The present invention provides novel, serum-stable lipid particles comprising one or more active agents or therapeutic agents, methods of making the lipid particles, and methods of delivering and/or administering the lipid particles. More particularly, the present invention provides serum-stable nucleic acid-lipid particles (SNALP) comprising a nucleic acid (e.g., one or more interfering RNA molecules), methods of making the SNALP, and methods of delivering and/or administering the SNALP (e.g., for the treatment of cancer). In particular embodiments, the present invention provides tumor-directed lipid particles that preferentially target solid tumors. The tumor-directed formulations of the present invention are capable of preferentially delivering a payload such as a nucleic acid to cells of solid tumors compared to non-cancerous cells.
本发明提供了新型的血清稳定脂质粒子,包括一种或多种活性剂或治疗剂,制备脂质粒子的方法以及传递和/或管理脂质粒子的方法。更具体地,本发明提供了血清稳定的核酸脂质粒子(SNALP),包括核酸(例如一种或多种干扰RNA分子),制备SNALP的方法,以及传递和/或管理SNALP的方法(例如用于癌症治疗)。在特定实施例中,本发明提供了针对实体肿瘤的肿瘤定向脂质粒子。本发明的肿瘤定向配方能够优先将有效载荷如核酸传递到实体肿瘤细胞,而不是非癌细胞。
