Study Evaluating Desvenlafaxine Succinate Sustained-Release (DVS SR) In The Treatment Of Child And Adolescent Outpatients With Major Depressive Disorder

February 18, 2011 updated by: Wyeth is now a wholly owned subsidiary of Pfizer

Final Report: Multicenter, Open-Label, Safety, Tolerability, And Pharmacokinetic Study To Evaluate Single Ascending Doses And Subsequent Short-Term Administration Of Fixed Doses Of DVS SR Tablets In The Treatment Of Child And Adolescent Outpatients With Major Depressive Disorder

The primary purpose of this study is to test the safety and tolerability of single ascending doses of Desvenlafaxine Succinate Sustained-Release (DVS SR) in both child and adolescent outpatients with major depressive disorder. This study will also characterize the pharmacokinetic profile of DVS SR in children and adolescents with major depressive disorder.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame

Time Frame: Baseline to Follow-up (up to Day 77)
AEs are any untoward, undesired, or unplanned event in the form of signs, symptoms, disease, or laboratory or physiologic observations occurring in a person given study treatment. The event does not need to be causally related to the study treatment. SAEs are adverse events that result in death, are life threatening, require hospitalization or prolongation of hospitalization, result in persistent or significant disability or incapacity, result in cancer, or result in a congenital anomaly or birth defect.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Population Pharmacokinetics Dose Normalized AUC (AUC/D): First Method, Second Method
Time Frame: Day 1, Day 28, and Day 56
Relationship of variables (i.e., age, sex, ethnicity, and food) examined by fitting dose normalized AUC (AUC/D) values to a power model. AUC/D regressed against variables using power equation Y=A*W^b (Y=AUC/D; A=coefficient; W=variable; b=exponent). AUC values from children cohort (ages 7 to 11) combined doses=first method of analysis. AUC from adolescent cohort (ages 12 to 17) combined doses=second method of analysis. AUC values combined from both cohorts=third method of analysis. Measured as nanograms multiplied by hours divided by milliliters per milligram of dose [(ng*hr/mL)/mg of dose].

Population Pharmacokinetics Dose Normalized AUC (AUC/D): Third Method
Time Frame: Day 1, Day 28, and Day 56
Relationship of variables (i.e., age, sex, ethnicity, and food) examined by fitting dose normalized AUC (AUC/D) values to a power model. AUC/D regressed against variables using power equation Y=A*W^b (Y=AUC/D; A=coefficient; W=variable; b=exponent). AUC values from children cohort (ages 7 to 11) combined doses=first method of analysis. AUC from adolescent cohort (ages 12 to 17) combined doses=second method of analysis. AUC values combined from both cohorts=third method of analysis. Measured as nanograms multiplied by hours divided by milliliters per milligram of dose [(ng*hr/mL)/mg of dose].

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.

Time Frame: Baseline, Inpatient Days 1 to 4, Outpatient Days 5 to 7, Outpatient Weeks 2 through 8 and Outpatient Week >8 (or early termination)
CDRS-R total score: scale measures 17 depressive symptoms, of which 3 are rated 1 to 5 and 14 are rated 1 to 7 (1 = no symptom difficulties; 5 or 7 = severe clinically significant difficulties) for a total score range of 17 to 113. Lower total scores indicate lower intensity of symptoms.
