BACKGROUND AND OBJECTIVES: Twenty-seven patients with refractory liver metastases from colorectal cancer took part in a Phase II study of the light infusion technology (Litx) light-activated drug/device system to assess safety and evaluate time to tumor progression (TTP).
METHODS: Litx consists of the light-activated drug, talaporfin sodium (LS11), activated intratumorally by a catheter-like array of light-emitting diodes (LEDs). After placement of the array via ultrasound or computed tomography (CT) guidance, LS11 was administered intravenously, followed 15-60 min later by light infusion for 2.8 hr. Patients were assessed for adverse events and tumor response using physical examination, laboratory values, and CT scan evaluation over a period of 60 days.
RESULTS: The observed occurrence of Litx treatment-related adverse events was minimal and cumulative toxicity did not occur when combined with chemotherapy. Assessment of TTP and tumor response rate, although statistically non-robust, suggest potential improvement.
CONCLUSIONS: The Litx system was shown to be safe for treating liver metastases from colorectal cancer and there was no cumulative toxicity when combined with standard systemic therapy. Preliminary assessments of TTP and tumor response rate justify further evaluation in a Phase III follow-up study.
