- •a) Active Disease
- •(1) Clinically suspected or documented relapse/progression, in first or second relapse following at least one cycle of an asparaginase-based chemotherapy regimen OR (2) Initial disease or first or second relapse and unable to tolerate one full cycle of asparaginase-based chemotherapy regimen OR b) High-risk disease (stage III/IV, KPI groups 3-4 or IPI intermediate-high) prior to second CR regardless of previous chemotherapy.
- •Male or female ≥ 18 years of age.
- •Weigh ≥ 35 kg.
- •ECOG performance score 0-2, inclusively.
- •Negative β-hCG test in women of childbearing potential.
- •Able to understand and comply with the requirements of the study and to provide written informed consent.
排除标准
- •CNS lymphoma.
- •NK cell leukemia.
- •Hemophagocytic lymphohistiocytosis.
- •Positive for HIV, hepatitis B, hepatitis C, syphilis or human T Cell leukemia virus (HTLV).
- •Use of systemic corticosteroids >0.5 mg/kg/day within 10 days prior to obtaining 200 mL whole blood starting material.
- •Patient is pregnant or lactating.
- •Active second malignancy.
- •Any prior allogeneic hematopoietic stem cell or solid organ transplant.
- •Asparaginase refractory disease, defined by any one of the following:
- •Progression at any time during initial asparaginase based chemotherapy and up to 3 months after end of initial asparaginase based chemotherapy, OR
- •Failure to achieve at least PR with initial asparaginase based chemotherapy.
- •Absolute lymphocyte count (ALC) <400/µL.
- •Any previous autologous EBV specific T cell treatment.
- •Systemic fungal, bacterial, viral or other infection that is not controlled.
- •Third or greater relapse.
- •FOR TREATMENT PHASE:
- •Inclusion Criteria:
- •Documented relapse or progression following at least one prior cycle of an asparaginase-containing chemotherapy regimen.
- •Active disease based on any one of the following present at the baseline study visit or within two weeks prior to the baseline study visit:
- •Imaging (may use local imaging)
- •Clinical sign(s) including skin lesions consistent with lymphoma, organ dysfunction or organomegaly not attributable to other causes; or other clinical sign(s)
- •Detectable blood or plasma ENV DNA (may use local laboratory)
- •Completed most recent course of chemotherapy at least 2 weeks prior to first study drug dose.
- •Recovery from acute hematological, hepatic and renal chemotherapy-related toxicities as defined by ≤ Grade 1 according to NCI CTCAE v4.
- •Life expectancy ≥ 8 weeks.
- •Exclusion Criteria:
- •Use of any investigational agents within prior 4 weeks.
- •Radiotherapy within prior 3 weeks.
- •Major surgery within prior 2 weeks.
- •Systemic corticosteroids within 24 hours prior to study drug administration.
- •Evidence of hepatic dysfunction based on serum total bilirubin >3 times upper limit of normal (ULN), or ALT >5 times ULN or AST >5 times ULN.
研究组 & 干预措施
baltaleucel-T
Treatment consists of 2 infusions of 2x10E7 cells/m2 given on Days 1 and 15 intravenously via a peripheral or central line over a 1 to 10 minute period.
Subjects who tolerate the study treatment well and who do not require treatment with an alternative chemotherapeutic agent will be eligible for up to 3 additional infusions of 2x10E7 cells/m2 administered at week 8, month 3 and month 6.
