CRTH2, or Chemoattractant receptor-homologous molecule expressed on TH2 cells or T Helper cells, is a G-protein coupled receptor. It is also expressed in basophils, eosinophils, and innate lymphoid cells. Prostaglandin D2 acts as a ligand on this receptor and mediates the production of type-2 cytokines like IL-4, IL-5, and IL-13, chemotaxis, and apoptosis. The PGD2-CRTH2 pathway is considered important for the development of allergic inflammation. Hence, CRTH2 Antagonists are used for controlling asthma due to allergies. Many candidates are in the pipeline for various indications for which CRTH2 Antagonists could be a possible treatment approach, like Asthma, Hypersensitivity, Dermatitis, Rhinitis, and others. To prevent and treat these diseases, businesses are looking for fresh, unique chemicals. Over the upcoming years, the THF dehydrogenase Inhibitor market will have a large increase in revenue due to the discovery and introduction of fresh products by industry participants.  According to the Asthma and Allergy Foundation of America, in 2021, about 25 million people were suffering from Asthma (about 1 in every 13 Americans). About 5 million American children have asthma, according to the same report. Therefore, there is a rising trend in the prevalence of diseases in the CRTH2 Antagonists market and is an opportunity for the same.

Several of these inhibitors are on the market, while many are in ongoing clinical trials. 18 companies have various products in their pipelines, with 20 products in various stages of clinical trials. 3 products are in Phase 3, 7 products are in Phase 2, and 10 products are in Phase 1 of the clinical trials.

Key Market Developments:

  • In October 2018, Novartis drug Fevipiprant (QAW039 an oral competitive antagonist of CRTH2 have demonstrated safety and potential efficacy in patients with asthma, specifically, improvement in FEV1 and eosinophilic airway inflammation in Early-phase trials.
