About
This phase I trial studies the side effects and the best dose of gamma-secretase inhibitor RO4929097 when given together with paclitaxel and carboplatin in patients with stage II or stage III triple-negative breast cancer. Gamma-secretase inhibitor RO4929097 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs use in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving gamma-secretase inhibitor RO4929097 together with paclitaxel and carboplatin before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed.
Full description
PRIMARY OBJECTIVES:
I. To determine the maximum-tolerated dose (MTD) and dose limiting toxicity (DLT) of RO4929097 (gamma-secretase inhibitor RO4929097) given 3 days on, 4 days off in combination with weekly paclitaxel and every 3 weeks carboplatin that will not cause a 30% or more decrease in paclitaxel area under the plasma-concentration time curve (AUC)0-24hr on day 15 compared to day -1 in patients with clinical stage II-III triple negative breast cancer (TNBC).
SECONDARY OBJECTIVES:
I. To measure real-time pharmacokinetics of RO4929097 when administered in combination with weekly paclitaxel and every 3 weeks carboplatin in patients with stage II-III TNBC.
II. To measure real-time pharmacokinetics of paclitaxel when administered in combination with RO4929097 (3 days on, 4 days off) and every 3 weeks carboplatin in patients with stage II-III TNBC.
III. To evaluate the rate of pathologic and clinical complete response to the treatment with combination of RO492097, paclitaxel, and carboplatin in patients with clinical stage II-III TNBC.
OUTLINE: This is a dose-escalation study of gamma secretase inhibitor RO4929097 (RO4929097).
Patients receive gamma-secretase inhibitor RO4929097 orally (PO) once daily (QD) on days 1-3, 8-10, and 15-17, paclitaxel intravenously (IV) over 60 minutes on days 1, 8, and 15 (day -1 of course one), and carboplatin IV over 60 minutes on day 1. Treatment repeats every 21 days for 6 courses in the absence of disease progression or unacceptable toxicity. Within 4 weeks after completion of neoadjuvant therapy, patients undergo definitive breast surgery.
After completion of study treatment, patients are followed up for 1 year.

The patients must have histologically confirmed breast cancer that is human epidermal growth factor receptor 2 (Her-2) negative (immunohistochemistry [IHC] 0-1+ patients are eligible without fluorescence in situ hybridization [FISH]; IHC2+ patients are eligible with negative FISH; if FISH only is done HER2/chromosome enumeration probe [CEP]17 < 2.0); the invasive tumor must be hormone receptor negative defined as both estrogen receptor and progesterone receptor IHC staining present in less than 10% of invasive cancer cells
-
Eligible patients must have clinical stage II-III breast cancer; patients with inflammatory breast cancer are not eligible
-
Patients must have clinically or radiographically measurable primary breast tumor that measures >= 2.0 cm
-
No prior treatment including radiation therapy, chemotherapy or biotherapy for the currently diagnosed breast cancer is allowed

-
Hemoglobin >= 9 g/dL
-
Leukocytes >= 3,000/mcL

-
Creatinine < 1.5 X institutional upper limit of normal OR creatinine clearance >= 60 mL/min/1.73 m^2 for patients with creatinine levels above institutional normal
-
Women of childbearing potential and men must use two forms of contraception (i.e., barrier contraception and one other method of contraception) at least 4 weeks prior to study entry, for the duration of study participation, and for at least 12 months post-treatment; should a woman become pregnant or suspect she is pregnant while she or her partner are participating in this study and for 12 months after study participation, the patient should inform the treating physician immediately
-
Pregnancy testing; women of childbearing potential are required to have a negative serum pregnancy test (with a sensitivity of at least 25 mIU/mL) within 10-14 days and within 24 hours prior to the first dose of RO4929097 (serum or urine); a pregnancy test (serum or urine) will be administered every 4 weeks if their menstrual cycles are regular or every 2 weeks if their cycles are irregular while on study within the 24-hour period prior to the administration of RO4929097; a positive urine test must be confirmed by a serum pregnancy test; prior to dispensing RO4929097, the investigator must confirm and document the patient's use of two contraceptive methods, dates of negative pregnancy test, and confirm the patient's understanding of the teratogenic potential of RO4929097
-
Female patients of childbearing potential are defined as follows:
- Patients with regular menses
- Patients, after menarche with amenorrhea, irregular cycles, or using a contraceptive method that precludes withdrawal bleeding
- Women who have had tubal ligation

Female patients may be considered to NOT be of childbearing potential for the following reasons:
- The patient has undergone total abdominal hysterectomy with bilateral salpingo-oophorectomy or bilateral oophorectomy
- The patient is medically confirmed to be menopausal (no menstrual period) for 24 consecutive months
-
