<span class="mw-page-title-main">Trastuzumab</span> Medication

Trastuzumab, sold under the brand name Herceptin among others, is a monoclonal antibody used to treat breast cancer and stomach cancer. It is specifically used for cancer that is HER2 receptor positive. It may be used by itself or together with other chemotherapy medication. Trastuzumab is given by slow injection into a vein and injection just under the skin.

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).

<span class="mw-page-title-main">Cetuximab</span> Pharmaceutical drug

Cetuximab, sold under the brand name Erbitux, is an epidermal growth factor receptor (EGFR) inhibitor medication used for the treatment of metastatic colorectal cancer and head and neck cancer. Cetuximab is a chimeric (mouse/human) monoclonal antibody given by intravenous infusion.

<span class="mw-page-title-main">Monoclonal antibody therapy</span> Form of immunotherapy

Monoclonal antibodies (mAbs) have varied therapeutic uses. It is possible to create a mAb that binds specifically to almost any extracellular target, such as cell surface proteins and cytokines. They can be used to render their target ineffective, to induce a specific cell signal, to cause the immune system to attack specific cells, or to bring a drug to a specific cell type.

<span class="mw-page-title-main">Pertuzumab</span> Pharmaceutical drug

Pertuzumab, sold under the brand name Perjeta, is a monoclonal antibody used in combination with trastuzumab and docetaxel for the treatment of metastatic HER2-positive breast cancer; it also used in the same combination as a neoadjuvant in early HER2-positive breast cancer.

Labetuzumab is a humanized IgG1 monoclonal antibody for the treatment of colorectal cancer. It selectively binds to carcinoembryonic cell adhesion molecule 5.

Medarex was an American biopharmaceutical company based in Princeton, New Jersey, with manufacturing facilities in Bloomsbury and Annandale, New Jersey, and research facilities in Milpitas and Sunnyvale, California. In 2009, Medarex was purchased by Bristol Myers Squibb.

Triple-negative breast cancer (TNBC) is any breast cancer that either lacks or shows low levels of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) overexpression and/or gene amplification. Triple-negative is sometimes used as a surrogate term for basal-like.

Leronlimab is a humanized monoclonal antibody targeted against the CCR5 receptor found on T lymphocytes of the human immune system. It is being investigated as a potential therapy in the treatment of COVID-19, triple negative breast cancer, and HIV infection. The United States Food and Drug Administration has designated PRO 140 for fast-track approval. In February 2008, the drug entered Phase 2 clinical trials and a phase 3 trial was begun in 2015. In February 2018, Cytodyn Inc reported that the primary endpoint had been achieved in the PRO 140 pivotal combination therapy trial in HIV infection. In 2020 CytoDyn submitted a fast-track biologics license application for treatment of CCR5-tropic HIV-1 Infection.

Milatuzumab is an anti-CD74 humanized monoclonal antibody for the treatment of multiple myeloma non-Hodgkin's lymphoma and chronic lymphocytic leukemia.

Veltuzumab is a monoclonal antibody which is being investigated for the treatment of non-Hodgkin's lymphoma. As of December 2011, it is undergoing Phase I/II clinical trials. When used with milatuzumab it showed activity.

Glembatumumab vedotin is an antibody-drug conjugate (ADC) that targets cancer cells expressing transmembrane glycoprotein NMB (GPNMB).

<span class="mw-page-title-main">Antibody–drug conjugate</span> Class of biopharmaceutical drugs

Antibody–drug conjugates or ADCs are a class of biopharmaceutical drugs designed as a targeted therapy for treating cancer. Unlike chemotherapy, ADCs are intended to target and kill tumor cells while sparing healthy cells. As of 2019, some 56 pharmaceutical companies were developing ADCs.

<span class="mw-page-title-main">Trastuzumab emtansine</span> Pharmaceutical drug

Trastuzumab emtansine, sold under the brand name Kadcyla, is an antibody-drug conjugate consisting of the humanized monoclonal antibody trastuzumab (Herceptin) covalently linked to the cytotoxic agent DM1. Trastuzumab alone stops growth of cancer cells by binding to the HER2 receptor, whereas trastuzumab emtansine undergoes receptor-mediated internalization into cells, is catabolized in lysosomes where DM1-containing catabolites are released and subsequently bind tubulin to cause mitotic arrest and cell death. Trastuzumab binding to HER2 prevents homodimerization or heterodimerization (HER2/HER3) of the receptor, ultimately inhibiting the activation of MAPK and PI3K/AKT cellular signalling pathways. Because the monoclonal antibody targets HER2, and HER2 is only over-expressed in cancer cells, the conjugate delivers the cytotoxic agent DM1 specifically to tumor cells. The conjugate is abbreviated T-DM1.

Yttrium (90Y) clivatuzumab tetraxetan is a humanized monoclonal antibody-drug conjugate designed for the treatment of pancreatic cancer. The antibody part, clivatuzumab, is conjugated with tetraxetan, a chelator for yttrium-90, a radioisotope which destroys the tumour cells.

Seagen Inc. is an American biotechnology company focused on developing and commercializing innovative, empowered monoclonal antibody-based therapies for the treatment of cancer. The company, headquartered in Bothell, Washington, is the industry leader in antibody-drug conjugates or ADCs, a technology designed to harness the targeting ability of monoclonal antibodies to deliver cell-killing agents directly to cancer cells. Antibody-drug conjugates are intended to spare non-targeted cells and thus reduce many of the toxic effects of traditional chemotherapy, while potentially enhancing antitumor activity.

Enfortumab vedotin, sold under the brand name Padcev, is an antibody-drug conjugate used for the treatment of urothelial cancer. It is a nectin-4-directed antibody and microtubule inhibitor conjugate. Enfortumab refers to the monoclonal antibody part, and vedotin refers to the payload drug (MMAE) and the linker.

<span class="mw-page-title-main">Sacituzumab govitecan</span> Antibody-drug conjugate

Sacituzumab govitecan, sold under the brand name Trodelvy by Gilead Sciences, 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.

<span class="mw-page-title-main">Loncastuximab tesirine</span> Medication

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.

<span class="mw-page-title-main">Trastuzumab deruxtecan</span> Medication

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.
