Photodynamic Therapy With Talaporfin Sodium (LS11) in Treating Patients With Refractory Colorectal Liver Metastases

The purpose of this study is to determine whether the Litx platform is safe and effective in the treatment of liver metastasis arising from colorectal cancer. Litx is a next-generation photodynamic therapy platform in which the drug, talaporfin sodium (LS11), is activated by light from the light-emitting diode (LED)-based light infusion device, inserted directly into the tumor through the skin prior to treatment.
