Condition(s) targeted: Advanced Cancer; Weight Loss

Intervention: Olanzapine (Drug)

Phase: Phase 1

Status: Completed

Summary

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.

Clinical Details

Official title: Phase I Dose-Finding Pilot Study of the Safety and Tolerability of Olanzapine in Patients With Advanced Cancer and Weight Loss

Study design: Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Maximum Tolerated Dose (MTD)

Detailed description: Olanzapine is approved for the treatment of schizophrenia and bipolar disorder. However, patients who have received this drug for these reasons have also experienced weight gain. Further studies in patients with cancer showed an improvement in appetite, a decrease in nausea, and a control of flushing (feeling of warmth) and sweating. If you are found to be eligible to take part in this study and before you receive your first dose of Olanzapine, you will have routine blood tests (about 2 teaspoons). You will be asked a series of questions about your nutrition and how well you are able to perform daily activities. These questions should take about 20 minutes to answer. Your answers will help the study doctor decide if the study drug is helping you gain weight and if your weight gain

is helping you feel better. You will also have an electrocardiogram (ECG - a test to measure

the electrical activity of the heart). Women who are able to have children must have a negative blood pregnancy test (about 1 teaspoon). After the tests above are completed, you will begin receiving Olanzapine. The study drug will be taken by mouth once daily at bedtime for 28 days in a row. Seven different doses of the drug are planned with 6 patients enrolled on each level. The level you are assigned to will depend on when you are enrolled on this study. All participants will begin taking the

same strength of the study drug. This will gradually increase about every 3 - 14 days until

you reach the highest strength of the study drug for the dose level to which you are assigned. About every 2 weeks during this study for the first month and then about once a month thereafter, you will have a physical exam, including measurement of your vital signs (blood pressure, heart rate, temperature, and breathing rate), and your medical history will be discussed. You will also have routine blood tests (about 2 teaspoons) to check your general health. You will continue to receive the highest strength of the study drug for the dose level to which you are assigned for about 4 months unless you have intolerable side effects or if your weight continues to decrease. The study doctor will decide if you should continue receiving Olanzapine after 4 months. This is an investigational study. The FDA has approved Olanzapine for mental health diseases (schizophrenia, acute mania, and bipolar disorder). Its use in preventing weight loss is experimental. Up to 57 patients will take part in this study. All will be enrolled at MD Anderson.
