Redirected Auto T Cells for Advanced Myeloma

The primary objective of this study is to evaluate the safety and tolerability of autologous
genetically modified T cells. Genetic material is transferred into the subject's previously
harvested autologous T cells to redirect them to target myeloma cells rather than their usual
target. Study subjects must have systemic or multifocal myeloma requiring autologous stem
cell transplantation whose disease has relapsed or incompletely responded to prior therapy or
have high-risk features. Subjects must also have measureable disease on study entry, as
defined by quantifiable or detectable levels of serum or urine paraprotein or elevated serum
free light chains with an abnormal ratio.

Inclusion Criteria:

- Myeloma has relapsed, progressed, or failed to respond after at least one prior course
of therapy (consisting of at least 2 treatment cycles or months of therapy)

- Myeloma has responded partially to initial therapy but a complete response
(immunofixation negative and normal serum free light chain) has NOT developed after a
minimum of 3 cycles or months of initial therapy

- Myeloma has high-risk features as defined by the presence of one or more cytogenetic
abnormalities known to confer a poor outcome even after standard auto-transplants:
complex karyotype (≥ to 3 abnormalities), t(4;14), t(14;16), del (17) (p13.1), and/or
chromosome 13 abnormalities. These patients may be enrolled even while in complete or
near-complete remission

- Measurable disease on study entry, as defined by quantifiable or detectable levels of
serum or urine paraprotein or elevated serum free light chains with abnormal ratio

- Patients who are in complete remission at the time of proposed study entry (serum and
urine immunofixation consistently negative and normal serum free light chains) are not
eligible unless their disease meets the criteria for high-risk as defined in protocol

- Ages 18-80

- ECOG performance status 0-2 (unless due solely to bone pain)

- Prior to Lenalidomide maintenance phase, all study participants must be registered
into the mandatory RevAssist® program, and be willing and able to comply with the
requirements of RevAssist®

- Females subjects of childbearing potential must have a negative pregnancy test and
both male and female (of childbearing potential) subjects must agree to use reliable
methods of contraception during the study.

- Lenalidomide treatment phase: able to take aspirin (81 or 325 mg) daily as
prophylactic anticoagulation (patients intolerant to ASA may use warfarin or low
molecular weight heparin)

- HLA-A201 patients must have confirmed expression of NY-ESO-1 and/or LAGE. HLA-A2
patients must have the A-201 allele

Adequate vital organ function as defined below:

- Serum creatinine ≤3.0 mg/dl and not on dialysis

- WBC at least 3000/mm³, platelet count at least 100,000/mm³

- SGOT ≤ to 2 x upper limit of normal and bilirubin ≤ to 2.0 mg/dl (unless due to
Gilbert's syndrome)

- Left ventricular ejection fraction (LVEF) ≥ 45%. A lower LVEF is permissible if a
formal cardiologic evaluation reveals no evidence for clinically significant
functional impairment

- Adequate pulmonary function with mechanical parameters ≥ 40% predicted (FEV1, FVC,
TLC, DLCO). Patients who are unable to complete PFTs due to bone pain or fracture must
have a high resolution CT scan of the chest and must have acceptable arterial blood
gases defined as a room air PO2 greater than 70 mmHg

- Patients should have recovered from any toxicities related to prior therapy or at
least returned to their baseline level of organ function.

- Patients should be off of glucocorticoids for at least 2 weeks and/or other therapies
for at least 1 week prior to enrollment

Exclusion Criteria:

- Pregnant or nursing females

- HIV or HTLV-1/2 seropositivity

- History of myelodysplasia

- History of chronic active hepatitis or liver cirrhosis (if suspected by laboratory
studies, should be confirmed by liver biopsy)

- Active Hepatitis B (as defined by positive Hepatitis B surface antigen); positive
Hepatitis C virus (HCV) antibody is NOT an exclusion

- Prior allogeneic transplant

- History of severe autoimmune disease requiring steroids or other immunosuppressive
treatments

- Active immune mediated diseases including: connective tissue diseases, uveitis,
sarcoidosis, inflammatory bowel disease, multiple sclerosis

- Evidence or history of other significant cardiac, hepatic, renal, ophthalmologic,
psychiatric, or gastrointestinal disease which would likely increase the risks of
participating in the study

- Active bacterial, viral, or fungal infections
