Introduction:
Long-term maintenance treatment is essential in management of bipolar I disorder (BP-I) to achieve mood stability, prevent recurrence of mood episodes and improve functioning. Aripiprazole once-monthly 400 mg (AOM 400) is a long-acting formulation of aripiprazole for maintenance treatment of BP-I. In a double-blind, placebo-controlled, randomized withdrawal study in adult patients with BP-I after a manic episode (NCT01567527), AOM 400 delayed time to and reduced rate of recurrence of mood episodes and was safe and well tolerated (1). In an open-label, long-term safety study (NCT01710709), AOM 400 was safe and effective as long-term maintenance treatment (2).
Objective:To evaluate the effect of long-term AOM 400 maintenance treatment on manic and depressive symptoms in BP-I patients from the open-label, long term safety study.
Methods:Manic and depressive symptoms were assessed post-hoc by analysis of change from study entry in the Young-Mania Rating Scale (YMRS) and Montgomery-Åsberg Depression Rating Scale (MADRS) total scores and line item scores. The mean changes from baseline at last visit in YMRS and MADRS total scores, and single items were calculated using descriptive statistics, using last observation carried forward for total scores and observed cases for single items.
Results:A total of 464 patients entered the maintenance phase: 379 were de novo and 85 were rollover patients who completed the double-blind, placebo-controlled withdrawal study. Overall, 63% (291/464) completed 52 weeks of open-label treatment. Mean YMRS and MADRS total scores were minimally changed from baseline (YMRS: 2.31, endpoint change -0.30; MADRS: 3.23, endpoint change +1.24) across the study in the total population.
Conclusion:Patients entering an open-label safety study with stable manic and depressive symptoms maintained stability in both types of symptoms, as shown by minimal mean changes from baseline in YMRS and MADRS scores, suggesting that treatment with AOM 400 is effective in preventing re-emergence of both manic and depressive symptoms.

Study Objectives
To report functional recovery, symptomatic remission, and sustained symptomatic remission rates after treatment with aripiprazole once-monthly 400mg (AOM 400) administered every 4weeks for up to 52weeks as maintenance treatment in a mixed cohort of AOM 400 naïve (de novo) and experienced adults (rollover) with bipolar I disorder (BP-I).
MethodThis open-label study (NCT01710709) enrolled de novo patients with a diagnosis of BP-I and ≥1 previous manic or mixed episode and rollover patients who completed a randomized, double-blind, placebo-controlled study assessing the efficacy and safety of AOM 400 (NCT01567527). Efficacy was assessed by mean changes from baseline in Young-Mania Rating Scale (YMRS), Montgomery-Asberg Depressive Rating Scale (MADRS), and Clinical Global Impression- Bipolar Version-Severity of Illness (CGI-BP-S) scores. Sustained functional recovery was defined as a total score of ≤11 on the Functioning Assessment Short Test (FAST) for ≥8 consecutive weeks. Remission was defined as YMRS and MADRS total scores ≤12, and sustained remission was defined as meeting criteria for remission for 8 consecutive weeks. The study included a screening phase (6weeks) for de novo patients, an oral aripiprazole conversion phase (4–6weeks), an oral stabilization phase (4–12weeks), and an AOM 400 maintenance phase (up to 52weeks). Rollover patients entered directly into the AOM 400 maintenance phase.
ResultsA total of 464 subjects entered the maintenance phase and 63% (291/464) completed the trial. Of patients entering the maintenance phase, 379 (82%) were de novo and 85 (18%) were rollover. The most frequent reasons for discontinuation were withdrawal of consent (11%) and adverse events (AEs) (10%). Weight increase (1.5%, 7/464) and BP-I (0.9%, 4/464) were the most common reasons for discontinuation due to AEs. Improvements in mean YMRS, MADRS, CGI-BP-S, and FAST scores achieved in previous phases were maintained over 52weeks. Treatment-emergent AEs experienced by >10% of the patients were akathisia (14.7%), weight increased (13.4%), nasopharyngitis (12.1%), and insomnia (11.0%). A high proportion of de novo patients met the criteria for symptomatic remission (87.2%, 328/376) and sustained remission (77%, 292/379) by last visit. Rollover patients’ remission rate remained stable (98.8%, 84/85) by last visit. Of the rollover patients, 35/85 (43%) and 35/116 (36%) of de novo subjects met the criteria for sustained functional recovery after study completion.
ConclusionsPatients treated with AOM 400 maintained symptomatic and functional stability for up to 52weeks. Importantly, more than one-third of patients achieved sustained functional recovery using a strict criterion. Overall, AOM 400 was safe and well tolerated in patients with BP-I. Results support AOM 400 as a viable once-monthlyoption for maintenance treatment of BP-I.
