Evaluation of GSK561679 in Women With Post-Traumatic Stress Disorder

Completed · Phase 2 · Has a placebo group

Conditions studied: Stress Disorders, Post-Traumatic

In brief

This study will test the hypothesis of whether an antagonist at the corticotropin releasing factor type 1 (CRF1) receptor (i.e. GSK561679) is superior to placebo in reducing symptoms of post-traumatic stress disorder (PTSD).

• Subject is currently participating in another clinical trial in which she is or will be exposed to an investigational or non-investigational drug or device, or has done so within the preceding month for studies unrelated to PTSD, or 1 month for studies related to PTSD
• Current evidence or history of significant unstable medical illness or organic brain impairment, including stroke, central nervous system (CNS) tumor, demyelinating disease, cardiac, pulmonary, gastrointestinal, renal or hepatic impairment that would likely interfere with the action, absorption, distribution, metabolism, or excretion of GSK561679.
• Patients who in the investigator's judgment pose a current suicidal or homicidal risk
• DSM-IV substance abuse or dependence within the past 90 days. Subject has a positive test for illegal substances.
• Diagnosis of anorexia nervosa or bulimia in the past year.
• Subject has a documented history of hepato-biliary disease including a history of, or positive laboratory results for hepatitis (hepatitis B surface antigen and/or hepatitis C antibody), and/or clinically significant hepatic enzyme elevation including any one of the following enzymes greater than 1.5 times the upper limit of normal (ULN) value (alanine transaminase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total or direct bilirubin > 1.5 x ULN, unless consistent with presumed or diagnosed Gilbert's disease)
• Subject has taken systemic corticosteroids within 2 weeks of the Randomization Visit
• Treatment with any other psychoactive medication within 2 weeks of Visit 1, including all antidepressants, psychoactive herbal or nutritional treatment (St Johns Wort, SAM-e), lithium, other mood stabilizers, oral antipsychotics, depot antipsychotics within 12 weeks, beta blockers, thioridazine, pimozide, opiates, anxiolytics, and sedatives (with the exception of zolpidem, eszopiclone, and zaleplon). Also any treatment with any medication that the PI judges not acceptable for this study.
• Subject who is likely to require the use of the following medications: Chronic (for more than 2 weeks), regular nonsteroidal anti-inflammatory drugs (NSAID) use. Any use of aspirin (including low dose)
• Subject has taken non-psychoactive (prescription or non-prescription), dietary, or herbal products, with a narrow therapeutic index, that are metabolized via the cytochrome P450 3A4 or 2C9 pathway (warfarin), or transported via OATP1B1 or P-gp, within 2 weeks (or 5 half-lives, whichever is longer) prior to the Randomization Visit.
• Subject has taken other (non-psychoactive) prescription, non-prescription, dietary, or herbal products that are potent inducers or inhibitors of the cytochrome P450 3A4 pathway for 2 weeks (or 5 half lives, whichever is longer) prior to the Randomization Visit.
• Subject has a stool positive for occult blood.
• Pregnancy or lactation
• Subjects who, in the opinion of the investigator, would be non compliant with the visit schedule or study procedures (e.g. illiteracy, planned vacations, or planned hospitalizations during the study).
• Previous treatment with CRF1 receptor antagonist
• Any laboratory abnormality that in the investigator's judgment is considered to be clinically significant (blood pressure, electrocardiogram (ECG), thyroid stimulating hormone (TSH), liver function test (LFT), etc.)
• Patients who are receiving exposure-based psychotherapy that targets PTSD symptoms
• Current or planned litigation or other actions related to secondary gain regarding the traumatic event
• Subject has clinical evidence of, or ECG results indicating any of the following at either screen or Randomization Visit unless repeat ECG shows that the parameter had returned to within normal range by the Randomization Visit:
• Corrected QT Interval (QTc) > 450 msec;
• any cardiac condition or ECG evidence that the investigator feels may predispose the subject to ischemia or arrhythmia; or
• any ECG abnormality that, in the investigator's judgment, may pose a potential safety concern
