General information about the trial
|
|||
Main objective of the trial |
The primary objective of this study was to evaluate the efficacy of intranasal esketamine 84 milligram (mg) compared with intranasal placebo in addition to comprehensive standard of care in reducing the symptoms of major depressive disorder (MDD), including suicidal ideation, in subjects who are assessed to be at imminent risk for suicide, as measured by the change from baseline on the Montgomery Asberg Depression Rating Scale (MADRS) total score at 24 hours post first dose.
|
||
Protection of trial subjects |
This study was conducted in accordance with the ethical principles that have their origin in the Declaration of Helsinki and that are consistent with Good Clinical Practices and applicable regulatory requirements. Safety was evaluated based on the following variables: Adverse events, Clinical laboratory tests (hematology, serum chemistry, and urinalysis), Vital sign measurements, Physical examinations, electrocardiogram (ECG), Nasal examinations, Suicide Ideation and Behavior Assessment Tool (SIBAT), Dosing day assessments (pulse oximetry, MOAA/S, CADSS).

MADRS is clinician-rated scale designed to measure depression severity, and to detect changes due to antidepressant treatment. Scale consists of 10 items (apparent sadness, reported sadness, inner tension, sleep, appetite, concentration, lassitude, interest level, pessimistic thoughts, and suicidal thoughts), each of which is scored from 0 (item is not present or is normal) to 6 (severe or continuous presence of symptoms), summed for a total possible score of 0 to 60. Higher scores represent more severe condition. A negative change in score indicates improvement. Full efficacy analysis set included all randomized subjects who received at least 1 dose of intranasal study agent during the double-blind phase and have had both a baseline and a postbaseline evaluation for the MADRS total score or Clinical Global Impression –Severity of Suicidality - Revised (CGI-SS-R). Here, N (number of subjects analyzed) signifies number of subjects evaluable for this endpoint.

Change From Baseline in Suicide Ideation and Behavior Assessment Tool (SIBAT) Module 7 – Clinician-rated FoST Total Score During Double-blind Phase | |||||||||||||||||||||||||||||||||||||||
End point description |
SIBAT Module 7 Assessment of frequency of suicidal thinking (FoST) is a clinician-reported global impression with response options of “Never”, “Rarely”, “Sometimes”, “Often”, “Most of the time”, and “All of the time.” The score ranges from 0 to 5. A higher score indicates a more severe condition. Negative change in score indicates improvement. Full efficacy analysis set included all randomized subjects who received at least 1 dose of intranasal study agent during the double-blind phase and have had both a baseline and a post-baseline evaluation for the MADRS total score or CGI-SS-R. Here, 'n' (number analyzed) signifies number of subjects who were evaluable at specified time points.

Date |
Amendment |
||
07 Apr 2017 |
The overall reason for the amendment was to revise based on comments received during an initial Voluntary Harmonisation Procedure (VHP) assessment; the following changes are included: Duration of hospitalization without the need for discussion with the Sponsor updated, A remote contact at Day 35 was added to the Time and Events Schedule, Exclusion criteria were revised to explicitly specify a detailed list of important medical conditions which are exclusionary, Text was added to emphasize that subjects may participate in the study only if they have adequate capacity to give consent and after fully understanding the potential risks, benefits, and potential adverse events of the study. |
||
20 Apr 2017 |
The overall reason for the amendment was to update and/or clarify protocol content based on feedback received during study initiation activities. Exclusion criterion was revised to clarify which potential subjects are excluded from participation in the study due to substance or alcohol use disorder, a positive urine test result; to clarify that subjects who were previously enrolled in this study or the Sponsor’s other studies in this population (54135419SUI3002 and ESKETINSUI2001) are excluded from participation in this study. |
||
08 Feb 2018 |
The overall reason for the amendment was to remove the interim analysis from the 54135419SUI3001 protocol; to clarify that Module 3 Suicide Ideation and Behavior Assessment Tool (SIBAT) was an exploratory objective; to modify the timing of screening procedures to be consistent with the Time and Events Schedule; to clarify which potential subjects were not excluded from participation in the 54135419SUI3001 study due to having a positive screening test for prescribed psychostimulants that are permitted during the study; and updated text regarding the presentation of nasal examination data. |

Interruptions (globally) |
|||
Were there any global interruptions to the trial? No | |||
Limitations and caveats |
|||
Limitations of the trial such as small numbers of subjects analysed or technical problems leading to unreliable data. | |||
Esketamine has known effects that may impact blinding, these treatment-emergent events potentially could have biased research staff. To minimize this bias, protocol specified that different raters perform efficacy, safety assessments. |
