The purpose of this study is to assess the safety and efficacy of ruxolitinib in patients with operable Head and neck squamous cell carcinoma (HNSCC) who are planned for definitive surgery.

Detailed description:
PRIMARY OBJECTIVES:

I. To identify baseline and/or pharmacodynamic biomarkers of response to ruxolitinib, based upon association with quantitative change in tumor size following 14-21 days of neoadjuvant ruxolitinib in patients with operable HNSCC as determined by quantitative change in Tumor size.

SECONDARY OBJECTIVES:

I. To describe the tolerability of brief neoadjuvant exposure to ruxolitinib II. To assess the effect of ruxolitinib on the tumoral Ki-67 proliferation index III. To evaluate additional candidate biomarkers of ruxolitinib response or resistance in HNSCC patients as determined by quantitative change in Tumor size,

OUTLINE:

Participants will be assigned neoadjuvant ruxolitinib based on participant platelet counts at baseline. Participants with a platelet count of 200,000 or greater will take 20 mg twice daily and participants with a platelet count between 150,000 and 200,000 will take 15 mg twice daily. Participants may continue treatment for up to 4 weeks from the time of study entry to time of planned standard of care surgery for cancer. Participants will be followed up for 12-weeks post-operation.

Arms: arm 1: Participants will take 15 mg or 20 mg of ruxolitinib by mouth twice daily for up to 4 weeks during the pre-operative window for 14-21 days, or up to 28 days for delays in planned surgery. Dose will be assigned based on participant platelet count at baseline. The last dose will be taken the morning of planned surgery. Ruxolitinib will be dispensed in 5 mg tablets. Participants will either take three tables (15 mg) in the morning and evening, or four tablets in the morning and evening (20 mg). Participants will be asked to fill out a drug diary indicating when doses of study drug are taken and any side effects they experience.

Abstract
Title
Pharmacodynamic effects and predictive biomarkers of JAK/STAT inhibition with 
ruxolitinib in operable head and neck cancer: a window trial
Patient 
population
Patients with de novo or recurrent stage I-IVa head and neck squamous cell 
carcinoma (HNSCC) who are planned for definitive surgery. 
Rationale for 
Study
Head and neck squamous cell carcinoma (HNSCC) is responsible for over 11,500 
deaths in the United States alone each year, and despite advances in surgical, 
radiation, and chemotherapy treatment, overall survival rates have only increased 
incrementally over the past few decades. Aberrant STAT regulation is commonly 
seen in HNSCC, although direct pharmacologic targeting of this family of 
transcriptional factors has proven difficult. However, the Janus kinases (JAK) have 
been shown to modulate the activity of signal transducer and activator of 
transcription (STAT)-3 in HNSCC preclinical models, and small molecule JAK 
inhibitors have recently been developed. The potential utility of JAK modulation in 
HNSCC has not yet been tested.
Primary 
Objective

To identify baseline and/or pharmacodynamic biomarkers of response to 
ruxolitinib, based upon association with quantitative change in tumor size 
(ΔTumor size) following 14-21 days of neoadjuvant ruxolitinib in patients with 
operable HNSCC as determined by quantitative ΔTumor size
Secondary 
Objectives

To describe the tolerability of brief neoadjuvant exposure to ruxolitinib

To assess the effect of ruxolitinib on the tumoral Ki-67 proliferation index 

To evaluate additional candidate biomarkers of ruxolitinib response or 
resistance in HNSCC patients as determined by quantitative ΔTumor size, 
including:
o
Baseline activation and/or modulation of additional JAK/STAT3 signaling 
pathway proteins
o
Baseline SHP-2 overexpression
o
Reverse-phase protein array (RPPA) will be conducted on paired pre- and 
post-treatment tissue as a source of unbiased biomarker discovery
Study Design
This is a multicenter cohort study designed to assess the effect of the JAK 1/2 
inhibitor ruxolitinib on tumor proliferation, size, and biomarker expression.
Number of 
patients
Projected accrual is 45 patients for this study, for a total of 23 biomarker-evaluable 
patients.
Duration of 
Therapy
Patients may continue treatment for up to 4 weeks from the time of study entry to 
time of planned surgery.
Duration of 
Follow up
12-weeks post-operation, as deemed clinically necessary.
Duration of 
study
The study will reach completion 24 months from the time the study opens to 
accrual.
Study Drugs
Ruxolitinib, JAKAFI®, INCB018424 (JAK 1/2 inhibitor) 20mg (or 15mg) PO BID. 
Safety 
Assessments
The safety of this window intervention will be reported descriptively, including 
tabulation of toxicities according to NCI CTCAE v.4, surgical complications, and 
length of hospital stay.
Efficacy 
Assessments
Efficacy of neoadjuvant ruxolitinib in patients with operable HNSCC as determined 
by quantitative ΔTumor size reflective of a 35% reduction.

Introduction
1.1
Background on Indication
Head and Neck Cancer
HNSCC is the sixth leading cancer worldwide, with more than 600,000 cases anticipated in 
2012.1,2 In the United States, the 2012 disease burden included 52,600 new cases and 11,500 
deaths.2 Despite advances in surgical and radiotherapy techniques, as well as integration of 
chemotherapy into multimodality treatment paradigms, HNSCC is frequently lethal. Five-year 
overall survival (OS) is 40-60% and has increased only incrementally since 1990.3 Improved 
prognosis is largely attributable to the emerging epidemic of oral human papillomavirus (HPV) 
infection. An increasing proportion of oropharyngeal HNC is driven by oncogenic HPV, rather 
than the classic risk factors of tobacco and alcohol; HPV etiology is associated with improved 
survival after conventional treatments.4,5 Although two distinct causes of HNSCC exist, 
environmental carcinogenesis or transformation by HPV oncogenes, both etiologies are 
associated with aberrant STAT 3 signaling.6-8 The association of STAT3 hyperactivation with 
poor prognosis9 and resistance to standard therapies makes it a compelling target in HNSCC.
1.2
Background on Ruxolitinib
JAKAFI®, INCB018424
Despite the importance of STAT function in a number of pathologic processes, direct 
pharmacologic inhibition of STAT is difficult. However, inhibition of upstream regulators of STAT 
function via the JAK proteins has met with more success. A number of JAK inhibitors have 
progressed to various stages of drug development, including a handful that have gained FDA 
approval. One molecule, ruxolitinib, is an inhibitor of JAK1 and JAK2, and has been approved 
by the FDA for treatment of myelofibrosis.
Preclinical Anti-tumor Activity
Ruxolitinib represents a novel, potent, and selective inhibitor of JAK1 and JAK2. Ruxolitinib 
potently inhibits JAK1 and JAK2 [half maximal inhibitory concentration (IC50) 0.4 to 1.7 nM], yet 
it does not significantly inhibit (< 30% inhibition) a broad panel of 26 kinases when tested at 200 
nM (approximately 100 times the average IC50 value for JAK enzyme inhibition) and does not 
inhibit JAK3 at clinically relevant concentrations. Pharmacological data obtained in in vivo model 
systems support the potential utility of orally administered INCB018424 in the treatment of 
malignancies, including myeloproliferative disorders such as PMF, PPV-MF and PET-MF. 
Ruxolitinib retains activity against the JAK2V617F mutant and is effective in reducing spleen 
size in mice inoculated with cells carrying this mutation. 
Preclinical Toxicology
The toxicologic and toxicokinetic profiles of ruxolitinib were characterized in single and repeat 
oral dose studies of up to 6 months in duration in rats and dogs. Genetic toxicology, safety 
pharmacology, and embryo-fetal toxicology studies have also been conducted. 
In a 6-month study in rats, doses up to 60 mg/kg/day were evaluated. An adverse decrease in 
body weight was noted in male, but not in female rats. A dose related decrease in lymphocytes 
was noted. Minimal-to-mild lymphoid depletion in spleens and in mandibular lymph nodes was 
noted at the 60 mg/kg/day dose level; at lower doses, lymphoid tissues were within normal 
histologic limits. The no-observed-adverse-effect level (NOAEL) for oral administration of 
ruxolitinib for 26 weeks was 30 mg/kg/day for the males (unbound AUC 0.119 μM*h), related to 


Version date: 03-22-2023
Protocol CC# 16201
Phase 2 - Ruxolitinib
Page 10 of 67
adverse effects on body weight at 60 mg/kg/day, and 60 mg/kg/day for female rats (unbound 
AUC 4.64 μM*h). (Lower parent drug levels in male rats are related to male rat specific 
isozymes 2C11, 2C13 and CYP3A2 that metabolize ruxolitinib to active metabolites). 
In the 6 month dog study, doses studied included 0.5, 2.5, 5, and 10 mg/kg/day. Demodectic 
mange, lymphopenia, eosinopenia, decreases in erythron parameters, moderate to severe 
cellular depletion of lymphoid tissues, bacterial pneumonia, viral-induced papillomas, 
microscopic invasive demodectic mange, and prostate hypoplasia/atrophy were seen in dogs 
that received high doses. Deaths attributed to bacterial pneumonia occurred in 3 of 14 dogs 
given 10 mg/kg/day. Demodectic mange was observed in several animals given 5 mg/kg/day 
and, microscopically, in one animal given 2.5 mg/kg/day. These events most likely reflect a 
response to the immunosuppressive effects of ruxolitinib. All tissues were normal in the 0.5 
mg/kg/day group. The NOAEL dose was defined at 2.5 mg/kg/day (unbound AUC 0.76 μM*h) 
due to minimal findings, which were not present in recovery animals. The low dose, 0.5 
mg/kg/day, was defined as the no-observed effect-level (NOEL). Additional details regarding 
dog toxicology studies are available in the Investigator Brochure (IB). 
Ruxolitinib was not genotoxic in the bacterial mutagenicity assay, the in vitro chromosome 
aberration assay, or the in vivo micronucleus assay in rats. In embryo-fetal assessments in rat 
and rabbit, maternal toxicity and minimal embryo-fetal toxicity were noted at the highest doses 
evaluated. Ruxolitinib was not teratogenic in either rat or rabbit. The NOAEL dose for the rat 
and rabbit study was 30 mg/kg/day. Additional toxicology and safety pharmacology information 
is available in the IB. 
Clinical Pharmacokinetics (PK)
Following oral, single-dose administration of ruxolitinib capsules in the fasting state, ruxolitinib 
was absorbed rapidly, typically attaining peak plasma concentrations within 1 to 3 hours after 
administration for all doses. After attaining Cmax, the ruxolitinib plasma concentrations declined 
with a mean terminal-phase disposition (t 1/2) of approximately 3-5 hours. The mean ruxolitinib 
Cmax and AUC increased with approximately linear proportionality to dose for the entire dose 
range evaluated of 5 to 200 mg. There was no significant food effect on absorption or exposure. 
Therefore, ruxolitinib can be dosed without regard to meals. 
No accumulation was seen following administration of repeated oral doses of 15 to 50 mg 
ruxolitinib twice daily (BID), and 50 to 100 mg ruxolitinib once daily for 10 days. PK parameters 
were similar to those seen following the administration of single doses. Ruxolitinib is 
metabolized in the liver by the cytochrome (CYP) P450 metabolizing enzyme system, 
predominantly by the 3A4 isozyme. The effects of the potent CYP3A4 inhibitor ketoconazole on 
the pharmacokinetics (PK) and pharmacodynamics (PD) of ruxolitinib administered as single 
oral doses shows that with concomitant dosing of ketoconazole, the observed AUC increase is 
approximately 2-fold, and the calculated Equivalent Constant Concentration (ECC) for the 
pSTAT3 PD effect was also increased approximately 2-fold. Thus, a dose reduction of ~ 50% 
for ruxolitinib is appropriate for participants who take ketoconazole or other potent CYP3A4 
inhibitors as concomitant medication (see Section 9.8.1). A more modest effect on the PK 
parameters of ruxolitinib was demonstrated with concomitant dosing of the moderate CYP3A4 
inhibitor erythromycin. No dose adjustments were necessary when ruxolitinib was co-
administered with erythromycin, or by extension, with other moderate or weak inhibitors of 
CYP3A4, including grapefruit juice.

Phase 2 - Ruxolitinib
Page 11 of 67
An open-label study to assess the effect of CYP3A4 inducers on ruxolitinib pharmacokinetics 
and pharmacodynamics revealed that, as expected, rifampin significantly decreased the 
exposure to ruxolitinib. However, essentially no difference in cytokine-induced STAT3 
phosphorylation was observed with or without rifampin induction. This suggests that CYP3A4 
induction with rifampin results in metabolism of ruxolitinib to active metabolites that also inhibit 
JAKs. Increased levels of active metabolites were seen with rifampin dosing. These data 
indicate that the dose of ruxolitinib need not be modified when dosed with CYP3A4 inducers. 
However, during the study, use of potent CYP3A4 inducers (rifampin and St. John’s Wort) is 
prohibited. Use of moderate CYP3A4 inducers (rifabutin, carbamazepine, phenytoin) is 
discouraged, and investigators should seek alternatives where possible. No dose adjustment 
will be used when these moderate CYP3A4 inducers are co-administered with study drug or 
open label ruxolitinib. Any concomitant use of CYP3A4 inducers must be documented. 
Ruxolitinib was given as a single 25 mg dose to participants with varying degrees of renal 
function, including normal (calculated creatinine clearance (CrCl) >80 mL/min), mild (CrCl 50-80 
mL/min), moderate (CrCl 30-49 mL/min) and severe (CrCl <30 mL/min) renal impairment as well 
as participants on dialysis and the PK and PD parameters measured. There was no statistically 
significant effect of mild to severe impairment of renal function on the PK or PD parameter; 
participants requiring dialysis showed decreased ruxolitinib clearance. Participants with serum 
creatinine exceeding 1.5 times the institutional upper limit of normal (ULN) will be excluded from 
the study. 
Randomized Studies
Two randomized Phase 3 studies (Studies 1 and 2) were conducted in patients with 
myelofibrosis (either primary myelofibrosis, post-polycythemia vera myelofibrosis or post-
essential thrombocythemia-myelofibrosis). In both studies, patients had palpable splenomegaly 
at least 5 cm below the costal margin and risk category of intermediate 2 (2 prognostic factors) 
or high risk (3 or more prognostic factors) based on the International Working Group Consensus 
Criteria (IWG). 
The starting dose of ruxolitinib was based on platelet count. Patients with a platelet count 
between 100 and 200 X 109/L were started on ruxolitinib 15 mg twice daily and patients with a 
platelet count greater than 200 X 109/L were started on ruxolitinib 20 mg twice daily. Doses were 
then individualized based upon tolerability and efficacy with maximum doses of 20 mg twice 
daily for patients with platelet counts between 100 to less than or equal to 125 X 109/L, of 10 mg 
twice daily for patients with platelet counts between 75 to less than or equal to 100 X 109/L, and 
of 5 mg twice daily for patients with platelet counts between 50 to less than or equal to 75 X 
109/L. 
Study 1 
Study 1 was a double blind, randomized, placebo-controlled study in 309 patients who were 
refractory to or were not candidates for available therapy. The median age was 68 years (range 
40 to 91 years) with 61% of patients older than 65 years and 54% were male. Fifty percent 
(50%) of patients had primary myelofibrosis, 31% had post-polycythemia vera myelofibrosis and 
18% had post-essential thrombocythemia myelofibrosis. Twenty-one percent (21%) of patients

(range 478 cm3 to 8881 cm3). (The upper limit of normal is approximately 300 cm3). 
Patients were dosed with ruxolitinib or matching placebo. The primary efficacy endpoint was the 
proportion of patients achieving greater than or equal to a 35% reduction from baseline in 
spleen volume at Week 24 as measured by MRI or CT. 
Secondary endpoints included duration of a 35% or greater reduction in spleen volume and 
proportion of patients with a 50% or greater reduction in Total Symptom Score from baseline to 
Week 24 as measured by the modified Myelofibrosis Symptom Assessment Form (MFSAF) v2.0 
diary. 
Study 2 
Study 2 was an open-label, randomized study in 219 patients. Patients were randomized 2:1 to 
ruxolitinib versus best available therapy. Best available therapy was selected by the investigator 
on a patient-by-patient basis. In the best available therapy arm, the medications received by 
more than 10% of patients were hydroxyurea (47%) and glucocorticoids (16%). The median age 
was 66 years (range 35 to 85 years) with 52% of patients older than 65 years and 57% were 
male. Fifty-three percent (53%) of patients had primary myelofibrosis, 31% had post-
polycythemia vera myelofibrosis and 16% had post-essential thrombocythemia myelofibrosis. 
Twenty-one percent (21%) of patients had red blood cell transfusions within 8 weeks of 
enrollment in the study. The median hemoglobin count was 10.4 g/dL and the median platelet 
count was 236 X 109/L. Patients had a median palpable spleen length of 15 cm below the costal 
margin, with 70% having a spleen length 10 cm or greater below the costal margin. Patients had 
a median spleen volume as measured by MRI or CT of 2381 cm3 (range 451 cm3 to 7765 cm3). 
The primary efficacy endpoint was the proportion of patients achieving 35% or greater reduction 
from baseline in spleen volume at Week 48 as measured by MRI or CT. 
A secondary endpoint in Study 2 was the proportion of patients achieving a 35% or greater 
reduction of spleen volume as measured by MRI or CT from baseline to Week 24. 
Study 1 and 2 Efficacy Results 
Efficacy analyses of the primary endpoint in Studies 1 and 2 are presented in Table 1 below. A 
significantly larger proportion of patients in the ruxolitinib group achieved a 35% or greater 
reduction in spleen volume from baseline in both studies compared to placebo in Study 1 and 
best available therapy in Study 2. A similar proportion of patients in the ruxolitinib group 
achieved a 50% or greater reduction in palpable spleen length.

In Study 1, myelofibrosis symptoms were a secondary endpoint and were measured using the 
modified Myelofibrosis Symptom Assessment Form (MFSAF) v2.0 diary. The modified MFSAF 
is a daily diary capturing the core symptoms of myelofibrosis (abdominal discomfort, pain under 
left ribs, night sweats, itching, bone/muscle pain and early satiety). Symptom scores ranged 
from 0 to 10 with 0 representing symptoms “absent” and 10 representing “worst imaginable” 
symptoms. These scores were added to create the daily total score, which has a maximum of 
60. 
Table 2 presents assessments of Total Symptom Score from baseline to Week 24 in Study 1 
including the proportion of patients with at least a 50% reduction (i.e., improvement in 
symptoms). At baseline, the mean Total Symptom Score was 18.0 in the ruxolitinib group and 
16.5 in the placebo group. A higher proportion of patients in the ruxolitinib group had a 50% or 
greater reduction in Total Symptom Score than in the placebo group, with a median time to 
response of less than 4 weeks.

Safety of Ruxolitinib in Clinical Studies
The safety of ruxolitinib was assessed in 617 patients in six clinical studies with a median 
duration of follow-up of 10.9 months, including 301 patients with myelofibrosis in two Phase 3 
studies. 
In these two Phase 3 studies, patients had a median duration of exposure to ruxolitinib of 9.5 
months (range 0.5 to 17 months), with 88.7% of patients treated for more than 6 months and 
24.6% treated for more than 12 months. One hundred and eleven (111) patients started 
treatment at 15 mg twice daily and 190 patients started at 20 mg twice daily. 
In a double blind, randomized, placebo-controlled study of ruxolitinib, 155 patients were treated 
with ruxolitinib. The most frequent adverse drug reactions were thrombocytopenia and anemia. 
Thrombocytopenia, anemia and neutropenia are dose related effects. The three most frequent 
non-hematologic adverse reactions were bruising, dizziness and headache.

Discontinuation for adverse events, regardless of causality, was observed in 11.0% of patients 
treated with ruxolitinib and 10.6% of patients treated with placebo. 
Following interruption or discontinuation of ruxolitinib, symptoms of myelofibrosis generally 
return to pretreatment levels over a period of approximately 1 week. There have been isolated 
cases of patients discontinuing ruxolitinib during acute intercurrent illnesses after which the 
patient’s clinical course continued to worsen; however, it has not been established whether 
discontinuation of therapy contributed to the clinical course in these patients. When 
discontinuing therapy for reasons other than thrombocytopenia, gradual tapering of the dose of 
ruxolitinib may be considered.

ruxolitinib in the double blind, placebo-controlled study during randomized treatment.

Rationale for the Proposed Study
Cumulative preclinical data implicate STAT 3 as a critical target in HNSCC; however, as with 
other transcription factors, STAT3 has been challenging to selectively and directly target. The 
recognition that hyperactivated STAT3 may result from increased upstream JAK signaling 
caused us to investigate JAK 1/2 inhibitors, including AZD1480 and ruxolitinib, in HNSCC 
preclinical models as described above. Promising preclinical results parallel findings from 
multiple solid tumors, where AZD1480 abrogated IL-6 dependent STAT3 signaling,10 justifying 
translation of JAK 1/2 targeting into human clinical trials. Novel insights into the genomic and 
epigenetic mechanisms of HNSCC tumor STAT3 activation raise the exciting possibility of 
biomarker-selection of patients most likely to respond to JAK 1/2 inhibition.
Ruxolitinib is an ATP-competitive, oral, small molecule inhibitor of the JAK1 and JAK2 kinases; 
it is the first JAK family inhibitor approved by the U.S. Food and Drug Administration (Incyte,

myelofibrosis, 2011).11 Inhibition of wild type JAK1 and JAK2 respectively has an enzyme IC50 of 
3.3 (+/- 1.2) and 2.8 (+/- 1.2) nM, concentrations easily achieved by the approved clinical 
dose.12 To date, ruxolitinib duplicates the findings of AZD1480 in our HNSCC preclinical models 
(Figures 4-8), as would be expected from its similar JAK inhibitory and pharmacokinetic profile. 
In this study, ruxolitinib will be administered for a short period of 2-3 weeks prior to planned 
surgical resection of HNSCC. The dose will be the FDA-approved dose in myelofibrosis, as 
determined by baseline platelet count: 1) Patients with a platelet count ≥ 200,000 will take 20 
mg bid (four 5mg tablets in the morning and four 5mg tablets in the evening); 2) participants with 
a platelet count ≥ 150,000 and < 200,000 will take 15 mg bid (three 5 mg tablets in the morning 
and three 5 mg tablets in the evening). The brief treatment duration is within the expected 
window of time that elapses from initial patient evaluation by a surgeon to performance of 
surgery. In the phase 0 or window trial model, a paired specimen analysis permits ex vivo 
evaluation of target modulation and pharmacodynamic changes in downstream or parallel 
molecular pathways.13 This study design is optimal in order to assess the biochemical and 
immunomodulatory effects of ruxolitinib on HNSCC. Furthermore, predictive biomarkers can be 
developed as related to a clinical endpoint (ΔTumor size) or a biochemical, pharmacodynamic 
endpoint (Δ Ki-67).
Ki-67 is a nuclear non-histone protein first characterized in 1991, which is expressed in 
proliferating human tissue.14 Down-modulation of Ki-67 is a validated surrogate biomarker in 
neoadjuvant studies of targeted therapy in breast cancer.15,16 Changes in Ki-67 observed in a 
neoadjuvant endocrine therapy study predicted the ultimate long-term disease-free survival 
advantage in the larger, adjuvant trial, whereas clinical response did not.16,17 In HNSCC window 
trials, Ki-67 modulation has not been evaluated directly against clinical outcome.18-20 An 
alternate surrogate biomarker to Ki-67, the TUNEL apoptotic index, was evaluated as the 
primary endpoint in a randomized window trial of lapatinib vs. placebo, prior to standard 
chemoradiotherapy in HNSCC.18 Although apoptosis was increased by lapatinib, the increase 
was not significant against that seen in the placebo group. Notably, the Ki-67 proliferation index 
was significantly decreased by lapatinib vs. placebo. This is in line with results from our first 
window study in HNSCC evaluating erlotinib, erlotinib-sulindac or placebo – where Ki-67 
reduction was significantly greater in the erlotinib arms vs. placebo.21  Collectively, these data 
suggest that proliferation is a worthwhile secondary endpoint for evaluation of biomarker 
correlations. 
The Jak/STAT pathway in Head and Neck Cancer
The STAT family of transcription factors is the central mediator of cellular response to cytokines 
and growth factors. Aberrant regulation of STAT3 and STAT1 in HNSCC underlies both 
malignant behavior and immune escape. STAT3 is an oncogenic transcription factor that is 
hyperactivated (phosphorylated) in a wide variety of malignancies. Studies from UPCI and other 
laboratories have shown that STAT3 transforms human epithelial cells, thereby meeting the 
definition of an oncogene. In HNSCC, STAT3 facilitates tumor growth and survival, and 
mediates resistance to standard therapies including chemoradiation and blockade of the 
epidermal growth factor receptor (EGFR).22-26
While cumulative evidence implicates STAT3 as an important target for cancer treatment, as 
with other transcription factors, STAT3 has proven challenging to inhibit selectively in humans. 
Few drugs have been amenable to clinical development. For example, an intra-operative phase 
0 trial of a STAT-3 oligonucleotide decoy in HNSCC was completed at UPCI, which reduced

target gene expression; however, the limited half-life and requirement for local injection impede 
broader clinical development.19 Increasing insight into the mechanisms of STAT3 
hyperactivation in human cancer raises the possibility of new therapeutic avenues, and may 
identify biomarkers for patient selection.
Although STAT3 is constitutively phosphorylated, activating mutations are not described in 
HNSCC27,28 or other human epithelial cancers. Thus, hyperactivated STAT3 likely results from 
excess activation of positive regulators and/or inactivation of negative regulators. STATs are 
phosphorylated by upstream growth factor receptors including Src and Janus kinases (JAK), 
and de-phosphorylated by protein tyrosine phosphatase receptors (PTPR). The activating JAK 
mutations identified in myeloproliferative disorders are not found in HNSCC.27,28 In HNSCC, IL-6 
stimulates tyrosine phosphorylation of STAT3 through JAK 1 and 2.29 The recent clinical 
development of JAK inhibitors, including ruxolitinib, raises the therapeutic plausibility of blocking 
this autocrine loop. For example, the JAK 1/2 inhibitor, AZD1480, abrogated IL-6 induced 
STAT3 phosphorylation and 
suppressed the growth of human 
solid tumor xenografts with 
constitutive STAT3 activity.10 
Moreover, a strategy for patient 
selection is emerging. While 
activating mutations in JAK or 
STAT3 are not found in HNSCC, our 
recent comprehensive mutational 
profiling of HNSCC detected 
mutations in the PTPR family of 
genes in nearly one-third of tumors.27 
Analysis of the 347 HNSCC tumors 
sequenced to date under the 
auspices of The Cancer Genome 
Atlas (TCGA) and our group, 
confirmed this high incidence of 
PTPR mutations (104/347, 30%). 
Further analysis demonstrated that 
PTPR genes are mutated in a wide array of solid tumors sequenced to date under the auspices 
of the TCGA (see Table 1). Loss of function mutations in PTPRT and PTPRD lead to increased 
STAT3 phosphorylation, suggesting a tumor suppressor role.30,31 Whole exome sequencing 
(n=374) and reverse-phase protein array data has been analyzed from 212 HNSCC tumors32. 
PTPR mutations were common and were associated with significantly increased phospho-
STAT3 expression. Expression of PTPRT mutant proteins induced STAT3 phosphorylation and 
cell survival, consistent with an oncogenic “driver” phenotype. Computational modeling revealed 
functional consequences of PTPRT mutations on phosphor-tyrosine-substrate interactions. In 
addition to genomic aberrations, PTPRT is commonly methylated in HNSCC tumors (60%, 
166/279 tumors analyzed to date in the TCGA); expression levels of PTPRT are significantly 
lower in these methylated tumors. Thus, silencing of key PTPR family genes may underlie 
STAT3 hyperactivation in HNSCC and other solid tumors. Identification and functional 
classification of these common genetic and epigenetic PTPR aberrations may permit companion 
biomarker development to select patients most likely to benefit from JAK inhibitors.

Recognition that 
hyperactivated STAT3 
likely results from increased signaling through upstream kinases, or loss of de-phosphorylation 
by silenced PTPRs, initially prompted investigation into the preclinical JAK1/2 inhibitor, 
AZD1480, in relevant HNSCC preclinical models. AZD1480 inhibited proliferation of eight 
HNSCC cell lines at low µM concentrations (data not shown). Ruxolitinib is an ATP-competitive, 
oral, small molecule inhibitor of the JAK1 and JAK2 tyrosine kinases. Inhibition of wild type 
JAK1 and JAK2 respectively has an enzyme IC50 of 3.3 (+/- 1.2) and 2.8 (+/- 1.2) nM.12 
Ruxolitinib blocked phosphorylation of pSTAT3 at Tyrosine 705 in dose-dependent fashion in 
the Cal33 HNSCC cell line (Figure 4). Furthermore, ruxolitinib inhibited growth of a FaDu 
HNSCC cell line xenograft, which harbors a loss-of-function PTPRT mutation, as compared to 
FaDu xenografts treated with vehicle control or ruxolitinib-treated PE/CA 34 HNSCC xenografts, 
which are wild type for PTPRT (Figure 4).

Figure 5: PTPRD or PTPRT mutations are found in 30% of HNSCC tumors. PTPRD and 
PTPRT mutations induce STAT3 activation, and increase sensitivity to JAK 1/2 inhibition.
The PTPRT/D mutations found in HNSCC tumors to date are shown below in Figure 6. 
Mutations in the PTP catalytic domains (PTPRT and PTPRD) and the fibronectin type 3 domain 
(PTPRD) have been reported to inhibit cellular functions of the phosphatase activity of these 
proteins.31,33 PTPRO was recently shown to behave as a tumor suppressor and decrease 
pSTAT3 in liver cancer.34 It is noteworthy that activating mutations of upstream mediators of 
STAT3 in HNSCC including EGFR, JAK, and Src were not detected in our HNSCC cohort. 
Furthermore, there was no evidence for association of PTPR mutations with HPV status. 
Published data32 illustrate that HNSCC tumors bearing PTPR mutations demonstrate higher 
pSTAT3 expression compared to PTPR wild-type. HNSCC cells transfected with a PTPRT 
mutation (A1022E or R1040L) demonstrate increased growth relative to EGFP-vector control or 
wild-type PTPR.

Correlative Biomarker Analysis
1.4.1 Primary Analysis
Correlative biomarker analysis will be performed on paired pre-treatment specimens (tumor 
biopsies and blood) and post-treatment samples to determine the modulation of biomarkers by 
ruxolitinib. Most importantly, biomarkers within the JAK/STAT signaling pathway, including JAK 
and STAT phosphorylation, PTPR mutation and methylation, inflammatory cytokines and 
HLA/APM component expression will be assessed to determine their correlation with clinical 
response to ruxolitinib. Tissue microarrays will be generated from formalin-fixed, paraffin-
embedded (FFPE) specimens, and these will be used for immunohistochemistry to assess 
tissue histology, Ki67 labeling, and expression of JAK/STAT pathway proteins, including 
phosphorylated and non-phosphorylated forms of JAK1, JAK2, STAT1, STAT3, cyclin D1 and 
Src. PTPR mutations and methylation will be determined by Sanger sequencing/Sequenom31 
and methylation-specific PCR, respectively. Finally, HLA/APM component expression will be 
evaluated using IHC or intracellular flow cytometry for TAP1, TAP2, LMP2 and calreticulin, as 
described35. Remaining specimens after these studies have been completed will be used for 
additional analysis.
1.4.2 Additional Analysis
To determine if expression of serum proteins or DNA polymorphisms predict response to 
ruxolitinib targeting, paired serum (baseline, post-treatment) and baseline peripheral blood 
mononuclear cells (PBMCs) will be isolated. Blood will be processed for serum and isolation of 
PBMCs. Serum will be analyzed for proteomic markers using mass spectroscopy and luminex 
ELISA assays. DNA will be isolated from PBMC samples for SNP analysis. Tissue will be 
processed for DNA, fluorescence in situ hybridization (FISH), tissue microarrays, and

immunohistochemistry microarrays. Both uniplex and multiplex serum cytokine profile analysis, 
for correlation with other biomarkers and clinical responsiveness will be performed. For specific 
cytokines of interest, including IL-6, ELISA kits will be used. For multiplex analysis, the 
technology developed by Luminex Corporation (Austin, TX, http://www.luminexcorp.com) will be 
used. It enables a laboratory to simultaneously measure up to 100 analytes in a single 
microplate well, using very small sample volumes (less than 50 microliters). Previous studies 
have shown that a multi-marker panel offering the highest diagnostic power was comprised of

84.5%, specificity of 98%, and 92% of patients with active head and neck cancer correctly 
classified from a cross-validation serum set36. Further proteomic analysis will be performed 
using IHC microarrays.

Objectives of the Study
2.1
Primary Objective
To identify baseline and/or pharmacodynamic biomarkers of response to ruxolitinib based upon 
association with quantitative change in tumor size (ΔTumor size) following 14-21 days of 
neoadjuvant ruxolitinib in patients with operable HNSCC. We hypothesize that ΔTumor size will 
correlate with five prioritized, predictive biomarkers which will be designated for specialized 
alpha spending: 1) baseline expression of pSTAT3; 2) change in expression of pSTAT3; 3) 
change in expression of the STAT3 target gene cyclin D1; 4) baseline silencing of protein 
tyrosine phosphatase receptors D or T (PTPRD or PTPRT) by mutation or methylation; 5) 
baseline elevation in peripheral inflammatory markers (C-reactive protein [CRP]).

Endpoints
2.3.1 Primary Endpoint

The primary efficacy endpoint of the study is clinical ruxolitinib response of 
quantitative ΔTumor size measured as a proportional percent (range -100% to +100%) 
from baseline to day 14-21.

Phase 2 - Ruxolitinib
Page 24 of 67
2.3.2 Secondary Endpoints

The size of the tumor will be determined and net ΔTumor measurements used to 
determine the response.

The safety of this window intervention will be reported descriptively, including tabulation 
of toxicities according to NCI CTCAE v.4, surgical complications, and length of hospital 
stay.

The Ki-67 proliferative index will be measured in baseline and post-treatment tumor 
tissue as described, and will serve as a secondary endpoint (pharmacodynamic 
efficacy).21 The five prioritized biomarkers will be analyzed for correlations with ΔTumor 
size, as above. In addition, they will be analyzed for correlations with ΔKi-67. 

Non-prioritized biomarkers will also be evaluated for correlations with ΔTumor size and 
ΔKi-67. In order to assess biomarker response to ruxolitinib, we will test each 
component of the biomarker panel for within-patient differences between the pre-
treatment and post-treatment biospecimens (tumor tissue and blood) and compute the p-
values for each paired test (either a paired t test or the signed rank test). We anticipate a 
panel of 15 – 20 proteins will be tested for short-term modulation with TMAs. P values 
from paired data will be adjusted to control the expected false discovery rate by the 
method of Benjamini and Hochberg. Additional analyses of secondary endpoints will be 
conducted on an exploratory and hypothesis-generating bases using available material. 
These endpoints may include qualitative and semi-quantitative scoring of IHC in tissue 
arrays, gene microarrays and serum protein measures.

Schema of Proposed Clinical Trial
 
3.2
Number of Participants
45 patients will be accrued to achieve the target of 23 eligible patients demonstrating treatment 
compliance, and with quality paired tumor specimens.
3.3
Eligibility Criteria
Surgery will be the primary curative treatment for patients enrolled in this study. Patients should 
not require any standard induction treatment prior to surgery. Surgery will have to be the best 
treatment option as determined by the treating physician. Therefore, we will not be delaying 
chemoradiotherapy or other curative treatment. We plan to include any stage of HNSCC that will 
be managed by primary surgery, including patients with newly diagnosed disease or 
locoregional recurrence scheduled for surgical salvage. If surgery is unexpectedly cancelled, the 
patient will be removed from the study unless there is an accessible lesion for biopsy. Ideally, 
the pre-treatment biopsy and the intraoperative sample will be obtained from the same site 
(when there are multiple lesions). 
3.3.1 Inclusion Criteria
1.
Histologically or cytologically confirmed, primary or recurrent, head and neck squamous 
cell carcinoma, including variants. Patients must have at least one measureable lesion in 
accordance with RECIST 1.1 (tumor diameter ≥ 1 cm; short-axis lymph node diameter ≥ 
1.5 cm) OR by caliper measurement (tumor diameter ≥ 1 cm). Any diagnostic 
pretreatment biopsy sample is acceptable including FNA. 
2.
Primary tumors of any head and neck (oral cavity, oropharynx, hypopharynx, or larynx) 
site will be included. 
3.
Surgical resection of head and neck must be planned, either as primary treatment or 
salvage. Patients must have submitted adequate pre-treatment archival or fresh tissue.

late menstrual period) at any time during study participation. 

The Investigator must immediately notify Incyte in the event of a confirmed 
pregnancy in a patient participating in the study.

Study Closure or termination

Noncompliance
3.5
Duration of Follow Up
Patients will be followed for up to 12 weeks post-operation, as deemed clinically necessary or 
removal from study, or until death, whichever occurs first. Patients removed from study for 
unacceptable treatment related adverse event(s) will be followed until resolution or stabilization 
of all treatment related adverse events to Grade 2 or lower.
3.5.1 Procedures for discontinuation 
Participants who discontinue should, if possible, be seen and assessed by an investigator(s). 
The reason for withdrawal and the date of withdrawal must be documented. If possible, any 
diary cards and investigational products should be returned by the participant as soon as 
possible after study discontinuation. If patient had screening tissue samples obtained, has taken 
at least 14 days of drug, and has undergone response assessment, they are evaluable. 
If the reason for withdrawal from the trial is the death of the participant, the two options for 
categorizing withdrawal are either disease recurrence or an adverse event (AE; more than one 


Version date: 03-22-2023

AE may be documented as a reason for withdrawal). Only one event will be captured as the 
cause of death. 
Note: death is an outcome and not an AE. All deaths that occur within the trial period or within 
30 days after administration of the last dose of trial drug must be reported to Incyte primarily for 
the purposes of serious adverse event (SAE) reporting; however, deaths due unequivocally to 
progression are not SAEs.

Study Drugs
4.1
Description, Supply and Storage of Investigational Drugs
4.1.1 Ruxolitinib (JAKAFI®, INCB018424)
Ruxolitinib is dosed orally, every morning and every evening, and can be administered with or 
without food. If a dose is missed, the patient should not take an additional dose, but should take 
the next scheduled prescribed dose. In the case of emesis, the patient should not take an 
additional dose, but should take the next scheduled prescribed dose. For patients unable to 
ingest tablets, ruxolitinib can be administered through a nasogastric or percutaneous 
gastrostomy tube (8 French or greater) as follows: 

Suspend three or four 5 mg tablets (dose dependent according to platelet count, as 
described under “Study drug treatment” in section 5.2) in approximately 40 mL of water 
with stirring for approximately 10 minutes. 

Within 6 hours after the tablets have dispersed, the suspension can be administered 
through the feeding tube using an appropriate syringe. 
The tube should be rinsed with approximately 75 mL of water. The effect of tube feeding 
preparations on ruxolitinib exposure during administration through a nasogastric tube has not 
been evaluated. 
Participants will be asked to indicate on a drug diary (see Appendix 4) when doses of study drug 
are taken in order to monitor for compliance. Participants may also use the drug diary for 
notations on side effects and other treatment related events. The Investigational Pharmacy will 
maintain a drug accountability log to record ruxolitinib received, dispensed and/or destroyed. 
Unused drugs will be destroyed locally and will not be returned.

Classification


Version date: 03-22-2023
Protocol CC# 16201
Phase 2 - Ruxolitinib
Page 29 of 67
Ruxolitinib is a Class I molecule under the Biopharmaceutical Classification System, with high 
permeability, high solubility and rapid dissolution characteristics. In clinical studies, ruxolitinib is 
rapidly absorbed after oral administration with maximal plasma concentration (Cmax) achieved 
approximately 1 hour post-dose
Mechanism of Action
Ruxolitinib (INCB018424 phosphate, INC424, ruxolitinib phosphate) represents a novel, potent, 
and selective inhibitor of JAK1 (Janus kinase 1) (inhibition concentration 50% [IC50]=3.3 ± 1.2 
nM) and JAK2 (IC50=2.8 ± 1.2 nM) with modest to marked selectivity against TYK2 (tyrosine 
kinase 2) (IC50=19 ± 3.2 nM) and JAK3 (IC50=428 ± 243 nM), respectively. Ruxolitinib 
interferes with the signaling of a number of cytokines and growth factors that are important for 
hematopoiesis and immune function.
Metabolism
Ruxolitinib was eliminated predominantly by oxidative metabolism (leading to hydroxylated 
metabolites M7, M8, M14 and M18 and keto metabolites M14 and M18 (Figure 4-1), followed in 
some cases by limited subsequent glucuronidation in humans and animal species
Contraindications
Hypersensitivity to the active substance or any of the excipients.
Potential Drug-Drug Interactions
Ruxolitinib is primarily protein bound (97%) and is metabolized by CYP3A4 in the liver. 
Significant drug-drug interaction may occur when ruxolitinib is administered with inducers or 
inhibitors of CYP3A4. Concomitant administration of ruxolitinib with strong inhibitors of CYP3A4 
such as ketoconazole may lead to significant increases in Cmax, AUC, and half-life, thus such 
patients should not be included on study. No dose adjustment is recommended when ruxolitinib 
is administered with mild inhibitors or inducers of CYP3A4, although these patients should be 
carefully monitored. Grapefruit juice is also a potent CYP3A4 inhibitor, thus the consumption of 
grapefruit juice should be avoided during ruxolitinib treatment.
Warnings and Precautions
Based on clinical experience to date in myelofibrosis, the following adverse effects may be 
associated with ruxolitinib: thrombocytopenia, anemia, neutropenia, bruising dizziness, 
headache, urinary tract infection, weight gain, flatulence, and herpes zoster. Thrombocytopenia, 
anemia, and neutropenia are dose-related effects, which occur at a median of 8 weeks after 
initiation of ruxolitinib, and in studies of longer duration have been generally treated by 
withholding ruxolitinib. Occasionally patients with anemia may require a transfusion. Patients 
taking ruxolitinib may be at risk for infection and should be monitored for this. The incidence of 
clinically significant hematologic toxicity is expected to be very low in the current study 
population, due to the short ruxolitinib exposure, as well as the absence of a primary bone 
marrow malignancy predisposing to hematologic toxicity.
Some people who take ruxolitinib have developed certain types of non-melanoma skin cancers. 
Availability
All tablets are oval and white with “INCY” on one side and “25” on the other. Additional

Dose De-escalation Rule
A continuous monitoring rule for safety will be instituted, to guard against excess toxicity from 
pre-operative treatment with ruxolitinib at the FDA-indicated starting dose for patients with 
myelofibrosis (20 mg bid for patients with a platelet count ≥ 200,000 or 15 mg bid for patients 
with a platelet count ≥ 150,000 and < 200,000). See section 8.3.3 Safety Lead-In
Table 5.2 below describes the number of toxicity events per number of treated patients required 
to trigger the ruxolitinib de-escalation rule. Table 8 also shows the posterior probability that the 
rate exceeds 33%, and the binomial probability associated with the decision for an assumed

*π is the discontinuation rate. The minimum acceptable upper bound of a treatment-related discontinuation is 33%. 
PP(π > 33%) is the posterior probability that the discontinuation rate exceeds this 33% upper bound. This posterior 
probability of discontinuation is calculated from the prior distribution, the number of participants treated and the 
observed number of treatment-related discontinuations.
5.3
Procedures in Case of Overdose
There are no known antidotes for ruxolitinib. The treatment of AEs associated with overdose 
should be supportive for the underlying adverse symptoms.
Single doses up to 200 mg have been given with acceptable acute toxicity. Doses of study 
treatment in excess of that specified (20 mg twice daily) in the clinical study protocol are 
considered to be an overdose. Overdose, with or without associated symptoms, should be 
handled in the same way as a SAE. Signs or symptoms of an overdose that meet the criteria of 
SAE should be reported as a SAE in the appropriate manner and be documented as clinical 
sequelae to an overdose. 
5.4
Procedures in Case of Pregnancy
Pregnancy in itself is not regarded as an AE unless there is a suspicion that an investigational 
product may have interfered with the effectiveness of a contraceptive treatment. All reports of 
congenital abnormalities/birth defects are SAEs. Any SAE experienced during pregnancy must 
be reported on the SAE Report Form. Elective terminations for medical reasons, and any 
serious complications of pregnancy (including spontaneous miscarriage) should be reported as 
SAEs. Elective abortions without complications should not be handled as SAEs. 
The time period for collecting information on the occurrence of a pregnancy is from first 
administration of study treatment up to and including the follow up period. The outcome of all 
pregnancies (spontaneous miscarriage, elective termination, normal birth or congenital 
abnormality/birth defects) must be followed up and documented even if the participant was 
discontinued from the study.

5.5
Dose Modifications and Dosing Delays
The following dose modification rules will be used with respect to potential toxicity. Toxicity will 
be assessed according to the NCI Common Terminology Criteria for Adverse Events Version 
4.0 (CTCAE v4.0).
Ruxolitinib is approved for use in myelofibrosis at the dose of 20 mg po bid when the baseline 
platelet count > 200,000, 15 mg po bid when the baseline platelet count is > 100,000 but ≤ 
200,000, and 5 mg bid when the baseline platelet count is > 50,000 but ≤ 100,000. Ruxolitinib is 
approved in polycythemia vera at the dose of 10 mg po bid.
Dose reductions will not be allowed. Treatment delays up to 1 week are permitted as follows: 

If participants experience any grade 3-4 ruxolitinib-related non-hematologic toxicities in 
the neo-adjuvant window, the study drug will be discontinued and they will be removed 
from the study. (Exception: Patients with asymptomatic grade 3 electrolyte abnormalities 
manageable with repletion) Patients may also be removed from study for intolerable 
non-hematologic toxicities of any grade, which persist despite optimal medical 
management.

If participants experience grade ≥ 3 thrombocytopenia or neutropenia, ruxolitinib will be 
discontinued and they will be removed from the study.

Grade 3 anemia does not require discontinuation from protocol. Patients may be 
transfused per discretion of the treating physicians.

For mild or moderate (grade 1 or 2) side effects that are difficult to tolerate, treatment 
may be held for up to 1 week. Treatment may be resumed at the same dose, if there is 
improvement by at least one grade. Dose delays more than 1 week will not be permitted. 
If treatment is restarted, study physicians should aim for at least 3 days of ruxolitinib 
exposure prior to planned surgery.
In two Phase 3 clinical studies of ruxolitinib in myelofibrosis, the median time to onset of first 
CTCAE grade two or higher anemia was 6 weeks, and approximately 8 weeks until onset of 
grade 3 or 4 thrombocytopenia. In nearly all cases, ruxolitinib-induced anemia and 
thrombocytopenia could be reversed with dose reduction or interruption; occasionally red blood 
cell or platelet transfusions were required. Thus, given the short 2-3 weeks of treatment during 
this study, it is expected that few, if any, participants will develop hematologic abnormalities. 
Moreover, participants in the current study do not have a primary bone marrow malignancy 
which is the target of ruxolitinib and thus predisposes to hematologic toxicity. Any participants 
that experience anemia or thrombocytopenia may be transfused if deemed necessary by the 
treating physician.
Although clinically significant hematologic and non-hematologic toxicity is unexpected during the 
14-21 days of protocol treatment in patients with operable HNSCC, a continuous monitoring rule 
for excess toxicity will be instituted. Please see Section 5.6 below.
5.6
Monitoring and Toxicity Management
Each patient receiving ruxolitinib will be evaluable for safety. The safety parameters include all 
laboratory tests and hematological abnormalities, physical findings, and spontaneous reports of 
adverse events reported to the investigator by patients.
Each patient will be assessed periodically for the development of any toxicity as outlined in 
Section 6 Study Procedures and Observations. Toxicity will be assessed according to the NCI 


Version date: 03-22-2023

Phase 2 - Ruxolitinib
Page 33 of 67
CTCAE v4.0. Dose adjustments will be made according to the system showing the greatest 
degree of toxicity. 
We will monitor for the following anticipated adverse events:
Anemia 
In the two Phase 3 clinical studies, median time to onset of first CTCAE Grade 2 or higher 
anemia was approximately 6 weeks. One patient (0.3%) discontinued treatment because of 
anemia. In patients receiving ruxolitinib, mean decreases in hemoglobin reached a nadir of 
approximately 1.5 to 2.0 g/dL below baseline after 8 to 12 weeks of therapy and then gradually 
recovered to reach a new steady state that was approximately 1.0 g/dL below baseline. This 
pattern was observed in patients regardless of whether they had received transfusions during 
therapy. 
In the randomized, placebo-controlled study, 60% of patients treated with Jakafi and 38% of 
patients receiving placebo received red blood cell transfusions during randomized treatment. 
Among transfused patients, the median number of units transfused per month was 1.2 in 
patients treated with ruxolitinib and 1.7 in placebo treated patients. 
Thrombocytopenia 
In the two Phase 3 clinical studies, in patients who developed Grade 3 or 4 thrombocytopenia, 
the median time to onset was approximately 8 weeks. Thrombocytopenia was generally 
reversible with dose reduction or dose interruption. The median time to recovery of platelet 
counts above 50 X 109/L was 14 days. Platelet transfusions were administered to 4.7% of 
patients receiving ruxolitinib and to 4.0% of patients receiving control regimens. Discontinuation 
of treatment because of thrombocytopenia occurred in 0.7% of patients receiving ruxolitinib and 
0.9% of patients receiving control regimens. Patients with a platelet count of 100 X 109/L to 200 
X 109/L before starting ruxolitinib had a higher frequency of Grade 3 or 4 thrombocytopenia 
compared to patients with a platelet count greater than 200 X 109/L (16.5% versus 7.2%). 
Neutropenia 
In the two Phase 3 clinical studies, 1.0% of patients reduced or stopped ruxolitinib because of 
neutropenia.
Table 5.6 provides the frequency and severity of clinical hematology abnormalities reported for 
patients receiving treatment with Jakafi or placebo in the placebo-controlled study.

Additional Data from the Placebo-controlled Study 
25.2% of patients treated with ruxolitinib and 7.3% of patients treated with placebo developed 
newly occurring or worsening Grade 1 abnormalities in alanine transaminase (ALT). The 
incidence of greater than or equal to Grade 2 elevations was 1.9% for ruxolitinib with 1.3% 
Grade 3 and no Grade 4 ALT elevations. 
17.4% of patients treated with ruxolitinib and 6.0% of patients treated with placebo developed 
newly occurring or worsening Grade 1 abnormalities in aspartate transaminase (AST). The 
incidence of Grade 2 AST elevations was 0.6% for ruxolitinib with no Grade 3 or 4 AST 
elevations. 
16.8% of patients treated with ruxolitinib and 0.7% of patients treated with placebo developed 
newly occurring or worsening Grade 1 elevations in cholesterol. The incidence of Grade 2 
cholesterol elevations was 0.6% for ruxolitinib with no Grade 3 or 4 cholesterol elevations.

a.
History and physical examination within 8 weeks prior to study entry. This should include surgical assessment of the primary tumor, including fiberoptic 
nasopharyngoscopy or examination under anesthesia as indicated per standard of care, and as determined by the treating surgeon. Patients will be 
reevaluated within 5 days prior to scheduled surgery. Toxicity and compliance as evidenced by pill count and patient diaries will be assessed. 
b.
Pre-menopausal women of childbearing potential (WOCBP) must have a negative urine or serum pregnancy test within 4 weeks of registration. A negative 
pregnancy test must then be documented within 72 hours of Day 1 of ruxolitinib treatment. 
c.
The standard of care EKG performed for pre-surgical evaluation should be used. EKGs performed within 12 weeks prior to study entry may be substituted, 
provided the patient has experienced no interval cardiac event.

d.
Clinical blood tests include CBC with differential (to include total white blood cell count, absolute neutrophil count, hemoglobin, hematocrit and platelets), 
serum chemistries (to include sodium, potassium, chloride, HCO3, BUN, creatinine, glucose, magnesium and calcium), liver function tests (to include total 
bilirubin, AST, ALT, total protein, albumin and alkaline phosphatase), coagulation studies (PT/INR and PTT), and C-reactive protein (CRP). Clinical blood tests 
will be repeated once within 5 days prior to surgery, and at the 4-week and 12-week post-operative visits if clinically indicated according to the investigator. 
Coagulation studies are not required at the 4 week or 12 week post-surgical visits. 
e.
Within 6 weeks of study entry (within 4 weeks preferred), and again within 5 days prior to planned surgery, patients will undergo cross-sectional radiological 
evaluation using diagnostic contrasted CT, PET/CT (with diagnostic contrasted CT), or MRI of regions with radiologically or clinically identifiable tumor. The 
minimum cross-sectional evaluation is a diagnostic, contrasted computed tomography (CT) scan of the neck. PET/CT is the preferred modality, provided it 
includes a diagnostic, contrasted CT scan of the neck – however is not mandatory. For patients with severe allergy to iodinated contrast dye despite 
premedication, or in the case of physician preference, neck MRI may be substituted. The pre- and post-treatment imaging modality should be the same, i.e. if 
MRI was used at study entry, it should be used at the post-treatment, pre-surgical assessment. NOTE: in the event that a patient lacks a CT-measurable 
primary tumor or metastatic lymph node, measurable disease may also be established by caliper measurement of an oral cavity or oropharyngeal tumor (≥ 1 
centimeter). In this case, caliper measurement should be repeated within 5 days prior to planned surgery.
f.
The first day of ruxolitinib treatment will be considered Day 1. Ruxolitinib will be administered at 20 mg po bid, for 1421 days, and will be discontinued on the 
day of surgical resection (following the morning dose). If surgery is delayed, the study drug may be continued until surgery, for a maximum of 28 days. The 
interval between the last dose of ruxolitinib and surgery will be 2-24 hours.
g.
Surgery will be scheduled during days 14-21 of ruxolitinib treatment. For logistical reasons, surgery may be delayed by up to 7 days. Postoperative 
complications, hospital days, and ICU days will be noted for each patient. 
h.
Research blood samples will be obtained at screening and within the 5 days prior to scheduled surgery. One (1) purple top EDTA tube will be collected at 
each time point. Please refer to the laboratory SOPs for processing instructions.
i.
Archival tissue if available. If no archival tissue is available participants must undergo tissue biopsy at baseline. Research biopsies obtained at screening 
during planned surgery for resection of the tumor will be divided into fresh, fresh-frozen and paraffin specimens.
j.
Patients will be seen for a standard 4 week post-operative visit (+/- 2 weeks), and again for a standard 12-week post-operative visit (+/- 4 weeks). Clinical 
blood tests will be obtained as deemed clinically necessary. Thereafter, patients will be followed off study per standard of care.

Participant Registration
A written, signed, informed consent form (ICF) and a Health Insurance Portability and 
Accountability Act (HIPAA) authorization must be obtained before any study-specific 
assessments are initiated. A copy of the signed ICF will be given to the participant and a copy 
will be filed in the medical record. The original will be kept on file with the study records. 
All patients who are consented will be registered in OnCore®, the UCSF Helen Diller Family 
Comprehensive Cancer Center Clinical Trial Management System (CTMS). The system is 
password protected and meets HIPAA requirements.
Each participating site is responsible for OnCore® registration of study participants consented at 
the site.
6.3
Schedule of Procedures and Observations
6.3.1 Screening Period
Pretreatment or Screening Evaluations (Baseline, within 4 weeks prior to study registration 
unless otherwise specified)
Required screening evaluations include: 

Tumor tissue sample:
o
Patients who have had research tissue procured under an omnibus tissue 
consent, who are determined to have sufficient fresh, fresh-frozen, and paraffin 
tissue for biomarker analysis, may substitute the archived tissue and do not need 
to undergo screening research biopsy provided no interval anti-neoplastic 
therapy was given.
o
Baseline research biopsy: If no archival tissue is available participants must 
undergo tissue biopsy at baseline (see below):

Examination under anesthesia (EUA) with triple endoscopy is strongly 
recommended, if not previously performed and/or if an appropriate 
standard of care for surgical staging. EUA may include direct 
laryngoscopy, bronchoscopy and esophagoscopy in order to fully 
evaluate the extent of primary tumor and rule out evidence of a second 
primary aerodigestive tract tumor. A thorough description of the 
anatomical extent of the head and neck primary tumor will be detailed by 
the surgeon in the EUA operative report. Biopsy of the primary tumor for 
diagnosis, if not already done, will be performed during the EUA 
according to standard pathologic procedures. Research biopsy of the 
primary tumor for biomarker studies during the EUA is required if no 
archival tissue is available. Alternately, patients for whom an in-office 
biopsy with local anesthesia is feasible may have the baseline research 
biopsy performed in the outpatient office of the otolaryngologist or head 
and neck surgeon.
o
Tissue for biomarker analysis will be processed according to procedures 
described in Appendix 5. 


Version date: 03-22-2023
Protocol CC# 16201
Phase 2 - Ruxolitinib
Page 38 of 67

Blood collection. The patient is required to undergo blood collection for biomarker 
assessment. For logistical purposes, research labs may be drawn simultaneous with 
blood labs required for standard clinical management.
o
Blood for biomarker analysis will be processed according to procedures 
described in Appendix 5.

History and physical examination, to include surgical and medical evaluation, within 8 
weeks prior to study registration, including a careful description of the location and 
extent of the primary lesion and nodal spread. Fiberoptic 
nasopharyngoscopy/laryngoscopy is recommended, unless fiberoptic exam is deemed 
unnecessary by the treating surgeon. 

Vital signs, weight, height within 8 weeks prior to study registration

ECOG Performance Status within 8 weeks prior to study registration 

Laboratory studies including CBC with differential (to include total white blood cell count, 
absolute neutrophil count, hemoglobin, hematocrit and platelets), serum chemistries (to 
include sodium, potassium, chloride, carbon dioxide, BUN, creatinine, glucose, 
magnesium and calcium), liver function tests (LFTs; to include total bilirubin, AST, ALT, 
total protein, albumin and alkaline phosphatase), coagulation studies (PT/INR and PTT), 
and C-reactive protein (CRP). 

Negative serum pregnancy test within 4 weeks of study registration in WOCBP. Note, 
the clinical research coordinator or treating investigator will document an additional 
negative pregnancy test within 72 hours of starting ruxolitinib treatment.

Cross-sectional radiologic evaluation within 6 weeks of study registration (within 4 weeks 
is preferred). The minimum cross-sectional evaluation is a diagnostic, contrasted 
computed tomography (CT) scan of the neck. PET/CT is the preferred modality, 
provided it includes a diagnostic, contrasted CT scan of the neck – however is not 
mandatory. For patients with severe allergy to iodinated contrast dye despite 
premedication, or in the case of physician preference, neck MRI may be substituted. If 
MRI is used for baseline imaging, it should also be used for response assessment (post-
treatment, pre-surgical imaging). This is standard of care for baseline assessment. The 
post treatment assessment is research.

EKG. The standard of care EKG performed for pre-surgical evaluation should be used. 
EKGs performed within 12 weeks prior to study registration may be substituted, provided 
the patient has experienced no interval cardiac event.
6.3.2 Treatment Period
Days 1-28; NOTE ruxolitinib treatment is planned for 14-21 days, however may be administered 
up to 28 days if required for logistical/scheduling purposes.
6.3.2.1 Day 1
Ruxolitinib will be administered at the FDA-approved dose in myelofibrosis, as determined by 
baseline platelet count: 1) Patients with a platelet count ≥ 200,000 will take 20 mg bid (four 5mg 
tablets in the morning and four 5mg tablets in the evening); 2) participants with a platelet count 
≥ 150,000 and < 200,000 will take 15 mg bid (three 5 mg tablets in the morning and three 5 mg 
tablets in the evening). Ruxolitinib will be discontinued on the day of surgical resection (following 
the morning dose). If surgery is delayed, the study drug may be continued until surgery, for a 


Version date: 03-22-2023
Protocol CC# 16201
Phase 2 - Ruxolitinib
Page 39 of 67
maximum of 28 days. Fourteen days is the minimum required treatment for a patient to be 
considered evaluable. The interval between the last dose of ruxolitinib and surgery will be 2-24 
hours. 
Ruxolitinib will be dispensed as 5mg tablets. Participants with a platelet count ≥ 200,000 will 
take 20 mg bid (four 5mg tablets in the morning and four 5mg tablets in the evening). 
Participants with a platelet count ≥ 150,000 and < 200,000 will take 15 mg bid (three 5 mg 
tablets in the morning and three 5 mg tablets in the evening). 
Participants will be asked to indicate on a drug diary (see Appendix 4) when doses of study drug 
are taken in order to monitor for compliance. Participants may also use the drug diary for 
notations on side effects and other treatment related events.
6.3.2.2 Day 9-28 (inclusive of day of surgery)
Post-treatment, pre-surgical 
NOTE: all efforts should be made to schedule these evaluations on the day prior to or the day of 
surgery, however a 5 day window is provided for logistical purposes.

History and Physical Examination (Post-treatment, Pre-operative): Participants will be 
evaluated by history and physical examination by the treating physician within 5 days 
prior to planned surgery (including vital signs, weight, performance status). This visit will 
also include toxicity and compliance assessment. Compliance as evidenced by pill count 
and patient drug diary will be assessed. For logistical convenience, this visit may be 
scheduled in conjunction with blood collection and imaging as specified below. NOTE: 
Participants will continue to take ruxolitinib until the morning of planned surgery. If 
surgery is delayed, participants will continue to take ruxolitinib and this pre-operative 
history and physical examination does not need to be repeated.

Blood Collection (Clinical and Research Blood): Participants will undergo repeat CBC 
with differential, serum chemistries, LFTs, coagulation studies and C-reactive protein 
within 5 days prior to planned surgery. Research blood will be drawn simultaneously with 
these standard pre-operative labs. NOTE: Participants will continue to take ruxolitinib 
until the morning of planned surgery. If surgery is delayed, participants will continue to 
take ruxolitinib and these pre-operative blood tests do not need to be repeated.

Cross-sectional Imaging for Tumor Measurements (Research): Participants will undergo 
a repeat diagnostic CT scan of the neck with IV contrast within 5 days prior to planned 
surgery. If a neck MRI was performed in lieu of CT scan at baseline, then a MRI should 
be substituted at response assessment. NOTE: Participants will continue to take 
ruxolitinib until the morning of planned surgery. If surgery is delayed, participants will 
continue to take ruxolitinib and this pre-operative imaging does not need to be repeated.
NOTE: in the event that a patient lacks a CT-measurable primary tumor or metastatic 
lymph node, measurable disease may be established by caliper measurement of an oral 
cavity or oropharyngeal tumor (≥ 1 centimeter). In this case, caliper measurement should 
be repeated and documented within 5 days prior to planned surgery, as a substitute for 
cross-sectional imaging.

6.3.2.3 Surgery (Occurring Between Days 14-28, Inclusive)
The nature of complete resection of the primary head and neck tumor, type of reconstruction, 
and levels of nodes to be dissected will be determined by the treating surgeon. Prior to surgery, 
dental evaluation is recommended, to allow for any necessary dental extractions to be planned 
in conjunction with surgery. Consultations with a Nutritionist and Speech and Language 
Pathologist are strongly recommended prior to surgery and as ongoing support. Placement of a 
nasogastric (e.g. Dobhoff) or gastrostomy feeding tube is at the discretion of the participant and 
the study physicians. Following 14-21 days (+ 7 days if required for logistical and scheduling 
purposes) of treatment prior to participant’s scheduled surgery, a surgeon will resect the 
participant’s tumor (days 14-28). Part of the tumor specimen will be sent to the research 
laboratory for mandatory biomarker analyses. If surgery is unexpectedly cancelled, the patient 
will be removed from the study unless the primary tumor is accessible for in-office biopsy in the 
judgment of the surgeon-investigator, in which case a tumor biopsy may be substituted for the 
operative specimen. Tissue collection procedures are described in Section 9.0. 
6.3.2.4 Post-operative therapy
After surgery, participants may receive adjuvant radiation or radiation plus chemotherapy in 
accordance with appropriate standards, as determined by the participant’s treating physicians.
6.3.3 End-of-Treatment/Final Study Visit Procedures
A standard history and physical examination and blood tests as clinically indicated (CBC, 
chemistries, liver function tests in accordance with investigator judgment) will be performed 4 
weeks (+/- 2 week) and 12 weeks (+/- 4 weeks) post-surgery. Additional non-protocol visits may 
occur during the 12-week post-operative period as deemed clinically necessary. Patients will be 
referred for adjuvant chemotherapy and radiation per standard of care, based upon pathologic 
findings. Once the first 12 weeks of follow-up have been completed, study follow-up will be 
discontinued and participants will continue standard treatment and surveillance in accordance 
with national guidelines. 
The standard post-operative visit which occurs 12 weeks post-op (+/- 4 weeks) will be 
considered the “final study visit.” 
Post-Therapy Radiologic Evaluation
Within 6 weeks prior to registration (within 4 weeks preferred), and again within the 5 days prior 
to planned surgery, patients will undergo cross-sectional radiological evaluation using diagnostic 
contrasted CT, PET/CT (with diagnostic contrasted CT), or MRI of regions with radiologically or 
clinically identifiable tumor. The minimum cross-sectional evaluation is a diagnostic, contrasted 
computed tomography (CT) scan of the neck. PET/CT is the preferred modality, provided it 
includes a diagnostic, contrasted CT scan of the neck – however is not mandatory. For 
patients with severe allergy to iodinated contrast dye despite premedication, or in the case of 
physician preference, neck MRI may be substituted. The pre- and post-treatment imaging 
modality should be the same, i.e. if MRI was used at study entry, it should be used at the post-
treatment, pre-surgical assessment. Modified Response Evaluation Criteria in Solid Tumors 
version 1.1 (RECIST v1.1)37 criteria will be used to establish target lesions. 
NOTE: in the event that a patient lacks a CT-measurable primary tumor or metastatic lymph 
node, measurable disease may also be established by caliper measurement of an oral cavity or 


Version date: 03-22-2023

oropharyngeal tumor (≥ 1 centimeter). In this case, caliper measurement should be repeated 
within 5 days prior to planned surgery.
6.4
Usage of Concurrent/Concomitant Medications
6.4.1 Dietary Restrictions
Patients will be instructed to avoid grapefruit or grapefruit juice, starfruit, or Seville oranges.
6.4.2 Prohibited Medications
Strong CYP3A4 inhibitors. For eligibility, patients must discontinue drug 7 days prior to starting 
ruxolitinib, including but not limited to boceprevir, clarithromycin, conivaptam, indinavir, 
itraconazle, ketoconazole, lopinavir, mibefradil, nefazodone, nelfinavir, posaconazole, ritonavir, 
saquinavir, telaprevir, telithromycin, or voriconazole.

Reporting and Documentation of Results
7.1
Evaluation of Efficacy: Antitumor Effect – Solid Tumors
Response and progression in this study will be evaluated using the new international criteria 
proposed by the Response Evaluation Criteria in Solid Tumors (RECIST) Committee [JNCI 
92(3):205-216, 2000]. Changes in only the largest diameter (unidimensional measurement) of 
the tumor lesions are used in the RECIST v1.1 criteria (or International Workshop on Chronic 
Lymphocytic Leukemia [IWCLL]).
7.1.1 Definitions
Evaluable for toxicity
All patients will be evaluable for toxicity from the time of their first treatment with the study drug.
Evaluable for objective response
Only those patients who have measurable disease present at baseline, have received at least 
one cycle of therapy, and have had their disease re-evaluated will be considered evaluable for 
response. These patients will have their response classified according to the definitions stated 
below. (Note: Patients who exhibit objective disease progression prior to the end of Cycle 1 will 
also be considered evaluable.)
7.1.2 Disease Parameters
Measurable disease
Measurable disease is defined as lesions (or tumors) that can be accurately measured in at 
least one dimension (longest diameter to be recorded) with a minimum size of 10mm by CT 
scan (irrespective of scanner type) and MRI (no less than double the slice thickness and a 
minimum of 10mm), 10mm caliper measurement by clinical exam (when superficial), and/or 
20mm by chest X-ray (if clearly defined and surrounded by aerated lung).
All tumor measurements will be recorded in millimeters or decimal fractions of centimeters. 
Previously irradiated lesions are considered non-measurable except in cases of documented 
progression of the lesion since the completion of radiation therapy.


Version date: 03-22-2023
Protocol CC# 16201
Phase 2 - Ruxolitinib
Page 42 of 67
Target lesions
All measurable lesions up to a maximum of 5 lesions total (and a maximum of two lesions per 
organ) representative of all involved organs should be identified as target lesions and recorded 
and measured at baseline. Target lesions will be selected on the basis of their size (lesions with 
the longest diameter) and their suitability for accurate repeated measurements (either by 
imaging techniques or clinically). A sum of the longest diameter (LD) for all target lesions will be 
calculated and reported as the baseline sum LD. The baseline sum LD will be used as reference 
by which to characterize the objective tumor response.
Non-target lesions
All other lesions (or sites of disease) including any measurable lesions over and above the 5 
target lesions should be identified as non-target lesions and should also be recorded at 
baseline. It is possible to record multiple non-target lesions involving the same organ as a single 
item on the case record form (e.g. “multiple enlarged pelvic lymph nodes” or “multiple liver 
metastases”). Bone lesions may be measureable if ≥ 1 cm on MRI.  Measurements of these 
lesions are not required, but the presence or absence of each will be noted throughout follow-
up.
Non-measurable disease (Tumor Markers)
Non-measurable disease is all other lesions (or sites of disease), including small lesions 
(longest diameter < 20 mm with conventional techniques or < 10 mm using spiral CT scan). 
Leptomeningeal disease, ascites, pleural or pericardial effusion, inflammatory breast disease, 
lymphangitic involvement of skin or lung, abdominal masses/abdominal organomegaly identified 
by physical exam that is not measurable by reproducible imaging techniques are all non-
measurable. (e.g., PSA, CA-125, CA19-9, CEA)
7.1.3 Methods for Evaluation of Measurable Disease
All measurements will be taken and recorded in metric notation using a ruler or calipers. All 
baseline evaluations will be performed as closely as possible to the beginning of treatment and 
never more than 28 days before the beginning of the treatment.
The same method of assessment and the same technique will be used to characterize each 
identified and reported lesion at baseline and during follow-up. Imaging-based evaluation is 
preferred to evaluation by clinical examination when both methods have been used to assess 
the antitumor effect of a treatment.
7.1.4 Response Criteria
Complete Response (CR)
Disappearance of all target lesions, determined by two separate observations conducted not 
less than 4 weeks apart. Any pathological lymph nodes (whether target or non-target) must 
have reduction in short axis to <10 mm (the sum may not be “0” if there are target nodes). There 
can be no appearance of new lesions.


Version date: 03-22-2023
Protocol CC# 16201
Phase 2 - Ruxolitinib
Page 43 of 67
Partial Response (PR)
At least a 30% decrease in the sum of the longest diameter (LD) of target lesions, taking as 
reference the baseline sum LD. There can be no appearance of new lesions.
Progressive Disease (PD)
At least a 20% increase in the sum of the SLD of target lesions, taking as reference the smallest 
sum SLD recorded since the treatment started and minimum 5 mm increase over the nadir, or 
the appearance of one or more new lesions.
Stable Disease (SD)
Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as 
reference the smallest sum LD since the treatment started.
Evaluation of Non-Target Lesions
Complete Response (CR)
Disappearance of all non-target lesions and normalization of tumor marker level. All lymph 
nodes must be non-pathological in size (< 10 mm short axis).
Incomplete Response/Stable Disease (SD)
Persistence of one or more non-target lesion(s) and/or maintenance of tumor marker level 
above the normal limits.
Progressive Disease (PD)
Appearance of one or more new lesions and/or unequivocal progression of existing non-target 
lesions.
Evaluation of Best Overall Response
The best overall response is the best response recorded from the start of the treatment until 
disease progression.
Evaluation of Target Lesions
Complete Response (CR)
Disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) 
must have reduction in short axis to <10 mm.
Partial Response (PR)
At least a 30% decrease in the sum of target lesion diameters (longest diameter of non-nodal 
lesions; short axis diameter of the target lymph nodes), /recurrence (taking as reference the 
baseline sum diameter.
Progressive Disease (PD)
At least a 20% increase in the sum of target lesion diameters (longest diameter of non-nodal 
lesions; short axis diameter of the target lymph nodes), taking as reference for progressive 
disease the smallest sum diameter measurements recorded since the baseline sum diameter 
measurements. In addition to the relative increase of 20%, the sum must also demonstrate an 
absolute increase of at least 5 mm. Note: the appearance of one or more new lesions is also 
considered progressions. The patient's best response assignment will depend on the 
achievement of both measurement and confirmation criteria.

Evaluation of Safety
Analyses will be performed for all patients having received at least one dose of study drug. The 
study will use the CTCAE v4.0 for reporting of non-hematologic adverse events and modified 
criteria for hematologic adverse events, see Appendix 2.
The Principal Investigator at the UCSF Coordinating Center will hold the role of Study Chair. 
The Study Chair is responsible for the overall conduct of the study and for monitoring its safety 
and progress at all participating sites.
7.3
Definitions of Adverse Events
7.3.1 Adverse Event
An adverse event (also known as an adverse experience) is defined as any untoward medical 
occurrence associated with the use of a drug in humans, whether or not considered drug 
related. More specifically, an adverse event (can be any unfavorable and unintended sign (e.g., 
an abnormal laboratory finding), symptom, or disease temporally associated with the use of a 
drug, without any judgment about causality. An adverse event can arise from any use of the 
drug (e.g., off-label use, use in combination with another drug) and from any route of 
administration, formulation, or dose, including an overdose. 
7.3.2 Adverse Reaction
An adverse reaction is defined as any adverse event caused by the use of a drug. Adverse 
reactions are a subset of all suspected adverse reactions for which there is reason to conclude 
that the drug caused the event.
7.3.2.1 Suspected 
A suspected adverse reaction is defined as any adverse event for which there is a reasonable 
possibility that the drug caused the adverse event. For the purposes of IND safety reporting, 


Version date: 03-22-2023
Protocol CC# 16201
Phase 2 - Ruxolitinib
Page 45 of 67
“reasonable possibility” indicates that there is evidence to suggest a causal relationship 
between the drug and the adverse event. A suspected adverse reaction implies a lesser degree 
of certainty about causality than an adverse reaction.
7.3.2.2 Unexpected 
An adverse event or suspected adverse reaction is considered unexpected if it is not listed in 
the investigator brochure or package insert(s), or is not listed at the specificity or severity that 
has been observed, or, if an investigator brochure is not required or available, is not consistent 
with the risk information described in the general investigational plan or elsewhere in the current 
application. 
“Unexpected,” as used in this definition, also refers to adverse events or suspected adverse 
reactions that are mentioned in the investigator brochure as occurring with a class of drugs or 
as anticipated from the pharmacological properties of the drug, but are not specifically 
mentioned as occurring with the particular drug under investigation.
Adverse events that would be anticipated to occur as part of the disease process are 
considered unexpected for the purposes of reporting because they would not be listed in the 
investigator brochure. For example, a certain number of non-acute deaths in a cancer trial 
would be anticipated as an outcome of the underlying disease, but such deaths would generally 
not be listed as a suspected adverse reaction in the investigator brochure.
Some adverse events are listed in the Investigator Brochure as occurring with the same class of 
drugs, or as anticipated from the pharmacological properties of the drug, even though they have 
not been observed with the drug under investigation. Such events would be considered 
unexpected until they have been observed with the drug under investigation. For example, 
although angioedema is anticipated to occur in some patients exposed to drugs in the ACE 
inhibitor class and angioedema would be described in the investigator brochure as a class 
effect, the first case of angioedema observed with the drug under investigation should be 
considered unexpected for reporting purposes.
7.3.2.3 Serious
An adverse event or suspected adverse reaction is considered serious if, in the view of either 
the investigator or sponsor, it results in any of the following outcomes: 

Death

Life-threatening adverse event

Inpatient hospitalization or prolongation of existing hospitalization

A persistent or significant incapacity or substantial disruption of the ability to conduct 
normal life function

Congenital anomaly/birth defect
Important medical events that may not result in death, are life threatening, or require 
hospitalization may be considered serious when, based upon appropriate medical judgment, 
they may jeopardize the patient or participant and may require medical or surgical intervention 
to prevent one of the outcomes listed in this definition. Examples of such medical events include 
allergic bronchospasm requiring intensive treatment in an emergency room or at home, blood 
dyscrasias or convulsions that do not result in inpatient hospitalization, or the development of 
drug dependency or drug abuse.

7.3.2.4 Life-threatening
An adverse event or suspected adverse reaction is considered life threatening if, in the view of 
either the investigator or sponsor, its occurrence places the patient or participant at immediate 
risk of death. It does not include an adverse event or suspected adverse reaction that, had it 
occurred in a more severe form, might have caused death. 
7.4
Recording of an Adverse Event
All grade 3 and above adverse events will be entered into OnCore®, whether or not the event is 
believed to be associated with use of the study drug. Data about these events and their severity 
will be recorded using the NCI CTCAE v4.0. 
The Investigator will assign attribution of the possible association of the event with use of the 
investigational drug, and this information will be entered into OnCore® using the classification 
system listed below: 
Relationship 
Attribution 
Description 
Unrelated
The AE is clearly NOT related to the 
intervention 
Unrelated to investigational 
drug/intervention
Unlikely
The AE is doubtfully related to the 
intervention 
Possible
The AE may be related to the intervention 
Probable
The AE is likely related to the intervention 
Related to investigational 
drug/intervention

Follow-up of Adverse Events
All adverse events will be followed with appropriate medical management until resolved. 
Patients removed from study for unacceptable adverse events will be followed until resolution or 
stabilization of the adverse event. For selected adverse events for which administration of the 
investigational drug was stopped, a re-challenge of the participant with the investigational drug 
may be conducted if considered both safe and ethical by the Investigator.
Follow-up Reports:
Additional information may be added to a previously submitted report by adding to the original 
MedWatch 3500 report and submitting it as follow-up or creating supplemental summary 
information and submitting it as follow-up with the original MedWatch 3500 form.
7.6
Adverse Events Monitoring 
All adverse events, whether or not unexpected, and whether or not considered to be associated 
with the use of the study drug, will be entered into OnCore®, as noted above.
The Investigator will assess all adverse events and determine reportability requirements to the 
UCSF Data and Safety Monitoring Committee (DSMC) and UCSF’s Institutional Review Board, 
the Institutional Review Board (IRB); and, when the study is conducted under an Investigational 
New Drug Application (IND), to the Food and Drug Administration (FDA) if it meets the FDA 
reporting criteria.
All adverse events entered into OnCore® will be reviewed by the Helen Diller Family 
Comprehensive Cancer Center Site Committee on a weekly basis. The Site Committee will 
review and discuss at each weekly meeting the selected toxicity, the toxicity grade, and the 
attribution of relationship of the adverse event to the administration of the study drug(s).
All grade(s) 3-5 adverse events entered into OnCore® will be reviewed on a monthly basis at 
the Site Committee meetings. The Site Committee will review and discuss the selected toxicity, 
the toxicity grade, and the attribution of relationship of the adverse event to the administration of 
the study drug(s).
In addition, all suspected adverse reactions considered “serious” entered into OnCore®, will be 
reviewed and monitored by the Data and Safety Monitoring Committee on an ongoing basis and 
discussed at DSMC meetings, which take place every six weeks.

Expedited Reporting 
Reporting to the Data and Safety Monitoring Committee
If a death occurs during the treatment phase of the study or within 30 days after the last 
administration of the study drug(s) and it is determined to be related either to the study drug(s) 
or to a study procedure, the Investigator or his/her designee must notify the DSMC Chair (or 
qualified alternate) within 1 business day of knowledge of the event. The contact may be by 
phone or e-mail.
Reporting to UCSF Institutional Review Board (Institutional Review Board)
The Principal Investigator must report events meeting the UCSF IRB definition of “Unanticipated 
Problem” (UP) within 5 business days of his/her awareness of the event. 
Expedited Reporting to the Food and Drug Administration
If the study is being conducted under an IND, the Sponsor-Investigator is responsible for 
determining whether or not the suspected adverse reaction meets the criteria for expedited 
reporting in accordance with Federal Regulations (21 CFR §312.32). 
The Investigator must report in an IND safety report any suspected adverse reaction that is both 
serious and unexpected. The Sponsor-Investigator needs to ensure that the event meets all 
three definitions: 

Suspected adverse reaction 

Unexpected 

Serious 
If the adverse event does not meet all three of the definitions, it should not be submitted as an 
expedited IND safety report.
The timeline for submitting an IND safety report to FDA is no later than 15 calendar days after 
the Investigator determines that the suspected adverse reaction qualifies for reporting (21 CFR 
312.32(c)(1)). 
Any unexpected fatal or life-threatening suspected adverse reaction will be reported to FDA no 
later than 7 calendar days after the Investigator’s initial receipt of the information (21 CFR 
312.32(c)(2)). 
Any relevant additional information that pertains to a previously submitted IND safety report will 
be submitted to FDA as a Follow-up IND Safety Report without delay, as soon as the 
information is available (21 CFR 312.32(d)(2)).

Statistical Considerations and Evaluation of Results
8.1
Study Endpoints
This is a phase II open label study to identify baseline and/or pharmacodynamics biomarkers of 
clinical response to ruxolitinib based on quantitative change in tumor size following 14-21 days 
of neoadjuvant ruxolitinib in patients with operable HNSCC. Clinical response will be defined by 
the change of the ΔTumor size between two measurements during study windows. 
8.2
Determination of Sample Size and Accrual Rate
8.2.1 Sample Size and Power Estimate
The primary objective of the study is to identify baseline and/or pharmacodynamic biomarkers 
that might have predictive utility to determine the clinical response to ruxolitinib. As a biomarker 
study, the statistical design is to accrue a sufficient number of patients and provide 80% power 
to test one or any of 5 key hypotheses with a shared alpha of 0.15: 1) relationship between 
clinical response (ΔTumor size) and baseline STAT activation (pSTAT3 expression); 2) 
relationship between clinical response (ΔTumor size) and change in expression of pSTAT3; 3) 
relationship between responders (ΔTumor size) and change in expression of cyclin D1; 4) 
relationship between clinical response (ΔTumor size) and baseline genetic or epigenetic PTPRT 
or PTPRD silencing; 5) relationship between responders (ΔTumor size) and baseline C-reactive 
protein. An overall alpha of .15 will be shared equally among the five primary hypotheses. 23 
patients with complete biomarker data are needed to achieve 80% power for the 5 primary 
hypothesis and limit overall family wise error rate (FWER) to 15%. As estimated from our prior 
window trials, accounting for treatment compliance and quality paired tumor specimens, this will 
require enrollment of 45 patients. For each biomarker (baseline pSTAT3 expression, change 
from baseline of pSTAT3 expression, change from baseline of cycline D1 expression, baseline 
PTPRT or PTPRD silencing and baseline C-reactive protein), mean and standard deviation will 
be estimated and compared for significance between clinical responders and non-responders of 
ruxolitinib therapy using Wilcoxon rank tests. Our experience with our phase 0 clinical trial 
testing the STAT3 decoy also showed correlations between ΔKi-67 (the primary 
pharmacodynamic efficacy endpoint) and STAT3-target genes falling in the range of .50 to .67. 
Twenty-five patients will enable a two -tailed Spearman Correlation test at alpha = .03 to detect 
a true correlation of .56. For the expected 30% of patients with a PTPR mutation, a one-tailed 
Wilcoxon test will demonstrate increased sensitivity to ruxolitinib via a decrease in tumor size 
equal to 1.3 standard deviations with 23 patients (8 with a mutation). 
8.2.2 Replacement Policy
Because this is an open label study with limited number of patients, 23 accrued eligible patients 
with clinical tumor assessments and biomarkers measurements at baseline and the end of study 
window are required for the study. Additional patients will be enrolled to replace patients without 
clinical tumor assessments and completed biomarker measurements for both time points at 
least one of the five biomarkers of interest. However, all patients will be followed and included 
for safety assessments. 
8.2.3 Safety Lead-in
A continuous monitoring rule for safety will be instituted, to guard against excess toxicity from 
pre-operative treatment with ruxolitinib at the FDA-indicated starting dose for patients with 
myelofibrosis (20 mg bid for patients with a platelet count ≥ 200,000 or 15 mg bid for patients 
with a platelet count ≥ 150,000 and < 200,000). The first cohort of 6 patients will be treated at 
this starting dose. After enrollment of the 6th patient, we will continuously monitor the number of 


Version date: 03-22-2023
Protocol CC# 16201
Phase 2 - Ruxolitinib
Page 50 of 67
patients who discontinue ruxolitinib and come off study for ruxolitinib-attributable toxicity. A 
qualifying toxicity must be at least possibly related to ruxolitinib, as judged by the treating 
investigator, and fulfill one of the following definitions:

Grade ≥ 3 non-hematologic toxicity, with the exception of asymptomatic electrolyte 
abnormalities manageable with repletion. 

Intolerable non-hematologic toxicities of any grade, which persist despite optimal 
medical management.

Grade ≥ 3 thrombocytopenia or neutropenia.
If the posterior probability of ≥ 33% toxicity rate exceeds 50% for patients having to discontinue 
window treatment due to qualifying toxicity, this would be considered unacceptable and would 
result in de-escalating the starting dose of ruxolitinib to 10 mg p.o. bid, the FDA-indicated 
starting dose in polycythemia vera, for all subsequent patients. This would be the starting dose 
in all patients with a qualifying platelet count for this study (≥150,000), including those with 
platelet count ≥ 150,000 and < 200,000 and those with platelet count > 200,000. (see section 
5.2 Dose De-Escalation Rule)
8.2.4 Accrual Estimates
Accrual of 2 evaluable patients per month is expected for total enrollment period of 
approximately 12 months.
8.3
Interim Analyses and Stopping Rules
This is an open label biomarkers study. No interim analysis is planned.
8.4
Analyses Plans
8.4.1 Analysis Populations
Safety Population
The safety population will include all enrolled patients who receive at least one dose of 
ruxolitinib and have the potential to complete pharmacodynamics biomarkers assessments at 
baseline and the end of study treatment window. Although the risk from specimen collections for 
biomarker assessment is limited and low, all patients will be evaluable for toxicity and safety 
assessment of ruxolitinib. Patients who are determined ineligible after enrollment or who are not 
evaluable for safety analysis (e.g. due to withdrawal of consent or failure of specimens 
collection as not related to tumor progression and not treatment-related toxicity) will be replaced 
(see section 8.2.2 for details).
Efficacy Population
The efficacy population for the primary endpoint of 35% or greater reduction in tumor size will 
include all enrolled patients who have measurable disease present at baseline and have 
completed tumor assessment at the end of study window. Patients who are determined 
ineligible after enrollment or who are not evaluable for safety analysis (e.g. due to withdrawal of 
consent or failure of specimens collection as not related to tumor progression and not treatment-
related toxicity) will be replaced (see section 8.2.2 for details).

8.4.2 Primary Analysis (or Analysis of Primary Endpoints)
The primary objective of the study is to identify if one or any of the pharmacodynamics 
biomarkers of interest have predictive utility on the clinical tumor response to neoadjuvant 
ruxolitinib treatment in patients with operable HNSCC. The clinical response will be based on 
the reduction in Δtumor size from baseline to 14-21 days of ruxolitinib treatment: 
(1) Primary analysis using Spearman correlation between baseline pSTAT3 expression and 
%Change in tumor size will also be performed. As a supportive exploratory analysis, for 
clinical responders of patients who have achieved a 35% or greater on reduction in 
Δtumor size from baseline, descriptive statistics with mean, standard deviation and 95% 
CI will be calculated for baseline STAT activation (pSTAT3 expression) and Wilcoxon 
rank tests will be used to determine the significant difference on baseline pSTAT3 
expression between responders and non-responders.
(2) Primary analysis using Spearman correlation between change of pSTAT3 expression 
and %Change in tumor size will also be performed. As a supportive exploratory analysis, 
for clinical responders of patients who have achieved a 35% or greater on reduction in 
Δtumor size from baseline, descriptive statistics with mean, standard deviation and 95% 
CI will be calculated for change in STAT activation (pSTAT3 expression) from baseline 
and Wilcoxon rank tests will be used to determine the significant difference on change of 
pSTAT3 expression between responders and non-responders.
(3) Primary analysis using Spearman correlation between change of cyclin D1 expression 
and %Change in tumor size will also be performed. As a supportive exploratory analysis, 
for clinical responders of patients who have achieved a 35% or greater on reduction in 
Δtumor size from baseline, descriptive statistics with mean, standard deviation and 95% 
CI will be calculated for change in cyclin D1 expression from baseline and Wilcoxon rank 
tests will be used to determine the significant difference on change of cyclin D1 
expression between responders and non-responders.
(4) Primary analysis using Spearman correlation between baseline genetic or epigenetic 
PTPRT/PTPRD silencing and %Change in tumor size will also be performed. As a 
supportive exploratory analysis, for clinical responders of patients who have achieved a 
35% or greater on reduction in Δtumor size from baseline, descriptive statistics with 
mean, standard deviation and 95% CI will be calculated for baseline genetic or 
epigenetic PTPRT/PTPRD silencing and Wilcoxon rank tests will be used to determine 
the significant difference on baseline genetic or epigenetic PTPRT/PTPRD silencing 
between responders and non-responders.
(5) Primary analysis using Spearman correlation between baseline C-reactive protein level 
and %Change in tumor size will also be performed. As a supportive exploratory analysis, 
for clinical responders of patients who have achieved a 35% or greater on reduction in 
Δtumor size from baseline, descriptive statistics with mean, standard deviation and 95% 
CI will be calculated for baseline C-reactive protein level and Wilcoxon rank tests will be 
used to determine the significant difference on baseline C-reactive protein level between 
responders and non-responders.
8.4.3 Secondary Analysis (or Analysis of Secondary Endpoints)
For secondary endpoints, due to the limited sample size in the study, descriptive statistics with 
mean and 95% confidence intervals will be used. For continuous variables, descriptive statistics 
will include the number of non-missing values, mean, standard deviation, median, min and 


Version date: 03-22-2023
Protocol CC# 16201
Phase 2 - Ruxolitinib

maximum. For categorical variables, descriptive statistics will include counts and percentages per 
category. For comparison between subgroups, ANOVA and t-tests or non-parametric tests will be 
used when appropriate to determine the association of the efficacy endpoints and specific 
biomarkers. For example, descriptive statistics with mean, standard deviation and 95% CI will be 
calculated for the tumoral Ki-67 proliferation index and Wilcoxon rank tests will be used to 
determine the significant difference on the tumoral Ki-67 proliferation index between responders 
and non-responders. We will also performed additional analysis using Spearman correlation 
between the tumoral Ki-67 proliferation index and %Change in tumor size.
8.4.4 Other Analyses/Assessments
For continuous variables, descriptive statistics will include the number of non-missing values, 
mean, standard deviation, median, min and maximum. For categorical variables, descriptive 
statistics will include counts and percentages per category. 
Descriptive statistics with mean, standard deviation and 95% CI will be calculated for baseline 
JAK/STAT3 Signaling activation and Wilcoxon rank tests will be used to determine the 
significant difference on baseline JAK/STAT3 Signaling activation between responders and non-
responders.
Descriptive statistics with mean, standard deviation and 95% CI will be calculated for baseline 
and change in STAT1/STAT3 activation and Wilcoxon rank tests will be used to determine the 
significant difference on baseline and change in STAT1/STAT3 activation between responders 
and non-responders.
Descriptive statistics with mean, standard deviation and 95% CI will be calculated for baseline 
SHP-2 overexpression and Wilcoxon rank tests will be used to determine the significant 
difference on baseline SHP-2 overexpression between responders and non-responders.
8.5
Evaluation of Safety
Analyses will be performed for all patients having received at least 14 days’ worth of study drug. 
The study will use the NCI CTCAE v4.0.

monitoring and data analysis. All study data will be entered into OnCore® via standardized 
CRFs in accordance with the CTMS study calendar, using single data entry with a secure 
access account. The Clinical Research Coordinator (CRC) will complete the CRFs as soon as 
possible upon completion of the study visit; the Investigator will review and approve the 
completed CRFs. 
The information collected on CRFs shall be identical to that appearing in original source 
documents. Source documents will be found in the patient’s medical records maintained by 
UCSF personnel. All source documentation should be kept in separate research folders for each 
patient.
In accordance with federal regulations, the Investigator is responsible for the accuracy and 
authenticity of all clinical and laboratory data entered onto CRFs. The PI will approve all 
completed CRFs to attest that the information contained on the CRFs is true and accurate. 
All source documentation and CTMS data will be available for review/monitoring by the UCSF 
DSMC and regulatory agencies.
The Principal Investigator will be responsible for ensuring the accurate capture of study data. At 
study completion, when the CRFs have been declared to be complete and accurate, the 
database will be locked. Any changes to the data entered into the CRFs after that time can only 
be made by joint written agreement among the Study Chair, the Trial Statistician, and the 
Protocol Project Manager.
9.7
Oversight and Monitoring Plan
The UCSF Helen Diller Family Comprehensive Cancer Center DSMC will be the monitoring 
entity for this study. The UCSF DSMC will monitor the study in accordance with the NCI-
approved Data and Safety Monitoring Plan (DSMP). The DSMC will routinely review all adverse 
events and suspected adverse reactions considered “serious”. The DSMC will audit study-
related activities to ensure that the study is conducted in accordance with the protocol, local 
standard operating procedures, FDA regulations, and Good Clinical Practice (GCP). Significant 
results of the DSMC audit will be communicated to the IRB and the appropriate regulatory 
authorities at the time of continuing review, or in an expedited fashion, as applicable. See 
Appendix 2 Multicenter Institutional Studies Data and Safety Monitoring Plan for a Multicenter 
Study (Phase 2 or 3 Study), for additional information.

is being investigated; or, if no application is to be filed or if the application is not approved for 
such indication, until 2 years after the investigation is discontinued and FDA is notified.
9.9
Coordinating Center Documentation of Distribution
It is the responsibility of the Study Chair to maintain adequate files documenting the distribution 
of study documents as well as their receipt (when possible). The HDFCCC recommends that 
the Study Chair maintain a correspondence file and log for each segment of distribution (e.g., 
FDA, drug manufacturer, participating sites, etc.).
Correspondence file: should contain copies (paper or electronic) of all protocol versions, cover 
letters, amendment outlines (summary of changes), etc., along with distribution documentation 
and (when available) documentation of receipt.
Correspondence log: should be a brief list of all documents distributed including the date sent, 
recipient(s), and (if available) a tracking number and date received.
At a minimum, the Study Chair must keep documentation of when and to whom the protocol, its 
updates and safety information are distributed.
10
Protection of Human Subjects
10.1
Protection from Unnecessary Harm 
Each clinical site is responsible for protecting all participants involved in human 
experimentation. This is accomplished through the CHR mechanism and the process of 
informed consent. The CHR reviews all proposed studies involving human experimentation and 
ensures that the participant’s rights and welfare are protected and that the potential benefits 
and/or the importance of the knowledge to be gained outweigh the risks to the individual. The 
CHR also reviews the informed consent document associated with each study in order to 
ensure that the consent document accurately and clearly communicates the nature of the 
research to be done and its associated risks and benefits. 
10.2
Protection of Privacy
Patients will be informed of the extent to which their confidential health information generated 
from this study may be used for research purposes. Following this discussion, they will be asked 
to sign the HIPAA form and informed consent documents. The original signed document will 
become part of the patient’s medical records, and each patient will receive a copy of the signed 
document. The use and disclosure of protected health information will be limited to the 
individuals described in the informed consent document.

Appendix 2 Multicenter Institutional Studies Data and Safety Monitoring Plan for 
a Multicenter Study (Phase II or III study)
1.
Oversight and Monitoring Plan
The UCSF Helen Diller Family Comprehensive Cancer Center (HDFCCC) Data and Safety 
Monitoring Committee (DSMC) is responsible for monitoring data quality and patient safety for 
all HDF CCC institutional clinical studies. A summary of DSMC activities for this study includes: 

Review of patient data.

Review of serious adverse events.

Monitoring every six months (depending on patient accrual).

Minimum of a yearly regulatory audit.
2.
Monitoring and Reporting Guidelines
All institutional Phase II or III therapeutic studies are designated with a moderate risk 
assessment. The data is monitored by a DSMC Monitor twice per year with twenty percent of 
the patients monitored (or at least three patients if the calculated value is less than three).
The UCSF Coordinating Center provides administration, data management, and organizational 
support for the participating sites in the conduct of a multicenter clinical trial.  The UCSF 
Coordinating Center will also coordinate monthly conference calls with the participating sites to 
communicate the review of adverse events, safety data, and other study matters.
The Principal Investigator at the UCSF Coordinating Center will hold the role of Study Chair.  
The Study Chair is responsible for the overall conduct of the study and for monitoring its safety 
and progress at all participating sites.  The Study Chair will conduct continuous review of data 
and patient safety and discuss each patient’s treatment at monthly UCSF Site Committee 
meetings.  The discussions are documented in the UCSF Site Committee meeting minutes.  
Multicenter communication
The UCSF Coordinating Center provides administration, data management, and organizational 
support for the participating sites in the conduct of a multicenter clinical trial.  The UCSF 
Coordinating Center will also coordinate monthly conference calls with the participating sites.  
The following issues will be discussed as appropriate:

Enrollment information. 

Adverse Events (i.e., new adverse events and updates on unresolved adverse events 
and new safety information).

Protocol Violations.

Other issues affecting the conduct of the study.
Adverse events reporting to the DSMC will include reports from both the UCSF Coordinating 
Center, as well as the participating sites.  The DSMC will be responsible for monitoring all data 
entered in OnCore® and eFlorence (a FDA 21 CFR part 11-compliant electronic data 
repository)  at the UCSF Coordinating Center and the participating sites as per the study-
specific guidelines.  The data (i.e., copies of source documents) from the participating sites will 


Version date: 03-22-2023
Protocol CC# 16201
Phase 2 - Ruxolitinib
Page 61 of 67
be downloaded into the PC console of OnCore or from eFlorence prior to the monitoring visits in 
order for the DSMC to monitor the participating site’s compliance with the protocol and FDA 
regulations.
3.
Review and Oversight Requirements
3.1
Adverse Event Monitoring 
All Grade 3-5 Adverse Events (AEs), regardless of being unexpected or considered to 
be associated with the use of the study drug will be entered into OnCore®, UCSF’s 
Clinical Trial Management System.  
Adverse Events are graded according to the Common Terminology Criteria for Adverse 
Events (CTCAE) as developed and revised by the Common Therapy Evaluation 
Program (CTEP) of the National Cancer Institute.  Adverse Events are further given an 
assignment of attribution or relationship to treatment or medical procedure.  Attribution 
categories are:

Definite – The adverse event is clearly related to the investigational agent(s) or 
medical procedure.

Probable – The adverse event is likely related to the investigational agent(s) or 
medical procedure.

Possible – The adverse event may be related to the investigational agent(s) or 
medical procedure.

Unlikely – The adverse event is doubtfully related to the investigational agent(s) or 
medical procedure.

Unrelated – the adverse event is clearly not related to the investigational agent(s) or 
medical procedure.
All Grade 3-5 adverse events entered into OnCore® will be reviewed on a monthly basis 
at the UCSF Site Committee meetings.  All adverse events entered into OnCore® will be 
reviewed on a monthly basis at the UCSF Coordinating Center Site Committee 
meetings.  All clinically significant adverse events must be reported to the UCSF 
Coordinating Center by the participating sites within 10 business days of becoming 
aware of the event or during the next scheduled monthly conference call, whichever is 
sooner.  The UCSF Site Committee will review and discuss the selected toxicity, the 
toxicity grade, and the attribution of relationship of the adverse event to the 
administration of the study drug(s) from the UCSF Coordinating Center and the 
participating sites. 
3.2
Serious Adverse Event Reporting 
By definition, an Adverse Event is defined as a Serious Adverse Event (SAE) according 
to the following criteria:

Death.

Life-threatening (i.e. results in an immediate risk of death).

Requires inpatient hospitalization or prolongation of existing hospitalization.


Version date: 03-22-2023
Protocol CC# 16201
Phase 2 - Ruxolitinib
Page 62 of 67

Permanent or significant disability/incapacity.

Gives rise to a congenital anomaly/birth defect, or cancer, or any experience that 
suggests a significant hazard, contraindication, side effect, or precaution that may 
require medical or surgical intervention to prevent one of the outcomes listed above.

Event occurring in a gene therapy study.

Event that changes the risk/benefit ratio of a study.

Any other event the Principal Investigator judges to be serious or which would 
suggest a significant hazard, contraindication, side effect, or precaution.
Serious Adverse Event reporting will be in accordance with the UCSF IRB Regulations 
and Code of Federal Regulation Title 21 Part 312.32.  The SAE will be reported on a 
Med Watch form.  
UCSF IRB website for guidance in reporting serious adverse events:
https://irb.ucsf.edu/adverse-event
FDA website for guidance in reporting serious adverse events:
www.fda.gov/Safety/MedWatch/HowToReport/default.htm
Med Watch forms and information:
www.fda.gov/medwatch/getforms.htm
All Serious Adverse Events are entered into OnCore®, as well as submitted to the IRB 
(per IRB guidelines) via iRIS®.  All SAEs, whether expected or unexpected, must be 
reported to the UCSF Coordinating Center within 1 business days of becoming aware of 
the event.  The SAEs are reviewed and monitored by the UCSF Data and Safety 
Monitoring Committee on an ongoing basis and discussed at DSMC meetings, which 
take place every six weeks.  The date the SAE was sent to all required reporting 
agencies will be documented in OnCore®. 
If a death occurs during the treatment phase of the study or within 30 days after the last 
administration of the study drug(s) and is determined to be possibly, probably, or 
definitely related either to the investigational drug or any research related procedure, the 
Study Chair at the UCSF Coordinating Center or the assigned designee must be notified 
within 1 business day from the participating site(s) and the Study Chair must then notify 
the DSMC Chair or qualified alternate within 1 business day of this notification.  The 
reporting procedure is by communication via phone or in person with written 
documentation of the one-on-one communication via e-mail, with a copy of the e-mail to 
the DSMC Director.
3.3
Review of Adverse Event Rates
If an increase in the frequency of Grade 3 or 4 adverse events (above the rate reported 
in the Investigator Brochure or package insert) is noted in the study, the Study Chair at 
the UCSF Coordinating Center is responsible for notifying the DSMC at the time the 
increased rate is identified.  The report will indicate if the incidence of adverse events 
observed in the study is above the range stated in the Investigator Brochure or package 
insert.

Appendix 5 Specimen Collection and Processing
Specimen Collection
Blood
Peripheral blood obtained by venipuncture will serve as a source of cells for laboratory testing. 
Blood will be collected at screening and within 5 days prior to planned surgery (up to and 
including the day of surgery). One (1) purple top EDTA tube will be collected at each time point. 
Please refer to the laboratory SOPs for processing instructions. 
Tissue
Biopsy material from pre-treatment and post-treatment tumor specimens will be taken from 
either archival tissue or the initial research biopsy and at the time of surgical resection of the 
primary tumor, respectively. On both occasions, tissue estimated to be equivalent to at least two 
4 mm punch biopsies or two 18 to 14 gauge core needle biopsies will be collected. Tumor 
samples are ideally to be processed within 5-15 minutes of surgical excision. The tumor 
samples will be separated into two parts and processed as follows: 1) A tissue sample will be 
placed in a formalin filled plastic container, then embedded into paraffin for further analysis 
(FFPE). The FFPE sample will be stored in the UCSF Head and Neck Tissue Repository with 
study identifiers. 2) A fresh tissue specimen will also be banked within this mechanism. 
Tissue Processing
FFPE: For head and neck tumors, construction of tissue microarrays (TMAs) and 
immunohistochemical staining of the patient specimens will be performed at the Pathology 
Facility of UCSF. These studies will be supervised by our head and neck pathologist, Dr. 
Annemieke VanZante who directs the Tissue Core of our HNC Specialized Program of 
Research Excellence (SPORE). Dr. VanZante is experienced in TMA construction and analysis 
of protein expression. Paraffin embedded tissue blocks will be sectioned at 5μm and stained 
with H&E for morphologic characterization and to serve as guide slides for TMA construction. 
For high throughput immunohistochemical analysis and standardization of staining conditions, 
tissue microarrays (TMAs) will be constructed from formalin fixed paraffin embedded tissue 
blocks from the tumor biopsies. Using a manual tissue arrayer, (MTA-1, Beecher Instruments, 
Sun Prairie, WI) 0.6 mm tissue cores will be extracted from each pre and post treatment tumor 
in triplicate and arrayed on 1-2 recipient paraffin blocks along with normal tonsillar controls. The 
newly constructed array block will then be warmed to 35-37°C for 10 minutes to allow annealing 
of donor cores to the paraffin wax of the recipient block and minimize core loss. Donor cores will 
range from 2-4 mm in length. Hence each TMA will yield an estimated 100 to 200 tissue 
sections (4μm thickness). For TMA quality assessment morphologic confirmation of tumor, 
throughout the entire thickness of the block, one hematoxylin and eosin stained slide will be 
prepared from every ten tissue sections. Immunohistochemical evaluation of the remaining 
deparaffinized sections will be performed using immunoperoxidase staining for proteins in the 
JAK/STAT pathway including the following antigens: JAK1, JAK2, STAT1, STAT3, cyclin D1 
and Src on paraffin sections cut from the TMAs using commercially available antibodies and 
standard methods. Sections will be deparaffinized with successive ethanol and xylene baths. 
These sections will then be subjected to an optimized antigen retrieval method individualized to 
each antibody. Signal amplification will be performed using a proprietary micropolymer 
peroxidase (ImmPRESSTM, Vector, Burlingame, CA) conjugated to an anti-mouse antibody. 
Immunoreactive cells will be visualized with the brown color resulting from incubation with 
diaminobenzidine (DAB) chromogenic substrate at room temperature for 5 minutes. Sections

Phase 2 - Ruxolitinib
Page 67 of 67
will be counterstained blue with hematoxylin for 15 seconds and lithium carbonate for 5 seconds 
to provide morphologic detail. Immunohistochemical staining will be scored quantitatively for 
each core, based upon proportion of immunoreactive cells and staining intensity, with the 
assistance of computerized digital imaging (Aperio). When appropriate, separate scores for 
each case will be assigned for cytoplasmic and nuclear staining.

CONSENT TO PARTICIPATE IN A RESEARCH STUDY
CC# 16201: Pharmacodynamic Effects and Predictive Biomarkers of JAK/STAT 
Inhibition with Ruxolitinib in Operable Head and Neck Cancer: a window trial
This is a clinical trial, a type of research study. Your study doctor, William Ryan, M.D. from the 
UCSF Department of Otolaryngology Head and Neck Surgery will explain the clinical trial to 
you.
Clinical trials include only people who choose to take part. Please take your time to make your 
decision about participating. You may discuss your decision with your family and friends and 
with your health care team. If you have any questions, you may ask your study doctor.
You are being asked to take part in this study because you have stage I-IVa Head and Neck 
Squamous Cell Carcinoma (HNSCC) and plan to have surgery. If you consent to join this study 
and are eligible, you will receive the investigational drug ruxolitinib during the period of time 
between your diagnostic biopsy (if you do not have leftover tissue from a previous biopsy or 
surgery) and surgery.
Why is this study being done?
The purpose of this study is to find out if ruxolitinib shrinks tumors in patients with HNSCC, by 
analyzing biomarkers in blood and tumor samples. Biomarkers are markers in blood and tissue 
that can be used to evaluate your disease and find out how your cancer cells are responding to the 
study drug.
Ruxolitinib works to block the activation of a protein related to tumor growth and therapy 
resistance in patients with HNSCC. Ruxolitinib is approved by the United States Food and Drug 
Administration (FDA) for the treatment of myelofibrosis but not for head and neck cancer. 
Therefore, ruxolitinib is being used in this study as an investigational drug.
Incyte, the manufacturer of ruxolitinib, is supplying ruxolitinib for use in this study and 
providing money to the UCSF Helen Diller Family Comprehensive Cancer Center to perform 
this study. 
How many people will take part in this study?
A total of 23 people will participate in this study. We plan to enroll 18 patients at UCSF. Five 
patients were enrolled at the University of Arizona.

What will happen if I take part in this research study?
Before you begin the main part of the study...
You will need to have the following tests and procedures to find out if you can be in the main 
part of the study. Some of these tests or procedures are part of regular cancer care and may be 
done even if you do not join the study. If you have had some of them recently, they may not need 
to be repeated. This will be up to your study doctor.
Within 12 weeks of receiving study drug:

EKG (electrocardiogram) – An EKG records the electrical activity of your heart. 12 wires 
or “leads” will be attached to your chest with an adhesive and you will be asked to lie still 
while the machine prints out an electrical “record” of your heart activity. This takes about 
15-30 minutes (within 12 weeks of receiving study drug).
Within 8 weeks of receiving study drug:

History and physical examination (within 8 weeks of receiving study drug):
o
Medical history review – You will be asked about your health, any current and 
past illnesses.
o
Physical examination, to include medical evaluation and surgical evaluation of 
your tumor.

Vital signs - Your heart rate, breathing rate, blood pressure, and body temperature, 
height, and weight will be recorded.

Performance Status You will be asked about your general health, how you have been 
feeling, and about your daily activities.
Within 4 weeks of receiving study drug:

Blood drawing (approximately 5 tablespoons) - A blood sample will be taken by inserting 
a needle into a vein in your arm for: 
o
Routine safety tests
o
Liver function tests
o
Clotting tests

Pregnancy testing– If you are a woman of childbearing potential you will have a urine or 
blood pregnancy test. An additional negative pregnancy test must also be obtained within

CT scan: A CT (computed tomography) scan uses special x-ray equipment to 
make detailed pictures of body tissues and organs. For the CT scan, you may be 
given a "contrast material" (a special dye that makes it easier for doctors to see 
different tissues in your body). The contrast material may be given orally, 
intravenously, or rectally (less likely). Oral contrast material is given to you to 
drink and is used to help outline the stomach and intestines. Intravenous (IV) 
contrast material is given to you by injecting the contrast material into a line, 
which is attached to a needle in your arm, and is used to get clearer pictures of

your body. A rectal contrast fills up the loops of your lower bowel so the doctors 
can see your tumor better. After you have been given the contrast material, you 
will lie flat on a table that will move you into the CT scan machine. You will be 
asked to lie still and may be asked to hold your breath for a few seconds. The CT 
scan is done in the radiology department and takes about half an hour.
o
PET-CT scan: A PET (Positron Emission Tomography)-CT scan is a special type 
of test to show how the organs and cells work in your body and is done to show 
activity of the cells in your tumor. You will be asked to not eat for six hours prior 
to the scan and to drink at least two large glasses of water within one hour of the 
study. Your PET scan will begin with an injection of a radioactive substance into 
a vein in your arm. You will be asked to rest quietly for a period of time (usually 
about 20 to 40 minutes) as the radioactive substance circulates throughout your 
body. After this time, you will be positioned within a large ring (similar to a big 
donut hole) on a scanning bed. Once positioned properly, the bed will move you 
into the scanner. As pictures are being taken, you will be asked to remain very 
still so clear images will be taken. The imaging time takes about one hour.
o
MRI: An MRI (Magnetic Resonance Imaging) exam takes an image of your head 
and neck to observe the location and size of your tumor. For the MRI scan, you 
may be given a "contrast material" (a special dye that makes it easier for doctors 
to see different tissues in your body). Gadolinium is contrast material that causes 
some tumors to appear much brighter than normal tissue on MRI scans (these 
tumors may not be visible without gadolinium). The contrast material may be 
given to you in your arm through an intravenous catheter (a tiny tube inserted into 
a vein). You will then lie down on a narrow bed, which will be placed in a tunnel 
that is 6 feet long by 22 inches wide and open at each end. You will lie there 
quietly for about one hour, during which time you will hear a loud machine-like 
noise. The MRI scan is done in the radiology department and takes approximately 
an hour and a half to complete. 

The researchers will obtain blood and tissue samples to look at the biomarkers in your 
samples before receiving study drugs. These results will be compared to the biomarkers 
in blood and tissue samples obtained after you receive study drug, to see if the 
biomarkers in your samples changed after the study drug was given.
o
BLOOD DRAWING (5 tablespoons): The sample will be tested for biomarkers.

TISSUE BIOPSY: 

If leftover tissue can be obtained from a previous biopsy or surgery that 
was performed, you will not need to have a biopsy done.

If leftover tissue from a prior biopsy or surgery is not available, either an 
incisional/core biopsy (surgical procedure) or a fine needle aspiration 
(FNA) biopsy will be performed. The type of biopsy will be at the 
discretion of the study doctor and typically depends on the location of 
your tumor. 

As part of this study, we will obtain a small piece of tumor tissue using a 
special needle. This procedure will be done at the site where we can most 
easily get a piece of the tumor and the biopsy can involve the lungs, liver,

bone, lymph node, skin or other. The biopsy needle will be inserted into 
tumor tissue and a small piece of the tumor will be removed. 1-3 passes 
with this needle will be made. The tissue biopsy is used to confirm your 
diagnosis and make sure you are eligible to be in this research study. The 
tissue is also being used to help us determine if certain types of tumors 
might respond better to certain treatments.  This procedure takes about 30 
minutes.  You will sign a separate consent form for this procedure.  

INCISIONAL BIOPSY/CORE BIOPSY (surgical procedure): The doctor 
will use a local anesthesia on the skin to numb the area where a hollow 
needle (about the size of the tip of a ball-point pen) will be inserted.  Then 
the doctor will make a cut through the skin into the area of the tumor.  If a 
“punch biopsy” is done, a rounded knife is used to cut the through the 
skin.  The doctor will then remove a piece of the tumor by inserting the 
hollow needle one or more times into the tumor.  The doctor will then 
close the area of the biopsy with stitches.  You will sign a separate consent 
form for this procedure. This will take 15-30 minutes.

FINE NEEDLE ASPIRATION (FNA): This is a special type of biopsy.  
The doctor will insert a fine (very thin) needle through your skin and into 
your tumor and will remove a very small sample (less than ½ a teaspoon) 
of your tumor.  Either an ultrasound or CT scan will be used to guide the 
placement of the needle.  You will sign a separate consent form for this 
procedure. This procedure will take about 15-30 minutes.
During the main part of the study...
If the tests and procedures show that you can be in the main part of the study, and you choose to 
take part, then you will be given ruxolitinib and undergo the following tests and procedures. 
Ruxolitinib
Ruxolitinib will be taken by mouth every morning and every evening, with or without food, for 
14 to 21 days before your surgery. You will stop taking ruxolitinib after the morning dose on the 
day of your planned surgery. If there are logistical/scheduling issues that delay surgery, 
ruxolitinib may be taken for up to 28 days.

You will take 4 tablets in the morning and 4 tablets in the evening or 3 tablets in the 
morning and 3 tablets in the evening. Each tablet is 5mg so you will either take a total of 
40 mg or 30 mg daily. The amount you take will be based on the results of clotting tests 
performed on your blood samples. 

If you are not able to swallow the study tablets, ruxolitinib can be administered through a 
nasogastric or percutaneous gastrostomy tube (feeding tube) as follows:
o
Place three or four tablets, depending on the dosage amount you are assigned to 
take, in approximately 3 tablespoons of water and stir for approximately 10 
minutes.
o
Within 6 hours after the tablets have dissolved, it can then be administered 
through the feeding tube.

o
The tube should then be rinsed with approximately 5 tablespoons of water.

If you miss a dose or happen to vomit, do not take an additional dose, but take the next 
scheduled prescribed dose. 

You will keep a drug diary to record the doses of study drug taken and return all unused 
study drug to the study doctor

While taking the study drug you should avoid grapefruit, grapefruit juice, starfruit and 
Seville oranges because these can affect the amount of drug in your blood.
Pre-surgery (within 5 days of planned surgery):

History and physical examination

Repeat CT, PET-CT, or MRI scan for tumor measurements. This scan will be the same type 
that was done before you began the study drug.

Blood drawing (5 tablespoons):
o
Routine safety tests
o
Liver function tests
o
Clotting tests
o
Biomarker tests
When you are finished receiving ruxolitinib…
Day of Surgery:

Tissue samples will be collected at the time of your planned surgery for biomarker studies. 
The doctor performing the surgery or pathologist reviewing your specimens may set aside 
any leftover tumor material soon after it has been removed from your body. Your 
scheduled surgery will not be affected in any way by the collection of left-over tissue 
samples for research because the tissue collected for this research study will be obtained 
after your tumor tissue has already been removed from your body. The additional samples 
will not be collected if we think it will affect the sample needed for your clinical care.

How long will I be in the study?
You will be asked to take Ruxolitinib for 14-21 days prior to surgery. After you are finished 
taking Ruxolitinib, the study doctor will ask you to visit the office for follow-up exams for at 
least 4 weeks after surgery and 12 weeks after surgery for routine standard of care 
exams/procedures. 
Can I stop being in the study?
Yes. You can decide to stop at any time. Tell the study doctor if you are thinking about stopping 
or decide to stop. He or she will tell you how to stop your participation safely. 
It is important to tell the study doctor if you are thinking about stopping so any risks from the 
Ruxolitinib can be evaluated by your doctor. Another reason to tell your doctor that you are 
thinking about stopping is to discuss what follow-up care and testing could be most helpful for 
you.
The study doctor may stop you from taking part in this study at any time if he believes it is in 
your best interest, if you do not follow the study rules, or if the study is stopped.
What side effects or risks can I expect from being in the study?
You may have side effects while on the study. Everyone taking part in the study will be watched 
carefully for any side effects. However, doctors don't know all the side effects that may happen. 
Side effects may be mild or very serious. Your health care team may give you medicines to help 
lessen side effects. Many side effects go away soon after you stop taking ruxolitinib. In some 
cases, side effects can be serious, long lasting, or may never go away. 
You should talk to your study doctor about any side effects you experience while taking part in 
the study.
Risks and side effects related to ruxolitinib:
Ruxolitinib is indicated for the treatment of myelofibrosis (MF). Therefore, most of the studies 
measuring the safety of ruxolitinib were conducted with patients with MF. Patients with diseases 
other than MF (including healthy volunteers, polycythemia vera, multiple myeloma, prostate 
cancer and rheumatoid arthritis) who received ruxolitinib have had similar side effects. These 
side effects are more common in patients with myelodysplastic syndrome who received 
prolonged treatment with ruxolitinib. These side effects and risks are less common in patients 
treated for less time and for a different indication.

IRB EXPIRATION DATE: 02/29/2024


ICF 03/22/2023
PAGE 7 OF 14
              CC#16201
The most frequently reported side effects in patients with MF who have been treated with 
ruxolitinib are:
Likely (observed in greater than 30% of patients)

Anemia (low red blood cells)

Thrombocytopenia (low platelets) 
Less Likely (observed in 10-30% of patients)

Raised ALT (blood proteins that may indicate mild liver damage)

Bruising

Raised AST (blood proteins that may indicate mild liver damage)

Hypercholesterolemia (increase in cholesterol)

Neutropenia (low white blood cells)

Dizziness

Headache

Urinary tract infections
Rare (observed in less than 10% of patients) 

Weight gain

Flatulence

Herpes zoster (shingles)

Tuberculosis (<1%) – bacterial infection of the lungs

Progressive multifocal leukoencephalopathy (PML)(<1%) – a viral disease characterized 
by progressive damage or inflammation of the brain
Risks and side effects related to study procedures:

Blood drawing (venipuncture) risks: Drawing blood may cause temporary discomfort from 
the needle stick, bruising, infection, and fainting.

Electrocardiogram (EKG) risks: The EKG involves placing electrodes on the skin. You 
may experience an allergic reaction to the adhesive used to attach the electrodes to the skin. 
These symptoms are generally mild and clear up on their own. Please let your doctor know if 
you are aware of any allergies.

Radiation risks: This research study involves exposure to radiation from CT or PET/CT 
scans. Not all this radiation exposure is necessary for your medical care and is for research 
purposes only. The additional amount of radiation that you will receive as a result of 
participating in this study will be a maximum of approximately 12 mSv, which is equivalent 
to 4 times the yearly natural background of radiation in the US, which is 3 mSv (a mSv, or 
millisievert, is a measurement of radiation). In the event there is no tumor tissue available for 
analysis and tumor localization must be guided by CT, the additional radiation exposure 
would be a maximum of 14 mSv. In this case, the total radiation dose could be as high as 26 
mSv, equivalent to slightly less than 9 times the yearly natural background. This amount of 
radiation may involve a low risk of cancer. If you are pregnant or breast feeding, you

              CC#16201
SHOULD NOT participate in this study. If you have any questions regarding the use of 
radiation or the risks involved, please consult the physician conducting the study.

CT scan risks: CT scans involve the risks of radiation (see above). In addition, if contrast 
material (iodine dye) is used, there is a slight risk of developing an allergic reaction, from 
mild (itching, rash) to severe (difficulty breathing, shock, or rarely, death). The contrast 
material may also cause kidney problems, especially if you are dehydrated or have poor 
kidney function. The study doctors will ask you about any allergies or related conditions 
before the procedure. If you have any of these problems, you may not be allowed to have a 
CT scan.
Having a CT scan may mean some added discomfort for you. In particular, you may be 
bothered by feelings of claustrophobia when placed inside the CT scanner, or by lying in one 
position for a long time. If contrast material is used, you may feel discomfort when it is 
injected. You may feel warm and flushed and get a metallic taste in your mouth. Rarely, the 
contrast material may cause nausea, vomiting or a headache. 

PET/CT scan risks: The PET/CT involves exposure to radiation. The radiation exposure 
comes from a tracer which is a radioactive chemical injected into a vein in your arm. The 
tracer lets the doctor see how your cells are functioning. As with all injections, it may feel 
like a small sting and there may be possible bruising at the injection site. For some patients, 
having to lie still on the scanning table for the length of the procedure may cause some 
discomfort or pain. The radioactive solution does not remain in your system for a long period 
of time. See Radiation Risk.

MRI risks: Because the MRI machine acts like a large magnet, it could move iron-
containing objects in the MRI room during your examination, which in the process could 
possibly harm you. Precautions have been taken to prevent such an event from happening; 
loose metal objects, like pocket knives or key chains, are not allowed in the MRI room. If 
you have a piece of metal in your body, such as a fragment in your eye, aneurysm clips, ear 
implants, spinal nerve stimulators, or a pacemaker, you will not be allowed into the MRI 
room and cannot have an MRI. Having an MRI may mean some added discomfort for you. In 
particular, you may be bothered by feelings of claustrophobia and by the loud banging noise 
during the study. Temporary hearing loss has been reported from this loud noise. This is why 
you will be asked to wear earplugs. At times during the test, you may be asked to not 
swallow for a while, which can be uncomfortable.
Because the risks to a fetus from MRI are unknown, pregnant women must not participate in 
this study. 

Contrast agent (gadolinium) risks: A few side effects of gadolinium injection such as mild 
headache, nausea, and local pain may occur. Rarely (less than 1% of the time) low blood 
pressure and lightheadedness occurs. This can be treated immediately with intravenous fluids. 
Very rarely (less than on in one thousand), patients are allergic to gadolinium. These effects 
are most commonly hives and itchy eyes, but more severe reactions have been seen which 
result in shortness of breath.
IRB NUMBER: 17-21705
IRB APPROVAL DATE: 04/14/2023
IRB EXPIRATION DATE: 02/29/2024


ICF 03/22/2023
PAGE 9 OF 14
              CC#16201
Patients with severe kidney disease sometimes have a bad reaction to gadolinium contrast. The 
condition is called nephrogenic systemic fibrosis (NSF). It can cause skin to tighten or scar 
and can damage internal organs. Sometimes it can be life threatening. There are no reports of 
NSF in patients with normal kidney function. Before you have a MRI scan requiring an 
injection of gadolinium contrast, you will have a blood test in order to check the function of 
your kidneys. Based on your medical history and the results of the test, a doctor will decide 
whether it is safe for you to undergo the MRI scans.

Drug Interaction Risks: Ruxolitinib taken in combination with other medicines may be 
associated with other risks that are unknown at this time. Although there is limited 
information on how ruxolitinib might interact with other medications, it is important to share 
with your study doctor any medications (prescription, over-the-counter, and herbal 
supplements) that you are taking.

Reproductive risks: You should not become pregnant or father a baby while on this study 
because the drugs in this study can affect an unborn baby. Women should not breastfeed a 
baby while on this study. It is important to understand that you need to use birth control 
while on this study. Check with your study doctor about what kind of birth control methods 
to use and how long to use them. Some methods might not be approved for use in this study. 
A pregnancy test will be required prior to starting the study.

Tumor Biopsy: The biopsy has small but serious risks. While we make every effort to 
minimize the pain related to the procedure, the procedure is usually uncomfortable and 
sometimes painful. Wherever the biopsy is done in your body, it can lead to bleeding in that 
area, damage of organs near where the biopsy is done, or infection. While it is uncommon, 
sometimes bleeding or pain from the biopsy will require you to stay overnight in the hospital 
or require you to go to the operating room to control any bleeding. We check your laboratory 
values before the biopsy to make sure that the procedure is as safe as possible and to 
minimize your chance of having a complication. Additionally, if the biopsy involves the 
lungs, it can cause the lungs to deflate and if this occurs, you might require treatment to 
correct this.  We try to take as little tissue as possible when we do the biopsy, and this means 
that sometimes the biopsy procedure can be unsuccessful and require a repeat biopsy to get 
enough tissue. Other potential risks will be described to you and discussed with you by 
doctors who conduct these biopsies.

Fine Needle Aspiration (FNA): The general risks associated with this procedure are pain, 
discomfort, infection, and bleeding.  If it is necessary for you to have a biopsy, the exact risks 
associated with the procedure you will be receiving will be discussed with you. 

Safe Handling of Medications: Handling ruxolitinib and having contact with any urine, 
feces or vomit from patients receiving ruxolitinib may pose some risk to you and your 
caregivers. To avoid exposure to ruxolitinib and any associated risks, you and your family 
members/caregivers will be educated by a member of the study team on how to safely handle 
ruxolitinib, properly dispose of ruxolitinib, and how to clean products that may be 
contaminated with ruxolitinib.

Genetic Testing Confidentiality Risks: There is a risk someone could get access to the 
personal information in your medical records or other information researchers have kept

about you. Someone might be able to trace this information back to you. The researchers 
believe the chance that someone will identify you is very small, but the risk may change in 
the future as people come up with new ways of tracing information. In some cases, this 
information could be used to make it harder for you to get or keep a job. There are laws 
against misuse of genetic information, but they may not give full protection. The researchers 
believe the chance these things will happen is very small, but cannot promise that they will 
not occur.

Unknown Risks: The experimental study drug may have side effects that no one knows 
about yet. The researchers will let you know if they learn anything that might make you 
change your mind about participating in the study.

For more information about risks and side effects, ask your study doctor.
Are there benefits to taking part in the study?
Taking part in this study may or may not make your health better. While doctors hope 
Ruxolitinib will be more useful against cancer compared to the usual treatment, there is no proof 
of this. We do know that the information from this study will help doctors learn more about 
Ruxolitinib as a treatment for cancer. This information could help future cancer patients.
What other choices do I have if I do not take part in this study?
Your other choices may include:

Getting treatment or care for your cancer without being in a study. 

Taking part in another study.

Getting no treatment.
Please talk to your doctor about your choices before deciding if you will take part in this study.
How will my specimens and information be used?
Researchers will use your blood and tissue specimens and information to conduct this study. 
Once the study is done using your specimens and information, we may share them with other 
researchers so they can use them for other cancer studies in the future. We will not share your 
name or any other personal information that would let the researchers know who you are. We 
will not ask you for additional permission to share the de-identified information and specimens.
Your blood and tissue specimens will be stored in a repository, also called a ‘tissue bank’, at 
UCSF. The manager of tissue bank and select tissue bank staff members will have access to your 
specimens and information about you, but they will not release any identifying information about 
you to researchers using your specimens. We may give your specimens and certain medical 
information about you (for example, diagnosis, blood pressure, age if less than 85) to other 
scientists or companies not at UCSF, including to an unrestricted or controlled-access 
government health research database, but we will not give them your name, address, phone

number, or any other identifiable information. Your specimens and information will be kept 
indefinitely until they are used up or destroyed. 
Research results from these studies will not be returned to you and will not be put in your 
medical record. The research will not change the care you receive.
Researchers may use your blood and tissue specimens to look at all of your DNA (this is called 
“whole genome sequencing”. DNA contains information that determines things like eye color, 
height, or disease risk that are passed on from parent to child. Genetic information (also known 
as genotype data) and the medical record data (also known as phenotype data) may be shared 
broadly in a coded form for future genetic research or analysis. 
Donating data and specimens may involve a loss of privacy, but information about you will be 
handled as confidentially as possible. Study data will be physically and electronically secured. 
As with any use of electronic means to store data, there is a risk of breach of data security. 
Genetic information that results from this study does not have medical or treatment importance at 
this time. However, there is a risk that information about taking part in a genetic study may 
influence insurance companies and/or employers regarding your health. Taking part in a genetic 
study may also have a negative impact or unintended consequences on family or other 
relationships. It is possible that future research could one day help people of the same race, 
ethnicity, or sex as you. However, it is also possible through these kinds of studies that genetic 
traits might come to be associated with your group. In some cases, this could reinforce harmful 
stereotypes.
There will be no direct benefit to you from allowing your specimens and data to be kept and used 
for future research. However, we hope we will learn something that will contribute to the 
advancement of science and understanding of health and disease. If your specimens, the data or 
any new products, tests or discoveries that result from this research have potential commercial 
value, you will not share in any financial benefits. 
If you decide later that you do not want your information to be used for future research, you can 
notify the investigator in writing at,

and any remaining data will be destroyed.  However, we cannot retract any data has been shared 
with other researchers.
How will information about me be kept confidential?
Participation in research involves some loss of privacy. We will do our best to make sure that 
information about you is kept confidential, but we cannot guarantee total privacy. Some 
information from your medical records will be collected and used for this study. If you do not 
have a UCSF medical record, one will be created for you. Your signed consent form and some of 
your research tests will be added to your UCSF medical record. Therefore, people involved with

your future care and insurance may become aware of your participation and of any information 
added to your medical record as a result of your participation. Study tests that are performed by 
research labs and information gathered directly from you by the researchers will be part of your 
research records and may be added to your medical record. Your personal information may be 
given out if required by law. If information from this study is published or presented at scientific 
meetings, your name and other personal information will not be used.
Organizations that may look at and/or copy your medical records for research, quality assurance, 
and data analysis include:

The University of California

Incyte pharmaceuticals

The National Cancer Institute (NCI) and other government agencies, e.g., the Food and 
Drug Administration (FDA), involved in keeping research safe for people. 
What are the costs of taking part in this study?
Incyte is supplying ruxolitinib at no cost to you. 
Two types of procedures will be done during this study. Some are part of your standard medical 
care and others are only for research. You or your insurer will be billed for the standard medical 
care. You will be responsible for your co-pays, deductibles, and any other charges that your 
insurer will not pay. Any procedures done only for research will not be charged to you or your 
insurer. There is a possibility that your insurer may not cover standard medical care costs 
because you are in a research study or because you are receiving medical services out of 
network.
Before you agree to be in this study, you may want to contact your healthcare payer/insurer to 
see if your plan will cover the costs required as part of your participation. You may request 
more information about the costs of participating in this study and discuss this with the study 
team.
If you have any questions, your doctor and the study team will be able to provide you with 
answers.
