Aripiprazole Augmentation of SSRI Therapy in Treatment Refractory Depression

24 ottobre 2012 aggiornato da: Prabha Sunderajan, University of Texas Southwestern Medical Center

Aripiprazole Augmentation of SSRI Antidepressant Therapy in Treatment Refractory Depression: Assessment of Symptom Reduction, Psychosocial Function, and Cognitive Function

Our target population will have been adequately treated with one of three selective serotonin reuptake inhibitors (SSRIs; escitalopram, citalopram, or sertraline) for at least 8-12 weeks and continue to experience symptoms of depression that have prompted them to seek additional treatment. Escitalopram, citalopram, and sertraline were selected for use in this study because they are among the most commonly selected SSRIs and they are associated with a reduced likelihood of drug-drug interactions with aripiprazole. After completion of the screening process, eligible participants will be augmented with aripiprazole (5, 10, or 15 mg) for 6 weeks. Participants will continue SSRI treatment with their prescribing physician, in conjunction with study participation. Symptom severity will be assessed on a weekly basis, and cognitive and psychosocial function will be assessed at pre- and post-augmentation. We hypothesize that aripiprazole augmentation will be associated with reductions in symptom severity, and with improved performance on measures of psychosocial and cognitive function.

  • Presence of other primary psychiatric disorders or conditions (including depression due to medical conditions, currently suicidal or high suicide risk, current or past psychotic disorders of any type, bipolar disorder (I, II, or Not Otherwise Specified [NOS]), schizophrenia, schizoaffective disorder, anorexia, bulimia, obsessive compulsive disorder, alcohol or substance abuse or dependence within the last 6 months)
  • Presence of organic brain injury or dementia, based on a cutoff score of < 20 on the Mini Mental Status Examination (MMSE).
  • Concomitant pharmacological or psychotherapeutic treatment (in addition to one SSRI as described in Inclusion Criteria) including but not limited to anxiolytics, neuroleptics, mood stabilizers

Cosa sta misurando lo studio?

Misure di risultato primarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Stockings of Cambridge (SOC) Mean Initial Thinking Time for 3-move Problems
Lasso di tempo: baseline and 6 weeks
The SOC is part of the CAmbridge Neuropsychological Test Automated Battery (CANTAB) and is an executive function task based on the Tower of London test that assesses spatial planning for problems with 2, 3, 4, or 5 moves. The Mean Initial Thinking Time for 3-move problems is the time (in milliseconds)taken to plan a problem solution for trials requiring 3 moves. Higher numbers indicate poorer performance. Time reported is the difference between baseline and 6 weeks post-treatment.

The SOC is part of the CAmbridge Neuropsychological Test Automated Battery (CANTAB) and is an executive function task based on the Tower of London test that assesses spatial planning for problems with 2, 3, 4, or 5 moves.

baseline and 6 weeks
Spatial Working Memory (SWM) Between Errors for 6-move Problems
Lasso di tempo: baseline and 6 weeks
The SWM task is part of the CANTAB neruopsychological test battery and is an executive function task assessing retention and manipulation of items in working memory, with the ability for assessment of perseverative (redundant) errors. Between errors are times the subject revisits a box in which a token was previously found; errors are calculated for 4-, 6-, and 8-box trials. Higher numbers indicate poorer performance. Errors reported are the difference between baseline and 6 weeks post-treatment.
baseline and 6 weeks
Spatial Working Memory (SWM) Strategy Score
Lasso di tempo: baseline and 6 weeks
The SWM task is part of the CANTAB neruopsychological test battery and is an executive function task assessing retention and manipulation of items in working memory, with the ability for assessment of perseverative (redundant) errors. The Strategy score represents the number of times a participant begins a search with the same box for 6- and 8-box problems. Minimum score is 8 and maximum score is 56. Higher numbers indicate poorer performance. Score reported is the difference between baseline and 6 weeks post-treatment.
baseline and 6 weeks

Misure di risultato secondarie

Misura del risultato
Misura Descrizione
Lasso di tempo
Quality of Life Enjoyment and Satisfaction Questionnaire
Lasso di tempo: 6 weeks
The Q-LES-Q general activities is designed to measure subjective satisfaction and enjoyment, as opposed to function, in various domains including physical health, feelings, work, household duties, school/course work, leisure time activities, social relations, and general activities. The raw score is converted into a percent of the maximum possible score and range from 0 to 100. Higher scores indicate greater enjoyment and satisfaction.
6 weeks
Change in Hamilton Rating Scale for Depression (HRSD - 17-item)
Lasso di tempo: 6 weeks
The HRSD 17-item scale is a clinician-administered rating scale designed to assess the severity of symptoms in patients diagnosed with depression. Scores range from 0 to 52, with higher scores indicating higher levels of depression severity.
