This study is for patients that have been diagnosed with ovarian cancer who are taking bevacizumab. This study is testing two investigational drugs called nelfinavir and hydroxychloroquine. "Investigational" means it has not been approved by the United States Food and Drug Administration (FDA) for the treatment of cancer. The primary purpose of this study is to see if these two medications in combination with bevacizumab are safe and effective in ovarian cancer. These drugs will be given by mouth. Participants in this study can expect to be in this study for 6 months for data collection, but may continue on the study medications longer if seeing benefit.
