Aspect Medical Systems, Inc. (NASDAQ: ASPM) today announced that
two companion articles highlighting results from the BRITE-MD
(Biomarkers for Rapid Identification of Treatment Effectiveness
trial in Major Depression) were published in the September issue of
the journal Psychiatry Research. The BRITE trial results
demonstrate that Aspect’s EEG-based Antidepressant Treatment
Response (ATR) indicator is a significant predictor of patient
response and remission after one week of treatment with the
commonly prescribed antidepressant escitalopram. Retrospective
analysis of BRITE data also suggests that ATR has the potential to
positively impact depression treatment outcomes by helping
clinicians select the most effective antidepressant for each
patient early in their treatment.
“The publication of BRITE trial results is a major milestone in
our efforts to develop clinically useful biomarkers for predicting
treatment response in Major Depressive Disorder. The BRITE results
demonstrate that early changes in frontal EEG may help predict
treatment outcome in as short a time as one week after the start of
medication. We are hopeful that these results will be replicated by
other researchers, and that an EEG biomarker can be used to help
clinicians improve the care of patients suffering from depression,”
said Andrew Leuchter, M.D., professor of Psychiatry at the Semel
Institute for Neuroscience and Human Behavior at UCLA, principal
investigator for the trial, and chair of Aspect’s Neuroscience
Advisory Board.
The BRITE trial was conducted in collaboration with leading
investigators from nine facilities across the United States and
enrolled 375 patients. Patient response was defined by researchers
as a 50 percent improvement in depression symptoms as measured by
the Hamilton Depression Rating Scale (HAM-D) after seven weeks of
treatment, and remission was defined as recovery from depression
