Safety, Tolerability and Pharmacokinetics Investigation of Stimotimagene Copolymerplasmid
An Open Multicenter Study of the Safety, Tolerability, and Pharmacokinetics of Different Doses of Stimotimagene Copolymerplasmid at Patients With Advanced-stage Solid Tumors With Cymeven® (Ganciclovir) Infusions

Detailed Description
Stimotimagene copolymerplasmid is an anti-tumor gene therapy drug, contains super-coiled plasmid DNA encapsulated in polycationic envelope (PPT: polyethyleneimine (PEI) - polyethylene glycol (PEG) - TAT peptide). The plasmid encodes two therapeutic genes: herpes simplex virus thymidine kinase (HSVtk) and human granulocyte-macrophage colony-stimulating factor (hGM-CSF). HSVtk converts the prodrug ganciclovir to a toxin in cells that have been transfected by Stimotimagene copolymerplasmid, GM-CSF stimulates proliferation and differentiation of antigen-presenting cells.
Stimotimagene copolymerplasmid therapy is two-staged: (1) intratumoral injection of Stimotimagene copolymerplasmid, (2) intravenous administration of ganciclovir (Cimeven®) This is the first-in-human study of Stimotimagene copolymerplasmid which will be conducted in three arms. In this study dose escalation (Arm1) and number of drug administrations (Arms 2 and 3) will be explored. All study parts will investigate the safety, tolerability and pharmacokinetic profile of Stimotimagene copolymerplasmid.
