SOUTH SAN FRANCISCO, CA, September 5, 2023 – Star Therapeutics, a biotechnology company interrogating novel biology to develop life-changing therapies, today announced the closing of an oversubscribed $90 million Series C financing to continue growth of its first-in-class antibody therapies and portfolio companies.
