Preferred Name: Carboxylesterase-expressing Allogeneic Neural Stem Cells

Definition: A preparation of allogeneic neural stem cells (NSC), derived from a human fetal cell line, that are adenovirally-transduced to express a modified form of the human enzyme carboxylesterase (CE) hCE1m6, with potential adjuvant activity. Upon intracranial administration, NSCs localize to tumor sites, due to their tumor-trophic nature, and transiently express hCE1m6. Intravenous co-administration of the prodrug irinotecan allows for the selective conversion by hCE1m6 to its active metabolite and topoisomerase I inhibitor, SN-38, in the vicinity of tumor sites. This leads to a local anti-neoplastic effect and causes reduced toxicity and increased therapeutic efficacy of irinotecan. Since NSCs freely cross the blood-brain barrier, these cells can also be intravenously administered to target brain tumor cells. hCE1m6 shows increased activity as compared to unmodified human CE.
