The purpose of this study is to find out if remeron, also called mirtazapine, can help you prevent weight loss while on treatment for your cancer. Remeron is currently used to treat depression and has not been approved by the Food and Drug Administration for use to treat weight loss.
Weight loss in cancer patients can be the result of inadequate intake or absorption of nutrients and/or tumor-induced weight loss due to metabolic changes the tumor is creating in the body (1). Inadequate intake resulting in a starvation state can simply be the result of eating less due to depression, nausea/vomiting, feelings of fullness, and taste changes (2). Though not intentional the weight loss caused by these symptoms can be explained and reversed by increasing intake of nutrients. Unintentional weight loss induced by the tumor can be caused by multiple physiological factors that increase the catabolism of muscle and fat and increased nutrient intake alone may not reverse the weight loss. Unintentional weight loss can predict a poor prognosis in cancer patients which is most likely due to decreased doses of treatment (3-5). Usual care for weight loss in cancer patients varies among practitioners and can include nutrition counseling by a registered dietitian or by the practitioner themselves. Treatment can vary from counseling patients to increase intake of nutrient dense foods to prescribing medications in order to improve appetite or mood, to decrease feelings of fullness, or to control nausea/vomiting, etc. (6). However, these interventions do not always work. For varied reasons not all patients are able to improve their oral intake of food items and in patients with tumor induced weight loss increased oral intake does not improve the metabolic changes. Anti-depressant medications have weight related side effects (7-9). Mirtazapine has been shown to have side effects of increased appetite and increased weight in cancer subjects studied for use with depression and nausea. (10-13). These results appeared to range from changes in appetite to changes seen in metabolic processes such as changes in the cytokine system to reduce inflammation seen in cachectic patients. Therefore, using mirtazapine in cancer patients even without depression may help to stop unwanted weight loss and increase survival by allowing patient to complete prescribed treatment.
