Efbemalenograstim alfa, sold under the brand name Ryzneuta, is a medication used to decrease the incidence of infection in chemotherapy-induced neutropenia. [1] It is a leukocyte growth factor. [1] It is given by subcutaneous injection. [1]
Efbemalenograstim alfa is an immunostimulant/colony stimulating factor that belongs to the class of hematopoietic growth factors (granulocyte colony stimulating factor; G CSF) which increase the production and differentiation of mature and functionally active neutrophils from bone marrow precursor cells. [3]
It was approved for medical use in China in May 2023, [2] and in the United States in November 2023. [1] [4]
Efbemalenograstim alfa is indicated to decrease the incidence of infection, as manifested by febrile neutropenia, in adults with non-myeloid malignancies receiving myelosuppressive anti-cancer drugs associated with a clinically significant incidence of febrile neutropenia. [5]
In January 2024, the Committee for Medicinal Products for Human Use of the European Medicines Agency adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Ryzneuta, intended to reduce the duration of neutropenia and the incidence of febrile neutropenia due to chemotherapy. [3] The applicant for this medicinal product is Evive Biotechnology Ireland Limited. [3]
Darbepoetin alfa (INN) is a re-engineered form of erythropoietin containing 5 amino acid changes resulting in the creation of 2 new sites for N-linked carbohydrate addition. It has a 3-fold longer serum half-life compared to epoetin alpha and epoetin beta. It stimulates erythropoiesis by the same mechanism as rHuEpo and is used to treat anemia, commonly associated with chronic kidney failure and cancer chemotherapy. Darbepoetin is marketed by Amgen under the trade name Aranesp.
Neutropenia is an abnormally low concentration of neutrophils in the blood. Neutrophils make up the majority of circulating white blood cells and serve as the primary defense against infections by destroying bacteria, bacterial fragments and immunoglobulin-bound viruses in the blood. People with neutropenia are more susceptible to bacterial infections and, without prompt medical attention, the condition may become life-threatening.
Bone marrow suppression also known as myelotoxicity or myelosuppression, is the decrease in production of cells responsible for providing immunity (leukocytes), carrying oxygen (erythrocytes), and/or those responsible for normal blood clotting (thrombocytes). Bone marrow suppression is a serious side effect of chemotherapy and certain drugs affecting the immune system such as azathioprine. The risk is especially high in cytotoxic chemotherapy for leukemia.
Filgrastim, sold under the brand name Neupogen among others, is a medication used to treat low neutrophil count. Low neutrophil counts may occur with HIV/AIDS, following chemotherapy or radiation poisoning, or be of an unknown cause. It may also be used to increase white blood cells for gathering during leukapheresis. It is given either by injection into a vein or under the skin. Filgrastim is a leukocyte growth factor.
Bevacizumab, sold under the brand name Avastin among others, is a monoclonal antibody medication used to treat a number of types of cancers and a specific eye disease. For cancer, it is given by slow injection into a vein (intravenous) and used for colon cancer, lung cancer, ovarian cancer, glioblastoma, and renal-cell carcinoma. In many of these diseases it is used as a first-line therapy. For age-related macular degeneration it is given by injection into the eye (intravitreal).
Pegfilgrastim, sold under the brand name Neulasta among others, is a PEGylated form of the recombinant human granulocyte colony-stimulating factor (GCSF) analog filgrastim. It serves to stimulate the production of white blood cells (neutrophils). Pegfilgrastim was developed by Amgen.
Epoetin alfa is a human erythropoietin produced in cell culture using recombinant DNA technology. Authorised by the European Medicines Agency on 28 August 2007, it stimulates erythropoiesis and is used to treat anemia, commonly associated with chronic kidney failure and cancer chemotherapy.
Tremelimumab, sold under the brand name Imjudo, is a fully human monoclonal antibody used for the treatment of hepatocellular carcinoma. Tremelimumab is designed to attach to and block CTLA-4, a protein that controls the activity of T cells, which are part of the immune system.
Spectrum Pharmaceuticals is an American biopharmaceutical company located in Boston, MA. It develops and markets drugs for treatments in hematology and oncology.
Cabazitaxel, sold under the brand name Jevtana, is a semi-synthetic derivative of a natural taxoid. It is a microtubule inhibitor, and the fourth taxane to be approved as a cancer therapy.
Atezolizumab, sold under the brand name Tecentriq, is a monoclonal antibody medication used to treat urothelial carcinoma, non-small cell lung cancer (NSCLC), small cell lung cancer (SCLC), hepatocellular carcinoma and alveolar soft part sarcoma, but discontinued for use in triple-negative breast cancer (TNBC). It is a fully humanized, engineered monoclonal antibody of IgG1 isotype against the protein programmed cell death-ligand 1 (PD-L1).
Sacituzumab govitecan, sold under the brand name Trodelvy, is a Trop-2-directed antibody and topoisomerase inhibitor drug conjugate used for the treatment of metastatic triple-negative breast cancer and metastatic urothelial cancer.
Eflapegrastim, sold under the brand name Rolvedon among others, is a long-acting G-CSF analog developed by Hanmi Pharmaceutical and licensed to Spectrum Pharmaceuticals. Eflapegrastim is a leukocyte growth factor. It is used to reduce the risk of febrile neutropenia in people with non-myeloid malignancies receiving myelosuppressive anti-cancer agents.
Trilaciclib, sold under the brand name Cosela, is a medication used to reduce the frequency of chemotherapy-induced bone marrow suppression.
Trastuzumab deruxtecan, sold under the brand name Enhertu, is an antibody-drug conjugate consisting of the humanized monoclonal antibody trastuzumab (Herceptin) covalently linked to the topoisomerase I inhibitor deruxtecan. It is licensed for the treatment of breast cancer or gastric or gastroesophageal adenocarcinoma. Trastuzumab binds to and blocks signaling through epidermal growth factor receptor 2 (HER2/neu) on cancers that rely on it for growth. Additionally, once bound to HER2 receptors, the antibody is internalized by the cell, carrying the bound deruxtecan along with it, where it interferes with the cell's ability to make DNA structural changes and replicate its DNA during cell division, leading to DNA damage when the cell attempts to replicate itself, destroying the cell.
Pertuzumab/trastuzumab/hyaluronidase, sold under the brand name Phesgo, is a fixed-dose combination medication to treat adults with HER2-positive breast cancer that has spread to other parts of the body, and for treatment of adults with early HER2-positive breast cancer. It contains pertuzumab, trastuzumab, and hyaluronidase–zzxf. It is injected under the skin via subcutaneous injection in the thigh. In the European Union, Phesgo contains the active ingredients pertuzumab and trastuzumab along with the enzyme vorhyaluronidase alfa.
Lipegfilgrastim, sold under the brand name Lonquex, is a medication used to reduce the duration of neutropenia and the incidence of febrile neutropenia in adults. It is given by injection under the skin in the abdomen, upper arm or thigh.
Trastuzumab/hyaluronidase, sold under the brand name Herceptin SC among others, is a fixed-dose combination medication for the treatment of HER2-overexpressing breast cancer in adults. It is a combination of trastuzumab and hyaluronidase.
Amivantamab, sold under the brand name Rybrevant, is a bispecific monoclonal antibody used to treat non-small cell lung cancer. Amivantamab is a bispecific epidermal growth factor (EGF) receptor-directed and mesenchymal–epithelial transition (MET) receptor-directed antibody. It is the first treatment for adults with non-small cell lung cancer whose tumors have specific types of genetic mutations: epidermal growth factor receptor (EGFR) exon 20 insertion mutations.
Efgartigimod alfa, sold under the brand name Vyvgart, is a medication used to treat myasthenia gravis. Efgartigimod alfa is a neonatal Fc receptor blocker and is a new class of medication. It is an antibody fragment that binds to the neonatal Fc receptor (FcRn), preventing FcRn from recycling immunoglobulin G (IgG) back into the blood. The medication causes a reduction in overall levels of IgG, including the abnormal acetylcholine receptor (AChR) antibodies that are present in myasthenia gravis. It is also available coformulated with hyaluronidase.
