Phase I BKM120/Abraxane in Solid Tumors, Expansion Phase Recurrent Endometrial or Ovarian Cancer

The purpose of the first part of this study or the dose escalation portion of the study is to determine what dose of BKM120 and Abraxane is safe to give when the two drugs are used at the same time in patients who are diagnosed with a solid cancer. A solid cancer is a cancer that does not involve the blood, bone marrow or lymph nodes. Dose escalation determines the least toxic and most effect dose of this drug combination for treatment. Once this dose is established, it will be used for the dose expansion phase of the study where we will determine the effect of BKM120 and Abraxane in women diagnosed with a recurrent endometrial or ovarian cancer. We will see whether the combination of both drugs improves the response and survival of patients treated on the two drug regimen. Also we will try to find out whether there are changes in tumors that can help us determine what patients are more likely to respond to BKM120 and Abraxane.
