SAINT-GENIS-POUILLY, France, Sept. 06, 2016 (GLOBE NEWSWIRE) -- Advanced Accelerator Applications S.A. (NASDAQ:AAAP) (“AAA” or the “Company”), an international specialist in Molecular Nuclear Medicine (MNM), today announced the initiation of two Phase II clinical studies evaluating 99MrhAnnexin V-128 (Annexin), a single-photon emission computed tomography (SPECT) diagnostic candidate for the assessment of apoptosis and necrosis, forms of cell death in cardiovascular and cardio-oncology indications at the University of Ottawa Heart Institute and The Ottawa Hospital.
Annexin V is a human protein that binds to phosphatidylserine (PS), which is expressed on the surface of physiologically stressed, depolarized, or apoptotic cells. Technetium-99m (99mTc) is a medical isotope widely used in diagnostic imaging. 99mTc-labeled annexin V has demonstrated the ability to image cellular stress, membrane depolarization, apoptosis and necrosis in a variety of inflammatory diseases including atherosclerosis, myocarditis, acute heart transplant rejection, rheumatoid arthritis, prosthetic joint infection and Crohn’s disease in both human and animal studies.
One proof of concept study will determine the feasibility of imaging apoptotic activity by using 99mTc-rhAnnexin V-128 in carotid atherosclerotic plaques of asymptomatic patients with significant carotid artery disease. The goal of this study is to demonstrate the potential utility of Annexin in staging plaque vulnerability, thereby enabling more precise stratification of patient risk, which may impact intervention decisions. Thirty-five evaluable, asymptomatic patients with diagnosed carotid atherosclerotic plaque will be enrolled in the trial, in addition to a control group of ten participants with normal carotid ultrasound imaging.
A second study will investigate 99mTc-rhAnnexin V-128 imaging of apoptosis in the evaluation of doxorubicin-induced cardiotoxicity in patients with early stage breast cancer. Thirty evaluable patients with early stage breast cancer will be enrolled in this trial.
Terrence D. Ruddy, MD, FRCPC, FACC, Director of Nuclear Cardiology at the University of Ottawa Heart Institute, and Professor of Medicine and Radiology at the University of Ottawa is the Principal Investigator for both studies. He commented, “We completed a Phase I study of rhAnnexin V-128 in twelve normal volunteers, which demonstrated that this radiotracer was well-tolerated, with low radiodosimetry. In preclinical studies, we have demonstrated that imaging of apoptosis with 99mTc rhAnnexin V-128 can identify advanced atherosclerotic plaques and anticipate similar imaging of apoptosis in patients with carotid artery disease will also identify more advanced disease and facilitate patient management. In the second phase II study, we anticipate that imaging of apoptosis will be a sensitive imaging technique for identifying patients with early cardiotoxicity due to anthracycline chemotherapy for breast cancer and represent a new safety monitoring approach for this therapy. In both patient populations, we believe that apoptosis imaging will assist risk stratification and guide medical therapy.”
Susan Dent, MD, FRCPC, Medical Oncologist at The Ottawa Hospital, Associate Professor of Medicine at the University of Ottawa, Director of the Ottawa Cardio-Oncology Program and a co-investigator on the cardiotoxicity study, stated, “Anthracyclines continue to play an important role in the treatment of breast cancer. Anthracycline based therapy is associated with an increased risk of cardiotoxicity, in particular heart failure. Current cardiovascular imaging strategies (e.g. echocardiography) detect cardiotoxicity only once structural damage has occurred. The development and testing of diagnostic tools (such as imaging of apoptosis) that detect cardiotoxicity early, would facilitate the identification of cancer patients at high risk, leading to early medical management and completion of cancer therapy.”
Stefano Buono, Chief Executive Officer of AAA said, “Having diagnostic tools that can accurately detect apoptosis and necrosis in cardiovascular settings can facilitate early diagnosis of potentially life-threatening conditions, enable more precise risk stratification, and help physicians monitor the efficacy and safety of treatments in individual patients during the course of therapy. Our goal is to develop Annexin into a personalized disease management tool for multiple inflammatory diseases.”
