Photodynamic Therapy for Localized Prostate Cancer

This study is testing a treatment called Photodynamic Therapy (PDT) for men with primary localized prostate cancer. PDT uses the SpectraCure P18 system along with a drug called Verteporfin for Injection (VFI). During the treatment, you would receive VFI intravenously (into a vein), and then optical fibers would be inserted into your prostate under general anesthesia to deliver light. The goal is to see how safe this treatment is, find the best light dose, and determine how well it works. The study is looking for men aged 18 or older with prostate cancer that has not spread, diagnosed within the last 9 months. The study will follow participants for 18 months to check the main results, with a total follow-up of 36 months.

Study design
This interventional study plans to enroll 43 participants. It has two parts: an initial phase to find the safest and most effective light dose, followed by a phase to confirm its effectiveness and safety.
What's involved
You would undergo Photodynamic Therapy (PDT) under general anesthesia, which involves an intravenous injection of Verteporfin and insertion of optical fibers into the prostate. You will be followed for 18 months, with a long-term follow-up extending to 36 months.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for 18 months to determine the primary outcomes, with an additional 18 months for long-term follow-up, totaling 36 months.

  • Safety of treatmentWithin 4 weeks of treatment in each cohort.

    Number of participants with treatment related adverse events as assessed by CTCAE v5.0 related to therapy per protocol. Dose limiting toxicities are defined as grade 3 non-hematologic or grade 4 hematologic toxicities that are possibly, probably or definitely related to PDT.

  • Safety - Damage to the periprostatic tissue mediated by PDT5-9 days following PDT

    Potential damage to the periprostatic tissue will be evaluated by contrast-enhanced and not-contrast enhanced MRI.

  • Treatment efficacy6 and 18 months post PDT
