What believers are saying

  • PRESERVE I first-four-patient data presented February 2026 demonstrates safety feasibility.
  • HOPE Program expands access beyond trial to ineligible acute leukemia patients.
  • OPO partnerships with LifeGift since 2017 establish reliable donor supply chain.

What critics are saying

  • Only ~34,000 US organ donors annually limits addressable market to 9,000 patients.
  • PRESERVE I enrolled only 12 patients across five centers; slow enrollment threatens regulatory pathway.
  • Delayed GVHD or graft failure in later cohorts triggers FDA clinical hold.

What makes Ossium Health unique

  • Only off-the-shelf bone marrow bank sourced from deceased organ donors.
  • Eliminates living donor search delays; cryopreserved inventory available on-demand.
  • FDA-registered Indianapolis facility with 34,000 SF cleanrooms and CLIA certification.

Ossium Health's Indianapolis facility reflects the rise of life sciences real estate.

Ossium Health's Indianapolis facility reflects the rise of life sciences real estate. April 20, 2026 Indianapolis is home to Ossium Health, a biotech company which operates the world's first bone marrow bank for the treatment of diseases of the blood and immune systems. Bone marrow banking is the process of collecting, processing, and storing bone marrow stem cells so they are available for medical treatment when needed, rather than relying on live donors at the time of illness. Govenor Mike Braun toured Ossium's nearly 34,000 SF production facility at 5742 W 74th Street last week after recently announcing $1B in incentives for life sciences. The visit highlighted Ossium's innovative work and emphasized Indianapolis' potential for becoming the Silicon Valley for life sciences. The building includes multiple cleanrooms, research and development laboratories, bulk storage areas, and office space for a growing team of scientists, production specialists, and quality personnel. This type of buildout underscores a key trend in industrial real estate, which is that life sciences users require highly customized spaces that support strict regulatory standards, advanced infrastructure, and long-term scalability. Facilities like Ossium's push far beyond traditional warehouse or flex space, blending elements of industrial, lab, and office environments into a single, specialized footprint. Indianapolis continues to strengthen its position as a growing hub for life sciences and advanced manufacturing, and Weston Inc. is pleased to have Ossium as a tenant. Ask Weston Inc. any questions. Its representatives are available to help answer your questions.
