Efficacy and Safety of 3-Week Fixed-Dose Asenapine Treatment in Pediatric Acute Manic or Mixed Episodes Associated With Bipolar I Disorder (Protocol No. P06107)


Efficacy and safety of asenapine for the treatment of bipolar I disorder (manic or mixed
episodes) will be evaluated in participants between 10 and 17 years old, who are either
hospitalized or non-hospitalized. In this 3-weeks, double-blind, parallel design trial,
patients eligible for participation will be randomized to receive one out of three fixed
dose levels of asenapine, or placebo. Trial medication and placebo are provided as
identical-looking sublingual tablets; concurrent use of psychotropics is prohibited, except
use of short-acting benzodiazepines and psychostimulants approved for the treatment of
attention deficit hyperactivity disorder (ADHD). Main treatment effect is measured using the
Young Mania Rating Scale (Y-MRS) and safety is evaluated using the recordings of adverse
events, routine blood panels, physical examinations (including vital signs), and
electrocardiograms. Patients who complete the double blind trial may be offered to continue
(open-label) treatment with asenapine for an extended period of time. Follow-up information
on safety parameters will be collected in all patients within 30 days following treatment
discontinuation.


Participants' scores on the Y-MRS at baseline will be subtracted from those at Day 21 to
determine the amount of change over time with treatment. The responses for the 3 different
asenapine doses compared to placebo will be evaluated. The Y-MRS is an 11 item scale: seven
items ranked on scale from 0 to 4 and four items ranked 0 to 8 with a range of possible
total scores from 0 to 60.

Participants' overall score on the CGI-BP at Day 21 will be evaluated to determine the
amount of change over time with treatment. The responses for the 3 different asenapine doses
compared to placebo will be evaluated. CGI-BP is a single-item clinician-rated scale used to
assess the participant's global improvement compared to their status at baseline. Scores
range from not ill (1) to very severely ill (7).

The proportion of participants whose total Y-MRS score is decreased ≥50% from baseline at
Day 4, 7, 14 and 21. Results for the 3 different asenapine doses compared to placebo will be
evaluated.

The change from baseline at Day 21 in the Y-MRS total score will be compared among the
asenapine dose groups, and for each dose relative to placebo.

Participants' mania sub-score from the CGI-BP will be evaluated for each study visit (Days
4, 7, 14 and 21) to determine the amount of change over time with treatment. The responses
for the 3 different asenapine doses compared to placebo will be evaluated.

Participants' depression sub-score from the CGI-BP will evaluated at each study visit (Days
4, 7, 14 and 21) to determine the amount of change over time with treatment. The responses
for the 3 different asenapine doses compared to placebo will be evaluated.

Participants' CDRS-R at baseline will be subtracted from those at each study visit at which
this rating was measured (Days 7, 14 and 21) to determine the amount of change over time
with treatment. The responses for the 3 different asenapine doses compared to placebo will
be evaluated. The CDRS-R is a 17-item scale that assesses the severity and presence of
depressive symptoms: fourteen items are rated from 1 to 7 and three items are rated from 1
to 5; total scores range from 17 to 113.

Participants' CGAS at baseline will be subtracted from that at the Day 21 visit to determine
the amount of change over time with treatment. The responses for the 3 different asenapine
doses compared to placebo will be evaluated. The CGAS is a 100-point scale, with a possible
range of 1 to 100. Normal social functioning is defined as a CGAS total score of ≥70.

Participants' PQ-LES-Q total score at baseline will be subtracted from that at the Day 21
visit to determine the amount of change over time with treatment. The responses for the 3
different asenapine doses compared to placebo will be evaluated. The PQ-LES-Q is a 15-item
scale, with total score calculated as the sum of the first 14 items, with a range of 14 to
70. Each item is scored by the child from 1 to 5, with higher scores indicative of greater
enjoyment and satisfaction.

Participants' PQ-LES-Q overall score (i.e. item 15) at baseline will be subtracted from that
at the Day 21 visit to determine the amount of change over time with treatment. The
responses for the 3 different asenapine doses compared to placebo will be evaluated. The
PQ-LES-Q overall score is determined by the answer to item 15 on the questionnaire (range: 1
to 5).
