A Phase 3 Randomized Study to Evaluate Survival of Patients Treated With Talaporfin Sodium (LS11) and Interstitial Light Emitting Diodes (LED) as Compared to the Standard of Care Therapies in the Treatment of Unresectable Hepatocellular Carcinoma (HCC)

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.

Inclusion Criteria:

- A diagnosis of primary Hepatocellular Carcinoma (HCC), established by any one of the
following criteria in a clinical setting suggestive of HCC: A. Two different imaging
techniques with characteristics that suggest HCC; B. Combination of one imaging
technique that suggests HCC and serum AFP level >400 ng/mL; C. Histological evidence
of HCC

- ECOG Performance Status 0-2

- Life expectancy of at least 16 weeks

- Patients may have received previous antineoplastic therapy; at least 3 weeks must
have elapsed since the completion of any prior therapy and the patient must have
recovered from acute side effects.

- Understanding and ability to sign written informed consent

- 18 years of age or more

- Adequate hematologic, liver and renal functions as evidenced by the following: WBC >=
2,400/mm³ ; Platelet Count >= 75,000/µl ; Hemoglobin >= 9.4 gm/dL ; PT and PTT <= 1.5
Control ; SGOT, SGPT <= 5 × ULN ; Bilirubin <= 2.5 × ULN ; Alk Phos <= 3 × ULN ;
Creatinine <= 2.5 mg/dL (SI: 221 mmol/L) ; Albumin >= 2 g/dL

Exclusion Criteria:

- Patients who are candidates for surgery with curative intent are not eligible

- Patients with 6 or more lesions are not eligible

- Patients with greater than 50% of parenchyma disease involvement are excluded

- Patients with Child-Pugh C cirrhosis are excluded

- Patients with diffuse HCC are excluded

- Patients with grade 3 ascites are excluded

- Evidence of major vessel invasion or extrahepatic disease is excluded. Lymph node
involvement in the hilum region of the liver is eligible if the nodes do not exceed 2

- Known sensitivity to porphyrin-type drugs or known history of porphyria are

- Pregnancy or breast-feeding patients are excluded. A negative pregnancy test (urine
or serum) from women of childbearing age is required prior to enrollment. A fertile
patient must use effective contraception during participation in the study

- Concurrent participation in another clinical trial involving experimental treatment
is excluded

- Any concurrent disease or condition that in the opinion of the investigator impairs
the patient's ability to complete the trial such as psychological, familial,
sociological, geographical or medical conditions which in the Principal
Investigator's opinion could compromise compliance with the objectives and procedures
of this protocol or obscure interpretation of the trial's data are excluded.
