Clinical Trial Summary

RATIONALE: Drugs used in chemotherapy, such as cisplatin and paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Everolimus may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth and by blocking blood flow to the tumor. Giving chemotherapy together with everolimus before surgery may make the tumor smaller and reduce the amount of normal tissue that needs to be removed. It is not yet known whether cisplatin and paclitaxel are more effective when given together with or without everolimus in treating patients with breast cancer.

PURPOSE: This randomized phase II trial is studying how well cisplatin and paclitaxel work when given together with or without everolimus in treating patients with stage II or stage III breast cancer.

Description:

OBJECTIVES:

Primary

• To determine the pathological complete response in patients with triple-negative, stage II or III breast cancer treated with neoadjuvant cisplatin and paclitaxel with or without everolimus.

Secondary

• To determine the safety profile of these treatment regimens.

• To evaluate tumor response to these treatment regimens as measured by ultrasound before definitive surgery.

• To evaluate the rate of breast conservation surgery after treatment with these regimens.

• To determine treatment-mediated changes in cell cycle position, proliferation, and apoptosis as well as status, levels, and phosphorylation state of S6K, p53, p73, and p63 and select p53 family target genes before and after initiation of paclitaxel.

• To isolate RNA and generate microarray data sets from pre- and post-treatment biopsy material to identify a pre-treatment gene signature that will predict response.

• To isolate RNA and generate microarray data sets from pre- and post-treatment biopsy material to identify a change in gene signature after the first treatment that will predict response.

• To isolate RNA and generate microarray data sets from pre- and post-treatment biopsy material to determine if previously established p63 and p73 gene signatures predict response to treatment.

• To isolate RNA and generate microarray data sets from pre- and post-treatment biopsy material to determine if a change will be observed in p63 and p73 gene signatures between pre- and post-treatment biopsies.

• To isolate RNA and generate microarray data sets from pre- and post-treatment biopsy material to determine if triple-negative breast cancers can be clustered into different subtypes on the basis of gene expression, given the size of the microarray data set that will be generated from this clinical trial and previous clinical trials (> 100 tumors).

• To isolate RNA and generate microarray data sets from pre- and post-treatment biopsy material to determine if p63 and p73 gene signatures can sub-classify triple-negative breast cancers.

OUTLINE: This is a multicenter study. Patients are stratified according to initial lymph node status (positive vs negative involvement) and tumor grade (low or intermediate vs high). Patients are randomized to 1 of 2 treatment arms.

• Arm I: Patients receive cisplatin IV over 1 hour and oral everolimus once weekly in weeks 1-12 and paclitaxel IV over 1 hour once weekly in weeks 4-12 in the absence of disease progression or unacceptable toxicity.

• Arm II: Patients receive cisplatin IV over 1 hour and oral placebo once weekly in weeks 1-12 and paclitaxel IV over 1 hour once weekly in weeks 4-12 in the absence of disease progression or unacceptable toxicity.

Approximately 3-6 weeks after the completion of neoadjuvant therapy, patients undergo partial or total mastectomy with lymph node evaluation. Patients may then receive additional chemotherapy or radiotherapy.

Patients undergo ultrasound-guided core biopsies at baseline and in weeks 1, 4, and 12 for analysis of proliferation, apoptosis, and pathway activity markers via IHC or western blotting and RNA microarrays.

Patients are followed up within 3 weeks after surgery.

• Platelet count >/=100,000/mm3

• Creatinine </=1.5X upper limits of normal

• Bilirubin, SGOT, SGPT </=1.5X upper limits of normal*

• for patients with Gilbert?s syndrome, direct bilirubin will be measured instead of total bilirubin.

• The patient must have not had anyprior chemotherapy for primary breast cancer.

• Patients with a prior history of contra-lateral breast cancer are eligible if they have no evidence of recurrence of their initial primary breast cancer within the last 5 years.

• Able to swallow and retain oral medication.

• Four days prior to biopsy procedures patients must be off medications that could increase risk of bleeding (i.e. ASA, NSAIDS, Coumadin, heparin products)

• Potential subjects must complete all screening assessments as outlined in the protocol.

• The pre-menopausal patient of childbearing potential must have had a negative pregnancy test and agreed to use birth control methods while participating in the study. Note: Women of childbearing potential and their male counterparts should use a barrier method of contraception during and for 3 months following protocol therapy.

Ineligibility Criteria

If patient is judged to be at risk for having had exposure to viral B or C hepatitis (i.e. illicit IV drug use, blood transfusion prior to 1990, body piercing, tattoos, etc.), appropriate testing should be performed (i.e. Hepatitis B surface antigen antibody, and Hepatitis C antibody)

• Active or uncontrolled infection requiring parenteral antibiotics.

• Dementia, altered mental status, or any psychiatric condition that would prohibit the understanding or rendering of informed consent.

Secondary	Number of Patients That Underwent Breast Conservation Surgery	Defined as patients that did not undergo complete removal of a cancerous breast (mastectomy).	at the time of surgery, week 15-18	No
Secondary	Clinical Tumor Response to Neoadjuvant Therapy as Measured by Ultrasound Immediately Before Surgery	Per RECIST criteria v. 1.0: measurable lesions: complete response (CR) disappearance of target lesions, partial response (PR) > 30% decrease in the sum of the longest diameter (LD) of target lesions, progressive disease (PD) > 20% increase in the sum of the LD of target lesions or appearance of new lesions, stable disease (SD) neither sufficient decrease nor increase of the sum of smallest sum of the LD of target lesions	After treatment, week 12-15	No
Secondary	Number of Patients With Each Worst-grade Toxicity Response	Tables represent the number of patients with their worst-grade toxicity at each of five grades (grade 1, least severe to grade 5, most severe) following NCI Common Toxicity Criteria. Not all participants necessarily have an adverse event, thus not everyone will be accounted for in worst-grade toxicities. Likewise, one participant can potentially have more than one event in various grades 1-5 which accounts for the difference in number of patients analyzed and total number in the worst-grade toxicity tables.	week 12	Yes
