This phase I trial studies the side effects and best dose of TGFBR2 KO CAR27/IL-15 natural killer (NK) cells when given after chemotherapy in treating patients with lymphoid cancers that have come back after a period of improvement (relapsed)/that do not respond to treatment (refractory). TGFBR2 KO CAR27/IL-15 NK cells is a type of treatment in which natural killer cells from donor umbilical cord blood are changed in the laboratory so they will attack cancer cells. The NK cells are taken from the umbilical cord blood. Then the gene for a special receptor that binds to a certain protein on the patient’s cancer cells is added to the NK cells in the laboratory. The special receptor is called a chimeric antigen receptor. Giving chemotherapy before TGFBR2 KO CAR27/IL-15 NK cells helps kill cancer cells in the body and helps make room for the NK cells to work. Chemotherapy drugs, such as fludarabine and cyclophosphamide, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving TGFBR2 KO CAR27/IL-15 NK cells after chemotherapy may be safe, tolerable, and/or effective in treating patients with relapsed/refractory (R/R) lymphoid cancers.

PRIMARY OBJECTIVES:
I. To establish the safety of allogeneic TGFBR2 KO CAR27/IL-15-expressing NK cells (TGFBR2 KO CAR27/IL-15 NK cells) in patients with R/R lymphomas and B acute lymphoblastic leukemia (B-ALL) through the following primary endpoints:
Ia. To determine the recommended phase 2 dose (RP2D) of this treatment;
Ib. To define the dose-limiting toxicity (DLT) of this treatment.
SECONDARY OBJECTIVES:
I. To observe and record anti-tumor activity through the following secondary endpoints:
Ia. Day+ 30 complete response (CR) rate;
Ib. Day +30 overall response rate (ORR);
Ic. Day 180 progression-free survival rate.
II. To quantify the persistence of infused donor TGFBR2 KO CAR27/IL-15 NK cells in the recipient.
III. To conduct comprehensive immune reconstitution studies.
IV. To obtain preliminary data on quality of life (QOL) and patient experience.
OUTLINE: This is a dose-escalation study of TGFBR2 KO CAR27/IL-15 NK cells in combination with fludarabine and cyclophosphamide.
Patients receive fludarabine intravenously (IV) and cyclophosphamide IV on days -5 to -3 and TGFBR2 KO CAR27/IL-15 NK cells IV over 30 minutes on day 0 in the absence of disease progression or unacceptable toxicity. Patients who have either not responded to cycle 1 on day 30 or still have active lymphoma on day 90 will be considered for a second cycle of lymphodepleting chemotherapy and NK cells. Patients in CR after cycle 1 who experience relapse on follow-up will also be considered for a second cycle of lymphodepleting chemotherapy and NK cells. Additionally, patients undergo chest x-ray, echocardiography (ECHO) or multigated acquisition scan (MUGA), and computed tomography (CT) during screening. Patients also undergo positron emission tomography (PET)/CT, bone marrow aspiration and biopsy, and blood sample collection throughout the study.
After completion of study treatment, patients are followed up at days 7, 14, 28, and 56, months 3, 6, 9, 12, 15, 18, and 24, and then under companion protocol for up to 15 years.
