About this study

Recently, there are increasing data about intensity dependent amplitude change (IDAP: N100 amplitude slope) of auditory evoked Event Related Potential (ERP) components for its role on surrogate marker of central serotonergic activity. A high N100 amplitude slope reflects low serotonergic neurotransmission and vice versa. There are a couple of studies reporting associations of N1 amplitude slope with response to Citalopram (positive correlation) and Reboxetine (negative correlation) treatment in major depressive disorder patients (2,3). The investigator also published a case series about SSRI super-sensitivity and SSRI induced mania in patients with aberrantly high N100 slope (4). And serotonin transporter gene polymorphism was studied for its role about pathophysiology of bipolar disorder (5, 6, 7). Serotonin promoter gene was known to have significant relationship with N100 amplitude slope (8). Furthermore previous study showed that N100 amplitude slope was well correlated with hypomanic and hyperthymic personality (9).

Conclusively from above results, the investigator hypothesized that if depressive patients show aberrant high or low N100 amplitude slope (N100 response outliers), they will not response well to SSRI medication. They will response better to quetiapine XR adjunctive therapy. In this study, the investigator will confirm it by comparing treatment effect between SSRI monotherapy and quetiapine XR adjunctive in aberrant N100 responder.

Hypothesis First visit depressive patients might have monopolar or bipolar depression. If depressive patients show aberrantly high or low N100 amplitude slope, they will not response to SSRI medication.

Patients who have aberrantly high or low N100 amplitude slope will response better to quetiapine XR adjunctive therapy.

1.2 Rationale for this study The development of better strategy for treatment of major depressive disorder and other mood disorder is a very important issue for patients, mental health provider and government. So far, treatments of depressive illness have been based on mainly trial and error method and physician's personal experiences.

So the development of new strategy for predicting better treatment response group of quetiapine XR would be great contributions for basic brain science and mental health fields.

  1. STUDY OBJECTIVES

2.1 Primary objective

Primary target of this study is to prove the following hypothesis :

Patients who have aberrantly high or low N100 amplitude slope will response better to quetiapine XR adjunctive therapy.

2.2 Secondary objectives

Patients who have aberrantly high or low N100 amplitude slope will show higher dropout rate for SSRI monotherapy compared to quetiapine XR adjunctive.

  1. STUDY PLAN AND PROCEDURES

3.1 Overall study design and study plan

This study will be conducted by open, randomized, two armed, and observational phase IV study. The investigator will compare treatment response between Quetiapine XR and SSRIs to major depressive disorder patients showing aberrant response of N100 amplitude slope. The investigator will use SSRIs drugs (paxil CR, es-citalopram, fluoxetine, sertraline) as comparator drug. The investigator will recruit drug naive patients but if there were previous antidepressant medication, washout periods will be required for one week. This study will be conducted as single centre study, and patients will be enrolled based on the DSM-IV major depressive disorder criteria, and also aberrant response of N100 amplitude (N100 slope < 0.21, or > 1.59, this criteria can be revised base on our newly published data). In and out-patients status of patients will recruited together. The treatment duration will be six weeks from beginning of pharmacological treatment.

Procedure for measuring the LDAEP (N100 amplitude slope)

Recording took place in an electrically shielded and sound attenuated room adjacent to the recording apparatus (Synamps, Neuroscan ®). Subjects were seated with open eyes in a slightly reclined chair with a head rest. Evoked responses were recorded with 32 electrodes referred to Cz. Pure sinus tones (1000 Hz, 80 ms duration with 10 ms rise and 10 ms fall time, ISI randomized between 500 and 900 ms) of 5 intensities (55, 65, 75, 85, 95 dB sound pressure level) were presented binaurally in a pseudo-randomised form by audiometry headphones. Data were collected with a sampling rate of 1000 Hz and an analogous bandpass filter (1-30 Hz). Analysis was performed with the Scan® software package version 4.3. One hundred ms prestimulus and 300 ms poststimulus periods were evaluated for about 100 sweeps of every intensity (all together 500 sweeps). For artifact suppression, all trials were automatically excluded from averaging, if the voltage exceeded ± 70uV in any one of the 32 channels at any time point of the averaging period. For each subject, the remaining sweeps were averaged separately for the five stimulus intensities. At least 30 artefact-free sweeps/intensity had to be averaged. N1 peaks (80-140 ms) and P2 peaks (100-250 ms) were determined semi-automatically at the Cz electrode (referred to linked-mastoids). The IDAP was calculated as linear regression slope with stimulus intensity as independent and N1/P2 amplitude as dependent variable.

Seroquel XR adjunctiveExperimentalThe quetiapine XR adjunct group will be titrated up to 300mg. Initial dosing will begin at 50mg on Day 1 and 2, increased to 150mg on Day 3 and 4. Further adjustments will be able to be made upwards or downwards within the recommended dose range of 50mg to 300mg depending upon the clinical response and tolerance of the patient. Seroquel XR will be administered daily in the evening. The dosage of SSRIs will be maintained as low (es-citalopram 5mg, paxil CR 6.25mg, fluoxetine 10mg, and sertraline 25mg).

Who may be eligible to take part?

The sponsor lists 5 inclusion and 25 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 1 Nov 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in South Korea. 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?

Results are not available in the source record.

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

Contact Jung In Kim, Mr (82-31-910-7776, p5p52@hanmail.net), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change from baseline in HDRS scale (time frame: 0,1,2,4,6 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 1 Nov 2012.
