Ponsegromab
Ponsegromab (PF-06946860) is a monoclonal antibody that works as a GDF-15 inhibitor. It is developed by Pfizer for cancer cachexia Cachexia () is a syndrome that happens when people have certain illnesses, causing muscle loss that cannot be fully reversed with improved nutrition. It is most common in diseases like cancer, congestive heart failure, chronic obstructive pul .... In September 2024, Pfizer disclosed that ponsegromab led to significant body weight increases in patients with non-small cell lung cancer, pancreatic cancer, or colorectal cancer in a phase 2 clinical trial.

GDF-15
Growth/differentiation factor 15 is a protein that in humans is encoded by the GDF15 gene. GDF15 was first identified as Macrophage inhibitory cytokine-1 or MIC-1. It is a protein belonging to the transforming growth factor beta superfamily. Under normal conditions, GDF15 is expressed in low concentrations in most organs and upregulated because of injury of organs such as liver, kidney, heart and lung. Function The function of GDF15 is not fully clear but it seems to have a role in regulating inflammatory pathways and to be involved in regulating apoptosis, angiogenesis, cell repair and cell growth, which are biological processes observed in cardiovascular and neoplastic disorders. Clinical significance GDF15 has shown to be a strong prognostic protein in patients with different diseases such as heart diseases and cancer. In cardiovascular tissues it is shown that GDF15 concentrations increase in response to atherosclerosis, ischemia/reperfusion injury and heart failur ...

Monoclonal Antibody
A monoclonal antibody (mAb, more rarely called moAb) is an antibody produced from a cell lineage made by cloning a unique white blood cell. All subsequent antibodies derived this way trace back to a unique parent cell. Monoclonal antibodies are identical and can thus have monovalent affinity, binding only to a particular epitope (the part of an antigen that is recognized by the antibody). In contrast, polyclonal antibodies are mixtures of antibodies derived from multiple plasma cell lineages which each bind to their particular target epitope. Artificial antibodies known as bispecific monoclonal antibodies can also be engineered which include two different antigen binding sites ( FABs) on the same antibody. It is possible to produce monoclonal antibodies that specifically bind to almost any suitable substance; they can then serve to detect or purify it. This capability has become an investigative tool in biochemistry, molecular biology, and medicine. Monoclonal antibod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pfizer
Pfizer Inc. ( ) is an American Multinational corporation, multinational Pharmaceutical industry, pharmaceutical and biotechnology corporation headquartered at The Spiral (New York City), The Spiral in Manhattan, New York City. Founded in 1849 in New York by German entrepreneurs Charles Pfizer (1824–1906) and Charles F. Erhart (1821–1891), Pfizer is one of the oldest pharmaceutical companies in North America. Pfizer develops and produces medicines and vaccines for immunology, oncology, cardiology, endocrinology, and neurology. The company's largest products by sales are the Pfizer–BioNTech COVID-19 vaccine ($11 billion in 2023 revenues), apixaban ($6 billion in 2023 revenues), a pneumococcal conjugate vaccine ($6 billion in 2023 revenues), palbociclib ($4 billion in 2023 revenues), and tafamidis ($3 billion in 2023 revenues). In 2023, 46% of the company's revenues came from the United States, 6% came from Japan, and 48% came from other countries. Pfizer has been a publi ...

Cancer Cachexia
Cachexia () is a syndrome that happens when people have certain illnesses, causing muscle loss that cannot be fully reversed with improved nutrition. It is most common in diseases like cancer, congestive heart failure, chronic obstructive pulmonary disease, chronic kidney disease, and AIDS. These conditions change how the body handles inflammation, metabolism, and brain signaling, leading to muscle loss and other harmful changes to body composition over time. Unlike weight loss from not eating enough, cachexia mainly affects muscle and can happen with or without fat loss. Diagnosis of cachexia is difficult because there are no clear guidelines, and its occurrence varies from one affected person to the next. Like malnutrition, cachexia can lead to worse health outcomes and lower quality of life. Definition Cachexia is hard to define because it often happens alongside malnutrition and sarcopenia. Since there are no clear rules separating these conditions, experts continue work ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monoclonal Antibodies
A monoclonal antibody (mAb, more rarely called moAb) is an antibody produced from a Lineage (evolution), cell lineage made by cloning a unique white blood cell. All subsequent antibodies derived this way trace back to a unique parent cell. Monoclonal antibodies are identical and can thus have Valence (chemistry), monovalent affinity, binding only to a particular epitope (the part of an antigen that is recognized by the antibody). In contrast, polyclonal antibodies are mixtures of antibodies derived from multiple plasma cell lineages which each bind to their particular target epitope. Artificial antibodies known as bispecific monoclonal antibodies can also be engineered which include two different antigen binding sites (Fragment antigen-binding region, FABs) on the same antibody.
