Further study details as provided by Light Sciences Oncology:

Primary Outcome Measures:

Safety of Litx™ BPH System by Recording of Adverse Events; Preliminary effectiveness of Litx™ BPH System by evaluating the International Prostate Symptom Score (IPSS) along with Bother Score (BS). [ Time Frame: 9 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

To assess the effect of the Litx™ treatment following tests by: Maximum urinary flow rate (Qmax); Post void residual volume (PVR); Transrectal ultrasound (TRUS) to measure prostate size and treatment effect. [ Time Frame: 9 months ] [ Designated as safety issue: No ]

Estimated Enrollment:	12
Study Start Date:	June 2008

Arms	Assigned Interventions
Litx™ BPH Therapy: Experimental	Drug: Talaporfin sodium LS11 (Talaporfin Sodium) dose is 1mg/kg administered intravenously slow push (3-5 minutes). Procedure: Placement of device in prostate urethra Placement of device in prostate urethra Device: Transurethral illumination with light emitting diodes (Litx™ BPH Device) Patients in Cohort A will receive 50 J of light treatment with 1 mg/kg LS11 administration and patients in Cohort B will receive 70 J of light treatment with 1 mg/kg LS11 administration.

Arms

Assigned Interventions

Litx™ BPH Therapy: Experimental

Drug: Talaporfin sodium

LS11 (Talaporfin Sodium) dose is 1mg/kg administered intravenously slow push (3-5 minutes).

Procedure: Placement of device in prostate urethra

Placement of device in prostate urethra

Device: Transurethral illumination with light emitting diodes (Litx™ BPH Device)

Patients in Cohort A will receive 50 J of light treatment with 1 mg/kg LS11 administration and patients in Cohort B will receive 70 J of light treatment with 1 mg/kg LS11 administration.

Detailed Description:

The eligible patients will be enrolled into one of the two Litx™ treatment Cohorts (A or B)

All patients will undergo the procedure of Litx™ BPH Device placement into the prostate urethra.

Following the placement of the Litx™ BPH Device into the urethra, patients in Cohort A will be administered an intravenous dose of LS11 (talaporfin sodium) at 1 mg/kg by slow push over 3 - 5 minutes. Fifteen minutes after injection, each patient will be administered a 50 J total light dose, delivered at 20 mW/cm over a 42 minute time period.

Following the placement of the Litx™ BPH Device into the urethra, patients in Cohort B will receive LS11 intravenously at 1 mg/kg by slow push over 3 to 5 minutes. The light activation procedure is the same as that for Cohort A except that a light dose of 70 J will be delivered to each patient over a 58 minute time period.

After 30 days, patients who have not experienced an improvement in symptoms, as determined by the investigator, may undergo an additional interventional therapy with continued follow-up per the protocol.

At the end of 4 weeks following treatment of the last patient in Cohort A, the number of patients requiring surgical intervention for relief of primary symptoms will be assessed for futility of the current protocol prior to commencing with treatment of the first patient in Cohort B.

Eligibility

Ages Eligible for Study:	18 Years and older
Genders Eligible for Study:	Male
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

Males, 50 years or older, who are on an alpha blocker and/or a 5-alpha reductase inhibitor or a combination, and are candidates for interventional therapy. Patients to continue on an alpha blocker and/or 5-alpha reductase inhibitor for at least one-month after the Litx™ treatment, then tapered off medication at physician's discretion.
Patients who understand and have the ability to sign written informed consent prior to any study procedures and discontinuation of exclusionary medications.
Patients with moderate to severe BPH bother score >3 requiring non-medication intervention.2,3
Patients with an IPSS1 Score of >15 points.
