Pegfilgrastim, sold under the brand name Neulasta among others, is a PEGylated form of the recombinant human granulocyte colony-stimulating factor (GCSF) analog filgrastim. [16] It serves to stimulate the production of white blood cells (neutrophils). [16] [18] Pegfilgrastim was developed by Amgen. [19]
Pegfilgrastim treatment can be used to stimulate bone marrow to produce more neutrophils to fight infection in patients undergoing chemotherapy. [20]
Pegfilgrastim has a human half-life of 15 to 80 hours, much longer than the parent filgrastim (3–4 hours). [21] [20]
Pegfilgrastim was approved for medical use in the United States in January 2002, in the European Union in August 2002, and in Australia in September 2002. [19] [17] [22] [23] [24] It is on the World Health Organization's List of Essential Medicines. [25]
Pegfilgrastim is indicated to decrease the incidence of infection, as manifested by febrile neutropenia, in people with non-myeloid malignancies receiving myelosuppressive anti-cancer drugs associated with a clinically significant incidence of febrile neutropenia; and to increase survival in people acutely exposed to myelosuppressive doses of radiation (hematopoietic subsyndrome of acute radiation syndrome). [16] [26] [27]
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.
Adalimumab, sold under the brand name Humira and others, is a disease-modifying antirheumatic drug and monoclonal antibody used to treat rheumatoid arthritis, juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn's disease, ulcerative colitis, plaque psoriasis, hidradenitis suppurativa, and uveitis. It is administered by subcutaneous injection. It works by inactivating tumor necrosis factor-alpha (TNFα).
Ofatumumab is a fully human monoclonal antibody to CD20, which appears to provide rapid B-cell depletion. Under the brand name Kesimpta, it is approved for the treatment of multiple sclerosis in the United States as well as in the European Union and other regions. Under the brand name Arzerra, it is approved for the treatment of certain types of chronic lymphocytic leukemia (CLL) in the United States. It is sold by Novartis under license from Genmab.
Insulin aspart, sold under the brand name NovoLog, among others, is a modified type of medical insulin used to treat type 1 and type 2 diabetes. It is generally used by injection under the skin but may also be used by injection into a vein. Maximum effect occurs after about 1–3 hours and lasts for 3–5 hours. Generally a longer-acting insulin like insulin NPH is also needed.
A biosimilar is a biologic medical product that is almost an identical copy of an original product that is manufactured by a different company. Biosimilars are officially approved versions of original "innovator" products and can be manufactured when the original product's patent expires. Reference to the innovator product is an integral component of the approval.
