Exclusion Criteria:
- Patients with known hypersensitivity to any of the components of the PEGylated AuroShell suspension (polyethylene glycol, gold)
- Patients who are receiving concurrent investigational therapy or who have received investigational therapy within a period of 5 half-lives of the investigational therapy in question prior to the day of dosing with the PEGylated AuroShell particles (investigational therapy is defined as treatment for which there is currently no regulatory authority approved indication)

- The presence of 3 or more MR Visible lesions positive on biopsy.

- Patients with acute or chronic hepatic dysfunction as evidenced by clinically significant abnormalities in albumin, total protein, or prothrombin time, or evidence of hepatic injury with clinically important (> grade 1) changes in AST, ALT, ALP, bilirubin, or GGT values.
- Patients with uncontrolled coagulopathies who are at increased risk of bleeding.

5. Study Description
Brief Summary
To determine the efficacy of using MRI/US fusion imaging technology to direct focal ablation of prostate tissue using nanoparticle-directed laser irradiation.
Detailed Description
This is an open-label, multi-center, single-dose study of AuroLase Therapy in the focal ablation of neoplastic prostate tissue via nanoparticle directed irradiation. The patient population consists of men with low to intermediate risk localized prostate cancer with MRI visible and confirmed focal areas of prostate cancer using MR US Fusion Guided Biopsy. The patient also has no disease detected via ultrasound guided biopsy outside of areas visualized on MR imaging.There is one arm/group to this study: Up to forty five (45) patients will receive a single intravenous infusion of AuroShell particles 12 to 36 hours prior to MRI/US guided laser irradiation using an FDA cleared laser and an interstitial optical fiber.
Efficacy and acute volume of ablation will be assessed by contrast-enhanced MRI 48 - 96 hours after laser illumination to allow time for the appearance of coagulative necrosis and prior to reconfiguration of tissue by lytic action. An appearance of a 'void' on MRI would be more generally expected than lesion shrinkage. Efficacy of focal ablation of prostate tissue will be assessed by MRI /Ultrasound guided biopsy at 3 months (primary endpoint) and again at 1 year after laser treatment. Per standard of care patient follow up will continue on a 6 month basis beyond the one year follow up but will be outside the scope of the study.
