This drug can be used with bendamustine and rituximab to treat DLBCL, if the lymphoma has come back after receiving two other treatments. It is a little bit confusing because, in theory, we could use [belantamab mafodotin] in the second- or third-line settings. Whether you want to learn about treatment options, get advice on coping with side effects, or have questions about health insurance, were here to help. To me, this is the most exciting area because it is a one-and-done [approach] versus continued therapy. To mitigate adverse events, dose steps were implemented, which were again hampered by disease progression.17,18 Novel half-lifeextended constructs (CD19 HLE BiTE) and full-size antibodies have entered clinical trials with improved pharmacokinetics. It is an ADC where the antibody is directed against BCMA and is conjugated to a chemotherapy drug. Practice Guidelines in Oncology: B-cell Lymphomas. Immunotherapy is treatment that either boosts the patients own immune system or uses man-made versions of the normal parts of the immune system to kill lymphoma cells or slow their growth. We are not sure if they will be covered by third-party carriers. National Comprehensive Cancer Network (NCCN). The extent of BCMA positivity may be higher or lower for individual patients, but because they are all positive, BCMA serves as a very efficient target for BCMA-directed therapies. The vast majority of them are using BCMA as the target, but that is not the only target that is available. The antibody acts like a homing signal, bringing the chemo drug to lymphoma cells, where it enters the cells and kills them. Mosunetuzumab (Lunsumio) is a type of antibody known as a bispecific T-cell engager (BiTE). Over recent years, bispecific antibodies have been engineered in >50 different formats, including dual-affinity retargeting proteins, tandem diabodies, and bi-nanobodies, but in oncology, the bispecific T-cell engagers (BiTEs) are the most developed and thus are the focus of this article.1 Both BiTE and CAR approaches are independent of the specificity of the endogenous T-cell receptor and independent of major histocompatibility complex on tumor cells. Chimeric antigen receptor (CAR)-T cell therapy has been revolutionary as it has produced remarkably effective and durable clinical responses 1. In that sense, the BiTE platform offers more flexibility in choosing and changing the targeting domain compared with the CAR T platform, thereby enabling individualized targeting strategies during the course of the disease. David H. Vesole, MD, PhD, discusses the evolution of multiple myeloma treatment, and explained how other BCMA-therapies are poised to impact clinical practice. 2) in that they can: 1) redirect specific polyclonal immune cells such as T cells and NK cells to tumor cells to enhance tumor killing, 2) simultaneously block two different pathways with unique or overlapping functions in pathogenesis, 3) potentially increase binding specificity by Although they share a common antigen target in the B-cell lineage surface protein CD19, they differ in their intracellular costimulatory domain (4-1BB vs CD28). most of these therapies can be given with the prolongation of life, without negatively impacting QOL a great deal.. The authors declare that they have no competing interests. Pan et al27 demonstrated in a small pediatric BCP-ALL population the feasibility of sequentially administering CD19 CAR T cells followed by CD22 CAR T cells. Other side effects can include low blood cell counts (with an increased risk of bleeding and serious infections), feeling tired or weak, loss of appetite, diarrhea, cough, fever, and swelling in the hands or legs. The drug does not [elicit] an overly robust response rate as a single agent. T-cell Transfer Therapy - Immunotherapy - NCI - National Cancer Institute After 29 months, the median event-free survival time was 6.1 months; however, in the subgroup of MRD-positive patients, that figure rose to 10.6 months. Whereas both these platforms use single-chain variable fragments to recognize and target antigens expressed on tumor cells, the BiTE platform also uses one to recognize and bind T cells.2, Tisagenlecleucel (tisa-cel) and axicabtagene ciloleucel (axi-cel) are the 2 CAR T-cell therapies currently approved by the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA) to treat adult patients with relapsed/refractory (r/r) B-cell malignancies. Loncastuximab tesirine (Zynlonta):This antibody-drug conjugateis used by itself to treat some types of large B-cell lymphoma (including diffuse large B-cell lymphoma, or DLBCL) after at least 2 other treatments (not including surgery or radiation) have been tried. How has the treatment of multiple myeloma evolved? Brentuximab vedotin (Adcetris) is an anti-CD30 antibody attached to a chemotherapy drug (an antibody-drug conjugate). The induction and consolidation therapies were 6-week cycles consisting of 4 weeks on and 2 weeks off, whereas the maintenance therapy was 4 weeks for every 12 weeks. Amandeep Godara, MBBS, of @huntsmancancer, discusses important patient factors to consider when deciding between a CAR T-cell therapy vs bispecific antibody in relapsed/refractory multiple myeloma. Different technological approaches are evolving, such as bicistronic CAR T cells, tandem CAR T cells, and CAR T-cell products for 2 different targets administered together or sequentially. Recently, in a pioneering first-in-human phase I . In contrast to CAR T cells, blinatumomab has an in vivo half-life of 2 to 4 hours and requires continuous IV infusion. Freedman AS, Jacobson CA, Mauch P, Aster JC. Dual-specific antibody constructs and CAR T cells are being developed to counteract monotargeting escape. This is in sharp contrast to blinatumomab treatment in which responding patients often recover their neutrophil counts while receiving blinatumomab infusion, resulting into a lower rate of short-term infectious complications.4 After either blinatumomab or CD19 CAR T-cell infusion, long-term B-cell aplasia and hypogammaglobulinemia have been reported, although it is more profound after CAR T-cell therapy. Your doctor will check your blood cell counts regularly during your treatment. More serious side effects include infection, fluid collection in the lungs, around the heart, or in the abdomen (belly), very low blood counts, and very severe skin reactions when out in the sun. We keep striving for a cure. These drugs can also increase your risk of certain serious infections for many months after the drug is stopped. We can also help you find other free or low-cost resources available. CAR T-cell Therapy and Its Side Effects - American Cancer Society For patients who have multiple myeloma and adequate physiologic organ function, and agree to [undergo] transplant, transplant is considered standard. The clinical success of CAR T cell therapy for the treatment of B-ALL and diffuse large B cell lymphoma is due, in part, to targeting the CD19 antigen, an ideal candidate owing to its high . CARs are engineered synthetic receptors that. Yes, we could have a BCMA-directed target, but if we add that with a targeted agent against some specific enzyme deficiency or genetic abnormality, it [will be a valuable] addition to these other mechanisms. There are probably over 30 different companies that are trying to [manufacture] CAR T cells in multiple myeloma. On the other hand, T cell activation by genetically engineered CAR receptor via the TCR/CD3 and costimulatory domains can induce potent immune responses against specific tumor-associated antigens (TAAs). of cycles: 1-2; in-hospital days: r/r setting: 9 d within the first cycle (MRD setting: 3 d), 2 d second cycle; additional costs: pump equipment, possible IgG-replacement therapy for 6-12 mo, Products: > US$350000; no. Once connected, it is drawn into the lymphoma cell where the chemo is released and destroys it. The great advantage of this approach is an increase in the safety profile, as the infusion can be stopped at any time, thereby reversing immune activation and immune-related adverse events. Please enable it to take advantage of the complete set of features! They are tolerated better and their efficacy is better than conventional chemotherapy. [These triplets] are based on different categories of drugs such as PIs, immunomodulatory drugs (IMiDs), and corticosteroids. In the TOWER trial, 267 of 271 patients assigned to receive blinatumomab received the treatment.4 However, allogeneic engineered cell products are in preclinical and early clinical development and, with further development, should enable off-the-shelf allogeneic CAR T cell10 or CAR natural killer cell11 therapy.
