Evanston Pharma Inc was founded in 2003 and rebranded as Evanstoninc LLC in 2012. It initially focused on API sales and recently shifted its focus to consulting and preparation product entry into the US market. The company has helped numerous Chinese companies to gain FDA approval and establish sales for their API products. Additionally, two Chinese companies have successfully entered the US market with their preparation products, with stable sales, through Evanstoninc's agency. One of these companies is a publicly listed firm in Zhejiang, while the other is based in Jiangsu. There is also a Zhejiang-based listed company with a product awaiting FDA on-site inspection and a completed sales contract.
