Summary

This trial is testing two medications, olanzapine and mirtazapine, to see which one helps cancer patients keep their weight and appetite. Cancer patients often lose weight and appetite, and these drugs might help by making them feel better emotionally and physically. Olanzapine and mirtazapine have been shown to improve appetite and reduce nausea in cancer patients, which can help with weight maintenance.

Who is the study for?
This trial is for adults with advanced cancer who have lost more than 5% of their weight unintentionally over the last 3-6 months, despite nutritional support. They must be able to consent, communicate effectively, and have a life expectancy of at least 4 months. Those on dexamethasone or undergoing chemotherapy can join. People using Marinol recently, with abnormal heart rhythms or liver function, or primarily fed intravenously cannot participate.
What is being tested?
The study aims to compare the effectiveness of two medications, Olanzapine and Mirtazapine, in preventing further weight loss and appetite loss in patients with advanced stage cancer. It will assess which drug better helps manage these symptoms associated with cancer.
What are the potential side effects?
Possible side effects from Olanzapine include drowsiness, increased appetite leading to weight gain, dry mouth, constipation and fatigue. Mirtazapine may cause similar side effects such as sleepiness, elevated hunger resulting in potential weight gain along with dry mouth.
