This phase I/II trial tests the safety and effectiveness of extramedullary disease (EMD)-directed external beam radiation therapy (EBRT) in combination with talquetamab for the treatment of multiple myeloma patients with extramedullary disease. Extramedullary disease in multiple myeloma involves the infiltration of organs and soft tissues by malignant plasma cells and has proven difficult to treat. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink cancers. EBRT is a type of radiation therapy that delivers high-energy beams to the cancer from outside of the body. In this trial, the EBRT will be directed to a site of extramedullary disease. Talquetamab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens). Combining EMD-directed EBRT with talquetamab may be safe, tolerable, and/or effective in treating multiple myeloma patients with extramedullary disease.

Nursing Considerations for the Clinical Management of Adverse Events Associated with Talquetamab in Patients with Relapsed or Refractory Multiple Myeloma

Review

作者: Leahey, Sheryl ; Hefner, Kayla ; Rogers, Stephanie ; Gray, Kathleen ; O'Rourke, Lisa ; Tolbert, Jaszianne ; Esler, Elaine ; Ray, Chloe ; Shenoy, Samantha ; Purcell, Kiah ; Catamero, Donna ; Renaud, Thomas ; Hannemann, Linda ; Patel, Saurabh

OBJECTIVESTalquetamab is a newly approved bispecific antibody targeting the CD3 receptor on T cells and a receptor, G protein-coupled receptor family C group 5 member D (GPRC5D), highly expressed on multiple myeloma (MM) cells. In addition to immune therapy-related adverse events (AEs) associated with bispecific antibody therapies, talquetamab is associated with unique skin/nail and oral GPRC5D-related side effects that require additional supportive care. This review provides clinical management strategies for talquetamab based on oncology nurses' experience during the MonumenTAL-1 (NCT03399799/NCT04634552) clinical trial. The objective of this review is to raise awareness among nurses and patients to better understand and manage the side effects associated with talquetamab treatment in order to optimize patient outcomes.DATA SOURCESMonumenTAL-1 is a phase 1/2 clinical trial of talquetamab in patients with relapsed/refractory MM who are triple-class exposed. Details on overall response, safety, and AE incidence and occurrence were previously published. Management strategies for the T-cell-related and unique GPRC5D-related AEs were collected from oncology nurses from different study sites.CONCLUSIONTalquetamab has shown overall response rates of >71% in patients with relapsed/refractory MM in the MonumenTAL-1 study. AEs were low grade and predictable; few led to study discontinuation.IMPLICATIONS FOR NURSING PRACTICEOncology nurses have specialized knowledge of treatment administration monitoring based on their participation in the MonumenTAL-1 trial. This review provides information for nurses in both the academic and community settings on how to monitor, counsel, and support patients, which will in turn improve patients' quality of life and overall survival.

Bispecific Antibody Use in Patients With Lymphoma and Multiple Myeloma

Review

作者: Braun, Adam ; Minnema, Monique C ; Gouni, Sushanth ; Pulles, Astrid ; Strati, Paolo ; Budde, Lihua E

This article endeavors to navigate the clinical journey of bispecific antibodies (BsAbs), from elucidating common toxicities and management strategies to examining novel agents and broadening access in community health care. These drugs, commonly through T-cell activation, result in shared adverse events such as cytokine release syndrome and immune effector cell-associated neurotoxicity syndrome. Variations in target antigens and designs, however, might introduce unique toxicities for different BsAbs, warranting specific management approaches. Recent US Food and Drug Administration approvals of BsAbs targeting CD3+ T cells linked to CD20 for non-Hodgkin lymphoma and to B-cell maturation antigen or GPRC5D for multiple myeloma have transformed the treatment landscape for hematologic malignancies. Emerging new agents promise further enhancement and safety, exploring novel antigen targets, innovative structures such as trispecific antibodies, and the engagement of diverse immune cells. Simultaneously, the expansion of BsAbs into community practices is underway, demanding a multifaceted strategy that encompasses educational initiatives, operational adaptations, and collaborative frameworks. This ensures comprehensive treatment access, allowing every patient, irrespective of geographical or socioeconomic status, to benefit from these advancements in cancer therapy.

Recent advances and future perspectives of T-cell engagers in lymphoid malignancies

Article

作者: Shirouchi, Yuko ; Maruyama, Dai

AbstractBispecific antibodies (BsAbs) are monoclonal antibodies that simultaneously bind to a specific antigen on tumors and CD3 on T cells, leading to T cell activation and subsequent tumor cell lysis. Several CD20 × CD3 BsAbs are being developed for B-cell lymphomas. Furthermore, multiple clinical trials to evaluate BsAbs for the treatment of multiple myeloma, with targets including BCMA, GPRC5D and FcRH5, are ongoing. Emerging evidence suggests promising efficacy in heavily pretreated patients with relapsed or refractory lymphoid malignancies, showing an overall response rate of 50–60%, with complete response rates of 30–40% for relapsed or refractory large B-cell lymphoma and 60–70% for relapsed or refractory multiple myeloma. Their toxicity profiles are generally consistent with other T-cell redirecting therapies, including cytokine release syndrome, which may be mitigated with several strategies, such as step-up dosing, pre-mediation with glucocorticoids and a subcutaneous route of administration, and very rare neurotoxicity. Several clinical trials evaluated BsAbs in combination with other agents or in earlier lines of treatment, including in front-line settings. BsAbs have the potential to change the treatment paradigm of lymphoid malignancies in the coming years; however, longer follow-ups are required to assess the durability of responses to these agents. We herein provide an overview of the findings of recent clinical trials on BsAbs, including mechanisms of action, safety profiles, and efficacy, and discuss the role of BsAbs in the treatment of B-cell lymphomas and multiple myeloma.

自免热潮下：逆势翻盘的biotech们

▎Armstrong 近两年来MNC纷纷扫货自免产品，包括单抗、双抗、TCE、CAR-T等，这股热潮也蔓延至资本市场，一些历经波折的biotech有了逆风翻盘的机会。 Alpine Alpine Immune成立于2015年，早期核心管线为CD28/ICOS拮抗剂，但临床开发并不顺利，肿瘤管线同样推进不顺利。最近几年，Alpine的核心管线才转为TACI-Fc融合蛋白Povetacicept，今年即将推进到三期临床。 Alpine Immune的市值长期徘徊在10亿美元左右，伴随着自免风口的到来，今年4月，Vertex以49亿美元收购Alpine。 TCE：Cullinan、同润生物、恩沐生物 TCE领域的B细胞靶向CD3双抗，原本主要用于血液瘤，在资本市场上关注度并不高。随着CD19 CAR-T在自免领域的开拓性探索，行业开始高度关注TCE在自免领域的潜力。Cullinan Oncology的核心管线CD3/CD19双抗，率先在今年4月宣布转战自免赛道，并很快完成2.8亿美元增发募资。同时，Cullinan Oncology将名字也直接改成了Cullinan Therapeutics。同润生物的首发管线同样为CD3/CD19双抗CN201，同润生物在2018年完成1.5亿美元A轮融资，此后未再融过资。今年8月，默沙东以7亿美元引进同润生物的CN201。根据CN201今年ASCO会议上汇报了血液瘤的一期临床数据，其中5mg以上剂量对于FL/MCL/MZL/SLL的ORR达到100%。安全性方面，CRS发生率为7%，且均为1级或2级，同时没有神经毒性。恩沐生物成立于2016年，首发管线CMG1A46为一款CD3/CD19/CD20三抗，如今推进到血液瘤一期临床阶段。恩沐生物的融资并不算顺利，2021年A+轮融资后，与博锐生物做过一次授权合作，此后近三年无新的融资。前不久，恩沐生物完成主流美元基金Foresite Capital的新一轮融资，并一起推动了昨日与葛兰素史克的授权合作，后者以3亿美元预付款+5.5亿美元的价格引进了CMG1A46的全球权益。总结虽然自免风口带来了新的机会，但也要看到真正实现逆风翻盘的，还是那些分子设计上具有显著差异化优势，并且经过初步临床验证的biotech。Alpine的Povetacicept亲和力远高于Vera的Atacicept和荣昌生物的泰它西普，并经过二期临床验证。同润生物的CN201安全性优势显著，且B细胞淋巴瘤疗效显著。恩沐生物的CMG1A46同时覆盖CD19、CD20两个经过验证的B细胞靶点，且为活性更强的2+1价态设计。 Armstrong技术全梳理系列 GPRC5D靶点全梳理； CD40靶点全梳理； CD47靶点全梳理；补体靶向药物技术全梳理；补体药物：眼科治疗的重要方向； Claudin 6靶点全梳理； Claudin 18.2靶点全梳理；靶点冷暖，行业自知；中国大分子新药研发格局；被炮轰的“me too”；佐剂百年史；胰岛素百年传奇； CUSBEA：风雨四十载；中国新药研发的焦虑；中国生物医药企业的研发竞争；中国双抗竞争格局；中国ADC竞争格局；中国双抗技术全梳理；中国ADC技术全梳理； Ambrx技术全梳理； Vir Biotech技术全梳理； Immune-Onc技术全梳理；亘喜生物技术全梳理；康哲药业技术全梳理；科济药业技术全梳理；恺佧生物技术全梳理；同宜医药技术全梳理；百奥赛图技术全梳理；腾盛博药技术全梳理；创胜集团技术全梳理；永泰生物技术全梳理；中国抗体技术全梳理；德琪医药技术全梳理；德琪医药技术全梳理2.0；和铂医药技术全梳理；荣昌生物技术全梳理；再鼎医药技术全梳理；药明生物技术全梳理；恒瑞医药技术全梳理；豪森药业技术全梳理；正大天晴技术全梳理；吉凯基因技术全梳理；基石药业技术全梳理；百济神州技术全梳理；百济神州技术全梳理第2版；信达生物技术全梳理；信达生物技术全梳理第2版；中山康方技术全梳理；复宏汉霖技术全梳理；先声药业技术全梳理；君实生物技术全梳理；嘉和生物技术全梳理；志道生物技术全梳理；道尔生物技术全梳理；尚健生物技术全梳理；康宁杰瑞技术全梳理；科望医药技术全梳理；科望医药技术全梳理2.0；岸迈生物技术全梳理；礼进生物技术全梳理；康桥资本技术全梳理；余国良的抗体药布局；荃信生物技术全梳理；安源医药技术全梳理；三生国健技术全梳理；仁会生物技术全梳理；乐普生物技术全梳理；同润生物技术全梳理；宜明昂科技术全梳理；派格生物技术全梳理；迈威生物技术全梳理； Momenta技术全梳理； NGM技术全梳理；普米斯生物技术全梳理；普米斯生物技术全梳理2.0；三叶草生物技术全梳理；贝达药业抗体药全梳理；泽璟制药抗体药全梳理；恒瑞医药抗体药全梳理；齐鲁制药抗体药全梳理；石药集团抗体药全梳理；豪森药业抗体药全梳理；华海药业抗体药全梳理；科伦药业抗体药全梳理；百奥泰技术全梳理；凡恩世技术全梳理。
