3. Subject is willing and able to adhere to the study visit schedule and other protocol requirements

4. Diagnosis of B-cell Acute Lymphoblastic Leukemia (ALL)

5. Evidence of CD19 expression via flow cytometry (peripheral blood or bone marrow) or immunohistochemistry (bone marrow biopsy)

6. Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2

7. No contraindications to cyclophosphamide. This includes subjects with:

• hypersensitivity to cyclophosphamide, any of its metabolites
• acute infections
• bone marrow aplasia or bone marrow depression prior to treatment
• urinary tract infection
• acute urothelial toxicity from cytotoxic chemotherapy or radiation therapy
• urinary outflow obstruction
• obstruction

8. Adequate organ function, defined as:

a. Serum creatinine ≤ 1.5 × age-adjusted upper limit of normal (ULN) OR calculated creatinine clearance (Cockcroft and Gault) > 30 mL/min/1.73 m2 b. Alanine aminotransferase (ALT) ≤ 5 × ULN and direct bilirubin < 2.0 mg/dL (or < 3.0 mg/dL for subjects with leukemic infiltration of the liver) c. Adequate pulmonary function, defined as ≤ Grade 1 dyspnea and oxygen saturation (SaO2) ≥ 92% on room air d. Adequate cardiac function, defined as left ventricular ejection fraction (LVEF) ≥ 40% as assessed by echocardiogram (ECHO) or multiple uptake gated acquisition (MUGA) performed within 1 month of signing the informed consent form

9. Adequate central or peripheral vascular access for leukapheresis procedure. For subjects requiring central venous catheter (CVC) placement, a surgical consultation indicating subject eligibility for CVC placement is sufficient for enrollment.

10. Subjects must agree to not donate blood, organs, sperm or semen, and egg cells for usage in other individuals without recipient knowledge about exposure to a genetically modified organ by the donor and having been informed about the potential risks associated with it at any point after receiving JCAR015 infusion.

11. Females of childbearing potential (FCBP1) must:

a. Have two negative pregnancy tests as verified by the Investigator (one negative serum beta human chorionic gonadotropin (ß-hCG) pregnancy test result within 7 days prior to the first dose of cytoreductive chemotherapy (Part A screening evaluation), and one negative serum or urine pregnancy test at the Part B screening evaluation prior to first JCAR015 infusion). She must agree to have another pregnancy test 90 days post final JCAR015 dose. This applies even if the subject practices true abstinence2 from heterosexual contact.

b. Either commit to true abstinence2 from heterosexual contact (which must be reviewed on a monthly basis and source documented) or agree to use, and be able to comply with, effective contraception without interruption. Contraception methods must include 1 highly effective and 1 additional effective (barrier) method of contraception from at least 28 days prior to JCAR015 initial infusion and during the study therapy including dose interruptions. Cessation of contraception after this point should be discussed with a responsible physician. Note: Highly effective methods are defined as those that result in a low failure rate (ie, less than 1% per year) when used consistently and correctly. The following are examples of highly effective and additional effective methods of contraception:

• Intrauterine device (IUD)

• Hormonal (birth control pill, injections, implants)

• Tubal ligation

• Partner's vasectomy

• Male Condom (additional effective method)

• Diaphragm (additional effective method)

• Cervical Cap (additional effective method) c. Agree to abstain from breastfeeding during study participation and for at least 90 days after the last dose of JCAR015.

d. Agree to use highly effective methods of contraception during the entire study period (Part A through 12 months after the final JCAR015 infusion).

12. Males who have partners of childbearing potential must agree to use an effective barrier contraceptive method during the entire study period (Part A through 12 months after the final JCAR015 infusion).
