Cancer-associated anorexia-cachexia is an insidious syndrome that has a major impact on the patient's quality of life, but is also associated with a significant reduction in survival. Despite its clinical importance, it remains a widely underestimated and untreated condition. Considering the scarcity of pharmacological measures, it is necessary to invest in studies that may contribute to the rational and effective treatment of this clinical condition. Mirtazapine has a special therapeutic potential because it is a well-tolerated drug with few adverse effects and with well-known orexigenic action in clinical practice.The objective of this study is to evaluate the effect of mirtazapine as a pharmacological measure in the management of cancer-related anorexia-cachexia in patients in palliative care. A randomized, double-blind clinical trial involving 52 cancer patients with anorexia-cachexia in palliative care will be conducted. Patients will be randomized to receive mirtazapine or megestrol and will be evaluated longitudinally for a period of 8 weeks. The primary endpoint will be to assess the effect of mirtazapine on anorexia and weight gain and secondary outcomes will be to assess the tolerability and safety of mirtazapine and the effect of mirtazapine on body composition, quality of life, and functional capacity of patients.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Change in appetite | Assessed by Edmonton Symptom Assessment Scale. This evaluation will be collected at baseline and after 8 weeks of follow-up. Changes in appetite will be divided into 3 categories according to the following definitions: appetite improvement will be a decrease = 2 points in Edmonton Symptom Assessment Scale, maintenance of appetite as an improvement or worsening of 1 point and worsening of appetite as deterioration = 2 points. | 8 weeks | |
Primary | Change in body weight | Assessed by body weight. This evaluation will be collected at baseline and after 8 weeks of follow-up. The weight changes will be divided into 3 categories according to the following definitions: weight improvement will be a gain = 1 kg, weight maintenance will be a loss < 500g or a gain < 1kg and weight loss will be a loss = 500g. | 8 weeks | |
Secondary | Change in body lean and fat mass | Assessed by body bioelectrical impedance and dual energy x-ray absorptiometry. They will be performed at baseline and after 8 weeks of follow-up. The body bioelectrical impedance will be performed using the ImpediMed DF50 mono-frequency system (ImpediMed Limited, Australia). The dual energy x-ray absorptiometry will be performed on the measuring table using the equipment-specific software. | 8 weeks | |
Secondary | Change in Quality of life | The European Organization for Research and Treatment of Cancer (EORTC) instrument QLQ-C30 Questionnaire will be used to assess quality of life at baseline and after 8 weeks of follow-up. | 8 weeks | |
Secondary | Assessment of muscle strength | Assessed by hand grip strenght measured by the use of a manual hydraulic dynamometer (Saehan, model SH 5.001, Koreia). It will be performed at baseline and after 8 weeks of follow-up. | 8 weeks | |
Secondary | Assessment of gait speed | The gait speed will be measured at 4 meters on usual speed. It will be performed at baseline and after 8 weeks of follow-up. The results will be expressed in m/s. | 8 weeks | |
Secondary | Physical Activity behaviour | Assessed by a tri-axial accelerometer to measure profile of spontaneous physical activity. It will be performed at first week and the last week of follow-up. | 8 weeks | |
Secondary | Incidence of treatment-related Adverse Events | Assessed by contact via telephone calls at weeks 1, 2, 3, 5 and 6 for information regarding treatment-related adverse events. The questioning about the occurrence of treatment-related adverse events will also be performed at the outpatient clinic at baseline and weeks 4 and 8 during the follow-up. | 8 weeks |
