Clinical Study to Assess the Safety and Efficacy of the SpectraCure P18 System

Open-label Clinical Study to Assess the Safety and Efficacy of the SpectraCure P18 System (Interstitial Multiple Diode Lasers and IDOSE® Software) and Verteporfin for Injection (VFI) for the Treatment of Recurrent Prostate Cancer


Sponsor

SpectraCure AB

Enrollment

66 participants

Start Date

Mar 21, 2017

Study Type

INTERVENTIONAL

Conditions

Summary

The rationale for the study is to obtain safety and efficacy data as well as to establish dose parameters for the SpectraCure P18 System with IDOSE®, with verteporfin for injection (VFI) as photosensitizer for the treatment of recurrent prostate cancer.

  • Gleason score ≥ 8 at initial diagnosis
  • Less than 1 week since surgery (excluding minimal procedures, e.g. vascular access device insertion)
  • Concomitant infection

  • Subjects with a history of CTCAE v4 grade 3 or greater or persistent (\>1 separate episode or symptoms lasting more than 3 months after initiation of medical intervention) grade 2 proctitis attributed to radiation.
  • Subjects with locally advanced (AJCC 7th edition T3/T4), regional pelvic lymph node metastasis, or metastatic disease defined by PSMA PET.
  • Subjects who have been treated with seed implantation brachytherapy.
  • Less than 1 week since surgery (excluding minimal procedures, e.g. vascular access device insertion).
  • Concomitant infection.
  • Subjects with other severe concurrent disease that in the judgement of the investigator would make the subject inappropriate for entry into this study.
  • Mental incapacity or psychiatric illness that would interfere with the subject's ability to understand and give informed consent or to complete follow-up visits according to the judgement of the investigator.

  • Enrolment in another therapeutic clinical study within 3 months prior to randomization and throughout the study.
  • Subjects with a history of CTCAE v4 grade 3 or greater or persistent (\>1 separate episode or symptoms lasting more than 3 months after initiation of medical intervention) grade 2 proctitis attributed to radiation.
  • Contraindication for MRI/Gadolinium contrast such as: implants, severe renal impairment (glomerular filtration rate \[GFR\] \<30 mL/min/1.73m2, or previous contrast reactions.
  • On-going or planned hormone therapy.

Interventions

DRUGVerteporfin

In the last decade a clinical interest of developing new methods for minimally invasive treatments of organ-confined prostatic malignancies has been pursued. In this study the drug verteporfin for injection (VFI) is to be used with the SpectraCure P18 System (Interstitial multiple diode lasers and IDOSE® Software).
