About this study

Official title: Clinical Evaluation of BRL29060A (Paroxetine Hydrochloride Hydrate) in Posttraumatic Stress Disorder (PTSD) - A Placebo-controlled, Single-Blind Comparative Study -

This is a single-blind, placebo-controlled, parallel group study to evaluate the efficacy of BRL29060A (paroxetine hydrochloride hydrate, hereafter paroxetine) administered orally over the dose range of 20 mg to 50 mg once daily after supper for 12 weeks in Japanese patients with posttraumatic stress disorder (PTSD) as assessed by the change from baseline in CAPS-SX total score. Also the effect of paroxetine on regional cerebral blood flow (rCBF) induced by subthreshold emotional arousing (or symptom stimulating) tasks will be determined using functional magnetic resonance imaging (fMRI) for exploratory assessment of the correlation between the change in rCBF and the efficacy.

The sample size is 30 subjects. The study period consists of 4 weeks of run-in phase, 12 weeks of treatment phase, 0-3 weeks of taper phase and follow-up examination at 2 weeks after the last dose, for a total of 18-21 weeks.

Subjects will visit the clinic at the start of run-in phase, Week -2, the start of treatment phase, Weeks 2, 4, 6, 8 and 12 of treatment, and follow-up examination.

Study groupRoleWhat they receive
paroxetineExperimentalDrug 2 (20 mg/day or placebo) will be administered once daily after supper for the first two weeks after the run-in phase. If the investigator/subinvestigator judges that a sufficient response is achieved, Drug 2 will be continued for the remaining period. If a sufficient response is not achieved with Drug 2 but treatment is well tolerated, the dose will be titrated to one step higher level until a sufficient response is achieved [i.e., Drug 3 (30 mg/day or placebo) → Drug 4 (40 mg/day or placebo) → Drug 5 (50 m/day or placebo)] at intervals of at least two weeks by once daily administration after supper. Once a sufficient response is achieved, that dose will be continued.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With the Indicated Change From Baseline in CAPS-SX (Clinician-Administered Post Traumatic Stress Disorder (PTSD) Scale One Week Symptom Status Version) Total Score at Week 12

    The Clinical-Administered PTSD Scale (CAPS) is a structured interview for assessing PTSD diagnostic status and symptom severity. The CAPS assesses both the frequency and intensity of individual PTSD symptoms on separate five-point (0-4) rating scales, and these ratings can be summed to create a nine-point (0-8) severity score for each symptom. The total CAPS score can range from 0 to 136, with a higher value indicating increased severity. A minus value for change from baseline indicates an improvement of symptom severity.

    Measured: Baseline and Week 12

Secondary outcomes (7)
  1. Number of Participants With the Indicated Week 0 and Week 12 Z-scores for Regional Blood Flow Using Functional Magnetic Resonance Imaging (fMRI) in the Left Amygdala (LA), Right Amygdala (RA), and the Medial Prefrontal Cortex (MPFC)

    Change in regional blood flow (rCBF) measured by fMRI represents altered neuronal responses in PTSD patients and is considered to be the biomarker for treatment response. fMRI measures are provided as blood oxygeneration level-dependent (BOLD) signals (z-score). To trigger neuronal activation, 2 visual stimuli were used: MVA-task (consisting of MVA-related and unpleasant pictures) and face-task (consisting of a variety of facial expressions [e.g., neutral, happy, fear]). Week 0 and 12 rCBF data from 1 participant were invalid (involuntary movement in the fMRI machine); no analysis was done.

    Measured: Baseline and Week 12

  2. Number of Participants With the Indicated Change From Baseline in CAPS-SX (Clinician-Administered Post Traumatic Stress Disorder [PTSD] Scale One Week Symptom Status Version) Total Score at Weeks 4 and 8

    The Clinical-Administered PTSD Scale (CAPS) is a structured interview for assessing PTSD diagnostic status and symptom severity. The CAPS assesses both the frequency and intensity of individual PTSD symptoms on separate five-point (0-4) rating scales, and these ratings can be summed to create a nine-point (0-8) severity score for each symptom. The total CAPS score can range from 0 to 136, with a higher value indicating increased severity. A minus value for change from baseline indicates an improvement of symptom severity.

    Measured: Baseline and Weeks 4 and 8

  3. Number of Participants With the Indicated Change From Baseline in CAPS-SX (Clinician-Administered Post Traumatic Stress Disorder [PTSD] Scale One Week Symptom Status Version) Relating Re-experiencing at Weeks 4, 8, and 12

    The Clinical-Administered PTSD Scale (CAPS) is a structured interview for assessing PTSD diagnostic status and symptom severity. The CAPS assesses both the frequency and intensity of individual PTSD symptoms on separate five-point (0-4) rating scales, and these ratings can be summed to create a nine-point (0-8) severity score for each symptom. The total CAPS score can range from 0 to 136, with a higher value indicating increased severity. A minus value for change from baseline indicates an improvement of symptom severity.

    Measured: Baseline and Weeks 4, 8, and 12

  4. Number of Participants With the Indicated Change From Baseline in CAPS-SX (Clinician-Administered Post Traumatic Stress Disorder [PTSD] Scale One Week Symptom Status Version) Relating Avoidance and Numbing at Weeks 4, 8, and 12

    The Clinical-Administered PTSD Scale (CAPS) is a structured interview for assessing PTSD diagnostic status and symptom severity. The CAPS assesses both the frequency and intensity of individual PTSD symptoms on separate five-point (0-4) rating scales, and these ratings can be summed to create a nine-point (0-8) severity score for each symptom. The total CAPS score can range from 0 to 136, with a higher value indicating increased severity. A minus value for change from baseline indicates an improvement of symptom severity.

    Measured: Baseline and Weeks 4, 8, and 12

  5. Number of Participants With the Indicated Change From Baseline in CAPS-SX (Clinician-Administered Post Traumatic Stress Disorder [PTSD] Scale One Week Symptom Status Version) Relating Increased Arousal Symptom at Weeks 4, 8, and 12

    The Clinical-Administered PTSD Scale (CAPS) is a structured interview for assessing PTSD diagnostic status and symptom severity. The CAPS assesses both the frequency and intensity of individual PTSD symptoms on separate five-point (0-4) rating scales, and these ratings can be summed to create a nine-point (0-8) severity score for each symptom. The total CAPS score can range from 0 to 136, with a higher value indicating increased severity. A minus value for change from baseline indicates an improvement of symptom severity.

    Measured: Baseline and Weeks 4, 8, and 12

  6. Number of Participants With the Indicated Change From Baseline in CGI (Clinical Global Impression) Severity of Illness Scores at Weeks 2, 4, 6, 8, 10, and 12

    The participant's status was assessed using the following 8-point scale: 0, Not assessed; 1, Normal, not at all ill; 2, Borderline mentally ill; 3, Mildly ill; 4, Moderately ill; 5, Markedly ill; 6, Severely ill; 7, Among the most extremely ill patients.

    Measured: Baseline and Weeks 2, 4, 6, 8, 10, and 12

  7. Number of Participants With a Clinical Global Impression (CGI) Global Improvement of 4 at Week 12

    The participant's status was assessed using the following 8-point scale: 0, Not assessed; 1,Very much improved; 2, Much Improved; 3, Minimally improved; 4, No change; 5, Minimally worse; 6, Much worse; 7, Very much worse.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 19 Nov 2009). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of Participants With the Indicated Change From Baseline in CAPS-SX (Clinician-Administered Post Traumatic Stress Disorder (PTSD) Scale One Week Symptom Status Version) Total Score at Week 12 (time frame: Baseline and Week 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00557622, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
