Panobinostat & Bortezomib in Pancreatic Cancer Progressing on Gemcitabine Therapy

Study Overview
=================
Brief Summary
-----------------
Cancer results from multiple mutations which cause cells to grow uncontrolled. It therefore may be necessary to inhibit several oncogenic targets to affect cancer cell growth. Studies have shown that panobinostat (LH589) causes a wide range of effect on endothelial cells that lead to inhibition of tumor angiogenesis (a fundamental step in the transition of tumors from a dormant state to a malignant one). Bortezomib triggers cell death in pancreatic cancer cells but the mechanism is not well defined but has been determined to be cytostatic. Combining these two drugs may work together in the treatment of pancreatic cancer.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Progression-Free Survival | Median number of months before disease progressed in patient on gemcitabine when treated with the combination of panobinostat and bortezomib. Progression free survival is measured from randomization until the subject has documented disease progression by an objective measure. Subjects must be alive with no more than 20% increase in tumor size to qualify for progression free survival. Changes in tumor size are defined by RECIST criteria. | Up to 1 Year | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants by Tumor Response | Number of patients whose tumor has responded to study therapy is determined using Response Evaluation Criteria In Solid Tumors. Progressive Disease (PD) is assessed if the sum of the diameters has increased by ≥ 20% and ≥ 5 mm from nadir (including baseline if it is the smallest sum). Objective response is measured by tumor reduction as defined in the RECIST criteria. Tumor shrinkage must be at least 30% to qualify as an objective response. | Up to 1 Year | 
| Duration of Response | Duration of response is calculated as (Date of First Disease Progression or Death as a Result of any Cause whichever Comes First - Date of First Objective Status Assessment of Confirmed Complete or Partial Response as defined by RECIST criteria). | Up to 1 Year |
