The long-term objective of this research is to understand the molecular mechanisms of
acquired endocrine resistance in breast cancer. Identifying these mechanisms is critical to
the implementation of novel therapeutic strategies that can target and overcome altered gene
networks involved in controlling breast cancer progression. While patients with tumors over
expressing HER1, 2, or 3 have been shown to have reduced survival, patients with those
tumors which overexpressed HER4 (erbB4) had increased survival (Witton 2003).
This is a non-randomized, single-arm, proof of principle trial. Selected are patients with
advanced-stage breast cancer whose tumors are ER+, tamoxifen refractory. Histologically
proven diagnosis of recurrent or metastatic breast cancer is advanced cancer for which there
is no treatment available which would have a reasonable chance of cure. Treatment failure is
defined as tumor progression after chemotherapy and tamoxifen therapy. Patients will be
given five 30mg doses of HDAC inhibitor (LBH) over a period of two weeks. A dose will be
taken on Days 1,3,5,8 and 10. Patients will have a diagnostic tumor biopsy prior to drug
administration and a diagnostic biopsy within 48 hours (2 days) of the last dose. Primary
endpoints are measured by biopsy of palpable tumor with immunohistochemical staining for
ERBB4. Secondary end points include the evaluation of cell death, apoptosis, with
immunohistochemical staining for DNA breaks by TUNEL assay.

Inclusion Criteria: 1. Patient age is = 18 years 2. Female 3. Stage IV tamoxifen-refractory breast cancer (progression of at least 25% in diameters of at least one measurable lesion while taking tamoxifen or occurrence of a new lesion while taking tamoxifen), including first occurrence of metastasis within 12 months of completing adjuvant therapy with tamoxifen 4. No concurrent use of other HDAC inhibitors 5. Palpable disease 6. Patient has an Eastern Cooperative Oncology Group (ECOG) performance status of = 2 7. Ability to provide written informed consent obtained prior to participation in the study and any related procedures being performed 8. No chemotherapy in the 14 days prior, or radiation therapy to index lesions in the thirty days prior to initiation of treatment on this study 9. No other concurrent chemotherapy; surgery or radiation therapy during the treatment phase of this protocol 10. No active major medical problems, including untreated or uncontrolled infections 11. No known CNS involvement by tumor 12. Patients must meet the following laboratory criteria: - Hematology: - Neutrophil count of >1500/mm3 - Platelet count of > 100,000/mm3L - Hemoglobin = 9 g/dL - Biochemistry: - AST/SGOT and ALT/SGPT = 2.5 x upper limit of normal (ULN) or = 5.0 x ULN if the transaminase elevation is due to disease involvement - Serum bilirubin = 1.5 x ULN - Serum creatinine = 1.5 x ULN or 24-hour creatinine clearance = 50 ml/min - Total serum calcium (corrected for serum albumin) or ionized calcium = LLN - Serum potassium = LLN and = HLN - Serum sodium = LLN and = HLN - Serum albumin = LLN or 3g/dl - Patients with any elevated Alkaline Phosphatase due to bone metastasis can be enrolled 13. Baseline MUGA or ECHO must demonstrate LVEF = the lower limit of the institutional normal. 14. TSH and free T4 within normal limits (patients may be on thyroid hormone replacement) 15. An echocardiogram > 50% 16. Women of childbearing potential (WOCBP) must have a negative serum pregnancy test within 7 days of the first administration of study treatment. and must be willing to use two methods of contraception one of them being a barrier method during the study and for 3 months after last study drug administration Exclusion Criteria: 1. Prior HDAC, DAC, HSP90 inhibitors or valproic acid for the treatment of cancer 2. Patients who will need valproic acid for any medical condition during the study or within 5 days prior to first panobinostat treatment 3. Impaired cardiac function including any one of the following: - Complete left bundle branch block or use of a permanent cardiac pacemaker, congenital long QT syndrome, history or presence of ventricular tachyarrhythmias, clinically significant resting bradycardia (<50 beats per minute), QTcF > 450 msec on screening ECG, or right bundle branch block + left anterior hemiblock (bifascicular block) - Presence of atrial fibrillation (ventricular heart rate >100 bpm) - Previous history angina pectoris or acute MI within 6 months - Congestive heart failure (New York Heart Association functional classification III-IV) or baseline MUGA/Echo shows LVEF < 45% 4.
