简要总结
This phase I trial studies the side effects and best dose of chimeric antigen receptor (CAR) T cells with a chlorotoxin tumor-targeting domain in treating patients with MPP2+ glioblastoma that has come back (recurrent) or that is growing, spreading, or getting worse (progressive). Vaccines made from a gene-modified virus may help the body build an effective immune response to kill tumor cells.
详细描述
PRIMARY OBJECTIVES:
I. Assess the feasibility and safety of dual delivery of chlorotoxin (EQ)-CD28-CD3zeta-CD19t-expressing CAR T-lymphocytes NCI SYs (chlorotoxin [CLTX]-CAR T cells) for participants with MMP2+ recurrent or progressive glioblastoma.
II. Determine the maximum tolerated dose schedule (MTD) and a recommended phase 2 dosing plan (RP2D) for dual delivery of CLTX-CAR T cells for participants with MMP2+ recurrent or progressive glioblastoma.
SECONDARY OBJECTIVES:
I. Describe persistence, expansion, and phenotype of endogenous and CLTX-CAR CAR T cells in tumor cyst fluid (TCF), peripheral blood (PB), and cerebrospinal fluid (CSF).

入选标准
- •Documented informed consent of the participant and/or legally authorized representative. Assent, when appropriate, will be obtained per institutional guidelines. Note: For research participants who do not speak English, a short form consent may be used with a COH certified interpreter/translator to proceed with screening and leukapheresis, while the request for a translated main consent is processed. However, the research participant is allowed to proceed with surgery/rickham placement and CAR T cell infusion only after the translated main consent form is signed.

- •Eastern Cooperative Oncology Group (ECOG) =< 2
- •Life expectancy >= 4 weeks
- •Participant has a prior histologically-confirmed diagnosis of a grade IV glioblastoma, or has a prior histologically-confirmed diagnosis of a grade II or III malignant brain tumors and now has radiographic progression consistent with a grade IV glioblastoma
- •Relapsed disease: radiographic evidence of recurrence/progression of measurable disease after standard therapy, and >= 12 weeks after completion of front-line radiation therapy
- •City of Hope (COH) Clinical Pathology confirms matrix metalloproteinase (MMP)2+ tumor expression by immunohistochemistry (>= 20% moderate/high MMP2 [2+/3+])
- •No known contraindications to leukapheresis, steroids, or tocilizumab
- •White blood cell (WBC) > 2000 /dl (or absolute neutrophil count [ANC] >= 1,000/mm^3) (to be performed within 14 days prior to leukapheresis unless otherwise stated)
- •Platelets >= 75,000/mm^3 (to be performed within 14 days prior to leukapheresis unless otherwise stated)
- •Hemoglobin >= 8 g/dl (to be performed within 14 days prior to leukapheresis unless otherwise stated)
- •Total bilirubin =< 1.5 upper limit of normal (ULN) (to be performed within 14 days prior to leukapheresis unless otherwise stated)
- •Aspartate aminotransferase (AST) =< 2.5 x ULN (to be performed within 14 days prior to leukapheresis unless otherwise stated)
- •Alanine aminotransferase (ALT) =< 2.5 x ULN (to be performed within 14 days prior to leukapheresis unless otherwise stated)
- •Serum creatinine =< 1.6 mg/dL (to be performed within 14 days prior to leukapheresis unless otherwise stated)
- •Oxygen (O2) saturation >= 95% on room air (to be performed within 14 days prior to leukapheresis unless otherwise stated)
- •Seronegative for human immunodeficiency virus (HIV) antigen (Ag)/antibody (Ab) combo (to be performed within 14 days prior to leukapheresis unless otherwise stated)
- •Women of childbearing potential (WOCBP): negative urine or serum pregnancy test (to be performed within 14 days prior to leukapheresis unless otherwise stated)
- •If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
- •Agreement by females and males of childbearing potential* to use an effective method of birth control or abstain from heterosexual activity for the course of the study through at least 3 months after the last dose of CAR T cells
- •Childbearing potential defined as not being surgically sterilized (men and women) or have not been free from menses for > 1 year (women only)
排除标准
- •Prior and concomitant therapies
- •Owing to higher frequency of wound-related complications, participants who are within 3 months of having received prior bevacizumab therapy at the time of enrollment are excluded.
- •Participant has not yet recovered from toxicities of prior therapy
- •Other illnesses or conditions
- •Uncontrolled seizure activity and/or clinically evident progressive encephalopathy
- •History of allergic reactions attributed to compounds of similar chemical or biologic composition to study agent

- •Active infection requiring antibiotics
- •Known history of immunodeficiency virus (HIV) or hepatitis B or hepatitis C infection
- •Other active malignancy

- •Noncompliance
- •Prospective participants who, in the opinion of the investigator, may not be able to comply with all study procedures (including compliance issues related to feasibility/logistics)
研究组 & 干预措施
Treatment (CAR T cell therapy) I
Arm 1 participants will undergo resection/biopsy of their tumor and placement of a Rickham catheter at the site of the resection/biopsy. Patients receive chlorotoxin (EQ)-CD28-CD3zeta-CD19t-expressing CAR T-lymphocytes NCI SYs via single delivery starting on day 0 for 3 weekly cycles over 28 days. Each treatment cycle begins with one CAR T cell infusion delivered intracranial intratumoral or intracavitary [ICT] and lasts for 1 week. Beginning 1 week after cycle 3, patients may continue with CAR T cell treatment per principal investigator and patient discretion. Treatment continues in the absence of disease progression or unacceptable toxicity.
干预措施: Chlorotoxin (EQ)-CD28-CD3zeta-CD19t-expressing CAR T-lymphocytes (via ICT delivery) (Biological)
Treatment (CAR T cell therapy) II
Arm 2 participants will undergo resection/biopsy of their tumor and placement of a Rickham catheter at the site of the resection/biopsy and the lateral ventricle. Patients receive chlorotoxin (EQ)-CD28-CD3zeta-CD19t-expressing CAR T-lymphocytes NCI SYs via dual delivery starting on day 0 for 3 weekly cycles over 28 days. Each treatment cycle begins with two CAR T cell infusions (intracranial intratumoral or intracavitary [ICT]) and also into the lateral ventricle (intracranial intraventricular [ICV]) and lasts for 1 week. Beginning 1 week after cycle 3, patients may continue with CAR T treatment per principal investigator and patient discretion. Treatment continues in the absence of disease progression or unacceptable toxicity.
