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

What's the purpose of this trial?

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.

This trial is currently open and accepting patients.
