Sponsor: National Cancer Institute (NCI)
Start date: 2015-01-20; Completion date: 2021-08-27
Enrollment: 111 participants; Allocation: NA; Intervention model: SINGLE_GROUP

Brief summary:
Background:

* All cells go through cycles which allow them to divide. In normal cells, checkpoint kinase 1 (Chk1) and checkpoint kinase 2 (Chk2) (CHEK 2 (Chk1/2) stop cell division at various points to allow any damage to deoxyribonucleic acid (DNA) to be repaired.
* When Chk1/2 are not present, cells stop dividing and eventually die. Chk1/2 Inhibitor (Prexasertib (LY2606368) blocks the Chk1/2 proteins.
* Researchers hope that by blocking Chk1/2, it will cause tumor cells to die, thereby shrinking tumors.

Objective:

\- To see if LY2606368 helps shrink tumors in patients with certain breast, ovarian or prostate cancers.

Eligibility:

\- Participants at least 18 years old with breast or ovarian cancer. They must have a mutation in BRCA1 BReast CAncer gene 1 and BRCA2 BReast CAncer gene 2 (BRCA1/2) genes for group 1, high grade serious ovarian cancer without BRCA1/2 mutation for group 2, or triple negative breast cancer without BRCA1/2 mutation for group 3, or prostate cancer with or without BRCA1/2 mutation for group 4.

Design:

* Participants will be screened with a medical history and physical exam. They will have blood tests, an electrocardiogram (ECG) heart test, scans, and X-rays. They will have a piece of their tumor removed at entry (computed tomography (CT)-assisted biopsy).
* Study Day 1: Participants will have a physical exam and blood drawn. They may have a CT scan of the chest, abdomen, and pelvis.
* Day 1 and Day 15 of each 28-day cycle: Participants will receive the study drug through an intravenous (IV).
* Vital signs will be checked before and after. An ECG will be done within 1 hour after.
* Day 15 and Day 28: Participants will have a physical exam, blood drawn, and a 12 lead ECG.
* Cycle 1: Participants will have weekly phone calls and blood draws. Participants may have another CT-assisted biopsy at the end of cycle 1.
* Cycle 2 and beyond, blood will be drawn every other week for routine blood tests.
* Participants will have an after-study visit with a physical exam and blood tests. Participants may have another biopsy when they progressed on treatment. They will have scans of the chest, pelvis, and abdomen and a 12 lead ECG.

Detailed description:
Background:

* Checkpoint kinases 1 and 2 (Chk1/2) are major regulators of the cell cycle and are intimately associated with the cellular response to deoxyribonucleic acid (DNA) damage and repair. Chk1/2 also function as the primary mediators of cell cycle arrest in tumors with tumor protein P53 (p53) dysfunction, such as high-grade serous ovarian cancer (HGSOC), and triple negative breast cancer (TNBC).
* Participants with germline BRCA1 BReast CAncer gene 1 and BRCA2 BReast CAncer gene 2 (BRCA1/2) mutation have inherent defects in DNA damage repair pathways.
* Chk1/2 inhibition alone yielded DNA damage and mitotic catastrophe preclinically, even in the absence of DNA damage by external agents in tumors with underlying DNA repair dysfunction.
* The second-generation Chk1/2 inhibitor (Prexasertib (LY2606368) yielded safety and preliminary single agent activity in advanced cancer participants.
* We hypothesize that LY2606368 will result in clinical benefit in participants with Germline BRCA-Mutated (gBRCAm)-associated breast or ovarian cancers, and HGSOC and TNBC with low genetic risk.

Objectives:

* To determine the objective response rate (Complete Response (CR)+Partial Response (PR) of single agent LY2606368 in patients with gBRCAm-associated breast or ovarian cancer, HGSOC and TNBC with low genetic risk.
* To determine the safety and toxicity, and progression-free interval (PFI) of LY2606368 in pretreated participants.
* To determine biochemical changes in the DNA damage repair and cell cycle check point pathways in tumor and blood samples in response to treatment.
* To determine potential resistance mechanisms to LY2606368 treatment in HGSOC.

Eligibility:

* Participants with recurrent/refractory BReast CAncer gene (BRCA) mutant breast or ovarian cancer, HGSOC, and TNBC, for whom there remains no standard curative measures.
* A documented deleterious germline or somatic BRCA mutation for breast or ovarian cancer participants enrolling in Cohort 1.
* Negative BRCA mutation testing or negative family history of hereditary breast and ovarian cancer syndrome for HGSOC (Cohort 2).
* Negative BRCA mutation testing or negative family history of hereditary breast and ovarian cancer syndrome for TNBC (Cohort 3).
* Effective with amendment I (version date 4/24/2017), Metastatic Castration-Resistant Prostate Cancer (mCRPC), Cohort 4 was closed.
* Negative BRCA mutation testing or negative family history of hereditary breast and ovarian cancer syndrome for recurrent platinum-resistant HGSOC with measurable and biopsiable disease (Cohort 5).
* Negative BRCA mutation testing or negative family history of hereditary breast and ovarian cancer syndrome for recurrent platinum-resistant HGSOC with measurable but without biopsiable disease (Cohort 6).
* Participants must be off prior chemotherapy, radiation therapy, hormonal therapy, or biological therapy for at least 4 weeks.
* Eastern Cooperative Oncology Group (ECOG) performance status 0-2 and adequate organ and marrow function.

Design:

* This is an open label, single arm phase II trial to examine activity of LY2606368 in participants in the 6 independent cohorts (Cohorts 1-6).
* LY2606368 will be dosed at the recommended phase 2 dose (RP2D) of 105 mg/m\^2 intravenous (IV) once every 14 days of a 28 day-cycle.
* Research samples including whole blood, circulating tumor cells (CTCs), and tumor biopsies will be obtained for pharmacodynamics (PD) endpoints at baseline, Cycle 1 Day 15 (6-24hour (hr) post-2nd dose), and/or at progression in all participants. Tumor biopsies will not be performed in Cohort 6.
* Participants (Cohorts 1-3, 5 and 6) will be evaluated every two cycles for response using Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 and every cycle for safety using Common Terminology Criteria for Adverse Events (CTCAE) v4.0.

Administration (FDA) to treat any type of breast or ovarian cancer, or any other type of disease.  
All cells go through cycles which allow them to divide. Cell division is important because it allows 
all living things to grow, to heal and to reproduce. In normal cells, there are many proteins which 
help to make sure that cells are dividing correctly.  LY2606368 blocks two of these proteins called 
Chk1 and Chk2.  In normal cells, Chk1/2 stop cell division at various points to allow any damage 
to DNA to be repaired and to make sure that chromosomes are lined up correctly.  When Chk1/2 
are not present, cells stop dividing and eventually die.  The researchers in this study hope that by 
blocking these proteins it will cause tumor cells to die, thereby shrinking tumors.
WHY ARE YOU BEING ASKED TO TAKE PART IN THIS STUDY?
You are being asked to participate in this study because you have been diagnosed with:
1) Breast or ovarian cancer and have a mutation in BRCA1/2 genes (BRCAm)
2) High Grade Serious Ovarian Cancer (HGSOC) OR
3) Triple Negative Breast Cancer (TNBC) OR
4) Recurrent platinum-resistant High Grade Serious Ovarian Cancer (HGSOC) AND
5) All other standard measures have failed to cure your cancer.
HOW MANY PEOPLE WILL TAKE PART IN THIS STUDY?
About 153 people will take part in this research study. 
DESCRIPTION OF RESEARCH STUDY
What will happen if you take part in this research study?  
This study consists of the following parts:

A screening period that may last up to 30 days, during which tests will be done to see if 
you qualify to take part in the study.

A treatment period consists of 28 day cycles during which you will be given study drug 
once every 14 days (day 1 and day 15 of every cycle).  This treatment period will 
continue until up to 2 cycles after your cancer goes away, until your cancer gets worse, or 
if you are withdrawn from the study.  If you cannot tolerate LY2606368, it may also be 
necessary to end your treatment.

An end of treatment visit (for safety reasons) will be done after the last dose of study 
drug.

If your cancer completely goes away, you will be followed every 4 weeks with non-
invasive imaging performed every 12 weeks until your cancer returns, gets worse, or if 
you are withdrawn from the study.

Before you begin the study
Certain standards (criteria) have been established to ensure that you are a medically appropriate 
candidate for this trial. These criteria also make sure that the results of this study can be used to 
help make decisions about treating other participants. We will record your medical history and 
give you a physical examination. We will review slides of a previous biopsy you have had to 
confirm your diagnosis. You will undergo standard blood tests including a complete blood count, 
chemistry panel, a pregnancy test, an EKG, and scans and x-rays as part of the NCI Screening 
Protocol. One test of your immune system will be a blood test that checks for the presence of the 
human immunodeficiency virus (HIV), the cause of acquired immunodeficiency syndrome 
(AIDS). HIV infection may disqualify you from this study. If you test positive for HIV, we will 
tell you what the results mean, how to find care, how to avoid infecting others, and how we report 
newly diagnosed HIV infection.
If you are eligible to participate in this trial and wish to do so, a CT-assisted biopsy of your tumor 
will be performed for research purposes before you start treatment. If you are in the one of groups 
1-3, an additional CT-assisted biopsy may be performed during Cycle 1 if you agree, after your 
dose of study drug on Day 15 and at the end of your study treatment. If you are in group 5 and 
respond to the treatment longer than 4 months, an additional CT-assisted biopsy will be performed 
when your tumor stops shrinking so that researchers can study what made the tumors stop 
responding to LY2606368. If you are in group 6, you will not have an additional CT-assited biopsy.
During the study
During the study, the study doctor and staff will monitor you for any side effects and monitor your 
cancer.  You may receive supportive care during this study.  Ask the study doctor or staff if you 
have questions about supportive care.  During Cycle 1, you will receive weekly phone calls to ask 
about whether there have been any changes to your health and about any other medications that 
you may be taking.  For safety, during Cycle 1, you will also have routine laboratory tests done 
weekly, then every other week for Cycle 2 and beyond.  About 3 tablespoons of blood will be 
drawn for these tests.  
Day 1
After all of your baseline tests are complete, you will start treatment.  On Day1, the study staff 
will perform a complete physical exam.  They will ask if there have been any changes to your 
physical health and about any medications you have taken since your screening visit.  They will 
check your vital signs and may do some routine laboratory tests.  Laboratory tests that were 
completed within the last 3 days before Cycle 1 Day 1, will not be repeated. Blood will also be 
drawn for research tests to assess certain cancer markers (about 2 tablespoons).  A CT scan of the 
chest, abdomen, and pelvis will not be repeated if you had one done within 14 days prior to the 
start of Cycle 1 Day 1.
LY260368 Therapy
You will receive the study drug LY260368 through an infusion in your vein over approximately 
one hour on Day 1 and on Day 15 of each 28-day cycle.
Therapy will be continued every 14 days until your cancer goes away, until your cancer gets worse, 
or until you are withdrawn from the study.

Your vital signs will be assessed 30 minutes before and after you have received the study drug.
An EKG will be done within 1 hour after you have received the study drug.
Day 15
On Day 15, you will be asked about whether there have any been any changes to your physical 
health and about any medications you have taken.  The study staff will perform a complete physical 
examination and you will have some routine laboratory tests done for safety.  About 3 tablespoons 
of blood will be drawn for these tests.  If you are in the one of groups 1-3, you will be asked if you 
want to have a second biopsy.  This second biopsy, which would be assisted by a CT scan, is for 
research purposes and it is optional. Even if you do not want to do this second biopsy, you can still 
continue on the study.  You will also be required to have an EKG and about 2 tablespoons of blood 
will be drawn to assess certain cancer markers. 
Day 28 
On Day 28, the first treatment cycle will end.  You will be asked about whether there have been 
any changes to your health and about any other medications you have taken.  You will have a 
complete physical exam and have about 3 tablespoons of blood drawn for routine laboratory tests. 
You will also be required to have an EKG.
Cycle 2 and beyond
Some tests will be performed every cycle, some will be performed every other cycle, some will be 
performed every three cycles, and some will be completed in the first cycle only.  If you are in the 
group 5 and on the treatment longer than 4 months, you will be asked about a second biopsy when 
your tumors start growing on imaging. This second biopsy, which would be assisted by a CT scan, 
is for research purposes and it is mandatory for the researchers to study what makes tumors become 
resistance to the treatment. This mandatory second biopsy will not be done if you (group 5) don’t 
respond to the therapy longer than 4 months. The Study Chart below gives more information about 
the timing of all of the tests needed for this study. 
When you are finished taking the drugs (treatment)
If you or your study doctor decides to stop study treatment, if your cancer has spread, or if you 
cannot tolerate the study treatment then you will be asked to return for an end of treatment visit. 
During this visit, the following will be performed:

You will have a complete physical examination to assess any changes since the last study 
visit.

Your vital signs will be measured.

You will be asked if you want to have another CT-assisted biopsy.  It will be your choice 
whether you want to have this biopsy done.

Your cancer will be evaluated through CT scans of the chest, pelvis, and abdomen. Male 
participants may also be evaluated with bone scans. Your tumor will be checked to see if 
it has grown, shrunk or stayed the same.

You will have an EKG.

* Groups 1-3: Biopsies in Cycle 1 Day 15 and at the completion of the study are not necessary for 
study participation. The post treatment biopsy will only be requested to study why your tumor does 
not respond the treatment.
Group 5: If you are on LY2606368 treatment longer than 4 months, the post-treatment biopsy will 
only be requested, to study why your tumor does not respond the treatment. If your tumor briefly 
responds to LY2606368 less than 4 months, the post treatment biopsy will not be asked. 
BIRTH CONTROL
If you are a woman who is breast feeding or pregnant, you may not take part in the study because 
we don’t know how this medicine would affect your baby or your unborn child. All participants 
of reproductive capability must agree to use both a barrier method and a second method of birth 
control during the study and for four months after you finish study treatment.  If you are a man 
who is sexually active, you and your female partner must agree to use medically accepted barrier 
methods of contraception (e.g., male or female condom) during the study and for 4 months after 
you finish the study treatment, even if oral contraceptives are also used.  If you think that you, or 
your female partner if you’re a man, are pregnant, you should tell your study doctor or nurse at 
once.  
Effective forms of birth control include: 
•
abstinence 
•
intrauterine device (IUD)
•
hormonal [birth control pills, injections, or implants]
•
tubal ligation
•
vasectomy
WHAT TESTS WILL BE DONE ON MY SAMPLES?
In addition to the tests that we will conduct to determine whether you are having side effects or if 
you are responding to the study therapy, we will also collect samples from you for purposes of 
research only.  All of your samples collected for research purposes on this study (such as the tumor 
and normal tissue) may be used to look for specific changes in the DNA in tumors that could be 
used to develop new ways of diagnosing and treating cancer. DNA (also called deoxyribonucleic 
acid) in the cells carries genetic information and passes it from one generation of cells to the next 
– like an instruction manual. Normal tissue contains the DNA (instructions) that you were born 
with, DNA in tumor cells has changed – or mutated – and we think that change in the DNA is what 
causes tumors to form and to grow. 
To look at your DNA, we may do what is called “whole genome sequencing.”  This is where we 
will do special tests in the lab to look at the entire sequence, or order, of how your DNA is put 
together.  This is what makes you unique.  
To determine which parts of the DNA have mutated, we will compare the DNA in your tumor cells 
to DNA from your normal cells. We will then analyze the results from similar tumors to see if 
there are any changes in the DNA that are common to a particular type of tumor. To examine the

tumor and normal tissue we may use several different techniques depending on the type of tissue 
we collect. These could include growing cell lines (cells which keep dividing and growing in the 
laboratory, sometimes for years allowing us to continually study those cells), xenograft studies 
(placing or growing cells in another animal, such as mice), and looking in detail at the parts of the 
genes that produce specific proteins.
However, you should know that the analyses that we perform in our laboratory are for research 
purposes only; they are not nearly as sensitive as the tests that are performed in a laboratory that 
is certified to perform genetic testing or testing for routine clinical care. For these reasons, we will 
not give you the results of the research tests done on your research samples in most cases.  There 
may be exceptions to what we share with you. 
In the unlikely event that we discover a finding that is believed to be clinically important based on 
medical standards at the time that we first analyze your results, we will contact you.  This could 
be many years in the future. We will ask you to have an additional tube of blood drawn to verify 
the findings we have seen in our lab. If the results are verified, you will be re-contacted and offered 
a referral to a genetic healthcare provider to discuss the results. In the event that you are removed 
from this study before such findings become available, you must be enrolled on a follow-up study 
in order for us to contact you.  This will enable us to maintain updated contact information for you 
and contact you when such findings become available.
Psychological or Social Risks Associated with Loss of Privacy 
The following general points are indirectly related to your participation in the research study:
1.
Unanticipated medical information: During the course of this investigation, it is possible 
(although not likely) that we will obtain unanticipated information about your health or 
genetic background.
2.
Release of genetic information

Your privacy is very important to us and we will use many safety measures to protect 
your privacy. However, in spite of all of the safety measures that we will use, we 
cannot guarantee that your identity will never become known. Although your genetic 
information is unique to you, you do share some genetic information with your 
children, parents, brothers, sisters, and other blood relatives. Consequently, it may be 
possible that genetic information from them could be used to help identify you. 
Similarly, it may be possible that genetic information from you could be used to help 
identify them. 

Patterns of genetic variation also can be used by law enforcement agencies to identify 
a person or his/her blood relatives. Therefore, your genetic information potentially 
could be used in ways that could cause you or your family distress, such as by 
revealing that you (or a blood relative) carry a genetic disease.

There also may be other privacy risks that we have not foreseen.
This study involves genetic testing on samples.  Some genetic information can help predict 
future health problems of you and your family and this information might be of interest to your 
employers or insurers. The Genetic Information Nondiscrimination Act (GINA) is a federal law 
that prohibits plans and health insurers from requesting genetic information or using genetic

information. It also prohibits employment discrimination based on your health information. 
However, GINA does not address discrimination by companies that sell life insurance, disability 
insurance, or long-term care insurance. GINA also does not protect you against discrimination 
based on an already-diagnosed condition or disease that has a genetic component. 
Who else besides the investigators on this study will know the results of my sample testing?
Once we obtain any of the samples listed above, the investigators take all your personal 
information off those samples and label them with a study code number.  Only the investigators 
on this study know who the sample came from.  The key linking your personal information with 
the code number is kept in a secure computer data base, with access only to the 2-3 research staff 
who will be discussing this study with you.  Once the sample has been labeled with a code, it is 
sent to a variety of NIH laboratories for storage and testing.  No one testing your samples will be 
able to link the results to you personally.  Specimens obtained during your participation in this 
study may be sent for testing to investigators outside of NCI or the NIH.  All samples will be coded 
to protect your privacy and no personal information will be included.  Other investigators on this 
study will have access to limited clinical and biologic data such as age, gender and disease status.
How long will your samples be stored?
The samples collected during this study will be stored for as long as the study is open.  When this 
study is closed, we would like to keep the samples for future research.  We will request your 
permission to do so, later in this consent.
RISKS OR DISCOMFORTS OF PARTICIPATION
What side effects or risks can I expect from being in this study?
LY2606368
As with all treatments, there are several side effects or risks from the treatment provided in this 
study. However, doctors don’t know all the side effects that may happen with this drug, so it is 
important to report any changes that you notice, even if your study team does not ask specifically 
about them. Side effects may be mild or severe. Your study team will give you medicines to help 
lessen side effects. Many side effects go away with those medicines and others may go away soon 
after you stop treatment. In some cases, side effects can be serious, long-lasting, or may never go 
away. In very rare instances, they could cause death.
Just over 100 people have been treated with this study drug.  Based on what these people reported 
the possible side effects are described below: 
Likely

Low white blood cell count (which can increase your risk for infections)

Low red blood cell count

Low platelet count (increases your risk of bleeding)

Nausea

Serotonin Syndrome
There is a potential risk of a condition called serotonin syndrome for participants who use certain 
medications from a class of drugs known as selective serotonin reuptake inhibitors (SSRIs) at the 
same time they’re taking the study drug LY2606368. Serotonin syndrome is a potentially life-
threatening drug reaction that causes the body to have too much serotonin, a chemical produced 
by nerve cells.  Symptoms may include, but are not limited to, agitation or restlessness, severe 
diarrhea, a fast heartbeat, and high blood pressure.  Participants who use SSRIs will be closely 
monitored by their study doctor for any signs and symptoms of serotonin syndrome, and they 
should also be monitored for this condition by their home physician.  Treatment and supportive 
care measures are available to manage serotonin syndrome.
QTc prolongation
There is a potential risk of developing irregular heartbeats on EKG, a condition called QTc 
prolongation, for participants who are taking the study drug LY2606368. This EKG change is a 
potentially life-threatening event. People who have QTc prolongation on EKG are at risk of 
fainting and sudden death. Electrolytes abnormalities increase the risk for developing this change 
on EKG. Your electrolytes and EKG will be closely monitored before and after the study drug 
LY2606368 during the first two months, and then every 3 months until the end of treatment. 
Treatment and supportive care measures are available to manage QTc prolongation.
Myelodysplastic Syndrome (MDS)
MDS is a rare but serious group of disorders caused when something disrupts the production of 
blood cells.  Some types have no known cause, while others occur in response to cancer 
treatments or chemical exposure. Symptoms may include shortness of breath, fatigue, easy 
bruising, and paleness.  Myelodysplastic syndrome may progress to leukemia. Transfusions and 
medications can help manage symptoms, and medications or bone marrow transplants may

lessen the need for transfusion and slow or prevent progression to leukemia.  Although it is not 
yet known that MDS is a risk of LY2606368, there is a possibility that it could contribute to the 
development of MDS in high-risk participants such as those who previously received certain 
types of cancer drugs  or radiation therapy.
Tumor Biopsy
If your doctor determines it is safe we will obtain a piece of your tumor (biopsy) using a needle 
with minimal risk to you.  You will be given local anesthesia (numbing medicine) and a sedative 
prior to the biopsy.  The biopsy will be taken through a needle put through the skin into your tumor.  
Depending upon the location of your tumor, a CT scan may be used to assist the biopsy. After the 
procedure the nurses will watch your blood pressure and other vital signs.  This biopsy is not 
optional and you cannot participate in this study if you do not agree to the biopsy. If the first biopsy 
is too difficult or if you experience too much discomfort as a result of it you will be able to continue 
on the protocol without undergoing the second and third biopsies, which are optional. However, 
an attempt at the first biopsy is needed to enter this study. There are other studies at NIH which 
may also be options for you and which do not involve biopsies.
For group 5, the second biopsy at progression is mandatory for those who responded to 
LY2606368 longer than 4 months. 
Risk of Radiation
During your participation in this research study, you will be exposed to radiation from CT scans.  
The amount of radiation exposure you will receive from these procedures is equal to approximately 
10.1 rem. A rem is a unit of absorbed radiation. 
Every day, people are exposed to low levels of radiation that come from the sun and the 
environment around them.  The average person in the United States receives a radiation exposure 
of 0.3 rem per year from these sources.  This type of radiation is called “background radiation”.  
This study will expose you to more radiation than you get from everyday background radiation. 
No one knows for sure whether exposure to these low amounts of radiation is harmful to your 
body. 
The CT scans that you get in this study will expose you to roughly the same amount of radiation 
as 33.7 years’ worth of background radiation. Being exposed to too much radiation can cause 
harmful side effects such as an increase in the risk of cancer.  The risk depends on how much 
radiation you are exposed to. Please be aware that about 40 out of 100 people (40%) will get cancer 
during their lifetime, and 20 out of 100 (20%) will die from cancer. The risk of getting cancer from 
the radiation exposure in this study is 1 out of 100 (1%) and of getting a fatal cancer is 0.5 out of 
100 (0.5%).
You may not participate in this study if you are pregnant. If you are able to become pregnant, we 
will perform a pregnancy test before exposing you to radiation. You must tell us if you may have 
become pregnant within the previous 14 days because the pregnancy test is unreliable during that 
time.

Blood Sampling 
Risks of blood sampling include bruising or bleeding at the needle site; rarely infection. This is 
treated with bandages, pressure and, if infection, antibiotic medicines. For more information about 
risks and side effects, ask your study team.
CT Scans:
A CT scan is an X-ray procedure where a high-speed computer is used to make multiple images 
or pictures of your body. Sometimes, a contrast dye that contains iodine is administered into one 
of your veins to improve these images. In some cases, people might have an allergic reaction to 
this dye. You will be asked to lie still on a table and at times may have to hold your breath for a 
few seconds in order to avoid blurring the pictures. You may hear a slight buzzing, clicking and/or 
whirring sounds as the CT scanner moves around your body. 
POTENTIAL BENEFITS OF PARTICIPATION
Are there benefits to taking part in this study? 
The aim of this study is to see if this LY2606368 will cause your tumors to shrink.  We do not 
know if you will receive personal, medical benefit from taking part in this study. These potential 
benefits could include shrinking of your tumor or lessening of your symptoms, such as pain, that 
are caused by the cancer.  Because there is not much information about the drug’s effect on your 
cancer, we do not know if you will benefit from taking part in this study, although the knowledge 
gained from this study may help others in the future who have cancer.  
ALTERNATIVE APPROACHES OR TREATMENTS
What other choices do I have if I do not take part in this study? 
Instead of being in this study, you have these options:

Getting treatment or care for your cancer without being in a study

Taking part in another study

Getting comfort care, also called palliative care.  This type of care helps reduce pain, 
tiredness, appetite problems and other problems caused by the cancer.  It does not treat the 
cancer directly.  Instead, it tries to improve how you feel.  Comfort care tries to keep you 
as active and comfortable as possible.
Please talk to your doctor about these and other options. 
STOPPING THERAPY 
Your doctor may decide to stop your therapy for the following reasons:

if he/she believes that it is in your best interest

if your disease comes back during treatment

if you have side effects from the treatment that your doctor thinks are too severe

if new information shows that another treatment would be better for you

If the study drug is no longer available
In this case, you will be informed of the reason therapy is being stopped.
You can stop taking part in the study at any time. However, if you decide to stop taking part in the 
study, we would like you to talk to the study doctor and your regular doctor first.
If you decide at any time to withdraw your consent to participate in the trial, we will not collect 
any additional medical information about you. However, according to FDA guidelines, 
information collected on you up to that point may still be provided to Eli Lilly or designated 
representatives. If you withdraw your consent and leave the trial, any samples of yours that have 
been obtained for the study and stored at the NCI can be destroyed upon request. However, any 
samples and data generated from the samples that have already been distributed to other 
researchers or placed in the research databases cannot be recalled and destroyed.
CONFLICT OF INTEREST
The National Institutes of Health (NIH) reviews NIH staff researchers at least yearly for conflicts 
of interest.  This process is detailed in a Protocol Review Guide. You may ask your research 
team for a copy of the Protocol Review Guide or for more information.  Members of the research 
team who do not work for NIH are expected to follow these guidelines but they do not need to 
report their personal finances to the NIH.
Members of the research team working on this study may have up to $15,000 of stock in the 
companies that make products used in this study.  This is allowed under federal rules and is not a 
conflict of interest. 
The National Institutes of Health and the research team for this study are using LY2606368 
developed by Eli Lilly through a joint study with your researchers and the company.  The 
company also provides financial support for this study.  
USE OF SPECIMENS AND DATA FOR FUTURE RESEARCH
To advance science, it is helpful for researchers to share information they get from studying 
human samples.  They do this by putting it into one or more scientific databases, where it is 
stored along with information from other studies. A researcher who wants to study the 
information must apply to the database and be approved.  Researchers use specimens and data 
stored in scientific databases to advance science and learn about health and disease.  
We plan to keep some of your specimens and data that we collect and use them for future 
research and share them with other researchers. We will not contact you to ask about each of 
these future uses.  These specimens and data will be stripped of identifiers such as name, address 
or account number, so that it may be used for future research on any topic and shared broadly for 
research purposes.  Your specimens and data will be used for research purposes only and will not 
benefit you.  It is also possible that the stored specimens and data may never be used.  Results of 
research done on your specimens and data will not be available to you or your doctor.  It might 
help people who have cancer and other diseases in the future.
If you do not want your stored specimens and data used for future research, please contact us in 
writing and let us know that you do not want us to use your specimens and/or data.  Then any

specimens that have not already been used or shared will be destroyed and your data will not be 
used for future research. However, it may not be possible to withdraw or delete materials or data 
once they have been shared with other researchers.
Genomic Data Sharing
As part of this research study, we will put your genomic data in a large database for broad sharing 
with the research community. These databases are commonly called data repositories. The 
information in this database will include but is not limited to genetic information, race and 
ethnicity, and sex.  If your individual data are placed in one of these repositories, they will be 
labeled with a code and not with your name or other information that could be used to easily 
identify you, and only qualified researchers will be able to access them. These researchers must 
receive prior approval from individuals or committees with authority to determine whether these 
researchers can access the data.
Summary information about all of the participants included in this study (including you) is being 
placed in a database and will be available through open access. That means that  researchers and 
non-researchers will be able to access summary information about all the participants included in 
the study, or summary information combined from multiple studies, without applying for 
permission. The risk of anyone identifying you with this information is very low.
NIH policies require that genomic data be placed in a repository for sharing. Therefore, we 
cannot offer you a choice of whether your data will be shared.  If you do not wish to have your 
data placed in a repository, you should not enroll in this study.
COMPENSATION, REIMBURSEMENT, AND PAYMENT
Will you receive compensation for participation in the study?
Some NIH Clinical Center studies offer compensation for participation in research. The amount 
of compensation, if any, is guided by NIH policies and guidelines.
You will not receive compensation for participation in this study. 
Will you receive reimbursement or direct payment by NIH as part of your participation?
Some NIH Clinical Center studies offer reimbursement or payment for travel, lodging or meals 
while participating in the research. The amount, if any, is guided by NIH policies and guidelines.
On this study, the NCI will cover the cost for some of your expenses.  Some of these costs may be 
paid directly by the NIH and some may be reimbursed after you have paid.  Someone will work 
with you to provide more information.
Will taking part in this research study cost you anything? 
NIH does not bill health insurance companies or participants for any research or related clinical 
care that you receive at the NIH Clinical Center. 

If some tests and procedures are performed outside the NIH Clinical Center, 
you may have to pay for these costs if they are not covered by your insurance 
company.

When results of an NIH research study are reported in medical journals or at scientific meetings, 
the people who take part are not named and identified.  In most cases, the NIH will not release any 
information about your research involvement without your written permission.  However, if you 
sign a release of information form, for example, for an insurance company, the NIH will give the 
insurance company information from your medical record.  This information might affect (either 
favorably or unfavorably) the willingness of the insurance company to sell you insurance.
If we share your specimens or data with other researchers, in most circumstances we will remove 
your identifiers before sharing your specimens or data. You should be aware that there is a slight 
possibility that someone could figure out the information is about you. 
Further, the information collected for this study is protected by NIH under a Certificate of 
Confidentiality and the Privacy Act. 
Certificate of Confidentiality
To help us protect your privacy, the NIH Intramural Program has received a Certificate of 
Confidentiality (Certificate). With this certificate, researchers may not release or use data or 
information about you except in certain circumstances.  
NIH researchers must not share information that may identify you in any federal, state, or local 
civil, criminal, administrative, legislative, or other proceedings, for example, if requested by a 
court.

The Certificate does not protect your information when it:  
1. is disclosed to people connected with the research, for example, information may be used 
for auditing or program evaluation internally by the NIH; or 
2. is required to be disclosed by Federal, State, or local laws, for example, when information 
must be disclosed to meet the legal requirements of the federal Food and Drug 
Administration (FDA); 
3. is for other research;
4. is disclosed with your consent. 
The Certificate does not prevent you from voluntarily releasing information about yourself or your 
involvement in this research. 
The Certificate will not be used to prevent disclosure to state or local authorities of harm to self or 
others including, for example, child abuse and neglect, and by signing below you consent to those 
disclosures. Other permissions for release may be made by signing NIH forms, such as the Notice 
and Acknowledgement of Information Practices consent.
Privacy Act
The Federal Privacy Act generally protects the confidentiality of your NIH medical records we 
collect under the authority of the Public Health Service Act.  In some cases, the Privacy Act 
protections differ from the Certificate of Confidentiality.  For example, sometimes the Privacy Act 
allows release of information from your medical record without your permission, for example, if 
it is requested by Congress. Information may also be released for certain research purposes with 
due consideration and protection, to those engaged by the agency for research purposes, to certain 
federal and state agencies, for HIV partner notification, for infectious disease or abuse or neglect 
reporting,  to tumor registries, for quality assessment and medical audits, or when the NIH is 
involved in a lawsuit.  However, NIH will only release information from your medical record if it 
is permitted by both the Certificate of Confidentiality and the Privacy Act.
POLICY REGARDING RESEARCH-RELATED INJURIES  
The NIH Clinical Center will provide short-term medical care for any injury resulting from your 
participation in research here. In general, no long-term medical care or financial compensation for 
research-related injuries will be provided by the NIH, the NIH Clinical Center, or the Federal

PRÉCIS 
Background:

Checkpoint kinases 1 and 2 (Chk1/2) are major regulators of the cell cycle and are 
intimately associated with the cellular response to DNA damage and repair. Chk1/2 also 
function as the primary mediators of cell cycle arrest in tumors with p53 dysfunction, 
such as high-grade serous ovarian cancer (HGSOC), and triple negative breast cancer 
(TNBC). 

Participants with germline BRCA1 or BRCA2 mutation have inherent defects in DNA 
damage repair pathways. 

Chk1/2 inhibition alone yielded DNA damage and mitotic catastrophe preclinically, even 
in the absence of DNA damage by external agents in tumors with underlying DNA repair 
dysfunction.

The second-generation Chk1/2 inhibitor, LY2606368, yielded safety and preliminary 
single agent activity in advanced cancer participants.

We hypothesize that LY2606368 will result in clinical benefit in participants with 
gBRCAm-associated breast or ovarian cancers, and HGSOC and TNBC with low genetic 
risk. 
Objectives:

To determine the objective response rate (CR+PR) of single agent LY2606368 in patients 
with gBRCAm-associated breast or ovarian cancer, HGSOC and TNBC with low genetic 
risk.

To determine the safety and toxicity, and progression-free interval (PFI) of LY2606368 
in pretreated participants.

To determine biochemical changes in the DNA damage repair and cell cycle check point 
pathways in tumor and blood samples in response to treatment.  

To determine potential resistance mechanisms to LY2606368 treatment in HGSOC. 
Eligibility:

Participants with recurrent/refractory BRCA mutant breast or ovarian cancer, HGSOC, 
and TNBC, for whom there remains no standard curative measures. 

A documented deleterious germline or somatic BRCA mutation for breast or ovarian 
cancer participants enrolling in Cohort 1.

Negative BRCA mutation testing or negative family history of hereditary breast and 
ovarian cancer syndrome for HGSOC (Cohort 2).

Negative BRCA mutation testing or negative family history of hereditary breast and 
ovarian cancer syndrome for TNBC (Cohort 3).

Effective with amendment I (version date 4/24/2017), mCRPC, Cohort 4 was closed. 

Negative BRCA mutation testing or negative family history of hereditary breast and 
ovarian cancer syndrome for recurrent platinum-resistant HGSOC with measurable and 
biopsiable disease (Cohort 5).

Negative BRCA mutation testing or negative family history of hereditary breast and 
ovarian cancer syndrome for recurrent platinum-resistant HGSOC with measurable but 
without biopsiable disease (Cohort 6).

Amendment Version Date: 12/02/2020

Participants must be off prior chemotherapy, radiation therapy, hormonal therapy, or 
biological therapy for at least 4 weeks. 

ECOG performance status 0-2 and adequate organ and marrow function.
Design:

This is an open label, single arm phase II trial to examine activity of LY2606368 in 
participants in the 6 independent cohorts (Cohorts 1-6). 

LY2606368 will be dosed at the RP2D of 105 mg/m2 IV once every 14 days of a 28day- 
cycle.  

Research samples including whole blood, CTCs, and tumor biopsies will be obtained for 
PD endpoints at baseline, Cycle 1 Day 15 (6-24hr post-2nd dose), and/or at progression in 
all participants. Tumor biopsies will not be performed in Cohort 6.

Participants (Cohorts 1-3, 5 and 6) will be evaluated every two cycles for response using 
RECIST v1.1 and every cycle for safety using CTCAE v4.0.

1.2
BACKGROUND AND RATIONALE
Approximately 15% of high grade serous ovarian cancers (HGSOC) are deficient in homologous 
recombination (HR) DNA double strand break (DSB) repair due to germline BRCA1/2 mutation 
(gBRCAm) 1. Acquired defects in the HR pathway are found in another approximately 35%2-4. 
The BRCA-like behavior has been described based on clinical and molecular features that 
parallel with gBRCAm-associated cancers’ characteristics. The major clinical BRCA-like 
behavior identified is susceptibility to platinums and other DNA damaging agents5-7. Some of the 
molecular events described in BRCA-like behavior include BRCA1 promoter methylation, 
Fanconi F methylation, upregulation of EMSY, and loss or reduction of proteins necessary for 
HR, such as RAD51, ATM, ATR, and Chk24,8-11. The BRCA-like phenotype requires p53 
mutation, which secondarily leads to abnormal cell cycle checkpoint function12. Emerging data 
also indicate that half of metastatic castrate-resistant prostate cancer (mCRPC) patients have p53 
mutations and approximately 20% of them have alterations in genes involved in DNA damage 
repair pathways, such as BRCA1, BRCA2 or ATM13,14. Further, Small and colleagues recently 
presented at 2015 ASCO that upregulation of genes involved in cell cycle checkpoints were 
identified in tumor samples from mCRPC patients who were resistant to abiraterone or 
enzalutamide, suggesting DNA damage repair and cell cycle pathways as potential therapeutic 
targets
   Checkpoint kinases (Chk1/2) are major regulators of the cell cycle and are intimately 
associated with the cellular response to DNA damage and repair (Figure 1). When damaged 
DNA is present, Chk1 maintains genomic integrity by stalling cell cycle progression thereby 
providing time for the appropriate repair to occur15. Chk1 functions as the primary mediator of 
cell cycle arrest in tumors with mutant p53, such as HGSOC and triple negative breast cancer 
(TNBC)16,17. When Chk1 protein is depleted, more replication origins are activated than the 
replication apparatus can tolerate in early S phase, resulting in slowed and arrested DNA 
replication forks and DNA DSB18. In p53-deficient tumor cells, loss of Chk1 results in DNA 
damage in the absence of the G1/S and G2/M checkpoints. Cells then proceed prematurely into 
mitosis with incompletely replicated and broken chromosomes, arresting in prometaphase19. In 
addition, Chk1 phosphorylates multiple downstream targets that regulate DNA replication, 
chromosome alignment, spindle checkpoints, and exit from cytokinesis20. Cells deficient in Chk1 
have increased spontaneous chromosome missegregation. These cells lose the ability to recruit 
spindle checkpoint protein BubR1 to kinetochores and fail to activate the spindle checkpoint in 
response to misaligned chromosomes20. This finding suggests that Chk1 is essential for stable 
attachment of mitotic spindles to metaphase chromosomes. Thus, it is postulated that effective 
Chk1 inhibition alone can generate DNA damage and mitotic catastrophe. These functions of 
Chk1 indicate that its inhibition should negatively affect the viability of tumor cells, even in the 
absence of DNA damage by external agents.

BRCA1/2 and Chk1/2 pathway interactions
The concept of synthetic lethality has been applied to preclinical and clinical models that are 
deficient in a DNA damage repair pathway21-23. Following DNA damage, BRCA1 is involved in 
the control of cell cycle checkpoints24, which represents another potential reason to target 
BRCA1 and Chk1/2 therapeutically. Chk1 is activated by ATR in response to stressors such as 
replication stress, chemotherapeutic agents, and single strand breaks (SSBs); whereas, Chk2 is 
activated by ATM in response to ionizing radiation, chemotherapeutics, or DSBs25. Activation of 
Chk1/2 leads to arrest at different phases of the cell cycle depending on the specific kinase 
activated, allowing DNA repair to occur. Yarden et al26 demonstrated BRCA1 regulates the 
expression, phosphorylation and cellular localization of Chk1. The presence of phosphorylated 
BRCA1 affects the expression and localization of Cdc25C, a downstream target of Chk126. 
   Mateo et al recently presented preliminary findings from a phase II trial of olaparib 
monotherapy in mCRPC at 2015 AACR. All patients with mCPRC had been treated previously 
with docetaxel; 48/50 patients (96%) had been previously treated with abiraterone, and 20 
patients (58%) with cabazitaxel. Sixteen of 49 evaluable patients experienced objective response 
with a RR of 32.7%. Furthermore, homozygous deletions and/or deleterious mutations in DNA 
repair genes were identified in 30.6% of evaluable patients (15/49), with the majority in BRCA2 
and ATM mutations. Among these fifteen patients, 13 (86.7%) responded to olaparib, suggesting 
targeting DNA repair in mCRPC offers novel direction of treatment in heavily pre-treated 
mCRPC patients.

BRCA1 function and thus may be a suitable target for therapy in gBRCAm-associated breast or 
ovarian cancers, and tumors with underlying DNA repair and cell cycle check points 
dysfunction. In this regard, patients with gBRCAm have an inherent defect in DNA damage 
response, which should predispose them to the synergistic effect of Chk1 inhibition leading to 
cell cycle progression, crisis and cell death. Based upon these mechanistic considerations and our 
early clinical activity findings from a current study, we believe it is reasonable to test clinical 
activity of Chk1/2 inhibitor on gBRCAm-associated and tumors with BRCA-like phenotype. 
LY2606368, a second-generation Chk1/2 inhibitor
Preclinical data from Lilly indicates LY2606368 behaves mechanistically as a DNA-damaging 
agent, a cell cycle checkpoint 1/2-inhibitor, and a cell-cycle disruptor when used in vitro as a 
single agent, in ovarian (Ov) and breast (Br) cancer (Ca) cell lines (LY Investigator’s Brochure 
[IB] 2016). 
Preclinical Efficacy Pharmacology Summary
LY2606368 is a second generation, potent ATP-competitive inhibitor of Chk1 and Chk2. 
LY2606368 inhibits the activity of Chk1 with an IC50 of 1 nM and an inhibition binding constant 
(Ki) of 0.5 nM in an in vitro enzyme assay. Chk2 and the p90S6 kinases (Rsk) were inhibited by 
LY2606368 at an IC50 of less than 10 nM. Further, LY2606368 yielded single agent cytotoxicity 
with submicromolar concentration in BrCa cell lines including BRCA mutated BrCa and TNBC 
lines (Figure 2). LY2606368 has been shown to inhibit tumor growth when used either as 
monotherapy or in combination with other cytotoxic agents. The single agent activity of 
LY2606368 is related to the ability of this molecule to potently inhibit Chk1 thereby effectively 
interfering with its function to support normal DNA replication.  This occurs via regulation of 
origin firing and/or aspects of chromosomal dynamics during mitosis that are thought to be 
dependent upon Chk1 kinase activity.

The preclinical studies in mouse models showed single agent activity of LY2606368 as 
monotherapy in ovarian tumor xenografts27 (Figure 3 and Figure 4). Treatment of tumor-
bearing animals with LY2606368 alone on a 3 day per week for 3 weeks treatment schedule 
resulted in profound growth inhibition such that greater than 80% inhibition was observed at 
doses of 12mg/kg in both subcutaneous and orthotopic models. Moreover, the studies in the 
orthotopic SKOV3 OvCa model (BRCA1/2 wild type) demonstrated that treatment with 
LY2606368 not only robustly inhibited growth of the primary tumor but also significantly 
reduced the incidence of metastases and accumulation of ascites fluid (Figure 5). Overall, these 
animal studies indicate the potential therapeutic benefit of LY2606368 monotherapy in OvCa.

Identification of a gene signature highly represented in TNBC
Patients with BRCA mutation-associated and BRCA-like ovarian and/or breast cancers consist of 
approximately 50% of HGSOC3,4 and 20% of TNBC28, respectively, for a minimum estimate of 
approximately 14,000 at-risk women per year. High-throughput gene expression studies have 
identified gene signatures characteristic of TNBC subtypes. These studies have shed important 
insights regarding the molecular architecture of TNBC. Among these findings, dysregulation of 
the tumor suppressor p53 and Rb pathways is found in the majority of TNBC samples leading to 
alterations in the expression of genes involved in proliferation, DNA synthesis, DNA damage 
and repair, cell cycle regulation, mitosis and apoptosis. Deeb and colleagues reported a core

Mice bearing intraperitoneal  SKOV3-Luc 
tumors were treated with either 0.2mL of

p53/Rb gene signature (Tag signature) that was highly expressed in a genetic mouse model of 
TNBC, but did not identify ER+ tumors, and which was prognostic of poor outcome29. This gene 
signature consists of approximately 150 genes highly enriched for DNA synthesis, DNA 
proliferation, cell-cycle, mitosis and apoptosis regulatory genes. This signature was also highly 
enriched in gene expression profiles of TNBC cells lines as reported by Neve et al30. Based upon 
this analysis, human TNBC cells and a murine TNBC cell line were used to identify potential 
therapeutic targets based upon the Tag signature. A custom siRNA library screen was used to 
determine which of the TNBC-Tag signature genes are critical for growth or survival of TNBC 
cells. Among these signature genes were Chk1/2 and ribonucleotide reductases 1 and 2 (RRM1 
and RRM2; Figure 6)31. Chk1 has been reported to be highly expressed in TNBC. Further 
validation studies confirmed that siRNAs that inhibited Chk1 also yielded cytotoxicity in TNBC 
cells31.

Table 2. Dose limiting toxicities in Part A of study JTJA
The maximum tolerated dose (MTD) of Schedule 1 was determined to be 40 mg/m2 and the 
MTD of Schedule 2 was determined to be 105 mg/m2. The schedule 2 MTD was selected as the 
recommended Phase 2 dose (RP2D) for LY2606368 monotherapy based on 
1) Clinical PK data demonstrating potentially efficacious LY2606368 systemic exposure ranges; 
clinical PK data (Table 4) coincided with the predicted AUC (0-72) range (1008 to 3533 
ng•hr/mL; median predicted AUC[0-72] = 1896 ng•hr/mL) to achieve the maximal tumor 
response after LY2606368 monotherapy in human, 
2) Acceptable safety profile for each schedule, and 
3) Increased patient convenience of fewer days of dosing. 
The most common serious adverse events (SAE)s related to LY2606368 monotherapy (schedule 
2: 105mg/m2 every 14 days) were hematologic toxicities or complications resulting from 
neutropenia, leukopenia, or thrombocytopenia. Neutropenia was the most frequent toxicity and 
was observed at all doses and schedules of LY2606368. Overall, 89% of patients experienced 
neutropenia and/or leukopenia deemed related to LY2606368 treatment, with 71% grade 4 
neutropenia. In general, neutrophil counts nadir on day 8 and grade 4 neutropenia was often 
transient (< 5 days). Febrile neutropenia was reported in 11% of patients, and no patients have 
discontinued or died because of febrile neutropenia. Patients who have grade 4 neutropenia or 
febrile neutropenia received (peg)filgrastim according to 2006 ASCO G-CSF guideline32. 
Related grade 4 thrombocytopenia has been observed in 6% of patients and two patients (2%) 
had clinically significant bleeding (epistaxis and hematochezia) in the setting of 
thrombocytopenia. Other hematologic adverse events (AEs) included anemia (49% [all grades]; 
19% [grade 3/4]) and thrombocytopenia (46% [all grades]; 22% [grade 3/4]). Two patients (2%) 
had clinically significant bleeding with thrombocytopenia. Non-hematologic toxicity occurred at 
a lower frequency and was predominantly grade 1 or 2. Fatigue, nausea and headache are the 
only non-hematologic AEs that are related to study drug treatment occurring in >10% of patients. 
Pharmacokinetics
Interim PK data were available from study JTJA including 27 patients across the dose range of 
10 to 50 mg/m2 on Schedule 1 (days 1-3 q 14 days), 18 patients across the dose range of 40 to 
130 mg/m2 on Schedule 2 from Part A, 31 patients in Part B (day 1 q 14 days), and 70 patients in 
Part C (day 1 q 14 days). LY2606368 exposure increased in a dose-dependent manner from 10 to 
130 mg/m2 on day 1 of cycle 1 across both schedules of administration. The systemic clearance 
(CL) and volume of distribution at steady state (Vss) were consistent after repeat administration 
in Parts B and C, suggesting time-independent PK behavior. A moderate-to-large degree of

Abbreviated Title: LY Chk1/2 Inhibitor 
Amendment Version Date: 12/02/2020
interpatient PK variability (percentage coefficient of variation [CV%]) in LY2606368 systemic 
CL was also observed (Table 3). 
Table 3. Pharmacokinetic Summary from Parts B and C of study JTJA (RP2D 105mg/m2 
every 2 weeks schedule; source: 2016 IB)
Furthermore, 44% of the noncompartmental AUC(0-72) values calculated were equal to or greater 
than the median AUC(0-72) (1896 ng*hr/mL; based on the Calu-6 xenograft PK/PD model to 
achieve the maximal tumor response in humans) predicted to correlate with the the maximal 
tumor response after LY2606368 monotherapy, while 95% of the AUC(0-72) values calculated 
were greater than the lower end of the 90% PI (1008 ng*hr/mL) for maximum tumor response. 
A preliminary population PK analysis is available from study JTJA (n=146).  There is low-to-
moderate degree of interpatient variability across PK parameters of the model (CV% range: 23-
51%). The population PK model also predicted that LY2606368 exposure following 
administration of 105mg/m2 (AUC(0-72) of  2112 ng*hr/mL; 90% PI: 1179-3434 ng*hr/mL) is 
greater than the AUC(0-72)  noncompartmental (model independent) determined values (Table 3). 
In addition, the population PK analysis supports a body surface area (BSA)-based dose regimen 
is appropriate for LY2606368 administration. The BSA distribution based on specific 
noncompartmental PK parameters (Cmax and AUC(0-72)) showed overlap of baseline BSA values 
across the 4 exposure quartiles for Cmax and AUC(0-72), and similar BSA distributions across each 
exposure quartile following administration of 105mg/m2 (Figure 7).

Clinical drug interactions
The potential drug-drug interaction was evaluated in human liver microsomes. In vitro model 
showed LY2606368 inhibited CYP1A2 (Ki =1.6 uM =767 ng/mL) and CYP2D6 (Ki =2.8 uM 
=1343 ng/mL), but showed no inhibition of CYP2C8, CYP2C9, CYP2C19, CYP2B6, or 
CYP3A4 over a range of concentration of 0.103 to 25 uM. However, in simulations of human 
PK models, the increase in CYP2D6 substrate AUC and Cmax ratios were <1.2 for both substrates 
at RP2D (105mg/m2) of LY2606368 (See 2016 IB for further information).  Overall, the data 
suggest the potential for a clinical drug-drug interaction is minimal.
Preliminary efficacy data
In part A (dose escalation) of study JTJA, two of the 45 patients (4.4%) had PR: one patient with 
anal squamous cell cancer (SCC) and one had SCC of the head and neck. Fifteen of 45 patients 
(33%) achieved RECIST SD, ranging 1.2 to 6.7 months, six of whom had SCC. 
Preliminary activity of LY2606368 in HGSOC (NCI study 14-C-0156; NCT02203513)
Platinum-resistant recurrent HGSOC 
Patients with high grade serous ovarian cancer (HGSOC) often are initially responsive to 
platinum-based chemotherapy and then become increasingly resistant with more lines of therapy 
33.  However, once a patient is platinum resistant or refractory there is not a consensus regarding 
which therapeutic agent is preferred.  Pegylated liposomal doxorubicin (PLD), gemcitabine, 
topotecan, taxanes, and etoposide are all commonly used in this setting.  In platinum-resistant 


 19

Amendment Version Date: 12/02/2020
patients who had received 1 to 2 previous lines of therapy, bevacizumab when added to 
paclitaxel, PLD, or topotecan chemotherapy increased the overall response rate (ORR) from 12% 
to 27% 34.  Agents that are approved by the U.S. FDA for patients who have received at least 1 
previous line of chemotherapy include topotecan, PLD, and bevacizumab in combination with 
paclitaxel, PLD, or topotecan. More recently, exploiting defects in homologous recombination 
repair pathways with PARP inhibitors has been shown to be an effective strategy for treating 
ovarian cancer.  Olaparib obtained accelerated approval for patients with deleterious germline 
BRCA mutated advanced ovarian cancer after 3 or more lines of chemotherapy.  The RR (n=137) 
was 34%, and median duration of response was 7.9 months (Kim et al. 2015).  However, no 
agents are specifically approved for patients who do not harbor a BRCA1/2 mutation and have 
had at least 2 lines of previous chemotherapy, and new treatment options are needed.  
     LY2606368 inhibits checkpoint kinase 1, a multifunctional protein kinase that controls DNA 
replication, mediates cell cycle arrest, and is essential for homologous recombination repair 
(McNeely et al. 2014).  In phase 1 testing, durable objective clinical responses, including a CR, 
were observed 35).  The mechanism of action of LY2606368 is distinct from traditional cytotoxic 
agents, and it is anticipated that the mechanisms of sensitivity and resistance will also be 
different.  This makes LY2606368 a potentially attractive agent for the treatment of patients with 
HGSOC whose disease has progressed after at least 2 lines of chemotherapy.  
Preliminary clinical evidence of LY2606368 in heavily pretreated HGSOC  
     Preliminary results from 32 heavily pretreated HGSOC patients have been presented at the 
European Society of Medical Oncology meeting in October 2016, including 7 patients in Cohort 
1 (patients with a documented BRCA mutation) and 25 patients in Cohort 2 (patients with a 
negative family history of hereditary breast ovarian cancer syndrome, or negative germline 
BRCA mutation test).  Transient grade 4 neutropenia was observed in 69% of patients and 
resolved to less than or equal to grade 2 within 8 days after onset.  Two patients (6%) had febrile 
neutropenia. Only one patient had dose reduced to 80mg/m2. Other toxicities included decreased 
white blood cell count (78%), anemia (66%), and decreased platelet count (34%).  
Nonhematologic AEs were generally mild and included fatigue, nausea, vomiting, and diarrhea 
(9% each).  One patient experienced Grade 3 diarrhea and vomiting during infusion.
     Among 20 evaluable patients in HGSOC (Cohort 2), there were 7 confirmed PRs, for an ORR 
of 7 of 20 (35%). Patients had a median of 5 previous therapies (range:  1 to 13). Of the 20 
evaluable patients, 15 had platinum-resistant or platinum-refractory disease.  Five of 15 patients 
had a PR for an ORR of 33%.  The interim median duration of response is 6 months (3+ to 9 
months).  The numbers of previous therapies for the responders were 2, 4, 5, 6, and 13.  An 
additional 5 patients with platinum-resistant or platinum-refractory disease had SD ≥4 months 
for an overall clinical benefit rate of 66% (10 of 15).  Six of 10 patients who had a PR or SD ≥4 
months had received previous bevacizumab. Notably, an expected RR for this patient population 
with existing agents is approximately 15% (unpublished meta-analysis conducted by Eli Lilly in 
2 lines+ ovarian cancer) . None of the 6 evaluable patients in Cohort 1 achieved CR or PR, but 4 
(67%) achieved SD lasting at least 4 months, for a DCR of 67%. However, our BRCA mutant 
patient cohort, in which all patients received prior PARP inhibitors, did not show response to 
LY2606368, suggesting CHK1/2 inhibition alone may not reverse the observed PARP inhibitor 
resistance. Figure 8 presents a plot of best responses for target lesions by patient, among patients 
treated with LY2606368.

     The emerging data for LY2606368 suggest that this compound may demonstrate substantial 
improvement in heavily pretreated HGSOC patients with BRCA wild type on the basis of the 
clinically significant endpoint of RR.  In particular, the preliminary data in patients with 
platinum-resistant disease, an area of high unmet need, are favorable.  There are currently no 
agents approved by the FDA for patients with platinum-resistant disease without germline BRCA 
mutation who have progressed after at least 2 previous chemotherapy regimens. Although the 
LY2606368 data are limited, they are superior to historical response rates.  For this reason, we 
are opening the new cohort 6 for BRCA wild type platinum-resistant recurrent HGSOC - the 
same patient population as cohort 5 but without biopsiable disease - to facilitate acquiring 
efficacy data of LY2606368 prior to launching a randomized phase 2/3 trial.
In addition, we recently opened the new cohort 5 for BRCA wild type patients with platinum-
resistant recurrent HGSOC with mandatory paired biopsies (baseline and at progression) to study 
potential response/resistance mechanisms and also to confirm the preliminary monotherapy 
activity. LY2606368 is clinically active, but not all tumors respond and most actually progress 
while on therapy. Clinical activity to date is associated with the BRCA wild type subpopulation, 
but this may be a correlate; resistance may involve interactions with the PARP pathway, NBS1 
in DNA repair (unpublished data, Murai and Pommier, DTB/CCR) and likely other as yet 
unknown pathways. Development of agents that target cell cycle and DNA damage repair is 
critical given ~50% of HGSOCs have defects in these pathways. Based on our preliminary 
studies, the hypothesis to be tested in this cohort 5 is that Chk1/2 inhibition may have novel 
resistance mechanism(s) such as NBS1 deficiency in a subset of HGSOCs. By comparing tumor 
samples from pre-LY2606368 and at progression, and between responders and non-responder on 
clinical trial, we expect to identify novel targets for HGSOC patients, delineate mechanisms of 
Chk1/2 inhibition resistance and identify biomarkers predictive of response to Chk1/2 inhibition, 
which will ultimately assist in stratifying patients for these therapies.

Summary
Understanding more about the interaction of cell cycle checkpoint inhibition in BRCA mutation-
associated and/or BRCA-like breast or ovarian cancers, exploring novel therapeutic trial 
strategies, and defining potential predictive biomarkers of response or resistance, are critical to 
advance therapeutic directions in these important but rare subsets of women’s malignancies. We 
hypothesized that therapeutic inhibition of cell cycle check point and DNA damage repair 
functions will yield benefit in patients with BRCA mutation-associated breast or ovarian cancer, 
HGSOC, and TNBC at low genetic risk.  Additionally, genomic studies have revealed clinically 
actionable alterations in DNA repair pathways, including p53 mutation in mCRPC.  These 
aberrations are therapeutic targets in both BRCA mutation and BRCAwt disease.  Chk1/2 
inhibition is a novel treatment strategy in mCRPC where other treatment options become limited 
over time.  In order to evaluate cell cycle inhibition in mCRPC, a subset of patients with soft 
tissue disease independent of BRCA mutation status will be enrolled (Cohort 4).  We 
hypothesized therapeutic inhibition of Chk1 cell cycle and DNA damage repair functions will 
yield benefit in patients with pretreated mCPRC.  A positive signal in this pilot single arm study 
will lead to discussions of appropriate next steps (e.g. RP2) or combination with other DNA 
repair inhibitor(s) to broaden evaluation of this agent. Additionally, effective with amendment I, 
the Cohort 4 (mCRPC) was closed due to slow accrual.

Imaging Studies 
Every participant must have a CT scan of chest, abdomen and/or pelvis prior to receiving 
treatment. PET/CT alone is not sufficient. These tests are deemed medically indicated to 
establish baseline disease characteristics. This must be completed within 16 days prior to 
enrollment. Participants with CT contrast hypersensitivity in the presence of appropriate pre-
medication may be followed by MRI with gadolinium per investigator-approval. A contrast CT 
or MRI of brain may be requested if a participant has advanced breast cancer or has symptoms or 
physical examination findings that suggest a risk of brain metastases. In some participants, an 
MRI, PET, bone scans, or ultrasound may be appropriate to include in disease monitoring and 
may be included in addition to the baseline CT scan.

STUDY IMPLEMENTATION
3.1
STUDY DESIGN
This is an open label, non-randomized phase II pilot trial to examine activity of LY2606368 in 
participants in 6 independent cohorts: 
1) Women with BRCA mutant breast or ovarian cancer 
2) HGSOC at low genetic risk 
3) TNBC at low genetic risk
4) mCRPC with or without BRCA mutation: Effective with Amendment I (version date 
4/24/2017), Cohort 4 was closed to accrual. 
5) Recurrent platinum-resistant HGSOC at low genetic risk
6) Recurrent platinum-resistant HGSOC at low genetic risk without biopsiable disease
Participants will be evaluated at baseline and prior to each cycle by history and physical 
examination (H&P).  Laboratory studies will be performed prior to each drug administration. In 
cohorts 1 – 3, 5 and 6, participants will be evaluated every two cycles by imaging studies using 
RECIST criteria (CT scan or other as appropriate). In the mCRPC cohort, participants will be 
evaluated by imaging studies using RECIST criteria (CT scan and other imaging as appropriate) 
and technetium 99 bone scan36 every 3 cycles.  All participants in this cohort will have baseline 
CT and technetium 99 bone scan imaging.  As per the Prostate Cancer Clinical Trials Working 
Group 2 recommendations, every effort should be made to keep participants on treatment with 
LY2606368 for at least 12 weeks36 and thus for the purposes of this cohort, participants should 
be evaluated every 3 cycles. Effective with Amendment I (version date 4/24/2017), mCRPC 
cohort 4 was closed to accrual.
Participant adherence to drug treatment and reporting of adverse effects will be reviewed by 
history. 
LY2606368 is administered intravenously once every 14-days in each 28-day cycle.  
Administration of LY2606368 may be delayed up to 7 days due to holidays, inclement weather, 
conflicts, or similar reasons. The timing of subsequent administrations is then adjusted to 
maintain a 14 days-interval.  For safety reasons, LY2606368 may not be administered with less 
than a 14-days interval.

DRUG ADMINISTRATION
See Study Schema:
The RP2 dose of 105 mg/m2 LY2606368 administered by IV over 1 hour  (+15 minutes)  once 
every 14 days will be used.  Administration of LY2606368 may be delayed up to 7 days due to 
holidays, inclement weather, conflicts, or similar reasons. The timing of subsequent 
administrations is then adjusted to maintain a 14 days-interval.  For safety reasons, LY2606368 
may not be administered with less than a 14-days interval.
Participants should avoid taking concomitant medications that are known or suspected to cause 
prolonged QTc or Torsades de Pointes (Appendix B) 12 hours before through 12 hours after 
administration of LY2606368 and, if possible, alternative agents should be considered.  
     
Participants will continue therapy until documentation of progressive disease, limiting toxicity 
(3.3), intercurrent medical issues, or participant withdrawal. Participants with CR will 
discontinue therapy two cycles past a radiographically confirmed CR (see 6.2.4 for guidance), 
and will then be followed actively in clinic every 4 weeks with reassessment noninvasive 
imaging on an every 12 week schedule until progression or withdrawal.  Participants with signs 
or symptoms of clinical progression may be imaged earlier in order to provide optimal care. 
Palliative radiation therapy may be considered for symptom and/or pain control in consultation 
with Radiation Oncology, only for those who continue to have clinical benefit from LY2606368 
treatment at the PI’s discretion (see section 14.1.2for guidance of concurrent radiation therapy 
and LY2606368). 
     
Participants will be contacted over the phone or assessed in person at least once weekly during 
the first cycle of treatment. Subsequent follow up will be at least monthly, with the start of each 
new cycle, and then during follow up according to the defined schedule (see 3.4: Study 
Calendar). 
     
Pre-cycle and off-treatment AE assessments will be done at a scheduled clinic visit. Off-study 
assessments will be performed within 30 days of stopping study treatment over the phone or at a 
clinic visit.

Hematologic Toxicity  
Hold LY2606368 for participants with grade 3 or 4 hematologic toxicities until they recover to 
grade 2 or better. The participants at a high-risk for bleeding; e.g., concurrent use of anti-
coagulation, may hold LY2606368 until platelets recover to grade 1 or better. Blood counts will 
be repeated every other day until resolution to grade 2 or better.

Abbreviated Title: LY Chk1/2 Inhibitor 
Amendment Version Date: 12/02/2020
3.3.1.1
Neutropenia:  

Prophylactic and/or therapeutic growth factor support will be given following the ASCO 
practice guidelines32. 

Participants who experience grade 3 or 4 neutropenia or fever during neutropenia and are 
not receiving growth factor support can be supplemented with filgrastim 5 mcg/kg/day 
until ANC is greater than 3,000/ml, or pegfilgrastim 6mg at the discretion of the team. 

If recurrent grade 3 or 4 neutropenia (> 7 days) is refractory to growth factor support, 
then LY2606368 should be dose reduced to the next lower dose level.

A subsequent event of grade 4 neutropenia (> 7 days) or fever during neutropenia, while 
on therapeutic or prophylactic filgrastim growth factor support, will necessitate 
discontinuation of a study drug.

Participants with ANC ≤1500/mL on day 1 of a cycle may receive filgrastim 5 mcg/kg 
for a period of 3-5 days or pegfilgrastim 6mg to avoid treatment delays and risk of dose 
reduction, if they did not receive growth factor support in the immediately preceding 
cycle.  

Prophylactic antibiotics may be considered for use in participants that have experienced 
febrile neutropenia on the study or participants deemed at higher risk for febrile 
neutropenia by the investigators.
3.3.1.2
Thrombocytopenia:

Asymptomatic grade 3 or 4 thrombocytopenia lasting < 7 days will not result in drug 
discontinuation. 

Grade 3 or 4 thrombocytopenia > 7 days or any thrombocytopenia requiring platelet 
transfusion for bleeding will result in dose reduction to the next lower dose level.

The participants at a high-risk bleeding, e.g., concurrent use of anti-coagulation may hold 
LY2606368 until platelets recover to grade 1 or better (>75,000/mm3). 
3.3.1.3
Anemia:

The first line response to symptomatic anemia is introduction of red cells, and 
consideration of growth factor support if participants require recurrent red cells 
transfusion.

Symptomatic anemia should be treated with red blood cell transfusion and is 
recommended if the hemoglobin falls below 8 g/dL. 

The initiation of erythropoietic therapy for the management of chemotherapy-induced 
anemia follows the American Society of Hematology/ASCO clinical practice guidelines 
(http://www.asco.org).

If grade 3/4 anemia is refractory to red cell transfusion and growth factor support within 
3 weeks, then LY2606368 should be dose reduced to the next lower dose level.

Drug will be reinitiated upon resolution of toxicity to grade 1 or better or as qualified below. 
Delay of treatment due to recovery may not persist longer than 3 weeks. Once a participant has a 
dose reduction for toxicity, the dose will not be increased back to the starting dose. Treatment 
will be discontinued if participants require the second dose reduction due to the occurrence of the 
same events. 
3.3.2
QTc Prolongation
On study monitoring:  

ECGs will be performed before and at the end of infusion of each LY2606368 (within 
30min +/- 20min), every two weeks x2, every 4 weeks x1, then every 3 months.

For a single QTcF value of >500 ms, LY2606368 must be held. Electrolytes will be 
corrected and ECGs followed at least once per week, until QTcF falls below 480 ms. 

When drug is restarted after the QTcF prolongation has resolved within 3 weeks, ECGs 
(and electrolytes) should be followed every 2 weeks x2, every 4 weeks x1, then every 3 
months.

Serum potassium levels should be maintained ≥3.6 mEq/L, and serum magnesium and 
serum calcium should be kept within normal range to reduce the risk of QTcF 
prolongation. Some ovarian cancer participants who have had exposure to cis- and 
carboplatin may have persistent hypomagnesemia or hypokalemia despite replacement to 


 32
CC Protocol #: 14-C-0156

Amendment Version Date: 12/02/2020
the point of induction of diarrhea (if not within a normal range). Such participants will be 
closely monitored during the treatment, with IV potassium or additional dose of 
magnesium repletion. 
3.3.3
Non-hematologic Toxicity
The participant will be removed from the study if a grade 4 non-hematologic toxicity occurs with 
the following exceptions:

Asymptomatic hyperuricemia/hypouricemia/hypophosphatemia/hyponatremia with 
optimal repletion

Asymptomatic hypomagnesemia with optimal repletion 

Asymptomatic hypocalcemia, or hypokalemia with optimal repletion; however, 
asymptomatic grade 4 hypokalemia not corrected to grade 1 or 0 within 48 hours despite 
optimal repletion will result in discontinuation of study drug.
Subsequent grade 3 asymptomatic electrolyte toxicities that could be controlled with 
standard medications will not have dose reduction.  However, asymptomatic grade 3 
hypokalemia not corrected to grade 1 or 0 within 48 hours despite optimal repletion will 
result in dose reduction.

1Administration of LY2606368 may be delayed up to 7 days due to holidays, inclement weather, conflicts, or similar reasons. The 
timing of subsequent administrations is then adjusted to maintain a 2-week interval. For safety reasons, LY2606368 may not be 
administered with less than a 2-week interval.
2Performed every other week during Cycle 1 and every cycle (+/- one day due to holiday, inclement weather, or similar reasons) for 
safety measures in subsequent cycles.  Phone follow up for symptom assessment every week during Cycle 1
3Performed before (anytime prior to Prexasertib infusion start)  and after (within 30min +/- 30min) infusion of LY2606368
4Performed every two weeks (+/- one day due to holiday, inclement weather, or similar reasons). CBC will be repeated on Cycle 1 
Day 8 (+/- one day due to holiday, inclement weather, or similar reasons) during Cycle 1 to check ANC nadir. May be omitted on 
Cycle 1 Day 1 if completed within 3 days of screening/baseline.
5 For cohorts 1-3, second and at progression biopsies are optional, and strongly encouraged. For cohort 5, the second biopsy (= 
biopsy at progression) is mandatory for the responders (defined by CR/PR or SD >4 completed cycles of therapy. No biopsies are 
performed for cohort 6.

11End of treatment visit will occur approximately 30 days after the last dose of study drug. If the participant cannot return to the 
Clinical Center for this visit, a request will be made to collect required clinical labs (specify as needed) from a local physician or 
laboratory.  If this is not possible, participants may be assessed by telephone for symptoms.  
3.5
COST AND COMPENSATION
NIH does not bill health insurance companies or participants for any research or related clinical care that participants receive at the 
NIH Clinical Center.  If some tests and procedures performed outside the NIH Clinical Center, participants may have to pay for these 
costs if they are not covered by insurance company.  Medicines that are not part of the study treatment will not be provided or paid for 
by the NIH Clinical Center.
3.5.1
Compensation
Participants will not be compensated on this study.
3.5.2
Reimbursement 
The NCI will cover the costs of some expenses associated with protocol participation.  Some of these costs may be paid directly by the 
NIH and some may be reimbursed to the participant/guardian as appropriate.  The amount and form of these payments are determined 
by the NCI Travel and Lodging Reimbursement Policy.

CRITERIA FOR REMOVAL FROM PROTOCOL THERAPY AND OFF STUDY CRITERIA
Prior to documenting removal from study, effort must be made to have all subjects complete a safety visit approximately 30 days 
following the last dose of study therapy.
3.6.1
Criteria for removal from protocol therapy
In the absence of treatment delays due to adverse events, treatment may continue until one of the following criteria applies:

Disease progression

Intercurrent illness that prevents further administration of treatment

Participant requests to be withdrawn from an active therapy. 

Participant withdraws consent. In this event, the reasons for withdrawal will be documented and the participant will be 
taken off study at that time.

If participants are non-compliant with the protocol guidelines, they may be removed
from the study at the discretion of the PI.

Unacceptable adverse events as defined in section 3.3.3

Positive pregnancy test

PI discretion: clinical disease progression
3.6.2
Off-Study Criteria

Completed study follow-up period

Participant requests to be withdrawn from study

Death

Start of another anti-cancer therapy

Lost to follow up 
3.6.3
Lost to follow up 
A participant will be considered lost to follow-up if he or she fails to return for one scheduled treatment visit and is unable to be 
contacted by the study site staff. 
The following actions must be taken if a participant fails to return to the clinic for a required study visit:


 37
CC Protocol #: 14-C-0156
Abbreviated Title: LY Chk1/2 Inhibitor 
Amendment Version Date: 12/02/2020

The site will attempt to contact the participant by the methods described below to reschedule the missed visit within 7 days of 
the missed visit, counsel the participant on the importance of maintaining the assigned visit schedule, and ascertain if the 
participant wishes to and/or should continue in the study.

Before a participant is deemed lost to follow-up, the investigator or designee will make every effort to regain contact with the 
participant within 7 days (a minimum of 3 contact attempts using the participant’s preferred method of contact via phone, 
email, or a combination of both; and if necessary, a letter sent through a trackable delivery service to the participant’s last 
known mailing address. These contact attempts should be documented in the participant’s medical record or study file.

Should the participant continue to be unreachable, he or she will be considered to have withdrawn from the study with a 
primary reason of lost to follow-up.
4
CONCOMITANT MEDICATIONS/MEASURES

Other cancer chemotherapy, radiation therapy, immunotherapy, or investigational agents may not be administered to 
participants while they are receiving LY2606368 on this study.  

Concomitant use of medications generally known to cause prolonged QTc or Torsades de Pointes (Appendix B) are not 
allowed within 12 hours before and after the infusion of LY2606368.

Preliminary results suggest that drug–drug interactions may be possible although clinical drug-drug interaction is unlikely, 
when LY2606368 is co-administered with medications that are classified as sensitive cytochrome P450 (CYP)1A2 and 
CYP2D6 substrates.  This should be considered by the investigator when LY2606368 is administered to participants requiring 
treatment with sensitive CYP1A2 and CYP2D6 substrates, such as duloxetine, alosetron, and desipramine, or with CYP1A2 
and CYP2D6 substrates that have a narrow therapeutic range, such as theophylline, tizanidine, and thioridazine.

Because LY2606368 interacts with multiple 5-hydroxytryptamine (5-HT) receptors, participants should be monitored closely 
by a home physician or investigators at CCR for any signs and symptoms of serotonin syndrome.  
Combined use of selective serotonin reuptake inhibitor (SSRI)s or change SSRIs without wash-out could potentially lead to 
serotonin syndrome. Serotonin syndrome is a potentially life threatening drug reaction due to excess of serotonergic activity at 
central nervous system (CNS) and peripheral serotonin receptor, and symptoms and signs may include agitation or restlessness, 
severe diarrhea, tachycardia, and hypertension.  If observed, appropriate treatment (e.g., cyproheptadine or octreotide) may be 
used as a treatment.

Alternative antiemetic medications available at the Clinical Center that will not prolong QTc interval, not affect 5-HT 
receptors, and not affect CYP1A2 and CYP2D6 substrates are listed below.  These medications may be used for symptomatic 
relief of nausea: dexamethasone (glucocorticoid; CYP3A subfamily inducer), methylprednisolone (glucocorticoid; CYP3A 


 38
CC Protocol #: 14-C-0156
Abbreviated Title: LY Chk1/2 Inhibitor 
Amendment Version Date: 12/02/2020
subfamily substrate and inducer), lorazepam (benzodiazepine; undergoes phase II metabolism by glucuronidation; 85 to >90% 
protein bound), granisetron (serotonin 5 HT3 receptor antagonist with least potential for perturbing cardiac conduction among 
the pharmacological class; CYP3A4 substrate) 

Supportive care measures and symptomatic treatment for any treatment-associated toxicity may be instituted once the first 
signs of toxicity occur and should be recorded in the participant’s chart.

CORRELATIVE STUDIES AND BIOSPECIMEN COLLECTION
5.1
CORRELATIVE STUDIES FOR RESEARCH/PHARMACODYNAMIC STUDIES
5.1.1
Rationale for Correlative Studies
The goal of the correlative studies is to identify potential predictive and proof-of-concept biomarkers of Chk1/2 inhibitor in BRCA 
mutation-associated and BRCA-like breast and ovarian cancers. In the context of this study, participants of Cohorts 1-3 will undergo 
one mandatory and two optional (highly encouraged) biopsies to be used to characterize the effects that LY2606368 upon the biology 
of both the tumor and the stroma. The timing of biopsies (baseline, C1d15 [6-24hr post-2nd dose], and at progression) has been defined 
to get tumor samples to investigate the biochemical changes by replication stress and in response to treatment. 
In addition, we will study potential resistance mechanisms of LY2606368 in responders with recurrent platinum-resistant HGSOC. 
For cohort 5, all participants will undergo pretreatment biopsy.  The mandatory second biopsy (=at progression) will be done only for 
the responders (defined by CR/PR or SD > 4 months). The second biopsy may be performed if the sum of target lesions increases 15 
+/- 4% from the best response before confirmed PD by RECIST v1.1 criteria, due to holidays, inclement weather, conflicts, or similar 
reasons. 
These tumor biopsies will be obtained percutaneously or per vagina through Interventional Radiology as long as considered minimal 
surgical risk. Participants must agree to the mandatory biopsy prior to signing consent and enrolling on study. Participants may 
withdraw their consent for optional biopsies after enrolling on the study and treatment will not be prejudiced. Molecular profiling, 
genomic sequencing and/or immune subsets panel will be used to evaluate target and related pathways. Further detailed molecular 
analysis of tumor and stroma may lead to an understanding of the mechanisms mediating clinical response, tumor progression, and 
toxicities.


 39
CC Protocol #: 14-C-0156
Abbreviated Title: LY Chk1/2 Inhibitor 
Amendment Version Date: 12/02/2020
Blood samples for circulating tumor cells (CTCs) and immune panel analyses will be collected at the following time points: at 
baseline, C1d15 (6-24hr post-2nd dose), and at progression for all study participants (cohorts 1-3, 5 and 6). Research samples 
(supernatant and pellet) to test for HR deficiency will be collected from participants who undergo either therapeutic or diagnostic 
thoracentesis or paracentesis while on study. Samples may be saved, and anonymized for LY2606368 concentration measurement in 
the body fluid.
All participants on the study are requested to submit a block of tissue or 20 paraffin-capped unstained slides from a recent resection or 
barring that, from the original surgery. All efforts will be made to obtain these samples to achieve the secondary objectives.  
5.1.2
Tumor biopsies
5.1.2.1
Rationale
Cohorts 1-3: The on-study biopsy and the optional second biopsy are necessary for the execution of the critical translational endpoints 
evaluating proof of concept and demonstration of mechanism and activity.
Cohort 5: Paired baseline and at progression biopsies are necessary to investigate potential resistance mechanisms in clinical 
responders to LY2606368
5.1.2.2
Timing* 
Cohorts 1-3: Biopsies will be performed at the following times:

Mandatory – after consent, prior to treatment on cycle 1 day 1

Optional - cycle 1 day 15 (6-24hr post-2nd dose)

Optional - at the time of progression 
Cohort 5: Biopsies will be performed at the following times:

Mandatory – after consent, prior to treatment on cycle 1 day 1

Mandatory second biopsy for the responders (CR, PR and SD > 4 completed cycles of therapy) at progression.

Amendment Version Date: 12/02/2020
*Biopsies may be not performed on the specific dates and times due to the following reasons, including but not limited to, delayed 
recovery of hematologic toxicities, delayed clinic schedule, or national holidays.
Attempts will be made to obtain four cores if safe and feasible, which will be frozen for research studies. Two 3- millimeter punch 
biopsies of skin will be acceptable in lieu of 18 gauge core biopsies for participants with skin involvement. Inability to get tissue with 
a reasonable attempt will not preclude treatment and the participant will remain eligible for all other translational components. The use 
of imaging to facilitate biopsies will be decided upon by members of the interventional radiology team. Should CT scans be needed 
for biopsy, a limit of 10 scans for each procedure will be observed to minimize radiation exposure to the participant. 
The biopsies (up to three cores) are to be immediately embedded, frozen, and stored in the Lee lab at -800C on site according to our 
laboratory SOP (Appendix C). The schedule for the biopsies will be made with Special Procedures (Dr. Brad Wood). 

For groups 1-3 and 5, members of the Lee lab will be on call to receive and embed biopsies: jayakumar.nair@nih.gov, Phone 
(301) 451-8403, beeper 102-11155. 
Each participant sample set will be assigned a unique participant identifier. The protocol scientific investigator(s) handling the 
samples will be blinded as to the participant identification, participant data and outcome. 
Frozen biopsies will be sectioned, stained, and subjected to tissue lysate array analysis as below (section 5.1.3.1). 
If an attempt at biopsy is unsuccessful, the participant will still be eligible for treatment and the subsequent biopsies will be foregone. 
Biopsy material will be prioritized for proteomics. The remaining tissue will be released for additional testing prioritized to genomic 
sequencing, cell cycle check point pathways analyses, and immunohistochemistry, in that order.
5.1.3
Laboratory Correlative Studies
5.1.3.1
Tissue proteomic Analysis
Protein microarrays will be employed to quantitate activated and inactive signaling components of the DNA damage repair and cell 
cycle check point pathway proteins before and at two weeks of therapy. Analysis of specific proteins and their activation status allows 
interrogation of the Chk1/2 pathway and collateral pathways at multiple nodes. Target proteins can include but not limited to: ATM,

Saliva Samples
Group 4 mCRPC cohort only: a one-time saliva sample will be collected anytime during the study as a source of normal tissue for 
genomics comparison. Each saliva sample will be collected in one Oragene Saliva Kit at room temperature, and Dr. Figg’s lab will be 
paged for pick-up at 102-11964.  Dr. Figg’s lab will barcode the sample, remove participant identifier, and send the sample to Dr. 
Meltzer’s lab, Bldg. 37, Rm 6138 via courier.  Participants will be instructed not to eat, drink, smoke or chew gum for 30 minutes before 
giving their saliva sample.  Sequencing of DNA will be performed by the Genetics Branch (Drs. Khan/Meltzer).
5.1.3.3
RNAseq or next generation sequencing and genomic analysis
RNAseq or exome sequencing will be done to investigate potential predictive biomarkers in responders and non-responders to 
LY2606368 in the Sequencing facility, Frederick National Laboratory for Cancer Research. Tumor biopsies will be obtained at baseline 
(mandatory), 6-24hr after the second dose (optional), and time of disease progression (optional for Cohorts 1-3 but mandatory for cohort 
5 responders). 
The results of molecular studies conducted using specimens are for research purposes only and will not be disclosed to individual 
subjects. The exception to this is potential incidental findings that are deemed medically significant and actionable. The policy for this 
disclosure is outlined below and in the consent form for this study.


Subjects will be contacted if a clinically actionable gene variant is discovered. Clinically actionable findings for the purpose of 
this study are defined as disorders appearing in the American College of Medical Genetics and Genomics recommendations for 
the return of incidental findings that is current at the time of primary analysis. (A list of current guidelines is maintained on the 
CCR intranet: https://ccrod.cancer.gov/confluence/display/CCRCRO/Incidental+Findings+Lists).
Subjects will be contacted at this time with a request to provide a blood sample to be sent to a CLIA certified laboratory which 
has an FDA approved test for that mutation. If the research findings are verified in the CLIA certified lab, the subject will be 
referred to the CCR Genetics Branch for the disclosure of the results.  

This is the only time during the course of the study that incidental findings will be returned. No interrogations regarding clinically 
actionable findings will be made after the primary analysis. 

Contact information must be maintained on subjects to have their results returned. If a subject’s participation in the study ends 
prior to the primary analysis, they should be enrolled on study 04-C-0165, a standard of care protocol, in order to allow for post 
study contact for the dissemination of any incidental findings and the maintenance of contact information.

Subject’s genetic data may be deposited in a database such as dbGaP. Although there is controlled access to such a database, 
such a submission carries theoretical risks of revealing the identity of the subject. This is discussed in the consent.
5.1.3.4

Radiomics
5.1.6.1
Rationale
Tissue based biomarkers remain the gold standard for pharmacodynamics studies but need to be carefully calibrated to the most 
informative tumor region, which is currently very difficult to achieve in a multi-site heterogeneous disease such as recurrent ovarian 
cancer. 
Professor Evis Sala’s lab at the University of Cambridge in U.K. has been a leading expert in the quantitative assessment of image 
features, known as radiomics, using their artificial intelligence tools for (a) automatic whole volume tumor segmentation and (b) 
deriving predictive and prognostic models of response and outcome. Radiomics biomarkers therefore could serve as “virtual biopsies” 
and may provide biomarkers reporting changes in both tumor and microenvironment during therapy and have the potential to 
personalize treatment by objective assessment of these effects. This project is supported by the Biomarkers Consortium by Foundation 
of National Institutes of Health.  All imaging, reports, and clinical information will be de-identified.

5.1.6.3 Procedure 

An independent review of all scans of ovarian cancer participants will be conducted by Professor Sala’s lab in order to develop 
and validate precise and robust radiogenomics biomarkers to optimize response assessment. 

Copies of all imaging assessments including unscheduled visit scans will be collected on an ongoing basis and sent to 
the collaborators listed in 5.1.6.2.

Prior radiation therapy reports for participants (at baseline) and information on any lesions that were biopsied to provide a 
tumor sample for study entry will be provided to allow the selection of appropriate target lesions.

Results of this scan review will not be communicated to Investigators to make a clinical decision.
5.2
SAMPLE STORAGE, TRACKING AND DISPOSITION
Samples will be ordered in CRIS and tracked through a Clinical Trial Data Management system.  Should a CRIS screen not be 
available, the CRIS downtime procedures will be followed.  Samples will not be sent outside NIH without appropriate approvals 
and/or agreements, if required.
Each participant sample set will be assigned a unique participant identifier in the recipient lab with bar coding in the Clinical 
Pharmacology Program (CPP) and Lee laboratories and the scientific investigator handling and performing analyses on the samples 
will be blinded as to the sample source, participant data, and outcome.  There will be no date identifiers on the samples. Samples will 
be grouped for scientific analyses. If a participant needs to have a malignant effusion tapped for diagnostic or therapeutic purposes, a 
sample will be collected for research. At the end of the protocol, samples will be stored for potential further analysis as new 
information becomes available (only for those subjects who consented to future optional studies). Any new use of identified or coded 
samples, specimens, or data will undergo prospective and continuing IRB review and approval.  
Samples, and associated data, will be stored in the locations listed above unless the participant withdraws consent. If researchers have 
samples remaining once they have completed all studies associated with the protocol, they must be returned to Dr. Lee’s laboratory or 
to the CPP repository. Samples can only be saved at completion of study for future use if subjects consent. Access to these samples 
will only be granted following IRB approval of an additional protocol, granting the rights to use the material.

Abbreviated Title: LY Chk1/2 Inhibitor 
Amendment Version Date: 12/02/2020
If, at any time, a participant withdraws from the study and does not wish for their existing samples to be utilized, the individual must 
provide a written request. Following receipt of this request, the samples will be destroyed (or returned to the participant, if so 
requested). The PI will record any loss or unanticipated destruction of samples as a deviation. Reporting will be per the requirements 
of section 7.2.
5.2.1
Clinical Pharmacology Program 
5.2.1.1
Procedures for sample data collection for the Clinical Pharmacology Program: 

All samples sent to the Clinical Pharmacology Program (CPP) will be barcoded, with data entered and stored in LabMatrix. 
This is a secure program, with access to LabMatrix limited to defined CPP personnel, who are issued individual user accounts. 
Installation of LabMatrix is limited to computers specified by Dr. Figg. These computers all have a password restricted login 
screen. 

LabMatrix creates a unique barcode ID for every sample and sample box, which cannot be traced back to participants without 
LabMatrix access. The data recorded for each sample includes the participant ID, name, trial name/protocol number, time 
drawn, cycle time point, dose, material type, as well as box and freezer location. Participant demographics associated with the 
clinical center participant number are provided in the system. For each sample, there are notes associated with the processing 
method (delay in sample processing, storage conditions on the ward, etc.). 
5.2.1.2
Procedures for sample storage at the Clinical Pharmacology Program: 

Barcoded samples are stored in barcoded boxes in a locked freezer at either -20oC or - 80oC according to stability 
requirements. These freezers are located onsite in the CPP and offsite at NCI Frederick repository facilities in Frederick, MD. 
Visitors to the laboratory are required to be accompanied by laboratory staff at all times. 

Access to stored clinical samples is restricted. Samples will be stored until requested by a researcher named on the protocol. 
All requests are monitored and tracked in LabMatrix. All researchers are required to sign a form stating that the samples are 
only to be used for research purposes associated with this trial (as per the IRB approved protocol) and that any unused samples 
must be returned to the CPP. It is the responsibility of the NCI Principal Investigator to ensure that the samples requested are 
being used in a manner consistent with IRB approval. 

Following completion of this study, samples will remain in storage as detailed above. Access to these samples will only be 
granted following IRB approval of an additional protocol, granting the rights to use the material.

CC Protocol #: 14-C-0156
Abbreviated Title: LY Chk1/2 Inhibitor 
Amendment Version Date: 12/02/2020

Sample barcodes are linked to participant demographics and limited clinical information. This information will only be 
provided to investigators listed on this protocol, via registered use of LabMatrix. It is critical that the sample remains linked to 
participant information such as race, age, dates of diagnosis and death, and histological information about the tumor, in order 
to correlate genotype with these variables.
5.3
SAMPLES FOR CORRELATIVE STUDIES ANALYSIS
5.3.1
Management of Correlative Studies Results 
The analyses performed in various NCI laboratories under this protocol are for research purposes only. Independently of the research 
testing, we will provide guidance and referral (within the NIH or outside) to participants requesting additional counseling and testing.
Any comparisons involving biochemical changes from baseline to after treatment will be considered exploratory, and reported as such, 
without formal adjustment for multiple comparisons. Furthermore, since this study is mainly pilot in intent, the findings will be 
reported in that context. Any such evaluations will be done with exploratory intent, without adjustment for multiple comparisons, and 
with the results reported in that context.

DATA COLLECTION AND EVALUATION 
6.1
DATA COLLECTION
The PI will be responsible for overseeing entry of data into an in-house password protected electronic system (C3D) and ensuring data 
accuracy, consistency and timeliness. The principal investigator, associate investigators/research nurses and/or a contracted data 
manager will assist with the data management efforts. Primary and final analyzed data will have identifiers so that research data can be 
attributed to an individual human subject participant.
All adverse events (AEs), including clinically significant abnormal findings on laboratory evaluations, regardless of severity, will be 
followed until return to baseline or stabilization of event. 
AEs will be documented from the first study intervention, Study Day 1, through 30 days after the subject received the last dose of the 
study agent. Beyond 30 days after the last intervention, only adverse events which are serious and related to the study intervention 
need to be recorded.

CC Protocol #: 14-C-0156
Abbreviated Title: LY Chk1/2 Inhibitor 
Amendment Version Date: 12/02/2020
An abnormal laboratory value will be considered an AE if the laboratory abnormality is characterized by any of the following:

Results in discontinuation from the study

Is associated with clinical signs or symptoms 

Requires treatment or any other therapeutic intervention

Is associated with death or another serious adverse event, including hospitalization. 

Is judged by the Investigator to be of significant clinical impact
If any abnormal laboratory result is considered clinically significant, the investigator will provide details about the action taken with 
respect to the test drug and about the participant’s outcome.
An enrollment log will be maintained in the regulatory binder/file; and source documents, including a family history questionnaire 
(Error! Reference source not found.) will be stored in the research record for each participant.
Quality assurance requires maintaining complete records on each participant treated on the protocol, including primary documentation 
(e.g., laboratory reports, X-ray reports, scan reports, pathology reports, physician notes, etc.) that confirms the following:

The participant met each eligibility criterion.

Signed informed consent was obtained prior to treatment. (An on-study confirmation of eligibility form will be filled out 
before entering the study.)

Documentation of specific dates and times of all treatments, doses administered, and the reason for any dose modification. 

Toxicity was assessed according to protocol (see section 6.3)

Response was assessed according to protocol (X-ray, scan, lab reports, dated notes on measurements, and clinical assessment, 
as appropriate).

NCI Drug Accountability Records were kept for each participant.
Clinical data will be entered in a secure electronic database, NCI C3D database, and hard copies will be stored in locked, secured 
areas.  Completed eligibility checklists, participant information/registration forms, and blood sample flow sheets will also be stored.  
Copies of all records of serious adverse events will be kept in the research record.

Amendment Version Date: 12/02/2020
Complete records must be maintained on each participant, including the hospital chart with any supplementary information obtained 
from outside laboratories, radiology reports, or physician's records.  These records will serve as the primary source material that forms 
the basis for the research record.  All relevant data will also be entered in a computer database from which formal analyses will be 
done.  
The primary source documentation will include: on-study information, including participant eligibility data and participant history; 
flow sheets, records of adverse events, specialty forms for pathology, radiation, or surgery; and off-study summary sheets, including a 
final assessment by the treating physician.
End of study procedures: Data will be stored according to HHS, FDA regulations and NIH Intramural Records Retention Schedule 
as applicable. 
Loss or destruction of data: Should we become aware that a major breach in our plan to protect subject confidentiality and trial data 
has occurred,  this will be reported expeditiously per requirements in section 7.2.1.

6.3
RESPONSE CRITERIA
For the purposes of this study, participants should be re-evaluated for response every 2 cycles (+/- 7 days) for Cohorts 1-3, 5, and 6.  
In addition to a baseline scan, confirmatory scans should also be obtained 4 weeks (+/- 7 days) following initial documentation of 
objective response.  The timing of subsequent re-evaluation for response is then adjusted to continue every 2 cycles (+/- 7 days). 
Participants who have been on study four years or longer should be re-evaluated for response every 3 cycles (+/-7 days).
Response and progression will be evaluated in this study using the new international criteria proposed by the revised Response 
Evaluation Criteria in Solid Tumors (RECIST) guideline (version 1.1)39.  Changes in the largest diameter (unidimensional 
measurement) of the tumor lesions and the shortest diameter in the case of malignant lymph nodes are used in the RECIST criteria. 
For group 4, participants will be assessed primarily by CT scan of the chest, abdomen and pelvis and by technetium 99 bone scan at 
baseline.  Participants will undergo CT imaging, technetium 99 bone scintigrapy (and research imaging if applicable) every 12 weeks 
(+/- 4 days).  Response and progression will be evaluated in this study using the new international criteria proposed by the revised 
Response Evaluation Criteria in Solid Tumors (RECIST) guideline (version 1.1)39 and Prostate Cancer Clinical Trials Working Group 
criteria (PCWG2)36. [Effective with Amendment I (version date 4/24/2017), mCRPC cohort 4 was closed to accrual.]  Changes in the 
largest diameter (unidimensional measurement) of the tumor lesions and the shortest diameter in the case of malignant lymph nodes 
are used in the RECIST criteria.
6.3.1
Definitions
Evaluable for toxicity:  All participants will be evaluable for toxicity from the time of their first treatment with LY2606368.
Evaluable for objective response: Only those participants 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 participants will have their 
response classified according to the definitions stated below.  (Note:  Participants who exhibit objective disease progression prior to 
the end of cycle 1 will also be considered evaluable.)
Evaluable Non-Target Disease Response:  Participants who have lesions present at baseline that are evaluable but do not meet the 
definitions of measurable disease, have received at least one cycle of therapy, and have had their disease re-evaluated will be 
considered evaluable for non-target disease.  The response assessment is based on the presence, absence, or unequivocal progression 
of the lesions.

Amendment Version Date: 12/02/2020
6.3.2
Disease Parameters
Measurable disease:  Measurable lesions are defined as those that can be accurately measured in at least one dimension (longest 
diameter to be recorded) as:

By chest x-ray: >20 mm;

By CT scan:
o
Scan slice thickness 5 mm or under: as >10 mm 
o
Scan slice thickness >5mm:  double the slice thickness

With calipers on clinical exam: >10 mm. 
All tumor measurements must be recorded in millimeters (or decimal fractions of centimeters).
Malignant lymph nodes.  To be considered pathologically enlarged and measurable, a lymph node must be >15 mm in short axis when 
assessed by CT scan (CT scan slice thickness recommended to be no greater than 5 mm).  At baseline and in follow-up, only the short 
axis will be measured and followed.
Non-measurable disease.  All other lesions (or sites of disease), including small lesions (longest diameter <10 mm or pathological 
lymph nodes with ≥10 to <15 mm short axis), are considered non-measurable disease.  Bone lesions, leptomeningeal disease, ascites, 
pleural/pericardial effusions, lymphangitis cutis/pulmonitis, inflammatory breast disease, and abdominal masses (not followed by CT 
or MRI), are considered as non-measurable.
Note:  Cystic lesions that meet the criteria for radiographically defined simple cysts should not be considered as malignant lesions 
(neither measurable nor non-measurable) since they are, by definition, simple cysts.
‘Cystic lesions’ thought to represent cystic metastases can be considered as measurable lesions, if they meet the definition of 
measurability described above. However, if non-cystic lesions are present in the same participant, these are preferred for selection as 
target lesions.
Target lesions.  All measurable lesions up to a maximum of 2 lesions per organ and 5 lesions in total, representative of all involved 
organs, should be identified as target lesions and recorded and measured at baseline.  Target lesions should be selected on the basis of 
their size (lesions with the longest diameter), be representative of all involved organs, but in addition should be those that lend 


 54
CC Protocol #: 14-C-0156
Abbreviated Title: LY Chk1/2 Inhibitor 
Amendment Version Date: 12/02/2020
themselves to reproducible repeated measurements.  It may be the case that, on occasion, the largest lesion does not lend itself to 
reproducible measurement in which circumstance the next largest lesion which can be measured reproducibly should be selected.  A 
sum of the diameters (longest for non-nodal lesions, short axis for nodal lesions) for all target lesions will be calculated and reported 
as the baseline sum diameters.  If lymph nodes are to be included in the sum, then only the short axis is added into the sum.  The 
baseline sum diameters will be used as reference to further characterize any objective tumor regression in the measurable dimension of 
the disease.
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 be recorded at baseline.  Measurements of these lesions are not required, but the 
presence, absence, or in rare cases unequivocal progression of each should be noted throughout follow-up. 
6.3.3
Methods for Evaluation of Measurable Disease
All measurements should be taken and recorded in metric notation using a ruler or calipers.  All baseline evaluations should be 
performed as closely as possible to the beginning of treatment and never more than 4 weeks before the beginning of the treatment.
The same method of assessment and the same technique should 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 unless the lesion(s) being followed 
cannot be imaged but are assessable by clinical exam.
Clinical lesions:  Clinical lesions will only be considered measurable when they are superficial (e.g., skin nodules and palpable lymph 
nodes) and 10 mm diameter as assessed using calipers (e.g., skin nodules).  In the case of skin lesions, documentation by color 
photography, including a ruler to estimate the size of the lesion, is recommended. 
Chest x-ray:  Lesions on chest x-ray are acceptable as measurable lesions when they are clearly defined and surrounded by aerated 
lung.  However, CT is preferable. 
Conventional CT and MRI:  This guideline has defined measurability of lesions on CT scan based on the assumption that CT slice 
thickness is 5 mm or less.  If CT scans have slice thickness greater than 5 mm, the minimum size for a measurable lesion should be 
twice the slice thickness.  MRI is also acceptable in certain situations (e.g. for body scans).  
Use of MRI remains a complex issue.  MRI has excellent contrast, spatial, and temporal resolution; however, there are many image 
acquisition variables involved in MRI, which greatly impact image quality, lesion conspicuity, and measurement.  Furthermore, the 
availability of MRI is variable globally.  As with CT, if an MRI is performed, the technical specifications of the scanning sequences 
used should be optimized for the evaluation of the type and site of disease.  Furthermore, as with CT, the modality used at follow-up 


 55

Amendment Version Date: 12/02/2020
should be the same as was used at baseline and the lesions should be measured/assessed on the same pulse sequence.  It is beyond the 
scope of the RECIST guidelines to prescribe specific MRI pulse sequence parameters for all scanners, body parts, and diseases.  
Ideally, the same type of scanner should be used and the image acquisition protocol should be followed as closely as possible to prior 
scans.  Body scans should be performed with breath-hold scanning techniques, if possible.
Tumor markers:  Tumor markers alone cannot be used to assess response.  If markers are initially above the upper normal limit, they 
must normalize for a participant to be considered in complete clinical response.  Specific guidelines for both CA-125 response (in 
recurrent ovarian cancer) and PSA response (in recurrent prostate cancer) have been published40-42. In addition, the Gynecologic 
Cancer Intergroup has developed CA-125 progression criteria which are to be integrated with objective tumor assessment for use in 
first-line trials in ovarian cancer43.
6.3.4
Response Criteria
6.3.4.1
Evaluation of Target Lesions
Complete Response32: 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 the diameters of target lesions, taking as reference the baseline sum of 
diameters.
Progressive Disease (PD): At least a 20% increase in the sum of the diameters of target lesions, taking as reference the smallest sum 
on study (this includes the baseline sum if that is the smallest on study).  In addition to the relative increase of 20%, the sum must also 
demonstrate an absolute increase of at least 5 mm.  (Note:  the appearance of one or more new lesions is also considered 
progressions).
Stable Disease (SD): Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the 
smallest sum of diameters while on study.
6.3.4.2
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).


 56
CC Protocol #: 14-C-0156
Abbreviated Title: LY Chk1/2 Inhibitor 
Amendment Version Date: 12/02/2020
Note:  If tumor markers are initially above the upper normal limit, they must normalize for a participant to be considered in complete 
clinical response.
Non-CR/Non-PD: 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.  
Unequivocal progression should not normally trump target lesion status.  It must be representative of overall disease status change, 
not a single lesion increase.    
Although a clear progression of “non-target” lesions only is exceptional, the opinion of the treating physician should prevail in such 
circumstances, and the progression status should be confirmed at a later time by the review panel (or Principal Investigator).
6.3.4.3
Evaluation of Best Overall Response
The best overall response is the best response recorded from the start of the treatment until disease progression/recurrence (taking as 
reference for progressive disease the smallest measurements recorded since the treatment started).  The participant's best response 
assignment will depend on the achievement of both measurement and confirmation criteria.

Duration of 
Response
Duration of overall 
response:  The duration 
of overall response is 
measured from the 
time measurement 
criteria are met for CR 
or PR (whichever is 
first recorded) until the 
first date that recurrent 
or progressive disease 
is objectively documented (taking as reference for progressive disease the smallest measurements recorded since the treatment 
started).
The duration of overall CR is measured from the time measurement criteria are first met for CR until the first date that progressive 
disease is objectively documented.
Duration of stable disease:  Stable disease is measured from the start of the treatment until the criteria for progression are met, taking 
as reference the smallest measurements recorded since the treatment started, including the baseline measurements.

TOXICITY CRITERIA
The following adverse event management guidelines are intended to ensure the safety of each participant while on the study.  The 
descriptions and grading scales found in the revised NCI Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 
will be utilized for AE reporting.  All appropriate treatment areas should have access to a copy of the CTCAE version 4.0.  A copy of 
the CTCAE version 4.0 can be downloaded from the CTEP web site 
(http://ctep.cancer.gov/protocolDevelopment/electronic_applications/ctc.htm#ctc_40).

NIH REQUIRED DATA AND SAFETY MONITORING PLAN
7.4.1
Principal Investigator/Research Team 
The clinical research team will meet on a regular basis weekly when participants are being actively treated on the trial to discuss each 
participant. Decisions about dose level enrollment and dose escalation if applicable will be made based on the toxicity data from prior 
participants. 
All data will be collected in a timely manner and reviewed by the principal investigator or a lead associate investigator. Events 
meeting requirements for expedited reporting as described in section 7.2.1 will be submitted within the appropriate timelines.


 60
CC Protocol #: 14-C-0156
Abbreviated Title: LY Chk1/2 Inhibitor 
Amendment Version Date: 12/02/2020
The principal investigator will review adverse event and response data on each participant to ensure safety and data accuracy. The 
principal investigator will personally conduct or supervise the investigation and provide appropriate delegation of responsibilities to 
other members of the research staff. 
7.4.2
Central Reading of Scans
An independent central review (ICR) of all scans for HGSOC participants used in the assessment of tumors using RECIST 1.1 will be 
conducted. Copies of all imaging assessments including unscheduled visit scans will be collected on an ongoing basis and sent to 
the contract research organization appointed by Eli Lilly.
Prior radiation therapy reports for participants (at baseline) and information on any lesions that were biopsied to provide a tumor 
sample for study entry will be provided to allow the selection of appropriate target lesions.
The imaging scans will be reviewed by two independent radiologists using RECIST 1.1 criteria and will be adjudicated if required. 
For each participant, the ICR will define the overall visit response data (CR, PR, SD, PD or not evaluable [NE]) and the relevant scan 
dates for each time point (i.e. for visits where response or progression is/is not identified). If a participant has had a tumor assessment 
which cannot be evaluated then the participant will be assigned a visit response of NE (unless there is evidence of progression in 
which case the response will be assigned as PD).
The management of participants will be based solely upon the results of the RECIST assessment conducted by the Investigator. 
Results of this ICR will not be communicated to Investigators to make a clinical decision.

SPONSOR SAFETY REPORTING
8.1
DEFINITIONS
8.1.1
Adverse Event 
Any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does 
not necessarily have a causal relationship with this treatment. An adverse event (AE) can therefore be any unfavorable and unintended 
sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal 
(investigational) product, whether or not related to the medicinal (investigational) product (ICH E6 (R2))


 61
CC Protocol #: 14-C-0156
Abbreviated Title: LY Chk1/2 Inhibitor 
Amendment Version Date: 12/02/2020
8.1.2
Serious Adverse Event (SAE)
An adverse event or suspected adverse reaction is considered serious if in the view of the investigator or the sponsor, it results in any 
of the following:

Death,

A life-threatening adverse event (see 8.1.3)

Inpatient hospitalization or prolongation of existing hospitalization
o
A hospitalization/admission that is pre-planned (i.e., elective or scheduled surgery arranged prior to the start of the study), 
a planned hospitalization for pre-existing condition, or a procedure required by the protocol, without a serious deterioration 
in health, is not considered a serious adverse event.
o
A hospitalization/admission that is solely driven by non-medical reasons (e.g., hospitalization for patient convenience) is 
not considered a serious adverse event. 
o
Emergency room visits or stays in observation units that do not result in admission to the hospital would not be considered 
a serious adverse event. The reason for seeking medical care should be evaluated for meeting one of the other serious 
criteria.

Persistent or significant incapacity or substantial disruption of the ability to conduct normal life functions

A congenital anomaly/birth defect.

Important medical events that may not result in death, be life-threatening, or require hospitalization may be considered a 
serious adverse drug experience when, based upon appropriate medical judgment, they may jeopardize the patient or subject 
and may require medical or surgical intervention to prevent one of the outcomes listed in this definition.
8.1.3
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 subject 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. (21CFR312.32)
8.1.4
Severity
The severity of each Adverse Event will be assessed utilizing the CTCAE version 4.0.

8.1.5
Relationship to Study Product
All AEs will have their relationship to study product assessed using the terms:  related or not related.  

Related – There is a reasonable possibility that the study product caused the adverse event. Reasonable possibility means that 
there is evidence to suggest a causal relationship between the study product and the adverse event.

Not Related – There is not a reasonable possibility that the administration of the study product caused the event.
8.2
ASSESSMENT OF SAFETY EVENTS
AE information collected will include event description, date of onset, assessment of severity and relationship to study product and 
alternate etiology (if not related to study product), date of resolution of the event, seriousness and outcome. The assessment of severity 
and relationship to the study product will be done only by those with the training and authority to make a diagnosis and listed on the 
Form FDA 1572 as the site principal investigator or sub-investigator.  AEs occurring during the collection and reporting period will be 
documented appropriately regardless of relationship.  AEs will be followed through resolution.
SAEs will be:

Assessed for severity and relationship to study product and alternate etiology (if not related to study product) by a licensed 
study physician listed on the Form FDA 1572 as the site principal investigator or sub-investigator.

Recorded on the appropriate SAE report form, the medical record and captured in the clinical database.

Followed through resolution by a licensed study physician listed on the Form FDA 1572 as the site principal investigator or 
sub-investigator.
For timeframe of recording adverse events, please refer to section 6.1. All serious adverse events recorded from the time of first 
investigational product administration must be reported to the sponsor. 
8.3
REPORTING OF SERIOUS ADVERSE EVENTS
Any AE that meets  protocol-defined serious criteria or meets the definition of Adverse Event of Special Interest that require expedited 
reporting must be submitted immediately (within 24 hours of awareness) to OSRO Safety using the CCR SAE report form.
All SAE reporting must include the elements described in 8.2.

and should be provided as soon as possible.
8.4
SAFETY  REPORTING CRITERIA TO THE PHARMACEUTICAL COLLABORATORS
All events listed below must be reported in the defined timelines to OSROSafety@mail.nih.gov. 
The CCR Office of Sponsor and Regulatory Oversight (OSRO) will send all reports to the manufacturer as described below.
Eli Lilly and Company will be notified via fax at 866-644-1697 or phone (800-545-5979) in a written IND Safety Report (MedWatch, Form 
3500A) as soon as possible and no later than 24 hours of Investigator and/or Institution receiving notification of any serious adverse event 
experienced by a patient participating in the study and receiving study drug. To the extent possible, any AE whose severity and attribution 
require expedited submission of the AE report to the FDA will be sent to Eli Lilly and company in advance of report submission to the 
FDA. 
The Investigative site must also indicate, either in the SAE report or the fax cover page, the causality of events in relation to each of the 
study medications and if the SAE is related to disease progression, as determined by the principal investigator. Any event or hospitalization 
that is unequivocally due to progression of disease, as determined by the PI, will not be reported as an SAE to the FDA, however should be 
communicated to Eli Lilly.
 
A cover page should accompany the MedWatch form indicating the following: 

LY2606368 Investigator Sponsored Study (ISS) 

The investigator IND number assigned by the FDA 

The investigator’s name and address 

The trial name and Eli Lilly Reference number 

Causality 
Follow-up information on SAEs must also be reported by the investigator to NCI and then Eli Lilly within 2 business days for death or life 
threatening or 7 business days for all SAEs for which serious criteria apply after initial receipt of the information. 


 64
CC Protocol #: 14-C-0156
Abbreviated Title: LY Chk1/2 Inhibitor 
Amendment Version Date: 12/02/2020
If follow-up indicates a change in the SAE from serious to fatal or life threatening, this information also needs to be communicated to NCI 
and Eli Lilly within 1 business day. If follow-up indicates a change from serious to non-serious, this information needs to be communicated 
to NCI and Eli Lilly within 5 days. 
All SAEs will be reported to Eli Lilly on a MedWatch form using the following guidelines: 

if there is more than one SAE listed on the MedWatch form, each should be bulleted or numbered 

causality for each SAE must be specified in the narrative section 

the date the site notified NCI and Eli Lilly of the SAE must be specified in the narrative section 

initial and follow-up MedWatch reports should be numbered either in the narrative section or in section G.7 of the MedWatch 
form

REPORTING PREGNANCY
All required pregnancy reports/follow-up to OSRO will be submitted to: OSROSafety@mail.nih.gov and to the CCR PI and study 
coordinator.  Forms and instructions can be found here: 
https://ccrod.cancer.gov/confluence/display/CCRCRO/Forms+and+Instructions 
8.5.1
Maternal exposure
If a patient becomes pregnant during the course of the study, the study treatment should be discontinued immediately, and the 
pregnancy reported to the Sponsor no later than 24 hours of when the Investigator becomes aware of it. The Investigator should notify 
the Sponsor no later than 24 hours of when the outcome of the Pregnancy become known,
Pregnancy itself is not regarded as an SAE. However, congenital abnormalities or birth defects and spontaneous miscarriages that 
meet serious criteria (8.1.2) should be reported as SAEs. 
The outcome of all pregnancies (spontaneous miscarriage, elective termination, ectopic pregnancy, normal birth, or congenital 
abnormality) should be followed up and documented.
8.5.2
Paternal exposure
Male patients should refrain from fathering a child or donating sperm during the study and for 4 months after the last dose of 
LY2606368.

Pregnancy of the patient’s partner is not considered to be an AE. However, the outcome of all pregnancies (spontaneous miscarriage, 
elective termination, ectopic pregnancy, normal birth, or congenital abnormality) occurring from the date of the first dose until 4 
months after the last dose should, if possible, be followed up and documented.
8.6
REGULATORY REPORTING FOR STUDIES CONDUCTED UNDER CCR-SPONSORED IND
Following notification from the investigator, CCR, the IND sponsor, will report any suspected adverse reaction that is both serious and 
unexpected.  CCR will report an AE as a suspected adverse reaction only if there is evidence to suggest a causal relationship between 
the study product and the adverse event.  CCR will notify FDA and all participating investigators (i.e., all investigators to whom the 
sponsor is providing drug under its INDs or under any investigator’s IND) in an IND safety report of potential serious risks from 
clinical trials or any other source, as soon as possible, in accordance to 21 CFR Part 312.32. 
All serious events will be reported to the FDA at least annually in a summary format.

CLINICAL MONITORING
As a sponsor for clinical trials, FDA regulations require the CCR to maintain a monitoring program. The CCR’s program allows for 
confirmation of: study data, specifically data that could affect the interpretation of primary and secondary study endpoints; adherence 
to the protocol, regulations, ICH E6, and SOPs; and human subjects protection. This is done through independent verification of study 
data with source documentation focusing on:

Informed consent process

Eligibility confirmation

Drug administration and accountability

Adverse events monitoring

Response assessment.
This trial will be monitored by personnel employed by a CCR contractor. Monitors are qualified by training and experience to monitor 
the progress of clinical trials. Personnel monitoring this study will not be affiliated in any way with the trial conduct.

10 STATISTICAL CONSIDERATIONS  
The primary objective of this trial is to establish whether LY2606368 is associated with at least a minimal response rate in participants 
with BRCA mutation-associated breast or ovarian cancer (cohort 1), HGSOC at low genetic risk (cohort 2),  TNBC at low genetic risk 
(cohort 3), and mCRPC (cohort 4). Note that, effective with amendment I (version date 4/24/2017), Cohort 4 (mCRPC) was closed 
due to slow accrual. In each of these  cohorts, the study will be conducted using an optimal two-stage phase II trial design43 in order to 
rule out an unacceptably low 5% overall response rate (p0=0.05) in favor of an improved response rate of 25% (p1=0.25). With 
alpha=0.10 (probability of accepting a poor treatment=0.10) and beta = 0.10 (probability of rejecting a good treatment=0.10), each 
cohort of this study will initially enroll 9 evaluable participants, and if 0 of the 9 have a response, then no further participants will be 
accrued in that cohort. If 1 or more of the first 9 participants in a cohort has a response, then accrual would continue until a total of 24 
participants have been enrolled in that cohort. As it may take several weeks to determine if a participant has experienced a response, a 
temporary pause in the accrual to the trial for that cohort may be necessary to ensure that enrollment to the second stage is warranted. 
If there are 1 to 2 responses in 24 participants, this would be an uninterestingly low response rate. If there were 3 or more responses in 
24 participants (12.5%), this would be sufficiently interesting to warrant further study in later trials. Under the null hypothesis (5% 
response rate), the probability of early termination is 63.0%.
Based on the promising results from the HGSOC at low genetic risk cohort 2, the cohort 5 of recurrent platinum-resistant HGSOC will 
use a single stage design, with an early stopping rule for substantially lower than expected efficacy. A total of 36 evaluable 
participants will be enrolled in the new cohort in order to have 89% power to rule out a 20% response rate in favor of an alternative 
response rate of 45%, using a two-tailed 0.05 significance level exact binomial test. In practice, a 95% confidence interval will be 
formed about the reported proportion of responders, and those with clinical benefit, among the 36 evaluable participants to describe 
the results obtained. If there are 13 (or more) responders out of 36 evaluable participants (36.1%), the exact two-sided 95% confidence 
interval about the proportion responding extends from 20.8% to 53.8%, thus ruling out 20% and demonstrating consistency with a 
result of at least 45%. An early stopping rule will be implemented as follows: if after 10 evaluable participants have been enrolled, 
there are 0 to 1 responders, then no further participants will be accrued since the upper one-sided 90% confidence bound on 1/10 is 
0.337. This would mean that there is a reasonably high probability that the true response rate is below 1/3, obtained previously, and 
thus the results may not be as promising as expected.
Also, based on the promising results from the HGSOC at low genetic risk cohort 2, the new cohort 6 of non-BRCA mutated HGSOC 
participants without biopsiable disease will use a single stage design, with an early stopping rule for substantially lower than expected 
efficacy. A total of 35 evaluable participants will be enrolled in the new cohort in order to have 88% power to rule out a 15% response 
rate in favor of an alternative response rate of 40%, using a two-tailed 0.05 significance level exact binomial test. In practice, a 95% 
confidence interval will be formed about the reported proportion of responders, and those with clinical benefit, among the 35 


 67
CC Protocol #: 14-C-0156
Abbreviated Title: LY Chk1/2 Inhibitor 
Amendment Version Date: 12/02/2020
evaluable participants to describe the results obtained. If there are 11 (or more) responders out of 35 evaluable participants (31.4%), 
the exact two-sided 95% confidence interval about the proportion responding extends from 16.9% to 49.3%, thus ruling out 15% and 
demonstrating consistency with a result of at least 40%. An early stopping rule also will be implemented as follows: if after 10 
evaluable participants have been enrolled, there are 0 to 1 responders, then no further participants will be accrued since the upper one-
sided 90% confidence bound on 1/10 is 0.337. This would mean that there is a reasonably high probability that the true response rate 
is below 1/3, obtained previously, and thus the results may not be as promising as expected.
The primary analyses will be done separately by disease cohort, although the response rates may not differ substantially by type of 
disease. In addition, if results are sufficiently similar, the participants from all four-disease types may be evaluated together in a single 
cohort in an exploratory fashion. In each cohort, participants will be divided into groups based on whether they responded (PR+CR) or 
not, or experienced at least some clinical benefit (CR+PR+SD) or not, and when any biologic or biochemical parameters are obtained, 
the changes in these parameters from baseline will be compared between the two groups using a Wilcoxon rank sum test. As these will 
be considered exploratory analyses, the results will not be adjusted for any multiple comparisons but will be considered in the context 
of the hypothesis generating nature of the evaluations. PFI will be estimated using a Kaplan-Meier curve based on all evaluable 
participants, as well as separately by cohort. The PFI at selected points will also be reported, along with associated 80% and 95% 
confidence intervals. Safety and toxicity in this population will be determined by tabulating the toxicity grades identified in the 
participants treated on the trial, by cohort, and describing the findings as needed. 
Other secondary exploratory endpoint for the cohorts 1-3 and 5 will focus on the ability of biochemical changes in the DNA damage 
repair and cell cycle checkpoint pathways to be associated with response. This will be evaluated in a descriptive fashion. For cohort 5, 
all participants will undergo a biopsy at baseline. It is expected that 12 participants may be clinical responders and that perhaps 6 to 12 
more may have clinical benefit. Beginning at the first time after which a tumor grows >15% over baseline, among those who have 
responded or shown clinical benefit by 4 months, a second biopsy at progression will be obtained to provide potential resistance 
mechanisms. For a potential single protein or gene biomarker, with 16 paired biopsies available, there would be 80% power to detect a 
change from baseline with an effect size of 0.75 (0.75 SD of the change) which would be significant at the 0.05 two-tailed significance 
level using a paired t-test. Similarly, 15 paired biopsies would result in 94% power to detect a change with a 1.0 SD effect size, while 
10 paired biopsies would have 80% power for a 1.0 SD effect size, both with a 0.05 two-tailed significance level. If there were 3 total 
potential protein or gene biomarkers instead of one, 22 paired biopsies would yield 81% power for a 0.75 SD effect size using a two-
tailed 0.017 significance level paired t-test in order to permit adequate participants for a very strict Bonferroni adjustment, holding the 
three tests to an overall 0.05 significance level, while 14 paired biopsies would have 81% power for detecting a 1.0 SD effect size, 
also at the 0.017 significance level. In practice, a Wilcoxon signed rank test will be used instead of a paired t-test if the changes are not

Amendment Version Date: 12/02/2020
normally distributed (p<0.05 by a Shapiro-Wilks test). Also, if multiple markers are being evaluated, a Hochberg adjustment may be 
used instead of an overly conservative Bonferroni correction.
In the participants enrolled in cohort 6, analyses of biomarkers will be undertaken based on blood samples. As indicated in section 
5.1.4, a variety of molecular markers will be collected and evaluated to determine if there are changes in the values after treatment vs. 
at baseline. For each of the parameters mentioned in section 5.1.4 (CTCs, immune subsets such as Tregs, MDSC, CD8 T+ cells, PD-1, 
TIM3, CTLA-4, and/or CD40, and γH2AX and MRE11), values will be obtained at baseline and at C1D15. The change in values 
between the two timepoints will be determined and assessed for statistical significance in an exploratory fashion. If there are 30 
participants with paired values, for a given biomarker, there would be 90% power to detect a difference from baseline with an effect 
size of 0.75 (0.75 SD of the difference), with a 0.01 two-sided significance level, using a paired t-test. In practice, a Wilcoxon signed 
rank test will be used if the differences are not normally distributed (p<0.05 by a Shapiro-Wilks test). Also, as this will be an 
exploratory analysis, the significance of the changes will be reported without any formal adjustment for multiple comparisons, but in 
the context of the number of tests performed.
 
Several of the molecular markers may also be compared between responders and non-responders in cohort 6 in an exploratory fashion. 
Assuming that 1/3 of the participants are responders and 2/3 are non-responders, and data are available on 30 of the participants in 
cohort 6, with  data on changes from baseline to cycle 1 day 15 from 10 responders and 20 non-responders, for a given parameter, 
there would be 87% power to detect a difference between the two groups with an effect size of 1.25 (1.25 SD of the difference), with a 
0.05 two-sided significance level, using a two-group t-test.  In practice, a Wilcoxon rank sum test will be used if the differences are 
not normally distributed (p<0.05 by a Shapiro-Wilks test). Also, as this will be an exploratory analysis, the significance of the changes 
will be reported without any formal adjustment for multiple comparisons but in the context of the number of tests performed.
It is expected that 35-40 participants per year may enroll onto this trial. In order to have 143 total evaluable participants, it is 
anticipated that 4-4.5 years may be required for accrual. To allow for a small number of non-evaluable participants, the accrual ceiling 
will be set at 153 participants.

11 COLLABORATIVE AGREEMENTS
11.1 COOPERATIVE RESEARCH AND DEVELOPMENT AGREEMENT (CRADA)
11.1.1 Eli Lilly and Company
The investigational study agent, LY2606368, is provided by Eli Lilly and Company under a Collaborative Agreement [Cooperative 
Research and Development Agreement (CRADA #02915)].
12 HUMAN SUBJECTS PROTECTIONS 
12.1 RATIONALE FOR SUBJECT SELECTION
Subjects from all racial/ethnic groups are eligible for this study if they meet the eligibility criteria. To date, there is no information that 
suggests that differences in drug metabolism or disease response would be expected in one group compared to another. Efforts will be 
made to extend accrual to a representative population, but in this preliminary study, a balance must be struck between patient safety 
considerations and limitations on the number of individuals exposed to potentially toxic and/or ineffective treatments on the one hand 
and the need to explore ethnic aspects of clinical research on the other hand. If differences in outcome that correlate to ethnic identity 
are noted, accrual may be expanded or a follow-up study may be written to investigate those differences more fully.  This study will 
be recruited through internal referral, our local physician referral base, and through Cancer Hotline information.
12.2 PARTICIPATION OF CHILDREN
Subjects under 18 are excluded because the incidence of breast or ovarian cancer in this population is extremely rare.  The study 
medication is also investigational and has not been studied in pediatric populations.
12.3 PARTICIPATION OF SUBJECTS UNABLE TO GIVE CONSENT
Adults unable to provide consent are excluded from enrolling in the protocol. However, it is possible that subjects enrolled in the 
protocol may permanently lose the capacity to consent for themselves during the course of this study.  In the event this occurs, the 
subjects will remain in the study because, although the risk of participation is greater than minimal due to the potential toxicities of 
treatment, there is a prospect for direct benefit due to the potential for reduction of tumor burden.  All subjects ≥ age 18 will be 
offered the opportunity to fill in their wishes for research and care, and assign a substitute decision maker on the “NIH Advance 
Directive for Health Care and Medical Research Participation” form so that another person can make decisions about their medical 
care in the event that they become incapacitated or cognitively impaired during the course of the study.

Amendment Version Date: 12/02/2020
Note: The PI or AI will contact the NIH Ability to Consent Assessment Team (ACAT) for evaluation to assess ongoing capacity of the 
subjects and to identify an LAR, as needed.  
Please see section 12.6.1 for consent procedure. 
12.4 EVALUATION OF BENEFITS AND RISKS/DISCOMFORTS
Subjects enrolled on this study may receive direct benefit from participating in this protocol. LY2606368 demonstrated inhibition of 
tumor growth in multiple-tumor xenograft models as a single agent and in combination with gemcitabine. LY2606368, formulated in 
Captisol® for intravenous (IV) administration, appears to have a high volume of distribution, which indicates a wide distribution into 
tissues and organs. The most common SAEs deemed related to LY2606368 treatment were hematologic toxicities or complications 
resulting from neutropenia, leucopenia, or thrombocytopenia.
12.4.1 Risks of Radiation
The study will involve radiation from the following sources:

Up to 3 CT scans for the collection of biopsies

Up to 7 CT scans per year for disease assessment
Subjects in this study may be exposed to approximately 10.1 rem. This amount is more than would be expected from everyday 
background radiation. Being exposed to excess radiation can increase the risk of cancer. The risk of getting cancer from the radiation 
exposure in this study is 1 out of 100 (1%) and of getting a fatal cancer is 0.5 out of 100 (0.5%). 


 71
CC Protocol #: 14-C-0156
Abbreviated Title: LY Chk1/2 Inhibitor 
Amendment Version Date: 12/02/2020
12.4.2 Risk of Treatment:  Details of the risk of drug therapy are detailed in section 13.
12.4.3 Blood draws: Side effects of blood draws include pain and bruising, lightheadedness, and rarely, fainting.
12.4.4 CT scans:  In addition to the radiation risks discussed above, risks associated with CT scans are allergic reaction to and kidney 
damage from the contrast dye, nausea, vomiting, and anxiety.
12.4.5 Biopsies:  The non-radiation risks associated with the biopsy procedure include pain, swelling and/or bleeding at the biopsy 
site; infection; and allergic reaction to the local anesthetic used.  
12.5 RISKS/BENEFITS ANALYSIS
This dose and schedule of 105mg/m2 was selected based on the nonclinical PK/PD model, the clinical PK data demonstrating that the 
LY2606368 systemic exposure at the Maximum Tolerated Dose (MTD) for each schedule of administration is in the range predicted 
for maximal tumor response, the human PD simulations that predict the average %pChk1 inhibition at the MTD for each schedule of 
administration achieves the requirements described for the minimum tumor response, the similar safety profile for each schedule, and 
the increased patient convenience.

Adult subjects: More than minimal risk and the prospect of direct benefit.

Adults unable to consent:  Category B - Research involving greater than minimal risk but presenting the prospect of direct 
benefit to the individual subjects.

Protocol Specific Justification for Risk Assessment: For adults who lose the capacity to consent the risk is greater than 
minimal due to the potential toxicities of treatment, but there is prospect for direct benefit due to the potential for reduction of 
tumor burden.
12.6 CONSENT PROCESS AND DOCUMENTATION
The informed consent document will be provided to the participant or consent designee(s) as applicable for review prior to 
consenting.  A designated study investigator will carefully explain the procedures and tests involved in this study, and the associated 
risks, discomforts and benefits. In order to minimize potential coercion, as much time as is needed to review the document will be 


 72
CC Protocol #: 14-C-0156

Amendment Version Date: 12/02/2020
given, including an opportunity to discuss it with friends, family members and/or other advisors, and to ask questions of any 
designated study investigator. A signed informed consent document will be obtained prior to entry onto the study.
The initial consent process as well as re-consent, when required, may take place in person or remotely (e.g., via telephone or other 
NIH approved remote platforms) per discretion of the designated study investigator and with the agreement of the participant/consent 
designee(s).
Whether in person or remote, the privacy of the subject will be maintained. Consenting investigators (and participant/consent 
designee, when in person) will be located in a private area (e.g., clinic consult room). When consent is conducted remotely, the 
participant/consent designee will be informed of the private nature of the discussion and will be encouraged to relocate to a more 
private setting if needed.  
12.6.1 Consent Process for Adults Who Lack Capacity to Consent to Research Participation
For participants addressed in section 12.3, an LAR will be identified consistent with Policy 403 and informed consent obtained from 
the LAR, as described in Section 12.6.
13 REGULATORY AND OPERATIONAL CONSIDERATIONS

CC Protocol #: 14-C-0156
Abbreviated Title: LY Chk1/2 Inhibitor 
Amendment Version Date: 12/02/2020

Determination of futility
Study may resume once concerns about safety, protocol compliance, and data quality are addressed, and satisfy the sponsor, IRB and 
as applicable, Food and Drug Administration (FDA).
13.2 QUALITY ASSURANCE AND QUALITY CONTROL
Each clinical site will perform internal quality management of study conduct, data and biological specimen collection, documentation 
and completion.  An individualized quality management plan will be developed to describe a site’s quality management.
Quality control (QC) procedures will be implemented beginning with the data entry system and data QC checks that will be run on the 
database will be generated. Any missing data or data anomalies will be communicated to the site(s) for clarification/resolution.
Following written Standard Operating Procedures (SOPs), the monitors will verify that the clinical trial is conducted and data are 
generated and biological specimens are collected, documented (recorded), and reported in compliance with the protocol, International 
Conference on Harmonisation Good Clinical Practice (ICH GCP), and applicable regulatory requirements (e.g., Good Laboratory 
Practices (GLP), Good Manufacturing Practices (GMP)). 
The investigational site will provide direct access to all trial related sites, source data/documents, and reports for the purpose of 
monitoring and auditing by the sponsor, and inspection by local and regulatory authorities.
13.3 CONFLICT OF INTEREST POLICY
The independence of this study from any actual or perceived influence, such as by the pharmaceutical industry, is critical.  Therefore, 
any actual conflict of interest of persons who have a role in the design, conduct, analysis, publication, or any aspect of this trial will be 
disclosed and managed. Furthermore, persons who have a perceived conflict of interest will be required to have such conflicts 
managed in a way that is appropriate to their participation in the design and conduct of this trial.  The study leadership in conjunction 
with the National Cancer Institute has established policies and procedures for all study group members to disclose all conflicts of 
interest and will establish a mechanism for the management of all reported dualities of interest.

Amendment Version Date: 12/02/2020
13.4 CONFIDENTIALITY AND PRIVACY
Participant confidentiality and privacy is strictly held in trust by the participating investigators, their staff, and the sponsor(s). This 
confidentiality is extended to cover testing of biological samples and genetic tests in addition to the clinical information relating to 
participants. Therefore, the study protocol, documentation, data, and all other information generated will be held in strict confidence. 
No information concerning the study or the data will be released to any unauthorized third party without prior written approval of the 
sponsor. 
All research activities will be conducted in as private a setting as possible.
The study monitor, other authorized representatives of the sponsor, representatives of the Institutional Review Board (IRB), and/or 
regulatory agencies may inspect all documents and records required to be maintained by the investigator, including but not limited to, 
medical records (office, clinic, or hospital) and pharmacy records for the participants in this study. The clinical study site will permit 
access to such records.
The study participant’s contact information will be securely stored at the/each clinical site for internal use during the study. At the end 
of the study, all records will continue to be kept in a secure location for as long a period as dictated by the reviewing IRB, Institutional 
policies, or sponsor requirements.
Study participant research data, which is for purposes of statistical analysis and scientific reporting, will be stored at the NCI CCR. 
This will not include the participant’s contact or identifying information. Rather, individual participants and their research data will be 
identified by a unique study identification number. The study data entry and study management systems used by the clinical site and 
by NCI CCR research staff will be secured and password protected. At the end of the study, all study databases will be archived at the 
NIH.
To further protect the privacy of study participants, a Certificate of Confidentiality has been issued by the National Institutes of Health 
(NIH).  This certificate protects identifiable research information from forced disclosure. It allows the investigator and others who 
have access to research records to refuse to disclose identifying information on research participation in any civil, criminal, 
administrative, legislative, or other proceeding, whether at the federal, state, or local level. By protecting researchers and institutions 
from being compelled to disclose information that would identify research participants, Certificates of Confidentiality help achieve the 
research objectives and promote participation in studies by helping assure confidentiality and privacy to participants.

14 PHARMACEUTICAL INFORMATION  
14.1 LY2606368
14.1.1 Source 
LY2606368 is an investigational agent (IND #123172) and will be supplied to the NIH Clinical Center by Eli Lilly and Company 
(Indianapolis, IN).
14.1.2 Toxicity 
As of 04 April 2016, data were available from 210 patients who were treated with LY2606368 on Schedule 1 or 2. PK data are 
available from 194 patients from 3 ongoing clinical trials (studies JTJA, JTJF, and JTJK). Study JTJA is the first-in-human phase 1 
study of LY2606368. 
Hematologic Toxicity
Neutropenia is the most frequent toxicity in study JTJA and has been observed at all doses and schedules of LY2606368. 
Prophylactic granulocyte colony stimulating factor (G-CSF) use is permitted as indicated in 3.3.1.1.  
Non-Hematologic Toxicity
The only non-hematologic treatment-emergent AEs (TEAEs) occurring in greater than 10% of patients and deemed by the 
investigators to be related to LY2606368 treatment (combined Schedule 1 and Schedule 2) were nausea (15%, grade 1: 14%, grade 2: 
1%) and fatigue (29%, grade 1/2: 27%, grade 3: 2%). Related non-hematologic TEAEs occurring in 5% to 10% of patients included: 
anorexia (8%), headache (7%), oral mucositis (7%), diarrhea (5%), and vomiting (5%). All of these were grade 1 or 2. 
Cardiovascular Effects
Please see 3.3.2 QTc Prolongation.
No corrected QT interval (QTc) prolongation was observed in dogs at doses up to 10 mg/kg (200 mg/m2). The mean maximum plasma 
concentration (Cmax) levels at the dose at which QTc prolongation was seen in dogs (6950 and 5862 ng/mL at 40 mg/kg, or 800 


 76
CC Protocol #: 14-C-0156
Abbreviated Title: LY Chk1/2 Inhibitor 
Amendment Version Date: 12/02/2020
mg/m2, given as a 1- or 2-hour infusion, respectively) are significantly greater than the largest mean LY2606368 Cmax in humans at the 
MTD of 40 mg/m2 administered on days 1 to 3 every 14 days (Schedule 1) (cohort mean = 347 ng/mL on day 3 of cycle 1 from Part A 
in the current phase I study [dose escalation]), and the largest mean LY2606368 Cmax in humans at the MTD of 105 mg/m2 
administered on day 1 every 14 days (cohort mean = 867 ng/mL on day 1 of cycle 2 from Part A in the current phase I study).
As of April 2016, in study JTJA (LY2606368 monotherapy), no prolongations in average QTcF interval to >480 ms or of > 60 ms 
from baseline were observed with LY2606368 monotherapy (n=101) at any time point. Eight patients (7.9%) had a QTcF change of > 
30 ms from baseline. None of these changes exceeded 39 ms, and none were observed to be associated with AEs. In study JTJK 
(LY2606368 monotherapy in Japanese patients), two of 10 patients had grade 2 QTcF prolongation (both were on 80mg/m2; one with 
baseline QTcF 468 ms, changed to post-treatment QTcF 511 ms with grade 1 atrial fibrillation, and no known history of 
cardiovascular issues and normal electrolytes, deemed DLT; another with baseline QTcF 432 ms but had nonspecific T wave changes, 
precluding accurate measurement of the QT interval. No other cardiac AEs were reported for these patients. A thorough QTc study has 
not yet been conducted to date for Japanese patients. 
On days when LY2606368 is administered, patients should avoid taking any concomitant medications within 12 hours before and after 
the infusion of LY2606368 that are known or suspected to cause prolonged QTc or Torsades de Points and, if possible, alternative 
agents should be considered.
Because LY2606368 interacts with multiple 5-hydroxytryptamine (5-HT) receptors, patients should be monitored closely for any signs 
and symptoms of serotonin syndrome. If observed, appropriate treatment (eg, cyproheptadine or octreotide) may be used as a 
treatment.
Additional findings in animals that also may occur in humans at clinically relevant doses include abnormal stools, skin reddening, 
decreased body weight and/or food consumption, and tremors.
In addition, 8 of 20 dogs given doses of LY2606368 above the MTD were sacrificed for humane reasons prior to scheduled 
termination. The primary clinical signs associated with the declining condition of these animals were consistent with gastrointestinal 
(GI) injury and dehydration.
Experience with concurrent radiation therapy (RT) and LY2606368
There is an ongoing study with LY2606368 in combination with either cisplatin/RT or cetuximab/RT in patients with locally advanced HNSCC 
(study JTJI). As of August 2017, 19 patients have been dosed at LY2606368 doses of 20 mg/m2 or 40 mg/m2 in combination with IMRT – 2.0 
Gy/day fractions (daily x 5 for 7 weeks)- LY2606368 is still given biweekly. Validated data is available from 14 patients (Study JTJI,  Table 7 and 


 77

Amendment Version Date: 12/02/2020
below).   The toxicities have been consistent with either radiation, LY2606368, or cetuximab/cisplatin.  During palliative radiation, a break in 
LY2606368 therapy is allowed not to overlap the therapies.  Currently, the estimated median terminal half-life of LY2606368 is 27 hours.

14.1.3 Formulation and preparation 
The drug product, LY2606368 for injection, is supplied for clinical trial use as a lyophilized, yellow to white solid, in glass vials and 
is composed of LY2606368 mesylate monohydrate and the inactive ingredient Captisol®.  Each vial contains 20 mg or 40 mg of the 
base compound LY2606368.  The vial contains a 5% excess to facilitate the withdrawal of the label amount, 20 mg/vial or 40 mg/vial 
for application with an appropriate device, such as an infusion set.
LY2606368 will be infused through a low-sorbing, polyolefin-lined administration set with in-line 0.2-micrometer polyethersulfone 
filter.  All components must be DEHP-free.  
Patients will receive LY2606368 at the RP2D of 105 mg/m2 IV once every 14 days of a 28-day  cycle.
Reconstituting the vial contents with 10 mL of water gives a clear yellow solution with a concentration of 2 mg/mL of LY2606368, 
pH 4 to 7, and an osmotic pressure ratio of 344 mOsm.

Abbreviated Title: LY Chk1/2 Inhibitor 
Amendment Version Date: 12/02/2020
14.1.4 Stability and Storage 
The drug product is stable when stored at room temperature.
The reconstituted formulation is stable for at least 24 hours at room temperature; however, since the reconstituted drug product does 
not contain a preservative, the unused solution must be discarded after 12 hours.
14.1.5 Administration procedures 
LY2606368 dose MAY be recalculated during repeated treatment cycles as a function of minor changes in body weight measurements 
through time.  Dose recalculation during repeated treatment cycles is REQUIRED only when a patient's weight changes +/- 10% or 
more from their body weight measured just before starting study treatment (baseline weight).
LY2606368 is administered as an IV infusion over 1hour (+/-10min) using a central or free flowing peripheral IV line with an 
appropriate filter. Subsequent infusion may be extended if infusion over 1hr was not well tolerated, including but not limited to grade 
1 facial flushing. LY2606368 should not come in contact with normal saline.  The patient’s vascular access device should be flushed 
with dextrose 5% injection (D5W) before and after LY2606368 administration.
The reconstituted drug product from the vials should be diluted with Dextrose 5% Injection (D5W) to a final volume of no more than 
250 ml. If less than 250 ml is used, the concentration of LY2606368 must be maintained within a range of 0.08 mg/mL to 1.60 mg/mL 
of LY2606368.
14.1.6 Incompatibilities  
LY2606368 is incompatible with solutions containing saline or lactated Ringer and must not be mixed or administered simultaneously 
with other drugs through the same infusion line.

16.3 APPENDIX C – LABORATORY STANDARD OPERATING PROCEDURE- TISSUE CORE COLLECTION
Lee Laboratory Standard Operating Procedure for Tissue Core Collection- 
Needle Biopsy – Cryopreservation in OCT 
Principle: 
Core needle biopsies are used to sample tissue from a specific, defined location. These biopsies may consist of normal, pre-malignant 
and malignant tissue due to the multi-level tissue sample that is obtained. This type of sample is ideal for studying the micro-tumor 
environment. 
Rapid freezing of the sample is required to prevent degradation of the proteins or RNA. Optimal Cutting Temperature (OCT) 
compound is an alcohol polymer that is liquid at room temperature and a solid at –20oC. This polymer is used to cryo-protect the 
tissue and provide a medium for cryo-sectioning. 
Materials: 
Cryomolds (Sakura Finetek Ca.t # 4728) 
OCT (Sakura Finetek Cat. # 4583) 
Dry ice 
Ultra cold freezer (-700 to -800C) 
Needle: 16 or 18 gauge 
Permanent marker 
Sterile forceps 
Sterile Glass slides 
Aluminum foil or 50ml Falcon tubes 
Procedure: 
1. Prepare all supplies prior to the biopsy procedure to avoid delay once the specimen has been obtained. 
2. Label the handle and the front surface of the cryomold with the sample or participant’s identifying information. 
3. Perform core needle biopsy. 
4. Pick the core from the biopsy needle onto a sterile glass slide. 
5. Fill cryomold about 1/3 full with OCT. Place the cryomold in dry ice to partially freeze the OCT. The OCT should be jelly-like, not 
completely frozen. 
6. Carefully lift the core biopsy by both ends with sterile forceps. Do not stretch the biopsy or it will break. 


 90
CC Protocol #: 14-C-0156
Abbreviated Title: LY Chk1/2 Inhibitor 
Amendment Version Date: 12/02/2020
7. Lay the biopsy as straight as possible in the OCT. Once the sample touches the OCT, you cannot reposition it or the sample will 
break apart. 
8. Quickly add OCT on top of the biopsy, completely covering the sample. 
9. Ensure the sample is level and freeze immediately in dry ice. 
10. Store wrapped in aluminum foil or in a 50ml Falcon tube at –70oC. 
Note:
Do not lay the biopsy on frozen OCT and cover it with liquid OCT. The OCT will not fuse and will split into two sections when 
cutting the frozen tissue sections.
Frozen Section Slides
1. Frozen sections for proteomic analysis should be cut at 5-8um on plain, uncoated glass microscope slides.
2. The tissue section should be placed as close as possible to the center of the slide. Do not place the frozen section at the end of the 
slide.
3. Two tissue sections from the same biopsy may be placed on the same glass slide if space permits.
4. Do not allow the tissue section to air on the slide. Freeze immediately on dry ice or at –80oC.

INTRODUCTION 
We invite you to take part in a research study at the National Institutes of Health (NIH). 
First, we want you to know that: 
Taking part in NIH research is entirely voluntary.  
You may choose not to take part, or you may withdraw from the study at any time.  In 
either case, you will not lose any benefits to which you are otherwise entitled.  However, 
to receive care at the NIH, you must be taking part in a study or be under evaluation for 
study participation. 
You may receive no benefit from taking part.  The research may give us knowledge that 
may help people in the future. 
Second, some people have personal, religious or ethical beliefs that may limit the kinds of medical 
or research treatments they would want to receive (such as blood transfusions).  If you have such 
beliefs, please discuss them with your NIH doctors or research team before you agree to the study. 
Now we will describe this research study.  Before you decide to take part, please take as much 
time as you need to ask any questions and discuss this study with anyone at NIH, or with family, 
friends or your personal physician or other health professional.   
Why is this study being done?  
The main purpose of this study is to see whether an investigational drug, LY2606368, will help to 
shrink tumors in people with certain types of breast and ovarian cancer.  LY2606368 is 
manufactured by Eli Lilly and is not approved by the United States (U.S.) Food and Drug 
Administration (FDA) to treat any type of breast or ovarian cancer, or any other type of disease.  
All cells go through cycles which allow them to divide. Cell division is important because it allows 
all living things to grow, to heal and to reproduce. In normal cells, there are many proteins which 
help to make sure that cells are dividing correctly.  LY2606368 blocks two of these proteins called 
Chk1 and Chk2.  In normal cells, Chk1/2 stop cell division at various points to allow any damage

to DNA to be repaired and to make sure that chromosomes are lined up correctly.  When Chk1/2 
are not present, cells stop dividing and eventually die.  The researchers in this study hope that by 
blocking these proteins it will cause tumor cells to die, thereby shrinking tumors. 
Why are you being asked to take part in this study? 
You are being asked to participate in this study because you have been diagnosed with: 
1) Breast or ovarian cancer and have a mutation in BRCA1/2 genes (BRCAm) 
2) High Grade Serious Ovarian Cancer (HGSOC) OR 
3) Triple Negative Breast Cancer (TNBC) OR 
4) Recurrent platinum-resistant High Grade Serious Ovarian Cancer (HGSOC) AND 
5) All other standard measures have failed to cure your cancer. 
How many people will take part in this study? 
About 153 people will take part in this research study.  
Description of Research Study 
What will happen if you take part in this research study?   
This study consists of the following parts: 
 
A screening period that may last up to 30 days, during which tests will be done to see 
if you qualify to take part in the study. 
 
A treatment period consists of 28 day cycles during which you will be given study 
drug once every 14 days (day 1 and day 15 of every cycle).  This treatment period 
will continue until up to 2 cycles after your cancer goes away, until your cancer gets 
worse, or if you are withdrawn from the study.  If you cannot tolerate LY2606368, it 
may also be necessary to end your treatment. 
 
An end of treatment visit (for safety reasons) will be done after the last dose of study 
drug. 
 
If your cancer completely goes away, you will be followed every 4 weeks with non-
invasive imaging performed every 12 weeks until your cancer returns, gets worse, or 
if you are withdrawn from the study.    
Before you begin the study 
Certain standards (criteria) have been established to ensure that you are a medically appropriate 
candidate for this trial. These criteria also make sure that the results of this study can be used to 
help make decisions about treating other patients. We will record your medical history and give 
you a physical examination. We will review slides of a previous biopsy you have had to confirm 
your diagnosis. You will undergo standard blood tests including a complete blood count, chemistry

panel, a pregnancy test, an EKG, and scans and x-rays as part of the NCI Screening Protocol. One 
test of your immune system will be a blood test that checks for the presence of the human 
immunodeficiency virus (HIV), the cause of acquired immunodeficiency syndrome (AIDS). HIV 
infection may disqualify you from this study. If you test positive for HIV, we will tell you what 
the results mean, how to find care, how to avoid infecting others, and how we report newly 
diagnosed HIV infection. 
If you are eligible to participate in this trial and wish to do so, a CT-assisted biopsy of your tumor 
will be performed for research purposes before you start treatment. If you are in the one of groups 
1-3, an additional CT-assisted biopsy may be performed during Cycle 1 if you agree, after your 
dose of study drug on Day 15 and at the end of your study treatment. If you are in group 5 and 
respond to the treatment longer than 4 months, an additional CT-assisted biopsy will be performed 
when your tumor stops shrinking so that researchers can study what made the tumors stop 
responding to LY2606368. If you are in group 6, you will not have an additional CT-assited biopsy. 
During the study 
During the study, the study doctor and staff will monitor you for any side effects and monitor your 
cancer.  You may receive supportive care during this study.  Ask the study doctor or staff if you 
have questions about supportive care.  During Cycle 1, you will receive weekly phone calls to ask 
about whether there have been any changes to your health and about any other medications that 
you may be taking.  For safety, during Cycle 1, you will also have routine laboratory tests done 
weekly, then every other week for Cycle 2 and beyond.  About 3 tablespoons of blood will be 
drawn for these tests.   
Day 1 
After all of your baseline tests are complete, you will start treatment.  On Day1, the study staff 
will perform a complete physical exam.  They will ask if there have been any changes to your 
physical health and about any medications you have taken since your screening visit.  They will 
check your vital signs and may do some routine laboratory tests.  Laboratory tests that were 
completed within the last 3 days before Cycle 1 Day 1, will not be repeated. Blood will also be 
drawn for research tests to assess certain cancer markers (about 2 tablespoons).  A CT scan of the 
chest, abdomen, and pelvis will not be repeated if you had one done within 14 days prior to the 
start of Cycle 1 Day 1. 
LY260368 Therapy 
You will receive the study drug LY260368 through an infusion in your vein over approximately 
one hour on Day 1 and on Day 15 of each 28-day cycle. 
Therapy will be continued every 14 days until your cancer goes away, until your cancer gets worse, 
or until you are withdrawn from the study. 
Your vital signs will be assessed 30 minutes before and after you have received the study drug. 
An EKG will be done within 1 hour after you have received the study drug.

Day 15 
On Day 15, you will be asked about whether there have any been any changes to your physical 
health and about any medications you have taken.  The study staff will perform a complete physical 
examination and you will have some routine laboratory tests done for safety.  About 3 tablespoons 
of blood will be drawn for these tests.  If you are in the one of groups 1-3, you will be asked if you 
want to have a second biopsy.  This second biopsy, which would be assisted by a CT scan, is for 
research purposes and it is optional. Even if you do not want to do this second biopsy, you can still 
continue on the study.  You will also be required to have an EKG and about 2 tablespoons of blood 
will be drawn to assess certain cancer markers.  
Day 28  
On Day 28, the first treatment cycle will end.  You will be asked about whether there have been 
any changes to your health and about any other medications you have taken.  You will have a 
complete physical exam and have about 3 tablespoons of blood drawn for routine laboratory tests. 
You will also be required to have an EKG. 
Cycle 2 and beyond 
Some tests will be performed every cycle, some will be performed every other cycle, some will be 
performed every three cycles, and some will be completed in the first cycle only.  If you are in the 
group 5 and on the treatment longer than 4 months, you will be asked about a second biopsy when 
your tumors start growing on imaging. This second biopsy, which would be assisted by a CT scan, 
is for research purposes and it is mandatory for the researchers to study what makes tumors become 
resistance to the treatment. This mandatory second biopsy will not be done if you (group 5) don’t 
respond to the therapy longer than 4 months. The Study Chart below gives more information about 
the timing of all of the tests needed for this study.  
When you are finished taking the drugs (treatment) 
If you or your study doctor decides to stop study treatment, if your cancer has spread, or if you 
cannot tolerate the study treatment then you will be asked to return for an end of treatment visit. 
During this visit, the following will be performed: 
 You will have a complete physical examination to assess any changes since the last study 
visit. 
 Your vital signs will be measured. 
 You will be asked if you want to have another CT-assisted biopsy.  It will be your choice 
whether you want to have this biopsy done. 
 Your cancer will be evaluated through CT scans or MRI of the chest, pelvis, and abdomen. 
Male participants may also be evaluated with bone scans. Your tumor will be checked to 
see if it has grown, shrunk or stayed the same.

Birth Control 
If you are a woman who is breast feeding or pregnant, you may not take part in the study because 
we don’t know how this medicine would affect your baby or your unborn child. All participants 
of reproductive capability must agree to use both a barrier method and a second method of birth 
control during the study and for four months after you finish study treatment.  If you are a man 
who is sexually active, you and your female partner must agree to use medically accepted barrier 
methods of contraception (e.g., male or female condom) during the study and for 4 months after 
you finish the study treatment, even if oral contraceptives are also used.  If you think that you, or 
your female partner if you’re a man, are pregnant, you should tell your study doctor or nurse at 
once.   
Effective forms of birth control include:  
• 
abstinence  
• 
intrauterine device (IUD) 
• 
hormonal [birth control pills, injections, or implants]

What tests will be done on my samples? 
 
In addition to the tests that we will conduct to determine whether you are having side effects or if 
you are responding to the study therapy, we will also collect samples from you for purposes of 
research only.  All of your samples collected for research purposes on this study (such as the tumor 
and normal tissue) may be used to look for specific changes in the DNA in tumors that could be 
used to develop new ways of diagnosing and treating cancer. DNA (also called deoxyribonucleic 
acid) in the cells carries genetic information and passes it from one generation of cells to the next 
– like an instruction manual. Normal tissue contains the DNA (instructions) that you were born 
with, DNA in tumor cells has changed – or mutated – and we think that change in the DNA is what 
causes tumors to form and to grow.  
To look at your DNA, we may do what is called “whole genome sequencing.”  This is where we 
will do special tests in the lab to look at the entire sequence, or order, of how your DNA is put 
together.  This is what makes you unique.   
To determine which parts of the DNA have mutated, we will compare the DNA in your tumor cells 
to DNA from your normal cells. We will then analyze the results from similar tumors to see if 
there are any changes in the DNA that are common to a particular type of tumor. To examine the 
tumor and normal tissue we may use several different techniques depending on the type of tissue 
we collect. These could include growing cell lines (cells which keep dividing and growing in the 
laboratory, sometimes for years allowing us to continually study those cells), xenograft studies 
(placing or growing cells in another animal, such as mice), and looking in detail at the parts of the 
genes that produce specific proteins. 
However, you should know that the analyses that we perform in our laboratory are for research 
purposes only; they are not nearly as sensitive as the tests that are performed in a laboratory that 
is certified to perform genetic testing or testing for routine clinical care. For these reasons, we will 
not give you the results of the research tests done on your research samples in most cases.  There 
may be exceptions to what we share with you.  
In the unlikely event that we discover a finding that is believed to be clinically important based on 
medical standards at the time that we first analyze your results, we will contact you.  This could 
be many years in the future. We will ask you to have an additional tube of blood drawn to verify 
the findings we have seen in our lab. If the results are verified, you will be re-contacted and offered 
a referral to a genetic healthcare provider to discuss the results. In the event that you are removed 
from this study before such findings become available, you must be enrolled on a follow-up study 
in order for us to contact you.  This will enable us to maintain updated contact information for you 
and contact you when such findings become available.

Psychological or Social Risks Associated with Loss of Privacy  
The following general points are indirectly related to your participation in the research study: 
1. Unanticipated medical information: During the course of this investigation, it is possible 
(although not likely) that we will obtain unanticipated information about your health or 
genetic background. 
2. Release of genetic information 
 Your privacy is very important to us and we will use many safety measures to protect 
your privacy. However, in spite of all of the safety measures that we will use, we cannot 
guarantee that your identity will never become known. Although your genetic 
information is unique to you, you do share some genetic information with your children, 
parents, brothers, sisters, and other blood relatives. Consequently, it may be possible that 
genetic information from them could be used to help identify you. Similarly, it may be 
possible that genetic information from you could be used to help identify them.  
 Patterns of genetic variation also can be used by law enforcement agencies to identify a 
person or his/her blood relatives. Therefore, your genetic information potentially could be 
used in ways that could cause you or your family distress, such as by revealing that you 
(or a blood relative) carry a genetic disease. 
 There also may be other privacy risks that we have not foreseen. 
 
Since some genetic variations can help to predict future health problems for you and your 
relatives, this information might be of interest to health care providers, life insurance companies, 
and others. However, Federal and State laws provide some protections against discrimination 
based on genetic information. For example, the Genetic Information Nondiscrimination Act 
(GINA) makes it illegal for health insurance companies, group health plans, and most employers 
to discriminate against you based on your genetic information. However, GINA does not prevent 
companies that sell life insurance, disability insurance, or long-term care insurance from using 
genetic information as a reason to deny coverage or set premiums.  GINA also does not apply to 
members of the United States military, individuals covered by the Indian Health Service, or 
veterans obtaining health care through the Veteran’s Administration. Lastly, GINA does not 
forbid insurance medical underwriting based on your current health status though the Affordable 
Care Act limits consideration of pre-existing conditions by insurers.  
 
Who else besides the investigators on this study will know the results of my sample testing? 
Once we obtain any of the samples listed above, the investigators take all your personal 
information off those samples and label them with a study code number.  Only the investigators 
on this study know who the sample came from.  The key linking your personal information with 
the code number is kept in a secure computer data base, with access only to the 2-3 research staff 
who will be discussing this study with you.  Once the sample has been labeled with a code, it is

sent to a variety of NIH laboratories for storage and testing.  No one testing your samples will be 
able to link the results to you personally.  Specimens obtained during your participation in this 
study may be sent for testing to investigators outside of NCI or the NIH.  All samples will be coded 
to protect your privacy and no personal information will be included.  Other investigators on this 
study will have access to limited clinical and biologic data such as age, gender and disease status. 
How long will your samples be stored? 
The samples collected during this study will be stored for as long as the study is open.  When this 
study is closed, we would like to keep the samples for future research.  We will request your 
permission to do so, later in this consent. 
 
Risks or Discomforts of Participation 
What side effects or risks can I expect from being in this study? 
LY2606368 
As with all treatments, there are several side effects or risks from the treatment provided in this 
study. However, doctors don’t know all the side effects that may happen with this drug, so it is 
important to report any changes that you notice, even if your study team does not ask specifically 
about them. Side effects may be mild or severe. Your study team will give you medicines to help 
lessen side effects. Many side effects go away with those medicines and others may go away soon 
after you stop treatment. In some cases, side effects can be serious, long-lasting, or may never go 
away. In very rare instances, they could cause death. 
Just over 100 people have been treated with this study drug.  Based on what these people reported 
the possible side effects are described below:  
Likely 
 Low white blood cell count (which can increase your risk for infections) 
 Low red blood cell count 
 Low platelet count (increases your risk of bleeding) 
 Nausea 
 Fatigue (feeling tired) 
 
Less Likely 
 Vomiting 
 Sore mouth 
 Blood in stool

 Jaundice (yellowing of the skin) 
 Skin infections 
 Urinary tract infection 
 Fainting 
 Nose bleed 
Rare but Serious 
 Pneumonia 
 
Serotonin Syndrome 
There is a potential risk of a condition called serotonin syndrome for patients who use certain 
medications from a class of drugs known as selective serotonin reuptake inhibitors (SSRIs) at the 
same time they’re taking the study drug LY2606368. Serotonin syndrome is a potentially life 
threatening drug reaction that causes the body to have too much serotonin, a chemical produced 
by nerve cells.  Symptoms may include, but are not limited to, agitation or restlessness, severe 
diarrhea, a fast heartbeat, and high blood pressure.  Patients who use SSRIs will be closely 
monitored by their study doctor for any signs and symptoms of serotonin syndrome, and they 
should also be monitored for this condition by their home physician.  Treatment and supportive 
care measures are available to manage serotonin syndrome. 
 
QTc prolongation 
There is a potential risk of developing irregular heartbeats on EKG, a condition called QTc 
prolongation, for patients who are taking the study drug LY2606368. This EKG change is a 
potentially life threatening event. People who have QTc prolongation on EKG are at risk of fainting 
and sudden death. Electrolytes abnormalities increase the risk for developing this change on EKG. 
Your electrolytes and EKG will be closely monitored before and after the study drug LY2606368 
during the first two months, and then every 3 months until the end of treatment. Treatment and 
supportive care measures are available to manage QTc prolongation.

Tumor Biopsy 
If your doctor determines it is safe we will obtain a piece of your tumor (biopsy) using a needle 
with minimal risk to you.  You will be given local anesthesia (numbing medicine) and a sedative 
prior to the biopsy.  The biopsy will be taken through a needle put through the skin into your tumor.  
Depending upon the location of your tumor, a CT scan may be used to assist the biopsy. After the 
procedure the nurses will watch your blood pressure and other vital signs.  This biopsy is not 
optional and you cannot participate in this study if you do not agree to the biopsy. If the first biopsy 
is too difficult or if you experience too much discomfort as a result of it you will be able to continue 
on the protocol without undergoing the second and third biopsies, which are optional. However, 
an attempt at the first biopsy is needed to enter this study. There are other studies at NIH which 
may also be options for you and which do not involve biopsies. 
For group 5, the second biopsy at progression is mandatory for those who responded to 
LY2606368 longer than 4 months.  
 
Risk of Radiation 
This research study involves exposure to radiation from up to 3 CT scans that may be used during 
your tumor biopsies.  This radiation exposure is not required for your medical care and is for 
research purposes only. The amount of radiation you will receive in this study is 2.4 rem which is 
below the guideline of 5 rem per year allowed for research subjects by the NIH Radiation Safety 
Committee.  The average person in the United States receives a radiation exposure of 0.3 rem per 
year from natural sources, such as the sun, outer space, and the earth's air and soil.  If you would 
like more information about radiation, please ask the investigator for a copy of the pamphlet, An 
Introduction to Radiation for NIH Research Subjects.  While there is no direct evidence that the 
amount of exposure received from participating in this study is harmful, there is indirect evidence 
it may not be completely safe.  There may be a very slight increase in the risk of cancer. 
 
Please tell your doctor if you have had any radiation exposure in the past year, either from other 
research studies or from medical tests or care, so we can make sure that you will not receive too 
much radiation. Radiation exposure includes x-rays taken in radiology departments, cardiac 
catheterization, and fluoroscopy as well as nuclear medicine scans in which radioactive materials 
were injected into your body.  
If you are pregnant you will not be permitted to participate in this research study. It is best to avoid 
radiation exposure to unborn infants since they are more sensitive to radiation than adults. 
Blood Sampling  
Risks of blood sampling include bruising or bleeding at the needle site; rarely infection. This is 
treated with bandages, pressure and, if infection, antibiotic medicines. For more information about 
risks and side effects, ask your study team.

Potential Benefits of Participation 
Are there benefits to taking part in this study?  
The aim of this study is to see if this LY2606368 will cause your tumors to shrink.  We do not 
know if you will receive personal, medical benefit from taking part in this study. These potential 
benefits could include shrinking of your tumor or lessening of your symptoms, such as pain, that 
are caused by the cancer.  Because there is not much information about the drug’s effect on your 
cancer, we do not know if you will benefit from taking part in this study, although the knowledge 
gained from this study may help others in the future who have cancer.   
 
Alternative Approaches or Treatments 
What other choices do I have if I do not take part in this study?  
 
Instead of being in this study, you have these options: 
 Getting treatment or care for your cancer without being in a study 
 Taking part in another study 
 Getting comfort care, also called palliative care.  This type of care helps reduce pain, 
tiredness, appetite problems and other problems caused by the cancer.  It does not treat the 
cancer directly.  Instead, it tries to improve how you feel.  Comfort care tries to keep you 
as active and comfortable as possible. 
Please talk to your doctor about these and other options.  
 
Stopping Therapy  
 
Your doctor may decide to stop your therapy for the following reasons: 
 if he/she believes that it is in your best interest 
 if your disease comes back during treatment 
 if you have side effects from the treatment that your doctor thinks are too severe 
 if new information shows that another treatment would be better for you 
 If the study drug is no longer available 
 
In this case, you will be informed of the reason therapy is being stopped. 
You can stop taking part in the study at any time. However, if you decide to stop taking part in the 
study, we would like you to talk to the study doctor and your regular doctor first. 
If you decide at any time to withdraw your consent to participate in the trial, we will not collect 
any additional medical information about you. However, according to FDA guidelines,

information collected on you up to that point may still be provided to Eli Lilly or designated 
representatives. If you withdraw your consent and leave the trial, any samples of yours that have 
been obtained for the study and stored at the NCI can be destroyed upon request. However, any 
samples and data generated from the samples that have already been distributed to other 
researchers or placed in the research databases cannot be recalled and destroyed. 
 
Research Subject’s Rights 
What are the costs of taking part in this study?  
If you choose to take part in the study, the following will apply, in keeping with the NIH policy: 
 
You will receive study treatment at no charge to you. This may include surgery, 
medicines, laboratory testing, x-rays or scans done at the Clinical Center, National 
Institutes of Health (NIH), or arranged for you by the research team to be done outside 
the Clinical Center, NIH if the study related treatment is not available at the NIH.

Certificate of Confidentiality  
To help us protect your privacy, we have obtained a Certificate of Confidentiality. The researchers 
can use this Certificate to legally refuse to disclose information that may identify you in any 
federal, state, or local civil, criminal, administrative, legislative, or other proceedings, for example, 
if there is a court subpoena. The researchers will use the Certificate to resist any demands for 
information that would identify you, except as explained below. 
 
You should also know that there are several circumstances in which the Certificate does not 
provide coverage. These include when information:  
 will be used for auditing or program evaluation internally by the NIH; or  
 must be disclosed to meet the legal requirements of the federal Food and Drug 
Administration (FDA).  
 is necessary for your medical treatment and you have consented to this disclosure;  
 is for other research.  
In addition, identifiable, sensitive information protected by this Certificate cannot be admissible 
as evidence or used for any purpose in any action, suit, or proceeding without your consent.  
You should understand that a Certificate of Confidentiality does not prevent you or a member of 
your family from voluntarily releasing information about yourself or your involvement in this 
research. If an insurer, employer, or other person obtains your written consent to receive research 
information, then the researchers will not use the Certificate to withhold that information. 
The Certificate of Confidentiality will not protect against the required reporting by hospital staff 
of information on suspected child abuse, reportable communicable diseases, and/or possible threat 
of harm to self or others. 
 
Conflict of Interest 
 
The National Institutes of Health (NIH) reviews NIH staff researchers at least yearly for conflicts 
of interest.  This process is detailed in a Protocol Review Guide. You may ask your research 
team for a copy of the Protocol Review Guide or for more information.  Members of the research 
team who do not work for NIH are expected to follow these guidelines but they do not need to 
report their personal finances to the NIH. 
 
Members of the research team working on this study may have up to $15,000 of stock in the 
companies that make products used in this study.  This is allowed under federal rules and is not a 
conflict of interest.

The National Institutes of Health and the research team for this study are using LY2606368 
developed by Eli Lilly through a joint study with your researchers and the company.  The 
company also provides financial support for this study.   
 
Use of Specimens and Data for Future Research 
 
To advance science, it is helpful for researchers to share information they get from studying 
human samples.  They do this by putting it into one or more scientific databases, where it is 
stored along with information from other studies. A researcher who wants to study the 
information must apply to the database and be approved.  Researchers use specimens and data 
stored in scientific databases to advance science and learn about health and disease.   
 
We plan to keep some of your specimens and data that we collect and use them for future 
research and share them with other researchers. We will not contact you to ask about each of 
these future uses.  These specimens and data will be stripped of identifiers such as name, address 
or account number, so that it may be used for future research on any topic and shared broadly for 
research purposes.  Your specimens and data will be used for research purposes only and will not 
benefit you.  It is also possible that the stored specimens and data may never be used.  Results of 
research done on your specimens and data will not be available to you or your doctor.  It might 
help people who have cancer and other diseases in the future.   
 
If you do not want your stored specimens and data used for future research, please contact us in 
writing and let us know that you do not want us to use your specimens and/or data.  Then any 
specimens that have not already been used or shared will be destroyed and your data will not be 
used for future research. However, it may not be possible to withdraw or delete materials or data 
once they have been shared with other researchers.

OTHER PERTINENT INFORMATION 
1. 
Confidentiality.  When results of an NIH research study are reported in medical journals 
or at scientific meetings, the people who take part are not named and identified.  In most cases, the 
NIH will not release any information about your research involvement without your written 
permission.  However, if you sign a release of information form, for example, for an insurance 
company, the NIH will give the insurance company information from your medical record.  This 
information might affect (either favorably or unfavorably) the willingness of the insurance 
company to sell you insurance. 
The Federal Privacy Act protects the confidentiality of your NIH medical records.  However, you 
should know that the Act allows release of some information from your medical record without 
your permission, for example, if it is required by the Food and Drug Administration (FDA), 
members of Congress, law enforcement officials, or authorized hospital accreditation 
organizations. 
2. 
Policy Regarding Research-Related Injuries.  The Clinical Center will provide short-
term medical care for any injury resulting from your participation in research here.  In general, no 
long-term medical care or financial compensation for research-related injuries will be provided by 
the National Institutes of Health, the Clinical Center, or the Federal Government.  However, you 
have the right to pursue legal remedy if you believe that your injury justifies such action. 
3. 
Payments.  The amount of payment to research volunteers is guided by the National 
Institutes of Health policies.  In general, patients are not paid for taking part in research studies at 
the National Institutes of Health.  Reimbursement of travel and subsistence will be offered 
consistent with NIH guidelines. 
4. 
Problems or Questions.  If you have any problems or questions about this study, or about 
your rights as a research participant, or about any research-related injury, contact the Principal
