HDAC Inhibitor Market: Competitive Landscape, Pipeline, and Market Analysis 2023
Histone deacetylases (HDAC) are a class of enzymes that remove acetyl groups from an N-acetyl lysine amino acid on both histone and non-histone proteins. HDACs allow histones to wrap the DNA more tightly. This is important because DNA is wrapped around histones and DNA expression is regulated by acetylation and de-acetylation. HDAC's action is opposite to that of histone acetyltransferase. HDAC proteins are now also called lysine deacetylases. HDAC involved biological functions including transcription, metabolism, oxidative stress, redox, protein degradation, and cell cycle among others. Histone deacetylases are expressed in different tumors; class I and II HDACs are general oncoproteins that interact with substrates and regulate gene expression to promote tumorigenesis and cancer development either individually or alongside co-repressors. The mechanism of action (MOA) of HDAC Inhibitor is that work by HDIs block HDAC enzyme activity by binding to the zinc ion in the catalytic site, which blocks substrate access to the site and histone deacetylase inhibitors exert their anti-tumour effects via the induction of expression changes of oncogenes or tumor suppressors. HDAC Inhibitors are used for the treatment of lymphoma, blood coagulation disorders, leukemia, sarcoma, hematologic diseases, Hodgkin disease, gastrointestinal diseases, multiple myeloma, vascular diseases, and breast neoplasm among others. Increased prevalence of sarcoma and lymphoma are the key drivers for the HDAC Inhibitor market. For instance, According to the World Health Organization 2023, Non-Hodgkin lymphoma (NHL) is one of the most common cancers in the United States, accounting for about 4% of all cancers. Launch of newer products by the market players could seek opportunities that influence extensive research and development in HDAC inhibitors. For instance, Chipscreen Bioscience’s Epidaza (Chidamide) is used to treat relapsed or refractory peripheral T cell lymphoma (PTCL). Moreover, the development of novel molecules by key players are coming up to overcome challenges in therapy. For instance, Italfarmaco’s Givinostat (ITF2357) for the treatment of juvenile idiopathy is under the various stages of clinical studies.

The molecules such as Epidaza (Chidamide) developed by Chipscreen Biosciences for the line of treatment for relapsed or refractory peripheral T cell lymphoma (PTCL). 4SC’s Kinselby (Resminostat) is used to treat Cutaneous T-cell lymphoma (CTCL) a rare type of cancer that begins in white blood cells called T cells (T lymphocytes). Moreover, Italfarmaco’s Givinostat (ITF2357) for the therapy of juvenile idiopathic arthritis, Duchenne muscular dystrophy, and Mundipharma’s Tinostamustine (EDO-S101) to improve drug access to DNA strands within cancer cells, break them, and counteract damage repair is under the clinical development.
