About
This phase II trial studies how well FASN inhibitor TVB-2640, paclitaxel, and trastuzumab work in treating patients with HER2 positive breast cancer that has spread to other places in the body (metastatic). FASN inhibitor TVB-2640 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Trastuzumab is a form of targeted therapy because it attaches itself to specific molecules (receptors) on the surface of cancer cells, known as HER2 receptors. When trastuzumab attaches to HER2 receptors, the signals that tell the cells to grow are blocked and the cancer cell may be marked for destruction by the body's immune system. Drugs used in chemotherapy, such as paclitaxel, 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. Estrogen can cause the growth of breast cancer cells. Drugs used in endocrine therapy either lower the amount of estrogen made by the body or blocks the use of estrogen by the tumor cells. This may help stop the growth of tumor cells that need estrogen to grow. Giving FASN inhibitor TVB-2640 and trastuzumab in combination with paclitaxel or endocrine therapy may help control the disease in patients with HER2 positive breast cancer.
Full description
PRIMARY OBJECTIVES:
I. To estimate the overall tumor response rate (ORR i.e. complete response [CR]+partial response [PR]) of the combination of FASN inhibitor TVB-2640 [TVB-2640] with paclitaxel and trastuzumab in patients with taxane and trastuzumab-resistant, advanced HER2-positive breast cancer.
II. To estimate the ORR of the combination of TVB-2640 with paclitaxel and trastuzumab in patients with taxane and trastuzumab-resistant, advanced HER2-positive breast cancer.
SECONDARY OBJECTIVES:
I. For each patient cohort, to evaluate the safety profile of the combination of TVB-2640 with paclitaxel and trastuzumab.
II. For each patient cohort, to assess the clinical benefit rate (CBR), duration of response, and progression free survival of the combination of TVB-2640 with paclitaxel and trastuzumab.
III. To obtain a point and interval estimate of the difference in RR as well as the difference in CBR between cohort A and cohort B.
CORRELATIVE RESEARCH OBJECTIVES:
I. For each patient cohort, to assess the changes in FASN, phosphorylation (p)AKT, and pS6 expression in tumor tissue after the first cycle of the combination of TVB-2640 with paclitaxel and trastuzumab from pre-treatment levels.
II. For each patient cohort, to assess the changes in levels of cellular apoptosis in tumor tissue after the first cycle of the combination of TVB-2640 with paclitaxel and trastuzumab from pre-treatment levels.
III. For each patient cohort, to assess the changes in serum FASN after the first cycle of the combination of TVB-2640 with paclitaxel and trastuzumab from pre-treatment levels.
OUTLINE: Patients are assigned to 1 of 2 cohorts.
COHORT A: Patients receive FASN inhibitor TVB-2640 orally (PO) once daily (QD) on days 1-28, paclitaxel intravenously (IV) over 1-96 hours on days 1, 8, and 15, and trastuzumab IV over 30-90 minutes on days 1, 8, 15, and 22, and optionally every 21 days after 3 cycles and paclitaxel is discontinued. Cycles repeat every 28 days in the absence of disease progression or unexpected toxicity. Patients also undergo echocardiography (ECHO) and computed tomography (CT) or magnetic resonance imaging (MRI) at screening and on study and undergo collection of blood samples and biopsy on study.
COHORT B: Patients receive FASN inhibitor TVB-2640 PO QD on days 1-28 and trastuzumab IV over 30-90 minutes on days 1, 8, 15, and 22 and optionally every 21 days after 3 cycles and paclitaxel is discontinued. Patients also continue endocrine therapy of either anastrozole PO QD, exemestane PO QD, fulvestrant intramuscularly (IM) on days 1 and 14 of cycle 1 and day 1 of subsequent cycles, or letrozole PO QD. Cycles repeat every 28 days in the absence of disease progression or unexpected toxicity. Patients also undergo ECHO and CT or MRI at screening and on study and undergo collection of blood samples and biopsy on study.
After completion of study treatment, patients are followed up every 6 months for up to 3 years.
