Comparison Between Mirtazapine and Megestrol for the Control of Anorexia-cachexia in Cancer Patients in Palliative Care.

July 5, 2023 updated by: Nereida Kilza da Costa Lima, University of Sao Paulo

Randomized, Double-blind Clinical Trial of the Use of Mirtazapine Versus Megestrol for the Control of Anorexia-cachexia in Cancer Patients in Palliative Care.

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.

Detailed Description

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. Unintentional weight loss can predict a poor prognosis in cancer patients which is most likely due to decreased doses of treatment. 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. It has been shown to have side effects of increased appetite and weight gain in cancer subjects with depression and nausea, as well as in non-depressed cancer patients, but there are not, as yet, randomized controlled trials showing its effect on cancer-associated anorexia-cachexia. 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. After the initial evaluation and randomization, patients will be reassessed after 4 and 8 weeks at an outpatient clinic where they will be evaluated for the following variables: (1) General and demographic characteristics; (2) Usual food intake; (3) Anthropometric evaluation; (4) Presence and degree of symptoms using the Edmonton Symptom Assessment System; (4) Status performance using the Karnofsky performance status; (5) Quality of life using the QLQ-C30 Questionnaire; (6) Depression using the Hospital Anxiety and Depression Scale; (7) Prognosis using the Palliative Prognostic Score; (8) Evaluation of functional capacity using hand grip strength and gait speed; (9) Body composition using electrical bioimpedance and dual energy x-ray absorptiometry; (10) Physical Activity Behaviour using a tri-axial accelerometer. Patients will also be contacted via telephone calls at weeks 1, 2, 3, 5 and 6 for information regarding adverse events and drug compliance. The questioning about the occurrence of adverse events will also be performed at the outpatient clinic. Self-report of ingestion of tablets and counting of tablets on return of packages at the end of the study will be used to determine patient compliance. It is expect that use of mirtazapine can bring benefits increasing appetite and the body weight in cancer patientes in palliative care compared to the use of megestrol.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in appetite
Time Frame: 8 weeks
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
Change in body weight
Time Frame: 8 weeks
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 Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in body lean and fat mass
Time Frame: 8 weeks
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.

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
Assessment of muscle strength
Time Frame: 8 weeks
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
Assessment of gait speed
Time Frame: 8 weeks
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
Physical Activity behaviour
Time Frame: 8 weeks
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
Incidence of treatment-related Adverse Events
Time Frame: 8 weeks
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.
