`
`Phase 1 / Pilot
`
`Open-label approach
`
`Approximately 4-5 years
`
`Single-center
`
`The primary objective is to determine the safety and survival of the
`redirected autologous T cells transduced with the anti-CD19 lentiviral
`vector (referred to as “CART-19” cells).
`
`10 subjects
`
`Inclusion criteria are designed to include adult patients aged >18 with
`CD19+ B cell malignancies with no available curative treatment options
`(such as autologous or allogeneic stem cell transplantation) who have
`limited prognosis (several months to <2 year survival) with currently
`available therapies.
`
`CART-19 cells transduced with a lentiviral vector to express either anti-
`CD19 scFv:TCRζ or anti-CD19 scFv TCRζ:41BB, administered by i.v.
`injection as a using a “split dose” (total dose of ~2x109 – 5 x1010 T
`cells) approach to dosing: 10% on day 0, 30% on day 1 and 60% on day
`2. A second dose of CART-19 cells (~2.5 x109 – 5 x108 T cells) will be
`given administered by i.v. injection on day 11 to those patients who
`have sufficient CART-19 cells available.
`
`Approximately 20 minutes; drug is expected to persist at detectable
`levels in circulation for 2 to 6 weeks.
`
`None. This protocol will be given to subjects with unmet medical needs
`for which there are no effective therapies known at this time.

`
`The statistical analysis will be primarily descriptive in keeping with the
`exploratory nature of the study. Descriptive statistics will be applied to
`determine the relative engraftment, persistence and trafficking of the
`study drug components to blood and optionally bone marrow / lymph
`node. All adverse events will be described and exact 95% confidence
`intervals will be produced for adverse event rates, both overall and
`within major categories. The change in the ratio of CART-19 cells over
`time will be compared using a Wilcoxon signed-rank test for paired
`data. This nonparametric test is very efficient (>95%) compared to the
`t-test if the underlying data are normally distributed. Analysis of other
`secondary endpoints such as anti-tumor activity will also be primarily
`descriptive and may include summary statistics such as means and
`standard deviations or Kaplan-Meier curves for survival information.

`1 Introduction
`This document is a protocol for a human research study. This study is to be conducted according
`to US and international standards of Good Clinical Practice (FDA Title 21 part 312 and
`International Conference on Harmonization guidelines), applicable government regulations and
`Institutional research policies and procedures.
`
`1.1 Background
`CD19 positive hematologic malignancies. B cell malignancies comprise a heterogeneous group
`
`of neoplasms including a vast majority of non-Hodgkin's lymphomas (NHL), as well as acute
`lymphoblastic leukemias (ALL) and chronic lymphocytic leukemias (CLL). An estimated 87,000
`new cases of leukemia and non-Hodgkin’s lymphomas are diagnosed in the US annually2, and
`most of these are of B cell origin. Current treatments for B cell malignancies include
`chemotherapy, radiation therapy, bone marrow transplantation, and peripheral blood stem cell
`transplantation. Despite these treatment modalities, most patients will remain incurable.
`B lineage acute leukemia (B-ALL) is responsive to chemotherapy, however the ability to
`uniformly eradicate the disease has not been achieved, as about 65% of adults and 20% of
`children have disease recurrence 3, 4. Improved response rates have thus far only been achieved
`with
`intensified cytotoxic chemotherapy, resulting
`in substantial morbidity. Adoptive
`immunotherapy with allogeneic donor leukocytes has potent anti-leukemic effects, however the
`benefit is confined largely to patients with myeloid leukemias, as B-ALL has a durable remission
`rate of less than 10% 5, and often at the cost of substantial morbidity due to GVHD6, 7.
`
`Adoptive immunotherapy. Adoptive transfer is a term coined by Medawar8 to study
`allograft
`rejection, and
`the
`term adoptive
`immunotherapy denotes
`the
`transfer of
`infectious disease9. Adoptive
`immunocompetent cells for
`the
`treatment of cancer or
`immunotherapy appears to be the most robust form of immunotherapy for treatment of
`established tumors10. However, several problems remain to be solved before this therapy
`becomes routine; see our reviews for details11, 12.
`
`CD19 as a therapeutic target for leukemia and lymphoma. CD19 is a 95kDa glycoprotein
`
`present on B cells from early development until differentiation into plasma cells13-15. It is a
`member of the immunoglobulin (Ig) superfamily and a component of a cell surface signal
`transduction complex that regulates signal transduction through the B cell receptor15-17. Mice
`lacking CD19 have a decreased number of B cells in peripheral lymphoid tissues, a decreased B
`cell response to oral vaccines and mitogens, and decreased serum Ig levels15, 18. Expression of
`CD19 is restricted to B lineage cells and is not expressed by pluripotent blood stem cells19. CD19
`is also expressed by most B cell lymphomas, mantle cell lymphoma, ALLs, CLLs, hairy cell
`leukemias, and a subset of acute myelogenous leukemias13, 20, 21. CD19 thus represents a highly
`attractive target for immunotherapy19. Furthermore, CD19 is not present on most normal tissues,
`other than normal B cells, including pluripotent blood stem cells19, which makes CD19 a
`relatively safe target presenting a minimal risk of autoimmune disease or irreversible
`myelotoxicity. Anti-CD19 antibodies and scFvs either native or conjugated to radioisotopes or
`toxins are currently being developed and have demonstrated promise in both mouse models22-26
`and human and non-human primates27-37.

`
`The
`Engineered T cells with redirected specificity: chimeric immune receptors (CIR).
`daunting task of breaking tolerance to self antigens is the major obstacle facing the field of
`cancer immunotherapy. This can be difficult or impossible if the TCR repertoire has been deleted
`or rendered non functional by various post thymic tolerance mechanisms38, 39. One strategy is to
`identify therapeutically effective T cell clones, clone the heterodimeric TCR, and express it in
`other T cells, creating bispecific T cells with reactivity against the original TCR and the cloned
`TCR (reviewed in40-42). This was first carried out using protoplast fusion to transfer the TCR
`genes from a mouse T cell into another mouse T cell clone with a different specificity43. Other
`labs used cell fusion or electroporation to transfer TCR genes44, 45, and in these cases
`demonstrated that MHC restricted specificity could be transferred. The advent of retroviral
`vectors made it possible to make this process more efficient. The Pease laboratory first used a
`retroviral vector with the LTR directing expression of TCRζ and an internal CMV promoter
`driving TCRα expression in mouse T cells46, 47. In 1999 Clay used a retroviral vector to transfer
`an HLA-A2 restricted TCR with specificity for MART-1, derived from tumor infiltrating
`lymphocytes, from a melanoma patient to T cells from 3 normal donors48. Recently Kessels and
`coworkers demonstrated that redirected mouse T cells were fully functional, could protect
`against tumor challenge, and could treat established metastasis49. The T cells were shown to
`expand dramatically (by more than 3 logs) after in vivo antigen encounter, and they trafficked to
`tumor sites.
`An alternative strategy to produce genetically engineered T cells is the ‘T-body’ or
`chimeric antigen receptor (CAR) approach, which uses genetically programmed, patient-derived
`lymphocytes transfected with chimeric receptor genes to combine the effector functions of T
`lymphocytes with the ability of antibodies to recognize predefined surface antigens with high
`specificity in a non-MHC restricted manner50, 51. These receptors have the ability to recognize
`intact membrane proteins independent of antigen processing. CARs or T-bodies typically encode
`an extracellular domain to bind tumor or virus linked to an intracellular signaling domain that
