Trial summary

Introduction and Purpose: Most of the guidelines for the treatment of major depression recommend the use of antidepressants for 4 to 8 weeks. On the other hand, it has been recently reported that they start to show their antidepressant efficacy within a couple of weeks (1,2), contrary to the conventional theory. Read more about this study

About this study

Official title: Prospective 24-week Study, Comparing Clinical Outcomes Between Switching Antidepressants and Maintaining the Same Antidepressant in Patients With Major Depressive Disorder Who do Not Show a 20% Reduction in Symptoms at Week 2

Introduction and Purpose:

Most of the guidelines for the treatment of major depression recommend the use of antidepressants for 4 to 8 weeks. On the other hand, it has been recently reported that they start to show their antidepressant efficacy within a couple of weeks (1,2), contrary to the conventional theory. In addition, a good response (i.e. a 20% reduction in the Montgomery-Åsberg Depression Rating Scale [MADRS]) at week 2 is proposed to be a predictor of subsequent remission at week 6 (3,4), while nonresponse at week 2 could predict unfavourable outcome at week 8 (5). Furthermore, early worsening is suggested to be related to a low rate of remission at weeks 8 and 12(6).

Read the detailed description

To the researchers' knowledge, there is no report to prospectively examine the benefits of switching antidepressants following early nonresponse. In this prospective 24-week study, the researchers will compare clinical outcomes between switching antidepressants and maintaining the same antidepressant in patients with major depressive disorder who do not show a 20% reduction in symptoms at week 2.

Materials and Methods: This open-label 24-week randomized controlled trial will be performed at psychiatric hospitals in Tokyo, Japan.

This study will be conducted with the approval of the Institutional Review Board of each participating hospital, and written informed consent will be obtained from all of the participants after providing a full explanation about the study.

In the short-term acute phase, sertraline will be initiated at 25 mg, increased to 50 mg on day 3, and maintained until day 14. If patients show an early response (i.e. ≧ 20% improvement in the MADRS total score from baseline), sertraline will be continued and titrated at 50 - 100 mg based on clinical judgment. On the other hand, if patients show no early response, they will be randomly divided into two groups. In one group, sertraline will be continued and titrated at 50 - 100 mg, whereas in the other group sertraline will be switched to paroxetine. Paroxetine will be started at 10 mg on days 15 and 16, increased to 20 mg on day 17, and further increased weekly by 10 mg from week 4 (i.e. day 22), while sertraline will be tapered by 25 mg each on days 15 and 16. In case patients are intolerant to adverse events, or they achieve remission (i.e. the MADRS total score ≦ 8), increasing the dose will be terminated. Lorazepam, lormetazepam, and mosapride will be allowed on a p.r.n. basis.

In the long-term follow-up phase after week 8, patients who achieve remission or response will be followed up and the same dose will be administered throughout. Assessments will include the MADRS, the clinical global impression scale (CGI), and the Quick Inventory of Depressive Symptomatology self-reported (QIDS-SR) (weeks 1, 2, 3, 4, 6, 8, 12, 16, 20, and 24). Adverse events will also be monitored on every visit.

What participants receive

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

  • Sertraline to ParoxetineDrug

    For subjects enrolled in this arm, sertraline will be initiated at 25mg, increased to 50mg on day 3, and maintained until day 14. If subjects show an early response (i.e. a 20% improvement in the MADRS total score from baseline) at week 2, sertraline will be continued and titrated at 50 - 100mg based on clinical judgment. On the other hand, if subjects fail to show an early response at week 2, they will be randomly divided into two groups. In one group, sertraline will be continued and titrated at 50 - 100mg, whereas in the other group sertraline will be switched to paroxetine. In this switching group, paroxetine will be started at 10mg on days 15 and 16, increased to 20mg on day 17, and further increased to 40mg by a weekly 10mg increase, while sertraline will be dosed at 25mg on day 15 and terminated on day 16.

  • Paroxetine to SertralineDrug

    Paroxetine will be initiated at 10mg, increased to 20mg on day 3, and maintained until day 14. If subjects show an early response (i.e. a 20% improvement in the MADRS total score from baseline) at week 2, paroxetine will be continued and titrated at 20 - 40mg based on clinical judgment. On the other hand, if subjects fail to show an early response at week 2, they will be randomly divided into two groups. In one group, paroxetine will be continued and titrated at 20 - 40mg, whereas in the other group paroxetine will be switched to sertraline. In this switching group, sertraline will be started at 25mg on days 15 and 16, increased to 50mg on day 17, and further increased to 100mg by a weekly 25mg increase, while paroxetine will be dosed at 10mg on day 15 and terminated on day 16.

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 3 inclusion and 4 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: status not confirmed, as of the sponsor's last update on 28 Sep 2009. 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 Japan. 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?

Results are not available in the source record.

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

Contact Shinichiro Nakajima, M.D. (008139242450, shinichiro_nakajima@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The Montgomery-Asberg Depression Rating Scale (time frame: at weeks1, 2, 3, 4, 6, 8, 12, 16, 20, 24 and 48 - 52.). 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 NCT00519012, which also lists 6 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 28 Sep 2009.
