Kuros Biosciences to present positive clinical data for MagnetOs at NASS 2022 Annual Meeting

Schlieren (Zurich), Switzerland, 11 October, 2022 – Kuros Biosciences (“Kuros” or the “Company”), a leader in next generation bone graft technologies, announced today that it will present compelling clinical data on MagnetOs bone graft at the 38th Annual Meeting of the North American Spine Society (NASS), being held in Chicago October 12 to 15, 2022, in addition to completing a full commercial launch of MagnetOs Flex Matrix.

This first data, from the Company’s five planned randomized controlled trials for MagnetOs, compares MagnetOs Granules to the gold standard of autograft bone. The rate of posterolateral lumbar fusion of the first consecutive 50 patients in this preliminary analysis were assessed by CT-scan at Month 12 post-operation. The fusion rate for MagnetOs was 78% in comparison to 42% for autograft, comparing favorably to fusion rates of 55-71% reported for synthetic bone grafts evaluated in similar well-controlled studies.1

The full commercial availability of MagnetOs Flex Matrix opens an opportunity for surgeons who routinely mix their bone graft of choice with bone marrow aspirate, to reap the benefits of MagnetOs’ NeedleGrip surface technology while continuing with their routine peri-operative practice. The MagnetOs Flex Matrix product is extremely convenient to use, with excellent granule retention, remaining strong yet flexible even when wet, allowing wide-ranging manipulation to fill bony spaces in whichever way surgeons require.

Joost de Bruijn, Chief Executive Officer of Kuros, said: “These exciting data mark a significant milestone in the clinical phase of Project Fusion, which brings together an unprecedented blend of scientific, pre-clinical and clinical studies. The interim data exceed expectations for performance and validate MagnetOs as an augmented bone grafting option.

“Furthermore, the launch of MagnetOs Flex Matrix rounds out the family of MagnetOs products, meaning we have solutions that meet user needs in most peri-operative surgical scenarios in posterolateral fusion.”
