In recent years, the treatment of primary biliary cholangitis (PBC) has seen remarkable progress, with the continuous introduction of new drugs bringing good news to PBC patients worldwide. According to reports from authoritative institutions, the global PBC treatment market is thriving and is expected to experience explosive growth in the coming years. However, despite the fact that three PBC treatment drugs have already been approved, the market still has a significant unmet need, and the industry's expectations for new therapeutic drugs are becoming increasingly urgent.
First, let's understand the three PBC treatment drugs currently on the market. Ursodeoxycholic acid (UDCA) is the recognized first-line treatment drug and has been widely used in clinical practice for many years. However, it is regrettable that about 40% of patients do not respond well to this treatment, leaving them in urgent need of more effective treatment options. Against this backdrop, Ocaliva and Elafibranor emerged, being approved as second-line treatment options for PBC in 2016 and 2021, respectively. The introduction of these two drugs has undoubtedly brought new hope to PBC patients.
However, market competition has not stopped. Industry insiders generally believe that Seladelpar has the potential to become the fourth novel PBC drug approved globally. Seladelpar is an oral, potent, and selective PPARδ agonist, and its unique mechanism of action gives it significant advantages in regulating bile acid synthesis, inflammation, fibrosis, and lipid metabolism. Based on preclinical and clinical data, Seladelpar has demonstrated good efficacy and safety in the treatment of PBC. Currently, the drug is undergoing priority review in the United States and is expected to receive approval for marketing in August 2024. At that time, it is expected to bring a safer and more effective treatment option to PBC patients worldwide.
In addition to Seladelpar, the industry is also paying attention to other PBC drug candidates in development. For example, Setanaxib is a new drug that targets NOX4 and NOX1, and it has unique potential in the field of PBC treatment. Furthermore, domestic pharmaceutical companies are also actively engaged in the development of PBC drug research, such as the dual-target peptide drug TB001 developed by a well-known pharmaceutical company. The successive launch of these candidate drugs will bring new development opportunities to the PBC treatment market.
It is worth mentioning that with the advancement of technology and the depth of research, the PBC treatment field is facing unprecedented development opportunities. More and more new drugs and new technologies are emerging, bringing more treatment options to PBC patients. At the same time, as global medical standards improve and medical resources are optimized, the treatment experience of PBC patients will also be significantly improved. We have reason to believe that in the near future, PBC patients will be able to enjoy safer, more effective, and more convenient treatment services.
