Pyxis Oncology to Present New PYX-201, PYX-106 and PYX-102 Preclinical Data at AACR Annual Meeting

PYX-201, an EDB+FN-specific tumor stroma-targeting ADC, demonstrates potent anti-tumor efficacy across multiple human cancers in PDX tumor models

The PYX-201 target EDB+FN is found overexpressed across multiple human solid tumor types

BOSTON, March 05, 2024 (GLOBE NEWSWIRE) -- Pyxis Oncology, Inc. (Nasdaq: PYXS), a clinical stage company focused on developing next generation therapeutics to target difficult-to-treat cancers, announced today that the company will present new preclinical data in four posters at the 2024 American Association for Cancer Research (AACR) Annual Meeting in San Diego, California, held from April 5 to 10, 2024.

"Our preclinical research continues to support the broad potential of PYX-201, our innovative clinical stage ADC targeting EDB+FN, a protein associated with the stroma of solid tumors,” said Lara S. Sullivan, M.D., President and Chief Executive Officer of Pyxis Oncology. “Data from PDX tumor preclinical models has shown potent anti-tumor activity in multiple human cancer indications. We will also demonstrate that the overexpression of EDB+FN, the molecular target of PYX-201, is consistently observed in various human tumor types, with minimal expression observed in healthy tissue. For our PYX-106 program, we will also present encouraging preclinical data supporting the clinical opportunity of this immune-oncology therapeutic candidate to potentially demonstrate clinical activity in individuals that are not candidates for anti-PD-(L)1 approaches. Finally, we will present anti-tumor efficacy data supporting the potential for PYX-102 as a therapeutic candidate, and remain open to out-licensing opportunities for future development.”

Poster titles are now available on the AACR website. Posters will be made available on the Pyxis Oncology website following presentations at the conference. Presentation details are as follows; times noted are Pacific time:
