Adult T-cell leukemia/lymphoma is a rare cancer of the immune system's T-cells caused by human T cell leukemia/lymphotropic virus type 1 (HTLV-1). All ATL cells contain integrated HTLV-1 provirus further supporting that causal role of the virus in the cause of the neoplasm. A small amount of HTLV-1 individuals progress to develop ATL with a long latency period between infection and ATL development. ATL is categorized into 4 subtypes: acute, smoldering, lymphoma-type, chronic. Acute and Lymphoma-type are known to particularity be aggressive with poorer prognosis.
Tipifarnib is a farnesyltransferase inhibitor. Farnesyltransferase inhibitors block the activity of the farnesyltransferase enzyme by inhibiting prenylation of the CAAX tail motif, which ultimately prevents Ras from binding to the membrane, rendering it inactive.
Antifolates are a class of antimetabolite medications that antagonise (that is, block) the actions of folic acid (vitamin B9). Folic acid's primary function in the body is as a cofactor to various methyltransferases involved in serine, methionine, thymidine and purine biosynthesis. Consequently, antifolates inhibit cell division, DNA/RNA synthesis and repair and protein synthesis. Some such as proguanil, pyrimethamine and trimethoprim selectively inhibit folate's actions in microbial organisms such as bacteria, protozoa and fungi. The majority of antifolates work by inhibiting dihydrofolate reductase (DHFR).
Belinostat is a histone deacetylase inhibitor drug developed by TopoTarget for the treatment of hematological malignancies and solid tumors.
Subcutaneous T-cell lymphoma is a cutaneous condition that most commonly presents in young adults, and is characterized by subcutaneous nodules. Common symptoms include fever, fatigue, and pancytopenia.
Southern Research is a not-for-profit US 501(c)(3) research organization that conducts basic and applied research for commercial and non-commercial organizations across four divisions: Drug Development, Drug Discovery, Energy & Environment, and Engineering.
Peripheral T-cell lymphoma not otherwise specified (PTCL-NOS), is a subtype of peripheral T-cell lymphoma. Peripheral T-cell lymphoma (PTCL) is defined as a diverse group of aggressive lymphomas that develop from mature-stage white blood cells called T-cells and natural killer cells. PTCL is a type of non-Hodgkin's lymphoma (NHL). PTCL specifically affects T-cells rather than B-cells, and results when T-cells develop and grow abnormally.
Brentuximab vedotin, sold under the brand name Adcetris, is an antibody-drug conjugate medication used to treat relapsed or refractory Hodgkin lymphoma (HL) and systemic anaplastic large cell lymphoma (ALCL), a type of T cell non-Hodgkin lymphoma. It selectively targets tumor cells expressing the CD30 antigen, a defining marker of Hodgkin lymphoma and ALCL. The drug is being jointly marketed by Millennium Pharmaceuticals outside the US and by Seattle Genetics in the US.
Crizotinib, sold under the brand name Xalkori among others, is an anti-cancer medication used for the treatment of non-small cell lung carcinoma (NSCLC). It acts as an ALK and ROS1 inhibitor.
Mogamulizumab, sold under the brand name Poteligeo, is a humanized, afucosylated monoclonal antibody targeting CC chemokine receptor 4 (CCR4). The U.S. Food and Drug Administration (FDA) approved it in August 2018 for treatment of relapsed or refractory mycosis fungoides and Sézary disease. It was approved in Japan in 2012, for the treatment of relapsed or refractory CCR4+ adult T-cell leukemia/lymphoma (ATCLL) and in 2014, for relapsed or refractory CCR4+ cutaneous T cell lymphoma (CTCL). The latter approval was based on study with 28 subjects.
Dinutuximab and dinutuximab beta are monoclonal antibodies used as a second-line treatment for children with high-risk neuroblastoma. Each antibody is made of both mouse and human components and targets glycolipid GD2, expressed on neuroblastoma cells and on normal cells of neuroectodermal origin, including the central nervous system and peripheral nerves. They differ in that dinutuximab is manufactured using mouse cells, and dinutuximab beta is manufactured using hamster cells. The dosing regime differs, and dinutuximab is given in combination with granulocyte-macrophage colony stimulating factor (GM-CSF), interleukin-2 (IL-2) and 13-cis-retinoic acid (RA), while dinutuximab beta can be given alone.
Tucidinostat is a histone deacetylase inhibitor (HDI) developed in China. It was also known as HBI-8000. It is a benzamide HDI and inhibits Class I HDAC1, HDAC2, HDAC3, as well as Class IIb HDAC10.
Juno Therapeutics Inc is an American biopharmaceutical company founded in 2013 through a collaboration of the Fred Hutchinson Cancer Research Center, Memorial Sloan-Kettering Cancer Center and pediatrics partner Seattle Children's Research Institute. The company was launched with an initial investment of $120 million, with a remit to develop a pipeline of cancer immunotherapy drugs. The company raised $300 million through private funding and a further $265 million through their IPO.
Duvelisib, sold under the brand name Copiktra, is a medication used to treat chronic lymphocytic leukemia (CLL), small lymphocytic lymphoma (SLL), and follicular lymphoma after other treatments have failed. It is taken by mouth. It is a PI3 kinase inhibitor.
Axicabtagene ciloleucel, sold under the brand name Yescarta, is a medication used for the treatment for large B-cell lymphoma that has failed conventional treatment. T cells are removed from a person with lymphoma and genetically engineered to produce a specific T-cell receptor. The resulting chimeric antigen receptor T cells (CAR-Ts) that react to the cancer are then given back to the person to populate the bone marrow. Axicabtagene treatment carries a risk for cytokine release syndrome (CRS) and neurological toxicities.
Umbralisib, sold under the brand name Ukoniq, is an anti-cancer medication for the treatment of marginal zone lymphoma (MZL) and follicular lymphoma (FL). It is taken by mouth.
Loncastuximab tesirine, sold under the brand name Zynlonta, is a monoclonal antibody conjugate medication used to treat large B-cell lymphoma and high-grade B-cell lymphoma. It is an antibody-drug conjugate (ADC) composed of a humanized antibody targeting the protein CD19.
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.
Mature T-cell lymphoma, also called peripheral T-cell lymphoma, is a group of rare, aggressive lymphomas that develop from mature white blood cells and originate from lymphoid tissues outside of the bone marrow. Mature T-cell lymphoma is under the category of non-Hodgkin lymphoma. Mature T-cell lymphomas account for 10% to 15% of all lymphomas and is more common in Asia than in Europe and America. Its common subtypes include angioimmunoblastic T-cell lymphoma, anaplastic large cell lymphoma and peripheral T-cell lymphoma not otherwise specified. While different subtypes have variable symptoms, common symptoms include enlarged painless lymph nodes, fever, weight loss, rash and night sweats.
Darinaparsin is a drug for the treatment of various types of cancer. It is an arsenic-containing derivative of glutathione.
