CLBR001 + SWI019 is an combination investigational immunotherapy being evaluated as a potential treatment for patients diagnosed with B cell malignancies who are refractory or unresponsive to salvage therapy or who cannot be considered for or have progressed after autologous hematopoietic cell transplantation. This first-in-human study will assess the safety and tolerability of CLBR001 + SWI019 and is designed to determine the maximum tolerated dose (MTD) or optimal SWI019 dose (OSD). Patients will be administered a single infusion of CLBR001 cells followed by cycles of SWI019. The study will also assess the pharmacokinetics and pharmacodynamics of CLBR001 + SWI019.

Official Title

A Phase 1, Open-label, Dose Escalating Study Evaluating the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics and Clinical Activity of the Combination of CLBR001 and SWI019 in Patients With Relapsed/Refractory B-cell Malignancies


CLBR001 + SWI019 is a two-component therapy comprising an autologous chimeric antigen receptor T (CAR-T) cell product (CLBR001, the switchable CAR-T cell (sCAR-T)) and an anti-CD19 (cluster of differentiation antigen 19) antibody (SWI019, the switch, a biologic). In combination, SWI019 acts as an adapter molecule that controls the activity of the CLBR001 CAR-T cell product.
