Brief Summary

The purpose of this study is to examine the safety and efficacy of Ruxolitinib in combination with Trastuzumab in treatment of HER2 positive metastatic breast cancer. Ruxolitinib (Jakafi) is an Food and Drug Administration (FDA) approved treatment for myelofibrosis (a disease of the bone marrow), but its safety and efficacy in breast cancer patients is not known. Trastuzumab (Herceptin) is an FDA-approved treatment for HER2 positive breast cancer. The safety and efficacy of both treatments given in combination is not known. It is hypothesized that Ruxolitinib in combination with Trastuzumab will demonstrate efficacy in treating Metastatic HER2 Positive Breast Cancer subjects, and will have a tolerable safety profile in this patient population.

Outcome Measures

Primary Outcomes (2)

• Maximum Tolerated Dose of Ruxolitinib in Combination With Trastuzumab (Phase I)

  The maximum tolerated dose (MTD) combination is defined as the dose combination associated with a target probability of dose limiting toxicity (DLT) of 0.25. A dose-limiting toxicity is defined as the MTD with DLTs defined as any grade 3 non-hematologic toxicities despite maximal supportive care or any grade 4 hematologic toxicity. The MTD will be estimated using the time to event continual reassessment method (TITE-CRM). The TITE-CRM will use an empirical dose-toxicity model, with a sample size of 10. The dose-toxicity model is calibrated such that the method will eventually select a dose that yields between 16% and 34% DLT.

  Up to 15 weeks

• Progression Free Survival (PFS) (Phase II)

  Progression free survival (PFS) will be measured every 3 cycles (9 weeks of treatment +/- 4 days). PFS will be defined as the time from patient registration until objective or disease progression or death from any cause. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1), 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 progression).

  Up to 24 weeks

Secondary Outcomes (3)

• Objective Response Rate (Phase II)

  Up to 24 weeks

• Number of Participants With Adverse Events (Phase II)

  Up to 6 years

• Clinical Benefit Ratio (CBR) (Phase II)

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Subjects must have histologically or cytologically confirmed adenocarcinoma of the breast with locally recurrent or metastatic disease. Locally recurrent disease must not be amenable to any local treatment with curative intent. Metastatic disease must be demonstrated either radiographically or histologically.
• Primary tumors and/or metastatic lesions must demonstrate HER2-neu overexpression, per the 2013 recommendations, i.e. immunohistochemistry (IHC 3+) or amplification by in situ hybridization based on the following:
• Single-probe average HER2 copy number ≥6.0 signals/cell
• Dual-probe HER2/Chromosome 17 centromere (CEP17) ratio ≥2.0 with an average HER2 copy number ≥4.0 signals/cell
• Dual-probe HER2/CEP17 ratio ≥2.0 with an average HER2 copy number \<4.0 signals/cell
• Dual-probe HER2/CEP17 ratio \< 2.0 with an average HER2 copy number \> 6.0 signals/cell
• Patients should have progressed on at least two lines of HER2-directed therapy in the metastatic setting, and prior therapy for metastatic disease should include both pertuzumab and ado-trastuzumab unless contraindicated or declined by the patient.
• There is no upper limit on the number prior therapies
• Patients may have measurable disease only, non-measurable disease only, or both (RECIST 1.1). Concomitant treatment with bone-targeted therapies such as Receptor activator of nuclear factor kappa-B ligand (RANKL) inhibitors or bisphosphonates is allowed. It is anticipated that most patients will have measurable disease, given the behavior of HER2+ metastatic breast cancer.
• Because no dosing or adverse event data are currently available on the use of ruxolitinib in combination with trastuzumab in patients \<18 years of age, children are excluded from this study.
• Women and men of all races and ethnic groups are eligible for this trial.
• Eastern Cooperative Oncology Group (ECOG) performance status 0-2 (Karnofsky equal to or greater than 60)
• Left ventricular ejection fraction greater than or equal to 50 percent by transthoracic echocardiography or multi-gated acquisition scan (MUGA) within 28 days prior to the first dose of the study drug.
• The subject has a baseline corrected QT interval less than or equal to 480ms.
• Patients must have normal organ and marrow function as defined below:

You may not qualify if:

• Patients who have had chemotherapy, hormonal therapy, or radiotherapy within 2 weeks prior to entering the study or those who have not recovered from adverse events due to agents administered more than 2 weeks earlier.
• Patients who are receiving any other investigational agents or have received other investigational agents within 2 weeks or 5 half-lives of the compound or active metabolites, whichever is longer before the first dose of the study treatment.
• Patients who have previously been treated with an interleukin-6 (IL-6), Janus kinase (JAK) or Signal Transducers and Activators of Transcription (STAT) inhibitor for any indication, such as ruxolitinib or tocilizumab.
• The subject has untreated, symptomatic, or progressive brain metastases. History of Central Nervous System (CNS) metastases or cord compression is allowable if patient has been clinically stable for at least 6 weeks since completion of definitive treatment and is off steroids without symptoms for at least 28 days.
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to ruxolitinib or trastuzumab.
• The effects of ruxolitinib on the developing human fetus are unknown. For this reason and because Janus kinase 2 (JAK2) inhibitor agents as well as other therapeutic agents used in this trial are known to be teratogenic, women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation. Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform the principal investigator immediately.
• Patients receiving any medications or substances that are strong inhibitors of cytochrome P450 (CYP450) 3A4 isoenzyme are ineligible. Patients must be off the strong inhibitor for at least 1 week prior to being deemed eligible.
• Patients may not have an uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness that would limit compliance with study requirements.
• Patients must not have clinically significant cardiovascular disease (New York Heart Association Class III or IV heart failure), uncontrolled clinically significant atrial or ventricular cardiac arrhythmias, or any of the following within the past 6 months: myocardial infarction, new evidence of transmural infarction on electrocardiogram (ECG), unstable angina, coronary angioplasty.
• Pregnant women are excluded from this study because ruxolitinib is a Class C agent with the potential for teratogenic or abortifacient effects. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with ruxolitinib, breastfeeding must be discontinued if the mother is treated with ruxolitinib. These potential risks also apply to trastuzumab, which can cause fetal harm when administered to a pregnant woman.
• Active Infections. Patients with known active infections with human immunodeficiency virus (HIV), hepatitis A virus (HAV), hepatitis B (HBV), and hepatitis C virus (HCV) infections will not be considered for this trial. HIV+ patients on combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with ruxolitinib. In addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy. Testing for HIV or hepatitis is not required.
