| Study Type: | Interventional |
|---|---|
| Study Design: | Randomized, Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Placebo Control, Parallel Assignment |
| Condition: |
Major Depressive Disorder |
| Interventions: |
Drug: Escitalopram Drug: Placebo |
Participant Flow
| Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations |
|---|
| Recruitment period was from April 1, 2005 through March, 2007 at 40 centers in the US. |
| Significant events and approaches for the overall study following participant enrollment, but prior to group assignment |
|---|
| 2 week screening with one-week single-blind placebo. Patients meeting selection criteria at baseline were randomized to once daily escitalopram 10-20mg/day or placebo (1:1). |
| Description | |
|---|---|
| Escitalopram | Once daily oral administration of escitalopram tablets - 1 tablet (10mg) for the first three weeks, then 1 tablet (10mg or 20mg) depending on therapeutic response and tolerability. |
| Placebo | Once daily oral administration of placebo tablets |
| Escitalopram | Placebo | |

Outcome Measures
| 1. Primary: | Change in Children's Depression Rating Scale - Revised (CDRS-R) Total Score [ Baseline to end of week 8 ] |
Hide Outcome Measure 1| Measure Type | Primary |
|---|---|
| Measure Title | Change in Children's Depression Rating Scale - Revised (CDRS-R) Total Score |
| Measure Description | Change from baseline to week 8 in Children's Depression Rating Scale total score. The scale measures 17 depressive symptoms, of which 3 are rated 1-5 and 14 are rated 1-7 (1 = no symptom difficulties; 5 or 7 = severe clinically significant difficulties) for a total score range of 17-113. |
| Time Frame | Baseline to end of week 8 |
| Safety Issue | No |
| Explanation of how the number of participants for analysis was determined. Includes whether analysis was per protocol, intention to treat, or another method. Also provides relevant details such as imputation technique, as appropriate. |
|---|
| Efficacy analyses used Intent-To-Treat Population, which consisted of all patients who received at least 1 dose of double-blind study drug & who had at least 1 post-baseline assessment of the CDRS-R. LOCF technique was used to impute missing data. 1 escitalopram pt. did not have a post-baseline CDRS-R total score. |
| Description | |
|---|---|
| Escitalopram | Once daily oral administration of escitalopram tablets - 1 tablet (10mg) for the first three weeks, then 1 tablet (10mg or 20mg) depending on therapeutic response and tolerability. |
| Placebo | Once daily oral administration of placebo tablets |
| Escitalopram | Placebo | |

Change in Children's Depression Rating Scale - Revised (CDRS-R) Total Score
[units: Change in total score at endpoint] Mean ± Standard Error |
-22.4 ± 1.1 | -18.4 ± 1.1 |
| Groups [1] | All groups |
|---|---|
| Method [2] | ANCOVA |
| P Value [3] | 0.022 |
| Least Square Means Difference [4] | -3.4 |
| Standard Error of the mean | ± 1.458 |
| 95% Confidence Interval | ( -6.2 to -0.5 ) |
| [1] | Additional details about the analysis, such as null hypothesis and power calculation: |
|---|---|
| The null hypothesis is that there is no difference in the Change from Baseline to Week 8 in CDRS-R total score between treatment groups. The power calculation was based on the change from baseline to Week 8 in CDRS-R total score (LOCF approach). Assuming an effect size (treatment group difference relative to standard deviation) of 0.325, a sample size of approximately 150 patients per treatment group was used to provide at least 80% power at a significance level of 0.05 using a two-sided test. | |
| [2] | Other relevant information, such as adjustments or degrees of freedom: |
| The model included study center and treatment as factors and baseline core as covariate | |
| [3] | Additional information, such as whether or not the p-value is adjusted for multiple comparisons and the a priori threshold for statistical significance: |
| Two-sided at 5% level of significance p < 0.05 considered significant | |
| [4] | Other relevant estimation information: |
| Differences are Escitalopram-Placebo |
| 2. Secondary: | Clinical Global Impressions - Improvement [ At end of weeks 1-8 ] |
| 3. Other Pre-specified: | Children's Global Assessment Scale [ At baseline and end of week 8 ] |
More Information

| There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed. | ||||||
The agreement is:
|
| Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data |
