A Phase 1, Open-Label, Dose Escalation and Dose Expansion Study of CLN-978 (CD19XCD3XHSA) in Patients with Relapsed/Refractory (R/R) B-Cell Non-Hodgkin Lymphoma (B-NHL) (ASH 2023)
Approximately 90 patients (30 in dose escalation and 60 in dose expansion) will be enrolled at approximately 6 sites in the U.S., reflecting both community and academic centers. The study is currently enrolling (NCT05879744).

CLN-978, a novel half-life extended CD19/CD3/HSA-specific T cell-engaging antibody construct with potent activity against B-cell malignancies with low CD19 expression. (PubMed, J Immunother Cancer)
CLN-978 warrants further exploration. An ongoing clinical phase 1 trial is investigating safety, pharmacokinetics, pharmacodynamics, and the initial therapeutic potential of subcutaneously administered CLN-978 in patients with non-Hodgkin's lymphoma.

Preclinical characterization of a next-generation CD19/CD3-bispecific T cell engager with extended serum half-life and superior potency against CD19-low target cells (AACR 2022)
Both the CD19-specific T cell-engaging bispecific antibody blinatumomab and various autologous CAR-T cell therapies have exhibited robust clinical activity in relapsed/refractory acute lymphocytic leukemia (ALL) and non-Hodgkin lymphoma (NHL). The cross-reactivity of CLN-978 to the NHP orthologs of CD19, CD3 and albumin enables assessment of depletion of normal B cells, strategies to mitigate cytokine release, PK and PD properties, and exploration of dosing routes. CLN-978 holds promise as a CD19-targeted therapeutic that can be easily and conveniently administered to patients with diverse B cell malignancies.
