2/6/2017 Houston, TX; Los Angeles, CA, Feb. 06, 2017 (GLOBE NEWSWIRE) -- RadioMedix, Excel Diagnostics and Nuclear Oncology Center (EDNOC), and the Ahmanson Translational Imaging Division at the David Geffen School of Medicine at UCLA announced that the U.S. Food and Drug Administration (FDA) has given clearance to their Investigational New Drug (IND) application for their Phase II clinical trial for the use of 177Lu-PSMA-617 for targeted Radioligand Therapy (RLT) in patients with castration-resistant prostate cancer.
This will be the first prospective clinical trial in the US with prostate specific membrane antigen (PSMA) directed radioligand therapy providing new treatment options for patients with advanced, castration resistant prostate cancer.
"We are very excited to have received IND clearance from the FDA so that we can move forward with this clinical trial which makes PSMA-directed radioligand therapy available for the first time in the United States," said Dr. Ebrahim Delpassand, RadioMedix founder and CEO and Co-Principle Investigator at EDNOC. He continued: ”This work would not have been possible without the close collaboration of our colleagues at UCLA and EDNOC in the United States and ABX and ITG in Germany. ABX’s proprietary ligand PSMA-617 and ITG Isotope Technologies Garching’s EndolucinBeta® (no-carrier added 177Lu) used in this Radioligand Therapy are unique features of this highly avid and environmentally friendly RLT compound”.
Dr. Johannes Czernin, Chief of the Ahmanson Translational Imaging Division at UCLA and Co-Principle Investigator of this trial adds "This is a great milestone in the field of Nuclear Medicine in the United States and addresses an unmet need in treatment of patients suffering from hormone refractory prostate cancer".
According to the American Cancer Society, prostate cancer is the most common cancer and second most frequent cause of cancer-related death in men in the United States. Metastatic castration-resistant prostate cancer, defined as disease progression despite medical or surgical castration, develops in 10%–20% of prostate cancer patients. The corresponding 5-y survival rate is much lower (31%) than for patients with locally advanced prostate cancer (nearly 100%). Most patients with metastatic castration-resistant disease have metastases at diagnosis or develop widespread disease during the first 2 years of follow-up. First-line chemotherapeutic agents such as docetaxel, and second-line chemotherapy with cabazitaxel, are often toxic and prolong life by only a few months, underlining the need for new therapeutic strategies. Retrospective studies suggest that PSMA-targeted radioligand therapy with 177Lu-PSMA 617 has a favorable safety profile and a high efficacy. This multi-center trial at Excel Diagnostics and at the UCLA Ahmanson Translational Imaging Division will generate important prospective data regarding safety and efficacy. The trial is expected to start first half of 2017.
