Recent progress at the National Center for Nanoscience and Technology of China has enabled an extremely facile method to encapsulate irinotecan (CPT-11) into micelle-based nanoparticles (named as IH-NM). In preclinical study, compared with free CPT-11, IH-NM exhibited 1.56-fold higher maximum tolerance dose (MTD), ∼2.45-fold higher antitumor efficacy at 80% of MTD dosage, higher plasma exposure, and slower clearance from the plasma. The IH-NM technology received Clinical Trial Permission from the National Medical Products Administration (NMPA) of China on Mar 6, 2019. The Phase I clinical trial is under preparation.
