  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Male and female outpatients, age 18-75.
  • Diagnosis of Panic Disorder with or without Agoraphobia by DSM-IV criteria
  • MGH Panic Clinical Global Impression of Severity score Score equal to or greater than 4
  • Patients with current major depressive disorder will be allowed if the panic disorder is primary (as determined on interview by clinician and patient), and the baseline MADRS score is less than or equal to 20
  • Willingness and ability to comply with the requirements of the study protocol.

Participants must have discontinued MAOI use at least 14 days prior study baseline. Patients must discontinue regular benzodiazepine or other non-MAOI antidepressant therapy at least one week (5 weeks for fluoxetine) prior to baseline. Concomitant beta-blockers are proscribed unless prescribed for a medical indication (e.g., hypertension, at a stable daily dose for > 1 month).

  • History of hypersensitivity or prior non-response or intolerance of duloxetine.
  • Patients who have failed 4 or more medication trials of at least 4 weeks at adequate dose (e.g. paroxetine 20mg or equivalent). Treatment failure is here defined as clinician judgment based on assessment of patient history of prior treatment of minimal or no reduction in panic attacks, anticipatory anxiety or avoidance during a specific, medication trial.

About this study

The purpose of this study is to determine whether duloxetine is effective in the treatment of panic disorder.

Read the detailed description

Panic Disorder is relatively common, with a lifetime prevalence of 3.5 % (Kessler, et al 1994) and characterized by a typically chronic course (Marzol \& Pollack, 2000). Affected individuals tend to be high utilizers of general health care services, frequently receiving extensive and unrevealing medical work-ups (Katon, 1997); while the panic disorder itself often goes unrecognized (Sartorious, et al 1993). Panic disorder has a significant negative impact on work, family, and social life (Rubin, et al 2000), and is associated with increased rates of negative life events and diminished overall quality of life (Cramer, et al 2005). Research indicates that the quality of life and well-being of patients with panic disorder is similarly or more impaired than that of patients with serious medical illnesses, such as type II diabetes (Rubin, et al 2000).

Treatment of panic disorder is focused on the reduction of panic attacks, avoidance behavior, and anticipatory anxiety, as well as the resolution of comorbid conditions. The overarching goal of panic disorder treatment is reduction in symptoms to allow improvement in overall quality of life (Pollack, 2005).

Duloxetine is a serotonin-norepinephrine reuptake inhibitor (SNRI) that has greater initial noradrenergic effects than venlafaxine (Goldstein, et al 2004). Recent data from a placebo controlled fixed dose study, suggested that venlafaxine at 225 mg/d (a dose at which noradrenergic effects are likely to be relevant), was more efficacious on a number of measures of panic disorder than the SSRI, paroxetine (Pollack, et al 2003). This data, combined with our clinical experience with duloxetine to date, support the assertion that duloxetine is likely to prove an effective agent for panic disorder.

Thus, we propose to perform the first systematic examination of the efficacy of duloxetine for panic disorder in a study in which 15 patients with panic disorder will receive duloxetine flexibly dosed from 30 to 120 mg/d in open treatment for 8 weeks. Information learned in this study will help guide treatment selection for panic disorder by providing initial open efficacy data for duloxetine in panic disorder.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • DuloxetineDrug

    Also called Cymbalta

    Treatment will be initiated at 30mg/day in the first week (week 0), and then increased to 60mg/day at week 1, with the option to increase to 90mg at week 4, and 120mg at week 6.

What is being measured

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

  1. Panic Disorder Severity Scale (PDSS)

    The PDSS contains seven items assessing multiple dimensions of panic disorder severity, including (a) frequency of panic attacks, (b) distress during panic attacks, (c) anticipatory anxiety, (d) agoraphobic fear and avoidance, (e) interoceptive fear and avoidance, (f) impairment of work functioning, and (g) impairment of social functioning. The PDSS ranges from 0 to 28, with higher ratings reflecting greater degrees of symptom severity.

    Measured: 8 weeks

Secondary outcomes (2)
  1. Clinical Global Impression of Severity Scale (CGI-S)

    The CGI-S is a clinician-rated instrument used to assess global severity of symptoms. The CGI-S ranges from 1 (normal, not at all ill) to 7 (among the most extremely ill). Remission was defined strictly as a CGI-S score of 1 or 2 (not at all ill or borderline ill) and zero panic attacks at endpoint.

    Measured: 8 weeks

  2. Panic Attack Scale (PAS)

    The PAS is a measure that assesses participants' total number of panic attacks (situational and unexpected with full and limited symptoms), as well as anticipatory anxiety, since last visit. There is no total score.

    Measured: 8 weeks

A Phase 4 study testing Duloxetine in people with Panic Disorder, run by Massachusetts General Hospital at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 27 Apr 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 Dec 2013). 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?

Panic Disorder Severity Scale (PDSS) (time frame: 8 weeks). 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 NCT00438971, which also lists 10 linked publications.

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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Apr 2016.
