Study to Compare Alisertib With Paclitaxel vs. Paclitaxel Alone in Metastatic or Locally Recurrent Breast Cancer

Completed · Phase 2

Conditions studied: Breast Cancer, Breast Carcinoma, Breast Tumors, Malignant Neoplasm of Breast

In brief

The goal of this clinical research study is to learn if the study drug, alisertib (MLN8237), in combination with chemotherapy (paclitaxel), can shrink or slow tumor growth in women with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative or HR-negative, HER2-negative (triple negative) locally recurrent or metastatic breast cancer (MBC). The safety of alisertib in combination with paclitaxel will also be studied. The physical state of the patient, symptoms, changes in the size of the tumor, and laboratory findings obtained while on-study will help the research team decide if alisertib plus paclitaxel is safe and effective in patients with this type of breast cancer. Alisertib belongs to a group of drugs called Aurora kinase inhibitors. Alisertib blocks the activity of Aurora A kinase, a protein that is involved in tumor cell multiplication and survival. Aurora A kinase is expressed at higher than normal levels in many types of cancer, including breast cancer, and preclinical studies suggest that blocking the activity of this protein can lead to the death of cancer cells. Paclitaxel is a chemotherapy drug commonly used to treat many different kinds of cancer, including metastatic breast cancer. The reason to combine alisertib and paclitaxel is that in cancer therapy, combinations of drugs are often more effective as a treatment than either of the same drugs used alone.

Who can join

Age: 18 and older. Sex: female. Healthy volunteers: not accepted.

You may qualify if…

• Voluntary written informed consent before performance of any study-related procedure not part of normal medical care, with the understanding that consent may be withdrawn by the subject at any time without prejudice to future medical care, and signed Health Insurance Portability and Accountability Act (HIPAA) form.
• Female subject (≥18 years old), who is either:
• post-menopausal for at least one year before the screening visit, or
• surgically sterilized, or
• willing to use an acceptable method of birth control (i.e., a hormonal contraceptive, intra-uterine device, diaphragm with spermicide, or condom with spermicide) for the duration of the study.
• Metastatic or locally recurrent breast cancer with histologic confirmation (on either primary or metastatic tumor) of one of the following:
• ER+, HER2- invasive breast cancer (any progesterone receptor [PgR] status)
• Poorly differentiated and/or Grade 3 invasive TNBC, defined as:
• HER2 negative status (based on most recently analyzed biopsy) is defined as immunohistochemistry (IHC) status of 0, 1+ or 2+ (if IHC 2+, a negative FISH test is required, i.e., HER2 fluorescence in situ hybridization (FISH) ratio < 2.0 with an average HER2 copy number <4.0 signals/cell); ER-negative and PR-negative status is defined as ER and PgR <1% nuclei positive by IHC
• Measurable disease by modified Response Evaluation Criteria in Solid Tumors (RECIST) (v1.1) or non-measurable lytic, bone-only disease (mixed blastic/lytic bone disease is allowed); if patient has bone-predominant disease with no measurable disease, there must be a lytic component to the bone metastases that is visible on plain X-ray or CT scan that can be serially followed
• Absolute neutrophil count (ANC) > 1500/mm³, platelets > 100,000/mm³, Hgb > 9 g/dL. Values must be obtained without need for myeloid growth factor or platelet transfusion support within 14 days, however, erythrocyte growth factor is allowed as per published American Society of Clinical Oncology (ASCO) guidelines (available at: http://www.asco.org/quality-guidelines/asco-ash-clinical-practice-guideline-update-use-epoetin-and-darbepoetin-adult).
• Total bilirubin ≤ 1.5 x upper limit of normal (ULN), serum glutamic-oxaloacetic transaminase (SGOT) (AST) and serum glutamic-pyruvic transaminase (SGPT) (ALT) < 2.5 x ULN. AST and/or ALT may be up to 5 x ULN if patient has known liver metastases
• Adequate renal function as defined by: Calculated creatinine clearance must be ≥ 30 mL/minute (see Cockcroft-Gault formula in Appendix 5)
• Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1 (refer to Appendix 4)

You may not qualify if…

• Previous radiation therapy covering the whole pelvis
• Suspected brain metastases, untreated brain metastases or current clinical or radiologic progression of known brain metastases or requirement for steroid therapy for brain metastases
• Patients with treated brain metastases are eligible if they have been stable and off steroids for ≥ 3 weeks
• Prior allogeneic bone marrow or organ transplantation
• Known GI disease or GI procedures that could interfere with the oral absorption or tolerance of alisertib. Examples include, but are not limited to partial gastrectomy, history of small intestine surgery, and celiac disease
• Known history of uncontrolled sleep apnea syndrome and other conditions that could result in excessive daytime sleepiness, such as severe chronic obstructive pulmonary disease; requirement for supplemental oxygen.
• Requirement for administration of proton pump inhibitor, or for constant administration of H2 antagonist, or pancreatic enzymes. Intermittent uses of antacids or H2 antagonists are allowed as described in Section 3.4.
• Systemic infection requiring IV antibiotic therapy within 14 days preceding the first dose of study drug, or other severe infection.
• Myocardial infarction within 6 months prior to enrollment or has New York Heart Association (NYHA) Class III or IV heart failure (see Appendix 3), uncontrolled angina, severe uncontrolled ventricular arrhythmias, or electrocardiographic evidence of acute ischemia or active conduction system abnormalities. Prior to study entry, any ECG abnormality at Screening has to be documented by the investigator as not medically relevant.
• Female subject who is pregnant or breast-feeding. Confirmation that the subject is not pregnant must be established by a negative serum B-human chorionic gonadotropin (B-hCG) pregnancy test result obtained during screening, within 72 hours prior to first dose of study drug(s). Pregnancy testing is not required for post-menopausal or surgically sterilized women.

• Serious medical or psychiatric illness likely to interfere with participation in this clinical study.
• Other severe acute or chronic medical and/or psychiatric condition(s), including but not limited to uncontrolled diabetes, malabsorption, resection of the pancreas or upper small bowel, requirement for pancreatic enzymes, any condition that would modify small bowel absorption of oral medications, or laboratory abnormalities that may increase the risk associated with study participation or investigational product administration or may interfere with the interpretation of study results and, in the judgment of the investigator, would make the patient not eligible for enrollment for this study.
• Diagnosed or treated for another malignancy within 3 years of enrollment, with the exception of complete resection of basal cell carcinoma or squamous cell carcinoma of the skin, or an in situ malignancy, or a stage I cancer with a 5-year Disease Free Survival (DFS) of ≥ 90% (survival rates by stage are available for most cancers on the American Cancer Society website).
