This research study is a Pilot Study, which is the first time investigators are examining
this intervention in people with primary central nervous system lymphoma.
- The name of the study intervention is tisagenlecleucel. Tisagenlecleucel is an
investigational treatment that uses the participants own immune cells, called T cells,
to try to kill the cancerous cells
- The research study procedures include screening for eligibility and study treatment
including, leukapheresis, evaluations, and follow up visits.
- The study treatment will be one day and participants will be followed for up to 2 years.
- It is expected that about 6 people will take part in this research study
Inclusion Criteria:
Primary CNS Lymphoma in high risk elderly patients
- New diagnosis of primary CNS lymphoma.
- Voluntarily sign informed consent form(s)
- ≥60 years of age at the time of signing informed consent
- Eastern Cooperative Oncology Group (ECOG) performance status 0 - 2
- Have failed or are unable to tolerate definitive first-line methotrexate based therapy
as defined by:
- Grade 3+ AKI and/or transaminitis preventing repeat treatment exposure and/or,
- Failure to achieve a complete response (per IPCG) following two cycles of first
line therapy,
--- Definitive first-line therapies must include high dose methotrexate-based
therapy but may also include temozolomide, high dose cytarabine, pemetrexed,
lenalidomide, ibrutinib and rituximab.
- Whole-brain irradiation, lenalidomide monotherapy and ibrutinib monotherapy are
considered first line therapy if patient was not eligible for methotrexate-based
chemotherapy at time of initial treatment but now meets study eligibility
criteria.
- Adequate absolute lymphocyte count (ALC > 500 cells/ul) within one week of apheresis.
- Adequate bone marrow function defined by absolute neutrophil count (ANC) >1000
cells/mm3without growth factor support, and untransfused platelet count >50,000 mm3
within 7 days.
- Left ventricular ejection fraction >40%
- Adequate hepatic function defined by aspartate aminotransferase (AST) and/or alanine
aminotransferase (ALT) <2.5 × upper limit of normal (ULN) and direct bilirubin <1.5 ×
ULN
- Adequate renal function defined by creatinine clearance >30 ml/min using the
Cockcroft-Gault formula
- International ratio (INR) or partial thromboplastin time (PTT) <1.5 × ULN, unless on a
stable dose of anticoagulant for a thromboembolic event.
- The effects of tisagenlecleucel T cells on the developing human fetus are unknown. For
this reason, women of child-bearing potential and men with partners of childbearing
potential must agree to use adequate contraception (hormonal or barrier method of
birth control; abstinence) prior to leukapheresis for at least 1-year post
tisagenlecleucel infusion and until CAR T cells are no longer present by qPCR on two
consecutive tests. Should a woman become pregnant or suspect she is pregnant while she
or her partner is participating in this study, she should inform her treating
physician immediately. Men with partners of childbearing potential treated or enrolled
on this protocol must also agree to use adequate contraception prior to leukapheresis
and until 4 months after tisagenlecleucel T cells administration.
- Ability and willingness to adhere to the study visit schedule and all protocol
requirements
Relapsed/Refractory Primary CNS Lymphoma
- Diagnosis of relapsed/refractory PCNSL having received at least one prior line of CNS
directed therapy.
- Voluntarily sign informed consent form(s)
- ≥18 years of age at the time of signing informed consent
- Eastern Cooperative Oncology Group (ECOG) performance status 0-2
- Adequate absolute lymphocyte count (ALC > 500 cells/ul) within one week of apheresis.
- Adequate bone marrow function defined by absolute neutrophil count (ANC) >1000
cells/mm3without growth factor support, untransfused platelet count >50,000 mm3, and
untransfused hemoglobin >9 g/dL.
- Left ventricular ejection fraction >40%
- Adequate hepatic function defined by aspartate aminotransferase (AST) and/or alanine
aminotransferase (ALT) <2.5 × upper limit of normal (ULN) and direct bilirubin <1.5 ×
ULN
- Adequate renal function defined by creatinine clearance >30 ml/min using the
Cockcroft-Gault formula
- International ratio (INR) or partial thromboplastin time (PTT) <1.5 × ULN, unless on a
stable dose of anticoagulant for a thromboembolic event.
- The effects of tisagenlecleucel T cells on the developing human fetus are unknown. For

Inclusion Criteria for Lymphodepletion/Cell Infusion:
- No Active, uncontrolled, systemic bacterial, viral, or fungal infection.
- Adequate renal function defined by creatinine clearance >30 ml/min using the
Cockcroft-Gault formula
Exclusion Criteria:
- Prior treatment with an any investigational cellular therapy.
- Ongoing treatment with chronic immunosuppressants (e.g., cyclosporine). Systemic
steroids are allowed up to a dose of dexamethasone 4mg daily or equivalent.
- Ongoing systemic immunosuppression for acute and/or chronic GVH as a result of
previous allogeneic bone marrow transplant.
- Significant co-morbid condition or disease which in the judgment of the Principal
Investigator would place the subject at undue risk or interfere with the study;
examples include, but are not limited to, cirrhotic liver disease, sepsis, and/or
recent significant traumatic injury.
- Active, uncontrolled, systemic bacterial, viral, or fungal infection.
- Active hepatitis B or hepatitis C infection.
- HIV infection.
- Subjects with a history of class III or IV congestive heart failure or non- ischemic
cardiomyopathy.
- Subjects with second malignancies if the second malignancy has required therapy in the
last 3 years or is not in complete remission; exceptions to this criterion include
successfully treated non-metastatic basal cell or squamous cell skin carcinoma, or
prostate cancer that does not require therapy other than hormonal therapy.
- Pregnant or lactating women
- Live virus vaccines within 2 weeks prior to planned start of lymphodepleting
chemotherapy.
