The presentations will feature 3-month and 6-month endpoints clinical data from the Phase IIa (NCT06233474) for Allocetra™ in patients with moderate-to-severe knee osteoarthritis (KOA).

The data will be presented by Prof. Philip Conaghan, Consultant Rheumatologist and Director of the NIHR Leeds Biomedical Research Centre. Professor Conaghan is an international leader in osteoarthritis and musculoskeletal imaging, who has authored more than 700 publications and chaired multiple global guidelines and trial initiatives. In addition, the Company will present comprehensive pharmacological characterization data supporting the novel immunomodulating mechanism of action of Allocetra^TM.
