Regulatory News:

THERACLION (Paris:ALTHE) (Euronext Growth, FR0010120402 – ALTHE), a company specialized in leading-edge medical equipment for echotherapy, and lead investigator Alfred Obermayer, M.D., vascular surgeon at the St. Joseph Hospital in Vienna, director of the Karl Landsteiner Institute for Functional Phlebology – Melk, Austria presented the preliminary results of the first clinical trial on Theraclion’s Echotherapy (also known as High Intensity Focused Ultrasound, HIFU) in the treatment of insufficient superficial and perforating veins of the lower limb. Dr. Obermayer presented that:

• The trial will enroll 35 patients and will be followed-up for 3 months after the procedure. The aim of the trial is to assess feasibility, blood reflux abolition, ease of use, patient preference, tolerability and safety of echotherapy.
• For all the patients treated in the study, the procedure was feasible, and no procedures were interrupted or cancelled due to technical or medical reasons related to the treatment.
• Most of the cases were severe Chronic Vein Disease patients with long history of treatments (surgery and thermal endovenous included), presenting active or healed ulcers, severe skin disorders, significant vein disease related symptoms, mostly over 50 yo and with a high BMI.
• Contrary to other thermal methods, which are endovenous, no analgesia was provided to the patients neither before, during nor after the treatments.
• No significant side effects were reported during the treatment and the follow-up period (no skin burns, skin changes, ecchymosis, erythema or edema were present during and after the procedure).
• All the patients were satisfied with the procedure.

Several examples of successful treatments were presented including incompetent anterior accessory saphenous veins, stumps (recurrences at the groin) and perforator veins, showing no blood reflux after echotherapy treatment.

"The preliminary results are very promising with a lack of significant adverse events” said David Caumartin, Chief Executive Officer of Theraclion. "Our hope is to offer a non-invasive new option for the growing number of patients suffering from chronic veins disease (CVD). Many of these patients, especially in recurrent disease or presence of active ulcer, do not respond well to existing surgical or endovenous treatments.”
