Sept 14 (Reuters) – Drug developer Electra Therapeutics is targeting a valuation of up to $977.6 million in its U.S. initial public ​offering, according to a filing on ‌Monday, extending a comeback in biotech listings this year.

The South San Francisco, California-based company is seeking to raise as much as $346.7 million by offering about ‌21.67 ​million shares priced between $14 ⁠and $16 apiece.

Here are some ⁠more details:

• The listing comes as the typically busy fall IPO window has been slower than last year due to macroeconomic ​uncertainty and market volatility, although biotech offerings have broadly rebounded.

• Electra Therapeutics, a ⁠late-clinical-stage biotech company, develops therapies ⁠that target signal regulatory proteins ​to treat immunological diseases and cancer.

• Its lead ​experimental drug, ipsoprubart, targets harmful immune cells ‌involved in secondary hemophagocytic lymphohistiocytosis, a severe condition that causes the immune system to become dangerously overactive. The drug is being tested ⁠in a global study intended to support approval.

• Electra plans to use the IPO proceeds to ⁠fund clinical ‌trials for ipsoprubart, advance its second ⁠drug candidate, ELA822, and support ​its ‌working capital and other corporate needs.

• ​The company ⁠plans to list its shares on Nasdaq under the symbol “ETRA.”

• Jefferies, TD Cowen, Evercore ISI and Cantor are the underwriters for the offering.
