The Challenge to Deliver Oxaliplatin (l-OHP) to Solid Tumors: Development of Liposomal l-OHP Formulations.

ABSTRACT

Oxaliplatin (l-OHP) is a third-generation platinum (Pt) agent approved for the treatment of patients with advanced colorectal cancer. Despite the fact that l-OHP has shown clinical therapeutic efficacy and better tolerability compared with other Pt agents, the use of l-OHP has been limited to clinical settings because of dose-limiting side effects such as cumulative neurotoxicity and acute dysesthesias, which can be severe. In preclinical and clinical studies, our group and several others have attempted the delivery of l-OHP to solid tumors via encapsulation in PEGylated liposomes. Herein, we review these attempts.
