The company’s off-the-shelf CAR EBV T-cell platform continues to demonstrate versatility across multiple therapeutic areas, moving beyond traditional oncology applications into autoimmune disease treatment.

Tabelecleucel (tab-cel®/EBVALLO) Advancement in PTLD Treatment

The company is on track to submit a Biologics License Application in Q2 2024 for tabelecleucel in Post-Transplant Lymphoproliferative Disease.
