Hybridyne Health Collaborates with Aytu BioScience for Minimally Invasive Prostate Cancer Detection

Englewood, CO – March 2, 2016 – Aytu BioScience, Inc. (OTCQX: AYTU), a commercial-stage specialty healthcare company focused on commercializing treatments for urological conditions, today announced that it has entered into a study agreement with Hybridyne Imaging Technologies to investigate the efficacy of Hybridyne’s ProxiScan™ compact gamma cameras to detect local prostate cancer using Aytu’s imaging agent ProstaScint®. The study is being conducted at The Princess Margaret Cancer Centre in Toronto, Canada, and supported by Hybridyne. As part of the agreement Hybridyne will purchase ProstaScint for the study, establishing Aytu’s first ProstaScint sales outside the U.S.

ProstaScint is FDA-approved and the only imaging agent that specifically targets prostate cancer cells and demonstrates high sensitivity, specificity, and accuracy. Hybridyne’s high-resolution ProxiScan gamma camera utilizes cutting-edge cadmium zinc telluride (CZT) detector technology and is small enough for trans-rectal prostate cancer diagnosis, after the patient is injected with a radiopharmaceutical such as ProstaScint. Combined, these technologies stand to offer additional diagnostic and prognostic assurances to urologists, ultimately increasing the quality of care for prostate cancer patients in Canada.

Josh Disbrow, Chief Executive Officer of Aytu, stated, “Prostate cancer is the second leading cause of cancer death among men, marking a great need for better detection in both newly diagnosed, high-risk patients and patients with biochemical recurrence. We are excited to initiate this study with Hybridyne and Princess Margaret Cancer Centre as it is Aytu’s first clinical collaboration with ProstaScint outside the U.S. This collaboration demonstrates our strong interest in gaining clinical acceptance of ProstaScint around the world while developing additional clinical data supporting ProstaScint’s use. ProstaScint is the only FDA-approved agent that can specifically target prostate cancer, while ProxiScan has demonstrated highly detailed trans-rectal image quality in prostate cancer. Both products have strong potential roles to play in the identification and treatment of both new and recurrent prostate cancer patients, and we look forward to seeing the results of this clinical study following study completion.”

The planned study Detection and localization of carcinoma using high resolution transrectal gamma imaging (TRGI) is being led by Principal Investigator Dr. Antonio Finelli. The study is being conducted at Princess Margaret Cancer Centre, Canada’s largest cancer treatment center.

Approximately 60 men will take part in this three-arm, open label study, including the following patient groups:

  • Group 1: Patients who have rising levels of PSA (>0.05ng/ml) after radical prostatectomy treatment
  • Group 2: Patients who have rising PSA (>10ng/ml) and/or abnormal digital rectal exam and have previously undergone at least one prostate biopsy that was determined to be negative for prostate cancer
  • Group 3: Patients diagnosed with prostate cancer (with at least one positive prostate biopsy) and have a scheduled biopsy as part of their routine follow-up
