Official title

An Investigation of the Antidepressant Effects of the Glycine Receptor Antagonist AV 101 (4-chlorokynurenine) in Major Depressive Disorder

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Background: \- Drugs and talk therapy help treat depression, but these treatments usually take quite a bit of time to work. Ketamine is a fast-acting antidepressant, but it has side effects like unusual dreams and experiences. The drug AV-101 may have the same antidepressant effects but fewer side effects. Researchers want to see if it is effective and safe for people with major depressive disorder. Objective: \- To see if the drug, AV-101 is safe and if it treats symptoms of major depressive disorder. Eligibility: \- Adults ages 18-65 with major depression without psychotic features. Design: * Participants will be screened under a separate protocol. * Participants will stay in the hospital for 12-14 weeks. * Phase 1 (2-7 weeks): participants will stop taking their medicines then not take any for 2 weeks. They will have several scans and other procedures. * Phase 2 (6-7 weeks): 2 weeks each of study drug and placebo once a day, with 2 weeks of no drugs in between. * Participants will have: * Physical exams * Interviews * Frequent blood collection. A needle will place a small plastic tube in the arm. Some blood samples will be taken through this tube. * 2 spinal taps (optional). The back will be numbed. A needle will insert a catheter between back bones. That will be left in for up to 30 hours. Spinal fluid will be collected through it. * 5 scans. Participants will lie in a machine with a magnetic field. The machine takes pictures of the brain and brain chemicals. * At the end of the study, participants will have medical evaluation, questions, and blood tests. Some may continue treatment at the clinic.
