Brief Summary

This phase I trial tests the safety and effectiveness of pomalidomide after CD19 chimeric antigen receptor T-cell (CD19CART) therapy for the treatment of patients with CD19+ B-cell leukemias or lymphomas that have come back after a period of improvement (relapsed) or do not respond to treatment (refractory). Chimeric antigen receptor (CAR) T-cell therapy is a type of treatment in which a patient's T-cells (a type of immune system cell) are changed in the laboratory so they will attack cancer cells and are then re-infused into the patient. Following CAR T-cell infusion, CAR T-cells must expand and persist in the blood stream in order to most effectively treat leukemia/lymphoma. Pomalidomide stops the growth of blood vessels, stimulates the immune system, and may kill cancer cells. Research has shown that drugs like pomalidomide can modify the immune system and increase the number or improve the function of CAR T-cells in the blood. Pomalidomide may enhance the treatment effects of CAR T-cell therapy in patients who have received CD19CART therapy for relapsed or refractory CD19+ B-cell leukemia or lymphoma.

Conditions

Recurrent B Acute Lymphoblastic Leukemia; Recurrent B-Cell Non-Hodgkin Lymphoma; Refractory B Acute Lymphoblastic Leukemia; Refractory B-Cell Non-Hodgkin Lymphoma

Outcome Measures

Primary Outcomes (1)

• Incidence of adverse events

  Will assess the safety and tolerability of pomalidomide following CD19 chimeric antigen receptor T-cell (CD19CART) therapy for recurrent/refractory B-cell leukemia/lymphoma. Hematologic and non-hematologic toxicity within the first 56 days following the initiation of pomalidomide will be monitored. All observed toxicities, including dose-limiting toxicity will be summarized in terms of type (organ affected or laboratory determination), severity (by National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0), duration, and reversibility or outcome. Tables will be created to summarize toxicities.

  Within first 56 days following pomalidomide initiation

Secondary Outcomes (7)

• CD19CART transgene expression

  At days 0, 7, 14, 28, and 56

• CD19CART transgene expression

  At 1 year

• Overall survival

  Up to 1 year

• Event-free survival (EFS)

  Up to 1 year

• Duration of response

  Up to 1 year

Eligibility Criteria

• Absolute neutrophil count (ANC) \>= 750/mm\^3 (granulocyte colony stimulating factor allowed)
• Platelets \>= 50,000/mm\^3 (transfusion independent for \>= 7 days, defined as not receiving platelet transfusions for at least 7 days prior to enrollment, unless due to marrow involvement from primary malignancy \[thrombopoietin (TPO) mimetics allowed\])
• Total bilirubin =\< 1.5 x upper limit of normal (ULN) per institution
• Alanine aminotransferase (ALT \[serum glutamate pyruvate transaminase (SGPT)\]) =\< 3 x institutional ULN per institution

• Sexually active females capable of becoming pregnant and males must agree to participate in the pomalidomide Risk Evaluation and Mitigation Strategy (REMS) program
• Patients must agree not to donate blood during treatment with pomalidomide and for 4 weeks following discontinuation of the drug because the blood might be given to a pregnant female patient whose fetus must not be exposed to pomalidomide

You may not qualify if:

• Patients with known progressive or refractory disease.
• The following transplant or CAR T-related events are excluded:
• Active grade \>= 2 acute or chronic graft versus host disease (GVHD)
• Active cytokine release syndrome (CRS) grade \>= 2
• Active immune effector cell associated neurotoxicity (ICANS) grade \>= 2
• Subject receiving \>= 0.25 mg/kg/day of methylprednisolone equivalent. Subject being treated with medications with a known major drug interaction to pomalidomide. Specifically, patients receiving CYP1A2 inhibitors, such as ciprofloxacin, omeprazole, cimetidine, estrogen, and fluvoxamine.
• Patient who smokes cigarettes.
• Subject must not have initiated or received intervening therapy for a primary or secondary malignancy within 28 days of study enrollment, including, a) myelosuppressive chemotherapy, b) biologic anti-neoplastic agents (e.g., ruxolitinib, imatinib, dasatinib…), or checkpoint inhibitors (e.g., pembrolizumab). The use of cytokine inhibition for management of CRS/ICANS is allowed within the prior 28 days
• Receipt of radiation therapy (XRT) (focal or large field, including cranial or cranial-spinal) within 28 days prior to enrollment

• Patients with concomitant genetic syndromes associated with bone marrow failure states: such as patients with Fanconi anemia, severe congenital neutropenia, Schwachman syndrome or any other known bone marrow failure syndrome. Patients with Down syndrome are not excluded
