US-based cancer therapy developer Pyxis Oncology secured $168m in an upsized initial public offering on Friday representing exits for pharmaceutical firms Bayer, Pfizer and Ipsen.
The company issued 10.5 million shares on the Nasdaq Global Select Market priced at the top of its $14 to $16 range. They opened at $18.88 but crashed to $13.20 by the end of its first day of trading.
Pyxis is developing antibody-drug conjugates (ADCs) and immunotherapies for cancers that are difficult to treat, advancing work by Thomas Gajewski, the AbbVie Foundation professor of pathology at University of Chicago.
A total of $140m has been allocated to the preclinical development of the company’s three cancer drug candidates and, should these be successful, the clinical trials. Capital is also going towards drug discovery programmes, the in-licensing of assets and other business activities.
Pyxis received $152m in a March 2021 series B round co-led by Arix Bioscience and RTW Investments that included Ipsen, Pfizer and Bayer, the last two through Pfizer Ventures and Leaps by Bayer respectively.
Perceptive Advisors, RA Capital Management, BVF Partners, Janus Henderson Investors, Cormorant Asset Management, HBM Healthcare Investments, Acuta Capital Partners, Ridgeback Capital Investments and Surveyor Capital also took part in the series B round.
The participants were filled out by Laurion Capital Management, Logos Capital, LifeSci Venture Partners, funds managed by Tekla Capital Management, Longwood Fund and Agent Capital.
The company had attracted $22m in a 2019 series A round led by Leaps by Bayer that included Ipsen, UChicago’s Startup Investment Program, Longwood Fund and Agent Capital.
Pfizer remains Pyxis’s largest shareholder following the IPO with an 8.8% stake. Bayer owns 8.4%, Perceptive Advisors 4.7%, Arix Bioscience and RTW Investments 4.4% each, RA Capital 3.9% and Longwood Fund 3.7%.
