简介

近日,美国食品和药物管理局(FDA)已批准Kymriah™ (Tisagenlecleucel)静脉输注悬浮液(之前称为CTL019)—首个嵌合抗原受体T细胞(CAR-T)疗法用于治疗25岁以下、难治性或两次或多次复发的B细胞前体急性淋巴细胞白血病(ALL)患者。

Kymriah是新型免疫细胞疗法,也是一次性疗法,利用患者自身T细胞来对抗癌症。Kymriah是FDA批准的首个以基因转移为基础的疗法。复发或难治性(r/r) B细胞前体ALL患者预后一直不佳,因此急需能改善预后的新治疗选择。这些患者通常会接受包括化疗、放射、靶向疗法或干细胞移植在内的多种治疗,患者五年生存率不到10%。

Kymriah是创新型免疫细胞疗法,也是一次性疗法。该药物使用嵌合抗原受体内的4-1BB共刺激域来增强细胞扩增和持久性。

作用机制

KYMRIAH是CD19定向的遗传修饰的自体T细胞免疫疗法,其涉及用编码嵌合抗原受体(CAR)的转基因重编程患者自身的T细胞,以鉴定和消除表达CD19的恶性和正常细胞。CAR由鼠单链抗体片段组成,其识别CD19并与来自4-1BB(CD137)和CD3ζ的细胞内信号传导结构域融合。

CD3 zeta组分对于启动T细胞活化和抗肿瘤活性至关重要,而4-1BB增强了KYMRIAH的扩增和持久性。在与表达CD19的细胞结合后,CAR传递信号以促进T细胞扩增,活化,靶细胞消除和KYMRIAH细胞的持久性。

英文版说明

KYMRIAH(tisagenlecleucel) suspension for intravenous infusionIndicationKYMRIAH is a CD19-directed genetically modified autologous T cell immunotherapy indicated for the treatment of patients up to 25 years of age with B‑cell precursor acute lymphoblastic leukemia (ALL) that is refractory or in second or later relapse.Important Safety Information for KYMRIAH® (tisagenlecleucel)WARNING: CYTOKINE RELEASE SYNDROME AND NEUROLOGICAL TOXICITIESCytokine Release Syndrome (CRS), including fatal or life-threatening reactions, occurred in patients receiving KYMRIAH. Do not administer KYMRIAH to patients with active infection or inflammatory disorders. Treat severe or life-threatening CRS with tocilizumab, or tocilizumab and corticosteroidsNeurological toxicities, which may be severe or life-threatening, can occur following treatment with KYMRIAH, including concurrently with CRS. Monitor for neurological events after treatment with KYMRIAH. Provide supportive care as neededKYMRIAH is available only through a restricted program under a Risk eva luation and Mitigation Strategy (REMS) called the KYMRIAH REMSWarnings and PrecautionsCytokine Release Syndrome: CRS, including fatal or life-threatening reactions, occurred following treatment with KYMRIAH. CRS occurred in 54 (79%) of the 68 patients with relapsed or refractory (r/r) ALL receiving KYMRIAH, including ≥ grade 3 (Penn Grading System) in 33 (49%) of patients. The median time to onset of CRS in KYMRIAH trials was 3 days (range: 1-51), and in only 2 patients was onset after Day 10. The median time to resolution was 8 days (range: 1-36).Of the 54 patients with r/r ALL who had CRS, 27 (50%) received tocilizumab; 7 (13%) patients received 2 doses of tocilizumab, 3 (6%) patients received 3 doses of tocilizumab and 14 (26%) patients received addition of corticosteroids (eg, methylprednisolone).Five deaths occurred within 30 days of KYMRIAH infusion. One patient with r/r ALL died with CRS and progressive leukemia, 1 patient had resolving CRS with abdominal compartment syndrome, coagulopathy, and renal failure when an intracranial hemorrhage occurred. Among patients with r/r ALL who had CRS, key manifestations included fever (96%), hypotension (67%), hypoxia (20%), and tachycardia (30%). CRS may be associated with hepatic, renal, and cardiac dysfunction, and coagulopathy.Delay KYMRIAH infusion after lymphodepleting chemotherapy if patient has unresolved serious adverse reactions from preceding chemotherapies including pulmonary toxicity, cardiac toxicity, or hypotension, active uncontrolled infection, active graft vs host disease, or worsening of leukemia burden.Ensure that 2 doses of tocilizumab are available on-site prior to KYMRIAH infusion. Monitor patients for signs or symptoms of CRS 2 to 3 times during the first week, then for at least 4 weeks after treatment. Counsel patients to remain within proximity of the health care facility for at least 4 weeks following infusion and seek immediate medical attention should signs or symptoms of CRS occur at any time. At the first sign of CRS, immediately eva luate the patient for hospitalization and institute treatment with supportive care, tocilizumab, and/or corticosteroids as indicated.Risk factors for severe CRS are high pre-infusion tumor burden (≥50% blasts in bone marrow), uncontrolled or accelerating tumor burden following lymphodepleting chemotherapy, active infections, and/or inflammatory processes.Neurological Toxicities: Neurological toxicities, including severe or life-threatening reactions, occurred in 49 (72%) of the 68 patients with r/r ALL following treatment with KYMRIAH including ≥ grade 3 in 21% of patients. Among patients who had a neurological toxicity, 88% occurred within 8 weeks after KYMRIAH infusion. Median time to the first event was 6 days (range: 1-359) from infusion, and the median duration was 6 days for patients with r/r ALL. The onset of neurological toxicity can be concurrent with CRS, following resolution of CRS, or in the absence of CRS.The most common neurological toxicities observed in r/r ALL studies included headache (37%), encephalopathy (34%), delirium (21%), anxiety (13%), sleep disorders (10%), dizziness (6%), tremor (9%), and peripheral neuropathy (4%). Other manifestations included seizures, mutism and aphasia.Monitor patients for neurological events, specifically 2 to 3 times during the first week following KYMRIAH infusion, and exclude other causes for neurological symptoms. Provide supportive care as needed for KYMRIAH-associated neurological events.KYMRIAH REMS to Mitigate CRS and Neurological Toxicities: Because of the risk of CRS and neurological toxicities, KYMRIAH is available only through a restricted program under a Risk eva luation and Mitigation Strategy (REMS) called the KYMRIAH REMS. Further information is available at www.kymriah-rems.com or 1‑844‑4KYMRIAH (1-844-459-6742).Hypersensitivity Reactions: Allergic reactions may occur with KYMRIAH. Serious hypersensitivity reactions, including anaphylaxis, may be due to dimethyl sulfoxide or dextran 40 in KYMRIAH.Serious Infections: Infections, including life-threatening or fatal infections, occurred in 95 (55%) of 174 patients after infusion with KYMRIAH in clinical trials. Fifty-eight (33%) patients experienced grade ≥3 infections, including fatal infections in 2 (3%) patients with r/r ALL after KYMRIAH infusion. Prior to KYMRIAH infusion, infection prophylaxis should follow local guidelines. Patients with active uncontrolled infection should not start KYMRIAH treatment until the infection is resolved. Monitor patients for signs and symptoms of infection after treatment with KYMRIAH and treat appropriately.Febrile neutropenia (≥ grade 3) was also observed in 37% of patients with r/r ALL after KYMRIAH infusion and may be concurrent with CRS. In the event of febrile neutropenia, eva luate for infection and manage with broad spectrum antibiotics, fluids, and other supportive care as medically indicated.Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure, and death, can occur in patients treated with drugs directed against B cells. Perform screening for HBV, HCV, and HIV in accordance with clinical guidelines before cell collection for manufacturing.Prolonged Cytopenias: Patients may exhibit cytopenias for several weeks following lymphodepleting chemotherapy and KYMRIAH infusion. In patients with r/r ALL, ≥ grade 3 cytopenias not resolved by Day 28 following KYMRIAH treatment included neutropenia (40%) and thrombocytopenia (27%) among 52 responding patients. At 56 days following KYMRIAH, 17% and 12% of responding patients had ≥ grade 3 neutropenia or thrombocytopenia, respectively. Prolonged neutropenia has been associated with increased risk of infection. Myeloid growth factors, particularly GM-CSF, are not recommended during the first 3 weeks after KYMRIAH infusion or until CRS has resolved.Hypogammaglobulinemia: Hypogammaglobulinemia and agammaglobulinemia (IgG) can occur in patients with a complete remission after KYMRIAH infusion. Hypogammaglobulinemia was reported in 43% of patients with r/r ALL. Monitor immunoglobulin levels after treatment with KYMRIAH and manage using infection precautions, antibiotic prophylaxis, and immunoglobulin replacement standard guidelines.The safety of immunization with live viral vaccines during or following KYMRIAH treatment has not been studied. Vaccination with live virus vaccines is not recommended for at least 6 weeks prior to the start of lymphodepleting chemotherapy, during KYMRIAH treatment, and until immune recovery following treatment with KYMRIAH.Pregnant women who have received KYMRIAH may have hypogammaglobulinemia. Assess immunoglobulin levels in newborns of mothers treated with KYMRIAH.Secondary Malignancies: Patients treated with KYMRIAH may develop secondary malignancies or recurrence of their cancer. Monitor lifelong for secondary malignancies. If a second malignancy occurs, call 1‑844‑4KYMRIAH (1-844-459-6742) to obtain instructions on patient samples to collect for testing.Effects on Ability to Drive and Use Machines: Due to the potential for neurological events, including altered mental status or seizures, patients receiving KYMRIAH are at risk for altered or decreased consciousness or coordination in the 8 weeks following infusion. Advise patients to refrain from driving and engaging in hazardous occupations or activities, such as operating heavy or potentially dangerous machinery, during this initial period.Drug InteractionsHIV and the lentivirus used to make KYMRIAH have limited, short spans of identical genetic material (RNA). Therefore, some commercial HIV nucleic acid tests (NATs) may yield false positive results in patients who have received KYMRIAH.Pregnancy, Lactation, Females and Males of Reproductive PotentialNo data are available of KYMRIAH use in pregnant or lactating women. Therefore, KYMRIAH is not recommended for women who are pregnant or breastfeeding. Pregnancy after KYMRIAH administration should be discussed with the treating physician. Pregnancy status of females of reproductive potential should be verified with a pregnancy test prior to starting treatment with KYMRIAH. Report pregnancies to Novartis Pharmaceuticals Corporation at 1‑888‑669‑6682.Adverse ReactionsThe most common adverse reactions (>20%) in patients with r/r ALL were cytokine release syndrome, hypogammaglobulinemia, infections-pathogen unspecified, pyrexia, decreased appetite, headache, encephalopathy, hypotension, bleeding episodes, tachycardia, nausea, diarrhea, vomiting, viral infectious disorders, hypoxia, fatigue, acute kidney injury, edema, cough, and delirium.
