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 dissolving the compound, the polymeric carrier and the surfactant in a suitable solvent, and removing the solvent 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.
一种促凋亡的固体分散物,其主要以非晶态形式分散在固体基质中,该基质包括以下成分:(a)一种药用可接受的水溶性聚合物载体和(b)一种药用可接受的表面活性剂,其中所述化合物为以下公式I所定义的Bcl-2家族蛋白抑制剂。制备这种固体分散物的方法包括将化合物、聚合物载体和表面活性剂溶解在适宜的溶剂中,并去除溶剂以提供包含聚合物载体和表面活性剂并在其中以基本非晶态形式分散有化合物的固体基质。该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家族蛋白过度表达引起的疾病,例如癌症的患者。
