SAN FRANCISCO--(BUSINESS WIRE)--Jan 23, 2026--

Ossium Health, a clinical-stage biotechnology company pioneering off-the-shelf bone marrow therapies derived from deceased organ donors, today announced it will present new clinical data from its ongoing PRESERVE I study at the 2026 Tandem Meetings taking place on February 4-7, 2026 in Salt Lake City, UT.

Ossium will deliver one oral presentation and three poster presentations highlighting clinical experience with its cryopreserved, donor-derived bone marrow platform. The featured oral presentation will showcase first-in-human clinical data from the first four patients treated in the PRESERVE I study, marking an important milestone in the advancement of off-the-shelf bone marrow transplantation. Ossium’s Chief Medical Officer, Dr. Sagar Munjal, will present the study’s encouraging preliminary data, which demonstrate the safety and feasibility of transplanting bone marrow derived from deceased donors.
