入组条件决定能不能参加

不限性别 · ≥ 18 Years

纳入标准:

* 必须患有复发或难治性非霍奇金淋巴瘤(NHL)(A组 - NHL/CLL)、慢性淋巴细胞白血病(A组 - NHL/CLL)或急性淋巴细胞白血病(B组 - ALL),且已接受至少两线治疗。疾病必须在末次方案治疗后进展,或在末次方案治疗后未能达到完全缓解。
* 受试者的恶性肿瘤为CD19阳性,通过末次可用活检组织的免疫组织化学或流式细胞术分析,或针对循环疾病的外周血检测确认。
* 东部肿瘤协作组(ECOG)体能状态 ≤ 2
* 总胆红素 ≤ 1.5倍机构正常值上限,除非胆红素升高由Gilbert综合征(最高2倍正常值)或非肝脏来源所致
* AST(SGOT)≤ 3倍机构正常值上限
* ALT(SGPT)≤ 3倍机构正常值上限
* 血清肌酐 ≤ 2倍机构正常值上限,且肌酐清除率 ≥ 30 mL/min(计算值或实测值)
* 必须具有足够的肺功能,定义为室内空气下脉搏血氧饱和度 ≥ 92%。
* 最近一次超声心动图显示左心室射血分数≥ 40%,即心功能良好。
* 绝对淋巴细胞计数 >100/微升 (uL)
* 参与者(或法定监护人)必须有能力理解并愿意签署书面知情同意书。
* 对于有生育能力的女性:同意在治疗期间以及人抗CD19 CAR-T细胞输注后至少90天内保持禁欲(避免异性性交)或使用年失败率< 1%的避孕方法。如果女性已月经初潮,尚未达到绝经后状态(连续闭经< 12个月,且除绝经外无其他明确原因),且未接受过手术绝育(切除卵巢和/或子宫),则认为其有生育能力。年失败率< 1%的避孕方法示例包括双侧输卵管结扎、男性绝育、抑制排卵的激素避孕药、释放激素的宫内节育器和含铜宫内节育器。禁欲的可靠性应根据临床试验的持续时间以及患者首选和通常的生活方式进行评估。周期性禁欲(例如,日历法、排卵法、症状体温法或排卵后法)和体外射精是不可接受的避孕方法。
* 男性:同意禁欲(避免异性性交)或使用避孕措施,并同意避免捐精,定义如下:对于有生育能力的女性伴侣,男性必须在治疗期间以及人源抗CD19 CAR-T细胞输注后至少6个月内保持禁欲,或使用避孕套加上一种额外的避孕方法,共同使年失败率< 1%。男性在此期间必须避免捐精。对于怀孕的女性伴侣,男性必须在治疗期间以及人源抗CD19 CAR-T细胞输注后至少6个月内保持禁欲或使用避孕套,以避免潜在的胚胎或胎儿暴露。性禁欲的可靠性应根据临床试验的持续时间以及患者首选和通常的生活方式进行评估。周期性禁欲(例如,日历法、排卵期法、症状体温法或排卵后法)和体外射精是不可接受的避孕方法

排除标准:

* 计划CAR-T细胞输注前6周内接受过自体移植。
* 计划CAR-T细胞输注前3个月内接受过异基因干细胞移植,且患者必须已停用免疫抑制剂。
* 活动性移植物抗宿主病。
* 淋巴瘤或白血病活动性中枢神经系统或脑膜受累。未经治疗的脑转移/中枢神经系统(CNS)疾病受试者将被排除在本临床试验之外,因其预后差,且常出现进行性神经功能障碍,会干扰神经系统及其他不良事件的评估。
* 有CNS或脑膜受累史的受试者,必须在入组前至少90天内通过脑脊液(CSF)评估和增强MRI成像记录为缓解。
* 除非黑色素瘤皮肤癌或原位癌(如宫颈、膀胱、乳腺)外的第二活动性恶性肿瘤。
* 既往接受研究性药物治疗与淋巴细胞采集日之间必须至少间隔28天。
* HIV血清阳性。
* 患有未控制的并发疾病,包括但不限于持续或活动性感染、有症状的充血性心力衰竭、不稳定型心绞痛、心律失常、肺部异常或精神疾病/社会状况,这些情况会限制对研究要求的依从性。
* 孕妇或哺乳期妇女被排除在本研究之外,因为CAR-T细胞治疗可能与致畸或堕胎效应的潜在风险相关。有生育潜力的女性必须具有阴性的血清妊娠试验。由于母体接受CAR-T细胞治疗后,哺乳婴儿可能存在未知但潜在的不良事件风险,因此应停止哺乳。这些潜在风险也可能适用于本研究中使用的其他药物。
* 筛选期骨髓活检显示有骨髓增生异常或提示骨髓增生异常的细胞遗传学异常的证据
* 反映活动性乙型或丙型肝炎感染的血清学状态。乙型肝炎核心抗体、乙型肝炎表面抗原(HBsAg)或丙型肝炎抗体阳性的患者,入组前必须聚合酶链反应(PCR)阴性。(PCR阳性患者将排除。)
* 有临床相关中枢神经系统病理史,如癫痫、惊厥性疾病、瘫痪、失语、未控制的脑血管疾病、严重脑损伤、痴呆和帕金森病。
* 有自身免疫性疾病史(即类风湿关节炎、系统性红斑狼疮),且6个月内需要免疫抑制药物治疗。

Inclusion Criteria:

* Must have relapsed or refractory non-Hodgkin lymphoma (NHL) (Group A - NHL/CLL), chronic lymphocytic leukemia (Group A - NHL/CLL) or acute lymphoblastic leukemia (Group B - ALL) treated with at least two lines of therapy. Disease must have either progressed after the last regimen or presented failure to achieve complete remission with the last regimen.
* The participant's malignancy is CD19 positive, either by immunohistochemistry or flow cytometry analysis on the last biopsy available or peripheral blood for circulating disease.
* Eastern Cooperative Oncology Group (ECOG) Performance status ≤ 2
* Total bilirubin ≤ 1.5 times the institutional upper limit of normal unless bilirubin rise is due to Gilbert's syndrome (maximum 2 time normal) or of non-hepatic origin
* AST (SGOT) ≤ 3 times institutional upper limit of normal
* ALT (SGPT) ≤ 3 times institutional upper limit of normal
* Serum Creatinine ≤ 2 times the institutional upper limit of normal and creatinine clearance ≥ 30 mL/min (calculated or measured)
* Must have adequate pulmonary function as defined as pulse oximetry ≥ 92% on room air.
* Must have adequate cardiac function as defined as left ventricular ejection fraction≥ 40% in the most recent echocardiogram.
* Absolute Lymphocyte Count \>100/microliter (uL)
* Participants (or legal guardians) must have the ability to understand and the willingness to sign a written informed consent document.
* For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use a contraceptive method with a failure rate of \< 1% per year during the treatment period and for at least 90 days after the human anti-CD19 CAR-T cell infusion. A woman is considered to be of childbearing potential if she is postmenarcheal, has not reached a postmenopausal state (\< 12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus). Examples of contraceptive methods with a failure rate of \< 1% per year include bilateral tubal ligation, male sterilization, hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices. The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception.
* For men: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures, and agreement to refrain from donating sperm, as defined below: With female partners of childbearing potential, men must remain abstinent or use a condom plus an additional contraceptive method that together result in a failure rate of \< 1% per year during the treatment period and for at least 6 months after the human anti-CD19 CAR-T cell infusion. Men must refrain from donating sperm during this same period. With pregnant female partners, men must remain abstinent or use a condom during the treatment period and for at least 6 months after the human antiCD19 CAR-T cell infusion to avoid potential embryonal or fetal exposure. The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods

Exclusion Criteria:

* Autologous transplant within 6 weeks of planned CAR-T cell infusion.
* Allogeneic stem cell transplant within 3 months of planned CAR-T cell infusion and patients must be off immunosuppressive agents.
* Active graft versus host disease.
* Active central nervous system or meningeal involvement by lymphoma or leukemia. Subjects with untreated brain metastases/central nervous system (CNS) disease will be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events.
* Participants with a history of CNS or meningeal involvement must be in a documented remission by cerebrospinal fluid (CSF) evaluation and contrast-enhanced MRI imaging for at least 90 days prior to registration.
* Second active malignancy, other than non-melanoma skin cancer or carcinoma in situ (e.g. cervix, bladder, breast).
* A minimum of 28 days must have elapsed between prior treatment with investigational agent(s) and the day of lymphocyte collection.
* HIV seropositivity.
* Participants with uncontrolled intercurrent illness including, but not limited to ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, pulmonary abnormalities or psychiatric illness/social situations that would limit compliance with study requirements.
* Pregnant or breastfeeding women are excluded from this study because CAR-T cell therapy may be associated with the potential for teratogenic or abortifacient effects. Women of childbearing potential must have a negative serum pregnancy test. Because there is an unknown, but potential risk for adverse events in nursing infants secondary to treatment of the mother with CAR-T cells, breastfeeding should be discontinued. These potential risks may also apply to other agents used in this study.
* Evidence of myelodysplasia or cytogenetic abnormality indicative of myelodysplasia on screening bone marrow biopsy prior
* Serologic status reflecting active hepatitis B or C infection. Patients that are positive for hepatitis B core antibody, hepatitis B surface antigen (HBsAg), or hepatitis C antibody must have a negative polymerase chain reaction (PCR) prior to enrollment. (PCR positive patients will be excluded.)
* Participants with history of clinically relevant CNS pathology such as epilepsy, seizure disorders, paresis, aphasia, uncontrolled cerebrovascular disease, severe brain injuries, dementia and Parkinson's disease.
* History of autoimmune disease (i.e. rheumatoid arthritis, systemic lupus erythematosus) with requirement of immunosuppressive medication within 6 months.
