Open-label Clinical Phase 1/2 Study to Assess the Safety and Efficacy of the SpectraCure P18 System and Verteporfin for Injection for the Treatment of Primary Localized Prostate Cancer
SpectraCure AB
Summary
The goal of this study is to obtain safety data, establish dose parameters, and effectiveness of treatment for the SpectraCure P18 System with IDOSE®, together with verteporfin for injection (VFI) as photosensitizer, for the treatment of primary localized prostate cancer. The study will be divided into two parts, with Phase I, dose-escalation, to study safety and establish an effective light dose, followed by Phase II, cohort expansion, to evaluate clinical efficacy and confirm safety/tolerability. The subjects will be followed for a period of 18 months to determine the primary outcome. The long-term follow-up is an additional 18 months, i.e. a total of 36 months. Interstitial Photodynamic Therapy (PDT) will be performed during general anesthesia. Optical fibers will be inserted into the prostate with a transperineal approach using transrectal ultrasound guidance. The intent is to deliver an adequate light dose throughout the prostate. Subjects will receive VFI intravenously, approximately 60-90 minutes prior to light delivery.
Eligibility
- Age range
- 18+ years
- Sex
- Male
- Healthy volunteers
- No
Inclusion Criteria: 1. Subjects ≥ 18 years. 2. Histologically confirmed organ-confined adenocarcinoma of the prostate cancer diagnosed within the last 9 months. Including subjects on active surveillance with evidence of disease progression and a prostate biopsy not older than 9 months. a. This prostate biopsy should be targeted and systematic (transperineal or transrectal are both acceptable) and include both systematic sampling with a minimum of 8 cores (4 right, 4 left) as well as MRI fusion targeted cores. The minimum number of targeted cores is two (2) but more may be included at the…
Interventions
- DevicePhotodynamic Therapy (PDT)
The PDT treatment is provided with the SpectraCure P18 laser light delivery system. PDT will be performed during general anesthesia. Optical fibers will be inserted into the prostate with a transperineal approach using transrectal ultrasound guidance. The intent is to deliver an adequate light dose throughout the prostate. Subjects will receive VFI intravenously, approximately 60-90 minutes prior to light delivery. The photosensitizer is activated with light of a specific wavelength that is delivered to the tumor via optical fibers. The activated photosensitizer reacts with oxygen to form highly toxic radicals which induce cell death in the tumour. * Phase 1: Light dose escalation. Three subjects will be treated per dose level (20 - 40 J/cm2). If no dose-limiting toxicities occur, dose will be escalated (20 - 40 J/cm2) until the Recommended Phase 2 Dose (RPD2) is established. * Phase 2: Cohort expansion with the RPD2.
- DrugVerteporfin Injection
Verteporfin for Injection (VFI), photosensitizing drug, will be administered intravenously at a dose of 15 mg/m2 body surface area.
