Molecular Profile of Breast Cancer in Ugandan Patients With Stage IIB-III Breast Cancer

Defining the Molecular Profile of Breast Cancer in Uganda and Its Clinical Implications

This phase I trial studies the molecular profile of breast cancer in Ugandan patients with stage IIB-III breast cancer. Creating a molecular profile of breast cancer my help doctors learn more about biological factors associated with breast cancer in Ugandan patients with as well as measure the benefits of locally available diagnostic studies and the possibility of providing treatment via oral medication.

OUTLINE:

SPECIMEN COLLECTION: Patients undergo collection of tumor tissue and peripheral blood samples for analysis via next generation sequencing to identify novel pathways in the pathogenesis of breast cancer.

TREATMENT: Patients are invited to participate in a treatment study. Patients receive cyclophosphamide orally (PO) daily on days 1-21, methotrexate PO QD on days 1, 8, and 15, and capecitabine PO twice daily (BID) on days 1-14. Treatment repeats every 21 days for 8 cycles in the absence of disease progression or unacceptable toxicity.

After completion of study, patients are followed up for 24 months.

Inclusion Criteria:

• Women with any menopausal status, with newly diagnosed, locally advanced and histologically confirmed invasive breast cancer (Patients with stage 2B [i.e. T3N0], 3A, 3B, and 3C disease)
• Absolute neutrophil count (ANC) > 1500/mm
• Hemoglobin > 9 g/dL
• Platelets >=100,000 cells/mm^3
• Total bilirubin =< 1.2 mg/dL
• International normalized ratio (INR) =< 1.5 x upper limit of normal (ULN)
• Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 1.5 x ULN
• Serum alkaline phosphatase should be 1.5 x ULN
• Patients with positive hepatitis B or C serologies without known active disease must meet the eligibility requirements for ALT, AST, total bilirubin, INR, activated partial thromboplastin time (aPTT), and alkaline phosphatase on at least two consecutive occasions, separated by at least 1 week
• Adequate renal function with serum creatinine < 1.5 x ULN
• Premenopausal patients must have a negative serum or urine pregnancy test, including women who have had a tubal ligation and for women less than 12 months after the onset of menopause
• Women of childbearing potential must be willing to use one highly effective form of nonhormonal contraception or two effective forms of nonhormonal contraception by the patient and/or partner and continue its use for the duration of the study treatment
• Left ventricular ejection fraction >= 50%

• Known hypersensitivity to any of the drugs
• Significant current illness (including psychiatric illness)
• Any social situations or other conditions that in the opinion of the investigator limit compliance with study requirements
• Calcium imbalance
• Patients that have received treatment with sorividine or brividine (herpex) or any related analogue within 4 weeks prior to starting the investigational product (IP)
