Mesoblast Secures FDA Nod for New Potency Assay to Monitor Ryoncil Production
Event summary
- Mesoblast received FDA approval for the T-cell Proliferation Inhibition BioAssay (TIBA) to monitor Ryoncil's potency.
- TIBA will be used alongside existing assays (IL-2Rα inhibition and CAP) for batch release and stability monitoring.
- Ryoncil is the first FDA-approved industrially-manufactured allogeneic MSC product for steroid-refractory acute graft versus host disease (SR-aGvHD).
- The approval ensures consistency and clinical effectiveness of Ryoncil during manufacturing process changes or new facility production.
The big picture
Mesoblast's FDA approval for the TIBA assay underscores the regulatory scrutiny and precision required for cellular therapies. This move aligns with broader industry trends toward enhanced quality control in biomanufacturing, particularly for complex allogeneic products. The approval could bolster Mesoblast's position in the inflammatory disease treatment market, especially as it seeks to expand Ryoncil's use beyond pediatric SR-aGvHD.
