CRIZENT: Crizotinib and Sunitinib in Metastatic Breast Cancer (CRIZENT)

A Phase IB Study of Crizotinib (XALKORI) and Sunitinib (SUTENT) in Metastatic Breast Cancer

This is a Phase 1 Trial. Crizotinib is a medication that is taken by mouth. It has shown that it can help slow down or stop the growth of tumor cells. The marketing name of the drug is "Xalkori". It has been approved by the FDA (Food and Drug Administration) to treat other types of metastatic cancer, but the investigators believe it may be helpful to treat breast cancer as well.

Sunitinib is the other medication used in the study. It is also taken by mouth in the form of a capsule. The marketing name of this drug is "Sutent". It too has been approved by the FDA to treat other types of cancer, but not for breast cancer.

In this study the investigators will be combining both of these two treatments, but at different doses.

One third of the patients will take Crizotinib 200 mg, twice daily with Sunitinib 25.0 mg once a day.

One third of the patients will take Crizotinib 250 mg, twice daily with Sunitinib 25.0 mg once a day, and One third of the patients will take Crizotinib 250 mg, twice daily with Sunitinib 37.5 mg once a day.

10. Negative pregnancy test (BHCG) within 14 days of study drug initiation for pre- or perimenopausal subjects with an intact uterus.

Exclusion Criteria:

1. Clinically significant gastrointestinal abnormalities that may increase the risk for gastrointestinal bleeding.
2. Clinically significant gastrointestinal abnormalities that may affect absorption of investigational products.
3. Presence of uncontrolled infection.

5. History of any one or more of the following cardiovascular conditions within the past 6 months: - Cardiac angioplasty or stenting - Myocardial infarction - Unstable angina - Coronary artery bypass graft surgery - Symptomatic peripheral vascular disease - Class III or IV congestive heart failure, as defined by the New York Heart Association (NYHA)
6. Poorly controlled hypertension (defined as systolic blood pressure [SBP] of > 150 mmHg or diastolic blood pressure [DBP] of > 90 mmHg).
7. History of cerebrovascular accident including transient ischemic attack (TIA), pulmonary embolism, or untreated deep venous thrombosis (DVT) within the past 6 months. Subjects with recent DVT who have been treated with therapeutic anti-coagulating agents for at least 6 weeks are eligible.
8. Prior major surgery or trauma within 28 days prior to first dose of study drug and/or presence of any non-healing wound, fracture, or ulcer (procedures such as catheter placement not considered to be major).
9. Evidence of active bleeding or bleeding diathesis.
10. Known endobronchial lesions and/or lesions infiltrating major pulmonary vessels
11. Hemoptysis in excess of 2.5 mL (or one half teaspoon) within 8 weeks prior to first dose of study drug.
12. Any serious and/or unstable pre-existing medical, psychiatric, or other condition that could interfere with subject's safety, provision of informed consent, or compliance to study procedures.
13. Patients previously treated with sunitinib or crizotinib.
14. History of other malignancy within the last 5 years, except for carcinoma in situ of the cervix or basal cell carcinoma of the skin.
15. Concurrent use of: - Potent CYP3A4 inhibitors: ketoconazole, itraconazole, clarithromycin, atazanavir, nefazodone, saquinavir, telithromycin, ritonavir, amprenavir, indinavir, nelfinavir, delavirdine and voriconazole. - CYP3A4 inducers: rifampin, rifabutin, rifapentin, phenobarbital, phenytoin, carbamazepine, St. John's Wort, and dexamethasone. Use of dexamethasone for study premedication is allowed. - Grapefruit and grapefruit juice. (Note: Alternative therapies should be used when available. If use of a potent CYP3A4 inhibitor or inducer is necessary, this must be approved by the principal investigator and documented in source documents).
16. History of receiving any investigational treatment within 28 days of study medication initiation.
17. Current severe, uncontrolled systemic disease (e.g., clinically significant cardiovascular, pulmonary, thyroid, or metabolic disease; wound healing disorders; ulcers; or bone fractures).
18. Patients who are pregnant or lactating.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Maximum tolerated dose of the treatment drugs in the patients that are taking it.	To determine the tolerability of the combination of crizotinib and sunitinib in the treatment of women with metastatic breast cancer (MBC). - This is done by identifying the maximum tolerated dose (MTD) for future phase II studies of the combination of crizotinib and sunitinib.	1 year

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Changes that occur in tumor tissue before treatment and after treatment.	Assess the clinical activity of the combination regimen in patients with MBC. - This is done by performing exploratory correlative studies on tissue acquired from accessible metastatic lesions based on serial biopsies performed at baseline and recording changes in biomarker levels between responders vs. non-responders.	2 years
Laboratory results to make sure the treatment is safe.	Safety and toxicity parameters will be summarized using descriptive statistics. All patients who received any amount of study drugs will be included in the safety analysis. Safety analyses will include summaries of adverse event rates (both frequency and incidence tables), baseline laboratory parameters and changes from baseline, frequency of CTCAE toxicity grades for both laboratory and non-laboratory data.	1 year
