Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Part 1: dose finding utilizing a "3+3" enrollment schema and safety lead-in to confirm dose for NKX019 in combination with rituximab expansion cohorts (as applicable) Part 2: dose expansion to further evaluate safety and tolerability, cellular kinetics, pharmacodynamics and anti-tumor response in expansion cohorts of patients with large B cell lymphoma (LBCL), mantle cell lymphoma (MCL), indolent lymphoma (IL), Waldenström macroglobulinemia (WM), CLL/ small lymphocytic lymphoma (SLL), and B-ALL.

NKX019 - CAR NK cell therapy
All subjects will receive fludarabine/cyclophosphamide lymphodepletion followed by 3 weekly doses of NKX019 on Day 0, 7, and 14 of a 28-day cycle. Combination cohorts (if opened) will additionally receive rituximab with each cycle.
NKX019
NKX019 is an investigational allogeneic CAR NK product targeting CD19 on cells. The starting dose of NKX019 in Part 1 is 3 × 10\^8 NK cells (6 × 10\^6/kg for patients \< 50 kg) administered as 3 weekly doses. Part 2 (dose expansion cohorts) will use the maximum tolerated dose (MTD) or recommended Phase 2 dose (RP2D) of NKX019 as determined in Part 1.

* Venetoclax for subjects with CLL/SLL
* Tyrosine kinase inhibitor for subjects with Philadelphia chromosome (Ph+) B-ALL
* Not responded or relapsed within 12 months of completion of their prior line of therapy, with the exception of a newly diagnosed Richter's transformation of CLL/SLL or other transformation of an indolent lymphoma, including from WM
