Rabacfosadine, sold under the brand name Tanovea, is a guanine nucleotide analog used for the treatment of lymphoma in dogs. [1] It was developed by Gilead Sciences as GS-9219. [2]
The active form of rabacfosadine is a chain-terminating inhibitor of the major deoxyribonucleic acid (DNA) polymerases. In vitro studies have demonstrated that rabacfosadine inhibits DNA synthesis, resulting in S phase arrest and induction of apoptosis. [3] It also inhibits the proliferation of lymphocytes in dogs with naturally occurring lymphoma. [4]
Rabacfosadine was granted conditional approval by the US Food and Drug Administration (FDA) in December 2016, [5] and became the first medication to receive full approval for the treatment of canine lymphoma in July 2021. [6]
In July 2021, the U.S. Food and Drug Administration (FDA) approved Tanovea to treat lymphoma in dogs. [6] Lymphoma, also called lymphosarcoma, is a type of cancer that can affect many species, including dogs. [6] Rabacfosadine is the first conditionally approved new animal drug for dogs to achieve the FDA's full approval. [6]
Common side effects of rabacfosadine are decreased white blood cell count, diarrhea, vomiting, decreased appetite or loss of appetite, weight loss, decreased activity level, and skin problems. Other side effects may occur. [5]
Rituximab, sold under the brand name Rituxan among others, is a monoclonal antibody medication used to treat certain autoimmune diseases and types of cancer. It is used for non-Hodgkin lymphoma, chronic lymphocytic leukemia, rheumatoid arthritis, granulomatosis with polyangiitis, idiopathic thrombocytopenic purpura, pemphigus vulgaris, myasthenia gravis and Epstein–Barr virus-positive mucocutaneous ulcers. It is given by slow intravenous infusion.
Cancer immunotherapy (immuno-oncotherapy) is the stimulation of the immune system to treat cancer, improving the immune system's natural ability to fight the disease. It is an application of the fundamental research of cancer immunology (immuno-oncology) and a growing subspecialty of oncology.
Melphalan, sold under the brand name Alkeran among others, is a chemotherapy medication used to treat multiple myeloma; malignant lymphoma; lymphoblastic and myeloblastic leukemia; childhood neuroblastoma; ovarian cancer; mammary adenocarcinoma; and uveal melanoma. It is taken by mouth or by injection into a vein.
Bendamustine, sold under the brand name Treanda among others, is a chemotherapy medication used in the treatment of chronic lymphocytic leukemia (CLL), multiple myeloma, and non-Hodgkin's lymphoma. It is given by injection into a vein.
Panobinostat, sold under the brand name Farydak, is a medication used for the treatment of multiple myeloma. It is a hydroxamic acid and acts as a non-selective histone deacetylase inhibitor.
Toceranib (INN), sold under the brand name Palladia, is a receptor tyrosine kinase inhibitor that is used in the treatment of canine mast cell tumor also called mastocytoma. It is the first medication developed specifically for the treatment of cancer in dogs. It is used as its phosphate salt, toceranib phosphate. It was developed by SUGEN as SU11654, a sister compound to sunitinib, which was later approved for human therapies. Toceranib is a tyrosine kinase inhibitor and works in two ways: by killing tumor cells and by cutting off the blood supply to the tumor.
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 Seagen in the US.
Rucaparib, sold under the brand name Rubraca, is a PARP inhibitor used as an anti-cancer agent. Rucaparib is a first-in-class pharmaceutical drug targeting the DNA repair enzyme poly-ADP ribose polymerase-1 (PARP-1). It is taken by mouth.
Phosphoinositide 3-kinase inhibitors are a class of medical drugs that are mainly used to treat advanced cancers. They function by inhibiting one or more of the phosphoinositide 3-kinase (PI3K) enzymes, which are part of the PI3K/AKT/mTOR pathway. This signal pathway regulates cellular functions such as growth and survival. It is strictly regulated in healthy cells, but is always active in many cancer cells, allowing the cancer cells to better survive and multiply. PI3K inhibitors block the PI3K/AKT/mTOR pathway and thus slow down cancer growth. They are examples of a targeted therapy. While PI3K inhibitors are an effective treatment, they can have very severe side effects and are therefore only used if other treatments have failed or are not suitable.
Mogamulizumab, sold under the brand name Poteligeo, is a humanized, afucosylated monoclonal antibody targeting CC chemokine receptor type 4 (CCR4). It is given by injection into a vein.
Ibrutinib, sold under the brand name Imbruvica among others, is a small molecule drug that inhibits B-cell proliferation and survival by irreversibly binding the protein Bruton's tyrosine kinase (BTK). Blocking BTK inhibits the B-cell receptor pathway, which is often aberrantly active in B cell cancers. Ibrutinib is therefore used to treat such cancers, including mantle cell lymphoma, chronic lymphocytic leukemia, and Waldenström's macroglobulinemia. Ibrutinib also binds to C-terminal Src Kinases. These are off-target receptors for the BTK inhibitor. Ibrutinib binds to these receptors and inhibits the kinase from promoting cell differentiation and growth. This leads to many different side effects like left atrial enlargement and atrial fibrillation during the treatment of Chronic Lymphocytic Leukemia.
Nivolumab, sold under the brand name Opdivo, is an anti-cancer medication used to treat a number of types of cancer. This includes melanoma, lung cancer, malignant pleural mesothelioma, renal cell carcinoma, Hodgkin lymphoma, head and neck cancer, urothelial carcinoma, colon cancer, esophageal squamous cell carcinoma, liver cancer, gastric cancer, and esophageal or gastroesophageal junction cancer. It is administered intravenously.
Pembrolizumab, sold under the brand name Keytruda, is a humanized antibody, more specifically a PD-1 Inhibitor, used in cancer immunotherapy that treats melanoma, lung cancer, head and neck cancer, Hodgkin lymphoma, stomach cancer, cervical cancer, and certain types of breast cancer. It is administered by slow intravenous injection.
Idelalisib, sold under the brand name Zydelig, is a medication used to treat certain blood cancers. Idelalisib acts as a phosphoinositide 3-kinase inhibitor; more specifically, it blocks P110δ, the delta isoform of the enzyme phosphoinositide 3-kinase. It was developed by Gilead Sciences. It is taken orally.
Copanlisib, sold under the brand name Aliqopa, is a medication used for the treatment of adults experiencing relapsed follicular lymphoma who have received at least two prior systemic therapies.
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.
Tazemetostat, sold under the brand name Tazverik, is a medication used for the treatment of adults and adolescents aged 16 years and older with metastatic or locally advanced epithelioid sarcoma not eligible for complete resection.
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.
Adagrasib, sold under the brand name Krazati, is an anticancer medication used to treat non-small cell lung cancer. Adagrasib is an inhibitor of G12C mutated KRAS GTPase. It is taken by mouth. It is being developed by Mirati Therapeutics.
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.
