作为一个热力学不稳定体系,非晶药物-高分子固体分散体(amorphous solid dispersion, ASD)的物理稳定性是这一制剂的主要风险之一。 我们提出了设计ASD的工作路线图,以降低ASD的稳定性风险。这一思路被业内同行广泛认可。 此外,我们提出“药物-材料-水”的分子间相互作用是决定ASD药学表现的核心影响因素,并且建立了表征“药物-材料-水”三者相互作用的方法学。我们还通过体内外实验明确证明了药物-材料的相互作用对药物制剂的溶出,生物利用度的影响。 以上这些工作对难溶药物的制剂设计和优化具备重要应用意义。

两个mAb(JM1,JM2)的高浓度溶液的粘度可以被一些氨基酸盐大幅降低,并且其物理稳定性维持不变(Molecular Pharmaceutics, 2015, 12 (12), pp 4478–4487)。
不同药物制剂对NSCLC PDX (非小细胞肺癌,病人癌症组织移植瘤模型)的治疗效果。给药方式:静脉注射,每周一次,共4次。停药之后观察2个月。一线化疗药物和联合用药(图A中的3和4)虽然在给药期间可以抑制肿瘤生长,但是停药之后肿瘤很快复发;而新型制剂最大程度地抑制了肿瘤的生长,并且防止肿瘤的复发(图B,停药两个月之后小鼠体内肿瘤大小)。
