Anxious Depression
Brief summary
Acute, double-blind, adaptively randomized treatment with duloxetine or escitalopram, followed by double-blind, randomized adjunctive treatment with clonazepam or pregabalin for persistent symptoms.
Detailed description
The study will consist of 2 phases (Figure 1). Eighty-four adults will be enrolled in Phase 1 and will be adaptively randomized (initially 1:1) to acute, double-blind treatment with escitalopram or duloxetine for 11 weeks. Remission status will be determined at week 10. Remitting patients (CGI-S ≤2) will resume treatment as usual, which may consist of outpatient referral. Non-remitting patients (CGI-S ≥3), will continue into Phase 2 and will be randomized to adjunctive clonazepam or pregabalin for 8 weeks. Twenty adults treated with escitalopram (or its racemic equivalent, citalopram) or duloxetine for ≥6 weeks (at screening) will be enrolled into Phase 2 and will be randomized to receive adjunctive clonazepam or pregabalin for 8 weeks.
Interventions
Escitalopram, a SSRI, commercially known as LexaproTM, is commonly prescribed for anxiety disorders and is FDA-approved for acute and maintenance treatment of MDD and GAD.
Duloxetine, a SNRI, commercially known as CymbaltaTM, is FDA-approved for the treatment of GAD, MDD, diabetic peripheral neuropathic pain, fibromyalgia, and chronic musculoskeletal pain in adults.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from Baseline in Hamilton Anxiety Rating Scale (HAM-A) total score | Week 2 to 20 | The HAM-A rating scale is a test of 14 items measuring the severity of anxiety symptoms. Each item is rated on a 5-point ordinal scale, ranging from 0 (not present) to 4 (severe). Total scores range from 0 to 56. A lower score is favorable. |
| Change from Baseline in the Clinical Global Impression of Severity (CGI-S) | Week 2 to 20 | CGI-S is a seven point scale where 1=Normal and 7=Among the most extremely ill patients. |
