About

The purpose of this research study is to see how certain hormones cause changes in mood and thinking in some depressed patients and to determine the effectiveness of mifepristone in treating some forms of depression. This study is conducted in conjunction with an observational study "Clinical and Biological Characteristics of Psychotic Depression".

Full description

Eligibility Procedures: Before entering the study and prior to any other procedures, you will be asked to read and sign this consent form. To determine if you are eligible for our study, you will then have a general medical (including menstrual cycle history on female patients) and psychiatric history taken, a physical examination, your vital signs (blood pressure, pulse), height, weight and waist/hip ratio will be measured, as well as various psychiatric evaluations will be conducted. You will be randomly (by chance) assigned to receive mifepristone or placebo (an inactive substance). Half of the participants in this research study will receive placebo, and half will receive mifepristone. Neither you nor your study doctor will know which of the two you are receiving. Treatment will begin in the morning of Treatment Day 1 and conclude on Treatment Day 8 for a total treatment period of 8 days. You will take the medication once a day in the morning. The dose was originally 600 mg but was changed to 1200 mg per day after the 4th patient. You will not be able to take any new medications (other than the study drug) or make changes to your current medications while participating in this part of the study unless ordered by the study physician. On treatment Day 1, you will come to our office for an interview and we will evaluate your mood and other psychiatric symptoms. Additionally, we will take your vital signs and draw blood to administer clinical laboratory tests. You will meet with the study physician and will then be given 4-days of medication to take home with you and self-administer each morning. On Treatment Day 4, you will come back to our office. We will evaluate your mood, take your vital signs and you will meet with the study physician. It is important that you discuss with your study physician or the research study staff all unpleasant or unusual symptoms that you may experience. Any positive effects that are experienced should be discussed as well. You will be given an additional 4-days of medication to take home with you to self-administer each morning. On Treatment Day 8, we will re-evaluate your mood, take your vital signs and repeat the blood and urine lab tests. You will also meet with the study physician to discuss any side effects. If you are participating in the blood draw portion of this study, you will be admitted to the GCRC on this day for an overnight stay. At 2pm on Treatment Day 8, you will have an IV line inserted into one arm for hourly blood samples from 2pm, 4pm, then 6pm until 9am on Treatment Day 9. At 9am on treatment Day 9, 10 mls of blood will be taken for Mifepristone concentration. A total of 82mls (approximately 5.5 tablespoons) of blood will be drawn. You will be discharged from the GCRC following breakfast. On Treatment Day 15, we will re-evaluate your mood and you will meet with the study physician to discuss any side effects. On Treatment Day 22, you will be readmitted to the GCRC, where nurses will take your vitals signs and repeat the clinical laboratory tests. We will also reevaluate your mood, and you will meet with the study physician to discuss any side effects. If you have participated in portions or all of the baseline protocol (protocol # 13088) you will repeat neuropsychological, MRI and blood draw procedures accordingly. If you did not participate in the baseline protocol, you will be assessed for safety and discharged. You will have another functional MRI (a picture taken of your brain using a magnet while you are administered a series of tasks). This MRI scan procedure will take approximately 1 hour. You will be given a series of neuropsychological tests to assess your memory and concentration. You will be asked to complete several questionnaires during your hospital stay. These questionnaires ask for your views about your personality, your childhood, your quality of life, your mood and a variety of aspects of your daily functioning. The questionnaires may be completed anytime during your overnight stay and will take about 2.5 hours to finish. On treatment Day 22, you will have an IV line inserted into one arm for hourly blood samples taken at 2pm, 4pm and then hourly from 6pm to 9am. A total of 72 ml's (approximately 5 tablespoons) of blood will be drawn. At 2pm on Treatment Day 23, you will have another IV line placed in your arm to draw hourly blood samples used for the measure of ACTH and cortisol. These blood samples are taken in small amounts (approximately 1 teaspoon) and will be collected at 2pm and then on the hour, every hour, starting at 3pm and ending at 7pm, then every 30 minutes until 12pm. At 3pm, you will be given 0.5mg (five 0.1mg tablets) of Fludrocortisone. At 4pm, 10 mls of blood will be taken for Mifepristone concentration. Following the last blood draw at 12pm, a blood sample will be taken for clinical laboratory assessment to ensure your safety following Fludrocortisone administration. A total of 76ml's (approximately 5 tablespoons) of blood will be drawn. The IV line will then be removed and your vital signs will be assessed. The following morning, the study physician will contact the experimental pharmacy and find out whether you have received placebo (no medication) or mifepristone. If you have been treated with mifepristone, this will mark the end of your study participation and the research coordinator will discuss follow-up assessments with you. The follow up assessments will be as follows: mood assessments will be performed via phone on weeks 1 and 2 and months 1, 3, 6, and 12 after completion of the study. These assessments will take a maximum of 1 hour to complete. The physician will also confirm your continued care and treatment with your primary treating psychiatrist. You will then be discharged from the GCRC and the hospital. If you have been on the placebo, you will be offered an 8-day open-label trial of mifepristone.
