Pilot Study to Assess the Safety and Efficacy of BioProtect Balloon in Prostate Cancer Subjects

Completed · Not applicable

Conditions studied: Prostate Cancer

In brief

Primary Goal The study's primary goal is to assess the safety of the BioProtect biodegradable balloon implant and implantation procedure, in prostate cancer subjects undergoing routine radiation therapy (XRT) treatment. Safety of the BioProtect device will be assessed by reporting adverse events. Secondary Goal The study's secondary goal is to evaluate the effectiveness of the BioProtect biodegradable balloon implant in prostate cancer subjects undergoing routine XRT treatment. Effectiveness will be assessed in terms of increased distance between anterior rectal wall and prostate and noticeable reduction of isodose to the rectum.

• Subject is scheduled for only localized prostate XRT treatments
• Zubrod performance status 0-1; or Karnofsy >80
• Blood CBC and biochemistry up to two weeks before screening demonstrating:
• Platelets ≥ 100,000 cells/mm3

• Prior radical prostatectomy
• Prior cryosurgery or radiotherapy for prostate cancer, or other local therapy for prostate cancer
• Suspected extension of the prostate tumour toward the rectum as evidenced by acceptable imaging modalities used in the study site
• Prior surgical procedure involving peri-rectal and peri-prostatic area
• Prior radiotherapy to the pelvis, including brachytherapy at the same body organ
• Unstable angina
• Congestive heart failure (CHF) phase III or IV or CHF requiring hospitalization within the last 6 months prior to screening
• Transmural myocardial (MI) infarction within the last 6 months prior to screening
• Moderate to severe respiratory failure, hepatic failure or renal failure
• Acute infection requiring intravenous antibiotics at the time of screening
• Uncontrolled bleeding disorders

• Active inflammatory bowel disease or moderate to severe gastrointestinal (GI) disorders
• Known or suspected rectal carcinoma
• Subjects after anterior resection of rectum or after rectal amputation
• Concurrent participation in any other clinical study
• Intra-operative exclusion criteria:
• Irregular findings by the implanting physician before or during implantation that to the best of the implanting physician may lead to prostate compliance leading to urinary retention or other such symptoms.
