About MM-398MM-398 is a novel nanoliposomal encapsulation of irinotecan sucrosofate. MM-398 is designed to optimize the delivery of irinotecan by extending the duration of circulation in the body and preferentially activating the drug within the tumor to achieve higher levels of the active cytotoxic, SN-38. MM-398 has been or is being evaluated in several clinical trials including a Phase 2 single agent study of MM-398 in metastatic pancreatic cancer, now in Phase 3, an ongoing Phase 2 study of MM-398 in combination with 5-FU and LV in patients with metastatic colorectal cancer, and a Phase 1 cross indication translational study. MM-398 is not approved for any indication by the FDA or any other regulatory agency. The salt form of the active ingredient within MM-398 liposomes was recently assigned the non-proprietary name - irinotecan sucrosofate, by the USAN (United States Adopted Name) council.
