P02-36 - Effect of aripiprazole adjunctive to antidepressants on sexual functioning: A subgroup analysis of a 52-week open-label safety study (CN138–164)
This presentation addresses impacts of adjunctive aripiprazole (AA) in major depressive disorder (MDD).
Assess impacts of long-term (≤52 weeks) open-label AA to ADT on efficacy, sexual function and weight change in MDD.
Data were analyzed post-hoc from de novo patients enrolled in an open-label safety study of AA after inadequate response to one or more ADT. Three ADT classes were included: SSRIs, SNRIs, and a noradrenaline-dopamine reuptake inhibitor, bupropion.
Global well-being with AA was assessed (mean change in CGI-S score from baseline by ADT). Sexual functioning was assessed by Sexual Function Inventory (SFI) items: interest in sex, sexual arousal, achievement of orgasm, erection maintenance and sexual satisfaction. Item 6 captured change in the overall improvement score. Weight change at Week 52 (last observation carried forward) was assessed.
Overall mean change in CGI-S (n = 285) by Week 52 was -1.5. Mean changes in CGI-S from baseline scores (4.2-4.4) were: escitalopram (n=64) -1.5, venlafaxine XL (n = 48) -1.4, sertraline (n = 39) -1.7, fluoxetine (n = 41) -1.3, paroxetine or CR (n = 37) -1.5 and bupropion XL or SR (n = 46) -1.4. Improvements on SFI items (n = 155) ranged from -0.2 (sexual satisfaction) to -0.6 (interest in sex and orgasm). Mean overall improvement score (3.8) indicated mild-to-moderate sexual dysfunction. All AA groups experienced a mean weight increase (range +1.8 kg [sertraline] to +3.3 kg [fluoxetine]).
AA moderately improved CGI-S scores (to a similar degree) when added to three different classes of ADTs. Sexual functioning in patients on ADT modestly improved after adding aripiprazole to ADT.
