Elranatamab, sold under the brand name Elrexfio, is a medication used for the treatment of multiple myeloma. [6] [10] Elranatamab is a bispecific B-cell maturation antigen (BCMA)-directed CD3 T-cell engager. [6] [10] [11] [12] Elranatamab is given by subcutaneous injection. [6] [10]
The most common side effects include cytokine release syndrome, fatigue, injection site reaction, diarrhea, upper respiratory tract infection, musculoskeletal pain, pneumonia, decreased appetite, rash, cough, nausea, and pyrexia (fever). [10]
Elranatamab was approved for medical use in the United States in August 2023, [6] [10] [13] [14] in the European Union in December 2023, [9] and in Canada in December 2023. [3]
Elranatamab is indicated for the treatment of adults with relapsed or refractory multiple myeloma who have received at least four prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody. [6] [10]
The most common adverse reactions include cytokine release syndrome, fatigue, injection site reaction, diarrhea, upper respiratory tract infection, musculoskeletal pain, pneumonia, decreased appetite, rash, cough, nausea, and pyrexia. [10]
The US Food and Drug Administration (FDA) prescribing information for elranatamab has a boxed warning for life-threatening or fatal cytokine release syndrome and neurologic toxicity, including immune effector cell-associated neurotoxicity. [10]
The safety and effectiveness of elranatamab was evaluated in MagnetisMM-3 (NCT04649359), an open-label, single-arm, multi-center study that included participants with relapsed/refractory multiple myeloma who are refractory to at least one proteasome inhibitor, one immunomodulatory drug, and one anti-CD38 antibody. [10] Overall, the study consisted of 97 participants naïve to prior BCMA-directed therapy and who had previously received at least four prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody. [10]
The FDA granted the application for elranatamab priority review, breakthrough therapy, and orphan drug designations; [10] and granted approval of Elrexfio to Pfizer Inc. [10]
In October 2023, the Committee for Medicinal Products for Human Use of the European Medicines Agency adopted a positive opinion, recommending the granting of a conditional marketing authorization for the medicinal product Elrexfio, intended for the treatment of multiple myeloma. [8] The applicant for this medicinal product is Pfizer Europe MA EEIG. [8]
In 2023, elranatamab was approved for medical use in the United States, [6] [10] in the European Union, [8] [9] and in Canada. [3]
Elranatamab is the international nonproprietary name. [15]
Elranatamab is sold under the brand name Elrexfio. [2] [6] [9]
Multiple myeloma (MM), also known as plasma cell myeloma and simply myeloma, is a cancer of plasma cells, a type of white blood cell that normally produces antibodies. Often, no symptoms are noticed initially. As it progresses, bone pain, anemia, renal insufficiency, and infections may occur. Complications may include hypercalcemia and amyloidosis.
B-cell maturation antigen, also known as tumor necrosis factor receptor superfamily member 17 (TNFRSF17), is a protein that in humans is encoded by the TNFRSF17 gene.
Bi-specific T-cell engagers (BiTEs) are a class of artificial bispecific monoclonal antibodies that are investigated for use as anti-cancer drugs. They direct a host's immune system, more specifically the T cells' cytotoxic activity, against cancer cells. BiTE is a registered trademark of Micromet AG.
Carfilzomib, sold under the brand name Kyprolis, is an anti-cancer medication acting as a selective proteasome inhibitor. Chemically, it is a tetrapeptide epoxyketone and an analog of epoxomicin. It was developed by Onyx Pharmaceuticals.
Daratumumab, sold under the brand name Darzalex among others, is an anti-cancer monoclonal antibody medication. It binds to CD38, which is overexpressed in multiple myeloma cells. Daratumumab was originally developed by Genmab, but it is now being jointly developed by Genmab along with the Johnson & Johnson subsidiary Janssen Biotech, which acquired worldwide commercialization rights to the drug from Genmab.
Isatuximab, sold under the brand name Sarclisa, is a monoclonal antibody (mAb) medication for the treatment of multiple myeloma.
Ixazomib is a drug for the treatment of multiple myeloma, a type of white blood cell cancer, in combination with other drugs. It is taken by mouth in the form of capsules.
Melphalan flufenamide, sold under the brand names Pepaxto and Pepaxti, is an anticancer medication used to treat multiple myeloma.
Selinexor sold under the brand name Xpovio among others, is a selective inhibitor of nuclear export used as an anti-cancer medication. It works by blocking the action of exportin 1 and thus blocking the transport of several proteins involved in cancer-cell growth from the cell nucleus to the cytoplasm, which ultimately arrests the cell cycle and leads to apoptosis. It is the first drug with this mechanism of action.
Daratumumab/hyaluronidase, sold under the brand name Darzalex Faspro, is a fixed-dose combination medication for the treatment of adults with newly diagnosed or relapsed/refractory multiple myeloma. It is a combination of daratumumab and hyaluronidase. It is administered via subcutaneous injection.
Brexucabtagene autoleucel, sold under the brand name Tecartus, is a cell-based gene therapy medication for the treatment of mantle cell lymphoma (MCL) and acute lymphoblastic leukemia (ALL).
Belantamab mafodotin, sold under the brand name Blenrep, is a monoclonal antibody for the treatment of relapsed and refractory multiple myeloma.
Idecabtagene vicleucel, sold under the brand name Abecma, is a cell-based gene therapy to treat multiple myeloma.
Ciltacabtagene autoleucel, sold under the brand name Carvykti, is an anti-cancer medication used to treat multiple myeloma. Ciltacabtagene autoleucel is a BCMA -directed genetically modified autologous chimeric antigen receptor (CAR) T-cell therapy. Each dose is customized using the recipient's own T-cells, which are collected and genetically modified, and infused back into the recipient.
Mosunetuzumab, sold under the brand name Lunsumio, is a monoclonal antibody used for the treatment of follicular lymphoma. It bispecifically binds CD20 and CD3 to engage T-cells. It was developed by Genentech.
Teclistamab, sold under the brand name Tecvayli, is a human bispecific monoclonal antibody used for the treatment of relapsed and refractory multiple myeloma. It is a bispecific antibody that targets the CD3 receptor expressed on the surface of T-cells and B-cell maturation antigen (BCMA), which is expressed on the surface of malignant multiple myeloma B-lineage cells.
Talquetamab, sold under the brand name Talvey, is a humanized monoclonal antibody used for the treatment of multiple myeloma. It is a bispecific GPRC5D-directed CD3 T-cell engager. Talquetamab is a bispecific antibody against two targets: human CD3, a T-cell surface antigen, and human G-protein coupled receptor family C group 5 member D (GPRC5D), a tumor-associated antigen with potential antineoplastic activity. Talquetamab binds both targets, drawing the T cells close to the tumor cells, causing a cytotoxic T-lymphocyte response. It is being developed by Janssen Pharmaceuticals.
Glofitamab, sold under the brand name Columvi, is a bispecific monoclonal antibody used for the treatment of large B-cell lymphoma. It is a bispecific CD20-directed CD3 T-cell engager developed by Roche.
