Study Description

Brief Summary:

The purpose of the study is to assess the survival of patients treated with Litx™ versus standard of care therapies in the treatment of unresectable hepatocellular carcinoma (HCC), and to demonstrate the safety of Litx™ therapy.

Litx™ consists of a light-activated drug, talaporfin sodium (LS11, Light Sciences Oncology, Bellevue, Washington), and a light generating device, composed of light-emitting diodes (LEDs), that is energized by a power controller and percutaneously placed in the target tissue inside the body.

Condition or disease	Intervention/treatment	Phase
Carcinoma, Hepatocellular; Liver Neoplasms	Drug: Talaporfin sodium; Device: Interstitial Light Emitting Diodes; Procedure: Percutaneous placement of device in the liver; Procedure: Standard Care	Phase 3

Detailed Description:

Patients who provide Informed Consent and satisfy the Eligibility Criteria will be placed in an eligibility pool for randomization for either the Litx™ treatment arm or the standard of care arm.

A Patient assigned to the Litx™ treatment group may receive up to three Litx™ treatments. Regardless of which group the patient is assigned the treatment planning should anticipate ablation of all lesions with three Litx™ treatments using up to 4 Light Sources per treatment (a single Light Source may kill 2 cm x 4 cm of tissue).

The Litx™ treatment group 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 Source(s) may be used in a single lesion or in multiple lesions. Following imaging confirmation of Light Source placement, patients will receive an intravenous dose of LS11 at 1 mg/kg. Fifteen minutes to one hour following completion of LS11 administration, delivery of 200 J/cm per Light Source at 20 mW/cm light energy will begin. The Light Source will then be manually removed and the patients will be observed for any complication after Light Source removal. Precautions for protection from external light exposure should be instituted beginning with the LS11 administration and maintained for up to two weeks.

Patients designated for the standard of care group, will receive current standard of care treatment recommended by the investigating physician. Should the elected treatment fail, a patient may switch to another standard of care treatment.

A patient designated for the Litx™ treatment group may receive up to two additional Litx™ treatments. A second and third treatment with Litx™ may be considered if any residual tumor or new tumor exists. The third treatment must take place within six months after the first treatment. A patient may switch to receiving standard of care after the third Litx™ treatment or as recommended by the investigator as necessary.

For either the Litx™ group or standard of care group once all treatment therapies have been exhausted the patient will be followed for survival. No protocol-directed office visits are required during this period and the patient may be followed by phone and/or e-mail at four week intervals. All patients will be monitored for survival from the time of randomization to the time of death from any cause or until at least 142 deaths have been observed, whichever occurs first.
