Summary
Brief summary (as posted)
The goal of this clinical research study is to find the highest tolerable dose of the drug Olanzapine that can be given to patients with advanced cancer who are experiencing weight loss. Researchers want to find out if Olanzapine can help decrease weight loss in patients who are experiencing it because of cancer. How this drug affects performance status, cancer-related symptoms, and nutritional status in patients with advanced cancer will also be studied.
