Megestrol Acetate With or Without Mirtazapine in Treating Cancer Patients With Weight Loss or Loss of Appetite

This randomized phase II trial studies the safety and efficacy of megestrol acetate given with or without mirtazapine in treating cancer patients with weight loss and loss of appetite. To date, no pharmacologic interventions have been approved by FDA to treat cancer anorexia-cachexia syndrome (CACS). Megestrol acetate has been shown to increase appetite in cancer patients. Adding mirtazapine may provide a much more effective treatment and help improve quality of life.
