• Treatment with robotic HIFU showed reduction in moderate and severe post-operative complications and reduced hospital stay compared to surgery

LYON, France, November 19, 2024 - EDAP TMS SA (Nasdaq: EDAP), the global leader in robotic energy-based therapies, today announced a moderated scientific presentation of clinical data comparing Focal One HIFU versus surgery for the treatment of deep infiltrating endometriosis at the 2024 AAGL Global Congress, which took place from November 16-19, 2024, in New Orleans, LA. The presentation was entitled, "Evaluation of rectal endometriosis treatment with high-intensity focused ultrasound versus surgery: a retrospective multicenter study", and was delivered by Professor Gil Dubernard, Head of Gynecology Department at Croix-Rousse University Hospital, Lyon, France, and Principal Investigator.

"The comparative results from these two cohorts demonstrate that, based on its much less invasive treatment approach, robotic HIFU therapy could offer meaningful advantages over surgical intervention both with respect to reducing post-procedure complications, duration of hospital stay and improving overall patient health," said Professor Dubernard. "I look forward to seeing robotic HIFU technology continue to advance for the treatment of rectal endometriosis, which at present, has very few treatment alternatives other than highly invasive surgical procedures."

The objective of the study was to compare the management of rectal endometriosis with HIFU and surgery in terms of treatment-related improvements in symptoms and morbidity. The trial was designed as a comparative, retrospective, multicenter study that reviewed treatment outcomes of 120 patients issued from 2 prospective databases. The first cohort comprised 60 consecutive patients from the ENDO-HIFU-R1 Phase 2 study who underwent a High-Intensity Focal Ultrasound (HIFU) treatment of the posterior deep infiltrating endometriosis at 4 different centers. The second cohort was comprised of 60 patients from a large surgical database who had complete surgical excision of their endometriosis lesions, including digestive involvement.

Highlighted Results

• Compared to surgery, patients treated with HIFU therapy for the management of deep infiltrating rectal endometriosis nodules showed encouraging data with respect to health improvement, reduced rate of complications, shorter operating time, and reduction in length of hospital stay.
• Moderate and severe postoperative complications were significantly less frequent after HIFU treatment compared to surgery.
• These findings suggest that HIFU treatment could be an alternative to surgery in select patients with rectal endometriosis.
  

As previously reported, the Company's ongoing Phase 3 trial evaluating Focal One HIFU for the treatment of deep infiltrating endometriosis continues per protocol, with more than 85% of the patients initially in the Sham treatment arm having elected to receive HIFU therapy as their symptoms returned back to their high baseline levels. This additional data continues to suggest that HIFU therapy is a safe, non-invasive treatment that has significant potential to reduce pain for women suffering from this debilitating condition. Between now and year-end, the Company expects to communicate with the FDA to discuss this data and the next steps forward for this program.
