NCT03400150

Brief Summary

The BioProtect Balloon Implant™ System is intended to temporarily position the anterior rectal wall away from the prostate during radiotherapy for prostate cancer and in creating this space it is the intent of the balloon to reduce the radiation dose delivered to the anterior rectum. The balloon composed of a biodegradable material that maintains that space for the entire course of prostate radiotherapy treatment and is completely absorbed by the patient's body over time.

Outcome Measures

Primary Outcomes (2)

  • Safety Endpoint: Number of Subjects in the Balloon and Control Groups With Rectal, Device or Procedure-related Grade > 1 AEs Within 6 Months of Procedure

    Non-inferiority in occurrence of rectal, device or procedure-related Grade \> 1 AEs within 6 months of implantation for balloon as compared to control group

    Within 6 months from balloon implantation

  • Efficacy Endpoint: Number of Subjects in the Balloon Group With Reduction of >25% in Rectal Volume Receiving 70 Gy (rV70)

    Observed reduction of at least \>25% in rectal volume receiving 70 Gy (rV70) in patients after spacer implantation, with efficacy of the study confirmed if \>75% of balloon recipients achieved this degree of dose reduction.
