When bipolar I disorder (BP-I) mania is accompanied by subsyndromal depressive symptoms, a more complicated illness presentation results. To qualify for the mixed features specifier during mania, the DSM-5 requires ≥3 "non-overlapping" depressive symptoms (DS); notwithstanding, concerns of this definition's ecological validity and implications for timely diagnosis remain.
Herein, patients were pooled from three similarly-designed pivotal trials of cariprazine compared to placebo for BP-I mania (NCT00488618/NCT01058096/NCT01058668) in post hoc analyses of mixed features using three criteria: ≥3 DS (DSM-5), ≥2 DS, and Montgomery-Åsberg Depression Rating Scale (MADRS) total score ≥10. Efficacy of cariprazine compared to placebo was assessed (Week 3) by Young Mania Rating Scale (YMRS) and MADRS scores and rates of mania response and remission.
In pooled patients (N = 1037), cariprazine significantly improved mean YMRS scores compared to placebo for each criterion; LSMDs were ≥3 DS = -3.79 (P = .0248), ≥2 DS = -2.91 (P = .0207), and ≥10 MADRS = -5.49 (P < .0001). More cariprazine- than placebo-treated patients met YMRS response and remission criteria, reaching significance for response in ≥2 DS (34% versus 47%; number-needed-to-treat [NNT] = 8, P = .0483) and ≥10 MADRS (31% versus 57%, NNT = 4, P < .0001) and for remission in ≥2 DS (27% versus 39%, NNT = 9, P = .0462), ≥10 MADRS (23% versus 44%, NNT = 5, P < .0001). Depressive symptoms were improved compared to placebo, reaching statistical significance in the MADRS ≥10 subgroup (LSMD = -1.59, P = .0082).
Post hoc analysis, MADRS < 18 entry criterion may have prevented assessment of MADRS changes.
Cariprazine significantly reduced manic and depressive symptoms in patients with mixed features with differential efficacy across the subgroups analyzed herein.
当双相情感障碍 I 型(BP-I)躁狂伴有亚综合征性抑郁症状时,会出现更复杂的疾病表现。为了在躁狂中符合混合特征的标准,DSM-5 要求至少有 3 个“不重叠”的抑郁症状(DS);尽管如此,人们仍然对该定义的生态有效性和对及时诊断的影响表示担忧。
在此,对卡利拉嗪治疗 BP-I 躁狂的三项类似设计的关键性试验(NCT00488618/NCT01058096/NCT01058668)中的患者进行了事后混合特征分析,使用三个标准来评估混合特征:≥3 个 DS(DSM-5)、≥2 个 DS 和蒙哥马利-阿斯伯格抑郁评定量表(MADRS)总分≥10。采用 Young 躁狂评定量表(YMRS)和 MADRS 评分评估卡利拉嗪与安慰剂相比的疗效(第 3 周),以及躁狂反应和缓解的比例。
在汇总患者(N=1037)中,与安慰剂相比,卡利拉嗪在每个标准上均显著改善了 YMRS 评分的平均值;LS 均值分别为≥3 个 DS= -3.79(P=0.0248),≥2 个 DS= -2.91(P=0.0207),MADRS 总分≥10= -5.49(P<0.0001)。与安慰剂相比,更多的卡利拉嗪治疗患者达到了 YMRS 反应和缓解标准,在≥2 个 DS(34%对 47%;需要治疗的人数[NNT]为 8,P=0.0483)和 MADRS 总分≥10(31%对 57%,NNT 为 4,P<0.0001)方面达到了统计学意义,在≥2 个 DS(27%对 39%,NNT 为 9,P=0.0462)和 MADRS 总分≥10(23%对 44%,NNT 为 5,P<0.0001)方面达到了缓解标准。与安慰剂相比,抑郁症状得到了改善,在 MADRS 总分≥10 亚组中达到了统计学意义(LS 均值= -1.59,P=0.0082)。
事后分析,MADRS<18 的纳入标准可能阻止了 MADRS 变化的评估。
卡利拉嗪显著减轻了伴有混合特征的患者的躁狂和抑郁症状,在分析的亚组中具有不同的疗效。
