Two companies are neck-and-neck with the FDA submission for CAR T-cell therapy approval. A number of monoclonal antibodies target the CD20 antigen, a protein on the surface of B lymphocytes. Immune system cells normally have substances that act as checkpoints to keep them from attacking other healthy cells in the body. Rituxan was the original brand name for rituximab, but several similar versions (calledbiosimilars) are now available as well, including Ruxience, Truxima, and Riabni. The data strongly support the use of blinatumomab in MRD-positive patients with BCP-ALL. The DREAMM-1 study essentially [evaluated whether] belantamab mafodotin had any activity [in patients with relapsed/refractory multiple myeloma]. 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. The first-generation CAR-T cells only contain one intracellular signal domain CD3. The combination of BiTEs as an adapter strategy for CAR T cells is currently being tested in early clinical trials. The FDA approval of belantamab mafodotin was based on data from the DREAMM-2 trial. The T cells are then multiplied in the lab and given back into the patients blood, where they can seek out the lymphoma cells and launch a precise immune attack against them. doi: 10.1016/S1470-2045(10)70130-3. Selinexor is an [oral] pill given once or twice a week, depending on the schedule. CAR T cells can persist and expand in patients and are typically given as a single transfusion (as in the ZUMA-1 trial). 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. This drug can cause some of the same side effects as other antibodies that target CD20, including infusion reactions (see above). 2018; 41:114-121. Further, CAR T-cell therapy is [a] one-and-done [approach]. Our group is a bit unique because we are not particularly in favor of maintenance therapy. CAR-T- and a side order of IgG, to go?- Immunoglobulin . DREAMM-2 is the phase 2 trial that led to the FDA approval for the drug. Similar to the DREAMM studies, these agents are being combined with many of the standard therapies that we currently use. Possible side effects include local skin reactions, like redness, where the drug is injected, infections, low white blood cell counts, nausea, fatigue, and constipation. 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. The American Cancer Society medical and editorial content team. Monoclonal Antibodies, ADCs, and CAR T Cells Invigorate the - OncLive Neelapu SS, Locke FL, Bartlett NL, et al. Scott AM. Version 3.2018. There will likely be a lot of competing options for BCMA-directed therapy. Available Every Minute of Every Day. Careers. Clearly, challenges in production, manufacturing, and safety should be balanced against response rates. From a hematologic standpoint, it can lower white [blood cell] counts and platelet counts, but that is usually not a major consequence. These drugs can also increase your risk of certain serious infections for many months after the drug is stopped. Cytokines are immune substances that have many different functions in the body. Methods: Chimeric Antigen Receptor (CAR) T-cell therapy involves genetic modification of patient's autologous T-cells to express a CAR specific for a tumor antigen, following by ex vivo cell expansion and re-infusion back to the patient. With CAR T cells, patients get their therapy, get their response, and may not require treatment for an extended period of time. Severe nausea, vomiting, and/or diarrhea. However, the dose of CAR T cells used in these trials varies and also differs among recipients within a single trial. How do you see CAR T-cell therapy impacting the landscape of multiple myeloma? -. Marion Subklewe; BiTEs better than CAR T cells. 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. Practice Guidelines in Oncology: B-cell Lymphomas. Bispecific T cell engagers: an emerging therapy for management of Selinexor has a completely different toxicity profile; gastrointestinal toxicities are mainly seen with this agent. 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. For patients who have multiple myeloma and adequate physiologic organ function, and agree to [undergo] transplant, transplant is considered standard. Weve certainly made major headway, but their OS remains in the 4- to 6-year range, which is much lower than what we see with those patients who do not have adverse cytogenetic features. Chapter 106: Non-Hodgkin Lymphoma. Making Strides Against Breast Cancer Walks, ACS Center for Diversity in Research Training, Targeted Drug Therapy for Non-Hodgkin Lymphoma, Radiation Therapy for Non-Hodgkin Lymphoma, High-Dose Chemotherapy and Stem Cell Transplant for Non-Hodgkin Lymphoma, Palliative and Supportive Care for Non-Hodgkin Lymphoma. This article sets out that case, but personally, I see room in the clinic for both. As a single agent, belantamab mafodotin is currently approved for patients who have been heavily pretreated with 4 or more prior lines of therapywhich is a lot of chemotherapy. Retrieved from https://www.fda.gov/Drugs/InformationOnDrugs/ApprovedDrugs/ucm610670.htm. [The FDA] doesnt specify lines of therapies, so it is an interpretation of what that means. How has the treatment of multiple myeloma evolved? The engineered CAR T . CAR T-cell therapy can cause a serious side effect known as cytokine release syndrome. Serious infections: Some people might get a serious infection while getting this drug. Monoclonal antibodies and chimeric antigen receptor (CAR) T cells in Polatuzumab vedotin (Polivy) is an anti-CD79b antibody attached to a chemotherapy drug (an antibody-drug conjugate). However, looking at grade 3 CRS and ICANS in blinatumomab-treated patients, the event rate was much lower compared with the CAR T trials, with 4.9% for CRS and 9% for ICANS. 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. Your doctor may check your blood for signs of an old hepatitis B infection before you start treatment. David H. Vesole, MD, PhD, discusses the evolution of multiple myeloma treatment, and explained how other BCMA-therapies are poised to impact clinical practice. Lenalidomide can be given with or without rituximab, or along with tafasitamab. We didnt have that option when I started. 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 . Pharmacological immunosuppression, such as using tocilizumab and/or corticosteroids, is necessary to manage these toxicities.13 In contrast, because of its short half-life, blinatumomab treatment can be interrupted or discontinued if necessary, without prolonged effect. Therefore, both platforms rely on T-cell context, and it is unclear to what extent the ex vivo production of CAR T cells can overcome T-cell dysfunction at the start of the process.12, For both platforms, evolving T-cell exhaustion is highly relevant due to the fact that repeated antigen exposure takes place.34 BiTE proteins are given as a continuous infusion with intermittent treatment-free intervals. The mitigation of CRS was achieved through implementing dose steps in addition to prophylactic anti-inflammatory drugs (initially dexamethasone, prospectively tocilizumab). Alemtuzumab (Campath) is an antibody directed at the CD52 antigen. Monoclonal antibodies (mAbs) and chimeric antigen receptor (CAR) T cells are two branches of cancer immunotherapy. Grade 3 CRS and neurologic events were observed in the ZUMA-1 trial in 32% of treated patients.8 In the JULIET trial, grade 3 CRS and neurologic events occurred in 22% and 12% of treated patients, respectively6; in the ELIANA trial, these cases were 46% and 13%, respectively.7 The expansion and persistence of CAR T cells make it difficult to stop CAR T-cell treatments if toxicity is observed. 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. Some people have infusion reactions while getting this drug, which can cause symptoms like chills, flushing, headache, or shortness of breath during the infusion. Treating Cancer with Immunotherapy | Types of Immunotherapy doi: 10.1016/j.chemosphere.2018.06.118. Global cancer statistics 2018: GLOBOCAN estimates of incidence and mortality worldwide for 36 cancers in 185 countries. For data sharing requests, e-mail the corresponding author, Marion Subklewe (marion.subklewe@med.uni-muenchen.de). CRS occurs in almost all patients treated with CAR T-cell therapy; in fact, the presence of CRS is a diagnostic marker that indicates the CAR T-cells are working as intended to kill . -, Thanikachalam K, Khan G. Colorectal cancer and nutrition. Recently, in a pioneering first-in-human phase I . This is quite impressive for a group of patients whose lifespan would be shorter than patients who have not received 4 prior lines of therapy. Right now, we have the option to make this a chronic disease in the same way high blood pressure or diabetes [are chronic diseases]. CAR T-cell therapy is used to treat certain blood cancers. The vast majority of them are using BCMA as the target, but that is not the only target that is available. Patients get CAR T cells on day 1 and they may not need therapy for 1 or 2 years, perhaps longer. Any sequence can be inserted into various portions of the antibody molecule. The CAR T-cell technology continues to improve. As well as personalized individual treatments using BiTEs or CAR T cells, one innovative way this could manifest itself is in the combination of BiTEs as an adapter strategy with universal CAR T cells that might overcome the clinical stings of T-cell dysfunction while maintaining the benefits of BiTE constructs. Mosunetuzumab (Lunsumio) is a type of antibody known as a bispecific T-cell engager (BiTE). This drug is infused into a vein (IV), usually 3 times a week for up to 12 weeks. Then, lysozymes break down the link between the chemotherapy drug and the antibody, which allows the chemotherapy drug to kill the cell [from within]. . We're improving the lives of cancer patients and their families through advocacy, research, and patient support to ensure that everyone has an opportunity to prevent, detect, treat, and survive cancer. The authors declare that they have no competing interests. and with tocilizumab, an anti-IL-6 monoclonal antibody. However, a direct comparison of the response rates is invalid due to the differences in patients treated in each trial. 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. In the ELIANA trial, 75 of 92 enrolled patients received tisa-cel, with a median of 45 days from enrollment to infusion. -, Martin FL, Martinez EZ, Stopper H, Garcia SB, Uyemura SA, Kannen V. Increased exposure to pesticides and colon cancer: Early evidence in Brazil. This drug is infused into a vein (IV), typically about once a week for the first few months, and then once every two weeks. The new monoclonal and bispecific antibodies and CAR-T, besides offering new perspectives in the overall survival and disease-free survival of patients, may also transform the epidemiology of infections in ALL by improving the toxicity of treatments. 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. Ultimately, this is what is going to happen. Chimeric antigen receptor (CAR)-T cell therapy has been revolutionary as it has produced remarkably effective and durable clinical responses 1.
