Brief Summary
This is a single center, open-label, phase 1 study to determine the safety and feasibility of infusing CART22-65s with or without huCART19 after administration of lymphodepleting chemotherapy in adult patients with relapsed or refractory B-ALL.

Eligibility Criteria
You may qualify if:
- \- 1. Patients with relapsed or refractory B cell ALL:
- a. Patients with 2nd or greater relapse or refractory to 1st salvage as defined by: i. Recurrent disease in the bone marrow identified morphologically, by immunohistochemistry or by Flow cytometry.
- ii. Patients with extramedullary relapse only (no bone marrow involvement) will be eligible if disease response can be assessed radiographically b. Patients with refractory disease as defined by: i. Failure to achieve remission (\<5% bone marrow blasts) after 2 cycles of induction chemotherapy ii. Patients that achieve remission but remain MRD+ after ≥2 cycles of induction chemotherapy.
- c. Patients with Ph+ ALL are eligible provided they are intolerant to or have failed tyrosine kinase inhibitor therapy.
- d. Patients with prior or current history of CNS3 disease\* will be eligible only if CNS disease is responsive to therapy.
- i. \*CNS disease definitions:
- CNS1 - no blasts seen on cytocentrifuge (CNS negative);
- CNS2 - total nucleated cell count \<5x106/L, but blasts seen on cytocentrifuge;
- CNS3 - total nucleated cell count 5x106/L with blasts on cytocentrifuge and/or signs of CNS leukemia (i.e. cranial nerve palsy).
- \. For Cohort 1: Documentation of CD22 expression on malignant cells at relapse. For Cohort 2: Documentation of CD22 and/or CD19
- \. Adequate vital organ function defined as:
- Creatinine ≤ 1.6 mg/dl
- ALT/AST ≤ 3x upper limit of normal range
- Total or Direct bilirubin ≤ 2.0 mg/dl. If Total bilirubin is ≤2.0, Direct bilirubin does not need to be assessed.
- Left Ventricle Ejection Fraction (LVEF) ≥ 40% confirmed by ECHO/MUGA
- +4 more criteria
You may not qualify if:
- \. Active hepatitis B or active hepatitis C.
- \. HIV Infection.
- \. Class III/IV cardiovascular disability according to the New York Heart Association Classification.
- \. Subjects with clinically apparent arrhythmia or arrhythmias who are not stable on medical management within two weeks of eligibility confirmation by physician-investigator.
- \. Active acute or chronic graft-versus-host disease (GVHD) requiring systemic therapy.
- \. Planned concurrent treatment with systemic steroids or immunosuppressant medications. Patients may be on a stable low dose of steroids (\<10mg equivalent of prednisone) for chronic respiratory conditions or adrenal insufficiency. For additional details regarding use of steroid and immunosuppressant medications.
- \. CNS3 disease that is progressive on therapy, or with CNS parenchymal lesions that might increase the risk of CNS toxicity.
- \. Pregnant or nursing (lactating) women.
- \. Patients with a known history or prior diagnosis of optic neuritis or other immunologic or inflammatory disease affecting the central nervous system.
