A pro-apoptotic solid dispersion comprises, a Bcl -2 family protein inhibitory compound of Formula A 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 A, 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 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物包括本文所定义的Formula A的Bcl-2家族蛋白抑制化合物,分散在包括(a)药学上可接受的水溶性聚合物载体和(b)药学上可接受的表面活性剂的固体基质中。制备这种固体分散物的方法包括将Formula A的化合物、水溶性聚合物载体和表面活性剂置于高温下,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,并且其中的化合物以基本非晶形式分散其中。这种固体分散物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。
