Informations complémentaires
Schéma : This is a single-arm, multi-cohort, multi-center, Phase 2 study to determine the efficacy and safety of JCAR017 (autologous T cells expressing anti-CD19 chimeric antigen receptor) in adult subjects with aggressive B-cell NHL. The study will enroll subjects in Europe and Japan with DLBCL NOS (de novo or tFL), high-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements with DLBCL histology (DHL/THL), FL3B, PCNSL and Richter's transformation. Subjects with secondary central nervous system (CNS) involvement are allowed.

Once enrolled subjects will undergo leukapheresis to enable JCAR017 cell product generation. Upon successful JCAR017 cell product generation, subjects will receive LD followed by infusion of JCAR017. JCAR017 will be administered at a dose of 1 x 10^8 JCAR017-positive transfected viable T cells by intravenous infusion.

Subjects will be followed for approximately 2 years after their JCAR017 infusion for safety, disease status, survival and health-related quality of life. Delayed adverse events following exposure to gene modified T cells will be assessed and long-term persistence of these modified T cells will continue to be monitored under a separate long-term follow-up protocol for up to 15 years after JCAR017 infusion as per competent authority guidelines.

Study arms:
Experimental: Administration of JCAR017
JCAR017 will be infused at a dose of 1 x 10^8 JCAR017-positive transfected viable T cells (5×10^7 CD8+ CAR+ T cells and 5×10^7 CD4+ CAR+ T cells), on Day 1 (2 to 7 days after completion of lymphodepleting chemotherapy [LD]).

Critères d'inclusion
Critères de non-inclusion
Critères d'inclusion et de non-inclusion
Critères d'inclusion : 1. Subject is ≥ 18 years of age at the time of signing the informed consent form (ICF).
2. Subject must understand and voluntarily sign an ICF prior to any study-related assessments/procedures being conducted.
3. Subject is willing and able to adhere to the study visit schedule and other protocol requirements.
4. Investigator considers the subject is appropriate for adoptive T cell therapy.
5. Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1 (Cohort 1, 4, 5 or 6). Subjects not eligible for transplant (TNE) with ECOG performance status 0, 1 or 2 may be enrolled in cohort 2 or 3 only, if they meet all other inclusion/exclusion criteria.
6. Subjects with one of the following:
# Cohort 1: Subjects with DLBCL NOS (de novo or tFL), high-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements with DLBCL histology (DHL/THL) and FL3B per WHO 2016 classification, after ≥ 2 lines of therapy*, including an anthracycline and rituximab (or other CD20-targeted agent).

# Cohort 2: Transplant not eligible subjects with DLBCL NOS (de novo or tFL), highgrade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements with DLBCL histology (DHL/THL) and FL3B per WHO 2016 classification, who failed first line therapy including an anthracycline and rituximab (or other CD20-targeted agent).
* Transplant not eligible subjects will include those who are deemed ineligible for high-dose chemotherapy and HSCT due to age, performance status or comorbidity. At the very least, subjects have to meet one of the following criteria: age ≥ 70 years, ECOG performance status ≥ 2, impaired pulmonary function (DLCO ≤ 60%), impaired cardiac function (LVEF < 50%), impaired renal function (CrCl < 60 mL/min) or impaired hepatic function (AST/ALT > 2x ULN, bilirubin > 2 mg/dL or cirrhosis Child-Pugh B or C).
* Subjects must fulfil all other in- and exclusion criteria.

# Cohort 3 (Japan only): Subjects meeting eligibility criteria for either Cohort 1 or 2.

# Cohort 4: Subjects with high-grade B-cell lymphoma with MYC and BCL2 and/or BCL6 rearrangements with DLBCL histology (DHL/THL) who failed first line therapy. Subjects may be screened at time of initial diagnosis and leukapheresis may be performed prior to initiation of first line therapy.

# Cohort 5: Subjects with PCNSL after ≥ 1 line of therapy, including high-dose methotrexate.

# Cohort 6: Subjects with Richter's transformation after ≥ 1 line of therapy for Richter's transformation.
* For subjects with transformed disease, the subject should have had at least 2 lines of systemic therapy for his/her transformed disease (ie, the DLBCL) for Cohort 1 and 1 line for Cohort 2 to be eligible. Lines of therapy do not include those given for a previously indolent condition (eg, follicular lymphoma). Subjects do NOT have to have anthracycline for their DLBCL if received for indolent disease.
Note: Subjects with secondary central nervous system (CNS) lymphoma involvement may enroll in Cohorts 1 to 4 and 6; subjects with PCNSL are eligible for Cohort 5. Subject selection must consider clinical risk factors for severe adverse events (AEs) and alternative treatment options. Subjects should only be enrolled if the Investigator considers the potential benefit outweighs the risk for the subject.

7. Histological confirmation of diagnosis at last relapse. Enough tumor material must be available for central confirmation of diagnosis, otherwise a new tumor biopsy is mandated.
NOTE: if the subject did not experience CR since last biopsy, the most recent biopsy will be considered adequate to participate. For subjects with PCNSL, at a minimum, corresponding pathology report is required if archival tumor material is not available and repeated biopsy not feasible.
8. For subjects with NHL and Richter's transformed CLL: Subject must have positron emission tomography (PET)-positive disease as per Lugano Classification.
9. For subjects with PCNSL: Subjects must have disease that is objectively measurable by International Workshop to Standardize Baseline Evaluation and Response Criteria in Primary Central Nervous System (CNS) Lymphoma, cerebrospinal fluid (CSF) cytology (in case of leptomeningeal only disease), or vitreal aspiration cytology and/or retinal photographs (in case of ocular lymphoma if clinically indicated).
10. Adequate organ function, defined as:
# Adequate bone marrow function to receive LD chemotherapy as assessed by the Investigator.
# Serum creatinine < 1.5 upper limit of normal (ULN) or creatinine clearance > 30 mL/min (estimated glomerular filtration rate [eGFR] by Cockroft-Gault).
# Alanine aminotransferase (ALT) ≤ 5 x ULN and total bilirubin < 2.0 mg/dL (or < 3.0 mg/dL for subjects with Gilbert's syndrome or lymphomatous infiltration of the liver).
# Adequate pulmonary function, defined as ≤ Grade 1 dyspnea according to Common Toxicity Criteria for Adverse Events (CTCAE) and SaO2 ≥ 92% on room air.
# Adequate cardiac function, defined as left ventricular ejection fraction (LVEF) ≥ 40% as assessed by echocardiogram or multigated acquisition (MUGA) scan performed within 4 weeks prior to leukapheresis.
11. Adequate vascular access for leukapheresis procedure.
12. Subjects must agree to not donate blood, organs, sperm or semen, and egg cells for usage in other individuals until at least 12 months after the JCAR017 infusion and until CAR T cells are no longer present by quantitative polymerase chain reaction (qPCR) on two consecutive tests, whichever occurs last.
13. Female subjects of childbearing potential (FCBP) must:
# Have two negative pregnancy tests as verified by the Investigator (one negative serum beta human chorionic gonadotropin [ß-hCG] pregnancy test result at screening and one negative serum pregnancy test within 48 hours prior to the first dose of LD chemotherapy). Subjects must agree to have another pregnancy test performed 90 days post JCAR017 infusion. This applies even if the subject practices true abstinence* from heterosexual contact.
# Either commit to true abstinence* from heterosexual contact (which must be reviewed on a monthly basis and source documented) or agree to use, and be able to comply with, effective contraception without interruption. Contraception methods must include 1 highly effective and 1 additional effective (barrier) method of contraception from screening until at least 12 months following JCAR017 infusion and until CAR T cells are no longer present by qPCR on two consecutive tests, whichever occurs last.
Note: Highly effective methods are defined as those that result in a low failure rate (ie, less than 1% per year) when used consistently and correctly. The following are examples of contraception:
Highly effective methods:
- Intrauterine device (IUD)
- Hormonal (birth control pill, injections, implants)
- Tubal ligation
- Partner's vasectomy
Additional effective methods:
- Male condom
- Diaphragm
- Cervical cap

# Agree to abstain from breastfeeding during study participation and for at least 90 days after JCAR017 infusion and until CAR T cells are no longer present by qPCR on two consecutive tests, whichever occurs last.

14. Male subjects must:
# Practice true abstinence* (which must be reviewed on a monthly basis and source documented) or agree to use a condom during sexual contact with a pregnant female or a female of childbearing potential while participating in the study and until at least 12 months following JCAR017 infusion even if he has undergone a successful vasectomy and until CAR T cells are no longer present by qPCR on two consecutive tests, whichever occurs last.
# True abstinence is acceptable when this is in line with the preferred and usual lifestyle of the subject. In contrast, periodic abstinence (eg, calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.

Critères de non-inclusion : 1. Subject has any significant medical condition, laboratory abnormality, or psychiatric illness that would prevent the subject from participating in the study.
