Interim results from the ELiPSE-1 study: A phase 1, multicenter, open-label study of CNTY-101 in subjects with relapsed or refractory CD19-positive B-cell malignancies. (ASCO 2024) - P1 | "CNTY-101 administered as a single dose in multiple cycles has demonstrated a manageable safety profile and preliminary evidence of efficacy. Allo-Evasion edits may allow for repeat dosing for multiple cycles without allorejection in the absence of lymphodepletion. Preliminary efficacy supports dosing at higher dose levels and with more dose-intense regimens."

CNTY-101, an iPSC-Derived Allogeneic CD19 Targeting CAR-NK Product, Exhibits Robust B Cell Depletion and Has Broad Potential for Development in B Cell-Driven Autoimmune Diseases (EULAR 2025) - P1 | "To evaluate CNTY-101 functionality and ability to evade host immunity, samples from patients treated in the dose level 3B cohort (≥1 cycle of three weekly doses of 1 billion cells administered following cyclophosphamide and fludarabine pre-conditioning regimen) of the ELiPSE-1 study were evaluated. Our results provide evidence that CNTY-101, an allogenic cell therapy, both evades host rejection and depletes B cells effectively. Century’s proprietary Allo-Evasion™ technology enables a multi-dose regimen in the presence of restored endogenous NK and T cells which can confer prolonged pharmacological pressure on pathogenic B cells. Collectively, these findings support the clinical development of CNTY-101 in autoimmune diseases in the CALiPSO-1 study."

Early discontinuation of ELiPSE-1 program in late-stage R/R NHL (GlobeNewswire) - "While the company remains encouraged by the clinical activity and tolerability profile of CNTY-101 in late-stage relapsed-refractory non-Hodgkin’s lymphoma (R/R NHL), the emerging clinical data do not meet the company’s threshold to be considered transformational in this patient population and the program is being discontinued. The company is committed to providing continued treatment access in the ELiPSE-1 trial for patients showing benefit....in addition to encouraging clinical activity in a difficult to treat R/R NHL population and a favorable tolerability profile, translational data also showed evidence of CNTY-101 trafficking to lymph nodes and deep B cell depletion following treatment. The ELiPSE-1 data continues to support proof-of-concept for Allo-Evasion and the ability to enable repeat dosing of the company’s cell therapies. Further data is expected to be presented in 2025."
