ADARx Pharmaceuticals has officially filed for a U.S. initial public offering, aiming for a valuation of $1.74 billion. The company intends to list on the Nasdaq under the ticker symbol ADRX as interest in the biotech sector grows.

The move signals a strengthening investor appetite for biotech listings in the United States. AbbVie has already bolstered confidence in the company by agreeing to purchase a 4.9% stake through a concurrent private placement.
The company is offering 21.9 million shares priced between $15 and $17 per share. This offering is managed by a syndicate of underwriters including JP Morgan, Morgan Stanley, TD Cowen, UBS Investment Bank, and LifeSci Capital.

It positions ADARx to compete for capital alongside established rivals in a sector that is increasingly defined by strategic partnerships between startups and industry giants.
