   1. Creatinine ≤ 1.6 mg/dl

5. Evidence of active disease. This could include circulating disease in the blood, disease in the bone marrow by standard morphology (or by MRD testing for ALL patients), or measurable disease per Lugano Criteria (NHL patients).
6. Male or female age ≥ 18 years.
7. ECOG Performance Status that is either 0 or 1.
8. Subjects of reproductive potential must agree to use acceptable birth control methods.
9. Disease-specific criteria:

   a. Cohort A i. Patients with relapsed or refractory B cell ALL which meets one of the following criteria:

<!-- -->

1. Relapsed or refractory B cell ALL with 2nd or greater relapse or refractory to 1st salvage as defined by:

   a. Recurrent disease in the blood or bone marrow identified morphologically, by immunohistochemistry or by Flow cytometry.

   b. Patients with extramedullary relapse only (no bone marrow involvement) will be eligible if disease response can be assessed radiographically, OR
2. Refractory B cell ALL as defined by:

   a. Failure to achieve remission (\<5% bone marrow blasts) after 2 cycles of induction chemotherapy b. Patients that achieve morphologic remission but remain MRD+ after ≥2 cycles of induction chemotherapy, OR
3. Ph+ relapsed or refractory B cell ALL that is intolerant to or have failed a tyrosine kinase inhibitor therapy containing regimen.

ii. Patients with prior or current history of CNS3 disease\* will be eligible only if CNS disease is responsive to therapy (at infusion, must meet criteria in Section 5.2) 1. \*CNS disease definitions70:

a. CNS1 - no blasts seen on cytocentrifuge (CNS negative); b. CNS2 - total nucleated cell count \<5x106/L, but blasts seen on cytocentrifuge; c. CNS3 - total nucleated cell count 5x106/L with blasts on cytocentrifuge and/or signs of CNS leukemia (i.e. cranial nerve palsy).

b. Cohort B (CLL) i. Patients must have relapsed/refractory disease after at least 2 prior lines of appropriate therapy, AND ii. Patients must have previously received, or be intolerant to an approved BTK inhibitor and venetoclax; unless a BTK inhibitor or venetoclax is contraindicated.

c. Cohort B (NHL)- With one of the following diagnoses: i. Diffuse Large B-cell Lymphoma

1. Patients with any of the following histologies:

   1. Diffuse large B-cell lymphoma (DLBCL), NOS

   i. Germinal center B-cell type ii. Activated B-cell type b. Primary cutaneous DLBCL, leg type c. Primary mediastinal (thymic) large B-cell lymphoma d. ALK+ large B-cell lymphoma e. High-grade B-cell lymphoma, with MYC and BCL2 and/or BCL6 rearrangements (i.e. "Double or Triple Hit") f. High-grade B-cell lymphoma, NOS
2. Patients must have relapsed after, or be ineligible for, prior CAR T cell therapy, and meet one of the following criteria:

   1. Relapsed/refractory disease after at least 2 prior lines of appropriate therapy and are ineligible for autologous stem cell transplant or commercial CAR T cell therapy.
   2. Relapse/refractory disease after autologous SCT.
   3. Relapsed/refractory disease after allogeneic SCT. ii. Large cell transformation of CLL (Richter's transformation)

1\. Patients must be primary refractory or received at least 1 prior line of treatment.

iii. Follicular lymphoma 1. Patients who have received at least 2 prior lines of appropriate therapy (not including single agent monoclonal antibody therapy), AND 2. Progressed within 2 years after second or higher line of therapy. iv. Mantle cell lymphoma

1. Patients must have either failed or be ineligible for standard of care Tecartus™ (brexucabtagene autoleucel) or other investigational CAR T cell product; and
2. Patients must also meet one of the following criteria:

   1. Relapsed/refractory disease after at least 2 prior lines of appropriate therapy, including a BTK inhibitor. Single-agent monoclonal antibody therapy does not count towards prior lines of therapy.
   2. Relapsed/refractory disease after prior autologous SCT.
   3. Relapsed/refractory disease after prior allogeneic SCT..

Exclusion Criteria:
