简介:

近日,美国FDA加速批准新药BESPONSA(inotuzumab ozogamicin)上市,治疗成人复发或难治性B细胞前体急性淋巴性白血病(B-cell precursor acute lymphoblastic leukemia)。值得一提的是,这是首款获得美国FDA批准的靶向CD22的抗体药物偶联物(ADC)。批准日期:2017年8月17日:公司:辉瑞(Pfizer)BESPONSA(奥英妥珠单抗[inotuzumab ozogamicin])注射用,用于静脉注射美国最初批准:2017年警告:肝毒性,包括肝脏VENO-OCCLUSIVE疾病(VOD)(也称为正常的阻塞性综合征,并且增加了造血后干细胞移植(HSCT)非复发性死亡的风险查看完整的盒装警告的完整处方信息。接受BESPONSA的患者发生肝毒性,包括致命和危及生命的VOD。接受BESPONSA的患者发生HSCT后非复发死亡率较高。

作用机制

Inotuzumab ozogamicin是CD22指导的抗体 – 药物偶联物(ADC)。 Inotuzumab识别人CD22。 小分子N-乙酰基-γ-加利车霉素是一种细胞毒性剂,通过接头与抗体共价连接。 非临床数据表明,inotuzumab ozogamicin的抗癌活性是由于ADC与表达CD22的肿瘤细胞的结合,然后是ADC-CD22复合物的内化,以及通过水解细胞内释放的N-乙酰基-γ-加利车霉素二甲基酰肼 连接子的切割。 N-乙酰基-γ-加利车霉素二甲基酰肼的活化诱导双链DNA断裂,随后诱导细胞周期停滞和凋亡细胞死亡。

适应症和用法

BESPONSA是CD22指导的抗体-药物偶联物(ADC),用于治疗患有复发或难治性B细胞前体急性淋巴细胞白血病(ALL)的成人。

奥英妥珠单抗英文版说明书

INOTUZUMAB OZOGAMICIN PFIZER INC 00008-0100-0FDA Approves BesponsaFDA Approves Besponsa (inotuzumab ozogamicin) for Relapsed or Refractory Acute Lymphoblastic LeukemiaU.S. Food and Drug Administration today approved Besponsa (inotuzumab ozogamicin) for the treatment of adults with relapsed or refractory B-cell precursor acute lymphoblastic leukemia (ALL).“For adult patients with B-cell ALL whose cancer has not responded to initial treatment or has returned after treatment, life expectancy is typically low,” said Richard Pazdur, M.D., director of the FDA’s Oncology Center of Excellence and acting director of the Office of Hematology and Oncology Products in the FDA’s Center for Drug eva luation and Research. “These patients have few treatments available and today’s approval provides a new, targeted treatment option.”B-cell precursor ALL is a rapidly progressing type of cancer in which the bone marrow makes too many B-cell lymphocytes, an immature type of white blood cell. The National Cancer Institute estimates that approximately 5,970 people in the United States will be diagnosed with ALL this year and approximately 1,440 will die from the disease.Besponsa is a targeted therapy that is thought to work by binding to B-cell ALL cancer cells that express the CD22 antigen, blocking the growth of cancerous cells.The safety and efficacy of Besponsa were studied in a randomized trial of 326 patients with relapsed or refractory B-cell ALL who had received one or two prior treatments. Patients were randomized to receive treatment with Besponsa or an alternative chemotherapy regimen. The trial measured the percentage of patients with no evidence of disease and full recovery of blood counts after treatment (complete remission or CR). Of the 218 eva luated patients, 35.8 percent who received Besponsa experienced CR for a median 8.0 months; of the patients who received alternative chemotherapy, 17.4 percent experienced CR for a median 4.9 months.Common side effects of Besponsa include low levels of platelets (thrombocytopenia), low levels of certain white blood cells (neutropenia, leukopenia), infection, low levels of red blood cells (anemia), fatigue, severe bleeding (hemorrhage), fever (pyrexia), nausea, headache, low levels of white blood cells with fever (febrile neutropenia), liver damage (transaminases and/or gamma-glutamyltransferase increased), abdominal pain and high levels of bilirubin in the blood (hyperbilirubinemia).The prescribing information for Besponsa includes a boxed warning that severe liver damage (hepatotoxicity), including blockage of veins in the liver (veno-occlusive disease [VOD] or sinusoidal obstruction syndrome), occurred in some patients who took Besponsa. If hepatotoxicity occurs, doctors should pause treatment or reduce the dose of Besponsa. If VOD occurs, patients should stop taking Besponsa and be given standard VOD treatment, if severe.The boxed warning also includes an increased risk of death for patients who take Besponsa after receiving a certain type of stem cell transplant.Other serious side effects of Besponsa include a decrease in blood cell and platelet production (myelosuppression), infusion-related reactions and problems with the heart’s electrical pulses (QT interval prolongation). Women who are pregnant or breastfeeding should not take Besponsa because it may cause harm to a developing fetus or a newborn baby.The FDA granted this application Priority Review and Breakthrough Therapy designations. Besponsa also received Orphan Drug designation, which provides incentives to assist and encourage the development of drugs for rare diseases.
