Here we discussed the advances . In chimeric mAbs, the variable regions of a mice Ab is fused with the constant regions of a human Ab. To learn more about how drugs that work on the immune system are used to treat cancer, see Cancer Immunotherapy. Unable to load your collection due to an error, Unable to load your delegates due to an error, The structure of different types of mAbs. Other diseases have ADCs as well, but [belantamab mafodotin] is the first approved in multiple myeloma. These include: These drugs are given into a vein (IV), often over several hours. Although they are not currently the standard of care, I anticipate within the next 5 years that they will become the standard of care potentially up front, as well as in the relapsed/refractory settings for patients with multiple myeloma. [Historically], we would see, at most, a 20% likelihood of achieving a complete remission (CR). Iran J Immunol. When we combine belantamab mafodotin with other active agents with different mechanisms of action, we can see superior response rates and remission durations. 5th ed. Abeloffs Clinical Oncology. Then we come back with salvage therapy, usually with triplet regimens, of which there are a number approved by the FDA for patients who have had 1 to 3 prior lines of therapy. We can also help you find other free or low-cost resources available. And there are many more in development. 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. This brings the two together, which helps the immune system attack the lymphoma cells. Brentuximab can be used to treat some types of T-cell lymphoma, either as the first treatment (typically along with chemo) or if the lymphoma if it has come back after other treatments. In children and young adults with BCP-ALL with 3 months of follow-up, tisa-cel achieved a CR rate of 81%. There are probably over 30 different companies that are trying to [manufacture] CAR T cells in multiple myeloma. Rituxan was the original brand name for rituximab, but several similar versions (calledbiosimilars) are now available as well, including Ruxience, Truxima, and Riabni. -, Veisi Malekshahi Z, Hashemi Goradel N, Shakouri Khomartash M, Maleksabet A, Kadkhodazadeh M, Kardar GA, et al. They all can cause reactions during the infusion (while the drug is being given) or several hours afterward. Correspondence: Marion Subklewe, Hematology/Oncology, LMUKlinikum der Universitt Mnchen, Marchioninistr 15, 81377 Munich, Germany; e-mail: marion.subklewe@med.uni-muenchen.de. Nutrients. Common side effects can include nerve damage (neuropathy), low blood counts, fatigue, fever, nausea and vomiting, infections, diarrhea, and cough. Vesole: All patients with multiple myeloma are BCMA positive. Monoclonal antibodies are made in a laboratory to boost the body's natural antibodies or act as antibodies themselves. In: DeVita VT, Lawrence TS, Rosenberg SA, eds. These other agents have different toxicities profiles and different response rates. Effects of KRAS, BRAF, NRAS, and PIK3CA mutations on the efficacy of cetuximab plus chemotherapy in chemotherapy-refractory metastatic colorectal cancer: a retrospective consortium analysis. CAR T-cell therapy can cause toxicities, but in contrast to lymphoma and leukemia, most of them are minor in multiple myeloma. It can also cause some other, more serious side effects, including: Cytokine release syndrome (CRS): This side effect can occur when T cells in the body release chemicals (cytokines) that ramp up the immune system. Some people have infusion reactions while getting this drug, which can cause symptoms like chills, flushing, headache, or shortness of breath during the infusion. CAR T cells can persist and expand in patients and are typically given as a single transfusion (as in the ZUMA-1 trial). Dual-specific antibody constructs and CAR T cells are being developed to counteract monotargeting escape. Right now, CAR T cells are predominantly made using a patients own cells, which takes 2 to 4 weeks to generate, genetically modified, and engineered before being returned to the patient. The use of adapter CAR T cells is aimed at combining the benefits of BiTE molecules with the power of ex vivoactivated CAR T cells. The authors declare that they have no competing interests. [Both] are BCMA-directed therapies. Thalidomide can also cause drowsiness, fatigue, and severe constipation. The strategy of combining targeting tumor antigens has also been applied to chimeric antigen receptor (CAR) T cell therapy and is a promising immunotherapy for several malignancies, such as . Youll likely get medicines before treatment to help lower this risk, but its important to tell your healthcare provider right away if you have any of these symptoms. Harnessing the power of immune cells, especially T cells, to enhance anti-tumor activities has become a promising strategy in clinical management of hematologic malignancies. Your doctor will check your blood cell counts regularly during your treatment. 2019;16:235245. Although quadruplets are quite effective up front, they are not FDA approved at this point in time. [Moreover,] there is at most a 10-day window in which these abnormalities occur, after which patients are essentially home free for the duration of time the cells are effective. Bispecific antibodies are a little bit further away from receiving regulatory approval, but are also BCMA-directed therapies. Currently, triplet therapy seems to be the standard of care, but what is evolving is whether we should give quadruplet regimens with monoclonal antibodies in addition to those same 3 classes of drugs I mentioned. These receptors can attach to proteins on the surface of lymphoma cells. [Moreover,] there is at most a 10-day window in which these. OncLive: What makes BCMA a logical target in multiple myeloma? BCMA stands for B-cell maturation agent, and all myeloma cells have some expression of BCMA on their cell surface. In addition, antigen-targeted approaches of monoclonal antibodies, CAR-T cell therapy, and TCR-based therapy have shown varied successes against . Clearly, intertrial comparisons are problematic per se and are further complicated by differences in toxicity grading systems,14 trial design, inclusion and exclusion criteria (including disease entities [TOWER and JULIET (r/r ALL vs ZUMA-1 and ELIANA (r/r diffuse large B-cell lymphoma [DLBCL])]), and patient cohorts (eg, average age within the JULIET trial was 11 years of age, whereas the other trials were conducted on adults). Mosunetuzumab can be used to treat follicular lymphoma that has returned or that is no longer responding after treatment with at least 2 other types of drugs. Given this risk, the company that makes these drugs puts restrictions on access to them to prevent women who are or might become pregnant from being exposed to them. Careers. Targeting different tumor antigens, either simultaneously or sequentially, might be a strategy for bypassing this path of resistance. The median time from leukapheresis to delivery was 17 days, and 101 of these patients received treatment.8 The long turnaround times are clinically relevant, as patients carry a high intrinsic risk for disease progression during the production process. Although this is the first approved [BCMA-directed] drug, there are a lot of other therapies directed against BCMA that have different toxicity profiles than belantamab mafodotin. We are not going to control multiple myeloma with single agents. Therefore, since 2003, [multiple drugs have been] approved for the treatment of myeloma. 2021;11(4 . In this regard, BiTEs compare favorably to CAR T cells once the costs of production, logistics, treatment, days of hospitalization, and short- and long-term adverse events have been considered (Table 1).37 Importantly, the long-term response rate to BiTEs and CAR T-cell therapy is critical to estimate the cost-effectiveness of these novel treatment platforms. 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. Primary Analysis of Juliet: A Global, Pivotal, Phase 2 Trial of CTL019 in Adult Patients with Relapsed or Refractory Diffuse Large B-Cell Lymphoma. How does this agent compare with others in the space? The structure of different types of mAbs. Brexucabtagene autoleucel (Tecartus, also known as brexu-cel) is approved to treat adults with mantle cell lymphoma that has come back or is no longer responding to other treatments. This drug can be used with bendamustine and rituximab to treat DLBCL, if the lymphoma has come back after receiving two other treatments. 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. Drugs such as thalidomide (Thalomid) and lenalidomide (Revlimid) are thought to work against certain cancers by affecting parts of the immune system, although exactly how they work isnt clear. An example is blinatumomab (Blincyto), which binds to both CD19, a protein found on the surface of leukemia cells, and CD3, a protein on the surface of T cells. 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. That is, in addition to targets that are widely expressed on the myeloma cells themselves such as BCMA. Axicabtagene ciloleucel (Yescarta, also known as axi-cel) is a type of CAR T-cell therapy approved to treat people with: Tisagenlecleucel (Kymriah, also known as tisa-cel) is approved to treat people with diffuse large B-cell lymphoma, high grade B-cell lymphoma, and diffuse large B-cell lymphoma arising from follicular lymphoma, as well as follicular lymphoma that hasnt responded to or has come back after other therapies,after trying at least two other kinds of treatment. [The FDA] doesnt specify lines of therapies, so it is an interpretation of what that means. Where does belantamab mafodotin fit into the paradigm? This drug is infused into a vein (IV), typically every 3 weeks. doi: 10.3322/caac.21492. Roschewski MJ, Wilson WH. CAR T cells are patients own lymphocytes that are genetically modified to improve their activity in targeting their own myeloma cells. Cytokine release syndrome (CRS): As CAR T cells multiply, they can release large amounts of chemicals called cytokines into the blood, which can ramp up the immune system. However, most disease relapses do not feature loss of the target antigen but present with other immune-related escape mechanisms, including the upregulation of inhibitory checkpoint molecules, most commonly PD-L1.28 To reverse this adaptive immune escape mechanism, several antiPD-1 or antiPD-L1 monoclonal antibodies are currently used in combination with blinatumomab and CAR T cells. The blood of the patient is collected and, Five generations of CAR-T cells. Unauthorized use of these marks is strictly prohibited. of treatment applications: 1; additional costs: logistics, leukapheresis, lymphodepleting chemotherapy, average 10-d in-hospital stay (outpatient to long-term stay, including ICU), possible IgG-replacement therapy for months to years, High flexibility to combine different BiTE constructs given in parallel or sequentially, dual-specific BiTE constructs in clinical trials, individualized combinatorial approach of targeting BiTE construct and immunomodulatory construct feasible, Various dual-targeting CAR T-cell constructs in clinical trials; possibility to apply simultaneously vs sequentially, Potentially, reversal through treatment-free intervals (induction: 4 wk on, 2 wk off; maintenance: 4 wk on, 8 wk off), Preclinical work: drug-induced cessation of CAR receptor signaling to prevent or reverse exhaustion; genetically engineered CAR T cells to counteract exhaustion. Our group is a bit unique because we are not particularly in favor of maintenance therapy. Leaked Data Show Cilta-cel Delivers 74% Reduction in Risk of Progression in Early Relapsed/Refractory Myeloma, Jakubowiak Highlights PFS Benefit Seen With KRd Maintenance in Newly Diagnosed Multiple Myeloma, FDA Accepts sBLA for Ide-cel in Triple-class Exposed Relapsed/Refractory Myeloma, FDA Approval Insights: Pirtobrutinib in MCL, Retrospective Study Provides Real-World Insight on Ide-cel in R/R Multiple Myeloma With Renal Impairment, FDA Places Partial Clinical Hold on Phase 1 Trial of MT-0169 in R/R Myeloma or Non-Hodgkin Lymphoma, Dr Daneschmand on Data From SunRISe-1 With TAR-200 and Cetrelimab in BCG-Unresponsive NMIBC, Dr Saad on PSA Response and Time to PSA Progression With Abiraterone Acetate and Olaparib in mCRPC, Pembrolizumab Monotherapy Demonstrates Clinical Efficacy in High-risk NMIBC, TAR-200 Produces High CR Rates, Tolerability in BCG-unresponsive NMIBC, OncLive National Fellows Forum: Lung Cancer 2023, Join us in Chicago for Giants of Cancer Care, Belantamab Mafodotin in Relapsed/Refractory Myeloma Requires Multidisciplinary Effort, Monoclonal Antibodies, ADCs, and CAR T Cells Invigorate the Myeloma Paradigm, From the Ophthalmologists Eye: Managing Ocular Toxicities With Belantamab Mafodotin in Myeloma, BCMA-Targeted Approaches Revolutionize Relapsed/Refractory Myeloma Treatment, Novel Combos With Belantamab Mafodotin May Move the Needle in Myeloma, | Join us in Chicago for Giants of Cancer Care. On the other hand, graft-versus-host disease and rejection of CAR T cells might counteract the benefit of allogeneic cell products.12, Comparison of blinatumomab vs CD19 CAR T cells. Bispecific antibody constructs are available off the shelf, whereas CAR T cells have to be engineered for each individual patient. 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. Ask your doctor what you can expect. AE, adverse event; ICU, intensive care unit; IgG, immunoglobulin G; Ph, Philadelphia chromosome; PMBCL, primary mediastinal B-cell lymphoma; SOC, standard of care; Tx, treatment; WBCs, white blood cells. most of these therapies can be given with the prolongation of life, without negatively impacting QOL a great deal.. Version 3.2018. Interestingly, a common denominator of response was identified across trials: patients treated in the setting of MRD had a significantly better response and long-term survival compared with patients with a high tumor load.5,20 A comparison of clinical trials revealed that the recurrence-free survival in patients (n = 255) treated with blinatumomab in the MRD setting (MRD cutoff: 103) was 35.2 months vs 7.3 months in the r/r setting (n = 271).4,21 For CAR T cells, the number of reported patients treated in the MRD setting is much lower, and no MRD-focused trials have yet been reported. Although [these agents] are not completely devoid of other toxicities, they focus predominantly on myeloma cells. Biologically, the monoclonal antibody attaches to the myeloma cell, which is endocytosed into the cell. A third very common toxicity of CAR T-cell therapy consists of prolonged and severe cytopenia that can predispose for severe infectious complications.15 CAR T-cellassociated hematotoxicity is related to mandatory lymphodepleting chemotherapy prior to CAR T-cell infusion and immunomodulation through CAR T cells. Nonetheless, the use of such new drugs to treat solid tumors is not . Besides common therapeutic approaches, such as surgery, chemotherapy, and radiotherapy, novel therapeutic approaches, including immunotherapy, have been an advent in CRC treatment. For patients who respond [to belantamab mafodotin], the duration of response exceeds 11 months. In contrast to CAR T cells, blinatumomab has an in vivo half-life of 2 to 4 hours and requires continuous IV infusion. There will likely be a lot of competing options for BCMA-directed therapy. -, Thanikachalam K, Khan G. Colorectal cancer and nutrition. This opens up a wide avenue of patients with multiple myeloma who may have exhausted all other potential treatments. Both of these approaches have beneficial anti-tumor effects on CRC. B cells are a type of white blood cell. It is a little bit confusing because, in theory, we could use [belantamab mafodotin] in the second- or third-line settings. antibodies targeting immune checkpoints, bispecific antibodies, and chimeric antigen receptor [CAR]-T cells), is raising questions on their potential immunogenicity and effects on treatment. BiTEs provide the advantage of flexibility of targeting multiple antigens simultaneously and sequentially and can be used in combination with chemotherapy, small molecules, and immunomodulatory drugs, such as checkpoint inhibitors. The American Cancer Society offers programs and services to help you during and after cancer treatment. How has the treatment of multiple myeloma evolved? Monoclonal antibodies. This requires (1) a defined number of leukocytes and lymphocytes as a prerequisite for successful leukapheresis, depending on the CAR T-cell product and disease entity; (2) the isolation of T cells from the leukapheresis product; (3) transduction of these T cells with the vector that expresses the CAR; (4) expanding the transduced T cells to a sufficient number; (5) conditioning the patient; and (6) transfusing the patient with the CAR T cells. Chimeric antigen receptor (CAR)-T cell therapy has been revolutionary as it has produced remarkably effective and durable clinical responses 1. The increasing use of multiple immunomodulatory (IMD) agents for cancer therapies (e.g. Tax ID Number: 13-1788491. We are going to have a whole list of additional options with these BCMA-directed therapies in the very near future. We are not sure if they will be covered by third-party carriers. Other monoclonal antibodies bring T cells close to cancer cells, helping the immune cells kill the cancer cells. Because CAR T-cell therapy can have serious side effects, it is only given in medical centers that have special training with this treatment. We keep striving for a cure. Bookshelf Tisa-cel achieved a 52% ORR, including a 40% CR rate, in adult patients with r/r DLBCL in the JULIET trial. 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. Here the authors present an IgE antibody targeting the melanoma-associated antigen, chondroitin sulphate proteoglycan 4 . Belantamab mafodotin-blmf (Blenrep) received regulatory approval in August 2020. BiTE-based approaches are particularly promising against early-stage disease with low tumor burden (eg, in the MRD setting of BCP-ALL) and a still-functional T-cell compartment. We can control a patients disease for an unbelievably extended period of time. Severe nausea, vomiting, and/or diarrhea. Once connected, it is drawn into the lymphoma cell where the chemo is released and destroys it. Research. The second-generation CARs consist of a co-stimulatory domain, including 4-1BB (CD137) or CD28, whereas the third-generation ones have two co-stimulatory domains. How has the DREAMM series evolved since the approval? Our team is made up of doctors andoncology certified nurses with deep knowledge of cancer care as well as journalists, editors, and translators with extensive experience in medical writing. See this image and copyright information in PMC, LGD19H160001/zhejiang provincial science and technology projects, 81772537/National Natural Science Foundation of China, 81374014/National Natural Science Foundation of China, 81903597/National Natural Science Foundation of China, LQ16H310003/Zhejiang Provincial Natural Science Foundation, Bray F, Ferlay J, Soerjomataram I, Siegel RL, Torre LA, Jemal A. CAR T-cell therapy is used to treat certain blood cancers. We couldnt do what we do without our volunteers and donors. Finally, both treatment platforms are associated with high financial toxicity. To me, this is the most exciting area because it is a one-and-done [approach] versus continued therapy. In the ELIANA trial, 75 of 92 enrolled patients received tisa-cel, with a median of 45 days from enrollment to infusion. Antigenized antibodies Antigenization is an investigational approach in which an mAb can be engineered to deliver an antigen (eg, as a vaccine). We would give a triplet regimen, followed by transplant. The time sequence of the reversibility depends on how severe [the toxicity] is. The CAR T-cell technology continues to improve. In the MRD setting, blinatumomab is the only drug approved for the treatment of BCP-ALL, demonstrating the importance of BiTEs in oncology. Moreover, it is expensive and time consuming. Man-made versions, called monoclonal antibodies, can be designed to attack a specific target, such as a substance on the surface of lymphocytes (the cells in which lymphomas start). Rare but serious side effects can include strokes, as well as tears in the blood vessels in the head and neck. For reprint requests, please see our Content Usage Policy. Clinical trials related to TCR-T cell therapy and monoclonal antibodies designed for overcoming immunosuppression, and recent advances made in understanding how TCRs are additionally examined. Accessed at https://www.nccn.org/professionals/physician_gls/pdf/cll.pdf on May 2, 2018. Polatuzumab vedotin (Polivy) is an anti-CD79b antibody attached to a chemotherapy drug (an antibody-drug conjugate). Looking ahead, we need predictive biomarkers to stratify patients to the treatment option with the highest likelihood of cure and mitigate clinical and financial toxicity. Colorectal cancer (CRC) is the third most common cancer and the second leading cause of cancer deaths worldwide. Weve invested more than $5 billion in cancer research since 1946, all to find more and better treatments, uncover factors that may cause cancer, and improve cancer patients quality of life. A study comparing JNJ-68284528, a CAR-T therapy directed against B-cell maturation antigen (BCMA), versus pomalidomide, bortezomib and dexamethasone (PVd) or daratumumab, pomalidomide and . Tisa-cel can also be used on a pediatric population and is indicated for patients <26 years with r/r B-cell precursor acute lymphoblastic leukemia (BCP-ALL).3 Currently, the only BiTE with FDA and EMA approval is blinatumomab, which redirects CD3+ T cells to CD19+ leukemic blasts. In this review, we outline the mechanisms of action (MOA) of approved, antibody-based IMD agents, potentially related . I imagine that in the future, patients are going to get 4 or 5 different drugs, some specific to enzyme pathways, others specific to their individual DNA sequencing. It can also cause very low white blood cell counts, which increases the risk for serious infections. They are tolerated better and their efficacy is better than conventional chemotherapy. Marion Subklewe; BiTEs better than CAR T cells. National Comprehensive Cancer Network (NCCN). Pembrolizumab can be used to treat primary mediastinal large B-cell lymphoma (PMBCL) that has not responded to or has come back after other therapies. DREAMM-2 is the phase 2 trial that led to the FDA approval for the drug. Mosunetuzumab (Lunsumio) is a type of antibody known as a bispecific T-cell engager (BiTE). An official website of the United States government. Other side effects can include feeling tired, rash, fever, and headache. It is approved for the treatment of r/r BCP-ALL, as well as BCP-ALL with minimal residual disease (MRD).4,5, Several aspects favor the application of bispecific T-cellrecruiting antibody constructs compared with the application of CAR T cells (Table 1). We need combination therapies that have different mechanisms of action. A number of monoclonal antibodies target the CD20 antigen, a protein on the surface of B lymphocytes. What challenges remain with regard to treatment in multiple myeloma? Global cancer statistics 2018: GLOBOCAN estimates of incidence and mortality worldwide for 36 cancers in 185 countries. This is done by replacing part of the antibody polypeptide with a fragment of a microbial antigen. Alemtuzumab (Campath) is an antibody directed at the CD52 antigen. Accessibility National Comprehensive Cancer Network (NCCN). Chimeric antigen receptor (CAR) T cells; Colorectal cancer; Immunotherapy; Monoclonal antibody. Furthermore, T-cell subset composition and function determine the response to BiTE treatment.32,33 However, in the case of CAR T cells, T-cell composition and function at time of leukapheresis also influence CAR T function and are further modulated through patient- and disease-related parameters after transfusion. Dexamethasone was used in the TOWER trial prophylactically to prevent CRS and neurologic events; thus, blinatumomabs safety in this regard cannot be compared with tisa-cel or axi-cel. This drug is given as an IV infusion, typically once a week for the first 3 weeks, then once every 3 weeks. The DREAMM-1 study essentially [evaluated whether] belantamab mafodotin had any activity [in patients with relapsed/refractory multiple myeloma]. Nervous system problems: This drug might affect the nervous system, which could lead to symptoms such as headaches, numbness or tingling in the hands or feet, feeling dizzy or confused, trouble speaking or understanding things, abnormal sleep patterns, tremors, or seizures. The future is going to have personalized medicine. Accordingly, blinatumomab is the preferred treatment of choice in this situation with high response rates (88/113 patients with MRD conversion) and a favorable safety profile. Emerging data indicate that [quadruplets] are even more efficacious without a significant increase in toxicity. Selinexor (Xpovio) is another drug that was recently approved for patients who have had 4 prior lines of therapy. -, De Roock W, Claes B, Bernasconi D, De Schutter J, Biesmans B, Fountzilas G, et al. Initial expansion of infused CAR T cells In the vast majority of patients, this is very minor and presents as blurred vision or dry, scratchy eyes. However, for reasons that we do not know, [belantamab mafodotin] can cause problems with the eye, [namely] keratopathy.
