Preventing the Return of Depression in Elderly Patients Clinical research trials and Preventing the Return of Depression in Elderly Patients healthcare trials occur in a lot of of places across the United States. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally assess the effectivity of new does drugs. The role of the studies / undertakings is to solve specific human healthcare questions. Clinical trials are a popular way for doctors, government agencies, and private sector companies to find treatments for all kinds of conditions, including Preventing the Return of Depression in Elderly Patients. Preventing the Return of Depression in Elderly Patients Clinical Trials and other clinical trials allow for volunteers to access health treatment choices before they are available to the general public. Many times the test subjects get treatment for without cost, and sometimes they are compensated for their time. Occasionally there is a cost for a Preventing the Return of Depression in Elderly Patients clinical trial. Test subjects typically receive the most effective healthcare possible for their Preventing the Return of Depression in Elderly Patients condition. Risks are a reality, nonetheless, and could include extra or frequent dr. calls, health hazards (perhaps life-jeopardizing), and/or the treatment being ineffective. Trials are federally regulated with rigid guidelines to protect clinical trials subjects.

Preventing the Return of Depression in Elderly Patients



Preventing the Return of Depression in Elderly Patients

For Condition: Depression
Status: No longer recruiting
Sponsor(s): National Institute of Mental Health (NIMH) ,
Synopsis: The purpose of this study is to compare the effectiveness of two doses of nortriptyline in elderly patients whose depression returned after stopping treatment. Nortriptyline is an antidepressant. This study enrolls patients who were treated for depression in an earlier research study and whose depression has returned since stopping treatment. Patients are treated for 4 months to bring the depression under control. Patients are then assigned randomly (like tossing a coin) to receive either the full dose of nortriptyline or half the usual dose of nortriptyline. Patients continue taking nortriptyline for 2 years or until a major depression returns. Throughout the study, patients are monitored for symptoms of depression and other side effects.
Details: To determine whether elderly (60-80 years old) depressed patients who cannot sustain a remission without medication must be maintained at full acute-treatment dose. To compare the efficacy of full-dose vs half-dose nortriptyline (NT) in preventing recurrences of major depression in the elderly. To determine whether those patients who experience a recurrence while in a maintenance placebo condition (Study I) require 100 percent of their acute-treatment dose of NT to prevent subsequent recurrences or can be successfully maintained on 50 percent of their acute-treatment dose (Study II). Investigators expect a pool of 60 patients from Study I to become eligible for Study II (the full-dose/half-dose maintenance trial). After treatment of the recurrence and following 16 weeks of stabilization therapy, patients are randomized to 1 of 2 maintenance therapy cells: full-dose NT or half-dose NT. Maintenance lasts 2 years or until recurrence of major depression. The following are assessed: differences in recurrence rates and time to recurrence under full-dose vs half-dose conditions; differences in symptomatic ratings of depression, suicidal ideation, social adjustment, and side effects; and differences in compliance rates as determined by variability in level-to-dose (L/D) ratios. Exploratory data analyses are used to generate a hypothetical profile of elderly patients who can remain well on half-dose maintenance nortriptyline.
