About this trial
Major depressive disorder (MDD) is a significant public health problem and leading cause of worldwide disability. Treatment resistance is common in MDD, however, for these individuals, targeted noninvasive brain stimulation is an alternative. Repetitive transcranial magnetic stimulation (rTMS) and more recently, theta-burst stimulation (TBS), are the noninvasive brain stimulation modalities with the largest evidence base in MDD. Although efficacious, an unacceptable proportion of patients do not significantly improve, and several aspects of the TMS parameter space are under investigation to enhance clinical outcomes.
DCS has been shown in a randomized trial of more than double the percent response and remission from traditional TMS. When a one day (ONE-D) TMS protocol was combined with DCS, the measured response rate was 87% at one week.
This trial will compare response and remission at six weeks following neuronavigated robotic-enabled Transcranial Magnetic Stimulation + NRX-101 (D-cycloserine/lurasidone) vs. TMS+placebo.
Eligibility criteria
Qualifiers
Non-childbearing potential: physiologically incapable of becoming pregnant (i.e., permanently sterilized [status posthysterectomy, bilateral tubal ligation], or post-menopausal with last menses at least one year prior to Screening); or
Disqualifiers
Myocardial infarction within 1 year of Screening.
Diagnosis of angina pectoris.
Prolonged QTc interval, as measured by Fridericia's correction formula (QTcF) ≥450 msec at Screening for males or ≥ 470 msec for females on 2 of 3 measurements at least 15 minutes apart prior to randomization on Day 1. 16. Diagnosis of chronic lung disease, excluding asthma. 17. Lifetime history of any of the following: neurologic conditions with structural cerebral damage, traumatic brain injury, multiple sclerosis, surgical procedures involving the brain or meninges, meningoencephalitis, degenerative central nervous system (CNS) disorder (e.g., Alzheimer's Disease, Parkinson's Disease), mental retardation, stroke (ischemic or hemorrhagic), intracranial abscess, or any other disease/procedure/accident/intervention that, according to the clinician, is deemed associated with significant injury to, or malfunction of, the CNS. 18. History of epilepsy, personal history of seizure, family history of epilepsy or seizure in a first degree relative. 19. Diagnosis of parenchymal or leptomeningeal cancer.
Unstable diabetes mellitus defined as glycosylated hemoglobin (HbA1c) >8.0 percent at Screening.
