A pro-apoptotic solid dispersion comprises, in essentially non-crystalline form, a Bcl-2 family protein inhibitory compound of Formula I as defined herein, dispersed in a solid matrix that comprises (a) a pharmaceutically acceptable water-soluble polymeric carrier and (b) a pharmaceutically acceptable surfactant. A process for preparing such a solid dispersion comprises subjecting to elevated temperature the compound of Formula I, the water-soluble polymeric carrier and the surfactant, to provide an extrudable semi-solid mixture; extruding the semi-solid mixture; and cooling the resulting extrudate to to provide a solid matrix comprising the polymeric carrier and the surfactant and having the compound dispersed in essentially non-crystalline form therein. The solid dispersion is suitable for oral administration to a subject in need thereof for treatment of a disease characterized by overexpression of one or more anti-apoptotic Bcl-2 family proteins, for example cancer or an immune or autoimmune disease.
一种促凋亡的固体分散体,其中本质上非结晶形式地分散着一种Bcl-2家族蛋白抑制化合物,该化合物的
化学式如本文所定义,该固体分散体分散在包含(a)药用可接受的
水溶性聚合物载体和(b)药用可接受的表面活性剂的固体基质中。制备这种固体分散体的过程包括将化合物I的
水溶性聚合物载体和表面活性剂加热至高温,以提供可挤出的半固体混合物;挤出半固体混合物;并冷却所得的挤出物,以提供包含聚合物载体和表面活性剂的固体基质,并在其中分散化合物的本质上非结晶形式。该固体分散体适用于口服给予需要治疗由一个或多个抗凋亡Bcl-2家族蛋白过度表达所特征的疾病的患者,例如癌症或免疫或自身免疫疾病。
