Clinician-rated interview-based scale (with both child and parent or guardian) to assess 17 distinct symptom areas to derive an index of depression severity. Discrepancies between informants' responses were resolved by using most impaired rating given by valid informant. Rated on a 7-point scale; range from 1 (no impairment) to 7 (indicates greater impairment). Total score calculated as sum of the 17 items (range 1 to 119); higher score indicates greater impairment. Adjusted mean presented.

Time to relapse analyzed using log-rank test; defined as Hamilton Psychiatric Scale for Depression-17 item score ≥16 at any time during DB phase, discontinuation for unsatisfactory response or efficacy (need for additional or alternate treatment for depression, investigator decision to remove participant for efficacy reasons, or failure to return if investigator determined related to efficacy), hospitalization for depression, suicide attempt, or suicide. Participants who relapsed after DB day 185 or completed DB therapy without relapse were considered as censored on DB day 185 (study day 325).
HAM-D17: a standardized, clinician-administered rating scale that assesses 17 items characteristically associated with major depression. Items are scored on either a 3 point (0 to 2) or a 5 point scale (0 to 4), with 0=none/absent and 4=most severe, for a maximum total score of 50.
HAM-D17 is a standardized, clinician-administered rating scale that assesses 17 items characteristically associated with major depression. Items are scored on either a 3-point (0 to 2) or a 5-point scale (0 to 4) with 0=none/absent and 4=most severe, for a maximum total score of 50. Higher scores indicate greater severity. FOT evaluation is defined as the last "on-therapy" evaluation, regardless of the number of days on therapy. Analysis on Observed cases (non-missing data) and Last observation carried forward (LOCF); LOCF method of imputation for any missing value at any visit.
Any untoward medical occurrence in a participant who received study treatment was considered an AE without regard to possibility of causal relationship. An AE resulting in any of the following outcomes, or deemed to be significant for any other reason, was considered to be an SAE: death; initial or prolonged inpatient hospitalization; a life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; or congenital anomaly.
HAM-D, clinician-rated interview, measures presence of depressive symptoms in 17 areas (symptoms such as depressed mood, guilt feelings, suicide, sleep disturbances, anxiety levels and weight loss). Total score ranges from 0 to 52; higher scores indicate more depression. Change from baseline: mean at observation minus mean at baseline.

Nausea by spontaneous reports to the investigators was counted if it was reported during first 2 weeks of treatment, and it was not seen before the first dose of treatment, or if it was seen before the first dose and the symptoms got worse. If multiple incidences occurred on the same participant during the 2 weeks, only 1 incidence was counted.
DESS: a clinician-administered 43-item assessment that evaluates discontinuation-emergent symptoms resulting from the withdrawal from test article. The DESS total score is the sum of the number of "new symptoms" and "old (but worse) symptoms" (1) and 0 for "old and unchanged symptom", "absent", or "old symptom but improved" for a total possible range of 0 to 43. A higher score indicates more symptoms.

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.
C-SSRS is a participant rated questionnaire to assess suicidal ideation, suicidal behavior, actual attempts (yes or no responses), and intensity of ideation (rated 1=low severity to 5=high severity). Yes/No responses are mapped to Columbia Classification Algorithm of Suicide Assessment (C-CASA) categories: Completed suicide, suicide attempt, preparatory acts toward imminent suicidal behavior, suicidal ideation, and self-injurious behavior, or no suicidal intent. A participant could have a yes or no response in more than one category.
Noncompartmental pharmacokinetic (PK) parameter obtained using 0 to 72 hour concentration data from venous blood samples measured as nanograms per milliliter (ng/mL).
Noncompartmental PK parameter obtained using 0 to 72 hour concentration data from venous blood samples measured as hours (hr).
Plasma decay half-life is the time measured for the plasma concentration to decrease by one half. Noncompartmental PK parameter obtained using 0 to 72 hour concentration data from venous blood samples measured as hours (hr).
AUC (0-∞) = Area under the plasma concentration versus time curve from time zero (pre-dose) to infinity. Noncompartmental PK parameter obtained using 0 to 72 hour concentration data from venous blood samples measured as nanograms multiplied by hours divided by milliliters (ng\*hr/mL).
Area under the plasma concentration versus time curve from time zero (pre-dose) to 48 hours post dose; measured as nanograms multiplied by hours divided by milliliters (ng\*hr/mL).
Cmax measured as nanograms divided by milliliters (ng/mL).

Desvenlafaxine sustained release is used to treat major depressive disorder and is also being studied in fibromyalgia and menopause-related symptoms. It is a small molecule antidepressant developed by Pfizer. The sustained-release formulation is designed to release the drug gradually after oral dosing.
Desvenlafaxine sustained release targets SLC6A2 and SLC6A4, the norepinephrine and serotonin transporters. It acts as an inhibitor of these transporters, which increases norepinephrine and serotonin signaling in the brain. This dual transporter inhibition underlies its antidepressant activity.
Pfizer, Inc. develops desvenlafaxine sustained release. Pfizer trades on the New York Stock Exchange under the ticker PFE. The company has run the clinical development program for this sustained-release formulation across major depressive disorder and other indications.
Desvenlafaxine sustained release is in Phase 3 clinical development. It is an investigational asset, and the completed trials include Phase 3 studies in major depressive disorder. Ten trials are registered for this formulation, all of which are completed, with no active trials currently listed.
Registered trials include NCT00887224, a Phase 3 relapse prevention study in adults with major depressive disorder, and NCT01372150 and NCT01371734, Phase 3 studies in children and adolescents with major depressive disorder. NCT01190514 was a Phase 1 bioequivalence and food effect study. All are completed.
Yes. Desvenlafaxine sustained release is also known as desvenlafaxine succinate sustained release, often abbreviated DVS SR. Other names include desvenlafaxine succinate sustained-release tablets and desvenlafaxine sustained-release. These names refer to the same sustained-release oral formulation developed by Pfizer.
