June 4 (Reuters) – Biopharmaceutical company Parabilis Medicines said on Thursday it is aiming to raise ​as much as $475 million in ‌its U.S. initial public offering.

The summer IPO market has gathered momentum after a choppy start to the year, with ‌a ​string of well-received ⁠listings encouraging more ⁠companies to test investor appetite.

Parabilis is a clinical-stage biopharmaceutical company that is developing Helicons, a novel ​class of stabilized helical peptides designed to attack and modulate ⁠proteins that have ⁠historically been difficult to target ​with conventional medicines.

The company is aiming ​to sell 25 million shares in ‌the offering priced between $17 and $19 apiece.

It is using its proprietary platform to develop therapies for diseases ⁠driven by some hard-to-target proteins, Parabilis said in its IPO prospectus.

After the offering ⁠closes, ‌Parabilis’ stock will trade ⁠on the Nasdaq under the ​ticker ‌symbol “PBLS.”

Leerink Partners, BofA Securities, ​Evercore ISI, ⁠Guggenheim Securities and LifeSci Capital are the lead underwriters of the offering.
