- All
- Target Recruitment
- 26
- Men and women, age 18-60.
- Participants must have a level of understanding sufficient to agree to all tests and examinations required by the protocol and must sign a written informed consent document. We determine whether they have a sufficient understanding of the study procedures and risks by asking them to explain what's involved in the study and to give examples of study risks and benefits.
- Participants must fulfill DSM-IV criteria for current PTSD, based on the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) and on the Clinician-Administered PTSD Scale (CAPS).
- CAPS score must be at least 40 (moderate PTSD severity) at screening.
- Current, primary Axis I disorders other than PTSD.
- History or current bipolar disorder or primary psychotic disorders (e.g. schizophrenia, schizoaffective disorder).
- Current diagnosis of anorexia nervosa or bulimia nervosa.
- Women who are pregnant or are breast-feeding.
- Drug or alcohol abuse or dependence within the preceding 3 months.
- poorly controlled hypertension (manifest by SBP > 140 and/or DBP > 90); HR < 60 or > 100 at rest at the time of screening and confirmed immediately prior to randomization
- Evidence of coronary artery disease as evidenced by history, abnormal ECG, typical symptoms
- History of arrhythmia, cardiac surgery, or family history of sudden death
- Hepatic dysfunction as defined by AST and ALT > 2x URL, or alkaline phosphatase and bilirubin > 1.5 x URL within X days prior to randomization
- Chronic renal disease as defined by serum creatinine > 1.9
- Any other serious or unstable clinically significant abnormal findings of laboratory parameters, physical examination, or ECG as determined by the PI.
- Any other serious or unstable condition that would put the subjects at undue risk as determined by the PI or additional safety monitor.
- Serious and imminent suicidal or homicidal risk.
- Psychotropic medication that will not be tapered off at least 7 days prior to screening; withdrawal symptoms must be absent at the time of screening
- History of nasal disorders or sinonasal surgery, or significant nasal abnormalities based on nasal exam.
- Received investigational intervention within 30 days prior to randomization
Study & Design
- Study Type
- INTERVENTIONAL
- Study Design
- CROSSOVER
- Arm && Interventions
Group Intervention Description placebo/NPY Neuropeptide Y This arm gets placebo (saline) first then NPY. NPY/placebo Neuropeptide Y This arm gets NPY first then placebo (saline). The placebo is 0.9% USP-grade saline without NPY.
- Primary Outcome Measures
Name Time Method Patient Rated Inventory of Side Effects (PRISE) baseline and within 2 hours of administration of NPY Clinician-administered and safety measures will take place right before and after the administration to identify and evaluate the tolerability of each possible symptom (from baseline to within 2 hours of NPY administration).
- Secondary Outcome Measures
Name Time Method Change in Beck Anxiety Inventory (BAI) at baseline and within 2 hours of administration of NPY Self-report behavioral measures will take place right before and after the administration to evaluate acute anxiolytic effects of intranasal administration of NPY
State-Trait Anxiety Inventory (STAI) baseline and within 2 hours of administration of NPY Self-report behavioral measures will take place right before and after the administration to evaluate acute anxiolytic effects of intranasal administration of NPY
