Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine whether the Litx™ system is safe and effective in combination with chemotherapy 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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients that provide Informed Consent and satisfy the Eligibility Criteria will undergo CT or Ultrasound guided percutaneous placement of a single, two, three, or four Light Sources depending on their tumor characteristics. No more than 4 Light Sources will be used at a single treatment. The Light Sources may be used in a single lesion or in multiple lesions.

Following radiographic confirmation of Light Source placement, patients will receive an intravenous dose of LS11 at 40 mg/m². Fifteen minutes to 1 hour following completion of LS11 administration, delivery of 200 J/cm at 20 mW/cm light energy will begin. The Light Source will then be manually removed and the patients will be observed for acute complication of Light Source removal. Precautions for protection from external light exposure should be instituted beginning with the LS11 administration and be maintained as defined throughout the study period. On day 3 following Litx™ treatment the patient will receive a standard chemotherapy with Irinotecan or Oxaliplatin with or without 5FU and /or leucovorin for metastatic colorectal cancer. On day 30+5 and day 60+5 the patient will undergo clinical assessment and the tumor mass will be imaged using contrast enhanced spiral CT for determination of volume and radius of PDT necrosis.
