The Company's pipeline includes a number of upcoming blockbuster products. Among them,the new drug applications (NDAs) on new formulations or indications of three core products have been accepted. The anti-TNF α pre-filled aqueous injection solution of Yisaipu (301S) will address limitations of the powder injection,and will significantly improve the treatment compliance among hundreds of thousands of medical professionals and patients. Minoxidil foam(MN709) is the only one of its kind domestically,adding a medication choice for hair loss patients with sensitive scalp. The phase III clinical trial of TPIAO for pediatric immune thrombocytopenia (ITP) met the preset primary endpoint,and it is expected to meet the treatment needs of children with ITP. In addition,the candidates acquired via external partnerships also achieved big progress.
