Trial Outcomes & Findings for 12 Week Study of the Safety/Efficacy of Asenapine When Added to Lithium/Valproate in the Treatment of Bipolar Disorder (A7501008 / P05844 / MK-8274-017) (NCT NCT00145470)

NCT ID: NCT00145470

Last Updated: 2024-05-21

Results Overview

The least squares mean change from baseline in Y-MRS score at day 21 was assessed. The Y-MRS is a clinician-rated instrument used for assessing the symptoms of mania, composed of 11 items. For the 11 items, scores range from 0 (symptoms absent) to, depending on the item, either 4 (7 items) or 8 (4 items). Scores for individual items add to a total score (range: 0-60), with higher scores indicating greater symptom severity. Further, decreases in symptom severity over time would be reflected by negative changes from baseline. For evaluation of this endpoint, a last observation carried forward (LOCF) analysis was used; baseline values are not eligible to be carried forward to missing post-baseline assessments.

PRIMARY outcome

Timeframe: Baseline and Day 21

Population: Includes all randomized participants receiving ≥1 dose of study treatment, having ≥1 post-dose Y-MRS assessment.

The least squares mean change from baseline in Y-MRS score at day 21 was assessed. The Y-MRS is a clinician-rated instrument used for assessing the symptoms of mania, composed of 11 items. For the 11 items, scores range from 0 (symptoms absent) to, depending on the item, either 4 (7 items) or 8 (4 items). Scores for individual items add to a total score (range: 0-60), with higher scores indicating greater symptom severity. Further, decreases in symptom severity over time would be reflected by negative changes from baseline. For evaluation of this endpoint, a last observation carried forward (LOCF) analysis was used; baseline values are not eligible to be carried forward to missing post-baseline assessments.

The least squares mean change from baseline in MADRS score at day 84 was assessed. The MARDS is a clinician-rated scale for assessing the severity of symptoms of depression, composed of 10 items. For the 10 items, scores range from 0 (symptoms absent) to 6 (severe). Scores for individual items add to a total score (range: 0-60), with higher scores indicating greater severity of depression. Further, decreases in depression severity over time would be reflected by negative changes from baseline. For evaluation of this endpoint, a LOCF analysis was used; baseline values are not eligible to be carried forward to missing post-baseline assessments.

For Baseline / Change from Baseline data, includes only participants of the overall analysis population with an observation at the time indicated for the respective endpoint.

The least squares mean change from baseline in PANSS score at day 21 was assessed. The PANSS assesses the severity of schizophrenia symptoms through a clinician-rated inventory of 30 items organized in 3 subscales: 1) positive subscale (7 items); 2) negative subscale (7 items); and 3) general psychopathology subscale (16 items). For each item, symptoms are scored from 1 (absent) to 7 (extreme) and add to a total PANSS score (range: 30-210). Higher scores reflect more severe symptoms of schizophrenia. Further, decreases in symptom severity over time would be reflected by negative changes from baseline. For evaluation of this endpoint, a LOCF analysis was used; baseline values are not eligible to be carried forward to missing post-baseline assessments.

Timeframe: Day 84

Population: Per protocol, the analysis population for this endpoint includes all randomized participants receiving ≥1 dose of study treatment, with ≥1 post-dose Y-MRS assessment.

The percentage of participants determined to be ready to discharge at day 84 was estimated (Kaplan-Meier), using the readiness to discharge questionnaire (RDQ). The RDQ is clinician-rated scale to assess readiness for discharge, composed of 7 items. Of the 7 items, only the first 5 items were utilized: 1. Not actively suicidal/homicidal; 2. Adequate control over aggression and impulsivity; 3. Able to carry out basic activities of daily life; 4. Able to take medicine independently; and 5. Delusions and hallucinations do not significantly interfere with functioning. For the 5 items, the clinician provided a response (Strongly Disagree; Disagree; Agree; or Strongly Agree) at each pre-specified visit. The first visit at which the responses to the first 5 items on the RDQ are "Strongly Agree" or "Agree," was defined as the point a participant was ready to discharge.

Participants received asenapine as a fast-dissolving SL tablet, BID. On Day 1, participants received asenapine 5 mg, BID. On Days 2 to 84, asenapine was dosed flexibly: BID at either 5 or 10 mg. Asenapine doses were up- or down-titrated based on efficacy, safety, and tolerability.

SECONDARY outcome

Timeframe: Baseline and Day 21

Population: Per protocol, the overall analysis population includes all randomized participants receiving ≥1 dose of study treatment, with ≥1 post-dose Y-MRS assessment. For Baseline / Change from Baseline data, includes only participants of the overall analysis population with an observation at the time indicated for the respective endpoint.

The least squares mean change from baseline in Q-LES-Q score at day 21 was assessed. The Q-LES-Q is a participant-completed questionnaire to assess general satisfaction with activities such as physical health, mood, work, household tasks, social and family relationships, leisure activities, and overall satisfaction, composed of 16 items. For each of the 16 items, scores range from 0 (very poor) to 5 (very good), with scores for all items adding to a total score (range: 0-80); higher scores indicate better quality of life. Further, decreases in quality of life are reflected by a negative change from baseline.

For Baseline / Change from Baseline data, includes only participants of the overall analysis population with an observation at the time indicated for the respective endpoint.

Least squares mean change from baseline at day 21 in quality of life was assessed, as determined by SF-36v2. The SF-36v2 is a self-administered questionnaire, measuring 8 domains: Physical Functioning (PF); Role-Physical (RP); Bodily Pain (BP); General Health (GH); Vitality (VT); Social Functioning (SF); Role-Emotional (RE); and Mental Health (MH). These 8 concepts are further organized into a Physical Component Summary (PCS; composite of PF, RP, BP, and GH) and a Mental Component Summary (MCS; composite of VT, SF, RE, and MH). The SF-36v2 domains and composite summaries were scored using a norm-based scoring approach, yielding a mean of 50 and standard deviation of 10 based on the norms from the 1998 SF-36 United States general population norms. For the PCS and MCS, scores range from 0 to 100, with higher scores indicating better quality of life. Further, decreases in quality of life (by PCS and MCS) are reflected by a negative change from baseline.
