    Teniposide (VM-26) is a semisynthetic derivative of podophyllotoxin effective for the treatment of many types of tumors. However, the poor water solubility and adverse effects restrict its clinical use. Our study aimed to develop a novel phospholipid complex albumin nanoparticle (VM-E80-AN) to reduce the systemic toxicity and enhance antitumor activity of VM-26. Egg yolk lecithin E80 and human serum albumin (HSA) were used as the main excipients to replace Cremophor EL in the commercial formulation. The physicochemical properties of VM-E80-AN were characterized to optimize the formulation. Cell and animal studies were further carried out to estimate its tumor inhibition efficacy, biodistribution, and toxicity. Comparison between VM-26 solution and VM-E80-AN showed that VM-E80-AN significantly reduced the toxicity of VM-26 and enhanced the anticancer efficacy of the drug. Thus, VM-E80-AN represents a safe and promising formulation of teniposide for clinical application. Copyright © 2015 Elsevier B.V. All rights reserved.
