Brief summary
The LEAP-DB study will be conducted to validate the utility of EEG biomarkers as an aid to antidepressant treatment selection in adults with MDD.
Detailed description
The LEAP-DB study is an 8-week, multicenter, randomized, blinded study to evaluate the performance of EEG-based biomarkers in predicting treatment outcome. Study participants will be randomized in a 1:1 ratio to receive either duloxetine or bupropion and followed for 8 weeks.

Exclusion criteria
* Diagnosis of bipolar disorder or a psychotic disorder based on the Structured Clinical Interview for DSM-5. * Concurrent use of antipsychotics or mood stabilizers * Use of hypnotics, anxiolytics or opiate pain medications greater than three days per week and unable to reduce use to three or fewer days per week on an as needed basis * Pregnant or breastfeeding * Severe impediment to vision, hearing, comprehension, and/or hand movement that interferes with study tasks * Active substance use that interferes with ability to consent and/or complete assessments * Any contraindication to EEG (e.g. requiring high concentration oxygen) * Employees/family of employees of clinic site * Participation in another research study that began within less than 2 months prior to the first study visit
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Response rate on the 16-item patient-reported Quick Inventory of Depressive Symptoms (QIDS-SR) at the week 8 endpoint as a function of biomarker score | 8 weeks | The Quick Inventory of Depressive Symptomatology (QIDS-SR) is a 16 item self-report scale that measures depressive symptoms. The QIDS assesses the severity of all DSM-V criterion items required to diagnose a major depressive episode. It asks the patient to rate each of 16 items on a scale from 0 to 3. Additionally, it states the frequency and severity of symptoms that patients should consider while responding to items in the survey. Each item in the survey asks about depressive symptoms that the patient may have experienced in the past seven days. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Percentage decrease in depressive symptoms on the QIDS-SR at the week 8 endpoint as a function of biomarker score | 8 weeks | Quick Inventory of Depressive Symptoms (QIDS-SR) |
| Absolute score decrease from baseline to the week 8 endpoint on the QIDS-SR as a function of biomarker score | 8 weeks | Quick Inventory of Depressive Symptoms (QIDS-SR) |
