Outcome Measures
Primary Outcomes (2)
Change from Baseline in Hamilton Anxiety Rating Scale (HAM-A) total score
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.
Week 2 to 20
Change from Baseline in the Clinical Global Impression of Severity (CGI-S)
CGI-S is a seven point scale where 1=Normal and 7=Among the most extremely ill patients.
Week 2 to 20
Study Arms (2)
Escitalopram
ACTIVE COMPARATORAdaptively randomized, double-blind treatment with escitalopram for 11 weeks in Phase 1. Non-remitting patients will be randomized in Phase 2 to adjunctive clonazepam or pregabalin for 8 weeks. Additionally, adults who are already treated with escitalopram or citalopram for at least 6 weeks prior to screening, may enter Phase 2 and be randomized to adjunctive clonazepam or pregabalin for 8 weeks.
Duloxetine
ACTIVE COMPARATORAdaptively randomized, double-blind treatment with duloxetine for 11 weeks in Phase 1. Non-remitting patients will be randomized in Phase 2 to adjunctive clonazepam or pregabalin for 8 weeks. Additionally, adults who are already treated with duloxetine for at least 6 weeks prior to screening, may enter Phase 2 and be randomized to 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.
Eligibility Criteria
You may qualify if:
- Written, informed consent.
- Patients must be fluent in the English.
- to 50 years of age, inclusive, at Visit 1.
- Patients must meet DSM-5 criteria for generalized, social and/or separation anxiety disorder and/or panic disorder, confirmed by the MINI.99 Patients may also meet criteria for persistent depressive disorder or major depressive disorder however, these may not be the primary focus of treatment.
- HAM-A score ≥20 at Visits 1 and 2.
- Clinical Global Impressions- Severity (CGI-S) score ≥4 at Visits 1 and 2.
- No clinically significant abnormalities on physical examination and EKG.
- Negative pregnancy test at Visit 1 in females.
- Negative urine drug screen at Visit 1.
- Sexually active patients must practice a reliable method of contraception (Section 15.0) that will continue for the duration of the study and for a minimum of 30 days following the end of study participation. Reliable methods of contraception are defined below; other forms of contraceptives (pharmacological and/or non-pharmacological) are not accepted:
- Surgical sterilization
- Oral contraceptives (e.g. estrogren-progestin combination or progestin)
- Transdermally-delivered contraceptives (e.g., Ortho-Evra), depot injections (e.g., Depo-Provera)
- Vaginal contraceptive ring (e.g., NuvaRing), contraceptive implants (e.g., Implanon, Norplant II/Jadelle)
- An intrauterine device
- +2 more criteria
You may not qualify if:
- DSM-5 diagnosis other than generalized anxiety, social anxiety, separation anxiety or panic disorder(s) that is the primary focus of treatment.
- A history of intellectual disability.
- Suicide risk as determined by either: (1) any suicide attempt within the past 6 months and/or (2) significant risk at Visit 1 (Screening) or Visit 2 (Baseline), as judged by the Investigator.
- Allergy, intolerance, non-response or hypersensitivity to escitalopram, duloxetine, pregabalin or clonazepam.
- Subjects taking other medications that require a taper or washout of more than 5 days.
- Patients who have initiated/terminated psychotherapy/behavior therapy within 1 month before Visit 2 (Baseline) will be excluded; if the patient is engaged in psychotherapy, it must have been stable for 1 month prior to baseline.
- A clinically-significant medical illness.
- QTc \>450 in males or \>460 in females (prolonged QTc based on American Heart Association recommendations for Standardization and Interpretation of the EKG100
- Alcohol or substance use disorder within 6 months of baseline (nicotine use is permitted).
- Positive urine pregnancy test/pregnancy or breast feeding.
- A positive urine drug screen.
- Patients who are unable to swallow capsules.
