Trial Information

A Phase II Trial of HKI-272 (Neratinib) for Patients With Human Epidermal Growth Factor Receptor 2 (HER2)-Positive Breast Cancer and Brain Metastases

Subjects will receive neratinib and a drug-dosing calendar for each treatment cycle. This
drug is given orally on a daily basis, continuously. Each treatment cycle will last for 4
weeks during which time the subject will be taking neratinib every day.

- Physical Exams and vital signs: At the start of each cycle, you will have a physical
exam. You will be asked questions about your general health and specific questions
about any problems that you might be having and any medications you may be taking. You
will also have a neurological examination to assess for neurological symptoms.

- Scans (or Imaging tests): We will assess your tumor by brain MRI every other cycle (the
end of cycles 2, 4, 6, 8, etc.) while on study. CT or MRI scans of your chest,
abdomen, and pelvis will be performed every other cycle, at the same time points as the
brain MRI. Your research doctor may ask you to have a bone scan at the same time points
if this is clinically indicated.

- Photographs: Photographs may be taken of your tumor to assess the response of your
tumor to the treatment. Care will be taken to ensure these do not reveal your identity.

- MUGA or Echo: You will have a MUGA or ECHO done every 3 treatment cycles (the end of
cycles 3, 6, 9, etc.).

- Blood tests: You will have blood tests done at the beginning of each treatment cycle to
check your blood cell counts and how well your organs are functioning. In addition to
regular blood tests, we will be collecting 2-3 tablespoons of blood for research prior
to your study treatment start.

- Neurocognitive Function: If you have previously received treatment for cancer that has
spread to your brain (prior to enrollment on this study), you will be asked to take a
battery of tests that assess your cognition (thinking) at the start of the study, after
2 cycles of treatment, and possibly at the end of the study. With these tests, we are
trying to better understand how your previous treatments and ongoing treatments affect
your memory, attention, learning, and other related skills. These tests will be
administered to you by a trained research assistant and may take 30-45 minutes to

- For preoperative patients only: If you are a patient who is planning to have an
operation to remove the cancer in your brain, you will have your surgery between 7-21
days after starting neratinib. These tests will allow us to measure of how much drug
(neratinib) reaches the central nervous system and will help us understand how well
neratinib does this.

- At surgery, a part of your tumor cerebrospinal fluid will be collected to test for
levels of neratinib. For the cerebrospinal fluid collection, this may require a lumbar
puncture just before your surgery begins (spinal tap) if your neurosurgeon feels he/she
cannot collect this fluid easily during your surgery. A lumbar puncture is a test often
used to detect tumor cells in your cerebrospinal fluid. In this case, we will collect
fluid for testing of cancer cells and will also examine the fluid for neratinib
concentrations. This will provide information on how much drug (neratinib) reaches the
central nervous system. There will be a separate consent form for this procedure given
to you by your neurosurgeon (when applicable). This procedure will be done while you
are already under general anesthesia for your surgery. If you have a contraindication
to having this procedure or if you wish to refuse to undergo this procedure, you may do

- You will also have a blood test on day of surgery to test for levels of neratinib

- You will then resume neratinib once you have recovered from your surgery

After the final dose of the study drug:

You will have a follow-up visit one month after coming off study treatment. During that
visit, you will have a physical examination, functional assessment, assessment of any
toxicities and current medications, and a neurological examination. If you continue to have
ongoing toxicity related to your study treatment, we will continue to follow you until this
toxicity resolves. In addition, we will collect about 5-6 tablespoons of blood for research
and to measure if a marker for your particular breast cancer exists.

We would like to keep track of your medical condition for up to two years after you stop the
study treatment. If you are not seen in follow-up at your participating center (where you
enrolled on the study), we would like to follow you by calling you on the telephone or by
sending you a letter once a year to see how you are doing. We may also contact your doctor
once every 6 months to see how you are doing. Keeping in touch with you and checking your
condition every year helps us look at the long-term effects of the research study. If you do
not wish to be contacted after you stop the study treatment, you must notify the research
study staff of your withdrawal of consent for follow-up

Inclusion Criteria:

- Patients (men or women) must have histologically or cytologically confirmed invasive
breast cancer, with metastatic disease. Patients without pathologic or cytologic
confirmation of metastatic disease should have unequivocal evidence of metastasis by
physical exam or radiologic study.

- Invasive primary tumor or metastatic tissue confirmation of HER2-positive status

- Over-expression by immunohistochemistry (IHC) with score of 3+ (in > 30% of invasive
tumor cells) AND/OR HER2 gene amplification (> 6 HER2 gene copies per nucleus or a
FISH ratio [HER2 gene copies to chromosome 17 signals] of ≥ 2.0)

- Note: Patients with a negative or equivocal overall result (FISH ratio of < 2.0 or ≤
6.0 HER2 gene copies per nucleus) and IHC staining scores of 0, 1+, 2+ are not
eligible for enrollment

- No increase in corticosteroid dose in the week prior to baseline brain MRI

- Prior trastuzumab and lapatinib therapy are allowed.

- There is no limit to the number of previous lines of therapy (including chemotherapy,
trastuzumab, and endocrine therapies)

- No prior therapy with neratinib is allowed

- At least 2 weeks washout period post chemotherapy, any prior protocol therapy,
lapatinib, other targeted or biologic therapy, or radiation therapy is required prior
to study entry

- No washout is required for hormonal therapy but concurrent hormonal therapy is not
allowed for patients on study

Patients with progressive disease (Cohort 1):

- For cohort 1, patients must have new or progressive CNS lesions, as assessed by the
patient's treating physician.

- In cohort 1, patients must have measurable CNS disease, defined as at least one
parenchymal brain lesion that can be accurately measured in at least one dimension
with longest dimension ≥10 mm by local radiology review. Note: measurable non-CNS
disease is NOT required for study participation

- It is anticipated that some patients may have multiple progressive CNS lesions, one
or several of which are treated with SRS or surgery with residual untreated lesions
remaining. Such patients are eligible for enrollment on this study providing that at
least one residual (i.e. non-SRS-treated or non-resected) lesion is measurable (≥10

- Patients who have had prior cranial surgery are eligible, provided that there is
evidence of measurable residual or progressive lesions, and at least 2 weeks have
passed since surgery. If a patient has surgical resection followed by WBRT, then
there must be evidence of progressive CNS disease after the completion of WBRT.

- Patients who have had prior WBRT and/or SRS and then whose prior treated lesions have
progressed thereafter are also eligible. In this case, lesions which have been
treated with SRS may be considered as target lesions if there is unequivocal
evidence, in the opinion of the treating physician, of progression.

Patients with with operable disease (Cohort 2):

- In cohort 2, eligible patients will include those who have CNS disease that is
amenable for surgery (typically < 3 brain metastases and with planned resection by
neurosurgery). These patients may include those who have received or not received
previous treatment(s) for their CNS.

- It is anticipated that that patients who have intracranial disease amenable to
surgery will have measurable CNS disease prior to study entry and to resection.
However, this is not an eligibility requirement. Measurable disease is also not
required to continue on protocol subsequent to surgical resection.

- For patients who undergo surgery, postoperative whole brain radiation therapy will
not be allowed while patients are on study (concurrent neratinib and radiation
therapy has not been studied and toxicity of this is unknown). Patients will require
discontinuation of neratinib if radiation therapy will be administered.

Exclusion Criteria:

- Not pregnant or breastfeeding

- Participants who have had chemotherapy or radiotherapy (including investigational
agents) within 2 weeks prior to entering the study or those who have not recovered
adequately from adverse events due to agents administered more than 4 weeks earlier
(excluding alopecia). Washout from trastuzumab is not required.

- Participants who are currently receiving any other investigational agents

- History of allergic reactions attributed to compounds of similar chemical or biologic
composition to neratinib

- Concurrent use of enzyme-inducing antiepileptic drugs (EIAEDs), including phenytoin,
carbamazepine, oxcarbazepine, fosphenytoin, phenobarbital, pentobarbital, or

- Patients who are receiving any cancer-directed concurrent therapy, such as concurrent
chemotherapy, radiotherapy, or hormonal therapy while on study. Concurrent treatment
with bisphosphonates is allowed but should be started before the first dose of

- Uncontrolled intercurrent illness including, but not limited to ongoing or active
infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac
arrhythmia, or psychiatric illness/social situations that would limit compliance with
study requirements

- More than two seizures over the last 4 weeks prior to study entry

- Patients with known contraindication to MRI, such as cardiac pacemaker, shrapnel, or
ocular foreign body

- Those with leptomeningeal metastases as the only site of CNS disease

- Significant malabsorption syndrome or inability to tolerate oral medications

- Any predisposing chronic condition resulting in baseline grade 2 or higher diarrhea
