Lead Doctor: Dr. Jennifer Grunfeld
HREC Committee: This study has been reviewed and approved by the Human Research Ethics Committee of Sydney Local Health District


About 350 million people are dealing with major depressive disorder (MDD) worldwide. MDD can cause barriers to living life to the fullest. Linked to harmful outcomes, it can significantly influence the well-being of a person as well as society. Currently, antidepressants only help about half of those who take this form of medication. Despite the many treatment options available, there is still a need for more effective therapies to produce fast symptom resolution. 

Researchers are exploring a new medication for treatment-resistant depression. The study is investigating the effectiveness of a new oral form of treatment for those who have failed to respond to antidepressant medication.  

Interested participants need to have been diagnosed with major depressive disorder (MDD) and be between 18 and 80 years old. They will need to attend the research site in Frankston for 19 study visits, over approximately 20 weeks. At the end of the study, eligible participants can enter a second study, which allows them to continue the study medication for a further 6 months.
