen).  Also, as 
mentioned above, a study in patients with ovarian cancer demonstrated the ability to examine 
peripheral blood mononuclear cells (PBMC) for PD-L1 expression and that it correlates with 
PD-1 expression in TILs in malignant tumors [35]. Other reports have also noted panels of 
markers that may be predictive and the data continue to evolve.  Therefore, PBMCs will be 
collected pre and post treatment in participating patients and analyzed if study reaches an 
endpoint that demonstrates significant clinical activity. Pending additional funding and an 
amendment to the protocol, pretreatment and post-treatment biopsies may be obtained in a 
portion of study slots reserved for patients who are willing to participate in these biopsies. 
These tumors can be examined for TILs and PD-1 expression, and tumor tissue expression of 
PD-L1 (+/- other markers, i.e., IDO, LAG-3, TIM-3, ICOS, etc.).  Separate reporting will be 
made looking for an association between PFS and RR with PD-L1 positive tumors.  Other 
associations with markers will be explored.

7. Prior Therapy 
a. Patients must have had one prior platinum-based chemotherapeutic regimen 
for management of primary disease containing carboplatin, cisplatin, or 
another organoplatinum compound. This initial treatment may have included 
intraperitoneal therapy, consolidation, non-cytotoxic agents (biologic/ 
targeted) or extended therapy administered after surgical or non-surgical 
assessment. If patients were treated initially with paclitaxel for their primary 
disease, this can have been given weekly or every 3 weeks.  The most recent 
therapy and any therapies subsequent to initial therapy, however, cannot have 
contained weekly paclitaxel.  If the immediate prior (most recent therapy) is 
the initial therapy, it may not have been with weekly paclitaxel. 
b. Patients are allowed to receive, but are not required to receive, two additional 
cytotoxic regimens for management of recurrent or persistent disease, with no 
more than 1 non-platinum regimen. Treatment with weekly paclitaxel for 
recurrent or persistent disease is NOT allowed. 
c. Patients are allowed to receive, but are not required to receive, non-cytotoxic 
(biologic/targeted) therapy as part of their primary treatment regimen. Patients 
are allowed to receive, but are not required to receive, non-cytotoxic 
(biologic/targeted) therapy as part of their treatment for recurrent or persistent 
disease and/or as treatment for recurrent or persistent disease. If non-cytotoxic 
(biologic/targeted) therapy is given alone (i.e., not in combination with 
cytotoxic chemotherapy) it will NOT count as a prior regimen. 
8. Have tissue from an archival tissue sample that has been identified and confirmed as 
available for study, or newly obtained core or excisional biopsy of a tumor lesion. 
9. Patients who have received one prior regimen must have an ECOG Performance 
Status of 0, 1, or 2.  
Patients who have received two or three prior regimens must have an ECOG 
Performance Status of 0 or 1. 
10. Patients must demonstrate adequate organ function as defined in Table 1, all 
screening labs should be performed within 10 days of treatment initiation.

5.2.1 Dose Selection/Modification 
5.2.1.1 Dose Selection 
The rationale for selection of doses to be used in this trial is provided in Section 4.0 – 
Background and Rationale.   
The dose amount required to prepare the pembrolizumab (MK-3475) infusion solution will 
not be based on the subject’s weight.  The dose amount required to prepare Paclitaxel will be 
based on a calculation of the patient’s body surface area (BSA) in mg/m2.  There is no 
maximum BSA.

Dosing interruptions are permitted in the case of medical / surgical events or logistical 
reasons not related to study therapy (e.g., elective surgery, unrelated medical events, patient 
vacation, and/or holidays). Subjects should be placed back on study therapy within 3 weeks 
of the scheduled interruption, unless otherwise discussed with the Sponsor. The reason for 
interruption should be documented in the patient's study record. 
In case toxicity does not resolve to Grade 0-1 within 12 weeks after last infusion, trial 
treatment should be discontinued after consultation with the Sponsor.  With investigator and 
Sponsor agreement, subjects with a laboratory adverse event still at Grade 2 after 12 weeks 
may continue treatment in the trial only if asymptomatic and controlled.  For information on 
the management of adverse events, see Section 5.6.1.   
Subjects who experience a recurrence of the same severe or life-threatening event (grade 3 or 
4) at the same grade or greater with re-challenge of pembrolizumab (MK-3475) should be 
discontinued from trial treatment. 
Subjects who must discontinue pembrolizumab, but are without progression and tolerating 
paclitaxel, should continue to receive paclitaxel.  Subjects who must discontinue paclitaxel, 
but are without progression and tolerating pembrolizumab, should continue to receive 
pembrolizumab.  Treatment continues until progression or subsequent limiting toxicity.  In 
the case of paclitaxel only therapy because of pembrolizumab toxicity, paclitaxel can be 
discontinued if a CR is achieved and at least 6 cycles have been administered.   
PACLITAXEL 
• Formulation: Paclitaxel is supplied as a 6mg/mL non-aqueous solution in multi-dose 
vials containing 30mg/5mL, 100mg/16.7mL, or 300mg/50mL of paclitaxel. In 
addition to 6mg of paclitaxel, each mL of sterile non-pyrogenic solution contains 
527mg of purified Cremophor® EL (polyoxyethylated castor oil) and 49.7% (v/v) 
dehydrated alcohol, USP.  
• Storage: Unopened vials of paclitaxel are stable to the date indicated on the package 
when stored between 20 to 25°C (68 to 77°F). Protect from light.  

Product:  Pembrolizumab (MK-3475)  
19 
Protocol/Amendment No.:  Version 4, November 21, 2017 
 
 
 
 
• Stability: Commercially available paclitaxel will be labeled with an expiration date. 
All solutions of paclitaxel exhibit a slight haziness directly proportional to the 
concentration of drug and the time elapsed after preparation, although when prepared 
as described below, solutions of paclitaxel (0.3-1.2 mg/ml) are physically and 
chemically stable for 27 hours. 
 
• Preparation: Paclitaxel must be diluted prior to infusion. Paclitaxel should be diluted 
in 0.9% Sodium Chloride for Injection, USP; 5% Dextrose Injection, USP; 5% 
Dextrose and 0.9% Sodium Chloride Injection, USP; or 5% Dextrose in Ringer’s 
Injection to a final concentration of 0.3 to 1.2mg/mL. The solutions are physically 
and chemically stable for up to 27 hours at ambient temperature (approximately 25°C 
/ 77°F) and room lighting conditions.  
 
• NOTE: In order to minimize patient exposure to the plasticizer DEHP, which may be 
leached from PVC infusion bags or sets, diluted paclitaxel solutions should be stored 
in bottles (glass, polypropylene) or plastic (polypropylene, polyolefin) bags and 
administered through polyethylene-lined administration sets. Paclitaxel should be 
administered through an inline filter with a microporous membrane not greater than 
0.22 microns. Use of filter devices such as IVEX-2® or IVEX-HP®, which 
incorporate short inlet and outlet PVC-coated tubing has not resulted in significant 
leaching of DEHP.  
 
• All patients should be premedicated with diphenhydramine, and H2 antagonists prior 
to paclitaxel administration in order to prevent severe hypersensitivity reactions. 
Please see the specific premedication instructions in section 5.2.2.  Patients who 
experience severe hypersensitivity reactions to paclitaxel should not be re-challenged 
with the drug. 
 
• Adverse Effects: Consult the package insert for the most current and complete 
information. 
 
• Supplier/ How Supplied: Commercially available both from Bristol-Myers Squibb 
Oncology as well as generic manufacturers. Consult the American Hospital 
Formulary Service Drug Information guide, Facts and Comparisons, or the package

Please note all CTCAE grading below refers to the CTCAE version 4.0.  
Hematologic toxicity  
• Initial treatment modifications will consist of cycle delay and/or dose reduction as 
indicated below. The use of hematopoietic cytokines and protective reagents are 
restricted as noted:  
o Patients will NOT receive prophylactic growth factors [filgrastim (G-CSF), 
sargramostim (GM-CSF), pegfilgrastim (Neulasta)] unless they experience 
recurrent neutropenic complications after treatment modifications specified 
below.  
o Patients will NOT receive prophylactic thrombopoietic agents. Patients may 
not receive a platelet transfusion in the 21 days prior to cycle 1.  It is not 
acceptable to transfuse patients who do not have an adequate level of platelets 
so that they qualify for study.  However, patients who are on study and 
develop thrombocytopenia, may be transfused for any reason felt clinically 
indicated, including sustained tolerability of therapy, by their treating 
physicians.  
o Patients may receive erythropoietin (EPO), iron supplements, and/or 
transfusions as clinically indicated for management of anemia. Treating 
physicians should be aware of the recent changes in prescribing information 
for the erythropoiesis stimulating agents (including Aranesp, Epogen and 
Procrit) which note that there is a potential risk of shortening the time to 
tumor progression or disease-free survival, and that these agents are 
administered only to avoid red blood cell transfusions. They do not alleviate 
fatigue or increase energy. They should not be used in patients with 
uncontrolled hypertension. They can cause an increased incidence of 
thrombotic events in cancer patients on chemotherapy.  Updated package 
inserts should be consulted. 
  http://www.fda.gov/Medwatch/safety/2007/safety07.htm  
o Patients may NOT receive amifostine or other protective reagents.  
• Treatment decisions will be based on the absolute neutrophil count (ANC) rather than 
the total white cell count (WBC). 
• Subsequent cycles of therapy will not begin until the ANC is at least 1500 cells/mcl 
and the platelet count is at least 100,000/mcl. Therapy will be delayed for a maximum 
of two weeks until these values are achieved. Patients who fail to recover adequate 
counts within a two-week delay will have paclitaxel discontinued, but should 
continue pembrolizumab alone. . 
• Uncomplicated granulocyte nadirs (<1500 cells/mcl) that delay the next cycle by 7 or 
more days may, at the discretion of the treating investigator, receive growth factors 
(filgrastim) according to institutional standards. Ideally, filgrastim should be 
discontinued before or when the ANC is approximately 10,000 cells/mcl.  Patients 
must be 24 hours or more from the last dose of filgrastim before receiving treatment. 
• The day 8 and 15 paclitaxel dose will not be given unless the ANC is at least 500 
cells/mcl and the platelet count is as least 50,000/mcl. If not given, these doses are 
omitted and not made up.  For ANC values between 500 to 999 where paclitaxel is 
administered, the use of filgrastim is permissible following administration if deemed 

Product:  Pembrolizumab (MK-3475)  
21 
Protocol/Amendment No.:  Version 4, November 21, 2017 
 
 
 
 
clinically appropriate.   
• For first occurrence of febrile neutropenia, and/or documented grade 4 neutropenia 
that requires a paclitaxel dose to be skipped, hold both pembrolizumab and paclitaxel 
until recovered, and reduce paclitaxel by one dose level on subsequent cycles.  
Pembrolizumab is not reduced. 
• For recurrent febrile neutropenia, and/or recurrent documented grade 4 neutropenia 
that requires a paclitaxel dose to be skipped (after initial paclitaxel dose reduction), a 
second paclitaxel dose reduction will be performed.  The investigator may, per their 
clinical assessment, add prophylactic growth factors (filgrastim) according to 
institutional standard). In this circumstance, it is recommended that filgrastim (dose 
according to institutional standard) will be administered daily subcutaneously starting 
24-72 hours after paclitaxel chemotherapy. Administration of filgrastim on the same 
day as chemotherapy is not allowed.  Pembrolizumab is not reduced. 
• There will be no dose modifications on the basis of uncomplicated granulocyte nadirs 
lasting less than 7 days.  Patients with grade 4 thrombocytopenia will have a 1 level 
dose reduction of paclitaxel.  Hold treatment up to 3 weeks until resolves to grade 0-1 
or baseline.  Recurrent grade 4 thrombocytopenia will lead to a second dose reduction 
of paclitaxel.  If not resolved within 3 weeks, patient should be taken off paclitaxel 
treatment and may continue pembrolizumab.  For recurrent grade 4 thrombocytopenia 
on pembrolizumab alone, discontinue all treatment and go onto study follow-up 
surveillance until progression. 
• Patients with grade 3 thrombocytopenia, hold up to 3 weeks until resolves to grade 0-
1 or baseline.  If not resolved within 3 weeks, patient should be taken off paclitaxel 
treatment and may continue pembrolizumab.  For recurrent grade 3 thrombocytopenia 
on pembrolizumab alone, discontinue all treatment and go onto study follow-up 
surveillance until progression. 
• Patients who are on study and develop thrombocytopenia may be transfused for any 
reason felt clinically indicated, including sustained tolerability of therapy, by their 
treating physicians. 
• Anemia (red blood cell) will not result in dose reductions.  Treatment should be by 
RBC transfusion only when symptomatic, clinically necessary, and with Hgb < 9.0. 
• Patients requiring greater than two dose reductions for any cause will result in 
removal of the agent that required 2 reductions.  If both agents have required >2 
reductions, the patient will go off study treatment and on to follow-up. 
Non-hematologic toxicity 
o Grade 2 (or greater) peripheral neuropathy requires reduction of one dose level for 
paclitaxel and delay in subsequent therapy for a maximum of 3 weeks until recovered 
to grade 1. If no recovery after 3 weeks, patient should be removed from study.  
Reoccurrence of grade 2 or greater requires a second paclitaxel dose reduction and a 
delay in subsequent therapy for a maximum of 3 weeks until recovered to grade 1. If 
no recovery after 3 weeks, patient should be removed from paclitaxel, but may 
continue pembrolizumab.   
• Grade 2 (or greater) renal toxicity requires reduction of one dose level for paclitaxel 
and delay in subsequent therapy for a maximum of 3 weeks until recovered to grade 
1. If no recovery after 3 weeks, patient should be off study treatment and on to

o Grade 3 (or greater) elevations in hepatic related tests: SGOT (AST), SGPT (ALT), 
alkaline phosphatase or bilirubin requires reduction of one dose level of paclitaxel, 
discontinuation of pembrolizumab, and a delay in subsequent therapy for a maximum 
of 3 weeks until recovered to grade 1. If no recovery after 3 weeks, patient should be 
removed from study. Reoccurrence of grade 2 or greater requires a second paclitaxel 
dose reduction and a delay in subsequent therapy for a maximum of 3 weeks until 
recovered to grade 1. If no recovery after 3 weeks, patient should be taken off study 
treatment and on to follow-up.  See also section 5.2.1.2, Table 3, on hepatic toxicity 
for pembrolizumab. 
o There will be no dose modifications for alopecia or fatigue.  
o For nausea, emesis, or diarrhea, please refer to section 5.6.1.  
o Non-hematologic toxicities with an impact on organ function of grade 2 (or 
greater) require reduction of one dose level of paclitaxel and delay in subsequent 
therapy for a maximum of 3 weeks until recovered to grade 1, or pre-therapy baseline. 
If no recovery after 3 weeks, patient should be taken off study treatment and on to 
follow-up. 
o Heart failure > grade 2 will result in removal from study. All other cardiac toxicity 
> grade 3 will result in removal from study. All other cardiac toxicity, grade 2, can 
result in delay of subsequent therapy for a maximum of two weeks and one level dose 
reduction of paclitaxel. Reoccurrence of any grade cardiac toxicity requires that 
patient should be removed from study. 
o Decrease of left ventricular ejection fraction (LVEF) to < 50 or decrease of LVEF by 
≥ 10% from baseline will result in removal from the study (grade 2 or greater, 
CTCAE v4, Investigations, Ejection fraction decreased).  
o Patients requiring greater than two dose reductions of both agents for any cause will 
result in removal from treatment and on to follow-up. 
o For pneumonitis and reactions that are thought to be immune-related: please 
refer to sections 5.6.1.1 and 5.6.1.2.  
o Patients with > grade 3 allergic reactions associated with pembrolizumab (MK-3475) 
will result in permanent discontinuation of pembrolizumab.  Paclitaxel may continue 
and patient followed for efficacy and toxicity. 
Infusion reactions 
o Table 5 (section 5.6.1) shows treatment guidelines for subjects who experience an 
infusion reaction associated with administration of pembrolizumab (MK-3475). 
o For paclitaxel related infusion reactions, please treat per institutional guidelines. 
Dose escalations  
o There will be no dose escalations or re-escalations on this study. 
 
5.2.2 Timing of Dose Administration 
Trial treatment should be administered on Day 1 of each cycle after all 
procedures/assessments have been completed as detailed on the Trial Flow Chart (Section 
6.0).  Trial treatment may be administered up to 3 days before or after the scheduled Day 1 of 
each cycle due to administrative reasons. 

Product:  Pembrolizumab (MK-3475)  
23 
Protocol/Amendment No.:  Version 4, November 21, 2017 
 
 
 
 
All trial treatments will be administered on an outpatient basis. 
Patients will given:  
 
• Paclitaxel 80 mg/m2 IV over 1 hour days 1, 8, 15 every 21 days. 
• Pembrolizumab (MK-3475) 200 mg IV over 30 minutes q 21 days (starting day 8 of 
cycle 1, then on day 1 of subsequent cycles).  
 
One cycle equals 21 days.  The first cycle is 28 days with Pembrolizumab given on day 8 in 
order to determine paclitaxel tolerance.  The inclusion of steroids during treatment with 
Pembrolizumab may decrease the efficacy of the agent. 
Pembrolizumab (MK-3475) will be administered as a 200 mg 30 minute IV infusion 
(treatment cycle intervals may be increased due to toxicity as described in Section 5.2.1.2).  
Sites should make every effort to target infusion timing to be as close to 30 minutes as 
possible. However, given the variability of infusion pumps from site to site, a window of -5 
minutes and +10 minutes is permitted (i.e., infusion time is 30 minutes: -5 min/+10 min). A 
Procedure Manual contains specific instructions for pembrolizumab (MK-3475) dose 
calculation, reconstitution, preparation of the infusion fluid, and administration. 
Paclitaxel will be administered as a 1 hour IV infusion on days 1, 8, 15 every 21 days, except 
cycle 1 where it will be administered on days 1, 8, 15, 21 of a 28 day cycle.  Sites should 
make every effort to target infusion timing to be as close to 60 minutes as possible.  
However, given the variability of infusion pumps from site to site, a window of -10 minutes 
and +20 minutes is permitted (i.e., infusion time is 60 minutes: -10 min/+20 min). 
• Specific Premedication Instructions: Given the immunotherapy mechanism of this 
trial, there are specific restrictions on the use of steroids.  A previous study of weekly 
paclitaxel examined eliminating steroids on subsequent infusions if no reaction 
occurred on the initial infusion (when steroids were given) [33]. Subsequent reactions 
in that setting were rare. Given that many reactions are possibly rate related, 
investigators should consider rate when considering management of treatment 
reactions. 
o For all cycles where paclitaxel is to be administered, it is recommended that a 
preparative regimen be employed, unless contraindicated, to reduce the risk 
associated with hypersensitivity reactions.  
o This regimen should include: 
i. An anti-histamine H1 blocker such as diphenhydramine 25-50 mg (or 
an equivalent 
dose 
of 
an 
alternate 
H1 
blocker 
such 
as 
chlorophineramine, loratadine or fexofenadine) IV or orally 30-60 
minutes before paclitaxel administration.  

Product:  Pembrolizumab (MK-3475)  
24 
Protocol/Amendment No.:  Version 4, November 21, 2017 
 
 
 
 
ii. An anti-histamine H2 blocker such as ranitidine 50 mg IV or 150 mg 
PO (or an equivalent dose of an alternate H2 blocker such as 
cimetidine, ranitidine, or famotidine) 30-60 minutes before paclitaxel 
administration. 
iii. On the first administration, a steroid such as dexamethasone 10 mg IV 
or PO should be given 30-60 minutes before paclitaxel. If no 
hypersensitivity reaction (HSR) to paclitaxel occurs, then subsequent 
weekly administrations should be attempted without steroids.   
iv. All HSRs may be managed with steroids or any other medications 
deemed medically necessary at the discretion of the investigator.  
However, given that many reactions are possibly rate related, 
investigators should consider rate when managing treatment reactions.  
Infusion times for paclitaxel may be extended up to 150 minutes after 
a suspected infusion reaction. 
v. If a HSR occurs, subsequent cycles may be premedicated with steroids 
as the investigator deems reasonable (the study chair may be consulted 
as desired). For pembrolizumab infusion reactions, please refer to 
5.6.1, Table 5.  The efficacy of pembrolizumab may be decreased in 
patients who receive steroids. 
If side effects are not severe, a patient may remain on study indefinitely until evidence of 
disease progression or unacceptable toxicity. 
5.2.3 Trial Blinding/Masking 
This is an open label non-randomized phase 2 trial; therefore, there will be no blinding. All 
patients will receive paclitaxel and pembrolizumab (MK-3475). 
5.3 
Registration 
Prior to enrollment, there should be documentation that verifies the following:  
• _All eligibility criteria have been met. 
• _There is a signed appropriate informed consent form and HIPAA authorization form.  
 
Patients registered at Moffitt will be registered by the Moffitt Study Coordinator. Patients 
placed on trial at affiliate sites will be registered through the Moffitt Clinical Research 
Network (MCRN). The MCRN Study Coordinator will perform the registration confirmation 
that will be sent back to the affiliate site.  
 
5.4 
Stratification 
There is no powered stratification for enrollment. Post hoc trial analyses will be done based 
upon prior number of treatments, treatment type, platinum free intervals, (0-3, 3-6 months), 

Product:  Pembrolizumab (MK-3475)  
25 
Protocol/Amendment No.:  Version 4, November 21, 2017 
 
 
 
 
whether steroids were given with a majority of cycles where Pembolizumab was given, and 
exploratory biomarkers (e.g. PD-L1 positivity).  
5.5 
Concomitant Medications/Vaccinations (allowed & prohibited) 
Medications or vaccinations specifically prohibited in the exclusion criteria are not allowed 
during the ongoing trial.  If there is a clinical indication for one of these or other medications 
or vaccinations specifically prohibited during the trial, discontinuation from trial therapy or 
vaccination may be required. The investigator should discuss any questions regarding this 
with the Sponsor. The final decision on any supportive therapy or vaccination rests with the 
investigator and/or the subject's primary physician. However, the decision to continue the 
subject on trial therapy or vaccination schedule requires the mutual agreement of the 
Investigator, the Sponsor, and the subject.  
5.5.1 Acceptable Concomitant Medications 
All treatments that the investigator considers necessary for a subject’s welfare may be 
administered at the discretion of the investigator in keeping with the community standards of 
medical care. All concomitant medication will be recorded on the case report form (CRF) 
including all prescription, over-the-counter (OTC), herbal supplements, and IV medications 
and fluids. If changes occur during the trial period, documentation of drug dosage, frequency, 
route, and date may also be included on the CRF. 
All concomitant medications received within 28 days before the first dose of trial treatment 
and 30 days after the last dose of trial treatment should be recorded. Concomitant 
medications administered after 30 days after the last dose of trial treatment should be 
recorded for SAEs and ECIs as defined in Section 7.2. 
5.5.2 Prohibited Concomitant Medications 
Subjects are prohibited from receiving the following therapies during the Screening and 
Treatment Phase (including retreatment for post-complete response relapse) of this trial: 
• Anti-cancer systemic chemotherapy or biological therapy  
• Immunotherapy not specified in this protocol 
• Chemotherapy not specified in this protocol 
• Investigational agents other than pembrolizumab (MK-3475) 
• Radiation therapy  
o Note:  Radiation therapy to a symptomatic solitary lesion or to the brain may 
be allowed after consultation with Sponsor.   
Live vaccines within 30 days prior to the first dose of trial treatment and while 
participating in the trial.  Examples of live vaccines include, but are not limited to, the 
following: measles, mumps, rubella, chicken pox, yellow fever, rabies, BCG, and typhoid 

Product:  Pembrolizumab (MK-3475)  
26 
Protocol/Amendment No.:  Version 4, November 21, 2017 
 
 
 
 
(oral) vaccine. Seasonal influenza vaccines for injection are generally killed virus 
vaccines and are allowed; however intranasal influenza vaccines (e.g. Flu-Mist®) are live 
attenuated vaccines, and are not allowed. 
• Glucocorticoids for any purpose other than to modulate symptoms from an event of 
clinical interest of suspected immunologic etiology.  The use of physiologic doses of 
corticosteroids may be approved after consultation with the Sponsor.  
Subjects who, in the assessment by the investigator, require the use of any of the 
aforementioned treatments for clinical management should be removed from the trial.  
Subjects may receive other medications that the investigator deems to be medically 
necessary. 
The Exclusion Criteria describes other medications which are prohibited in this trial. 
There are no prohibited therapies during the Post-Treatment Follow-up Phase. 
5.6 
Rescue Medications & Supportive Care 
5.6.1 Supportive Care Guidelines 
Subjects should receive appropriate supportive care measures as deemed necessary by the 
treating investigator.  Suggested supportive care measures for the management of adverse 
events with potential immunologic etiology are outlined below and in greater detail in the 
ECI guidance document. Where appropriate, these guidelines include the use of oral or 
intravenous treatment with corticosteroids as well as additional anti-inflammatory agents if 
symptoms do not improve with administration of corticosteroids.   Note that several courses 
of steroid tapering may be necessary as symptoms may worsen when the steroid dose is 
decreased. For each disorder, attempts should be made to rule out other causes such as 
metastatic disease or bacterial or viral infection, which might require additional supportive 
care. The treatment guidelines are intended to be applied when the investigator determines 
the events to be related to pembrolizumab.  
Note: if after the evaluation the event is determined not to be related, the investigator is 
instructed to follow the ECI reporting guidance but does not need to follow the treatment 
guidance (as outlined in the ECI guidance document). Refer to Section 5.2.1 for dose 
modification.  
It may be necessary to perform conditional procedures such as bronchoscopy, endoscopy, or 
skin photography as part of evaluation of the event. Suggested conditional procedures, as 
appropriate, can be found in the ECI guidance document. 
• Pneumonitis:  
o For Grade 2 events, treat with systemic corticosteroids. When symptoms 
improve to Grade 1 or less, steroid taper should be started and continued over 
no less than 4 weeks. 

Product:  Pembrolizumab (MK-3475)  
27 
Protocol/Amendment No.:  Version 4, November 21, 2017 
 
 
 
 
o For Grade 3-4 events, immediately treat with intravenous steroids.  
Administer additional anti-inflammatory measures, as needed. 
o Add prophylactic antibiotics for opportunistic infections in the case of 
prolonged steroid administration. 
 
• Diarrhea/Colitis:  
Subjects should be carefully monitored for signs and symptoms of enterocolitis (such 
as diarrhea, abdominal pain, blood or mucus in stool, with or without fever) and of 
bowel perforation (such as peritoneal signs and ileus).   
 
o All subjects who experience diarrhea/colitis should be advised to drink liberal 
quantities of clear fluids.  If sufficient oral fluid intake is not feasible, fluid 
and electrolytes should be substituted via IV infusion.  For Grade 2 or higher 
diarrhea, consider GI consultation and endoscopy to confirm or rule out 
colitis. 
o For Grade 2 diarrhea/colitis that persists greater than 3 days, administer oral 
corticosteroids.  
o For Grade 3 or 4 diarrhea/colitis that persists > 1 week, treat with 
intravenous steroids followed by high dose oral steroids.   
o When symptoms improve to Grade 1 or less, steroid taper should be started 
and continued over no less than 4 weeks. 
 
 
• Type 1 diabetes mellitus (if new onset, including diabetic ketoacidosis [DKA]) or 
≥ Grade 3 Hyperglycemia, if associated with ketosis (ketonuria) or metabolic 
acidosis (DKA) 
 
o For T1DM or Grade 3-4 Hyperglycemia 
 Insulin replacement therapy is recommended for Type I diabetes 
mellitus and for Grade 3-4 hyperglycemia associated with metabolic 
acidosis or ketonuria.  
 Evaluate patients with serum glucose and a metabolic panel, urine 
ketones, glycosylated hemoglobin, and C-peptide.  
 
• Hypophysitis: 
 
 Grade 2-4 events: 
 Report as ECI if appropriate 
 Hold pembrolizumab 
 Rule out infection and sepsis with appropriate cultures and imaging. 
 Monitor thyroid function or other hormonal level tests and serum 
chemistries more frequently until returned to baseline values. 
 Pituitary gland imaging should be considered (MRIs with gadolinium and 
selective cuts of the pituitary can show enlargement or heterogeneity and 
confirm the diagnosis). 

Product:  Pembrolizumab (MK-3475)  
28 
Protocol/Amendment No.:  Version 4, November 21, 2017 
 
 
 
 
 Treat with prednisone 40 mg p.o. or equivalent per day. When symptoms 
improve to Grade 1 or less, steroid taper should be started and continued 
over no less than 4 weeks. 
 Replacement of appropriate hormones may be required as the steroid dose 
is tapered. 
 Permanently discontinue for inability to reduce corticosteroid dose to 10 
mg or less of prednisone or equivalent per day within 12 weeks. 
 Hypophysitis with clinically significant adrenal insufficiency and 
hypotension, dehydration, and electrolyte abnormalities (such as 
hyponatremia and hyperkalemia) constitutes adrenal crisis.  
 Consultation with an endocrinologist may be considered. 
 
 
 
• Hyperthyroidism or Hypothyroidism:  
Thyroid disorders can occur at any time during treatment. Monitor patients for 
changes in thyroid function (at the start of treatment, periodically during treatment, 
and as indicated based on clinical evaluation) and for clinical signs and symptoms of 
thyroid disorders. 
 
o Grade 2 hyperthyroidism events (and Grade 3-4 hypothyroidism): 
 In hyperthyroidism, non-selective beta-blockers (e.g. propranolol) are 
suggested as initial therapy. 
 In hypothyroidism, thyroid hormone replacement therapy, with 
levothyroxine or liothyroinine, is indicated per standard of care. 
o Grade 3-4 hyperthyroidism  
 Treat with an initial dose of IV corticosteroid followed by oral 
corticosteroids. When symptoms improve to Grade 1 or less, steroid 
taper should be started and continued over no less than 4 weeks. 
Replacement of appropriate hormones may be required as the steroid 
dose is tapered. 
 
• Hepatic: 
o For Grade 2 events, monitor liver function tests more frequently until 
returned to baseline values (consider weekly). 
 Treat with IV or oral corticosteroids 
o For Grade 3-4 events, treat with intravenous corticosteroids for 24 to 48 
hours.  
o When symptoms improve to Grade 1 or less, a steroid taper should be started 
and continued over no less than 4 weeks. 
 
• Renal Failure or Nephritis: 
o For Grade 2 events, treat with corticosteroids.

Protocol/Amendment No.:  Version 4, November 21, 2017 
 
 
 
 
o For Grade 3-4 events, treat with systemic corticosteroids. 
o When symptoms improve to Grade 1 or less, steroid taper should be started and 
continued over no less than 4 weeks.  
 
• Management of Infusion Reactions: Signs and symptoms usually develop during or 
shortly after drug infusion and generally resolve completely within 24 hours of 
completion of infusion.

consideration should be given in subsequent cycles to the administration of 
prophylactic antiemetic therapy according to standard institutional practice.  Subjects 
should be strongly encouraged to maintain liberal oral fluid intake. 
• Anti-infectives: Subjects with a documented infectious complication should receive 
oral or IV antibiotics or other anti-infective agents as considered appropriate by the 
treating investigator for a given infectious condition, according to standard 
institutional practice. 
• GCSF – Filgrastim and Pegfilgrastim. Pegfilgrastim is not allowed. The use of 
filgrastim has limitations (see section 5.2.2) and should be used only when deemed to 
be absolutely necessary by the treating investigator.  See hematologic toxicity section 
5.2.1.2.   
• IMMUNE-RELATED ADVERSE EVENTS: Please see Section 5.6.1.1 below and

CLINICAL 
INTEREST 
AND

ADVERSE 
EVENT 
GUIDANCE DOCUMENT, Version 5.0) regarding diagnosis and management of 
adverse experiences of a potential immunologic etiology.   
5.6.1.1 Supportive Care Guidelines for Immune-Related Events of Clinical 
Interest (irECIs) and Immune-related Adverse Events (irAEs) 
Please reference version 3 of the irAE guidance document “Pembrolizumab Event of Clinical 
Interest Guidance Document” that will accompany this protocol. 
Events of clinical interest of a potential immunologic etiology (irECIs) may be defined as an 
adverse event of unknown etiology, associated with drug exposure and is consistent with an 
immune phenomenon. Immune-related adverse events (irAEs) may be predicted based on the 
nature of the pembrolizumab (MK-3475) compound, its mechanism of action, and reported 
experience with immunotherapies that have a similar mechanism of action. Special attention 
should be paid to AEs that may be suggestive of potential irAEs.  An irAE can occur shortly 
after the first dose or several months after the last dose of treatment.   

Product:  Pembrolizumab (MK-3475)  
31 
Protocol/Amendment No.:  Version 4, November 21, 2017 
 
 
 
 
If an irAE is suspected, efforts should be made to rule out neoplastic, infectious, metabolic, 
toxin or other etiologic causes prior to labeling an adverse event as an irAE.  Information on 
how to identify and evaluate irAEs has been developed and is included in the Event of 
Clinical Interest and Immune-Related Adverse Event Guidance Document.  .  Based on these 
potential irAEs, the sponsor has defined a list of specific adverse event terms (ECIs) that are 
selected adverse experiences that must be reported to Merck within 24 hours from the 
time the Investigator/physician is aware of such an occurrence, regardless of whether or not 
the investigator/physician considers the event to be related to study drug(s). In addition, these 
ECIs require additional detailed information to be collected and entered in the study 
database.  ECIs may be identified through spontaneous patient report and / or upon review of 
subject data. Table 1 provides the list of terms and reporting requirements for AEs that must 
be reported as ECIs for MK-3475 protocols.  Of note, the requirement for reporting of ECIs 
applies to all arms, including comparators, of MK-3475 clinical trials  
 
Given that our current list of events of clinical interest is not comprehensive for all potential 
immune-related events, it is possible that AEs other than those listed in this document may be 
observed in patients receiving pembrolizumab. Therefore any Grade 3 or higher event that 
the investigator/physician considers to be immune-related should be reported as an ECI 
regardless of whether the specific event term is in Table 1 and reported to Merck within 24 
hours from the time the Investigator/physician is aware of such an occurrence.  Adverse 
events that are both an SAE and an ECI should be reported one time as an SAE only, 
however the event must be appropriately identified as an ECI as well in in the database. 
The guidelines for handling Pneumonitis are in section 5.6.1.2 below.  Others such as Colitis, 
Endocrine, Hematologic, Hepatic, Neurologic, Ocular, Renal, Skin are listed in the ECI. 
The following AEs, regardless of grade, are considered ECIs and should be reported to the 
Sponsor within 24 hours of the event: 
– Myocarditis 
– Pericarditis 
– Pancreatitis 
– Any additional Grade 3 or higher event which the physician considers to be immune 
related 
 
All attempts should be made to rule out other causes.  Therapeutic specialists should be 
consulted as appropriate. However the AE should be reported regardless of etiology. 
Recommendations to managing irAEs not detailed elsewhere in the protocol or ECI are 
detailed in Table 6.

5.7 
Diet/Activity/Other Considerations 
5.7.1 Diet 
Subjects should maintain a normal diet unless modifications are required to manage an AE 
such as diarrhea, nausea or vomiting. 
5.7.2 Contraception 
Pembrolizumab (MK-3475) may have adverse effects on a fetus in utero. Furthermore, it is 
not known if pembrolizumab (MK-3475) has transient adverse effects on the composition of 
sperm.  Non-pregnant, non-breast-feeding women may be enrolled if they are willing to use 2 
methods of birth control or are considered highly unlikely to conceive. Highly unlikely to 
conceive is defined as 1) surgically sterilized, or 2) postmenopausal (a woman who is ≥45 
years of age and has not had menses for greater than 1 year will be considered 
postmenopausal), or 3) not heterosexually active for the duration of the study.  The two birth 
control methods can be either two barrier methods or a barrier method plus a hormonal 
method to prevent pregnancy. Subjects should start using birth control from study Visit 1 
throughout the study period up to 120 days after the last dose of study therapy.  
The following are considered adequate barrier methods of contraception: diaphragm, condom 
(by the partner), copper intrauterine device, sponge, or spermicide. Appropriate hormonal 
contraceptives will include any registered and marketed contraceptive agent that contains an 
estrogen and/or a progestational agent (including oral, subcutaneous, intrauterine, or 
intramuscular agents). 
Subjects should be informed that taking the study medication may involve unknown risks to 
the fetus (unborn baby) if pregnancy were to occur during the study. In order to participate in 
the study they must adhere to the contraception requirement (described above) for the 
duration of the study and during the follow-up period defined in section 7.2.2-Reporting of 
Pregnancy and Lactation to the Sponsor and to Merck.  If there is any question that a subject 
will not reliably comply with the requirements for contraception, that subject should not be 
entered into the study. 
5.7.3 Use in Pregnancy 
If a subject inadvertently becomes pregnant while on treatment with pembrolizumab (MK-
3475), the subject will immediately be removed from the study.  The site will contact the 

Product:  Pembrolizumab (MK-3475)  
35 
Protocol/Amendment No.:  Version 4, November 21, 2017 
 
 
 
 
subject at least monthly and document the subject’s status until the pregnancy has been 
completed or terminated. The outcome of the pregnancy will be reported to the Sponsor and 
to Merck without delay and within 24 hours if the outcome is a serious adverse experience 
(e.g., death, abortion, congenital anomaly, or other disabling or life-threatening complication 
to the mother or newborn). The study investigator will make every effort to obtain 
permission to follow the outcome of the pregnancy and report the condition of the fetus or 
newborn to the Sponsor.  
5.7.4 Use in Nursing Women 
It is unknown whether pembrolizumab (MK-3475) is excreted in human milk.  Since many 
drugs are excreted in human milk, and because of the potential for serious adverse reactions 
in the nursing infant, subjects who are breast-feeding are not eligible for enrollment. 
5.8 
Subject Withdrawal/Discontinuation Criteria 
Subjects may withdraw consent at any time for any reason or be dropped from the trial at the 
discretion of the investigator should any untoward effect occur. In addition, a subject may be 
withdrawn by the investigator or the Sponsor if enrollment into the trial is inappropriate, the 
trial plan is violated, or for administrative and/or other safety reasons. Specific details 
regarding discontinuation or withdrawal are provided in Section 7. 
A subject must be discontinued from the trial for any of the following reasons: 
• The subject withdraws consent. 
• Radiographic disease progression 
Note: A subject may be granted an exception to continue on treatment with 
radiographic progression if clinically stable or clinically improved after 
consultation with the study PI and consultation with Merck. 
• Unacceptable adverse events.  
• Intercurrent illness that likely prevents further administration of treatment 
• Investigator’s decision to withdraw the subject 
• The subject has a confirmed positive serum pregnancy test 
• Noncompliance with trial treatment or procedure requirements 
• The subject is lost to follow-up 
• Completed 24 months of treatment with pembrolizumab (MK-3475) 

Product:  Pembrolizumab (MK-3475)  
36 
Protocol/Amendment No.:  Version 4, November 21, 2017 
 
 
 
 
Note: 24 months of study medication is calculated from the date of first dose. Subjects 
who stop pembrolizumab (MK-3475) after 24 months may be eligible for up to one 
year of additional study treatment if they progress after stopping study treatment 
provided they have a PS >2, have not had initiation of a new regimen nor had 
discontinuation due to toxicity.  This must be approved by the study PI in consultation 
with Merck.  
• Administrative reasons 
The End of Treatment and Follow-up visit procedures are listed in Section 6 (Protocol Flow 
Chart) and Section 7.1.5 (Visit Requirements).  After the end of treatment, each subject will 
be followed for 30 days for adverse event monitoring (serious adverse events will be 
collected for 90 days after the end of treatment (or until new treatment started) as described 
in Section 7.2.3.1). Subjects who discontinue for reasons other than progressive disease will 
have post-treatment follow-up for disease status until disease progression, initiating a non-
study cancer treatment, withdrawing consent or becoming lost to follow-up. After 
documented disease progression each subject will be followed by telephone for overall 
survival until death, withdrawal of consent, or the end of the study, whichever occurs first. 
5.9 
Subject Replacement Strategy 
In the event a patient is deemed ineligible or is not assessable for the primary endpoint 
assessment, the patient may be replaced at the discretion of the study PI in consultation. 
5.10 Clinical Criteria for Early Trial Termination 
Early trial termination will be the result of the criteria specified below: 
1. Quality or quantity of data recording is inaccurate or incomplete 
2. Poor adherence to protocol and regulatory requirements 
3. Incidence or severity of adverse drug reaction in this or other studies indicates a potential 
health hazard to subjects 
4. Plans to modify or discontinue the development of the study drug 
In the event of Merck decision to no longer supply study drug, ample notification will be 
provided so that appropriate adjustments to subject treatment can be made.

All assessments obtained should be made using the same type of study (e.g. spiral CT Scan) as was used at baseline.  Scans should be done during the 7 
days prior to, or on the day of, the next due cycle.  For example first scan is during the week before or on day of cycle 4, day 1.  Scan must be 
interpreted for disease response prior to administering cycle.   Scan dates should be recorded.  If a treatment has to be delayed and patient has already 
had a scan, it is not necessary to repeat the scan prior to next dosing due to the delay (it will not be out of window).

13 
Cycle length is 21 days (except cycle 1 of 28 days).  The first dose of pembrolizumab is on cycle 1 day 8, then day 1 of subsequent cycles. 
14 
Trial treatment should be administered on Day 1 of each cycle after all procedures/assessments have been completed as detailed on the Trial Flow Chart 
above (Section 6.0).  Trial treatment may be administered up to 3 days before or after the scheduled Day 1 of each cycle due to administrative 
reasons.All trial treatments will be administered on an outpatient basis.  Patients will be given: 
• 
Paclitaxel 80 mg/m2 IV over 1 hour days 1, 8, 15 every 21 days.  First cycle has days 1, 8, 15, 21 of a 28 day cycle. 
• 
Pembrolizumab (MK-3475) 200 mg IV over 30 minutes q 21 days (starting day 8 of cycle 1, then on day 1 of subsequent cycles).  
One cycle equals 21 days.  The first cycle is 28 days with Pembrolizumab given on day 8 in order to determine paclitaxel tolerance.  The inclusion of 
steroids during treatment with Pembrolizumab may decrease the efficacy of the agent.

7.0 TRIAL PROCEDURES 
The Trial Flow Chart - Section 6.0 summarizes the trial procedures to be performed at each 
visit. Individual trial procedures are described in detail below. It may be necessary to perform 
these procedures at unscheduled time points if deemed clinically necessary by the 
investigator. 
Furthermore, additional evaluations/testing may be deemed necessary by the Sponsor and/or 
Merck for reasons related to subject safety. In some cases, such evaluation/testing may be 
potentially sensitive in nature (e.g., HIV, Hepatitis C, etc.), and thus local regulations may 
require that additional informed consent be obtained from the subject.  In these cases, such 
evaluations/testing will be performed in accordance with those regulations. 
7.1 
Administrative Procedures 
7.1.1 Informed Consent 
The Investigator must obtain documented consent from each potential subject prior to 
participating in a clinical trial. 
7.1.1.1 General Informed Consent 
Consent must be documented by the subject’s dated signature or by the subject’s legally 
acceptable representative’s dated signature on a consent form along with the dated signature 
of the person conducting the consent discussion.  
A copy of the signed and dated consent form should be given to the subject before 
participation in the trial. 
The initial informed consent form, any subsequent revised written informed consent form 
and any written information provided to the subject must receive the IRB/ERC’s 
approval/favorable opinion in advance of use. The subject or his/her legally acceptable 
representative should be informed in a timely manner if new information becomes available 
that may be relevant to the subject’s willingness to continue participation in the trial. The 
communication of this information will be provided and documented via a revised consent 
form or addendum to the original consent form that captures the subject’s dated signature or 
by the subject’s legally acceptable representative’s dated signature. 
Specifics about a trial and the trial population will be added to the consent form template at 
the protocol level.   
The informed consent will adhere to IRB/ERC requirements, applicable laws and regulations 
and Sponsor requirements.

7.1.1.2 Inclusion/Exclusion Criteria 
All inclusion and exclusion criteria will be reviewed by the investigator or qualified designee 
to ensure that the subject qualifies for the trial.  
7.1.1.3 Subject Identification Card 
All subjects will be given a Subject Identification Card identifying them as participants in a 
research trial. The card will contain trial site contact information (including direct telephone 
numbers) to be utilized in the event of an emergency.  The study site investigator or qualified 
designee will provide the subject with an IRB approved Subject Identification Card after the 
subject provides written informed consent. 
7.1.1.4 Medical History 
A medical history will be obtained by the investigator or qualified designee. Medical history 
will include all active conditions, and any condition diagnosed within the prior 10 years that 
are considered to be clinically significant by the Investigator. Details regarding the disease 
for which the subject has enrolled in this study will be recorded separately and not listed as 
medical history.   
7.1.1.5 Prior and Concomitant Medications Review 
7.1.1.5.1 Prior Medications 
The investigator or qualified designee will review prior medication use, including any 
protocol-specified washout requirement, and record prior medication taken by the subject 
within 28 days before starting the trial. Treatment for the disease for which the subject has 
enrolled in this study will be recorded separately and not listed as a prior medication.  
7.1.1.5.2 Concomitant Medications 
The investigator or qualified designee will record medication, if any, taken by the subject 
during the trial.  All medications related to reportable SAEs and ECIs should be recorded as 
defined in Section 7.2. 
7.1.1.6 Disease Details and Prior Treatments 
7.1.1.6.1 Disease Details 
The investigator or qualified designee will obtain prior and current details regarding disease 
status.  
7.1.1.6.2 Prior Treatment Details 
The investigator or qualified designee will review all prior cancer treatments including 
systemic treatments, radiation and surgeries.

7.1.1.6.3 Subsequent Anti-Cancer Therapy Status 
The investigator or qualified designee will review all new anti-neoplastic therapy initiated 
after the last dose of trial treatment. If a subject initiates a new anti-cancer therapy within 30 
days after the last dose of trial treatment, the 30 day Safety Follow-up visit must occur before 
the first dose of the new therapy. Once new anti-cancer therapy has been initiated the subject 
will move into survival follow-up.  
7.1.1.7 Registration Procedures for Affiliate Sites 
All subjects at affiliate sites must be registered with the MCRN Coordinating Center to be 
able to participate in t h e  trial. The participating site must fax or email the completed 
study specific eligibility checklist and registration forms, supporting documents and 
signature page of the informed consent to the Coordinating Center. Unsigned or 
incomplete forms will be returned to the site. Once documents are received, the MCRN 
Research Coordinator will review them to confirm eligibility and to complete the 
registration process. If eligibility cannot be confirmed, the research coordinator will 
query the site for clarification or additional documents as needed. Subjects failing to 
meet all study eligibility requirements will not be registered and will be unable to 
participate in the trial. 
 
Upon completion of registration, the MCRN Research Coordinator will provide the 
participating site with the study sequence number. Within 24-48 hours after 
registration, it is the site’s responsibility to: 
• Enter the demographic and on-study patient information into the Oncore 
database 
• Order investigational agent(s) if indicated per protocol 
 
It is the responsibility of the participating Investigator or designee to inform the 
subject of the research treatment plan and to conduct the study in compliance with 
the protocol as agreed upon with Moffitt Cancer Center and approved by the site’s 
IRB. 
To register a patient send the completed signed eligibility checklist along with 
supporting documentation to the MCRN via email at affiliate.research@moffitt.org or 
via fax at 813-745-5666, Monday through Friday between 8:00AM and 5:00PM (EST). 
 
7.1.2 Clinical Procedures/Assessments 
7.1.2.1 Adverse Event (AE) Monitoring 
All patients who receive at least 1 dose of study treatment with paclitaxel will be evaluated 
for safety parameters. AEs will be collected from the start of treatment until off trial.

Confidential  Limited Access 
 
The investigator or qualified designee will assess each subject to evaluate for potential new 
or worsening AEs as specified in the Trial Flow Chart and more frequently if clinically 
indicated.  Adverse experiences will be graded and recorded throughout the study and during 
the follow-up period according to NCI CTCAE Version 4.0 (see Section 12.2).  Toxicities 
will be characterized in terms regarding seriousness, causality, toxicity grading, and action 
taken with regard to trial treatment.  
All AEs of unknown etiology associated with pembrolizumab (MK-3475) exposure should 
be evaluated to determine if it is possibly an event of clinical interest (ECI) of a potentially 
immunologic etiology (irAE). See Section 5.6.1.1 and the separate guidance document 
regarding the identification, evaluation and management of AEs of a potential immunological 
etiology.   
Please refer to section 7.2 for detailed information regarding the assessment and recording of 
AEs.   
7.1.2.2 Directed Physical Exams 
The investigator or qualified designee will perform a complete physical exam during the 
screening period. Clinically significant abnormal findings should be recorded as medical 
history.  A full physical exam should be performed during screening. The investigator or 
qualified designee will also perform a directed physical exam as clinically indicated prior to 
each treatment cycle administration.   
7.1.2.3 Vital Signs 
The investigator or qualified designee will take vital signs at screening, prior to the 
administration of each dose of trial treatment and at treatment discontinuation as specified in 
the Trial Flow Chart (Section 6.0).  Vital signs should include temperature, pulse, respiratory 
rate, weight and blood pressure.  Height will be measured at screening only. 
7.1.2.4 Eastern Cooperative Oncology Group (ECOG) Performance Scale 
The investigator or qualified designee will assess ECOG status (see Section 12.1) at 
screening, prior to the administration of each dose of trial treatment and discontinuation of 
trial treatment as specified in the Trial Flow Chart. After Cycle 8, assessment of ECOG 
status will be performed every other cycle in conjunction with the physical exam. 
7.1.2.5 Tumor Imaging and Assessment of Disease 
7.1.2.5.1 General requirements regarding imaging and CA-125 
All patients with measurable disease will be assessed by RECIST v1.1, and irRC criteria. 
All patients with elevated CA125 elevated at least 2xULN at baseline and EITHER 
malignant pleural effusion or ascites OR radiographic evidence of disease that is non-
measureable, will be assessed by a combination of radiographic findings (RECIST v1.1) 
and Rustin criteria.

Protocol/Amendment No.:  Version 3.0, September 12, 2016

In ovarian cancer, RECIST v1.1 and CA125 have been used to measure response and 
document progression.  Progression will only be confirmed to occur in the event of 
RECIST findings of progression. CA-125 will not be used by itself for progression.  
Notation should be made on tumor assessment (TA) times, however, if the CA-125 has 
doubled from a nadir value during the course of treatment.   
 
The TA performed during screening will be used as a baseline for efficacy assessments. 
Contrasted CT (or MRI) imaging of the chest and abdomen and pelvis is required at 
screening and at each TA, regardless of the location of known metastases. In addition, 
scans must be obtained of anatomic regions not covered by the chest and abdomen 
scans in subjects where there is clinical suspicion of metastases. Such additional 
CT/MRIs will be required at screening when a non-abdominopelvic or chest lesion is 
known/suspected and must be consistently repeated at all TAs if identified during 
Screening. The same imaging modality must be used for all TAs, unless contraindicated.  
 
Imaging-based evaluation is preferred to clinical examination. Helical (spiral) CT scans 
of the chest, abdomen, and pelvis are preferred. If not available, conventional 
(nonhelical, nonspiral CT) may be used; however, a measurable lesion must not have 
the longest diameter smaller than 20 mm by conventional CT or MRI (10 mm on spiral 
CT). Oral and IV contrast should be used for all CT scans; if IV contrast is 
contraindicated, oral contrast alone may be used, or MRI should be used. Subjects who 
develop oral and IV contrast allergy after study enrollment, or whose tumor is not 
measurable with the elimination of one form of contrast, must be followed by MRI for 
subsequent tumor measurements. 
 
A reference measurement ruler must be printed on every image for scale 
determination. Sections should be contiguous, similarly sized and consistent from visit-
to-visit. Section thickness must be based on institutional standards (e.g., from 3 to 8 
mm, 10 mm cuts are not sufficient). Chest x-rays and ultrasound are not acceptable 
methods to measure disease.  
 
New fluid findings such as pleural effusion or ascites will not constitute progression by 
themselves. Skin and soft tissue lesions will be captured as non-measurable lesions 
through physical examination only. 
 
Any subject who develops an objective tumor response (CR or PR) or progression (PD) 
is required to undergo confirmatory scans no less than 4 weeks since the prior scan in 
order to verify the reliability of the radiologic finding. Sites are encouraged to collect 
additional CT scans after RECIST v1.1 PD has been confirmed, as long as a subsequent 
line of therapy has not been initiated.

7.1.2.5.2 Response Evaluation Criteria in Solid Tumors (RECIST) 
v1.1 (for irRECIST see appendix 12.5) 
Response and disease progression will be evaluated using the modified international 
criteria proposed by the RECIST v1.1 committee. Changes only in the largest diameter 
(unidirectional measurement) of the tumor lesions are used in the RECIST v1.1 criteria.  
For tumor lymph nodes, the short axis must be measured. Lesions are measurable or 
non-measurable using the definitions described below. 
Definition of Measurable / Non-Measurable Disease 
o Measurable disease is present if the subject has one or more measurable lesions. 
(Note: If the measurable disease is confined to a solitary lesion, its neoplastic 
nature should be confirmed by histology or cytology). An exception would be the 
new appearance of a measurable target lesion and a CA-125 indicative of 
progression (doubling of the nadir value and with a confirmation of same as per 
CA-125 criteria (see section 7.1.2.5.1). Disease in a previously irradiated field is 
acceptable as the only site of measurable disease only if there has been clear 
progression since completion of radiotherapy. 
o Measurable lesions are those that can be accurately measured in at least one 
dimension, in accordance with the following criteria: if conventional technique 
CT, MRI, x-ray (for non-spiral or non-helical) the longest diameter of at least one 
lesion to be recorded must have a diameter ≥ 20 mm. If Spiral (Helical) CT is 
used at least 1 diameter should be ≥ 10 mm, assuming the images were 
performed using a 5-mm contiguous reconstruction algorithm (interval). If a 5-
mm contiguous reconstruction algorithm (interval) is not used, as a general rule, 
the lesion diameter should be no less than double the reconstruction algorithm 
(interval). In all instances, Spiral CT is preferred if available. All tumor 
measurements must be recorded in millimeters. 
o Non-measurable lesions/disease are all other lesions (or sites of disease), 
including small lesions (those with all measurements < 20 mm when the subject 
is evaluated with conventional (non-spiral/non-helical CT; MRI or x-ray; or < 10 
mm with Spiral CT as described above), and any of the following: 
o Primary breast lesions assessed by physical exam only, bone lesions, 
ascites, pleural or pericardial effusion, inflammatory breast disease, 
lymphangitis cutis/pulmonis, abdominal masses that are not confirmed 
and followed by imaging techniques, cystic lesions, and lesions occurring 
within a previously irradiated area unless they are documented as new 
lesions since the completion of radiation therapy. 
o  
7.1.2.5.3 Method of Tumor Response Assessment 
Baseline measurements should be done within 4 weeks before the beginning of the 
treatment. For target lesions, largest and/or most reproducible lesions (large or small) 
must be selected. Tumor lesions situated in previously irradiated areas will not be 
considered measurable unless disease in a previously irradiated field is the only site of 
measurable disease and there has been clear progression since completion of

radiotherapy. The same method of assessment should be used to identify and report 
each lesion at baseline and at re-assessment during treatment. Imaging based 
evaluation is preferred to clinical examination. 
 
CT and MRI are considered to be the best currently available and reproducible methods 
to measure target lesions selected for response assessment. Conventional CT and MRI 
should be performed with contiguous cuts of 10 mm or less thickness contiguously. 
Spiral CT should be performed using a 5 mm contiguous reconstruction algorithm. 
Lesions on chest x-ray are acceptable as measurable lesions when they are clearly 
defined and surrounded by aerated lung; however, CT is preferable. 
 
Clinically detected lesions will only be considered measurable when they are superficial 
(e.g., skin nodules and palpable lymph nodes). For skin lesion documentation by color 
photography, including ruler to measure size of lesions is recommended. 
 
Ultrasound and/or physical exam will not be allowed as the only procedure to evaluate 
tumor lesions, except for superficial lymph nodes and subcutaneous lesions. 
 
In addition, ultrasound and physical examination together may be used to confirm 
complete disappearance of superficial lesions (Target or non-target). 
 
7.1.2.5.4 Definition of Target versus Non-Target Lesions 
When more than one measurable lesions is present at baseline, all lesions up to a 
maximum of five lesions total (and a maximum of two lesions per organ) representative 
of all involved organs should be identified as target lesions and will be recorded and 
measured at baseline (this means in instances where subjects have only one or two 
organ sites involved a maximum of two and four lesions respectively will be recorded). 
In addition, target lesions should be selected based on their size (lesions with the 
largest area and/or longest diameter), be representative of all involved organs, and in 
addition should be those that lend themselves to reproducible repeated measurements.  
 
At baseline, the longest diameters for all non-nodal target lesions and the short axis for 
all nodal target lesions will be added and considered the baseline sum of diameters. The 
baseline sum will be used as the reference point to determine the objective tumor 
response of the target lesions. Lymph nodes with tumor burden will be considered as 
target lesions if the short axis is ≥ 15 mm. (The short axis is measurement 
perpendicular to longest measurement of the node assed in plane of measurement). 
Measurable lesions other than the target lesions, and all sites of non-measurable 
disease, will be identified as non-target lesions. Lymph nodes will be considered as non-
target lesions if the short axis is ≥ 10 mm and < 15 mm and considered as normal if the 
short axis is < 10 mm. Repeat measurements of non-target lesions is not required but 
presence or absence of these lesions should be noted throughout the tumor re-
assessments. Non-target lesions will be recorded on the CRFs and should be evaluated

at the same assessment time points as all target lesions. All lesions must be followed for 
response and progression. In subsequent assessments, non-target lesions will be 
recorded as either:” present,” “absent” or “unequivocal progression. 
 
7.1.2.5.5 Definition of Response 
Overall tumor response will be based on an integration of the evaluation of target, non-
target and new lesions, as described below: 
  
Evaluation of Target Lesions 
o Complete Response (CR): Disappearance of all clinical and radiological evidence 
of target lesions. When lymph nodes are included as target and non-target 
lesions complete response per lymph node will be achieved with short axis of all 
nodes measuring < 10 mm and the disappearance of all clinical and/or 
radiological evidence of lymph nodes is not required. 
o Partial Response (PR): At least 30% reduction in the sum of longest diameter of 
all lesions; taking as reference the baseline study measurement.  
o Progressive Disease (PD): Requires that there is a 20% or greater increase in the 
sum of longest diameter of all target lesions AND an absolute increase of at least 
5 mm of tumor size, taking as reference the smallest sum of the longest diameter 
recorded at or following baseline or the appearance of one or more new lesions. 
o Stable Disease (SD): Neither PR or PD are met, taking as reference the smallest 
sum of the longest diameter recorded at baseline. 
 
Evaluation of Non-Target Lesions 
All other lesions (or sites of disease) not included in the “target lesions” 
definition should be identified as non-target lesions and should also be recorded 
at baseline. Measurements are not required and these lesions should be followed 
as “present” or “absent” or “unequivocal progression”. Tumor within a 
previously irradiated field will be designated as “non-target” lesions unless 
progression is documented or a biopsy is obtained to confirm persistence at 
least 90 days following completion of radiation therapy. 
o Complete Response (CR): Disappearance of all non-target lesions and 
normalization of tumor marker level. If tumor markers are initially above the 
upper normal limit, they must normalize for a subject to be considered in 
complete clinical response. 
o Non-Complete 
Response, 
Non-Progressive 
Disease 
(Non-CR, 
Non-PD): 
Persistence of one or more non-target lesions and/or maintenance of tumor 
markers level above the upper limits of normal. 
o Progressive Disease (PR): Unequivocal progression of existing non-target 
lesion(s) (note: the appearance of one or more new lesions is also considered as 
progression.) 
Evaluation of new lesions 
o No: There are no new lesions. 
o Yes: New lesions are present. If new lesions are present, the subject is

Protocol/Amendment No.:  Version 3.0, September 12, 2016

considered to have progressive disease overall. 
Notes: 
o Unequivocal progression of non-target lesions implies that the subject has 
progressive disease overall at that time point and must stop study treatment. 
Increase in radiotracer uptake on bone scan alone is insufficient evidence of 
progression; additional evidence of progressive disease should be present to 
declare unequivocal progression. An increase in ascites or effusion alone is 
insufficient evidence of progression; an additional evidence of progression 
should be present to declare unequivocal progression.  If a scan shows new 
lesion(s) in an anatomical region which was not included in the baseline scans it 
is still PD. 
o FDG-PET may be used if deemed necessary from an unusual but necessary 
clinical perspective.  The study chair should be consulted when possible.  It 
should not replace standard imaging by RECIST, but may at times complement.  
Investigators should work with the study chair when interpreting these in the 
context of response or progression.  
 
 
 
7.1.2.5.6 Evaluation of Best Overall Response  
Best overall response is the best response recorded from the start of 
treatment until disease progression or recurrence (taking as reference 
the smallest measurement recorded since the start of treatment) and will 
be determined as tabulated below, based on evaluation of target, non-
target and new lesions. 
 
7.1.2.6 Tumor Tissue Collection and Correlative Studies Blood Sampling 
• 5 paraffin 5-micron unstained slides (“TUS”), or equivalent block (tissue block “TB”) 
to make these, available from initial diagnosis or subsequent recurrence. Notation of 
relationship to prior treatment should be made (List treatment regimens used prior to 
acquisition of the tissue in the slides or block, the most recent treatment regimen and 
number of cycles, last treatment date prior to tissue acquisition, date of tissue 
acquisition). Directions and kits for processing will be done via Qualtek.  An 
appendix Sample Handling Manual is provided.  Confirmation of availability of 
getting tissue slides or block should be made at screening. Patient may, alternatively, 
agree to a core biopsy prior to treatment if reviewed and deemed feasible by an 
interventional radiologist. 
• Optional biopsy at Screen.  Also optional on or between Cycle 4 day 1 (+/- 5 days), 
OR upon progression if earlier than Cycle 4 day 1. 
• 10 ml tube of whole blood (genomic blood tube “GBT”) at screen (for possible 
genomic analysis)

After Cycle 1, pre-dose laboratory procedures can be conducted up to 72 hours prior to 
dosing.  Results must be reviewed by the investigator or qualified designee and found to be 
acceptable prior to each dose of trial treatment.  
7.1.3.2 Withdrawal/Discontinuation 
When a subject discontinues/withdraws prior to trial completion, all applicable activities 
scheduled for the final trial visit should be performed at the time of discontinuation.  Any 
adverse events which are present at the time of discontinuation/withdrawal should be 
followed in accordance with the safety requirements outlined in Section 7.2 - Assessing and 
Recording Adverse Events.  Subjects who a) attain a CR or b) complete 24 months of 
treatment with pembrolizumab (MK-3475) may discontinue treatment with the option of 
restarting treatment if they meet the criteria specified in Section 7.1.5.2.1.  After 
discontinuing treatment following assessment of CR, these subjects should return to the site 
for a Safety Follow-up Visit (described in Section 7.1.5.3.1) and then proceed to the Follow-
Up Period of the study (described in Section 7.1.5.4). 
7.1.3.3 Blinding/Unblinding 
This is an open label study without placebo.  No blinding will be performed.  
7.1.4 Visit Requirements 
Visit requirements are outlined in Section 6.0 - Trial Flow Chart.   Specific procedure-related 
details are provided above in Section 7.1 - Trial Procedures. 
7.1.4.1 Screening 
• Screening will only be done after an initial pre-eligibility determination is made using 
those requirements that are part of the medical history (disease and treatment history, 
recent labs or scans, etc.), do not require specific testing, where it appears the patient 
may be eligible for study, and after an informed consent is made. 
• Screening labs and radiology are done in accordance with the sections listed 
respectively above. 
• As part of screening, the requirements for biological samples must be confirmed.. 
7.1.4.2 Treatment Period 
• Patients will remain on treatment until  
o any of the criteria in section 5.8. 
o a patient reaches a CR after 6 cycles and investigator and patient wish to 
discontinue paclitaxel.  Pembrolizumab should continue.

o 24 months of pembrolizumab 
o follow-up will be to progression at minimum.  Survival may be followed up to 
2.5 years per the discretion of the sponsor. 
7.1.4.3 Post-Treatment Visits 
• Please see study calendar. 
7.1.4.3.1  Safety Follow-Up Visit 
The mandatory Safety Follow-Up Visit should be conducted approximately 30 days after the 
last dose of trial treatment or before the initiation of a new anti-cancer treatment, whichever 
comes first. All AEs that occur prior to the Safety Follow-Up Visit should be recorded.  
Subjects with an AE of Grade > 1 will be followed until the resolution of the AE to Grade 0-
1 or until the beginning of a new anti-neoplastic therapy, whichever occurs first. SAEs that 
occur within 90 days of the end of treatment or before initiation of a new anti-cancer 
treatment should also be followed and recorded.   
7.1.4.4 Follow-up Visits 
Subjects who discontinue trial treatment for a reason other than disease progression will 
move into the Follow-Up Phase and should be assessed every 9 weeks (± 4 days) by 
radiologic imaging to monitor disease status. Every effort should be made to collect 
information regarding disease status until the start of new anti-neoplastic therapy, disease 
progression, death, or end of the study.  Information regarding post-study anti-neoplastic 
treatment will be collected if new treatment is initiated. 
7.1.4.4.1 Survival Follow-up 
Once a subject experiences confirmed disease progression or starts a new anti-cancer 
therapy, the subject moves into the survival follow-up phase and should be contacted by 
telephone every 12 weeks (± 7 days) to assess for survival status until death, withdrawal of 
consent, or the end of the study, whichever occurs first.  
7.2 
Assessing and Recording Adverse Events 
An adverse event is defined as any untoward medical occurrence in a patient or clinical 
investigation subject administered a pharmaceutical product and which does not necessarily 
have to have a causal relationship with this treatment. An adverse event can therefore be any 
unfavorable and unintended sign (including an abnormal laboratory finding, for example), 
symptom, or disease temporally associated with the use of a medicinal product or protocol-
specified procedure, whether or not considered related to the medicinal product or protocol-
specified procedure. Any worsening (i.e., any clinically significant adverse change in 
frequency and/or intensity) of a preexisting condition that is temporally associated with the 
use of the Merck’s product, is also an adverse event.

Confidential  Limited Access 
 
Changes resulting from normal growth and development that do not vary significantly in 
frequency or severity from expected levels are not to be considered adverse events.  
Examples of this may include, but are not limited to, teething, typical crying in infants and 
children and onset of menses or menopause occurring at a physiologically appropriate time. 
Merck product includes any pharmaceutical product, biological product, device, diagnostic 
agent or protocol-specified procedure, whether investigational (including placebo or active 
comparator medication) or marketed, manufactured by, licensed by, provided by or 
distributed by Merck for human use. 
Adverse events may occur during the course of the use of Merck product in clinical trials or 
within the follow-up period specified by the protocol, or prescribed in clinical practice, from 
overdose (whether accidental or intentional), from abuse and from withdrawal. 
Adverse events may also occur in screened subjects during any pre-allocation baseline period 
as a result of a protocol-specified intervention, including washout or discontinuation of usual 
therapy, diet, placebo treatment or a procedure. 
All adverse events will be recorded from the start of treatment through 30 days following 
cessation of treatment and at each examination on the Adverse Event case report 
forms/worksheets. The reporting timeframe for adverse events meeting any serious criteria is 
described in section 7.2.3.1. 
Adverse events will not be collected for subjects during the pre-screening period (for 
determination of archival tissue status) as long as that subject has not undergone any 
protocol-specified procedure or intervention.  If the subject requires a blood draw, fresh 
tumor biopsy etc., the subject is first required to provide consent to the main study and AEs 
will be captured according to guidelines for standard AE reporting. 
7.2.1 Definition of an Overdose for This Protocol and Reporting of Overdose to the 
Sponsor and to Merck 
For purposes of this trial, an overdose will be defined as any dose exceeding the prescribed 
dose for pembrolizumab (MK-3475) by 20% over the prescribed dose. No specific 
information is available on the treatment of overdose of pembrolizumab (MK-3475). In the 
event of overdose, the subject should be observed closely for signs of toxicity. Appropriate 
supportive treatment should be provided if clinically indicated. 
If an adverse event(s) is associated with (“results from”) the overdose of a Merck product, 
the adverse event(s) is reported as a serious adverse event, even if no other seriousness 
criteria are met. 
If a dose of Merck’s product meeting the protocol definition of overdose is taken without any 
associated clinical symptoms or abnormal laboratory results, the overdose is reported as a 
non-serious Event of Clinical Interest (ECI), using the terminology “accidental or intentional 
overdose without adverse effect.”

All reports of overdose with and without an adverse event must be reported within 24 hours 
to the Sponsor and within 2 working days hours to Merck Global Safety. (Attn: Worldwide 
Product Safety; FAX 215 993-1220) 
7.2.2 Reporting of Pregnancy and Lactation to the Sponsor and to Merck 
Although pregnancy and lactation are not considered adverse events, it is the responsibility of 
investigators or their designees to report any pregnancy or lactation in a subject 
(spontaneously reported to them) that occurs during the trial or within 120 days of 
completing the trial, or 30 days following cessation of treatment if the subject initiates new 
anticancer therapy, whichever is earlier.  All subjects who become pregnant must be 
followed to the completion/termination of the pregnancy.  Pregnancy outcomes of 
spontaneous abortion, missed abortion, benign hydatidiform mole, blighted ovum, fetal 
death, intrauterine death, miscarriage and stillbirth must be reported as serious events 
(Important Medical Events). If the pregnancy continues to term, the outcome (health of 
infant) must also be reported. 
Such events must be reported within 24 hours to the Sponsor and within 2 working days to 
Merck Global Safety. (Attn: Worldwide Product Safety; FAX 215 993-1220) 
7.2.3 Immediate Reporting of Adverse Events to the Sponsor and to Merck 
7.2.3.1 Serious Adverse Events 
A serious adverse event is any adverse event occurring at any dose or during any use of 
Merck’s product that: 
• Results in death; 
• Is life threatening; 
• Results in persistent or significant disability/incapacity; 
• Results in or prolongs an existing inpatient hospitalization; 
• Is a congenital anomaly/birth defect; 
• Is a new cancer (that is not a condition of the study); 
• Is associated with an overdose; 
• Is another important medical event  
Progression of the cancer under study is not considered an adverse event (AE) unless it 
results in hospitalization or death.  If the latter are due to progression, it is not a drug-related 
AE. 
Any serious and unanticipated toxicities believed at least possibly related to combination 
treatment should prompt the Primary Investigator to suspend enrollment to the trial and 
submit an ad hoc report and plan to the PMC before continuing enrollment.   
Any serious adverse event, or follow up to a serious adverse event, including death due to 
any cause other than progression of the cancer under study that occurs to any subject from

the time the consent is signed through 90 days following cessation of treatment, or the 
initiation of new anti-cancer therapy, whichever is earlier, whether or not related to 
investigational product, must be reported within 24 hours to the Sponsor and within 2 
working days to Merck Global Safety.  
Non-serious Events of Clinical Interest will be forwarded to Merck Global Safety and will be 
handled in the same manner as SAEs.  
Additionally, any serious adverse event, considered by an investigator who is a qualified 
physician to be related to Merck product that is brought to the attention of the investigator at 
any time outside of the time period specified in the previous paragraph also must be reported 
immediately to the Sponsor and to Merck. 
SAE reports and any other relevant safety information are to be forwarded to the Merck 
Global Safety facsimile number:  +1-215-993-1220 
A copy of all 15 Day Reports and Annual Progress Reports is submitted as required by FDA, 
European Union (EU), Pharmaceutical and Medical Devices agency (PMDA) or other local 
regulators. Investigators will cross reference this submission according to local regulations to 
the Merck Investigational Compound Number (IND, CSA, etc.) at the time of submission.  
Additionally investigators will submit a copy of these reports to Merck & Co., Inc. (Attn: 
Worldwide Product Safety; FAX 215 993-1220) at the time of submission to FDA. 
All subjects with serious adverse events must be followed up for outcome. 
Information about all serious adverse events will be collected and recorded. To ensure patient 
safety, each serious adverse event must be reported to the PI and to the sponsor 
expeditiously. Moffitt Cancer Center and all participating sites will report SAEs by 
completing an SAE report in Oncore, the electronic data capture system. The SAE must be 
reported by email (affiliate.research@moffitt.org) to the MCRN within 2 working days. If 
applicable, the site should also follow protocol guidelines for additional reporting to 
government agencies. 
 
7.2.3.2 Events of Clinical Interest 
Selected non-serious and serious adverse events are also known as Events of Clinical Interest 
(ECI) (Please see and must be recorded as such on the Adverse Event case report 
forms/worksheets and reported within 24 hours to the Sponsor and within 2 working days to 
Merck Global Safety. (Attn: Worldwide Product Safety; FAX 215 993-1220) 
Events of clinical interest for this trial include: 
1.  An overdose of Merck product, as defined in Section 7.2.1 - Definition of an Overdose for 
This Protocol and Reporting of Overdose to the Sponsor, that is not associated with clinical 
symptoms or abnormal laboratory results.

2.  an elevated AST or ALT lab value that is greater than or equal to 3X the upper limit of 
normal and an elevated total bilirubin lab value that is greater than or equal to 2X the upper 
limit of normal and, at the same time, an alkaline phosphatase lab value that is less than 2X 
the upper limit of normal, as determined by way of protocol-specified laboratory testing or 
unscheduled laboratory testing.* 
*Note:  These criteria are based upon available regulatory guidance documents. The 
purpose of the criteria is to specify a threshold of abnormal hepatic tests that may require 
an additional evaluation for an underlying etiology.  The trial site guidance for 
assessment and follow up of these criteria can be found in the Investigator Trial File 
Binder (or equivalent). 
3.  In the event a subject develops any of the following AEs, a detailed narrative of the event 
should be reported as an ECI to the Sponsor within 24 hours and to Merck Global Safety 
within 2 working days of the event: 
a.  Grade ≥ 3 diarrhea 
b.  Grade ≥  3 colitis 
c.  Grade ≥ 2 pneumonitis 
d.  Grade ≥ 3 hypo- or  hyperthyroidism 
 
A separate guidance document has been provided entitled “event of Clinical Interest and 
Immune-Related Adverse Event Guidance Document.”  This document provides guidance 
regarding identification, evaluation and management of ECIs and irAEs.  Additional ECIs are 
identified in this guidance document and also need to be reported to the Sponsor within 24 
hours and to Merck Global Safety within 2 working days of the event.   
Subjects should be assessed for possible ECIs prior to each dose.  Lab results should be 
evaluated and subjects should be asked for signs and symptoms suggestive of an immune-
related event.  Subjects who develop an ECI thought to be immune-related should have 
additional testing to rule out other etiologic causes.  If lab results or symptoms indicate a 
possible immune-related ECI, then additional testing should be performed to rule out other 
etiologic causes.  If no other cause is found, then it is assumed to be immune-related.  
ECIs that occur in any subject from the date of first dose through 90 days following cessation 
of treatment, or the initiation of a new anticancer therapy, whichever is earlier, whether or 
not related to the Merck’s product, must be reported within 24 hours to the Sponsor and to 
Merck Global Safety within 2 working days. 
7.2.4 Evaluating Adverse Events 
An investigator who is a qualified physician will evaluate all adverse events according to the 
NCI Common Terminology for Adverse Events (CTCAE), version 4.0. Any adverse event 
which changes CTCAE grade over the course of a given episode will have each change of 
grade recorded on the adverse event case report forms/worksheets.

†Results in death; or 
 
†Is life threatening; or places the subject, in the view of the investigator, at immediate risk of death from the event as it occurred (Note: This does not include an 
adverse event that, had it occurred in a more severe form, might have caused death.); or 
 
†Results in a persistent or significant disability/incapacity (substantial disruption of one’s ability to conduct normal life functions); or 
 
†Results in or prolongs an existing inpatient hospitalization (hospitalization is defined as an inpatient admission, regardless of length of stay, even if the 
hospitalization is a precautionary measure for continued observation. (Note: Hospitalization [including hospitalization for an elective procedure] for a preexisting 
condition which has not worsened does not constitute a serious adverse event.); or 
 
†Is a congenital anomaly/birth defect (in offspring of subject taking the product regardless of time to diagnosis);or 
 
Is a new cancer; (that is not a condition of the study) or 
 
Is an overdose (whether accidental or intentional).  Any adverse event associated with an overdose is considered a serious adverse event. An overdose that is not 
associated with an adverse event is considered a non-serious event of clinical interest and must be reported within 24 hours. 
 
Other important medical events that may not result in death, not be life threatening, or not require hospitalization may be considered a serious adverse event when, 
based upon appropriate medical judgment, the event may jeopardize the subject and may require medical or surgical intervention to prevent one of the outcomes 
listed previously (designated above by a †). 
Duration 
Record the start and stop dates of the adverse event. If less than 1 day, indicate the appropriate length of time and units 
Action taken  
Did the adverse event cause the Merck product to be discontinued? 
Relationship to 
test drug  
Did the Merck product cause the adverse event? The determination of the likelihood that the Merck product caused the adverse event will be provided by an 
investigator who is a qualified physician. The investigator’s signed/dated initials on the source document or worksheet that supports the causality noted on the AE 
form, ensures that a medically qualified assessment of causality was done. This initialed document must be retained for the required regulatory time frame. The 
criteria below are intended as reference guidelines to assist the investigator in assessing the likelihood of a relationship between the test drug and the adverse event 
based upon the available information.  
The following components are to be used to assess the relationship between the Merck product and the AE; the greater the correlation with the components and 
their respective elements (in number and/or intensity), the more likely the Merck product caused the adverse event (AE): 
 
Exposure 
Is there evidence that the subject was actually exposed to the Merck product such as: reliable history, acceptable compliance assessment (pill 
count, diary, etc.), expected pharmacologic effect, or measurement of drug/metabolite in bodily specimen? 
 
Time Course 
Did the AE follow in a reasonable temporal sequence from administration of the Merck product?  
Is the time of onset of the AE compatible with a drug-induced effect (applies to trials with investigational medicinal product)? 
 
Likely Cause 
Is the AE not reasonably explained by another etiology such as underlying disease, other drug(s)/vaccine(s), or other host or environmental 
factors

Relationship 
The following components are to be used to assess the relationship between the test drug and the AE: (continued) 
to Merck 
product 
(continued)  
Dechallenge 
Was the Merck product discontinued or dose/exposure/frequency reduced? 
If yes, did the AE resolve or improve? 
If yes, this is a positive dechallenge. If no, this is a negative dechallenge. 
(Note: This criterion is not applicable if: (1) the AE resulted in death or permanent disability; (2) the AE resolved/improved despite continuation 
of the Merck product; or (3) the trial is a single-dose drug trial); or (4) Merck product(s) is/are only used one time.) 
 
Rechallenge 
Was the subject re-exposed to the Merck product in this study? 
If yes, did the AE recur or worsen? 
If yes, this is a positive rechallenge. If no, this is a negative rechallenge. 
(Note: This criterion is not applicable if: (1) the initial AE resulted in death or permanent disability, or (2) the trial is a single-dose drug trial); or 
(3) Merck product(s) is/are used only one time). 
NOTE: IF A RECHALLENGE IS PLANNED FOR AN ADVERSE EVENT WHICH WAS SERIOUS AND WHICH MAY HAVE BEEN 
CAUSED BY THE MERCK PRODUCT, OR IF REEXPOSURE TO THE MERCK PRODUCT POSES ADDITIONAL POTENTIAL 
SIGNIFICANT RISK TO THE SUBJECT, THEN THE RECHALLENGE MUST BE APPROVED IN ADVANCE BY THE U.S. CLINICAL 
MONITOR AS PER DOSE MODIFICATION GUIDELINES IN THE PROTOCOL. 
 
Consistency 
with Trial 
Treatment 
Profile 
Is the clinical/pathological presentation of the AE consistent with previous knowledge regarding the Merck product or drug class pharmacology 
or toxicology? 
The assessment of relationship will be reported on the case report forms /worksheets by an investigator who is a qualified physician according to his/her best clinical judgment, including 
consideration of the above elements. 
Record one of the following 
Use the following scale of criteria as guidance (not all criteria must be present to be indicative of a Merck product relationship). 
Yes, there is a reasonable 
possibility of Merck product 
relationship. 
There is evidence of exposure to the Merck product.  The temporal sequence of the AE onset relative to the administration of the Merck product 
is reasonable.  The AE is more likely explained by the Merck product than by another cause. 
No, there is not a reasonable 
possibility Merck product 
relationship 
Subject did not receive the Merck product OR temporal sequence of the AE onset relative to administration of the Merck product is not 
reasonable OR there is another obvious cause of the AE.  (Also entered for a subject with overdose without an associated AE.)

8.0 STATISTICAL ANALYSIS PLAN 
8.1 
Statistical Analysis Plan Summary 
Primary Endpoint 
Progression free survival at 6 months (6-month PFS) by RECIST 1.1.   
Progression-free Survival (PFS) is defined as the time from the date of the first dose to the 
time of disease progression or death, whichever occurs first.  6-month PFS is defined as the 
proportion of patients without disease progression or death at 6 months.  For comparison 
purposes, PFS will be assessed separately according to immune-related RECIST criteria 
(irRC), RECIST v1.1, and CA125 Rustin criteria. If a subject has not experienced disease 
progression or death at the time of a data lock, the subject will be censored at the last tumor 
assessment date (for RECIST v1.1 and irRC) or the last CA125 assessment date (for CA125 
Rustin criteria).  Progression-free Survival will be analyzed on response assessable treated 
subjects at the time of the analysis of survival endpoints. A separate analysis will be 
conducted using irRC, but the primary endpoint is based on RECIST 1.1 as in other studies 
of Pembrolizumab for solid cancers. 
 
Sample Size 
There will be 50 enrolled patients, 37 evaluable patients. 
Enrollment Period 
This trial will have 37 evaluable patients enrolled over a 1.5-year period or less, averaging 2-
3 patients per month. 
Replacement of Patients 
Patients will be considered unevaluable for the primary endpoint of 6-month PFS by RECIST 
V1.1 if they are not able to complete the first tumor assessment scan at cycle 4. Unevaluable 
patients will be replaced therefore it is estimated that 50 patients will need to be enrolled to 
result in 37 evaluable patients.  
Sample Size Justification

Under the assumption that the 6-month PFS in the historical control arm (e.g. AURELIA) is 
0.25, it is expected that treatment arm will result in a 50% reduction in the risk of progression 
at 6 months (6-mo PFS =0.5).  The enrollment period is approximately 1.5 years and the 
follow-up time is 1.5 years after the last enrolled patient. We assume a 5-10% drop-out or 
non-evaluable rate; so estimate total enrollment of 40. With 37 evaluable patients, we will 
have 90% power at a one-sided 0.05 level of significance to reject the null hypothesis.  
The null hypothesis that the true 6-month PFS rate is 0.25 will be tested against a one-sided 
alternative. The null hypothesis will be rejected if 14 or more with a 6-month PFS are 
observed in 37 evaluable patients. This design yields a type I error rate of 0.05 and a type II 
error rate of 0.1 when the true alternative 6-mo PFS rate is 0.5.  
Safety will be a descriptive analysis.  Other secondary endpoints will be described as point 
estimates with confidence intervals. 
Interim Analysis  
Given the short duration of enrollment, the 6-month PFS endpoint, and the relatively small 
number of patients, there will be no pause in enrollment for an interim analysis.

Other Analyses 
• Response rate 
o Response rate (RR) using the Best Overall Response (BOR) will be 
determined and reported.  RR= CR + PR. 
o Response rate (RR)  is defined as the proportion of all response assessable 
treated subjects whose best response at any time during the study to date 
following initiation of therapy is a CR or PR. This will be assessed according 
to irRC, as well as separately by RECIST v1.1 criteria, and by CA125 Rustin 
criteria. RR will be analyzed at the same time as the analysis of the primary 
endpoint, as well as at subsequent analysis of the survival endpoints. 
• Disease Control Rate (clinical benefit) 
o DCR = CR + PR + (SD x 2mo) 
• Duration of response 
o Duration of response is defined as the time that a response was first identified 
(CR or PR) until the time with a progression was first determined.  
• Overall Survival 
o Median OS will be determined.

1. 0 Baseline: Measurable Lesion 
Definitions and Target Lesion 
Selection 
Follow the definitions from RECIST 1.1. 
Measurable lesions must be accurately measured in at least one dimension with 
a minimum size of: 
• 10 mm in the longest diameter by CT or MRI scan (or no less than double the 
slice thickness) for nonnodal lesions and ≥15 mm in short axis for nodal lesions 
• 10 mm caliper measurement by clinical exam 
• 20 mm by chest X-ray 
 
1.1. Baseline: Non-measurable 
Lesion Definitions 
Follow the definitions from RECIST 1.1 
Non-target lesions will include: 
• Measurable lesions not selected as target lesions 
• All sites of non-measurable disease, such as neoplastic masses that are too 
small to measure because their longest uninterrupted diameter is < 10 mm (or < 
two times the axial slice thickness), ie. the longest per-pendicular diameter is 
≥10 and < 15 mm. 
• Other types of lesions that are confidently felt to represent neoplastic tissue, 
but are difficult to measure in a reproducible manner. 
These include bone metastases, leptomeningeal metastases, malignant ascites, 
pleural or pericardial effusions, ascites, inflammatory breast disease, 
lymphangitis cutis/pulmonis, cystic lesions, ill-defined abdominal masses, skin 
lesions, etc.

1.2 Baseline: Target and Non-Target 
Lymph Node Lesion Definitions 
Follow the definitions from RECIST 1.1 
1.3 Baseline: Non-Target 
Lesion Selection 
All lesions or sites of disease not recorded as target lesions should be recorded 
as non-target lesions at baseline. There is no limit to the number of non-target 
lesions that can be recorded at baseline. 
 
1.4 Baseline: Bone Lesions  
Follow the definitions from RECIST 1.1. 
Regardless of the imaging modality blastic bone lesions will not be selected as 
target lesions. Lytic or mixed lytic-blastic lesions with a measurable soft tissue 
component ≥10 mm can be selected as target lesions. 
 
1.5 Baseline: Brain Lesions detected on brain scans can be considered as both 
target or non-target lesions. 
 
1.6 Baseline: Cystic and Necrotic Lesions as Target Lesions 
Lesions that are partially cystic or necrotic can be selected as target lesions. The 
longest diameter of such a lesion will be added to the Total Measured Tumor 
Burden (TMTB) of 
all target lesions at baseline. If other lesions with a non-liquid/non-necrotic 
component are present, those should be preferred. 
 
1.7 Baseline: Lesions With Prior Local Treatment 
During target lesion selection the radiologist will consider information on the 
anatomical sites of previous intervention (e.g. previous irradiation, RF-ablation, 
TACE, surgery, etc.). Lesions undergoing prior intervention will not be selected 
as target lesions unless there has been a demonstration of progress in the lesion 
 
1.8 Baseline: No Disease at Baseline 
If a patient has no measurable and no non-measurable disease at baseline the 
radiologist will assign ‘No Disease’ (irND) as the overall tumor assessment for 
any available follow-up timepoints unless new measurable lesions are identified 
and contribute to the TMTB.

The longest diameters of non-nodal target and new non-nodal measurable 
lesions, and short axes of nodal target and new nodal measurable lesions will be 
recorded. Together they determine the Total Measured Tumor Burden (TMTB) 
at follow-up. 
 
2.1 Follow-up: Definition of Measurable New Lesions 
In order to be selected as new measurable lesions (≤ 2 lesions per organ, 
≤ 5 lesions total, per timepoint), new lesions must meet criteria as defined for 
baseline target lesion selection and meet the same minimum size requirements 
of 10 mm in long 
diameter and minimum 15 mm in short axis for new measurable lymph nodes. 
New measurable lesions shall be prioritized according to size, and the largest 
lesions shall be selected as new measured lesions. 
 
2.2 Follow-up: Non-Target Lesion Assessment 
The RECIST 1.1 definitions for the assessment of non-target lesions apply. 
The response of non-target lesions primarily contributes to the overall response 
assessments of irCR and irNon-CR/Non-PD (irNN). Non-target lesions do not 
affect irPR and irSD assessments. Only a massive and unequivocal worsening of 
non-target lesions alone, even without progress in the TMTB is indicative of 
irPD. 
 
2.3 Follow-up: New Non-Measurable Lesions Definition and Assessment  
All new lesions not selected as new measurable lesions are considered new non-
measurable lesions and are followed qualitatively. Only a massive and 
unequivocal progression of new non-measurable lesions leads to an overall 
assessment of irPD for the timepoint. Persisting new nonmeasurable lesions 
prevent irCR. 
 
2.4 irRC Overall Tumor Assessments 
irCR, complete disappearance of all measurable and non-measurable lesions. 
Lymph nodes must decrease to < 10 mm in short axis. Confirmation of response 
is not mandatory. 
irPR, decrease of ≥ 30% in TMTB relative to baseline, non-target lesions are 
irNN, and no unequivocal progression of new non-measurable lesions. irSD, 
failure to meet criteria for irCR or irPR in the absence of irPD. irNN, no target 
disease was identified at baseline and at follow-up the patient fails to meet 
criteria for irCR or irPD.  
irPD, minimum 20% increase and minimum 5 mm absolute increase in TMTB 
compared to nadir, or irPD for non-target or new non-measurable lesions.  
Confirmation of progression is recommended minimum 4 weeks after
