Phase IB Feasability Trial of Paclitaxel/Carboplatin + Galunisertib (a Small Molecular 
Inhibitor of the Kinase Domain of Type 1 TGF-β Receptor) in Patients with Newly 
Diagnosed, Persistent or Recurrent Carcinosarcoma of the Uterus or Ovary
Principal Investigator: Kathleen Moore, MD
This is a clinical trial, a type of research study.  Your study doctor 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 taking part.  You have the choice not to participate.   You may discuss your 
decision with your friends, family and doctors.  If you have any questions, you can ask your study 
doctor for more information at any time. 
This study is being conducted by the University of Oklahoma Stephenson Cancer Center. Lilly 
pharmaceutical company is providing the study medicine, galunisertib, free of charge.
Why Have I Been Asked To Participate In This Study?
You are being asked to take part in this study because you have a form of uterine or ovarian cancer 
that requires additional medical treatment.  Medicine that targets cancer cells is referred to as 
“chemotherapy.” 
Why Is This Study Being Done? 
The usual treatment for your cancer is a combination of two chemotherapy medicines, carboplatin 
and paclitaxel.  Even with this treatment, many women with this type of cancer either do not have 
their cancer go away entirely or have their cancer come back.  Galunisertib is a new medicine that 
works against a part of the tumor that is thought to play a role in allowing your cancer type to 
become more aggressive. 
The purpose of this study is to find out if the addition of the new medicine, to the paclitaxel and 
carboplatin, is safe in patients with this type of cancer.  We will collect information about any side 
effects and how you feel with the three medications.  We will also look to see if the medicine is 
helpful in shrinking cancers, keeping them from growing or spreading, or helping patients live 
longer.
We are also interested in collecting a piece of your tumor tissue, either from a recent surgery or 
new biopsy. It will be used to help understand why this treatment might help.  Some patients will 
have blood drawn 5 times to check the levels of the drug in your bloodstream.
What is the Status of the Drugs involved in this study?
Galiunisertib is an investigational medicine. An investigational medicine is one that has not yet 
been approved by the US Food and Drug Administration (FDA).

Carboplatin and paclitaxel are approved by the US Food and Drug Administration (FDA) for 
treatment of your cancer.
How Many People Will Take Part In The Study?
About 36 people will be in this study. All participants will be at this location.
What Is Involved In The Study?
Before you begin the study
You will need to have the following exams, tests or procedures to find out if you can be treated in 
the study.  These exams, 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.

Doctor’s visit with examination to include a pelvic examination

Blood work to measure blood counts, blood salt levels, and how well your liver and kidneys 
are working

A pregnancy test if you are capable of becoming pregnant

Urinalysis (examination of urine)

CT scan or MRI of the chest, abdomen and pelvis to measure your tumor
You will need to have the following tests as part of the study. The following exams are not standard 
of care:

Possible tumor tissue biopsy
During the study 
If the exams, tests and procedures show that you can be treated in the study, and you choose to 
take part, then you will need the following tests and procedures.  They are part of regular cancer 
care. 

Doctor’s visit with examination to include a pelvic examination every treatment cycle 
(typically every 4 weeks)

Blood tests to measure blood counts, blood salt levels, and how well your liver and kidneys 
are working (as often as once weekly during combination treatment then monthly during 
maintenance treatment)

Urinalysis (examination of urine) done once every treatment cycle (typically every 4 
weeks)

Repeat CT scans every other cycle (typically every 8 weeks) during combination treatment 
then every 4 cycle during maintenance treatment.
You will have the following tests that are not part of regular cancer care and are being done only 
because you are in this study:

Possible blood draws to monitor the galunisertib levels in the blood

Possible tumor tissue biopsy after first cycle if your disease is still measurable
You will receive treatment with paclitaxel and carboplatin by vein (IV) on day 1.  On days 4-17 
of the cycle, you will take the study pill, twice a day by mouth.  On days 17-28 of cycle, you will

not have any medicine.  On day 29, if your oncologist feels you may safely continue treatment, 
you will begin a new 28 day cycle.  After you have had 4 cycles of treatment, if you do not have 
any active cancer, your physician may discuss continuing treatment with the study pill, 
galunisertib, alone for up to 1 year.  
Note: You may receive treatment with Docetaxel and carboplatin by vein (IV) on day 1 if you are 
allergic to paclitaxel.
After your treatments are completed:
To monitor your well-being and the status of your cancer, you will have these tests and procedures 
that are part of regular cancer care:

Doctor’s visit with examination which may include pelvic examination 
o
every 3 months for two years
o
then every 6 months for three years
o
then every year thereafter 

Blood work if your physician feels they are necessary for monitoring

CT scan or MRI 
Study Chart
You will receive a combination of three medications every 4 weeks in this study. This 4-week 
period of time is called a cycle.  The cycle will be repeated until either

your cancer grows or spreads

the medications cause you too many side effects

or your cancer has gone away on a cat scan and you have received at least 4 cycles.

Study Plan
Another way to find understand what will happen to you during the study is to read the chart 
below.  Start reading at the left and continue across the chart, following the lines and arrows.
How Long Will I Be In The Study? 
You will be asked to take the study medicines as long as there is evidence that your tumor is not 
growing or spreading and you are not having any bad side effects.  If there is no cancer on your 
scans after 4 cycles of treatment (~ 4 months), you may stop the two medicines by vein and 
continue with the medicine by mouth alone for one more year.
After you have finished treatment, the study doctor will follow up your survival status through 
phone check in every 3 month for two years from date of registration.  After this, we would like to 
keep track of your medical condition for the rest of your life by calling you once a year to see how 
you are doing. Keeping in touch with you and checking on you every year helps us look at the 
long-term effects of the study medicines. 
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 safely.

It is important to tell the study doctor if you are thinking about stopping, so any risks from the 
study treatment can be evaluated by your doctor.  Another reason to tell your doctor that you are 
thinking about stopping is to discuss what other care and testing could be most helpful for you.
There may be situations under which you will not receive any more study treatments even though 
you want to.

The doctor feels that it is safest for you.

Your cancer or medical illnesses worsen.

New information becomes available that suggests another treatment would be better for 
you

You do not follow study requirements.

The study is stopped by the sponsor.
What Are The Risks of 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 the medications.  In some 
cases, side effects can be serious because they can last a long time, may never go away, may result 
in hospitalization, may be life-threatening, or even cause death.
You should talk to your study doctor about any side effects that you have while taking part in the 
study.
Risks and side effects related to Paclitaxel include those which are:
Likely (>10%):

Low white blood cell counts - this may make you more open to infection 

Low platelet count - this may make you bruise more easily and bleed longer if injured 

Low red blood cell count which may cause tiredness, shortness of breath or fatigue

Numbness and pain of the hands and feet that sometimes worsens with additional treatment 
and may not disappear after the drug is stopped. This may lead to difficulty walking, 
buttoning clothes, etc.

Hair loss

Muscle weakness and muscle loss

Muscle and joint aches
Less likely, but potentially serious (≤10%):

A slowing of the heart rate (a slow pulse is not harmful; however if you should develop 
any other irregularities in heart rate during treatment, an EKG and other tests may be 
required.)

Irregular heartbeats 

Heart attack

Nausea and/or vomiting 

Diarrhea 

Sores in the mouth or throat (that can lead to difficulty swallowing and dehydration)

Risks and side effects related to Galunisertib
Given that this medicine is new, not all of the potential side effects are known.  The medicine has 
been used in other small numbers of patients with few side effects.  Possible side effects that may 
occur given what we know about the medicine are listed below.
Possible Risks

Blood clots in legs or lung

Decreased ability to fight infections

Increased size of the aorta (blood vessel) which can lead to the vessel tearing

Low blood pressure

High heart rate

Heart damage causing the heart to beat less effectively

Over reactive immune system which leads to inflammation of the lungs, bowel, joints, or 
other parts of the body

Birth defects if taken during pregnancy

Low platelet count - this may make you bruise more easily and bleed longer if injured
Additional Risks or Discomforts
Tumor Biopsy:
If you undergo a tumor biopsy, there may be side effects such as:

Pain

Bruising

Bleeding

Infection
The risks may vary depending on the location of the tumor mass being biopsied. Mild pain is 
related to the procedure itself, occurs in most patients, and is typically transient and well-controlled 
by the administration of pain medication, if necessary. The risk of infection is low. If infection 
does occur, antibiotics will be administered. The risk of bleeding with these biopsies is also 
typically low, but it is not known if treatment with Galunisertib may increase the risk of bleeding. 
Your study doctor can specifically discuss the risk of bleeding in your particular situation with 
you.
Reproductive Risks: You must not be and should not become pregnant nor breast-feed an infant 
while on this study.  Taking the study medicine while you are pregnant or breastfeeding may 
involve risks to an unborn baby, including birth defects which are currently unforeseeable. It is 
important you understand that if you could become pregnant, you must use birth control 
consistently while on this study and for one month after stopping the medicines. In order to 
reduce your risk of pregnancy, you or your partner should use one or more of the acceptable 
methods of birth control listed below, always while you are in this study.

Acceptable methods of birth control include:

An approved birth control pill

Intra-uterine device (IUD)

Hormone implants  

Depo-Provera

Diaphragm with spermicidal gel or condoms

Birth control patch

Birth control ring

Tubal ligation, hysterectomy or vasectomy

Abstinence
If you are already using a method of birth control, check with the study doctor to make sure it is 
safe for this study.  Certain drugs may interact with some methods of birth control and reduce how 
well they work. You should inform the study doctor of all medicines (prescription and over-the-
counter) that you are currently taking or begin taking during the study.
If you become pregnant or suspect that you are pregnant during this study, immediately tell one of 
the study staff.  If you become pregnant or suspect that you are pregnant while on this study, tell 
the study doctor immediately; the study doctor will perform a pregnancy test.  The study drug may 
be stopped until the result of the pregnancy test is known.  If you are pregnant, you may be asked 
to permanently stop the study.  The study doctor will assist you in getting obstetrical care at your 
cost.  Payment for all aspects of obstetrical, child, or related care will be your responsibility.
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 the addition 
of the study medicine to chemotherapy will improve the benefits of treatment, there is no proof of 
this yet. Information from this study will help doctors learn more about adding the study medicine 
to chemotherapy as a treatment for this type of cancer. This information could help future cancer 
patients.
What Other Options Are There?
Your other choices may include:

Getting treatment for your cancer without being in a study which may include 
chemotherapy, radiation, or a combination of chemotherapy and radiation

Taking part in another study

Getting no anti-cancer medicine and instead taking only medicines to control the symptoms 
of your cancer (palliative care).

Getting no care at this time
Talk to your doctor about your choices before you decide if you will take part in this study.
What About Confidentiality?
Efforts will be made to keep your personal information confidential. You will not be identifiable 
by name or description in any reports or publications about this study. We cannot guarantee

included that reveals your identity. In a few rare situations, federal or state law requires disclosure 
of personal information. 
What Are the Costs?
You and/or your health plan/ insurance company will need to pay for some of the costs of treating 
your cancer in this study, including the cost of managing the side effects of therapy.  Some health 
plans will not pay these costs for people taking part in studies.  Check with your health plan or 
insurance company to find out what they will pay for.  You will be responsible for paying any 
deductibles, co-insurance, and co-payments as required under the terms of your insurance plan(s). 
Taking part in this study may or may not cost your insurance company more than the cost of getting 
regular cancer treatment. 
Paclitaxel and carboplatin are both FDA-approved, commercially available drugs. You or your 
insurance company will be responsible for the costs of your chemotherapy.
Galunisertib is an investigational drug and will be provided free of charge by Lilly Oncology.  The 
heart tests which are specifically needed to check for side effects of this medicine will be covered 
under the study.
You will not be paid for taking part in this study.  The institution receives payment that covers 
some, but not all, of the costs of the study.

GENERAL INFORMATION ABOUT THE COLLECTION AND USE OF SPECIMENS 
FOR RESEARCH
You are being asked to allow samples from your tumor and blood to be submitted and used in 
research.  Such bodily materials are referred to as specimens and are very important in helping 
doctors and scientists learn more about caring for and treating people with cancer and other 
diseases. The use of specimens in scientific research can also help doctors and scientists understand 
why some people develop cancer and others don’t, and why some people have cancers that respond 
or don’t respond well to current therapies, for example.
The research that may be done with your specimens is not designed specifically to help you, but it 
may help others with cancer or other diseases in the future. Reports about research done with your 
specimens will not be given to you or your doctor, or be put in your health record. The research 
will not have an effect on your care. 
When research is performed on specimens connected with clinical information about the person, 
including the person’s disease and how the person responds to treatment, doctors and scientists 
can specifically study how to prevent, detect, treat and cure cancer and other diseases, or how to 
predict response to therapy, toxicities, recurrence and overall survival.

The University uses procedures designed to protect your privacy and confidentiality. The chance 
that information from your health records would be incorrectly released is very small, but you 
should be aware of this risk.  To protect your privacy and confidentiality, the research investigators 
that study your specimens will never be given your name, address, phone number, Social Security 
number or any other personal information. In addition, your specimens will never be labeled with 
your name or other type of personal identifier. Your specimens will be labeled with a unique series 
of letters and numbers in order to keep track of the specimens.  Research investigators receive 
specimens labeled only with these codes.
Your specimens will be used for research purposes and will not be sold.  However, the research 
may help to develop new products and therapies in the future that could be patented and licensed. 
In any event, there are no plans to provide you with any direct financial compensation. 
If you agree now that your tumor specimen and/or blood specimens can be submitted and used for 
this research study and/or future research, you can change your mind at any time. At that time, 
please contact the staff at your treating institution, typically your doctor or nurse, and tell them 
that you have changed your mind about allowing your specimens to be used for research. 
SPECIFIC INFORMATION FOR THIS RESEARCH STUDY 
Requirements 
We would like to have your permission to have some of your tumor, if available, from a recent 
surgery. If you have not recently had surgery or your tissue sample is not enough, we are requesting 
you undergo a biopsy to obtain a small piece of your tumor. If you still have measurable disease 
after first cycle, you will undergo a second biopsy. The reason for this is to study your tumor and 
the effect of this treatment on it.
We are also asking some participants to provide two teaspoons of blood at 6 time points to better 
understand how long the study medicine stays in your body when taken with this chemotherapy.  
These include 

3 times on day 4 of cycle 1 (first day of the medication by mouth)

Once on day 8 of cycle 1

Once on day 15 of cycle 1
Agreement for additional procedures and release of tumor samples
When you agree to participate in this study, the study team will determine if the additional blood 
work or biopsy is needed.
1. Do you give permission for your blood to be collected for these additional studies?

SPECIFIC INFORMATION FOR FUTURE RESEARCH
The last section of the consent will ask you to decide whether your tumor samples, if still available 
after completion of this research study, can be used for future cancer research or for research for 
health problems other than cancer.  We will also ask your permission to use the clinical information 
we collect about you as part of your participation in this research study to be utilized for future 
research that will use your specimens.  Next, we will ask for permission to contact you in the future 
to participate in more research. 
If you agree to allow your specimens to be used for future research, there is a chance that your 
specimens may be used to study changes in genetic material that are passed on in families or that 
are not passed on in families but are either natural changes or influenced by environment and 
lifestyle.  These tests can focus on a section of genetic material (DNA), genetic material packaged 
into chromosomes or examine all of the genetic material called the whole genome. The results can 
then be studied to identify changes in genetic material that influence the development of diseases 
including cancer or the effectiveness of specific treatments. Reports of this research done in your 
specimens will not be given to you or your doctor, and will not be put in your health record.  
Risks of genetic testing:
A Federal law, called the Genetic Information Nondiscrimination Act (GINA), generally makes it 
illegal for health insurance companies, group health plans, and most employers to discriminate 
against you based on your genetic information.  
This law generally will protect you in the following ways: 

Health insurance companies and group health plans may not request your genetic 
information that we get from this research.

Health insurance companies and group health plans may not use your genetic information 
when making decisions regarding your eligibility or premiums. 

Employers with 15 or more employees may not use your genetic information that we get 
from this research when making a decision to hire, promote, or fire you or when setting the 
terms of your employment. 
Be aware that this Federal law does not protect you or your family against genetic discrimination 
by companies that sell life insurance, disability insurance, or long-term care insurance.  Also, 
GINA does not prohibit discrimination of individuals with a genetic disorder that has been 
diagnosed.  However, in order to do everything possible to keep this from happening, the results 
of this test will NOT be given to anyone outside the study staff. This means that it will not be made 
available to you, your family members, your private physician, your employer, your insurance 
company or any other party as allowed by law.

Title of Research Project: Phase IB Feasability Trial of Paclitaxel/Carboplatin + Galunisertib (a Small 
Molecular Inhibitor of the Kinase Domain of Type 1 TGF-β Receptor) in Patients with Newly 
Diagnosed, Persistent or Recurrent Carcinosarcoma of the Uterus or Ovary
Leader of Research Team: Kathleen Moore, MD
Address: 800 NE 10th Street, Oklahoma City, OK 73104
Phone Number:  405 271-8707
Purpose of Repository: To determine if Galunisertib in combination with Carboplatin and Paclitaxel is 
helpful in treating carcinosarcoma of the uterus or ovary. Your samples may also be used in future 
research to help patients with this type of cancer. 
If you decide to participate in this research project, which may also include a Research Repository, 
University of Oklahoma Health Sciences Center (OUHSC) researchers may use, keep, or share 
information about you that identifies you (protected health information) for their research. Protected 
health information will be called PHI in this document.
What is a Research Repository?  A Research Repository (data bank) is a collection of information 
from the health and medical records of many individuals and can sometimes include identifiable 
tissue specimens. The Repository (data bank) shares the information with researchers who study 
medical conditions and diseases. 
The Repository (data bank) includes codes that identify each person whose information is collected.  
However, the Repository does not share information with researchers unless the researchers promise 
to keep the information confidential.
PHI To Be Used or Shared.  Government rules require that the researchers get your permission 
(authorization) to use or share your PHI. If you give permission, the researchers could use or share 
with the people identified in this authorization, any PHI related to this research from your medical 
records and from any test results.  This includes: personal information that you provide including 
1 Protected Health Information includes all identifiable information relating to any aspect of an individual’s 
health whether past, present or future, created or maintained by a Covered Entity.

your age, gender, etc., the results of procedures and tests, information about your response to 
treatments, and other medical information relating to your participation in the study.  Information 
used or shared will also be or might be personal information such as your name, address, telephone 
number, date of birth, race, government-issued identification number, medical records, and charts 
relating to any tests or procedures outlined in the informed consent form.   
Purposes for Using or Sharing PHI. If you give permission, the researchers will use your PHI to: 
conduct the research and procedures described in the Informed Consent Form and as otherwise 
permitted by the Informed Consent Form.
Other Use and Sharing of PHI. If you give permission, the researchers could also use your PHI to 
develop new procedures or commercial products. They could share your PHI with the research 
sponsor, the OUHSC Institutional Review Board, inspectors who check the research, and 
government agencies like the Food and Drug Administration (FDA) and the Department of Health 
and Human Services (HHS). The researchers may also share your PHI with: Lilly Oncology.
Confidentiality. Although the researchers will report their findings in scientific journals or meetings, 
they will not identify you in their reports. The Repository and the researchers will try to keep your 
information confidential, but confidentiality cannot be guaranteed. The law does not require everyone 
who might see your information covered by this document to keep it confidential, so it might be 
released to others and federal law may no longer protect it.  
YOU UNDERSTAND THAT YOUR PROTECTED HEALTH INFORMATION MAY 
INCLUDE INFORMATION REGARDING A COMMUNICABLE OR NONCOMMUNICABLE 
DISEASE.
Voluntary Choice. The choice to give OUHSC researchers and the Repository permission to keep or 
share your PHI for their research is voluntary.  It is completely up to you.  No one can force you to give 
permission.  However, you must give permission for the Repository to use or share your private health 
information if you want to participate in the Research Repository.
Refusing to give permission will not affect your ability to get usual treatment or health care unrelated to 
this study from OUHSC.  
Canceling Permission.  If you give the Repository or OUHSC researchers permission to use or 
share your PHI, you have a right to cancel your permission whenever you want. However, canceling 
your permission will not apply to information that the Repository or researchers have already used or 
shared or to information necessary to maintain the reliability or integrity of the research.
End of Permission. Unless you cancel it, permission for OUHSC researchers and the Repository to 
use or share your PHI for their research will never end.  
Contacting OUHSC.  You may find out if your PHI has been shared, get a copy of your PHI, or 
cancel your permission at any time by writing to:
Privacy Official                                                    or Privacy Board

1 HYPOTHESES AND OBJECTIVES 
1.1 
Objectives 
1.1.1 Primary 
1. To determine the feasibility of delivering 4 cycles of carboplatin/paclitaxel (CT) in 
combination with galunisertib (GB) to patients with gynecologic carcinosarcoma 
1.1.2 Secondary 
1. To determine the frequency and severity of adverse events as assessed by the CTCAE v4 
2. To determine the progression free survival (PFS) and overall survival (OS) of patients 
receiving combination CT + GB. 
3. To ascertain the pharmacokinetic profile of GB when given in a combination regimen with 
CT. 
1.1.3 Exploratory/Correlative 
1. To determine if H-score criteria (% of cells and intensity) of IHC nuclear phospho-smad2/3 
levels after cycle 1 are associated with response to galunisertib therapy. 
2. To evaluate the mRNA expression Level of EMT markers along with the TGFβ1 in the GB 
pre-treated and post-treated patient samples 
 
1.2 
Endpoints 
1.2.1 Primary 
1. Completion of 4 cycles of CT + GB- completion of a cycle will be defined as receiving 
both carboplatin/paclitaxel and taking ≥75% of the doses of GB for the cycle. 
1.2.2 Secondary 
1. Adverse event occurrence and grade 
2. PFS- duration of time from enrollment to RECIST progression or death from any cause, 
censored at last disease assessment or loss to follow-up; and OS – duration of time from 
enrollment to death from any cause, censored at date last known alive or loss to follow-up 
3. Galunisertib plasma concentrations levels on Cycle 1 day 4, 8 and cycle 2 day 1 
1.2.3 Exploratory 
1. Correlate H-score of IHC nuclear phospho-smad2/3 before GB therapy with response rate 
(complete response + partial response). 
2. Compare H Score of psamd2/3 staining in pretreated and post-treated patient tumor 
samples then correlate with the patient therapy response 
2 BACKGROUND AND RATIONALE 
Uterine Carcinosarcoma (UCS) is a rare, aggressive malignancy accounting for 5% of uterine 
cancers. It is defined by the presence of both epithelial (carcinomatous) and mesenchymal 
(sarcomatous) malignant cells [1]. Carcinosarcomas (CS) have been reported in a variety of organ 
sites including the ovary, fallopian tube, peritoneum, prostate, and breast, with uterine origin being 
most common. The epithelial component of UCS may include endometrioid elements but

frequently has high grade features (serous, clear cell, grade 3). Clinically, UCS tumors have a high 
incidence of extra-uterine spread at diagnosis and high rates of recurrence manifesting as poor 
progression-free survival (PFS) and overall survival (OS)[2]. 
Standard of care treatment for patients with UCS includes hysterectomy, bilateral salpingo-
oophorectomy, and lymph node dissection. Adjuvant chemotherapy has emerged as the most 
active treatment. The GOG conducted a series of drug development trials with the goal of defining 
active regimens. Ifosfamide, cisplatin, and paclitaxel were identified as the most active single 
agents. Combination regimens further improved response rates, with variable effects on PFS and 
OS [3, 4].  A phase III trial comparing ifosfamide +/- paclitaxel in patients with advanced/recurrent 
UCS demonstrated an improved response rate (RR) (45% vs 29%), median PFS (5.8 vs 3.6 mo), 
and median OS (13.5 vs 8.4 mo) with the combination regimen [4]. A subsequent phase II trial of 
paclitaxel and carboplatin reported a RR of 54% (13% complete response), median PFS of 7.6 
months, and median OS of 14.7 months [5]. A subsequent phase III trial comparing ifosfamide + 
paclitaxel to carboplatin + paclitaxel is ongoing. In a parallel trial, stage I-IV patients with no 
residual disease were randomized to ifosfamide + cisplatin or whole abdominal radiation therapy 
[5]. The results demonstrated that a 22% reduction in the relative risk of recurrence and a 29% 
reduction in the risk of death with chemotherapy. In addition, the results of EORTC study 55874 
(observation vs pelvic radiation for stages I-II UCS and leiomyosarcoma) demonstrated better 
local control without impact on survival [6]. Despite these treatment improvements, <30% of 
patients with optimally resected, stage III-IV disease remain free of progression at 3 years [5]. For 
patients with bulky advanced/recurrent disease, ~15% of patients remain free of progression at 2 
years, and only 20% survive 2 years[7]. Improvement upon existing treatments is greatly needed.  
Historically, UCS was combined with other uterine sarcomas for treatment selection and clinical 
trial eligibility. There is increasing recognition that UCS are not sarcomas, but an extreme 
manifestation of de-differentiated endometrial cancer (EC). Several hypotheses have been 
advanced to explain the histiogenesis of UCS. One possible explanation for the phenotypic 
changes is that it may represent a model of epithelial-mesenchymal transition (EMT). EMT is a 
process whereby epithelial cells lose polarity and cell-cell contacts, have remodeled cytoskeletons, 
and acquire the ability to migrate [8-10]. These changes are associated with the activation of a 
mesenchymal like gene expression profile. Mesenchymal cells are able to detach, penetrate the 
basement membrane, infiltrate, and metastasize. Primary tumor cells undergo EMT to acquire 
invasive/metastatic capacity. In addition, EMT induces cancer stem-like properties and confers 
drug resistance to tumor cells [11, 12].  
A few studies have evaluated the role of EMT in uterine carcinosarcomas. Saegusa and colleagues 
compared 14 cases of UCS to 13 cases of endometrial cancers and demonstrated the complete 
shutdown of E-cadherin expression in the mesenchymal elements[13]. In addition pAkt and 
nuclear B-catenin levels were increased in mesenchymal cells. Romero-Perez and colleagues 
compared tumor DNA microarrays between 15 UCS and 23 EC samples and demonstrated changes 
in the expression of genes modulating EMT including the AT-hook 2 gene (embryonic nuclear 
factor that mediates EMT in some tumor models) and overexpression of HMGA2 gene (which 
favors EMT by cooperating with the TGF-beta/Smad pathway) [14].  
UCS represents an ideal model to study EMT. Morphologically, epithelial cells undergo EMT as 
reflected in the appearance of sarcomatous/mesenchymal populations of cells within UCS. The 
mesenchymal cells demonstrate many of the hallmarks (clinically and by IHC) of EMT. Metastatic

disease demonstrates epithelial components, perhaps suggesting the activation of mesenchymal to 
epithelial (MET) transition. However, the mechanisms underlying this EMT transformation are 
currently unknown.  
Several candidates that may interrupt EMT and inhibit cancer stem-like cells (CSC) have been 
identified [10, 15, 16]. Among several growth factors that can act as inducers of EMT, 
transforming growth factor beta (TFG-β) has been shown to play an important role in cancer 
progression and metastasis [15, 17-19]. TGFβ is a multifunctional cytokine that regulates EMT 
and suppresses growth and proliferation in epithelial cells. Aberrations in TGF-β signaling occur 
frequently during tumorigenesis allowing cancer cells to proliferate, invade, and metastasize 
beyond their tissue of origin. Active TGFβ binds to the TGFβ type II receptor subunit (TGFβR-
II), which then recruits and activates the type I receptor subunit (TGFβR-I). This active receptor 
complex phosphorylates and activates the receptor-activated Smads which then form complexes 
with Smad4, and translocates to the nucleus to modulate specific target gene expression[20].  Mani 
and colleagues were among the first to report a link between EMT and the acquisition of epithelial 
stem cell properties where TGFβ treatment of breast cancer stem cells initiated EMT and 
concomitant acquisition of tumor initiating and self-renewal properties[21]. TGFβ has also been 
shown to modulate E-cadherin expression and induce reversible epithelial to mesenchymal trans 
differentiation in epithelial cells [22].  
Komiyama and colleagues have reported that expression of TGFß1 and its receptors is associated 
with biological features of ovarian cancer and cancer sensitivity to paclitaxel/carboplatin [23]. 
Tissues of the primary tumor were collected from 24 patients with ovarian cancer, primary 
peritoneal cancer, or fallopian tube cancer who had undergone surgery and chemotherapy with 
paclitaxel/ carboplatin; and the expression of TGFß1, TßRI, and TßRII mRNA was evaluated. The 
authors found that a lower TGFß1 mRNA expression was associated with high sensitivity to 
paclitaxel and carboplatin [23]. In consistent with this report, studies on mice model have shown 
that increased TGF-β signaling could play an important role for paclitaxel-resistance and breast 
cancer recurrence [24].   
To test the role of TGFβ in UCS, researchers at the University of Oklahoma led by Dr. 
Bhattachraya utilized patient tumor samples to demonstrate that the components of the TGFβ 
pathway are expressed and functional in UCS[25, 26]. mRNA levels of TGFβ-I, TGFβ-II, TGFβR-
I and TGFβR-II were shown to be higher in recurrent compared to the non-recurrent UCS patient 
samples. 
Additionally, TGFβ induced significant phosphorylation of i) Smad 2/3 and ii) c-Jun N-terminal 
kinase (JNK), iiii) nuclear localization of nuclear factor of activated T cells 1 (NFAT1) and iv) 
cMyc transcription in UCS. While TGFβ induced proliferation through NFAT1/cMyc, regulation 
of migration/invasion and EMT are currently being explored. However the TGFβ receptor 1 
inhibitor (TGFβ R-1/ galunisertib.), efficiently blocks TGFβ induced proliferation, migration and 
EMT in UCS[15] . 
Galunisertib is a small molecule selective inhibitor of the TGFβR-I kinase domain. It has been 
evaluated in phase I testing and 300 mg/day, 14 days on/14days off was the suggested as the phase 
II dose [27, 28]. A randomized phase II study comparing 160 mg vs 300 mg/day in hepatocellular 
carcinoma patients demonstrated manageable toxicity, evidence for biomarker response, and 
Pk/PD data supporting the 300 mg/day dosing in future studies [29]. Furthermore, pre-clinical 
studies in mice model showed that galunisertib could prevent drug resistant to paclitaxel and 


Version 8.0 (22-Apr-2021) 
10 
 
enhance chemotherapy effect for mouse xenografts of human breast cancer[24]. A phase Ib study 
with gemcitabine found no dose limiting toxicity, and the 300 mg/day dose was advanced into a 
phase II study in metastatic pancreatic cancer patients [29]. A phase II study of galunisertib plus 
lomustine, galunisertib monotherapy, or placebo plus lomustine found that combination with 
lomustine did not change the PKs of galunisertib [30]. Furthermore, patients treated with 
galunisertib (150-mg, PO, twice a day) alone had less frequency of drug-related grade 3/4 adverse 
events compared with lomustine-treated patients (10% vs 26%); and galunisertib did not increase 
the frequency of lomustine related adverse events [30].  
To date, the safety and anti-cancer effect of Galunisertib combined with paclitaxel/carboplatin 
regimen remains unclear. Based on the association of TGFβ signaling with EMT in UCS, we 
propose a Phase IB feasibility trial with this novel TGFβ inhibitor in combination with carboplatin/ 
paclitaxel (CT) in CS patients. In a phase II study evaluating CT in this population, 58% of patients 
were able to complete 6 or more cycles of CT therapy [7].  We anticipate that given the excellent 
tolerability of galunisertib in previous studies, and in the potential for improved disease control 
with this agent that 60% or more of patients will receive 4 cycles of therapy.  The trial would lend 
support for a randomized phase II trial of CT +/- galunisertib.

An original, informed consent form, indicating prior approval by the institution’s Human Rights 
or Clinical Trials Committee for participation in this study, must be forwarded to the SCC CTO 
Office.  
6.1 
Treatment Plan 
6.1.1 Paclitaxel/Carboplatin plus Galunisertib 
• Paclitaxel** 175* mg/m2 over 3 hours, IV day 1 
• Carboplatin AUC 6* over 1 hour, IV day 1 (If no prior radiation therapy) 
• Galunisertib 150mg po BID day 4-17 (see section 6.3) 
• Cycles are 28 days 
* Or, in patients with history of prior pelvic radiation, Paclitaxel 135mg/m2 over 3 hours, IV day 
1; Carboplatin AUC 5* over 1 hour, IV day 1 (if no prior radiation therapy); Galunisertib 150mg 
po BID day 4-17 (see section 6.3). Cycles are 28 days.  
** Docetaxel starting at 75 mg/m2, IV day 1 may be substituted if a patient is intolerant or has an 
allergic reaction to paclitaxel.    
Patients will receive paclitaxel/carboplatin/galunisertib until unacceptable toxicity or progression.  
In the event of a complete clinical response or partial response for which the treating physician 
believes cytotoxic chemotherapy with paclitaxel/carboplatin may be safety suspended, patients 
will continue galunisertib 150mg po BID as maintenance monotherapy until progression or 
toxicity. 
6.2 
Method of Paclitaxel/Carboplatin Chemotherapy Administration 
6.2.1 Pre-medications for Paclitaxel 
Due to the risk of hypersensitivity reactions with paclitaxel, all patients should be pre-medicated 
with:  
AGENT 
DOSE/ROUTE 
DURATION 
Dexamethasone 
20 mg PO 
OR 
12 mg IV 
-12 and 6 hours prior to paclitaxel 
-30 minutes prior to paclitaxel 
 
Diphenhydramine 
50 mg IV 
30 minutes prior to paclitaxel 
Ranitidine 
Or  
equivalent alterative 
50 mg IV 
30 minutes prior to paclitaxel 
6.2.2 Antiemetics 
It is anticipated that nausea and vomiting may be a significant side effect. Based on an updated 
ASCO antiemetic guidelines, adult patients who are treated with carboplatin at AUC ≥ 4 should 
be offered a three-drug combination of an NK1 receptor antagonist (like fosaprepitant), a 5-HT3 
receptor antagonist, and dexamethasone[31]. Patients should receive fosaprepitant and either 
ondansetron, granisetron, or dolasetron prior to chemotherapy plus dexamethasone (10-20 mg IV). 


Version 8.0 (22-Apr-2021) 
17 
 
For some patients the addition of lorazepam (1-2 mg IV 30 minutes prior to chemotherapy) may 
also be appropriate.  
Note: Due to potential fosaprepitant drug interactions with oral dexamethasone[32], dose 
adjustment of dexamethasone should be considered.  
6.2.3 BSA Calculation 
If the body surface area is > 2.0m2 then drugs should be dosed at 2.0 m2.  
6.2.4 Post pre-medication 
After premedication, paclitaxel will be given at a dose of 175 mg/m2 as a 3-hour infusion or 
135mg/m2 as a 3-hour infusion for those patients with prior pelvic radiotherapy 
6.2.5 Paclitaxel/Carboplatin dose 
Carboplatin dosed to an AUC of 5 for patients receiving docetaxel rather than paclitaxel or with 
prior pelvic radiation; or AUC 6 for patients with prior radiation will be given IV over 30 minutes 
after paclitaxel.  
The dose of carboplatin will be calculated by the formula of Calvert et al. 
CALVERT FORMULA: 
Carboplatin dose (mg) = (Target AUC) X (GFR + 25) 
For the purposes of this protocol, GFR will be estimated based on the calculated creatinine 
clearance (Cockroft-Gault equation).  
Dosing of paclitaxel in patients with hepatic impairment is discussed in section 7.5.4 
The dose of carboplatin must be recalculated for each cycle if patient has weight change of greater 
than or equal to 10% from baseline. 
6.2.6 Regimen 
This regimen can be administered in an outpatient setting. 
Regimen will be repeated every 28 days until unacceptable toxicity or progression.  In the event 
of a complete clinical response or partial response for which the treating physician believes 
cytotoxic chemotherapy with paclitaxel/carboplatin may be safely discontinued, 4 cycles of 
combination therapy is recommended; treatment may be changed to monotherapy with galunisertib 
monotherapy with 28 day cycles with galunisertib alone on days 4-17. 
Recommended guidelines for dose reductions/discontinuation are described in section 7. 
6.3 
Administration of Galunisertib 
Studies must be conducted in accordance with ICH guidelines and protocols must be developed 
following section 6 of the ICH guidelines.  
6.3.1 Administration 
Galunisertib will be administered orally 150mg, bid, 14 days on and 11days off starting on day 4 
and ending on 17 of a 28 day cycle.   
A cycle (28 days) will be defined as an intermittent dosing regimen of 14 days of galunisertib 
followed by 11 days without galunisertib administration. Any missed doses should not be made 
up. No patient should receive more than 14 consecutive days of galunisertib dosing for safety 
reasons.  


Version 8.0 (22-Apr-2021) 
18 
 
To date, galunisertib at the IB defined dose is well tolerated in patients. If a toxicity is observed 
that may be related to galunisertib, a dose reduction to 80 mg BID is permitted.   
6.3.2 Recommended Guidelines for Dose Reductions/Discontinuation are as Follows: 
If a patient experiences any of the following events that are considered possibly related to 
galunisertib, galunisertib will be omitted until the event resolves:  
• Neutropenia with absolute neutrophil count (ANC) <0.5 x 109/L x 7 days, or ANC <1.0 x 
109/L with a single temperature of >101oF/38.3oC or a sustained temperature of 
>100.4oF/38oC for more than 1 hour, or thrombocytopenia with platelet count <50,000 x 
109/L  
• Hematologic toxicity must resolve to baseline or </= grade 1 prior to resumption of 
galunisertib therapy.  
• Non-hematologic toxicity must resolve to CTCAE Grade≤1 or baseline (with the exception 
of alopecia, fatigue, skin rash, nausea, vomiting, constipation, or diarrhea that can be 
controlled with treatment).  
6.3.3 Dose reduction 
If dosing is delayed for treatment-related AEs for more than 2 weeks, and the patient recovers 
within 28days, the patient may continue at a reduced dose of 80 mg BID (160-mg total daily dose). 
If recovery is >28 days, the patient must be withdrawn from study treatment. No patient will have 
his/her dose reduced more than once. Dose re-escalation to the previous dose is not permitted. 
7 TREATMENT MODIFICATIONS 
Dose modification is based on history of prior pelvic radiation therapy, interim nadir levels, and 
delays due to pre-treatment counts. No dose escalation will be permitted. Toxicity will be 
classified based on the current Common Toxicity Adverse Events (CTCAE) version 4.0

A third occurrence of grade 3 thrombocytopenia with bleeding or grade 4 thrombocytopenia will 
necessitate discontinuation of carboplatin chemotherapy.  Discussion regarding continuation of 
paclitaxel + galunisertib or galunisertib alone will be one a case by case basis with the study PI. 
No reduction below lowest dose level specified is allowed. If grade 4 neutropenia or 
thrombocytopenia is observed at the lowest dose levels, the Study Chair should be contacted and 
the patient will discontinue the study treatment. 
Dosing of galunisertib should be held until hematologic parameters are within range for treatment. 
If dosing is delayed for treatment-related AEs for more than 2 weeks, and the patient recovers 
within 28 days, the patient may continue at a reduced dose of 80 mg BID (160-mg total daily dose). 
If recovery is >28 days, the patient must be withdrawn from study treatment. No patient will have 
his/her dose reduced more than once. Dose re-escalation to the previous dose is not permitted. 
7.4.2 Pre-cycle Initiation Counts 
No subsequent course of therapy should be given until the ANC > 1500/mcl and the PLT count > 
75,000/mcl. If dose is held due to pre-treatment myelosuppression, recheck counts weekly. If 
therapy is delayed 3 weeks or longer from scheduled administration, the Study Chair should be 
notified and the patient should be removed from study treatment. 
7.5 
Dose Modifications-Non-Hematologic Toxicity 
7.5.1 Neurologic 
Neurotoxicity (paresthesia, neuropathy, toxicity)- as detected on pre-cycle initiation evaluation. 
Grade 0-1- No change, Grade 2- Hold paclitaxel until neuropathy improves to ≤ grade 1 level, then 
reduce paclitaxel by one dose level. Grade 3-4 requires removal of patient from study treatment. 


Version 8.0 (22-Apr-2021) 
22 
 
7.5.2 Gastrointestinal  
Nausea/vomiting: Increased antiemetic therapy, outpatient IV hydration, and hospital admission 
should be attempted prior to dose reduction.  
As reported greater than 48 hours following completion of chemotherapy cycle:  
Grade 0-3 toxicity- No change, Grade 4- reduce all drugs one dose level. 
Other toxicity: For any Grade 3-4 toxicity not mentioned above, protocol treatment should be 
withheld until patient recovers to ≤ Grade 1 status. Subsequent courses of therapy should be given 
with a one level dose reduction of agent(s) felt to be responsible. In general, unusual toxicities 
should be discussed with the Study Chair. 
If therapy is delayed 4 weeks or longer from scheduled administration, the Study Chair should be 
notified and the patient should be removed from study. 
7.5.3 Cardiac 
Given the cardiovascular toxicities that were observed in preclinical studies, monitoring must be 
performed as per the guidance below which is accordance with feedback obtained from the FDA. 
The specific cardiotoxicities seen in these preclinical studies were vascular degeneration and 
hemorrhage, resulting in development of valvular insufficiency and aneurysmal type changes in 
the large vessels at the base of the aorta or thoracic aorta. These changes occurred when treatment 
was administered continuously and at higher doses than used in humans.  If moderate or severe 
heart valve insufficiency or new aneurysms are observed, the patient must immediately be 
discontinued from the treatment and the adverse event reported to Lilly within 24 hours (SAE). 
General Guidance for Cardiotoxicity monitoring  
Prior to Enrollment 
•  MRI or CT scan (with contrast) of chest will be locally assessed for enrollment and safety 
decisions by a physician or a person who is qualified by experience or training. The 
objective of this evaluation is to assess for possible aneurysms of the ascending aorta and 
aortic arch. Should the patient have a previous history of abdominal aneurysm, an 
additional abdominal MRI or CT is required. NOTE: If a chest MRI or CT scan (with 
contrast) is performed as part of standard screening and on-treatment tumor assessment, 
this same scan may be used for safety evaluation, provided that it properly assesses the 
great vessels of the heart.  
During Study 
•  CT with contrast or MRI will be conducted at 6 cycles and then as clinically indicated. 
30-days follow-up visit 
• MRI or CT scan with contrast of chest to assess the large vessels of the heart: Perform if 
there was no previous post-treatment scan, if findings were observed on a previous scan, 
or if clinically indicated. 
7.5.4 Hepatic Function 
Dose adjustment of paclitaxel in patients with hepatic impairment include: 
3-hour infusion:  
• Transaminases <10 times ULN and bilirubin level ≤1.25 times ULN: 175 mg/m2 
• Transaminases <10 times ULN and bilirubin level 1.26 to 2 times ULN: 135 mg/m2 


Version 8.0 (22-Apr-2021) 
23 
 
• Transaminases <10 times ULN and bilirubin level 2.01 to 5 times ULN: 90 mg/m2 
• Transaminases ≥10 times ULN or bilirubin level >5 times ULN: Avoid use

4 The patient will be followed up every 3 month with phone check in after the last visit for 
duration of 2 years from date of registration. 
5 Each patient must have available tissue sample (include RNA, snap frozen and FFPE tissue) 
prior to treatment. For patients with a primary diagnosis, use of archival tissue from surgery 
or a new biopsy is acceptable. For patients with recurrence or progression, a new biopsy is 
required prior to receiving treatment. For patients with measurable disease, a second biopsy 
will be collected after cycle 1. 
6 During the COVID-19 crisis, protocol mandated visits may be performed via telemedicine or 
visits may be combined in order to prevent imminent safety risks to patients. Weekly 
laboratory visits during combination treatment with Paclitaxel/Carboplatin/Galunisertib are 
allowed to change to every 28 days. All such changes to the visit schedule must be clearly 
documented in the subject’s chart. Changes in study visit schedules or missed visits must be 
explained in the final clinical study report. 
8.2 
Pharmacokinetics 
For the first 6 subjects only, blood will be collected for PK testing of galunisertib levels on 
• Cycle 1 day 4 
o pre-dose (within 30 minutes of dose delivery time) 
• Cycle 1 day 8  
o pre-dose 
o Cycle 2 day 1 
o pre-dose 
Approximately 4ml of venous blood samples will be drawn into sodium heparinized tubes at each 
time-point for measurement of LY2157299. Plasma samples will be used to assay for LY2157299 
using a validated liquid chromatography-mass spectrometry (LC/MS) method [28, 33]. 
8.3 
Tissue Biopsy for Pharmacodynamics 
• Each patient must have available tissue sample (include RNA, snap frozen and FFPE 
tissue) prior to treatment. 
• For patients with a primary diagnosis, use of archival tissue from surgery or a new biopsy 
is acceptable.  
• For patients with recurrence or progression, a new biopsy is required prior to receiving 
treatment. 
• For patients with measurable disease, a second biopsy will be collected after cycle 1 
Please see lab manual for more detailed information of sample collection and shipping. 
9 EVALUATION CRITERIA   
9.1 
Parameters of Outcome–RECIST 1.1 Criteria  
9.1.1 Measurable Disease Definition 
Measurable disease is defined as at least one lesion that can be accurately measured in at least one 
dimension (longest dimension to be recorded). Each lesion must be ≥ 10 mm when measured by 
CT and MRI; or ≥ 20 mm when measured by conventional techniques, including plain x-ray.  
9.1.2 Baseline Documentation of “Target” and “Non-Target” lesions 
All measurable lesions up to a maximum of 5 lesions per organ and 10 lesions in total 
representative of all involved organs should be identified as target lesions and will be recorded and 


Version 8.0 (22-Apr-2021) 
25 
 
measured at baseline. Target lesions should be selected on the basis of their size (lesions with the 
longest dimension) and their suitability for accurate repetitive measurements by one consistent 
method of assessment (either by imaging techniques or clinically). A sum of the longest dimension 
(LD) for all target lesions will be calculated and reported as the baseline sum LD. The baseline 
sum LD will be used as reference to further characterize the progression of the measurable 
dimension of the disease. Tumor within a previously irradiated field will be designated as “non-
target” lesions unless progression is documented or a biopsy is obtained to confirm persistence at 
least 90 days following completion of radiation therapy.  
All other lesions (or sites of disease) should be identified as non-target lesions and should also be 
recorded at baseline. Measurements are not required and each of these lesions should be followed 
as stable (the persistence of a non-target lesion), complete response (the disappearance of a non-
target lesion) or progressive disease (the unequivocal progression of a non-target lesion).  
All baseline evaluations of disease status should be performed as close as possible to the start of 
treatment and never more than 4 weeks before the beginning of treatment.  
Measurement of the longest dimension of each target lesion size is required for follow-up. Change 
in the sum of these dimensions affords some estimate of change in tumor size and hence therapeutic 
efficacy. All disease must be assessed using the same technique as baseline.  
9.1.3 Definition of Disease Progression  
Progression for patients with measurable disease at baseline is defined as ANY of the following: 
• At least a 20% increase in the sum of LD target lesions taking as reference the smallest 
sum LD recorded since study entry; in addition to the relative increase of 20%, the sum 
must also demonstrate an absolute increase of at least 5 mm 
• In the case where the ONLY target lesion is a solitary pelvic mass measured by physical 
exam which is not radiographically measurable, a 50% increase in the LD is required taking 
as reference the smallest LD recorded since study entry  
• The appearance of one or more new lesions  
• Death due to disease without prior objective documentation of progression  
• Global deterioration in health status attributable to the disease requiring a change in therapy 
without objective evidence of progression  
• Unequivocal progression of existing non-target lesions, other than pleural effusions 
without cytological proof of neoplastic origin, in the opinion of the treating physician (in 
this circumstance an explanation must be provided)  
Progression for patients with non-measurable disease at baseline is defined as increasing clinical, 
radiological, or histological evidence of disease since study entry.  
9.1.4 Survival 
Survival is the observed length of life from the date of study entry to death or the date of last 
contact.  
9.1.5 Progression Free Survival 
Progression free survival is the period from the date of study entry until disease progression, death, 
or date of last contact.  


Version 8.0 (22-Apr-2021) 
26 
 
9.2 
Subjective Parameters 
The performance status, specific symptoms, and side effects are graded according to the CTCAE. 
Of particular interest will be ≥grade 3 adverse events. 
9.3 
Definition of Evaluable Patients 
Evaluable patients will be defined as patients who receive at least four cycle of study treatment. 
Patients who withdraw consent before completion of four cycles will be replaced. 
10 DURATION OF STUDY  
Treatment may continue as long as the patient is receiving clinical benefit and not experiencing 
excessive toxicity or disease progression.  If a complete clinical response is achieved or for patients 
who come on study with no measurable disease (e.g. post operative early stage) or achieve a 
durable partial response for which the treating physician feels discontinuation of cytotoxic 
chemotherapy is an option, 4 cycles of combination therapy is recommended with an option for 
maintenance therapy with galunisertib monotherapy until toxicity, progression.   
Follow-up is required as outlined in Section 8.1 In brief, patients will be seen every 28 days (prior 
to each cycle of therapy) while receiving active chemotherapy and/or galunisertib maintenance.  
CT scans to assess response will be performed prior to every odd cycle.  Patients will also be seen 
30 days after last study medication is issued. Required study procedures are based on the presence 
or absence of galunisertib related cardiac or other toxicities and are outlined in the footnotes of 
section 7. Additionally, birth control must continue for 6 months after discontinuation of 
galunisertib. After the last visit, the patient will be followed up with phone check in every 3 month 
for duration of 2 years from date of registration. 
A patient is considered off study therapy when the patient has progressed or died prior to 
completion of study therapy, a non-protocol drug or therapy (directed at the disease) is initiated or 
all study therapy is totally discontinued. Survival and progression data will continue to be 
collected.  
11 STUDY MONITORING AND REPORTING PROCEDURES   
In the event of an adverse event the first concern will be for the safety of the subject. Investigators 
are required to report to Lilly Drug Safety ANY serious treatment emergent adverse event 
(STEAE) as soon as possible.   
A STEAE is any sign, symptom or medical condition that emerges during treatment or during a 
post-treatment follow-up period that (1) was not present at the start of treatment and it is not a 
chronic condition that is part of the patient’s medical history, OR (2) was present at the start of 
treatment or as part of the patient’s medical history but worsened in severity and/or frequency 
during therapy, AND that meets any of the following regulatory serious criteria: 
• Results in death  
• Is life-threatening  
• Requires or prolongs inpatient hospitalization  
• Is disabling  
• Is a congenital anomaly/birth defect  


Version 8.0 (22-Apr-2021) 
27 
 
• Is medically significant or requires medical or surgical intervention to prevent one of the 
outcomes listed above. 
11.1 Reporting of Serious Treatment Emergent Adverse Events  
All STEAEs should be recorded on a Form and emailed or faxed to the Sponsor: 
Email: SCCIITreporting@ouhsc.edu 
Or 
Fax: 1-405-271-1416. 
AND 
Eli Lilly and Company 
Local Safety Representative 
Fax: 
866-644-1697 
(Please use the safety reporting fax cover sheet attached to this document for your fax 
transmission) 
Adverse Event Reporting Period 
The study period during which all AEs and SAEs must be reported begins after informed consent 
is obtained and initiation of study treatment and ends 30 days following the last administration of 
study treatment or study discontinuation/termination, whichever is earlier.  After this period, 
investigators should only report SAEs that are attributed to prior study treatment.  
The principal investigator is responsible for ensuring that all AEs and SAEs that are observed or 
reported during the study, are collected and reported to the FDA, appropriate IRB(s) and sponsor 
institute in accordance with CFR 312.32 (IND Safety Reports).  
All reportable events should be sent to the Sponsor via email/fax: 
Email: SCCIITreporting@ouhsc.edu 
Or 
Fax: 1-405-271-1416. 
In addition, the sponsor institute/principal investigator is responsible for notifying Eli Lilly and 
Company for AE/SAE related to Galunisertib in parallel of such events within 24 hours of the 
Sponsor/PI becoming aware of the event. The following reportable events must be submitted to 
Eli Lilly and Company 
• Serious Adverse Events 
• Exposure during Pregnancy or Breastfeeding (even if not associated with an adverse event) 
11.2 MedWatch 3500a Reporting Guidelines 
In addition to completing appropriate patient demographic and suspect medication information, 
the report should include the following information within the Event Description (section 5) of the 
MedWatch 3500a form: 
• Treatment regimen (dosing frequency, combination therapy) 
• Protocol description (and number, if assigned) 


Version 8.0 (22-Apr-2021) 
28 
 
• Description of event, severity, treatment, and outcome, if known 
• Supportive laboratory results and diagnostics 
• Investigator’s assessment of the relationship of the adverse event to each investigational 
product and suspect medication 
Follow-up information: 
Additional information may be added to a previously submitted report by any of the following 
methods: 
• Adding to the original MedWatch 3500a report and submitting it as follow-up 
• Adding supplemental summary information and submitting it as follow-up with the 
original MedWatch 3500a form  
• Summarizing new information and faxing it with a cover letter including subject identifiers 
(i.e. D.O.B. initial, subject number), protocol description and number, if assigned, suspect 
drug, brief adverse event description, and notation that additional or follow-up information 
is being submitted  (The subject identifiers are important so that the new information is 
added to the correct initial report) 
Occasionally Lilly may contact the reporter for additional information, clarification, or current 
status of the subject for whom and adverse event was reported.  
11.3 Assessing Causality 
Investigators are required to assess whether there is a reasonable possibility that galunisertib 
combined treatment caused or contributed to an adverse event.  The following general guidance 
may be used. 
Yes: 
if the temporal relationship of the clinical event to galunisertib administration makes a 
causal relationship possible, and other drugs, therapeutic interventions or underlying 
conditions do not provide a sufficient explanation for the observed event. 
No: 
if the temporal relationship of the clinical event to galunisertib administration makes a 
causal relationship unlikely, or other drugs, therapeutic interventions or underlying 
conditions provide a sufficient explanation for the observed event. 
11.4 SAFETY REPRORTING REQUIREMENTS FOR IND HOLDERS 
In accordance with 21 CFR 212.32, sponsors of studies conducted under an IND must comply with 
following safety reporting requirements:  
a. Expedited IND Safety Reports: 
7 Calendar-Day Telephone or Fax Report: 
The Sponsor is required to notify the FDA of any fatal or life-threatening adverse event that is 
unexpected and assessed by the investigator to be possibly related to the use of galunisertib.  An 
unexpected adverse event is one that is not already described in the Investigator Brochure.  Such 
reports are to be telephoned or faxed to the FDA and Lilly within 7 calendar days of first learning 
of the event.  Each telephone call or fax transmission (see fax number below) should be directed 
to the FDA new drug review division in the Center for Drug Evaluation and Research or in the 
product review division for the Center for Biologics Evaluation and Research, whichever is 
responsible for the review of the IND. 


Version 8.0 (22-Apr-2021) 
29 
 
15 Calendar-Day Written Report:   
The Sponsor is also required to notify the FDA and all participating investigators, in a written IND 
Safety Report, of any serious, unexpected AE that is considered possibly related to the use of 
galunisertib.  An unexpected adverse event is one that is not already described in the Investigator 
Brochure. 
Written IND Safety Reports should include an Analysis of Similar Events in accordance with 
regulation 21 CFR § 312.32.  All safety reports previously filed with the IND concerning similar 
events should be analyzed.  The new report should contain comments on the significance of the 
new event in light of the previous, similar reports.   
Written IND safety reports with Analysis of Similar Events are to be submitted to the FDA, Lilly 
Drug Safety, and all participating investigators within 15 calendar days of first learning of the 
event.  The FDA prefers these reports on a MedWatch 3500a Form but alternative formats are 
acceptable (e.g. summary letter). 
A log of the IND safety reports will be submitted annually to the OUHSC IRB at the time of 
Continuing Review.  
b. IND Annual Reports 
In accordance with the regulation 21 CFR § 312.32, the Sponsor shall within 60 days of the 
anniversary date that the IND went into effect submit a brief report of the progress of the 
investigation.  Please refer to Code of Federal Regulations, 21 CFR § 312.32 for a list of the 
elements required for the annual report.  
11.5 Collection and Recording Adverse Events 
All adverse events (AEs) of any grade will be collected, identified using the MedDRA 
terminology, graded as to severity, assessed for causality, and followed until resolution. 
All AEs, regardless of the source of identification (eg, physical examination, laboratory 
assessment, ECG, reported by patient), must be documented in the eCRF and reported in the IND 
annual report. 
All AEs will be collected and recorded in the eCRF for each patient from the first day of dosing 
until 30 days after the last dose of study treatment. All AEs and SAEs experienced by a patient, 
irrespective of the suspected causality, will be monitored until the AE or SAE has resolved, any 
abnormal laboratory values have returned to baseline or normal levels, until there is a satisfactory 
explanation for the changes observed, until the patient is lost to follow-up, or until the patient has 
died. 
11.5.1 Definitions 
Adverse event: An adverse event is any untoward medical occurrence that occurs in a patient or 
clinical investigation subject administered a pharmaceutical product, and which does not 
necessarily have to have a causal relationship with this treatment. An AE can therefore be any 
unfavorable and unintended sign (including clinically significant abnormal laboratory findings), 
symptom, or disease temporally associated with the use of an investigational product, whether or 
not considered related to the product. 


Version 8.0 (22-Apr-2021) 
30 
 
Adverse events may include the onset of new illness and the exacerbation of pre-existing medical 
conditions. An AE can include an undesirable medical condition occurring at any time, including 
baseline or washout periods, even if no study treatment has been administered. 
Treatment-emergent:  A treatment-emergent adverse event will be defined as any new AE that 
begins, or any preexisting condition that worsens in severity, after at least 1 dose of study treatment 
has been administered. 
Serious adverse event: A serious adverse event is defined as any untoward medical occurrence 
that, at any dose: 
• Results in death 
• Is life-threatening 
o Note: This means that the patient is at immediate risk of death at the time of the event; 
it does not mean that the event hypothetically might have caused death if it were more 
severe 
• Requires inpatient hospitalization or prolongation of existing hospitalization 
o Any AE that prolongs hospitalization will be considered an SAE. 
o Exception: Planned hospitalization (eg, for observation, protocol compliance, elective 
procedures, social reasons, etc.) will not be considered an SAE; however, the reason 
for the planned hospitalization should be captured in medical history. 
• Results in persistent or significant disability or incapacity 
• Is a congenital anomaly or birth defect 
• Is an important medical event(s) 
o An important medical event may not be immediately life-threatening or result in death 
or hospitalization but may jeopardize the patient or require intervention to prevent one 
of the above outcomes.  
11.5.2 Assessment of Adverse Events 
Each AE will be assessed by the Investigator with regard to intensity and causality with regard to 
study treatment as outlined in the following sections. 
Intensity 
Investigators should assess the severity of AEs according to CTCAE. In general, CTCAE (Version 
4) severity grades are: 
Grade 1:  
Mild; asymptomatic or mild symptoms; clinical or diagnostic observations only;        
intervention not indicated 
Grade 2:  
Moderate; minimal, local or noninvasive intervention indicated; limiting 
ageappropriate instrumental activities of daily living (ADL). (Instrumental ADL 
refer to preparing meals, shopping for groceries or clothes, using the telephone, 
managing money, etc.) 
Grade 3:  
Severe or medically significant but not immediately life-threatening; 
hospitalization or prolongation of hospitalization indicated; disabling; limiting self-
care ADL. (Self-care ADL refer to bathing, dressing and undressing, feeding self, 
using the toilet, taking medications, and not bedridden.) 
Grade 4:  
Life-threatening consequences; urgent intervention indicated 
Grade 5:  
Death related to AE 


Version 8.0 (22-Apr-2021) 
31 
 
A distinction should be made between serious and severe AEs. Severity is a measure of intensity 
whereas seriousness is defined by the criteria above in Section 7.4 and 7.5. For example, a mild 
degree of gastrointestinal bleeding requiring an overnight hospitalization for monitoring purposes 
may be considered an SAE but is not necessarily severe. Similarly, an AE that is severe in intensity 
is not necessarily an SAE. For example, alopecia may be assessed as severe in intensity but may 
not be considered an SAE. 
Causality 
The Investigator will assess the causality/relationship between the study drug and the AE. One of 
the following categories should be selected based on medical judgment, considering the definitions 
and all contributing factors: 
• Related: A clinical event, including laboratory test abnormality, occurs in a plausible time 
relationship to treatment administration, and which concurrent disease or other drugs or 
chemicals cannot explain. The response to withdrawal of the treatment should be clinically 
plausible. 
• Possibly related: A clinical event, including laboratory test abnormality, with a reasonable 
time sequence to administration of the treatment, unlikely to be attributed to concurrent 
disease or other drugs or chemicals. 
• Unlikely related: A clinical event, including laboratory test abnormality, with a temporal 
relationship to treatment administration which makes a causal relationship improbable, or 
in which other drugs, chemicals or underlying disease provide likely explanations. 
• Unrelated: A clinical event, including laboratory test abnormality, with little or no 
temporal relationship with treatment administration. Typically explained by extraneous 
factors (eg, concomitant disease, environmental factors, or other drugs or chemicals). 
12 STATISTICAL CONSIDERATIONS 
12.1 Data Analysis Plan 
(a) Definition of primary outcome/endpoint: 
1) Completion of 4 cycles- completion of a cycle will be defined as receiving both 
carboplatin/paclitaxel and taking ≥75% of the doses of GB for the cycle  
(b) Definition of secondary outcomes/endpoints: 
1) Adverse event occurrence and grade, as assessed by the CTCAE v4. 
2) PFS- duration of time from enrollment to RECIST progression or death from any cause, 
censored at last disease assessment or loss to follow-up; and OS – duration of time from 
enrollment to death from any cause, censored at date last known alive or loss to follow-
up 
3) Galunisertib serum concentrations levels on day 4, 8 and 29 (cycle 2 day 1) 
(c) Exploratory: 
Correlate mRNA levels of EMT markers (SNAI1, N-Cad) and TGFβ-I, TGFβR-I and 
TGFβR-II with response rate (complete response + partial response) and clinical benefit 
ratio (response rate + stable disease at 6 months) 
(d) Sample size and Analytic plan for primary objective: 


Version 8.0 (22-Apr-2021) 
32 
 
The % of patients completing 4 cycles will be calculated and a 90% confidence interval 
constructed for the completion rate. With 25 patients and an expected completion rate of 
60%, the lower bound of the two-sided exact Clopper-Pearson 90% confidence interval 
(CI) would be 42%, which provides sufficient evidence that the combined regimen is 
feasible for inclusion in a randomized Phase II study. The following table provides 90% 
confidence intervals when the expected completion rate ranges from 60% to 80%, with a 
sample size of 25. Patients who come off the treatment for disease progression but did not 
experience toxicity requiring termination of treatment will be included among those 
patients completing the target goal of treatment of 4 cycles. Assuming 30% of the enrolled 
patients will drop out, we will enroll 36 patients to reach the targeted sample size (n = 25).

63% - 92% 
 
(e) Analytic plan for secondary objectives: 
1) To determine the frequency and severity of adverse events as assessed by the CTCAE 
v4. 
• Frequency and severity of adverse events will be tabulated, by body system, type 
and maximum grade. 
2) To determine the PFS and OS of patients receiving combination CT + GB. 
• Median PFS and OS (and CIs) for patients who receive the combined regimen under 
study will be computed using the Kaplan-Meier curves and compared to a historical 
cohort of patients who received the standard care. 
3) To ascertain pharmacokinetic profile of GB when given in a combination regimen with 
CT. 
• Galunisertib levels will be drawn cycle 1 day 4: pre-dose and 2 and 6 hours post 
dose; Day 8 and day 29: pre-dose for the first 6 patients 
• Levels over time will be summarized descriptively, as quartiles and range, and 
graphically using boxplots for example.  These will be compared to previous phase 
I data describing the pharmacokinetics of galunisertib to determine if it is 
significantly impacts by co-administration of carboplatin/paclitaxel. 
4) To determine if mRNA levels of TGFβ-I, TGFβ-II, TGFβR-I and TGFβR-II are 
associated with response to galunisertib therapy including galunisertib. 
• The response rate (complete response + partial response) and clinical benefit ratio 
(response rate + stable disease at 6 months) will be tabulated according to high and 
low mRNA (divided by median mRNA levels observed) concentrations of TGFβ-
I, TGFβ-II, TGFβR-I and TGFβR-II. Because of the sample size, these analyses are 
hypothesis generating and hypothesis testing will not be conducted. 


Version 8.0 (22-Apr-2021) 
33 
 
(f) Accrual 
25 patients will be enrolled over a period of 3 years. 
12.2 Interim Analysis 
If the main cohort is activated, an interim safety analysis will be conducted when 6 patients have 
received ≥ 3cycles of treatment. If a DLT occurs in 2 or more patient, the dose of GB will be 
decreased to a lower level (level -1) at 80mg, PO, BID and an additional analysis will then be 
conducted after 6 patients have completed ≥ 3cycles. DLT is defined as either hematologic or non-
hematologic toxicity (assessed in accordance with the CTCAE Version 4.0), which cause any of 
the following: 
Hematologic Toxicity: 
• Dose delay of greater than 3 weeks due to failure to recover counts. 
• Study treatment-related febrile neutropenia. 
• Grade 4 neutropenia lasting > 7 days. 
• Study treatment-related Grade 4 thrombocytopenia or bleeding associated with Grade 3 
thrombocytopenia. 
Non-Hematologic Toxicity: 
• Study treatment-related Grade 3 or Grade 4 non-hematological toxicity (excluding 
alopecia, fatigue, hypersensitivity reaction), (if controlled w/ medications exclude nausea, 
vomiting, constipation, diarrhea, hypokalemia, hypomagnesemia, hypocalcemia, 
hypophosphatemia) 
• Any drug-related death 
All AEs of the 6 patients will be listed. With 6 patients, there is high probability (>0.80) to observe 
at least one DLT, if the true DLT rate is at least 25% (Table 1). The probability of observing ≥2 
DLTs is high (≥0.77) if the true rate of DLTs is at least 40% (Table 1).

13 DATA AND SAFETY MONITORING PLAN 
Safety oversight will be performed by Stephenson Cancer Center’s (SCC) internal Data and Safety 
Monitoring Committee (DSMC). The DSMC is composed of individuals with the appropriate 
expertise in adult and pediatric hematology and medical oncology, radiation oncology, 
translational and correlative science, pharmacy, nursing and biostatistics. The DSMC operates 
under the rules of an approved data safety monitoring plan which complies with the National 
Cancer Institute (NCI) guidelines published as Essential Elements of a Data and Safety Monitoring 
Plan for Clinical Trials Funded by NCI as of January 2005 and the “NIH Policy for Data and 


Version 8.0 (22-Apr-2021) 
34 
 
Safety 
Monitoring,” 
NIH 
Guide 
for 
Grants 
and 
Contracts, 
http://grants.nih.gov/grants/guide/notice-files/not98-084.html.  
The Data Safety Monitoring Committee is charged with oversight of participant safety, study 
conduct and the validity and integrity of data for clinical trials at SCC. While the focus of the 
DSMC is to monitor interventional investigator initiated trials (IITs) that are not subject to external 
monitoring, it has the authority to monitor any SCC protocol when potential concerns are 
identified. The DSMC also has the authority to suspend or close a study until the principal 
investigator addresses any issues that may cause harm or increase risks to subjects. The DSMC 
reports all findings to the Institutional Review Board (IRB).  
Under the direction of the DSMC chair, a full board meeting is convened on a quarterly basis to 
review the accumulated safety data, accrual information, and additional information as stated in 
the DSMC plan.  
13.1 DSMC Auditing  
In addition to monitoring, the DSMC oversees an internal auditing process to ensure subject safety and 
data quality. All cancer-related clinical trials active at the SCC are eligible for audit; however, priority 
is placed on those clinical trials that are not monitored or audited by an outside entity. If an external 
entity conducts an audit of a clinical trial at the SCC, then the findings of that audit are reported to the 
DSMC, either through the formal audit report provided by the external auditing entity, if available, or 
from the PI, who will report any findings communicated during the audit process. 
14 DATA HANDLING AND RECORD KEEPING 
14.1 Data Quality Assurance 
Stephenson Cancer Center (SCC) will be responsible for clinical monitoring all data for this study.   
14.2 Electronic Case Report Forms 
The Principal Investigator will develop electronic case report forms for study data entry.  All study 
data will be stored in a HIPAA-compliant database.  Only Investigator and assigned research staff 
will have access to study data.  The electronic case report forms will be available to sponsor, IRB 
or regulatory authorities in even of an audit.   
14.3 Record Retention  
Investigator will retain all research documents and case report forms at study site.   
15 ETHICAL AND REGULATORY CONSIDERATIONS 
15.1 Ethical Conduct of the Study 
The study will be conducted in full conformance with the ICH E6 guideline for Good Clinical 
Practice and the principles of the Declaration of Helsinki in addition to the requirements of the 
ICH E2A guidelines. This study will also comply with U.S. FDA regulations under a U.S. 
Investigational New Drug (IND) application in addition to local, state, and federal laws. 


Version 8.0 (22-Apr-2021) 
35 
 
15.2 Informed Consent 
The informed consent document will be in compliance with ICH GCP, local regulatory 
requirements, and legal requirements. The informed consent document used in this study, and any 
changes made during the course of the study, will be prospectively approved by the local IRB. 
The investigator must ensure that each study patient is fully informed about the nature and 
objectives of the study and possible risks associated with participation. The investigator, or a 
person designated by the investigator, will obtain written informed consent from each patient 
before any study-specific activity is performed. The study site will retain the original of each 
patient’s signed consent document. 
15.3 Institutional Review Board or Ethics Committee 
This protocol, the Informed Consent document, any information to be given to the patient, and 
relevant supporting information must be submitted to the IRB by the Principal Investigator and 
reviewed and approved by the IRB before the study is initiated. 
The Principal Investigator is responsible for providing written summaries of the status of the study 
to the IRB annually or more frequently in accordance with the requirements, policies, and 
procedures established by the IRB. Investigators are also responsible for promptly informing the 
IRB of any protocol amendments. 
In addition to the requirements for reporting all adverse events to the Sponsor, investigators must 
comply with requirements for reporting serious adverse events to the local health authority and 
IRB. 
15.4 Confidentiality 
The Sponsor and site will maintain confidentiality standards by coding each patient enrolled in the 
study through assignment of a unique patient identification number. Patient medical information 
obtained by this study is confidential and may only be disclosed to third parties as permitted by 
the Informed Consent document (or separate authorization for use and disclosure or personal health 
information) signed by the patient, unless permitted or required by law.

a. General statistical considerations 
i. This is a single arm, phase Ib study. A total of 25 evaluable patients will be enrolled 
at the Stephenson Cancer Center.  36 patients are expected to be enrolled in the 
trial, with a 30% dropout rate.  The primary goal of this study is to determine the 
feasibility  of CT and Galunisertib as a treatment for gynecological carcinoma. 
ii. An evaluable patient is a patient who completed four cycles, defined as receiving 
both carboplatin/paclitaxel and taking >=75% of the doses of GB for the cycle.  


OU-SCC-Gunderson-Exist 
Patients who come off the treatment for disease progression but did not experience 
toxicity requiring termination of treatment will be included among those patients 
completing the target goal of treatment of 4 cycles. 
iii. Study accrual is expected to last three years. 
 
b. Sample Size and Power 
i. The primary purpose of this study is to determine the feasibility of CT and 
Galunisertib as a treatment option for patients with gynecological carcinoma.  The 
percentage of patients completing four cycles will be calculated and a 90% 
confidence interval will be constructed for the completion rate.  With 25 patients 
and an expected completion rate of 60%, the lower bound of the two-sided exact 
Clopper-Pearson 90% confidence interval (CI) would be 42%, which provides 
sufficient evidence that the combined regimen is feasible for inclusion in a 
randomized Phase II study. The following table provides 90% confidence intervals 
when the expected completion rate ranges from 60% to 80%, with a sample size of 
25. Patients who come off the treatment for disease progression but did not 
experience toxicity requiring termination of treatment will be included among those 
patients completing the target goal of treatment of 4 cycles. Assuming 30% of the 
enrolled patients will drop out, we will enroll 36 patients to reach the targeted 
sample size (n = 25).

OU-SCC-Gunderson-Exist 
 
a. Safety population: All patients who receive at least one dose of combination CT and 
Galunisertib will be included in the analyses of compliance and safety. 
b. Evaluable population: Evaluable patients will be defined as patients who complete four 
cycles of CT and take >=75% of GB for the cycle or patients who experience disease 
progression while on treatment. 
 
Patients who withdraw due to toxicity will not be included in the efficacy analysis but will be 
included in the safety analyses. 
 
6. Interim Analysis 
a. An interim dose limiting toxicity (DLT) analysis will be conducted when 6 patients have 
received ≥ 3cycles of treatment. If a DLT occurs in 2 or more patients, the dose of GB will be 
decreased to a lower level (level -1) at 80mg, PO, BID and an additional analysis will then be 
conducted after 6 patients have completed ≥ 3cycles. DLT is defined as either hematologic 
or nonhematologic toxicity (assessed in accordance with the CTCAE Version 4.0), which 
cause any of the following:  
b. Hematologic Toxicity: 
i. Dose delay greater than 3 weeks due to failure to recover counts. 
ii. Study treatment-related febrile neutropenia. 
iii. Grade 4 neutropenia lasting >7 days. 
iv. Study treatment-related Grade 4 thrombocytopenia or bleeding associated with 
Grade 3 thrombocytopenia. 
c. Non-Hematologic Toxicity 
i. Study treatment-related Grade 3 or Grade 4 non-hematological toxicity (excluding 
alopecia, fatigue, hypersensitivity reaction), (if controlled w/ medications exclude 
nausea, vomiting, constipation, diarrhea, hypokalemia, hypomagnesemia, 
hypocalcemia, hypophosphatemia). 
ii. Any drug-related death. 
d. All AEs of the 6 patients will be listed. With 6 patients, there is a high probability (>0.80) to 
observe at least one DLT, if the true DLT rate is at least 25% . The probability of observing ≥2 
DLTs is high (≥0.77) if the true rate of DLTs is at least 40%.

7. Statistical Analysis Methods 
a. The percent of patients completing 4 cycles will be calculated and a 90% confidence interval 
constructed for the completion rate. With 25 patients and an expected completion rate of 


OU-SCC-Gunderson-Exist 
60%, the lower bound of the two-sided exact Clopper-Pearson 90% confidence interval (CI) 
would be 42%, which provides sufficient evidence that the combined regimen is feasible for 
inclusion in a randomized Phase II study.  
b. Progression-Free Survival (PFS) is defined as the time in months from study entry to the date 
of death or the first documented date of progression, whichever comes first.  For patients 
who did not die and did not have progression, the PFS is censored at the last documented 
tumor assessment.  Survival curve for PFS will be generated using the Kaplan-Meier method.  
Median PFS with 95% CI will be computed. 
c. Overall survival (OS) is defined as time in months from study entry to the date of death from 
all causes. Patients who are still alive at EOS are censored on the date they were last known 
to be alive. Survival curve for OS will be generated using the Kaplan-Meier method.  Median 
OS with 95% CI will be computed. 
d. Objective response (complete response + partial response) rate will be reported with 95% CI 
using the Clopper-Pearson method.  
e. To ascertain pharmacokinetic profile of GB when given in a combination regimen with CT, 
Galunisertib levels will be drawn cycle 1 day 4: pre-dose and 2 and 6 hours post dose; Day 8 
and day 29: pre-dose for the first 6 patients.  Levels over time will be summarized 
descriptively, as quartiles and range, and graphically using boxplots for example.  These will 
be compared to previous phase I data describing the pharmacokinetics of galunisertib to 
determine if it is significantly impacted by co-administration of carboplatin/paclitaxel. 
f. Exploratory analysis will correlate mRNA levels of EMT markers (SNAI1, N-Cad) and TGFβ-I, 
TGFβR-I and TGFβR-II with response status (complete response + partial response vs. stable 
disease + progressive disease) and clinical benefit status (response rate + stable disease at 6 
months).  The response rate and clinical benefit ratio will be tabulated according to high and 
low mRNA (divided by median mRNA levels observed) concentrations of TGFβI, TGFβ-II, 
TGFβR-I and TGFβR-II. H Score of psamd2/3 staining in pretreated and post-treated patient 
tumor samples will be summarized and then correlate with the patient therapy response 
status.  Because of the sample size, these analyses are hypothesis generating and hypothesis 
testing will not be conducted.  
8. Safety Analyses 
a. Adverse Events 
i. Severity of AEs will be graded according to the CTCAE Version 4.0. 
ii. Frequency and severity of adverse events will be tabulated by body system, type 
and maximum grade. Serious adverse events will be listed. 
9. Handling of Missing Data 
Every effort will be made to collect information at all defined visits including at early withdrawal or 
dropout. Reasons for missing data will be summarized. However, there will be no imputation of 
missing data.
