Exclusion Criteria:

* Autologous transplant within 6 weeks of planned CAR-T cell infusion
* Allogeneic stem cell transplant or donor lymphocyte infusion within 2 months of planned CAR-T cell infusion and patients must be off immunosuppressive agents. Patients with live vaccines given 28 days prior to lymphodepletion (LD) chemotherapy will be excluded
* Active graft versus host disease
* Active central nervous system or meningeal involvement by lymphoma or leukemia. Subjects with untreated brain metastases/central nervous system (CNS) disease will be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events. Patients with a history of CNS or meningeal involvement must be in a documented remission by CSF evaluation and contrast-enhanced magnetic resonance imaging (MRI) imaging for at least 90 days prior to registration
* Active malignancy, other than non-melanoma skin cancer or carcinoma in situ (e.g.cervix, bladder, breast). Patients with a prior or concurrent malignancy whose natural history or treatment does not have the potential to interfere with the safety or efficacy assessment of the investigational regimen are eligible for this trial (e.g.

Low Gleason score prostate Cancer)

* A minimum of 28 days must have elapsed between prior treatment with investigational agent(s) and the day of lymphocyte collection
* Human immunodeficiency virus (HIV)-seropositive patients are allowable, however must be on effective anti-retroviral therapy with undetectable viral load within 6 months of enrollment to be eligible for this trial
* Subjects with uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, pulmonary abnormalities or psychiatric illness/social situations that would limit compliance with study requirements
* Pregnant or breastfeeding women are excluded from this study because CAR-T cell therapy may be associated with the potential for teratogenic or abortifacient effects. Women of childbearing potential must have a negative serum pregnancy test. Because there is an unknown, but potential risk for adverse events in nursing infants secondary to treatment of the mother with CAR-T cells, breastfeeding should be discontinued. These potential risks may also apply to other agents used in this study
* Evidence of myelodysplasia or cytogenetic abnormality indicative of myelodysplasia on any bone marrow biopsy prior to initiation of therapy
* Patients with a positive hepatitis B core antibody or surface antigen are at high risk for hepatitis B virus (HBV) reaction and will require entecavir/tenofivir prophylaxis or serial hepatitis B (Hep B) PCR monitoring at the direction of an infectious disease specialist. Duration of prophylaxis to correspond with detection of Anti-CD19/20/22 CAR T cells/viral vector copies in serum or continued evidence of B-cell aplasia such as reduced intravenous immunoglobulin therapy (IVIG) levels. No antiviral prophylaxis is indicated with hepatitis C positivity with negative PCR
* Patients with history of clinically relevant CNS pathology such as epilepsy, seizure disorders, paresis, aphasia, uncontrolled cerebrovascular disease, severe brain injuries, dementia and Parkinson's disease
* History of autoimmune disease (i.e. rheumatoid arthritis, systemic lupus erythematosus) with requirement of immunosuppressive medication within 6 months
* Live vaccines given in 28 days prior to lymphodepleting chemotherapy

This phase I trial tests the safety, side effects and best infusion dose of genetically engineered cells called anti-CD19/CD20/CD22 chimeric antigen receptor (CAR) T-cells following a short course of chemotherapy with cyclophosphamide and fludarabine in treating patients with lymphoid cancers (malignancies) that have come back (recurrent) or do not respond to treatment (refractory). Lymphoid malignancies eligible for this trial are: non-Hodgkin lymphoma (NHL), acute lymphoblastic leukemia (ALL), chronic lymphocytic leukemia (CLL), and B-prolymphocytic leukemia (B-PLL). T-cells (a type of white blood cell) form part of the body's immune system. CAR-T is a type of cell therapy that is used with gene-based therapies. CAR T-cells are made by taking a patient's own T-cells and genetically modifying them with a virus so that they are recognized by a group of proteins called CD19/CD20/CD22 which are found on the surface of cancer cells. Anti-CD19/CD20/CD22 CAR T-cells can recognize CD19/CD20/CD22, bind to the cancer cells and kill them. Giving combination chemotherapy helps prepare the body before CAR T-cell therapy. Giving CAR-T after cyclophosphamide and fludarabine may kill more tumor cells.
